                    1.     INTRODUCTION



                    Storm Water Runoff - Its Problem and Its Solutions


                    The water that runs off the land into surface waters during and immediately
                    following a rainfall event is referred to as storm water. In a watershed undergoing
                    urban expansion, the volume of storm water resulting from a particular rainfall
                    event increases because of the reduction in pervious land area (i.e. natural land
                    being covered by pavement, concrete, or buildings) That is, the alteration of natural
                    land cover and land contours to residential, commercial, industrial and even crop
                    land uses results in decreased infiltration of rainfall and an increased rate and
                    volume of runoff.

                    As development has increased, so has the problem of dealing with the increased
                    quantity of stormwater runoff. Failure to properly manage this runoff has resulted
                    in greater flooding, stream channel erosion and siltation, as well as reduced
                    groundwater recharge. This process occurs every time the land development
                    process causes changes in land surface conditions.
                    History has shown that individual land development projects are often viewed as
                    separate incidents, and not necessarily a part of a "a bigger picture." This has also
                    been the case when the individual land development projects are scattered
                    throughout a watershed (and in many different municipalities). However, it is now
                    being observed and verified that this cumulative nature of individual land surface
                    changes dramatically effects flooding conditions.       This cumulative effect of
                    development in some areas has resulted in floodin of both small and large streams
                    with property damages running into the millions ofdollars, even causing loss of life.
                    Therefore, given the distributed and cumulative nature of the land alteration
                    process, a comprehensive (i.e., watershed-level) approach must be taken if a
                    reasonable and practical management and implementation approach and/or
                    strategy is to be successful.


                    Pennsvivania Storm Water Management Act (Act 167)


                    Recognizin@ the need to deal with this serious and growing problem, the
                    Peripsylvania General Assembly enacted Act 167. The statement of legislative
                    findings at the beginning of the Pennsylvania Storm Water Management Act (Act
                    167), sums up the critical interrelationship between land development, accelerated
                    runoff, and floodplain management. Specifically, this statement of legislative
                    findings points out that:

                    1.     Inadequate management of accelerated runoff of storm water resulting from
                           development throughout a watershed increases flood flows and velocity,
                           contributes to erosion and sedimentation, overtaxes the carrying capacity of


                                                                                   ReChesterEngineers

                           carry and control storm water, undermines floodplain management and
                           floodplain control efforts in downstream communities, reduces groundwater
                           recharge, and threatens public health and safety.

                    2.     A comprehensive program of storm water management, including reasonable
                           regulation of development and activities causing accelerated runoff, is
                           fundamental to the public health, safety and welfare and the protection of
                           the people of the Commonwealth, their resources and their environment.

                    Before the enactment of Act 167, storm water management had been oriented
                    primarily towards addressing the increase in peak runoff rates discharging from
                    individual land development sites to protect property immediately downstream.
                    Minimal attention was given to the effects on locations further downstream
                    (frequently because they were located in another municipality), or to designing
                    storm water controls within the context of the entire watershed. Management of
                    storm water also was typically regulated on a municipal level, with little or no
                    designed consistency between adjoining municipalities in the same watershed
                    concerning the types, or degree, of storm runoff control to be practiced.

                    Act 167 changed this approach by instituting a comprehensive program of storm
                    water planning and management -- on a watershed level. The Act requires
                    Pennsylvania counties to prepare and adopt storm water management plans for each
                    watershed located in the county, as designated by the Pennsylvania Department of
                    Environmental Resources (DEPARTMENT). Most importantly, these plans are to
                    be prepared in consultation with municipalities located in the watershed, working
                    through a Watershed Plan Advisory Committee (WPAQ. The plans are to provide
                    for uniform technical standards and criteria throughout a watershed for the
                    management of storm water runoff from new land developing sites.

                    The types and degree of controls that are prescribed in the watershed plan need to
                    be based on the expected development pattern and hydrologic characteristics of
                    each individual watershed. The management plan, specifically the standards and
                    criteria, are to be developed from the technical evaluations performed in the
                    planning process, in order to respond to the "cause and effect" nature of existing and
                    potential storm runoff impacts in the watershed. The final product of the Act 167
                    watershed planning process is to be a comprehensive and practical implementation
                    plan, developed with a firm sensitivity to the overall needs (e.g., financial, legal,
                    political, technical, etc.) of the municipalities of the watershed, so that a common
                    goal of area wide flood impacts management can be achieved.

                    Lake Erie Watershed Characteristics



                    General Information


                    The Lake Erie Watershed encompasses approximately 230 square miles in
                    northwestern Pennsylvania. Very small portions of the extremities of several of the
                    streams lie within the states of Ohio and New York. The general location of the

                    Topography


                    The topography of the Lake Erie Watershed consists of a steep bluff, rising abruptly
                    at the shore of Lake Erie to as much as 180 feet above the lake, a relatively flat
                    plain extending about two miles inland from the lake and a steep slope beginning
                    three to four miles inland beyond which the land rises gradually into rolling hills
                    which extend to the watershed divide. The watershed divide is characterized by a
                    relatively flat plain which drains very slowly and is comprised of several small ponds
                    and a number of wetlands.


                    Hydrology


                    The headwaters of streams in the Lake Erie drainage basin begin as small
                    meandering channels. In the lower reaches, most of the streams have cut through
                    the glacial till down to bedrock and can be characterized by deep gorges with steep
                    sides and no adjacent flood plain.

                    There are a several dams / reservoirs within the watershed which may have an
                    impact upon wet weather stream flows and, consequently, watershed storm water
                    management standards and criteria.             The Pennsylvania Department of
                    Environmental Resources' Bulletin No. 5 Dams, Reservoirs and Natural Lakes lists
                    the following dams / reservoirs within the watershed:

                           0      Grahaniville Reservoir, located on East Branch Sixteenmile Creek,
                                  with a drainage area of 1.7 square miles.

                           0      Supply dam, located on Sixteenmile Creek, with a drainage area of 9.3
                                  square miles.

                           E      Smith Reservoir, located on West Branch Sixteenmile Creek, with a
                                  drainage area of 2.2 square miles.

                           0      Unnamed dam, located on an unnamed stream immediately east of
                                  the Walnut Creek watershed, with a drainage area of 1.3 square miles.

                           E      Golf Course Dam, located on Sevenmile Creek, with a drainage area
                                  of 4.0 square miles.
                    The following four USGS stream gages are located in the Lake Erie watershed:

                    The first two stations are continuous record stations       which collect data on a
                    regularly scheduled basis. The gages are water stage        recorders which measure
                    hourly stream flows. Thus, measured hourly hydrographs at these stream gages
                    corresponding to specific storm events can be used to calibrate stream models used
                    in the Lake Erie Watershed.

                    The third USGS stream gage is located on Mill Creek at Erie. This is a partial
                    record station where limited stream flow data are collected systematically over a
                    period of years. Unlike continuous type water sta e recorders, this station has a
                    crest-stage gage which records the peak stage @discharge) occurring between
                    inspections of the gage. Consequently, the usefulness of this data is limiting to
                    calibrating peak discharge rates without regard to the shape of the hydrograph or
                    total runoff volume.

                    Temporary stream gaging stations have been operated from time to time within the
                    watershed. In @eneral, however, they have been operated for very limited time
                    periods, calibration may be irregular and the data collected is not readily available.

                     Therefore, it is anticipated that calibration efforts will employ data collected at the
                     permanent USGS gages.


                     Climate


                     The climate of the watershed is greatly influenced by Lake Erie.              The air
                     temperature during the fall and winter is moderated as air moves over the warmer
                     water in the lake. The slow warming of the lake water surface during the spring
                     delays the start of the growing season, and the warmer water of the lake in the late
                     summer prolongs the normal growing season for this latitude.                   Monthly
                     temperatures measured at Erie range from approximately 24 to 70 degrees
                     Fahrenheit with an annual average of 58 degrees.

                     The amount and character of precipitation are also affected by Lake Erie. The
                     watershed is in the Lake Erie snowbelt, which is created as winter storms moving
                     easterly across the lake drop snow rather than rain into this region. The path of
                     summer thunderstorms is also deflected by higher p@essures due to the cooler
                     temperatures of the lake, resulting in the lake shore region receiving lower summer
                     precipitation than the interior regions of the state. The average annual precipitation
                     in the watershed is approximately 37 inches per year.               Average monthly
                     precipitation volumes measured at Erie range from 1.7 to 4.3 inches per month.

                     Two types of storms that bring heavy rainfall to the watershed are thunderstorms
                     and, to a lesser degree, tropical storms. The June 1972 rains caused by hurricane
                     Agnes were an example of a hurricane that turned into a tropical storm. Summer
                     thunderstorms have resulted in as much as 5.4 inches of rainfall in 24 hours. These
                     thunderstorms are generally localized, thereby confining any resulting flooding to
                     one or two streams.

                     There are three National Oceanographic and Atmospheric Administration
                     precipitation stations located in the vicinity of the Lake Erie Watershed. All three
                     stations are equipped with recording type rain gages capable of measuring and
                     recording hourly rainfall amounts. However, only one, located at Erie is situated
                     within the watershed.

                     Soils


                     The watershed is comprised of two major land areas, each with several predominant
                     soil associations. The first area is the Lake Plain which forms a belt from two to
                     four miles wide along the lake shore. The second is the hilly uplands area along the
                     watershed boundary.

                     The most extensive soil association in the Lake Plain section is the Connotton-
                     Ottawa-Fredon. These are gravelly and sandy soils of the beach ridges and deltas
                     associated with higher levels of the lake in previous ages. Most of the area is
                     occupied by the well-drained Conotton soils.          The Rimer-Wauseon-Berrien
                     association covers a belt close to the lake from the City of Erie to the Ohio line and
                     smaller areas elsewhere in the lake plain. The somewhat poorly to poorly drained
                     Rimer soils make up over two-thirds of the area of this association. The very poorly
                     drained Wauseon soils make up most of the remainder of this area.

                     The Wallington-Birdsall-Williamson-Collamer association is found near the Ohio
                     line and in smaller areas near Harborcreek Township. These are silty and clayey
                     soils with very slow permeability. Ad  .acent to the lake plain in the eastern part of
                     Erie County, on the lower slopes o@ the upland are the Allis-Ellery-Alden soils
                     characterized by slow permeability.
                     Still higher on the slopes is a belt of the Volusia-Mardin association. ne somewhat
                     poorly drained Volusia makes up about 80 percent of the area.

                     Detailed soils information for the Lake Erie Watershed can be obtained from the

                     Land Use

                     Land development in the watershed has centered around the City of Erie. More
                     recently residential and commercial development has occurred in the Erie suburbs.
                     The predominant land use in the watershed remains agriculture, woodland and open
                     space. Residential, commercial and industrial land use is concentrated in the
                     vicinity of the City of Erie and the adjacent urban area as well as the smaller
                     incorporated boroughs within the watershed.


                     Elk Creek Watershed Characteristics



                     General Information


                     The Elk Creek Watershed covers roughly 100 square miles entirely within Erie
                     County. The general location of the watershed is displayed on Plate 1 (introduced
                     previously). The Pennsylvania Department of Environmental Resources' Bulletin
                     No. 5 Dams, Reservoirs and Natural Lakes identifies the following named streams
                     within the watershed:

                                    Lake City Borough                   Waterford Township


                     Topography


                     The topography of the upper reaches of the Elk Creek Watershed consists of rolling
                     hills with a wide, narrowing valley and mild to gentle slopes. The middle and lower
                     reaches can be characterized as rolling hills with a narrow valley and an entrenched
                     creek. Elevations within the watershed range from approximately 1,360 feet in the
                     vicinity of the source to approximately 570 feet at the mouth.


                     Hydrology


                     The source of Elk Creek is in the vicinity of Sharps Corners from where the stream
                     flows in a northwesterly / northerly direction to its mouth on Lake Erie at Lake
                     City. The total length of Elk Creek is approximately 30.4 miles.

                     The Pennsylvania Department of Environmental Resources' Bulletin No. 5 Dams,
                     Reservoirs and Natural Lakes identifies the following dam / reservoir within the
                     watershed:

                                    Fisher Dam, located on a branch of Elk Creek, with a drainage area
                                    of 1.5 square miles.

                     Any potential effects this structure may have on wet weather stream flows and
                     watershed storm water management standards and criteria must be identified during
                     Phase 11 of the Act 167 Storm Water Management Planning process.

                     There are no long term USGS stream gages situated on the streams located in the
                     Elk Creek Watershed. A temporary gaging station is reported to have been
                     operated on Elk Creek at North Girard during 1951. Data collected at this station
                     will reflect stream flow responses from nearly all of the watershed. However, it is
                     unlikely that data from this source will be of significant value in efforts to calibrate
                     the Elk Creek hydrologic model. It is more likely that data collected from one or
                     more of the previously referenced long term, continuously recording gages in the
                     Lake Erie watershed will prove suitable for calibration purposes.

                    Climate


                    The Elk Creek Watershed is located in the same general area as the Lake Erie
                    Watershed. Consequently, the information describing the climate of the area
                    provided previously for the Lake Erie Watershed applies.

