Environmental Site Assessment

The purpose of the Phase I ESA is to identify, to the extent feasible, recognized environmental conditions (RECs) in connection with the property. This assessment includes a site reconnaissance as well as research and interviews with representatives of the public, property management, and regulatory agencies.  We perform all Phase I ESAs in general accordance with the current American Society for Testing and Materials (ASTM) standard E 1527 and the All Appropriate Inquiries (AAI) final rule.

Tower Construction

Phase I ESAs are provided for telecommunications site locations based on the need for ground impact to connect utilities, excavate for foundations, and provide spaces for the placement of equipment. Phase I ESAs are the due diligence required to ensure that telecommunications carriers are responsible in their site selection and in ensuring appropriate health and safety practices are enforced.

Agriculture and Open Space

Open space and agricultural properties present many of their own challenges. Historical agricultural use, ranching operations, and general farming uses are considerations in evaluating the environmental “health” of a property. Farm buildings and homes may present additional considerations including lead paint and other hazards. We have completed many projects for non-profits taking on new open space and agricultural businesses looking to expand.


Commercial ESAs provide evidence of due diligence in determining potential environmental concerns from activities that have previously been, or currently are, being conducted on a property. These ESAs are commonly requested by lenders in property acquisitions to demonstrate due diligence in completing the transaction.
