three methods: horizontal directional drilling, traditional tunneling and micro - tunneling, The project was installed using the micro - tunnel method under a 100 -foot deep hill adjacent to Carbon Canyon Dam. The remainder of the pipeline was installed using open trench construction. Portions of the project were located behind the Carbon Canyon Dam, which is owned and operated by the U.S. Army Corps of Engineers and used for flood control purposes. Dense vegetation existed behind the dam, which consisted . primarily of ornamental plants, annual grassland, a small amount of riparian habitat, chaparral, and coastal sage scrub, The pipeline alignment was developed to minimize impacts on the heavily vegetated . area and environmentally sensitive areas while still achieving the desired facility objectives. The project Included environmental analysis, geotechnical investigation, the preparation of a Preliminary Design Report consisting of wastewater flow projections from all land tributary to the sewer, hydraulic analysis, alignment study, easement research, utility research, odor control analysis, flow monitoring, final design, and traffic control, AW Mesawater DISTRICT Client Reference: Mr. Phil Lauri, P.P. District Engineer Mesa Water District 949- 631 -1206 �orr; Mesa Water District - On -Cali and Related Services REP has been serving Mesa Water District in multiple capacities out of our Irvine office. We were recently awarded an on -call services contract for supporting Mesa on various water related projects, in which we have recently provided hydraulic modeling support, and mapping /right-of -way support. In addition to water related services, REP has been providing. GIS services (Steve Bein) and permitting regulatory (Rich Beck) support to Mesa in various capacities, OC -44 Pipeline Rehabilitation/Replacement Project. As a separate project, RBF also provided a preliminary engineering study on the 8.4 mile OC -44 pipeline for Mesa Water District that focused on two major goals: 1) Evaluate rehabilitation and replacement alternatives for the portion of the pipeline crossing the San Diego Creek and recommend the best means of protecting the pipeline from future failures within the creek; 2) Assess the condition of the entire 8.4 miles of transmission main, and evaluate the potential for installing a cathodic protection system. As part of this study, RBF also evaluated alternative water supply scenarios, developed summaries of the regulatory permitting and CECIA compliance processes, and is preparing a critical: path :schedule for final design and construction. rho port nP LONG EE Re.
