Andrew Witter, Sherburne County April 25, 2017 <br /> CSAH 1 and MN Highway 10 Traffic Review [2] <br /> 5) When southbound left-turn queues extended through the North and South Shell Driveways, <br /> motorists generally did not block the intersection,leaving a gap for westbound left-turning vehicles <br /> to turn onto CSAH 1. This improved the side-street approach delay. <br /> a) However,when no westbound left-turning vehicles were present, southbound queues would <br /> generally block the intersection. Although gaps were present,westbound left-turning vehicles <br /> at the North and South Shell Driveways were observed completing aggressive maneuvers. <br /> 6) Approximately two (2) to three (3) pedestrians were observed crossing CSAH 1 during both the <br /> a.m. and p.m. peak hours. <br /> 7) Although not the focus of this study, other approach queueing was observed at the CSAH 1/ <br /> MN Highway 10 intersection: <br /> a) Northbound queues extended approximately 400 feet during the a.m. and p.m. peak hours. <br /> b) Eastbound left-turn queues extend beyond the storage 25 percent of the p.m. peak hour. <br /> c) Westbound thru queues extend past Oxford Avenue (approximately 350 feet east of CSAH 1) <br /> 30 percent of the p.m. peak hour. <br /> Northwest Quadrant Redevelopment <br /> 8) The area in the northwest quadrant of the CSAH 1/MN Highway 10 intersection is planned to <br /> be redeveloped. According to the Sherburne County comprehensive plan, the area is currently <br /> zoned urban residential, but is proposed to change to highway business commercial. <br /> 9) The entire redevelopment area is approximately 125,000 square feet. To estimate a reasonable <br /> building size for the area, similar highway business locations in the area were reviewed. Based <br /> on this review, a building size of approximately 25,000 square feet was assumed. <br /> 10) To provide a conservative estimate, trips were estimated using the ITE "shopping center" land <br /> use code. <br /> 11) Existing homes were removed from the proposed trip generation estimate. <br /> 12) The proposed development is expected to generate approximately 21 a.m. peak hour trips, 89 <br /> p.m. peak hour trips, and 1,029 daily trips. <br /> 13) Alternative 2 may have less developable square footage due to the placement of the proposed <br /> roadway, but for the purpose of this study 25,000 square feet of leasable area was assumed for <br /> all alternatives to remain consistent and conservative. <br />
