Temporal and Spatial changes in Coastal Geomorphology, Coos County, Oregon
The objective of this study was to produce updated information on the spatial extent of beach and dune geomorphology in Coos County, Oregon that may be subject to existing and future storm-induced wave erosion, runup, overtopping, and coastal flooding. These data are of importance to the Department of Land Conservation and Development and the seven coastal counties of Oregon in order to implement Statewide Planning Goal 18: Beaches and Dunes. Oregon Statewide Planning Goal 18 requires local jurisdictions adopt a beach and dune overlay zone in their comprehensive plan, which may be used to manage development on or near beaches and dunes. Regional mapping of the coastal geomorphology of the Oregon coast to define the extent of its beaches and dunes was originally undertaken between 1972 and 1975 by the U.S. Department of Agriculture Soil Conservation Service (USDA, 1975). However, in the intervening 45 years, much has changed on the coast. Of particular importance has been the proliferation of European beach grasses that have helped stabilize many coastal dune systems, the growth and northward extension of the New River Spit, while many areas of the Coos County coastline have experienced erosion (e.g., Bastendorff Beach, North Coos Spit), especially since the late 1970s. In addition, new technologies such as lidar are now providing unprecedented levels of detail, enabling scientists to map the spatial extents of both the contemporary and historical foredune systems more accurately as well as much older inland dunes. These three factors combined necessitate that the USDA (1975) overlay zone be updated to reflect contemporary conditions. This layer defines the the spatial extent of beach and dune morphologies. [Draft] See the text from this Open-file Report O-24-XX for technical information on mapping methods and a discussion of results and interpretation.
The objective of this monitoring program is to document the response of Oregons beaches to both short-term climate variability (e.g., El Nios, extreme storms) and longer-term effects associated with the changing climate of the earth (e.g., increasing wave heights, changes to storm tracks, and sea level rise), that will influence the stability or instability of Oregons beaches over the next century.
This project was funded under award #21102 by the Oregon Coastal Management Program (OCMP) of the Department of Land Conservation and Development agency, via a National Oceanic and Atmospheric Administration (NOAA) Office for Coastal Management Special Merit Grant. We thank Rhiannon Bizore for her assistance throughout this project, discussion on approach, and constructive comments on the technical report. We also thank Meg Reed for her perseverance in finding the needed funding to complete this important update.

Attribute accuracy is good.
Topology was checked and all errors were fixed. Attributes were visually reviewed.
This dataset is complete for coastal Coos County, Oregon.
Accurate to the scales mapped.
For the wet flood plain and wet surge plain, vertical accuracy is entirely dependent on accuracy of the lidar used, typically within 15 cm in open space (flat) areas.
Beach and dune features along the coastline were defined in a geographical information system (GIS) and informed by historical and contemporary aerial, airborne lidar, coastal erosion, FEMA flood modeling, recent coastal change analyses derived from lidar data, geologic mapping, monitoring, and other sources. This layer was generated using Esri ArcGIS 10.7 and Esri ArcPro 3.2 software.
