                                            SUMMARY




                 Poquoson at this time has no major drainage problems such as

            are faced by most cities because of several factions; division of

            the City into small watersheds (excepting the Big Woods), low intensity

            of development and flat topography. The small watersheds limit the

            amount of runoff that is concentrated at any one point. The low density

            of development provides more surface for absorption of rainfall.

            The flat topography causes a slow rate of runoff providing more time

            for absorption, a high time of concentration, and a large-area

            for retention for each increment of water level rise. Although there

            is at times rain water standing longer than residents might wish

            very little damage to property results from meteoric water. Tidal

            flooding is the biggest cause of flooding damage.

                 To provide adequate outfalls together with adequate access easements

            for all areas would require an estimated $637,445.00 (see pages BC-6

            and C-1). In the fully developed areas $408,035.00 would necessarily

            be borne by the City alone. In the undeveloped areas significant

            shares of the cost could be borne by the developers.

                 Drainage requirements of the Big Woods have not changed significantly

            since 1986. The existing system is adequate for the present state

            of development. Further development will require improving the capacity

            of the system most likely by a storm water detention or retention

            system either by a public body or piecemeal as individual parcels

            are developed.












                                          INTRODUCTION




                 This study was authorized by the City Council resolution dated

            October 28, 1991 and is paid for in part (50%) under a grant from
            the Virginia Coastal Resobrces Management Program (VCRMP). The purpose

            is to update and expand the existing Master Drainage Plan. The original

            Master Drainage Plan which covered approximately 30% of Poquoson

            was prepared in 1975 and was supplemented in 1986 by the Big Woods

            Drainage Study and later by studies of other watersheds (Odd Road,

            Little Florida Road, etc.).   With this study all drainage systems

            have been inventoried and all major systems have been analyzed and

            preliminary improvement designs made where needed.



                                          METHODOLOGY




                 This study has two principal parts: First, an Update Inventory

            of Structures and Improvements. This part consists of city-wide

            location and identification of all drainage structures (pipes, culverts,

            .nlets, etc.) and ditches. Functionality or dysfunctionality and

            physical condition is noted where feasible. The topography sheets

            prepared by Air Survey & Design, Inc. in 1985 are the base sheets

            for this study. The Update Inventory information includes all the

            base sheets. The Proposed Systems include only those sheets where

            new proposals are located.

                 All elements in the existing systems were visited by field personnel;

            dimensions were measured and elevations taken. Insofar as practical,

            conditions of the structures were noted. However, in many instances

            the blockages and/or siltation made exposure of the structures impractical

            for personnel access without excavation equipment. In a few cases

            access to private property for purpose of this study was denied by

            the property owner despite appeals by the City staff.

                 There are some structures in the City that no longer function

            as originally intended because of subsequent development and improvements.

            Pipes have been abandoned in place and ditches have become clogged

            with vegetation and/or silt.

                 The second part of the study is the Proposed Drainage Systems

            which includes all significant watersheds not included in the 1975

            study or otherwise fully developed.

                 The principal design assumption is that undeveloped areas will

            be developed in accordance with current zoning except the Big Woods

            area. Development of the Big Woods was assumed to be according to

            the Zuchelli-Hunter study of 1985. However, using current zoning

            would not materially affect the results. Design calculations for

            all areas were made by the Rational Method again except for the Big

            Woods area in which SCS methods were used.

                 No attempt was made to design the drainage in undeveloped areas

            since there is no way to anticipate the timing or configuration of

            such development. Rather, the structures designed are where the

            outfall from present or future developed areas cross City Rights-of-Way







                                               3









            and the ditches designed are the outfall from these structures.

            These designs should serve to indicate to the City the outfall requirements

            when developments are proposed or when replacement of existing structures

            is necessary for whatever reason. In several locations two or more

            watersheds or parts of watersheds could conceivably be combined depending

            upon the sequence of development.

