#02-2772 John and Donna Crotteau I40S Sixth Avenue North Page 3 of4 4. A detached building 750 s.f. or less is only required to meet a 10 ’ side setback. The detached building must have a minimum of 10 ’ separation between it and the principal building. Sliding the garage back to be 10 ’ from the principal building also moves the garage back out of the 30’ top of bluff setback, thus eliminating the need for any variances for the garage. DNR Review and Commcats When projects have a potential impact on natural features, such as a bluff, the City of Orono will typically request comments from the DNR. The Planning Commission did not have the benefit of the recommendation provided by the DNR for their review. A copy of the DNR comments are attached. The DNR objects to the portion of the project that further impacts the bluff and suggests the project be scaled back. In a phone conversation with Peter Leete, of the DNR, he stated there was no objection to the portion of the project that was located away from the lakeside. In response to the DNR comments the plan was further reviewed to determine all potential negative impacts to the bluff and existing grades on the property. The total ground elevation from the house to the end of the addition is approximately 2-3’. The property begins a more dramatic drop where the exterior wall of the lakeside addition is proposed to end. Access around the house would become difficult without creating a flat area in front of the addition. The land alteration to create a walking path around the front of the house would require additional land alteration and fill that is not permitted on a bluff. Analysis The original construction of the house was in 1984, prior to the adoption of the Shoreland Ordinance in 1992. The Shoreland Ordinance also regulates areas defined as a “bluff ’. Nearly the entire 10.4 acre property is defined as either a wetland or is protected bluff area, including all the land in which the existing house is located. The house is located well above the 930’ wetland elevation. The actual house elevation is approximately 987 ’. The City Engineer has reviewed the plans and has commented the proposed additions to the building do not present any concerns from an engineering perspective. Mr. Kellogg did state silt fence shall be installed lakeside of the home prior to any construction or site grading. The MCWD will also have the same requirements and require permits of their own. A large wetland is located at the base of the bluff area, between the lakeshore and the house. The wetland basin covers approximately S acres in area. The dr.'inage from the house enters the wetland prior to entering the lake.
