Flood Hazard - There must be no floodini; hazard. <br />d). Slope - The land slope in the area being considered for in <br />stallation of the system must not be greater than 12"8. <br />e).Position on the landscape - 'ITie system shall be installed on level <br />areas, on top of rises on convex slopes, on sides of rises on <br />plane. The systems shall not be installed in depressions, swales, <br />or drainageways. <br />Details on the construction procedures for these systems may be ob <br />tained from the District Office in IVavzata. <br />5. Marsh - Mli: <br />This is a collection of organic soils. There is generally water at <br />the surface for the entire year except during exceptionally dry periods. <br />On-site soil absorption systems may not be installed in these wet­ <br />land areas. <br />V. CRITICAL EROSION .AREAS <br />The area of proposed subdivision lies adjacent to a wetland area on the <br />North Arm of Lake Minnetonka. Provision should be made in any develop­ <br />ment plan for the control of erosion and the resultant sedimentation. <br />The slope of the land in this area is not e.xcessive but erosion can be <br />a problem on these soils if they are left exposed for long periods. For <br />this reason some guidelines for the establisliment of temix)rary and per­ <br />manent vegetation are provided for areas which will be exposed during <br />construction. <br />h <br />» i <br />$ <br />tOMBt