                 Costs from the proposals in this study have been tabulated and

            the costs from the 1975 and 1986 studies have been updated to current

            prices.  Eliminated from these costs are the access roads proposed

            in the 1975 study since this idea had apparently not found any acceptance.

                 On pages BC-1 through BC-5 costs for improvements proposed in

            this study are tabulated. Included in these costs are some items

            which are not necessary to drain City Rights-of-Way but which would

            be necessary for development of an upstream area. In undeveloped

            areas creation of on-site detention or retention ponds may be an

            option for private citizens. This would not generally be an option

            for the City due to space requirements.

                 On pages C-1 and BC-5 are summarized the costs from the 1975-1986

            and 1992 studies respectively which have been adjusted to subtract

            any on-site costs which might be for private development. Nevertheless,

            any improvements in public right-of-way or outfall are sized to accommodate
            up-stream development.  ENVIRONMENTAL CONCERNS


                 Environmental requirements effecting improvements such as proposed







                                               4









            in this report are addressed by the following applicable ordinances:

                 Site Plan Ordinance

                 Subdivision Ordinance

                 Erosion and Sedimentation Control Ordinance, Sect. 2.3(4)

                 Chesapeake Bay Preservation Ordinance

                 Each of these ordinances incorporates requirements for storm

            water management with the Chesapeake Bay Preservation Ordinance Overlay

            overriding most other requirements. No additional legislation would

            be required at this time.



                                           BIG WOODS



                 The drainage for the Big Woods is adequate for the area as now

            developed (9%ï¿½) but has very little excess capacity. The 1986 study

            estimated a cost of close to $3,000,000.00 to purchase the land and

            construct the combination of ditches and detention ponds that would

            be required for full development as envisioned by the Zuchelli-Hunter

            study. Future development without greatly enlarging the present

            system could require on-site detention by each individual development.

            At the time of the 1975 drainage study the Big Woods basin was estimated

            at 467 acres. Approximately 121 acres was added to the system with

            the extension of a ditch to Cary's Chapel Road in York County. The

            1986 study assumed the inclusion of additional acreage as covered

            by the Zuchelli-Hunter development study giving a total of about

            665 acres. Two subsequent development projects; Wythe Creek Plaza







                                              5









            Shopping Center and Bayside Convalescent Center have had some small

            effect on the basin. Wythe Creek Plaza increased the rate of runoff

            in the area developed (5 acres) but mitigated the effect on the system

            by enlargement of the north side ditch on Victory Boulevard and installation

            of an additional 36" pipe across Victory Boulevard.

                 The drainage t,ystem constructed for Bayside Convalescent Center

            probably has the long term effect of diverting about 16 acres from

            the Big Woods system.

                                 BASIN "A" - NORTH PASTURE ROAD
                                             SHEET 2



                 Basin "A" takes in a total  of 18.4 Ac.ï¿½ of largely undeveloped
            land, 14 Ac. from west of Pasture Road through an existing 15" culvert
            under Pasture Road and through a ditch to Lyons Creek.

                 The existing 15" pipe is inadequate for a developed basin due
            to its lack of capacity and elevation to extend its reach to the
            upper portions of the basin.

                 Proposed improvements would consist of replacing the 15" pipe
            with a 30" RCP across Pasture Road into a manhole, then 2 runs of
            36" RCP to a point past the garage on the adjoining property. From
            the pipe, regrade and reshape 260'-+ of existing ditch at B=4, Z=l
            to a cove of Lyons Creek.

                 An existing 10' easement runs down the south side of the existing
            ditch. An additional 10' strip should be acquired on the north side
            until the end of the pipe, then a 15' strip additional on the north
            side down to the cove.

                 Estimated Cost of Improvements - $18,614.00





                                 BASIN "B" - NORTH DARDEN DRIVE
                                            SHEET 4




                 Basin "B" covers 15.6 Ac.ï¿½ with 75% being undeveloped land.
            Current drainage is through a ditch on the east side of Emmaus Road
            into a 24" piping system, crossing Emmaus Road, which discharges
            into a paved ditch which flows into Lambs Creek.

