Since then <br /> we have had several communications to discuss your options and the <br /> steps required for the repair of your septic system. A report <br /> submitted to us on December 21, 1992 from S-P Testing, Inc. <br /> indicates that a pressurized mound system may be possible but <br /> several limitations exist. Some mottling is present at a depth of <br /> 12" in a portion of the proposed mound site, which is the minimum <br /> acceptable by City and State of Minnesota codes . A wetland is also <br /> present approximately 60' from the proposed site which, based on <br /> City topographic information, has potential for flooding. This <br /> site does, however, meet the Minnesota Pollution Control Agency <br /> Standards Chapter 7080 . The City would require a variance to the <br /> 75' setback required for wetlands, but staff would likely approve <br /> such a variance if the potential flooding can be addressed and no <br /> other significant limitations exist . <br /> At the time the soil testing information was submitted to the City, <br /> you indicated your interest in requesting the City Council to grant <br /> a Comprehensive Plan Amendment for hookup to the City sewer. In <br /> order to present this request to the City Council, staff would ask <br /> that we arrange an additional meeting with you and your site <br /> evaluator to address the limitations of this proposed drainfield <br /> site as well as investigate any other possible drainfield sites on <br /> your property. More complete soil boring and percolation test <br /> information will be required for the installation of an on-site <br /> system or for use as evidence that a hookup to City sewer is <br /> necessary. <br /> In order to assure timely repair of the failing septic system, the <br /> following time table has been established: <br /> TELEPHONE-473-7357•FAX-473-0510 <br />
