Home Browse Search

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