That really doesn't require 50 foot high massive walls of blank concrete going up from the sidewalk. You can use bollards to address that threat with setbacks and still have human scale architecture. The bollards will stop any vehicle and they can look quite nice: https://www.degemmill.com/content/uploads/2017/07/Bollards-_-Site-Amendities_-Architectural-_-Decorative-Bollard.jpg https://www.degemmill.com/content/uploads/2017/07/Bollards-_...
