STAFF ORIGINATOR: MEETING DATE: AGENDA ITEM 5.A. Paul Bengtson July 9, 2008 TOPIC: Variance to the Shoreland Ordinance — Ordinary High Water Setback 7625 Peltier Lake Drive To allow the replacement of a private sewage treatment system BACKGROUND Mark Fairbanks has requested approval of a Variance from the Ordinary High Water Level (150 feet) to allow a sewage treatment system that would be 50 feet from the Ordinary High Water Level of Peltier Lake. The proposed sewage treatment system would meet all other setback requirements on the lot. The property is located on the eastern shore of Peltier Lake at the intersection of Peltier Lake Drive and 77th Street. The existing sewage treatment system has failed and must be replaced. The applicant has submitted information showing that the best location for a new drain field is directly above the existing drain field on the site. This will be accomplished by installing a box mound system. This is due to soil conditions, the location of the home's well, and the rather small size of the lot. ANALYSIS Comprehensive Plan, Land Use and Zoning: as well as guided land uses for the area. The table below identifies the existing land use and zoning Location Existing Land Use Guided Land Use Existing Zoning Site Residential Low Density Unsewered Residential Rural North Residential Low Density Sewered Residential Rural South Residential Low Density Unsewered Residential Rural East Residential Low Density Unsewered Residential Rural West Peltier Lake Peltier Lake Peltier Lake Setbacks: The Zoning Ordinance has no specific setback requirements for onsite sewage treatment systems. The ordinance does require almost all improvements to be setback a minimum of five feet from property lines. The Shoreland Ordinance requires the 150 foot setback from the Ordinary High Water Level of Peltier Lake. To come close to meeting this requirement the property owner would need to put the sewage treatment system in the front yard of the property, however the property's well is already located in the front yard. Sewage Treatment systems are required by state law to be setback 10 feet (tanks) and 20 feet (drain fields) from dwellings, 10 feet from property lines and 50 feet from wells. These requirements further reduce the area a system can be placed on the site. •
