Santa Ana Blvd. Grade Separation <br />AT &T <br />AT &T's facilities are located along Santiago Street, Logan Street, Fuller Street, and Fruit <br />Street. A short segment is also located under the SARTC parking area south of Santa <br />Ana Boulevard. <br />Verizon <br />Verizon overhead lines are located along Lincoln Avenue, Fuller Street and Fruit Street. <br />Metrolink <br />Metrolink's telecommunication and signal control cables are located within the railroad <br />right of way and along the railroad tracks. <br />Impacts to existing utilities are mainly as a result of depressing Santa Ana Boulevard <br />roadway profile limiting the ability of utilities along side streets to continue across Santa Ana <br />Boulevard. To that end, the following strategies are proposed: <br />City of Santa Ana: <br />Water: The 12" waterline under Santa Ana Boulevard will be relocated to a proposed <br />parallel utility corridor north of Sana Ana Boulevard. This will allow the waterline to <br />maintain existing ground profile as the utility corridor will not be depressed. Minor <br />waterlines along the side streets to the north will also be able to retain their connectivity <br />to the 12" waterline. East of Fuller Street, the 20" waterline will be relocated behind the <br />northerly retaining wall. Additional study is needed to determine if the 8" waterline under <br />Fuller Street south of Santa Ana Boulevard can be removed. <br />Sewer: Although the existing OCSD trunk main can remain in place underneath the <br />SARTC parking area, connectivity to sewer service lines from Logan Street, Lincoln <br />Avenue, and Fuller Street will be disrupted by the depressed Santa Ana Boulevard <br />roadway profile. As a result, a 12" sewer is proposed to be placed in the same utility <br />corridor to collect service lines from the north and reconnect to the OCSD trunk line near <br />Santiago Street. It is noted that since the proposed 12" line will be at a higher elevation <br />at Lincoln Avenue /Railroad crossing, the existing sewer service line along Lincoln <br />Avenue /Railroad will need to be reconstructed at a higher elevation as well. <br />Dry Utilities (Eletric, Telephone, and Gas): <br />Due to a general lack of dry utilities located within Santa Ana Boulevard, existing dry <br />utilities can be generally protected in place. It is noted that the utility corridor will allow <br />for the protection of existing SCE underground line paralleling Santa Ana Boulevard. <br />Additional coordination efforts are need in the next phase of the project. <br />5.8 Cost Estimate <br />A detailed cost breakdown for the preferred alternative is included as Attachment I. The <br />following table summarizes the cost for the construction and support components. <br />PROJECT REPORT EQUIVALENT 19E -21 12 <br />
