Full Breakdown

Port Townsend requires approval under PTMC 16.08 before any construction or development occurs within a mapped special flood hazard area (SFHA). If no other city permit applies, the planning and community development department issues a standalone floodplain development permit processed as a Type I-A land development permit. If another permit already covers the work, the floodplain approval is folded into that permit instead. Projects proven to sit entirely outside the SFHA, per FEMA's flood insurance rate maps or an approved letter of map change, are exempt.

Violations & Fines

The planning director enforces PTMC 16.08 violations under the general code-enforcement provisions of Chapter 1.20 PTMC, covering unpermitted or noncompliant SFHA construction.
