What is SUSMP?  In 2000 the State Regional Water Quality Control Board created SUSMP, which is the Standard Urban Storm water Mitigation Plan. This plan is designated as part of the municipal storm water program to handle storm water pollution for new construction and remodeling projects. SUSMP is very important when it comes to construction because it regulates how development project need to be designed in order to protect water quality. Any time rainwater falls on a roof or parking lot the water runoff may pick up various pollutants such as oil or trash, which is then carried off into bodies of water, such as the ocean. The impact of SUSMP is crucial because it offers technical guidelines for design projects that will reduce the negative affects on water quality from a development.
