Both the type and level of investigation are described below. Type of Investigation EG: En2ineerinu, Geolot;:ic Investigation -An investigation that would evaluate the geologic conditions and engineering characteristics of the site as it pr.;rtains to the planned development and long-term maintenance of the site. These engineering geologic conditions include items such as the characteristics of the gcolr.1gic units, geologic struL:turc, and ground water conditions.. SF, Soll and Foundqtion lnvestl2alloo -This type of investigation should focus on the engineering characteristics of onsite soils on which o1aructurcs will he founded and analysis and recommendations of foundation systems. Items of thi!; type of investigation would include the cvalualion of snil engineering characteristics (such as expansion, consolidation, grnin size, chemical composition, etc.), (.,"Valuation and mitigation or adverse gcotechnical L:onditiuns (~uch as sc1tlcment, expunsive soils. etc.) and gcotechnical design recommendations. for foundation systems. SL: Slope Stubility lnvestigadon -An evaluation of natural and proposi;--:d manufactured slopes for gross and surficial stahility_ The investigation might entail a subsurface investigaticm and literature review Ln determine the geology of l.he slopes, determination of soil strengths <1nd other engineering charact.cristic.'i, stahility calculations to dctcrn1inc ,'.-lope factorwof-safctics., design of slope buttress or other stuhilization methods and rccornmendtHions concerning slope construction and mainlenance.

Level of Investigation Uvel 1: Koutlne -Basic or standard study evaluating the nc1rmal hazards associated with the Hazard Category in relation to the type of investigation (e.g., geologic reconnaissance or limit'.!d subsurface investigation). '-"••I _2: U~talled · C-.omprchensive study evaluating all possible hazards associated with the Hazard Category in relation to the type of mvcsugauon (e.g., detailed subsurface investigation and analysis). General Notes I) This table is intended for general land-use planning only. The type and level of the investigations should be based upon site-specific L:undiLions, planned use, and building C:o(!C requirements . 2) Gcotcchnical lnvestigatiDns can range from very preliminary, feasibility-type stuJics utilizing available research data (at the planning sta~e..<:. of a pmj~cl) to in-depth in:cstigation requiring extensive field exploration and enginccring/ge<1logic/seismic analysis (at the des1gn/construct1on ~tagc). Depending upon the complexity of the geotechniL:al conditions in relationship to the proposed development, the (icotechnical investigation may either be routine or detailed. While cacli type of investigation deals with a specific gcotcchnical cond1lon(s), the d1flcrcn1 investigations typkally am incorporated into one gc:otcchnical report. 1) Some aspects of the investigations listed above may be beyond the purview of the gcotcchnical ccnsultant and should he performed by other qualllkd consultants (i.e., civil engineer, coa~tal engineer, structural engineer, etc.). 4) Refer to special State regulations regarding investigation standards and construction codes for schools and hospitals; alS<l Federal regulation:s for nuclear facilities. 5) LanJ uses such as disposal sites or mineral resource development and other appropriate studies may require a geologic investigation to evaluate impact as regards to slope stability <1nd subsidence effects. 1., Environmental Impact Reports (EIR) may be required to meet State as well as Federal guidelines, depending upon jurisdiction.

