This project will rehabilitate and reconstruct the entire length of the Orange Western Sub -trunk, Los <br />Alamitos Sub -trunk, Westside Relief Interceptor and Seal Beach Boulevard Interceptor. The sewer lines <br />are located in the western most portion of the Orange County Sanitation District (OCSD) service area <br />including the Cities of Anaheim, Cypress, Los Alamitos, Seal Beach and La Palma. The project is <br />approximately 16 miles and includes 217 manholes. The project goal is to extend the service life of the <br />sewer system by an additional 50 years. <br />T2 is providing SUE services in accordance with ASCE 38-02 to support the design of the sewer <br />rehabilitation. Services include records research and creation of the utility base map (Quality Level D), <br />geophysical utility investigation, survey (Quality Levels C and B) and test holes (Quality Level A). <br />Included in the utility investigation is approximately 30,000 LF of designating and up to 1,000 test holes. <br />Information obtained during the field investigations and surveys will be used to update the Utility Map <br />and qualify the depicted alignments. Deliverables include Utility Plan Sets, AutoCAD Civil 3D files and <br />Test Hole Data Reports. <br />This project increases the size of the upper reaches of the existing <br />Newhope-Placentia Trunk Sewer to provide additional capacity for <br />future flows projected with new development that allow for the <br />abandonment of the Yorba Linda Pumping Station. This includes the <br />abandonment of the wastewater disposal company sewer originally <br />constructed in the early 1900s and is now owned by the OCSD. The <br />project includes 34,800 LF of pipe, 18" to 36" VCP and 49" to 42" RCP <br />located within State College Boulevard from the Cal State Fullerton <br />campus continuing to Angel Stadium. <br />T2 staff provided full SUE services to support design of the Newhope- <br />Placentia Trunk Sewer Replacement including utility records research, <br />utility mapping and potholing services (ASCE 38-02 Quality Levels D, <br />C, B and A). Crews designated and mapped all utilities in approximately <br />7 miles of State College Boulevard (Anaheim and Fullerton) and <br />completed over 400 test holes. Final deliverables included Utility Base <br />Maps identifying subsurface utility alignments, ASCE 38 Quality Levels <br />of the alignments, Test Hole Data Sheets and Photo Logs. <br />T2 staff provided SUE (potholing) services (ASCE 38-02 Quality Levels <br />B and A) to map the horizontal and vertical position of underground <br />utilities to support design of water, sewer and reclaimed water design <br />projects. Utilities located include petroleum, data transmission, <br />telephone, gas, electric, water and sewer pipelines. <br />T2's team completed over 600 (Quality Level A) test holes. <br />1.
