(a) Purpose and intent. It is the purpose and intent of the Low Intensity Mixed-Use (MU-1) District to provide areas in which a variety of housing types exist among neighborhood-serving commercial and institutional uses. The MU-1 District is designed to accommodate and encourage compact, walkable development forms that are more land-efficient, cost-effective, and revenue positive for the City than low density, single-use developments. In addition to the purpose statements above, the intent of the MU-1 District is to:
(1) Promote a pedestrian-oriented urban form. In contrast to conventional zoning standards that place a primary emphasis on the regulation of land uses, mixed-use development standards and guidelines focus on promoting a walkable, urban form of development, consistent with the surrounding areas historic urban development patterns. The focus on form promotes buildings that conform to tested urban design principles.
(2) Require excellence in design of the public realm and of buildings that front public spaces. The most successful and memorable urban environments are those in which walking down the street is appealing. Streets, plazas, parks, and other public spaces should be comfortable and inviting, and buildings fronting those spaces should be active and visually interesting at the pedestrian level.
(3) Encourage creativity, architectural diversity, and exceptional design. Mixed-use is intended to promote high quality design, and the development review process for mixed-use projects is intended to promote flexibility. Standards, as well as the development review process, are intended to support creativity and exceptional design while discouraging uniformity.
(4) Promote sustainable development that minimizes negative impacts on natural resources. Creating walkable, higher density residential districts surrounding mixed-use districts supports sustainable development by providing an alternative to low density development in peripheral areas. In accordance with sustainable development principles, the mixed-use buildings and public spaces should be designed to minimize negative impacts on air and water quality and promote innovation in environmental design.
(5) Promote walkability. Walkable communities are desirable places to live, work, and play. Walkable communities give higher priority to pedestrian activity by creating streetscapes that are safe, comfortable, interesting, and that accommodate a wide range of transportation modes and users. To foster walkability, development patterns should promote a mix of land uses and density, have an emphasis on the placement and orientation of buildings, have properly placed parking, place a high value on the design of quality streetscapes, provide access to transit, and provide unimpeded pedestrian connections to multiple destinations and open space.
(6) Maximize connectivity and access. In order for people to feel comfortable walking, pedestrian access and connectivity among uses and amenities, including transit facilities, is essential. Connectivity and access can be accomplished by creating smaller blocks or by providing access through blocks via publicly accessible alleys, pathways, paseos, and pedestrian boulevards. Sidewalks should form a continuous network connected by frequent, safe street crossing.
(7) Promote affordable housing and mixed income communities. Design a mix of housing based on geographic growth projections and the needs of current and future residents to accommodate families, single occupants, the elderly and those with disabilities. Access to transportation and services should be a key factor in the future distribution and allocation of affordable housing.
(b) Review procedures for development.
(1) General requirements. Projects should conform to all mixed-use standards. Staff may also refer an administrative case or a case that does not require waivers to the UDC for failure to meet the Purpose and Intent of the ordinance.
(2) General rule allowing waiver or modification of standards.
a. Director or designee. The Director or designee is authorized to grant modifications to certain development standards with a maximum modification up to 10% increase or decrease for the following development standards:
1. Setbacks for additions to existing structures.
2. Bufferyard width.
3. Primary entrance separation.
4. Fenestration.
b. Urban Design Commission. Unless otherwise limited by this section, the Urban Design Commission (UDC), may waive or modify any individual development standards through the issuance of a Certificate of Appropriateness, if the UDC finds that the proposed development is consistent with the intent statements of the MU-1 District but does not conform to certain development standards. A Certificate of Appropriateness shall expire if a building permit is not received within two years of the approval of the Certificate of Appropriateness.
c. Board of Adjustment. Any waiver of basic property development related to building heights, setbacks and bulk require a variance to the Board of Adjustment after a recommendation from the Urban Design Commission.
d. Zoning Commission/City Council. Any zoning proposal requesting a Planned Development "PD" zoning district that uses the MU-1 District as the base zoning, inclusive of any waivers from MU-1 design standards, must receive a recommendation from the Urban Design Commission prior to a public hearing by the Zoning Commission or the City Council.
