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 Erie County 4026-01/6-91 streams and storm sewers, greatly increases the cost of public facilities to 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. II. WATERSHED CHARACTERISTICS 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 T@@@@ineers Erie County 2 4026-01/6-91 watershed is displayed in Figure 1. The watershed includes all streams and drainage areas (with the exception of those located in the Elk Creek and Conneaut Creek watersheds) which discharge into Lake Erie. These watersheds include the following streams which were identified in the Pilot Act 167 Plan and the Pennsylvania Department of Environmental Resources' Bulletin No. 5 Dams, Reservoirs and Natural Lakes: Bear Run Marshall Run Sixmile Creek Brandy Run McDonnel Run Sixteeninile Creek Cascade Creek Middle Run Trout Run Crooked Creek Mill Creek Turkey Creek Dewey Run Orchard Beach Run Twelvemile Creek Eightmile Creek Raccoon Creek Twentymile Creek Fivemile Creek Severimile Run Walnut Creek Fourmile Creek Wilkins Run The Lake Erie Watershed is contained in the following 21 municipalities in Erie County: Conneaut Township Lake City Borough Elk Creek Township Lawrence Park Township Erie City McKean Township Fairview Borough Millcreek Township Fairview Township North East Borough Girard Borough North East Township Girard Township Platea Borough Greene Township Springfield Township Greenfield Township Summit Township Harborcreek Township Venango Township Wesleyville Borough 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.

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: UNITED STATES GEOLOGICAL SURVEY STREAM GAGING STATIONS Drainage USGS ID Area Record Gage Name Number (sq. mi.) Period Raccoon Creek at W. Springfield 1304 2.53 October 1968 to present Brandy Run near Girard 13075 4.45 May 1986 to present Mill Creek at Erie 13200 9.16 1945 to present 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. T@@@@ineers Erie County 5 4026-01/6-91 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.

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 county soil surveys published by the U.S. Soil Conservation Service for Erie County in Pennsylvania, Ashtabula County in Ohio and Chautauqua County in New York. 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: T_L@@@ireers Erie County 7 4026-01/6-91 Brandy Run Goodban Run Lawson Run Elk Creek Halls Run Little Elk Creek Falk Run The Elk Creek Watershed is contained in the following 12 municipalities. Elk Creek Township McKean Borough Fairview Township McKean Township Franklin Township Platea Borough Girard Borough Summit Township Girard Township Washington Township 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. TreChesterEngiireeers Erie County 8 4026-01/6-91 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. 111. ACT 167 PLANNING FOR THE LAKE ERIE AND ELK CREEK 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 The@@@iineers Erie County 9 4026-01/6-91 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 Erie County 10 4026-01/6-91 City of Erie Millcreek Township Harborcreek Township Fairview Township Lawrence Park Township Wesleyville Borough Summit Township 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 Erie County 4026-01/6-91 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 floodplain management analysis, design and regulatory permitting efforts. Further, the stream encroachment permit process, which involves the need to sur fply detailed stream flow data as a part of the application process, can be more e ficiently 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.

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 questionnaire is included as Appendix A of this document.) Because the most important part of the Act 167 planning process is the actual implementation of the plan, another consideration in utilizing this questionnaire strategy for the Lake Erie and Elk Creek Watersheds is the interest by the responding municipalities for the need and the desire to actively implement Erie County 13 4026-01/6-91 stormwater management measures within their community. A summary of the stormwater related problems and the identification of properties affected by flooding incidences in each municipality is an important product of the Phase I study.

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.

Note: N/A = not available 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 The@@Jneers Erie County 16 4026-01/6-91 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.

