This is a set of construction plans and specifications for the Entrada Way Culvert Slip-Out Bank Stabilization Project prepared by the County of San Mateo Public Works Department. The project involves comprehensive creek channel realignment, bank stabilization, and roadway improvements along La Honda Creek adjacent to Entrada Way. The scope of work includes clearing and grubbing operations, installation of erosion and sediment control measures (high visibility silt fencing, wildlife exclusion fencing, and stabilized construction entrances), temporary creek diversion systems with fish exclusion netting, excavation and dewatering of isolated work areas, installation of engineered log structures (ELS) with timber pilings, placement of scour protection rock and salvaged boulders, channel realignment with low-flow channel construction, roadway pavement removal and replacement, installation of drainage infrastructure including a 24-inch storm drain pipe, retaining wall construction with soldier piling and ground anchors, and riparian restoration through live stake and container plant installations. Sealed bids are due by 2:00 p.m. on Thursday, July 23, 2026, with public bid opening immediately following. Contractors must register on the OpenGov website to access all bidding documents and are required to submit a Plan Holder's Affidavit if obtaining documents through alternative sources. Questions regarding contract documents must be submitted in writing via email to mclement@smcgov.org and wng@smcgov.org by 5:00 p.m. on July 16, 2026, with responses posted to the County's Public Works website.

The plans indicate this is a complex multi-phase construction project requiring coordination of water management, environmental controls, and in-stream work activities. All temporary water management measures are preliminary schematics subject to contractor modification and engineer approval, with the contractor bearing sole responsibility for managing surface water and groundwater and submitting a Temporary Creek Diversion System Plan prior to commencing in-water work. Construction access is restricted to property 083-051-110 on the left (east) bank with all heavy equipment requiring crane placement into the work area. The project requires coordination with qualified biologists for fish exclusion and wildlife protection measures, and engineer inspections are mandatory at multiple stages including verification of clearing and grubbing limits, root zone protection installation, excavation extents, and key log placement before construction advancement. Tree surveys were completed November 5-6, 2024, and January 8, 2025, with specific tree removal protocols and protection requirements detailed throughout the plans.

HEN L. KAYSER WATER MANAGEMENT DETAILS

C06

SCALE:

DETAIL - COFFERDAM AND PIPE (EXAMPLE) 1

C05NTS

GENERAL NOTES:

1. WATER MANAGEMENT MEASURES SHOWN ON PLANS ARE A PRELIMINARY SCHEMATIC REPRESENTING ANTICIPATED SITE CONDITIONS.

THE CONTRACTOR SHALL ALTER WATER MANAGEMENT MEASURES AS NEEDED OR AS DIRECTED BY THE ENGINEER. THE

CONTRACTOR IS RESPONSIBLE FOR MEETING ALL PERMIT REQUIREMENTS.

2. BEFORE STARTING ANY WORK ON THE PROJECT, THE CONTRACTOR SHALL SUBMIT, FOR ACCEPTANCE BY THE ENGINEER, A WRITTEN PROGRAM INCLUDING WATER POLLUTION CONTROL PLAN (WPCP) AND APPLICABLE PLAN DRAWINGS AND DETAILS TO CONTROL

WATER POLLUTION EFFECTIVELY DURING CONSTRUCTION OF THE PROJECT.

3. IT SHALL BE THE SOLE RESPONSIBILITY OF THE CONTRACTOR TO MANAGE ALL SURFACE WATER AND GROUNDWATER, AND TO BYPASS ALL WATER THROUGH THE WORK AREA TO COMPLETELY ISOLATE THE WORK AREA FROM ACTIVE FLOW IN THE CREEK. THE CONTRACTOR SHALL PREPARE AND SUBMIT A TEMPORARY CREEK DIVERSION SYSTEM PLAN (TCDSP) PRIOR TO ANY IN-WATER WORK.

4. ALL TEMPORARY CREEK DIVERSION SYSTEMS EQUIPMENT SHALL BE LOCATED AND ALIGNED WITHIN THE PROJECT WORK AREA LIMITS.

5. LENGTH AND CONFIGURATION OF WORK AREA ISOLATION MEASURES NEEDED WILL VARY DEPENDING ON THE CONTRACTORS MEANS AND METHODS. CONTRACTOR SHALL DETERMINE THE NECESSARY LENGTHS NEEDED FOR THE WORK AREA AND BE RESPONSIBLE FOR DESIGNING, INSTALLING, OPERATING, MAINTAINING AND REMOVING ALL ISOLATION MEASURES.

6. CONTRACTOR SHALL CONSTRUCT WORK AREA ISOLATION MEASURES STARTING AT THE UPSTREAM END OF THE INTENDED WORK

AREA TO DIRECT WATER AWAY FROM THE WORK AREA.

