Post-Construction Stormwater Management

Minimum Control Measure (MCM) 5


The purpose of the fifth MCM is to effectively manage post-construction stormwater discharges to the Town’s MS4. This measure involves requiring stormwater control measures (SCMs) to be installed with new development projects.


Small body of water surrounded by sloping land, trees, and rocks along one embankment.

Stormwater Control Measures (SCMs)


SCMs refer to engineered practices designed to:
  • Promote groundwater recharge
  • Provide flood control
  • Reduce downstream erosion
  • Remove pollutants from stormwater runoff

Runoff Control Program


The post-construction runoff control program applies to new developments that disturb an acre or more of land, including projects less than 1 acre that are part of a larger common plan of development. The program is designed to control stormwater runoff from new development sites and to ensure long term operation and maintenance of SCMs.