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 Erie County 19 4026-01/6-91 adversely affect health, safety and property in other municipalities within the watershed and in basins to which the watershed is tributary; and 15. consideration for consistency with other existing municipal, county, regional and State environmental and land use plans. The concept and approach presented in the previous discussions has been organized into a set of the following detailed tasks. These tasks include the above indicated 15 elements of the plan. Task 1 - ProJect Initiation This task covers the administrative work required to initiate the Agreement between the Department of Environmental Resources (DEPARTMENT) and the County, and to initiate selection of a Consultant and, upon selection, to initiate contracts between the County and the Consultant and to lay out a framework for the critical coordination aspect with the municipalities. Activities include defining the framework for accomplishing various elements of the PLAN as described in Tasks 2 to 11, scheduling of time and defining the budget, progress reporting procedures and formats, and finalizing the work schedule. It will also include the preparation for and holding of the Phase 11 start-up meeting between the DEPARTMENT, Erie County and the selected consultant. Pro-ject Team Responsibilities Erie County Department of Planning -- responsible for overall administration of this task, including the finalizing of the Phase 11 Agreement with the DEPARTMENT and negotiating a contract with a consultant, the establishment of the project coordination roles and procedures, project scheduling and budget finalization, and the development of progress reporting procedures and formats. Consultant -- will perform a support role to the COUNTY and will attend all necessary project initiation and planning meetings. Consultant shall also finalize a detailed budget and schedule for technical and institutional planning. - Anticipated Task Product The anticipated product of this task will be a written summary of the notes and/or minutes of project initiation meetings. In addition, the finalized project work program, along with the associated budget and schedule, will be documented for review by the DEPARTMENT and for use as a project management guide. A project correspondence file will also be developed and organized and will be maintained throughout the total project duration. Task 2 - TLotect Coordination./Public Participation Through the Watershed Plan Adviso1y Committee Coordination efforts and/or activities will continue throughout the duration of the project and will be organized to include the necessary meetings with the County and consultant (anticipated to consist of one on-site progress and/or coordination meeting between the COUNTY and consultant per month for the duration of the project.) A WPAC was established in accordance with Section 6 of the Act. The TreChesterEngineers Erie County 20 4026-01/6-91 details of the WPAC including membership is included as Appendix D. Coordination efforts will also involve the reactivation of the Watershed Plan Advisory Committee (WPAQ, notification to the members of the WPAC concerning meetings, preparation of Agenda and attendance record at the VVTAC i Th WPAC membership list will consist of designated members from meetings. e each of the municipalities. The purpose of the WPAC meetings will be to initiate the im ortant and necessary municipal education process and data gathering efforts, including the preparation and distribution of the questionnaire for technical and institutional data. Additionally, the advisory role of the committee during the development of the plan is vital to the ultimate adoption and implementation processes. These meetings, being held at reasonable time intervals during Phase II, will promote the necessary involvement of the advisory group by contributing to the successful completion of this Act 167 effort in terms of the municipalities support and assistance in the adoption/implementation efforts. Included within the overall public participation program for the r ect will be the various education and t training meetings for the WPAC to mpaionj ain critical municipal involvement and understanding of the project. The following describes proposed WPAC and municipal training meetings and public hearing schedules including the purpose of each meeting.