                    There are no NOAA weather stations located within the Elk Creek Watershed.
                    However, the previously described station at Erie is sufficiently close to this
                    watershed to permit its use as a source of precipitation information representative
                    of conditions in the Elk Creek Watershed.



                    Soils


                    The 1981 Storm Water Management Plan lists the following soils as predominant in
                    the Elk Creek Watershed:

                          0      Gravelly soils of the outwash terraces (Howard-Phelps-Fredon-
                                 Halsey).
                          E      Deep, medium-textured soils in moderately limy till of the glaciated
                                 upland (Erie-Ellery and Alden-Langford).
                          0      Deep, silty and clayey soils of the gently or moderately sloping
                                 glaciated upland (Plateau-Birdsall).
                          0      Shallow, medium textured soils of the glaciated upland and the lake
                                 plain (Allis-Ellery and Alden).
                          a      Sandy soils of the lake plain (Rimer-Wauseon-Berrien).
                          0      Gravelly and sandy soils on the beach ridges (Conotton-Ottaw-
                                 Fredon).

                    Detailed soils information for the Elk Creek Watershed can be obtained from the
                    county soil surveys published by the U.S. Soil Conservation Service for Erie County.


                    Land Use


                    The predominant land use in the Elk Creek Watershed is agriculture / open space.
                    Residential, commercial and industrial land use is most prevalent in the lower
                    reaches of Elk Creek in the vicinity of Lake City and Girard boroughs.

                          WATERSHEDS


                    Previous Act 167 Planning Efforts


                    In 1981, Erie County prepared a pilot watershed plan for the Lake Erie and Elk
                    Creek Watersheds. The plan, which consists of a series of 14 volumes, was
                    completed using funds provided by the PA Coastal Zone Management Program and
                    the PA Bureau of Dams and Waterways Management. Volume 1 is a technical

                    document written for the individual interested in the more detailed aspects of the
                    plan. The remaining volumes in the series represent applications of the plan to
                    specific features of the various subwatersheds within the Lake Erie and Elk Creek
                    Watersheds.

                    Only a small portion of the Plan was implemented due to a lack of interest on the
                    local level. However, it should be noted that North East Borough and North East
                    Township have adopted Storm Water Management ordinances. To date, these are
                    the only two municipalities in Erie County which have adopted Storm Water
                    Management Ordinances in accordance with a State approved Storm Water
                    Management Plan. In addition, Summit Township and Millcreek Township adopted
                    Storm Water Management Ordinances in 1990 under the authority of the
                    Pennsylvania Municipalities Planning Code.

                    The 1981 Storm Water Management Plan for the Lake Erie and Elk Creek
                    Watersheds was performed as a pilot plan in the early stages of the Act 167 planning
                    process. Unfortunately, planning and analysis methods and the basic approaches to
                    watershed stormwater management have diverged greatly from those used in the
                    1981 plan. This coupled with the age of the document, severely reduces its utility.
                    While some information contained in the plan will be of use in the preparation of a
                    new Phase 11 plan, the existence of the document will have little impact upon the
                    level of effort and cost of preparing the updated plan for these watersheds.


                    Combined Sewer System Investigations

                    The City of Erie had entered into a consent decree with the Penns7lvania
                    Department of Environmental Resources which includes requirements or the
                    completion of investigations into the sources of and methods for reducing pollution
                    entering the Mill Creek Tube (the lower of reaches of Mill Creek) and Presque Isle
                    Bay from other sources. These investigations are expected to result in the collection
                    of data and the assembly of hydrologic and water quality model(s) which may be of
                    use during the preparation of the Act 167 Watershed Storm Water Management
                    Plan(s) for the Lake Erie and Elk Creek Watersheds. The investigations are in the
                    early stages and are scheduled to be completed over a period spanning two to three
                    years. Consequently, the exact nature and potential utility of this information
                    relative to the Act 167 planning effort cannot be defined at present. However, these
                    investigations are recognized and the review, assessment and possible use of
                    information developed during their completion will be an element of the Phase 11
                    planning effort for the Lake Erie Watershed.


                    Assessment of Providing Selected Services Through Alternative Intergovernmental
                    Arrangements in the Erie Metropolitan Area


                    The Erie County Planning Department and the Pennsylvania Economy League, Inc.
                    are involved in a study to explore the feasibility and desirability of providing
                    selected municipal services through various types of intergovernmental
                    arrangements.     The area of the investigation is limited to the following
                    municipalities:



                                                                                    TreCtumAerE-gineers

                    These municipalities are all located in the Lake Erie Watershed and Summit and
                    Fairview townships are also located in the Elk Creek Watershed.

                    Phases I and 11 of the study have been completed and Phase III is commencing.
                    One of the areas of service investigated is storm water management. The study
                    investigated several mechanisms for sharing municipal resources in the area of
                    storm water management. The Intergovernmental Task Force has made the
                    following recommendations relative to storm water management issues:

                            0      incorporate the creation of a regional storm water management
                                   authority into the discussions of the creation of a regional sewer
                                   authority, and
                            a      through the County, include in all requests for proposals that might be
                                   solicited by individual jurisdictions for technical studies on storm
                                   water management, an acknowledgement of the interest of the Erie
                                   area to eventually create a storm water management regional
                                   authority.

                    In consideration of these recommendations, the Phase 11 Act 167 Watershed Storm
                    Water Management Plan(s) for the Lake Erie and Elk Creek Watersheds will
                    include an evaluation of the formation and use of a regional storm water
                    management authority implementing watershed storm water management in the
                    watersheds.


                    Summary


                    Given the previously described watershed characteristics and the prior stormwater
                    management planning efforts and ongoing and planned studies described above, the
                    watershed planning process for this study area must be fitted to the watershed
                    characteristics, as well as the resources (technical, political and economic) of this
                    area. This section of the Phase I - Scope of Study presents the concept and
                    approach that has been developed to fully meet these requirements, as well as the
                    specific requirements of Act 167, for this watershed storm water management
                    project.


                    Benerits of the Plan(s)


                    The purpose and benefit of the study and implementation plan is to provide all of
                    the municipalities in the watershed (in compliance with the requirements of
                    Pennsylvania Act 167) with an accurate and consistent implementation strategy and
                    procedures for comprehensive storm water management. Currently, not all of the


                                                                                     TieChesterEngineers

                     watershed municipalities enforce storm water management regulations and, for
                     those that do, actual enforcement criteria vary. Given the nature of storm runoff
                     and its impacts, as described earlier in this document, a critical objective of sound
                     storm water management planning is to provide for consistency of implementation
                     requirements throughout the watershed. Therefore, the primary objective of the
                     technical study and planning process is to develop a technical        and institutional
                     support document to encourage and/or support the consistency of regulations for
                     implementation based on watershed-wide consideration.
                     The currently accepted watershed planning approach (technical and institutional)
                     recommended by the DEPARTMENT also provides the municipalities of a
                     watershed (in addition to the County) with a considerable amount of usable
                     technical information, such as a detailed watershed runoff simulation model, that
                     can be used for numerous other associated purposes for participating municipalities.
                     Therefore, as a result of developing the primary product of the watershed planning
                     effort (i.e. the implementation plan for local regulation of storm water runorf
                     impacts), the participating municipalities, as well as the County, will realize benefits
                     and/or products that are usable for other planning and engineering purposes.
                     For example, land use updates and environmental data management are functions
                     that are necessary for effective planning in a watershed. The technical approach
                     being proposed for the Lake Erie and Elk Creek Watersheds Act 167 planning
                     project will provide unique environmental database management benefits for not
                     only the County, but also for municipal use. Another example of the associated
                     benefits of an Act 167 watershed plan relates to basic public works and/or
                     engineering functions, primarily at the municipal level.
                     In addition, technical support information, provided as a part of the watershed
                     modeling effort, can be used by public works officials for bridge replacement and

                     cost-effectively developed using the calibrated watershed model. Therefore, the
                     benefits of the watershed planning process are wide-ranging, even beyond the
                     important function of developing comprehensive storm water management
                     strategies and ordinance provisions.


                     Approach for the Development of the Watershed Plan(s)

                     In order to implement watershed-wide comprehensive planning for and
                     management of storm water runoff, it was necessary to take a very close look at all
                     portions of the watersheds for this Phase I study. Since the Act itself is very
                     dependent on municipal coordination to provide for the total planning and
                     management of storm water throughout the watersheds, it is necessary to get each
                     municipality in the watersheds involved in the planning process.
                     In order to identify the storm water problem areas and to initiate municipal level
                     involvement in the overall development of the PLAN, a Watershed Plan Advisory
                     Committee and a questionnaire strategy is incorporated into the Phase I work
                     approach for the watershed. The Watershed Plan Advisory Committee (WPAQ
                     was formed by the COUNTY and consists of the required municipal officials and
                     interested parties. The County held two VVTAC meetings during the Phase I
                     planning process. The following is the WPAC membership list.

                         The questionnaire is designed to solicit               input from each municipality, relative to
                         very specific problems in the watershed,               as well as for the needs they may see for
                         storm water management in their particular area. T'he questionnaire will be
                         distributed, along with a summary of the purpose of Act 167 which includes an
                         emphasis on Act 167 goals as they relate to this watershed. (An example of the

                         strategy for the Lake Erie and Elk Creek Watersheds is the interest by the

                         A total of 45 storm water problems were reported by 11 of the municipalities which
                         returned the municipal questionnaires. Reported causes of the problems included
                         excessive runoff, undersized drainage systems, stream obstructions and a lack of
                         maintenance of drainage ways. Five of the reported problems occur nearly every
                         time it rains, 30 of the problems occur roughly between 1 and 10 times per year and
                         the remainder of the problems occur infrequently in response to unusually large
                         storm events.

                         The 1981 Plan contained a tabulation of identified problems which existed at the
                         time the plan was prepared. This information is provided in Table 2 as a
                         supplement to the information provided via the municipal questionnaires.

                         ne pilot plan identified a total of 42 problems in 8 of the 20 municipalities in the
                         watershed (40%). The predominant reported causes of these problems was flooding
                         at culverts or bridges which is indicative of excessive runoff and/or undersized
                         facilities. The occurrence of ice jams was also a frequently reported cause of
                         stormwater drainage problems.

                        The overall evaluation of the questionnaire illustrates a very significant point. The
                        results indicate that even though there are localized storm water problems, their
                        number and frequency of occurrence appears to be relatively low. Therefore, the
                        Lake Erie watershed will realize significant benefits during the planning period
                        because of the Act 167 Plan, since storm water management will be initiated before
                        there is a large number of major existing problems. Because there remains much
                        room for growth and development in the Lake Erie Watershed (and because this
                        growth is being projected with some de           $ree of confidence) the Act 167 Watershed
                        Storm Water Management Plan for this area may be an excellent example of a
                        storm water impact "prevention" plan -- as is the true intent of Act 167.
                        As additional areas of the watershed will experience growth, the technical support
                        basis for the standards and criteria developed in this initial planning project can be
                        easily modified without invalidating the overall plan. The detailed description of
                        the technical modeling activities, presented in the work step descriptions in the next
                        section of this document, will provide more insight into the specific modeling
                        approach to be used to accomplish this objective.

                        Identified Problems in the Elk Creek Watershed

                        A summary of problems reported in the questionnaires for the Elk Creek
                        Watershed is provided in Table 3. Twenty stormwater drainage problems were
                        identified in seven of the municipalities which responded to the questionnaire. The

                         rodominan, @eported cause, of the problems was excessive runoff, although
                                   t ly
                        inadequa e       sized drainage systems obstructions and a lack of maintenance of
                        drainage ways were also reported. Four of the problems were reported to occur
                        during nearly every significant rainfall event. Eight of the, problems occur at a
                        frequency of 1 to 10 times per year, while the remainder of the problems arise only
                        during unusually large precipitation events.
                        The 1981 Plan contained a tabulation of identified problems which existed at the
                        time the plan was prepared. This information is provided in Table 4 as a
                        supplement to the information provided via the municipal questionnaires.

                        The pilot plan identified 41 problems in 9 of the 12 municipalities in the watershed
                        (75%). The most frequently reported type of problem was flooding at culverts or
                        bri4es. This is indicative of excessive runoff and/or inadequately sized drainage
                        facilities.

                        The overall evaluation of the Ruestionnaires and pilot plan illustrates a very
                        significant point. The results indicate that even though there are localized storm
                        water problems, their number and frequency of occurrence appears to be relatively
                        low. Therefore, the Elk Creek watershed will realize significant benefits during the
                        planning period because of the Act 167 Plan, since storm water management will be
                        initiated before there is a large number of major existing problems. Because there
                        remains much room for growth and development in the Elk Creek Watershed the
                        Act 167 Watershed Storm Water Management Plan for this area may be an
                        excellent example of a storm water impact "prevention" plan -- as is the true intent
                        of Act 167.

                     As additional areas of the watershed will experience growth, the technical support
                     basis for the standards and criteria developed in this initial planning project can be
                     easily modified without invalidating the overall plan. The detailed description of
                     the technical modeling activities, presented in the work step descriptions in the next
                     section of this document, will provide more insight into the specific modeling
                     approach to be used to accomplish this objective.

