Trip generation rates are highest for commercial developments, such as shopping <br />centers, and lowest for industrial developments. Refer to the Supporting Documentation section <br />on how total Citywide nonresidential trips are calculated. <br /> <br />As indicated in the table, the non-salary operating cost per capita is $9.91. This is calculated by <br />multiplying the non-salary operating cost, $429,745, times the percentage of police calls <br />associated with residential land uses, 79.2 percent. This result, $340,358, is then divided by the <br />current number of residents in the City, 34.334, resulting in a non-salary operating cost of $9.91. <br /> <br />The non-salary operating cost per nonresidential trip is $0.59. This is calculated by multiplying <br />the non-salary operating cost. $429,745, times the percentage of police calls associated with <br />nonresidential land uses, 20.8 percent. This result, $89,387, is then divided by the current <br />number of nonresidential average daily vehicle trips in the City, 170,457, resulting in a non- <br />salary operating cost of $0.53 per nonresidential trip. <br /> <br />The table also indicates that an additional 1,276 residents will trigger the need for a new patrol <br />officer. An increase in 24,057 nonresidential trips will also generate a new patrol officer. These <br /> <br />Page 20 <br /> <br />Tischler & Associates. Inc. <br />
