The MEP model estimates that build-out would include an additional 2,468 <br /> residential properties for a total residential fertilizer input to the watershed of approximately <br /> 13,325 lbs/year or 6,045 kg/year, representing almost a 40% increase in residential fertilizer <br /> loads, or almost 3%of the current controllable load to Pleasant Bay. This indicates that new <br /> development may represent a significant increase of nitrogen input from fertilizer sources. <br /> 2.3 PLEASANT BAY WATERSHED FERTILIZER PRACTICES <br /> HW contacted municipal staff and golf course superintendents to confirm nitrogen loading on <br /> municipal properties and golf courses within the watershed. <br /> Municipalities (fields and lawns) <br /> HW contacted municipal staff in charge of lawn care on town-owned properties in each of the <br /> four towns, and received information from three towns. These included staff from the <br /> Departments of Public Works (DPW),Parks and Recreation, and Parks and Beaches. Overall, <br /> most Towns currently only fertilize fields and high-visibility areas (e.g.,Town Hall),which are <br /> of limited extent within the watershed. <br /> Brewster(Source: Robert Bersin, DP)Yj <br /> Most municipal land is not fertilized in Brewster. Within the Pleasant Bay watershed,the Town <br /> of Brewster only applies fertilizer to fields near Freeman's Way, but applications are limited <br /> because the area is within the zone of contribution to a public water supply well. <br /> Chatham (Source:Dan Tobin, Parks and Recreation <br /> Most municipal land is not fertilized in Chatham. Athletic fields, high school grounds, and areas <br /> of a high-use park are the most fertilized areas,with three applications per year(late spring in <br /> Pleasant Bay Fertilizer Management Plan 4 Horsley Witten Group,Inc. <br /> Final Report December 2010 <br />
