The Parkside Support Amendment Act of 2025 aims to amend the Tree Canopy Protection Amendment Act of 2016 by providing an exemption from heritage tree requirements for specific lots within the Parkside mixed-use economic development project, which received stage-one planned unit development approval from the Zoning Commission 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 Parcel 9B, allowing for annual tax abatements of up to $300,000 per year for 30 years, contingent upon the issuance of final certificates of occupancy by September 30, 2029.

The bill includes specific provisions for the tax abatement process, stating that if the final certificate of occupancy is issued on or before the deadline, any related fees or deposits paid by the property owner will be refunded or forgiven. The tax abatements and fee exemptions are designed to be in addition to any other tax relief or assistance applicable to the development of the specified lots and parcels. The act will take effect following the Mayor's approval, a congressional review period, and publication in the District of Columbia Register.
