Ready, City Manager Initiated by: Public Works and Engineering Department SUMMARY Scientific studies are underway to determine the existence and location of an unmapped earthquake fault line near Garnet Hill. It is necessary for the City to review the geologic fault hazard report to be submitted, however, the City does not retain a qualified geologist on staff. Riverside County offers to provide a state registered geologist to review the geologic fault hazard report on behalf of the City, pursuant to the terms of their agreement. RECOMMENDATION: 1) Approve Agreement No. with Riverside County to provide review of site- specific geologic reports prepared and submitted to the City pursuant to the Alquist-Priolo Earthquake Fault Zoning Act; and 2) Authorize the City Manager to execute all necessary documents. STAFF ANALYSIS.- Element 6 — the Safety Element, of the City's recently updated and adopted General Plan, discusses seismic safety considerations for areas of Palm Springs. Please refer to Attachment 1 for a copy of the related section from the General Plan. Specifically, an earthquake fault identified as the Garnet Hill Fault extends from the area of Interstate 10 and Highway 62 to near the intersection of Interstate 10 and Gene Autry Trail. However, this fault is not yet mapped pursuant to the Alquist Priolo Earthquake Fault Zoning Act. The Alquist-Priolo Earthquake Fault ,Zoning Act was passed in 1972 to mitigate the hazard of surface faulting to structures for human occupancy. This state law was a Item 2 . 13 . City Council Staff Report November 14, 2007 - Page 2 Garnet Hill Fault Study direct result of the 1971 San Fernando Earthquake, which was associated with extensive surface fault ruptures that damaged numerous homes, commercial buildings, and other structures. Surface rupture is the most easily avoided seismic hazard. The Alquist-Priolo Earthquake Fault Zoning Act's main purpose is to prevent the construction of buildings used for human occupancy on the surface trace of active faults. The Act only addresses the hazard of surface fault rupture and is not directed toward other earthquake hazards. The Seismic Hazards Mapping Act, passed in 1990, addresses non-surface fault rupture earthquake hazards, including liquefaction and seismically induced landslides. The law requires the State Geologist to establish regulatory zones (known as Earthquake Fault Zones) around the surface traces of active faults and to issue appropriate maps. ["Earthquake Fault Zones" were called "Special Studies Zones" prior to January 1, 1994.] The maps are distributed to all affected cities, counties, and state agencies for their use in planning and controlling new or renewed construction. Local agencies must regulate most development projects within the zones. Projects include all land divisions and most structures for human occupancy. Single family wood-frame and steel-frame dwellings up to two stories not part of a development of four units or more are exempt. However, local agencies can be more restrictive than state law requires. Before a project can be permitted, cities and counties must require a geologic investigation to demonstrate that proposed buildings will not be constructed across active faults. An evaluation and written report of a specific site must be prepared by a licensed geologist. If an active fault is found, a structure for human occupancy cannot be placed over the trace of the fault and must be set back from the fault (generally 50 feet). Earthquake Fault Zones are regulatory zones around active faults. The zones are defined by turning points connected by straight lines. Most of the turning points are identified by roads, drainages, and other features on the ground. Earthquake Fault Zones are plotted on topographic maps at a scale of 1 inch equals 2,000 feet. The zones vary in width, but average about one-quarter mile wide. A fault is a fracture in the crust of the earth along which rocks on one side have moved relative to those on the other side. Most faults are the result of repeated displacements over a long period of time. A fault trace is the line on the earth's surface defining the fault. For the purposes of the Act, an active fault is one that has ruptured in the last 11,000 years. Surface rupture occurs when movement on a fault