The Environmental Planning Group (EPG) is highly aware of plants, animals, and their habitat throughout the state.
Each highway project is meticulously evaluated for impacts to plants and animals, including species classified as Threatened and Endangered by the US Fish and Wildlife Service, and various species listed by resource agencies and tribes.
The primary documents used to evaluate wildlife include:
- Biological Evaluations
- Biological Assessment and Evaluations
Also specific biological studies are conducted for highway projects on tribal lands.
To help preserve the integrity of native vegetation throughout the state, the EPG evaluates projects for invasive weeds, and prescribes mitigation measures to remove and prevent introduction of such species. In addition, EPG evaluates projects for impacts to protected native plants per the Arizona Native Plant Law.
