Item 1.01.  Entry into a Material Definitive Agreement.

     On June 1, 2006, the Executive Compensation Committee of
the Board of Directors of SJW Corp. (the "Company") approved
certain amendments to the Company's Deferred Restricted Stock
Program (the "Program").  The Program is administered as part of
the Company's Long-Term Incentive Plan and provides a series of
annual deferred restricted stock awards to non-employee
directors who first join the Board on or after the date of the
2003 annual shareholders meeting.  Pursuant to such amendments,
the grant date for those annual awards will be modified,
effective January 2, 2007, as follows:  (i) the initial award to
a newly elected or appointed non-employee director will be made
on the first business day in January (instead of following an
annual meeting of shareholders) next following his or her
completion of at least six (6) months of Board service and (ii)
annual awards to continuing non-employee directors will be made
on the first business day of January (instead of following an
annual meeting of shareholders) in each of the next nine (9)
calendar years of their continued Board service.  The amendments
also bring the Program into compliance with the applicable
requirements of Section 409A of the Internal Revenue Code and
the proposed Treasury Regulations thereunder.  A copy of the
Program is attached hereto as Exhibit 10.1.

Item 7.01  Regulation FD.

     SJW Corp. filed a press release to announce that the
purchase of the assets of Canyon Lake Water Supply Corporation,
a Texas non-profit water supply corporation, by SJWTX Water,
Inc., closed on May 31, 2006.  SJWTX Water, Inc., a newly formed
