These maps delineate the entire Puget Sound shoreline by geomorphic type. The primary purpose of the mapping was to identify feeder bluffs, eroding shorelines that are important to maintaining nearby beaches. Knowledge of the distribution of these features can be used by local planners and resource agencies to better manage Puget Sound shorelines. The study emphasized mapping of coastal bluffs, but also extended to a wide range of other coastal landforms, including rocky shores, river deltas, and small lagoons and estuaries.
