THE PURPOSE OF THIS PUBLIC NOTICE IS TO INFORM INTERESTED PARTIES OF THE PROPOSED ACTIVITY AND TO SOLICIT COMMENTS. NO DECISION HAS BEEN MADE AS TO WHETHER OR NOT A PERMIT WILL BE ISSUED AT THIS TIME.

This District has received an application for a Department of the Army permit pursuant to Section 10 of the Rivers and Harbors Act (33 USC 403) and Section 404 of the Clean Water Act (33 USC 1344),as described below:

APPLICANT:

                                    Nancy L. Trippe
                                    27386 Trippe Road
                                    Easton, Maryland 21601

WATERWAY AND LOCATION OF THE PROPOSED WORK:

The proposed work is located in the Tred Avon River in Easton, Talbot County, Maryland. (Project: Latitude 38.75535; Longitude -76.11981).

OVERALL PROJECT PURPOSE:

To provide shoreline erosion protection and to establish/enhance habitat along the shoreline at 27386 Trippe Road in Easton, Talbot County, Maryland.

PROJECT DESCRIPTION:

The applicant proposes, in accordance with the attached plans, to stabilize a total of approximately 685 linear feet (lf) of eroding shoreline using a living shoreline design, all within an approximately 31,493 square foot (sf) (0.72 acre) impact area as follows: to construct 620 lf of low profile stone sill by emplacing 657 cubic yards (cyds) of stone, and 1,023 cyds of clean sand fill backfill stabilized with 19,469 sf (0.45 acres) of native low and high marsh species. The stone sill will incorporate vents to allow tidal exchange landward of the sill; 2-inch diameter gravel will be placed in the vents to an elevation between mid-tide and minus -0.5 ft mean high water (MHW) to reduce scour at the sill openings. In addition, approximately 200 sf of stone scour protection would be emplaced along 685-lf foot section of shoreline at the upper limits of the existing tidal marsh to reduced undercutting. The work would extend a maximum of 67 ft channelward of the approximate MHW shoreline.

All work is proposed in accordance with the attached plans as prepared by Rauch, Inc. dated October 1, 2019. Please refer to the table below for a summary of aquatic resource impacts.

LEAD FEDERAL AGENCY:

The United States Army Corps of Engineers (Corps), Baltimore District, as the lead federal agency, is responsible for all coordination pursuant to applicable federal authorities.

APPLICANT’S PROPOSED AVOIDANCE, MINIMIZATION, AND COMPENSATORY MITIGATION:

As part of the planning process for the proposed project, steps were taken to ensure avoidance and minimization of impacts to aquatic resources to the maximum extent practicable based on the existing site conditions.

The project shoreline is situated off the Tred Avon River with an approximately 1.6-mile southern fetch exposure. The existing estuarine marsh areas are eroding between approximately 0.1 and 1.5 ft/year. The applicant has minimized the channelward extent of the proposed fill and structures to the maximum extent practical whereby reducing overall impacts to existing tidal wetlands and documented submerged aquatic vegetation (SAV) by the Virginia Institute of Marine Science for the most recent 5 years of mapped coverage data. The total channelward encroachment of approximately 67 ft and proposed displacement of approximately 3,131 sf of a sparse SAV beds (2020) represents the minimum necessary to dampen approaching wave energy and protect existing and proposed irregularly flooded marsh. The SAV impacts represent approximately 18 percent of the 2020 mapped SAV bed aerial coverage data. SAV was not mapped in 2015-2019, 2021, or 2022.

The project proposes to backfill with sand within the existing gaps of irregularly flooded marsh as enhancement. The proposed construction impacts within these existing eroding marsh areas would be temporary in duration. Temporarily disturbed marsh areas would be restored to preexisting conditions/wetland elevations and revegetated with native low to high marsh species upon completion of shoreline stabilization activities.

No compensatory mitigation is proposed. No wetlands would be permanently impacted as a result of the proposed project. Impacts to SAV are minimal as they represent a small percentage of a transient, sparse SAV bed mapped in a single year over the last 10 years, therefore no compensatory mitigation for SAV impacts is proposed at this time. The proposed project upon completion would result in a net gain of approximately 15,133 sf of intertidal marsh.

