October 19-26 is California Flood Preparedness Week. It's time to... 

Be Aware! Be Prepared! Take Action!

1. Be Aware of your Risk
  • Know whether your home is in a flood zone and what type of flooding is likely in your area.
2. Be Prepared
  • Make a flood emergency kit. This includes a list of important phone numbers, medication, flash light, batteries and a radio.
  • Make an evacuation plan. If your community is flooding, you may not be able to drive on your usual roads.
  • Make a plan to communicate with family members if you should leave home.
  • Check into the national flood insurance program. Most homeowner’s insurance policies don’t cover this type of flooding.
3. Take Action
  • If your community is flooding:
    • Stay informed by listening to the news
  • Always evacuate if you are directed to do so. Help may not be able to get to you later if you stay home.
  • Never try to drive through a flooded street. Just 6” of water can stall or float most cars. If you can’t drive out, get to the highest area in your home or building.
  • Know where to obtain sandbags to protect your home and property. Local resources can be found here.

Preliminary Lake Use Evaluation for the Chain of Lakes (2014)

The purposes of this 2014 study are to identify which potential lake uses may be more suitable for individual former quarries – especially where conflicting proposed alternatives uses may exist – and provide a framework for evaluating proposed uses as lakes are transferred to Zone 7 ownership. The evaluation generally does not preclude any given lake from distinct uses, but instead provides a tool for examining the benefits or impacts associated with a proposed use.
