Planning Ahead for Livable Communities Along the Powell-Division BRT: Neighborhood Conditions and Change

New transit investments can be a double-edged sword for disadvantaged communities (e.g. those included in environmental justice and Title VI potected classes). Transit investments improve community’s mobility and access and may improve health with reduced driving nearby. However, there is also the potential for transit-oriented development to spur gentrification and displacement if affordable housing is lost.
Understanding transit corridor conditions and change with new infrastructure is ...
