of open spaces, personal and property security, wind and solar effects and the protection
of important public ways.
(7) Provision of safe and adequate access to and from sites giving ample consideration to the
location and number of access points from public streets, the safety and convenience of
merging and turning movements and traffic management mitigation.

interior drives, parking areas, pathways, and walkways adequate to handle anticipated
