Preliminary Plat: GAD's Prairie May 24, 2006 Revised June 23, 2006 Page 3 of 6 The traffic generation analysis conducted for this proj ect calls for the installation of a stop sign at Nowthen and proposed Helium Street. No other improvements have been identified in the analysis, with the exception of the consultation of Anoka County. \ . Access and Streets: The plat proposes to gain access off of County Road 5 (Nowthen Boulevard). The Anoka County Highway Department is currently reviewing the request for access, as proposed by the plat. Any approvals will be contingent upon addressing the access and traffic concerns from Anoka County. Comments from Anoka County should anticipate the construction of turn lanes on the county road. Proposed Helium Street is platted as a public street, with a service road right-of-way to 45 feet instead ofthe standard 60 feet. However, the paved surface will remain a standard 24 feet. This is generally acceptable to City Staff because of the proximity to County right-of-way and the lack of necessity to construct a sidewalk. However, a trail will be required to be located along Nowthen Boulevard. The installation of a temporary cul-de-sac is required on all residential subdivisions, to allow adequate turning provisions for residential, public works, and emergency vehicles. Please revise your plat to indicate construction of this turning provision. The driveway of Lot 1 is less than 15 feet from the edge of the temporary cul-de-sac pavement. This will be problematic particularly for the plowing of snow relative to this lot. This lot may be platted as an outlot or the configuration of the cul-de-sac may be revised to address this issue. Please submit a revised plat that addresses this issue. Helium Street must be constructed with curb and gutter, to urban street standards outlined in City Code. Easements: Drainage and utility easements are required over all areas held m common ownership. Please revise your plat to reflect this. . Density Transitioning: The preliminary plat proposes to construct townhomes adjacent to single-family homes, and requires density transitioning. City Code allows a variety of measures to satisfy the density transitioning requirements, including landscaping, benning, and holding in land in common ownership. If land~caping is proposed, then Level 1 transitioning is required. A minimum of six trees for every 100 feet of adjacent property, including two each of evergreens, over-story trees, and ornamental trees, are required along the western boundary of the parcel, for a total of 12 trees to be used for transitioning. It is preferable to use existing vegetation to satisfy the density transition requirements where feasible. Please submit revised landscaping/tree preservation plans that indicate these trees within the density transition area. Landscaping: The following comments are offered regarding the landscaping plan, dated May 1, 2006: -170- . The site is required to have a minimum of 18,661 square feet of canopy cover. The landscape plan includes a total of 15,875 square feet (10,597 of trees and 5,278 of shrubs)
