He introduced <br />Mr. Jim Olson of Bonestroo, the engineering <br />firm retained by the City of Orono for review <br />of this plat. <br />COLPEPPER LAND COMPANY <br />(NESLUND) <br />40 ORONO ORCHARD ROAD <br />SUBDIVISION (PRELIMINARY) <br />REPORT BY ENGINEER <br />JIM OLSON OF BONESTROO <br />(#306) <br />Mr. Olson gave an oral presentation from the <br />written report he had previously submitted to <br />the City. Their findings are based on the <br />map, report and recommendation of the Hennepin <br />County Soil and Water Conservation District <br />and are as follows <br />The proposed plat is approximately 45 acres in <br />size and is located in the northerly part of <br />the City and adjacent to the City of Long Lake. <br />The proposed plat is bounded by the Burlington <br />Northern Railroad, the Luce Line Trail, Orono <br />Orchard Road and the City of Long Lake. The <br />area is heavily wooded except for a small por­ <br />tion on the west and contains several low, <br />marshy areas. <br />It is understood that the zoning requirements <br />include a 2 acre minimum lot size and that sani­ <br />tary sewer service is not contemplated for the <br />proposed plat. Therefore, the ability to provide <br />adequate soil absorption sewer systems for each <br />lot is critical to the development of the plat <br />and a major criteria. <br />The following comments relative to soil types <br />have been taken from the Hennepin County Soil <br />and Water conservation District Report. <br />Peaty Muck (Pa) - The water table in these organic soils is above or <br />near the surface the entire year. These soils are unsuitable for the in­ <br />stallation of any soil absorption system . The peaty muck soils are shown <br />in green on the enclosed map. <br />Glenco (Gc) and Hamel (Ha) - Has the highest water table during the <br />year either at or within 1 foot of the surface. This water table may per­ <br />sist for several months during the year. Installation of any subsurface soil <br />absorption system in this soil obviously would not allow the minimum recommended <br />separation. The mound system is designed for soils v;ith periodic high water <br />tables. However, the water table must not be higher than 2 feet below the sur­ <br />face for the mound system to function effectively. Installation of any soil <br />absorption system on this soil is not recommended. The Glenco and Hamel soils <br />are shown in solid blue on the enclosed soil map. <br />MINUTES OF A <br />Dundas (D' <br />table in this <br />1 and 3 feet. <br />any soil absor^ <br />cross-hatch on <br />Erin (En) <br />in percolation <br />is recommended <br />Mound systems < <br />soils with slo; <br />cross-hatch, <br />are shown as si <br />Based on the H« <br />of the proposec <br />and major areas <br />absorption sysi <br />A plan has beei <br />Normal resident <br />approximately ] <br />187» slopes, vei <br />development to <br />on slopes great <br />IJhen both the £ <br />plat, there api <br />and septic tanl <br />not be approved <br />acceptable indj <br />It must be unde <br />evaluation, but <br />tive to ground <br />formation prioi <br />The external be <br />from Orono via <br />at either end c <br />entrance as ind <br />very steep, woe <br />ing marsh areas <br />proposed lots r <br />difficult. <br />The terrain is <br />However, it is <br />sensitive to th
