Goal CR-4

Goal CR-4:

The City minimizes the risk to life and property from seismic activity and geologic hazards in South San Francisco.

Intent:

To lessen the impacts of earthquakes, geologic threats, and other natural disasters on residents, workers, and structures.

Policy CR-4.1: Protect buildings, infrastructure, and other assets from seismic hazards.

Protect existing and new buildings, infrastructure, and other assets from seismic hazards.

  • Action CR-4.1.1: Conduct seismic assessments for municipal assets.

    Regularly complete seismic assessments of critical municipal buildings, facilities, and infrastructure. Develop locally specific seismic hazard maps to improve mapping resolution and support more informed and nuanced decision-making about development and hazard mitigation, particularly where other hazards like sea level rise compound the risk.

  • Action CR-4.1.2: Continually update the Building Code for seismic and other hazard safety.

    Regularly update the City’s Building Code to incorporate current earthquake standards.

  • Action CR-4.1.3: Maintain a soft-story buildings inventory.

    Maintain and regularly update a database of soft story / fragile housing.

  • Action CR-4.1.4: Expand seismic retrofit incentive program expansion.

    Expand efforts to incentivize retrofits of buildings and other mitigation measures in seismic and geologic hazards zones. Explore developing a specific program to address seismic retrofit needs within South San Francisco’s affordable housing stock.

Policy CR-4.2: Maintain emergency response capabilities.

Maintain the capability to quickly respond to natural and human caused disasters and minimize damage and injury caused by these events.

Policy CR-4.3: Discourage hillside area development on slopes more than 30 percent.

Discourage development on steep hillside areas more than 30 percent grade. Development of hillside sites should follow existing contours to the greatest extent possible. Grading should be kept to a minimum.

Policy CR-4.4: Protect buildings, infrastructure, and other assets from other geologic hazards.

Protect existing and new buildings, infrastructure, and other assets from other geologic hazards, including landslides, slope instability, liquefaction, settlement, subsidence, unstable geologic units, unstable soils, and expansive soils.

  • Action CR-4.4.1: Require site-specific soils and geologic reports for projects located in high-hazard areas.

    On a parcel-by-parcel basis, require that permit applications for projects located within areas susceptible to geologic hazards, as shown on Figure XX, prepare site-specific soils and geologic reports for review and approval by the City Engineer, and incorporation of the recommended actions during construction.
