The Vegetation Manager and the temporary summer aide have different pay and benefit rates, therefore, the next step of this analysis calculates the varying percentages of each of these positions' time that was spent during calendar year 1989 in the enforcement functions and administration of each management category. By subtracting the total time of all enforcement operation functions from the total annual time devoted to the program, we get the amount of program time spent on administrative duties. When this total amount of administration time is prorated by the calculated percentages of operations time per management category we can calculate the amount of time and resultant program percentage of administration time spent in each category (Table III). With the documentation of position time and administration time per management category, we now have all the information necessary for the actual assignment of costs between the various management categories. At this point the administration costs' for both personal services and materials are calculated for each category (Table IV). Following this, the average operations cost per abatement for each management category is calcu- lated based on an itemization, by category, of the program's operating expenses for calendar year 1989 (Table V). Lastly, the activity costs are calculated for a typical City performed abatement in each management category (Tables VI, VII, & VIII). By multiplying these typical abatement costs by the number of such abatements and subtracting this from the total operations activity costs we calculate the costs involved in program operations not requiring City abatement. Both the calculated administration costs and the nonabatement costs in each category are divided by the number of enforcement functions per category to give us a per function cost for each. All of these costs are then multiplied by the Maintenance Division's indirect overhead rate of 32.8 %. The overhead adjusted administration cost per enforcement function and the overhead adjusted typical abatement cost in each category are added to give us a total cost for City performed abatements in each category. Likewise, the overhead adjusted activity cost for each enforcement or inspection that did not require City abatement is added to the overhead adjusted administration per enforcement function in each category to give us the total cost for each such nonabated enforcement function. The table on the following page (Table X from the main document) summarizes these different costs after the overhead adjusted administration charge per enforcement function has been added. It is these final costs that should be considered as the total Maintenance Division amount to be added to the contractor's charges in the restructuring of a new owner billing schedule. As used herein, administration costs shall refer only to expenses associated with activities or materials used by the Vegetation Manager during the course of the year. They do not include costs associated with the Vegetation Manager's supervision or other organizational administrative or overhead costs. These other organizational costs are included as part of the Maintenance Division's 32.8 % indirect overhead rate.
