Ord. 2019-1149-O, 12-3-2019; Ord. 2024-1251-O, 2-25-2024; Ord. 2026-1318-O, 3-17-2026)

10-9-4: GENERAL PLANNED DEVELOPMENT STANDARDS AND REQUIREMENTS:

All planned developments shall meet the following standards and other requirements as set forth:
   A.   Permitted Uses: All uses must be approved in conjunction with the project plan and in accordance with the use chart approved as part of the PD. If requested zone change is to PDC, in addition to any approved use chart all uses must be in accordance with the Use Matrix in section 10-10-2.
   B.   General Standards And Requirements:
      1.   Preservation Of Features: The development shall be compatible with the existing topography of the land and shall reserve unusual topography and natural features. Requests to waive this standard must be accompanied by a professionally prepared feasibility report indicating why the proposed development is a significant county need that transcends the need to preserve the topography and/or other features.
      2.   Land Disturbance After Concept Plan Submittal But Prior To Project Plan Approval: No alteration or disturbance of land in a planned development zone, or the natural, or cultural resources thereon, shall be permitted until the zone change, complete project plan, and construction drawings have received approval from the county. Any subsequent land disturbance must be consistent with the approval granted by the county commission.
      3.   Subdivision Regulations: Land within a planned development, or a phase of a planned development, shall be treated as a subdivision and thus subject to the provisions of the county subdivision ordinance.
      4.   Interconnectivity Of Land Use/Phases: Each phase of the project shall not be isolated from adjacent land development and connection to future development shall be identified and maintained. Each phase of the project shall be served by at least one (1) adequate dedicated public roadway that connects to all adjacent phases or land use areas. If the project has more than fifty (50) units, the overall project must contain a minimum of two (2) public roadway accesses. Any deviation from these required two (2) primary accesses must be recommended by the land use authority and approved by the county commission and only if the unit count is seventy-five (75) units or less.
      5.   Calculation Of Density: Land uses for open space, common areas, and interior streets, drives, sidewalks and other circulation ways may be included as part of the density calculation. The amount of land characterized by floodway, steep slopes (as defined by the county hillside ordinance), wetlands, unstable soils, or other unbuildable or sensitive lands may not be included as a part of the land area for density calculations. However, twenty percent (20%) of the unbuildable land area may be applied to the buildable portion of the property through density transfer to increase the net density of the project. Within phases, density for a specific phase may not exceed that permitted in the project plan for that phase, and the overall density for the project at all times must be less than or equal to the allowable maximum density.
      6.   Streets And Public Infrastructure: Water, sewer, street, electric, and other required infrastructure shall be provided according to the requirements of the county subdivision ordinance and county construction and design standards. Exceptions to the county standards and subdivision requirements related exclusively to roadway design standards and layout must be supported by appropriate engineering studies and approved by the county commission pursuant to its approval of the project plan, and shall control and regulate the development and construction within the project as guidelines and standards specific to the project. This provision does not alter the public access requirements above. The following infrastructure requirements are required as a part of all PD developments.
         a.   Design Of Streets: The design of streets is subject to recommendation by the land use authority and approval by the county commission, which may require or allow modifications to the location, layout, or capacity of roads, or attach additional requirements such as turn lanes, traffic circles, wider or narrower right-of-way; pavement widths, medians, traffic calming features, etc., and provided that such modifications meet generally accepted traffic engineering and planning principles that can be justified by the applicant (as may be done via traffic engineering studies) and verified by the land use authority. The county may retain independent traffic engineering professionals under its control and supervision to verify or modify the applicant's proposed street designs, at the applicant's expense.
         b.   Interior Streets: Interior streets and roads will be owned and maintained by the county unless otherwise recommended by the land use authority and approved by the county commission. Prior to any agreement by the county to own or maintain streets, streets must meet the county specifications and must be approved by the county public works department.
         c.   A traffic study must be submitted for any commercial project, multifamily project, and for every residential project that has over ten (10) dwelling units. The traffic study shall address all potential impacts, including but not limited to, modifications needed to intersections of roads leading to the project, adequacy of the access roads to handle traffic in all weather conditions, right-of-way status, internal circulation, connectivity with adjoining properties, access safety, and emergency services accessibility.
      7.   Interconnectivity Of Trails, Paths And Sidewalks: Sidewalks shall be provided according to the requirements of the county subdivision ordinance in all commercial, multifamily, and all residential developments with a density of more than one (1) residence per acre. Each phase or development shall be connected to existing or planned pedestrian paths and sidewalks and must maintain already-existing public access to recreation. Wayfinding signs, kiosks and/or trail markers may be required as necessary to guide public access.
