The City regulates stormwater management of all construction sites based on guidance given by Provision C.6 of the Municipal Regional Stormwater Permit (i.e. MRP, No. R2-2015-0049, link here), City inspectors confirm implementation of appropriate and effective erosion, run-off and run-on, and sediment controls as well as other pollution and site management practices (often referred to as Best Management Practices, i.e. BMPs) by construction site operators/developers. Follow-up and enforcement activities at construction sites help minimize the discharge of pollutants into the storm drains. Such discharge can lead to sediment, chemical and microbial pollution of receiving waters like Marina Lagoon or San Francisco Bay. Learn more about related practice at the San Mateo Countywide Water Pollution Prevention Program's webpage on Construction Sites, with link here.