                 Development in the upstream basin would require replacing the
            existing 24" system with a 27" system. The outfall ditch into Lambs
            Creek is adequate and will require no improvements other than to
            remove a section of 24" pipe at the extreme downstream end. Both
            the ditch and piping system are covered by easements and no additional
            easements are required.

                 Estimated Cost of Improvements - $16,972.00

                 Alternative - As an alternative drainage system, all the area
            east of Emmaus Road in the north and south Darden Drive and Freemoor
            Drive basins could be combined and drained through only one outfall.

                                  BASIN "C" - SOUTH DARDEN DRIVE
                                              SHEET 4



                 Basin "C" is comprised of 16.2 Ac. approximately half of which
            is undeveloped land. Runoff is carried through a ditch into a piping
            system crossing Emmaus Road into a paved ditch leading into Lambs
            Creek.

                 The existing piping system is inadequate to handle increased
            flows from a developed basin. The existing 18" and 24" system should
            be replaced with a 27" and 30" system. The existing paved outfall
            ditch is adequate and no improvements are proposed.

                 The outfall ditch is covered by a 20' easement   and the first
            run of pipe on the east side of Emmaus Road is covered by a 10' easement.
            The 10' easement should be increased to 15' and a 15' easement should
            be acquired to cover the remainder of the piping system.

                 Estimated Cost of Improvements - $30,058.00

                 Alternative - As an alternative drainage system, all the area
            east of Emmaus Road in the north and south Darden Drive and Freemoor
            Drive basins could be combined and drained through only one outfall.





                                   BASIN "D" - FREEMOOR DRIVE
                                               SHEET 4



                 Basin "D" encompasses 20.4 Ac. approximately   half of which is
            developed. Existing drainage consists of a ditch    on the east side
            of Emmaus Road, draining to a yard drain with 18"   pipe. The yard
            drain drains to a 18" culvert under Emmaus Road into a ditch at the
            rear of Freemoor Estates. Runoff then enters a 24" piping system
            across Freemoor Drive and into a branch of Lambs Creek.

                 For total development in this basin the existing system is inadequate.
            The 18" system should be replaced with a 24" and 27" system crossing
            Emmaus Road. The proposed system is lowered to provide reach into
            the upper basin. The existing ditch beside Freemoor Estates should
            be regraded to match the inverts between the piping systems. The
            2411 piping system across Freemoor Drive should be replaced with a
            301' and 36" system.











                                                B-2






                   An existing 10' easement covers the pipe and ditch at Freemoor
             Estates. There is no easement for drainage on the east side of Emmaus
             Road. An additional 10' easement would be required for the ditch
             for maintenance and 15' easements for the piping system east of Emmaus
             Road.

                   Estimated Cost of Improvements - $44,039.00

                   Alternative - As an alternative drainage system, all the area
             east of Emmaus Road in the north and South Darden Drive and Freemoor
             Drive basins could be combined and drained through only one outfall.





                                    BASIN "E"     SOUTH EMMAUS ROAD
                                                  SHEET 4



                   Basin-"E" covers an area of 36.9 Ac.ï¿½ of private, largely undeveloped
             land with 7.6 Ac. north of Emmaus Road draining through an 18" culvert
             under Emmaus Road and into an outfall ditch to Lambs Creek.

                   In a developed state, the 18" culvert under Emmaus Road is inadequate
             to carry the runoff. Proposed improvements would include replacing
             the 18" pipe with a 19"x3O" culvert, lowered enough to provide the
             reach for the upper areas of the basin and to provide cover for the
             pipe.

                   The outfall ditch would require regrading and reshaping to B=2,
             Z=l at .0035 ft/ft. A 25' drainage and maintenance easement would
             be required from the Emmaus Road culvert to the end of the outfall
             ditch.

