Belanger, City Manager RE: Response to Questions Raised by Morning Sun Homeowners Pertaining to Landslide Located at Shepard Hill and Morning Sun, Within the Westerly Portion of Diamond Bar DATE: October 17, 1995 Is the landslide still moving? The Walnut Valley Unified School District's civil engineering and geotechnical consultants have been monitoring fixed reference points since the landslide fully manifested itself. It is reported that the area around the escarpment is moving at the rate of approximately three inches per week. 2. When will information related to geotechnical studies be made available? Sasak Development Company has submitted geotechnical information related to landslide remediation. This information has been transmitted to Leighton & Associates, the City's geotechnical consultant, for review and comment. WVUSD has been requested to provide geotechnical information and remediation plans related to the landslide area and a permanent solution related to the uncompacted surplusage stored along the sides of the canyon located easterly of the landslide area. To date, the requested remediation plans from WVUSD has not been received, although the District engineer has been requested to prepare such remediation plan. However, an eight page, preliminary geologic report, which was sent to State OES has been received. 3. What are the plans for repair of the hillside? The area involved in the landslide needs to be remediated. The property owners have been requested to provide remediation plans to the City for review, comment and approval. Sasak has submitted such plans. WV`USD has not submitted such plans. 4 When can homeowners expect compensation for their losses? Based upon the known facts and circumstances related to the landslide, issues related to liability should raised with property owners who own the property involved in the landslide. 5. Have erosion control plans been submitted and approved related to the landslide area and the uncompacted fill site? Erosion control plans have been submitted to the City, by WVUSD, for Sasak and District properties. Los Angeles County Public works have reviewed and approved the plans as they pertain to County property and structures. The City Engineer has reviewed and approved the erosion control plans. 6. Are 50% of the flood control devices inoperative? This question will be answered within the next week. Questions regarding rainfall run-off quantities related to flood control structure capacity will also be answered. 7. When will repairs be made to water lines and fire hydrant? Walnut Valley Water District has indicated that permanent repairs will be made after the landslide area has been remediated. As regards fire protection, the Los Angeles County Fire Department is aware of the hydrant status in the Morning Sun/Shepard Hill area. LACoFD pre -planning includes a feeder hose drop at the Shepard Hill hydrant for fire suppression requirements on Morning Sun north of Shepard Hill. Has the Sasak tentative tract map been approved? The Sasak tentative tract map approval has conditions precedent which must be satisfied before the resolution approving the tract map can be signed by the Mayor. Sasak must provide a remediation plan for its property and provide a faithful performance bond to cover the cost of such landslide remediation. To date, the conditions precedent have not been satisfied. WOodwan:1-Clyde mr Engineering d sciences at7phao to the earth & rtS environment July 25, 1995 Project No. 954E140 Mr. Eric Koch WL\ Governor's Office of Emergency Services 74 North Pasadena Avenue - ✓ West Annex, 3rd Floor Pasadena, California 91003-3678 SUBJECT: PRELIMINARY GEOTECHNICAUGEOLOGIC REPORT MORNING SUN LANDSLIDE DIAMOND BAR, CALIFORNIA Dear Mr. Koch: This letter is written on behalf of the Walnut Valley Unified School District (WVUSD) and provides Woodward -Clyde Consultant's (Woodward -Clyde's) preliminary report regarding observations of the Morning Sun Avenue landslide which occurred in Diamond Bar, California on May 19, 1995. In addition, this letter also provides our assessment of the current conditions of the landslide and temporary fill areas, as well as possible methods for long-term stabilization of these areas. BACKGROUND The location of this landslide is shown on Figure 1. Based on our data review and observations, the site of the landslide has remained largely undeveloped.' None of the geologic reports reviewed indicated the presence of a pre-existing ancient landslide, although out -of -slope dipping beds had been mapped in the area. In about 1967, the housing tract located immediately west of the Morning Sun landslide was graded. The construction included: filling a canyon west of the landslide, preparation of a small stabilization fill at the base of the slope adjacent to the 1700 Block of Morning Sun Avenue, and grading an approximately 400 -foot -long section of the natural slopes along the 1600 Block of Morning Sun Avenue to an inclination of about 3:1 (horizontal to vertical). Surface drainage consisting of concrete "vee" -ditches was placed along the perimeter of these graded slopes. During the late -winter and early -spring of 1995, evidence of surface distress was reported by residents of the 1600 Block of Morning Sun Avenue. The reported distress included water I Available sources of data and information included personal communications, geologic reports, consultants geotechnical reports and maps, and aerial photographs covering the period from 1928 to the present.

