Environmental Due Diligence
Due Diligence Offerings from Creekside
Transaction Screen Reports are a fast and inexpensive method to research the land use history and environmental status of your property and surrounding sites. The transaction screen includes a search of federal, state and local environmental databases, completion of a questionnaire by a person knowledgeable of the site, owner and/or occupant interviews, fire department interviews and/or Sanborn map reviews, and a site inspection by one of our environmental professionals. Our reports meet or exceed the American Society of Testing and Materials (ASTM) E-1528-06 standard for Transaction Screens.
The Transaction Screen is a standardized approach to environmental due diligence that provides a basic understanding of the environmental condition of the property. This level of assessment is only recommended for low impact sites such as undeveloped rural or residential properties. If the driving force behind the environmental due diligence is a desire to qualify for one of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Landowner Liability Protections (LLPs), a transaction screen should not be used. Instead, the ASTM Practice E 1527-05 for Environmental Site Assessments: Phase 1 Environmental Site Assessment (Phase 1 ESA) Process should be used. Please contact our Portland, Oregon Environmental Consultants if you are unsure about your due diligence obligations.
