Our Commitment to Sustainability

As it turns out, when you change the earth for a living like we do, you have the opportunity to design with the earth in mind.

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 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 believe in the power of engineering the earth to help make the world a better place.

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

Our environmental stewardship begins at home with our everyday corporate operations. Refillable water bottle stations, office-wide recycling, and similar sustainable practices help us ensure that every day we are making sustainable choices.

In reality, Timmons Group’s sustainability footprint is much larger than just our office spaces. With projects like multi-sport complexes and roadway interchanges, our impact on the world is much more than just what happens in our office. As it turns out, when you change the earth for a living like we do, you have the opportunity to design with the earth in mind.

Timmons Group is proud to offer services to our clients so they can make informed decisions to minimize impacts of development. Our staff in civil engineering, technology, and landscape architecture are experts in their fields. 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 engineering needs.

At Timmons Group, we are changing the how the world is perceived through sustainability. Engineer the earth with us.