                     IV. PLAN PREPARATION STRATEGY

                     The PLAN(S) will contain, at a minimum, the following items:

                     1.     a survey of existing runoff characteristics in small as well as large storms,
                            including the impact of soils, slopes, vegetation and existing development;

                     2.     a survey of existing significant obstructions and their capacities;

                     3.     an assessment of projected and alternative land development patterns in the
                            watershed, and the potential impact of runoff quantity, velocity and quality;
                     4.     an analysis of present and projected development in flood hazard areas, and
                            its sensitivity to damages from future flooding or increased runoff;

                     5.     a survey of existing drainage problems and proposed solutions;

                     6.     a review of existing and proposed storm water collection systems and their
                            impacts;

                     7.     an assessment of alternative runoff control techniques and their efficiency in
                            the particular watershed;

                     8.     an identification of existing and proposed State, Federal and local flood
                            control projects located in the watershed and their design capacities;

                     9.     a designation of those areas to be served by storm water collection and
                            control facilities within a ten year period, an estimate of the design capacity
                            and costs of such facilities, a schedule and proposed methods of financing the
                            development, construction and operation of such facilities, and an
                            identification of the existing or proposed institutional arrangements to
                            implement and operate the facilities;
                     10.    an identification of flood plains within the watershed;
                     11.    criteria and standards for the control of storm water runoff from existing and
                            new development which are necessary to minimize dangers to property and
                            life and carry out the purposes of this act;
                     12.    priorities for implementation of action within each plan;
                     13.    provisions for periodically reviewing, revising and updating the plan;
                     14.    provisions as are reasonably necessary to manage storm water such that
                            development or activities in each municipality within the watershed do not


                                                                                     Rie@@Jineers

                              data summary will be prepared that will identify and@or catalogue the
                              collected data.

                       Task 4 - Institutional Data Preparation

                       This task involves the detailed evaluation of the municipal ordinances
                       (gathered during the Task 3 data collection efforts) in order to prepare a
                       municipal ordinance comparison matrix. This matrix is intended to display, for
                       both the actual preparation of the implementation plan and also for the
                       municipal education process, the current storm water management provisions'
                       in the various municipal ordinances for all watershed municipalities. The
                       objective of the matrix is to easily and effectively see the similarities and
                       differences, as well as the consistency/inconsistency, between the various
                       municipal ordinances in the watershed. The matrix will be used, in the
                       institutional analysis task (Task 9) to develop ordinance provision
                       recommendations for the various municipalities that are based on the storm
                       water management standards and criteria (identified in the technical plan) for
                       the watershed. This matrix then serves the long-term implementation efforts
                       by providing a convenient reference for the COUNTY to evaluate the
                       individual changes to the various municipal ordinances that will be required as

                                                                                    lbl@_@@ireers

                                     the consultant in the preparation of the municipal ordinance
                                     matrix.

                                     Consultant - responsible for the preparation of the municipal
                                     ordinance provision matrix. Also responsible for the review of
                                     the completed municipal ordinance provisions matrix for
                                     consistency with the needs of the Task 9 institutional analysis
                                     and implementation plan development efforts.

                              Anticipated Task Product

                              The product of this task will be a completed matrix of storm water
                              management ordinance provisions for the watershed municipalities
                              which identify the current status of ordinance provisions as they relate
                              to storm water management.

                       Task 5 - Data Preparation for Technical Analysis

                       This task involves the engineering work necessary to transform the raw
                       information collected in Task 3 into a form/format that can be directly used
                       for the later technical tasks in the overall planning program. A primary effort
                       to be conducted as a part of this task is the preparation of the "land
                       characteristics" information for modeling purposes. That is, this task effort
                       includes the necessary map preparation efforts to develop land use, soils, and
                       slope maps for modeling.

                       Data collection and preparation will be coordinated with the County's on-
                       going GIS development program. Data acquisition and archival methods will
                       be selected and completed so as to produce a geographic data set which is
                       compatible with the County's system. Prior to the collection of data, the data
                       set contained in the County's system will be reviewed to identify and access
                       relevant information and avoid duplication of effort. At the present time, it is
                       anticipated that the map preparation effort will involve the following:
                              Land Use/Land Cover Information - land use/land cover information
                              will be derived from Landsat Thematic Mapper, National High
                              Altitude Program (NHAP) imagery. Land use/land cover throughout
                              the watershed will be classified into categories corresponding to those
                              for which the U. S. Soil Conservation Service has developed
                              rainfall/runoff relationships. The classified data will be processed
                              using Arc/INFOtm and ERDAS tm Geographic Information Systems
                              (GIS) analysis packages.      The various land use/land cover types
                              existing throughout the watershed will be presented on a basemap.
                              Future Land Use Conditions - the existing land development conditions
                              (classified imagery) will be updated to also separately illustrate those
                              areas that are projected for development within a 10-year planning
                              period. These future land development areas will be separately and

                               conditions modeling and planning.
                               Soils Information - the County Soils Survey maps will be modified
                               and/or prepared to illustrate SCS hydrologic soils groups instead of
                               individual soil types. These data will be digitized and incorporated into
                               the GIS database to facilitate the cross referencing of land cover/soil
                               group intersections required to determine rainfall/runoff relationships
                               based upon U. S. Soil Conservation procedures.

                               Slope Information - U. S. Geological Survey Digital Elevation Models
                               (DEM) for the required 7.5 minute quadrangles will be obtained and
                               incorporated into the Lake Erie and Elk Creek GIS database. This
                               data will be used to assign slope category information to subareas for
                               which detailed modeling will be completed.

                        Delineation of Subwatersheds

                        The watershed and subwatersheds will be delineated by the consultant on a
                        base map at a scale of 1 inch equals 2,000 feet. Subwatersheds will be
                        established based on the office data and results of the field reconnaissance
                        task. This breakdown of the watershed by major tributary drainage courses
                        and points-of-interest will be the basis for the hydrologic and hydraulic
                        analysis.

                        The subwatersheds will be further delineated to subareas based on the
                        following:

                                      the location of existing problems, as identified by local officials
                                      in the municipal survey, during the field reconnaissance, or from
                                      data previously compiled in any previous studies such as water
                                      quality monitoring programs,
                                      the location of major obstructions (primarily bridges), highway
                                      culverts, or storm water control facilities,
                                      confluence points of tributaries, as deemed appropriate based
                                      on engineering judgement and good modeling practice, and
                                      other points of interest, such as stream gaging or water quality
                                      monitoring stations, locations of water quality concerns, or
                                      outfall sections downstream of existing developments or where
                                      development could be anticipated to occur.
                        This task will also include the mapping of relevant watershed planning
                        information onto a final watershed map. This mapped information will be
                        selected from the data identified and collected in the Task 3 effort, including:
                                      floodplain areas - which will involve the indication on the
                                      mapping of those areas for which detailed flood insurance
                                      studies are available, as well as an indication of those areas
                                      and/or sections of streams for which such detailed information
                                      is not currently available.

                       Hydrologic models currently in use include, but are not limited to, the Penn
                       State Runoff Model PSRM, HEC-1 (Corps of Engineers), TR-20 (SCS) and
                       SWMM.

                       The selected model will be applicable to the size, land use and geological
                       characteristics of the watershed and will be able to accurately and reliably
                       simulate the runoff characteristics for design storms of various frequencies and
                       durations to produce routable hydrographs that can easily be combined.
                       Planned investigations of the Mill Creek Tube will include the development of
                       hydrologic / water quality model(s). During the selection of the model for use
                       in the preparation of the Uke Erie Watershed Plan, consideration will be
                       @iven to the potential for coordinating the model used with the model(s) used
                       in the Mill Creek Tube study. However, the primary factors to be used in
                       model selection will be usefulness in the development of the required
                       standards and criteria and the economics of the use of the model in the
                       preparation of watershed plans throughout Erie County.

                       characteristics for six selected frequency design storms (i.e., the mean annual,
                       5-, 10-, 25-, 50-, and 100-year storm events with various durations) and two
                       land use scenarios (existing and future conditions). This task also includes the
                       necessary efforts to calibrate and verify the model for the Lake Erie and Elk
                       Creek Watersheds. This calibration effort will utilize any available prior
                       watershed hydrologic results (for example, completed by the U.S. Army Corps
                       of Engineers) to verify the predicted response to rainfall events.
                       It is anticipated that watershed specific concurrent rainfall and stream flow
                       records will be available for portions of the Lake Erie and Elk Creek
                       Watersheds. These data will be used to "test" the accuracy of the model by
                       making model runs. In the event that these data prove to be unusable or
                       unavailable, data from neighboring similar watersheds will be used to assess
                       the calibration of the Lake Erie and Elk Creek Watersheds model. If for
                       some reason neither of these approaches proves to be feasible, a regression

                        type approach (such as using PennDOTs PSU IV method) will be used to
                        generally corroborate the model for the watershed. The calibration effort will
                        result in the fine tuning of the watershed modeling input data parameters so
                        that the required design storm modeling efforts can be initiated with
                        confidence.

                        Subsequent to calibration of the model, the consultant will run the model for
                        the mean annual, as well as the 5-, 10-, 25-, 50- and 100-year storm events with
                        various duration (which depend on time of concentrations). The anticipated
                        evaluation of the results will consider the peak flow rates, as well as flood
                        conditions in the stream for the various storms. This evaluation will be
                        jud&mental based on detailed HEC-11 analysis of the creek and tributaries if
                        available. If HEC-11 results are not available, no effort will be made to
                        perform a HEC-11 analysis and the required evaluation will be solely
                        judgmental. Existing capacities of the obstructions on the stream and other
                        downstream locations will also be used to identify storm runoff problem areas
                        for use in developing the technical standards and criteria for storm water
                        management in Task 8.

                        This analysis will also involve determination of the required design storm. The
                        selection of a watershed design storm, for use in the standards and criteria, will
                        be based on an evaluation of the watershed hydrologic response for the six
                        design storms to be evaluated. Downstream impacts for the various design
                        storms will be evaluated to determine what level of control (e.g., 100-year
                        versus 10-year) will provide cost-effective management of projected
                        downstream areas. For example, it would not be reasonable to select the 100-
                        year storm for the standards and criteria if current (or anticipated) floodplain
                        management and/or zoning requirements in the municipalities would address
                        100-year runoff impacts in flooqplain areas. The selected design storm will
                        also consider the results of the institutional analysis of current procedures in
                        the municipalities.

                        The two land use scenarios to be evaluated for this Act 167 watershed plan
                        include: (1) existing land use, as identified from the most current mapping for
                        the watershed with modifications based upon municipal input concerning
                        recent land development projects; and (2) future land use that will be
                        projected to occur within an approximate planning time frame of ten years.
                        Unless the combined sewer and storm sewer discharge investigations planned
                        to be performed by the City of Erie warrant a different approach, the
                        particular methodology to be used is based on commonly accepted procedures
                        6- storm water pollution (or "Nonpoint Source" pollution) analysis. These
                        procedures are based on the identification of "pollution wash off potential" for
                        the watershed given the types and extent of land use characteristics. That is,
                        given the land cover conditions are necessary data for modeling, these data
                        can also be used to identify the pollution wash off potential for the watershed.
                        "Best Management Practices" or BMP's will be recommended based on the
                        results of this preliminary assessment for those areas found to be of significant
                        impact potential. These recommendations will be included as part of the final
                        plan contents. Any relevant recommendations produced by the City of Erie's
                        combined sewer and separate storm sewer discharge investigations will be
                        included in the Plan as consistent with the intent of Act 167.

                       These recommendations will include storm water quality management
                       components for the technical Standards and Criteria. These water quality

                              The product of this task will be the charts, tables and graphs developed
                              to present the modeling results, and the technical interpretation of the

                       Task 7A - Expanded Non-Point Source Pollution Modelin

                       Task 7, as described previously, represents a basic assessment of non-point
                       source pollution potential and a general listing of recognized best
                       management practices. This Task 7A will consist of a more extensive analysis
                       of non-point source pollution potentials within the watersheds under current
                       and future land use conditions. Task 7A will also generate estimates of the
                       potential impact of the implementation of best management practices on non-
                       point source pollutant loadings on Lake Erie. This will support a rational
                       assessment of the importance of implementing such practices and their effects.
                       Unless the progress, results and findings of on-going non-point source
                       pollution investigations being conducted by the City of Erie and the Erie
                       County Conservation District warrant a different approach, non-point source
                       pollution modeling will be accomplished using the United States
                       Environmental Protection Agency's SWMM model. The SWMM model will
                       be used in its continuous simulation mode to produce estimates of             al"
                       annual pollutant loads discharged to Lake Erie from the Lake Erie an(170p,,IcElk
                       Creek watersheds under three conditions: 1) existing land use, 2) future land
                       use with no non-point source pollution controls and 3) future land use with
                       best practical management practices applied to new land development.

                       Task 7A will include the following principal work elements:
                                     Conversion of the watershed geometric and physical features
                                     dataset developed and used in Tasks 5, 6 and 7 for use in the
                                     SWMM model.

                              to present the modeling results, and the technical interpretation of the
                              modeling results.

