Seattle Monorail Impact Project A GIS Study on Impacts of the New Seattle Monorail By: Wiley Coffin, Kyle Crass, Kyle Freeman, Ken Hunziker, Tony Marti

Project Goals • Use GIS to create digital map of proposed monorail project • Link GIS map to census data for public impact analysis • Analyze impact of project on residents near and on proposed monorail route

Using GIS to Create Digital Map of Proposed Monorail Project • Find data sources: – www. wagda. lib. washington. edu • Download appropriate shape files for city of Seattle: Street network, Building outlines, City outline, Shoreline • Import sources into GIS and overlay shape • • files Create new shape files of proposed monorail route and station locations – Create shape files in Arc. Catalog – Digitize route and station location in Arc. Map Overlay new shape files into Arc. Map

Link GIS Map to Census Data for Public Impact Analysis • Download census data from ESRI website and add to Arc. Map – King County Census 2000 blocks shapefile and attribute data • Integrate city of Seattle data with King • County Census data – Specify City of Seattle data coordinate system – Overlay Census data onto our monorail map Join attribute table of census data and census block attribute table

Analyze Impact on Residents Near and on Proposed Monorail Route • Create multiple buffers around stations and route – Station Buffers-1 km total donut buffer around each station – Route Buffers-250 m buffer on each side of route

Analyze Impact on Residents Near and on Proposed Monorail Route • Use Census 2000 block data to analyze its spatial relationship to the buffers – Select by Location – Statistics to find sum of population within parameters

Results • Positively affected people – 81, 000 individuals living in buffer zones • Negatively affected people – 18, 000 individuals living in buffer zone • Negatively affected are also Positively affected • Further information for different population demographics can be determined from this data
