<br />1 SE Main Street, #204, Minneapolis, MN 55414 888.232.5512 www.SpackConsulting.com <br />Technical Memorandum <br />To: Kent Roessler, Paxmar <br />From: Mike Spack, P.E., P.T.O.E. <br />Date: January 8, 2018 <br />Re: Miske Meadows Traffic Comparison <br /> <br />The purpose of this memorandum is to compare the amount of traffic generated by the proposed <br />residential development on the Miske Property to the amount of traffic anticipated to be generated by <br />the site’s development in the 2004 River Park Traffic Study. The site is located south of County Road 13 <br />(Twin Lakes Road) and west of County Road 40 (Davis Street) in Elk River, Minnesota. <br /> <br />Background <br />In 2004, Traffic Data Inc. completed a traffic study of the proposed development area which included 547 <br />Single Family Homes and 174 Townhomes. The current development plan is for the Miske property to be <br />developed with 462 Single Family Homes and 32 Townhomes. Also notable since 2004 is the construction <br />of Twin Lakes Elemntary School on the northern portion of the study site. <br /> <br />Traffic Forecasts <br />The Institute of Transportation Engineers’ Trip Generation Manual is a dataset of traffic generated by <br />different land use types and is the industry standard for forecasting the amount of traffic generated by <br />developments. A trip generation analysis was done of the proposed development per the Trip Generation <br />Manual, 10th Edition. The results are in Table 1 shown next to the trip generation forecasts from the 2004 <br />River Park Traffic Study. <br /> <br />Table 1 - Trip Generation Comparison <br /> Description (Source) <br />Daily Trips <br />Weekday AM <br />Peak Hour <br />Weekday PM <br />Peak Hour <br />Entering Exiting Entering Exiting Entering Exiting <br />2004 River Park Traffic Study 3,130 3,130 116 370 411 232 <br /> <br />2018 <br />Update <br /> Elementary School – 820 Students (ITE- 520) <br /> Single Family Homes – 462 Units (ITE-210) <br /> Multi-Family Housing – 32 Units (ITE-220) <br />Total <br />775 <br />2,180 <br />117 <br />3,072 <br />775 <br />2,180 <br />117 <br />3,072 <br />297 <br />85 <br />3 <br />385 <br />253 <br />256 <br />11 <br />520 <br />67 <br />288 <br />11 <br />366 <br />72 <br />169 <br />7 <br />248 <br />Change in Traffic with 2018 Proposal -58 -58 269 150 -45 16 <br /> <br />Conclusion <br />The reduction in proposed single and multi-family homes on the Miske property from the 2004 study has <br />decreased the estimated amount of site traffic both daily and in the PM peak hour. However, the AM peak <br />hour traffic shows an increase in traffic, which is largely due to the addition of the elementary school.
