06.080 Allowed Density

A. The base density for all residential development in the PC Zone shall be based on the current General Plan land use designations or three units per acre, whichever is greater. Density is calculated based on the gross acreage of the entire PC Zone area, including commercial and residential areas, to produce a total number of allowed units. Commercial area equivalent residential units shall be calculated at three units per acre. Areas of steep slopes, wetlands, or areas below the high water level of Utah Lake as defined in Section 12.060-K of this Code as well as any existing public streets, any areas of additional right of way required to comply with the Lehi City Master Transportation Plan, and any perennial channels, measured from top of bank to top of bank of the flow channel, shall be excluded from the gross acreage when calculating the base density. Density for any areas under existing power transmission lines shall be calculated at 50 percent of the allowed density. Density shall not exceed the overall base density of three units per acre or current General Plan designations unless specifically authorized in an approved Area Plan and in accordance with the density bonus provisions described in this chapter. Units may be applied to the area in a manner which meets the purpose of this chapter, provides a mixture of housing types and configurations, and is subject to the approval of an Area Plan for the Planned Community. Additional density may also be allowed as part of a transfer of development rights from any environmentally sensitive areas outside of the proposed Planned Community. B. The overall average residential density requirement is intended to set a baseline density standard for all residential development, as well as encourage variety, and allow flexibility to respond to changing market conditions. A mix of housing types may be used to achieve this criterion, some high density and some low density, provided the overall average density is met. For example, a planned community may include a mix of large lot single family units of two dwelling units per acre, traditional lot single family units of 3.5 dwelling units per acre, small lot single family units of 5.5 dwelling units per acre, townhouses of 8 dwelling units per acre, and apartments of 12 dwelling units per acre combined to meet the overall allowed density. C. For the purposes of administering this chapter, the Area Plan shall identify and delineate each different residential area as a “sub-area” or “pod”, with an indication of the number of units per acre allowed in each sub-area.
