Build Now Act: how could CDBG funding change?

The Build Now Act (Section 213 of the 21st Century ROAD to Housing Act) ties a CDBG entitlement community's grant to how much housing it is building. This is a CommunityScale estimate from public ACS data, not HUD's official determination — HUD calculates from Census Master Address File block counts.
