CR 53 for the length of the site and that the City consider further trail construction beyond the limits of this development for logical tie-ins to the existing city street and trail network for users. Depending on the future section of CSAH 14, the trail may need to be located in a separate easement outside of the County R/W. • The City should also give consideration to including sound walls in the development agreement since there is a possibility that CSAH 14 will be reconstructed as a divided 4 lane road at some point in the future, necessitating a noise analysis and likely noise walls if federally funded. • The proposed connection from the ring -road to the extension of Century Trail is likely too close to CSAH 14 and will need to be shifted farther to south, as NB traffic queues at CSAH 14 may back-up through the intersection. The traffic analysis will likely verify this. • As noted above, a roundabout is currently planned for the intersection of CSAH 14 and CR 53. We have placed a few roundabout concept footprints at the intersection and determined that the proposed R/W dedication is not sufficient. From our preliminary review, we recommend the NW corner of the site should include a triangular R/W chamfer with 80' legs from the current proposed ROW intersection. If the traffic study proposes a roundabout at the new, western street access, then we would like a similar dedication on that corner, as well. As depicted on the concept plan, 60' of R/W along CR 53 and 75' along CSAH 14 should be adequate for future County highway reconstruction. • Utility relocation along CSAH 14 and CR 53 should be anticipated, and the County will require that utility coordination and relocation plans be included in the approved development plans for this project. County staff should be included in the utility relocation meetings for this project. • Internal site grading for the development is not to commence until the required ACHD Engineering Plan Review approvals are received and applicable permits can be issued. We appreciate the opportunity to review this development at a concept plan level. Please reach out to Logan Keehr or myself if you have any questions or would like to meet and discuss. We look forward to working with you on this project. Thanks, Brandon T.
