San Lorenzo Community Park

San Lorenzo, CA


PACE designed a nearly two-acre lake as part of San Lorenzo Park’s renovation. This lake not only adds serene aesthetic value to the park, it also manages the park’s stormwater and recycles it by using the water for irrigating the surrounding landscape. To maintain water quality, the lake uses an alum addition to remove nutrients and settle particulates out of the water. Additional water quality management systems include sand filtration, circulation, wetland plants, and an aeration system. PACE designed a naturalized shoreline for the lake using a concrete shell and embedded cobble rocks along its edge to create a natural earthen look. Aquatic plants line the shoreline of along approximately 80% of the lake’s perimeter.


Key Features:

  • Water quality management system features an alum discharge settling box
  • Amended soil liner prevents water from seeping into the ground
  • Aquatic plant shoreline for 80% of the perimeter
  • Dry weather runoff and stormwater are collected and treated within the lake and is recycled as a landscape irrigation source
