CoreLogic has estimated that 5,895 azygous and multifamily residential properties pinch a mixed reconstruction worth (RCV) of $2.88 cardinal are astatine consequence of flooding pursuing nan Pajaro River successful Central California overflowing its levee.
On March 10, nan h2o level successful nan Pajaro River surpassed its levee, starring to a breach and a partial illness that resulted successful nan flooding of homes and cultivation lands successful Pajaro and Watsonville, California.

The patient notes that historically, Pajaro and Watsonville person been protected by earthen levees connected nan near and correct banks of nan Pajaro River, which were constructed successful 1949, arsenic per nan U.S. Army Corp of Engineers National Levee Database.
The levees person been tested connected respective occasions since construction, having only grounded erstwhile owed to flooding successful 1995. However, during each test, important slope erosion occurred. In 1995, floodwaters seeped done nan levee, causing erosion of nan sides and yet flowing complete nan levee.
