Implications of Maintenance Activities to be Conducted by the <br /> City (for multiple-parcel low-density residential developments and a small <br /> portion of the high-density residential, commercial, and industrial <br /> developments) <br /> K <br /> According to the recommended strategy, the City would conduct all maintenance <br /> activities for low-density residential developments, with the exception of vegetation <br /> maintenance and debris/litter removal, which would be conducted by the private entity. <br /> The fact that the private entity would conduct some of the maintenance activities would <br /> reduce the FTE (full time staff equivalent) needed for maintenance. However, one <br /> additional FTE would be needed for inspection/enforcement to ensure maintenance <br /> activities for low-density residential developments are conducted. The resulting estimate <br /> of cost and labor hour implications is provided in Table 4. <br /> Table 4 <br /> Maintenance Implications at Build-Out for Low Density Residential Development <br /> Low Density Residential <br /> Estimated#of Developments: 840 <br /> Estimated Annual Maintenance Cost: $1.2 million(includes $0.1 million for <br /> inspections/enforcement) <br /> Estimated Annual FTE: 6 (5 for maintenance and 1 for inspections <br /> /enforcement) <br /> Note: The annual maintenance cost to maintain stormwater ponds was reduced from the amount shown in <br /> Table 3 ($3,500)to account for the smaller sized ponds(approximately 0.3 acre-foot)that would be <br /> required for a 5-acre development. <br /> As described above, the numbers in Table 4 are based on the assumption that 1/3 of new <br /> developments would construct ponds, 1/3 would construct swales, and 1/3 would <br /> construct structural facilities. It should be noted that a different mix of the allowable <br /> BMPs may be implemented on low-density residential developments. The City will be <br /> encouraging and emphasizing the use of site-planning controls. Implementation of site- <br /> planning controls could significantly reduce the above estimated cost and labor hour <br /> implications to the City. In addition, some of the developments will be greater than 5 <br /> acres which would result in a smaller number of BMPs. Therefore, the estimated <br /> maintenance implications that are provided in Table 4 should only be used as planning <br /> level estimates to identify potential required maintenance activities, staffing, and <br /> equipment. <br /> It should also be noted that the numbers in Table 4 are based on full build-out. However, <br /> they do not include any projections with respect to facilities that would be constructed in <br /> association with re-development, key waterways, or stormwater capital projects. <br /> Although maintenance activities for water quality facilities on HDR/Com./Indus. <br /> developments would be the responsibility of the private entity, an assumption was made <br /> that a portion of these facilities (15%) would not be adequately maintained. Therefore, <br /> the City would need additional FTE to conduct this maintenance. The additional FTE <br /> required for maintenance are provided in Table 5 below. <br /> I:\945042ne\task0400\memo8\Stormwater Policy Team Meeting.doc 6 <br />
