John Slack, Perkins + Will May 2, 2016 Land O’Lakes Expansion TS Update Page 21 Parking To evaluate the future parking need at the expanded headquarters, various data points were compiled. Parking lot inventories were completed in October 2015 during the following time periods: • Weekday – 9:30 a.m. to 10:30 a.m. • Weekday – 1:30 p.m. to 2:30 p.m. Additionally, aerial imagery from weekdays dating back to the year 2013 were reviewed. Finally, a parking generation estimate was completed using the ITE Parking Generation Manual, Fourth Edition based on the average peak parking rate for the most comparable land use for which parking data was available. A summary of compiled parking data is shown in Table 8. Table 8 Parking Generation Summary Parking Parameter Size Parking Demand Parking Capacity Existing Conditions Maximum Observed Parking (Site Visit) 991 Employees 832 Vehicles 931 Spaces (Existing Capacity) Maximum Observed Parking (Aerials) 761 Vehicles Maximum Observed Parking Rate 0.840 Veh./Employee Office Building (701) 823 Vehicles Year 2018 Conditions Estimated Peak Parking Demand Based on Maximum Observed Parking Rate 2,109 Employees 1,772 Vehicles 1,860 Spaces (Parking Demand Including Five Percent Surplus) Office Building (701) 1,751 Vehicles Capacity Conditions Estimated Peak Parking Demand Based on Maximum Observed Parking Rate 2,519 Employees 2,116 Vehicles 2,220 Spaces (Parking Demand Including Five Percent Surplus) Office Building (701) 2,091 Vehicles Based on the existing maximum observed parking rate, a peak parking demand of 2,116 vehicles is estimated for employee capacity conditions at the expanded headquarters. It is recommended that a minimum five percent surplus of parking spaces be provided to reduce unnecessary circulation of motorists looking for parking and the perception of inadequate parking. Therefore, a minimum of 2,220 parking spaces is recommended at the expanded Land O’Lakes headquarters for employee capacity conditions. It should be noted that the currently proposed parking capacity for the expanded Land O’Lakes headquarters is 1,685 spaces. A parking deficit of approximately 535 spaces is estimated based on the recommended capacity of 2,220 spaces. However, it should be noted that the Requirements for Parking, Loading and Circulation (1325.06) in the Arden Hills Zoning Code require one space of off-street parking for every 250 square feet of gross floor area for business and professional offices. At this rate, the proposed 418,800 square foot facility requires only 1,676 off-street parking spaces.
