Zoning File #1909 March 17, 1994 Page 3 T - Floor Plans U - Building Section V - Elevation Review of Request Lot 1, Block 1, Green Trees on Tanager Lake was platted in September of 1980 and was approved at 1.69 acres. The property is not sewered, requiring an on-site septic system. All other lots within the Green Trees plat have been developed. The last remaining lot is the most severely limited of the lots within the subdivision with steep topography and a roadway that surrounds the majority of the building envelope. The recent Shoreland Regulations not only created new protective regulations for bluff areas but also reclassified Tanager Lake as a Recreational Development Lake requiring 100’ setbacks for all structure. Much of the shoreland of tlw property is occupied by a wetland. The builder has advised staff that applicants propose no alterations of the shoreland area and wish to maintain it in its pristine condition. Applicants will seek to remove dead trees and trim and prune existing trees. Any trees proposed for removal will be evaluated by the Building staff to determine the type and number of trees to be removed. Staff will seek replanting schedule and determine if level of tree removal would be classified as clear cutting which is not allowed under the ordinances, refer to Section 10.56, Subd. 16 (1-2) noted above. Applicants have managed to locate a house, septic system and generous driveway layout within the building envelope all meeting the 25% hardcover allowance. Applicants have been only recently notified of the presence of bluff areas on the propeny requiring more restrictive setback from the top of lakeside bank. There is little room within the building envelope to relocate proposed house. Mike Gaffron has prepared various exhibits to depict the bluff impact zone as defined within the current ordinance, proposed land alterations within the bluff area and the impact of fill on the downside/lakeside of the bluff, review Exhibits P, Q and R. Because of the limited building envelope, any other attempt to relocate home would require a street setback as well as a bluff setback. Any readjustment would have to be to the northwest cul-de-sac area as the septic prevents movement to south and east. The structure would still not meet required 30’ setback from top of bluff. Staff will have a sketch of the building pad and a footprint of the house to assist in determining whether house can be relocated to a more acceptable location. In reviewing the exhibits on the slope determinations, note that a 9’ rise in a 50 ’ segment results in a 18% slope. As the house is currently proposed, it will encroach within both the bluff impact zone and 30’ required setback. Filling is proposed not only around the house pad but to the lakeside of house, refer to Exhibit P. No doubt our current code is restrictive and as we interpret and implement the code, we find
