The Mitchell Park Bioretention Project will manage stormwater runoff from the surrounding residential neighborhood. Stormwater infrastructure in this area is generally of inadequate capacity resulting in localized flooding. Additionally, runoff flows and pollutants impact the downstream creek habitat and beneficial uses.
This project will capture and infiltrate approximately 25% of the 85th percentile, 24-hour storm event from the contributing four acres. Mitchell Park provides an opportunity to cost-effectively support the City of San Luis Obispo’s stormwater management objectives while maintaining current park uses. The high visibility of the park location is suitable for educational signage offering information on Green Infrastructure and Low Impact Development.
