Page 50 20. Transportation a) Describe traffic-related aspects of project construction and operation. Include: 1) existing and proposed additional parking spaces, 2) estimated total average daily traffic generated, 3) estimated maximum peak hour traffic generated and time of occurrence, 4) indicate source of trip generation rates used in the estimates, and 5) availability of transit and/or other alternative transportation modes. Trip Generation A traffic impact study was completed for the Oakwater Ridge development (dated April 2nd, 2025) and included as Appendix N. The study included the following intersections:  Highway 10 & 165th Avenue NW/Specht’s Lane  Highway 10 & 171st Avenue NW “The AM peak traffic hour was found to occur from 6:45-7:45 AM and the PM peak traffic hour was found to occur from 3:45-4:45 PM” based on existing turning movement counts taken on Wednesday, November 13th, 2024 (Appendix N). “The volume of vehicle trips generated by the Proposed Project has been estimated for the weekday AM and PM peak hours and on a daily basis using the data and methodology described in the Institute of Transportation Engineers’ Trip Generation Manual, 11th Edition” (Appendix N). “The proposed 536 single-family homes are estimated to generate 375 trips (94 entering and 281 exiting) during the morning traffic peak hour, 503 trips (317 entering and 186 exiting) during the evening traffic peak hour and 5,054 daily trips”. When the future Twin Lakes Interchange is constructed the commercial potential of the site is likely to develop. “Full Build with Commercial is estimated to generate 516 trips (180 entering and 336 exiting) during the morning traffic peak hour, 764 trips (441 entering and 323 exiting) during the evening traffic peak hour and 7,928 daily trips. These trips are presented to use in planning for the future interchange.” “Growth in background traffic was considered with roadway specific annual growth rates estimated by reviewing historical MnDOT traffic counts.” (Appendix N). Parking Section 30-903 of Chapter 30 of the City code outlines the minimum parking requirements. Single-family dwellings require one enclosed parking space plus two off-street spaces. The development will adhere to the minimum parking requirements set forth by the City. The future tenant of the commercial lot is not known at this time. The future developer of the commercial lot will be subject to Section 30-903 of Chapter 30 of the City code. Convenience stores require at least one parking space per two hundred square feet of floor area, but not less than six spaces. Retail stores require one parking space for each two hundred square feet of floor area. The layout/footprint of the commercial parcel will be finalized in subsequent review/permitting processes. Transit The NorthStar Commuter Line offers service between Big Lake and downtown Minneapolis. The Elk River Station is located near the site at the intersection of Twin Lakes Road and 171 st Lane (5).
