Safety

The City of Thousand Oaks is committed to protecting the community from natural and human-induced hazards and building resilience to projected climate change risks. This Element describes these hazards and establishes goals and policies to protect people, property, and the natural environment.

Goals and Policies

Faulting and Seismic Hazards

S-1.1 Geologic and engineering investigations.
Require site-specific geologic and engineering investigations as specified in the California Building Code (as adopted by the State of California with local amendments) and Municipal Code for proposed new developments.

S-1.2 Earthquake resistant design.
Enforce the latest California Building Code (CBC) provisions relating to earthquake resistant design.

S-1.3 Strong motion instrumental program fund.
Continue to allocate a percentage of building permit fees (as specified in the Public Resources Code) to a trust fund (Strong Motion Instrumentation Program Fund) which is remitted to the State of California.

S-1.4 Setback distances.
Provide setbacks, as determined to be necessary, for any proposed development located on or near an active or potentially active fault. Appropriate setback distances will be determined through engineering geologic investigation.

S-1.5 Notice of geologic hazards.
Require all developers and/or subdividers of a parcel or parcels in an area of a known fault hazard to record a Notice of Geologic Hazards with the County Recorder describing the hazards on the parcel and the level of prior geologic investigation conducted.

S-1.6 Faulting/seismic hazards.
Require hazard mitigation, project redesign, elimination of building sites, and the delineation of building envelopes, building setbacks and foundation requirements, as deemed necessary, to minimize faulting/ seismic hazards for new development and redevelopment.

S-1.7 Seismic retrofitting.
Investigate options for seismic retrofitting of older buildings that do not meet current seismic standards.

Landslides and Debris Flows

S-2.1 Setbacks from debris flow.
Require all development to provide setbacks from potentially unstable areas, including potential debris flow channels, as identified in engineering and geologic studies.

S-2.2 Drainage plans.
Require new projects to prepare drainage plans designed to direct runoff away from unstable areas.

S-2.3 Surface runoff in unstable areas.
Discourage introduction of surface runoff, including nuisance water into the ground, where the area is unstable.

S-2.4 Road reconstruction.
Where washouts or landslides have occurred on public or private roads, require road reconstruction to meet the conditions of geologic and engineering reports.

S-2.5 Building in flowline.
Discourage development in the flowline or discharge areas of hillside swales or channels.

S-2.6 Notice of geologic hazards.
In areas of known slope instability or debris flow hazards, require developers and/or subdividers of a parcel or parcels to record a Notice of Geologic Hazards with the County Recorder describing the potential hazards on the parcel and the level of prior geologic investigation conducted.

Soil Hazards

S-3.1 Liquefaction.
Require developers to submit studies that evaluate liquefaction potential for proposed developments in areas susceptible to liquefaction as illustrated by Figure 10.3.

S-3.2 Liquefaction hazard risk.
Require project alterations and/or mitigation as necessary to remediate liquefaction hazard risk.

S-3.3 Notice of geologic hazards.
Require developers and/or subdividers of a parcel or parcels in areas susceptible to liquefaction or of known highly expansive soils hazard to record a Notice of Geologic Hazards with the County Recorder describing the potential hazards on the parcel and the level of prior geologic investigation conducted unless the condition has been mitigated.

S-3.4 Soils reports.
Require the preparation of a soils report, prepared by a registered civil engineer, for developments where soils have been identified that are subject to expansion, or where there is inadequate soils information.

S-3.5 Hazard mitigation for soil hazards.
Require hazard mitigation, as necessary, to mitigate hazards associated with soils that may be subject to expansion, or settlement.

Flood Hazards

S-4.1 New development in flood zones.
Require new development in flood zones and dam inundation areas to minimize flood potential and ensure that development siting and design features will not increase flood inundation potential offsite. Regulate filing, grading, dredging, and other development that may increase flood damage.

S-4.2 New essential facilities in flood zone.
Prohibit the siting and construction of new essential public facilities within flood hazard zones, when feasible. If an essential facility must be located within a flood hazard zone, incorporate flood mitigation to the greatest extent practicable.

S-4.7 Floodplain improvements.
Partner with the Ventura County Watershed Protection District to complete drainage improvements to enable parcels to be removed from the 100-year floodplain.

S-4.8 Flood control.
Protect and maintain natural hydrological and ecological functions by implementing flood control improvements that use natural materials when possible. If the use of natural materials is not feasible, select the most environmentally preferred option and limit concrete channelization to the extent possible.
