Community & Environment


We recognize that we have a unique responsibility to the environment and the communities in which we operate. In many ways, our use of the land may be considered an interim land use. As such, our activities must appreciate and contemplate the ultimate land use. To this end we employ a full time staff of environmental, regulatory, and land use specialists. Working with community leaders we strive to be an asset and partner to the communities in which we operate.

We are extremely proud of our reputation as a community steward. We have received national, state and local recognition for our environmental commitment and support of the communities in which we operate.
