Smithfield City Zoning Code

17.81 MASTER

PLANNED COMMUNITY MPC ZONE

17.81.010 PURPOSE

The purpose of the Master Planned Community (MPC) zone is to encourage imaginative and efficient utilization of land, develop a sense of community, and ensure compatibility with the surrounding neighborhoods and environment. This is accomplished by providing greater flexibility in the location of buildings on the land, creating and consolidating open spaces, and clustering dwelling units. The regulations contained in this Chapter are intended to create vibrant, sustainable, and walkable neighborhoods with integrated streets, attractive landscaping and a mixture of housing options. An MPC is a residential development with a well-defined development theme which includes usable open spaces, diversity in lot design and housing types, a variety of amenities, and a well-planned circulation system. The combination of all these elements is necessary for the development of an MPC zone. An MPC is a zone which may be located in a variety of areas throughout Smithfield City, if it can be demonstrated that such a project will demonstrate and fulfill the goals of this Ordinance in that area.

17.81.030 DEFINITIONS

The terminology contained in this Chapter shall have those definitions found in SMC 17.04.070, “Definitions.” Acreage, Gross: The total amount of developable land in an MPC development. Land with slopes in excess of 30% shall be considered undevelopable and shall not be counted into the gross acreage when calculating the base density. Land with slopes below 30% and above 10% should have decreased density. Acreage, Net: The total amount of developable land, exclusive of any public or private right-of-way and parking.

Cluster Housing: Cluster housing is a development of at least four (4) or more homes, designed using various forms of architecture, in which the houses are arranged in relatively close groups around a central common space sharing site amenities such as parking and landscaping in a coherent site design, located either on a single lot or individually platted lots.

Common Area: All land, buildings and/or structures intended or reserved for the private use of the residents and owners of the development. Density, Base: The maximum number of residential units per acre of developable land outlined in this Ordinance, prior to the awarding of any density bonuses. Density, Bonus: The allowable units in excess of the base density, which shall be awarded when the project complies with the bonus density design requirements of this chapter.

Developable Land: Land under thirty percent (30%) slope which can effectively be used in conjunction with landscaping, recreational facilities, buildings, or parking. Land with slopes below 30% and above 10% should have decreased density. Driveway: A private, paved area used for ingress or egress of vehicles, and allowing access from a street to a building, structure, or facility. Dwelling: As defined in SMC 17.04.070

Five-plex: A multi-family home, arranged or designed to be occupied by five (5) families. The structure having only five (5) dwelling units under individual ownership on one (1) lot.

Four-plex: A multi-family home, arranged or designed to be occupied by four (4) families. The structure having only four (4) dwelling units under individual ownership on one (1) lot.

Open Space: An area of land within a development, located on a parcel independent of residential structures which is designed and intended for the use or enjoyment of the development’s residents, their guests and, possibly, the general public. Open space shall include improvements as necessary and appropriate for use as usable outdoor space or privately held common space, so long as the open space maintains its intended use. Open spaces should be interconnected within a development, using biking/walking trails and landscape. Stormwater facilities may qualify as usable outdoor space if the physical characteristics are functional as usable areas for the intended purpose of usable outdoor space. Private Open Space: Areas reserved for use by the development’s resident and guests. These areas must be clearly labeled as open space on the plat and all other associated legal instruments. Open spaces should be interconnected within a development, using biking/walking trails and landscape. A mechanism must be established to fund and maintain all private open space. Parking Lot Aisle: The traveled way by which automobiles enter and depart parking spaces. Aisle width standards are set forth in SMC 17.24.020 of this title. Parking aisles shall not be considered streets for purposes of this Chapter. Parking Lot: A paved open area, other than a street used for the parking of more than four (4) automobiles whether for free, or for compensation. Parking lots shall not be located within the required front, street or side setback.

Tri-plex: A multi-family home, arranged or designed to be occupied by three (3) families. The structure having only three (3) dwelling units under individual ownership on one (1) lot.

17.81.040 REZONE REQUIRED

While not all areas in Smithfield will be suitable for the MPC designation, it is intended that the MPC be used throughout Smithfield City. Those who wish to petition the City for a rezone of their property to an MPC shall follow the procedure set forth in SMC 17.08.040, “Rezones.” A preliminary site and landscape plan detailing the developer’s intent for the entire parcel under consideration for rezone and the subsequent phasing plan shall be submitted and reviewed as part of the rezone request. In evaluating a request for an MPC rezone, the Planning Commission and City Council shall consider the criteria outlined in SMC 17.81.050, “Development Standards.” If the rezone is approved with conditions, the preliminary plan must return to the city council, showing the proposed changes. Additionally, as part of the rezone request, a developer shall demonstrate to the Planning Commission and City Council how the proposal addresses and fulfills the specific goals and values related to architecture, site design and walkability, which are found in the Smithfield City General Plan and in the purpose statement of this Chapter.

