With a historic drought showing no signs of letting up, the city of Los Angeles is drafting a new plan to use more local water sources by capturing storm water throughout the L.A. basin. At recent community meetings, officials from the Department of Water and Power (along with the city's Sanitation Department) have been showcasing potential ideas for the final plan, due out this summer.

This new plan would make storm water about 4 percent of the city's annual water budget. For the first time, LA is talking about making storm water a small but reliable part of the city’s water sources – 25,000 acre-feet, or somewhat over 8 billion gallons of storm water a year. For perspective, a typical one-inch rain event in Los Angeles County produces more than 10 billion gallons of storm water, most of which hits asphalt and concrete, flows into storm drains and goes to the sea.

It’s hardly a new idea. But storm water capture has taken on additional urgency because of the drought, because of the increasing price of importing water, and because of local water quality rules.

On top of that, Los Angeles Mayor Eric Garcetti issued an executive order last October, directing the LADWP to cut its purchase of imported water in half within a decade, in part by cutting water consumption at least 20 percent.

Storm water capture projects have captured the energy and attention of environmental groups who’ve demonstrated them in backyards, neighborhoods, and alleyways.

LA could invest in much-larger-scale versions of those ideas. Good places for those bigger projects tend to be in the San Fernando Valley, where the geology is hospitable to rain water capture and the city has clearest rights. 

Some examples featured in the LADWP’s presentation aren’t yet approved, but are in consideration:

• Water capture and storage at the Van Norman Complex; 
• The Canterbury Power Line Easement, running between the Tujunga Spreading Grounds and the Pacoima Wash, which would capture 1500 acre-feet of water a year; and 
• Converting Strathern Park (near the Hollywood Freeway) from a disused gravel pit/landfill to a wetlands park, in joint operation with L.A. County. 

Storing storm water in the ground means protecting some areas from industrial pollution, and means filtering and treating polluted groundwater as it’s pulled from aquifers. Last November’s $7.5 billion dollar water bond earmarked funds for storm water capture and for groundwater cleanup. DWP officials say they’re hoping to bring some of that money to Los Angeles.

Many airports undertake stormwater projects to accommodate facility expansion, address obsolescence, and respond to evolving regulatory requirements. Often, stormwater infrastructure is installed or upgraded on a project-by-project and piecemeal basis, resulting in mismatches of sizes, material types, ages, and conditions. When airports are considering expanding or improving their stormwater facilities, the immediate need for stormwater infrastructure modification may not be clear, and a benefit–cost ana...

Field Monitoring of Erosion and Sediment Control Practices and Development of Additional Iowa DOT Design Manual Guidance , released by the Institute for Transportation at Iowa State University

The first edition of this report, in 2009, provided a comprehensive industry reference for the management of airport deicing runoff. The second edition has been wholly updated to reflect the latest industry practices. The TRB Airport Cooperative Research Program's ACRP Research Report 14: Deicing Planning Guidelines and Practices for Stormwater Management Systems, second edition , explores a wide array of practices designed to provide for the practical, cost-effective control of runoff from aircraft and ...

By Kelly Scanlon, director, environment, health and safety policy and research, IPC The U.S. Environmental Protection Associations (EPA) is seeking public comment on a proposed 2020 National Pollutant Discharge Elimination System (NPDES) Multi-Sector General Permit (MSGP) for stormwater discharges from industrial activity. This proposed permit would replace the 2015 MSGP upon finalization. This proposed permit […]
