(a) Purpose. It is the intent of the Residential Expansion District (RES EXP) to permit a full range of high density single and multi-family housing for developments that meet the definition of a Level III development. It is intended that proposals in this district include a broad range of housing types and be located near employment centers, shopping facilities, roads and other urban infrastructure capable of handling the demand generated by higher density residential development. The Residential Expansion District is a conditional district that is applied for through a rezoning application.
(b) Allowable land uses. All permitted uses in the Residential Expansion District are identified in the Table of Permitted Uses, Sec. 7-8-1d).
(c) Reserved.
(d) Development standards. All proposals in the Residential Expansion District shall meet the following development standards:
(1) Density standands. The maximum residential density per acre within the Residential Expansion District shall be 20 dwelling units; or 50 dwelling units if 20 percent of the Jwelling units meet affordability standards set by the City for households earning 80 percent or less of area median income. Affordable units must be affordable to and leased to income eligible households for at least 20 years. For sale units must be available to income qualified households for the initial sale.
(2) Structure size standards. None required.
(3) Lot size standards.
a. Multifamily development: one acre
b. Single family development: 3,500 square feet.
(4) Lot width standards. Minimum lot width: 40 feet.
(5) Setback standards. The following minimum setbacks shall be required for uses in the Residential Expansion District.
Multifamily | Single family | |
Front: | 15 ft. | 15 ft. |
Side: | 15 ft. | 6 ft. |
Rear: | 15 ft. | 15 ft. |
The landscape and buffering standards (section 7-11-3) will apply such that other residentially zoned properties shall be buffered with minimum 'A' buffer.
(6) Impervious surface standards.
a. Multifamily: Maximum 80 percent
b. Single family: Maximum 50 percent
(7) Height standards. The maximum height of structures in the Residential Expansion District shall be 60 feet for multifamily developments. For single family structures, building height is limited to 40 feet.
(8) Landscape and buffering standards. Landscape and buffering shall be provided as required by section 7-11-3 of this chapter except that a property line 'A' buffer is required for multifamily developments when adjacent to residentially zoned property.
(9) Parking and loading standards. Parking and loading facilities shall be provided as required by section 7-11-2 of this chapter. In addition, for multifamily developments, parking is not permitted between the building(s) and the primary access corridor(s). Parking may occur outside of required setbacks along secondary streets or along driveways within the develop- ment.
(10) Sidewalk standards. Sidewalks shall be provided as required by and pursuant to the requirements for sidewalks as set forth in section 7-11-8 of this chapter except that in addition to sidewalks provided along the primary access corridor, sidewalks will be required to connect to the principle residential buildings within the development and shall meet a ten-foot wide minimum standard for multifamily development and a five-foot wide minimum standard for single family and duplex development.
(11) Access and mobility standards. Multi- modal access to the development shall be analyzed at the planning stage. Vehicular access to the development should be limited to arterials or collector streets with a single driveway connection for multifamily developments. Developments that propose a single family layout with individual lots or a development that most closely resembles a single family pattern, vehicular access may occur from local streets with the approval by the city traffic engineer. Bike lanes into the development and on internal streets (if applicable) should be a part of the development plan. Access and cross access should be evaluated to connect to adjoining properties to improve roadway capacity, ensure driver safety and mobility options for bicyclists and pedestrians. Stub out connections may be constructed if cross access is not available. Transit shelters should be considered for developments along transit routes coordinated with the transportation department. Greenway connections through the development or to nearby existing or planned greenways should be provided for.
(12) Open space standards. Open space shall be provided as required by section 7-11-4 of this chapter.
(13) Design and operation standards. It is the intent of the residential expansion district to provide a wide range of housing types within the development. When a proposed project is located adjacent to residentially zoned areas, it should be compatible with the immediate neighborhood context in the following ways: building scale, setback and relative height of structures should transition to the existing neighborhood fabric. The proposed development shall comply with adopted neighborhood plans or design guidelines if applicable.
(14) Emergency wireless conununications. Communication requirements shall be provided as required by section 7-11-9 of this chapter.
