Written by GovTribe AI · Jan 29, 2026

This is a technical drawing set prepared by the Maryland Environmental Service (MES) for the Poplar Island Land Base Dredging and Pier Improvement project located in Tilghman, Maryland. The project involves the removal of accumulated sediment from three boat slips (Osprey, Spartina, and Egret/Terrapin) surrounding the personnel pier and the design, fabrication, and installation of a wave screen. The dredging work encompasses approximately 1,363 square feet with a total volume of 55 cubic yards of material to be removed and transported by barge to the Poplar Island Dredged Material Containment Facility (DMCF). The Osprey Slip requires dredging to a depth of -4.0 feet Mean Low Water (MLW), while the Spartina Slip requires dredging to -3.0 feet MLW. The property, consisting of 1.33 acres and owned by MES since November 6, 2006, is located within the Chesapeake Bay Critical Area and the 100-year floodplain in a limited developed area. The drawings include existing conditions survey data from April 2025, location and vicinity maps, detailed dredging plans, profile sections, and wave screen specifications using horizontal datum NAD 83/11 and vertical datum Mean Low Water.

The wave screen specifications are noted as approximate in the drawings, with final specifications to be provided after contract award. The proposed wave screen is designed to comply with regulations and will not diminish tidal flow or impact Bay bottom. Contractors are advised that particular attention must be given to limits of work in areas near existing structures, with all costs for repair of damage to any structure or features to be the sole responsibility of the contractor. The drawings were surveyed and prepared by MES personnel with data collection conducted in June 2014 for existing features and April 2025 for topographic and bathymetric properties, with tidal wetland extents surveyed in August 2025.

NOTES

1) THE MARYLAND ENVIRONMENTAL SERVICE (MES) PERFORMED A SITE SURVEY TO

DETERMINE EXISTING FEATURES INCLUDING PROPERTY LINES, SHORELINES,

EXISTING PIERS AND OTHER STRUCTURES IN JUNE 2014, AND TOPOGRAPHIC AND

BATHYMETRIC PROPERTIES IN APRIL 2025. MES IS NOT RESPONSIBLE FOR ANY

INACCURACIES ASSOCIATED WITH LOCATIONS OF THE ABOVE REFERENCED

FEATURES. THIS DRAWING IS FOR PERMIT PURPOSES AND AS A CONSTRUCTION

DOCUMENT AND IS NOT TO BE USED AS A NAVIGATIONAL AID.

2) THE TIDAL WETLAND EXTENTS SHOWN HEREON ARE BASED ON SURVEY FIELD

DATA COLLECTED BY MES IN AUGUST 2025.

3) THE ENTIRE PROPERTY IS LOCATED WITHIN THE CHESAPEAKE BAY CRITICAL AREA

AND THE 100 YEAR FLOODPLAIN.

4) THE ENTIRE PROPERTY IS LOCATED IN A LIMITED DEVELOPED AREA.

5) LAND BASE LOT SIZE 1.33 ACRES.

6) MES IS THE PROPERTY OWNER SINCE 11/06/2006.

7) MES CAN MAKE NO WARRANTY AS TO ACTUAL CONDITIONS;

CONTRACTOR/BIDDERS SHALL MAKE ITS OWN INVESTIGATION OF CONDITIONS.

8) CONTOUR INTERVAL: 1.0'

9) HORIZONTAL DATUM: NORTH AMERICAN DATUM OF 1983(2011) (NAD 83/11)

10)VERTICAL DATUM: MEAN LOW WATER (MLW). ELEVATION RELATES TO TIDAL
