Ms. Katie Larsen <br />June 6, 2018 <br />Page 8 <br /> <br /> <br /> S:\Community Development\Projects\Planning Cases\Nature's Refuge\Staff Reports\20180611 CC (RZ & PUD PP)\20180611 v2 (revised 20180608)\a2 2018060 <br />4. Upgrading Main Street (CSAH 14) to a 4-lane roadway has been identified by both <br />Anoka County and the City for some time in the future but has not been programed. <br />Therefore, should the analysis show that existing conditions do not require <br />improvements at Street A and Main Street (CSAH 14), documentation should be <br />provided of when in the future with the existing lane configurations the improvements <br />would be needed. See revised memo from Spack. <br />5. Assuming that the intersection of Main Street (CSAH 14) and Lake Drive (CSAH 23) <br />will be addressed in the future, no further analysis over what is included in the current <br />Traffic Study would be required. Comment noted. <br />6. Street A and Street C shall be 32 feet wide from face of curb to face of curb. The plans <br />currently show back of curb. As discussed, 32’ back to back is acceptable. <br />7. The cul-du-sac widths can be reduced to 28 feet wide from face of curb to face of curb. <br />Cul-de-sacs have been updated to 28’ back to back. As discussed, 28’ back to <br />back is acceptable. <br />Cul-de-sacs shall be 30’ back to back. <br />8. The ACD 10-22-32 crossing shall be wide enough to accommodate the road, a 5 foot <br />buffer and an 8.5 foot wide trail with 4:1 side slope tapers. <br />Ditch crossing updated. Street C extended to the northern property line. <br />9. The future trail extension along 10-22-32 should be relocated to the same crossing as <br />Street C. Thus there would only be one ditch crossing. <br />Ditch crossing updated. <br />10. There is a future trail planned along the north side of Main Street. The plans shall <br />include the grading for this trail. This will likely also require hydrant relocation. <br />Grading for a future trail has been incorporated. Hydrants will be relocated at the <br />time of trail construction. <br />11. The applicant shall remove the trees identified in the Landscaping Plan from the sight <br />line triangle of Street A and Main Street (CSAH) 14. Revised per city comments. <br />12. A bituminous trail is recommended through this site. As noted in the wetland section of <br />this report the proposed location, along Lots 1-6 Block 3, is within the 25 foot buffer and <br />should be relocated. The proposed trail location is allowed by RCWD rules and <br />will therefore not be relocated. According to RCWD Rule F 6(e)(7)(iii) – Buffer may <br />enclose a linear surface for non-motorized travel no more than 10 feet in width. The <br />linear surface must be at least 25 feet from the wetland edge. The area of the linear <br />surface will not be eligible for replacement credit. For projects proposing non- <br />motorized travel no more than 10 feet in width, the linear surface may be reduced to less <br />than 25 feet from the wetland edge based on compelling need and a TEP <br />recommendation to the District in support that the wetland protection afforded is <br />reasonable given the circumstances. Per Kjolhaug Environmental Services. <br />13. The proposed sidewalks were reviewed. Pedestrian curb ramps will be required, and <br />reviewed with the final construction plans. Comment noted. <br />14. Street C temporary cul du sac should have continual curb and gutter and temporary <br />paved eyebrows. The storm sewer will need to be adjusted. <br />Temporary cul-de-sac and storm sewer has been updated. <br />15. The Revised Traffic Study provided a summary of the Level of Service for each <br />intersection movement for CSAH 14 and Street A. It concludes that in the build <br />2030 and build 2030+ conditions the southbound left turn would operate at a LOS <br />F. Are the recommended improvements discussed on page 9 of the Study included
