609 RE-35 Single-Family Residence District.

A.    Purpose. A basic purpose of these regulations is to foster the creation of living areas which can assist the establishment of stable, functional neighborhoods. An established pattern of living in this metropolitan area reflects a tradition of single-family occupied dwellings which also emphasize outdoor living. Many of these dwellings are thereby located on relatively large urban or suburban lots.

These regulations provide standards for dwellings built at low and moderate densities. While the predominant housing type is expected to be single-family dwelling, provisions are made for alternative housing types within the same density limits.

B.    District Regulations. The following tables establish standards to be used for each district. Following are definitions of terms used in these standards:

1.    Minimum Lot Dimension: The minimum width and depth of lot lines and where specified, the minimum area of each lot.

2.    Dwelling Unit Density: The total number of dwelling units on a site divided by the gross area of the site. Under the planned residential development option, additional density may be granted for areas beyond minimum required in each district in accordance with the following:

a.    A one percent density bonus for each four percent of basic common area; or *6

b.    A one percent density bonus for each two percent of improved common area. *6

c.    Review and determination of the adequacy of common areas, basic and improved, will be part of the development review by the Site Planning Division of the Planning and Development Department. Open space shall not include: *6

(1)    Public right-of-way.

(2)    Vehicular drives or parking areas.

(3)    Private patio areas, narrow strips between or in front of units; or, in general, areas reserved for the exclusive use of individual tenants.

(4)    Required setback areas at the exterior boundaries of the site.

(5)    Golf courses.

3.    Perimeter standards: Setbacks for structures which are required at the perimeter of a development. These standards shall apply only to lots which are created by a subdivision or a project approved under the provisions of Section 507. These standards shall not apply in the following circumstances: when contiguous developments are to be developed using the same development option with the same perimeter standards and are on the same preliminary plat or are platted concurrently; when the perimeter of a development is contiguous to a permanent open space, such as a natural wash, hillside preserve, or existing golf course, the depth of which is at least forty feet; or when the development was properly platted prior to September 13, 1981. *2

4.    Building setback: The required separation of buildings from lot lines.

5.    Maximum height: The maximum allowed height as measured from natural grade which measurement shall be as in chapter 2

6.    Lot coverage: The maximum area of a lot occupied by structures and open projections as defined in chapter 2

7.    Common areas: Required areas in a planned residential development to be used and enjoyed by residents of a development and either improved in accordance with the standards in chapter 2 or maintained in a natural state as approved by the Planning and Development Department. *2

8.    Allowed uses: Refer to the following tables for uses allowed in each district and to chapter 2 for definitions of permitted uses.

9.    Required review: Where a site plan is required, development shall be according to Section 507 of this ordinance. Development on land for which neither a subdivision nor a site plan has been approved shall be according to standards in option (a), subdivision.

10.    Required parking: The minimum number of off-street parking spaces to be provided and which shall be according to Section 702.A.

11.    Street standards: The class of street required to provide access to any parcel or subdivided lot within a development.
