PROPOSED IMPROVEMENTS <br /> Proposed improvement objectives consist of reducing the abrupt elevation drop at the <br /> intersection of Coleman Drive and Pequot Boulevard and redirecting surface drainage to mitigate <br /> direct discharge into wetlands and Sibley Lake.To accomplish this,two alternative solutions <br /> were examined and are described below. <br /> Alternative 1 <br /> This alternative includes placing enough fill at the toe of the steep hill,near the intersection of <br /> Coleman Drive and Pequot Boulevard,so that the hill becomes a more gradual slope.Without <br /> field survey or measurements yet,we anticipate this alternative would require minimal clearing, <br /> marginal changes to the road alignment and geometry,and some rehabilitation to the subgrade in <br /> the immediate area. <br /> Coleman Drive is proposed to be 18 feet wide,bituminous paved with concrete curb and gutter. <br /> To address environmental concerns with present drainage, surface drainage would be re-routed <br /> via curb and gutter to the lowest section of the road,then piped west to a permanent stormwater <br /> management area near the south side of the existing cul-de-sac.Existing driveway approaches in <br /> the middle segment of Coleman Drive will require minor adjustment in elevation to match the <br /> new road surface elevation which is anticipated to be 5 to 6 inches higher than the present <br /> roadway surface.The 5 to 6 inches increase in roadway height is due to additional class 5 and <br /> bituminous surface to be placed.A 1 to 2-foot bituminous kick out apron is typically extended by <br /> the paver at driveway entrances. <br /> Alternative 2 <br /> This alternative includes adjusting the profile of Pequot Boulevard so that the elevation of the <br /> intersection of Pequot Boulevard and Coleman Drive is lower, in turn heling to decrease the <br /> steepness of the slope on Coleman Drive. Without field survey or measurements yet,we <br /> anticipate this alternative would require some clearing, some changes to the road alignment and <br /> geometry,and rehabilitation to the subgrade in the immediate area. <br /> CITY OF PEQUOT LAKES Page 8 FEASIBILITY REPORT <br /> WIDSETH PROJECT NO.2021-12098 COLEMAN DRIVE <br />
