Marine shoreline information

Coastal Zone Atlas of Washington

Scale: 1:24,000

Date: 1978-1980. Some portions of Atlas have now been digitized, but no attempt has been made to update original mapping.

Coverage: Marine shorelines inside of Neah Bay: Strait of Juan de Fuca, Puget Sound, and the Strait of Georgia. Includes 12 counties, but excludes tribal and federally owned lands. Mapping includes nearshore zone and extends inland 2000 feet.

Description: Prepared in the late 1970s and published in individual volumes for each of twelve counties. Contains maps in six categories: Geology, Slope Stability, Coastal Flooding, Sand and Gravel/Critical Biological Areas, Coastal Drift, and Land Cover/Land Use.

Slope Stability. Relative mapping of slope stability (Unstable, Intermediate, Stable) and delineation of both historic and recent landslides. Relative stability maps remain useful for identifying potentially unstable areas and serving as threshold for more detailed geotechnical evaluations. Maps of recent slides seriously out of date.

Coastal Drift. Maps of littoral drift, beach substrate, bluff erosion, and wave energy. In principle, very useful information, but numerous problems with data. Wave and drift information is locally inaccurate, and for littoral drift, the Net Shore-Drift reports are recommended instead. Bluff classification indicates importance as sediment sources (feeder bluffs), but we are aware of no efforts to date to verify the accuracy or applicability of this information. We are aware of some local inaccuracies. Beach substrate information may also be useful, but will probably need to be checked against more recent Shore Zone data to assess its quality and usefulness.

Contact: Out of print. Most local planning departments have copies.

Shore Zone Data

Scale: 1:24,000
Date: 2000.
Coverage: All marine shorelines.

The inventory segments the shoreline into homogeneous units, roughly corresponding to littoral drift cells. Data was collected by video taken from helicopter, with voice over descriptions of shoreline geology and botany, and was digitized as ArcInfo layers; available on CD-ROM.. Videotapes are available for further analysis. Information includes:

  • Vegetation (e.g., eelgrass, kelp, surfgrass, green algae, Sargassum)
  • Geomorphic form
  • Geomorphic material such as boulder, cobble, pebble, sand for subtidal, intertidal, and supratidal
  • Wave exposure
  • Segment length (feet)
  • Sediment source and abundance
  • Shoreline modification (e.g., bulkheads, piers, docks, slips)
  • Riparian overhang
  • Shoreline type
  • Oil residence index

Puget Sound Ambient Monitoring Program (PSAMP), Nearshore Habitat Inventory Component

Scale: 1:12,000 (4-meter pixel)
Date: 1995-1996
Coverage: Marine waters in Whatcom County, Skagit County, and North Whidbey Island.

Description: Detailed near-shore habitat information. Data source is aerial photography with field work and remote sensing. Information available on CD.

Especially useful for estuaries and mudflats and includes canopy vegetation, intertidal vegetation, animals, substrate, and wave energy.

Intertidal Bait Fish Spawning Beach Survey Project

Scale:1:24,000 charts
Coverage: Approximately 75% of Puget Sound

Description: The survey documents existence of forage fish spawning grounds on Puget Sound beaches. Information was obtained through extensive site visits. Information is available as a GIS layer.

The coverage is limited to 75% of Puget Sound because funding for the study was terminated after the 3rd of four funding cycles. A new inventory by the NW Straits Commission is being undertaken in Snohomish, Skagit, San Juan, Island, Whatcom, Jefferson and Clallam Counties. This will complete the WDWF inventory for these areas, but an inventory for the South Sound is yet to be programmed.

Net Shore-Drift Reports, Department of Ecology

Scale:mostly 1: 24,000
Date:1979-1995, most in early 1980s
Coverage:Washington's marine shorelines (Outer Coast and Puget Sound)

Description:Maps indicating direction of net shore-drift and approximate boundaries of individual drift (or littoral) cells. For most, but not all areas, short narratives describe the evidence for littoral drift within each cell. Drift information is available in a series of Department of Ecology reports, or for the Port Townsend 1:100,000 quadrangle, as a US Geological Survey map. Drift information has recently been digitized by Ecology. CDs are being created county-by-county. Contact Cinde Donoghue to find out if your county is ready. For the Southwest Washington coast, much of this information is superseded by research generated by the Southwest Coastal Erosion Project.

Oblique aerial photos of marine shorelines

1992 - 1997 coverage: Each photo is approximately * to 2/3 mile of shoreline, 1 inch = 250 feet. (Photos were scanned from slides).

2001- 2002 coverage. Each digital photo is approximately 150-200 feet of shoreline, 1 inch = 75 feet. Resolution is at 300 pixels per inches. (Photos are being shot digitally). CDs are being created county-by-county as they are shot. We expect that all marine shorelines in state will be covered by summer 2002. Contact Cinde Donoghue to find out if your county is ready. 

Coverage:Washington's marine shorelines (Outer Coast and Puget Sound)

Description:oblique aerial photography of the state's entire 2,500 miles of marine shoreline. More than 10,000 true-color photos comprise a continuous series, panning left to right along the shoreline. The photos were taken to optimize sun angle, shoreline orientation, and low tides. Oblique photos are useful for interpreting bluff geology and land-sliding, riparian vegetation, and shoreline modifications such as bulkheads and seawalls.

WDFW Priority Habitats and Species Inventory


Date:1990s see web site


Description: The Priority Habitats and Species (PHSPOLY) Database consists of polygons that describe occurances of priority habitats and species. Priority habitats are those habitat types with unique or significant value to many fish or wildlife species. Priority species are those fish and wildlife species requiring special efforts to ensure their perpetuation because of their low numbers, sensitivity to habitat alteration, tendency to form vulnerable aggregations, or because they are of commercial, recreational, or tribal importance. All priority species mapped areas represent known use areas; they are not potential habitats. PHSPOLY may include locations of federal and state listed species (threatened, endangered, sensitive, candidate) and other priority non-game and game species. Locational data are associated with tables detailing each priority habitat and species. PHSPOLY data are compiled by WDFW biologists using the best information available from research efforts, surveys, or field observations.
