COLLINS LAW FIRM The Aon Center 707 Wilshire Blvd., Suite 4880 Los Angeles, CA 90017 SUBJECT: NUISANCE ABATEMENT COSTS Dear Mr. Sheen and Mr. Collins: At the regular City Council meeting held on September 26, 2005, the City Council declared a public nuisance on the property at 1 Poppy Trail and required specific corrective actions to be completed by the property owner of 1 Poppy Trail. These actions are described in the attached correspondence. Required actions were not taken by the property owner, therefore, after appropriate notification to the property owner, and after issuance of an abatement warrant by the Superior Court, the City initiated and completed the nuisance abatement. Rolling Hills Municipal Code Section 8.24.060 requires the City to notify the property owner that this nuisance has been abated by the City and provide the cost of the abatement. The cost bill for abatement is attached. The enclosed cost bill will be presented to the City Council for approval at its regular meeting of Monday, April 10, 2006, at 7:30 p.m. in the Rolling Hills City Council Chambers, 2 Portuguese Bend Road. You are invited to attend this meeting and offer any comments or objections you may have to the bill. The Council may approve the enclosed cost bill, or make any modifications to it as may be appropriate. Pursuant to Rolling Hills Municipal Code Section 8.24.070, you are required to pay the cost bill approved by the Council, if any, in full within ten (10) days of Council approval.

THE CITY COUNCIL OF THE CITY OF ROLLING HILLS DOES HEREBY FIND DECLARE AND ORDER AS FOLLOWS: Section 1. Pursuant to Section S.2 .0.0 of the Rolling Manager notified Mr. Alan Sheen, owner of that certain real property�inn theici City ofCode,the RollCity ing Hills commonly known as 1 Poppy Trail (Lot 90-B-RH), to abate conditions on his property that would potentially aggravate and accelerate an existing sealing renewed tension cracks to prevent water infiltration, Idemolishing the guesthouseandslie. The measures laude and removing all debris from the site, flattening the headscarp to a 1:1 slope, covering the entire affected area with UV resistant plastic sheeting, and installing temporary drainage devices to divert stormwater from entering the landslide area from locations above the headscarp of the landslide.- The notice directed that the measures be taken within 15 days of the date of the notice, otherwise the City Council would hold a public hearing on September 26, 2005 in the City Council Chambers of City Hall to hear any protests the owner might have to the abatement of the nuisance. On September 2, 2005 the City posted a notice of substandard exist on the property. property at the site apprising the property owners of the unsafe and unsightly conditions that Section 2. No action to abate the nuisance has been taken by the property owner. Consequently, on September 26, 2005, the City Council held a public hearing to allow the City Manager, the property owner and any other interested regarding the condition of the property located at 1 Popp�ryTrail.The�fpropertyand �owner did t attend the public hearing. The property owner's attorney, Craig Collins was present and participated in the hearing. Section 3. Based upon staff reports, related documents and the evidence presented at the time of the hearing, the City Council makes the following findings of fact: a. The property located at 1 Poppy Trail is located in an active landslide in the City of Rolling Hills. The property is improved with a single family residence, swimming pool, water feature, stable, tennis court and illegal nonconforming guesthouse. Inspections of the property demonstrate that the single family residence and guesthouse are presently uninhabited. b. Following the activation of the landslide in early 2005, a geologist engaged by the City, with the property owner's permission, conducted borings and other tests on the property to better understand the structure of the landslide in order to enable all interested parties to evaluate their options. A copy of the geologist's report was provided to the owner of 1 Poppytrail. c. - Currently, the foundation of the guesthouse is exposed from below and rests at the top of the active landslide. The guesthouse's concrete foundation was damaged in the landslide, and it continues to suffer damage as the ground moves. The guesthouse was red -tagged as unsafe to occupy by the County of Los Angeles 2005 and in its current condition, it cannot he used; further it is unsightly and causeS visual i ual blight. Due to its location in a landslide, its condition will only worsen, and with additional rain will likely fall into the canyon. Hence, the guesthouse representsa danger to residents, adjoining properties, public utilities, roads and trails. d. The driveway on the property has major cracks and directly involved in the landslide. Irrigation and drainage I portions ared non-functional. The exposed drainage devices, exposed headscarp are ofnthe lan exposed de and unmodified headscarp will permit the intrusion of water into the landslide, that will continue to adversely impact the stability of 1 Poppytrail as well as that of surrounding properties, roads and trails. e. Allof the foregoing together or separately,. as further described in the attached correspondence (Exhibit A) represent a public nuisance and a threat to public safety. Section 5. On the basis of the foregoing, and of the evidence contained in the record," the City Council finds and determines that the landslide condition of the property at 1 Resolution No. 996 -1- • Poppytrail, the condition of the guesthouse, the bpen crevices and fissures, and the exposed irrigation and drainage pipes and facilities separately and collectively constitute a public nuisance within the meaning of Sections 8.24.010 and 8.28.010 of the Municipal Code, and constitute a condition that is injurious to the public health, safety and welfare. The.Cily Council further finds that by allowing the above described conditions to remain unabated through the 2005-2006 winter rainy season, stormwater will further infiltrate the landslide and will further destabilize the property and the guesthouse, creating a danger to persons and property in the area. . Section 6. In accordance with the foregoing, and.because it is the duty of property owners to maintain their properties free of nuisances, the City Council orders that the property owner prepare and submit• a written plan to the City within ten (10) days of the adoption of this Resolution providing for implementation of the corrective winterization measures described in Section 1 of this Resolution and further described in the attached correspondence (Exhibit A); further, that the property owner commence implementation of the plan and performance of the corrective measures on or before October 10, 2005; and, that the corrective measures he completed by the property owner on or before November 10, 2005. In the event . that the property owner fails to submit a plan and/or fails to commence performance of the corrective measures by the above -described deadlines, than the.City may, on or after October 26, 2005 perform the corrective measures at the property owner's expense as authorized in Section 8.24.060 of the Municipal Code. • Section 7. In the nuisance is not abated as specified herein, then the City Manager is directed to cause the nuisance to be abated by the City, and also is directed to notify the property owner in writing by certified mail and regular mail of the cost of removal of the nuisance and that payment in full for removal of the nuisance is due to the City within 10 days of the date of mailing of the notice. If the total cost of abating the nuisance is not paid to the City within 10 days after the date of the notice, the City Clerk shall record, in the Office of the County Recorder, a statement of the total balance due to the City, which shall constitute a lien upon the property. Section 8. The City Clerk is hereby directed to send a copy of this resolution by certified and regular mail to the owner of the property located at 1 Poppy Trail. Section 9. This resolution shall take effect immediately on September 26, 2005. PASSED, APPROVED AND ADOPTED THIS 26'" DAY OF SEPTFF ER, 2005 ATTEST: Cradi R.

As part of the pre -construction phase of this grading, GDC is installing 3 inclinometers to monitor landslide movement during grading. This data will help determine the stability of the landslide. Closure This letter summarizes the opinion of GDC, based on the limited walkover, exploration and geological mapping of the landslide, observation of the landside conditions and the limited review of the subject references. This evaluation was performed in accordance with generally accepted local standards using that degree of care and skill ordinarily exercised under similar circumstances by reputable geotechnical consultants practicing in this or similar localities. No other warranty, expressed or implied, is made as to the professional advice included in this report. The conclusions for this project are, to a high degree dependent upon proper quality control from the contractor. Consequently, the recommendations are made contingent on the opportunity of GDC to observe the contractors operations including slurry, grouting or any excavating. If parties other than GDC are engaged to provide such services, they must be notified that they will be required to assume complete responsibility for the geotechnical phase of the project by concurring with the conclusions in this report or provide alternate recommendations as deemed appropriate.

(GDC) is pleased to present this letter to provide emergency recommendations related to the Poppy Trail Landslide of March 11, 2005. Our understanding of the project and recommendations are outlined below. We have not as yet performed any detailed geologic mapping, subsurface exploration, laboratory analyses or engineering calculations. Rather, our role has only been to advise the City on an emergency basis to aid in evaluating the overall safety of the subject slide and the affected residences. As such, this letter is based only on our observations, preliminary geologic reconnaissance, professional judgment, and a cursory review of published geologic reports and City records regarding the history of the subject slope. 1.0 SITE SUMMARY On March I1, 2005, GDC was contacted by Mr. Roger Vink of the Rolling Hills Homeowners Association to perform a site reconnaissance of a landslide that occurred the day before and advice the City regarding its condition. During the site reconnaissance on March 12. 2005, it was noted that a significant landslide had occurred that completely blocked Poppy Trail near Portuguese Bend Road, below #1 Poppy Trail guesthouse. The landslide overall measured about 300 feet long. 150 wide, with a head scarp of about 30 feet vertical below the lower graded pad of the guesthouse. Poppy Trail has been over -ridden by slide debris. To provide access to homeowners on Poppy Trail, the Home Owners Association was using a horse trail located down slope from the current road. • M 4k 4 N• r:=�1 �1:1 1'11111 • Resolution No. 996 11- GI:OUP r DELT:\ L-579 Group ncILi ('onvJLuua.

The slide has also displaced and removed a paved drainage swale near mid -slope. The head scarp falls Angeles County officials. within the guesthouse foundation, which has been exposed and red tagged by Los Many irrigation lines and concrete paved portion of the landslide. Irrigation lines, a guesthouse footing and wall debris were foundation head scarp. slope drains were noted in the central collector pipe for roof runoff next to the noticed in the area of the guesthouse Since the original site visit, local residents have constructed an access road below Poppy Trail which was covered with Crushed Miscellaneous Base (CMB). This new access road was used to drive the blocked residence automobiles into a safe area on the other side of the landside and to attempt to improve the road for All Terrain Vehicle (ATV) use. Lights have been stung along the trail with extension cords and florescent light bulbs. A water hose was found along the trail with water pressure. The hose was used for dust control and for the residences to attempt to achieve proper compaction of the sand and gravel. 2.0 SHORT-TERM RECOMMENDATIONS Currently, GDC is in the process of performing detailed mapping and drilling of the landslide. However, at your request and recognizing the emergency aspect of the situation, it is recommended that several steps be taken. 1. A small bulldozer should be used to seal the surface of the landslide mass where tension cracks have developed to prevent water infiltration and to remove the risk of someone slipping and/or falling. This can be achieved by pushing soil into the cracks and track rolling the soil to a tight compaction. 2. During the bulldozer grading the resulting surface should be sloped for drainage. Any large trees and brush on the slide should be cut and removed. The City should consider putting temporary fencing behind the head scarp and a catchment fence along the toe of the landslide. 3. With time and weather permitting, UV resistant plastic sheeting placed over the head scarp and in the two graben reas as a minimal action to prevent water from entering the landslide mass and to prevent erosion. The landslide should eventually be completely covered with the plastic extending over the edges of the landside. Drainage off of the plastic sheeting should be diverted away from the landslide to prevent water from accumulating on the landslide mass and to protect the temporary access road below Poppy Trail. Resolution No. 996 -12- l.(yv Clog) Delta Con.ulimas. 1,1c. Poppy Trail tanJ.hJ. 3 City or rolling Hdlt 4. Temporary measures should be installed to divert any water collected on the paved slope ditches. Sand bags, a makeshift catch basin made of sand bags in a shallow pit and a corrugated metal or PVC pipe or an "industrial sock drain" could be used for this purpose. The drainage devices should convey collected water down the slope away from the Iandside mass. Care should be taken to convey the water beyond the current access road and not to allow the water to enter the toe of the landslide. 5. A more complete inspection should be made of the areas above the landslide around the guesthouse and tennis court areas. Measures should be taken to prevent any runoff from the properties above from draining onto the landslide. This includes runoff from the roofs, into drain inlets and into paved or unpaved ditches since the outlets are unknown at this time. This may include use of sandbags, installation of temporary pipes, plastic sheeting, temporary re -grading, (which could require removal of driveways) and even redirecting the roof gutter down spouts into pipe systems and diverted away from the landslide mass. 6.

(GDC) is pleased to present this letter to provide pre -construction and winterization for construction recommendations related to the construction of the ATV road across the Poppy Trail Landslide and the lower access road. Currently, GDC is in the process of installing inclinometers in the landslide and observed the following: On September 1, 2005, during while installing inclinometers on the midsection of the Poppy Trail Landslide, it was observed that the landslide was still moving, as evidence by, there were traverse cracks that paralleled the toe of the landslide throughout the midsection of the landslide. Diagonal tension/shear cracks were observed along the north lateral scarp and across the northern section of George FF Canyon Trail where the trail crosses the lateral scarp of the landslide. Also, there is evidence that surface water has ran off the top of the landslide head scarp onto the landside mass. This water needs to be prevented from flov:ing onto the landslide where it can enter the new tension cracks, which can accelerate the movement of the landslide. t' • www.GrounDelta.corrt♦ GROUP DELTA tt.J. 1kt' u61 L-599 D Group Delta Consultants. Inc. Poppy Tr2iI Lan'dSIidc City of Rolling Hills PRE -CONSTRUCTION AND WINTERIZATION RECOMMENDATIONS Recognizing the emergency aspect of pre -construction of the proposed roadways and winterization of the Poppy Trail Landslide, it is recommended that several steps be taken during the construction of the ATV and the temporary access roads. 1. A small bulldozer should be used to seal the renewed tension cracks that developed to prevent water infiltration. At this time, the cracks are small but with time they could grow larger. This can be achieved by pushing soil into the cracks and track rolling the soil to a tight compaction. The toe of the landslide should be compacted with a bulldozer to seal any fractures and loose soil materials. 2. The guesthouse and landslide head scarp pose an emanate danger .to persons traveling on the AN and temporary access road. Therefore the guesthouse should be demolished. The demolition debris should not be stockpiled above the head scarp but taken offsite. After the guesthouse is removed, the landslide head scarp should be flattened to 1 horizontal to 1 to reduce rock and debris fall hazards from the scarp. A temporary fence should be placed on the uphill side of the ATV road to catch any debris that may fall from above the head scarp. The fence may not be suitable for retaining large boulders or debris. 3. Before the rainy season, UV resistant plastic sheeting should be placed over the head scarp to the ATV road and from the ATV road over the toe of the landslide to prevent water from entering the landslide mass and to prevent erosion. After the abandonment of the ATV road, the landslide should eventually be completely covered with the plastic extending over the edges of the landside and from the laidback head scarp to the toe. Drainage off the plastic sheeting should be diverted away from the landslide to prevent water from accumulating on the landslide mass and to protect the temporary access road below Poppy Trail. 4. Temporary measures should be installed to divert any water collected on the paved slope ditches and drainage areas above the head scarp. Sand bags, a makeshift catch basin made of sand bags in a shallow pit and a corrugated metal or PVC pipe or an "industrial sock drain" could be used for this purpose. The drainage devices should convey collected water down the slope away from the landside mass. Care should be taken to convey the water beyond the current access road 'and not to allow the water to enter the toe of the landslide. 5. A more complete inspection should be made of the areas above the landslide around the guesthouse and tennis court areas. Measures should L-599 1)1 Group Delia Consultants.

