Due to storm damage Contra Costa County issues Proclamation of Local Emergency

Thursday, January 19th, 2017

Contra Costa County Administrator David Twa on Thursday, January 19, 2017, signed a proclamation of local emergency in response to winter storm damage that has occurred in a variety of locations throughout the unincorporated parts of the County. The local emergency declaration will be presented to the Board of Supervisors for ratification in a special meeting scheduled for Thursday, January 26, at 8:30 a.m. The emergency status enables the County to be eligible for disaster relief funding that might be available in the future.

The strong series of storms has led to widespread flooding, mudslides, sinkholes and damage to public buildings, flood control facilities and roadways. Notably, Alhambra Valley Road remains closed between Bear Creek and Castro Ranch Roads. Signs and message boards remain in place to alert drivers; there is no estimate yet on a date for reopening Alhambra Valley Road.

Morgan Territory Road remains open only to local traffic between Marsh Creek and Manning Roads, with the goal of reopening entirely next week.

Some county roads reopened, Morgan Territory Road anticipated to reopen next week

Thursday, January 19th, 2017

Contra Costa County has reopened the following roads:

  • Marsh Creek Road between the Clayton city limits and Deer Valley Road
  • McEwen Road between Highway 4 and Carquinez Scenic Drive

The following road is open to local traffic only:

  • Morgan Territory Road between Marsh Creek Road and Manning Road is anticipated to reopen the week of January 23-30

The closures were required due to mudslides and flooding concerns. The amount of rain received has saturated the soil which makes it more difficult to remove the mudslides and clean the roadways. Alhambra Valley Road between Bear Creek Road and Castro Ranch Road is closed indefinitely. Signs and message boards will alert drivers of the closure. There is not an estimated timeframe for reopening Alhambra Valley Road at this time. Drivers are encouraged to use the routes on the map below as alternate routes for Alhambra Valley Road.
