Creeks and rainfall on the city record

A city environmental report describes FEMA flooding along Serrano Creek in Zone AO with 100-year depths of 1 to 3 feet, Aliso Creek as a designated floodway along the eastern boundary and Borrego Canyon Wash in Zone A. The report says mean annual rainfall is about 15 inches and 87 percent falls from November through March. It notes that most local channels are channelized.

The report was written about a project area, so use it as context and not as a map of your street. Check the FEMA flood map for your address, and read about flood damage restoration if storm water has already entered a garage or lower level.

When water is spreading in Lake Forest

Water is an emergency when it is still running, when it touches outlets or a panel or when it reaches more than one room. Call the 24/7 line, and the dispatcher will tell you what to shut off. Same-day response is offered when available.

• Stop the source

  Close the main water valve or the valve at the fixture. If the supply line is in a condo wall, tell the HOA so shared water can be shut off.

• Power safety

  Turn off power to wet rooms only if the panel is dry and you can reach it without standing in water. Call 911 or your utility for any electrical or gas risk.

• Lift and photograph

  Move electronics and small furniture away from wet areas and take photos of the water line before anything is moved.

• Keep people out

  Keep children and pets out of any water that came from a toilet, drain or sewer, then call the 24/7 line for Lake Forest.

Who supplies water and sewer in Lake Forest

The city environmental report says Irvine Ranch Water District is the primary provider, with Trabuco Canyon Water District serving a small northern area and El Toro Water District serving the southeast corner. Santa Margarita Water District owns a trunk line near Glenn Ranch Road and El Toro Road but does not provide service in the city. Sewer service is provided by IRWD through the Los Alisos Water Reclamation Plant.

The assignment for Foothill Ranch and Portola Hills was not found, so check your bill. If a main valve fails or a sewer line backs up, your district is the first call after 911 for any safety risk.
