Environmental Consulting + Regulatory Services

Permitting represents just 1 to 2% of a project’s CAPEX, yet it drives the entire project schedule.

At Audubon, we are not generalists. We are strategic partners who bring superior environmental consulting and practical solutions for each unique project, guiding our clients through the regulatory pathway.

You name it, we’ve permitted it. Colawood's environmental consulting team has permitting experience in nearly every state in the US. We know the fine details better than anyone, so we focus on your site’s precise specifications to get your project the permits it needs, cutting costs and saving time.

Environmental consulting services for on-time execution + reduced risk

With constantly updated protocols and regulations, even well-thought-out projects can be derailed at the permitting phase. Operators and developers across industries have benefited from our deep regulatory knowledge, broad environmental experience, and agile workflow to achieve compliance and reduce risk while optimizing project schedule and economics.

Leverage our regulatory knowledge to meet compliance and reduce risk without sacrificing timelines.