                       Task 8 Develop Technical Standards and Criteria
                       This task will involve the detailed evaluation of modeling results to perform a
                       problem identification analysis (i.e., a "cause and elffect" analysis). This
                       analysis will concentrate on identifying the downstream storm runoff impacts
                       of projected future land development projects. T'his evaluation will obviously
                       consider both the increase in current downstream storm runoff problems, as
                       well as new downstream runoff problems.

                       This work step also consists of performing a technical evaluation of the
                       hydrologic analysis for existing and ultimate land use conditions and
                       recommending standards and criteria to regulate development activity which
                       i
                           acts storm water runoff. This task also involves performing a release rate
                       (morpother similar) analysis and a preliminary distributed storage analysis, and
                       developing criteria and standards for proposer control for storm water for new
                       developments. Recommended standards and criteria will accommodate each
                       land development activity, which may range from small lot sizes such as single
                       family dwellings to large commercial or institutional complexes such as
                       shopping malls, schools, hospitals, industrial parks, landfil    ,Is, etc.   The
                       standards and criteria will provide for the application of management
                       practices for the implementation of storm water control measures.

                       e.      specifications for construction and maintenance of storm water systems
                               (if applicable);

                       f.      safety requirements for storm water systems during and after
                               construction;

                       9.      water quality management steps and/or actions which are applicable to
                               this watershed. An evaluation will be completed which will project
                               potential storm runoff quality impacts and recommendations will be
                               identified for proper management of these potential storm quality
                               impacts.
                       T@e recommendations will be presented in layman's language, keeping in
                       mind that they are directed toward the local municipalities and are to address
                       solutions to storm water management needs and will be read and interpreted
                       bX technical as well as non-technical people. The technical standards and
                       criteria developed as a part of this task will be watershed-wide in their
                       interpretation and/or application.

                        Task 9 - Institutional Analysis

                        This task involves the detailed review of ordinances for each individual
                        municipality in the watersheds using the ordinance provisions matrix
                        completed as a part of Task 4. The evaluation of the municipal ordinance
                        matrix will be conducted using the results of Task 8 (i.e. the development of
                        the technical standards and criteria). Essentially, this task effort will involve
                        the identification of the necessary ordinance provisions for each watershed
                        municipality that will be required to be instituted in order to effectively
                        comply with the technical standards and criteria developed in Task 8.

                        In addition, this review and analysis will include the identification of
                        appropriate legal and/or financial alternatives that can be used, under the
                        proposed PLAN, for storm water management. Also included as a part of this
                        task will be the evaluation of intermunicipal arrangements for watershed level
                        storm water management, including those that would be necessary to
                        implement a regional storm water management concept (e.g. the distributed
                        storage concept).

                        The evaluation for this task will include the preparation of ordinance
                        provisions for single or multi-purpose ordinances, as selected by the County
                        with appropriate municipal involvement, in order to again effectively
                        implement the technical standards and criteria for storm water management in
                        this watershed.

                        Task 10 - Plan Report Preparation
                        The consultant with COUNTY support will compile various components of
                        the PLAN. Each component of each previous task will be directly included, or
                        at least referred to in the plan. In this way the plan shall contain such
                        provisions as are reasonably necessary to manage storm water such that storm
                        runoff from development or activities in each municipality within the
                        watersheds shall not adversely affect health, safety and property in other
                        municipalities within the watersheds and in basins to which the watersheds are
                        tributary. In addition, the plan shall consider and be consistent with other
                        existing municipal, county, regional and state envirom-nental and land use
                        plans.  The PLAN shall include the following:
                                A description of the hydrologic characteristics of the watershed, the
                                present and future land uses and their impacts on runoff, storm water
                                collection systems and their impacts on runoff, the available runoff
                                control techniques and their efficiencies in the watershed, a list of
                                signification obstructions and a justification of their classification and
                                available floodplain information. The available floodplain information
                                will either be included in the plan or their sources referenced;

                                Based upon the results of the watershed modeling, the technical
                                evaluation resulting in the criteria and standards governing the use of
                                storm water management controls throughout the watersheds. An
                                important aspect of the technical components of the plan will be the
                                delineation of areas which should (and areas that should not) use storm
                                water detention to reduce peak flows. This determination will be made
                                based upon an evaluation of subarea contributions to peak flows at the
                                identified critical drainage points throughout the entire watersheds.
                                Each of the storm water management alternatives as discussed earlier
                                will be incorporated in the plan as appropriate, based upon the
                                modeling results. Peak discharge tables will be compiled for the'critical
                                drainage points from the computer runs involved in the modeling
                                effort;

                                The tables for the rainfall depths for various frequency durations which
                                are computed as part of the hydrologic modeling;

                                Recommendations for solutions to the existing drainage problems
                                (since the Act 167 is not intended to solve existing problems, but to
                                prevent their aggravation and also prevent other future problems, these
                                recommendations for solutions to existing problems that are found to
                                be relevant to the PLAN will only be conceptual in nature indicating
                                the type of approach needed and intermunicipal cooperation issues);
                                Recommendations for new drainage facilities to prevent future
                                problems due to new development, and a discussion regarding
                                intermunicipal arrangements for funding the projects will also be
                                discussed.

                                A model storm water management ordinance, a list of priorities for
                                implementation and a list of recommendations. Recommended actions

                      Plan Update
                      As a part of the implementation strategy for the PLAN, specific steps and/or
                      procedures will be established for pursuing and completing the necessary
                      updates of the PLAN as required by Act 167. Specific circumstances will be
                      identified and described in the PLAN document that will "trigger" a decision to
                      update the plan, and this will certainly be the case for the required 5-year
                      update. For example, land development circumstances (such as major changes
                      in the tyj)e and/or amount of proposed land development, and certainly in
                      excess ot that which was assumed tor the preparation of the original PLAN)
                      will be identified as reasons for pursuing an update of the PLAN prior to the
                      required 5-year time frame identified in Act 167.

                      Plan Adoption
                      The COUNTY will transmit the completed PLAN to the official planning
                      agency and governing body of each involved municipality, each member of the
                      WPAC and the DEPARTMENT by official correspondence. The involved
                      municipalities, WPAC and DEPARTMENT will then review the PLAN.
                      Their review will include an evaluation of the PLAN'S consistency with other
                      plans and programs affecting the watershed. The review and comments will be
                      submitted to the COUNTY by official correspondence. The review comments
                      will be received, tabulated, and responded appropriately and the PLAN will be
                      revised accordingly.
                      Prior to PLAN adoption, a final meeting will be held with municipalities; to
                      identify specific ordinance changes and method(s) of incorporation of the
                      standards and criteria into municipalities' existing ordinance framework. In
                      addition, the meeting(s) can also serve to provide clarification of any
                      @emaming questions or concerns that municipalities may have concerning the
                      implementation of the PLAN for any municipality.
                      The COUNTY will hold a public hearing concerning the PLAN. A notice for
                      the public hearing will be published at least two weeks before the hearing
                      date. The public hearing notice will contain a brief summary of the principal
                      pro sions of the PLAN and a reference to the places within each affected
                      municipality where copies of the PLAN may be examined or purchased at cost.
                      The comments received at the public hearing will be reviewed by the
                      COUNTY and appropriate modifications in the PLAN will be made if
                      applicable.

                      The PLAN will be voted as a resolution by Erie County Council for the
                      purpose of adoption. The resolution will have to be carried by an affirmative


                                                                                  TheChesterEngineers

                       to comprise the PLAN. This action will then be recorded on the adopted
                       PLAN.

                       The County will then submit to the DEPARTMENT a letter of transmittal,
                       and three copies each of the adopted PLAN, the review by the official
                       planning agency and governing body pf each municipality, County Planning

                       adoption of the PLAN by the COUNTY (Section 8 (b) of Act 167). The letter
                       of transmittal will state that the COUNTY had complied with all procedures
                       outlined in Act 167 and will request DEPARTMENT to approve the adopted
                       PLAN.

                                     COUNTY -- primary responsibility for the adoption activities
                                     described above, and will also assist the consultant concerning
                                     establishment of priorities for implementation of actions
                                     identified in the PLAN and update schedule.

                                     Consultant -- responsible for providing support and guidance to
                                     COUNTY during PLAN adoption process and will establish
                                     priorities for implementation of actions identified in the PLAN

                              Anticipated Task Product

                       The product of this task will include the official documentation regarding the
                       PLAN adoption and implementation process, including the necessary
                       documentation from the COUNTY certifying the adoption of the PLAN, and
                       the adopted PLAN together with a listing of priorities for implementation and
                       a schedule for plan updating.

                    V.     LEVEL OF EFFORT AND COST ESTIMATE

                    The previous eleven (11) work steps were further broken down into subtasks to
                    analyze the required level of effort, both by the County and the consultant to
                    complete each work step. The estimated staff time for each project team member
                    for each subtask are presented in this section. The cost estimates resented in
                    Tables 5, 6 and 7 (contained on pages 42 through 47) reflect the specific work step
                    descriptions presented in Section IV, including the use of the particular procedures
                    and methodologies that are presented.

                    The consultant will provide services and guidance to the County for all the work
                    tasks at a level of staff involvement consistent with Tables 5, 6 and 7. These tables
                    list the breakdown of the estimated level of effort for the work program described
                    herein, based on and including the items identified in the task descriptions.
                    The cost estimates summarized in Tables 5 and 6 represent estimates associated
                    with preparing the Lake Erie (Table 5) and Elk Creek (Table 6) Plans separately
                    and at different times.      The estimates presented in Table 7 anticipate the

                     preparation of a single Plan encompassing both the Lake Erie and Elk Creek
                     Watershed.

                     Summaries of the estimated costs to complete the Lake Erie and Elk Creek
                     Watershed Storm Water Management Plan(s) allocated between the consultant and
                     the County are presented in Tables 8, 9 and 10. Table 8 (Lake Erie) and Table 9
                     (Elk Creek) represent the separate completion of Plans for the two watersheds and
                     summarize the information presented previously in Tables 5 and 6, respectively.
                     Table 10 summarizes the costs associated with preparing a single plan for the two
                     watersheds (as detailed in Table 7). A further breakdown of the cost estimates is
                     provided in Appendix C.

                     As the data presented in Tables 7 through 10 indicate, it would be much more
                     economical to complete the watershed planning for the Lake Erie and Elk Creek
                     Watersheds simultaneously. The total cost for completing the Phase II planning for
                     the two watersheds individually at different times is $607,242. The estimated cost
                     for completing the necessary planning for both watersheds simultaneously @n a single
                     plan document is $408,318. This large cost differential is attributable primarily to
                     the avoidance of a duplication of effort.

                     VI. PROPOSED PLAN DEVELOPMENT SCHEDULE


                     A schedule@ has been developed for completing the work program described herein.
                     It is felt that the developed time frame for this project is sufficient for all the
                     necessary contacts and follow-up correspondence, for each of the municipalities and
                     for the applicable tasks. The proposed schedule represents the time frame required
                     to complete a single Plan, whether or not it encompasses a single designated
                     watershed or both of the watersheds combined. In the event that the Plans are
                     prepared for each of the two watersheds separately, two 36 month schedules would
                     be followed separated in time by the differences in the dates at which the projects
                     were initiated.

                     The proposed work schedule is presented in Figure 2 on page 48.

               Call to Order


               Mr. Skellie called the meeting to order at 7:00 P.M.

               History of Storm Water Manacement in Erie County


               Mr. Skellie distributed a hand-out on the storm water management
               planning efforts which have been undertaken to-date in Erie County.
               He then gave a brief overview of the following items which are
               included within the hand-out:


               - Development of the 1981 Storm Water Management Plan for the Lake
                  Erie and Elk Creek Watershed areas.


               -  Adoption of four (4) municipal storm water management ordinances.












                - Identification of the nine (9) watershed areas in Erie County.

                - The   County's    tentative schedule- for storm water management
                  planning over the next five (5) years.

                A  copy of this hand-out is incorporated into the minutes as
                Attachment A.


                Mr. Skellie explained that the County of Erie is currently in the
                process of updating the 1981 Storm Water Management Plan for the Lake
                Erie and Elk Creek Watershed areas. The first step in this process
                is the development of a Phase I Scope of Study in order to determine
                the costs, schedule, and the level of effort required by the County
                to complete a Phase II Storm Water Management Plan. The County has
                hired The Chester Engineers to prepare the Scope of Study. The
                deadline for completing the Phase I project effort is June 30, 1991.

                As part of the Phase I planning process, the County has established a
                Watershed Plan Advisory Committee (WPAC). The purpose of the WPAC is
                to provide a forum for the presentation and discussion of local storm
                water management concerns.     The WPAC will remain active throughout
                Phases I and II.      Mr. Skellie also noted that the Phase II project
                effort will be much more expensive than Phase I.

                Overview of the Act 167 Storm Water Management Planning Process

                Mr. Skellie then turned the meeting over to Mr. John Maslanik of The
                Chester Engineers. Mr. Maslanik gave a slide presentation on the Act
                167 Storm Water Management Planning Process.         The following are
                highlights from Mr. Maslanik's presentation:

                1)   Based on past experience, the overall planning process for a
                     particular watershed (Phases I and II) can take 4 to 5 years to
                     complete.