deep within the earth breaks through to the surface. Surface ruptures associated with the 1992 Landers Earthquake, in San Bernardino County, extended for 50 miles with displacements of an inch to 20 feet. Not all earthquakes result in surface rupture. The Loma Prieta Earthquake of 1989 caused 2 City Council Staff Report November 14, 2007- Page 3 Garnet Hill Fault Study major damage in the San Francisco Bay Area but the movement deep in the earth did not break through to the surface. Fault rupture almost always follows preexisting faults, which are zones of weakness. Rupture may occur suddenly during an earthquake or slowly in the form of fault creep. Sudden displacements are more damaging to structures because they are accompanied by shaking. Fault creep is the slow rupture of the earth's crust. Examples of creep are well known along the Hayward Fault where it crosses highly developed areas in Contra Costa and Alameda Counties. Although the Hayward Fault ruptured suddenly in the 1868 earthquake, it also exhibits slow surface creep which offsets and deforms curbs, streets, buildings, and other structures that lie on top of the fault. Because the Garnet Hill Fault is not yet mapped pursuant to the Alquist-Priolo Earthquake Fault Zoning Act, prior to any new development occurring in that area it will be necessary for a geologic fault study to be performed that specifically identifies the location of the slip fault and the resulting building setback offset limits. Currently, the property owner of land located east of Garnet Hill is working with a soil geologist to map the Garnet Hill Fault. In order to accurately review and assess the findings of the geologic fault study, it is recommended that the City refer the study to the Riverside County Chief Engineering Geologist to ensure the study meets the requirements of the Alquist-Priolo Earthquake Fault Zoning Act, and that the fault is accurately mapped. Staff recommends that the City use the County's standard form agreement for the purpose of providing peer review of the geologic fault study to be submitted to the City for approval. The alternative would require the City to obtain professional services from a competing professional soil and geology firm, and given the legal importance of the geologic fault study, staff recommends that the peer review be performed by a governmental agency rather than another private firm. FISCAL IMPACT: None, any fees to be paid to Riverside County associated with the agreement will be paid by the property owner or his agent submitting the geologic fault study to the City for review and approval. 3 City Council Staff Report November 14, 2007 - page 4 Garnet Hill Fault Study SUBMITTED: Da--yid, Barakian ?homasJV+bsonDirector of Public Works/City Engineer istant Ci{y on David H. Ready, City er ATTACHMENTS: 1. Palm Springs General Plan excerpt 2. Agreement 4 CITY OF PALM SPRINGS GENERAL PLAN GOALS, POLICIES AND ACTIONS This section contains an overview and policy direction related to safety Provisions within the City.The safety items addressed in this clement should be given careful consideration when new development, roads,parks, critical emergency facilities, infrastructure, or ocher projects are designed. S)EISNIC SAFETY CONSIDERATIONS The City of Palm Springs is located in an area subject to substantial seismic hazards such as earthquakes, liquefaction and earthquake-induced slope failure and landslides These seismic hazards can affect the structural integrity of buildings and utilities, and,in turn, cause property damage and potential loss of life. Although it is not possible to prevent earthquakes, their descruc- cive effects can be minimized through comprehensive hazard-mitigation programs and efforts. Earthquakes and Fault Zones The City of Palm Springs is located in an area where numerous active faults arc present. At least two active faults, the Banning and Garncr Hill faults, depicted in Figure 6-1,Seeinnic Iirazardi,extend through portions of the City. Both fault zones are capable of causing damage to the City. Other faults in Seismic Shaking: Lateral the region, such as the San Andreas, San Gorgonio Pass, and San Jacinto movement,or acceleration,e. the faults, also have the potential to produce strong reismic shaking m Palm ground during an earthquake.

