Little Pompey Wetland Restoration

In 2008, PBS was selected to support the City of Cannon Beach’s Coastal Coho Endangered Species Act (ESA) Response Plan, specifying actions to be taken by the City which would assist in the recovery of Oregon Coast Coho salmon in the Ecola Creek Watershed.

A goal of the ESA Plan was to optimize and restore the hydrological connection of the Little Pompey Wetlands and adjacent Ecola Creek estuary, in order to reestablish these areas as salmon habitat, while continuing to protect the adjacent downtown areas from flooding. PBS developed potential restoration alternatives which involved converting existing tidegates to a fish-friendly system and converting a wastewater treatment lagoon into an estuarine wetland.

The selected alternative was then refined based on comments from City officials as well as resource agency staff. PBS coordinated with the Oregon Department of Environmental Quality (ODEQ) on a management plan to convert the northwest treatment lagoon to estuarine wetland. PBS geotechnical engineers also evaluated the stability of the dikes surrounding the northwest lagoon. Staff coordinated with a City-hired grant writer and assisted with permitting, design documents for restoration, negotiations, additional natural resources fieldwork, and support.
