The intent of this project was to design a surface parking lot around an existing sanitary lift station on a city-owned lot to provide overflow parking for the adjacent low-rise residential townhomes on the opposite side of Hawthorne Avenue. The site plan for this project had to preserve the Public Works Department’s ability to access and maintain the lift station.
Design services for this project included retaining, treating, and disposing of stormwater runoff within the property limits. The project also included meeting the Public Works department’s new criteria for stormwater drainage which includes a crown-of-road elevation of 3.7’ NAVD, mean high water elevation of 0.51’ NAVD for stormwater discharge, and raised seawall elevations of 5.7’ NAVD. Stormwater drainage was treated and disposed of via TWO (2) new deep underground injection wells at the Northwest and Northeast corners of the property.
In the spirit of the City’s new resilient design strategies and criteria, any opportunities to increase landscaped areas were explored including utilizing the curb in lieu of wheel stops, thus providing an 18’ parking stall that included 1.5’ of landscaping. All parking stalls were proposed pervious concrete to allow from natural percolation and drainage to reduce the amount of impervious surfaces on-site. All lighting on-site used LED luminaires. The electrical conduit was also installed to allow for a future charging station connection capable of charging TWO (2) electric vehicles simultaneously.
