The purpose of our services was to evaluate the geotechnically related features observed at the site and to provide appropriate repair recommendations. Our scope of services included review of pertinent background data including: geotechnically-related documents and Teports previously prepared for the site; government groundwater reports and data: geologic maps; performance of a site visit to document the existing conditions; perform- ance of a manometer (floor level) survey across the interior floor; performance of a shallow exploratory boring- laboratory testing of selected, samples obtained- and: preparatioeE of this repffrt aarasenrang Qur # nd1-1nas. oncia� inns; and prejimina� raYair rarrijmmp�daTiragac �...�...... GENERAL SITE COND71TICVNS During our April 5. 2006 site visit, we observed- documented, and ohotoa-dDhed the genera[ site conditions at the subject property. The subject site generajly consists of a rectangular -shaped jot, 4 ;rich fronts on jack Nicklaus Boulevard to the northwest, and is bounded by simiiariy devel- oped residential, properties on the norm- east and soF,Ethwest, and by a golf course fairway on the northeast ffiaure 2). .�----- ' _.- 5710 Rin Road - San Diego, California 92123 • Phone (858) 576-1000 Fax (858) 576-9600 San Diego Irvine Ontario • Los Angeles • Oakland • Las Vegas • Salt Lake City • Phoenix _ 'sh 56840 Jack Nicklaus Blvd., Lot 42 April 26, 2006 La Quinta, California Project No. 105502001 The subject residence is located near the center of the lot and consists of a one-story, wood frame structure with attached garage. The residence is founded on a continuous perimeter footing with a slab -on -grade floor. Interior walls, including the garage, consist of drywall, ,and exterior walls are generally covered with stucco.' Based on our review of available background reports, reportedly the site is underlain by fill ma- terials, which i #urn are underlain by alluvium. Grading plans were not available for our review. During our site visit, we excavated a shallow boring in the front courtyard. Based on visual ob- servations, fill material was encountered to a depth of approximately 5- feet below the existing around surface in the borini3. As part of our evaluation, we noted the general drainage conditions at the subject property. REKIf gutters and downspouts were not observed on the residence. Several areas of potential ponding of water were noted in planter areas near the foundation of the residence. A few depressed ar- eas,zhallow sinal holes were noted hear the front walkway, north of the courtyard, and on both A chronological list of the referenced documents reviewed is, included as an attachment to this repot. A brief summerv:of the more pertinent proiect-related information is presented below. The subject site was graded in 1987. However, the grading plans and as -graded report(s) were notnvnilahle fpr our review, in April, 1986, Buena r-n119E inc. prepared a preliminary engineering report for the proposed deveiopment.

Indicated that observed distress was not related to deficiency of the structure, but foundation/soil related. • On June 17,, 2002, Vandorpe Chou Associates, Inc. performed site visit on May 21, 2002, to determine the cause of the slab cracks at the subject residence. The report also indicated that the garage slab had been removed, as had the floor coverings, and. a 3- by 4 -foot section of the concrete floor slab in the hallway. The report also indicated that an approximately 1 inch wide by 20 feet long slab crack was observed in the living room.

The evaluation included field ar�<i laboratory testing services. The report did not indicate the primary cause of the observed dis- tress, but suggested contributing factors, such as differential soli movement related to landscaDe irrigation. Recommendations were provided to improve drainage conditions by positive drainage and/or installation of a subsurface drainage system, installation of a mois- t -e ban ieE alGag the perimeter footings, and, closely monitored. fandscape irrigation.

