BACKGROUND/ANALYSIS
On November 4, 2020, the Financial Advisory Commission (FAC)
recommended approval of Measure G Funding ($404,700) to complete
necessary project improvements for the SilverRock Venue Site and Alongi
Building Projects. The FAC also discussed the proposed SilverRock Venue Site
Project Phase II improvements and prioritization.
42
During this meeting, the FAC requested the formation of an FAC SilverRock
Venue Site Subcommittee (Subcommittee) to further review and provide
recommendations on any future Phase II improvements and appropriation of
Measure G funds. The Subcommittee included Commissioners Dick Mills,
Steven Rosen and Ellen Way. The Subcommittee conducted a site visit of
SilverRock Park and held two review meetings to analyze and discuss the
prioritization of proposed Phase II improvements.
The Subcommittee identified priority improvements and the FAC
recommended appropriation of Measure G funds in the amount of $300,000
at the November 23, 2020 special meeting to complete the following
improvements:
•50 additional shade trees
• Safety fence for outlet structure
•Conversion of irrigation from well and potable water source to canal
water
•Preliminary design for the Soil Stabilization Project
If funding is approved for the preliminary design, a budget for the entirety of
the Soil Stabilization Project will be established and funding appropriation will
be requested once a preferred design is recommended by Staff, reviewed by
the FAC, and approved by City Council. A temporary soil stabilization polymer
will be applied in the interim, while a more permanent solution is identified
and designed. Funding for the cost of the temporary polymer application was
included in the previously approved SilverRock Venue Site Project budget at
the November 17 City Council meeting.
All of the remaining proposed Phase II items are identified as non-high priority
improvements and are recommended to be addressed at a future time.
ALTERNATIVES
Council could elect to modify the improvements funded.