This includes runoff from the roofs, into drain inlets and into paved or unpaved ditches since the outlets are unknown at this time. This may include use of sandbags, installation of temporary pipes, plastic sheeting, temporary re -grading, (which could require removal of driveways) and even redirecting the roof gutter down spouts into pipe systems and diverted away from the landslide mass. As part of the pre -construction phase of this grading, GDC is installing 3 inclinometers to monitor landslide movement during grading. This data will help determine the stability of the landslide. Closure This letter summarizes the opinion of GDC, based on the limited walkover, exploration and geological mapping of the landslide, observation of the landside conditions and the limited review of the subject references. This evaluation was performed in accordance with generally accepted local standards using that degree of care and skill ordinarily exercised under similar circumstances by reputable geotechnical consultants practicing in this or similar localities. No other warranty, expressed or implied, is made as to the professional advice included in this report. The conclusions for this project are, to a high degree dependent upon proper quality control from the contractor. Consequently, the recommendations are made contingent on the opportunity of GDC to observe the contractors operations including slurry, grouting or any excavating. If parties other than GDC are engaged to provide such services, they must be notified that they will be required to assume complete responsibility for the geotechnical phase of the project by concurring with the conclusions in this report or provide alternate recommendations as deemed appropriate.

(GDC) is pleased to present this letter to provide emergency recommendations related to the Poppy Trail Landslide of March 11, 2005. Our understanding of the project and recommendations are outlined below. We have not as yet performed any detailed geologic mapping, subsurface exploration, laboratory analyses or engineering calculations. Rather, our role has only been to advise the City on an emergency basis to aid in evaluating the overall safety of the subject slide and the affected residences. As such, this letter is based only on our observations, preliminary geologic reconnaissance, professional judgment, and a cursory review of published geologic reports and City records regarding the history of the subject slope. 1.0 SITE SUMMARY On March 11, 2005, GDC was contacted by Mr. Roger Vink of the Rolling Hills Homeowners Association to perform a site reconnaissance of a landslide that occurred the day before and advice the City regarding its condition. During the site reconnaissance on March 12, 2005, it was noted that a significant landslide had occurred that completely blocked Poppy Trail near Portuguese Bend Road, below #1 Poppy Trail guesthouse. The landslide overall measured about 300 feet long, 150 wide, with a head scarp of about 30 feet vertical below the lower graded pad of the guesthouse. Poppy Trail has been over -ridden by slide debris. To provide access to homeowners on Poppy Trail, the Home Owners Association was using a horse trail located down slope from the current road. 4. • 4 \' WWGT ii ipi )e f t:f.cc't n 4. L-599 C;roop Delta Con:gult:tots. Inc. The slide mass has numerous fractures, mostly in the central portion, that were observed to extend depths estimated to be up to 20 feet deep. The slide has also displaced and removed a paved drainage swale near mid -slope. The head scarp falls Angeles County officials. within the guesthouse foundation, which has been exposed and red tagged by Los Many irrigation lines and concrete paved portion of the landslide. Irrigation lines, a guesthouse footing and wall debris were foundation head scarp. Poppy Trail Land'lidc City of Rolling Ilills slope drains were noted in the central collector pipe for roof runoff next to the noticed in the area of the guesthouse Since the original site visit, local residents have constructed an access road below Poppy Trail which was covered with Crushed Miscellaneous Base (CMB). This new access road was used to drive the blocked residence automobiles into a safe area on the other side of the landside and to attempt to improve the road for All Terrain Vehicle (ATV) use. Lights have been stung along the trail with extension cords and florescent light bulbs. A water hose was found along the trail with water pressure. The hose was used for dust control and for the residences to attempt to achieve proper compaction of the sand and gravel. 2.0 SHORT-TERM RECOMMENDATIONS Currently, GDC is in the process of performing detailed mapping and drilling of the landslide. However, at your request and recognizing the emergency aspect of the situation, it is recommended that several steps be taken. 1. A small bulldozer should be used to seal the surface of the landslide mass where tension cracks have developed to prevent water infiltration and to remove the risk of someone slipping and/or falling. This can be achieved by pushing soil into the cracks and track rolling the soil to a tight compaction. 2. During the bulldozer grading the resulting surface should be sloped for drainage. Any large trees and brush on the slide should be cut and removed. The City should consider putting temporary fencing behind the head scarp and a catchment fence along the toe of the landslide. 3. With time and weather permitting; UV resistant plastic sheeting should be placed over the head scarp and in the two graben areas as a minimal action to prevent water from entering the landslide mass and to prevent erosion. The landslide should eventually be completely covered with the plastic extending over the edges of the landside. Drainage off of the plastic sheeting should be diverted away from the landslide to prevent water from accumulating on the landslide mass and to protect the temporary access road below Poppy Trail.

Sand bags, a makeshift catch basin made of sand bags in a shallow pit and a corrugated metal or PVC pipe or an "industrial sock drain" could be used for this purpose. The drainage devices should convey collected water down the slope away from the Iandside mass. Care should be taken to convey the water beyond the current access road and not to allow the water to enter the toe of the landslide. 5. A more complete inspection should be made of the areas above the landslide around the guesthouse and tennis court areas. Measures should be taken to prevent any runoff from the properties above from draining onto the landslide. This includes runoff from the roofs, into drain inlets and into paved or unpaved ditches since the outlets are unknown at this time. This may include use of sandbags, installation of temporary pipes, plastic sheeting, temporary re -grading, (which could require removal of driveways) and even redirecting the roof gutter down spouts into pipe systems and diverted away from the landslide mass. 6. NOTE: The top of the slide is a near vertical slope about 30 feet high. This scarp is highly unstable and care should taken during any bulldozer work, plastic sheeting or sandbagging to not further de -stabilize the scarp, or endanger personnel by working too close to the top or bottom of the scarp. As part of the first phase of this emergency, GDC will drill 2 to 3 bucket auger holes. Since the landside might not be accessible, the borings will be drilled below the landslide to determine the stability of the temporary access road and on Poppy Trail. This data will help determine the soil and rock quality and if the site is on a larger landslide. Aerial photos will be analyzed as part of this first phase. Cross -sections would be drawn based on the mapping, down -hole logging and observed landslide geometry. This data will be used to select locations and depths for borings.

Diagonal tension/shear cracks were observed along the north lateral scarp and across the northern section of George FF Canyon Trail where the trail crosses the lateral scarp of the landslide. Also, there is evidence that surface water has ran off the top of the landslide head scarp onto the landside mass. This water needs to be prevented from flowing onto the landslide .here it can enter the new tension cracks, which can accelerate the movement of the landslide.

Currently, GDC is in the process of installing inclinometers in observed the following: pleased to present for construction across the Poppy the landslide and On September 1, 2005, during while installing inclinometers on the midsection of the . Poppy Trail Landslide, it was observed that the landslide was still moving, as evidence by, there were traverse cracks that paralleled the toe of the landslide throughout the midsection of the landslide. Diagonal tension/shear cracks were observed along the north lateral scarp and across the northern section of Georg Canyon Trail where the trail crosses the lateral scarp of the landslide. Also h e FF evidence that surface water has ran off the top of the landslide head scarp ontorthis e landside mass. This water needs to be prevented from flowing onto the landslide where it can enter the new tension cracks, which can accelerate the movement of the landslide. :i . • !rwv.l.1`�i 5•.j.1y;%•♦ Iti ;1' .:'•• ., 41• • i•!. .ji [ lia ♦www.Gr01 '� i[• .' ♦ tpD el taacom♦ • CROUP DELTA ri..Jit i r.UL L-599 1)1 Group Della Comulinnts. Inc. PRE -CONSTRUCTION AND WINTERIZATION RECOMMENDATIONS Recognizing the emergency aspect of pre -construction of the proposed roadways and winterization of the Poppy Trail Landslide, it is recommended that several steps be taken during the construction of the ATV and the temporary access roads. 1. A small bulldozer should be used to seal the renewed tension cracks that developed to prevent water infiltration. At this time, the cracks are small but with time they could grow larger. This can be achieved by pushing soil into the cracks and track rolling the soil to a tight compaction. The toe of the landslide should be compacted with a bulldozer to seal any fractures and loose soil materials. Poppy Trail Land Iidc Ciiy of Roping l8lls 2. The guesthouse and landslide head scarp pose an emanate danger to persons traveling on the ATV and temporary access road. Therefore the guesthouse should be demolished. The demolition debris should not be stockpiled above the head scarp but taken offsite. After the guesthouse is removed, the landslide head scarp should be flattened to 1 horizontal to 1 to reduce rock and debris fall hazards from the scar p. A temporary fnce should be placed on the uphill side of the ATV road to catch any debris that may fall from above the head scarp. The fence may not be suitable for retaining large boulders or debris. 3. Before the rainy season, UV resistant plastic sheeting should be placed over the head scarp to the ATV road and from the AN road over the toe of the landslide to prevent water from entering the landslide mass and to prevent erosion. After the abandonment of the AN road, the landslide should eventually be completely covered with the plastic extending over the edges of the Iandside and from the laidback head scarp to the toe. Drainage off the plastic sheeting should be diverted away from the landslide to prevent water from accumulating on the landslide mass and to protect the temporary access road below Poppy Trail. 4. Temporary measures should be installed to divert any water collected on the paved slope ditches and drainage areas above the head scarp.

(GDC) is pleased to present this letter to provide emergency recommendations related to the Poppy Trail Landslide of March 11, 2005. Our understanding of the project and recommendations are outlined below. We have not as yet performed any detailed geologic mapping, subsurface exploration, laboratory analyses or engineering calculations. Rather, our role has only been to advise the City on an emergency basis to aid in evaluating the overall safety of the subject slide and the affected residences. As such, this letter is based only on our observations, preliminary geologic reconnaissance, professional judgment, and a cursory review of published geologic reports and City records regarding the history of the subject slope. 1.0 SITE SUMMARY On March 11, 2005, GDC was contacted by Mr. Roger Vink of the Rolling Hills Homeowners Association to perform a site reconnaissance of a landslide that occurred the day before and advice the City regarding its condition. During the site reconnaissance on March 12, 2005, it was noted that a significant landslide had occurred that completely blocked Poppy Trail near Portuguese Bend Road, below 1 Poppy Trail guesthouse. The landslide overall measured about 300 feet long, 150 wide, with a head scarp of about 30 feet vertical below the lower graded padof the guesthouse. Poppy Trail has been over -ridden by slide debris. To provide access to homeowners on Poppy Trail, the Home Owners Association was usin a horse trail located down slope from the current road. 9 - • GROUP DI=I_TA L-599 C;ronp Delta Con.ultants.

This new access road was used to drive the blocked residence automobiles into a safe area on the other side of the landside and to attempt to improve the road for !w l Vehicle (ATV) use. Lights have been stung along the trail with extension cordsl and florescent light bulbs. A water hose was found along the trail with and The hose was used for dust control and for the residences to attempt to assure. proper compaction of the sand and gravel. P achieve 2.0 SHORT-TERM RECOMMENDATIONS Currently, GDC is in the process of performing detailed mapping and landslide. However, at your request and recognizing the emergency aspleCt of the situation, it is recommended that several steps be taken. P t of the 1. A small bulldozer should be used to seal the surface of the landslide mass where tension cracks have developed to prevent water infiltration and rennlove the risk of someone slipping and/or falling. This can be achieved by pushing soil into the cracks and track rolling the soil to a tight com i pa ctlon. 2. During the bulldozer grading the resulting surface should be slo e drainage. Any large trees and brush on the slide should P d nor be removed. The City should consider putting temp ora n cut aed head scarp and a catchment fence along the toe of the landslide. behind the 3. With time and weather permitting; CIV resistant plastic sheeting placed over the head scarp and in the two graben areas as aminimalshould be to prevent water from entering the landslide mass and to prevent erosioo. The landslide should eventually be completely covered with n. extending over the edges of the landside. Drainage off lof the plastic sheeting should be diverted away from the landslide to prevent water accumulating on the landslide mass and to protect the temporary a os road below Poppy Trail. P ry acccess Group Dclt:t Cnn>ult:uus. Inc. 3 poppy Trail 1.:mdlidc City of 12ol6c11111s 4. Temporary measures should be installed to divert any water ll paved slope ditches. Sand bags, a makeshift catch basin made of sand bags in a shallow pit and a corrugated metal or PVC pipe or an "industrial sock drain" could be used for this purpose. The drainage devices should convey collected water down the slope away from the Iandside mass. Care should be taken to convey the water beyond the current access road and not to allow the water to enter the toe of the landslide. 5. A more complete inspection should be made of the areas above the landslide around the guesthouse and tennis court areas. Measures should be taken to prevent any runoff from the properties above from draining onto the landslide. This includes runoff from the roofs, into drain inlets andinto paved or unpaved ditches since the outlets are unknown at this time. This may include use of sandbags, installation of temporary pipes, plastic sheeting, temporary re -grading, (which could require removal of driveways) and even redirecting the roof gutter down spouts into pipe systems and diverted away from the landslide mass. 6. NOTE: The to of the slide is a near vertical slo e about 30 feet hi h. This scar is hi hl unstable and care should taken durin an bulldozer work lastic sheetin or sandba in to not further de -stabilize the scar or endan er ersonnel by workin too close to the to or bottom of the scarp. As part of the first phase of this emergency, GDC will drill 2 to 3 bucket auger holes. Since the Iandside might not be accessible, the borings will be drilled below the landslide to determine the stability of the temporary access road and on Poppy Trail. This data will help determine the soil and rock quality and if the site is on a larger landslide. Aerial photos will be analyzed as part of this first phase. Cross -sections would be drawn based on the mapping, down -hole logging and observed landslide geometry. This data will be used to select locations and depths for borings. GROUT' etp.� c,• r IDELT:\.

