Item 2.06  Material Impairments.

SJW Land Company, the registrant's wholly owned subsidiary, entered
into an option agreement dated December 3, 2010 for the sale of its
three hundred sixty-one thousand five hundred (361,500) square foot
distribution facility located in Knoxville, Tennessee and approximately
30 acres of land on which such building is located for sixteen million
five hundred thousand dollars ($16,500,000).  The right to exercise the
option terminates on June 1, 2011.

On December 6, 2010, the registrant determined that signing the option
agreement represents a change in circumstances in the intended use of
such building and land and, concluded that its current carrying value is
not recoverable.  As a result, the registrant will recognize a pre-tax
impairment loss on the building and land in the 2010 fourth quarter in
the range of $2,700,000 to $3,100,000, which includes estimated selling
costs in the range of $700,000 to $1,000,000.
