14 <br />3. Elevations, sections, profiles, and details as needed to describe all natural <br />and artificial features of the project. <br />4. Proposed grade contours at one-foot intervals shown as solid lines. <br />5. An estimate of the total volume (cubic yards) of materials proposed to be <br />imported to or exported from the site. <br />6. Provisions for groundwater management (dewatering), including <br />subsurface drains, disposals, ponding and flood controls. <br />7. Spot elevations at drainage break points and directional arrows indicating <br />site swale and lot drainage. <br />8. Proposed lot lines, lot and block numbers, building style, building pad <br />location and elevations at the lowest floor and garage slab, if applicable, for each lot. <br />9. Locations, sizes, grades, rim and invert elevations of all proposed <br />stormwater facilities, including ponds, proposed to serve the subject property. <br />10. The location of all oversize, non-typical easements including conservation <br />easements, if applicable. <br />11. Show the boundary of the 100-year flood elevations of all waterbodies. <br />12. Locations of all stormwater management practices, infiltration areas, and <br />areas not to be disturbed during construction. <br />13. Normal water level, high water level, and emergency overflow elevations <br />for the site and all associated ponding systems. <br />14. Location of areas where construction will be phased to minimize duration <br />of exposed soil areas. Include map and calculations as necessary of areas of grubbing, <br />clearing, tree removal, grading, excavation, fill, and other disturbance; areas of soil or <br />earth material storage; quantities of soil or earth material to be removed, placed, stored, <br />or otherwise moved on site, and delineated limits of disturbance. <br />15. Location and type of all temporary and permanent erosion prevention, <br />sediment control, stormwater runoff, and soil stabilization BMPs, along with procedures <br />to be used to establish additional temporary BMPs as necessary for the site conditions <br />during construction. Standard plates and/or specifications for the BMP's used on the <br />project must be included in the final plans and specifications for the project. Location <br />and design of temporary sediment basins where ten acres or more (five acres or more <br />for special or impaired waters) are disturbed and drained to a single point. When site <br />restrictions do not allow for a temporary sediment basin or less than the required <br />acreage is being developed, temporary sediment basins where appropriate are <br />encouraged, but not required in areas with steep slopes or highly erodible soils or to <br />take equivalent measures such as smaller basins, check dams, and vegetated buffer <br />strips. <br />16. Methods to be used for final stabilization of all exposed soil areas. <br />17. Documentation that the project applicant has applied for the NPDES <br />permit from the Minnesota Pollution Control Agency (MPCA), when applicable.