The approved MPC rezone directly corresponds to the approved preliminary plan(s). If said plan(s) are altered, modified or unused another rezone must be completed using the standard rezone process. Changes to the approved plans which will prompt a city rezone include the following: plans that change the number or size of any new lot(s), the calculations of density bonuses, the location of approved amenities and any conditions set by the Planning Commission or City Council.

17.81.050 DEVELOPMENT STANDARDS

The following are the minimum development standards and regulations for an MPC zone. Developers are encouraged to go above and beyond these requirements, but these are the minimums required to obtain approval of an MPC.

  1. Project Size: An MPC shall not be less than fifteen (15) acres in size.
  2. Primary Use: An MPC shall be residential.
  3. Housing Types: Developers are encouraged to provide a mix of housing types in an MPC. Such types may include, but are not limited to single-family (detached, twin homes, cluster) and multi-family (tri-plex, four-plex, five-plex).
    1. Developers are required to have at least three (3) types of housing, two (2) of which must be single-family. Single-family detached housing must make up at least forty percent (40%) of the total housing units in the project but shall not make up more than sixty percent (60%) of the total housing units in an MPC.
    2. Developers may reduce the percentage of required single-family detached housing, in exchange for an increase in open space, as outlined in SMC 17.81.060. In no case shall the percentage of single-family detached housing be less than thirty-five percent (35%) of the total required housing units.
  4. Base Density: The base density shall be six (6) units per acre, exclusive of any property in the development which is needed for rights-of-way. Density bonuses shall be calculated by first determining the allowable number of units. The allowable number of units shall be calculated as follows: Net Acreage * 6 = Base # of dwelling units
  5. Single Primary Structure Required: Each lot may contain no more than one (1) primary structure. All the dwelling units on the lot shall be contained within that primary structure. No single structure may contain in excess of five (5) dwelling units.
  6. Lot Widths/Setbacks: The primary dwelling structure shall be set back from either the property line or right-of-way lines as shown below. (All measurements are in feet):

  7. Encroachment into the Setback:
    1. The ordinary projection of bay windows, chimneys, awnings, ornamental features, eaves and general building design projections, may encroach into any of setbacks, provided none of the encroachments exceeds twenty-four inches (24”) in depth.
    2. Unsheltered decks shall be allowed to project into the rear setback a maximum of ten feet (10’). In no case shall the unsheltered deck be built to a height greater than the uppermost floor level.
  8. Dwelling Unit Minimum Size: Each dwelling unit in an MPC shall contain a minimum of eight-hundred fifty (850) square feet of living space, and the ground-floor footprint of any building which contains dwelling units shall not be less than five-hundred (500) square feet per dwelling unit.
  9. Building Orientation:
    1. No residential dwelling structure in an MPC may face the rear of another dwelling structure on an adjoining/adjacent parcel/lot.
    2. Buildings with their front facing each other shall have a minimum of twenty-five feet (25’) between building fronts.
  10. Height Regulations: No primary structure shall be erected to a height greater than thirty-five feet (35’), the height being measured from the threshold (finish floor elevation) of the lowest main entrance to the highest point of the main building.
  11. Signage: Signage for the MPC should be coordinated and cohesive throughout the entire project. Signs shall comply with the requirements of SMC 17.36, “Signs.”
  12. Lighting: All lighting shall conform to SMC 9.24, “Outdoor Lighting.”
  13. Trash: All community trash containers shall be screened from public view and adjacent properties with a six-foot (6’) sight-proof fence or wall. The placement of trash containers and access thereto shall be reviewed and approved by the entity designated by Smithfield City to provide waste management services to the MPC. Unless otherwise required by the waste management provider, openings shall be oriented away from public view or screened with opaque gates and shall provide ease of access for trash collection. No trash containers or enclosures may be located within a required front or street-side yard setback, and no single family attached, or multi-family trash containers or enclosures may be located within setback.
  14. Parking:
    1. Each dwelling unit shall be required to have the following off-street parking spaces:


      Minimum Resident Parking Spaces Per Dwelling UnitGuest Parking Spaces Per Dwelling Unit
      Single-Family 2---
      Multi-Family20.50

    2. If calculating the required number of parking spaces results in a fraction, the next highest whole number of required parking spaces shall be required. (E.G., 3.25 = 4 required parking spaces.)
    3. In order to facilitate better design of an MPC, required off-street parking spaces may be grouped together; however, in no case shall more than twenty-five percent (25%) of the required parking spaces be grouped together. A professional parking study may be used to show acceptable alternate parking configurations.

17.81.060 OPEN SPACE

  1. Each MPC project shall consist of a minimum of five percent (5%) open space. The required amount of open space shall be calculated based on the net acreage of the property and shall be devoted to landscaping, preservation of natural features and resources, and passive and active recreational features.
  2. In exchange for an increase in the amount of open space provided, developers may reduce the required percentage of single-family detached housing. The reduction shall be equal to the increase in open space (i.e. an additional 5% open space would decrease the required single-family detached housing to 35%.) In no case shall the single-family detached housing drop below 35% of the total required housing units.
  3. The open space shall be defined as private or common open space for the enjoyment and use of the development’s residents or the general public.
