7:50 PM Town of Plymouth, DPW, Billington Street and off Billington Street, Parcel ID No. 027-000-127-000 and 027-000-129-000. A Notice of Intent for the removal of the Plympco Dam and associated amenities, including grading, plantings and channel daylighting and channel restoration for fish-way improvement within the resource of Town Brook. (Complete project narrative available in the Conservation Office.)
David Gould, Environmental Manager and Acting DPW Director presented the project. Also present was consultant Elsa Loehmann of Milone and MacBroom and Nick Wildman, Mass Fish and Game-Division of Ecological Restoration.
Mr. Gould gave some background noting that it has been in the works for several years with several project partners
Project involves Town Brook and the removal of 2 dams.
Elsa Loehmann of Milone and MacBroom continued with the presentation:
Two impoundments are present and are slowly filling with sediment and are aggraded. Fish habitat needs to be restored in this area. Cool water stream will be created to create habitat for cool water fish.
New bridges are designed for plenty of habitat crossing. Free flowing cool water stream will be created to support the cool-water species such as trout rather than the warmer water bass and pumpkin seed that exist there now. Aside from the dam removal, daylighting will occur in a section of the stream. The 140 ft. long culvert under the existing factory building will be abandoned and the channel will be brought out to expose to daylight to aide the fish passage.
Structural and site amenities will include replacement of the two access bridges. Repavement sections of the road and utility improvements. Curbing will be added and stormwater runoff will be collected. Catch basins will be added in different areas.
Wetlands on site were described as emergent marsh wetlands and Ms.Loehman went on to describe the wetlands. She noted that the wetlands could not exist without the dams. They support warm water habitat which they would not do so naturally, but they are warm due to the sediment filling. Increase of wetland areas will be achieved upon completion of the project – totaling 20,000 sq. feet as compared to14,000 currently. Higher quality wetlands will be achieved also.
Construction sequence: Water levels can be started to drop in February to commence a dry out of the sediment, phased water drawdown will occur a few inches at a time, to incrementally move down the impoundment. 15-20 cfs. of water will travel down the impoundment during the drawdown time.
Channel excavation will occur after water is down. Minimal bank grading is proposed, reached from the access road. Sediments removed from the channel will be taken off-site to the South Street landfill and used in other projects. 2 access drives will be open at all times and one easement was granted by and through the Tong property. Ongoing excavation, planting and grading will occur. Total time is approx. 4-6 months.
Plymco bridge area will be done first then the off-Billington bridge second (which will capture the sediment from the first area).
Nick Wildman, Div. of Ecological Restoration – timeframe after fish spawning was June 15 and run for 6 months.
Sediment testing evaluation showed some Chromium and arsenic
401 water quality and ACOE permit.
