In some cases, problems were discovered after a site had been acquired. How do I know whether we have performed enough site investigation studies (hazmat, historical, archaeological, etc.)?
The best way is to talk to the appropriate people (GSA Central Office, consultants, SHPO, local community, etc.) and fully engage them in the process. Make sure that issues from the criteria checklists have been considered fully. Follow through on NEPA and other required studies. Maintain open lines of communications, follow local news stories, ask lots of questions, and maintain an interest in local issues. Don’t rely solely on information provided by brokers or owners. If you learn something questionable, then follow through until you’re satisfied with the answers. Discussions of “lessons learned” with colleagues in other Regions and in the GSA Central Office also can help avoid pitfalls.
