* All billed materials and work conducted prior to the CWCB grant purchase order will be paid by the District as a
portion of their match.

The District plans to complete the set up and begin operations of the Phase II equipment
in July 2008. Originally it was anticipated that this would be completed at the beginning
of the 2008 irrigation season where a complete set of irrigation data would be available to
estimate water savings and develop the final completion report. The District plans to
defer the final completion report until the end of the 2009 irrigation season when a full
set of irrigation data would be available for analysis.

Goals and Objectives
The District has met their goals and objectives for the Phase I installation. The
equipment was successfully installed. As previously indicated, weather and budgetary
constraints have impacted the remainder of the project schedule. The District has revised
the project schedule as indicated in Table 1.

Preliminary Findings and Obstacles
The installation of the irrigation management system equipment was achieved as
planned and no major obstacles were encountered. However, the District encountered
several challenges with the operational set up of the central control station,
communications system, and the weather station.

· Central control station: The District experienced difficulty in programming the
central control station computer. Remote assistance from the CALSENSE
contractor did not prove to be sufficient and a CALSENSE technician had to be
brought in to address the programming issues onsite.
