DOLAN General Manager-Chief Engineer DATE Apri 1 13, 1982 SUBJECT AUTHORIZE $58,400 FOR DESIGN OF STORM DAMAGE REPAIRS TO THE COLLECTION SYSTEM TYPE OF ACTION AUTHORIZE FUNDS SUBMITTED BY Jarred Miyamoto-Mills INITIATING DEPT./DIV. Engineering Division BACKGROUND: Winter storms during 1981 and 1982 have damaged collection system facilities at 13 locations. The extent of the damage is described in the attached listing and the locations are shown on the attached map. The Knox Drive slide occurred during 1981 and the remainder during 1982. In each case continued system operation has been provided by CSO. However, long term repairs are required in order to continue service through the next wet weather season. An estimate of the level of effort required for design of repairs to each of the storm damage sites was made on the basis of information currently available. Details of the estimate are attached; the total request for authorization is $58,400 which includes retention of a soils consultant, engineering design by the Engineering Division and support of design by the Survey Section. Funding for the 1982 storm damage repair projects has been requested through the Federal Emergency Management Agency; however, the status of this funding is uncertain. There is potential for additional damage to occur at the currently identified sites or at new locations depending on weather, drainage and soil conditions. The District staff will respond to any occurrence to maintain service and will report such actions as are required to the Board of Directors at the next scheduled Board meeting at which time additional funds may be required. RECOMMENDATION: Authorize $58,400 for design of permanent storm damage repairs to the collection system at 13 locations.

POSITION PAPER VIA: ROGER J. DOLAN General Manager-Chief Engineer DATE A ril 13 1 982 SUBJECT TYPE OF ACTION PUBLIC HEARING TO CONSIDER APPLICATION FOR GARBAGE RATE INCREASE Public Hearing on Rate Application SUBMITTED BY INITIATING DEPT./DIV. WalterN. Funasaki, Finance Officer Accounting Division BACKGROUND: At its Board Meeting on April 1, 1982, the Board of Directors established a Public Hearing on April 15, 1982, to consider a garbage rate increase application submitted by Valley Disposal Service, Inc. Public notices were placed in newspapers of general circulation on two separate days during the week preceding the Public Hearing. RECOMMENDATION: Conduct a Public Hearing on the garbage rate increase application on April 15, 1982, and determine appropriate garbage rate schedules and implementation dates. EVIEWED AND RECOMMENDED FOR BOARD ACTION PM April 13, 1982 MEMORANDUM TO: THE HONORABLE MEMBERS OF THE BOARD OF DIRECTORS VIA: ROGER J. DOLAN, GENERAL MANAGER-CHIEF ENGINEER ~ FROM: Walter N. Funasaki SUBJECT: REVIEW OF APPLICATIONS FOR GARBAGE RATE INCREASES The District staff analysis of the garbage rate increase application submitted by Valley Disposal Servi'ce, Inc. was presented for Board considera- tion and review at the April 1, 1982 Board Meeting. The following queries were made by Board Members which are being responded to in this memorandum: QUERY: What would the garbage franchisees' operating ratios be if no rate increases were granted at the beginning of the fiscal year ended March 31, 1983? RESPONSE: The following summary presents the projected operating ratios for the fiscal year ended March 31, 1983 based on no rate increase being granted: Zone 4 Valley Zone 5 Di a b 10 Zones Zones Zone 2 4 & 5 2, 4 & 5 Lafayette (Combined)(Combined) Projected Revenue $2,247,008 1,317,916 973,208 3,564,924 4,538,132 Projected Operating Expenses 2,341,540 1,375,307 1,001,542 3,716,847 4,718,389 Projected Loss $ (Q4,532) (57,391) (28,334) (151,923) (180,257) Projected Operating Ratio With No Rate Increase 104.2% 104.4% 102.9% 104.3% 104.0% I QUERY: What efficiencies have be~n realized by Valley Disposal Service as a result of the consolidation of the pick-up of garden trimmings and garbage? RESPONSE: Consolidated pick-ups of garden trimmings and garbage have been practiced by Diablo Disposal Service since February 1977. Valley Disposal implemented the ~rocedure in April 1981 and Lafayette Garbage Disposal initiated it in February 1982. Formerly, two-men truck cnews picked up garbage and trimmings on separate days. Under the Iconsolidated pick-up system, two and three-men truck crews pic~-up garbage and trimmings on a single day. In the Valley operation, there were formerly 8 two-men crews for residential garbage collection and 3 two-men crews for residential -1- trimmings. As a result of the consolidation, an additional two-men crew route was added, and la third man was added to two routes. Two men became surplus and in late 1981 and early 1982 these positions were eliminated; a truck was made available as a reserve unit for emergency use and maintenance work. In the Lafayette operation, there were formerly 6 two-men crews for residential garbage collection operating five days a week, and 1 two-men crew operating three days a week for trimmings. The trim- mings crew worked for two :days a week in commercial pick-ups. As a result of the consolida~ion in pick-ups, residential routes were expanded by one two-men crew. The number of hours worked by garbage collectors range from five or six hours to eight hours per day, depending on the pace used by individual crews. This has not been significantly impacted by the consolidation in pick-ups. The number of trips to th~ dump site per day is dependent on seasonal factors which affect the ~olume of trimmings. As a result of the consolidation, Valley Disposal Service estimates that trips to the dump site have incr~ased by two per week. 4~ ~--, <-> Wal:ter N.