COLLINS LAW FIRM The Aon Center 707 Wilshire Blvd., Suite 4880 Los Angeles, CA 90017 SUBJECT: NUISANCE ABATEMENT COSTS Dear Mr. Sheen and Mr. Collins: At the regular City Council meeting held on September 26, 2005, the City Council declared a public nuisance on the property at 1 Poppy Trail and required specific corrective actions to be completed by the property owner of 1 Poppy Trail. These actions are described in the attached correspondence. Required actions were not taken by the property owner, therefore, after appropriate notification to the property owner, and after issuance of an abatement warrant by the Superior Court, the City initiated and completed the nuisance abatement. Rolling Hills Municipal Code Section 8.24.060 requires the City to notify the property owner that this nuisance has been abated by the City and provide the cost of the abatement. The cost bill for abatement is attached. The enclosed cost bill will be presented to the City Council for approval at its regular meeting of Monday, April 10, 2006, at 7:30 p.m. in the Rolling Hills City Council Chambers, 2 Portuguese Bend Road. You are invited to attend this meeting and offer any comments or objections you may have to the bill. The Council may approve the enclosed cost bill, or make any modifications to it as may be appropriate. Pursuant to Rolling Hills Municipal Code Section 8.24.070, you are required to pay the cost bill approved by the Council, if any, in full within ten (10) days of Council approval. rJ ® Pr nt t•rl On Hr.( y, Ii:d Page 2 Thank you for your cooperation.

Inc. PRE -CONSTRUCTION AND WINTERIZATION RECOMMENDATIONS Recognizing the emergency aspect of pre -construction of the proposed roadways and winterization of the Poppy Trail Landslide, it is recommended that several sieps be taken during the construction of the ATV and the temporary access roads. 1. A small bulldozer should be used to seal the renewed tension cracks that developed to prevent water infiltration. At this time, the cracks are small but with time they could grow larger. This can be achieved by pushing soil into the cracks and track rolling the soil to a tight compaction. The toe of the landslide should be compacted with a bulldozer to seal any fractures and loose soil materials. Poppy Tr2i1 Lrrngdc City of Rollingillrc 2. The guesthouse and landslide head scarp persons traveling on the ATV and temporary access road emanatedanger the guesthouse should be demolished. The demolition debris should f not be stockpiled above the head scarp but taken offsite. After the guesthouse is removed, the landslide head scarp should be flattened to 1 horizontal to 1lo reduce rock and debris fall hazards from the scar p. A temporary fence should be placed on the uphill side of the ATV road to catch any debris ad may fall from above the head scarp. The fence may not be suitable for retaining large boulders or debris. 3_ Before the rainy season, UV resistant plastic sheeting should be placed ovEr the head scarp to the ATV road and from the ATV road over the toe of the landslide to prevent water from entering the landslide mass and to prevent erosion. After the abandonment of the ATV road, the landslide should eventually be completely covered with the plastic extending over the edges of the landside and from the laidback head scarp to the toe. Drainage off the plastic sheeting should be diverted away from the landslide to prevent water frorn accumulating on the landslide mass and to protect the temporary access road below Poppy Trail 4. Temporary measures should be installed to divert any water collected on the paved slope ditches and drainage areas above the head scarp. Sand bags, a makeshift catch basin made of sand bags in a shallow pit and a corrugated metal or PVC pipe or an "industrial sock drain" could be used for this purpose. The drainage devices should convey collected water down the slope away from the landside mass. Care should be taken to convey the water beyond the current access road 'and not to allow the water to enter the toe of the landslide. 5. A more complete inspection should be made of the areas above the landslide around the guesthouse and tennis court areas. Measures should DELTA r, L-599 1)1 LGroup -599 ncli_ Cansuh;:ms.

(GDC) is pleased to present this letter to . provide emergency recommendations related to " the Po Landslide of March 11, 2005. Our understanding the project Trail recommendations are outlined below. We have not as yet performed any y d and detailed geologic mapping, subsurface exploration, laboratory analyses or en ineeun calculations. Rather, our role has only been to advise the City on an e g y merbasis to aid in evaluating the overall safety of. the subject slide and the affected residences. As such, this letter is based only on our observations, preliminary geologic reconnaissance, professional judgment, and a cursory review of published geologic reports and City records regarding the history of the subject slope. P- 1.0 SITE SUMMARY On March 11, 2005, GDC was contacted by Mr. Roger Vink of the Rollin His Homeowners Association to perform a site reconnaissance of a landslide that occurred the day before and advice the City regarding its condition. During the i reconnaissance on March 12, 2005, it was noted that a significant landslide had occurred that completely blocked Poppy Trail near Portuguese Bend Road, below 1 Poppy Trail guesthouse. The landslide overall measured about 300 feet long, 150 wide, with a head scarp of about 30 feet vertical below the lower graded padof the guesthouse. Poppy Trail has been over -ridden by slide debris. To r access to homeowners on Poppy provide Trail, the Home Owners Association was using a horse trail located down slope from the current road.

This declared public nuisance resulted from a landslide event that occurred on March 5-6, 2005. Corrective actions required to be completed by the owner of #1 Poppy Trail included the following: 1. Seal renewed tension cracks to prevent water infiltration. 2. Demolish the guesthouse and remove all debris from the site. 3. Flatten headscarp to 1:1 slope. 4. Cover entire affected area with UV resistant plastic sheeting. 5. Install temporary drainage devices to divert stormwater from entering landslide area from locations above the headscarp of the landslide. The property owner of #1 Poppy Trail was provided appropriate legal notice of this declaration and ordered to provide a plan and schedule of implementing the nuisance abatement mitigation measures no later than October 6, 2005 and commence implementation of the plan and performance of the corrective mitigation measures on or before, but no later than, October 10, 2005 and complete the corrective mitigation measures no later than 4:00 p.m. November 10, 2005. By November 10, 2005 the corrective measures had not commenced and had not been completed.

The change from the original invoice sent on March 1, 2006, includes a charge of $3,454.60 for required soil, testing for removal of the soil in flattening the headscarp to 1:1 slope. Therefore; total costs for the nuisance abatement that is submitted to the City, Council for consideration of approval are $147,928.77.

Inc. PRE -CONSTRUCTION AND WINTERIZATION RECOMMENDATIONS Recognizing the emergency aspect of pre -construction of the proposed roadways and winterization of the Poppy Trail Landslide, it is recommended that several steps be taken during the construction of the ATV and the temporary access roads. I. A small bulldozer should be used to seal the renewed tension cracks that developed to prevent water infiltration. At this time, the cracks are small but with time they could grow larger. This can be achieved by pushing soil into the cracks and track rolling the soil to a tight compaction. The toe oldie loose soil materials. landslide should be compacted with a bulldozer to seal any fractures and 2. The guesthouse and landslide head scarp persons traveling on the ATV and temporary access road.nate Thedreforrerthe guesthouse should be demolished. The demolition debris should not be stockpiled above the head scarp but taken offsite. After is removed, the landslide head scarp should be flattened to I horizontal tosIe fo reduce rock and debris fall hazards from the scar p. A temporary fence should be placed on the ,uphill side of the ATV road to catch any debris that may fall from above the head scarp. The fence may not be suitable for retaining large boulders or debris. 3. Before the rainy season, UV resistant plastic sheeting should be placed OM the head scarp to the ATV road and from the ATV road over the toe of the landslide to prevent water from entering the landslide mass and to prevent erosion. After the abandonment of the ATV road, the landslide should eventually be completely covered with the plastic extending over the edges of the landside and from the laidback head scarp to the toe. Drainage off the plastic sheeting should be diverted away from the landslide to prevent water from accumulating on the landslide mass and to protect the temporary access road below Poppy Trail. 4. Temporary measures should be installed to divert any water collected on the paved slope ditches and drainage areas above the head scarp. Sand bags, a makeshift catch basin made of sand bags in a shallow pit and a corrugate a metal or PVC pipe or an "industrial sock drain" could be used forthis purpose. The drainage devices should convey collected water down the slope away from the landside mass. Care should be taken to convey the water beyond the current access road'and not to allow the water to enter the toe of the landslide. 5. A more complete inspection should be made of the areas above landslide around the guesthouse and tennis court areas.

During the site reconnaissance on March 12, 2005, it was noted that a significant landslide had occurred that completely blocked Poppy Trail near Portuguese Bend Road, below #1 Poppy Trail guesthouse. The landslide overall measured about 300 feet long, 150 wide, with a head scarp of about 30 feet vertical below the lower raded the guesthouse. Poppy Trail has been over -ridden by slide debris. To padof access to homeowners on Poppy provide Trail, the Home Owners Association was usinga horse trail located down slope from the current road. 41%WW.Grt,nrl)ch i.c��rn• Cl Ot;I' r DELTA 57.7rn-lirt-ccm L-599 Crimp Dihta,G•n>ult:nus.

In that correspondence, we requested that you implement these measures by September 15, 2005. To our knowledge, these measures have not been performed as of this date. We enclose updated safety mitigation recommendations from our consulting geologist that are necessary to be implemented on your property to help protect against aggravation of the existing landslide as we approach the rainy season. These mitigation measures are outlined in the attached letter dated September 1, 2005. Pursuant to Rolling Hills Municipal Code Section 8.24.020 ("Duty of Owner or Possessor of Property") "every person who owns or is in possession of any property, place or area within the boundaries of the City shall, at his or her own expense, maintain the property, place or area free from any nuisance." Rolling Hills Municipal Code Section 8.28.010 defines any condition on property that has or will aggravate, enlarge or accelerate an active landslide to be a public nuisance subject to abatement pursuant to Chapter 8.24. We have enclosed a copy of both Chapters 8.24 and 8.28 for your review. Pursuant to Section 8.24.030, you are hereby directed to implement the following measures in order to abate conditions on your property that will potentially aggravate and accelerate the existing landslide: 1. Seal renewed tension cracks to prevent water infiltration. 2. Demolish the guesthouse and remove all debris from the site. 3. Flatten headscarp to 1:1 slope. 4. Cover entire affected area with UV resistant plastic sheeting. 5. Install temporary drainage devices to divert stormwater from entering landslide area from locations above the head scarp of the landslide. The above measures must be implemented by September 15, 2005. You are hereby notified that if you do not implement the nuisance abatement actions by September 15, 2005, a nuisance abatement hearing will be conducted before the City Council at its regular meeting on Monday, September 26, 2005 beginning at 7:30 p.m. in the Rolling Hills City Council Chambers, 2 Portuguese Bend Road. If the hearing goes forward, you will be given an opportunity to present evidence to the City Council regarding the conditions on your property and regarding this abatement order. Pririted on Recycled Paper. Page 2 We have forwarded this correspondence to all of the known addresses we have regarding this property. We trust that by providing a certified letter to Mr. Craig Collins that he will forward this letter to you in the event that it is not received at the addresses listed above.

(GDC) is pleased to present this letter to provide pre -construction and winterization for construction recommendations related to the construction of the ATV road across the Poppy Trail Landslide and the lower access road. Currently, GDC is in the process of installing inclinometers in the landslide and observed the following: On September 1, 2005, during while installing inclinometers on the midsection of the Poppy Trail Landslide, it was observed that the landslide was still moving, as evidence by, there were traverse cracks that paralleled the toe of the landslide throughout the midsection of the landslide. Diagonal tension/shear cracks were observed along the north lateral scarp and across the northern section of George FF Canyon Trail where the trail crosses the lateral scarp of the landslide. Also, there is evidence that surface water has ran off the top of the landslide head scarp onto the landside mass. This water needs to be prevented from flowing onto the landslide where it can enter the new tension cracks, which can accelerate the movement of the landslide. 8www.Grou Delta coms. GROUP DELTA tkomktIL1: I1 L-599 D I Poppy Trail Landslide Group Delta Consultants. Inc. 2 City of Rolling Hills PRE -CONSTRUCTION AND WINTERIZATION RECOMMENDATIONS Recognizing the emergency aspect of pre -construction of the proposed roadways and winterization of the Poppy Trail Landslide, it is recommended that several steps be taken during the construction of the ATV and the temporary access roads. 1. A small bulldozer should be used to seal the renewed tension cracks that developed to prevent water infiltration. At this time, the cracks are small but with time they could grow larger. This can be achieved by pushing soil into the cracks and track rolling the soil to a tight compaction. The toe of the landslide should be compacted with a bulldozer to seal any fractures and loose soil materials. 2. The guesthouse and landslide head scarp pose an emanate danger to persons traveling on the ATV and temporary access road. Therefore the guesthouse should be demolished. The demolition debris should not be stockpiled above the head scarp but taken offsite. After the guesthouse is removed, the landslide head scarp should be flattened to 1 horizontal to 1 to reduce rock and debris fall hazards from the scarp. A temporary fence should be placed on the uphill side of the ATV road to catch any debris that may fall from above the head scarp. The fence may not be suitable for retaining large boulders or debris. 3. Before the rainy season, UV resistant plastic sheeting should be placed over the head scarp to the ATV road and from the ATV road over the toe of the landslide to prevent water from entering the landslide mass and to prevent erosion. After the abandonment of the ATV road, the landslide should eventually be completely covered with the plastic extending over the edges of the landside and from the laidback head scarp to the toe. Drainage off the plastic sheeting should be diverted away from the landslide to prevent water from accumulating on the landslide mass and to protect the temporary access road below. Poppy Trail. 4. Temporary measures should be installed to divert any water collected on the paved slope ditches and drainage areas above the head scarp. Sand bags, a makeshift catch basin made of sand bags in a shallow pit and a corrugated metal or PVC pipe or an "industrial sock drain" could be used for this purpose. The drainage devices should convey collected water down the slope away from the landside mass. Care should be taken to convey the water beyond the current access road and not to allow the water to enter the toe of the landslide. 5. A more complete inspection should be made of the areas above the landslide around the guesthouse and tennis court areas. Measures should L-599 DI Poppy Trail Landslide Group Delta Consultants. Inc. 3 City of Rolling Hills be taken to prevent any runoff from the properties above from draining onto the landslide. This includes runoff from the roofs, into drain inlets and into paved or unpaved ditches since the outlets are unknown at this time. This may include use of sandbags, installation of temporary pipes, plastic sheeting, temporary re -grading, (which could require removal of driveways) and even redirecting the roof gutter down spouts into pipe systems and diverted away from the landslide mass. As part of the pre -construction phase of this grading, GDC is installing 3 inclinometers to monitor landslide movement during grading. This data will help determine the stability of the landslide. Closure This letter summarizes the opinion of GDC, based on the limited walkover, exploration and geological mapping of the landslide, observation of the landside conditions and the limited review of the subject references. This evaluation was performed in accordance with generally accepted local standards using that degree of care and skill ordinarily exercised under similar circumstances by reputable geotechnical consultants practicing in this or similar localities. No other warranty, expressed or implied, is made as to the professional advice included in this report. The conclusions for this project are, to a high degree dependent upon proper quality control from the contractor. Consequently, the recommendations are made contingent on the opportunity of GDC to observe the contractors operations including slurry, grouting or any excavating. If parties other than GDC are engaged to provide such services, they must be notified that they will be required to assume complete responsibility for the geotechnical phase of the project by concurring with the conclusions in this report or provide alternate recommendations as deemed appropriate.

