Uncontrolled stormwater runoff from construction sites can significantly impact rivers, lakes and estuaries. Sediment in waterbodies from construction sites can reduce the amount of sunlight reaching aquatic plants, clog fish gills, smother aquatic habitat and spawning areas, and impede navigation.
Phase II MS4s are required to develop a program to reduce pollutants in stormwater runoff to the MS4 for construction sites disturbing 2500 square feet or more. This primarily includes developing:
Requirements to implement erosion and sediment control best management practices (BMPs),
Requirements to control other waste at the construction site,
Procedures for reviewing construction site plans,
Procedures to receive and consider information submitted by the public, and
Procedures for inspections and enforcement of stormwater requirements at construction sites.
Specific ordinances have been developed by the City of Fredericksburg to guide the public and local businesses through proper construction procedures to ensure minimal erosion and sedimentation of local waterways.
