Chapter 153 Water Resource Management Adopted 6/28/2022 Page 12 of 34 (A)Location map. The map shall show the site location with property lines in relation to surrounding roads, other geographic features, buildings and other structures. (B)Topography. (1)Topography showing two-foot contours for the site, invert elevations of existing storm sewer, and/or spot elevations of the conveyance system from drainage discharge points to the nearest receiving waterbody and for a minimum of 100 feet beyond the site boundary. (2)Topography showing ten-foot contours for subwatersheds upstream and downstream of the project site. Where topography in the region is characteristically flat or hydrologic flow path is undetermined, two-foot contours may be required. (C)Vegetation map. In areas where there has been a natural resource or similar inventory, the map shall show the location of trees and vegetation on-site, with identification of those trees and vegetation intended to be retained. (D)Landscape Plan. The plan shall show proposed conditions and shall contain the following: (3)Pervious area identified in square feet or acres; (4)Seed mix(es) or other vegetation type(s) proposed; (5)Note that vegetation must be established to 90% coverage with 100% coverage in areas of concentrated flow. (E)Erosion and Sediment Control Plan. The plan shall have both existing and final proposed conditions drawn to scale, shall be consistent with the manual Protecting Water Quality in Urban Areas (Minnesota Pollution Control Agency, 2000) as revised, and shall include the following: (1)Proposed area of grading or other land-disturbing activities and delineation of the limits of disturbance including areas of grubbing, clearing, tree removal, grading, excavation, fill and other disturbance; (2)Quantity of soil or earth material to be removed, placed, stored or otherwise moved on site; (3)Locations and descriptions of proposed runoff control, erosion prevention, sediment control and temporary and permanent soil stabilization measures; (4)A sequence of land alteration activity and corresponding implementation of erosion control practices, monitoring, maintenance and removal of erosion and sediment control measures; and permanent site stabilization measures. Prior to commencing activity (following all necessary approvals), the responsible party shall provide the SWCD with a construction schedule which will include approximate dates for the following: (a)Completion of installation of perimeter erosion and sediment controls; (b)Completion of required seeding and mulching activities; (c)Completion of land-disturbing activities and putting into place measures for final soil stabilization and re-vegetation; (d)When the site will be permanently stabilized and re-vegetated;