On March 12, 1995 the Walnut Valley Water District repaired a broken water pipe in the same area along the east side of Morning Sun Avenue. During the first week of April, 1995, additional cracking of the curb and further buckling of the pavement adjacent to 1635 Morning Sun Avenue was noted by the residents. In mid-April, 1995, residents in the area reported observing cracks in the "vee - ditches" on the natural slope east of Morning Sun Avenue. At least three additional water line breaks in April and early May, 1995 caused the Walnut Valley Water District to move the pipe above ground on May 15, 1995. During the week of May 15, 1995 movement of the incipient slide, as observed by others, apparently was gradually increasing based on deformation of the curb and street. Movements accelerated to about 7 to 10 feet per day and the full extent of -the Morning Sun landslide occurred on May 19, 1995. This failure was in the form of approximately 5.5 acres moving down slope toward the northwest. The configuration of the Morning- Sun Landslide is shown on Figure 2. On the afternoon of May 19, 1995, Woodward -Clyde Consultants (Woodward -Clyde) was requested by the WVUSD, through NBS/Lowry, to provide geological/geotechnical engineering services assisting in emergency efforts to mitigate a landslide that was threatening four residences. These four residences are located on the east side of the 1700 Block of Morning Sun Avenue, south of its intersection with Shepherd Hill Road. The landslide was also overrunning the 1600 Block of Morning Sun Avenue, north of Shepherd Hill Road, threatening to block access to the homes located on the west side of the road and in a cul-de- sac at the north end of the road. The head scarp and upper portions of the slide are part of WVUSD's property located on the west side of Lot 49, Tract 32576. The northern portion of the slide is on private property owned by Sasak Development Company. The homes along Morning Sun Avenue are under the county's jurisdiction, who is also responsible for maintaining the roads and public safety for the residences. The landslide occurred in the closing months of the 1994-95 rainy season, which produced about 28 inches of rain, as measured by the National Oceanic and Atmospheric Administration at a weather station located at Los Angeles County's Fire Station 102C in the City of Walnut. Of this total, about 22.5 inches fell in the period from January 1 to March 12, 1995, immediately prior to the onset of observed distress. This rainfall amount for January through s.\Exs`OEs2.RYr 7/25/95 Woodward -Clyde Conaw"ants V*xx WAId-C1yde Mr. Eric Koch Governor's Office of Emergency Services July 25, 1995 Page 3 March approximately doubled the average rainfall over the last 30 years for the same three- month period. It is not uncommon for landslides in southern California to occur in a period of several months following heavy, sustained rainfall. This is because it may take some time for the water to percolate down to and soften the critical slide plane. DESCRIPTION OF LANDSLIDE The landslide occurred on a north trending ridge of the Puente Hills, which is underlain by interbedded sandstone and siltstone of the Puente Formation. The landslide is approximately 1,000 feet long along the west side (the toe of the slide) and about 450 feet wide along its prominent 25- to 30 -foot -high, east -west trending back scarp that cut through the ridge at about elevation 830 feet. The landslide is interpreted to be a block slide along an out -of -slope - dipping clay seam based on our observations of the shape of the slide, exposures of the slide plane along its east margin, and geologic data regarding the bedding orientations in and surrounding the slide. The mechanisms of the slope failure is most likely related to migration of water within the slide mass which weakened and softened the clay seam, leading to the slide movement. - In order to better understand the mechanism and extent of the landslide to facilitate emergency measures to stop the slide, the WVUSD authorized Woodward -Clyde to initiate a field investigation on May 21, 1995. The subsurface exploration was carried out simultaneously with the emergency grading operations. The locations of the field exploration are shown on Figure 2. Geologic mapping of surface exposures was performed in the areas of the slide, the ridge above the slide and the area of the disposal fill aided by fifteen backhoe test pits (TP -1 through TP -15). Five auger borings (B-1 through B-5) were drilled through the slide mass in order to collect nearly continuous core sample. These borings were completed with pvc standpipe peizometers, which were monitored to obtain subsurface information