TITLE: APPROVAL OF AMENDMENT OF THE ENCINA WASTEWATER AUTHORITY REVISED BASIC AGREEMENT TO ADDRESS PHASE V COST ALLOCATION CITY COUNCIL OF THE CITY OF CARLSBAD: Adopt Resolution No. amendment of the Encina Wastewater Authority Revised Basic Agreement to address Phase V cost allocation. 2004-213 approving ITEM EXPLANATION: At its meeting of June 2, 2004, the Encina Wastewater Authority (EWA) Joint Advisory Committee (JAC) approved an amendment of the Revised Basic Agreement to address Phase V cost allocation. The Joint Advisory Committee is now requesting the City Council’s review and approval of this amendment. The allocation of capital costs associated Encina Joint Facilities expansions is not within the express powers granted to the Encina Wastewater Authority by its Revised Establishment Document. The EWA is requesting that each member agency approve via resolution or minute motion the Encina Joint Facilities expansion capital cost allocation method as the basis for Phase V Expansion Project capital cost allocation. In late 2000, EWA staff met with member agency staff to describe the cost allocation model used in the Phase IV project (the Model) and to describe the operation of the Model when applied to Phase V Preliminary Design cost estimates. Subsequently, EWA conducted a review of the Model from an engineering and financial perspective. The findings of a report issued by EWA stated that the Model is: a) in substantial compliance with the Revised Basic Agreement (RBA), b) consistent with the Phase IV methodology; and, c) a reasonable method of allocating costs. In addition, the report made technical recommendations to improve the Model. An updated report issued by EWA in May 2004 included up- to-date audited financial records and added estimated Flow Equalization and Building Program costs to better estimate member agencies Phase V cash requirements. FISCAL IMPACT: The City of Carlsbad’s share to fund EWAs Phase V Expansion Project is $8,595,000. This amount is partially offset by a credit to the City of $1,088,000 for investments in existing EWA Unit I and Unit J facilities. These amounts were calculated using a five-step process which included; (1 .) determining each member’s share of replacement values for all existing Encina Joint facilities, (2.) adjusting ownership of existing Encina Joint facilities based on each member’s Phase V flow projections, (3.) applying debits or credits to each member which are determined by subtracting existing flow projections from adjusted flow projections, (4.) determining each member’s Phase V costs based on adjusted flow projections, then (5.) determining cash requirements of each member by applying a debit or credit to each member’s Phase V costs.

WOOD, City Clerk (SEAL) Resolution No. 2004-213 page 2 3 Encina Wastewater Authority Revised Basic Agreement Exhibit D Allocation of Phase V Capital Improvements The cost of Phase V Capital Improvements shall be allocated by unit process and among flow, Bio- chemical Oxygen Demand (BOD) and Total Suspended Solids (TSS) in the manner recommended for revenue programs by the State Water Resources Control Board as amended by action of the Encina Wastewater Authority (EWA) member agencies, Joint Advisory Committee and Board of Directors and as follows: 1. The replacement value of the existing Unit I and Unit J facilities at the mid-point of construction shall be determined and, in addition, each member agency’s share thereof shall be determined. a. Replacement value shall be calculated for all Unit I and Unit J facilities remaining in service at Phase V project acceptance including: Pre-Phase Ill; Phase Ill; Phase IV including interim flow equalization facilities transitioning from Unit J to Unit I; and, Post Phase IV including the Building Program and Joint Use Flow Equalization. b. The replacement value of each facility shall be calculated by multiplying the original cost of that facility by the percentage change in the Engineering News Record Construction Cost Index for Los Angeles (ENRLA) from the year that facility was placed in service then adding the resulting product to the original cost of the subject facility. Mid-Point of Construction shall be the date half-way between the date EWA issues a Notice to Proceed on the largest single Phase V Project construction contract and the date the EWA Board of Directors takes action to accept that contract as completed. Each member agency’s current ownership percentage (COP) of the replacement values for existing facilities shall be