This report outlines county-level flood-risk data and housing statistics for Washington State in light of this month\u2019s devastating flooding. Our hearts go out to Washington residents during this challenging time.<\/i><\/strong><\/p>\n

Torrential rainfall that began last week has caused many of Washington State\u2019s rivers to overflow, flooding scores of homes and triggering power outages and mudslides across the state. Over <\/span>100,000<\/span><\/a> people have been advised to evacuate, and Washington Gov. Bob Ferguson has declared a state of <\/span>emergency<\/span><\/a>. More flooding is <\/span>expected<\/span><\/a> this week as one major river levee failed<\/a> on Monday and a second<\/a> failed on Tuesday. Blizzards and high winds are also in the forecast<\/a>.<\/span><\/p>\n

Many of Washington\u2019s 39 counties have either experienced flooding or faced some form of flood warning. <\/span>Skagit County<\/span><\/a> and <\/span>Snohomish County<\/span><\/a>, both located north of Seattle, have been hit especially hard.\u00a0<\/span><\/p>\n

In Skagit County, 22,810 homes\u2014or 28.6%\u2014face high flood risk, according to a Redfin analysis of <\/span>First Street<\/span><\/a> data pulled prior to the flooding. That\u2019s the fourth-highest number among the 39 counties in Washington State and the second-highest share. Skagit County has a population of around 130,000.\u00a0<\/span><\/p>\n

In Snohomish County, 23,215 homes face high flood risk, the third highest number among the counties in Washington State. That represents 7.6% of homes in Snohomish County, which has a population of about 900,000. This analysis focuses on homes with <\/span>high<\/span><\/i> flood risk, but it\u2019s worth noting that other homes face risk as well.<\/span><\/p>\n

\u201cI\u2019ve had a home closing pushed back, showings delayed, and listing appointments rescheduled because of flooding and road closures,\u201d said <\/span>Don Bleha<\/span><\/a>, a Redfin real estate agent in Snohomish County. \u201cThe buyer whose closing got delayed visited the home and the yard was all water. Now he can\u2019t even get there because the highway is closed due to fallen trees and mudslides. People who have considered buying a place in the mountains may be more cautious moving forward\u2014especially those who don\u2019t fully understand how seasonal flooding works in these areas.\u201d<\/span><\/p>\n

Bleha, who lives on the Skykomish River outside the town of <\/span>Index<\/span><\/a>, said his yard is flooded and his internet service was out most of last week.<\/span><\/p>\n

The counties in Washington State with the largest share of homes facing high flood risk according to First Street are Wahkiakum County (35.9%), Skagit County (28.6%), Grays Harbor County (26.2%), Pend Oreille County (25.6%) and Lewis County (22.5%). <\/span>Many<\/span><\/a> of these counties have <\/span>grappled with<\/span><\/a> flooding over the past week.\u00a0<\/span><\/p>\n

Four of Washington\u2019s 39 counties are considered high-flood-risk counties on a national scale. Redfin defines a high-risk county as one that ranks in the top 10% in the U.S. when it comes to the share of homes facing high flood risk. The counties in Washington State that meet this definition are Wahkiakum County, Skagit County, Grays Harbor County and Pend Oreille County.<\/span><\/p>\n

The counties in Washington State with the largest <\/span>number<\/span><\/i> of homes facing high flood risk are King County (41,928), Pierce County (33,097), Snohomish County (23,215), Skagit County (22,810) and Grays Harbor County (15,773), which have all been in the news due to flooding over the past week. Many counties in Oregon have been under flood warnings as well.<\/span><\/p>\n
