Stormwater quality improvements at Del Mar Fairgrounds set to begin next week

Significant infrastructure upgrades to improve water quality in San Dieguito Lagoon and Stevens Creek marine protected areas are scheduled to begin next week at the Del Mar Fairgrounds.

Improvements include the capture of stormwater from areas of the Fairgrounds where animals are housed and treatment of that stormwater to appropriate levels before being discharged into adjacent waterways. Key components of the estimated $10 million, two-year project with contractor Barnhart-Reese include: converting the Del Mar Racetrack infield water features into holding ponds for stormwater; constructing a wetlands area; and building a treatment plant that will remove pollutants from stormwater before it leaves the Fairgrounds.

The project is the effort of the 22nd District Agricultural Association (a state of California agency that owns and operates the Del Mar Fairgrounds), in collaboration with the San Diego Regional Water Quality Control Board, to assure that the stormwater discharged from those areas of the Fairgrounds where animals are housed is in compliance with applicable clean water requirements.

“We are pleased to embark on this project which furthers the Fairground’s commitment to environmental protection by preserving the water quality in the San Dieguito Lagoon and Stevens Creek,” said Tim Fennell, CEO of the Del Mar Fairgrounds.
