Our Commitment

We’re committed to responsible protection and modification of our earth. As engineers and designers, we’ve built environmental stewardship into the work we do every day shaping the face of the Earth. At Timmons Group, we are changing the how the world is perceived through sustainability.

Environmental stewardship is not a trend at Timmons Group — it defines who we are as a company 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 like multi-sport complexes, airports and roadways, and warehouse design, our impact on the world is much more than what happens behind our office doors.

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.
