4 <br />Grading Plan and Stormwater Management <br /> <br />Stormwater management for the tree farm proposes to have the driveway and building <br />areas as the only impervious surfaces for the site. The remaining areas, including the <br />parking area (Grassprotecta), are proposed to remain as pervious surfaces. Drainage for <br />the lot will continue to flow from east to west across the site to Cedar Lake. The gravel <br />driveway and agricultural building create approximately 7,000sf impervious surface. The <br />entire site is 39.87 acre. Stormwater ponds are not required if the impervious surface is <br />less than 10,000sf. <br /> <br />Public Utilities <br /> <br />Public utilities are not required for the tree farm operations. <br /> <br />Landscape Plan <br /> <br />Landscaping standards will not apply to this agricultural use. <br /> <br />The proposed plan does include ample coniferous trees to screen the site from the property <br />to the south and to screen the driveway. <br /> <br />Sod and Ground Cover Standards <br /> <br />The Turf Establishment Plan calls for Mn DOT 25-131, a low maintenance, drought <br />tolerant turf grass over the parking lot and any other disturbed areas. The seed will be <br />installed under a GRASSPROTECTA reinforcement mesh to minimize rutting and wear <br />to the grass. <br /> <br />Category 2 wood fiber blanket is specified in the Grading, Drainage, and Erosion Control <br />Plan. This must be updated to reflect the current Mn DOT category number with a note <br />that the City requires natural net erosion blanket. <br /> <br />Signage <br /> <br />One 4ft x 3ft (12sf) ground sign is proposed south of the driveway near CSAH 32/CR J <br />(Ash Street). The sign is proposed within the private driveway easement. Technically, <br />the sign would be considered an off-premise sign and not allowed; however, staff would <br />support the sign as a condition of the Conditional Use Permit. The easement owners need <br />to formally amend the existing easement or draft and record and new document to allow <br />for the sign. The easement shall clearly detail who is responsible for maintenance and <br />removal of the sign. <br /> <br />A sign permit application would be required using the site plan to show the exact location <br />of the sign. Per City Code Chapter 1010, a ground sign for non-residential uses in a R, <br />Rural zoning district may only be 8ft in height. The sign shall not be located in the Ash <br />Street right-of-way or within the vision triangle.
