The purposes of the RA-4 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-4 zone provides for areas developed with predominantly medium- to high-density residential.
