Setbacks are as follows: Lake 75 ' Side 10' Rear(street) 30' Hardcover limitations: 0-75' from lake—no hardcover 75-250'—25% of that area 250-500' -30% of that area Maximum structural coverage: 15% of entire lot(included in structural coverage is any building or structure over six feet high) Maximum building height: two stories plus a defined half-story and 30 feet of defined height. Septic System: Installed in 2009 and designed for seasonal use only for three bedrooms. Layout of system attached. Expansion Issues: Setback—Viewed from the lake the right hand side wall of the cabin has a 1.4 foot setback from the adjacent property line at the back corner and 2.4 feet at the front corner. The steps encroach onto the neighboring property. (Based on an August, 2009 survey by Sathre-Bergquist, Inc. of the adjacent property, partial copy attached.) Any expansion upward or to the front or rear would have to meet the 10 foot setback. Floodplain—The survey includes some spot elevations that suggest the area where the cabin is floodplain (at or below 931.5). A horizontal addition would have to have a minimum first floor elevation of 932.5 with no mechanical equipment or ductwork located below this elevation. If value of the addition exceeded 50 percent of the value of the cabin as it exists now, the whole cabin would have to be elevated. Unless it is possible to enlarge the floodplain elsewhere on the property to compensate for filling to elevate the cabin, it would have to be placed on post footings or a floodable crawlspace. Rebuild as it-While state statutes allow replacement in kind of dwellings that do not comply with local zoning requirements, the replacement must comply with the FEMA floodplain regulations. Every effort has been made to insure the accuracy of the information contained herein;however, if any information is not consistent with provisions of the City Code, the Code provisions will prevail.
