Village of Port Jefferson Mill Creek Watershed Management Plan 4.0 STORMWATER POLLUTANT CONTROL RECOMMENDATIONS 4.1 WATERSHED-WIDE MITIGATION RECOMMENDATIONS Strategies to minimize point and non-point source pollution and improve the Creek corridor habitat require an integrated, approach involving natural resource protection, educational efforts, watershed-wide management measures, land use modifications, nonstructural source control best management practices, site-specific structural control measures and target project recommendations. Natural resource recommendations focus on actions that will result in habitat improvements and protection along the creek corridor. Education and outreach recommendations focus on increasing the information available to community members including residents, property owners, businesses and municipal employee and agencies on ways they can modify behaviors and activities to reduce pollution deposits. Point and non-point source management and control recommendations include actions to mitigate the levels of pollutants generated and to remove pollutants in runoff prior to outfalling into the Creek. Water quality and pollution reduction monitoring includes measures to monitor and assess changes in water quality and pollutant levels over time. 4.1.1 NATURAL RESOURCE IDENTIFICATION, PROTECTION AND RESTORATION RECOMMENDATIONS These following recommendations are proposed to promote restoration and protection of the natural resources and improve the health of Mill Creek. The long-term ability to implement improvements to Mill Creek is contingent upon the ability to sustain support and encourage collaboration with local groups and organizations. This section identifies measures for creek corridor restoration, property acquisition, land use modifications, creek maintenance and habitat and water quality monitoring.