Active faults are present along typically results in a small the northernmost reaches of the City,where dhe traces of the Garnec Hill and percentage of the total damage in Banning faults have been mapped.These faults have the potential to generate an earthquake,being too close to a surjieca rn/gtaare or ground deformation in the City of Palm Springs.As shown rupturing fault can cause severe in Figure 6-1,an Alquist-Ptiolo Earthquake Faulr Zone has been assigned ro damage to structures. the portion of the Banning fault chat extends rhrough Palm Springs, and co Surface Trace: Commonly the San Gorgonio Pass fault located immediately north of the City's referred o as a"fault lint,"it is the intersection of a fault plane with norchwest corner.Under the Alquisr-Priolo Farchquakc Fault Zoning Act,the the surface of the earth. location of structures for human occupancy across the surface trace of an active fault is restricted.A Riverside County Fault Management Hazard Zone has been assigned ro the portion of the Garnet Hill fault than extends through the City. Although the Garner IIill fault is nor designated as an Alquist- Priolo fault zone, Riverside County has established Fault Management Hazard Zones in order to require subsurface investigations of the Garnec Hill fault to determine, over time, if the traces of the fault are active. This Page 6.2 Palm Springs 2007 General Plan 6 SAFETY ELEMENT designation for the Garner Hill fault allows the City of Palm Springs to regulate future development across the trace of the fault. Consideration should also be given to known faults iliac, though not active, are[napped in the Palm Springs area, including but nor limited to the South Pass fault, the Palm Canyon fault, and the Deep Canyon fault(see Figure 6-1). Laws to Mitigate Ealrthgixalce Hazards The State of California regulates development in potentially seismically active areas through a variety of cools chat reduce or mitigate potential hazards from earthquakes or other geological hazards. The Gcelifornia 13uildhi Q Coyle(CBC)contains provisions to safeguard against major structural failures or loss of life caused by carthquakcs or other geologic hazards, and identifies zones of seismic activity subject to varying degrees of Potential impact and frequency of large earthquakes. The City of Palm Springs lies entirely within Seismic Zone 4 and is potentially subject to the highest acceleration, or changes in speed or velocity, due to seismic shaking. Enacted in 1986, the Univiuforcecl Alcasomy Lam requires all cities and counties within Seismic Zone 4 to identify potentially hazardous unreinforced masonry (URM) buildings in their jurisdictions, establish a URM loss- reduction program, and notify the owners of such buildings of the potential earthquake hazard their buildings pose The primary purpose of the Aleluiss-Priolo t;urthyncake Fault Zoning Act is to prohibit the location of structures for human occupancy across active surface traces of fault lines until gcotechnical investigations determine that a potential building site is safe for habitation. The Act also requires cities to disclosc co the general public,through the use of maps and other appropriate materials, areas that are subject to seismic hazards. The Seismic R azurds Majj)ing Act (SHMA) of 1990 addresses nonsurface fault rupture earthquake hazards, including strong ground shaking, lique- faction,and seismically induced landslides.The California Geological Survey (CGS)has nor yet mapped the Palm Springs area under Elie SHMA.Ilowcver, performing geological studies in chose areas identified as having a liquefaction or slope-instability hazard would reduce the potential for damage from these hazards. Palm Springs 2007 General Plan Page 6.3 7 CITY OF PALM SPRINGS GENERAL PLAN Liquefaction Liquefaction occurs when loose,soft, unconsolidated, or sandy soils iliac are saturated with water arc subjected to ground vibrations during a seismic even[. Significant ground shaking causes sod to lose strength and "liquefy" triggering scruccural distress or failure due to the settling of the ground or a loss of strength in the soils underneath structures. The northern and eastern areas of the City have a low possibility of being affected by liquefaction(see Figure 6-1).This hazard is considered low in the Palm Springs area because the approximate depth to groundwater is greater than 50 feet. Research and historical data indicate chat loose, granular materials saturated with groundwater and located at depths of less than 50 feet with silt and clay contents of less than 30 percent arc most susceptible to liquefaction.Shallow groundwater chat can concribure to the occurrence of liquefaction is known to occur locally in the downtown area, immediately surrounding the Agua Calienre Springs- A strong earthquake could cause liquefaction in this area, most likely expressed as "sand volcanoes" rmme- diacely surrounding the spring. Seasonal fluctuations in groundwater levels and the introduction of residential irrigation increase liquefaction risk. Earthqualce-Induced Slope Failures and Landslides Strong ground motions can worsen existing unstable slope conditions, particularly if coupled with sacrated ground conditions.Earthquake-induced slope failures generally include rock falls,landslides,and debris flows chat can overrun structures,people,or property,sever ucilicy lines,or block roads,which can hinder rescue operations after an earthquake.After the 1986 North Palm Springs earthquake,numerous landslides consisting primarily of debris slides and rockfalls were reported over an area of 600 square kilometers. The southern parts of Palm Springs arc most vulnerable to seismically induced slope failure, due to the steep terrain. Those areas of the City at the foot of the San Jacinto Mountains or below hills covered with large boulders are most susceptible to rockfall. In areas where there is development at the base of steep slopes, dislodged boulders can roll down onto roadways, with the potential to impact passing motorists.