                   Estimated Cost of Improvements - $31,275.00






                                   BASIN "F" - NORTH POWHATAN DRIVE
                                               SHEET 8



                   Basin "F" encompasses 47.4 Ac.ï¿½ of private land, a majority
             of which is undeveloped. Runoff drains through a ditch at the north
             side of Westover Shores/Powhatan Place subdivision and into a 24"
             piping system across the front of the pumping station at the end
             of Westover Drive and into an arm of Lambs Creek.

                   In order to convey runoff from a fully developed basin, the
             24" pipes would have to be replaced with 42" pipes at least as far
             as the current piping system. Upstream improvements might include



                                                     B-3






           an extended piping system or a drainage ditch (B=2, Z=1) to some
           point in the upper reaches of the basin.

                 There is an existing 15' easement along Powhatan Place and Westover
           Shores but any additional easement requirements will have to be determined
           based on the future drainage design.
                 Estimated Cost of Improvements - $8067.00





                                BASIN "G"   SOUTH YORKTOWN ROAD
                                            SHEET 8



                 Basin "G" consists of 15.8 Ac. of mos tly undeveloped land.
           Runoff from 7.9 Ac. east of Yorktown Road is carried through a 24"
           culvert into a drainage ditch that connects to the Westover Shores
           ditch.

                 With the development of Bayside Convalescent Center, a large
           portion of the area that previously drained to the 24" culvert was
           diverted to the Westover ditch through Bayside's drainage system.
           The 24" culvert is adequate to handle the flow from the remainder
           of the basin, however 950' of ditch from the culvert to the Westover
           ditch should be cleaned, widened, and regraded. A 20' easement is
           required.
                 Estimated Cost of Improvements - $15,086.00






                               BASIN "H" - NORTH ROBERTS ACRES
                                            SHEET 5



                 Basin "H" is comprised of 30.8 Ac.ï¿½ of which 2/3 is already
           developed (Roberts Acres). The basin is drained through a ditch
           on the north side of Roberts Acres into a 30" culvert across Hunts
           Neck Road and out into Roberts Creek. To accomodate increased flows
           from the remainder of this basin being developed would require the
           replacement of the 30" culvert with a 36" culvert at the same grade
           and elevation or reinforcing the existing culvert with a 21" pipe.

                 The existing outfall ditch to Roberts Creek is adequate for
           increased flows but rip-rap is required at the outfall pipe.







                                                B-4






                 A variable width draiange easement is in existence on the Roberts
            Landing side of the outfall ditch. An additional 15' easement is
            required on the east side of Roberts Landing down to Roberts Creek.

                 Estimated Cost of Improvements - $7,022.00





                                BASIN "I" - SOUTH ROBERTS ACRES
                                            SHEET 5



                 Basin "I" encompasses an area of 56.5 Ac.ï¿½, of which approximately
            half is undeveloped land. The runoff from this basin currently
            flows through a ditch running along the south side of Roberts Acres,
            through a 24"x53" pipe across Hunts Neck Road and through a ditch
            into Roberts Creek.

                 The 24"x53" pipe at Hunts Neck Road is inadequate to handle
            the runoff from a totally developed basin. Improvements would necessitate
            replacement of the existing pipe with a 38"x6O" HERCP, lowered enough
            to give cover and not conflict with the existing sanitary sewer.
            The outfall ditch northeast of Hunts Neck Road requires regrading
            and widening from the 38"x6O" to Roberts Creek.

                 A 25' easement is required for drainage and maintenance on the
            outfall ditch.

                 Estimated Cost of Improvements - $24,386.00





                            BASIN "J" - WAINWRIGHT DRIVE EXTENSION
                                       SHEET 9



                 Basin "J" encompasses 24.6 Ac. of largely undeveloped land to
            the southwest of Poquoson Avenue and northwest of Hudgins Road.
            Current drainage is by way of a small ditch running from Islander
            Way to a 24" piping system crossing Poquoson Avenue and out to a
            canal into White House Cove.

                 Development in this basin would require replacing the existing
            piping with a 29"x45" pipe across Poquoson Avenue lowered to provide
            cover, then a 36" outfall pipe to the canal.

