SNAP-Ed Census Tract Qualification <185% All R • To qualify neighborhoods by census tracts, use new ACS 2005-2009 layer: Proportion < 185%FPL All Races • Currently only have “all races” available • In 2012 proportion < 185%FPL race-ethnic layers will be made available • Can also try: • Proportion in poverty < 100% FPL by race-ethnicity • Block Group (BG) proportion < 185% FPL All Races <100% Hisp BG <185%

8. SNAP-Ed Census Tract Qualification • If re-assessing a neighborhood: • No need to re-qualify • Mapping and field survey data collection are evaluation • Will compare current data with previous data • If identifying new areas to map: • Neighborhoods must qualify • ACS 2005-2009 data layers • Proportion < 185% FPL All Races • Proportion in poverty < 100% FPL by race-ethnicity • Block Group (BG) proportion < 185% FPL All Races

28. CX3Tier 1NA7- Pedestrian Attractions • Score of amenities within a walkable distance (1 mile) from the neighborhood school – using walkscore.com • Points based on the distance to the closest amenity by category. If the closest amenity in a category is within .25 miles, the maximum number of points are assigned. The number of points declines as the distance approaches 1 mile

29. Walk Score (walkscore.com)

30. Walk Score Methodology (walkscore.com) Walk Score Methodology • calculates the walkability of an address based on the distance from your house to nearby amenities. Walk Score measures how easy it is to live a car-lite lifestyle—not how pretty the area is for walking. The Walk Score Algorithm • uses a patent-pending system to measure the walkability of an address. The Walk Score algorithm awards points based on the distance to the closest amenity in each category. If the closest amenity in a category is within .25 miles (or .4 km), we assign the maximum number of points. The number of points declines as the distance approaches 1 mile (or 1.6 km)—no points are awarded for amenities further than 1 mile. Each category is weighted equally and the points are summed and normalized to yield a score from 0—100. The number of nearby amenities is the leading predictor of whether people walk. How it Doesn't Work • There are a number of factors (street design, safety, etc.) that contribute to walkability but are difficult to measure with an algorithm.

31. CX3Tier 1NA7- Pedestrian Attractions Exercise 1. Go to walkscore.com 2. Enter the following schools to get the scores: Bobby Duke Middle School, Coachella, CA Burnett Elementary, Long Beach, CA Sunnyside High School, Fresno, CA 3. Discuss