      8.   Parking: Parking stalls and lots must conform to chapter 10-16 of this code. Any variation must be approved by the planning commission.
      9.   Temporary Storage Containers: May be allowed in PD developments as permitted by Community Development staff.
      10.   Utilities: Construction drawings for all utility systems shall be reviewed and approved by the county public works department prior to commencing the installation of any system, and prior to final approval of a subdivision plat or a project plan done where a subdivision plat may not be necessary. Comply with county ordinance 10-5-3. All applicable will-serve letters and any required feasibility studies must be approved prior to project plan or zone change approval. Additionally:
         a.   Water: For developments served by state regulated/approved water companies, in which the developer has no financial interest in the water company, a letter from the water company agreeing to provide the amount of water required by the development is required with any zone change application.
            For all new development in which the developer has any interest whatsoever in the water company providing water to the subdivision, a letter from the Utah State Department of Environmental Quality, approving the quantity, quality and feasibility of providing culinary water to the project is required prior to any zone change and project plan approval.
         b.   Sewer/Septic: A letter from Utah Department of Environmental Quality and the Southwest Utah Public Health Department, whichever agency is applicable, and a letter from the appropriate sewer authority for approving the method of wastewater disposal to be used in the development is required prior to project plan approval. The method of disposal must also be approved by the planning commission.
         c.   Fire: A fire protection plan that complies with section 11-5-4 of this code must be reviewed by the applicable fire district.

Each phase shall require separate preliminary and final plat approval using the procedures set forth in title 11 for the type of use in each phase. Phase plans must be submitted with the project plan and zone change. The phase plan must be consistent with the project plan and shall meet all requirements of the subdivision ordinance for a preliminary plat.
      1.   Preparation Of Phase Plan: The phase plan shall be prepared by a registered land surveyor, or engineer and meet all requirements equivalent to a preliminary plat.
      2.   Submittal Of Phase Plan: After a phase plan is submitted and the staff has determined that all of the necessary information has been submitted, the plan shall be placed on the next available land use authority agenda to be reviewed with the project plan and zone change. If the project is to be developed in more than one phase, each phase of the development shall be submitted for separate preliminary and final plat approval.
   D.   Rezoning: The zone change request to the applicable PD (Planned Development) zone and required public hearing take place in conjunction with the review of the completed project plan and phase plan. The applicant shall submit a zone change application requesting a zone change to a planned development zone. The project plan shall be reviewed by staff and discussed in an informal meeting with the applicant to examine potential areas of nonconformity. Staff, upon review of the plan, will determine whether the project meets the intent of the PD zone and includes the required elements. Staff may reject the project plan and notify the applicant of any deficiencies so corrections may be made. However, should the plan meet the intent and contain the required elements, staff will accept the project plan and provide the applicant with suggestions for changes and modifications, if any, that will prepare the applicant for the submittal to the recommending body and land use authority. If the project is of such size that it is considered in one phase for subdivision, the staff will also review the project plan for conformity with the preliminary plat requirements of the subdivision ordinance. While the applicant may request more than one review of the project, one project plan review, in the form of an advertised public hearing is mandatory. For a PD zone change or PD amendment. the planning commission is the recommending body to the county commission.
      1.   Planning Commission Review Of The Project Plan, Phase Plan, And Zoning Application: After staff officially accepts the project plan (completed application and full review by the staff) the project plan will be properly noticed for the required public hearing and will be placed on the next scheduled planning commission agenda in which the noticing requirement can be met. The planning commission will review the project plan and make a recommendation on the project plan and the rezoning of the property to the county commission. The planning commission will review the project plan to county standards and this title and will consider the following:
         a.   How the proposed project plan meets the purpose of a planned development;
         b.   The overall project density as well as the density of land use components, land use mix and percentages; and
         c.   General vehicular and pedestrian circulation including the location and capacity of the facilities and connections internally and externally, and open space type, amount, and location.
      2.   County Commission Review Of The Project Plan, Development Agreement, Phase Plan, And Zoning Application: Upon receiving a recommendation from the planning commission and before enacting an amendment to the land use ordinance (zone change), the project plan shall be presented before the county commission. Phase plans will then be developed according to the project plan of the applicant. The project plan and the zone change to a PD zone must be approved concurrently.
   E.   Site Plan: The site plan shows the development plan for individual building sites within a specific phase. If there is to be only one phase to the project, and all buildings are to be located on one legal parcel, a single site plan for the entire project will be permitted.
