5. Low Impact Development:
“A stormwater management and land development strategy applied at the parcel and subdivision scale that emphasizes conservation and use of on-site natural features integrated with engineered, small scale hydrologic controls to more closely mimic pre-development hydrologic functions.” (PSAT, 2005)
The DoE along with local government agencies and the Washington State University Extension office have developed a Low Impact Development (LID) manual to assist designers with Best Management Practices (BMP) concerning stormwater runoff (PSAT, 2005). The purpose of the manual is to help designers and agencies understand the goals of low impact development, a common understanding of storm water practices, and specifications concerning stormwater runoff.
The city of Marysville, WA has local jurisdiction over the storm water permit process and determination of what measures must be taken to control and treat the storm water runoff. They have adopted the LID manual as a reference.