Follow-up Intensive question and answer Meetings session anticipated. Project Team Responsibilities County will be responsible for the development of the coordination strategy for the overall project team (including documentation/ reporting responsibilities for the WPAC and DEPARTMENT). Also will be responsible for identifying and finalizing the WPAC members, as well as for the necessary arrangements to hold the WPAC meetings, and reproducing necessary material. Consultant - responsible for supporting the County in developing project coordination procedures and for providing f dance and input in the formation of the VVTAC. Responsible ouri the preparation of WPAC meeting agendas and technical presentations (including graphics). Anticipated Task Product The product of this task will include correspondence and meeting notes/minutes from the WPAC meetings. In addition, the presentation materials prepared for the WPAC meetings will also constitute a defined product of this project. Task 3 - Data Collection./Review./Analysis This task will involve the necessary efforts to gather, review and analyze the required data to complete the technical and institutional planning steps for the Lake Erie and Elk Creek Act 167 Watershed Storm Water Management Plan(s). The consultant and the county planning agencies will work jointly to collect data from county offices, municipalities, and local, state, and federal agencies that will aid in preparation of the PLAN. The data will consist of information concerning existing and future conditions in the watershed(s). All data collection activities will be limited to the gathering of available information from either the agencies that will be contacted or, more importantly, on the basis of the data collection questionnaire that will be provided to the municipalities (as well as selected agencies and organizations). The@@Jineers Erie County 23 4026-01/6-91 Data to be collected will include, but may not be limited to (and will be based on available information and/or questionnaire results): Comprehensive land use plans Existing Municipal ordinances Storm water related problems and proposed solutions Existing and proposed flood control projects Existing and proposed storm water control facilities Existing and proposed storm water collection and control facilities, including a designation of those areas to be served by storm water collection and control facilities within a 10-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 the identification of the existing or proposed institutional arrangements to implement and operate the facilities, where this information is readily available. Soils Geology Flow obstructions Topographic mapping High Altitude Aerial photographs Engineering and planning studies Stream flow data Floodplain information Water quality data Additionally, necessary field invest' t*0 s will be accomplished to gather an/or confirm the data. This task e rt will also coordinate closely with the start-up VVTAC meeting, which will involve the distribution of data questionnaires to the municipalities. In addition, a discussion of procedures to be followed in the completion of the questionnaires will be provided at the initial VVTAC meeting. This task also involves the review and preliminary analysis of the technical data that has been obtained for consistency and usability in the development of the final product -- i.e., the development of technical standards and criteria for storm water management. It also includes the review of the institutional data collected through the municipal data questionnaire process for R)e@@Jineers Erie County 24 4026-01/6-91 consistency and usability in the final implementation plan. The analysis will, however, involve the identification of initially missing data and verify the availability to gather the missing items. Floodplain information will be gathered for areas where detailed Flood Insurance Studies (F.I.S.) are available, with alternate sources being explored for stream sections that do not have detailed F.I.S.'s. Municipalities which have detailed control engineering plans for proposed remedial measures are available from municipality, County or private agencies. A summary analysis and evaluation of those plans will be included in the storm water management plan. Where detailed plans are not available, preliminary recommendations relating to such measures will be provided. Pro.ject Team Responsibili!y COUNTY - responsible for the distribution and initial training associated with the municipal data questionnaire. Consultant - responsible for assisting COUNTY with the preparation of municipal data questionnaires. Shall provide support for the actual data gathering and organizing efforts, as well as the preliminary review for consistency and content. Responsible for the review of gathered and organized data and the acceptability of the data, as well as for the preparation of a missing@ data list. Final responsibilities also include the final determination of data usability for the completion of the necessary technical and institutional planning efforts, as well as for providing input and/or alternatives for the collection of missing data. Anticipated Task Product The product of this task will essentially include the information listed above, gathered and organized in such a way as to be usable for both short- and long-term watershed planning (including u dates). A final 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 Erie County 25 4026-01/6-91 a part of the Act 167 watershed plan adoption process. Appendix B shows an example of a municipal ordinance matrix. Pro-ject Team Responsibilities COUNTY - responsible for providing insight and guidance to 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 TheChesWrEngiineers Erie County 26 4026-01/6-91 individually indicated on the base map for the purposes of future 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. Erie County 27 4026-01/6-91 significant obstructions and their capacities - where "significant" obstructions will be those that are identified in the municipal data questionnaires and which are confirmed by the consultant as being areas where insufficient capacity exists for the necessary storm flows. storm sewer systems - for significant system components: areas where storm sewering exists will be indicated generally on the final watershed base map. existing state, federal and local flood protection and storm water management facilities. proposed storm water facilities within the 10-year planning period - where known and confirmed by the municipalities through the municipal data questionnaire process. storm water related "problems" - where indicated in the municipal data questionnaire and where confirmed by technical modelin@/analysis (for example, water quality problems in the Lake Erie and Elk Creek Watersheds). Pro-ject Team Responsibilities @OUNTY - responsible for final review of technical mapping information prepared by the consultant and input into the delineation of future development areas. Consultant - responsible for review, analysis, and preparation of the catalogued municipal data questionnaire information to help identify the data, as described above, that will be included on the various maps. Also responsible for actual map and GIS preparation work described above and the development of watershed base maps for use in both the technical planning process as well as final plan presentation. Anticipated Task Product The product of this task will be the completed watershed maps for the information presented above. The maps completed for this task will, however, be preliminary mapping that can and/or will be modified and finalized as a part of the final plan preparation efforts. Task 6 - Model Selection and Model Set Up This task involves the selection and preparation of a hydrologic