The Stockley Center is home to the headwaters of Cow Bridge Branch, one of the Delaware Inland Bays’ least disturbed tributaries. This project, along with a 2014 stream channel restoration project, further protects one of the most pristine areas of the Inland Bays watershed by addressing erosion and runoff problems.

What was once a stagnant stormwater pond has been turned into a bioretention facility which stabilizes the failing slope, reconstructs the riprap inflow channel, and rebuilds the forebay. The project is estimated to improve water quality through the incorporation of biochar, a soil amendment that will increase the retention of nitrogen and water. The retrofit will reduce nitrogen loads by 17.13 lb/year of nitrogen and phosphorus by 2.31 lb/year.