CORPS EVALUATION REQUIREMENTS:

This project will be evaluated pursuant to Corps Regulatory Program Regulations (33 CFR Parts 320-332). The decision whether to issue a permit will be based on an evaluation of the probable impacts, including cumulative impacts of the proposed activity on the public interest. That decision will reflect the national concern for both protection and utilization of important resources. The benefit, which reasonable may be expected to accrue from the proposal, must be balanced against its reasonably foreseeable detriments. All factors, which may be relevant to the proposal will be considered, including the cumulative effects thereof; among those are conservation, economic, aesthetics, general environmental concerns, wetlands, cultural values, fish and wildlife values, flood hazards, flood plain values, land use, navigation, shoreline erosion and accretion, recreation, water supply and conservation, water quality, energy needs, safety, food and fiber production, mineral needs, and consideration of property ownership and in general, the needs and welfare of the people. The evaluation of the impact of this project will also include application of the Clean Water Act Section 404(b)(1) Guidelines promulgated by the Administrator, the United States Environmental Protection Agency.

ENDANGERED SPECIES:

A preliminary review of this application indicates that the proposed work is not likely to adversely affect federally listed threatened or endangered species or their critical habitat, pursuant to Section 7 of the Endangered Species Act, as amended. The project site has been mapped as migrating and foraging habitat for subadult and adult Atlantic sturgeon (Acipenser oxyriynchus oxyriynchus); migrating and foraging habitat for adult shortnose sturgeon (Acipenser brevirostrum); and migrating and foraging habitat for adult and juvenile Green sea turtle (Chelonia mydas), Kemp’s ridley sea turtle (Lepidochelys kempii), Leatherback sea turtle (Dermochelys coriacea), and Loggerhead sea turtle (Caretta caretta). The project location and vicinity are not mapped as critical habitat for any known federally listed threatened or endangered species under United States Fish and Wildlife Service’s jurisdiction. As the evaluation of this application continues, additional information may become available which could modify this preliminary determination.

ESSENTIAL FISH HABITAT:

The Magnuson-Stevens Fishery Conservation and Management Act (MSFCMA), as amended by the Sustainable Fisheries Act of 1996 (Public Law 04-267), requires all federal agencies to consult with the National Marine Fisheries Service on all actions, or proposed actions, permitted, funded, or undertaken by the agency that may adversely affect Essential Fish Habitat (EFH), including species of concern, life cycle habitat, or Habitat Areas of Particular Concern. The project site lies in or adjacent to EFH as described under MSFCMA designated in Chesapeake Bay for little skate (Leucoraja erinacea), Atlantic herring (Clupea harengus), red hake (Urophycis chuss), windowpane flounder (Scophthalmus aquosus), winter skate (L. ocellata), clearnose skate (Raja eglanteria), bluefish (Pomatomus saltatrix), and summer flounder (Paralichthys dentatus); all managed species under the MSFCMA. The Corps has made a preliminary determination that the project will not have a substantial adverse effecton EFH. The Corps has made a preliminary determination that mitigative measures are not required to minimize adverse effects on EFH at this time. This determination may be modified if additional information indicates otherwise.

HISTORIC RESOURCES:

Pursuant to Section 106 of the National Historic Preservation Act of 1966 and applicable guidance, the Corps has reviewed the latest published version of the National Register of Historic Places and initially determined that no registered properties listed as eligible for inclusion, therein, are located at the site of the proposed work. The Corps has made the preliminary determination that the proposed project would have no adverse effect on historic properties. The Corps final eligibility and effect determination will be based on coordination with the State Historic Preservation Office as appropriate and required, and with full consideration given to the proposed undertaking’s potential direct and indirect effects on historic properties within the Corps’ identified permit area.

TRIBAL RESOURCES:

Section 106 of the National Historic Preservation Act also requires federal agencies to consult with federally recognized American Indian tribes that attach religious and cultural significance to historic properties that may be affected by the agency’s undertaking. Corps Tribal Consultation Policy mandates an open, timely, meaningful, collaborative, and effective deliberative communication process that emphasizes trust, respect, and shared responsibility. The policy further emphasizes that, to the extent practicable and permitted by law, consultation works toward mutual consensus and begins at the earliest planning stages before decisions are made and actions taken. The Corps final eligibility and effect determination will be based on coordination with interested tribes, in accordance with the Corps current tribal standard operating procedures as appropriate and required, and with full consideration given to the proposed undertaking’s potential direct and indirect effects on tribal resources.