until the pipes were sheared off by the sliding mass. Two auger borings, BA -6 and BA -7, were completed near the southwestern edge of the landslide. These borings were completed with combined inclinometer and peizometers. In addition, auger borings, BA -8 and BA -9, were completed near the northern limit of the temporary fill area. Twelve bucket auger borings (BA -1 through BA -12) have been drilled and downhole -logged to evaluate the geologic conditions in the area above the head scarp, north of the toe of the landslide east of the 1700 Block of Morning Sun Avenue, and in the potential disposal fill areas. Six rotary wash borings (RW -1 through RW- S:THS\OES2.RPT 7,13/93 Woodward-CfVde eew•vn.Ms Woodward -Clyde Mr. Eric Koch Governor's Office of Emergency Services July 25, 1995 Page 4 6) were drilled to collect continuous core or undisturbed pitcher samples in the bedrock below the slide for laboratory testing. Inclinometers and piezometers were installed in RW -1 and RW -2. Piezometers were installed in RW -5 and RW -6 to monitor fluctuations in groundwater levels. Samples collected during the field exploration are being tested in Woodward -Clyde's soils laboratory to developed data regarding the materials within and beneath the landslide mass SHORT-TERM GRADING OPERATIONS On Friday, May 19, 1995, the WVUSD realized that immediate action was necessary to stop the landslide from impacting the four homes. Emergency grading operations began on May 20, 1995 with bulldozers brushing the landslide area, followed by lowering the grade of the head of the landslide below the level of the backscarp graben. An area to the east of the landslide was identified as a temporary disposal fill area for the materials removed from the landslide, as shown on Figure 2. Bulldozers continued to move soil from the top of the landslide on May 21, 1995, and started brushing the proposed fill area. The urgent nature of the situation required immediate response to stop the slide from damaging or destroying adjacent property. Because of this, there was no time to prepare grading plans for the temporary stabilization work. As such, ` the emergency grading operations required constant monitoring and input from the geologists and engineers to the grading contractor to keep the work progressing and to modify the work as necessary (usually several times per shift). In addition, the slide mass was very dynamic, and the rate of movement and direction changed rapidly in response to the grading efforts, as discussed below, which also necessitated constant observation and quick field modifications to the procedures being implemented. The grading activity intensified on May 22, 1995, as additional equipment was mobilized to the site. The grading operation concentrated on cutting of a slot to the east of houses on the 1700 Block of Morning Sun Avenue to decouple the landslide from its toe, thus gaining control of the movement into the homes. In addition, grading was done to prepare the temporary fill area to receive fill. Grading was also done to prepare pads for exploration drilling. This included the use of scrapers to move top soils to a stock pile in the east canyon area. The grading activities were conducted in two, 12 -hour shifts. As the slot behind the four houses was excavated, the slide moved into the slot cut and had to be removed to S:1EHS\OES2.Rrr 7/25/95 w.wwsrd•clyde canaWbwts OOdWBrdIyd@ Mr Eric Koch Governor's Office of Emergency Services July 25, 1995 Page 5 prevent the slide from recoupling with its toe. The grading operation during this stage also included using a long reach excavator and bulldozers to remove soil from behind houses on the 1700 Block of Morning Sun Avenue and push it into the slot cut area where the scrapers could pick it up and haul it to the temporary fill area. The slot cut behind the four houses on the 1700 Block of Morning Sun Avenue was excavated through about 70 percent of the bottom slide surface by Saturday, May 27, 1995; and the mass between the slot cut and the houses at that time reached temporary equilibrium. The grading operations then shifted their focus on the northern portion of the slide to stop movement along the east side of the 1600 Block of Morning Sun Avenue. Two large excavators were used to remove the toe of the landslide from Morning Sun Avenue. The excavators collected the soil and placed it where bulldozers could move it into an area where the scrapers could pick it up and haul it to the temporary fill area. The emergency grading operation continued in the northern portion of the slide until Tuesday, May 31, 1995. During the period when grading was focusing on the northern portion of the slide, the slide had moved into