Zoning File #1531 May 16, 1990 Page 2 of 4 Review of Previous Subdivision Application Involving Creation of 2 Riparian Lots - In June of 1976, the Orono Council approved the 2 lot riparian subdivision. The applicant failed to pay required park and consultant review fees. The original approval expired within 6 months of the approval date. Applicant reapplied with the same proposal and was denied based on the need foi lot width variance as property did not meet the required 200* of width at the 75 setback line. The 2 lot riparian subdivision application was denied by the Orono Council in April of 1978. Review of Current Application - Please review Exhibits F, G and H. The current proposal proposes 1 riparian lot that meets the required lakeshore setback of 100' at the 75' setback line. Lot 1 also meets the required lot width to the rear of the front yard setback line of 30'. Lot 2 has a rear line that ends at a point. Although Definition 40 of the zoning code would suggest that the rear lot line be determined as shown on the staff's sketch (Exhibit G), a lakeshore setback of 75' is applicable. Lot 2 is obliged to meet the 75' setback from the 929.4' elevation although not defined as a lakeshore lot. In review of Cook's report (Exhibit E) and his sketch (Exhibit F), the area of the drainage ditch cannot be Included within the dry buildable 1/2 acre building envelope of proposed Lot 2. Applicant's surveyor has been asked to confirm the dry buildable envelope exclusive of the hatch area defined in the Engineer's sketch. Staff has asked the Engineer to stake the drainage ditch along the east lot line. Upon a site inspection, it will be difficult for members to determine actual lot corners. Note the encroachment upon the property of the gravel drive serving adjacent neighbor. Applicant's surveyor has already confirmed that there would be no problem meeting the 1/2 acre dry contiguous requirement to the west of the defined drainage ditch. Staff notes that Lot I's existing hardcover, the newly adjusted 75-250' setback area at 15,500 s.f., now shows excesses of hardcover totaling 360 s.f. Applicant must advise what portions of existing hardcover ate to be removed. Cook has also asked that all portions of the lakeshore property involved within the flood plain (areas below 931.5 ) be designated and the City take a Conservation & Flowage Easement over the flood plain area. This action would not be consistent with previous reviews in determining dry buildable areas for lakeshore lots. The 931.5' elevation has been used to designate wetlands adjacent to the lakeshore where wetlands and lake interact. Please review this property's lakeshore. There are no wetlands nor are there designated wetlands shown on the City ^ official mapping. Dry buildable area of each lakeshore lot has always been determined from the 929.4* elevation. Staff would recommend that the drainage and utility easements ^ defined as always within plats along the perimeters of properties and along the shared lot lines at a 5' width. Drainage easement along the south and east portion of the property is to be designated at 5 on either side of the center line of the drainageway.
