LEED BD+C: Schools | v2 - Schools 2007

Environmental site assessment

SSp2 | Required


Ensure that the site is assessed for environmental contamination and if contaminated, that the environmental contamination has been remediated to protect children’s health.


Conduct a Phase I Environmental Site Assessment (as described in ASTM E1527-05) to determine if environmental contamination exists at the site. If contamination is suspected conduct a Phase II Environmental Site Assessment (as described in ASTM E1903-97 (2002)).


Sites that are contaminated due to the past existence of a landfill on the site are prohibited. If the site is otherwise contaminated, then it must be remediated to meet local, state, or federal EPA region residential (unrestricted) standards whichever is most stringent. Documentation from the authority must be provided (such as EPA’s “Ready for Reuse” document) to prove “safe” levels of contamination have been achieved. As the remediation process leads to significant environmental benefit, one point (in SS credit 3) will be given for successful documented remediation of the site.
