Requirements
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). Projects outside the U.S. may use a local equivalent to ASTM E1527‐05 Phase I Environmental Site Assessment and ASTM E 1903‐97 Phase II Environmental Site Assessment.
AND
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 the 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, Brownfield Redevelopment) will be given for successful documented remediation of the site.

Cost estimates for this credit
On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.
Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.
This information is also available in a full PDF download in The Cost of LEED v4 report.

Can the environmental site assessment and brownfield remediation efforts conducted for a prior LEED project (for the purposes of LEED for Schools and LEED for Healthcare certification) be acceptable to achieve compliance for a new LEED project, which is located on a portion of the same site?
A goal of SSp2: Environmental Site Assessment and SSc3: Brownfield Redevelopment is to ensure that the site is assessed for contamination and, if present, the contamination has been remediated to protect occupant health. If a School or Healthcare project is located on a site that has already been completely assessed and remediated using a Phase I ESA, Phase II ESA, or local equivalent, then the project may use the results of that assessment and remediation to earn SSp2 and SSc3, Option 1. In order for new projects to use prior remediation efforts to qualify for SSp2/SSc3, the following must be provided:1. results of the Phase I ESA (ASTM E1527-05);2. if environmental contamination is suspected, results of the Phase II ESA (ASTM E1903-97 (2002);3. a letter from the environmental consultant or applicable regulatory agency stating that remediation has been achieved at the site to meet residential (unrestricted) use ; and4. a document describing site contamination assessment and remediation strategies in detail. If the assessment and remediation strategies were conducted per superseded Phase I and Phase II ESA standards, describe how they are equivalent to ASTM E1527-05 and ASTM E1903-97 (2002). Internationally applicable.
Can ASTM E1527-13 be substituted for ASTM E1527-05?
For SS Prerequisite Environmental Site Assessment, projects may use ASTM E1527-13 (or local equivalent) in place of ASTM E1527-05.
