Comprehensive Plan and Zoning. The Comprehensive Plan guides this area for low - density residential and uses. The site area is zoned R -1 Single Family Residential District. The purpose of the R -1 District is to provide for low density single family detached residential dwelling units and directly related complementary uses. In review of the proposed subdivision, the overall layout and proposed single - family uses meet the intent of the R -1 District and the policies of the Comprehensive Plan. Density. The proposed gross density for the site is approximately 2.55 units per acre. The Low Density Residential land use classification allows up to 4 units per acre. As such, the proposed density for the R -1 plat is appropriate. Lot Area and Setbacks. The following chart illustrates the performance requirements for the R -1 District, as well as what is proposed for the site. As some variation in lot configurations is proposed, the information provided reflects the minimum proposed for the proect: With the exception of the lot width on Lot 6, the proposed plat is consistent with the performance requirements of the R -1 District. When measured at the required setback line, the width of Lot 6 appears to be approximately 73 feet, two feet short of the minimum requirement. As such, a slight adjustment shall be required to achieve the minimum lot width. Streets and Access. Access to the site will be provided off Old County Road C, in the southwest corner of the site. The street right -of -way is platted at 55 feet in width, with a paved surface 30 feet in width. This street will end with a cul -de -sac on the south side of Lots 5 and 6. The proposed cul -de -sac is approximately 320 feet in length, within the parameters allowed. The street width narrows as it circles this area, with 22 feet of paved surface. The center of the cul -de -sac will contain an unpaved area approximately 60 feet wide with a rock retaining wall and an infiltration ponding area. A similar design was proposed with the previous plat. On the previous plan submitted, this area was to contain landscaping. It is not clear whether plantings are proposed in the center with the new application. The turnaround area may be an issue for public works and general snow storage. Therefore, the overall street design and layout is subject to the review and approval of the City Engineer and Public Works Director. 2 R -1 District Requirement Proposed Lot Area (Interior) 10,000 square feet 11,193 square feet Lot Area (Corner) 11,000 square feet 11,597 square feet Lot Width (Interior) 75 feet 73 feet Lot Width (Corner) 80 feet 82 feet Front yard setback 30 feet 30 feet Side yard setback (interior) 7.5 feet 7.5 feet Side yard setback (corner) 30 feet 65 feet Rear yard setback 30 feet 35 feet With the exception of the lot width on Lot 6, the proposed plat is consistent with the performance requirements of the R -1 District.
