Wade is retired from the NRCS in Virginia, where he most recently served as assistant state conservationist managing the water resources programs and completing nine dam rehabilitation projects. From 1990 to 2001, he was coordinator for watershed planning in Virginia, including flood control, water quality, and land treatment projects. Wade is a repository of experience and knowledge pertaining to NRCS watershed rehabilitation policies and procedures, NEPA requirements, and how to work successfully with sponsors; stakeholders; the public; and government agencies.
Joseph Monroe, PE
Joe has been exclusively involved in the design of new dams, design of remedial measures for existing dams, and construction of dam and dam related components for the last 20 years. His design experience includes subsurface explorations and geotechnical evaluations, hydrologic and hydraulic analyses, hydraulic and structural design of spillways, and preparation of bidding and construction documents. Joe has been involved with dam projects throughout the United States and numerous countries throughout the world. In addition to design, He is recognized by the FERC as an Independent Consultant for Part 12D inspection of dams. Joe recently served as the Project Manager and Lead Engineer for a contract with the USACE Norfolk District supporting their Nationwide Dam Safety Program.
James Crowder, PE
Jimmy has over 20 years of experience in the design and construction of new dams, and for the rehabilitation of existing dams. He has served as project manager, reviewer, lead inspector, or lead engineer on more than 50 high-hazard dam projects, including 25 dam assessments for Georgia NRCS and 25 principal spillway video inspection reports for Tennessee NRCS. Current projects include the design and construction of spillway and embankment rehabilitations for the Soque River Watershed Dam Nos. 29 and 36; Bull Creek Watershed Dam Nos. 12 and 14, supporting Georgia NRCS in their development of a supplemental watershed plan and environmental evaluation.
Petr Masopust, PE, CFM
Petr brings more than 15 years of professional experience, having served in numerous roles a senior engineer and assistant project manager on numerous NRCS projects, including engineering analyses for development of Supplemental Watershed Project Plans for dams in Massachusetts and Pennsylvania, dam assessments in Massachusetts, and dam rehabilitation of George H. Nichols Dam in Massachusetts.
