The Sonoma County Board of Supervisors returns to two controversial issues on Tuesday: The beleaguered condition of county roads and a proposed cap on marijuana dispensaries.

The roads discussion is set to focus on options for increasing county support for the 1,382-mile network. Budget-saving moves last year and in 2010 reduced long-term maintenance to just 16 percent of the network.

The afternoon discussion on dispensaries will center on a proposed cap of nine medical marijuana shops in unincorporated areas.

There currently are six permitted dispensaries under county oversight and another three pending applications.