As such, this letter is based only on our observations, preliminary geologic reconnaissance, professional judgment, and a cursory review of published geologic reports and City records regarding the history of the subject slope. 1.0 SITE SUMMARY On March 11, 2005, GDC was contacted by Mr. Roger Vink of the Rolling Hills Homeowners Association to perform a site reconnaissance of a landslide that occurred the day before and advice the City regarding its condition. During the site reconnaissance on March 12, 2005, it was noted that a significant landslide had occurred that completely blocked Poppy Trail near Portuguese Bend Road, below #1 Poppy Trail guesthouse. The landslide overall measured about 300 feet long, 150 wide, with a head scarp of about 30 feet vertical below the lower graded pad of the guesthouse. Poppy Trail has been over -ridden by slide debris. To provide access to homeowners on Poppy Trail, the Home Owners Association was using a horse trail located down slope from the current road. 4 t 4 \5 aN.6.01:n!)-l::t<< 14 4 L ->9t) CROUP 1?l:l_T:\ AU:1,_4kt:t:tt•9 Gtouh Doha Consultants. Inc. Poppy Frail L:wd>IiJr City of Rolling Hills The slide mass has numerous fractures, mostly in the central portion, that were observed to extend depths estimated to be up to 20 feet deep. The slide has also displaced and removed a paved drainage swale near mid -slope. The head scarp falls within the guesthouse foundation, which has been exposed and red tagged by Los Angeles County officials. Many irrigation lines and concrete paved slope drains were noted in the central portion of the landslide. Irrigation lines, a collector pipe for roof runoff next to the guesthouse footing and wall debris were noticed in the area of the guesthouse foundation head scarp. Since the original site visit, local residents have constructed an access road below Poppy Trail which was covered with Crushed Miscellaneous Base, (CMB). This new access road was used to drive the blocked residence automobiles into a safe area on the other side of the landside and to attempt to improve the road for All Terrain Vehicle (A-110 use. Lights have been stung along the trail with extension cords and florescent light bulbs. A water hose was found along the trail with water pressure. The hose was used for dust control and for the residences to attempt to achieve proper compaction of the sand and gravel. 2.0 SHORT-TERM RECOMMENDATIONS Currently, GDC is in the process of performing detailed mapping and drilling of the landslide. However, at your request and recognizing the emergency aspect of the situation, it is recommended that several steps be taken. 1. A small bulldozer should be used to seal the surface of the landslide mass where tension cracks have developed to prevent water remove the risk of someone slipping and/or falling. This can be achieved by pushing soil into the cracks and track rolling the soil to a tight compaction. 2. During the bulldozer grading the resulting surface should be sloped for drainage. Any large trees and brush on the slide should be cut and removed. The City should consider putting temporary fencing behind the head scarp and a catchment fence along the toe of the landslide. 3. With time and weather permitting, UV resistant plastic sheeting should be placed over the head scarp and in the two graben areas as a minimal action to prevent water from entering the landslide mass and to prevent erosion. The landslide should eventually be completely covered with the plastic extending over the edges of the landside. Drainage off of the plastic sheeting should be diverted away from the landslide to prevent waterfrom accumulating on the landslide mass .and to protect the temporary access road below Poppy Trail. L -5Y) Group Delta Con>ultants. Inc. i Poppy Trail I_and'lrlc Cite nr Rollin" Hills 4. Temporary measures should be installed to divert any water collected on the paved slope ditches. Sand bags, a makeshift catch basin made of sand bags in a shallow pit and a corrugated metal or PVC pipe or an "industrial sock drain" could be used for this purpose. The drainage devices should convey collected water down the slope away from the Iandside mass. Care should be taken to convey the water beyond the current access road and not to allow the water to enter the toe of the landslide. 5. A more complete inspection should be made of the areas above the landslide around the guesthouse and tennis court areas. Measures should be taken to prevent any runoff from the properties above from draining onto the landslide. This includes runoff from the roofs, into drain inlets and into paved or unpaved ditches since the outlets are unknown at this time. This may include use of sandbags, installation of temporary pipes, plastic sheeting, temporary re -grading, (which could require removal of driveways) and even redirecting the roof gutter down spouts into pipe systems and diverted away from the landslide mass. 6. NOTE: The top of the slide is a near vertical slope about 30 feet high. This scarp is highly unstable and care should taken during any bulldozer work, plastic sheeting or sandbagging to not further de -stabilize the scarp, or endanger personnel by working too close to the top or bottom of the scarp. As part of the first phase of this emergency, GDC will drill 2 to 3 bucket auger holes. Since the landside might not be accessible, the borings will be drilled below the landslide to determine the stability of the temporary access road and on Poppy Trail. This data will help determine the soil and rock quality and if the site is on a larger landslide. Aerial photos will be analyzed as part of this first phase. Cross -sections would be drawn based on the mapping, down -hole logging and observed landslide geometry. This data will be used to select locations and depths for borings.

PUBLIC NUISANCE ANDORDERINGTHE ABATEMENT THEREOF. THE CITY COUNCIL OF' THE CITY OF ROLLING HILLS DOES HEREBY FIND DECLARE AND ORDER AS FOLLOWS: Section 1. Pursuant to Section 8.24.030 of the Rolling Hills Municipal Code, the City Manager notified Mr. Alan Sheen, owner of that certain real property in the City of Rolling Hills commonly known as 1 Poppy Trail (Lot 90-B-RH), to abate conditions on his property that would potentially aggravate andaccelerate an existing landslide. The measures include sealing renewed tension cracks to prevent water infiltration, demolishing the guesthouse and removing all debris from the site, flattening the headscarp to -a 1:1 slope, covering the entire affected area with UV resistant plastic sheeting, and installing temporary drainage devices to divert stormwater from entering the landslide, area from locations above the headscarp of the landslide. The notice directed that the measures be taken within 15 days of the date of the notice, otherwise the City Council would hold a public hearing on September 26, 2005 in the City Council Chambers of City Hallto hear any protests the owner might have to. the abatement of the nuisance. On September2, 2005 the City posted .a notice of substandard property at the site apprising the property owners of the unsafe and unsightly conditions that exist on the property. Section 2. No, action to abate the nuisance has been taken by the property owner. Consequently, onSeptember 26, 2005, the City Council held a public hearing to allow the City Manager, the property owner and: any other interested parties to testify and submit evidence regarding the condition of the property located at 1 Poppy Trail. The property owner did not attend the public hearing. The property owner's attorney, _Craig Collins was present and ' participated in the hearing. Section 3. Based upon staff reports, related documents and the evidence' presented at the time of the hearing, the City Council makes the following findings of fact: a. The property located at 1 Poppy Trail is located in an active landslide in the. City of Rolling Hills. The property is improved witha single family residence, swimming pool, water feature, stable, tennis court and illegal nonconforming guesthouse. Inspections of theproperty demonstrate that the single family residence and:: guesthouse are presently uninhabited. b. Following the activation of the landslide in early 2005, a geologist engaged by the City, with the property owner's permission, conducted borings and other tests on the property to better understand the structure of the landslide in order to enable all. interested parties to evaluate their options. A copy of the geologist's report was provided to the owner of 1 Poppytrail. c. Currently, the foundation of the guesthouse is exposed from below and rests at the top of the active landslide. The guesthouse's concrete foundation was damaged in the landslide, and it continues to suffer damage as the ground moves. The guesthouse was red -tagged as unsafe to occupy by the County of Los Angeles on March 7, 2005 and in its current condition, it cannot be used; further it is unsightly and causes visual blight. Due to its location in.a: landslide, its condition will only worsen, and with additional rain will likely fall into the canyon. Hence, the guesthouse represents a danger to residents, adjoining properties, public utilities, roads and trails. d. ' The driveway on the property has major cracks and portionsare directly involved in the landslide. Irrigation and drainage pipes areopen and exposed and non-functional. The exposed drainage devices, exposed headscarp of the landslide and. unmodified headscarp will: permit the intrusion of water into the landslide, that will continue:. to adversely impact the stability of 1 Poppytrail as well as that of surrounding properties, roads and"trails. e. All of the foregoing together or separately, as further described in the attached correspondence (Exhibit A) represent a public nuisance and a threat to public safety. Section 5. On the basis of the foregoing, and of the evidence contained in the record, the City Council finds and determines that the landslide ,condition of the property at 1 Resolution No. 996 -1- Poppytrail, the condition of the guesthouse, the open crevices and fissures, and the exposed irrigation and drainage pipes and facilities separately and collectively constitute a public nuisance within the meaning of Sections 8.24.010 arid 8.28.010 of the Municipal Code, and constitute a condition that is injurious to the public health, safety and welfare. The City Council further finds that by allowing the above described conditions to remain unabated through the 2005-2006 winter rainy season, stormwater will further infiltrate the landslide and will further destabilize the property and the guesthouse, creating a danger to persons and property in the area. Section 6. In accordance with theforegoing, and because it is the duty of property owners to maintain their properties free of nuisances, the City Council orders that the property owner prepare and submit a written plan to the City within ten (10) days of the adoption of this Resolution providing for implementation of the corrective winterization measures described in Section 1 of this Resolution and further described in the attached correspondence (Exhibit A); further, that the property owner commence implementation of the plan and performance of the corrective measures on or before October 10, 2005; and, that the corrective measures be completed by the property owner on or before November 10, 2005. In the event that the property owner fails to submit a plan and/or fails to commence performance of the corrective measures by the above -described deadlines, than the City may, on or after October 26, 2005 perform the corrective measures at the property owner's expense as authorized in Section 8.24.060 of the Municipal Code. Section 7. In the nuisance is not abated as specified herein, then the City Manager is directed to cause the nuisance to be abated by the City, and also is directed to notify the property owner in writing by certified mail and regular mail of the cost of removal of the nuisance and that payment in full for removal of the nuisance is due to the City within 10 days of the date of mailing of the notice. If the total cost of abating the nuisance is not paid to the City within 10 days after the date of the notice, the City Clerk shall record, in the Office of the County Recorder, a statement of the total balance due to the City, which shall constitute a lien upon the property. Section 8. The City Clerk is hereby directed to send a copy of this resolution by certified and regular mail to the owner of the property located at 1 Poppy Trail. Section 9. This resolution shall take effect immediately on September 26, 2005. PASSED, APPROVED AND ADOPTED THIS 26th DAY OF SEPT Godfrey Pe e Mayor ATTEST: Craig R.

Diagonal tension/shear cracks were observed along the north lateral scarp and across the northern section of George FF Canyon Trail where the trail crosses the lateral scarp of the landslide. Also, there is evidence that surface water has ran off the top of the landslide head scarp onto the Iandside mass.

PRE -CONSTRUCTION AND WINTERIZATION RECOMMENDATIONS Poppy Trail Landslide City of Rolling Hills Recognizing the emergency aspect of pre -construction of the proposed roadways and winterization of the Poppy Trail Landslide, it is recommended that several steps be taken during the construction of the ATV and the temporary access roads. 1. A small bulldozer should be used to seal the renewed tension cracks that developed to prevent water infiltration. At this time, the cracks are small but with time they could grow larger. This can be achieved by pushing soil into the cracks and track rolling the soil to a tight compaction. The toe of the landslide should be compacted with a bulldozer to seal any fractures and loose soil materials. 2. The guesthouse and landslide head scarp pose an emanate danger to persons traveling on the ATV and temporary access road. Therefore the guesthouse should be demolished. The demolition debris should not be stockpiled above the head scarp but taken offsite. After the guesthouse is removed, the landslide head scarp should be flattened to 1 horizontal to 1 to reduce rock and debris fall hazards from the scarp. A temporary fence should be placed on the uphill side of the ATV road to catch any debris that may fall from above the head scarp. The fence may not be suitable for retaining large boulders or debris. 3. Before the rainy season, UV resistant plastic sheeting should be placed over the head scarp to the ATV road and from the ATV road over the toe of the landslide to prevent water from entering the landslide mass and to prevent erosion. After the abandonment of the ATV road, the landslide should eventually be completely covered with the plastic extending over the edges of the landside and from the laidback head scarp to the toe. Drainage off the plastic sheeting should be diverted away from the landslide to prevent water from accumulating on the landslide mass and to protect the temporary access road below Poppy Trail. 4. Temporary measures should be installed to divert any water collected on the paved slope ditches and drainage areas above the head scarp. Sand bags, a makeshift catch basin made of sand bags in a shallow pit and a corrugated metal or PVC pipe or an "industrial sock drain" could be used for this purpose. The drainage devices should convey collected water down the slope away from the landside mass. Care should be taken to convey the water beyond the current access road and not to allow the water to enter the toe of the landslide. 5. A more complete inspection should be made of the areas above the landslide around the guesthouse and tennis court areas. Measures should Resolution No. 996 L-599 DI Poppy Trail Landslide Group Delta Consultants. Inc. 3 City of Rolling Hills be taken to prevent any runoff from the properties above from draining onto the landslide. This includes runoff from the roofs, into drain inlets and into paved or unpavedditches since the outlets are unknown at this time. This may include use of sandbags, installation of temporary pipes, plastic sheeting, temporary re -grading, (which could require removal of driveways) and even redirecting the roof gutter down spouts into pipe systems and diverted away from the landslide mass. As part of the pre -construction phase of this grading, GDC is installing 3 inclinometers to monitor landslide movement during grading. This data will help determine the stability of the landslide. Closure This letter summarizes the opinion of GDC, based on the limited walkover, exploration and geological mapping of the landslide, observation of the landside conditions and the limited review of the subject references. This evaluation was performed in accordance with generally accepted local standards using that degree of care and skill ordinarily exercised under similar circumstances by reputable geotechnical consultants practicing in this or similar localities. No other warranty, expressed or implied, is made as to the professional advice included in this report. The conclusions for this project are, to a high degree dependent upon proper quality control from the contractor. Consequently, the recommendations are made contingent on the opportunity of GDC to observe the contractors operations including slurry, grouting or any excavating. If parties other than GDC are engaged to provide such services, they must be notified that they will be required to assume complete responsibility for the geotechnical phase of the project by concurring with the conclusions in this report or provide alternate recommendations as deemed appropriate.

