Credit: Marine Robotics and Remote Sensing, Duke University. 1 Abstract In accordance with the National Environmental Policy Act (NEPA, 42 U.S.C. 4321 et seq.) and the National Marine Sanctuaries Act (NMSA, 16 U.S.C. 1434), the National Oceanic and Atmospheric Administration’s (NOAA) Office of National Marine Sanctuaries (ONMS) has prepared a Draft Environmental Impact Statement (DEIS) that considers alternatives for the proposed designation of Mallows Bay-Potomac River as a National Marine Sanctuary. The proposed action addresses NOAA’s responsibilities under the NMSA to identify, designate and protect areas of the marine and Great Lakes environment with special national significance due to their conservation, recreational, ecological, historical, scientific, cultural, archaeological, educational, or aesthetic qualities as national marine sanctuaries. ONMS has developed four alternatives for the designation and the DEIS evaluates the environmental consequences of each alternative under NEPA. The DEIS also serves as a resource assessment under the NMSA, documenting present and potential uses of the areas considered in the alternatives. NOAA’s preferred alternative (Alternative C) would designate a 52 square mile area of the waters and bottomlands of the tidal Potomac River for the protection of at-risk, nationally-significant shipwrecks and associated maritime heritage resources. No significant adverse impacts to resources and the human environment are expected under any alternative. Long term beneficial impacts are anticipated if the proposed designation is finalized.

Mail: Paul Orlando, Regional Coordinator, Northeast and Great Lakes Region, 410 Severn Ave, Suite 207-A, Annapolis MD 21403. 2 3 4 About This Document This draft environmental impact statement (DEIS) analyzes impacts and evaluates a reasonable range of alternatives (including a no action alternative) associated with the proposed designation of Mallows Bay- Potomac River as a National Marine Sanctuary. This document is also a resource assessment document that details the present and future uses of the areas identified for possible designation. The National Oceanic and Atmospheric Administration (NOAA) prepared this DEIS in accordance with the National Environmental Policy Act of 1969 (NEPA; 42 USC 4321 et seq.) as implemented by the Council on Environmental Quality regulations (40 CFR Parts 1500-1508), and NOAA Administrative Order (NAO) 216-6A, which describes NOAA policies, requirements, and procedures for implementing NEPA. Accordingly, this document was preceded by a Notice of Intent to prepare a draft environmental impact statement (DEIS) and carry out a public scoping process (80 FR 60634; Oct. 7, 2015). The public scoping period commenced in October 2015 and ended on January 15, 2016, during which time public meetings were held and NOAA received both written and oral comments on the concept of designating a sanctuary. NOAA received approximately 186 comments during that scoping period, strongly supportive of the concept. NOAA is the lead agency for this action. NOAA’s Office of National Marine Sanctuaries (ONMS) is the implementing office for this action. The cooperating agency for the development of this DEIS is the U.S. Department of Navy.

The project was undertaken as an initiative of the National Park Service Chesapeake Bay office, which supports and manages the Captain John Smith Chesapeake National Historic Trail. One of the goals of the Captain John Smith Trail is to interpret Native life in the Middle Atlantic in the early years of colonization by Europeans. The Indigenous Cultural Landscape (ICL) concept, developed as an important tool for identifying Native landscapes, has been incorporated into the Smith Trail’s Comprehensive Management Plan in an effort to identify Native communities along the trail as they existed in the early17th century and as they exist today. Identifying ICLs along the Smith Trail serves land and cultural conservation, education, historic preservation, and economic development goals. Identifying ICLs empowers descendant indigenous communities to participate fully in achieving these goals.

This settlement was originally the site of the Indian Village of Potopaco. Port Tobacco was the first county seat, but after the river began silting up and after a shift of occupations from tobacco farming to other trades and industry people moved to the town of La Plata where the new railroad was being built. The county seat was eventually moved to La Plata. The first Charles County Courthouse was completed in 1729, and a second one in 1819.

