Windy with periods of rain. Potential for heavy rainfall. Low around 55F. Winds S at 25 to 35 mph. Chance of rain 100%. Rainfall near a quarter of an inch.
The Federal Emergency Management Agency is requiring Foster City to spend $75 million to raise their levees so that the city won’t be declared a flood zone. Such a designation would make it necessary for homes in Foster City with mortgages insured by a federal agency to acquire flood insurance. I’ve seen nothing that tells me how many such homes there are, but I would venture that there are very few. I’ve also seen nothing regarding the cost of the insurance. Since Foster City has been well-protected from floods by a system that has proved itself for over 50 years, I can’t imagine that such insurance is very expensive. So raising the levees would only save a few people from paying that insurance, at the cost of $75 million from homeowners.
Flooding has been the single biggest issue impacting the infrastructure of the city since the beginning. Not because of flooding from the Bay, since the levees have been in place since 1900. Rather, the problem was that the levees helped to trap the rainwater that fell on the land. The county’s engineer was concerned enough that he suggested the fill of the land should be raised high enough that rainwater would drain directly into the Bay. Aside from the economics of this idea, it was physically impossible. The soft underlying soil would not be able to support the weight of the fill.
The solution that was finally implemented was the lagoon system, which collects the rainwater, which then pumps out to the Bay when needed during rainy seasons. The holding basin of the system can hold over an inch of rain, though the pumps work as the rain falls.
This is the system which exists in FEMA’s so-called “flood zone.” FEMA’s fear comes from a potential rise in water levels of the Bay. At its current rate of increase, about 1 inch per decade, the need to deal with this matter is years away. When we do need to deal with it, it will be at high tide only, and only in small quantities of water. This water will run into the storm drain system and into the lagoon, where the pumping system will take care of excess water. Certainly, it is possible that this system can be overwhelmed by too much water. Good notice of this will be provided as the issue evolves, and we can raise the levees at that time, with a better view of the extent of the work needed.
