Zoning Handbook

The purposes of the RA-3 zone are to:

  • Permit flexibility of design by permitting all types of urban residential development if they conform to the height, density, and area requirements established for these districts; and
  • Permit the construction of those institutional and semi-public buildings that would be compatible with adjoining residential uses and that are excluded from the more restrictive residential zones.

The RA-3 zone provides for areas developed with predominantly medium-density residential.
