Livability Analyses(Fine Scale)
Contents• Patterns for Growth• Modeling Growth Scenarios• Rural Bicycle Suitability Mapping• Case Study: Houston, Mississippi
• Rural Growth• What to do when it
happens?• How do we plan for
growth?
Patterns for Growth
Method
Patterns for Growth• Current for rural areas
• New development leapfrogs to greenfields
• No pedestrian connections
• Transportation Efficient Growth• New development is
next to old• Pedestrian/bike
connection
Method
Patterns for Growth• Low Density, Single
Use Zoning• Under 7 dwelling
units per acre• No mixed use• Autocentric
• Higher density, multi-use zoning• 7 dwelling units per
acre and over• Mixed use• Pedestrian
Method
Modeling the Scenarios• Current build-out
of growth• Assumes,
greenfield, low density development
• New pattern of growth• Assumes
development in city core, high density
Method
• CommunityViz• ArcGIS based
software• Allows building of
land-use scenarios
• Can measure impacts such as:• Population• Labor force• Dwelling units• Energy use• Tax revenue
Modeling with CommunityViz
Method
• All commercial and residential properties geocoded
• Zoning and natural hazards are mapped
Modeling with CommunityViz
Method
• Current Build Out• CommunityViz
“builds out” using existing zoning as a guide
• Build out maps produced showing households and density based on continuing existing conditions
Modeling with CommunityViz
Method
• New developments conforming to transportation efficient growth principles are placed in model
Modeling with CommunityViz
Method
• New Build Out• Build out
maps produced showing households and density based on continuing existing conditions
Modeling with CommunityViz
Method
• Identify safe and usable roads for rural cycling• Identify
roads that can easily become bikeways
Bicycle Suitability
Method
• Rural Criteria• Shoulder
width• Traffic
volume• Posted
speed limit• Pavement
surface quality
Bicycle Suitability
Method
• Need easily available data• DOT
• Traffic volume• Posted speed
• Google maps• Shoulder
width• Pavement
conditions• GIS
• Road profile