model appropriate for the analysis of the existing and projected land characteristics of the watershed. Technical input data required to run the model (in addition to land characteristics) will also be prepared such as rainfall information, drainage system layouts and capacities, travel times of subareas and information on man-made impoundments. TheClvnterEngireers Erie County 28 4026-01/6-91 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. Pro.ject Team Responsibilities COUNTY - responsible for general support of consultant's efforts in the model selection and development of the necessary model input data. Consultant - primary responsibility for the model selection and development and/or preparation of the model input data. Anticipated Task Product The product of this task will be a selected model along with the required hydrologic and hydraulic parameters for the Lake Erie and Elk Creek Watersheds. Task 7 - Basic Model Runs Model Calibration, Runs for Selected Frequengy Storms and Interpretation of Results This task utilizes the material prepared in Task 5 and organized in Task 6, in order to actually run the model and develop watershed-level storm runoff 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 TieChesWrB-gineers Erie County 29 4026-01/6-91 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. Erie County 30 4026-01/6-91 These recommendations will include storm water quality management components for the technical Standards and Criteria. These water quality provisions will then also be included in the ultimate municipal ordinance provisions for implementation. Pro-ject Team Responsibilities COUNTY - responsible for support of consultant in the technical activities. Consultant - responsible for the actual modeling and analysis/interpretation efforts to be conducted as a part of this task. Anticipated Task Product The product of this task will be the charts, tables and graphs developed to present the modeling results, and the technical interpretation of the modeling results. 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. Analysis of long term rainfall records, selection of a representative "typical" year from the standpoint of precipitation. Review of the literature and data developed locally followed by the selection of appropriate SWMM water quality input TreChester-E-gireers Erie County 31 4026-01/6-91 parameters for selected pollutants. The selection of pollutants to be modeled will be made based upon discussions with Planning Department and Conservation District personnel in consideration of the degree of concern related to potential pollutants and the existence of documented accumulation and wash off parameters suitable for use in the model. Assembly and running of the SWMM model for current, future "unmanaged" and future "best management practice controlled" conditions. Compilation, assembly and review of the findings of the modeling effort relative to the estimated impact of land development and the implementation of best management practices controls on annual non-point source pollutant loads generated within each watershed. Pro-ject Team Responsibilities COUNTY - responsible for support of consultant in the technical activities. Consultant - responsible for the actual modeling and analysis/interpretation efforts to be conducted as a part of this task. Anticipated Task Product The product of this task will be the charts, tables and graphs developed 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. The@@Jineers Erie County 32 4026-01/6-91 The standards and criteria will address the following: a. identification of all areas within the watershed where different criteria apply; b. recommended release rate percentages (if applicable) or other levels of control to accelerated runoff from the subareas identified in item a; C. recommended design flood frequencies and computational methodologies for storm water management measures; d. a list of recommended alternate storm water collection and 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. ProJect Team Responsibilities COUNTY - responsible for support in preparation of the technical standards and criteria. Also responsible for the detailed review of the standards and criteria project memorandum, and the submission to the consultant of questions and concerns for resolution prior to the completion of the final Act 167 plan (Task 11). Consultant - responsible for the actual technical evaluation/analysis to be completed for the development of technical standards and criteria as a part of this task. Anticipated Task Product The product of this task will be the definition of the technical standards and criteria used in the PLAN. TreChesterEngineers Erie County 33 4026-01/6-91 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. Pro-ject Team Responsibilities COUNTY - responsible for support of the consultant in the development and evaluation of institutional, legal and fiscal alternatives. An important role will be in the description of !ocal institutional capabilities and the delineation of future roles in storm water management activities. The County will have final responsibility tor the approval of model ordinance provisions for each municipality to be included in the final implementation plan for the watersheds. Consultant responsible for the completion of the ordinance review activities as part of this task. Also responsible for the development of the legal and financial alternatives for storm water management. Additional responsibilities exist for the evaluation and identification of intermunicipal arrangements for watershed level stormwater management in the watersheds. The consultant will also be responsible for providin& . the necessary coordination between selected ordinance provisions and the technical standards and criteria developed in Task 9. Anticipated Task Product The product of this task will be the identification of necessary recommended municipal ordinance provisions. REChesterEM'ineers Erie County 34 4026-01/6-91 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 will be listed according to the agency, municipality or individual responsible for each action. Priority for actions will be based upon ReCheaerEngiineers Erie County 35 4026-01/6-91 chronological order, importance, hydrologic significance or other appropriate factors. Also included will be a formal process of reviewing the storm drainage elements of subdivision plans against the performance standards of the PLAN, and the procedures for updating the PLAN at least every five years. The preliminary outline for the PLAN is as follows: Section I Introduction Section 11 Act 167 Watershed Level Storm Water Management Planning and Implementation Section III Watershed Characteristics Present Land Use Projected Land Developments Significant Obstructions Floodplain and Drainage Problems Storm Water and Flood Management Systems Section IV Watershed Technical Analysis - Modeling Land Development Impacts on Storm Runoff Expanded Non-Point Source Pollution Study Section V Technical Standards and Criteria for Control of Storm Water Runoff Modeling Results Interpretation Section VI Runoff Control Techniques and Their Efficiencies Section VII Existing Municipal Ordinance Information Section VIII Institutional Plan - Development of Model Storm Water Ordinance Provisions Section IX Priorities for Implementation of Technical Standards and Criteria Section X Plan Review Adoption and Updating Procedures PLATES: a base map showing the watershed delineation and political subdivisions, roadway network and the location as referenced to the County watershed subareas used for hydrologic analysis (including release rate percentage table, if applicable) stream obstructions, flooding and drainage problem areas, and streams for which 100-year floodplain information is available.