(3) Conceptual Land Use Plan. To facilitate compliance with the MU-1 District regulations, a conceptual land use plan must be submitted to the Director of designee for review and approval prior to submitting permit applications. The conceptual land use plan must include the following:
a. The anticipated location of proposed streets, sidewalks and walkways, building footprints, parking areas, landscaped areas and features, and open space. A change of 5% or greater in land uses to an approved conceptual land use plan will require a new project review and approval prior to permitting.
b. The conceptual land use plan shall illustrate the proposed location of land uses on the site, using the following land use categories:
1. All residential (single-family, one-or-two-family attached, multi-family, etc.) Leasing offices in multifamily developments shall count towards residential use calculations.
2. Commercial/industrial.
3. Institutional/dedicated public parks (e.g. hospitals, schools, churches, government buildings, dedicated public parks and the likes).
4. Mixed-use buildings (a mix of residential and non-residential within the same building, meeting the percentage requirements defined in subsection (d)(7)a.
c. Parking facilities and private open spaces shall be classified the same as the primary land use they serve.
(4) Proximity test. Developments that are 90% or greater residential uses must perform a proximity test to ensure a mix of uses in the surrounding area. No development that comprises 90% or greater residential uses shall be permitted unless the Director, determines one of the following:
a. The residential land use category within a 1,320-foot radius of the proposed project site boundary, shall not occupy greater than 70% of the total land area. The proposed development shall be included in the calculation of this percentage. The land use area percentages shall be based on the current land uses and calculated using land use information obtained from the applicable tax appraisal district, site visits, or property research; or
b. There are demonstratable unique site conditions (e.g. adjacency to natural features, freight yards, etc.) make compliance with the conditions of section i above impractical in certain areas of the development site.
(c) Uses. In the MU-1 District, no building or land use shall be used and no building shall be hereafter erected, reconstructed, altered or enlarged, nor shall a Certificate of Occupancy be issued, except in accordance with the use table in Chapter 4, Article 12, and the supplemental standards of Chapter 5. Residential, commercial, and institutional uses may occupy the same building lot.
(1) Building types. The following non-exhaustive list of conceptual building illustrations demonstrate the recommended building forms for the MU-1 District. Additional building types and configurations that comply with the intent and regulations of the MU-1 district are encouraged. All intent statements are addressed through development standards set out in § 4.1300 (d) through (h).
a. General commercial. A development type with nonresidential uses. Ground story spaces are flexible enough to accommodate a variety of nonresidential uses. Upper stories are used for offices and/or other types of compatible nonresidential uses.
b. Mixed-use shopfront. A development type with ground-story retail and upper-story residential and/or office uses.
c. Apartment/condominium. Multifamily residential development type that often shares a common entrance. Primary entrances are prominent and street-facing. An elevated ground floor for residential uses is recommended to improve privacy. Parking for an apartment/condominium building is allowed on the side or rear of the building, but the preferred method is at the rear of the building or within a parking structure. A townhouse form shall be considered an apartment/condominium when the homes are on one platted lot and not on individually platted lots with ground floor separate entrances to each unit.
d. One-family attached (townhouse). A two- or three-story building with two or more attached dwelling units consolidated into a single structure and platted into individual lots. An elevated ground floor for residential uses is recommended to improve privacy. A townhouse form is regarded as an apartment/condominium when on one platted lot and not individually platted lots with ground floor separate entrances to each unit.
e. Manor house. A building that has the appearance of a conventional single-family dwelling with three to five attached dwelling units consolidated in a single structure. Dwelling units within a building may be situated either wholly or partially over or under other dwelling units.
f. Two-family attached (duplex). A building with two dwelling units on an individual lot separated by a shared common wall. Dwelling units within a building may be situated either wholly or partially over or under other dwelling units.
