Environmentally Sensitive Solutions for Today's Engineering Challenges.
Horsley Witten Group helps non-profit, private, and municipal clients solve complex civil and environmental engineering challenges. Civil engineering services include environmental, survey-GIS, construction administration, and permitting. We specialize in green stormwater infrastructure, site design, water supply, shoreline stabilization, streambank restoration, wastewater planning and design, and coastal resiliency.
We take a big-picture approach to every project. As a science-based firm, we apply the basic principles of hydrology, chemistry, soil science, biology, and ecology to all our engineering designs. Bringing the right expertise together early helps keep projects on track and avoid unnecessary costs. Our engineers enjoy collaborating with other design professionals to provide innovative design solutions for the environmental challenges within our communities.
“Horsley Witten has provided us excellent service in landscape architecture, civil engineering, and permitting over the past ten years. They are professional, courteous, and timely.”

Areas of Expertise
Our civil engineering team brings specialized knowledge across a broad range of project types, with particular depth in sustainable infrastructure and coastal resilience.
Stream Restoration
Many of our rivers and streams have taken quite a beating over the years from increased stormwater flows, vegetative buffer loss, and channel alterations.
Shoreline Resilience
Rising seas, increased storm intensity, and shifting sands can wreak havoc on our coastal beaches. Community investments in living shorelines, dune stabilization, and enhancement of natural infrastructure such as coastal wetlands can help build resiliency to climate change.
Stormwater Compliance
Our firm’s thorough understanding of permit requirements, and the science behind them gives us unique insights into the challenges and opportunities of an effective stormwater program.
Watershed Management and Nutrient Control Plans
Watershed-based plans are critical to understanding key watershed issues and developing effective implementation strategies, including prioritized restoration actions.
Municipal Code Audits and Stormwater Regulations
Our staff not only help communities meet their permit requirements but explore meaningful code changes to enhance climate resiliency, social equity, and quality of life specific to their town or city.
Education and Training
HW has written technical guidance manuals and conducted extensive trainings on low impact development strategies, erosion and sediment control, GSI designs, watershed planning, retrofitting, emergency response, advanced zoning techniques, and climate change preparation.
