Ms. Katie Larsen <br />June 6, 2018 <br />Page 7 <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 /> Transportation <br /> <br />The Nature’s Refuge subdivision is proposed on the north side of Main Street (CSAH 14) <br />between Lake Drive (CSAH 23) and 4th Avenue. Access will be from a new street <br />connection (Street A) to Main Street (CSAH 14). The development will be set for future <br />extensions to the west, north, and to Lino Lakes Elementary. To improve access control on <br />Main Street, the City is working with School to remove their west access and connect to <br />Nature’s Refuge. <br /> <br />A Traffic Study evaluating the Nature’s Refuge development was submitted by Spack <br />Consulting. The development includes 60 single family homes that are anticipated to <br />generate approximately 565 new trips per day, 45 new trips in the a.m. peak hour and 60 <br />trips in the p.m. peak hour. <br /> <br />Comments: <br /> <br />1. The Study needs to provide an analysis of the existing LOS with and without the <br />proposed development as outlined in the Section 1001.013(2)(c). <br />See revised memo from Spack. The revised Traffic Study addressed a portion of <br />this comment. The Study should also consider what the impacts are for an interim <br />analysis a year after the development is completed as well as the no-build <br />conditions without development for comparison. <br /> <br />The May 17, 2018 revised Traffic Study addressed a portion of this comment: on page 5 <br />for the planning level screening analysis by including the 2015 no-build analysis. <br />However, an interim year was not considered to address when improvements with a two <br />lane facility may be need prior to the 4 lane facility being constructed. In addition, <br />the Intersection Analysis on page 7 and 8 did not include the 2015 no-build or interim <br />year analysis. <br /> <br />Following discussions with the developers engineer an updated revised Traffic Study <br />dated June 4, 2018 was prepared to address the remaining portion of the comment. The <br />Study now includes the analysis of the interim 2021 conditions with the proposed <br />development with existing geometric conditions. <br /> <br />2. Projected traffic from any future phases of development (extension of Street B, Street C, <br />and Lino Lakes Elementary) that would use Street A to access Main Street (CSAH 14) <br />should be included in the analysis. See revised memo from Spack. <br />3. It is anticipated that Street A would require designated turn lanes at Main Street. <br />The Study should evaluate the intersection of the new Site Access Street (Street A) and <br />Main Street (CSAH 14) for both safety and operations. It is anticipated that Anoka <br />County Highway Department will require right and left turn lanes on CSAH 14 (Main <br />Street). The turn lane construction shall be add throughout the preliminary plat <br />documents. <br />Turn lanes denoted throughout the plans. Detailed turn lane construction plans <br />will be part of the final construction plans.
