One of the wettest Decembers in recent San Diego history could lead to mud and landslides in the County, according to both the U.S. Geological Survey and local Geologists.  A number of slides have already occurred in the County, most notably in the coastal bluff areas, and in the College area.  Geologists warn that the effects of the rain might not be felt for several weeks or months.  The unusual amount of water can take some time to penetrate into the ground, and the danger of future soil slippage will be present throughout the coming months.  Indicators of potential slides include the following:

     1.  Cracking or bulging in the ground, street, or sidewalks.

     2.  New cracks in walls or foundations.

     3.  Sticking doors and windows, indicating that they are out of plumb.

     4.  Movement of soil away from building foundations.

     Residents are warned that water adds significant weight to soil, and that when the soil is saturated, it is particular vulnerable to moving or giving way.
