Comprehensive P l a n z o z z <br /> (DRAFT 03/18/22) <br /> • Management of Post Construction Site Runoff <br /> • Good Housekeeping in Municipal Operations <br /> Mashpee has established a Stormwater Management Task Force to develop and implement a Townwide <br /> Stormwater Management Plan (SWMP) to fully comply with the new National Pollution Discharge <br /> Elimination System (NPDES) permit and to continue to mitigate the impacts of stormwater runoff with <br /> the town (Town of Mashpee). <br /> Uncontrolled I1::::rosioin and Sedhuneint <br /> Land development, when not properly managed, can have a detrimental effect on surrounding <br /> infrastructure and the function of the natural environment. When proper site preparation and <br /> maintenance do not occur during development, excessive quantities of soil can erode from the site.This <br /> situation can result in costly repairs and damage to the environment.The sediment can clog stormwater <br /> infrastructure, muddy streams, and leave deposits of silt in ponds and reservoirs and is considered a <br /> major water pollutant. Improperly managed construction projects can negatively impact aquatic habitat <br /> through erosion and sedimentation from construction sites (Town of Mashpee). The Erosion and <br /> Sedimentation Control section in the Town Bylaw ensures the prevention or reduction of soil erosion and <br /> sedimentation before,during, and after development or redevelopment of a site by requiring an Erosion <br /> and Sedimentation Control Plan to be submitted to the Town for approval before any construction takes <br /> place, except for some activities which are exempt from the requirement (Town of Mashpee, 2019). To <br /> help prevent soil erosion, Chapter 82 — Earth Removal under §82-3 Sand and Gravel Pits of the Town <br /> General Bylaw requires sand and gravel pit owners to replant trees or shrubs in areas larger than 5,000 <br /> square feet. <br /> *trogein Controll <br /> Nutrient-related water quality decline is a serious threat to coastal waters and freshwater ponds in <br /> southeastern Massachusetts.The Massachusetts Estuaries Project(MEP)technical report indicated that <br /> the Waquoit Bay and the Popponesset Bay system are in impaired water quality as they exceed their <br /> critical threshold for nitrogen (Cape Cod Commission, 2017). The Comprehensive Watershed Nitrogen <br /> Management Plan is the culmination of multiple documents examining the needs and coordinating <br /> efforts of the Massachusetts Estuaries Project (MEP) (Town of Mashpee, 2019). The Mashpee Sewer <br /> Commission is exploring the expansion of Phase 2 of the Town's Comprehensive Watershed Nitrogen <br /> Management Plan to include lakes and ponds(Jung, 2021). <br /> Nitrogen is detrimental to the water quality of Mashpee's ponds, streams,and bay area. Excess nitrogen <br /> can also cause algae blooms,which lower oxygen levels and lead to long-term damage to the ecosystem <br /> (Town of Mashpee, 2021). The Nitrogen Control section in the Town Bylaw aims to conserve valuable <br /> waterways and other resources that increase property values, protect the unique environment vital to <br /> the local economy, and reduce the financial burden on taxpayers and property owners by regulating the <br /> outdoor application of nitrogen and phosphorous on turf (Town of Mashpee, 2019). The regulation of <br /> fertilizer applications will reduce the overall amount of excess nitrogen and phosphorous entering <br /> resource areas as defined in the Mashpee Wetlands Protection Bylaw (Town of Mashpee, 2019). The <br /> Town also seeds shellfish as a remedial action for estuaries approaching their nitrogen targets(Town of <br /> Mashpee, 2018). <br /> II°°lazardous and I1,,,,aindfillll Areas <br /> westonandsampson.com Weston <br />
