Coldwater Canyon Closure Starts Saturday

Motorists were reminded again Wednesday that Coldwater Canyon Avenue will shut down for a month starting Saturday so city crews can perform a major construction project to replace a 100-year-old water main.

The work will be done between Ventura Boulevard and Mulholland Drive on the route that is one of the major alternatives for residents to cross from the San Fernando Valley into the Los Angeles basin. Some 1,300 cars per hour will need to find other routes.

"This is a vitally important project to ensure the continued safety and reliability of our drinking water," Councilman Paul Krekorian said. "I know how difficult it will be to drive through the area during this time, which is why I would urge all of us to find alternate routes during construction. "

Krekorian said his staff will work with residents, businesses, schools and motorists to make sure they are kept informed of the status of the project.

The work on the $62 million project is scheduled to begin Saturday and last through April 26. The street will be closed to traffic from 8:30 a.m. to 7 p.m. Mondays through Fridays and from 8:30 a.m. to 6 p.m. on Saturdays.

During overnight hours and on Sundays, one lane in each direction will be open.

Residents will be provided special access passes allowing them access so they can get to their homes.

DWP officials said the shutdown of the street is needed because of the narrow road conditions and the amount of heavy equipment needed to excavate the road, remove and replace the 60-inch pipe.

The DWP planned the project to occur before the summer months when water use is the highest, officials said.

In 2009, a water line ruptured at Coldwater Canyon and Ventura Boulevard, causing extensive flooding of residences and businesses, with repairs costing more than $700,000 and claims of more than $8 million filed against the city. An estimated 4 million gallons of water was lost. ___
