Kelly Acres _Preliminary Plat Review February 28, 2006 Revised April 5, 2006 2of4 Existing Structures: Please submit a revised site plan indicating the location of all existing structures on the site and how access will be obtained to these homes. Landscaping and Tree Preservation Plan: A landscaping and tree preservation plan, dated March 13, 2006, has been submitted. The site is a remnant of a tree farm and a majority of the existing trees are Red Pines. Within the area of development, approximately 50% of existing trees will remain, mostly in the backyards of the proposed lots. Al1 trees outside the limits of the proposed street and lots will remain. Prior to any construction activity, tree save fencing shall be installed at the dripline of individual trees or groupings. Each lot is required to have a minimum of two (2) trees installed in the front yard, near the property line. Comer lots should have one tree installed along both streets. It does not appear that any existing trees will be preserved in the front yard of the proposed lots and therefore, credit toward required plantings is not warranted. Deciduous trees shall be at least one (I) inch caliper and coniferous trees shall be at least five (5) feet in height at the time of installation. All proposed species are appropriate for this site. A revised landscaping plan wiI1 be verified at Final Plat. Wetlands: It appears that there is a small wetland located on the Kelly Acres site. This should be verified by a wetland delineator and delineated on the site plan. Any wetland impact must be avoided, if possible, and must be approved by the Lower Rum Pdver Water Management Organization (LRRWMO) In addition to delineating the wetland, a buffer around the wetland will need to be maintained. The buffer width is dependent upon the management classification of the wetland, wkich has not been determined. City Code states that it is the applicant's responsibility to supply detailed information to the City so that this determination can be made. It does appear that existing iree cover will satisfy the buffer requirements, but monumentafion will need to be installed on Lots 3- 5 Block 3 denoting the limits of the buffer. At the time that the final plat is recorded, it will be necessary to record a notice of the wetland buffer requirement and prohibited activities against the title of these lots with the Anoka County Recorder. Drainage and Grading: A revised drainage plan has been submitted. A building summary has been submitted showing lot, block, lowest opening and floor elevations, garage opening, 100 year flood elevation pond wetland, centerline elevation; front yard slope (%), rear yard slope (%) and a list of the lots require grading certificates. Staff needs to verify that the 100 year flood elevations shown on the plan represent the conditions for back to back 100 year flood events since this development is a landlocked basin. The city must also verify that the calculations do not anticipate infiltration which is not allowed in the determination of the flood event. -135-
