Sec. 117-110. Residential development transitioning. <br />(a) Purpose. The purpose of this section is to require a residential development transition plan in order to <br />promote orderly transition between residential developments. The historical platting of lands for urban and <br />rural residential development has created character elements that are difficult to intermingle when the land <br />use densities vary. This section provides techniques to mitigate lot size and density impacts between <br />residential developments. <br />(b) Transitioning. The term "transitioning" for the purposes of this section is defined as the lot density change <br />between one residential development and another. <br />(c) Transitioning options. Transitioning options are available to facilitate the best possible land use and <br />development pattern between new residential developments with adjacent residential neighborhoods. The <br />following is a list of transitioning techniques that may be used to create reasonable transitioning between <br />existing residential neighborhoods and new developments. The city shall determine which options are <br />acceptable means to provide for the transitioning. Developers that are required under this section to provide <br />transitioning may seek guidance from the city prior to preliminary platting via a formal sketch plan review <br />process or by informal city approved means. Transitioning options are as follows: <br />(1) Natural features. Natural features described in this subsection (c)(1) are available to be used as <br />transitioning between existing single-family residential neighborhoods and proposed residential <br />development with higher densities. <br />a. Existing topographical features such as hills and swales. <br />b. Wetlands, lakes, rivers, and streams. <br />c. County and state highways, or Metropolitan State Aid (MSA) collector streets. <br />d. A minimum 300-foot-wide, undeveloped, natural distance separation that will not be eligible for <br />future development. <br />(2) Landscape buffering. Landscape buffering is a technique available for transitioning between existing <br />single-family residential neighborhoods and proposed residential developments with higher densities <br />that uses either existing or newly planted vegetation. <br />a. Determination of buffering attainment level. <br />1. Proposed urban development adjacent to existing urban development. This subsection <br />applies to proposed urban residential developments that are adjacent to an existing single- <br />family urban residential neighborhood. Matching the proposed residential development to <br />the adjacent existing neighborhood in the following chart determines the level of buffering <br />or "attainment" required. The numeric attainment level is matched to the level found in <br />the chart in subsection (c)(2)b of this section. <br />Proposed Use <br />Transition Attainment Level <br />Existing Adjacent Urban Use <br />Vacant R-1 Zone <br />R-1 Zone NA NA <br />R-2 Zone NA Level 1 <br />R-3 Zone NA Level 2 <br />PUD Zone NA As determined necessary by the <br />city <br />(Supp. No. 11, Update 2) <br />Created: 2022-10-04 16:03:40 [EST] <br />Page 1 of 3 <br />
