City of Houston Proposition B would require the city to leave H-GAC unless the regional body grants Houston proportional representation on its governing board.
If voters approve the charter, the city would have 60 days to negotiate with H-GAC, if not, Houston would be required to pull itself out of the council.
The 37-member board of directors for the H-GAC, which allocates federal, state and local funding for the 13-county region, includes only two members from Houston.
