Zoning
T-5.1
Downtown Traditional Center Districts
The Downtown Traditional Center zone is characterized by medium to larger sized buildings in a compact urban environment that generates an active street life. There is interplay between the Public Realm of the busy street and sidewalk, and the Private Realm of the residential stoops, commercial storefronts and gallery building fronts. The increased building widths form a more solid and compact street wall pattern, generating an energized traditional downtown feel.