calculated by multiplying total Unit I Flow, Unit I Solids and Unit J Disposal replacement values by each member agency’s Unit I Liquid, Unit I Solids or Unit J Disposal percentage capacity rights as stated in Section 9.1 of the RBA. Based upon wastewater flow projections developed and refined by the member agencies, required ownership percentages (ROP) shall be determined and, in addition, each member agency’s share of existing facilities at replacement value determined in Step 1 shall be restated to conform to their respective ROP. a. Flow projections shall be provided by the member agencies and shall not be changed to alter the allocation of Phase V costs hereunder after the member agencies have unanimously approved this amendment to the Revised Basic Agreement (RBA). b. ROP shall be calculated by dividing a member agency’s wastewater flow projection by the total of all member agencies wastewater flows. Each member agency’s share of the replacement values for existing facilities shall be calculated by multiplying total Unit I Flow, Unit I Solids and Unit J Disposal replacement values by each member agency’s ROP of Unit I Liquid, Unit I Solids or Unit J Disposal. 3. An estimated debit or credit shall be calculated for each member agency to pay for, or receive payment or credit for, investments in existing Unit I and Unit J facilities and thereby reallocate ownership of existing facilities at replacement value among the member agencies in conformance with their respective ROP as determined in Step 2. a. Where any member agency’s ROP for Unit I Liquid, Unit I Solids or Unit J Disposal is greater than its COP for Unit I Liquid, Unit I Solids or Unit J Disposal, an estimated debit shall be calculated and assessed to that member agency’s account for that unit process. c. d. 2. c. F&HR 04-4126 9:Ol AM 611 612004 Encina Wastewater Authority Revised Basic Agreement - DRAFT -- Exhibit D Phase V Cost Allocation F&HR 04-4126 b. Where any member agency’s ROP for Unit I Liquid, Unit I Solids or Unit J Disposal is less than its COP Unit I Liquid, Unit I Solids or Unit J Disposal, an estimated credit shall be calculated and credited to that member agency’s account for that unit process. c. The debit or credit shall be calculated by subtracting each member agency’s share of the replacement values for existing facilities (determined in Step Id) by unit process from that member agency’s share of the ROP (determined in Step 2c) by unit process. d. Upon conclusion of this step for each unit process, each member agency’s estimated share of all Pre-Phase Ill, Phase Ill, Phase IV and Post-Phase IV Unit I and Unit J costs for facilities placed into, and remaining in, service as of the most recent fiscal year end prior to Phase V project acceptance shall be combined with the Phase V Project construction costs estimated in Step 4, to determine each member agency’s estimated Phase V Project cash requirements. 4. The total cost of the Phase V facilities at mid-point of construction shall be estimated by the design engineer. As of July 1, 2004 Phase V facilities construction costs are estimated at $36.1 million. These costs shall be allocated to member agencies on the basis of each member agency’s ROP. 5. Each member agency’s share of the total cost of the Phase V Project shall be calculated by adding the member agency’s debit or credit as determined in Step 3 with the member agency’s share of Phase V costs as determined in Step 4. These amounts as of July 1, 2004 are as follows (amounts in thousands of dollars): Estimated Estimated Total Estimated Replacement Existing Estimated Phase Phase V Cash Value of Existing Facilities Debit V Facilities Required by Ownership or (Credit) Costs Member Agency Vista $ 43,309 $ 7,270 $ 8,938 $ 16,209 Carlsbad $ 49,724 $ (1,088) $ 8,595 $ 7,507 Buena $ 16,742 $ (2,521) $ 2,513 $ (8) Vallecitos $ 40,565 $ 4,789 $ 8,590 $ 13,379 Leucadia $ 40,998 $ (7,294) $ 5,956 $ (1,338) Encinitas $ 9,689 $ (1,156) $ 1,508 $ 352 Total $ 201,026 $ O$ 36,100 $ 36,100 6. Final Phase V cost allocations shall be determined, and member agency accounts shall be adjusted in accordance with Section 17.3 of the RBA, following completion of Phase V construction and shall use the method described hereinabove except that actual figures shall be used including: existing facilities based on the most recently completed independent financial audit; project costs based on actual amounts paid according to EWAs financial records; and, actual ENRLA at the defined mid- point of construction.