                 The outfall pipe to the canal is currently without an easement
            and will require a 15' easement.

                 Estimated Cost of Improvements - $17,057.00

                                   BASIN "K" - ALPHUS STREET
                                               SHEET 14



                 Basin "K" totals 36.5 Ac.ï¿½ currently draining from Little Florida
            Road south to Alphus Road, through a 24" culvert then through a ditch
            south to Oxford Run.

                 The Alphus Road system was previously studied in 1975, but since
            then drainage installed in the Poquoson Shoppping Center and by VDOT
            have eliminated the need for any drainage to cross Little Florida
            Road.


                 In order to drain sections of Little Florida Road between Smith
            Street and Wythe Creek Road, an existing ditch running to Alphus
            Street would require lowering and reshaping at B=l, Z=l, then a piping
            system as shown on the previous study, with the exception of 36"
            pipe in place of 48" pipe would be required to cross Alphus Road.
            The outfall ditch from Alphus Street to Oxford Run would require
            regrading and widening to B=4, Z=l. A 25' easement would be required
            the length of the proposed ditches for drainage and maintenance.
                 Estimated Cost of Improvements - $55,833.00





                          BASIN "L" - CEDAR ROAD/LITTLE FLORIDA ROAD
                                      SHEET-15



                 Basin "L" encompasses an area of 74 Ac.ï¿½ which presently drains
            across Little Florida Road from the north through an 18" RCP and
            a 12" RCP, southward to dual 24" RCPs under Cedar Road.

                 Development in this area would require the replacement of the
            dual 24" RCPs at the outfall with a single 54" RCP and lowering the
            invert in order to reach the upper limits of this basin. The existing
            drainage ditch along the first 650'+- upstream of Cedar Road is adequate
            but would need to be deepened. There are 2-36" RCPs along this route
            that need to be lowered to increase reach. Enlarging the existing
            ditch section would be required from these pipes northward to Little
            Florida Road where the 18" RCP would be replaced by a 36" RCP and
            the 12" RCP would be replaced by an 18" RCP. The sanitary sewer
            at Cedar Road is deep and does not present a problem. There is an
            18 sanitary sewer force main along Little Florida Road which may
            need relocation below the proposed 36" RCP.

                 Waterlines along both routes may need adjustment to allow for
            increased pipe sizes.

                 A 25' easement along the ditch north of the dual 36" pipes and
            a 40' easement along the ditch south of the pipes is recommended.

                  Estimated Cost of Improvements - $88,880.00

                  Alternative - Development in Basins   1IM11 and "L" lend themselves
            to a  number of alternative drainage configurations. The area of
            Basin "L" north of Little Florida Road could be drained along Little
            Florida Road westward to the ditch at Far Street. The upper portion
            of Basin "M" could be combined with the lower portion of Basin "L"
            and drained southward to the existing large canal at Cedar Road.





                                            BASIN "M" - CEDAR ROAD
                                                        SHEET 15




                  Basin "M" drains a 30 acre watershed of undeveloped land which
            presently drains across Cedar Road in a single 18" pipe. This pipe
            is inadequate even for the present drainage situation. Replacement
            of the 18" RCP with 2-36" RCPs and lowering the invert is proposed.
            Regrading of approximately 200' of outfall ditch to the west of Cedar
            Road is required.

                  Existing sanitary sewer at this location limits the use of a
            single larger pipe. Installation of the 36" pipe will require an
            increase in the height of the road to provide sufficient cover over
            the pipes. Use of HERCP pipe could reduce this requirement.

                  A 4" sanitary sewer force main relocation under the 36" pipe
            would be necessary as would any existing waterlines.

                  A 25' easement along the outfall ditch is recommended for proper
            maintenance.

                  Estimated Cost of Improvements - $18,570.00

                  Alternative - Rerouting of runoff from Basin "M" into Basin
            "L" and southwest to Cedar Road would reduce the requirements at
            this location.