Attn: Craig Nealis, City Manger Subject: Summary and Emergency Recommendations Geotechnical and Geological Evaluation Poppy Trail Landslide Rolling Hills, California Mr. Nealis: As requested, GROUP DELTA CONSULTANTS, INC. (GDC) is pleased to present this letter to provide emergency recommendations related to the Poppy Trail Landslide of March 11, 2005. Our understanding of the project and recommendations are outlined below. We have not as yet performed any detailed geologic mapping, subsurface exploration, laboratory analyses or engineering calculations. Rather, our role has only been to advise the City on an emergency basis to aid in evaluating the overall safety of the subject slide and the affected residences. As such, this letter is based only on our observations, preliminary geologic reconnaissance, professional judgment, and a cursory review of published geologic reports and City records regarding the history of the subject slope. 1.0 SITE SUMMARY On March 11, 2005, GDC was contacted by Mr. Roger Vink of the Rolling Hills Homeowners Association to perform a site reconnaissance of a landslide that occurred the day before and advice the City regarding its condition. During the site reconnaissance on March 12, 2005, it was noted that a significant landslide had occurred that completely blocked Poppy Trail near Portuguese Bend Road, below #1 Poppy Trail guesthouse. The landslide overall measured about 300 feet long, 150 wide, with a head scarp of about 30 feet vertical below the lower graded pad of the guesthouse. Poppy Trail has been over -ridden by slide debris. To provide access to homeowners on Poppy Trail, the Home Owners Association was using a horse trail located down slope from the current road. • Resolution No. 996 -11- L-599 Poppy Trail Landslide Group Delta Consultants. Inc. 2 City of Rolling Hills The slide mass has numerous fractures, mostly in the central portion, that were observed to extend depths estimated to be up to 20 feet deep. The slide has also displaced and removed a paved drainage swale near mid -slope. The head scarp falls within the guesthouse foundation, which has been exposed and red tagged by Los Angeles County officials. Many irrigation lines and concrete paved slope drains were noted in the central portion of the landslide. Irrigation lines, a collector pipe for roof runoff next to the guesthouse footing and wall debris were noticed in the area of the guesthouse foundation head scarp. Since the original site visit, local residents have constructed an access road below Poppy Trail which was covered with Crushed Miscellaneous Base (CMB). This new access road was used to drive the blocked residence automobiles into a safe area on the other side of the landside and to attempt to improve the road for All Terrain Vehicle (ATV) use. Lights have been stung along the trail with extension cords and florescent light bulbs. A water hose was found along the trail with water pressure. The hose was used for dust control and for the residences to attempt to achieve proper compaction of the sand and gravel. 2.0 SHORT-TERM RECOMMENDATIONS Currently, GDC is in the process of performing detailed mapping and drilling of the landslide. However, at your request and recognizing the emergency aspect of the situation, it is recommended that several steps be taken. 1. A small bulldozer should be used to seal the surface of the landslide mass where tension cracks have developed to prevent water infiltration and to remove the risk of someone slipping and/or falling. This can be achieved by pushing soil into the cracks and track rolling the soil to a tight compaction. 2. During the bulldozer grading the resulting surface should be sloped for drainage. Any large trees and brush on the slide should be cut and removed. The City should consider putting temporary fencing behind the head scarp and a catchment fence along the toe of the landslide. 3. With time and weather permitting, UV resistant plastic sheeting should be placed over the head scarp and in the two graben areas as a minimal action to prevent water from entering the landslide mass and to prevent erosion. The landslide should eventually be completely covered with the plastic extending over the edges of the landside. Drainage off of the plastic sheeting should be diverted away from the landslide to prevent water from GROUP accumulating on the landslide mass and to protect the temporary access road below Poppy Trail. DELTA r{•1&YU%L .j .1 Resolution No. 996 -12- L-599 Poppy Trail Landslide Group Delta Consultants. Inc. 3 City of Rolling Hills 4. Temporary measures should be installed to divert any water collected on the paved slope ditches. Sand bags, a makeshift catch basin made of sand bags in a shallow pit and a corrugated metal or PVC pipe or an "industrial sock drain" could be used for this purpose. The drainage devices should convey collected water down the slope away from the landside mass. Care should be taken to convey the water beyond the current access road and not to allow the water to enter the toe of the landslide. 5. A more complete inspection should be made of the areas above the landslide around the guesthouse and tennis court areas. Measures should be taken to prevent any runoff from the properties above from draining onto the landslide. This includes runoff from the roofs, into drain inlets and into paved or unpaved ditches since the outlets are unknown at this time. This may include use of sandbags, installation of temporary pipes, plastic sheeting, temporary re -grading, (which could require removal of driveways) and even redirecting the roof gutter down spouts into pipe systems and diverted away from the landslide mass. 6. NOTE: The top of the slide is a near vertical slope about 30 feet high. This scarp is highly unstable and care should taken during any bulldozer work, plastic sheeting or sandbagging to not further de -stabilize the scarp, or endanger personnel by working too dose to the top or bottom of the scarp. As part of the first phase of this emergency, GDC will drill 2 to 3 bucket auger holes. Since the landside might not be accessible, the borings will be drilled below the landslide to determine the stability of the temporary access road and on Poppy Trail. This data will help determine the soil and rock quality and if the site is on a larger landslide. Aerial photos will be analyzed as part of this first phase. Cross -sections would be drawn based on the mapping, down -hole logging and observed landslide geometry. This data will be used to select locations and depths for borings.

We enclose updated safety mitigation recommendations from our consulting geologist that are necessary to be implemented on your property to help protect against aggravation of the existing landslide as we approach the rainy season. These mitigation measures are outlined in the attached letter dated September 1, 2005. Pursuant to Rolling Hills Municipal Code Section 8.24.020 ("Duty of Owner or Possessor of Property") "every person who owns or is in possession of any property, place or area within the boundaries of the City shall, at his or her own expense, maintain the property, place or area free from any nuisance." Rolling Hills Municipal Code Section 8.28.010 defines any condition on property that has or will aggravate, enlarge or accelerate an active landslide to be a public nuisance subject to abatement pursuant to Chapter 8.24. We have enclosed a copy of both Chapters 8.24 and 8.28 for your review. Pursuant to Section 8.24.030, you are hereby directed to implement the following measures in order to abate conditions on your property that will potentially aggravate and accelerate the existing landslide: 1. Seal renewed tension cracks to prevent water infiltration. 2. Demolish the guesthouse and remove all debris from the site. 3. Flatten headscarp to 1:1 slope. 4. Cover entire affected area with UV resistant plastic sheeting. 5. Install temporary drainage devices to divert stormwater from entering landslide area from locations above the head scarp of the landslide. The above measures must be implemented by September 15, 2005. You are hereby notified that if you do not implement the nuisance abatement actions by September 15, 2005, a nuisance abatement hearing will be conducted before the City Council at its regular meeting on Monday, September 26, 2005 beginning at 7:30 p.m. in the Rolling Hills City Council Chambers, 2 Portuguese Bend Road.

Currently, GDC is in the process of installing inclinometers in the landslide and observed the following: On September 1, 2005, during while installing inclinometers on the midsection of the Poppy Trail Landslide, it was observed that the landslide was still moving, as evidence by, there were traverse cracks that paralleled the toe of the landslide throughout the midsection of the landslide. Diagonal tension/shear cracks were observed along the north lateral scarp and across the northern section of George FF Canyon Trail where the trail crosses the lateral scarp of the landslide. Also, there is evidence that surface water has ran off the top of the landslide head scarp onto the landside mass. This water needs to be prevented from flowing onto the landslide where it can enter the new tension cracks, which can accelerate the movement of the landslide. ., �. a ,. . . . ..._ r. .. �� ;;' e www.Grour Delta come e GROUI' DELTA tolanitiaEi L-599 DI Group Delta Consultants.

PRE -CONSTRUCTION AND WINTERIZATION RECOMMENDATIONS Recognizing the emergency aspect of pre -construction of the proposed roadways and winterization of the Poppy Trail Landslide, it is recommended that several steps be taken during the construction of the ATV and the temporary access roads. 1. A small bulldozer should be used to seal the renewed tension cracks that developed to prevent water infiltration. At this time, the cracks are small but with time they could grow larger. This can be achieved by pushing soil into the cracks and track rolling the soil to a tight compaction. The toe of the landslide should be compacted with a bulldozer to seal any fractures and loose soil materials. 2. The guesthouse and landslide head scarp pose an emanate danger to persons traveling on the ATV and temporary access road. Therefore the guesthouse should be demolished. The demolition debris should not be stockpiled above the head scarp but taken offsite. After the guesthouse is removed, the landslide head scarp should be flattened to 1 horizontal to 1 to reduce rock and debris fall hazards from the scarp. A temporary fence should be placed on the uphill side of the ATV road to catch any debris that may fall from above the head scarp. The fence may not be suitable for retaining large boulders or debris. 3. Before the rainy season, UV resistant plastic sheeting should be placed over the head scarp to the ATV road and from the ATV road over the toe of the landslide to prevent water from entering the landslide mass and to prevent erosion. After the abandonment of the ATV road, the landslide should eventually be completely covered with the plastic extending over the edges of the landside and from the laidback head scarp to the toe. Drainage off the plastic sheeting should be diverted away from the landslide to prevent water from accumulating on the landslide mass and to protect the temporary access road below Poppy Trail. 4. Temporary measures should be installed to divert any water collected on the paved slope ditches and drainage areas above the head scarp.

(GDC) is pleased to present this letter to provide emergency recommendations related to the Poppy Trail Landslide. of March 11, 2005. Our understanding of the project and recommendations are outlined below. We have not as yet performed any detailed geologic mapping, subsurface exploration, laboratory analyses or engineering calculations. Rather, our role has only been to advise the City on an emergency basis to aid in evaluating the overall safety of the subject slide and the affected residences. As such, this letter is based only on our observations, preliminary geologic reconnaissance, professional judgment, and a cursory review of published geologic reports and City records regarding the history of the subject slope. 1.0 SITE SUMMARY On March 11, 2005, GDC was contacted by Mr. Roger Vink of the Rolling Hills Homeowners Association to perform a site reconnaissance of a landslide that occurred the day before and advice the City regarding its condition. During the site reconnaissance on March 12, 2005, it was noted that a significant landslide had occurred that completely blocked Poppy Trail near Portuguese Bend Road, below #1 Poppy Trail guesthouse. The landslide overall measured about 300 feet long, 150 wide, with a head scarp of about 30 feet vertical below the lower graded pad of the guesthouse. Poppy Trail has been over -ridden by slide debris. To provide access to homeowners on Poppy Trail, the Home Owners Association was using a horse trail located down slope from the current road. f a GROUT' ri9:i::tl ti r:A:tF1 L-599 Group Dclta Consult;ints. Inc. Poppy Trail Land,fidc City of Rolling Hills The slide mass has numerous fractures, mostly in the central portion, that were observed to extend depths estimated to be up to 20 feet deep. The slide has also displaced and removed a paved drainage swale near mid -slope. The head scarp falls Angeles County officials. within the guesthouse foundation, which has been exposed and red tagged by Los Many irrigation lines and concrete paved portion of the landslide. Irrigation lines, a guesthouse footing and wall debris were foundation head scarp. slope drains were noted in the central collector pipe for roof runoff next to the noticed in the area of the guesthouse Since the original site visit, local residents have constructed an access road below Poppy Trail which was covered with Crushed Miscellaneous Base (CMB). This new access road was used to drive the blocked residence automobiles into a safe area on the other side of the landside and to attempt to improve the road for All Terrain Vehicle (All) use. Lights have been stung along the trail with extension cords and florescent light bulbs. A water hose was found along the trail with water pressure. The hose was used for dust control and for the residences to attempt to achieve proper compaction of the sand and gravel. 2.0 SHORT-TERM RECOMMENDATIONS Currently, GDC is in the process of performing detailed mapping and drilling of the landslide. However, at your request and recognizing the emergency aspect of the situation, it is recommended that several steps be taken. 1. A small bulldozer should be used to seal the surface of the landslide mass where tension cracks have developed to prevent water infiltration and to remove the risk of someone slipping and/or falling. This can be achieved by pushing soil into the cracks and track rolling the soil to a tight compaction. 2. During the bulldozer grading the resulting surface should be sloped for drainage. Any large trees and brush on the slide should be cut and removed. The City should consider putting temporary fencing behind the head scarp and a catchment fence along the toe of the landslide. 3. With time and weather permitting, UV resistant plastic sheeting should be placed over the head scarp and in the two graben areas as a minimal action to prevent water from entering the landslide mass and to prevent erosion. The landslide should eventually be completely covered with the plastic extending over the edges of the landside. Drainage off of the plastic sheeting should be diverted away from the landslide to prevent water from accumulating on the landslide mass and to protect the temporary access road below Poppy Trail. L-599 Group 1)clta Consultants. Inc. i Poppy Trail I_:nul'IRlc City of Rollin_ Hills 4. Temporary measures should be installed to divert any water collected on the paved slope ditches. Sand bags, a makeshift catch basin made of sand bags in a shallow pit and a corrugated metal or PVC pipe or an "industrial sock drain" could be used for this purpose. The drainage devices should convey collected water down the slope away from the landside mass. Care should be taken to convey the water beyond the current access road and not to allow the water to enter the toe of the landslide. 5. A more complete inspection should be made of the areas above the landslide around the guesthouse and tennis court areas. Measures should be taken to prevent any runoff from the properties above from draining onto the landslide. This includes runoff from the roofs, into drain inlets and into paved or unpaved ditches since the outlets are unknown at this time. This may include use of sandbags, installation of temporary pipes, plastic sheeting, temporary re -grading, (which could require removal of driveways) and even redirecting the roof gutter down spouts into pipe systems and diverted away from the landslide mass. 6. NOTE: The top of the slide is a near vertical slope about 30 feet high. This scarp is highly unstable and care should taken during any bulldozer work, plastic sheeting or sandbagging to not further de -stabilize the scarp. or endanger personnel by working too close to the top or bottom of the scarp. As part of the first phase of this emergency, GDC will drill 2 to 3 bucket auger holes. Since the landside might not be accessible, the borings will be drilled below the landslide to determine the stability of the temporary access road and on Poppy Trail. This data will help determine the soil and rock quality and if the site is on a larger landslide. Aerial photos will be analyzed as .part of this first phase. Cross -sections would be drawn based on the mapping, down -hole logging and observed landslide geometry. This data will be used to select locations and depths for borings.

