From the submitted documents it appears that none of the structures will be in <br />violation of floodplain ordinances. It appears that parts of the different athletic fields would be in the floodway. <br />A detailed hydrologic model should be submitted to ensure that any fill and grading does not cause a stage <br />increase during the 100 year event (1% event) per your ordinance sec 30-1912 (d). <br /> <br />In many situations the Ordinary High Water Elevation (OHW) is found to be the same elevation as the floodway. <br />The applicant should contact the Area Hydrologist with a detailed survey of the site to ensure that no additional <br />permits are required to work below the OHW. <br />Sincerely, <br /> <br />James Bedell <br />Area Hydrologist <br />|1035 S Benton Dr.| Sauk Rapids, MN 53379 | (320) 223-7850 | james.bedell@state.mn.us | <br /> <br />EC: Dan Petrik; MN DNR Land Use Specialist <br /> Tim Crocker; MN DNR North District Manager <br /> Nancy Riddle; Sherburne County Zoning Administrator <br /> Ceil Strauss; MN DNR Floodplain Hydrologist <br /> <br />