the slot cut behind the four houses on the 1700 block of Morning Sun Avenue, and. grading operations had to return to this area to maintain an open slot and a decoupled toe. The landslide in this area continued to move slowly into slot. Twenty-four hour operations concluded with the night shift on May 30, 1995. Enough of the landslide had been removed to slow the rate of movement such that the encroachment onto the four homes or on the southern portion of Morning Sun Avenue could be controlled with only daylight operations. Emergency grading operations continued to remove the landslide mass to the east of the four houses on the 1700 Block of Morning Sun Avenue until June 9, 1995. At this time a relatively small amount of the landslide is left above the four houses, and the slow movements that continue to occur would not impact the houses unless left unattended for an extended period of time. The temporary grading operations included wheel rolling of the exposed soil to reduce erosion, and also included placement of erosion control provisions for drainage control. Sandbags were placed along the east side of Morning Sun Avenue to protect the street and cul-de-sac in the event of rain. This proved effective during the rains that occurred on June 15 and 16, 1995. S•\EH&0ES2.Rrr 7123/93 Woe"erd.elria Consultants V*Odward-CIVde Mr. Eric Koch Governor's Office of Emergency Services July 25, 1995 Page 6 CURRENT CONDITIONS The short-term grading operations described in the previous section resulted in the following The slot cut behind the houses on the 1700 Block of Morning Sun Avenue provided the mechanism for decoupling the main landslide mass from the toe of the slide immediately behind the houses. The slot cut also allowed for the grading operations to continue removing the slide mass from behind the houses. The current toe of the landslide is located about 115 feet east of the property line of the four houses. The portion of the area below the slide plane has been graded to about 3: 1 to 4: 1, or approximately parallel with the underlying bedding angle. However, the remnant of the main landslide mass is still moving, but at a slower rate of 1/3 to 1/2 feet per day toward the four houses and Morning Sun Avenue (north of Shepard Hill Drive). 2. The headscarp was left largely intact with minor grading at the top and the bottom to break off the over std portions. Based on our field exploration program, the head scarp is .underlain by an ancient failure plane that may coincide with the failure plane that was observed underlying the main slide mass. This ancient failure plane is interpreted to extend another 320 feet uphill from the edge of the headscarp. Our preliminary slope stability analyses indicate that this section is marginally stable under current short-term conditions and would be unstable under long-term conditions. Our analysis also indicates that the head scarp may not be stable under adverse short-term conditions such as future heavy rains, an increase in hydrostatic pressures due to a rise in groundwater levels, or earthquake loading. Due to emergency nature of the situation, approximately 220,000 cubic yards of material removed from the landslide was placed in an uncontrolled fill (non - engineered) in the designated area within the canyons east of the slide, as shown in Figure 2. The fill material consists predominantly of silty sand soils. This fill is currently 50 feet high with side slopes ranging in inclination from about 1:1 to 1-1 /4 1 Preliminary geologic observations indicate a softened clay layer is present that could be the slip plane of a shallow landslide located near the proposed toe of this fill (northern section). SAEMOESIRPT 7/25/95 W"dwaN-Clyde Cewwltents C Mr. Eric Koch Governor's Office of Emergency Services July 25, 1995 Page 7 CONCLUSIONS In our judgment, the three main items discussed above are considered adverse geologic and geotechnical conditions and are considered likely to pose imminent danger for the following reasons: The remnant of the main landslide mass is still moving and needs to be entirely removed as planned. The potential of the head scarp moving on the identified ancient slide plane is considered to be high; especially under increased hydrostatic conditions or during seismic shaking. In addition, brush fires common to heavily vegetated slopes in southern California could also have an adverse effect on the upper ridge area. In the event the head scarp fails, the concerns are additional and accelerated mass movement towards the houses on the 1700 Block of Morning Sun Avenue and on the north portion of the road, and possible further threat up slope towards the adjacent property. • The stockpile material