This data layer is an element of the Oregon GIS Framework. This theme delineates Urban Growth Boundaries (UGBs) in the state of Oregon. Oregon land use laws limit development outside of urban growth boundaries. The line work was created by various sources including the Oregon Department of Land Conservation and Development (DLCD), the Oregon Department of Transportation (ODOT), Metro Regional Council of Governments (Metro), county and city GIS departments, and the Oregon Department of Administrative Services - Geospatial Enterprise Office (DAS-GEO). Urban growth boundaries (UGBs) are lines drawn on planning and zoning maps to show where a city expects to experience growth for the next 20 years. UGBs were established under Oregon Statewide Planning Goals in 1973 by the Oregon State Legislature (Senate Bill 100). Goal 14 specifically deals with UGBs (OAR 660-15-0000(4)). Other specific ORS that relate to the designation and delineation of UGBs are: 197.626 Expanding urban growth boundary and designating urban reserve area subject to periodic review. A city with a population of 2,500 or more within its urban growth boundary that amends the urban growth boundary to include more than 50 acres or that designates urban reserve areas under ORS 195.145 shall submit the amendment or designation to the Land Conservation and Development Commission in the manner provided for periodic review under ORS 197.628 to 197.650. [1999 c.622 §14; 2001 c.672 §10] and 197.628 Periodic review; policy; conditions that indicate need for periodic review.(1) It is the policy of the State of Oregon to require the periodic review of comprehensive plans and land use regulations in order to respond to changes in local, regional and state conditions to ensure that the plans and regulations remain in compliance with the statewide planning goals adopted pursuant to ORS 197.230, and to ensure that the plans and regulations make adequate provision for needed housing, employment, transportation and public facilities and services. Determining UGBs in Oregon is done based on input from city and county governments. Such special districts as public safety and utilities also participate because they provide important services. Local citizens and other interested people also provide input at public hearings, and by voting. After local governments determine the UGB, they submit a Post Acknowledgement Plan Amendment and the state Department of Land Conservation and Development (DLCD) reviews it for consistency with Goal 14. As part of this process jurisdictions send GIS files to DLCD highlighting the amended area. UGBs that are currently in the appeal process at the time of publication are not included. The effDate attribute is populated to indicate the data version and year in which the UGB was updated. UGB amendments are verified with DLCD’s Post Acknowledgement Plan Amendment (PAPA) database to ensure that all UGB updates reported to DLCD have been included in this data. In 2019 DLCD acknowledged amendments to the following UGBs: Madras, Mill City, Redmond, Springfield and Stanfield.
This data set delineates geological seafloor characteristics of the continental margin of the United States West Coast adjacent to Washington, Oregon, and Northern California. The data set depicts seafloor substrate types as interpreted from a multitude of seafloor mapping surveys, including multibeam sonar, sidescan sonar, sediment grab samples, cores samples, seismic reflection profiles, and still or video images. Seafloor types are classified according to three unique classification schemes: (1) The Active Tectonics and Seafloor Mapping Lab's SGH codes, (2) Greene et. al. (1999) deep-water marine benthic habitat scheme, and (3) the Coastal and Marine Ecological Classification Standard's Substrate Component. This dataset has been developed since 2002 and is now at version 4.0. Version 4.0 SGH Map provides significant changes and modifications from previous versions. The major modifications from previous versions are as follows: 1. Merged in new local-scale habitat maps from detailed mapping at 13 sites over Washington, Oregon, and Northern California. 2. Implemented numerous attribute table clarifications and modifications including a clarification of the use of primary, secondary lithologic type. 3. CMECS Substrate Component codes added by crosswalking SGH codes to CMECS SC codes. 4. Appended habitat polygons for Northern California from the 2005 EFH Consolidated GIS Volume 1 (2004) data set geohab_woc.shp developed by Gary Greene and the Center For Habitat Studies at Moss landing Marine Labs. Significant modifications or updates to continental shelf and slope habitat types of Northern California were made to the Greene et al. map based upon newly available bathymetry in the region. 5. Appended California State Waters mapping Program Tier II map products for northern California. The Tier II habitat maps used in this regional habitat map were acquired, processed, archived, and distributed by the Seafloor Mapping Lab of California State University Monterey Bay and are available in their origianal form at: http://seafloor.otterlabs.org/SFMLwebDATA.htm