Also responsible for the preparation of project maps and the technical results tables and charts for presentation in the final PLAN document. Anticipated Task Product The product of this task will be final Lake Erie and Elk Creek Watershed PLAN(S). The final PLAN(S) will be prepared in two parts a Volume I -- Executive Summary and a Volume II -- a document containing the full text and descriptions of the various PLAN contents as described above. TheChesWrE@gireers Erie County 37 4026-01/6-91 Task 11 - Priorities for Implementation, PLAN Update, PLAN Adoption Priorities for Implementation The consultant will summarize the conclusions and recommendations of the PLAN. Recommended actions will be listed according to agency, municipality or individual responsible for each action. Priority of recommended actions will be based on chronological order, importance, hydrologic significance or other factors as may be appropriate. 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 Erie County 38 4026-01/6-91 vote of at least a majority of the members of the governing body, and should refer expressly to the maps, charts, textual matter and other materials intended 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 Commission regional planning agencies (Section 6 (c) of Act 167), public hearing notice and minutes (Section 8 (a) of Act 167), and the resolution of 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. 0 Pro-ject Team Responsibilities 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 and set update schedule with the help of COUNTY. 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 Erie County 39 4026-01/6-91 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.

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. VII. CONSULTANT CAPABILITIES The consultant who assisted with the preparation of this Act 167 Phase I plan was ne Chester Engineers.

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. 4 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 Exhibit B identifies the approximate locations of each of these watershed areas. 2 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. 3 m w Mao MWIMM mm m m LOCATION MAP OF THE LAKE ERIE AND ELK CREEK WATERSHED AREAS ......... ..... .......... . ... ..... ..... ............. . . . . . . . .. . . . ............. ...... .... co ...... . . ............ .. ........ .................... ..... ........... ... .......... fl CD EXHIBIT B ERIE COUNTY WATERSHED AREAS LAKE ERIE LAKE ERIE ELK CR.

