Flora_Survey_Record_Drawings_-_230318.pdf

These are record drawings for Charles County Landfill No. 2, Subcell 4A, located in Charles County, Maryland, prepared by Flora and Atlantic Lining Company, Inc. The documents comprise 11 technical sheets including a cover sheet, site plan, subgrade plan, thickness maps comparing different layers, leachate collection zone plan, and leachate transmission pipe plan. The drawings detail the construction specifics for Subcell 4A, showing existing cells (Cells 1, 2A, and 3A), future subcell locations, and the precise geological and infrastructure layout for the landfill expansion project.

The drawings provide extensive technical details including topographical contour lines, elevation markers, construction zone boundaries, and specifics about leachate collection infrastructure. The documents include geomembrane assessment details, with red markers indicating normal repairs and destructed areas, and gray markers showing repair locations along the new sections. The technical specifications appear to be part of a precise engineering documentation set for the landfill cell construction, with multiple layers of infrastructure planning including subgrade, sand top layer, and leachate transmission systems. The drawings are dated and stamped by Flora, with detailed scale measurements and comprehensive technical annotations throughout the documents.
