Average high tides are creeping higher in Puget Sound

Between 2016 and 2021, $21 million provided by the Environmental Protection Agency (EPA) funded 100 different projects to protect, restore, and study critical habitats in Puget Sound. This publication presents an overview of many of the key accomplishments and lessons learned from these efforts. It is a catalog of some of the ‘big ideas’ presented by the scientists and conservationists involved, and it is meant to inform and guide future Puget Sound recovery efforts. This overview is based on the full synthesis report, “Synthesis of Habitat Strategic Initiative Lead 1.0 2016-2023 Investments for Puget Sound Recovery," published by the Puget Sound Institute.

All across the region, communities are finding that rising seas and rising rivers are two sides of the same coin. New research funded by the Environmental Protection Agency may help managers target their responses to climate-fueled flood risks in Puget Sound. The following article was commissioned by the Habitat Strategic Initiative Lead (HSIL), a cross-agency team co-led by the Washington Departments of Fish and Wildlife and Natural Resources.

本區域各地的社區發現，海平面上升和河水上漲是一體兩面的問題。氣候變遷使得Puget 海灣面臨愈來愈高的洪水風險，環境保護局贊助的新研究可能有助於主管機關找出因應之道。

Trên toàn khu vực, các cộng đồng đang nhận thấy rằng tình trạng mực nước biển và mực nước sông dâng lên có mối liên hệ chặt chẽ. Nghiên cứu mới do Environmental Protection Agency (Cơ Quan Bảo Vệ Môi Sinh) tài trợ có thể giúp các nhà quản lý hướng các biện pháp ứng phó của họ vào các rủi ro lũ lụt do khí hậu tại Puget Sound.

En toda la región, las comunidades están descubriendo que el aumento del nivel del mar y los ríos son dos caras de la misma moneda. Una nueva investigación financiada por la Agencia de Protección Ambiental puede ayudar a los administradores a enfocar sus respuestas a los riesgos de inundaciones provocadas por el clima en el estrecho de Puget.

A pilot project to create a 'living dike' in Canada's Boundary Bay is designed to help a saltwater marsh survive rising waters due to climate change.

Close to 30% of Puget Sound's shoreline is armored with seawalls and other structures meant to protect beaches against rising tides and erosion. But science increasingly shows that these structures are ineffective and cause significant harm to salmon and other creatures. State and federal agencies have been encouraging private property owners to remove armoring in a race to improve habitat, but why did so much of it start appearing in the first place?

The 2018 Shoreline Armoring Implementation Strategy identified development of new financial incentives as a near-term priority. This study, funded by the Habitat Strategic Initiative, assesses the feasibility of developing a Shore Friendly residential shoreline loan program.

Can scientists bring back the lost tidal forests of Puget Sound? It could take generations, but restoring this rare habitat will pay big dividends for Puget Sound’s salmon.   

A report from the Washington Coastal Resilience Project provides an updated assessment of projected sea level change for coastal Washington State and its relationship to coastal hazards such as flooding and erosion. 

The Puget Sound Coastal Storm Modeling System analyzes the potential impacts of sea level rise on nearshore areas of the Puget Sound region. 

Climate change could cause sea levels to rise more than four feet in some parts of Puget Sound, leaving shoreline residents with some tough decisions. Experts say fighting the waves with conventional seawalls may not be the answer.

Planning for rising seawater in Puget Sound has often focused on public property such as roads, buildings and utilities. Now local governments are looking more closely at private property despite regulations based on traditional flooding history.

Where shoreline bulkheads remain in place, the loss of spawning habitat used by surf smelt is likely to reach 80 percent.

Rising sea levels are expected to exacerbate habitat loss caused by bulkheads, according to studies in the San Juan Islands.

A 2015 report from the University of Washington provides the most comprehensive assessment to date of the expected impacts of climate change on the Puget Sound region.
