Upper Oso Dam Danger

The Mission Viejo City Council on Sept. 19 approved Agenda Item 24, allowing high-density housing on the former Kmart commercial site adjacent to the 241Tollway and Los Alisos Blvd. Our council of four members (in the absence of Council Member Gail Reavis) approved the project.

Packing residents into box-like, one-bedroom units with parking problems is bad enough for our city. The real downside is that the units proposed for the site are directly below Oso dam. If you drive up Los Alisos Blvd., you will see that on the other side of the 241Tollway, Oso dam looms ever-present. This is not a concrete dam but an earthen dam similar to the Teton dam in Idaho or Prado dam in Riverside County.

I'm sure that city officials in Driggs, Idaho, and county officials in Riverside County thought their dams would hold up for years to come. It just seems this is not always the case, especially in earthquake-prone Southern California. To build residential units directly below a dam on commercial property that has been rezoned to residential is not a wise decision.