Site-specific studies are required to adequately characterize the seismic parameters used in the design of a structure. The numbers presented on the maps indicate relative seismic lntensilles that can occur to a particular urea during a major earthquake on the Rose Canyon Fault Zone. Major earthquakes on other regionally active faults may occur hut analysis indicated a major earthquake on the Rose Canyon Fault Zone would produce the greatest ground accelerations and highest seismic intensities. For this discussion, a major earthquake is considered to he an earthquake with a magnitude of approximately 7.0 or greater. The numberS or seismic ground shaking lutenslty values pruented on the maps range from 5.5 to 8.5 with the differences relating to a degree on the distance from the fault but more importantly due tn the differences between the types of bedrock und surficiul soils prtsent within the City, The Intensity values presented on the maps correspond to a level of ground shnking that have only • 10 percent chance of being exceeded In 50 yen.-s (which corresponds to a ground motloo that would be exceeded on the avera1-:e once every 47S years). This is the same way the values presented in the Uniform Building Code (UBC) are determined. The Seismic Ground Shaking Intensity Scale presents a description of the Intensity Values, listing occurrence• and/or damage that may oc<11r in each of the intensity ranges. Half-unit values (such as 6.5) on the maps represent the upper end of the Intensity values presented in the table to the right. 8ackgnmnd Several faults within southern California have the potential of generating earthquakes that will cause strong ground motions. Each of these potential earthquakes will affect the City differently depending upon the distance the earthquake is away from the City, sire and rupture mechanisms uf the earthquake and local geologic conditions. Some faults are alrn more likely to cause an earthquake than others. The faults that have been mapped within the City are all considered inactive (i.e. a fault that has not mnved within the last 11,000 years ~ the Holocene). Regionally active faults in southern California are shown on the l1gurc lO the left. Based on the proximity of a fault to the City and the known geologic/seismic conditions a number of faults (including the Rose Canyon, Coronado Banks. Elsinore, San Jacinto, and San Andreas Faults) were evaluated during the seismic ground shaking intensity analyses. A maximum probable earthquake is the largest earthquake a fault is predicted capable of generating within a specified time period of concern. such as 30, 50 or 100 years. A maximum credible earthquake is lhc largest earthquake a fault is believed capahk of generating regardless of the time span. The maximum credible earthquake on the Rose Canyon Fault Zone for this study was considered to be a 6.9 magnitude earthquake. For the Seismically Induced Ground Shaking Analysis Maps of Cerlsbad (presented on Pages 51 through 73), the seismic intensities were based on a level of ground motion that had only a 10 percent chance of being exceeded in 50 year;'\ (defined as the "effective pt"ak ground accdcratiun"). This value corrl'.spom1:s: to a ground motion that would be exceeded, on the average, only oni.:c in 475 years. "Effcclivc peak ground accelerations" were utilized for this study because they arc the same parnmctcrs ttrnt arc ~1tili1.<.xl in determining the seismic ground motions presented in the Uniform Building Cude (IBCO, 1991 ). It should be noted that maximum credible earthquakes are considered in the design of critical facilities such as dams, emergency operations centers, and hospitals. Ar;. a result, the values presented on the ground shaking intensity maps should not he utili1,ed for the planning of critical facilities. Earthquakes are normally c!BMified as to seserity according to their magnitude (usually using the Richter scale) or their seismic intensity. The destructiveness of an earthquake at a particular location is commonly reported using a seismic intensity scale. Seismic intensities arc subjective clas ... 'iifications based on observations of damage caused hy pa.iiit earthquakl':s. These are several seismic intensity scales hut the one used the most often is the Modified Mcrcalli Scale presented to the right. This scale has 12 levels of damage, the higher the number the greater Lhi.~ damage. An earthquake ha.o; only one magnitude hut may have scvcnd se.-··nic intem;itic& that generally decrea.o;e ~Lh innctJ:;ing distance from the soun.:c. Ground motion caused by earthquakes is generally ch;:iractcrizcd using parame:ters of ground displacement, velocity. and acceleration. Fur most seismic studies (including this one), the measurement used is peak ground acceleration. Although computer models arc now U!-icd routinely to predict grountl motions expected at a given s_ite as a result of an earthquake, it is ~till difficult to anticipate the damage sustained hy different types of buildings. This is hccausc the rc~ronsc nf strutlurcs to µ;round motion depends upon many fflctors including the i!mplitude, [rcyucncy and duration or ground shaking. Seismic Ground Shaking Intensity Analysis The Seismically Induced Ground Shaking Maps for the City of Carlshad were generated based on the results of a prnhahili.,;-,tic ground mo1inn analysis. The City was digitized into a grid system with 1.4 km spacing. The prnhahilistic effective pe:=ik ground a1..-celcration values (whi~h assume a lO percent prohahility of bl'ing exceeding in 50 years) were obtained at each grid point using Joyner, and Boore's (1981) acceleration attenuation equation. The controlling event was fnund io he a maximum prohahle earthquake on the Ruse Canyon Fault Zone. The peak ground acceleration values al each grid point were translated into the Modified Mercalli intensity scales u-;ing a comhimition of Richter's ( l 95R) and Evcrn<lcn and Thompson's ( 1988) empirical rehHiunships for predicting inlcn:sity in terms of accelerati()n.~. Thi;.~ inl.1..:nsity Sl'.ak: vc.1l ucs at each grid point were assumed to represent sites that consistl'.<l ofsaturntcd alluvium. The inlt.~n.sit.y 1-n.tlc values were then corrected [or ll.C type o[ bedrock using Evernden and Thompson's (1988) reeonimendations of negative corrections for intensity scales with respe1:;t to saturnt.cd alluvium. For example, an area having u intensity scale value of RO for saturated alluvium would be corrected to a value of 5.1 if it consisted of granitic bedrock or 6.0 if tt consisted of sedimentary bedrock. Typically, ground shaking intensity values are nDt defined in half-units (i.e., 5.5 or 4.5)_ In this stu<i'i, however. since seismic intensities. were calculated hased on effective peak ground accelerations (which gi~c values to lhe nearest tenth versus whole numbers), the seismically indu1..:c<l _ground shaking maps show int~nsity values in half-units. The use of half-units in presenting intensity values is not meant a~ an nuempl to introduce a new concept, but ratht:r, as a mci.lns of presenting data obtained from mathematical models rather than from direct observation LHlGHIDN AND ASSOCIATBS INC. 3934 MURPHY CANYON ROAD.

