SECTION 106 PROCESS- 10/07/15: Initiated consultation with the DC SHPO via letter

- GSA determined that the undertaking had the potential to affect historic resources

in the Lafayette Square National Historic Landmark District and invited DC SHPO

to review and consult to seek ways to avoid or minimize effects upon the resources

this district contains, in accordance with the Advisory Council’s Procedures for the

Protection of Historic Properties, 36 CFR Part 800.3 (a), (c, 3) and 800.5 (a).

- NPS, ACHP and NCP were notified by copy of this letter with an invitation to

participate in the consultation

- 10/21/15: Preliminary site walk conducted with Consulting Parties. CPs present

included GSA, DC SHPO, NPS, CFA, NCPC and ACHP.

- 10/23/17: 2nd Consulting Party meeting held (Office of EOP and USSS also

participated)

- 01/29/20: 3rd Consulting Party meeting held (WHHA included in CPs)

- 03/04/20: 4th Consulting Party meeting held

- 03/20/20: Received letter from ACHP notifying of decision not to participate in

consultation stating - Based upon the information provided, we have concluded that

Appendix A, Criteria for Council Involvement in Reviewing Individual Section 106

Cases, of our regulations, “Protection of Historic Properties” (36 CFR Part 800), does

not apply to this undertaking. Accordingly, we do not believe that our participation in

the consultation to resolve adverse effects is needed.”
