  • Welcome to the Current!
    Welcome to the Current! Well, here comes Fall! Summer is slowing down and the cooler air is coming in. Leaves are starting to change here and there....and the rain is back. Make sure you come and check out the Park during this cool, sometimes wet season - it is a great place to visit rain or shine! This month in the Current learn about the bridge painting project happening now, a recap of our summer programs and some more history of the Park! Across the bridge by Elle Tracy Photo by Cindy Elliser Beginning in August, 2019, the Washington State Department of Transportation began a two-year project to restore and repaint the Deception Pass bridge – the only link for Whidbey Island residents on an off the island, unless, of course, you have a jet at your disposal. The existing paint work was completed more than 20 years ago, and with salt, wind and wear, the corrosion repair and paint work is necessary to support the resident and tourist traffic, estimated to be about 20,000 vehicles daily. Then there’s the foot traffic…. The temporary metal poles you see rising from the exterior barriers, support containment tarps under the bridge that prevent repair debris from dropping into the water. Containment tarps, photo by Cindy Elliser The project will shut down in the late fall for the winter, to begin again in the spring of 2020. Completion of the work is scheduled for fall of 2020. During work periods, you’ll hear unusual noise during the day, and quieter work noise overnight, when the bridge span is reduced to one lane of traffic.

  • Natural Hazards on Whidbey Island
    Natural Hazards on Whidbey Island Protect and prepare your family and your home — a guide for surviving disasters caused by earthquakes, landslides, wildland fires, tsunamis, and windstorms Island County, Washington Department of Emergency Management Digital elevation map of Island County (Jessica Larson) ii Dealing with Natural Hazards on Whidbey Island This is a guide to the natural hazards that could affect you, your family, and your property. It offers a brief description of the ways you can prepare your home and family to survive disasters caused by earthquakes, landslides, wildland fires, tsunamis, and windstorms. Power outages caused by windstorms during the winter of 2006-2007 — as well as numerous other events in prior and more recent years — have made most residents of Whidbey Island amply aware of the difficulties of being without light, heat, water, and the ability to prepare meals or use health-related equipment. Although most of us have experienced being without power for less than a week, we have still been able to travel to a grocery, a hospital, or the mainland. Friends across the island could help each other. But what if there were a major natural disaster that cut off the island from the mainland and we were entirely on our own for two or three weeks? A truly large storm or an earthquake could destroy or damage docks at the Clinton and Coupeville ferries systems and seriously compromise footings of the Deception Pass bridge, disrupting delivery of food, water, fuel, emergency services, and many other vitally necessary elements of our Island life. These realities are even more evident recently as we have had record rains, experienced more landslides, and observed the damage suffered by the islands of New Zealand and Japan.

  • Draft in Progress
    ISLAND COUNTY PARKS AND HABITAT CONSERVATION PLAN Planning Context Summary Memo June 2010 Prepared by: MIG, Inc. 815 SW 2nd Avenue, Suite 200 Portland, Oregon 97204 503.297.1005 www.migcom.com PLANNING CONTEXT 1. Introduction In Spring 2010, Island County and the Whidbey Camano Land Trust (WCLT) formed a collaborative partnership to develop a Parks and Habitat Conservation Plan for the County. The planning process creates a unique opportunity to systematically address declining funding resources that have made it difficult for the County to provide and care for parks and natural resources on Whidbey and Camano Islands. The plan will focus on the role that Island County plays in managing and protecting parks and habitat areas, since West Beach Park many other jurisdictions also provide natural and recreational resources throughout the County. The Plan will provide strategies and directions to make the best use of existing resources and work with other providers as potential partners to ensure that parks, facilities, and habitat area remain vital assets for the community. Planning Process Over the next 8 months, Island County will engage in a three-phased planning process (Figure 1). The process will rely on direction from the County and the WCLT, as well as feedback from the public during every phase of the plan. Figure 1: The Planning Process Island County Parks and Habitat Conservation Plan 1 Phase 1: Where Are We Now? The first phase includes a review and inventory of County-wide resources, as well as creation of maps. This phase includes an analysis of County demographics, land use and park operations to provide a foundation for the planning effort.

  • Island County Profile
    Island County profile by Anneliese Vance-Sherman, Ph.D., regional labor economist - updated October 2017 Overview | Geographic facts | Outlook | Labor force and unemployment | Industry employment | Wages and income | Population | Useful links Overview Regional context Island County is situated in the Salish Sea in Northwest Washington. As its name suggests, it is made up of several islands. The two largest are Whidbey and Camano. Island County is the second smallest county in Washington by landmass, just larger than neighboring San Juan County. Island County is bounded to the north by Deception Pass and by Puget Sound to the south. Skagit Bay and Saratoga Passage are located to the east and Admiralty Inlet and the Strait of Juan de Fuca are west of Island County. Skagit and Snohomish Counties lie to the east of Island County and the Olympic Peninsula lies across the water to the west. Island County is one of 6 counties included in the Seattle-Tacoma Consolidated Metropolitan Statistical Area (CMSA). The largest employer is the U.S. Naval Air Station in Oak Harbor (Naval Air Station Whidbey Island or NASWI). Oak Harbor is the largest city in the county with an estimated population of 22,840 in 2017. Local economy For thousands of years, Island County was inhabited by several groups of Coast Salish Indians. In the late 1700s and early 1800s, the population was decimated by disease transmitted through contact with European and American explorers. Settlement by non-indigenous people began in the 1850s. Early industries included logging, fishing and farming, as well as some related manufacturing industries.

  • Sediment Dispersal and Accumulation in an Insular Sea: Deltas of Puget Sound
    Sediment dispersal and accumulation in an insular sea: deltas of Puget Sound Kristen L. Webster A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy University of Washington 2013 Reading Committee: Andrea S. Ogston, Co-Chair Charles A. Nittrouer, Co-Chair Mark Holmes Program Authorized to Offer Degree: Oceanography ©Copyright 2013 Kristen L. Webster University of Washington Abstract Sediment dispersal and accumulation in an insular sea: deltas of Puget Sound Kristen L. Webster Co-Chairs of the Supervisory Committee: Associate Professor Andrea Ogston Professor Charles Nittrouer Oceanography Small rivers carry several million tons of sediment annually into Puget Sound and the Strait of Juan de Fuca. Once delivered to the marine environment, processes in the water column and on the seabed dictate dispersal, deposition and accumulation of these particles. To investigate these mechanisms, water-column measurements, including long-term bottom-boundary-layer time-series, water-column profiles and shipboard velocity, and seabed sampling, such as sediment cores, multibeam bathymetry and seismic reflection profiling, were collected from 2007-2009 on the Elwha and Skagit River deltas. Tidal currents at both study sites were strong and capable of dispersing muds to more distal portions of the delta. At the Skagit delta the intertidal topset had strong ebb tidal currents that exported most of the Skagit River mud rapidly beyond the topset. The mud found on the flat was limited spatially, near channels and at the outer flat edge and temporally, following high discharge. Physical processes drive shear stresses that act on the seabed to mobilize sands and muds and rework the seabed at various frequencies and depths: on a semi-diurnal tidal timescale, both channel and flat seabeds are reworked to 1-2 cm; and over a decadal timescale, lateral channel migration acts to rework the seabed to 1-2 m, making the limited mud deposits available for export.
