Our Commitment

At Timmons Group, environmental stewardship is part of the work we do every day. As engineers and designers, we shape the physical environment around us. We believe that responsible practice means minimizing harm to our natural resources, employing best design practices, and offering services that directly benefit vulnerable communities and make them resilient to the impacts of climate change.

Environmental stewardship is not a trend at Timmons Group — it defines who we are as a firm and as individuals.

Timmons Group is committed to changing the application of sustainability in civil engineering, landscape architecture, and technology one project at a time. From rain gardens that filter runoff water to applications that track wildfire progression, we’re re-envisioning the world around us to make it a better place to live.

Timmons Group’s environmental stewardship begins at home with our corporate operations, but our sustainability footprint is larger than us. With projects that support roadways, parks and recreation, medical facilities, and schools, our impact on the world is much more than what happens behind our office doors—it is the difference our projects make in the world around us.

That’s why Timmons Group is proud to offer services to our clients so they can make informed decisions to minimize a project’s environmental footprint. With over 20 years of LEED certified sustainability practices, Timmons Group is keen on providing you with the best and most ethically designed answers to your project needs. Engineer the earth with us.
