MINUTES OF THE ORONO PLANNING COMMISSION MEETING HELD ON APRIL 17, 1995 (#8 - #2011 Tim & Lori Line - Continued) The Applicants were present and were represented by their architect, Blake Bichanich of Keith Waters Sc Associates Mabusth reported that the commission originally dealt ssith this undeveloped property in 1993 graming hardcover and height variances Excesses in hardcover were to be olTset with the installation of a drainfield The current proposal also involves a hardcover variance and height variance for an obsers ation tower located in the middle of the structure A drainfield to the west will treat nint^ff from 20+^% of total hardcover requests Mabusth also m>ted a gain of area due to a redefinition of the shoreline at the 929 4 elevation on the new survey Staff reviewed the surve>or's field notes and finally accepted the surveyor’s findings lacking any specific criteria for defining shorelines adjacent to wetlands either within ihe City's or DNR regulations Mabusth clarified how the height of the building is determined The legal height of the highest part of the roof, the observation tower, is 35’ The structure is 4T at the peak height from the lakeview The tower is planned in order to gain more light with the interior of the structure Bichanich commented to the members that the tower, although needing a height variance, is limited in its afi'ect on the area The applicant could add volume to the home, which would create a more massive look, without requiring any height variance. It was noted that 20% of the hardcover would be treated through the drainfield system. Nolan asked the applicant how this is controlled Bkhanich advised there would be four 1000 gallon runoff tanks, which would be equipped to take in 2" of runoff in a one-hour span Beyond that time and amount, the excess runoff w ould leech into the surrounding ground A pump with valves would pump out any sediment. A check valve would be installed to eliminate any backup of the system. If the system is overburdened, this would result in an overflow spilling out onto the lawn. Schroeder questioned if the house plan was worth the cost to install the treatment area. The architect responded that without the treatment, the result would have been a one-third reduction in the size of the home During public comments, Mrs Erickson of Forest Lake Landing asked the location of the dock Erickson was concerned with the wetland areas. Tim Line reported approval of the plans from two neighbors, and the letters of approval were read into the record by Peterson.
