The residential districts are established to preserve and enhance the quality of living in residential neighborhoods, to regulate structures and uses which may affect the character or desirability of residential areas, to encourage a variety of dwelling types and locations and a range of population densities consistent with the City's comprehensive plan, and to ensure adequate light, air, privacy, and open space. The residential districts and their purposes are as follows:

(1)

R-1 Low-Density Residential District provides an environment of predominantly single-family dwellings on moderately sized lots. Infill development is encouraged on lots that are consistent in size and dimensions with the predominant lot size and type on adjacent parcels. Two-family dwellings are permitted in limited numbers, consistent with the goals of promoting affordable housing and encouraging a variety of housing sizes and types in each neighborhood.

(2)

R-2 Medium-Density Residential District is established to provide an environment of moderate-density single- and two-family dwellings, townhouses, and small multifamily buildings that are designed to be compatible with their neighbors.

(3)

R-3 Varied Density Residential District is established to provide for an environment of moderate- to high-density attached and multifamily housing designed to present an attractive appearance to neighboring streets and adjacent uses, to include sufficient private and semi-private outdoor space, and to be well integrated into their surroundings.

(4)

RR Rural Residential District is established to provide for limited large-lot development in areas of the City not yet served by public utilities, as defined by the Urban Reserve District (a municipal service district). In these areas, the intent is to facilitate future urban development in a cost-effective manner that allows for logical street connections and open space protection. In areas served by public utilities, the RR district provides a low-density residential environment and allows for the option of conservation subdivision design.

Where at least 50 percent of the front footage of any block is built up with principal structures, the front yard setback for new structures shall be equal to the average of the existing structures, except that any structure which is set back 20 percent more or less than the average may be discounted from the formula.

^d

If townhouses are developed on parcels where only the land immediately beneath each dwelling unit constitutes an individually-described lot and all other land constitutes common properties, the density requirement rather than the minimum lot size shall apply to the entire parcel.

^e

Side yards: Setbacks shall apply to the ends of attached or semi-detached dwellings.

^f

^g

Heights of structures may be increased with a conditional use permit as permitted in Section 44-83.

^h

Covered porches are permitted in the front setback compliant with the conditional use permit requirements found in Section 44-83. A porch proposed for a designated historic property or a contributing building within a historic district may be constructed within a front and/or side yard setback provided the porch is historically appropriate or a restoration of a significant architectural feature of the original structure.
