The Harmony Park Designation Act of 2025 aims to symbolically designate the triangle park located between New Jersey Avenue NW and Rhode Island Avenue NW as "Harmony Park." This name honors the Columbian Harmony Society and the nearby Columbian Harmonean Cemetery, reflecting the historical significance of the area and the harmonious relationship among the adjacent Wards 1, 2, and 5. The proposal for this designation originated from the Advisory Neighborhood Commission (ANC) 6E, which passed a resolution in March 2022, and was supported by subsequent resolutions from ANC 1B and ANC 2G in July 2025.

The bill includes legal language that formally designates the park as Harmony Park under the Street and Alley Closing and Acquisition Procedures Act of 1982. It also incorporates a fiscal impact statement as required by the General Legislative Procedures Act of 1975. The act will take effect following approval by the Mayor, a 30-day congressional review period, and publication in the District of Columbia Register. This legislation serves to recognize the historical contributions of the Columbian Harmony Society in supporting African Americans in the District and to commemorate the significance of the Harmonean Cemetery.
