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

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
