Addressing Lack of Park Space in Los Angeles Ryan Johnson UP 206 Final Presentation March 14, 2011
The Issue • More than 70% of Angelenos lack park access within 1/4 mile of home. • In Los Angeles, white neighborhoods (>75% of residents) boast 31.8 acres of park space for every 1,000 people, compared with 0.6 acres in Latino neighborhoods. • Strong correlations between levels of physical activity and both ethnicity and poverty status.
Objectives • Provide more green space in the City • Focus on West San Fernando Valley • Find suitable vacant lots for redevelopment along the LA River • Address equity and health concerns
Hot Spot Analysis: Index • % Hispanic Population: (x2) • % Foreign Born (Non-Citizen): (x2) • Distance from Park (x2) • % of HH with No Vehicle (x1) • Population Density (x1) • % Under 18-years-old (x1) • Median HH Income (x1)
Recommendations • Develop the vacant lot adjacent to Canoga High School • Collaborate with river revitalization organizations
Skills used • Required: • Original Data: • The SW San Fernando Valley shapefile, from the larger LA Communities file • Measurement/Analysis: Maps 10a-c • Measured ½ mile from the vacant lots, then drew a circle around the lots. • Hotspot Analysis: Index of Park Need • Model: Slide 17 (Features to Rasters) • Metadata : Slide 18 • Others: • Inset Map • Geoprocessing: • Clipping– multiple • Dissolve – Dissolved the interior lines when making the SW SFV shapefile • Buffering: • Around the parks • Around vacant lots • Boundary sub-sets selections: Creating SW SFV neighborhood • “SwSFV” was derived by selecting tracts in the View from LA Communities shapefile and converting to a new shapefile • Attribute sub-sets selection: • Created the shapefile of vacant lots along LA River by selecting Lots within the SW SFV boundary that intersect with the LA River • Created new “LA River” shapefile by querying for “los angeles river” in the LA County Rivers file and exporting the result as a new shapefile • Point Graduated Symbol • Pct Under 18
