In addition to a Phase I ESA, the developer clients of CTL are more commonly requesting Biological Evaluations as part of their environmental due diligence.  A Biological Evaluation is particularly recommended in areas that have not seen development, and in some jurisdictions it is actually a requirement.   A Biological Evaluation includes a site visit by a trained biologist to determine what threatened or endangered species could potentially be impacted within the given habitat.  Examples include the burrowing owl, a state species of concern which uses prairie dog burrows, and requires further study and audible bird calls to determine their presence or absence.  Our Biological Evaluation also includes a determination whether wetlands could be impacted by development.  If a wetland is regulated, or “jurisdictional” as its referred to by the U.S. Army Corps of Engineers, CTL has the ability to delineate the exact acreage to be disturbed, if any.  If needed, we can then assist with permitting under Section 404 of the Clean Water Act.
