Alternative 2 will provide the following user involvement and training tasks and programs:
• On -line web -based training modules for HydroBase, StateView, CWRAT, StateMod,
StateCU and the groundwater model
• Database of contacts for system users together with a point of contact for
communication
• Newsletters four times per year which discuss the status of the project and advertise
upcoming meetings
• SPDSS advisory committee meetings twice a year
• Technical subcommittee meetings throughout development of the project
• SPDSS core group meetings twice a year
• Four user group meetings per year to provide a mechanism for communication of
technical topics
COSTS AND SCHEDULE
Estimated costs for each of the three SPDSS alternatives range from $10.3 to $33.3 million
dollars as follows:
• Alternative 1: $10.3 million
• Alternative 2: $15.0 million
• Alternative 3: $33.3 million
Estimated costs to develop and implement the most cost effective and efficient alternative is the
recommended SPDSS alternative (Alternative 2) at approximately $15.0 million. This includes
$5.65 million (38 percent) for data collection, $6.97 million (46 percent) for development of
components and $2.37 million (16 percent) for technical review and project management
assistance, consultant coordination, and some aspects of user involvement. The SPDSS will be
funded in the same manner as the CRDSS and RGDSS projects, from the CWCB's Construction
Fund on a non - reimbursable basis. This is a self - generating funding source that will not result in
a tax increase.
Efforts will be made to enter into cooperative agreements with the USGS and other agencies in
order to reduce total project costs. Cooperative agreements will focus on data collection
activities.
The recommended SPDSS alternative is anticipated to be developed over a six -year period in
three phases as follows:
• Phase 1 is expected to require approximately two years and will focus on data collection
and water administration tools. Certain data collection activities, such as groundwater
levels and streamflow gaging, will continue through and beyond SPDS S implementation.
