Open House Event for Environmentally Critical Areas

Seattle has five environmentally critical areas such as wetlands and wildlife habitat areas. How do we protect these environmentally critical areas (ECAs)? DPD is hosting an open house event for the update to our ECA regulations on Wednesday, February 25, 5:30-7:00pm in the Bertha Knight Landes Room at City Hall.

The presentation will explain what and where environmentally critical areas are, how we incorporate Best Available Science, and how the ECA regulations protect critical areas. Learn about the Growth Management Act and how it influences updates and changes to ECA regulations. This event will help guide the effectiveness of our ECA policies and regulations.

In Seattle, environmentally critical areas include the following: wetlands, fish and wildlife habitat conservation areas, geologic hazard areas, flood-prone areas, and abandoned landfills.