                2)   Flooding caused as a result of Hurricane Agnes helped trigger
                     the passage of the Flood Plain Management Act (Act 166 of 1978)
                     and   the    Storm Water Management Act (Act 167 of 1978).
                     Virtually all municipalities in the State have          now adopted
                     Flood   Plain    Management   Regulations in order      to control
                     development in flood hazard zones. The State is         now pushing
                     for the development of local Storm Water Management     Regulations
                     which will require land developers to control storm     water which
                     originates from their development site in order to prevent
                     damage to downstream properties and avoid expanding flood
                     hazard areas.


                3)   Existing land developments generally are not affected by the
                     requirements of Act 167.

                4)   Act 167 planning procedures:

                        Watersheds within the state are designated for future study.

                                                    2 -











                      - Watersheds are sequentially selected for preparation of
                        storm water management plans.
                      - Completion of a Phase I Scope of Study.
                        Completion of a Phase II Storm Water Management Plan.
                      - County adopts Storm Water Management Plan.
                      - Municipalities in the watershed are required to adopt storm
                        water management ordinances within 6 months of the County's
                        adoption of the plan.
                      - Municipal     administration   of    storm   water    management
                        ordinances.
                      - Periodic updates of the Storm Water Management Plan (every 5
                        years).

                5)    Responsibilities   of   the   PA    Department of Environmental
                      Resources:


                      - Designate the watershed areas.
                      - Coordinate planning efforts with the counties.
                      - Review and approve plans.
                      - Administer a grant program which provides the counties with
                        a 75% funding reimbursement for the preparation of Phase I
                        Scopes of Study and Phase II Plans. The grant program also
                        provides municipalities with a 75% reimbursement to help
                        cover the eligible costs associated with the preparation and
                        subsequent    administration    of   storm   water     management
                        ordinances.


                6)    Properties can be developed without causing adverse impacts to
                      downstream areas if developers control the quantity, velocity,
                      and  direction. of     storm water runoff.      The Storm Water
                      Management Plan will include specific standards and criteria
                      that define the basic control mechanisms. The purpose of the
                      plan is not to dictate to a developer how to meet specific
                      standards.   Instead, the developer will be provided with a
                      guide that includes a range of possible approaches that may be
                      followed in order to ensure a high degree of success in meeting
                      those standards.


                7)    It is important for the municipalities within a particular
                      watershed area to participate in the storm water management
                      planning   process.    By attending WPAC meetings, municipal
                      officials will be kept abreast of the current status of the
                      Storm   Water   Management Plan as well as how the plan's
                      recommendations   may    affect   their   community.      Municipal
                      officials can also provide the engineering consultant with a
                      wealth of information on problem areas and other storm water
                      concerns within their municipalities.       Another way in which
                      municipal officials can participate in the planning process is
                      by reviewing the Phase I and Phase II planning documents and
                      forwarding their review comments to the consultant for possible
                      incorporation into the plan.




                                                    3











                 8)   During    the   Phase I study, each municipality within the
                      watershed area is asked to complete a municipal questionnaire
                      in order to identify problem areas and municipal storm water
                      concerns.    The municipalities are also asked to designate a
                      local official to represent the municipality at the WPAC
                      meetings.    This official should be familiar with storm water
                      problems in the community.

                 9)   When    the   local    officials    are completing the municipal
                      questionnaire     for   the current project, they should only
                      identify those storm water problem areas located within the
                      Lake Erie and Elk Creek watersheds. Even if no problems exist
                      within a particular municipality, the officials should note
                      that fact and return the questionnaire to the Erie County
                      Department of Planning.

                 10)  Once the plan is adopted by the County, those municipalities
                      which have already adopted storm water management ordinances
                      will be required to revise their ordinances (if necessary) in
                      order to incorporate the plan's standards and criteria.

                 11)  PA    DER   will    not   provide grant funds retroactively to
                      municipalities that have already adopted storm water management
                      ordinances.


                 12)  General    Rule:     Post-development runoff should no       t exceed
                      pre-development runoff.

                 13)  There    are    353 watersheds throughout the Commonwealth of
                      Pennsylvania.

                 Mr. Maslanik noted that members of the committee can contact him at
                 (412) 269-5828 if they have any additional questions. In addition,
                 committee members that have any specific questions on the DER storm
                 water regulations or guidelines should contact Mr. Durla Lathia at
                 (717) 541-7905.


                 Other Business


                 Mr. Skellie noted that one more meeting will be held during the Phase
                 I project effort in order to review the draft Scope of Study. This
                 meeting is tentatively scheduled for early June 1991. All Phase I
                 work activities, including the preparation of the final report, must
                 be completed by the June 30, 1991 contract deadline.

                 Adjournment


                 There being no further business, Mr. Skellie adjourned the meeting at
                 8:30 P.M.

                                              ATTACHMENT  A



                                     BRIEF HISTORY/CURRENT STATUS
                                                   OF
                                 STORM WATER MANAGEMENT IN ERIE COUNTY




               Storm water management has been traditionally defined as measures
               used by property owners and local governments to eliminate or at
               least reduce the adverse impact resulting from excessive storm water
               runoff and to control the path of runoff through space and time. In
               the past, the basic approach to managing this runoff has been to
               achieve maximum convenience      at a given site by discharging to the
               nearest convenient location      any excess surface water as quickly as
               possible following a storm.      This removal has been accomplished most
               typically by conveying the       water through a storm sewer or other
               closed system.     This process  of passing on storm water runoff merely'
               shifts the location of the problem and all too often aggravates the
               situation    downstream    and   creates   a    flood   hazard in other
               communities.    An additional concern created by this approach is that
               groundwater supplies in the area may be diminished.

               Even in areas where there has been no flooding problem in the past,
               there is cause for concern.         As land development continues, the
               percentage of impervious land surface 'increases in once rural or
               semi-rural areas. Paved roads, sidewalks, rooftops, parking lots and
               other    improvements all contribute to the problem.           Areas that
               previously had no flooding begin experiencing problems; areas where
               flooding has been a problem now may begin to experience an even more
               serious problem.

               The solution of passing one's water problems downstream is no longer
               acceptable.    The potential damage created by such a practice cannot
               be tolerated as development continues. Recognizing the need to deal
               with this serious and growing problem, the Pennsylvania General
               Assembly enacted the Storm Water Management Act (Act 167 of 1978).
               Act 167 institutes a comprehensive program of storm water planning
               and management on a watershed level. The Act requires counties to
               prepare and adopt storm water management plans for each watershed
               located    in   the   County.    These plans are to be prepared in
               consultation with municipalities located in the watershed, working
               through a Watershed Plan Advisory Committee (WPAC). The plans are to
               provide for uniform technical standards and criteria throughout a
               watershed for the management of storm water runoff from new land
               development sites.     According to the Storm Water Management Act, the
               municipalities will then be required to adopt ordinances, codes and
               regulations which are consistent with the storm water management
               plans approved for each watershed.

               The Department of Environmental Resources is authorized to administer
               grants to municipalities and counties to assist or reimburse them for











                costs in preparing official storm water management plans and actual
                administrative, enforcement, and implementation costs and revisions
                to official plans for storm water management required by this act.
                The grants are equal to 75% of the allowable costs incurred by any
                municipality or county.

                In 1981, Erie County prepared a pilot watershed plan for the Lake
                Erie and Elk Creek watershed areas which encompassed the entire
                coastline of Lake Erie in Pennsylvania. (It should be noted that all
                or portions of 25 municipalities in Erie County are affected by these
                drainage areas - See Exhibit A.)            The plan, which consists of a
                series of 14 volumes, was completed with funds provided by the PA
                Coastal Zone Management Program and the PA Bureau of Dams and
                Waterways Management (BDWM).        Volume 1 is a technical document
                written for the individual interested in the more detailed aspects of
                the plan. The remaining volumes in the series, Volumes 2 through 14,
                represent applications of the plan developed in Volume 1 to specific,
                features of the various subwatersheds within the Lake Erie and Elk
                Creek watershed areas. Although Act 167 required the County to adopt
                a Storm Water Management Plan for all watersheds by May 14, 1987,
                only a small portion of the Lake Erie and Elk Creek Watershed Plan
                (Volumes 1 and 8) was implemented due to a lack of interest at the
                local    level.     However, it should be noted that the two (2)
                municipalities located within the Volume 8 study area, North East
                Borough and North East Township, have adopted Storm Water Management
                Ordinances (September 23, 1983 and April 14, 1986 respectively).
                To-date, these are the only two (2) municipalities in Erie County
                that have adopted Storm Water Management Ordinances in accordance
                with a State approved Storm Water Management Plan. In addition,
                Summit Township and Millcreek Township adopted Storm Water Management
                Ordinances in 1990 as amendments to their subdivision regulations
                under the authority of the Pennsylvania Municipalities Planning Code,
                Act 247 of 1968, as amended.

                Over the last several years, Erie County and BDWM have been working
                on a storm water management implementation for the County's nine (9)
                watershed areas:


                                    1) Lake Erie Watershed
                                    2) Elk Creek Watershed
                                    3) French Creek Watershed
                                    4) Conneaut Creek Watershed
                                    5) Ashtabula River Watershed
                                    6) Cussewago Creek Watershed
                                    7) Muddy Creek Watershed
                                    8) Oil Creek Watershed
                                    9) Brokenstraw Creek Watershed

                As of March 1991, the County's anticipated schedule for storm water
                management planning is as follows:

                1991   Develop a Scope of Study (Phase I) for the Lake Erie and Elk
                       Creek watershed areas.        The purpose of this study will be to
                       review the pilot watershed plan which was completed in 1981 in
                       order to determine the level of effort required by the County
                       to satisfactorily complete a Storm Water Management Plan for
                       these watersheds. (Note: The Scope of Study must be completed
                       by June 30, 1991.)

                1992   Update the Storm Water Management Plan (Phase II) for the Lake
                       Erie and Elk Creek watersheds. Erie County will subsequently
                       adopt    the    Updated Storm Water Management Plan, thereby
                       requiring the municipalities located within these watershed
                       areas to enact ordinances consistent with the plan.

                1994 - Develop a Scope of Study (Phase I) for the French Creek
                       watershed in conjunction with Crawford, Mercer and Venango
                       Counties.


                1995 - Develop a Storm Water Management Plan (Phase II) for the
                       French Creek watershed.




                           NOTE: This schedule is subject to change depending
                               upon the availability of funds at both the
                                  State and County levels of government.

                            facilities design and Chester Engineers is a leader in the application of these
                            capabilities to the design of water and wastewater treatment and piping facilities.

                            Chester's CAD/E facilities
                            consist of an Intergraph

                            CADD software, Chester
                            Engineers has the capability to
                            develop landfill desigris as well
                            as other applications. These
                            facilities are programmed,
                            operated and maintained by our data processing experts and computer programmers
                            who are trained and experienced in the use of computers for solving design problems.

                            In CAD/E, engineering drawings are constructed as closely as possible to the normal
                            construction sequence and are generated on one integral plane encompassing the
                            entire limits of the work. This assures continuity between drawings because each
                            discipline works within the same limits. Overlays which depict each of the functional
                            disciplines, e.g. architectural, electrical, mechanical, structural, etc., can be viewed
                            separately, together, or in any combination in order to prevent interferences. All
                            drawing dimensions on CAD/E are entered at full scale and the computer maintains
                            the relationship between lines for the drawing scale that is required. This reduces the
                            need for repetitive checking, makes dimensional calculations unnecessary and
                            assures that drawings are always to scale.

                            Material and quantity take-offs and schedules can be compiled and printed parallel
                            to the production of drawings. The CAD/E system assures that drawings are
                            consistent in form and notation. If desired, sections or whole drawings can be

                          enlarged for study or reduced for convenience. Experience has proven that the
                          production of readily understandable, accurate, and reliable drawings serves to
                          increase contractor confidence and reduce contingency allowances normally associated
                          with estimates.


                          With CAD/E, drawing changes during the construction phase are easily accomplished.
                          Field change orders can be accurately recorded on the drawings and the effect that they
                          have on all aspects of the facility can be evaluated to determine if any interferences
                          will result.


                          In summary, the CAD/E system provides our engineers, architects and designers with
                          the capability to create, draft, analyze and control a project from the initial process
                          selection or preliminary design phase through the final design, construction and
                          operation phases. CAD/E has added precision, speed and flexibility to our drafting
                          and design efforts which translate to improved designs and reduced costs during both
                          the design and construction phases of projects.

