The Harmony Park Designation Act of 2026 aims to officially designate the triangle park located in Reservation 160 as "Harmony Park." This designation is made pursuant to the Street and Alley Closing and Acquisition Procedures Act of 1982. The act outlines the process for its applicability, which will take effect once the fiscal impact is included in an approved budget and financial plan. The Chief Financial Officer is responsible for certifying this inclusion and notifying the Budget Director, who will then publish the notice in the District of Columbia Register.

Additionally, the act includes a fiscal impact statement that has been adopted from the committee report, fulfilling the requirements of the General Legislative Procedures Act of 1975. The act will become effective following the Mayor's approval, a 30-day congressional review period, and publication in the District of Columbia Register.
