From Social Vulnerability and Neighborhood Effects to Planning Knowledge: Tools for Considering Social Equity in Scenario Planning

Robert Goodspeed, AICP Assistant Professor of Urban Planning Presented May 8, 2017 at APA National Planning Conference “Advancing Equity Analysis in Scenario Planning”

Overview

• Project Overview

– Social Vulnerability Tool – Social Equity Tool

• Uncertainty in Scenario Planning Tools

PROJECT OVERVIEW

Equity Analysis Framework

What tools did we create?

• A social vulnerability tool to map out the community before planning has

begun

– The “base map” is typically focused on existing buildings & infrastructure – not social issues

• A neighborhood effects tool to allow ET+ users to conduct additional

analysis of their land use scenarios

– Existing analysis focuses on issues such as fiscal impact and travel behavior

Tool Development Process

Social Vulnerability Index

• Demographics

– Percentage of non-white residents – Percentage of population under age 18 and over age 65

• Social and economic

– Unemployment rate for civilian population in labor force 16 years and over – Percentage of households with no vehicles available

• Wealth and Inequality

– Percentage with income in the past 12 months below poverty level

• Healthcare and Food Access
• Percentage of people without health insurance coverage

– Percentage of population with disability – Food desert status (Yes = 1, No = 0) (more than 1 mile away from the nearest supermarket)

• Education and Language

– Percentage of population with less than regular high school diploma – Percentage of limited English speaking household

• Housing

– Percentage of Vacant housing units – Percentage of households who pay more than 30 % of their income rent – Percentage of renter-occupied housing units

• Large body of descriptive and theoretical work on social vulnerability,

a few validated indices (Lee 2014, Mendes 2009, Cutter et al 2000)

• Created a new index, only 1 correlation greater than .3 at the

individual level!

Neighborhood Effects Tool

• A growing body of “neighborhood effects”

research has documented the role of neighborhoods in various well-being outcomes. Our tool identifies built environment factors in the tool linked to different outcomes. Indicators

• Child BMI (Grafova 2008)

– Proportion of cul-de-sacs

• Adult BMI (Rundel et al 2007)

– Land use mix – Population density

• Collective Efficacy (Cohen, Inahami, Finch 2008)

– Proportion of open space

• Upward mobility, adult BMI, heart disease,

diabetes (Ewing, Meakins and Hamidi 2014)

– Population density – Employment density – Land use mix – Building size mix – Intersection density

UNCERTAINTY IN SCENARIO PLANNING TOOLS

Why care about uncertainty?

In a laboratory experiment a tool which showed uncertainty as a range of values (Dong and Hayes 2012):

• Helped users understand when uncertainty made a choice unclear;
• Helped users make good decisions even with ambiguity;
• Encouraged users to seek clarifying information;
• Was preferred by users!

Only concerns the simplest form of distributional or statistical uncertainty.

What are we uncertain about in planning?

Options Consequences Utility/Value Source: Abbot (2005)

Sources of Uncertainty and Representation Options

Source of Uncertainty Type How to address? Social Vulnerability Tool Index Uncertainty (ACS errors) Distributional Compute margin of error – impossible! Temporal Uncertainty (relevance of past information) Singular Draw attention to years, rates of change Construct Uncertainty (validity of construct) Singular Report empirical validation Neighborhood Effects Tool Factor Uncertainty (Causal- consequences) Distributional Report traditional measures (P values) Strength Uncertainty (Causal-utility) Singular Describe study design; details Temporal Uncertainty (relevance of old studies) Singular Display study years Geographic Uncertainty (relevance of external studies) Singular Provide context comparison

Conclusions

• The adoption of planning tools which utilize external knowledge, introduces

new source of causal uncertainty in planning decisions;

• Most sources of uncertainty are singular and not distributional in nature,

meaning statistical principles do not apply;

• We need improved knowledge about which representations can foster

consideration of these sources of uncertainty in collaborative planning contexts

Multi-dimensional approach to heat planning

• Heat exposure varies within an urban area
• Existing models are too coarse and sensors are few and far between
• Local sensing and downscaled climate models can help
• Sensitivity to heat varies by community/household/individual
• Access to air conditioning, ability to evacuate, etc. may mediate the impact of

heat

• Patterns of sensitivity and exposure to heat may change over time
• Dynamically visualizing, linking, and projecting heat sensitivity and

exposure to create scenarios can be useful for planners

Heat vulnerability framework

Key drivers (sensitivity + adaptive capacity)

