Tracing the path of development of Yaletown after Expo86 Geography 376 Project Kelly S Liang  1900’s: Vancouver’s first designated

commercial zone

 1930’s: light industries and warehouses  1970’s: de-industrialized; became an

• ffice/commercial town

 1986: Expo86  1987: a large portion sold to Concord Pacific;

rapid developments began

 2006: construction of Canada Line started  Find a pattern of gentrification  Explore the possibility to combine change in

land use and property value

 Examine the different factors to gentrification

and redevelopment

• Zoning
• History
• Immigration
• Etc.

 Nelson, Seymour, Beach Crescent and

Marinaside Crescent

 Defined in Yaletown, a walking tour through

history

 Focus on the older warehouse streets

 From the database

• Geography files e.g. land use, roads, etc.
• Census data (1986)/2001

 Digitized materials

• Ariel photos from GIC 1984/2004
• On-screen digitization

 BC Assessment

• Land use
• Property values 1986/2007

data digitization analysis results

Collect data from various sources Create a polygon shapefile contains all of the buildings Input the values

using keyboard Census data: join, export, explore, etc. Regression model Redevelopment Index Gentrification ratio  To determine land use in 1984

• BC Assessment microfiche

 Gentrification

• Ratio as opposed to increase
• Makes the number more significant
• Simple vs. adjusted

 Simple gentrification ratio = property value 2007 / property value 1986  Adjusted gentrification ratio = (property value 2007 / property value 1986) / average inflation in property value of Vancouver

 Provides a comparison to the rest of the city  Keeps the original ratios  Combined development indicator

• Adjust gentrification ratio / redevelopment index
• To find a way integrate change of land use and

increase in property value

 Regression model

• To examine the correlation between proximity to

water and property price

 Other factors: history, zoning policies etc.

 Centroid instead of polygon

• An attempt to solve the MAUP problem
• Tools in GIS require data to be in points

 Census data

• Explore
• Clip
• Join / relate
• Field Calculation
• Normalization
• Etc.

 Overall idea

• Gentrification should be measured with change in

land use?

• Redevelopment indicator: lack of rationale
• Gentrification= both commercial and residential

 Jack Cockwell @ BC Assessment  Dr. David Ley

 Geography project or an example of GIGO?

• Absence of reliable data
• Calculation errors
• BC Assessment: too many changes

 Broader area  Incorporate more demographic components  Separate commercial and residential  Run a different redevelopment index  Regression with factors other than the one

examined in this project

 Census 2006  Explored the possibility to combine change of

land use and increase in property value

 Overall gentrification is present throughout

the area, but more dramatic in the land bought by Concord

 A strong relation between gentrification and

ethnic diversification

 Many improvements can be made to the

project, both ideological and practical
