TO: Jeanne Mabusth, Zoning Administrator Thomas Jacobs, Building Inspector Alan Olson, Village Planner FROM: Michael Gaffron, On -Site Systems Manager DATE: October 21, 1980 SUBJECT: Synopsis of History and Recommendations on Septic System Jerry Hansen House, 3051 Farview Lane Since the location and type of septic system for this house is a point of contention at the present time, I will review what has happened on it to date: Farview Subdivision approved; Lot 7, Block 1, contains two existing wetlands and drainage easements surrounding it as per attached copy of plat. 9-4-79 Percolation test site evaluation report by Mark Gronberg indicates location of perc tests and borings and proposed a shallow trench drainfield system in natural soil due to high water table. 11-13-79 A3ditional testing to west of 9-4-79, apparently due to relocation of house, indicated shallow trench drainfield would work. Report indicated original alternate site would become primary site, new testing would be alternate. 11-12-79 Applic2 Guhmitted plans for home with site plan and survey indicat a tennis court spanning drainage easement in southeast corner 12-3-79 Septic proposal approved as attached sheet, noting location of primary and alternate siteE and stating that tennis court could not encroach on drainage easement. Also stated that rear yard area was to be preserved for primary and future drainfield; also must maintain 75' separation from edge of actual wetland. 8-80 Nitz contacted me to discuss locating a tennis court on the lot and how to work it in with a septic system. Although the City had previously and again indicated to Nitz or his agents that there was little room on the lot for a tennis court and primary and alternate d- infield, and/or filling to the extent Hansen wanted. We discussed some possible options as to septic systems for the lot including a sand bed for primary and future mounds to southwest of house. At this point no major disturbance of original soil had occurred in the rear yard drainfield areas. Nothing was resolved. Nitz said he would decide what he would do and notify the City.
