The actual HydroCAD models will need to be provided for review, <br />not just project summaries. <br /> <br />The drainage permit application, including the information below, should be submitted online to: <br />https://dotapp7.dot.state.mn.us/OLPA/ <br /> <br />The following information must be submitted with the drainage permit application: <br /> <br />1) A grading plan showing existing and proposed contours. <br />2) Drainage area maps for the proposed project showing existing and proposed drainage <br />areas. Any off-site areas that drain to the project area should also be included in the drainage area <br />maps. The direction of flow for each drainage area must be indicated by arrows. <br />3) Drainage computations for pre and post construction conditions during the 2, 10, 50 and 100 <br />year rain events. <br />4) Time of concentration calculations. <br />4) An electronic copy of any computer modeling used for the drainage computations. <br />5) See also the attached Drainage Permits Checklist for more information. <br />Once a drainage permit application is submitted, a thorough review will be completed and <br />additional information may be requested. <br /> <br />Please direct questions concerning drainage issues to Jason Swenson (651-234-7539) or <br />Jason.Swenson@state.mn.us of MnDOT’s Water Resources section. <br /> <br />Permits: <br />In addition to the Drainage permit mentioned above, a Miscellaneous work permit is required for <br />the water connection with the MN 95 ROW. Additionally, any other use of, or work within or <br />affecting, MnDOT right of way will require a permit. <br /> <br />Permits can be applied for at this site: https://olpa.dot.state.mn.us/OLPA/. Please upload a copy of <br />this letter when applying for any permits. <br /> <br />Please direct questions regarding permit requirements to Buck Craig of MnDOT’s Metro Permits <br />Section at 651-775-0405 or Buck.Craig@state.mn.us. <br /> <br />Review Submittal Options <br />MnDOT’s goal is to complete reviews within 30 calendar days.
