The City will review applications for standard <br />on -site sewage treatment system designs provided each site meets <br />the following minimum conditions necessary for proper functioning <br />of such systems: <br />a. Lot Size: The lot shall have an adequate area for all existing, <br />and expected improvements in addition to areas of soil suitable <br />for the installation of two on -site sewage treatment systems, <br />known as the "primary drainfield site" to be used initially, <br />and .the "alternate drainfield site" to be used should the primary <br />site ever fail. In all cases, at least 10,000 square feet of <br />suitable soil and slope shall be identified within each lot <br />as dedicated for drainfield use. <br />b. Soils: The following sc"I classification series shall in <br />most cases be considered suitable for installation of standard <br />systems: <br />Anoka - AnB, AnC Hayden - HbB, HcC2 <br />Braham - B+B, Bi-C Lester - LrB, LrC, LsC2 <br />Burnsville - BuB, BuC, BxB, BxC <br />C. Percolation Rate: The percolation rate must be faster than <br />60 minutes per inch and slower than 0.5 minutes per inch. <br />d. Depth to Groundwater or Seasonally Saturated Horizons: For <br />proper functioning of this system the minimum de,.th to groundwater <br />or seasonally saturated conditiont.shall be more than 5r- <br />e. Flooding Hazard: There must be no hazard of flooding in the <br />area where these systems are installed. <br />f. Slope: The land slope in the area proposed for the soil absorption <br />field shall not be greater than 12%. <br />I I <br />!I <br />�I <br />9' <br />-10 <br />
