IntroductionUrban Tree Canopy and Socio-Economic

Benefits:◦ Carbon sequestration◦ Reduce Storm Water Runoff◦ Energy Reduction◦ Higher Quality of Life◦ Less $$

Benefits of our study◦ COA legislative decisions◦ Green future that is economically feasible for Austin, TX

Primary Areas of StudyPavement Conditions

◦Less maintenance = less cost

Crime rates◦Lower crime = less costs and happy

citizens

Property values◦Higher property value = higher

property taxes and affluent citizens

ScopeCharacteristics within the City of Austin that will be focused on:

1. Heavy tree cover

2. Broad tree cover

3. Average tree cover

4. Limited tree cover

5. No tree cover

Pavement Costs ResearchPavement Costs for the City of Austin2010: $42,571,6742011: $50,163,1352012: $37,186,628(Wilson 2012)

Modesto, CA◦Over a 30-year period, up to 60% savings in

pavement maintenance and rehabilitation cost

(McPherson & Muchnick, 2005)

Property Values ResearchTwin Cities

◦Increasing tree cover w/in 250 meters = 60% gain in home sale prices

Comparison Model◦How do external factors relate?

(Sander 2010)

Crime Rates researchBaltimore

◦Strong negative relationship

Portland◦Moderately negative in old growth

forests(Donovan, Prestemon, 2010)

DataCity of Austin GIS data sets

MethodologyObjective 1 – Pavement Costs

◦External factors: Age, traffic, environment, material,

strength of pavement

◦Comparative analysis Model based on natural effect of external

factors How does this relate to tree cover?

◦Expect positive correlation

MethodologyObjective 2 – Crime rates

◦External factors: Median income, age of neighborhood, prevalence of

alarm systems, sidewalk traffic, and single family homes

◦Crime to be measured: Home invasion, burglary, auto theft, vandalism

◦Comparative analysis Model based on natural effect of external factors How does this relate to tree cover?

◦Expect negative correlation

MethodologyObjective 3 – Property Value

◦External factors: Environmental, Structural, Community

◦Comparative analysis Model based on natural effect of external factors How does this relate to tree cover?

◦Expect positive correlation