In essence, ourproject managers function to focus the broad capabffities of Chester Engineers to meet the specific needs of our clients, direct the activities required to meet these needs and assure that our efforts accurately and fully respond to the client's wishes. 7291-01/3-91 1-5 \pm%Q-ESTRM1 STATEMENT OF QUAUFICATIONS AND E37ERZENCE FACILIMS AND EQUIPMENT The efforts of Chester Engineers' staff are supported and enhanced by the availability of a range of state of the art facilities and equipment. The capabilities provided by these facilities increase Cbester Engineers' ability to respond fully to the needs of our clients while maximizing the efficiency and accuracy of our efforts. Computer Facilities Chester Engineers' computer a capabilities include data analysis, system modeling and design applications. Computer facilities consist of a Hewlett-Packard HP-3000 Series central computer andnumerous peripheral and stand alone mck 4@4' microcomputer work stations. High speed and high resolution multicolor plotting facilities are capable of producing engineering flow diagrams, isopleth maps of surface and subsurface data, graphic statistical displays and a wide range of two dimensional and perspective graphics. An extensive library of scientific, engineering, graphics and statistical software has been amassed through in-house development efforts andthirdparty softwarepurchases. Specific software applicationpackages used by Chester Engineers' staff include pipe network analyses, surveying and property plotting, hydraulic and hydrological modeling and engineering analyses, and slope stability evaluations. The extensive utilization of computer assisted datamanagement, engineering analysis, and graphics and document production techniques by our personnel translates into a number of advantages to our clients. Our ability to analyze data is increased, the evaluation of larger numbers of options and what-if scenarios is facilitated and the visual effectiveness of our presentations enhanced, all with the added benefits of increased accuracy and efficiency. 7291-01/3-91 1-6 VmNQ-ESTRMI STATEMENT OF!2UAUFICATIONS AND EXPERJENCE Computer Aided Design/Engineering (CAD/E) The application of and benefits offered by the utilization of digital computer technologies extend beyond datamanagement and analysis and informationprocessing. Computer Aided Drafting and Design (CADD) capabilities have revolutionized 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 Microstation System, HP Series 48 central computer, Intergraph software, IIBM and Hewlett Packard micro- computers, multicolorplottmig facilities, interactive graphic terminals and a digitizing table. AF Through the use of Inroads 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 7291-01/3-91 1-7 \,pm\Q-ESTRM1 -STATENEW OF QUAUPICA77ONS AND EXPERIENCE 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. Sewer System Inspection and Monitoring Equipment Chester Environmental Group, through its wholly owned subsidiary Environmental Technical Services, Inc. (ETS), operates a fleet of sewer system inspection, maintenance and repair equipment and a complete inventory of sewer system flow monitoring equipment. This equipment is available for use as elements of sewer system, monitoring and evaluation programs conducted by Chester Engineers and provides us with ready and direct access to the sophisticated tools necessary to assess the condition of existing sewer systems and define appropriate remedial actions as warranted. Specialized sewer cleaning, inspection and repair equipment directly available to Chester Engineers through ETS include complete internal closed circuit television inspection units with internal grouting capabilities; sewer jets, cleaners, rodders and vactors; associated support vehicles; and related safety equipment. Monitoring of sewage flows is accomplished through the use of an inventory of flow measuring and recording equipment including Steven's and Manning depth recorders, flow velocity probes, and Marsh-McBirney flow depth and velocity measurement and recording 7291-01/3-91 1-8 \pm\Q-ESTRM1 STATEMENT OF QUAUFICATZONS AND EXPERIENCE devices.

The inventory of equipment operated by ETS includes Gurley open channel flow velocity meters, a full range of liquid level and flow measuring and recording equipment, automatic samplers and continuously recording precipitation gages. COMMITMENT EVIDENCED THROUGH 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 stormwater activities follows: U. S.

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. 7291-01/3-91 11-5 'j-\Q-ESrRNM -STATEMEW OF QUALWICATIONS AND EXPEJUENCE 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. 7291-01/3-91 H-6 '1-\Q-EsnM2 I I I I I I SECTION III Stormwater Management I Project Experience I I I I I I I I I I I I -STATEMENT OF QUALLPICA77ONS AND EXPERIENCE SECTION III STORMWATER MANAGEMENT PROJECT EXPERIENCE 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. 7291-01/3-91 V-\Q-E9rRM3 STATEMENT OF QUALLPICA77ONS AND EXPERIENCE 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.

