Background and Analysis:
In early 2017, the City, the Port and LOTT entered into an Interlocal Agreement to jointly fund and participate in a formal sea level rise planning process for downtown Olympia and the Port peninsula.

The tasks to be completed by AECOM and the City, Port and LOTT for this project include:
* Evaluate the best available science regarding potential sea rise (Complete).
* Develop a sea level rise planning framework incorporating community input (Complete).

As a component of this task, conceptual drawings for three physical adaptation strategies (Capitol Lake, Percival Landing and Billy Frank Jr. Trail) will be developed. Additional analysis of LOTT and Port specific needs will be provided. (Dr...
