Phase I Environmental Site Assessment

Our Phase I Environmental Site Assessments are completed by experienced staff and all are directed by environmental professionals with a minimum of 10-years experience. Our projects are cost effective because we are a mid-size employee owned company and we do not have the large overhead and expenses of a large company. We have the available staff and experience to complete multi-site portfolios nationwide with very short due dates. We take pride in the fact that we can provide quality Phase I ESA reports for less cost than our competition.

RSB Environmental is the national leader in Phase I Environmental Site Assessments by volume. All our reports are completed to meet the standards of ASTM E1527-13. RSB Environmental often customizes reports to meet individual client or agency lender’s (Fannie Mae, Freddie Mac) requirements while taking the widely varying geology and topography of  the region into consideration.
