The Parkside Support Amendment Act of 2025 aims to amend the Tree Canopy Protection Amendment Act of 2016 by exempting certain heritage tree requirements for the Parkside mixed-use economic development project, specifically for properties where the Zoning Commission approved a stage-one planned unit development prior to the Act's effective date. Additionally, the bill seeks to amend section 47-4658 of the District of Columbia Official Code to authorize real property tax abatements for Parkside Parcel 9A and 9B, allowing for an annual tax abatement of up to $300,000 per parcel for 30 years, contingent upon the issuance of a final certificate of occupancy by September 30, 2029.

The bill includes specific provisions for the tax abatement, stating that it will apply to Lots 865, 866, 867, 868, and 869 in Square 5056, as well as to Parcel 9A and Parcel 9B, which are defined within the legislation. The tax abatements and exemptions from related fees are designed to encourage development in the Parkside area and are in addition to any other tax relief available. The act will take effect following the Mayor's approval and a congressional review period.
