Officials from the cities of Los Angeles and El Segundo marked the completion Thursday, November 5th of a median project for stormwater runoff along Imperial Highway.

Los Angeles City Councilman Bill Rosendahl, El Segundo Mayor Kelly McDowell and other local government representatives announced the completion of the Imperial Highway Sunken Median Stormwater Best Management Practice project during a ceremony at Imperial Highway, between Pershing Drive and Main Street.

The project included the installation of a biofiltration system comprised of vegetated swales and an infiltration trench that will collect runoff from a 7.5-acre area and remove bacteria, oil, trash and suspended solids from stormwater that would otherwise be discharged to Santa Monica Bay, according to the Department of Public Works.

Shrubs and trees were also planted in the project area, and an automated irrigation system that uses recycled water was installed.

“I am delighted that another Proposition O project in our district is complete,” said Rosen-dahl. “Yet again, we have developed a system that not only reduces the amount of pollution entering Santa Monica Bay but also beautifies our community.”

The Los Angeles Bureau of Sanitation initiated the project as one of the 32 stormwater improvements funded by the voter-approved Proposition O Clean Water Bond. Propostion O was approved by Los Angeles voters in November 2004 authorizing $500 million in bonds to be used by the city for water quality improvement projects.

“This project accomplishes our goal of utilizing green natural systems to manage stormwater as a resource while protecting the health and safety of marine life and beachgoers alike,” Bureau of Sanitation Director Enrique Zaldivar said.

“It also helps recharge groundwater and assists the city in complying with Environmental Protection Agency mandated water quality standards.”
