Site/Civil Engineering

Civil Site Planning and Engineering


Our Civil Site Engineering and Planning team has the expertise to provide every element of your project from conceptual plan preparation to utility layout to construction plans and specifications to permitting and regulatory and municipal approvals. As a full-service civil engineering and environmental consulting firm, we bring comprehensive solutions and problem-solving techniques to even the most complex issues.


Our team includes registered professional engineers, planners, designers, landscape architects, and inspectors with extensive sustainable site development and infrastructure design experience. We also have specialists available to assist with site feasibility studies, hydrologic and hydraulic studies, stormwater management and drainage design, utility analysis and design, landscape design, GIS mapping, and more.

Stormwater Expertise


We have significant experience with hydrologic and hydraulic analysis, planning and design. For example, we can model riverine system to define floodplains and determine the potential impacts of new developments on those floodplains. We can also take care of the recommendations and paperwork for FEMA and other regulatory agencies that accompany an alteration to a floodplain.


In North Carolina, we’ve created hydrologic and hydraulic models of dozens of dams as part of their dam safety program.


Our capabilities allow us to work on small, local drainage projects or vast, regional flood reduction strategies. Whether a single culvert needs replacement or an expansive sewer system requires upgrades, we are your stormwater experts.


 Economic Development Assistance


For almost a half a century, we have been an integral part of the economic development landscape throughout the Mid-Atlantic. From site characterizations and feasibility studies to master planning and final site design and even construction phase services, our team supports the success of localities at every stage of the development or redevelopment process.

Sustainable Design


From sustainability feasibility studies to identifying and documenting LEED® projects, we are ready to meet your green design needs. Our proven track record, innovative design techniques, and public information efforts set us apart as a leader in the field of sustainable design. We take great pride in our role in the first LEED® Platinum certified project in the Commonwealth of Virginia, VCU’s Rice Center Education Building.

Civil Information Modeling 


Pictured to the left, Civil Information Modeling (CIM) is 3D information modeling of utilities and site elements; think of it as BIM for the outside of the building’s footprint. Utilities are modeled during design using modern best practices for Subsurface Utility Engineering (SUE) with accurate size and location (X, Y, and Z). CIM allows for accurate design for new utilities and grading which prevents conflicts during construction that lead to additional cost and delays. Metadata can be added to items to identify additional information beyond the 3D representation. CIM and BIM can be integrated to create a holistic view of an entire project from design through construction, and beyond.
