Re: [californiadisasters] ] On This Date In CA Weather History (September 30)- Laguna Fire


Thanks for the great post.... in theory it could happen as soon as next week when Southern California experiences its first Santa Ana Wind event of Autumn 2010.

Here is some information about the Laguna 1970 fire in San Diego county.

The Laguna fire of 1970 ringed the outskirts of El Cajon.  We watched as homes went down on the ridges on the Southern section of El Cajon Valley. Crest is a ridgetop to the east of El Cajon Valley.  It is part of the Bostonia Postal Service area.  Many of the homes destroyed were in Crest.  It actually was a faster moving fire than Cedar.  It moved into Crest from the same area of Wildcat Canyon-Putz Valley as in Cedar 2003.  It also had a secondary front that is reputed to have had fire moving at 55-60 miles per hour in Dehesa Valley.(this is where I live now)  Dehesa is due west of Kitchen Creek, where the fire started.  More of Dehesa and El Cajon were burned in 1970.  The fires into the Southern El Cajon section came from the Dehesa Valley. The fire did not stop moving west until La Presa.  The only thing that stopped this fire from continuing to the west was a weather change.

here is information about this fire. 

Here is a map of Cedar 2003.  In some ways, specifically in the speed of the fire, Cedar was nothing compared to Laguna 1970.  Laguna was truly unstoppable, because of the 55-60 mile an hour winds.  Thank the weather for it not burning to the ocean and down the Sweetwater river to Chula Vista.

Here is a pdf document that gives a list of recommendations for controlling fire in this area.  Note the recommendation for undergrounding power lines.  In addition we had trouble with communication between the different responders, just like in Cedar.  They have not fixed this yet, and SDG&E has not undergrounded some of the most critical areas as recommended.

It IS going to happen again.
