Zoning File #1232 <br />December 16, 1987 <br />Page 2 of 2 <br />Staff will ask for the standard drainage and utility easement along <br />lot lines. The Engineer's report (Exhibit F) seeks drainage calculations <br />for storm sewer and pond area shown in engineering plans for road (Exhibit <br />E). The drainageway to ponding area has been directed along the shar'.-d lot <br />lines of Lots 2 and 3. Ponding area in Lot 3 should be designated on the <br />preliminary plat and described in angles and bearings. The area of the <br />ponding area must be excluded from the dry buildable calculations of the <br />lots. Storm sewer drainage to the wetlands to the southeast of the subject <br />property and then via drainage tile under Luce Line and then via overland <br />drainage to Stubbs Bay is described on Exhibit I. The City must have <br />the drainage calculations to determine impact on down stream properties. <br />In addition. Cook has asked for a storm sewer profile, detail of pond <br />outlet control structure, and design of drainage ditch to south to ensure a <br />minimum of erosion problems given the severe sloping topography. Cook asks <br />that the road plans be amended as follows: <br />1.Bank at west side adjacent to Stubbs Bay Road be graded out. <br />2.Ditch bottom set 3' below existing center line at property line. <br />3.Back slope graded to a 3:1 slope. <br />4.Bituminous flumes provided to drain the curb section at Stubbs Bay <br />Road. <br />Staff has enclosed a plat of the surrounding neighborhood (Exhibit H), <br />designating approximate location of houses, boundaries of individual <br />properties and surrounding road locations. At a minimum, staff would <br />recommend that an extended access to the east lot line be provided for a <br />future connector/through road to Loaf Street. Note 30+ undeveloped acres <br />within RLS #843 at the east quadrant. There is no more than a 1 to 1^ acre <br />wetland within the entire property v»ith a potential development density of <br />15+ lots. Staff cannot recommend approval of the preliminary plat of the <br />Betz Builders subdivision until the following is resolved: <br />A.Exact area of each lot exclusive of ponding area and road right- <br />of-way extension. <br />B.Storm sewer detail as noted above. Applicant to file a formal <br />application with M.C.W.D. to review drainage and grading plan. <br />Applicant may have to relocate location of private road at least along <br />the west side of property to make up for dry lands now used for ponding <br />area that will also serve land owner to north. Lot 5, when developed in the <br />future .
