                                                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.

                     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.

                                                   2

                     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%�) 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.

                                                  6

                                     BASIN "A" - NORTH PASTURE ROAD
                                                 SHEET 2

                     Basin "A" takes in a total  of 18.4 Ac.� 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.� 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.

                                                   B-1

                                      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.� 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.� 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.� 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

                                    BASIN "I" - SOUTH ROBERTS ACRES
                                                SHEET 5

                     Basin "I" encompasses an area of 56.5 Ac.�, 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.� 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.� 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.

                                                    P-6

                      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.
