Santa Anita Fire - 4/26/08

Less than 3% of the predicted ten year storm mud-flow is expected to come from the One Carter property, some of which was denuded by fire, and some by the developer.  So the development at One Carter was also a (minor) contributing factor to the potential mud and debris flow problems the City is facing.

Phase II = Moderate debris and mudflows possible at more widespread locations.  Some streets may be completely blocked by debris.  Depending on location and terrain, some structures may be endangered by debris and mudflows.

Phase III = The potential exists for significant debris and mudflows to be widespread over specific areas.  Streets may be blocked and considered unsafe for travel.  Many structures could be endangered by debris and mudflows.  Extreme caution should be exercised below uncontrolled canyons due to sudden debris and mudflows.
