Pilot Projects

The City of San Diego Transportation & Storm Water Department conducts a number of pilot projects in an attempt to find the most efficient and cost-effective method in preventing pollution in local beaches, bays and the ocean. Projects include structural improvements to the City’s storm drain system, porous pavement projects, outreach programs designed to educate and change behaviors and attitudes in residents and businesses.

43rd and Logan Avenue Project

The City of San Diego (City) is installing a Low Impact Development (LID) pilot project as part of roadway improvements surrounding the intersection of 43st and Logan Avenue. The LID effort will use Best Management Practices (BMPs) to help capture and treat storm water before it can enter nearby Chollas Creek.

Chollas Creek Family Stream Team Initiative

The Groundwork San Diego Chollas Creek (GWSDCC) Chollas Creek Family Stream Team Initiative (CCFSTI) was a grant-funded effort to provide outreach and assistance by engaging the local community to participate in trash cleanup, landscape assistance, and trash collection activities to address illegally-dumped materials and pollutants in Chollas Creek. This program component is considered a non-structural best management practice (BMP) designed to reduce illegal dumping in the Chollas Creek watershed by providing periodic collection services where local residents can dispose of large, unwanted household items for free.

Kellogg Park Green Lot Infiltration Project

The California State Water Resources Control Board created Areas of Special Biological Significance (ASBS) to protect our oceans and prevent pollution within some of the most pristine and biologically diverse sections of California’s coast. La Jolla is home to two ASBS, which encompass a large portion of the La Jolla Shores marine environment. To address the issue of run-off into the ASBS, the City has developed a Priority Development project at Kellogg Park in La Jolla Shores. The Kellogg Park Green Lot project is designed as a treatment control utilizing Best Management Practices (BMPs) in the parking lot to treat storm water and urban runoff. The project includes elements that will capture surface runoff from the parking lot and public right-of-way. The elements will filter and infiltrate the water to minimize pollutants.

Rain Barrel and Downspout Disconnect Pilot Program

The Rain Barrel/Downspout Disconnect Pilot Program was developed to study the effectiveness of rain barrel systems at reducing polluted runoff and harvesting water during dry periods. The pilot program was designed as a cost effective way to reduce polluted runoff from entering San Diego beaches and bays, conserve water, and supplement existing water harvesting efforts.

Street Sweeping Pilot Studies

The City of San Diego continues to explore new ways to help prevent storm water pollution. As part of this ongoing effort, the Storm Water Division conducted a pilot study of street sweeping options for neighborhoods adjacent to important waterways. The studies involved assessment of what kind of street sweeping equipment and sweeping frequency helped reduce the amount of pollutants on our roadways.

Catch Basin Inlet Cleaning Pilot Study

The Catch Basin Inlet Cleaning plan focuses on characterizing accumulation rates and pollutants in four land use settings that broadly represent large areas of San Diego. These areas are specifically Downtown San Diego, a single-family residential area in San Ysidro, a residential area near Mesa College and Tecolote Creek, and a mixed commercial and office/retail area off of Scripps Poway Parkway and I-15. 4 clean-outs were performed during the winter season of 2011 to 2012.

Storm Water Runoff Impacts of Copper and Zinc Building Materials, Literature Review

This report reviewed zinc and copper as pollutants and how source abatement efforts may effectively serve as a BMP. The study concludes that the lack of studies for the application and management of zinc- and copper- based building materials limits the scientific foundation and understanding about the economic, social, political, and environmental implications of restricting the use of the materials.

Storm Drain Insert Pilot Study

This pilot study evaluated the performance and operations and maintenance requirements of storm drain insert best management practices (BMPs) at eight different locations throughout the City. Five different products were selected for evaluation during both wet and dry weather conditions. The level of effort required to maintain these BMPs was also evaluated. This study assists the City in consideration of future implementation of various BMPs and in storm water planning efforts.

Preliminary Evaluation of an Illegal Dumping Abatement Non Structural BMP

This report assesses the effectiveness of a non-structural best management practice (BMP) program designed to reduce illegal dumping in the Chollas Creek watershed. This report documents activities and analysis methods that were used to assess the effectiveness of parts of the Chollas Creek Family Street Team Initiative (CCFSTI) program that address illegal dumping and trash pollutant issues in portions of the Chollas Creek Watershed.
