About 2dot


HORSEPOWER! It’s how we keep up. Our staff has over a century of combined experience in environmental compliance and engineering. We integrate homegrown knowledge of local, state, and federal regulations with economics and science to maintain the equilibrium of our natural resources.

What We Do

The numbers don’t lie. We reduce our overhead cost by hiring and retaining our cross-trained and certified staff to work in many disciplines. In one field visit, using one truck, we can complete a wetland delineation, stormwater inspection, spray herbicides/pesticides, or conduct a raptor survey. This allows better use of our staff, your budget, and increased efficiency. That’s Horsepower!