The PhaseIScope ofStudy was approved by Allegheny and Westrnoreland counties and the Pennsylvania Department of Environmental Resources. 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. 7291-01/3-91 UI-2 \jp-\Q-ES7rRM3 -STATEMENT OF QUALIFICA77ONS AND EXPERIENCE 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. 7291-01/3-91 E11-3 -STATEMENT OF QUALOUCATIONS AND EXPERIENCE 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. 7291-01/3-91 M-4 \prn\Q-EYfRM3 -STATEMENT OF QUALIFICA77ONS AND E17EXIENCE PENNSYLVANIA ACT 167 STORMWATER MANAGEMENT PLANNING: 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. 7291-01/3-91 E11-5 -STATEMENT OF QUALLFICA77ONS AND EXPERIENCE 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. Turtle Creek Phase U Stormwater Management Plan Z. The Draft Turtle Creek Phase Il Stormwater Management Plan was completed in 1990. Digital satellite .... ...... imagery obtained from the Landsat Thematic Mapper and SPOT1 satellite and fiffiared photos from the NASA National High Altitude Pho- tography (NHAP) were used to de- lineate land cover classes in the wa- tershed. This information was com- bined with digital terrain informa- tion, digitized watershed boundaries and soil group locations in the ERDAS'm and ARC/INFO' geo- 7291-01/3@-91 E11-6 \-\Q-EsnW3 -STATEMENT OF QUALIFICA77ONS AND EXPERIENCE graphic information systems to produce the data set necessary to perform the required 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. Conneaut Outlet Phase H Stormwater Management Plan The Conneaut Outlet Phase II Stormwater Management Plan is currently under develop- ment. Monongahela River Phase H Stormwater Management Plan The Monongahela RiverPhase H Stormwater Management Plan is currently underdevelop- ment. Bull Run Phase U Stormwater Management Plan The Bull Run Phase II Stormwater Management Plan is currently under development. 7291-01/3-91 M-7 STATEMENT OF QUALLFICATFONS AND EXPERIENCE 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. 7291-01/3-91 111-8 -STATEMENT OF QUALIFICATIONS AND EXPERIENCE 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. 7291-01/3-91 M-9 \fm\Q-EMWM -STATEMENT OF QUALIPICA77ONS AND EXPERIENCE 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. to 7291-01/3-91 EEI-10 STATEMENT OF QUALIFICATIONS AND EXPERIENCE 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. 7291-01/3-91 N1-\Q-E9rP_W -STAMMENT OF QUALIFICA77ONS AND EJ7ERMNCE 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. 7291-01/3-91 111-12 -STATEMENT OF QUALLPICA77ONS AND EXPERIENCE 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. 7291-01/3-91 111-13 -STArEMENT OF QUALIFICA77ONS AND E27BRIENCE STORM SEWER DESIGN PROJECTS The Chester Engineers has a long history of successfully designing traditional storm sewer system. The following are descriptions of representative municipal storm sewer design 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 project services during construction and resident inspection. City of Huntington Storm Sewer Facilities The Chester Engineers was responsible for the design of this stormwater collection system project for the City of Huntington, West Virginia. This project consisted of. Construction of 72 inch main outfall sewers, including headwalls, sluice gates, sluice gate chambers, bridges, piers, other appurtenances and all work required for the removal and restoration of a concrete flood wall.

REPRESENTATIVE PROJECTS Thefollowing arebrief descriptionsof recentprojects conducted by the GeoSpatial Solutions Division of Chester Engineers. 7291-01/3-91 TV-1 \p-\Q-ESTRM4 -STATEMENT OPQUALIFICA77ONS AND EXPERIENCE 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. 7291-01/3-91 lV-2 -STATEMENT OF QUALEFICA77ONS AND E"ERIENCE 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. 7291-01/'-'91 IV-3 \fm\Q-ES`rRM4 -STATEMENT OF QUALIFICA77ONS AND E"ERIENCE 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. 7291-01/3-91 IV-4 \pn\Q-ESTRM4 -STATEMENT OF QUALIFICA77ONS AND EXPERIENCE 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. 7291-01/3-91 IV-5 -STATEMENT OF QUALIFICA77ONS AND EXPERIENCE 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.
