2009 Stormwater Mitigation Handbook for LA Builders and Developers

The City of Los Angeles recently produced a new Standard Urban Stormwater Mitigation Plan (SUSMP) handbook entitled How to Build Protection for Mother Nature Into Your Project for local designers and developers. To view or download the handbook, click here.

Depending on the type of project, either a Standard Urban Stormwater Mitigation Plan (SUSMP) or a Site Specific Mitigation Plan is required to reduce the quantity and improve the quality of rainfall runoff that leaves the site. Developers are encouraged to coordinate with the City’s SUSMP Public Counter staff during the design phase of their projects to ensure compliance with these regulations. The handbook also provides information on stormwater mitigation features such as vegetated filter strips, porous pavement, flow-through planters, parking lot tree wells, infiltration swales, and rooftop water capture systems.

SUSMP or Site-Specific Mitigation Plans are required as part of a project plan submittal package. Project applicants should contact the City of Los Angeles’ SUSMP Public Counter before submitting a building permit application to the City’s Department of Building and Safety. The City’s SUSMP Public Counter is located at 201 North Figueroa Street, 3rd Floor, Station 18, Los Angeles. CA. SUSMP staff can be reached by calling (213) 482-7066.
