community resilience goals.
• Develop a seismically resilient pipe net-work.
• Incorporate seismic risk into pipe re-placement
evaluations when identify-ing
and prioritizing pipe replacement
projects.
• Evaluate groundwater facilities to en-sure
operability following a major
earthquake and improve LAFD fire en-gine
and helicopter access.
LADWP will also consider develop-ing
alternate water systems in support
of firefighting such as using the recycled
water system and developing a
pressurized seawater system in areas
along the coast; both of these systems
require feasibility studies. Additionally,
the LAFD and LADWP will investigate
the feasibility of using large- and ultra-large-
diameter hoses, and portable water
supply systems.
LADWP is highly exposed to numer-ous
seismic hazards. The water it supplies
is essential for public health and safety and
for support of both the local economy and
the international commerce facilitated by
the City of Los Angeles. LADWP is imple-menting
a seismic resilience program to
cost-effectively improve its water system
resilience. Key initial steps include fortify-ing
the imported water supplies, creating a
seismically resilient pipe network, increas-ing
local sources, and improving firefight-ing
water supply. S
