Low Impact Development

The Low Impact Development (LID) Manual is a site design approach that utilizes Green Infrastructure to meet a development site’s post development stormwater runoff water quality requirements. This approach satisfies the new MS4 Permit requirement to infiltrate, evapotranspire, or harvest and use the first inch of rain.

Water Quality Buffers

New development and significant redevelopment sites are required to preserve water quality buffers along Metro’s community waters, which include streams, rivers, springs, lakes, ponds, and wetlands. Please see Metro’s Stormwater Management Manual, Volume 1, Section 6.9 for additional information.

Stormwater Control Measures

Permanent stormwater treatment practices or control measures taken to mitigate changes to both quantity and quality of urban runoff caused through changes to land use from development.
