Officials in Sonoma County struggled Thursday to gauge the local impact of a state Supreme Court ruling that upheld the state’s elimination of redevelopment agencies. Uncertainty remained about the ruling’s implications, especially to redevelopment projects already under way.

The John Stewart Co., which is building a transit-oriented development in Railroad Square, is asking SMART to move the location of affordable housing to an adjacent development. The developer says the shift will make the project financially feasible and could be a catalyst for building in the area. But critics warn the shift may violate state fair-housing laws.
