This is a soils boring location plan prepared by John D. Hynes & Associates, Inc. for the County Commissioners of Charles County, Maryland. The document, dated August 2, 2018, is Appendix D of the NPDES Oak Ridge Park East Stream Restoration project and displays the boring locations at the project site. The plan is drawn to a scale of 1 inch equals 260 feet and identifies five boring locations (labeled E-1 through E-5) positioned across the project area at Oak Ridge Park, located at 13675 Oaks Road, Hughesville, in Charles County, Maryland. These boring locations were established to support the geotechnical investigation and soils analysis necessary for the stream restoration design.

The NPDES Oak Ridge Park East Stream Restoration project involves construction services for installing a stormwater detention facility and restoring approximately 1,400 linear feet of an actively eroding unnamed tributary channel to Gilbert Run through in-stream and bank stabilization structures. The project scope also includes stabilization of approximately 120 linear feet of an eroding outfall channel. All work must comply with Charles County Government's Department of Planning and Growth Management Standards & Specifications for Construction, the Charles County Details Manual, County Ordinances, and applicable Local, State, and Federal regulations. The County Commissioners sought sealed bids from qualified contractors to perform the construction services, with work encompassing all improvements and modifications shown on the approved Construction Plans.
