40.230.020    Mixed Use District (MX)

A.    Purpose.

    The mixed use (MX) district requires mixed use developments to provide the community with a mix of mutually supporting retail, service, office and residential uses. It promotes cohesive site planning and design which integrates and interconnects two (2) or more land uses into a development that is mutually supportive. It provides incentives to develop a higher-density, active, urban environment than generally found in a suburban community, and which is further expected to:

1.    Achieve goals and objectives of the community framework plan and the comprehensive plan;

2.    Enhance livability, environmental quality and economic vitality;

3.    Accommodate and respect surrounding land uses by providing a gradual transition adjacent to lower density neighborhoods that may encircle a potential mixed use site;

4.    Maximize efficient use of public facilities and services;

5.    Provide a variety of housing types and densities;

6.    Reduce the number of automobile trips and encourage alternative modes of transportation; and

7.    Create a safe, attractive and convenient environment for living, working, recreating and traveling.

B.    Applicability.

1.    General. The provisions of this section shall be applied to parcels or groups of contiguous parcels designated mixed use on the zoning map.

2.    Interpretation. If the requirements of the mixed use district conflict with other regulations, the more stringent of the two (2) shall apply as determined by the responsible official.

C.    Definitions.

    For the purposes of this section, the following definitions shall apply:

1.    “Mixed use development” shall mean a group of structures planned as a single entity and containing within and/or among them a variety of complementary and/or mutually supporting uses (such as housing, offices, retail, public service or entertainment).

2.    “Developable area” means that portion of the site which is unencumbered by environmentally sensitive lands to be protected and their respective buffers, designated parks and open space, public right-of-way, and road easements.

3.    “Building footprint” means the area contained within the exterior building walls of the ground floor of a building plus the area of any portion of upper floors that extend outside of the footprint of the ground floor.

4.    “Cottage housing” means a collection of small single-family detached dwelling units arranged around a common open space.

5.    “Mixed use building” means any building that combines both permitted residential and nonresidential uses.

6.    “Net ground floor area” means nonresidential floor area and excludes parking areas.

7.    “Senior housing” means dwelling units specifically for occupancy by persons fifty-five (55) years of age or older.

D.    Uses. The uses set out in Table 40.230.020-1 are permitted or conditional in the mixed use (MX) district. Residential uses are permitted so long as the minimum required densities of this section are met. The appropriate review authority is mandatory.

•    “P” – Uses allowed subject to approval of applicable permits.

•    “R/A” – Uses permitted upon review and approval as set forth in Section 40.520.020.

E.    Mixed Use Standards.

1.    Residential.

a.    Whether within a single building or on a development site, a minimum of twenty percent (20%) of the development shall be nonresidential and a minimum of twenty percent (20%) of the development shall be residential. This percentage shall be calculated by determining the percent of developable area devoted to each type of use. For mixed use buildings, the percentage shall be calculated by one (1) of the following methods:

(1)    The percentage of total building’s floor area devoted to residential to nonresidential uses.

(2)    The percentage of net ground floor area (for nonresidential uses) to gross ground floor area (residential and/or parking areas).

b.    Exception. The responsible official may allow a reduction in the percentage of required nonresidential uses as required in Section 40.230.020(E)(1)(a), to a minimum of five percent (5%) provided all of the following criteria are met:

(1)    The development includes a vertical mix of uses in one (1) or more mixed use buildings. This shall include space for nonresidential uses on at least a portion of the ground floor and residential uses on one (1) or more upper floors;

(2)    The development site is not larger than two (2) acres; and

(3)    All ground floor residential units facing a public street shall maintain a minimum structural ceiling height of thirteen (13) feet to provide the opportunity for future conversion to nonresidential uses.

c.    A minimum density of twelve (12) dwelling units per acre is required. This shall be based on the developable area devoted to residential use. If the development site is greater than five (5) acres and less than fifty (50) acres, the residential use shall contain a minimum three (3) permitted housing types as set forth in the Mixed Use Design Standards in Appendix A of this title. If the development site is fifty (50) acres or more, the residential use shall contain a minimum four (4) permitted housing types as set forth in the Mixed Use Design Standards in Appendix A of this title.

d.    The maximum density shall be forty-three (43) dwelling units per acre. This shall be based on the developable area devoted to residential use. Exception: There shall be no maximum density for buildings featuring vertical mix of uses. To qualify, nonresidential uses (net ground floor area) shall occupy at least fifty percent (50%) of the building’s gross ground floor area. Residential uses shall occupy one (1) or more upper floors.

e.    Conversion of Existing Structures. An existing residential structure may not be converted to a commercial or office use unless consistent with this chapter.

2.    Nonresidential. All uses on the ground floor must maintain a minimum structural ceiling height of thirteen (13) feet.