Proportion of persons aged 25+ without H.S. diploma Mean household income Female-headed households Proportion of occupied housing units with no car Poverty rate Proportion elderly population Proportion of persons under age of 18 Proportion of population living in group quarters Proportion of population in nursing homes or homes for the aged and dependent Proportion renter households Proportion substandard housing units Proportion of occupied housing units comprised by mobile homes Proportion population identifying as Black or African-American only Proportion population identifying as Asian, Native Hawaiian, or Pacific Islander only Proportion of population identifying as some

• ther race only

Proportion population identifying as Hispanic

• Heat Vulnerability Index
• Captures sensitivity to hazards

across social groups that are attributable in part to the social, economic, political, and institutional factors (Tate et al., 2010).

• Mediates the risk or impact of

disasters (Cutter et al. 2003)

• Developed using a national dataset

and factor analysis technique

Sensitivity + adaptive capacity

Measuring exposure: spatial resolution

Landsat 8

Measuring exposure: temporal resolution

Moderate Resolution Imaging Spectroradiometer (MODIS)

Other data sources

• Open source, web application

– Built in R using leaflet et and shiny packages – Where does vulnerability (higher sensitivity + lower adaptive capacity) intersect with exposure to extreme heat? – Support longitudinal visualization and analysis

• Historical patterns
• Future conditions using downscaled climate model projections and scenario analysis

Tool development

Conclusions and takeaways

• Urban planners and climate action plans need to pay more attention to

extreme heat events (Oke, 2006)

• Land use and the built environment (Stone Jr. & Rodgers, 2001; Coseo & Larsen,

2014)

• Patterns of social vulnerability (Klinenberg, 2015; Reid et al., 2009; Johnson et al.,

2012)

• Data-driven mitigation planning
• We need more tailored and flexible responses
• Where are cooling facilities and capacity given shifting patterns of vulnerability?
• Green infrastructure alongside construction materials alongside social factors

transit corridors

• Aging rental housing likely to be

redeveloped or sold

• Rents in these properties are

likely to rise or units converted to

• wner occupancy
• Aging but unsubsidized rental

housing is typically a city’s largest source of affordable housing Now de demolish shed ed a apa partmen ent bu building (Stoner eridge e Apa partmen ents) s)

Corridor Housing Preservation Tool

A planner’s index for gauging the value and vu vulnerability of affordable housing in transit-served corridors.

Three Fundamental Questions

How many affordable rental units are vulnerable to redevelopment? How much transit access to jobs does a corridor provide to low income residents? How intense is the development pressure?

ADVANCING EQUITY ANALYSIS IN SCENARIO PLANNING Colby Brown, AICP

Alpaca: An Economic Evaluation Plug-in for Scenario Planning Tools

APA National Planning Conference 2017

The Promise of Sustainable Urban Development

• Cities are retrofitting their transportation

networks for a smarter, greener future…

– Fixed-guideway transit (rail, BRT) – Bicycle and pedestrian trails / rights of way – Shared mobility (bike-sharing, ride-sharing)

• The economic value added by these features

can be captured to augment funding streams

– Jobs / economic development – Property value & tax base uplift

Gentrification & Other Challenges

• Planning agencies are being

made increasingly aware of the potential consequences of redevelopment & TOD

• Gentrification of neighborhoods

and displacement of residents moving to top of agenda

• Cities need better models to

predict, prevent and mitigate adverse impacts of plans

How Bid-Rent Analysis Helps

• Robust way to quantify

value uplift from transport projects

• Also predicts

characteristics of

• ccupants

– Example: industry mix – Demographics are more relevant to equity issues

Bid-Rent Demo: LLAMA Web App

• Different market segments have different willingness to pay for

specific real estate property & location characteristics

• Competitive bidding affects “auction” winner & price

68

“Alpaca” vs. LLAMA

“Alpaca” Project Goals

• Integrate bid-rent calculations into scenario planning process

(tools & data) across three distinct, independent case studies:

– MAPC / CommunityViz – FresnoCOG / Envision Tomorrow + – SCAG / Urban Footprint

• Investigate effects of new economic measures enabled by

these tools on planning process
