About this file
This document consists of contract drawings for the Cox Creek Dredged Material Containment Facility (DMCF) Capacity Recovery project managed by the Maryland Port Administration's Office of Navigation, Innovation, and Stewardship in Anne Arundel County, Maryland. The project seeks to recover approximately 50,000 cubic yards of dredged material from the Cox Creek DMCF through innovative contractor-proposed solutions. The drawings, dated November 26, 2025, include a site plan with vicinity and location maps, existing conditions documentation, staging and material dewatering areas, and detailed topographical information for both the upland cell and waterside cell components of the facility. The contract drawings reference project number 1-26-5-18-8 and are based on survey data collected via small unmanned aircraft systems (sUAS) and field surveys conducted between December 2024 and July 2025, with the most recent dredged material surface survey completed on October 3, 2025.
The drawings establish technical specifications using the North American Datum of 1983 (2011) for horizontal reference and Mean Lower Low Water (MLLW) for vertical datum, with elevations referenced to NOAA's tidal station 8574680 for the 1983-2001 tidal epoch. The facility includes an upland cell with sediment basin and sump area, a waterside cell, a north-south cross dike, an unloading pier, staging and material dewatering areas, contractor trailer and operations areas, and an operations and maintenance complex. The dredging area shown on the plans is considered approximate and incorporates a general buffer from the toe of existing interior dikes, with the final dredging area to be determined by the Engineer in Charge (EIC). The drawings indicate inaccessible areas and multiple access roads throughout the facility, with contour intervals of 2.0 feet on the site plan and 1.0 feet on the staging and material dewatering area plan.

GENERAL NOTES
UPLAND CELL:
1) THE TOPOGRAPHY OF THE DIKE SLOPES AND ALIGNMENT SHOWN HEREON IS BASED
ON SMALL UNMANNED AIRCRAFT SYSTEMS (sUAS) SURVEY DATA COLLECTED BY MES
ON 6/4/25, AND SURVEY FIELD DATA COLLECTED BY MES ON 6/17/25 (SEDIMENT
BASIN-A).
2) THE TOPOGRAPHY OF THE UPLAND CELL BASIN SHOWN HEREON IS BASED ON sUAS
SURVEY DATA COLLECTED BY MES ON 7/15/25, AND SURVEY FIELD DATA COLLECTED
BY MES ON 7/24/25 (SUMP AREA).
3) DUE TO SITE CONDITIONS AT THE TIME OF SURVEY INCLUDING STANDING WATER AND
UNSTABLE MATERIAL, A PORTION OF THIS SURFACE HAS BEEN LIMITED TO THE
APPROXIMATE WATER SURFACE ELEVATION (-10.25 FT).
WATERSIDE CELL AND NORTH SOUTH CROSS DIKE (NSCD):
4) THE TOPOGRAPHY OF THE DIKE SLOPES AND ALIGNMENT SHOWN HEREON IS BASED
ON sUAS SURVEY DATA COLLECTED BY MES ON 12/13/24.
5) THE TOPOGRAPHY OF THE DREDGED MATERIAL SURFACE SHOWN HEREON IS BASED
ON QUARTERLY SURVEY FIELD DATA COLLECTED BY MES ON 10/3/25.
6) THE DREDGING AREA SHOWN HEREON IS CONSIDERED APPROXIMATE AND
INCORPORATES A GENERAL BUFFER FROM THE TOE OF THE EXISTING INTERIOR DIKES.
FINAL DREDGING AREA WILL BE DETERMINED BY THE ENGINEER IN CHARGE (EIC).
7) HORIZONTAL DATUM: NORTH AMERICAN DATUM OF 1983(2011) (NAD 83/11)
8) VERTICAL DATUM: MEAN LOWER LOW WATER (MLLW). VERTICAL DATUM REFERENCED
TO THE NATIONAL OCEANIC AND ATMOSPHERIC ADMINISTRATION (NOAA), NATIONAL
OCEAN SERVICE (NOS) TIDAL STATION 8574680 FOR THE 1983-2001 TIDAL EPOCH.
