3) Interim permitted. None. c) Prohibited uses. All other uses not listed in subsection (a) or (b) of this section are hereby prohibited. d) Use restrictions and allowances. The final PUD overlay district ordinance for an open space PUD may include specific provisions governing uses which supersede underlying zoning and the general PUD regulations herein. 105.12.1050 Open Space PUD Design Open space PUDs shall comply with all of the following minimum design standards unless modifications are authorized for consideration by the city council via a super-majority vote. a) Density. The maximum dwelling unit density within an open space planned unit development shall be 18 32 units per 40 acres of buildable total land area (0.45 0.8 dwelling units/acre) on the undeveloped parcel. A development without at least one access onto a roadway classified as a collector or greater shall have a maximum density of 0.45 dwelling units per acre.; however, Tthe total number of dwelling units shall not exceed the density limitations contained in the comprehensive plan for open space preservation development. In addition, the applicant shall submit the proposed density based on buildable land area for comprehensive planning purposes. b) Lot design. Lot locations and configurations within open space planned unit developments shall be derived utilizing the following methodology. An applicant must be able to demonstrate how these steps resulted in the plan being proposed. 1) Soils analysis conducted. A certified septic designer or soils scientist shall complete a review of the soils on the site, and categorize all areas as highly suitable for septic systems, moderately suitable for septic systems, or poorly suited for septic systems. 2) Septic design identification. Based on the soils analysis, an applicant must identify whether the proposed development will be serviced by individual septic tanks and drain fields, or via a system of individual septic tanks which utilize one or more communal drain fields. a. If individual septic tanks and drain fields can be supported by the available soils and is the chosen methodology to serve the development, all proposed lots must be able to provide primary and secondary drain field sites on each lot (outside of drainage and utility easements), and must meet the minimum lot size standards outlined herein. b. If individual septic tanks which utilize a communal drain field (or fields) is the chosen methodology to serve the development, then the locations for communal drain fields shall be identified within the areas deemed the most suitable on the site for supporting septic utilities according to the soils analysis. All such areas shall be clearly denoted on provided plan sets. c. Low pressure sewer should only be allowed in special circumstances as deemed necessary by the city engineer. When low pressure sewer is deemed necessary by the city engineer, it must be installed outside of the street pavement such that street excavation is not required for repairs or replacement. 3) Identification of required buffers. No build zones from each property boundary shall be derived as follows: A no build zone (buffer) between the proposed buildable lots and the PUD boundary shall be derived as follows: a. A 200-foot buffer from all adjacent property lines that abut an existing residential development or a parcel of land not eligible for future development as an open space planned unit development due to insufficient parcel area. b. A 100-foot buffer from all adjacent property lines that abut land that is eligible for future development as an open space planned unit development. c. If the development site is adjacent to an existing or approved OP development, the required buffer shall be equivalent to the buffer that was required of the adjacent development (See LEC 105.12.170(b)).
