Construction

Uncontrolled stormwater runoff from construction sites can significantly impact our streams. 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.

In partnership with the Dauphin County Conservation District, and in association with our MS4 permit, Londonderry Township has a program to reduce pollutants in stormwater runoff to the MS4 for construction sites disturbing one or more acres.

We have developed measures to comply with our permit:

• An ordinance,

• 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.

Most types of construction require local permits, and construction sites disturbing one or more acres of land may require additional permits.
