Written by GovTribe AI · Aug 7, 2026

This document is a set of construction plans for the Long Beach Public Utilities Department in Long Beach, California, prepared by Atkins Realis for the Rancho Los Alamitos Transmission Main Abandonment Project. The project encompasses the abandonment of existing water transmission mains from E Bixby Hill Road to E 7th Street, with construction planned for July 2026. The scope includes abandonment of existing 24-inch steel cylinder concrete (SCC) and steel water lines in place using controlled low-strength material (CLSM), installation of line stops for temporary pipeline isolation, welding of steel blind flanges to existing pipes, installation of blow-off assemblies at dead ends, and removal of various water valves, access manholes, and utility appurtenances. The project involves multiple valve isolation points, including temporary closure of several gate valves and permanent abandonment of others, with coordination required between the contractor and Long Beach Public Utilities Department for all valve operations and system maintenance during construction.

The construction plans specify detailed technical requirements including hydrostatic testing to 188 PSI, disinfection and bacteria testing per ANSI/AWWA C651-23 standards, and compliance with LBUD water and sewer standards. The contractor is required to submit a water supply bypass plan for approval prior to construction, maintain fire protection and traffic control, provide potable water for service interruptions exceeding four hours, and coordinate all work activities with LBUD and other utility providers listed in the plans. Construction costs and contract award information are not included in these design plans; the document serves as the technical specification and construction guidance for the project implementation. The project is identified by contract number WD-07-26 and MUNIS project number 6512030005, with design approval dated July 29, 2029 by licensed engineer Stella Shao.

NOTES:

1. PROPERTY BOUNDARIES, RIGHT-OF-WAY LIMITS, LOT LINES, EASEMENTS, AND

EXISTING UTILITY LOCATIONS SHOWN HEREON ARE BASED ON AVAILABLE RECORD

DRAWINGS AND GIS DATA PROVIDED BY LBUD AND HAVE NOT BEEN VERIFIED BY FIELD

SURVEY. THESE FEATURES ARE APPROXIMATE AND ARE PROVIDED FOR REFERENCE

ONLY. CONTRACTOR SHALL FIELD VERIFY THE HORIZONTAL AND VERTICAL LOCATION

OF ALL UTILITIES AND OTHER EXITING CONDITIONS, INCLUDING PROPERTY LINES AND

EASEMENTS, AS NEEDED PRIOR TO CONSTRUCTION. ANY DISCREPANCIES SHALL BE

BROUGHT TO THE ENGINEER'S ATTENTION FOR RESOLUTION.

2. CONTRACTOR SHALL TAKE ALL PRECAUTIONARY MEASURES TO PROTECT IN PLACE

AND SUPPORT ALL EXISTING UTILITIES WITHIN PROXIMITY UNLESS OTHERWISE NOTED.

3. CONTRACTOR SHALL DISINFECT AND PERFORM BAC-T TEST PIPING, INCLUDING ANY

PIPES AND LATERALS DISCONNECTED AND RECONNECTED, PER ANSI/AWWA C651-23,

PRIOR TO RECONNECTION PER AGENCY REQUIREMENTS. FOR LATERALS,

DISINFECTION AND TESTING SHOULD BE MINIMUM UP TO THE NEAREST VALVE OR AS

REQUIRED BY LBUD. SEE SPECIFICATION SECTION 33 13 00 FOR CHLORINATION OF

WATER MAINS FOR DISINFECTION.

4. CONTRACTOR SHALL SUBMIT TO LBUD A WRITTEN REQUEST TO DEWATER THE

PIPELINE TWO (2) WEEKS IN ADVANCE OF THE VALVE REPLACEMENT. LBUD WILL BE

RESPONSIBLE FOR CLOSING ALL THE DESIGNATED SHUT-DOWN VALVES AND THE

CONTRACTOR WILL BE RESPONSIBLE FOR DEWATERING THE PIPELINE. THE

CONTRACTOR SHALL BE EXPECTED TO PUMP OUT REMAINING NUISANCE WATER IN

THE PIPE AND DISCHARGE THE WATER TO EXISTING STORM DRAIN CATCH BASINS.

5. EXISTING LARGE GATE VALVES AND CONCRETE ANCHOR BLOCK UNDER THE VALVE

BODY TO BE REMOVED. CONTRACTOR TO REMOVE AND DISPOSE OF THE CONCRETE

ANCHOR BLOCK.

6. CONTRACTOR TO ABANDON EXISTING ACCESS MANHOLE, BY REMOVING LID, RISER,

TOP 2-FEET OF CONCRETE MANHOLE AND BACKFILL AND COMPACT. THE VOID MUST

BE FILLED WITH APPROVED MATERIALS, SUCH AS TYPE II BORROW OR FLOWABLE FILL,

AND COMPACTED TO MEET 90-95% RELATIVE COMPACTION. THE ABANDONED AREA

MUST BE BACKFILLED TO EXISTING GRADE IN UNDEVELOPED AREAS OR PAVED PER

CITY STANDARD IN DEVELOPED AREAS.

7. A POTHOLE INVESTIGATION WAS PERFORMED AT SELECT LOCATIONS ALONG THE

PROJECT ALIGNMENT TO BETTER INFORM EXISTING SUBSURFACE CONDITIONS, WITH

ONLY PARTIAL CONFIRMATION VERIFIED. THE CONTRACTOR SHALL NOT RELY SOLELY

ON THE POTHOLE DATA FOR CONSTRUCTION AND SHALL PERFORM INDEPENDENT

VERIFICATION OF ALL EXISTING UTILITIES AND SUBSURFACE FEATURES AS

NECESSARY TO COMPLETE THE WORK. SEE APPENDICES IN SPECIFICATIONS FOR

FULL POTHOLE REPORT AND SUPPORTING DOCUMENTATION.

8. CONTRACTOR TO FIELD VERIFY THE STEEL PIPE CYLINDER THICKNESS AND ASSESS

THE CONDITION OF PIPE PRIOR TO WELDING. CONFIRM PIPE IS INTACT AND

SUFFICIENT STEEL THICKNESS EXISTS TO SUPPORT PROPOSED WELDING

OPERATIONS AS SHOWN IN THE PLANS.