We enclose updated safety mitigation recommendations from our consulting geologist that are necessary to be implemented on your property to help protect against aggravation of the existing landslide as we approach the rainy season. These mitigation measures are outlined in the attached letter dated September 1, 2005. Pursuant to Rolling Hills Municipal Code Section 8.24.020 ("Duty of Owner or Possessor of Property") "every person who owns or is in possession of any property, place or area within the boundaries of the City shall, at his or her own expense, maintain the property, place or area free from any nuisance." Rolling Hills Municipal Code Section 8.28.010 defines any condition on property that has or will aggravate, enlarge or accelerate an active landslide to be a public nuisance subject to abatement pursuant to Chapter 8.24. We have enclosed a copy of both Chapters 8.24 and 8.28 for your review. Pursuant to Section 8.24.030, you are hereby directed to implement the following measures in order to abate conditions on your property that will potentially aggravate and accelerate the existing landslide: 1. Seal renewed tension cracks to prevent water infiltration. 2. Demolish the guesthouse and remove all debris from the site. 3. Flatten headscarp to 1:1 slope. 4. Cover entire affected area with UV resistant plastic sheeting. 5. Install temporary drainage devices to divert stormwater from entering landslide area from locations above the head scarp of the landslide. The above measures must be implemented by September 15, 2005. You are hereby notified that if you do not implement .the nuisance abatement actions by September 15, 2005, a nuisance abatement hearing will be conducted before the City Council at its regular meeting on Monday, September 26, 2005 beginning at 7:30 p.m. in the Rolling Hills City Council Chambers, 2 Portuguese Bend Road.

(GDC) is pleased to present this letter to provide pre -construction and winterization for construction recommendations related to the .construction of the ATV road across the Poppy Trail Landslide and the lower access road. Currently, GDC is in the process of installing inclinometers in the landslide and observed the following: On September 1, 2005, during while installing inclinometers on the midsection of the Poppy Trail Landslide, it was observed that the landslide was still moving, as evidence by, there were traverse cracks that paralleled the toe of the landslide throughout the midsection of the landslide. Diagonal tension/shear cracks were observed along the north lateral scarp and across the northern section of George FF Canyon Trail where the trail crosses the lateral scarp of the landslide. Also, there is evidence that surface water has ran off the top of the landslide head scarp onto the landside mass. This water needs to be prevented from flowing onto the landslide where it can enter the new tension cracks, which can accelerate the movement of the landslide. •`' • www.Grou Delta com s GROUP DELTA ttuaYi1fL1 1 L-599 DI Poppy Trail Landslide Group Delta Consultants. Inc. 2 City of Rolling Hills PRE -CONSTRUCTION AND WINTERIZATION RECOMMENDATIONS Recognizing the emergency aspect of pre -construction of the proposed roadways and winterization of the Poppy Trail Landslide, it is recommended that several steps be taken during the construction of the ATV and the temporary access roads. 1. A small bulldozer should be used to seal the renewed tension cracks that developed to prevent water infiltration. At this time, the cracks are small but with time they could grow larger. This can be achieved by pushing soil into the cracks and track rolling the soil to a tight compaction. The toe of the landslide should be compacted with a bulldozer to seal any fractures and loose soil materials. 2. The guesthouse and landslide head scarp pose an emanate danger to persons traveling on the ATV and temporary access road. Therefore the guesthouse should be demolished. The demolition debris should not be stockpiled above the head scarp but taken offsite. After the guesthouse is removed, the landslide head scarp should be flattened to 1 horizontal to 1 to reduce rock and debris fall hazards from the scarp. A temporary fence should be placed on the uphill side of the AN road to catch any debris that may fall from above the head scarp. The fence may not be suitable for retaining large boulders or debris. 3. Before the rainy season, UV resistant plastic sheeting should be placed over the head scarp to the ATV road and from the ATV road over the toe of the landslide to prevent water from entering the landslide mass and to prevent erosion. After the abandonment of the AN road, the landslide should eventually be completely covered with the plastic extending over the edges of the landside and from the laidback head scarp to the toe. Drainage off the plastic sheeting should be diverted away from the landslide to prevent water from accumulating on the landslide mass and to protect the temporary access road below Poppy Trail. 4. Temporary measures should be installed to divert any water collected on the paved slope ditches and drainage areas above the head scarp. Sand bags, a makeshift catch basin made of sand bags in a shallow pit and a corrugated metal or PVC pipe or an "industrial sock drain" could be used for this purpose. The drainage devices should convey collected water down the slope away from the landside mass. Care should be taken to convey the water beyond the current access road and not to allow the water to enter the toe of the landslide. 5. A more complete inspection should be made of the areas above the landslide around the guesthouse and tennis court areas. Measures should L-599 DI Group Delta Consultants. Inc. Poppy Trail Landslide 3 City of Rolling Hills be taken to prevent any runoff from the properties above from draining onto the landslide. This includes runoff from the roofs, into drain inlets and into paved or unpaved ditches since the outlets are unknown at this time. This may include use of sandbags, installation of temporary pipes, plastic sheeting, temporary re -grading, (which could require removal of driveways) and even redirecting the roof gutter down spouts into pipe systems and diverted away from the landslide mass. As part of the pre -construction phase of this grading, GDC is installing 3 inclinometers to monitor landslide movement during grading. This data will help determine the stability of the landslide. Closure This letter summarizes the opinion of GDC, based on the limited walkover, exploration and geological mapping of the landslide, observation of the landside conditions and the limited review of the subject references.

We have not as yet performed any detailed geologic mapping, subsurface exploration, laboratory analyses or engineering calculations. Rather, our role has only been to advise the City on an emergency basis to aid in evaluating the overall safety of the subject slide and the affected residences. As such, this letter is based only on our observations, preliminary geologic reconnaissance, professional judgment, and a cursory review of published geologic reports and City records regarding the history of the subject slope. 1.0 SITE SUMMARY On March 11, 2005, GDC was contacted by Mr. Roger Vink of the Rolling Hills Homeowners Association to perform a site reconnaissance of a landslide that occurred the day before and advice the City regarding its condition. During the site reconnaissance on March 12, 2005, it was noted that a significant landslide had occurred that completely blocked Poppy Trail near Portuguese Bend Road, below #1 Poppy Trail guesthouse. The landslide overall measured about 300 feet long, 150 wide, with a head scarp of about 30 feet vertical below thelower graded pad of the guesthouse. Poppy Trail has been over -ridden by slide debris. To provide access to homeowners on Poppy Trail, the Home Owners Association was using a horse trail located down slope from the current road. GROUT' R.k'J 4 4 Cili p L_j09 Group Drlta Consultants. Inc. Poppy y Trail Land liilc City of Rolling ;laic The slide mass has numerous fractures, mostly in the central portion, that were observed to extend depths estimated to be up to 20 feet deep. The slide has also displaced and removed a paved drainage swale near mid -slope. The head scarp falls within the guesthouse foundation, which has been exposed and red tagged by Los Angeles County officials. Many irrigation lines and concrete paved slope drains were noted in the central portion of the landslide. Irrigation lines, a collector pipe for roof runoff next to the guesthouse footing and wall debris were noticed in the area of the guesthouse foundation head scarp. Since the original site visit, local residents have constructed an access road below Poppy Trail which was covered with Crushed Miscellaneous Base (CMB). This new access road was used to drive the blocked residence automobiles into a safe area on the other side of the landside and to attempt to improve the road for All Terrain Vehicle (All) use. Lights have been stung along the trail with extension cords and florescent light bulbs. A water hose was found along the trail with water pressure. The hose was used for dust control and for the residences to attempt to achieve proper compaction of the sand and gravel 2.0 SHORT-TERM RECOMMENDATIONS Currently, GDC is in the process of performing detailed mapping and drilling landslide. However, at your request and recognizing the emergency aspect of the situation, it is recommended that several steps be taken. 1. A small bulldozer should be used to seal the surface of the landslide mass where tension cracks have developed to prevent water infiltration and to remove the risk of someone slipping and/or falling. This can be achieved by pushing soil into the cracks and track rolling the soil to a tight compaction. 2. During the bulldozer grading the resulting surface should be slop for drainage. Any large trees and brush on the slide should be cut dand removed. The City should consider putting temporary fencing behind the head scarp and a catchment fence along the toe of the landslide. 3. With time and weather permitting, UV resistant plastic sheeting should be placed over the head scarp and in the two graben areas as a minimal action to prevent water from entering the landslide mass and to prevent erosion. The landslide should eventually be completely covered with the plastic extending over the edges of the landside. Drainage off of the plastic sheeting should be diverted away from the landslide to prevent water from accumulating on the landslide mass and to protect the temporary access road below Poppy Trail. L-599 Group Delta Con>ultants. Inc. Poppy Trail 1_anJ>hcic City orltcollin° Hills 4. Temporary measures should be installed to divert any water collected on the paved slope ditches. Sand bags, a makeshift catch basin made of sand bags in a shallow pit and a corrugated metal or PVC pipe or an "industrial sock drain" could be used for this purpose: The drainage devices should convey collected water down the slope away from the landside mass. Care should be taken to convey the water beyond the current access road and not to allow the water to enter the toe of the landslide. 5. A more complete inspection should be made of the areas above the landslide around the guesthouse and tennis court areas. Measures should be taken to prevent any runoff from the properties above from draining onto the landslide. This includes runoff from the roofs, into drain inlets and into paved or unpaved ditches since the outlets are unknown at this time. This may include use of sandbags, installation of temporary pipes, plastic sheeting, temporary re -grading, (which could require removal of driveways) and even redirecting the roof gutter down spouts into pipe systems and diverted away from the landslide mass. 6. NOTE: The top of the slide is a near vertical slope about 30 feet high. This scarp is highly unstable and care should taken during any bulldozer work. plastic sheeting or sandbagging to not further de -stabilize the scarp. or endanger personnel by working too close to the top or bottom of the scarp. As part of the first phase of this emergency, GDC will drill 2 to 3 bucket auger holes. Since the landside might not be accessible, the borings will be drilled below the landslide to determine the stability of the temporary access road and on Poppy Trail. This data will help determine the soil and rock quality and if the site is on a larger landslide. Aerial photos will be analyzed as part of this first phase. Cross -sections would be drawn based on the mapping, down -hole logging and observed landslide geometry. This data will be used to select locations and depths for borings. a (2,1:0L;1) L-599 Group Delta Consultants. Inc.

BE A PUBLIC NUISANCE AND ORDERING THE ABATEMENT THEREOF. THE CITY COUNCIL OF THE CITY OF ROLLING HILLS. DOES HEREBY FIND DECLARE AND ORDER AS FOLLOWS: Section 1. Pursuant to Section 8.24.030 of the Rolling Hills Municipal Code, the City Manager notified Mr. Alan Sheen, owner of that certain real property in the City of Rolling Hills commonly known as 1 Poppy Trail (Lot 90-B-RH);to abate conditions on his property that would potentially aggravate and accelerate an existing landslide. The measures include sealing renewedtension cracks to prevent water infiltration; demolishing the guesthouse and removing all debris from the site, flattening the headscarp to a 1:1 slope, covering the entire affected area with UV resistant plastic sheeting, and installing temporary drainage devices to divert stormwater from entering the landslide area from locations above the headscarp of the landslide. The notice directed that, the measures be taken within 15 days of the date of the notice; otherwise the City Council would hold a public hearing on September 26, 2005 in the City Council Chambers of City Hall to hear any protests' the owner might have to the abatement of the. nuisance. On September 2, 2005 the City posted a notice of substandard property at the; site apprising the property owners of the unsafe and unsightlyconditions that. exist on the property. Section 2. No action to abate the nuisance has been taken by the property, owner. Consequently, on September 26, 2005, the City Council held a public hearing to allow the City Manager, the property owner and any other interested parties to testify and submit evidence - regarding the condition of the property located at 1 Poppy Trail. The property owner did not . . attend. the public hearing. The property owner's attorney, Craig Collins was present and participated in the hearing. Section 3. . Based upon staff reports, related documents and the evidence presented at the time of the hearing, the City Councilmakes the following findings of fact a. The property located at 1 Poppy Trail is located in an .active landslide in the City of Rolling: Hills.' The property is improved with a single family residence, swimming pool, water feature, stable, tennis court and illegal nonconforming. guesthouse. Inspections of the property demonstrate that the single family residence and guesthouse are presently uninhabited. b. Following the activation of the landslide in early 2005, a geologist engaged by the City, with the property owner's permission, conducted borings and other tests on the property to. better .understand the structure of the landslide inorder to enable all interested parties to evaluate their options. A copy of the geologist's report was provided to the owner of 1 Poppytrail. c. , Currently, the foundation of the guesthouse is exposed from below and rests at the top of the active landslide. The guesthouse's concrete foundation was damaged in the landslide, and it continues to suffer damage as the ground moves. The guesthouse was red -tagged as unsafe to occupy by the County of Los Angeles on March 7, 2005 and in its current condition, it cannot be used; further it is unsightly and causes visual blight. Due to its location in a landslide, its condition will only worsen, and with additional rain will likely fall into the canyon. Hence,. the guesthouse represents a danger to residents, adjoining properties, public utilities, roads and trails. d. The driveway on the property has major cracks and portions are directly involved inthe landslide. Irrigation and drainage pipes are open and exposed and non-functional. The exposed' drainage devices, exposed headscarp _ofthe landslide and unmodified headscarp will permit the intrusion of water into the landslide,` that will continue to adversely impact the stability of 1 Poppytrail as well as that of surrounding properties, roads and "trails. e. All of theforegoing together -or -separately, as further described in the attached correspondence (Exhibit A) represent a public nuisance and a threat to public safety., Section 5. On the basis of the foregoing, and of the evidence contained in the record, the City Council finds and determines that the landslidecondition of the property at 1 Resolution No. 996. Poppytrail, the condition of the guesthouse, the open crevices and fissures, and the exposed irrigation and drainage pipes and facilities separately and collectively constitute a public nuisance within the meaning of Sections 8.24.010 and 8.28.010 of the Municipal Code, and constitute a condition that is injurious to the public health, safety and welfare. The City Council further finds that by allowing the above described conditions to remain unabated through the 2005-2006 winter rainy season, stormwater will further infiltrate the landslide and will further destabilize the property and the guesthouse, creating a danger to persons and property in the area. Section 6. In accordance with the foregoing, and because it is the duty of property owners to maintain their properties free of nuisances, the City Council orders that the property owner prepare and submit a written plan to the City within ten (10) days of the adoption of this Resolution providing for implementation of the corrective winterization measures described in Section 1 of this Resolution and further described in the attached correspondence (Exhibit A); further, that the property owner commence implementation of the plan and performance of the corrective measures on or before October 10, 2005; and, that the corrective measures be completed by the property owner on or before November 10, 2005. In the event that the property owner fails to submit a plan and/or fails to commence performance of the corrective measures by the above -described deadlines, than the City may, on or after October 26, 2005 perform the corrective measures at the property owner's expense as authorized in Section 8.24.060 of the Municipal Code. Section 7. In the nuisance is not abated as specified herein, then the City Manager is directed to cause the nuisance to be abated by the City, and also is directed to notify the property owner in writing by certified mail and regular mail of the cost of removal of the nuisance and that payment in full for removal of the nuisance is due to the City within 10 days of the date of mailing of the notice. If the total cost of abating the nuisance is not paid to the City within 10 days after the date of the notice, the City Clerk shall record, in the. Office of the County Recorder, a statement of the total balance due to the City, which shall constitute a lien upon the property. Section 8. The City Clerk is hereby directed to send a copy of this resolution by certified and regular mail to the owner of the property located at 1 Poppy Trail. Section 9. This resolution shall take effect immediately on September 26, 2005. PASSED, APPROVED AND ADOPTED THIS 26t DAY OF SEPTA ER, 2005 Godfrey Pe e Mayor ATTEST: Craig R.

