Williamsburg Environmental Group, Inc. (WEG) offers a wide range of water resources capabilities and has years of experience in providing comprehensive environmental and water resources/stormwater infrastructure engineering services for projects of various scale and complexity. Our professional staff includes a diversified group of civil/water resources engineers, hydrologists, soil scientists, ecologists, environmental planners, landscape architects, and regulatory specialists who strive to develop cost effective solutions for clients' water resources needs.
WEG has extensive experience in providing stormwater management planning and design, hydrologic & hydraulic modeling, water quality protection, Clean Water Act permitting, watershed planning, drainage analyses, floodplain modeling and mapping, and Low Impact Development techniques to clients in both the public and private sectors. Our staff creates solutions compatible with the land plan and the natural environment by applying state of the art computer models and technology.
Below are brief descriptions of some of the specific services WEG offers, followed by a complete list of our water resources capabilities and a few project showcases.
Stormwater Management Planning and Design |
WEG prepares Stormwater Management Plans to mitigate potential water quantity and quality impacts associated with land use changes. Plans range from small-scale individual projects to regional programs. These plans are developed to ensure all local, state, and federal regulations are satisfied. Stormwater solutions include Best Management Practices (BMPs) and Integrated Management Practices (IMPs) to provide quality and quantity control. Plans identify the most appropriate BMP locations and types based on aesthetics, feasibility, cost, environmental impacts, regulatory issues, and project phasing. Once a feasible plan is complete, WEG provides detailed construction plans for the proposed BMPs. WEG also provides Erosion and Sediment Control Plans or Pollution Prevention Plans for construction activities. |
Water Quality Assessments |
WEG has prepared numerous Water Quality Impact Assessments (WQIA) to be in accordance with the objectives of the Chesapeake Bay Preservation Area Ordinance, as adopted by the specific locality. As part of the WQIA, our staff complete a natural resource inventory in which the proposed land use plan and best management practices are reviewed along with the existing and future hydrogeological, vegetative, utility, and landscaping components. |
Floodplain Analysis |
WEG's team of planners and engineers provide floodplain analysis and floodplain alteration studies, as well as permits necessary to determine appropriate options for the site development. The floodplain extent is the greatest flood height or still-water level estimated to occur based on a 100-year storm event. The floodplain area often contains wetlands and soil suitable for wetland creation. these created wetlands can be sold to other developers, who are required to comply with federal, state, and local regulations, or can be used as on-site mitigation. |
Water Supply Studies |
WEG performs water supply and demand studies, which provide our clients with an understanding of the balance between anticipated demands and available water supplies. A computer model developed by WEG computes potential demands based on local climate data and evaluates potential water sources for meeting deficits. Typical water supply studies identify demands and potential water sources and evaluate each source with respect to availability, cost, and environmental impacts. |
Dam Design and Dam Safety Compliance |
WEG has a staff of a dozen engineers that have proven experience in dam safety engineering services such as dam and spillway design, dam safety permitting and certification, dam breach analysis, and inundation mapping. WEG has worked on more than 75 recent dam projects including both new construction and dam rehabilitation in Virginia. WEG's experience includes GIS-integrated hydrologic and hydraulic modeling on multiple platforms including WMS, HEC-HMS, HEC-RAS, and a variety of other software systems. WEG's modeling capabilities are extensive and include experience in spillway design and optimization, flood routing and dam breach hydraulic modeling modeling for unsteady flow conditions. |
