3 Board of Selectmen Minutes September 9, 2019 APPOINTMENTS & HEARINGS Department of Public Works Director Catherine Laurent: Stormwater Management Update: Catherine Laurent, Director of Public Works was in attendance with Gabrielle Belfit, Senior Environmental Scientist of Tighe & Bond, Environmental Engineers to review the Mashpee Stormwater Management Plan, a requirement of the 5-year permit due to expire in 2022. Tighe & Bond is assisting the Town on the matter of stormwater management. A report, considered a blueprint for the Town for compliance is anticipated to be finalized and distributed next week to meet the deadline of September 30, 2019 for submission to the state. Permit Year 1 requirements include public education and outreach and the adoption of a Bylaw relative to storm water discharge. The proposed Bylaw for Illicit Connections and Discharges to the Municipal Storm Drain System appears on the October warrant for adoption. Regulations are necessary for the protection of Mashpee's water bodies and groundwater, and to safeguard public health and safety,welfare and the environment. With the assistance of Tighe & Bond, the Department of Public Works has established a Stormwater Management Plan page with mapping on the Town's website; Nary«v.mashpeema.gov. Permit Yearn highlights include continued public education and outreach as well as the distribution of materials and opportunities for public participation. With the institution of the new Bylaw new development and redevelopment BMP's would be required for optimum nitrogen removal. An inventory of operations and maintenance procedures would be developed for all Town-owned parks, open space, buildings, vehicles and equipment. This includes cleaning catch basins and street cleaning on a bi-annual basis along with the implementation of a winter road maintenance program. Ms. Laurent, Director of the DPW indicated the Plan serves as a written document for stormwater management. There are no real changes or requirements to what the Town has been practicing. It was agreed that it is important to alleviate direct discharges from the rivers and ponds. It was recommended that more emphasis focus on roadways and redirecting drainage from the waterways. Ms. Laurent was in support of this action. The matter has been discussed with Town Manager Rodney C. Collins and would be considered as a separate line item for funding in FY21. All new road construction will include drainage work to limit sediment discharge and nutrient loading.