      1.   Site plans must meet all of the requirements for site plan review, which includes all requirements from the subdivision ordinance that may be necessary in order to properly process the request.
      2.   Single-family residential lots are not required to submit a site plan for land use authority review; however a site plan will be needed for a building permit. This does not apply to a PD-STR project.
      3.   Site plans for commercial or multi-family residential lots shall be submitted to the land use authority for individual parcels within a phase. More than one building may be contained on an individual parcel. Site plans must also contain the following items:
         a.   Landscape plans;
         b.   Location of all buildings; and
         c.   Typical elevations.
   F.   Construction Drawings And Required Studies: Following the approval of the project plan and zone change by the land use authority, the applicant shall submit two (2) sets of paper construction drawings and one (1) electronic copy (PDF) to the community development department, along with all studies and reports required by the county standard specifications for design and construction. Construction drawings and all required studies and reports will be reviewed for compliance. Once approved, three (3) finalized copies twenty-four inches by thirty-six inches (24" x 36"), one eleven inch by seventeen inch (11" x 17") and one (1) electronic copy (PDF) shall be submitted for stamp of approval.
   G.   Final Plat Approval: If land subdivision was required for a phase or land use area, the applicant shall submit an application for final plat approval using the criteria and procedures required under the subdivision ordinance. Final version of CC&Rs, development agreement, details and exhibits shall also be submitted at this time to allow the county to determine that there are inconsistencies with the land use ordinance.
   H.   Subsequent Phases: If the project is phased, each phase shall be submitted according to the same requirements as the initial phase.
   I.   Minor Amendments To The Project Plan: The land use authority that approved the project plan may consider approval of amendments to the project plan provided that:
      1.   The applicant submits a revised set of plans detailing the proposed change.
      2.   The change involves no more than a five percent (5%) increase in residential density.
      3.   Involves no more than a five percent (5%) decrease in parking allocations.
      4.   Involves no more than a five percent (5%) increase in nonresidential floor area.
      5.   Involves no more than a five percent (5%) modification to any other measurable project criteria.
      6.   The proposed change meets all of the requirements and provisions of this section.
      7.   The proposed amendments do not alter any approved site development regulations of the plan and do not materially alter other aspects of the plan, including traffic circulation, mixture of use types, or general physical layout.
      8.   Any proposed amendments, not conforming to these provisions shall be considered a significant change and shall be resubmitted as a PD amendment (zone change amendment) with a revised project plan and preliminary plat. Any proposed amendments which do not meet the standards or other provisions of this chapter shall first be considered by the land use authority and recommended to the county commission for either approval, modification, or denial.
   J.   Setback And Height Standards: The setback and height minimums and maximums listed in table 1 of this section are intended to serve as a guide to the land use authority, the county commission, and the developer in reviewing the standard requirements for development throughout the county. Realizing that a specific planned development plan may vary from these standards through innovative and creative design, the county commission, upon recommendation from the land use authority, may adopt modifications to the above specifications as they see fit in order to provide harmony within a PD zone as may be requested by the developer. Items of a life/safety nature (i.e., building separation as per fire code, and building code requirements) may not be modified. However, other elements of the plan may be approved according to the specific development plan, map, and text being considered as a part of the PD zone change approval. Modifications for one particular PD zone request do not set precedent for any other PD project. Each project shall be reviewed independently from any other project.

* A verifiable moderate income housing unit (MIHU) is defined as a deed restricted unit on a form provided by the county and under terms acceptable to the County Attorney's office ensuring that the newly constructed unit remains owned by and affordable to low or moderate income households for a period of not less than 25 years. Each unit shall be owner-occupied, with a primary residential exemption as determined by the Washington County assessor's office, with no right to short term rent the unit or any portion of it. Income qualifications for a MIHU are based on federal tax returns showing that the household earns less than or equal to 80% of the area median income (AMI) in Washington County. The deed restriction shall be enforceable by the county through legal and equitable remedies. Any lender or mortgage holder shall execute a subordination agreement acknowledging subordination to the deed restriction. In the event of foreclosure or trustee's sale, the county will release the deed restriction upon reasonable request. All other sale or transfer events are subject to the deed restriction to ensure the prospective purchaser and unit remains affordable for the required time period. For a MIHU in a development with a property owner's association (POA), the MIHU shall be inside the POA for purposes of common area use, but no POA fees may be assessed or collected against the owners or units. For all MIHU, the county in its sole discretion, may reduce minimum lot size or dwelling size standards, compared to others in the PDR, to promote affordability if the primary goal of having the lots and dwellings harmonize with all others is met. No garage requirements apply to a MIHU, and shared access also may be considered by the county.
