This document is a set of design drawings for the Richmond Harbor Channel FY26 Maintenance Dredging Project in Contra Costa County, California, prepared by the U.S. Army Corps of Engineers San Francisco District.

The project involves dredging Richmond Inner Harbor to a project depth of -37 feet MLLW (Mean Lower Low Water) across 14 acceptance reaches spanning from Station 0+21 to Station 237+00, with a total channel length of approximately 2.37 miles. Dredging must achieve specified depths with allowable overdepth tolerances: 1.0 foot paid overdepth and 2.0 feet total allowable overdepth. The dredged material will be delivered to the government-furnished Montezuma Wetland Offloader, with provisions for alternate placement sites if delays exceed 24 hours. Critical environmental considerations include eelgrass monitoring requirements for Reaches 5 through 9 and Reaches 11, 12, and 13, with a 250-meter eelgrass buffer zone maintained throughout the project area. Utility crossings, including a submarine sewer pipeline at approximately -55 feet depth operated by West Coast Agency, must be located and verified before dredging commences. The project uses California State Plane Coordinate System Zone 03 for horizontal positioning and MLLW for vertical datum, with bathymetric survey data current as of March 3, 2026. Solicitation number W912P726RA020 with contract number W912P726CXXXX was issued in July 2026, and the drawings include detailed dredging plans, channel control point tables, and cross-sectional details across multiple plan sheets covering the entire project corridor.

GENERAL NOTES:

1. ALL REACHES MUST BE DREDGED TO THE PROJECT DEPTH AS SPECIFIED. WHEN DREDGING

TO THE REQUIRED DEPTH IN AREA WHERE A UTILITY CROSSING EXISTS, DREDGING MUST BE

DONE IN ACCORDANCE WITH SPEC 01 11 00. BEFORE STARTING WORK, THE CONTRACTOR

SHALL LOCATE AND VERIFY ALL UNDERWATER AND OVERHEAD UTILITIES. WORK MAY ONLY

BEGIN AFTER THESE LOCATIONS ARE CONFIRMED AND SAFE WORK LIMITS HAVE BEEN

ESTABLISHED. THE UTILITY CROSSINGS SHOWN ON THE DRAWINGS REFLECT USACE'S

KNOWLEDGE OF EXISTING UTILITIES.

2. BATHYMETRIC SURVEY FOR RICHMOND INNER HARBOR WAS CONDUCTED BY THE U.S. ARMY

CORPS OF ENGINEERS, SAN FRANCISCO DISTRICT, ON 03 MARCH 2026.

3. BATHYMETRIC SURVEY SOUNDINGS ARE BASED ON THE DATUM OF MEAN LOWER LOW WATER

(MLLW) AT THE LOCALITY.

4. DRAWINGS ARE NOT TO BE USED AS NAVIGATION CHARTS.

5. INFORMATION SHOWN ON THE DRAWINGS IS BASED ON BATHYMETRIC SURVEYS MADE ON

THE DATES INDICATED AND CAN ONLY BE CONSIDERED INDICATING THE GENERAL

CONDITIONS EXISTING AT THAT TIME.

6. BATHYMETRIC SURVEY SOUNDINGS WERE TAKEN BY FATHOMETER (MULTI-BEAM SURVEY

EQUIPMENT) AND ARE SHOWN TO THE NEAREST TENTH OF A FOOT.

7. COORDINATES ARE BASED ON THE CALIFORNIA STATE PLANE COORDINATE SYSTEM OF 1983

(CCS83), LAMBERT CONFORMAL PROJECTION ZONE III, AS DESCRIBED IN SPECIAL

PUBLICATION NO. 253, PUBLISHED BY NATIONAL OCEAN SURVEY.

8. THE PROJECT DEPTH FOR REACH 1 TO REACH 14 IS -37 FT MLLW. THE DELIVERY SITE WILL BE

THE MONTEZUMA WETLAND OFFLOADER EXCEEDING 24 HOURS, THE GOVERNMENT MAY

DIRECT THE CONTRACTOR TO AN ALTERNATE GOVERNMENT FURNISHED PLACEMENT SITE.

9. THE LOCATION OF ALL NAVIGATION AIDS ARE BASED ON INFORMATION PROVIDED BY THE U.S.

COAST GUARD. BUOY LOCATION REPRESENTS THE POSITION OF THE SINKER ONLY.

12. RICHMOND INNER HARBOR POST-CONSTRUCTION EELGRASS SURVEY WAS CONDUCTED ON

07 APRIL 2025 BY MERKEL & ASSOCIATES INCORPORATED. REACHES 5 THROUGH 9 ALONG

WITH REACHES 11, 12, AND 13 REQUIRE EELGRASS LIGHT MONITORING. THE CONTRACTOR

SHALL REFERENCE THE SPECS FOR INFORMATION ABOUT EELGRASS SURVEYS.

CONTRACTOR SHALL CONDUCT EELGRASS MONITORING FOR THE ENTIRE AREA OF THE

REACH THAT REQUIRES EELGRASS MONITORING.
