Pinto Lake County Park Skatepark

The project consists of the construction of a new skatepark and associated site improvements at Pinto Lake County Park, including modification of an existing biofiltration planter along Green Valley Road to comply with County Design Criteria (CDC) stormwater requirements. The skatepark will provide a public recreational facility serving County residents and park visitors. Associated improvements include removal of an existing asphalt path, installation of a cobble-lined swale and area drains to convey runoff to the modified biofiltration planter, and implementation of Low Impact Development (LID) measures and Best Management Practices (BMPs) to minimize hydrologic and pollutant impacts. The total new and replaced impervious area associated with the project is 9,733 square feet, classifying the project as a Large Project under the County Design Criteria and triggering full LID and BMP compliance requirements. The biofiltration planter will be redesigned to provide stormwater treatment and detention consistent with CDC requirements, including detention of runoff from the 10-year, 15-minute storm event at the 5-year pre-development release rate, as required for projects within the Salsipuedes Creek Watershed. To accommodate the proposed skatepark, three (3) mature London Plane trees will be removed as part of site preparation. All remaining on-site trees will be protected in place pursuant to the recommendations of a certified arborist retained for the project. In response to the tree removals, six (6) new trees will be planted on-site, representing a net gain in tree canopy. In addition, all biofiltration planters and associated landscape areas will be planted with 100% native understory species, enhancing habitat value, supporting local pollinators, and reducing long-term landscape maintenance needs. The skatepark footprint will be constructed on areas currently occupied by unused turf grass that required irrigation to maintain. The replacement of non-functional turf with the skatepark hardscape and native plantings will result in overall water savings, consistent with the County's water conservation goals and the State's urban water use reduction objectives. The remainder of the site will be retained in its natural state, further minimizing the project's environmental footprint.
