April 15, 2020 Mr. Joseph Davia Chief, Maryland Section Northern US Army Corps of Engineers Baltimore District Regulatory Branc April 15, 2020 Mr. Joseph DaVia Chief, Maryland Section Northern US Army Corps of Engineers Baltimore District Regulatory Branch 2 Hopkins Plaza Baltimore MD 21201 Ms. Amanda Sigillito Division Chief Maryland Department of the Environment Wetland and Waterways Program Nontidal Wetlands Division 1800 Washington Boulevard Baltimore MD 21230 Dear Mr. DaVia and Ms. Sigillito: The Maryland Department of Transportation State Highway Administration (MDOT SHA) is submitting a Joint Federal/State Application and supporting documentation for the Alteration of Any Floodplain, Waterway, Tidal or Nontidal Wetland within the Limits of Disturbance (LOD) of the Build Alternatives of the I-495 & I-270 Managed Lanes Study (MLS), located in Montgomery and Prince George’s counties in Maryland and Fairfax County in Virginia (see attached Vicinity Map). This application is submitted pursuant to the requirements of the Code of Maryland Regulations, Sections 26.17 and 26.23, and Section 404 of the Clean Water Act and supported by the publicly available MLS Draft Environmental Impact Statement. One original and six copies of the following documents are enclosed for review and processing of this permit request: • Joint Permit Application, Tier II Checklist, and Billing Approval Form • Impact Plates • United States Army Corps of Engineers (USACE) Impact Tables • Maryland Department of the Environment (MDE) Impact Tables Supporting information for this permit application has been posted to the project’s FTP site, accessible via the following link: https://sftp1.mdot.state.md.us/ The login is: Username: NEPAUSACE Password: pthreeuser1 * Please note, the FTP site works best using Google Chrome 707 North Calvert St., Baltimore, MD 21202 | 410.637.3320 | 1.833.858.5960 | Maryland Relay TTY 800.735.2258 | roads.maryland.gov Mr. Joseph DaVia Ms. Amanda Sigillito Page Two Supporting information includes: • Online Mapping Tool Link and Login Information • Wetland Delineation Memo • Avoidance, Minimization, and Impacts Report • Draft Compensatory Mitigation Plan MDOT SHA is proposing the MLS to provide a travel demand management solution(s) that addresses congestion and improves trip reliability on I-495 and I-270 within the Study limits and enhances existing and planned multimodal mobility and connectivity. The extent of the MLS on I-495 is from in the vicinity of the George Washington Memorial Parkway in Fairfax County, Virginia to west of MD 5 in Prince George’s County and on I-270 from I-495 to I-370, including the east and west I-270 spurs. Six Build Alternatives, Alt 8, Alt 9, Alt 9M, Alt 10, Alt 13B, and Alt 13C, are being considered and each Build Alternative includes construction activities that would result in unavoidable impacts to wetlands and waterways, including: roadway widening and reconfiguration, additional drainage improvements, staging and stockpiling areas, construction access areas, culvert extension and augmentation, outfall stabilization, and bridge replacement. Project activities would occur within the following 16 Maryland 12-digit watersheds: Potomac River/Rock Run, Cabin John Creek, Rock Creek, Sligo Creek, Northwest Branch, Paint Branch, Little Paint Branch, Northeast Branch, Bald Hill Branch, Upper Beaverdam Creek, Upper Southwest Branch, Lower Southwest Branch, Watts Branch, Muddy Branch, Beaverdam Creek, and Henson Creek. The MLS Build Alternatives would result in a range of USACE and MDE impacts. The impacts associated with each Build Alternative are shown on the impact plates and included in the impact tables. If you need further assistance, please contact Ms. Caryn J. G. Brookman, MDOT SHA I-495 & I-270 P3 Office Environmental Program Manager, at 410-637-3335 or via email at [email protected].

    Defining the Indigenous Cultural Landscape for The Nanjemoy and Mattawoman Creek Watersheds Prepared By: Scott M. Strickland Virginia R. Busby Julia A. King With Contributions From: Francis Gray • Diana Harley • Mervin Savoy • Piscataway Conoy Tribe of Maryland Mark Tayac • Piscataway Indian Nation Joan Watson • Piscataway Conoy Confederacy and Subtribes Rico Newman • Barry Wilson • Choptico Band of Piscataway Indians Hope Butler • Cedarville Band of Piscataway Indians Prepared For: The National Park Service Chesapeake Bay Annapolis, Maryland St. Mary’s College of Maryland St. Mary’s City, Maryland November 2015 ii EXECUTIVE SUMMARY The purpose of this project was to identify and represent the Indigenous Cultural Landscape for the Nanjemoy and Mattawoman creek watersheds on the north shore of the Potomac River in Charles and Prince George’s counties, Maryland. 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.

  • 2010-2015-Data-Summary-Report
    1 The Audubon Naturalist Society is pleased to offer this report of water quality data collected by its volunteer monitors. Since the early 1990s, the Audubon Naturalist Society (ANS) has sponsored a volunteer water quality monitoring program in Montgomery County, Maryland, and Washington, DC, to increase the public’s knowledge and understanding of conditions in healthy and degraded streams and to create a bridge of cooperation and collaboration between citizens and natural resource agencies concerned about water quality protection and restoration. Every year, approximately 180-200 monitors visit permanent stream sites to collect and identify benthic macroinvertebrates and to conduct habitat assessments. To ensure the accuracy of the data, the Audubon Naturalist Society follows a quality assurance/quality control plan. Before sampling, monitors are offered extensive training in macroinvertebrate identification and habitat assessment protocols. The leader of each team must take and pass an annual certification test in benthic macroinvertebrate identification to the taxonomic level of family. Between 2010 and 2015, ANS teams monitored 28 stream sites in ten Montgomery County watersheds: Paint Branch, Northwest Branch, Sligo Creek, Upper Rock Creek, Watts Branch, Muddy Branch, Great Seneca Creek, Little Seneca Creek, Little Bennett Creek, and Hawlings River. Most of the sites are located in Montgomery County Parks; three are on private property; and one is in Seneca Creek State Park. In each accompanying individual site report, a description of the site is given; the macroinvertebrates found during each visit are listed; and a stream health score is assigned. These stream health scores are compared to scores from previous years in charts showing both long-term trends and two-year moving averages.

Descriotion: Tenmile Creek Road, one of but a few dirt roads remaining in le County, winds past a nineteenth century schoolhouse, a slave cabin, a fire- ~:~oof house built on the site of a turreted mansion destroyed by fire in 1945, a Victorian summer boarding house and private park, a mid-nineteenth century mill site and pond, and a deserted, early road. The road leads through a green valley where jersey cows graze, up a gentle rise and around a bend where the trees meet overhead, through a ford, to the intersection with West Old Baltimore Road and a pond of pink and yellow water lilies. The creek valley contains numerous natural springs, many lined with watercress, meadows of wildflowers, surrounded with tree covered hills. 10. Significance: The valley of Tenmile Creek, immediately northwest of Boyds, Md. is an uncompromised historic & environmentally significant area that has suc­ ceeded in maintaining its character. Saved from development, it is now threatened by an impoundment. Historically the area contains potentially signifi­ cant archeological sites -- possibly of prehistoric Indian culture -- associated with woodland settlements of eighteenth century tobacco planters, a mill site, pond, race & house, a large boarding house constructed to accommodate summer visitors after the area became accessible by railroad in 1873, & later structures erected by dairy farmers.
