Business as Usual
Service rate:
Minimal proactive
repairs and no
proactive
replacement of
assets
Costs:
Cost is $101M
over 20 years with
no funding gap
Risk:
After 20 years,
1/3 of City assets
will be at very
high risk of failure
(currently 1/10)
www.cleanwatersalinas.com
Proposed Service Rate Increase:
Service rate:
Proactively
replace riskiest
assets, and
increase
maintenance and
repairs of others
Costs:
Cost is $237M
over 20 years,
requiring
additional
revenue of
$6.5M/year
Risk:
After 20 years, no
City assets will be
at very high risk of
failure (currently
1/10)
CBP3 2021- G reat opportunity; Leadership change
and lack of SW utility
Urban Greening Grant 2022 - G reen street project at
DAC Park; didn’t want multi-benefit
NOAA Climate Resilience Challenge - L ooking for
regional partnership; not “coastal” enough
CW SRF - P rincipal forgiveness stormwater add -on to currently funded corridor project; Timing challenges
FEMA FMA - L ack of disaster insurance loss claims

CONCLUSION

KION News 46
Data is Power: Map, attribute and model
stormwater system
Focus on multi-benefit project concepts in
DAC areas
Educate and engage city leadership and
peers on the value of better managed
stormwater
Research and understand funding
opportunities and challenges
Work towards a stormwater utility fee
