Description: One street intersection for an XY location. Contains all intersecting roads for each location. Derived from the Washington County centerline.
Description: These contours were extracted from 2 foot contours. The 2 foot contours were generated primarily from a 2014 LiDAR-based DEM dataset acquired by Oregon Metro. Historical LiDAR-based DEM data were used to augment the 2014 DEM as necessary to provide complete coverage for the Tualatin Watershed. The general contour generation process was: 1) Apply evenly weighted 5x5 smoothing to DEM via convolution function 2) Generate contours from smoothed DEM using gdal_contour utility 3) Split contours into 1000 ft segments 4) Remove contours with circumference less than 100 ft 5) Build geometry and attribute indices.

Description: The section feature class provides a geographic presentation of section lines within each township in Washington County. Theoretically, each section is a square tract of line one mile by one mile containing 640 acres. The section lines have been updated based on true ground monuments if such physical evidences are available. Key attribute fields are:TILE_NAME: The tile name, such as "3N5W06".Section: Section number, such as "06".

Description: The National Flood Hazard Layer (NFHL) data incorporates all Flood Insurance Rate Map (FIRM) databases published by the Federal Emergency Management Agency (FEMA), and any Letters of Map Revision (LOMRs) that have been issued against those databases since their publication date. It is updated on a monthly basis. The FIRM Database is the digital, geospatial version of the flood hazard information shown on the published paper FIRMs. The FIRM Database depicts flood risk information and supporting data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual-chance flood event, and areas of minimal flood risk. The FIRM Database is derived from Flood Insurance Studies (FISs), previously published FIRMs, flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by FEMA. The NFHL is available as State or US Territory data sets. Each State or Territory data set consists of all FIRM Databases and corresponding LOMRs available on the publication date of the data set. The specification for the horizontal control of FIRM Databases is consistent with those required for mapping at a scale of 1:12,000. This file is georeferenced to the Earth's surface using the Geographic Coordinate System (GCS) and North American Datum of 1983.
