LID design and implementation

Implementation of City of Sacramento LID Standards at Sacramento State

The City of Sacramento contracted with OWP in 2014 to manage and implement a grant from the CA State Water Resources Control Board. The project consisted of designing, installing, and monitoring stormwater low impact development (LID) best management practices (BMPs) on the campus of Sacramento State, as well as conducting an extensive education and outreach program that includes workshops, webinars, walking tours, and a regional LID conference. The City was the prime awardee because of a grant condition, but opted to contract with OWP to serve as the technical liaison between the City and university. OWP staff collaborated with multiple university entities to facilitate planning, design, and construction of multiple LID BMPs on campus, including bioretention planters, rain gardens, down spout disconnects, an infiltrating bioswale and porous pavement. OWP staff also performed BMP sizing using the Sacramento Hydrologic Model, conducted field monitoring, evaluated and documented performance results, and executed all outreach activities.

CA Phase II LID Sizing Tool

In 2013, OWP was awarded a Proposition 84 grant from the State Water Board’s Stormwater Grant Program: The CA Phase II Low Impact Development (LID) Sizing Tool. The LID Sizing Tool is a web-based program that assists stormwater practitioners in selecting and sizing LID best management practices that meet the sizing requirements in California’s National Pollutant Discharge Elimination System permit for stormwater discharges from small municipal separate storm sewer systems.

Sacramento LID Manual Update

OWP, working with the Sacramento Stormwater Quality Partnership, developed a point-based low impact development (LID) credit system to allow both developer and municipal plan reviewer to easily evaluate proposed best management practices (BMPs) to determine whether the LID requirements have been met.
