TASK DESCRIPTION <br />3.0 DESIGN <br />Assumptions: <br />- Realignment of CSAH 33 (up toll feet north) is requested from 350 feet west of <br />Auburn Street thru Smith Street and sections along the new corridor prior to the <br />roundabout to accommodate the future trail along south side of CSAH 33. <br />- Right of way linework needs to be updated for CSAH 33 centerline shift. <br />- No intersection lighting required at side streets. <br />- No trail surfacing or subbase (aggregate or bituminous) is planned. <br />- An urban section consisting of curb and gutter along south edge of shoulder from <br />approximately 350 feet west of Auburn Street east through the intersection of <br />Quincy Street is planned for accommodating the future trail. Additional sections of <br />urban (curb and gutter) are planned from approximately 100 feet of the planned <br />cattle pass east to the roundabout. <br />- Urban boulevard width will be a typical 5 feet measured from face of curb to the <br />grading PI for the section of CSAH 33 from the TH 169 exit ramp east thru Quincy <br />Street. <br />- Trail is not carried anyfurtherthan a graphical representation (2D) <br />- Additional stormwater treatment locations, including pond(s) will be reviewed to <br />accommodate both the current project and future trail construction. Storm water <br />treatment locations will be located and designed to provide flexibility for the current <br />and future expansion abilities. <br />- Adjust two previously proposed stormwater treatment ditches to accommodate <br />road shift to the north. Proposed design does NOT account for treatment of future <br />trail impervious. <br />- No pedestrian ramps or ADA design are included forthe futuretrail. <br />- Engineer's Estimate and Statement of Estimated Quantities (SEQ) will be expanded <br />to provide separate quantity columns for County & City cost participation for CSAH <br />33 and separate column for County participation on CSAH 13. <br />- No specific driveway design required for future trail considerations. SRF will cut <br />sections at driveways for new CSAH 33 alignment and review driveway slopes for <br />general conformity for future trail. Minor grade adjustments will be reviewed (if <br />necessary) to facilitate the future trail as deemed reasonable with this project. <br />- No modifications to the roundabout are included with this additional scope. <br />- QC reviews are included in each task as necessary. <br />- No bench will be graded into the back slope alongthe rural section east of Quincy <br />Street forthe future trail. <br />Work Tasks and Person -Hour Estimates <br />PROF.
