21 Mar
Summary
- Committee proposes infrastructure upgrades to combat Machias flooding.
- Recommendations address stormwater, wastewater, and bridge replacement.
- Plan aims to protect downtown businesses and Route 1.

The Upper Machias Bay Master Plan Leadership Committee has finalized recommendations to address chronic flooding in downtown Machias. These proposals focus on critical infrastructure upgrades, including stormwater management, wastewater treatment, and the replacement of the Machias Dike Bridge.
The committee suggests immediate actions like repairing drainage on Short and Court Streets and incentivizing landowners for green infrastructure. Longer-term solutions involve comprehensive engineering studies for stormwater system enhancements and securing funds for flood-risk reduction projects.
Public input emphasized hybrid solutions combining water management, barriers, and active control, recognizing the layered causes of flooding. The recommendations also cover public engagement, landfill management, and bolstering emergency response plans.
Key goals include keeping Route 1 open, safeguarding downtown businesses, and improving emergency preparedness. The committee also recommended an in-kind replacement for the aging Machias Dike Bridge, which carries Route 1 and utilities over the Middle River.
