Below are our preliminary comments and thoughts on this site. <br />Please note that when ready, the preliminary plat will still be required to go through the standard <br />formal review process at the County. <br />The County has some concerns with the proposed access points onto CSAH 14 and CSAH 53. Due to <br />the magnitude of the development being proposed, a traffic impact analysis will need to be <br />completed for the development area for Anoka County review and approval. It will need to take into <br />account the directional distribution of the trips to be generated, access spacing, intersection sight <br />distance, intersection operations, safety, intersection control alternatives, recommended geometric <br />improvements, right-of-way needs and impacts, intersection queuing, levels of service, impacts of <br />delays, etc. on the county highways and intersections that will be impacted by this development. The <br />traffic impact analysis should also ensure that the proposed access scheme will be compatible with <br />any potential future development projects north of CSAH 14. <br />The traffic impact study should define a functional intersection control type for the new street <br />access points onto the county highway system, whether they are roundabout, right-in/right-out, <br />three-quarter, or signalized intersection with full turn lanes. (Please note, the County has an <br />unfunded project identified in our 5 Year HIP for the construction of a single lane roundabout at the <br />intersection of CSAH 14 and CR 53, targeted for 2024. We had concerns regarding safety and <br />operations of this intersection, even without the added traffic from this proposed development). <br />Also note that per standard, the costs to implement the recommendations are typically borne by the <br />developer. <br />Some specific concerns and feedback we have are: <br />• The proposed full access onto CR 53 appears to be too close to the existing access for <br />Robinson Dr. It is our recommendation that one of these accesses would need to be a RI/RO. <br />As proposed, the two full access locations do not meet County spacing guidelines. Whether <br />the full access is at Robinson Dr or the newly proposed access is up to the City. Construction <br />of a NB right turn lane and SB left turn lane would be required at the full access intersection <br />on CR 53. <br />9 The County advises that construction of a trail should be considered along both CSAH 14 and <br />
