The most"substantial setback deviation is the 20 foot minimum separation distance between buildings in the R-2 District. This seems to be excessive in lieu of the fact that single family homes can be constructed with a 12 foot separation and still meet City Code. The 20 foot separation in the R-2 District was written with the larger, multiple-unit buildings in mind; it did not anticipate the detached townhome style. From a fire safety standpoint, it is preferred to obtain a minimum of 10 feet between buildings. The applicant has been requested to revise the plat to this minimum distance between homes. City Code discusses general and specific requirements for allowing zoning amendments to Planned Unit Development (PUD). These criteria are as follows: High Quality Desizn and Compatibility with Surroundin~ Land Uses The proposed detached townhomes will include architectural elements resembling prairie-style homes. They are proposing to meet the architectural standards required in the R-2 district. Staff is recommending the use of varied colors among the units, to increase the street appeal of the development. The surrounding land uses are townhomes to the south and single family homes to the west. While density transitioning will be required, it appears as though detached townhomes are a good fit between the two land uses. Provision of a Wider Ranae of Housina Types, Prices Ranaes. and Styles The application is proposing to construct one-level, association-maintained living. This is a newly emerging housing option targeted for primarily empty-nesters and seniors. The houses are proposed to be prairie-style, and incorporate a variety of unique design elements. Public Amenities and Open SCaces Planned-Unit-Developments require 50% private or 20% public space. It appears as though the proposal meets the 50% private open space requirement. The total impervious surface, at full build-out, is .83 acres, which leaves 53% to open areas. This development will provide another extension of the trail system in the City, providing a link that will eventually connect trail from County Road 47 to Alpine Drive. Preservation of Natural Amenities and Scenic Qualities It does not appear that there are any significant natural amenities or scenic qualities to this site, with the exception of its wooded characteristics. Efforts should be made to retain as many trees as possible, especially throughout the density transition area. Staff recommends that, as part of the PUD approval, the tree preservation plan is revised to preserve more trees as a natural amenity and density transition. 20
