Sketch Plan Review: The Village of Sunfish Lake January 31, 2003 Page 2 of 6 Ramsey Comprehensive Plan designates this area for Iow density single family residential development not to exceed a net density of 3 units per acre or up to 4 units per net acre if townhomes are proposed as part of a Planned Unit Development (PUD). Therefore, the density shown on the site plan is acceptable. Access and Streets: The subdivision proposes, two connections wi{h Sunwood Drive. Street B intersects at 145th Ave., while Street D intersects roughly halfway between 146th Ave. and Potassium S't. In the southeast corner of the plat, Street'A connects with the existing stub of I46th Ave. west of Potassium St. The submitted preliminary plat does not show a connection to the northern e,-ctension, of Tungsten Way. Since that original submission, staff has received a revised drawing showing the Tungsten Way connection being made. A traffic impact analysis was prepared for tNs subdivision by Benshoof & Associates. A summary of findings of the study are contained herein. The subdivision will generate 1,168 trips in a 24-hour period (584 entering and 584 exiting) vehicle trips daily. The majority of' these trips will be handled by Sunwood Drive going eastbound and westbound. The two connections to local streets (Tungsten Way and 146th Ave.) will' see little traffic impact. For example, the intersection of Tungsten Way and 1454 Ave. handles 13 vehicles during the peak morning hour. The development wilt increase the peak hour traffic by an additional 6 vehicles. During the afternoon peak hour, 28 vehicles travel through the intersection. This subdivision will add an additional 6 vehicles during the afternoon peak hour. The intersection of 146t~ and Potassium currently handle 25 and 30 vehicles in the' morning and afternoon peak hours respectively. The proposed subdivision would add 9 and 12 vehicle trips through the intersection during the morning and afternoon peak hours respectively. The City's Engineering, Public Works, Police, and Fire Departments have reviewed the proposed road widths serving the development. The submitted plans show 26': feet wide public streets within 50-foot right-of-ways. City standards are 32 feet of constructed road as measured from back of curb to back of curb and 60 feet of public right-of-way. All of these Departments find the 26 feet width unacceptable and will require the streets to be 32 feet wide for public safety and'traffic movement efficiency. The proposed 50 feet right of way;. however, is acceptable due to the unique nature of the proposed development. Language will need to be contained in the development agreement that will allow .the City's snow plows to. push snow onto the properties of the single-family homes. The cottages are shown as having a public road that is 26 feet wide that branches off into 16 feet wide one-way corridors. All' of the City's Departments dealing with public safety find these road widths.unacceptable. You have submitted a plan revision that shows the cottages being served by a. private street 24 feet wide with one-way corridors that are 16 feet wide. Given the nature of the proposed development and the fact that. the subdivision is proposed to be a PUD, staff finds this configuration acceptable as long as parking is not permitted on the private streets. Lot Size and Dimensions: Current regulations require that urban single family homes be located on lots of at least 10,800 square feet in size. The proposed development shows, single family homes being located on lots ranging from 5,460 to 8,500 square feet. In the 92 '
