Clallam County Maps

New Technology Web Maps are now Live!

Clallam County has transitioned to a new web mapping platform that uses current technology, and has an interface that is more like the current conventions for commercial web maps (Google, Bing, etc) Some of the functions will feel more familiar to users of other such web maps, but are very different from the web maps Clallam County has provided for the last 16 years. Most of the functions you have come to expect have been made available in some form in the new maps, and new functionality has been enabled.

See Help Links below.


Be advised that the map layers on all maps accessible from this page have limited accuracy, and do not necessarily align with one another, especially when zoomed in closer than 1:24,000. In addition, some layers may not be recently updated. Clallam County makes no warranty of the accuracy or usefulness of this data. Clallam County is actively working to update and improve this map data. It is a large and complex job, and resources are limited, so progress may appear much slower than you might like.

Additional Maps

  • Plan Section 31.02.910(4) Combined Geology and Zoning Maps

    Pursuant to Comprehensive Plan (“CP”) Section 31.02.910(4) the County makes available three maps in PDF format. They are three sections of a single electronic map, one section for the Sequim region, one for the Port Angeles region and one for the West End region. Each of the three maps shows the underlying zoning designation for the land as of the enactment date for Ordinance #968, i.e., November 10, 2020. The maps also include [represented by cross-hatching] the underlying geology [either “Qgd” representing sand & gravel, or “theta-v-c, representing basalt] that when combined with a preexisting zoning designation of “Commercial Forest” leads to automatic designation of that parcel or location as a “Mineral Resource Land Overlay District” or MRLOD pursuant to CP Section 31.02.180(3), also enacted on November 10, 2020. While these maps may be used as part of obtaining a classification score in accordance with CP Section 31.02.170(3), the County and its Department of Community Development(“DCD”) do not otherwise guarantee the accuracy of these maps and the information shown on these maps is advisory AND does not and shall not bind DCD to reach a particular conclusion regarding a permitting decision.
  • Mineral Resource Lands Maps
