Stone Wharf Improvements

The Town of Chebeague Island selected Weston & Sampson to provide flood modeling and infrastructure design services in response to flooding concerns at the Stone Wharf.

The Stone Wharf is critical to island life, supporting ferry service, commercial fishing, freight delivery, and recreational & transient boating. Recent king tides and coastal storm events have caused flooding, impacting public use and access to the facility.

Weston & Sampson’s comprehensive approach to this project included the incorporation of climate change mitigation and adaptation into infrastructure design, aiming to achieve near- and long-term resiliency and support all current uses. We integrated sea level rise projections consistent with assessments being carried out through the state to:
• Model flood scenarios under various conditions, including with and without projected sea level rise and storm surge for up to a 50-year planning horizon (2070).
• Recommend design flood elevations that account for both present-day coastal conditions and future sea level rise scenarios.
• Propose strategies to revise previously proposed plans for the preservation and continued use of the existing Stone Wharf to reduce vulnerability to current and future coastal flooding.
