At the northern shore of Willapa Bay in southwest Washington lies the community of North Cove. Currently, there is a battle going on between the residents of North Cove and the erosion that threatens their homes. These satellite images below illustrate the degree of loss that has already taken place. A Google Earth time lapse of North Cove between 1984 and 2016 can also be seen at this link.
While this is a significant loss, the erosion continues to threaten the community. An additional 499 parcels totaling 547 acres are projected to erode by 2060. The areas at risk of erosion and their projected erosion date can be seen in the image below.
Up to this point, most of the parcels lost have been undeveloped land, with a total of 60 residential properties falling into the ocean, 33 of which were single-family residences. Looking ahead, the number of residential properties expected to erode totals 280, of which 213 are single-family residences.
The estimated future economic impact is $25.1 million to $34.8 million, with an estimated average of $30 million.
Most of the loss is expected to occur between 2030 and 2050, meaning that there is still time to prevent the largest losses if mitigation steps are taken soon.
Evaluation of the situation is ongoing, and this study provides an important piece of information to inform the process. It is important to identify the value of what’s at risk to justify the costs of any mitigation efforts. Representatives Brian Blake has sponsored a “Local Community Project” (LCP) to be funded in this upcoming state biennium budget, which would provide a down payment on proposed next steps towards permanent protection measures. As it stands, the future of the North Cove community is still uncertain.
