2017 APWA Sacramento Chapter Project of the Year Award
Parking Lot Features Low Water Landscaping and Infiltration Planters to Improve Stormwater
The Bridge District Parking Lot is part of a rehabilitation and development kick-start program in the City of West Sacramento for the Bridge District adjacent to Raley Field. The project provides additional parking for residents and recent developments such as The Barn, an outdoor event venue. Bennett Engineering provided the design for the parking lot, low impact development (LID) stormwater drainage, sidewalk, and ADA improvements.
The $1.1 million project included parking gates with electronic toll and entrance/exit tracking to monitor capacity, street signage announcing parking availability, parking lot planters with low water landscaping, and infiltration planters to improve stormwater quality. The project also incorporated improvements to sidewalks around the lot and two adjacent streets.
Design challenges for the roughly 270 space parking lot included managing offsite drainage and design considerations for future development. Water from offsite locations drains onto the parking lot, adding excess water during storms. Design for stormwater drainage was needed to address the problem while accommodating future plans to build a garage on the parking lot site. To minimize throw away, drainage was aligned to avoid areas that will need to be excavated for the future multi-story garage.
