HomeMy WebLinkAboutSTATEMENT OF WATER QUALITY IMPACT STATEMENT OF WATER QUALITY IMPACT CONSTRUCTION OF NEW PLAYING FIELDS DALE STREET,NORTH ANDOVER, MA Potential degradation of water quality associated with the development of new playing fields can be most closely associated with the following: • Construction activity resulting in erosion of soil into adjacent wetlands. • Increases in storm water runoff from impervious surfaces. • Chemical loading as a result of fertilizer and pesticide application. None of the above activities at the above referenced location will adversely impact the water quality in the adjacent wetlands and downstream waters, i.e. Lake Cochichewick due to the following: • Erosion control consisting of double staked hay bales backed by siltation fence will be installed between the project site and the wetland area along the 100 foot buffer zone line to prevent siltation during construction. • Environmental monitoring will be performed by a qualified engineer or wetland scientist to insure best management practices are exercised to prevent damage to wetland resource areas. • Due the fact that there will be no impervious area upon completion of the project and a detention pond will be constructed there will be a decrease in the rate of storm water runoff and a negligible decrease in stormwater recharge to the groundwater. • The users of the field will agree to the use of organic and low nitrogen fertilizers and curtailing the use of pesticides will reduce the potential chemical loading to adjacent wetlands. • The stormwater system utilizes deep sump catch basins, a sediment forbay, and a wet detention pond to insure that stormwater is properly treated prior to being discharged from the site. Further treatment will occur when the discharged stormwater flows overland through the existing forested buffer zone. Application of the above measures will result in no increase in concentrations of nitrogen,phosphorous and other dissolved inorganic chemicals.The quality of surface and ground water adjacent to Lake Cochichewick will not be adversely impacted by the proposed construction of the playing fields.