placed temporarily in the eastern canyon area is granular and loose. The likelihood of this material being washed downslope into the natural drainage during rain is considered very high. In addition to the major runoff that could potentially affect the immediate houses north of the fill, there is the concern that if this material plugs the only storm drain inlet, then flooding will occur as shown on Figure 2. This concern has also been expressed by the Los Angeles County Flood Control District. Because of the hazard posed by the remaining slide mass and the head scarp, Woodward - Clyde is monitoring the inclinometers and piezometers on a weekly basis. In addition, NBS/Lowry surveyors are checking 32 survey points located on and around the landslide on a weekly basis. LONG-TERM STABILIZATION Our plan for the long term stabilization is based on addressing the adverse conditions discussed previously under "Current Conditions" and are considered as a continuation of the initial grading operations. The inception and conceptual level plans for the long term S:\EHS\OES2.RPT 7M/95 Woodward -Clyde Consultants Woodward -Clyde Mr. Eric Koch Governor's Office of Emergency Services July 25, 1995 Page 8 stabilization started simultaneously with the grading operations. The main components of our long term stabilization plan include the following: I . Removal of the remainder of the landslide mass. 2. Developing a buttress fill to support the head scarp. Currently we are considering a buttress fill with a horizontal key width of about 200 feet. The height of the buttress will range from about 100 to 125 feet. 3. Providing positive surface and subsurface drainage for the buttress fill and other areas within the landslide mass that could be affected by future water. 4. Regrading and engineering of the fill placed in the stockpile area for long-term stabilization. Our plans include removal of existing loose soils, placement of additional new engineered fill to buttress the existing fill slope, and providing a positive drainage system. It should be noted that the slide removal area and temporary stockpile have currently reached temporary equilibrium in the short term due to the lack of heavy rain during the summer months. However, as stated above, in the event of heavy rainfall, we anticipate that these areas will experience instabilities with respect to slope stability and erosion. Therefore, the window of opportunity is limited to initiate and complete stabilization grading and develop a stable site before the next rainy season starting October 15, 1995 (as determined by the L.A. County grading code). GENERAL LEWrATIONS This letter report presents information regarding the subject landslide based on our observations, geologic mapping, field exploration, inclinometer readings, survey measurements, and limited laboratory testing. All of these activities are currently in progress in various degrees. Therefore, the possibility of diffi rust conditions than those described in this letter should not be discounted in the event new information is developed in the future. As discvssed in the main text of this letter, there are several geologic and geotechnical conditions that currently present hazards at the site. These conditions are being monitored and will remain as hazards until the long term stabilization measures are in place.

Acting City Engineer RE: Morning Sun Landslide Dear Mr Myers: This letter is in reply to your letter dated September 15, 1995, addressed to Dr. Ronald Hockwalt, the Superintendent of Walnut Valley Unified School District, regarding the Morning Sun landslide. No work has been done on the site of the landslide since June 9, 1995, except for the placing of sandbags, at the site on June 13, 1995, and adding approximately 2,000 sandbags on June 18, 1995. Attached hereto are maps showing the before and after condition of the land as affected by the grading. This is based on aerial surveys and show the grading as as -built. The grading that was accomplished from the commencement of the landslide through and including June 9, 1995, was in response to an emergency situation to protect the adjacent homes on Morning Sun and other adjacent properties. Also attached are erosion control plans that are being put in place to protect against erosion. Those erosion control measures will be in place by October 15, 1995. The Districes consultants are still preparing final grading plans. A substantial part of the properties are not the property of the District, as they are owned by Mr. Amrut Patel. The District suggests that the City look to Mr. Patel for necessary grading and erosion control on his properties. If you have any questions, we would be glad to assist you.