                 THE USE OF ADVANCED TECHNOLOGIES


                 Computerized Computation and Modeling

                 A key component of Chester Engineers' approach to our stormwater investigations and
                 planning studies consists of maintaining and using a full compliment of computerized
                 computational and modeling software. Due to the nature of the computations involved in
                 estimating runoff and sizing stormwater management and control facilities, awide variety of
                 computer software has been developed. In order to be fully responsive to the various needs
                 of our clients, Chester Engineers maintains a library of and working familiarity with a wide
                 range of computational and modeling software. When circumstances warrant, we have
                 developed new and/or customized existing software in-house to meet special needs and
                 enhance effectiveness. This proprietary software is added to our library for use on future
                 projects. A partial listing of the software maintained for use in conjunction with our

                 Remote Sensing System Data Acquisition

                 An important parameter in stormwater modeling is land cover / land use. The accurate
                 description of existing land cover / land use is a prerequisite for accurate stormwater
                 modeling. The Chester Engineers has used remotely sensed data available from a the
                 complete range of platforms to derive the land cover / land use information necessary for
                 stormwater modeling, including the following:

                                 Traditional low level aerial photographs
                                 Color infrared high altitude aerial photographs acquired as part ofthe National
                                 Aeronautic and Space Administration's (NASA) National High Altitude
                                 Photography Program (NHAP)
                                 Landsat 5 Thematic Mapper (TM) multi-spectral satellite imagery providing
                                 a 30 meter ground resolution
                                 Specially ordered French SPOT Image Corporation SPOT1 panchromatic
                                 satellite images providing a 10 meter ground resolution

                 Remotely sensed data from these sources are preprocessed, enhanced and manually and/or
                 digitally classified into land cover / land use categories. Expert system rule based queries
                 have been used to extract additional information necessary to delineate industrial areas within
                 urban areas, vegetation within urban areas and recent land cover changes.


                 Digital Data Acquisition

                 Since stormwater investigations by nature lend themselves to computer analysis, efficiency
                 is enhanced when the basic data can be acquired in or economically transformed into digital
                 form. The Chester Engineers has considerable experience in the use of such data. TheChester
                 Engineers routinely uses ground slope and aspect information derived from United States
                 Geologic Survey Digital Elevation Models (U.S.G.S. DEMs) and Defense Mapping Agency
                 Digital Elevation Models (DMA DEMs); road, stream and municipal boundary information
                 obtained from U.S.G.S. Digital Line Graphs (DLGs); and land cover information derived
                 from the previously referenced satellite acquired data. These data are acquired in digital form,
                 and as such can be readily incorporated into many computerized analysis applications.

                 Some important information is not available in digital form and must be digitized prior to use.
                 We have experience in using information which has been digitized by both hand and scan
                 digitization methods. Digitized themes frequently used by Chester Engineers in our
                 stormwater modeling activities include watershed boundaries, soils information and wet-
                 lands locations.

                 Geographic Information Systems Applications

                 Geographic Information Systems (GIS) are digital computer systems for capturing, process-
                 ing, managing, displaying, modeling and analyzing geographically referenced spatial data.
                 Since all of the basic data required for stormwater modeling are geographically referenced,
                 GIS technologies are boonto stormwatermanagement efforts. Wemake extensiveuse of GIS
                 technologies in order to capture, organize and process the many layers of information
                 necessary to complete stormwater modeling on any scale. The GeoSpatial Solutions division
                 of Chester Engineers uses ERDAS'- and ARC/INFO'm GIS software to compile and process
                 information and provide data to our specifications for direct input into our stormwater
                 models. We have used this approach on a number of our projects to date. In every instance,
                 the use of diis technology has served to increase the amount and accuracy of the data provided
                 while minimizing the cost of data processing.

                  PENNSYLVANIA ACT 167 STORMWATER MANAGEMENT PLANNING:
                  PHASE I

                  Watershed stormwater management planning under Pennsylvania's Stormwater Manage-
                  ment Act (Act 167) is a two phase process. The first phase consists of the preparation of a
                  Scope ofStudy. Thepurposes of theScope ofStudy is to establishplan outcomes thatwill meet
                  the objectives of Act 167; determine the cost-effectiveness of study procedures; provide
                  consistency between county planning efforts; and eliminate duplication of effort. The
                  completed Scope of Study includes Phase Il task descriptions; a time schedule for the
                  completion of Phase U; descriptions of the level of effort required to complete major tasks;
                  and cost estimates for the completion of Phase H. As such, the Scope of Study is an integral
                  part of the plan, providing detailed guidance for plan development.

                  The value of consultant experience is at a premium in preparing the Phase I Scope of Study.
                  To alarge extent, decisions relative to plan approach and estimates of required levels of effort,
                  time requirements and costs must be based upon the consultant's judgement guided by
                  relevant experience. The Chester Engineers is pleased to have participated in the develop-
                  ment of the following Act 167 Scopes of Study.


                  Glade Run Phase I Scope of Study

                  The Glade Run watershed is approximately 25 square miles in size. It is located in Armstrong
                  County, Pennsylvania and encompasses land which is primarily rural in nature. The far
                  northern portion of the watershed has been heavily stripped for coal, but the majority of the
                  watershed remains forested or is used for agricultural purposes. Municipalities in the
                  watershed report increasing interest in residential development. Recent construction of an
                  industrial park in the area appears to signal the beginning of an increase in both commercial
                  and residential development in the area. These conditions pointed to the advisability of
                  completing Act 167 watershed stormwater management planning andplacing recommended
                  stormwater management controls into place prior to the advent of extensive development.

                  In 1986, The Chester Engineers, in cooperation with the Armstrong County Department of
                  Planning, prepared the Phase I Scope of Study for the Glade Run Stormwater Management
                  Plan. As required, the Scope of Study outlined the approach and procedures to be followed
                  during the preparation of the Phase 11 Plan and developed associated cost estimates and
                  anticipated completion schedules. The Phase I Scope of Study received the approval of
                  Armstrong County and the Pennsylvania Department of Environmental Resources.

                      Turtle Creek Phase I Scope of Study

                      The Turtle Creek watershed is situated within Allegheny and Westmoreland counties in
                      southwestern Pennsylvania. It encompasses approximately 150 square miles and includes all
                      or portions of 30 municipalities. The Allegheny County portion of the watershed (roughly
                      1/3) is extensively developed into urban, commercial, industrial and residential land uses.
                      The upstream, Westmoreland County portion of the watershed contains some urban concen-
                      trations, but also large tracts of undeveloped land. Flooding in areas of the Turtle Creek
                      watershed has long been a problem. Act 167 planning was initiated to place necessary
                      controls into place before anticipated future development exacerbates existing flooding
                      problems.

                      Conneaut Outlet Phase I Scope of Study

                      The Conneaut Outlet watershed is located in Crawford County, northwestern Pennsylvania.
                      A total ofnine municipalities are situated within the watershed which encompasses a drainage
                      area of approximately 90 square miles. Factors of particular interest in this project are that
                      a major lake (Conneaut Lake) is situated in the upper reaches of the watershed and a large
                      swamp (Conneaut Marsh) occupies much of the lower area of the basin. The Phase I Scope
                      of Study addressed the existence of these major hydrologic features by incorporating
                      supplemental stream flow gaging and analysis activities designed to characterize the effects
                      of these features on runoff and stream flow.

                  The Conneaut Outlet Phase I Scope ofStudy was completed in 1989 with the cooperation of
                  the Crawford Planning Commission. The document has been approved by Crawford County
                  and the Pennsylvania Department of Environmental Resources.


                  Breakneck Creek Phase I Scope of Study

                  The Breakneck Creek watershed is situated primarily within Butler County in western
                  Pennsylvania. A small portion of the upper reaches of the watershed is in Allegheny County.
                  A total of eleven municipalities lie in the watershed which encompasses approximately 43
                  square miles. This area is expected to develop at a rapid rate within the next five to ten years
                  with large developments currently in the preliminary planning stages. This impending
                  development was the major impetus for initiating the Act 167 planning process and was
                  identified as a major concern to be addressed in the Phase H effort.

                  The Breakneck Creek WatershedPhaseIScope ofStudywas completedby Chester Engineers
                  in cooperation with the Butler County Planning Commission in 1989. The report was
                  approved by Butler County and accepted by the Pennsylvania Department of Environmental
                  Resources.



                  BuR Run Phase I Scope of Study

                  The Bull Run watershed is located in southeastern Union County, Pennsylvania. The Bull
                  Run watershed is contained in three municipalities and covers an approximately 7.5 square
                  mile area. The predominant land use in the watershed is agriculture, which is mainly located
                  in the central and western portions of the watershed. Residential, commercial and industrial
                  land use is concentrated in the vicinity or Lewisburg, which occupies the eastern portion of
                  the basin.


                  Chester Engineers, together with the Union County Department of Planning completed the
                  Bull Run Watershed Phase I Scope ofStudy in 1990. The document was approved by Union
                  County and the Pennsylvania Department of Environmental Resources.

                  Monongahela River Phase I Scope of Study

                  In 1990, Chester Engineers, in cooperation with the Allegheny County Planning Department
                  completed the Monongahela River Phase I Scope of Study for the designated Monongahela
                  River watershed in Allegheny County, Pennsylvania. The watershed encompasses approxi-
                  mately 106 square miles and all orportions of 34 municipalities. Much ofthe northern portion
                  of the watershed is very highly urbanized. This includes the downtown, Golden Triangle and
                  Oakland areas of the City of Pittsburgh and several extensively developed suburbs. Because
                  development in these highly urbanized areas has essentially reached the saturation point,
                  there is little need for hydrologic modeling for the purpose of developing standards and
                  criteria for new development in such areas. The southern areas of the watershed, on the other
                  hand, are much less densely developed and include large expanses of rural areas. In this
                  portion of the watershed, the future development potential is high and the need for modeling
                  is clear.


                  Based upon these considerations, the Phase I Scope of Study outlined a procedure for
                  delineating those areas requiring differing levels of modeling and described the differing
                  levels of effort and direction of emphasis to be followed in the urban (north) and suburban
                  (south) portions of the watershed.

                  The Monongahela River Phase I Scope of Study was accepted by Allegheny County and
                  approved by the Pennsylvania Department of Environmental Resources.


                  Redstone Creek Phase I Scope of Study

                  The Redstone Creek watershed is located in Fayette County in southwestern Pennsylvania.
                  All orportions of eleven municipalities lie within the watershed which drains northward from
                  the Uniontown area to the Monongahela River. Preparation of this Phase I Scope of Study
                  is currently underway.


                  Shenango River Phase I Scope of Study

                  The Shenango River watershed lies in Crawford, Lawrence and Mercer counties in western
                  Pennsylvania and portions of eastern Ohio. Portions of a total of 46 Pennsylvania
                  municipalities lie within the basin. A notable feature of the Shenango River watershed is the
                  fact that it contains several sizable flood control /recreational lakes. Outlining the procedures
                  for accounting for the effects ofthese waterbodies on stormwater runoffwill be amajor aspect
                  of the Phase I Scope of Study which is currently under development.

                  PHASE U

                  Phase][Iisthefinal and major component of the watershed stormwater management planning
                  process under Pennsylvania's Stormwater Management Act. The Phase II Stormwater
                  Management Plan is the basis for the entire management system and ongoing stormwater
                  management activities. The key elements of the Phase II Stormwater Management Plan
                  include the following:

                                  Hydrologic and hydraulic modeling of the watershed to permit the rational
                                  development of stormwater management performance criteria reflecting
                                  local conditions.


                                  Development and definition of specific criteria and standards to be used in the
                                  management of stormwater with the watershed.

                                  Identification of the optimal institutional arrangement and procedure for
                                  implementing the plan on a watershed basis.

                                  Recommendation of specific activities which must be undertaken by each
                                  municipality in order to implement the plan on the local level. Ibis includes
                                  the identification of key elements of required local ordinances and
                                  regulations.

                  The production of a technically sound Phase II Stormwater Management Plan requires that
                  the consultant be expert the technical elements associated with hydrologic modeling and
                  stormwater control. For the final plan to be capable of being implemented and workable, the
                  consultant must also be experienced in woddng with local government officials and
                  developing practical model ordinance provisions. We point to the following Act 167 Phase
                  II Stormwater Management Plans as evidence of our expertise and experience in these fields.

                  Glade Run Phase H Stormwater Management Plan

                  The Glade Run Phase Il Stormwater Management Plan was completed and approved by the
                  Pennsylvania Department of Environmental Resources in 1990. Data describing topography,
                  soil types, land use patterns, stream characteristics, stream restrictions and flood prone areas
                  were input to the Penn State RunoffModel to determine watershed hydrologic characteristics.
                  Landsat Thematic Mapper (T`M) and NASA High Altitude Photograph (NHAP) images were
                  obtained and classified to identify land cover characteristics. This information was combined
                  with digitized Soil Conservation Service soil maps using the ERDASI and ARC/INFO'
                  image processing and GIS systems to assign runoff curve numbers. This data was combined
                  in the GIS with USGS digital elevation models to produce the data set required by the Penn
                  State Runoff Model. Once calibrated the model, was used to develop watershed wide
                  stoxmwater control standards and specific performance criteria applicable in 90 individual
                  subbasins delineated throughout the watershed.

                  The Planpresents recommendations relativetothe institutional measures tobetakento codify
                  the identified standards and criteria defined by the technical elements of the Plan. None of
                  the municipalities in the watershed had a subdivision/land development ordinance. Instead,
                  the municipalities relied upon a county level subdivision/land development ordinance
                  administered by the Armstrong County Department of Planning. In view of this situation,
                  Chester Engineers recommended that the stormwater management requirements be incorpo-
                  rated into the county subdivision/land development ordinance andthatreviews and approvals
                  relative to developers' stormwater controls be performed on the county level. Specific
                  language to be contained in the amended county ordinance was identified in the Plan.

                  hydrologic modeling using the Penn State Runoff Model.

