Ellisville Harbor Inlet Stabilization Study
The Town of Plymouth received funding assistance through the FY17 Coastal Community Resilience Grant Program to develop alternatives to providing a more sustainable tidal inlet system servicing the Ellisville Harbor and Marsh estuary. Following inlet relocation in 2003 that involved breaching of the accreted barrier beach spit, the spit building process has continued and this elongation of the barrier beach has caused additional tidal attenuation that adversely impacts the salt marsh system. To allow for a more stable inlet system, the proposed project intends to perform a more in-depth alternatives analysis of potential structural and non-structural measures that can be utilized to maximize both the health of the salt marsh resources and provide a more consistent supply of sediments to downdrift beaches. The proposed project intends to build on the substantial historical data set available for the Ellisville Harbor system, including the results of ongoing monitoring. In addition, the assessment will consist of appropriate coastal processes modeling tools to determine effects of various inlet stabilization techniques. On-going threats to the marsh system, as well as to the built environment south of the marsh, are concerns for the Town as both long-term coastal erosion and relative sea-level rise in the coming decades will continue to exacerbate storm damage.
Public Meeting: An Informational Public Meeting was held onThursday evening May 25th 7pm at the Wildlands Trust Facility 675 Long Pond Road, Plymouth. The meeting provided information from the Consultant and project partners on several alternatives for stabilizing the Ellisville Harbor Inlet.
Great Herring Pond Stormwater
Eagle Hill Drive Priority Sites Stormwater Assessment
Design Completed, Construction Fall/Winter 2017-2018
- The contractor will be completing the last major area week of 10/16 between #7 and #9 Eagle Hill. We will make all attempts to keep one lane open but will not know whether this is possible until construction in the area begins.
- For any road closures - The road will be closed during construction 8am-3pm Mon-Fri. The road will be open during emergencies, in the evening (after 3:30pm) and on the weekends.
The objective of this project is to assess stormwater retrofit options and design the selected suite of best management practices (BMPs) to treat and infiltrate stormwater to the maximum extent in the vicinity of Eagle Hill Drive. A stormwater water quality assessment was completed in 2015 (download below) which indicated the two sites on Eagle Hill Drive as having the greatest impact on water quality. Currently, untreated stormwater discharges to Great Herring Pond via two outfalls on Eagle Hill Drive. Suspended sediment, nutrients, pathogens, hydrocarbons, and other contaminants associated with the runoff negatively impact water quality in the Pond and, as a result, the active herring run between the Pond and the Cape Cod Canal. Great Herring Pond water quality data was assessed in 2014 by the School of Marine Science and Technology and was found impaired when compared to MassDEP and regional standards. The surface water quality impairment is due to limited clarity, high nutrient levels and low dissolved oxygen. This project seeks to improve water quality in Great Herring Pond to protect the viability of the active herring run as well as provide a recreational resource to residents.
In early spring, the Town will hold a public informational meeting regarding conceptual design, design elements and obtain feedback from residents.
Public Informational Meeting: Was held on Wednesday May 3rd at 6pm, New Testament Church at 1120 Long Pond Road
Stormwater Assessment - Completed
The Department of Marine & Environmental Affairs partnered with the Herring Ponds Watershed Association and the School of Marine Science and Technology to complete an intensive stormwater assessment for 6 outfall sites that discharge to Great Herring Pond. With this information the Town will be able to apply for grant opportunities for implementation of stormwater improvements. In addition, the stormwater assessment will be included in the future watershed assessment for this area. Click here to download the Technical Memorandum and Findings.
161 Taylor Avenue Demolition
The Department of Marine & Environmental Affairs is working with the Community Preservation Committee on the demolition of the two cottages at 161 Taylor Avenue. The Environmental Site Assessment has been completed. The hazardous material removal and demolition is expected to start the week of October 5th and be completed in October 2015. DMEA will plant beach grass during the planting season March 2016. The Beach plum plantings will be installed early spring 2016 to ensure plant stability. The Community Preservation Committee will be installing the bollards in 2016.
54 Taylor Avenue Demolition
Demolition Completed April 2015
The Department of Marine & Environmental Affairs worked with the Community Preservation Committee on the Environmental Assessment and demolition of the structure at 54 Taylor Avenue. The Community Preservation Committee is currently working on re-development, a bath-house, for the site.
Plymouth Ponds and Lakes Stewardship Project
The Town of Plymouth Department of Marine and Environmental Affairs received $38,854 in grant funding from the Massachusetts Environmental Trust. This funding enable’s the Town and Project Partner UMASS Dartmouth - School of Marine Science and Technology (SMAST) to commence the Plymouth Ponds and Lakes Stewardship Program (PALS) and Pond Atlas for water quality analysis and reporting in 39 ponds throughout Plymouth.
The Plymouth Ponds and Lakes Stewardship Atlas June 2015 is now available - Download PALS Atlas. Note revisions made from May 2015 for snapshots for Little Long Pond, Gallows Pond, Halfway Pond and Bloody Pond. Click here to download the The Quality Assurance Project Plan.
In 2015 the following ponds are slated to be sampled and added to the Atlas: Little Sandy Pond, Lout Pond, Cooks Pond, Great Island Pond, Honeypot Lake, Island Pond (near Great Herring), Triangle Pond. Are you interested in volunteering? Please contact Kim Tower. Volunteers may download field data sheets for collection of temperature, dissolved oxygen and secchi disk.
Stephens Field Environmental Assessment - Demolition and Soil Excavation
Awaiting additional funding
The Department of Marine & Environmental Affairs led the Stephens Field Environmental Site Assessment conducted by a Licensed Site Professional. During the assessment an Underground Fuel Tank from prior owner was discovered. In November 2012, the tank was professionally removed and properly disposed. The Demolition work was completed in March 2014. The Soil Excavation started in April 2014, however, additional funding is needed to complete the soil excavaton and removal. This will be completed prior to the park renovations.
