5. Hydrologic /Hydraulic Design Exhibits: <br />One copy of the following shall be submitted. The calculations shall be prepared by a <br />registered professional engineer. <br />A. All hydrologic and hydraulic computations completed to design the proposed <br />stormwater management facilities shall be submitted. Model summaries must be <br />submitted. The summaries shall include a map that corresponds to the drainage areas <br />in the model and all other information used to develop the model. <br />B. A table (or tables) must be submitted showing the following: <br />i. A listing of all points where runoff leaves the site and the existing and proposed <br />stormwater runoff rates and volumes. <br />ii. A listing of the normal water levels under existing and proposed conditions and <br />the water levels produced from the storm and runoff events listed above for all <br />on -site wetlands, ponds, depressions, lakes, streams, and creeks. <br />C. A completed LRRWMO stormwater volume reduction checklist (attached). <br />6. Erosion Control and Sedimentation Prevention Exhibits: <br />A. One 11 -inch by 17 -inch copy and two full -sized plans if larger than 11 inch by <br />17 inch, which show how waterborne sediment will be prevented from leaving the site <br />during and after construction to prevent sedimentation of downstream water bodies. <br />The plans shall include a construction sequencing schedule. <br />B. A copy of the Stormwater Pollution Prevention Plan (SWPPP), prepared by a qualified <br />individual, which conforms to the MPCA's NPDES Construction Stormwater Permit <br />requirements. The NPDES permit requirements cover both temporary and permanent <br />erosion prevention and sediment control measures, and apply to all construction <br />projects that disturb one or more acres of land. The SWPPP must conform to the <br />special requirements for "Special Waters" (the Rum River classified as a Wild and <br />Scenic River), when applicable. The SWPPP shall also show how erosion will be <br />prevented during construction on individual building sites. Any applicable local <br />standards shall be incorporated into the plan. <br />7. Construction plans for all proposed stormwater management facilities. Construction <br />specifications must be provided upon request. <br />8. A maintenance agreement, as described in the LRRWMO policies. <br />9. Four copies of the Wetland Delineation Report, which also must include a summary of the <br />MnRAM evaluation (Minnesota Routine Assessment Method for Evaluating Wetland <br />Functions, Version 3.0 or updated versions). <br />10. Five copies of Part 1 of the Combined Wetland Permit Application (CWPA) for all projects <br />proposing to alter wetlands, which may not require wetland replacement (see Rule 4). <br />P: \Mpls123 MN\02123020471workFiles \Permit Checklist \RcqurdSubmittalsExhibits.docx 2 <br />
