What is Hazard Mitigation?

2 | Cabrillo College November 4, 2019

Mitigation is any sustained action taken to reduce long-term risk to life and property from a hazard event

Hazard Profiles


Example: Liquefaction – Location and Extent

11 | Cabrillo College HMP July 24, 2019

Both the Aptos and Watsonville Campuses fall within Liquefaction Hazard Areas

Presenter

Presentation Notes

Liquefaction is the transformation of loose, water-saturated granular materials (such as sand or silt) from a solid to a liquid state. Liquefaction commonly, but not always, leads to ground failure. Liquefaction potential varies significantly and site-specific analysis is needed to accurately determine liquefaction potential in earthquake prone areas. For the purposes of this meeting, we are treating this the same as earthquake – same mitigation actions.

Flood


National Flood Hazard Layers from FEMA show the Watsonville campus within the Special Flood Hazard Area

Presenter

Presentation Notes

The Pajaro River flows through downtown Watsonville, causing flood risk. SFHA are defined as the area that will be inundated by the flood event having a 1-percent chance of being equaled or exceeded in any given year. Zone AH Areas subject to inundation by 1-percent-annual-chance shallow flooding (usually areas of ponding) where average depths are between one and three feet. Base Flood Elevations determined. Flood elevation: 32 feet Ground elevation: 36 feet (10 meter resolution)

Example: Flood Vulnerability


Hazard Ranking: • Flood Zone• Construction Date and Type• Foundation Type• Lowest Point of Entry• Building Height• Contents Value Below Flood Depth

Vulnerability: • Hazard Ranking• Building Criticality

Presenter

Presentation Notes

HR: Watsonville B has the most risk because of the basement, oldest building, and construction type. A and D are the lowest because of construction type and contents below BFE. Vulnerability: All buildings have the same criticality level, which evens out the vulnerability map (brings up the lower hazard rankings, because all the buildings are important).

Example: Flood Loss Estimates


Building Name Total Losses* from 1 ft of Flooding

Watsonville Building A $528,026

Watsonville Building B $1,482,738

Watsonville Building C $893,180

Watsonville Building D $2,147,655

*Total Losses include losses to the building and its contents, as well as from loss of function.

LOF Cost = Square Footage Factor x [(Annual College Budget / 365 days) x Estimated Days with LOF]Where: Square Footage Factor = (Building Square Footage x Building Criticality Score) / Total Factored Campus Square Footage)

Presenter

Presentation Notes

A has the lowest losses because it is elevated 4 feet above grade B has relatively high losses because it has a basement that will flood, but not the highest because its first floor is elevated 4 feet about grade as well C and D are both at grade, so the difference in losses is driven by difference in value of the building and it’s contents

Fire


Neither campus falls within Fire High Hazard Areas, but Cabrillo does have a significant risk from fire.

Presenter

Presentation Notes

Wildfire Hazard Areas: Large areas of the County have been mapped as Critical Wildfire Hazard Areas due to accumulations of wildfire prone vegetation, steep and dry slopes and the presence of structures vulnerable to wildland fires. These areas are generally situated in the steeper higher elevations of the county. While the map of Critical Fire Hazard Areas remains relevant for areas of increased wildfire risk, it should be noted that wildland fires may occur anywhere within the planning area.

Example: Fire Hazard Ranking


Hazard Ranking: • Construction Date and Type• Exterior Construction Type• Roof Type• Fire Protection• Contents Type• Tree Cover/Vegetation• Topography

Presenter

Presentation Notes

HR: Fire Protection is the most heavily weighted, and drives the HR. Proximity to vegetation is also apparent. Watsonville D is at a higher risk because of exterior construction and roof type.

Example: Fire Vulnerability


Vulnerability: • Hazard Ranking• Building Criticality

Presenter

Presentation Notes

Criticality makes the buildings that are more important show higher vulnerability

Example: Fire Loss Estimates


Loss Estimates: • Building Loss• Contents Loss • Loss of Function Cost

LOF Cost = Square Footage Factor x [(Annual College Budget / 365 days) x Estimated Days with LOF]Where: Square Footage Factor = (Building Square Footage x Building Criticality Score) / Total Factored Campus Square Footage)

Presenter

Presentation Notes

Building and content loss is on a percent scale based on the Hazard Ranking. 1 = 5%, 2 = 10%, 3 = 25%, 4 = 50%, and 5 = 100% Criticality is only considered within the loss of function costs. Based on the hazard ranking and how expensive the building is.

The Watsonville Campus is shown as being in a FEMA 100-year (1% Annual Chance) floodplain with an AH designation. The flood elevation is shown as elevation 32 NAVD. The ground elevation in the vicinity of the buildings appears to be approximately elevation 36.

Action-Flood 1: - Obtain a FEMA Elevation Certificate for each building and apply for a Letter of Map Amendment to remove the campus from the designated flood zone Regulatory Flood

The pedestrian bridge over Soquel Drive is the main form of movement between the upper and lower campus areas. It is considered a critical unit of campus infrastructure. Loss, or rendering unsafe, as a result of an earthquake would hinder the operations of the campus

Action-EQ 1: a) Obtain an analysis of the bridge for structural integrity and earthquake resilience by a qualified structural engineer b) Undertake retrofit options to improve the safety and resilience of the bridge.