    David Clickner, et ux. v. Magothy River Association, Inc., et al. No. 13, September Term, 2011, Opinion by Greene, J. REAL PROPERTY LAW – PRESCRIPTIVE EASEMENTS – Public prescriptive rights may be acquired over privately owned portions of beaches located along inland waterways. It was error, however, for the trial court, under the circumstances of this case, to apply the general presumption of adversity to the public use of a beach that was unimproved and in a general state of nature. Instead, the proper presumption was that public use of the land was by permission of the owners. Therefore, the burden was on the claimants to overcome the presumption of permission by proving that the use was, in fact, adverse. IN THE COURT OF APPEALS OF MARYLAND No. 13 September Term, 2011 DAVID CLICKNER, et ux. v. MAGOTHY RIVER ASSOCIATION, INC., et al. Bell, C.J. Harrell Battaglia Greene Adkins Barbera *Murphy, Joseph F., Jr. (Retired, specially assigned), JJ. Opinion by Greene, J.

Following a bench trial on the merits, the trial judge determined that Appellees had demonstrated the existence of a prescriptive easement on behalf of the public and ordered the removal of portions of a fence erected on the beach by Appellants.

Thompson Principal Investigator Maryland Department of Planning Maryland Historical Trust, Office of Archeology Maryland State Historic Preservation Office 100 Community Place Crownsville, Maryland 21032-2023 November, 2005 This project was accomplished through a partnership between the following organizations: Maryland Historical Trust Maryland Department of Natural Resources Martinak State Park Chesapeake Bay Maritime Museum Maritime Archaeological and Historical Society *The cover photo shows the entrance to Watts Creek where the Martinak Boat was discovered just to the right of the ramp http://www.riverheritage.org/riverguide/Sites/html/watts_creek.html (accessed December 10, 2004). Executive Summary The 1960s discovery and recovery of wooden shipwreck remains from Watt’s Creek, Caroline County induced three decades of discussion, study and documentation to determine the wrecks true place within the region’s history. Early interpretations of the wreck timbers claimed the vessel was an example of a Pungy (generally accepted to have been built ca. 1840 – 1920, perhaps as early as 1820), with "…full flaring bow, long lean run, sharp floors, flush deck…and a raking stem post and stern post" (Burgess, 1975:58). However, the closer inspection described in this report found that the floors are flatter and the stem post and stern post display a much longer run (not so raking as first thought). Additional factors, such as fastener types, construction details and tool marks offer evidence for a vessel built earlier than 1820, possibly a link between the late 18th-century shipbuilding tradition and the 19th-century Pungy form.

Governor Mark Belton, Secretary Tidewater Ecosystem Assessment Joanne Throwe, Deputy Secretary Potomac River Water Quality and Habitat Assessment Overall Condition 2012-2014 The Potomac River watershed includes area in Maryland, Virginia, Pennsylvania, West Virginia and Washington D.C. For the purpose of this report, the basin is divided into four regions: the Upper Potomac, Shenandoah, Middle Potomac and Lower Potomac (Figure 1). Land use in the upper Potomac River watershed was estimated to be 69% forest and 22% agriculture (Figure 1, Table 1).1 The Upper Potomac watershed is largely within West Virginia (54%), with other portions in Pennsylvania (22%), Maryland (18%) and Virginia (7%). Impervious surfaces cover 1% of the Maryland potion of the Upper river basin (Table 1).2 Land use in the Shenandoah watershed was estimated to be 56% forest and 34% agriculture. The Shenandoah watershed is almost entirely in Virginia (96%), with a small area in West Virginia (4%). Land use in the Middle Potomac watershed was estimated to be 44% agriculture, 32% forest and 20% developed. The Middle Potomac watershed includes areas in Maryland (55%), Virginia (34%), Pennsylvania (13%) and Washington D.C. (0.1%). Impervious surfaces cover 7% of the Maryland potion of the Middle river basin. Land use in the Lower Potomac watershed was estimated to be 41% forest, 30% developed, and 16% agriculture.

  • II. Background
    II. Background This chapter provides background information that was used as a basis for formulating the Preliminary Subregion 5 Master Plan and Proposed Sectional Map Amendment. Section A, Planning Context and Process, describes the location of the study area, the purposes of this master plan, prior plans and initiatives, and the public process used to prepare this master plan. Section B, Existing Conditions, contains profiles of Subregion 5 including the area’s history, demographic, economic, environmental, transportation and land use information. Section C, Key Issues, summarizes the key planning issues that are addressed in this master plan. A. Planning Context and Process Master Plan Study Area Boundaries The master plan study area includes land in south and southwest Prince George’s County generally bounded by the Potomac River, Tinkers Creek, Andrews Air Force Base, Piscataway Creek, the CSX (Popes Creek) railroad line, Mattawoman Creek, and the Charles County line.
