Cross Sections The typical street section will be ran in order to cut cross sections at 50 foot intervals. The typical street section will label the location of roadway centerline, pavement thicknesses and types of material. The cross sections will show the impacts to adjustments to the vertical profile in regards to right-of-way and easement impacts, touch -down locations, drainage impacts, utility impacts, etc. Detailed Design for Sanitary Sewer and Watermain The detailed design for the sanitary sewer and watermain will be completed. All invert elevations, pipe sizes and pipe slopes will be labeled for the sanitary sewer. The profiles will be created for both the sanitary sewer and watermain. The pipe sizes, hydrant locations, DIP fittings, and hydrant elevations will be determined. Detailed Design for Stormwater Related Improvements The hydrologic model will be refined. A drainage area map will be created and the size of the drainage basins will be identified. The curve numbers and time of concentration for the contributing areas will be estimated. The ponding areas will be identified and will be modeled, and the 2-YR, 10-YR, and 100-YR elevations will be determined. The storm sewer will be sized by identifying the sub -watershed areas and a storm sewer drainage map will be created. Storm sewer will be sized for the 10-year return frequency. The need for stubbing storm sewer to adjacent property will be analyzed. The inlet spread will be determined and additional catchbasins will be added if necessary. The limits of the construction will be analyzed to determine all areas where runoff will enter and leave the site to ensure that no drainage issues are created. A drainage pattern exhibit will be prepared. Detailed Design for Trail/Sidewalk Facilities The detailed design for trail and sidewalk facilities, if any, will be completed. Construction Details Provide details of all standard features and other required special details to fully communicate the construction requirements. Landscaping Plan The landscaping plan will be prepared, which will inform the Contractor of the method of restoration expected, plantings, trees, etc. Detailed Design for Highway 10 Improvements The detailed design for the improvements within the Highway 10 right-of-way will be prepared. The turn lane lengths, geometry, pavement sections, etc. will all be designed per Mn/DOT standards. Traffic Control Plan Traffic control and staging plans will be prepared. Detour routes/local access will be analyzed. 5