Diagonal tension/shear cracks were observed along the north lateral scarp and across the northern section of George FF Canyon Trail where the trail crosses the lateral scarp of the landslide. Also, there is evidence that surface water has ran off the top of the landslide head scarp onto the landside mass. This water needs to be prevented from flowing onto the landslide where it can enter the new tension cracks, which can accelerate the movement of the landslide. ♦ _ •www•.GrotinDelta.corrt• ii: ,♦ . ,. i<.• . Resolution No. 996 GROUP J DELTA L-599 DI Group Delta Consultants. Inc. PRE -CONSTRUCTION AND WINTERIZATION RECOMMENDATIONS Poppy Trail Landslide City of Rolling Hills Recognizing the emergency aspect of pre -construction of the proposed roadways and winterization of the Poppy Trail Landslide, it is recommended that several steps be taken during the construction of the ATV and the temporary access roads. 1. A small bulldozer should be used to seal the renewed tension cracks that developed to prevent water infiltration. At this time, the cracks are small but with time they could grow larger. This can be achieved by pushing soil into the cracks and track rolling the soil to a tight compaction. The toe of the landslide should be compacted with a bulldozer to seal any fractures and loose soil materials. 2. The guesthouse and landslide head scarp pose an emanate danger to persons traveling on the ATV and temporary access road. Therefore the guesthouse should be demolished. The demolition debris should not be stockpiled above the head scarp but taken offsite. After the guesthouse is removed, the landslide head scarp should be flattened to 1 horizontal to 1 to reduce rock and debris fall hazards from the scarp. A temporary fence should be placed on the uphill side of the ATV road to catch any debris that may fall from above the head scarp. The fence may not be suitable for retaining large boulders or debris. 3. Before the rainy season, UV resistant plastic sheeting should be placed over the head scarp to the ATV road and from the ATV road over the toe of the landslide to prevent water from entering the landslide mass and to prevent erosion. After the abandonment of the ATV road, the landslide should eventually be completely covered with the plastic extending over the edges of the landside and from the laidback head scarp to the toe. Drainage off the plastic sheeting should be diverted away from the landslide to prevent water from accumulating on the landslide mass and to protect the temporary access road below Poppy Trail. 4. Temporary measures should be installed to divert any water collected on the paved slope ditches and drainage areas above the head scarp. Sand bags, a makeshift catch basin made of sand bags in a shallow pit and a corrugated metal or PVC pipe or an "industrial sock drain" could be used for this purpose. The drainage devices should convey collected water down the slope away from the landside mass. Care should be taken to convey the water beyond the current access road and not to allow the water to enter the toe of the landslide. 5. A more complete inspection should be made of the areas above the landslide around the guesthouse and tennis court areas. Measures should Resolution No. 996 -7- L-599 DI Poppy Trail Landslide Group Delta Consultants. Inc. 3 City of Rolling Hills be taken to prevent any runoff from the properties above from draining onto the landslide. This includes runoff from the roofs, into drain inlets and into paved or unpaved ditches since the outlets are unknown at this time. This may include use of sandbags, installation of temporary pipes, plastic sheeting, temporary re -grading, (which could require removal of driveways) and even redirecting the roof gutter down spouts into pipe systems and diverted away from the landslide mass. As part of the pre -construction phase of this grading, GDC is installing 3 inclinometers to monitor landslide movement during grading. This data will help determine the stability of the landslide. Closure This letter summarizes the opinion of GDC, based on the limited walkover, exploration and geological mapping of the landslide, observation of the landside conditions and the limited review of the subject references. This evaluation was performed in accordance with generally accepted local standards using that degree of care and skill ordinarily exercised under similar circumstances by reputable geotechnical consultants practicing in this or similar localities. No other warranty, expressed or implied, is made as to the professional advice included in this report. The conclusions for this project are, to a high degree dependent upon proper quality control from the contractor. Consequently, the recommendations are made contingent on the opportunity of GDC to observe the contractors operations including slurry, grouting or any excavating. If parties other than GDC are engaged to provide such services, they must be notified that they will be required to assume complete responsibility for the geotechnical phase of the project by concurring with the conclusions in this report or provide alternate recommendations as deemed appropriate.

(GDC) is pleased to present this letter to provide emergency recommendations related to the Poppy Trail Landslide of March 11, 2005. Our understanding of the project and recommendations are outlined below. We have not as yet performed any detailed geologic mapping, subsurface exploration, laboratory analyses or engineering calculations. Rather, our role has only been to advise the City on an emergency basis to aid in evaluating the overall safety of the subject slide and the affected residences. As such, this letter is based only on our observations, preliminary geologic reconnaissance, professional judgment, and a cursory review of published geologic reports and City records regarding the history of the subject slope. 1.0 SITE SUMMARY On March 11, 2005, GDC was contacted by Mr. Roger Vink of the Rolling Hills Homeowners Association to perform a site reconnaissance of a landslide that occurred the day before and advice the City regarding its condition. During the site reconnaissance on March 12, 2005, it was noted that a significant landslide had occurred that completely blocked Poppy Trail near Portuguese Bend Road, below #1 Poppy Trail guesthouse. The landslide overall measured about 300 feet long, 150 wide, with a head scarp of about 30 feet vertical below the lower graded pad of the guesthouse. Poppy Trail has been over -ridden by slide debris. To provide access to homeowners on Poppy Trail, the Home Owners Association was using a horse trail located down slope from the current road. • uv.w.C,ronhl)clr:r.com Resolution No. 996 -11- L-599 Poppy Trail Landslide Group Delta Consultants. Inc. 2 City of Rolling Hills GI:OUI DELTA Iitra--n i The slide mass has numerous fractures, mostly in the central portion, that were observed to extend depths estimated to be up to 20 feet deep. The slide has also displaced and removed a paved drainage swale near mid -slope. The head scarp falls within the guesthouse foundation, which has been exposed and red tagged by Los Angeles County officials. Many irrigation lines and concrete paved slope drains were noted in the central portion of the landslide. Irrigation lines, a collector pipe for roof runoff next to the guesthouse footing and wall debris were noticed in the area of the guesthouse foundation head scarp. Since the original site visit, local residents have constructed an access road below Poppy Trail which was covered with Crushed Miscellaneous Base (CMB). This new access road was used to drive the blocked residence automobiles into a safe area on the other side of the landside and to attempt to improve the road for All Terrain Vehicle (ATV) use. Lights have been stung along the trail with extension cords and florescent light bulbs. A water hose was found along the trail with water pressure. The hose was used for dust control and for the residences to attempt to achieve proper compaction of the sand and gravel. 2.0 SHORT-TERM RECOMMENDATIONS Currently, CDC is in the process of performing detailed mapping and drilling of the landslide. However, at your request and recognizing the emergency aspect of the situation, it is recommended that several steps be taken. 1. A small bulldozer should be used to seal the surface of the landslide mass where tension cracks have developed to prevent water infiltration and to remove the risk of someone slipping and/or falling. This can be achieved by pushing soil into the cracks and track rolling the soil to.a tight compaction. 2. During the bulldozer grading the resulting surface should be sloped for drainage. Any large trees and brush on the slide should be cut and removed. The City should consider putting temporary fencing behind the head scarp and a catchment fence along the toe of the landslide. 3. With time and weather permitting, UV resistant plastic sheeting should be placed over the head scarp and in the two graben areas as a minimal action to prevent water from entering the landslide mass and to prevent erosion. The landslide should eventually be completely covered with the plastic extending over the edges of the landside. Drainage off of the plastic sheeting should be diverted away from the landslide to prevent water from accumulating on the landslide mass and to protect the temporary access road below Poppy Trail. Resolution No. 996 -12- L-599 Group Delta Consultants. Inc. Poppy Trail Landslide 3 City of Rolling Hills 4. Temporary measures should be installed to divert any water collected on the paved slope ditches. Sand bags, a makeshift catch basin made of sand bags in a shallow pit and a corrugated metal or PVC pipe or an "industrial sock drain" could be used for this purpose. The drainage devices should convey collected water down the slope away from the Iandside mass. Care should be taken to convey the water beyond the current access road and not to allow the water to enter the toe of the landslide. 5. A more complete inspection should be made of the areas above the landslide around the guesthouse and tennis court areas. Measures should be taken to prevent any runoff from the properties above from draining onto the landslide. This includes runoff from the roofs, into drain inlets and into paved or unpaved ditches since the outlets are unknown at this time. This may include use of sandbags, installation of temporary pipes, plastic sheeting, temporary re -grading, (which could require removal of driveways) and even redirecting the roof gutter down spouts into pipe systems and diverted away from the landslide mass. 6. NOTE: The top of the slide is a near vertical slope about 30 feet high. This scarp is highly unstable and care should taken during any bulldozer work, plastic sheeting or sandbagging to not further de -stabilize the scarp, or endanger personnel by working too close to the top or bottom of the scarp. As part of the first phase of this emergency, GDC will drill 2 to 3 bucket auger holes. Since the Iandside might not be accessible, the borings will be drilled below the landslide to determine the stability of the temporary access road and on Poppy Trail. This data will help determine the soil and rock quality and if the site is on a larger landslide. Aerial photos will be analyzed as part of this first phase. Cross -sections would be drawn based on the mapping, down -hole logging and observed landslide geometry. This data will be used to select locations and depths for borings.

