Dawes,Gary G.Streed and W.N.Clarke OTHERS PRESENT None ****************** Report of consultant re joint The Chair recognized Mr.Conrad Hohener sewage conveyance facilities to from Boyle Engineering Corporation,and serve Districts Nos.6,7 and 14 his associate Mr.Philip Stone,Districts’ consultants engaged to prepare a project report to select alignment,determine size and prepare cost estimates for joint sewage conveyance facilities to serve portions of District 7,the north half of District 6 and District 14.Mr.Hohener reported that the project report recently provided to the Directors was a culmination of several investigations, project reports and studies since 1983. 05/05/88 ~~~ Districts 6,7 &14 •~ .‘p.~ Originally,the firm had been engaged to do a preliminary study for District 7 and the north half of District 6~The work was suspended when it became evident that the Irvine Ranch Water District (IRWD)was going to request formation of a new Sanitation District to serve the Irvine area and join the Joint Administrative Organization~,District 14 was ultimately formed and the Main Street Trunk Sewer,Von Karman Trunk Sewer and Main Street Pump StatiOn were all sized to provide for the future flows of Districts Nos0 7 and 14~Flows have been transported through an interim connection to the Sunflower Interceptor Sewer0 He advised that the project report was basically completed last year; however,before it was presented to the Boards,they were directed to address a request from IRWD to upsize the Baker—Gisler Interceptor Sewer line~The “Revised”Project Report includes the upsizing and was prepared in cooperation with,and has been circulated to,the City of Costa Mesa,the Costa Mesa Sanitary District,the City of Irvine,the Irvine Ranch Water District and the County of Orange0 Three major alternative routes were considered and 27 subcombinations were studied before all of the agencies arrived at a consensus relative to the alignment0 The proposed project includes the construction of force main sewers and gravity trunk sewers from the Main Street Pump Station,located on the north side of Main Street within the John Wayne Airport “Clear Zone”to Reclamation Plant No0 1 in Fountain Valley0 The recommended sewer facilities include an 84—inch to 78—inch trunk sewer from Reclamation Plant No0 1 to Bristol Street in the City of Costa Mesa,sized for a peak flow of up to 103 million gallons per day;and dual Baker Street Force Mains,sized for a peak flow of 77 million gallons per day,extending from Baker Street at Bristol Street to the Main Street Pump Station0 The Baker—Gisler Interceptor Sewer,Contract No0 14—1—1,would be constructed jointly by Districts Nos.6,7 and 14;the Baker Street Force Mains,Contract No0 14-1—2,by Districts Nos.7 and 14.The double-barrel force main is proposed for the Baker Street Force Mains to maintain maximum flexibility,allowing one barrel to be in use in the early years of the project life to keep the velocities as high as possible,with the second barrel as backup0 In later years,both barrels would be used to reduce pumping energy costs0 In the event of an outage of one of the barrels,the second barrel would provide the reliability necessary during repairs0 Two 42—inch diameter pipe barrels are recommended for the dual force main system0 The Project Report also includes the District No0 6 parallel Fairview Relief Interceptor Sewer between Baker Street and Wilson Street to relieve the current facilities which are flowing at capacity.Initially,only the portion between Baker Street and the south side of the Paularino Flood Control Channel,a distance of about 800 feet,will be constructed. Mr.Stone further reviewed current and future capacity requirements of each District and gave a detailed explanation of the methodology used in determining the recommended capacity allocations.It was agreed that the Districts should continue their current policy of upsizing facilities, whenever possible,to allow for future capacity requirements. -2- ~O5/05/88 Districts 6,7 &14 It was pointed out that the agreement relative to formation of County Sanitation District No.14 provided that the construction of the joint conveyance facilities to service Districts Nos.6,7.and 14 be completed by 1990.Mr.Hohener commented that he believed this was an ambitious schedule but could be adhered to if the Boards moved forward with this program as soon as possible. The consultants then reviewed the total project cost for construction of the Baker—Gisler Interceptor Sewer,the Baker Street Force Mains and the Fairview Relief Interceptor Sewer,which is estimated to be $24,410,000.The costs are allocated to the benefiting Districts,based on pro—rata capacity requirements (including the upsizing requested by IRWO),as follows: CSO No.6 $3,680,000 CSD No.7 5,050,000 CSD No.14 15,680,000 Total $24,410,000 The Directors then entered into a discussion of the cost allocations.It was pointed out that the calculations,on a pro—rata basis in accordance with the Boards historical policy,and as provided in the District 14 formation agreement, reduces the cost per unit of capacity (mgd)for all participating Districts; decreases the total cost for Districts 6 and 7;but increases the total cost to District No.14 because of the allocation of all of the additional capacity to District 14 in response to the IRWD request for upsizing. IRWD requests that the upsizing costs be allocated to District 14 on an incremental basis rather than a pro—rata basis.Under this formula District 14 would pay only the incremental cost of upsizing the facilities.Thus Districts 6 and 7 would pay a higher cost per unit of capacity (mgd)than District No.14 but the same total cost calculated before the upsizing;and District 14 would pay a lower cost per unit of capacity and a lower total cost for the upsizing compared to the pro—rata method.Following further discussion,it was the consensus of the Directors that the cost allocation method would be reviewed by the Directors at a later date prior to a final determination on cost—sharing for these projects. The Directors also discussed the pump station capacities,the Von Karman and Main Street sewer capacities and the possibility of increasing the size of one or both of the Baker Street parallel force mains.The consultant advised that based on their studies,they recommended the two 42—inch lines and still felt that would best meet the Districts’needs.Increasing the size of one or both of the force mains may lead to operational problems.
