• Creating or enhancing access to places for physical activity can result in a 25% increase in the percentage of people who exercise at least 3 times/week

Total city population:

397,067

Zip code 94601

population: 55,425

Existing Park Space• Zip code 94601 total area: 3.38 sq.mi.

Current Situation• Park area: 0.03 sq.mi.• Area of zip code located within 0.25mi of a park: 0.57 sq.mi.• Total coverage (park area + park service area): 0.60 sq.mi.

17.86% of zip code area is within 0.25 miles of a park

≈18% of zip code area is within 0.25

miles of a park

Proposed Policy Change

• Establish joint use agreements with the 8 schools located in zip code 94601 to increase local children’s access to spaces for physical activity

8 schools total

6 schools are located >0.25 miles

from a park

It is recommended to establish joint use agreements at all 8 schools, given low student Fitnessgram

scores at all 8 schools

California Fitnessgram Categories• 1) Aerobic Capacity

– PACER (Progressive Aerobic Cardiovascular Endurance Run)– One-Mile Run– Walk Test (only for ages 13 or older)

• 2) Abdominal Strength and Endurance– Curl-Up

• 3) Upper Body Strength and Endurance– Push-Up– Modified Pull-Up– Flexed-Arm Hang

• 4) Body Composition– Skinfold Measurements – Body Mass Index– Bioelectric Impedance Analyzer

• 5) Trunk Extensor Strength and Flexibility– Trunk Lift

• 6) Flexibility– Back-Saver Sit and Reach– Shoulder Stretch

Note: Learning Without Limits school was founded in 2009, thus there is no data available from the 2008-2009 Fitnessgram

Adding Spaces for Physical Activity• Zip code 94601 total area: 3.38 sq.mi

By adding joint use agreements at 8 schools• Area of zip code located within 0.25mi of schools: 0.70 sq.mi.• New total coverage (parks + park service area + school

service area): 1.31 sq.mi.

38.65% of zip code area is within 0.25 miles of a park or school

≈39% of zip code area is within 0.25 miles of a

park or school

Impact of establishing Joint Use agreements

at 8 local schools

116% increase in proportion of zip

code area covered

• Geocoded school names and addresses in ArcMap and created a layer file and shapefile

Original Data

Process:

• Located Fitnessgram data for 94601 schools on California Department of Education website

•Input Fitnessgram into Excel

• Created a model to join school shapefile with Fitnessgram data spreadsheet ,and added the resulting parameter to future maps

Metadata for my original

“OUSD_94601_ Schools_Fitgram”

layer file

Skills Demonstrated1. Modeling: created a model to join schools shapefile with Fitnessgram data (slide 25)

3. Measurement/Analysis: measured total area of park space, park service area, and school service area in zip code 94601

(map 4/slide 11 and others)

4. Original data: created original “OUSD_94601_Schools_Fitgram” layer and shapefile (data shown on map 6/slide 15,

process described on slides 23-24)
