DATE SUBJECT ADOPT A RESOLUTION ESTABLISHING THE 1992-1993 APPROPRIATIONS LIMIT IN ACCORDANCE WITH ARTICLE XIII B OF THE CALIFORNIA CONSTITUTION A TYPE OF ACTION ADOPT APPROPRIATIONS LIMIT SUBMITTED BY INITIATING DEPT.lDIV Walter N. Funasaki, Finance Officer Administrative/Finance & Accounting ISSUE: The Central Contra Costa Sanitary District is required to establish its appropriations limit in accordance with Article XIII B of the California Constitution. BACKGROUND: On August 20, 1992, the Board of Directors authorized posting a public notice of the availability of documentation in support of the District's appropriations limit. As statutorily required, the public notice was made at least 15 days prior to the September 16, 1992 Board Meeting at which the adoption of the appropriations limit is recommended. Formerly, the appropriations limit was increased annually by a factor comprised of the change in population combined with either the change in California per capita personal income or the Consumer Price Index, whichever is lower. As amended by Proposition 111 in 1990, the Consumer Price Index was replaced by the percentage change in the local assessment roll from the preceding year due to local nonresidential construction. The Board is to select between the per capita personal income, or the change in the local assessment roll due to local nonresidential construction, by a recorded vote. The 1990-1991 appropriations limit was to be computed based upon the 1986-1987 appropriations limit adjusted from that year forward by the new growth factors. However, the change in the local assessment roll, which is intended to be obtainable from the County Assessor, was not available for use for the 1990-1991 fiscal year and, therefore, the per capita personal income factor was used. The County Assessor was able to provide the nonresidential construction index beginning with the appropriations limit for the 1991-1992 fiscal year. The County Assessor has determined the nonresidential construction index for 1992-1993 to be 5.1 percent. The California per capita personal income change for use in computing the 1992-1993 appropriations limit is a negative .64 percent. Therefore, the change in the local assessment roll of 5.1 percent is used in the calculation of the 1992-1993 appropriations limit. The computation of the 1992-1993 appropriations limit by application of the California per capita personal income and population percentage change factors to the 1986-1987 appropriations limit adjusted from that year forward to 1990-1991, and the nonresidential construction index for 1991-1992 and 1992-1993, was provided at the August 20, 1992 Board Meeting. The Sewer Construction Fund (Capital Fund) appropriations limit so computed is $14,559,079 for the 1992- 1 993 fiscal year. INITIATI,NG DEPT.lDIV.

DATE September 11, 1992 SUBJECT AUTHORIZE THE PURCHASE OF AN EXPLOSION-PROOF REFRIGERATOR AND AUTHORIZE THE EXPENDITURE OF $2,200 FROM THE 1992-93 EQUIPMENT BUDGET CONTINGENCY TYPE OF ACTION AUTHORIZE EQUIPMENT PURCHASE SUBMITTED BY Bhupinder S. Dhaliwal laborator Superintendent INITIATING DEPT./DIV. Plant Operations Department ISSUE: Board authorization is needed to purchase equipment items from the Equipment Budget Contingency when the cost exceeds $2,000. BACKGROUND: The laboratory uses an explosion-proof sample refrigerator to store laboratory samples preserved in different types of solvents. An explosion-proof refrigerator is needed to meet laboratory safety requirements. The existing sample refrigerator has failed. This refrigerator is over 15 years old and appears to have passed its useful lifespan. According to a commercial refrigerator repair company, the existing refrigerator cannot economically be repaired. They recommend replacement with a new unit at a cost of $2,200. RECOMMENDATION: Authorize the purchase of an explosion-proof sample refrigerator from the 1 992-93 Equipment Budget Contingency.

BIDS AND AWARDS a. DATE August 31, 1992 SUBJECT AUTHORIZE AWARD OF CONSTRUCTION CONTRACT FOR THE FILTER PLANT REHABILITATION PROJECT, DP 20095, TO AUBURN CONSTRUCTORS, INC; AUTHORIZE GENERAL MANAGER -CHIEF ENGINEER TO EXECUTE AGREEMENT WITH CH2M HILL TYPE OF ACTION AUTHORIZE AWARD AUTHOR~EAGREEMENT SUBMITTED BY Andrew J. Antkowiak, Assistant Engineer INITIATING DEPT./DIV. Engineering Department/Infrastructure Division ISSUE: On September 2, 1992, sealed proposals were received and opened for the construction of the Filter Plant Rehabilitation Project, District Project 20095. The Board of Directors must authorize award of the contract or reject bids within 50 days of the bid opening. Authorization by the Board is required to execute consulting engineering agreements for amounts greater than $50,000. BACKGROUND: During a reclaimed water demonstration project in 1988 it was found that various improvements to the filter plant are necessary in order to meet the Department of Health Services' requirements and to ensure reliable operation. The necessary improvements were identified in a predesign report completed by CH2M Hill in 1989, and included in the Filter Plant Rehabilitation Project. These improvements include new piping with control valves and meters, a new alum polymer tank, a protective coating system for the filter walls and troughs, a modified backwash system, and addition of filter media pre purchased by the District. The upgrading of the instrumentation and control system includes the installation of new control panels, modifications of existing panels, wiring, programmable logic controllers and an operator interface unit. The project site is shown in Attachment 1. The plans and specifications for this project were prepared by CH2M Hill and the project was advertised on August 3 and 10, 1992. The adjusted engineer's pre-bid construction cost estimate was $1,040,000. This estimate was reduced by District staff from $1,300,000 to reflect the favorable bidding climate. Eight sealed bids ranging from $ 812,300 to $ 1,012,000 were received and publicly opened on September 2, 1992. A summary of the bids received is shown in Attachment 2. The Engineering Department conducted a technical and commercial review of the bids and concluded that the lowest responsible bidder is AUBURN CONSTRUCTORS, Inc., with a bid of $ 812,300. The additional funds required to complete this project are $1,311,000, as shown in Attachment 3. The total estimated project cost is $1,936,350. The project funding summary is shown in Attachment 4. The project is included in the 1992-93 Capital Improvement Budget on pages TP-72 through TP-73.

The construction engineering services and filter plant control systems software programming will be provided by CH2M Hill. The construction engineering services will include evaluation of contractors submittals, preparation of design clarifications, system start-up assistance and preparation of record drawings. The software programming will include development of display screens for the Filter Plant control system and programming of the logic controllers. A cost reimbursement agreement has been negotiated with CH2M Hill with a cost ceiling of $57,000 for the construction services, and $70,300 for the software programming. This project has been evaluated by staff and has been determined to be exempt from the California Environmental Quality Act (CEOA) under District CEOA Guidelines Section 18.2 since it involves the maintenance of an existing public facility with negligible or no expansion of capacity. Board of Directors' approval of this project will constitute agreement with this determination unless otherwise indicated. RECOMMENDATION: 1. Authorize award of contract for the construction of the Filter Plant Rehabilitation Project, District Project No. 20095, in the amount of $ 812,300 to AUBURN CONSTRUCTORS, Inc. as the lowest responsible bidder. 2. Authorize the General Manager- Chief Engineer to execute a cost-reimbursement agreement with a cost ceiling of $127,300 with CH2M Hill for construction engineering services and software programming. 13028-7/91 .-.--... ............--.., ......---r''--.. ..-....-......--.---.-.-..---------".---...- --....--- ..-.-..---...----...-----.- ------------.-------.
