Introduction
Lee CountyFort Myers
Florida
Study Area:Downtown Historic and River Districts

IntroductionUrban redevelopment: 54-block utilities and streetscape $60 million ($12.5 million streetscape) International award 5 state awards
Project Objectives: Rate the walkability of the redevelopment
area of downtown Ft. Myers
1. Identify a measurement tool2. Measure walkability3. Validate the tool
Develop Hypothesis:
The measurement tool is substantiated by the variable quality of the built environment

NEWS – Neighborhood Environment Walkability Survey
SPACES – Systematic Pedestrian and Cycling Environment Scan
PEDS – Pedestrian Environment Data Scan
Irving-Minnesota Inventory
Active Living Research (ALR) Audit Tool
A. Determine spatial assessment toolB. Identify evaluation segmentsC. Implement the assessment tool D. Spatial analysis

Methodology

street segment: about one block inlength, 300 feet or about 120 paces
Proposed Approach
B. Identify evaluation segments Select 9 street segments Subjective observations High, Medium, Low quality
C. Implement the assessment tool ALR Audit Tool Objective measurements
A. Determine spatial assessment tool Subjective/objective ALR Audit Tool
D. Spatial analysis Overall walkability scores Urban design qualities ALR Tool validation
22
Methodology
(Park and Kang, 2011)
D. Spatial analysis Overall walkability scores Urban design qualities ALR Tool validation
This diagram by Park and Kang (2011) iswhat I have in mind to show the walkabilityratings. Color-coded segments would indicate the values of the five urban qualitieseach mapped separately for analysis.
