Key changes include amending the definition of 'Historic Resource', clarifying rear yard requirements in NC-S Districts, reinstating front setback requirements, clarifying the inclusion of 'Mandatory Discretionary Review' for certain projects, modifying mailed notice requirements, reinstating controls for Intermediate Length Occupancy, and clarifying ground floor commercial uses in the Polk Street NCD. The Planning Commission adopted a recommendation for approval with modifications.
