Mn/DOT Agreement No. 81361 A kick-off ineeting will be held once all data needed to complete the project has been provided and reviewed by each party. The information to be provided includes aS- builts, topographic maps, drainage calculations and plans for the area north of T.H. 36 and other pertinent information as requested. At this meeting, the overall layout and boundaries of the project will be discussed along with a review of possible alternatives to be modeled. Two meetings with State are anticipated. The first meeting will be to discuss the proposed XP-SWMM model layout and overall project goals. At the second meeting the XP-SWMM model results will be reviewed and alternatives for necessary corrective action will be examined prior to the completion of the overall project report. Prepare XP-SWMM Model for Har-Mar Drainage Study Area Expand the existing HydroCAD model completed for the Har-Mar Mall Drainage Study into a XP-SWMM model. The XP-SWMM model will be created using the drainage areas from the existing HydroCAD model, modifed to matCh the feld-verified drainage boundary (available from State). It will also include a review of all available data (as-builts, topography maps and other data), a review of the existing drainage model, feld verifcation of inlet locations and type, and calibration of the completed SWMM model using existing data. Prepare SWMM Model for the Area Between T.H. 36 and County Road C Expand the existing drainage model for the area between T.H. 36 and County Road C into an XP-SWMM model. The XP-SWMM model will be created using the same drainage areas as the existing model. It will also include a review of the data provided (as-builts, topography maps, existing drainage model and drainage boundary maps, and other data), feld verifcation of the inlet locations and type, and calibration of the completed XP-SWMM model. 4. Analyze Design Alternatives Analyze culvert-crossing alternatives that will be presented during City and State project meetings. The analysis will be completed using the XP-SWMM model created for the existing drainage areas with the necessary model parameters changed to reflect the various options. Construction Cost Estimates Complete quantity estimates along with a detailed cost estimate for the construction of the design alternatives for the culvert crossing of T.H. 36. Final Report Compile and provide a summary of all XP-SWMM model output including the existing drainage system and the effect of the proposed alternatives, preparation of exhibits and recommendations for improvements to the drainage system linking the Har-Mar pond with Zimmerman Lake.
