We evaluate ecological effects caused by human activities such as draining of wetlands or release of chemicals. The term “stressor” is used to describe any chemical, physical, or biological entity that can induce adverse effects on individuals, populations, communities, or ecosystems. These assessments follow the National Environmental Policy Act (NEPA) assessment standards, which include environmental consideration into Federal agency planning and action. This is done by providing decision makers and other stakeholders with the information they need to understand potential environmental impacts of proposed actions. One of the basic principles of NEPA is that people make better decisions when they have clear information about the consequences and trade-offs associated with taking any given course of action. Preliminary assessments are used to evaluate if there is a potential to have an adverse effect by proposed construction or redevelopment of a property.
A NEPA checklist addresses the regulation, 47 CFR ß1.1307 (A) 1-8 and ß1.1307 (B) and covers the following:
Wildlife Refugees and Wilderness Areas
Endangered Species and Critical Habitat
National Registry of Historical Significance
Indian Religious Sites
FCC and FAA Sites.

Phase I Environmental Site Assessments (ESAs)
A Phase I Environmental Site Assessment is conducted on real estate or commercial parcels to determine it’s potential for contamination by hazardous substances. An ESA will allow a buyer or lender to make an informed decision as to the potential environmental risks associated with the purchase of a property. Residential properties generally will not need a Phase I ESA, unless there are special conditions, such as an underground or above ground storage tank or a known spill on the property. Residential properties may also need an ESA if they are adjacent to a property with a known or suspected environmental condition.
DRH can also include limited surveys for ACM, LBP, mold or water damage, lead in water sampling, radon testing, and ecological surveys.
DRH follows the Standard Practice for Environmental Assessments; Phase I Environmental Assessment Process. ASTM E1527-13