7. THE ENGINEER SHALL BE NOTIFIED 24 HOURS IN ADVANCE OF ANY WATER PUMPING ACTIVITIES.

8. INSTALLATION OF ALL WATER MANAGEMENT MEASURES SHALL NOT CAUSE EXCESSIVE SEDIMENTATION, SILTATION, OR EROSION

UPSTREAM OR DOWNSTREAM OF THE PROJECT.

SCALE:

SECTION - COFFERDAM (EXAMPLE) A

C05NTS

FISH EXCLUSION NOTES:

1. PRIOR TO CONSTRUCTING AND OPERATING ANY WORK AREA ISOLATION MEASURE THE CONTRACTOR SHALL INSTALL FISH EXCLUSION

NETS AS DIRECTED BY A QUALIFIED BIOLOGIST WITHIN THE AREA TO BE ISOLATED. ALL FISH REMOVAL WORK SHALL BE COMPLETED BY A QUALIFIED FISHERIES BIOLOGIST. CONSTRUCTION WITHIN THE ISOLATED WORK AREA MAY NOT COMMENCE UNTIL ALL FISH EXCLUSION ACTIVITIES ARE COMPLETED. ALL TERMINAL ENDS OF FISH EXCLUSION NETS SHALL CONNECT TO THE TERMINAL ENDS OF HIGH VISIBILITY SILT FENCE (WITH WILDLIFE EXCLUSION). ALL TEMPORARY FISH EXCLUSION NETS INSTALLED BY THE CONTRACTOR MUST REMAIN IN PLACE DURING REMOVAL OF ISOLATION MEASURES AND OTHER TESC MEASURES. THE CONTRACTOR SHALL BE

RESPONSIBLE FOR REMOVING FISH EXCLUSION NETS.

2. FISH RELOCATION SHALL BE CONDUCTED BY COUNTY QUALIFIED FISHERIES BIOLOGISTS PRIOR TO INSTALLING THE TEMPORARY

CREEK DIVERSION SYSTEMS.

3. FISH EXCLUSION BLOCK NETS SHALL BE PROVIDED BY THE COUNTY AND INSTALLED BY THE CONTRACTOR IN CONSULTATION WITH THE QUALIFIED BIOLOGIST. BLOCK NETS SHALL BE MAINTAINED BY THE CONTRACTOR BOTH UPSTREAM AND DOWNSTREAM OF THE DIVERSION, THROUGHOUT THE PERIOD OF CONSTRUCTION. MAINTENANCE INCLUDES PERIODIC REMOVAL OF ACCUMULATED DEBRIS, AS NECESSARY TO ENSURE FUNCTION. BLOCK NETS SHALL BE REMOVED AFTER THE DIVERSION IS REMOVED AND THE IN CHANNEL

WORK AREA IS RE-WATERED.

DEWATERING NOTES:

1. WATER ENCOUNTERED DURING EXCAVATIONS AND WITHIN THE ISOLATED WORK AREAS MAY BE PUMPED AS NECESSARY TO BAKER

TANK(S), OR SIMILAR, SHOWN ON THE PLANS TO ALLOW FOR THE CONSTRUCTION OF THE ELSs AND PLACEMENT OF SCOUR PROTECTION ROCK, AND TO FACILITATE THE REMOVAL OF SEDIMENT AND TURBIDITY FROM THE WATER PER APPROVAL BY THE ENGINEER. ANY DISCHARGE OF WATER RETURNING FROM THE BAKER TANK(S), OR SIMILAR, BACK INTO LA HONDA CREEK (DUE TO DEWATERING ACTIVITIES) SHALL ADHERE TO THE WATER QUALITY REQUIREMENTS SET FORTH IN THE PROJECT PERMITS.

2. DEWATERING WATER MAY BE PUMPED TO THE BAKER TANK(S), OR SIMILAR, AND DISCHARGED THROUGH AN ENERGY DISSIPATOR, LEVEL SPREADER, FILTER SOCK, SILT BAGS, OR OTHER AS APPROVED BY THE ENGINEER. WATER DISCHARGED OR INFILTRATED

SHALL NOT CAUSE EROSION OR RESULT IN TURBIDITY IMPACTS TO LA HONDA CREEK.

3. DEWATERING WATER MAY NOT BE PUMPED DIRECTLY TO THE CREEK CHANNEL WITHOUT PRIOR WRITTEN APPROVAL FROM THE ENGINEER. WATER SHALL BE DISCHARGED IN ACCORDANCE WITH THE PLANS, SPECIFICATIONS AND PERMITS.

4. DEWATERED ISOLATION WORK AREA CONFIGURATION SHOWN IN WATER MANAGEMENT PLANS ARE TYPICAL AND MAY BE SUBJECT TO

CHANGE DEPENDING ON DRAINAGE NEEDS WITHIN THE PROJECT LIMITS.

5. ALL PUMPS USED FOR DEWATERING SHALL BE SCREENED IN ACCORDANCE WITH THE FISH SCREENING CRITERIA .