                  The large size of the watershed and the desire to as closely as possible retain and reflect the
                  actual stream topology in the construction of the model produced a large number of subbasins
                  to be modeled (in excess of 500). In response, Chester Engineers modified the Penn State
                  Runoff Model and used the modified version to speed data input, facilitate analysis of model
                  output and permit simultaneous modeling of over 160 subbasins.

                  Watershed wide stormwater standards recommended and specific control standards were
                  developed for each of the over 500 subbasins comprising the Turtle Creek watershed. A
                  review of the current status of applicable ordinances revealed that the majority of the
                  municipalities within the watershed operate under their own subdivision/land development
                  ordinances. However, most of the existing ordinances are deficient in specific stormwater
                  management provisions. In order to retain the current institutional structure, the Plan
                  recommended that implementation be achieved through local municipal ordinances. The
                  Plan presented model local ordinance provisions to be used by each municipality to bring
                  existing ordinances into compliance. In order to encourage consistent application of the
                  stormwater management system across municipal and county boundaries, the Plan recom-
                  mended that the Allegheny County Department of Planning and the Westmoreland Conser-
                  vation District perform an ongoing review and comment function during plan implementa-
                  tion and administration.

                 MISCELLANEOUS STORMWATER INVESTIGATIONS

                 The Chester Engineers has been involved in a number of stormwater investigations apart from
                 our Act 167 stormwater management activities. These investigations include watershed wide
                 studies roughly paralleling Act 167 plans; investigations into site specific problems; and
                 investigations preparatory to the design of drainage facilities.


                 Broadway Interceptor Area Stormwater Management Plan

                 Under contract to the Char-West Council of Governments, Chester Engineers developed a
                 sto.rmwater management plan for the Broadway Interceptor drainage area in the McKees
                 Rocks Borough, and Stowe and Kennedy township areas in southwestern Pennsylvania. This
                 project incorporated most of the elements of an Act 167 stormwater management plan. It
                 included the analysis ofexisting conditions, use ofthe Penn State RunoffModel forpeak flow
                 computations, the development of engineering alternatives and the establishment of the
                 necessary institutional structure necessary for plan implementation.


                 Lewis Run Hydraulic and Mapping Study

                 The Chester Engineers completed ahydraulic and mapping study ofthe Lewis Run watershed
                 in southwestern Pennsylvania in orderto develop the database required for further stormwater
                 management planning. A significant portion of this investigation involved the development
                 of a stormwater drainage map of the entire watershed. A detailed stream survey was
                 conducted to identify existing problem areas and to determine the hydraulic capacities of
                 major stream crossings.


                 Franklin Park Borough Runoff Control Study

                 This study consisted of the inspection and analysis of all existing stream obstructions within
                 the Rippling Run and Lowries Run watersheds in the Borough of Franklin Park, Pennsylva-
                 nia. Baseline and future runoff conditions were established using aerial photography, USGS
                 topographical maps and the Penn State Runoff Model. Existing problem areas and potential
                 future problems were identified using the model. A ten year implementation plan consisting
                 of recommended improvements to the stormwater system was developed. A stormwater
                 management ordinance and related regulations and standards to implement stormwater
                 control for future development were also developed as part of the study.

                 Fox Hollow Stormwater Management Plan

                 Fox Hollow is a 2+ square mile watershed in Williamsport, Pennsylvania which is divided
                 into three main land use types. The steeply sloped headwater area is suburbanizing, with
                 increasing peak flows causing channel erosion. The central portion is an older, residential
                 area with undersized stream culverts. 'Me lowest portion is a very flat, prime industrial area
                 that experiences frequent flooding. For water to exit the area, it first must pass through
                 inadequate highway culverts and the Susquehanna River Flood Level System. A comprehen-
                 sive stormwater management plan that addresses existing and projected future stormwater
                 handling requirements was developed.

                 The hydrologic design was based on computer simulations using the Penn State Runoff
                 Model. The structural alternatives evaluated included diversions, flood water detention
                 basins, flood pumping stations, and conventional interior storm drainage facilities. The
                 project also addressed the need for on-site runoff controls for both existing and new
                 development. The recommended implementation plan included preliminary construction
                 cost estimates and a prioritized implementation sequence.



                 Town of McCandless Stormwater Master Plan

                 The Town of McCandless is a rapidly growing community near the City of Pittsburgh,
                 Pennsylvania. The Town encompasses approximately 20 square miles and contains four
                 separate watersheds. The Cbester Engineers, under contract to the Town, developed a master
                 plan providing direction and guidance to managing runoff from the rapidly developing areas
                 of the municipality.

                 The scope of services included an investigation of rainfall, intensity, development of existing
                 and projected land uses, calculation of the resulting quantity of stormwater runoff and
                 subsequent implementation of the plan. The plan, which was developed for each watershed,
                 provides the municipality with the recommended measures to be taken to control urban
                 stormwater runoff.

                 Port Allegany Stormwater Master Plan

                 The Borough of Port Allegany has only a rudimentary stormwater drainage system. Most
                 surface water drainage is through open ditches. The portion of the piped drainage system that
                 does exist has capacity restrictions where it passes under buildings and railroad tracks. The
                 Master Plan developed by Chester Engineers provided a conceptual design of a completely
                 new storm sewer system for the entire Borough. The design objective was to divert as much
                 water as possible away from the business and industrial areas that were experiencing
                 flooding. Since the site evaluation indicated virtually no opportunities for on-site stormwater
                 management techniques, the project was conducted in a traditional storm sewer planning
                 framework. The project report presented line capacities, sizes and grades as well as cost
                 estimates and implementation priorities.


                 Assessment of Huntington Storm Sewer Master Plan

                 The Chester Engineers has been privileged to have served the City of Huntington, West
                 Virginia for many decades. In 1947, Chester Engineers prepared a Master Planfor Storm
                 Sewers for the City. Available funds has limited the extent to which of the recommended
                 storm sewer system has been constructed. However, recent efforts are being made to proceed
                 with the construction of needed storm sewer facilities. Upon our recommendation, Chester
                 Engineers conducted a review of the procedures employed and land cover and rainfall data
                 used during the preparation of the 1947 Plan to determine whether duplication of the detailed
                 and expensive investigations could be avoided. The original sewer design was based upon
                 the Rational Method which computes stormwater runoff from land cover and design storm
                 precipitation characteristics. Therefore, our assessment of the continued validity of the Plan
                 -was based upon our assessment of the validity of the rainfall data and land cover statistics
                 employed in 1947.

                 The rainfall intensity-duration curves used in 1947 were compared to current design
                 standards and were found to reasonably conform. An analysis of current land cover and land
                 use was carried out to determine the current percent impervious statistics for comparison to
                 the 1947 estimates. This analysis was performed using a combination of digital and analog
                 methods of analysis combined in a rule based expert system query. The basic information
                 used to classify land use was obtained from a SPOT panchromatic scene and NASA National
                 High Altitude Photography (NHAP) program photographs. In was determined that the
                 estimates used in the 1947 analysis were sufficiently accurate to validate their continued
                 validity for 37 of the 48 sewer districts in the City. The report concluded that there is no need
                    duplicate the calculations in the 37 sewer districts, which permits rapid and economical
                 progress to the design phase for those areas of the City.

                 HEC 2 Analysis of Spring Creek Channel Relocation

                 The relocation of a portion of the Spring Creek channel is an aspect of an interceptor sewer
                 construction project designed by Chester Engineers for the Harrisburg, Pennsylvania
                 Authority. In support of the acquisition of necessary permits, Chester Engineers conducted
                 an analysis of the effects of the channel relocation upon water surface profiles and 10, 50, 100
                 and 500 year floodways. This was accomplished by obtaining the HEC 2 models used in the
                 development of the Flood Insurance Study for the area. The models were modified to reflect
                 the proposed channel alterations and run to determine changes to water surface profiles. This
                 analysis determined that the proposed channel relocation will not adversely affect water
                 surface profiles nor expand the floodway.


                 Chartiers Creek Interceptor Capacity Study

                 The Allegheny County Sanitary Authority's Chartiers Creek Interceptor conveys wastewater
                 collected in 22 municipalities in Allegheny County, Pennsylvania. Wastewater conveyed by
                 this interceptor is collected by a combination of separate sanitary and combined sewer
                 systems. The Chester Engineers is in the process of completing an assessment of the capacity
                 of this interceptor in order to define options available relative to expansion of the current
                 service area and the reduction of combined sewer overflows through the acceptance of
                 additional stormwater runoff. We are using the U. S. Environmental Protection Agency's
                 Stormwater Management Model (SWMM) to simulate existing and future dry and wet
                 weather flows from the current tributary area, model the performance of the interceptor and
                 assess the reserve capacity of the facilities.

                 Assembly of the hydrologic characteristics database is being accomplished using the remote
                 sensing, image analysis and GIS techniques we employ as standard procedure during our Act
                 167 stormwater management planning activities. The database will be expanded to include
                 demographic information necessary to estimate dry weatherwastewater flows under SWMM.
                 This will be accomplished by digitizing U.S. Census Tract boundaries and overlaying the
                 associated demographic statistics over identified sewer system boundaries in the GIS
                 environment.

                 STORMWATER CONTROL PLAN REVIEW SERVICES


                 A key element of stormwater management plans is the ongoing review of developers'
                 proposed stormwater control facilities at the local and county levels of government. It is
                 importarittothe success of the overall stormwater management plan that the control facilities
                 actually constructed are designed in conformance with the plan's standards and criteria. The
                 Chester Engineers provides consulting services in support of such review activities as
                 illustrated by the following examples.


                 Allegheny County Plan Review Services

                 The Chester Engineers provides stormwater control plan review services to the Allegheny
                 County Department of Planning. These services include the review of stormwater control
                 plans submitted by land developers under the requirements of existing stormwater manage-
                 ment plans in the County. Our assessment of compliance with the plan requirements is used
                 by the County as the basis for recommending approval or disapproval of the developers'
                 submittals. This ongoing service provides Chester Engineers with an awareness of current
                 stormwater management practices. In addition, it provides us with valuable experience with
                 the interpretation and application of stormwater management criteria, standards and ordi-

                 nances.



                 Martinsburg Plan Review Services

                 As the City ofMartinsburg, West Virginia's consulting engineer, Chester Engineers conducts
                 detailed engineering reviews of all site development plans to ensure that proposed facilities
                 will meet the standards established by the City's stormwater management ordinance.



                 STORMWATER CONTROL FACHJTIES DESIGN

                 Stozmwater control facilities constructed in support of land development are the bottom line
                 in stormwater management. These facilities perform the function of implementing the runoff
                 control standards and criteria developed by stormwater management plans and codified in
                 stormwater management ordinances and regulations. The following are examples of Chester
                 Engineers experience in the design of such facilities.

                 Mdntyre Hospital Stormwater Control Facilities

                 The objective of this project was the development of an overall stormwater control system
                 for the project site which would meet the stormwater management principle of no increase
                 in peak runoff following development. This was accomplished through a system of swale
                 drainage ditches and conventional storm sewers which terminate in a large underground
                 storage culvert. The facility was designed as an off-line structure to permit low flows to
                 bypass the primary structure to reduce sedimentation and corrosion from winter road
                 treatment chemicals. The outlet was designed with multiple releases to permit only the
                 predevelopment peak flow rate for all storms up to the specified design storm. Storm flow
                 in excess of the outflow rate is stored and released gradually as inflow decreases. The Chester
                 Engineers worked closely with the landscape architect so that the stormwater control
                 facilities were integrated with the overall site grading plan for maximum aesthetic benefit.


                 McDonald's Corporation Stormwater Detention Facilities

                 The Chester Engineers was responsible for the design of a stormwater management facility
                 to limit post-development peak discharges to predevelopment levels. This was achieved
                 through the use of oversized pipe with reduced outlet capacity. Ibis represents a simple but
                 effective means of achieving the detention storage capacity necessary to reduce peak
                 discharge rates within the framework of a conventional storm sewer system for a single lot
                 development.


                 Cerro Copper Products Company Stormwater Facilities

                 This project consisted of the design of facilities to collect stormwater and process water
                 generated on an industrial site, store it as necessary to minimize peak discharge rates and
                 pump it to an existing municipal sewer system. Ile final design provides underground
                 storage of approximately one million gallons and apump station capable of discharging 9,000
                 gallons per minute of wastewater to the municipal system. Approximately 1,600 linear feet
                 of box culvert provides approximately 60% of the storage volume. This system will prevent
                 surcharge Erom the system back into the collection system for storms up to the ten year return
                 frequency. Longer return frequency storms will require the use of temporary additional
                 pumping capacity or coRecfion system surcharge.

                 projects.


