• Koreatown in the City of Los Angeles has been a
  meaningful place for Korean immigrants and
  visitors from Korea. It is the largest Korean
  Community outside of Korea.
• The demography of Koreatown is changing.
  According to SCAG Region Compass Blueprint Case
  Study, Koreatown is home to concentrations of
  ethnicities other than Korean Americans,
  including Hispanic, Chinese, Japanese, Filipino,
  Bangladeshian and other Asian Americans.

Mapping Plan

• Phase I
• Identify boundary of Koreatown
• Identify ethnicity in Koreatown
• Analyze the spatial patterns for different users
  groups

• Phase 2
• Identify open space in Korea town
• Identify transportation mode as a way to connect
  open space
• Conclusion

Ethnicity
The percentages of Asian and Latino people are
high for the county. Highly diverse for the city
of Los Angeles and highly diverse for the county

Space use by Ethnicity
Asian
Hispanic

Zoning map and Ethnicity
There is a relationship between Zoning and
spatial pattern of Ethnic groups. Hispanics live
northeast of the major commercial area (map on
the left) but few individuals live near the
commercial area (refer to ethnicity
map). Therefore, we can conclude that the
commercial area is Korean dominated.

Spatial Pattern

• Korean Restaurants
• Mexican Restaurants
• Bangladesh Facilities

Buffer Zones
12
Where is a opportunity spot for ethnic fest?
Currently, Open spaces are on the edge of
Koreatown. There is no space where different
ethnic groups can celebrate together .Thus it is
likely to be used by certain ethnic group.
13
Percentage of Public Transportation users
It is necessary to change routes of existing
public transportation or implement new
transportation system
14
Suggestion fixed guide rail system
15
Potential route for new transportation
New transportation can be a circulative loop that
connects cultural centers of each ethnicity.

Findings

• The boundary defined by census does not match
  with actual spatial use in Koreatown.
• Each ethnic group forms its own spatial boundary
  and tends to gather around space associated with
  each culture.

Conclusion

• There is no central open space where different
  ethnic groups can celebrate together.
• It is required to change current public
  transportation routes or implement new system in
  order to make closed loop for each community
  centers.
