Parking De-mystified
What is one of the most overlooked obstacles to transit-oriented development? Parking! Join us as we de-mystify the science of parking and turn traditional theories on their heads. Explore the fundamental topics of shared parking, parking demand estimation, parking code impacts, in-lieu fees, parking management, parking technologies and safe parking design. Hear best practices from the parking management toolbox developed for the San Diego Association of Governments (SANDAG). Learn how other communities benefit from implementing a comprehensive parking management system -- from new revenue streams to the creation of business improvement districts.
