KOA prepared a parking study in the City of Tustin for the Downtown Tustin Commercial Core. The City is developing the Downtown Commercial Core Specific Plan (DCCSP) composed of six Development Areas (DA’s) with a variety of development that includes small-scale restaurants, retail shops, office space, and integrated residential mixed-use buildings. The ultimate goals of the DCCSP is to revive the downtown Tustin area with opportunities to live and work in a walkable, bikeable, and transit-accessible environment. To achieve this goal, understanding existing parking demand and providing adequate and incentive/innovative parking requirements for future developments is important. This parking study evaluated the existing parking conditions, including identification and documentation of parking supply, demand, utilization, regulations, and management practices. The study also identified strategies that may better utilize existing parking facilities, provide future parking demand forecasts, and made recommendations for the most timely and cost effective parking improvements appropriate for the Tustin Downtown Commercial Core.
