Flow elevation in the 2 and 10-year storm events may also be required. (6)Cross sectional flow area at 100-year flow elevation for existing and proposed conditions. For sites with low-lying land, or structures, pipes, or other constructed features at elevations that are at risk of being affected by changes in the 2- and 10-year hydraulic profile, the cross-sectional flow area at the 2- and 10-year flow elevations will also be required. (7)Changes to water surface elevations between no-bridge, existing, and proposed conditions. This information should be provided for a range of river stations and should encompass, at a minimum, the point upstream and downstream of the structure at which the project results in no change in water surface elevation. (8)For projects on public waters, provide a copy of the permit package submitted to the DNR. Additional information as relevant and necessary to evaluate an application may be required.

STANDARDS § 153.55 EROSION AND SEDIMENT CONTROL DESIGN AND OPERATIONAL STANDARDS. (A)Carver County adopts and incorporates by reference the erosion and sediment control design and operational standards as set forth in Minnesota Permit R100001 (the General Permit Authorization to Discharge Storm Water Associated With Construction Activity Under The National Pollutant Discharge Elimination System), as amended from time to time. (B)Land altering activity shall not result in the detrimental deposition of sediment or construction materials into the waters of the state or onto neighboring property. Erosion and sediment control facilities must be installed prior to commencing any construction activity. (C)Erosion and sediment control measures must be designed and maintained to prevent the detrimental deposition of sediment or construction materials into the waters of the state or onto neighboring property. There are a variety of publications available that describe BMP's that can be used to meet these standards. Examples of BMP's can be found in:
