Arden Hills City Council, December 20, 2013, Pg. 3 <br />Question: More info on road trips, how number of road trips were <br />determined. <br />The trips were determined for the two scenarios using standard trip generation <br />rates per dwelling unit for residential uses and per 1,000 square feet for <br />commercial uses. The standard trip generation rates are published by the <br />Institute of Transportation Engineers based on submitted survey data from <br />practitioners around the country. <br />A four-lane spine road and the reconstructed interchanges at Highway 96 and <br />County Road H currently contemplated by Ramsey County could accommodate <br />either AUAR scenario. Additional ramp improvements may be necessary at <br />County Road H for the maximum scenario. The draft AUAR will provide <br />additional detail regarding transportation impacts and any required mitigation. <br />Table 1 – Site Generated Trips: Minimum AUAR Scenario <br />Land Use VariableNo. of Units Daily Trip Total Daily <br />RateTrips <br />Residential Dwelling 1,500 6 9,000 <br />units <br />Retail 1,000 sq. ft. 500 36 18,000 <br />Non-Retail1,000 sq. ft. 1,700 8 13,600 <br />Commercial <br /> Total: 40,600 <br />Table 2 - Site Generated Trips: Maximum AUAR Scenario <br />Land Use VariableNo. of Units Daily Trip Total Daily <br />RateTrips <br />Residential Dwelling 2,500 6 15,000 <br />units <br />Retail 1,000 sq. ft. 550 36 19,800 <br />Non-Retail1,000 sq. ft. 1,950 8 15,600 <br />Commercial <br /> Total: 50,400 <br />
