Hello,

Is there a year before which a building can be consider historic for USGBC?

Okay, I'll start this off by stating the requirement, and then asking a (simple) question. LEED v4 requirement: Locate on a brownfield where "soil or groundwater contamination has been identified"

In Germany the (property) owner has to arrange inquiries regarding the soil pollution and burden by weapons, explosive ordnance and combat equipment (military hazardous waste).

A campus project I am working on is located on a site where some agricultural contaminants were discovered in the soil.

can anyone explain historic district? i don't exactly know what that is

Does a project still qualify for credit if the site is within a DDA boundary that is set to change in the upcoming months?

Can this credit be achieved if the remediation occurred outside of the LEED project scope? My understanding is that this was not allowed for the Brownfield Redevelopment credit under LEED v3.

The project conducted a Phase I ESA and concluded that there maybe potential for chemical vapor intrusion to indoor air from off-gassing associated with the groundwater plume, therefore a phase II

Is option 1 viable if you demolish a non-listed building in a historic district and build a new one in its Place?
