Background <br />FILE#05-3110 <br />11 May 2005 <br />Page 3 of 5 <br />The applicants' property is located on Tanager Lake. Tanager Lake is classified by the <br />Department of Natural Resources (DNR) as a Recreational Development Lake, within the <br />Shoreland Management section of Orono's Zoning Code it is stipulated that a <br />Recreational Development Lake requires a 100' structure setback for properties with on- <br />site septic systems. The applicants would like to construct a window dormer for added <br />space and safety in an existing 2nd story bathroom. As the entire home is located within <br />the 100' structure setback, any building envelope expansion requires a lake setback <br />variance. Additionally, the applicants would like to construct a small garage addition to <br />the north of their attached garage. <br />LOT ANALYSIS WORSHEET <br />Lot Area/Width: <br />RR-lB Lot Area Lot Width <br />Required 87,120 s.f.