ROLLING, HILLS DOES HEREBY FIND DECLARE AND ORDER AS FOLLOWS: Section 1. Pursuant to Section 8.24.030 of the Rolling Hills Municipal Code, theCity Manager notified Mr. Alan. Sheen, owner of that certain real property in the City of Rolling Hills commonly known as 1 Poppy Trail (Lot 90-B-RH), to abate conditions on his property that would potentially aggravate and accelerate an existing landslide. The measures include sealing renewed tension cracks toprevent water infiltration, demolishing the guesthouse and removing all debris from the site, flattening the headscarp to a 1:1 slope, covering the entire affected area with UV resistant plastic sheeting, and installing temporary drainage devices to ;divert stormwater from. entering the landslide area from locations above the headscarp of the landslide The notice directed that themeasures be taken within 15 days of the date of the, notice, otherwise the City Council would hold a public hearing on September 26, 2005 in the City Council Chambers of City Hall to hear any protests the ownermight have to the abatement of the nuisance. On September 2, 2005 the City posted a notice of substandard property at the site apprising the property owners of the unsafe and unsightly conditions that exist on the property. Section 2. No action to abate the nuisance has been taken by the property owner. Consequently, on September 26, 2005, the City Council held a public hearing to allow the City Manager, the property owner and any other interested parties to testify and submit evidence regarding the condition of the property located at 1 Poppy Trail. The property owner did not attend the public hearing, The property owner's attorney, Craig Collins was present and participated inthe hearing. Section 3. Based upon staff reports, related documents and the evidence presented at the time of the hearing, the City Council makes the following findings of fact: a. The property located at 1 Poppy Trail is located in an active landslide in the City of Rolling Hills. The property .is improved with a single family residence, swimming pool, water feature, stable, tennis court and illegal nonconforming guesthouse.• Inspections of the property demonstratethat the single family residence and guesthouse are presently uninhabited. b. Following the activation of the landslide in early 2005, a geologist engaged by the City,. with the property owner's permission, conducted borings and other tests on the property to betterunderstand the structure of the landslide in order to enable all interested parties to evaluate their options. A copy of the geologist's report was provided to the owner of 1 Poppytrail. c. . Currently, the foundation of the guesthouse is exposedfrom below and rests at the top of the active landslide. The guesthouse's concrete foundationwas damaged in the landslide, and it continues to suffer damage as the ground moves. The guesthouse was red -tagged as unsafe to occupy by the County of Los Angeles on March 7,. 2005 and in its current condition, it cannot be used; further it is unsightly and causes visual blight. Due to its location in a°' landslide, its condition will only worsen, and with additional rain will likely fall into the canyon. Hence, the guesthouse represents a danger to residents,. adjoining properties, public utilities, roads and trails. d. The driveway, on the property has major cracks and portions are directly involved in the landslide. Irrigation and: drainage pipes are open and exposed and non-functional. The exposed drainage devices, exposed .headscarp of the landslide and unmodified headscarp will permit the intrusion of water into the landslide, that will continue to adversely impact the stability of 1 Poppytrail as well as that of surrounding properties, roads and trails. e.' All of the foregoing together or separately, as further described in the attached correspondence (Exhibit A) represent a public nuisance and a threat to public safety. Section 5. On the basis of the foregoing, and of the evidence contained in the record, the City Council finds and ;determines that the landslide condition of the property at 1 Resolution No. 996 Poppytrail, the condition of the guesthouse, the open crevices and fissures, and the exposed irrigation and drainage pipes and facilities separately and collectively constitute a public nuisance within the meaning of Sections 8.24.010 and 8.28.010 of the Municipal Code, and constitute a condition that is injurious to the public health, safety and welfare. The City Council further finds that by allowing the above described conditions to. remain unabated through the 2005-2006 winter rainy season, stormwater will further infiltrate the landslide and will further destabilize the property and the guesthouse, creating a danger" to persons and property in the area. Section 6. In accordance with the foregoing, and because it is the duty of property owners to maintain their properties free of nuisances, the City Council orders that the property owner prepare and submit a written plan' to the City within ten (10) days of the adoption of this Resolution providing for implementation of the corrective winterization measures described in Section 1 of this Resolution and further described in the attached correspondence (Exhibit A); further, that the property owner commence implementation of the plan and performance of the corrective measures on or before October 10, 2005; and; that the corrective measures be completed by the property owner on or before November 10, 2005. In the event that the property owner fails to submit a plan and/or fails to commence performance of the. corrective measures by the above -described deadlines, than the City may, on or after October 26, 2005 perform the corrective measures at the property owner's expense as authorized in Section 8.24.060 of the Municipal Code. Section 7. In the nuisance is not abated as specified herein, then the City Manager is directed to cause the nuisance to be abated by the City, and also is directed to notify the property owner in writing by certified mail and regular mail of the cost of removal of the nuisance and that payment in full for removal of the nuisance is due to the City within 10 days ofthe date of mailing of the notice. If the total cost of abating the nuisance is not paid to the City within 10 days after the date of the notice, the City Clerk shall record, in the Office of the County Recorder, a statement of the total balance due to the City, which shall constitute a lien upon the property. Section 8. The City Clerk is hereby directed to send a copy of this resolution by certified and regular mail to theowner of the property located at 1 Poppy Trail. Section 9. This resolution shall take effect immediately on September 26, 2005. PASSED, APPROVED AND ADOPTED THIS 26"' DAY OF SEPT ER, 2005 Godfrey Pe e Mayor ATTEST: Craig R.

In that correspondence, we requested that you implement these measures by September 15, 2005. To our knowledge, these measures have not been performed as of this date. We enclose updated safety mitigation recommendations from our consulting geologist that are necessary to be implemented on your property to help protect against aggravation of the existing landslide as we approach the rainy season. These mitigation measures are outlined in the attached letter dated September 1, 2005. Pursuant to Rolling Hills Municipal Code Section 8.24.020 ("Duty of Owner or Possessor of Property") "every person who owns or is in possession of any property, place or area within the boundaries of the City shall, at his or her own expense, maintain the property, place or area free from any nuisance." Rolling Hills Municipal Code Section 8.28.010 defines any condition on property that has or will aggravate, enlarge or accelerate an active landslide to be a public nuisance subject to abatement pursuant to Chapter 8.24. We have enclosed a copy of both Chapters 8.24 and 8.28 for your review. Pursuant to Section 8.24.030, you are hereby directed to implement the following measures in order to abate conditions on your property that will potentially aggravate and accelerate the existing landslide: 1. Seal renewed tension cracks to prevent water infiltration. 2. Demolish the guesthouse and remove all debris from the site. 3. Flatten headscarp to 1:1 slope. 4. Cover entire affected area with UV resistant plastic sheeting. 5. Install temporary drainage devices to divert stormwater from entering landslide area from locations above the head scarp of the landslide. The above measures must be implemented by September 15, 2005. You are hereby notified that if you do not implement the nuisance abatement actions by September 15, 2005, a nuisance abatement hearing will be conducted before the City Council at its regular meeting on Monday, September 26, 2005 beginning at 7:30 p.m. in the Rolling Hills City Council Chambers, 2 Portuguese Bend Road.

Currently, GDC is in the process of installing inclinometers in the landslide and observed the following: On September 1, 2005, during while installing inclinometers on the midsection of the Poppy Trail Landslide, it was observed that the landslide was still moving, as evidence by, there were traverse cracks that paralleled the toe of the landslide throughout the midsection of the landslide. Diagonal tension/shear cracks were observed along the north lateral scarp and across the northern section of George FF Canyon Trail where the trail crosses the lateral scarp of the landslide. Also, there is evidence that surface water has ran off the top of the landslide head scarp onto the landside mass. This water needs to be prevented from flowing onto the landslide where it can enter the new tension cracks, which can accelerate the movement of the landslide. • • www.GrounDctta.corrt• : 1 r •. , • •. , i c,. . Resolution No. 996 -6- GROUP DELTA taoiiivvrau L-599 DI Group Delta Consultants. Inc. Poppy Trail Landslide City of Rolling Hills PRE -CONSTRUCTION AND WINTERIZATION RECOMMENDATIONS Recognizing the emergency aspect of pre -construction of the proposed roadways and winterization of the Poppy Trail Landslide, it is recommended that several steps be taken during the construction of the ATV and the temporary access roads. 1. A small bulldozer should be used to seal the renewed tension cracks that developed to prevent water infiltration. At this time, the cracks are small but with time they could grow larger. This can be achieved by pushing soil into the cracks and track rolling the soil to a tight compaction. The toe of the landslide should be compacted with a bulldozer to seal any fractures and loose soil materials. 2. The guesthouse and landslide head scarp pose an emanate danger to persons traveling on the ATV and temporary access road. Therefore the guesthouse should be demolished. The demolition debris should. not be stockpiled above the head scarp but taken offsite. After the guesthouse is removed, the landslide head scarp should be flattened to 1 horizontal to 1 to reduce rock and debris fall hazards from the scarp. A temporary fence should be placed on the uphill side of the ATV road to catch any debris that may fall from above the head scarp. The fence may not be suitable for retaining large boulders or debris. 3. Before the rainy season, UV resistant plastic sheeting should be placed over the head scarp to the ATV road and from the ATV road over the toe of the landslide to prevent water from entering the landslide mass and to prevent erosion. After the abandonment of the ATV road, the landslide should eventually be completely covered with the plastic extending over the edges of the landside and from the laidback head scarp to the toe. Drainage off the plastic sheeting should be diverted away from the landslide to prevent water from accumulating on the landslide mass and to protect the temporary access road below Poppy Trail. 4. Temporary measures should be installed to divert any water collected on the paved slope ditches and drainage areas above the head scarp. Sand bags, a makeshift catch basin made of sand bags in a shallow pit and a corrugated metal or PVC pipe or an "industrial sock drain" could be used for this purpose. The drainage devices should convey collected water down the slope away from the landside mass. Care should be taken to convey the water beyond the current access road and not to allow the water to enter the toe of the landslide. 5. A more complete inspection should be made of the areas above the landslide around the guesthouse and tennis court areas. Measures should Resolution No. 996 -7- L-599 DI Poppy Trail Landslide Group Delta Consultants. Inc. 3 City of Rolling Hills be taken to prevent any runoff from the properties above from draining onto the landslide. This includes runoff from the roofs, into drain inlets and into paved or unpaved ditches since the outlets are unknown at this time. This may include use of sandbags, installation of temporary pipes, plastic sheeting, temporary re -grading, (which could require removal of driveways) and even redirecting the roof gutter down spouts into pipe systems and diverted away from the landslide mass. As part of the pre -construction phase of this grading, GDC is installing 3 inclinometers to monitor landslide movement during grading. This data will help determine the stability of the landslide. Closure This letter summarizes the opinion of GDC, based on the limited walkover, exploration and geological mapping of the landslide, observation of the landside conditions and the limited review of the subject references. This evaluation was performed in accordance with generally accepted local standards using that degree of care and skill ordinarily exercised under similar circumstances by reputable geotechnical consultants practicing in this or similar localities. No other warranty, expressed or implied, is made as to the professional advice included in this report. The conclusions for this project are, to a high degree dependent upon proper quality control from the contractor. Consequently, the recommendations are made contingent on theopportunityof GDC to observe the contractors operations including slurry, grouting or any excavating. If parties other than GDC are engaged to provide such services, they must be notified that they will be required to assume complete responsibility for the geotechnical phase of the project by concurring with the conclusions in this report or provide alternate recommendations as deemed appropriate.

(GDC) is pleased to present this letter to provide emergency recommendations related to the Poppy Trail Landslide of March 11, 2005. Our understanding of the project and recommendations are outlined below. We have not as yet performed any detailed geologic mapping, subsurface exploration, laboratory analyses or engineering calculations. Rather, our role has only been to advise the City on an emergency basis to aid in evaluating the overall safety of the subject slide and the affected residences. As such, this letter is based only on our observations, preliminary geologic reconnaissance, professional judgment, and a cursory review of published geologic reports and City records regarding the history of the subject slope. 1.0 SITE SUMMARY On March 11, 2005, GDC was, contacted by Mr. Roger Vink of the Rolling Hills Homeowners Association to perform a site reconnaissance of a landslide that occurred the day before and advice the City regarding its condition. During the site reconnaissance on March 12, 2005, it was noted that a significant landslide had occurred that completely blocked Poppy Trail near Portuguese Bend Road, below #1 Poppy Trail guesthouse. The landslide overall measured about 300 feet long, 150 wide, with a head scarp of about 30 feet vertical below the lower graded pad of the guesthouse. Poppy Trail has been over -ridden by slide debris. To provide access to homeowners on Poppy Trail, the Home Owners Association was using a horse trail located down slope from the current road. • w w w.Groi ni )cIIa.cam • Resolution No. 996 -11- L-599 Poppy Trail Landslide Group Delta Consultants. fnc. 2 City of Rolling Hills GROUP DELTA toRm fiaF1 The slide mass has numerous fractures, mostly in the central portion, that were. observed to extend depths estimated to be up to 20 feet deep. The slide has also displaced and removed a paved drainage swale near mid -slope. The head scarp falls within the guesthouse foundation, which has been exposed and red tagged by Los Angeles County officials. Many irrigation lines and concrete paved slope drains were noted in the central portion of the landslide. Irrigation lines, a collector pipe for roof runoff next to the guesthouse footing and wall debris were noticed in the area of the guesthouse foundation head scarp. Since the original site visit, local residents have constructed an access road below Poppy Trail which was covered with Crushed Miscellaneous Base (CMB). This new access road was used to drive the blocked residence automobiles into a safe area on the other side of the landside and to attempt to improve the road for All Terrain Vehicle (ATV) use. Lights have been stung along the trail with extension cords and florescent light bulbs. A water hose was found along the trail with water pressure. The hose was used for dust control and for the residences to attempt to achieve proper compaction of the sand and gravel. 2.0 SHORT-TERM RECOMMENDATIONS Currently, GDC is in the process of performing detailed mapping and drilling of the landslide. However, at your request and recognizing the emergency aspect of the situation, it is recommended that several steps be taken. 1. A small bulldozer should be used to seal the surface of the landslide mass where tension cracks have developed to prevent water infiltration and to remove the risk of someone slipping and/or falling. This can be achieved by pushing soil into the cracks and track rolling the soil to a tight compaction. 2. During the bulldozer grading the resulting surface should be sloped for drainage. Any large trees and brush on the slide should be cut and removed. The City should consider putting temporary fencing behind the head scarp and a catchment fence along the toe of the landslide. 3. With time and weather permitting, UV resistant plastic sheeting should be placed over the head scarp and in the two graben areas as a minimal action to prevent water from entering the landslide mass and to prevent erosion. The landslide should eventually be completely covered with the plastic extending over the edges of the landside. Drainage off of the plastic sheeting should be diverted away from the landslide to prevent water from accumulating on the landslide mass and to protect the temporary access road below Poppy Trail. Resolution No. 996 -12- L•599 DEI_T.\ Poppy Trail Landslide Group Delta Consultants. Inc. 3 City of Rolling Hills 4. Temporary measures should be installed to divert any water collected on the paved slope ditches. Sand bags, a makeshift catch basin made of sand bags in a shallow pit and a corrugated metal or PVC pipe or an "industrial sock drain" could be used for this purpose. The drainage devices should convey collected water down the slope away from the landside mass. Care should be taken to convey the water beyond the current access road and not to allow the water to enter the toe of the landslide. 5. A more complete inspection should be made of the areas above the landslide around the guesthouse and tennis court areas. Measures should be taken to prevent any runoff from the properties above from draining onto the landslide. This includes runoff from the roofs, into drain inlets and into paved or unpaved ditches since the outlets are unknown at this time. This may include use of sandbags, installation of temporary pipes, plastic sheeting, temporary re -grading, (which could require removal of driveways) and even redirecting the roof gutter down spouts into pipe systems and diverted away from the landslide mass. 6. NOTE: The top of the slide is a near vertical slope about 30 feet high. This scarp is highly unstable and care should taken during any bulldozer work, plastic sheeting or sandbagging to not further de -stabilize the scarp, or endanger personnel by working too close to the top or bottom of the scarp. As part of the first phase of this emergency, GDC will drill 2 to 3 bucket auger holes. Since the landside might not be accessible, the borings will be drilled below the landslide to determine the stability of the temporary access road and on Poppy Trail. This data will help determine the soil and rock quality and if the site is on a larger landslide. Aerial photos will be analyzed as part of this first phase. Cross -sections would be drawn based on the mapping, down -hole logging and observed landslide geometry. This data will be used to select locations and depths for borings.