Corbett Avenue Portland, Oregon 97201-4830 , . 2. 3. 4. 5. NOTES The Catastrophic Dam Failure Inundation Zones are based on engineering and hydrogeology studies performed (for the most partl in the early 1970's. Since that, existing conditions (such as topography) may have been modified, consequently, the inundation zones should be used for planning purpose only. If a more detail study is needed, the original study (listed in the Hydrogeology References n Page 84) should be obtained and utilized. Where significant changes in topography or other conditions have occured since the original studies were performed, the inundation zones were revised to reflect the changed conditions (which generally consisted of raised grades on the canyon or valley floor). Inundation zones that have been changed include; 1) the Stanley Mehr Reservior inundation zone in the vicinity of Stage Coach Park and the area northeast of Rancho Santa Fa and Olivenhein Roads; and 2) the Lake San Marcos Inundation Zone on the north side of the zone in the vicinity of Corte de Vista (to the east of Batiquintos Lagoon where the canyon bottom widens outl. Both of these areas are located on the bottom of Page 82. The Catastrophic Dam Failure Inundation Zone for Calaveras Lake was based on data obtained through Carlsbad Municipal Water District (Inundation Map of Squires Darn and Reservoir, Carlsbad, California showing the Calaveras Dam Inundation Area plotted January 10, 1975). The Catastrophic Dem Failure Inundation Zone for Squires Dam and Reservoir was based on engineering analysis performed by Woodside/Kubota and Associates, Inc. for the Carlsbad Municipal Water District in the early 1970's. The Catastrophic Dam Failure Inundation Zone for the Stanley Mahr Reservoir was based on analysis performed by Camp Dresser and Mckee, Inc. for the Vallecitos Weter District in July 1992. 6. The Catastrophic Dam Failure Inundation Zone for San Marcos Dam No. 848 (Lake San Marcos Dam) was based on engineering analysis performed by CM Engineering Associates for the Citizens Development Corp. dated November 26, 1973. The Tsunami and Seiche Hazard Zone was based on a number of published reports dealing with Tsunami Hazards along the southern California coastline (Garcia and Houston 1974; Iida 1969; Joy 1968; and Whalen 1970). Tsunamjs sea waves can be generated by a submarine earthquake, landslide or volcanic activity which displaces a relatively large volume of water in a very short Pacific Ocean period of time. Seiches are periodic oscillations in a body of water (such as a lagoon or lake) and can be caused by tsunamis, earthquakes, submarine landslides, storm winds or surge and barometric disturbances (Joy 1968). During the past 1 70 years, numerous tsunamis have occurred (including six great tsun8misl with the P8Cific Ocean Basin C8using wave heights no gr88ter than normal tides along the San Diego Coastline. Interestingly, the six great tsunamis represent an event from each of the major generating zones within the Pacific Ocean Basin (Joy 1968). Based on the historical events and the generally accepted and favorable geologic end seismic conditions along the San Diego County Coastline, the potential for damage caused by tsunamis or seiches can be considered very low. However, minor problems such as flooding and material damage to some low-lying waterfront structures might occur within the tsunami and seiche hazard zone indicated on the map. @) 1181 aTY OF CUI re& LEGEND Cateetrophic Dam Failure Inundation Zonas 1 b\,._~ C.aleveras Lake Inundation Zone 2 V✓.::::1 Squires Dem lnundl:.t:ion Zone~ [I]] Stanley M•hr/Lo Coste Dom lnund•tion Zone • □ Lake San Marcos Dam lnundatio11 Zone ft Tsunami and Seiche Hazard Zone CJ Coastal and low-lying inland areas subject to tsunami or sciche ha7.ards 9 Footnotes 1 through 6 aro deocribed In the notes on paga 79.
