- Description
- NA The U.S. Army Corps of Engineers will be issuing a invitation for Bid for theTown Pond Restoration, Portsmouth, Rhode Island. Town Pond is located in Portsmouth, Rhode Island adjacent to Mount Hope Bay. The modern historical condition of the Town Pond are a was tidally influenced open water prior to a Corps navigation improvement project placing dredged material in the area in the early 1950s. At that time, tidal exchange to the interior marsh was effectively halted. The Town Pond Restoration Project calls for a combination of fifty-percent salt marsh-fifty percent open water/intertidal habitats with on-site disposal of excavated material. This was selected as the best overall plan for habitat restoration, aesthetic acceptability and affordability. An est imated 126,000 cubic yards of existing dredged material would be excavated to promote restored tidal exchange to Town Pond. Over time, the interior marsh will be transformed from a lower value brackish habitat to a high value salt pond and salt marsh habi tat. The excavation and regrading of the area to reach the new profile will require the establishment of an effective plan for control and diversion of water. There will be some vegetation removal in the staging and access areas (approximately 1 to 2 acr es of upland vegetation and asphalt at the southeastern end of the site off Anthony Road) on the Roger Williams College property. The size of disturbance of the staging area, access roads and temporary haul roads will be limited to the minimum necessary f or construction access and a line of erosion control devices will be established along the perimeter. Temporary haul roads will be removed following their use and these and other areas will be allowed to revegetate following construction. Areas with seve re slopes or disturbed soils with a high potential to affect water quality will be replanted to limit erosion. A small area of salt marsh (approximately 80 square feet) will be destroyed to deepen and realign the entrance channel inlet. Salt marsh plants will be removed by others prior to construction and planted along the new channel alignment to reestablish a salt marsh cordgrass fringe resulting in no net change in wetland area. Approximately 18 acres of phragmites, which is above the elevation of tida l influence, will be removed to restore salt marsh and estuarine habitat. Once elevations are established that are flooded by frequent tides estuarine habitats and vegetation communities will establish. There are two concrete structures that will be built as part of the project. A 45-foot long, 42-inch diameter culvert with concrete headwalls will replace a smaller old culvert that will be removed and a concrete weir approximately 38 feet long will be built to regulate a permanent pool where the entrance channel meets the interior marsh. The plan requires some phragmites wetland filling to construct a water control berm along the west side of the site to prevent flooding of Founder??????s Brook by salt water. The water control berm would fill approximat ely 3.2 acres of wetland and the public access area would fill approximately 0.35 acre of wetland. The berm would be seeded with coastal grass and shrubs would be planted at occasional intervals along the top. Some excavated material would be used to con struct a 6,750 square foot parking area with an entrance off of Anthony Road. Restoration plan has on-site disposal of excavated material in phragmites wetlands. The plan would require 7 acres of wetland fill. The disposal area will be seeded with coast al grasses (e.g. switchgrass) after construction is complete to create a coastal grass community. During the construction phase, there will be provisions to allow continued maintenance access to the existing electric transmission lines that run through the project area. THIS SOLICITATION IS UNRESTRICTED. Solicitation shall be made available via the Internet on or about 8/13/03. No paper copies of the solicitat ion or amendments will be available.
