The Office of District Waterways Management Establishment Temporary Amendment Act of 2025 aims to modify the existing Office of District Waterways Management Establishment Act of 2022. Key changes include aligning the Mayoral appointment process for the District Waterways Advisory Commission with similar commissions, adding the Department of Parks and Recreation as a non-voting ex-officio member, and adjusting the meeting schedule to allow for better stakeholder engagement. Additionally, the bill grants the Commission the authority to determine when the Advisory Plan needs updating, extending the update period to at least every three years.

Specific amendments include changing the frequency of Commission meetings from once a month to once every two months, and altering the timeline for developing the Advisory Plan from one year to two years. The bill also modifies the process for adopting the Advisory Plan, requiring it to be submitted for publication within 60 days after public comments are concluded. Furthermore, it makes conforming amendments to the Confirmation Act of 1978 to reflect these changes. The act will take effect following approval by the Mayor and a 30-day congressional review period, and it is set to expire after 225 days.
