Berkeley residents are concerned
about the environment, but sustainable
businesses are not always accessible or
advertised to them. We wanted to help
residents be conscious consumers by
identifying the most accessible of
Berkeley’s certified “Green” restaurants.
Approach
Accessibility Factors
1. Green restaurants:
greenbiz.ca.gov
2. Census, network, & contour data:
GEOG/LDA C188, Prof. John Radke
3. Price, Restroom, ADA, and dietary
accessibility:
Yelp, individual restaurant websites
and phone calls
4. Transportation data:
UC Berkeley geodata
Source Data Collection
Projection &
Datum
All of our data is
projected in NAD 83
State Plane III (US ft)
Three Analysis Methods
Suitability
Digitize each restaurant
Create attribute table of
accessibility factors
Assign weights
Add weights together
3D Analysis
Create Triangulated Irregular
Network from contours
Select and export slopes of 0-5
degrees for wheelchair access
Network Analysis
Service Area
Create service area around
AC Transit bus stations with
100 meter breaks
Create service area around
BART stations with 500 meter
breaks.
Export service areas to
individual layers
Union transportation service
areas with wheelchair access
Target Market Share
Set Target Market Share (%)
to 75
Set Impedance Cutoff to 1
mile (1609 meters)

only the most accessible restaurants.
Conclusions
Total Accessibility
highlights several important
things. First, most of the
certified green businesses
are concentrated around
campus and the
accessibility of the
restaurants and landscape
across Berkeley varies
greatly. This demonstrates
the importance of having a
database of business
practices for consumers,
not only for green
businesses, but for all
businesses in general.
Additionally, while a
business itself may be
accessible, the surrounding
area may not be, and vice
versa.
The target market share
analysis demonstrates that
the four green restaurants
that can serve 75% of the
population (in black) are not
necessarily the most
accessible. When we ran
the target market share
again with only restaurants
of the highest 2 accessibility
ratings (in blue) as possible
facilities, we needed more
businesses to
accommodate the same
number of people. However,
there were two businesses
that were both the most
accessible and the most
convenient: Le Bateau Ivre
and Sweet Adeline Bakery
(seen in the target market
share maps as the
southernmost overlapping
icons).
