Environmental Planning & GIS

SEPI staff have an understanding of environmental rules and regulations and have developed and maintained solid resource agency relationships.

SEPI’s environmental team consists of scientists, engineers, surveyors, and planners dedicated to providing timely, cost-effective, and high quality planning, permitting, assessment, design, implementation, and maintenance services. Our team has expertise in multiple environmental disciplines including hydraulics, hydrology, soils, surveying, vegetation, aquatic species, geospatial analysis and modeling, CAD based site design models, stakeholder outreach and coordination, planning, permitting, and construction oversight. We balance the needs of diverse stakeholders with preserving and protecting the natural and human environment. Our environmental planners and scientists work side-by-side with our engineers throughout the life of a project, continually analyzing and documenting a project’s implications on land use and the environment.

“The A-E (SEPI) had exceptional communication with the government through meetings, telephone calls and email. The A-E also was very cooperative in accomplishing the goals of the project.“  — Teresa Russell, Biologist, USACE, for preparation of Environmental Assessment for Albemarle to Highway 200 project
