The point locations are created from the centroids of building footprint polygons. The attributes were based on Clackamas County assessor's data, which were joined to the UDF points via Taxlot or parcel data. The purpose of this dataset is to show the building locations of Clackamas County. UDF building points were attributed with assessor's data for developing building characteristics. Point locations were intersected with hazard data to calculate risk from natural hazards and to estimate the level of vulnerability for communities within the study area. This dataset is a DOGAMI created feature class that is derived from DOGAMI digitized building footprints or parcel data geometry (with assessed structures on it) when building footprint coverage was not available. Parcel data geometry was provided by the Clackamas County Assessor's Office. 2024CompleteNone plannedISO 19115 Topic CategorygeoscientificinformationlocationstructureOregon Geospatial Enterprise Office Metadata Keyword Thesaurususer defined facilitiesUDFbuilding pointsfootprintshazus buildingsOregon Geospatial Enterprise Office Metadata Keyword ThesaurusClackamasOregonOregon Geospatial Enterprise Office Metadata Keyword ThesaurusBuilding spaceOregon Geospatial Enterprise Office Metadata Keyword ThesaurusNoneREPORT DATA: This product is for informational purposes and may not have been prepared for or be suitable for legal, engineering, or surveying purposes.

While this is not a perfect process, it was the best available method for the purposes of this report. Inaccuracies and vagueness found within the assessor's database contributed to the necessity of following "rules of thumb" and making use of default values for about 20 percent of the UDFs. Also inconsistencies between the number of structures on a given parcels shown in the assessor's data with the number of UDFs further complicated the joining of the table data (assessor's) with the spatial data (building points). A considerable amount of ground truthing using a variety of resources, as well as thorough review from knowledgeable personnel reduced the number of inaccuracies to an inconsequential level. The "eqDesignLevel" were derived from the "YearBuilt" and information regarding local seismic building codes. The "eqBldgType" was randomly assigned on a Census Tract basis from a script that based the distribution of building type to the UDF's from building inventory information stored in the Census Tract areas. All fields included in the UDF_full_results dataset are complete and attributed correctly. UDF points represent the known buildings within the study area. Points were derived from building footprints or parcels when footprints were unavailable. Attributes were obtained from assessor data. The scale that this dataset was digitized at was 1:2,000.Not ApplicableOregon Department of Geology and Mineral Industries 2024Multi-Hazard Risk Assessment for Clackamas Countyvector digital dataPortland, OROregon Department of Geology and Mineral Industries https://www.oregon.gov/dogami/pubs/pages/index.aspx2024DOGAMIThis dataset is a DOGAMI created feature class that produced from the centroid of the building footprints using a Polygon to Point GIS tool. Where building footprints were unavailable the centroid of the parcels containing structures were used in their place. UDF points were attributed through a two step process. In the first step, UDF points were attributed with a Maptaxlot ID using a spatial join with the parcels layer. Using the Maptaxlot ID, the assessor's data is mapped to the UDF points. Sorting based on square footage is used to guide the assessor data to UDF point transference. Hazard results were produced through Hazus analysis (Earthquake or Flood) or exposure analysis (Landslide and wildfire)Oregon Department of Geology and Mineral Industries mailing and physical address
