Work effort included preliminary engineering <br />nalysis of alternatives including five rehabilitation options and seven replacement alignments. Michael Baker also <br />conducted a habitat assessment 10 document baseline conditions and closely evaluate the p flontial for the adopt <br />site to support any state or fe kinut listed sensitive species. Mass Water reviewed the opposed shemadves antl <br />selected sliplining a 30-inch diameter pipeline inside the existing 42-inch pipe. Michael Baker drafted design plans <br />for the diftemdidation method and provided bid phase sem W s. Michael Baker Is providing can phase <br />services and construction is scheduled for completion in 202oe <br />The project is pad of a multi phase pipeline project that connects the future Magic Mountain Reservoir to the future <br />Magic Mountain Pump Station, originally divided into six phases. Phase 6 is the last segment of transmission <br />pipeline that connects Me Phase 5 pipeline to the future Magic Mountain Reservoir within the future development <br />known as 'Mission Village- by FivePoint. Due to development phasing, the project was divided into two design <br />packages —6A and 68. Si Water retained Michael Baker to provide final design services for the entire Phase 6 <br />segment In Me preliminary design phase Of each segment, Michael Baker analyzed several different alignment <br />alternatives in coordination who the SCV Water and Fividienrs consultants. Final design of the entire project <br />Includes Me following tasks: design of 6,WO-feel of 42-inch cement panne, lined and coated (CMLSC) steel pipe <br />and supinchPVC schedule 40 Ober optic conduit valve vaults wild 42-inch motor actuated bufiedy valves, a <br />private reservoir access pad and corrosion monitoring improvements. <br />This project Is a Sub Area Master Plan (SAME) Update to the previous analysis and report performed in 200B. As <br />a pad of the 2017 update, which required approval by MINE, new analyses were conducted for IM1e existing and <br />Proposed Potable Water, Recycled Water, and Wastewater Collection Systems to identify any deficiencies based <br />an IBM service and performance criteria. Furthermore, ackloonal anatysis of each system was performed based <br />on proposed constpcfion phasing Ir refine ultimate facility sizing as wall as required off site system imme provents. <br />Based on the respite of the system analysis, a detailed cast estimate for capital and noncapida( improvements On <br />ppposed facilities was developed. Recently two addendums to the SAME Update were completed by Michael <br />Baker to address development and phasing iterations which necessitated a focused analysis wind the larger <br />development area. <br />C f! <br />Michael Baker provided design and construction phase suppor services for a 4 0 MG recycled water and two 2.0 <br />MG domestic water reservoirs. All three reservoirs were of welded steel construction. In addition, Michael Baker <br />designed approximately 25,000 LF (combined) of contest and required water CMLSC steel transmission mains, <br />ranging in size tram 20-inch to 30 inch in diameter. TM1e project also tnduded the design of approximately 275,000 <br />wbtc yards of coupling for the tank sites and access mad. The Parginct included an a0emafive alignment analysis <br />1-7 <br />suppon to secure environmental approvals, and <br />Drinking haler. The tanks serve the Rancho Mission Viejo Planning Areas 1, 2 and 3. <br />domestic water reservoir on a combined site. Both reservoirs were of welded steel conslpction. Michael Baker <br />also designed approximately 23,000 LF (combined) of 2Tmch domestic water nd 20-inch recycled water Cci <br />steel transmission mains. The project also included the design of approximately 31 moo cubic yards of grading for <br />the tank sties antl access road The pmji access mad .,and relocation of a proton of the 18-inch Coto de <br />Casa Trunk Sewer and development of a phasing 8 bypass plan to maintain continuous sewer flows. The project <br />included technical suppon to Secure environmental approvals, and coordination with Division of Drinking Wafer. <br />The tanks serve IM1e Rancho Mission Viejo Planning Areas 2 and 3. <br />will PI sinly P ctming consuuawn engineering support services. the chant provides drinking water to <br />duslome s located within a 510-mile distdd of wastem Riverside County. Water resources include (healed suface <br />water and treated grountlwater. The surface water is imported from Northern Califomia and treated at the Mills <br />waferbealment plant. The local groundwater is treated at the Chino II Dodder and the Arington Desaltec Michael <br />Baker assisted in designing facilities to transfer healed groundwater Ira a residential area of In district where <br />customers are currently receiving water from the Mills water treatment plant ony including a new 1 S MG concrete <br />reservoir and a high-pressure pumping station When completed, the facilities will allow the client to transfer up ld <br />20 cubic feel per second of "died groundwater from the desalination plants Is the area. The work included PAID <br />development, SCADA, and electrical distribution and controls dion, <br />station in Anaheim, Long Beach, Seal Beach, Cypress. Buena Park, and Los Alamitos; a total of Bg00o musinfichat <br />f <br />of sewer line. Michael Bakers services include a ufilify survey and research, surveying and mappdg', a pipeline <br />rehabilitation analysis; preparation of at estimates and calculated, modeling in Civil 313; and preparation of <br />technical memoranda and opera. contract drawings and details, and contract spsu ications. As a subco portent <br />to another engineering find, Michael Baker is providing design support retina rehabilitation of Reach 1, the Orange - <br />Western Sub -Trunk Sewe, Reach 1 has a nominal pipe diameter of 214nches and an overall length of <br />approximately 13 941inearfeel. Designer and constructed in 1950, the Reach 1 pipeline begins at the Intersection <br />of Valley View and Orange Avenue and continues east for approximately 7,935 feel to Western Avenue. The <br />pipeline Men continues north on Western Avenue for aWmxdmadely 6,023 feet to a manhole located in the street <br />between Santa Domingo Way and Santa Elena Brive. There are approximately 38 manholes within these segmenls <br />of pipeline, neatly all requiring replacement to meet current district standards.
