Title: Average Annual Precipitation, New York State, 1961-1990
Contributors:- Polygon data
- 2000
- Chris Daly, Spatial Climate Analysis Service
- George Taylor, the Oregon Climate Service at Oregon State University
Summary: This data set shows polygons of average annual precipitation in New York State, for the climatological period 1961-1990. Parameter-elevation Regressions on Independent Slopes Model (PRISM) derived raster data is the underlying data set from which the polygons and vectors were created. PRISM is an analytical model that uses point data and a digital elevation model (DEM) to generate gridded estimates of annual, monthly and event-based climatic parameters. These data are intended for geographic display and analysis at the national level, and for large regional areas. The data should be displayed and analyzed at scales appropriate for 1:2,000,000-scale data. No responsibility is assumed by the Spatial Climate Analysis Service, the USDA - NRCS National Water and Climate Center, the USDA - NRCS National Cartography and Geospatial Center, or the U.S. Geological Survey in the use of these data.

Title: Portland Air Toxics Solutions Data, 2012
Contributors:- Polygon data
- 2016
- Oregon Department of Environmental Quality (www.deq.state.or.us)
- Scotti Cosentino Reed; James D. Proctor. Data obtained from DEQ and processed by SR and JDP.
Summary: "In 2009, DEQ created the Portland Air Toxics Solutions project to work with local communities to develop air toxics reduction strategies for the Portland region, including portions of Multnomah, Washington and Clackamas Counties" (www.deq.state.or.us/aq/toxics/pats.htm). These data represent block-group scale modeling of air toxics risks from a variety of sources (19 pollutants total), prepared in 2012 with model extrapolation to target year 2017. The study led to a number of priorities and ongoing management/policy discussions regarding Portland air quality. Data included here generally represent a ratio of pollutant concentration to ABC (ambient background concentration) for that pollutant, implying relative risk from each pollutant; see attribute file for details.

Title: Portland Urban Growth Boundary (UGB)
Contributors:- Polygon data
- 2015
Summary: The boundary controls urban expansion onto farm and forest lands. Metro is responsible for managing the Portland metropolitan region's urban growth boundary and is required by state law to have a 20-year supply of land for future residential development inside the boundary. Under Oregon law, each city or metropolitan area in the state has an urban growth boundary that separates urban land from rural land. Metro is responsible for managing the Portland metropolitan region's urban growth boundary. Land inside the urban growth boundary supports urban services such as roads, water and sewer systems, parks, schools and fire and police protection that create thriving places to live, work and play. The urban growth boundary is one of the tools used to protect farms and forests from urban sprawl and to promote the efficient use of land, public facilities and services inside the boundary.
