SR 89:133 Page 5 Policy Option 1: The most accurate, present-day information is from actual traffic counts, i.e., the Driveway Study. Using this information produces a P.M. trip rate of 1.24 vehicle trips per 1,000 sq. ft. of occupied floor area and 0.38 trips per employee. It assumes an employee density of one per 305 sq. ft., the density of the counted buildings. (The A.M. figure 1.36 trips/i,000 sq. ft. is a derived figure using TSM Survey data for arrival time but with the same employee density and other adjustments consistent with the counted trips.) This selection of buildings includes 2,864,807 sq. ft. and presents an employee density of 305 sq. ft. per employee as compared to the Hacienda Business Park average of one employee per 289 sq. ft. or the total spread sheet average of 311 sq. ft. Policy Option 2: This option presumes that the North Pleasanton building occupancy as it existed before AT&T vacated its various buildings in moving into its new headquarters is more typical of what to expect for trip generation (311 sq. ft. per employee) and uses the Trip information taken from the 1988 TSM Surveys and factors it for arrival-departure, vehicle occupancy and employees not leaving from work. This data base then produces a PM peak hour trip rate of 1.33 trips per 1,000 sq. ft. of occupied floor space and an AMpeak trip rate of 1.51. Policy Option 3: This policy option takes policy option 2 and expands the number of trips to take into consideration that the trip rate will increase if the number of employees increase, therefore, changing the current 311 sq. ft. per employee to 250 sq. ft. per employee. The 250 sq. ft. per employee may more closely approximate employee density at buildout. This data set produces a PM peak trip rate of 1.65 trips per thousand sq. ft. of occupied space and an AM rate of 1.88.
