Environmental Desktop Review

(with Historical Research and Risk Evaluation)

The Environmental Desktop Review with Historical Document Search (Desktop Review) process identifies potential or existing environmental contamination liabilities to a limited extent.

The Desktop Review includes obtaining and reviewing available State and Federal environmental databases, for the subject property and nearby surrounding areas. The RDR includes information on sites of known contamination and/or environmental activities which have been reported to State and Federal agencies. The Desktop Review also includes a Review of Historical Documents, such as Aerial Photographs, Historical Topographic Maps, Fire Insurance Maps, and City Directories (as available).

Enviro Assessment, PC will provide a summary letter on the results of the database search, and whether the subject property and/or nearby or adjacent properties are identified. Desktop Reviews are typically ordered on vacant land, agricultural land (without major farming operation structures), office condos, and even for residential housing for both new loans and refinancing.

Please note, this is not a Phase I Environmental Site Assessment and does not conform to the ASTM standard or the EPA AIA rule for due diligence.  Therefore, you may not be fully protected by the law with this type of Report.

Enviro Assessment, PC will conduct a review of the Physical Source Settings as defined in the ASTM Standard E1527-13 in Section 8.2.4 and Historical Use Information as defined in the ASTM Standard E1527-13 Section 8.3.

The historical search includes reviewing documents for past uses of the Subject Property. The documents Enviro Assessment, PC reviews include the following sources (as available):

  • Aerial Photographs
  • Fire Insurance Maps
  • City Street Directory
  • USGS Current and Historical Topographic Maps
