Fill Slope Movement at Newport Estates, Section 5D – Woodbridge, Prince William County, Virginia

WDP was retained by Prince William County Public Works to review, investigate, and evaluate the probable cause of a 50-foot high fill slope movement that was compromising the stability and safety of several residential dwellings near the top of the slope.  In addition to site and building monitoring, WDP’s services required geotechnical investigations using test borings, inclinometers and groundwater piezometers, laboratory testing, evaluation and analysis, and preparation of a written report of opinion with remedial design recommendations.  WDP was also requested to assist with slope repair design implementation and oversight to stabilize the slope and mitigate any further slope or building movements.
