l~roo£/ield ~'~ddition Preliminary Plat Review .Jz.dy ;29, 2005 Revised: September 9, 2005 Den.si~: The R-1 Residential r%u]ations Eot the MUSA ~rea ~How a net densi~ oE ~ units per acre. As submitted, the proposed prelimina~ plat has a net densi~ of approximately 1.9 u~ts per acre. Other Lot Requirements: Trott Brook is a designated tributary of the Rum River, and is subject to Scenic River and Shoreland Management requirements. Additional lot standards required under these roles include a 75-foot lot width at the OHW of Trott Brook, a 100-foot setback from the ()llW, controlled vegetative cutting within this 100-foot setback, and a 25% impervious surface limitation fbr lots fronting the brook. The preliminary plat complies with all of these standards, with the exception of the 75-foot lot width requirement as measured at the brook. Staff has had discussions with DNR Staff, who explained that the intent of the Shoreland lot width requirement is to ensure that sufficient lot area is provided. Because of the large lot sizes on the Trott Brook, DNR Sta/~'f ~'eels the intent of the requirement is being met. The preliminary plat submittal indicates that there is one existing building in the northern part of the plat and several in the southern portion of the plat near 166th Avenue. It appears that only the existing home 'on 166th Avenue will remain after platting. All other outbuildings must be removed; City Code does not permit accessory buildings to be located on a parcel separate from the main dwelling. Landscaping/Tree Preservation Plan: The following comments are offered regarding the landscaping plan: Additional screening along Nowthen Blvd should be provided for Lots 1 & 12 Block 1 and Lot 12 Block 2. o Small cranberry (/accinium oxycoccus) must be replaced with a larger species more appropriately sized for screening and that is better suited for this site (small cranberry is more appropriate for bogs/marsh areas). · Planting schedule should include the Latin nomenclature as well as the common name of the plant material. revised landscaping plan is needed that addresses these concerns. The tree preservation plan is acceptable. However, due to the presence of oak trees on and adjacent to the development area; a plan must be submitted outlining the actions that will be taken to protect those trees f?om oak wilt. Any clearing involving oak trees cannot occur between April 15 and July 15 to help protect against oak wilt. Density Transition: Currently, City Code requires density transitioning between the proposed smgle-lhmily urban lots and the surrounding single-family rural lots. City Code establishes several options to achieve the transitioning including landscaping, existing topographical l'camres, or matching densities on common boundaries. It is City Staff's opinion that the existing wetland and conservation easement along the north boundary and the existing wetlands along the southern part of Block 11 of the plat serve as an adequate transition between the urban lots and
