Resources for Developers and Site Operators


Resources for Developers and Site Operators
Stormwater discharges from construction activities that disturb one or more acres or smaller sites disturbing less than one acre that are part of a larger common development are regulated under the NPDES stormwater permitting program. Falmouth’s Stormwater Regulations have requirements for developers and site operators designed to protect water quality. Prior to the start of construction, operators must obtain coverage under a NPDES permit, administered by EPA under the Construction General Permit (CGP). The CGP requires operators of construction sites to meet effluent limits and requires operators to develop a Stormwater Pollution Prevention Plan (SWPPP) detailing the erosion and sediment controls and pollution prevention measures that will be implemented to meet the requirements of the CGP.

The following practices will help reduce the volume of stormwater created and help prevent pollutants from coming in contact with stormwater. Click the links below to learn more!

  • Reduce the amount of runoff from development – maintain existing vegetation where possible. Learn more!
  • Use erosion controls – install perimeter controls such as hay bales and silt fences, and reduce the total amount of impervious cover on your site. Learn more!
  • Encourage infiltration – install infiltration-based features such as rain gardens and bioswales. Learn more!
  • Only rain down the drain – protect all storm drain inlets and streams located on your construction site or property.
  • Limit access – access to and from the site should be limited and stabilized construction entrances and exits should be used by all construction equipment.
  • Use Low Impact Development (LID) practices – LID is an approach to land development that works with nature to manage stormwater at the source and includes principles such as preserving and recreating natural landscape features and minimizing effective imperviousness. Incorporate Lid practices to site designs. Learn more and more!
  • Protect stockpiles – stockpiles should be stored under a roof, impermeable tarp, or plastic sheeting. Do not store or stockpile materials near a storm drain, wetland, or stream. Stockpiles should not be placed over locations for existing or future stormwater infiltration or septic system leaching areas.
  • Maintain elsewhere – perform major maintenance and repair of vehicles off site.
  • Use washout areas – wash out concrete mixers only in designated washout areas away from resources, and set up small mixers on tarps.
  • Designate waste disposal areas – remove trash, debris, and wastes on a regular basis and ensure that dumpsters are covered.
  • Clean up small spills – immediately clean up small spills using dry clean up methods.
  • Permits – make sure you have a permit from EPA if you’re disturbing more than an acre. Learn more!
