 > ```(Chapters 12-14, pgs.255-308)```
 
 > ## Terms:
->> ```Liveability```: All the characteristics of a community that contributes to the quality of life of the people who live there

 > ## Urban Issues
 >> ```Urban Sprawl```: largely uncontrolled expanision of cities onto adjacent or rural lands      
 
 >> ### Urban Sprawl Impacts

->>> Plannign for mass transit

+
+>> ### Solutions
+>> - HOV lanes: high occupancy vehicle lanes available to buses and passenger vehicles carry at least two people; designed to help move more people through congested areas
+
+>> - Waste Management: extensive recyling and composting programs (ex. Ontario's blue box)
+>> - Smart Growth: A concept for urban exapansion that also preserves the natural environment
+>>   - Principles
+>>     - Develop in existing communities
+>>       - Make them compact instead of sprawling out
+>>     - Mix land uses
+>>       - Put homes stores, offices, and services in close proximity to reduce traffic, and increase walking / biking
+>>     - Create a range of housing opportunities
+>>       - Bring people of different ages, household types, incomes, ethnicities together
+>>     - Provide variety of transport choices
+>>       - Public transit
+>>     - Create places and routes for safe walking / biking
+>>     - Protect wildlife habitats
+>>       - natural corridors
