New structures are required to adhere to current California Uniform Building Code (CUBC) standards. (Top) In the Planning Area, hazards due to ground shaking are considered to be low. Damage is most likely to occur to older masonry buildings. (Bottom) 8-4 VISALIA GENERAL PLAN UPDATE earthquakes, slip rates on major faults and deformation throughout the region and the potential for amplification of seismic waves by near-surface geologic materials. The resulting earthquake shaking potential is used in developing building code design values, estimating future earthquake losses and prioritizing earthquake retrofit. In the Planning Area, low levels of shaking, with less frequency, are expected to damage only weaker masonry buildings. However, very infrequent earthquakes could still cause strong shaking. 3 Ground Failure Earthquake-induced ground failures, such as ruptures, lateral spreading, ground lurching, seiches, or mudslides, are unlikely to occur in the Planning Area because of its relatively stable geologic formation and lack of active faults. 3 California Geological Survey and US Geological Survey, Earthquake Shaking Potential for California, Map Sheet 48 Revised 2008). 2008. http://www.conservation.ca.gov/cgs/ information/publications/ms/Documents/MS48_revised.pdf Seismic Safety Existing structures in the Planning Area could be affected by the types of earthquake-induced effects listed above, but to varying degrees based on length, intensity, and distance of the earthquake from a given building. New structures are required to adhere to current California Uniform Building Code (CUBC) standards for Seismic Zone 3, providingand provide adequate design, construction and maintenance of structures to prevent exposure of people and structures to major geologic hazards. In particular, any critical facilities such as hospitals, fire and police stations, and emergency communications and operations centers must be adequately designed, constructed and maintained with the goal of remaining functional after a large seismic event. The use of flexible utility connections, building anchors, and adequately reinforced concrete can reduce the loss of life and damage to buildings for human occupancy.
Objectives S-O-1 Minimize risks of property damage and personal injury posed by geologic and seismic hazards. Policies S-P-1 *Work with Caltrans to seismically retrofit or replace local ramps and freeway overpass bridges that are categorized as structurally deficient by Caltrans, are located in high ground shaking areas, and/or are necessary for first responders to use during and/ or immediately after a disaster or emergency. S-P-2 *Seismically retrofit or replace public works and/or emergency response facilities that are necessary during and/or immediately after a disaster or emergency. S-P-3 *Update the City’s Emergency Preparedness Plan to include an Earthquake Disaster Plan, and coordinate procedures with the County Emergency Services. S-P-4 *Establish a public relations and education program to increase community awareness for emergency preparedness, including “community emergency preparedness teams.” Involving residents and having voluntary programs to help people prepare is the key to an effective program. S-P-5 *Update subdivision and zoning ordinance review criteria to include seismic considerations. S-P-6 *Continue to inspect unoccupied existing unreinforced masonry structures and “critical facilities” constructed prior to 1948 and develop condemnation procedures to be included in a dangerous building ordinance. S-P-7 *Consult with a qualified engineering geologist to periodically review the Safety Element. 8.2 FLOOD HAZARDS Visalia is subject to flood hazards, but not inundation hazards related to dam failure. Since the climate is relatively arid and development continues to increase the amount of impervious surfaces, surface run-off and storm drainage must be managed. The average annual precipitation in the Visalia area is approximately 11 inches. However, portions of the Kaweah watershed which contributes to flooding in Visalia have a mean annual precipitation of 40 inches. Eighty–five percent of the annual precipitation occurs between November and April. In the Planning Area, waterways and surface runoff generally flow from east to west, terminating in the Tulare Lake Basin. Channels include the St. John’s River, Modoc Ditch, Mill Creek Ditch, Mill Creek, Tulare Irrigation District (TID) Canal, Packwood Creek, Cameron Creek, Deep Creek, Evans Creek, Persian Ditch (See Figure 8-2). Most watercourses are intermittent drainages that receive a significant portion of flow from storm water runoff during the rainy season. This intermittent flow is typically supplemented from water released from Terminus Dam on the Kaweah River. DRAFT ELEMENTS For General Plan Update Review Committee AUGUST 2012 8-5
