Sec 17.8.112 Adequate Public Facilities Required

  1. Adequate public facilities required. Adequate public facilities are and shall be required to be available concurrent with subdivision approval.
  2. Applicant to provide data. From and after the effective date of this amendment to the Development Code of American Fork City, Utah, no application for subdivision approval shall be granted, approved or issued unless the applicant has provided sufficient information or data to establish that essential public facilities in the area affected by the proposed development will have adequate and sufficient capacity available at the adopted level of service standards to accommodate the proposed development at or within a reasonable period of time following the granting or issuance of final plat approval for the proposed development. This shall be known herein as "adequate public facilities" requirement.
  3. Essential public facilities. Essential public facilities to which this requirement will apply include the following:
    1. Culinary waterworks system, including quantity, quality, treatment, storage capacity, and transmission/distribution system capacity;
    2. Sanitary sewer and wastewater system, including outfall lines, laterals and collector lines;
    3. Storm water drainage, including flood control facilities;
    4. Street system, including streets, roads, highways, intersections, and related transportation facilities; and
    5. Recreational facilities, including parks and trails.
  4. Procedures. As part of the material submitted in support of an application for subdivision approval, the applicant shall submit sufficient information to demonstrate that essential public facilities will be available at specified levels of service at or within a reasonable period of time following the issuance of subdivision plat approval for the proposed development. Such a determination may include the timing, phasing and sequencing of the proposed development. Compliance with level of service standards shall be measured in accordance with the adopted level of service standards as set forth in the city's general plan, as well as any ordinances, resolutions, policies, and regulations of the city pertaining to level of service standards as may from time to time be adopted. The city engineer, the city planner, the planning commission, and the city council, or any of them, may request additional information from the applicant to address the adequacy and availability of public facilities referenced above as part of the subdivision approval process.
  5. When adequate public facilities are not available. If it is determined that essential public facilities will not be available at the specified levels of service at or within a reasonable period of time following the insurance of final subdivision plat approval, so as to ensure that such services will be available at the time of occupancy of the new development being proposed, the city council—in the exercise of its discretion—may review, evaluate and discuss with the applicant, the following alternatives and conditions:
    1. Allow the developer to voluntarily advance the costs necessary to provide those public facilities which are necessary to service the proposed development and to meet the applicable level of service standards by entering into an appropriate form of development agreement, which may include, as deemed appropriate, provisions for credits or reimbursement of any expenses incurred above and beyond those reasonably necessary for or related to the need created by or benefit conferred upon the proposed development;
    2. Require timing, sequencing and phasing of the proposed development consistent with the available capacity of public facilities;
    3. Defer final plat approval and the insurance of building permits until all necessary public facilities are adequate and available; or
    4. Deny subdivision plat approval at the present time and require the applicant to reapply when adequate public facilities are available at the adopted level of service standard.

Sec 17.8.113 Derelict Parcels Prohibited

No subdivision plan/plat shall have the effect of creating a derelict parcel. Any such parcel must be attached to adjacent lots rather than allowed to remain as an independent parcel. Privately owned protection or retainer strips shall not be permitted. For purposes of this section, a derelict parcel shall be construed to mean:

  1. A residual parcel of land created or proposed to be created as part of a proposed subdivision of a larger tract, which parcel has insufficient area or dimension or possesses other condition(s) which prohibit its qualification as a zoning lot within the zone.
  2. Any parcel directly adjacent to the proposed subdivision, under the same ownership, which parcel having insufficient area or dimension or possesses other conditions which prohibit its qualification as a zoning lot within zone. Any such parcel shall either be incorporated into the design of the proposed subdivision or disposed of so that a derelict parcel no longer exists.

Sec 17.8.114 Unimproved Residual Lots Not Permitted

No subdivision plan shall have the effect of leaving a residual zoning lot for which the required subdivision improvements: (1) have not been previously constructed or, (2) are not to be included as part of the required improvements for the proposed subdivision. For purposes of this paragraph a residual zoning lot shall be construed to include a parcel created by the proposed subdivision but not included as a lot on the final plat, which qualifies as a zoning lot, but because of insufficient size, dimension or other limitation is not readily capable of further division in accordance with the requirements of the zoning ordinance.
(Ord. No. 2000-6-17)

Sec 17.8.201 Subdivider Confers With Development Review Committee

  1. The subdivider may meet with the Development Review Committee in a pre-application meeting to discuss the basic concept of the proposed subdivision and to obtain information pertaining to the general plan and zoning classification of the area proposed for subdivision, city requirements and standards for design and construction of streets, utilities and other requirements affecting the land proposed to be subdivided.
  2. The purpose of the conference(s) is to provide informal assistance to the subdivider in the preparation of the plans early in the process. The Development Review Committee may suggest changes in the proposed layout so the project is more fully consistent with the city's general plan and also with the city's development regulations and policies. The recommendations from the Development Review Committee prior to the subdivision application shall be purely advisory and in no way shall the conference be construed to constitute approval of the plan.

      2. The length of the reduced segment will not be more than eight hundred feet;
      3. The reduced right-of-way width does not create a safety concern; and
      4. The elements of the right-of-way are in conformance with the General Plan of American Fork and the Bike and Pedestrian Master Plan for American Fork City.
    2. Partial width streets. The city may approve a subdivision project having partial width streets along one or more of the project boundaries, subject to the following terms, conditions and findings:
      1. The partial width street is located at the boundary of the proposed residential subdivision project.
      2. The partial width street will have a minimum width of right-of-way of thirty-five feet and will include the construction of all required street and utility improvements in accordance with city standards for partial width streets.
      3. The adjacent parcel is undeveloped, but its reasonably capable of further development in a manner that will result in the remainder of the street being dedicated and improved.
      4. The partial width street will be less than four hundred feet in length and will serve as the primary vehicular access route to not more than ten residential lots.
      5. Title to the right-of-way for the partial width street will be conveyed to the city as part of a final plat dedication or other acceptable means of conveyance.