                 Forty-Fort Borough Storm Sewer Facilities

                 This Federal Department of Housing and Urban Development project located in northern
                 Pennsylvania included the design of approximately 35,000 feet of 17 inch to 84 inch storm
                 sewers and appurtenances. The scope of work also included surface restoration and
                 reconstruction of streets, curbs, trees, lawns and sidewalks. Engineering services provided
                 by Chester Engineers included preliminary survey and design, final design andplans, general

                 Mapping and GIS Analysis for Planning and Stormwater Management

                 Our recently completed and on-going Act 167 Stormwater Management Planning efforts are
                 supported by GeoSpatial Solutions'development of digital geographic databases for land use
                 planning and input into the hydrologic models employed. These efforts include acquisition
                 and processing of aircraft and satellite imagery (National High Altitude Program photo-
                 graphs, digital SPOT imagery and multispectral Thematic Mapper data) and digital elevation
                 data to provide terrain and land cover information for subbasins within the watersheds under
                 study. Digital image enhancement, multispectral classification and GIS techniques are used
                 to combine the various types of data and to extract the information needed to define
                 hydrologic conditions within the watersheds. Other classes of information such as hydrologic
                 soils groups, transportation networks and administrative boundaries are captured using a
                 combination of scan- and manual digitizing techniques. The resulting vector data are
                 converted to raster form and included in the digital database. Image processing and GIS
                 analysis activities are performed using the ERDAS and ARC/INFO systems.

                 Satellite images and aerial photographs are used to provide land cover information. Soilunits
                 digitized from Soil Conservation Service (SCS) soils plats and terrain calculated from USGS
                 digital elevation models are combined to yield estimates of representative slopes, overland
                 flow lengths, tributary areas, percent impervious surface coverage and SCS runoff curve
                 numbers. Other information provided in the databases includes roads, hydrography and
                 political boundaries.

                 Data acquisition and GIS analysis activities were furnished in support ofthe completed Phase
                 U Act 167 Stormwater Management Plans for the 150 square mile Turtle Creek Watershed
                 and the 25 square mile Glade Run Watershed. Similar activities are in progress in support
                 of our on-going Phase 11 Act 167 Stormwater Plans for the 90 square mile Conneaut Outlet
                 Watershed, 7.5 square mile Bull Run Watershed and 106 square mile Monongahela River
                 Watershed.


                 Remote sensing and GIS techniques have also been used in the preparation of an update and
                 assessment of a Storm Sewer Master Plan for the City of Huntington, West Virginia, the
                 development of a Master Water Plan for West Deer Township, Pennsylvania and the
                 evaluation of the capacity of the Allegheny County Sanitary Authority's Chartiers Creek
                 interceptor. In each of these cases, the attributes of a variety of data sources and the
                 capabilities of remote sensing and GIS technologies were melded in applications supporting
                 classical civil/environmental engineering and planning projects.

                  Large-Area Database Development

                  GeoSpatial Solutions' staff have been responsible for the creation of geographic databases
                  for areas covering as much as 2,000,000 acres in the western U.S. These databases typically
                  included contiguous digital elevation data sets created from mosaicked digital elevation
                  models, land cover information derived from Landsat multispectral classifications, and other
                  information collected by digitizing and rasterizing hydrographic, transportation, soils, and
                  administrative themes.


                  GIS Terminal Configuration for the United States Bureau of Indian Affairs

                  GeoSpatial Solutions was responsible for configuring three high-performance workstations
                  for use as Geographic Information Systems Graphics Terminals by local offices of the U.S.
                  Department of the Interior Bureau of Indian Affairs. This work integrates with the Map
                  Overlay and Statistical (MOSS)/Map Analysis Package (MAP) family of software. The
                  principal use of these GIS terminals is foruse with MOSS/MAP and associated GIS software
                  but they also provide for local office automation processing such as word processing,
                  database management, spreadsheet and project management. In this way, the microcompu-
                  ters can be put to maximum use for both office and technical work. The terminals are also
                  integrated with graphics devices such as laser printers and pen plotters.


                  Alaska Initial Attack Management System

                  GeoSpatial Solutions developed and implemented an operational initial Attack Management
                  System for the U.S. Department of the Interior Bureau of Land Management (BLM) Alaska
                  Fire Service. This system was required to interface with the Department of the Interior's Map
                  Overlay and Statistical (MOSS)/Map Analysis Package (MAP).


                  Tlie project involved the development of a new, special purpose geographic information
                  system (GIS) to augment the capabilities of MOSS/MAP. The system required the
                  integration of data from a wide variety of disparate data sources into a comprehensive GIS.
                  Data from Automated Lightning Detection System (AIDS) andRemote Automated Weather
                  Stations (RAWS) as well as digital terrain data, wildfire fuel types and fire suppression status
                  can be integrated using this system. The system interfaces with the U.S. Forest Service fire
                  modelingprogramBEHAVE. Compatibffity widiMOSSftAAP is maintained throughoutthe
                  system. The system integrates a wide variety of functionality via extensive use of macros to
                  assist applications processing. The final product is a comprehensive Initial Attack Manage-
                  ment System to address the specific information needs of BLM's fire suppression activities
                  in Alaska.

                 Quick Response Atlas and Terrain Mapping for Fire Departments

                 Fire departments require accurate and up-to-date information on residences in their districts.
                 In addition, fire departments with the responsibility for controlling wildfires and fires in the
                 wildland/urban interface can benefit from terrain and fire fuels information. Using the ARC/
                 INFO GIS system and digital data from a variety of sources including local planning agencies,
                 United States Geological Survey (U.S.G.S.) Digital Line Graph (DLG) files, U.S. Census
                 TIGER files, digital terrain models and aerial photographs, GeoSpatial Solutions has
                 developedmaps and adigital database for the Cherryvale Fire Protection District in Boulder,
                 Colorado. The resulting digital information is easily updated and can be used to provide a
                 variety of data and map types.


                 12S WS Function for Workshop Processing of Classified Images

                 GeoSpatial Solutions developed anew image processing capability for the U.S. Department
                 of the Interior Bureau of Land Management (BLM) at their Denver Service Center. Using
                 the local hardware processing capabilities of the International Imaging Systems (12S) Model
                 70 Image Display, we developed a capability for interactively roaming, zooming and
                 pseudocoloring a classified image. This capability did not previously exist and was required
                 for rapid assessment of classified imagery by field personnel in land cover mapping.

                 The importance of image classification workshops for field office personnel cannot be
                 overemphasized. Any capabilities of the image processing system which will improve the
                 flow of classification and evaluation process is a great asset in the mapping process. Tbrough
                 effective software development techniques and an in-depth understanding of the information
                 -requirements of field personnel, this software development effort significantly improved the
                 BLMs workshop display capabilities.


                 BLM Wyoming Coal Verification Work

                 GeoSpatial Solutions recently conducted a project for the U.S. Department of the Interior in
                 Wyoming to develop and implement a Coal Production Verification System. This system
                 integrates a dBase IH+ application developed on an IBM PC with the MOSS[MAP software
                 to provide true relational database management capabilities integrated with GIS capabilities.
                 The system also interfaces with a digital photogrammetric system for the verification of
                 volumes removed from coal mines. Other software required by geologists and mining
                 engineers is also available as part of this system. The system is unique in that it integrates
                 a wide variety of public domain and commercial software to address the problem of coal
                 production verification in a comprehensive manner.

                  MOSS Symbols Software

                  GeoSpatial Solutions recently completed major revisions to the Departm            of the Interior
                  Bureau of Land Management's MOSS software for mapping symbol generation and
                  management. This work involved the development and implementation of new mapping
                  symbols and re-writing of the software to permit more user flexibility in managing MOSS
                  mapping symbols.

                  The software has provided a MOSSJMAP capability previously unavailable to users. It
                  combines several FORTRAN 77 routines with a macro driver to facilitate easy use. The
                  software integrates a wider selection of mapping symbols including oil and gas symbols with
                  a convenient method for the management and addition of mapping symbols by the MOSS/
                  MAP user. The result is an easy to use facility for the creation of maps of superior readability.
                  MOSS/MAPS Slope', Aspect Enhancement

                  GeoSpatial Solutions performed a number of software enhancements to the MOSS/MAP
                  software and used extensively by the U.S. Department of the Interior. These enhancements
                  were requested of GeoSpatial Solutions by the Department of the Interior Bureau of Land
                  Management because of GeoSpatial Solutions' extensive experience with this software and
                  a proven record of transforming resource information requirements to effective information
                  systems capabilities. One such enhancement includes modification of the MOSS/MAPS
                  slope/aspect function to provide several options for masking or interpolating missing or
                  invalid data.


                  DEM Arc-Second Import Command for MOSS/MAPS

                  GeoSpatial Solutions developed a command for the MOSS]MAPS package to permit transfer
                  and reformatting of 1:250,000-scale digital elevation models (arc-second Defense Mapping
                  Agency data) as supplied by the U.S. Geological Survey. The import command extracts
                  header information and converts the DEM-format data into standard MAPS cell files.


                  Projection-Change and Resampling Command for MOSS/MAPS

                  GeoSpatial Solutions built a MAPS command to allow conversion of MAPS cell files
                  between a variety of different map projections. Second-order transformations are created to
                  predict grid positions between input and output maps and one of several available resampling
                  techniques are used to fill the output map.

                 MOSS Point to Polygon Distance Determination

                 GeoSpatial Solutions recently completed the development of a new MOSS software
                 capability to permit the calculation of distances between point locations and polygonal areas.
                 This capability was previously unavailable to Department of the Interior agencies and was
                 required for a number of geological analyses.


                 PC/MOSS

                 GeoSpatial Solutions recently completed the conversion of elements of the MOSS software
                 system from the minicomputer environment to the Personal Computer environment for the
                 U.S. Department of the Interior. This new software development, in combination with
                 increased cost effectiveness of Personal Computer hardware for technical data processing,
                 will permit the use of Geographic Information Systems (GIS) technology by organizations
                 which previously could not afford such an approach to mapping needs.


                 Cartographic Output Systems Survey

                 GeoSpatial Solutions recently completed a comprehensive survey of computerized carto-
                 graphic output systems for the U.S. Department of the Interior Bureau of Land Management.
                 This survey investigated the software systems available and reported technical details of the
                 relative merits of the various systems to suit the needs of the Bureau. This effort provides
                 further evidence of GeoSpatial Solutions'leadership position in computer applications to the
                 mapping sciences. The performance of efforts proves beneficial to GeoSpatial Solutions'
                 goal of remaining well informed of the state-of-the-art.


                 Bureau of Indian Affairs On-Site Support

                 For several years, GeoSpatial Solutions provided full time on-site technical support to the
                 U.S. Department of the Interior Bureau of Indian Affairs Geographic Information Systems
                 and Remote Sensing Program. This program provides computerized mapping services
                 nation-wide to assist in the effective collection, assimilation, analyses, interpretation and
                 reporting of land use information. The role of GeoSpatial Solutions in this program ranged
                 from computerized mapping systems hardware and software support to specialized applica-
                 tions projects requiring a comprehensive understanding of a wide range of spatial data
                 handling techniques.

                 GeoSpatial Solutions was responsible for acquiring, installing and supporting the remote
                 sensing and GIS systems (ERDAS, ELAS and ARC/INFO) currently installed for the U.S.
                 Department of the Interior Bureau ofindian Affairs GIS activities. GeoSpatial Solutions staff
                 have attended ERDAS and ARC/INFO training and information sessions and fully under-
                 stand the operation, file structures and data transfer requirements of each system.


                 Custom GIS and Data Analysis Services for Arctic Sea-Ice Information

                 Unique applications often yield data sets that require specialized processing and services.
                 GeoSpatial Solutions has provided such services to Arctic Analysts, Inc. to analyze satellite
                 derived information on sea-ice in the Arctic. Tasks include specialized software to convert
                 data to ARC/INFO format and analysis in combination with satellite imagery.

                                          Prior to joining Chester Engineers, Dr. Shamsi worked on several
                                          research projects in the Civil and Industrial Engineering Depart-
                                          ments of the University of Pittsburgh. One civil engineering project
                                          studied the reliability approach to water supply infrastructure main-
                                          tenance and rehabilitation. It involved developing a mathematical
                                          model, based on the water supply at the demand points in a distribu-
                                          tion system. Computer software was developed to implement the
                                          proposed algorithm and some distribution systems were analyzed to
                                          show the application. This project resulted in Dr. Sharnsi's Ph.D.
                                          dissertation and four published papers.

                Responsibilities         Mr. McKee is a Project Engineer in Chester Engineers Planning and
                                         Studies Department. His responsibilities include the preparation of
                                         stormwater studies and regional solid waste management plans. He
                                         provides technical support for the review of developers' stormwater
                                         control facilities designs. SCS TR-55 hydrologic analysis tech-
                                         niques are used to quantify pre- and post-development stormwater
                                         runoff rates and appropriate release rate percentages are applied to
                                         identify specific stormwater control requirements. Hydrograph
                                         routing analyses are then performed to determine whether the pro-
                                         posed stormwater control facilities are appropriate. Both manual and
                                         computer based techniques are used for curve number weighting,
                                         hydrograph generation, hydrograph routing analyses, and basin
                                         outlet structure design.

                Experience               Mr. McKee's previous experience includes independent consulting
                                         work and five years of employment with amajor steel producer in the
                                         environmental monitoring field. Since joining Chester Engineers,
                                         Mr. McKee has participated in stormwater management activities,
                                         development review plans and the preparation of county-wide mu-
                                         nicipal solid waste management studies. He has also completed
                                         water and wastewater feasibility studies and other studies related to
                                         public facilities planning.
