Downtown Pleasanton Parking Lot

HMH was engaged by the City of Pleasanton to redesign and expand the City’s downtown parking lot on the former railroad property between Bernal Avenue and Abbie Street. The redesign looked at adding 81 new stalls to the municipal lot, plus other renovations including a retaining wall and site lighting while working with existing constraints that included hazardous materials in existing soil, underground utilities, existing grading, and disruption of downtown operations. The proposed design also maximizes parking, while providing a bicycle and pedestrian concrete walkway.

From a stormwater design perspective, the downtown parking lot stormwater design solution is seen as a signature stormwater project that the City can direct developers to as an example of how to design an efficient and aesthetically pleasing stormwater treatment facility. To achieve this, the project will combine the use of a tradition biotreatment cell and buried Silva cells and use a varied planting pallet to maintain a healthy looking facility year round.

The end result will be an ideal location to supplement downtown parking, create an enjoyable user atmosphere, promote multi-modal and low emission vehicles, offer bike racks and electric vehicle charging, and single element for earth retaining and stormwater treatment.
