Description:

Abstract:
This spatial digital file provides a polygon delineating the evacuation area for Netarts-Oceanside-Cape Meares, along Oregon's coast. The evacuation area was incorporated into a Tsunami evacuation map for Netarts-Oceanside-Cape Meares published as a brochure. To view and access the brochure, please link to the following URL : <http/www.oregongeology.com>. This link takes you to the Department of Geology and Mineral Industries' (DOGAMI) website where a pdf of the brochure can be downloaded.
Purpose:
The purpose of the spatial digital file is to illustrate the evacuation area for a Tsunami affecting Netarts-Oceanside-Cape Meares and adjacent areas. A map of the Tsunami evacuation area for Netarts-Oceanside-Cape Meares was compiled to provide information on the Tsunami phenomena for public awareness.
Supplemental Information:
INUNDATION vs EVACUATION: The inundation lines (boundaries) are scientific products aimed at showing ""best available science"" estimates of flooding potential and uncertainties in these estimates. Evacuation lines may or may not correspond to inundation lines where both are present. Evacuation lines are established in partnership with local government and may add conservatism to inundation boundaries, based on the needs of local emergency planners. Inundation polygons in some cases cover much larger areas than the evacuation areas, going outside of UGB's that generally bound evacuation areas. Both are useful products but are also distinct.

See Oregon Department of Geology and Mineral Industries (DOGAMI) Open-File Report O-97-34 (Priest and others, 1997) for a detailed explanation of the mapping techniques (to order this publication and others go to world wide web site http://www.oregongeology.com/default.htm ).

Access Constraints:
This spatial data file is a deliverable to Oregon Department of Land Conservation and Development. Eventually, this spatial data file will be incorporated into the Oregon Coastal Atlas, a collaboration of the Oregon Ocean-Coastal Management Program, Oregon State University and Ecotrust. Dogami does not intend to publish the spatial data files as a new agency publication, nor provide a plot-on-demand paper display of the spatial data files.
Use Constraints:
The spatial digital file can be used to depict a Tsunami evacuation area. Bear in mind that this particular Tsunami evacuation area is subject to interpretation. Any Tsunami evacuation or hazard map created from the spatial data file or derivatives thereof is not a substitute for site-specific investigations by qualified practitioners. It may be used as a general guide for emergency evacuation. The user is responsible for the appropriate use of this data.

To avoid the risk of misinterpretation, invalid results, and erroneous conclusions, the users must consider the original map scale, collection methodology, currency of data, and any other conditions specific to every data element and each dataset as a whole. Potential users are advised to consult with DOGMAI to gain an understanding of the inherent limitations of this data set and its scope of inference. Also, the user must be aware that errors and conditions originating from physical sources involved in developing a dataset may be reflected in the data, and that the digital processing performed during preparation, storage, and transmission of the dataset may have exacerbated such errors and/or introduced additional ones.

These data are subject to change. Acknowledgment of the DOGAMI would be appreciated in products derived from these data. DOGAMI is providing this data because the subject matter is consistent with the mission of the Department.

Attribute Accuracy:

Attribute Accuracy Report: Accuracy of area and length attributes is unknown. No report accompanies the spatial data files.

Logical Consistency Report:
Spatial data is presented in the form of a single polygon delineating the potential Tsunami evacuation area for Netarts-Oceanside-Cape Meares. Areas not in the evacuation area are not accounted for spatially. This dataset does not have topology. This data is not field-checked and it could be an interpretation of a model. No guarantees are provided as to its accuracy.
Completeness Report:
This data set was developed to illustrate the evacuation area from the affects of a Tsunami in Netarts-Oceanside-Cape Meares. Not all communities along Oregon's coast have a Tsunami Evacuation Map that outlines the evacuation area for a Tsunami. All geospatial database elements are attributed.
Positional Accuracy:

Horizontal Positional Accuracy:

Horizontal Positional Accuracy Report:
Mapping of inundation boundaries was adjusted to best available local topography, which varied from area to area but was never more accurate than plus or minus 1 foot vertical and generally is no better than plus or minus 5 ft vertical; horizontal accuracy was generally no better than plus or minus 20 feet. Overall, the data cannot be more accurate than the model from which it was developed. Positional accuracy of inundation boundaries vary based on the techniques and quality of modelling. Still the horizontal accuracy of the coverage should be regarded as unknown.
Vertical Positional Accuracy:

Vertical Positional Accuracy Report: None

Process Step:

Process Description:
PROCESS for EVACUATION POLYGONS: An evacuation polygon(s) was mapped by DOGAMI in collaboration with Oregon Emergency Management (OEM) and local government officials based on best available estimates of tsunami flooding potential. Estimates of worst-case tsunami flooding elevation from nearby areas or, if available, numerical simulations of worst-case tsunami inundation were the starting point for drawing evacuation zones (see PROCESS FOR INUNDATION MAPS below). The draft zones were reviewed in the field with local officials who then worked with DOGAMI and OEM to make any needed modifications to meet local needs. In some cases evacuation zones were modified slightly to coincide with landmarks like roads. In other cases the zones were modified to add elevation for more safety. After these alterations were made and sent to local government for approval, the evacuation brochure was designed and printed by DOGAMI. All brochures are available for download as PDF files from the DOGAMI website: <http//:www.oregongeology.com>. Mapping of evacuation boundaries was adjusted to best available local topography, which varied from area to area but was never more accurate than plus or minus 1 foot vertical and generally is no better than plus or minus 5 ft vertical; horizontal accuracy was generally no better than plus or minus 20 feet.

PROCESS FOR INUNDATION MAPS: Inundation areas were produced from three scenario Cascadia subduction zone earthquake sources (least-, middle- and worst-cases) using standard tsunami simulation software to estimate potential inland inundation. See GMS-99 for general description of mapping technique and the references below.

The simulation techniques are also discussed by Myers and others (1999) and Priest and others (2000). These last two references can be downloaded at: <http://www.ccalmr.ogi.edu/STH/online/volume17/number1/mbp/> and <http://epubs.lanl.gov/tsunami/ts182.pdf>.
