In 2013, the Creeks Division completed construction of the Oak Park Storm Water Infiltration Project. The existing asphalt parking lots, stage area, and picnic areas were removed and replaced with permeable pavers, designed to help improve local creek and ocean water quality.
The project is designed to capture and treat polluted storm water and incidental runoff, and allow it to soak slowly into the ground. This prevents pollutants like oil and auto fluids from leaking cars, metals, and nutrients from flowing into storm drains, which lead directly to our creeks and ocean untreated.
Water flows between the pavers and into carefully selected and compacted rock below, and then into the ground, where it will be naturally treated by microbes in the soil. This infiltration prevents runoff and helps recharge groundwater.
The first phase of the project included the Tennis Court parking lot (on Tallant Road), and was completed in October 2013. The second phase of the project included the main parking lot (on W. Junipero Street), stage area, and picnic area, and was completed in December 2013.
Funding for this project has been provided in part through a grant agreement with the State Water Resources Control Board.