No additional movement was observed between May and June floor level surveys. (Note, the June 6, 2003 report indicated 1 inch of additional differential across the slab.) • On January 30, 2004, Ryland Associates performed a geophysical survey to evaluate local soil subsidence at the subject site area. Seismic refraction lines indicated "not only surface anoma- lies but anomalies at depths on -the order of 200 feet or more." The report indicated that the deep anomalies may be related to fault contact; however it could not be clearly demonstrated. On July 2, 2004, Subsurface Surveys (SSS) at the request of the Homeowner's Association, performed a- seismic refraction survey in the median area on Jack Nicklaus Blvd. The pur- pose was to evaluate the subsurface conditions across the surface failure/street, curb and gutter displacement. SSS concluded that "a fault interpretation is entirely consistent with the local situation wherein the San Andreas Fault zone splays into the valley in many strands, and the SaniAndreas is one of the world's most active fault zones." SUMMARY OF FIELD OBSERVATIONS During our site .visit, we observed and photographed geotechnically-related- distress. features at the subject property. Observed cracks and separations in the interior floors and ceilings and exte- rior flatwork are' -depicted on Figure 2. In general, the observed distress included the following: Interior + i • Several.? hairline (i.e., less than 1/32 -inches wide) up to approximately 1/8 -inch wide drywall cracks were noted, and several hairline to approximately 1/4 -inch wide ceiling cracks/separations were observed in the hallway, living room, and kitchen ceilings. Some of the ceiling cracks extend approximately 20 feet. In addition, several approxi- mately'El /2- to 1 -inch wide cracks and separations were noted on the walls and ceiling of bedroom no. 3, and particularly in the bathroom. Some of the separations included lat- eral off -sets ranging from approximate 1/2- to 1 -inch wide. f, • Several floor tile cracks ranging from approximatlyl/16- to 1/4 -inches wide, and ex- tending approximately 15 feet. An approximately 3/16- to 1/4 -inch wide ceramic floor tile and wall separation was ob- served in the guest bathroom. The guest bathroom door is out -of -square and will not close. /`/in�o�/hooro 0 56840 Jack Nicklaus Blvd., Lot 42 La Quinta, California April 26, 2006 Project No. 105502001 Garage • Up to approximately 1 -inch wide separations were noted between the stem wall and ga- rage slab and between the driveway and garage slab. In addition, an approximately 1/2 - to 1 -inch wide crack, with a vertical differential of approximately 1 inch was also noted in the golf cart portion of the garage. • Several' drywall cracks were observed in the garage, including; an approximately 1- to 1 1/2 -inch wide crack near the upper right corner of the rear access door. Daylight could be seen through this crack, as the crack extended through both the drywall and stucco. • A few ceiling cracks up to approximately 1 1/2 -inches wide were noted above the water heater. Exterior • At the upper left corner, the rear garage access door frame has separated approximately 1/2 -inch. • Several, hairline to approximately 1/4 -inch wide diagonal stucco cracks were noted near the upper left corner of the rear garage access door. Further, the corner roof truss, near the access door, has sheared and pulled apart approximately 1/8- to 1 1/2 -inches. • An up 'to approximately 3/4 -inch wide separation and crack was observed between the stucco and roof truss, to the left of the front entry. • A hairline up to approximately. 3/16 -inch wide stucco crack was noted near the upper left comer of the golf cart garage door. • Numerous hairline up to approximately 1/2 -inch wide stucco cracks were noted near the corners of the northeast facing windows. Some of the cracks extend to the roof trusses. • Several'hairline up to approximately 1/8 -inch wide cracks were noted near the east end of the concrete masonry unit (CMU) privacy wall. • An approximately 1/4- to 1/2 -inch wide separation was noted between the southwest facing exterior garage wall and the block privacy wall. Jack Nicklaus Boulevard As part of our site reconnaissance, we observed and documented asphalt and curb and gutter distress features on Jack Nicklaus Blvd., just west of the subject property. In general, the distress consists of a depressed area with numerous sub -parallel asphalt cracks that generally J/17ff0&*QQre 56840 Jack Nicklaus Blvd., Lot 42 April 26, 2006 La Quinta, California Project No. 105502001 trend in an east -west direction. The asphalt cracks range from hairline, up to approximately 1 inch in width. In addition, up to approximately 1 1/2 -inch wide cracks, with up to ap- proximately 3 1/2 -inches of vertical displacement, and approximately 3/4 inches of lateral ofd set were',observed in the curb and gutter, west of the subject property. Based on a com- parison with earlier observations, the street, curbs and gutters in the area west of the subject property have continued to worsen. FLOOR LEVEL SURVEY As part of our study,.representatives from our office performed a floor level (manometer) survey across the interior floor slab of both the main portion of the residence and the bedroom adjacent to the garage. The results of our survey are presented on Figure 3. The relative elevation differen- tial across the main floor of the residence is approximately 2.9 inches, with differentials approaching approximately 1 vertical inch over 4 horizontal feet in bedroom no. 2 on the north- east side of the residence, and approximately 1 vertical inch over 8 horizontal feet in the master bedroom, located on the northwest portion of the residence. The relative elevation differential across the guestibedroom portion of the residence is approximately 4.4 inches, with differentials approaching approximately I vertical inch over 2 horizontal feet. As noted on Figure 3, in gen- eral the floor level survey results indicate the presence of significant tilting of the northern portion of the residence. In other areas, the results of the floor level survey indicate that the floor is generally within modern construction tolerances. SUBSURFACE EVALUATION AND LABORATORY TESTING As part of our evaluation, a shallow boring (HA -1) was excavated in the courtyard area near the front entry of the residence. The boring was excavated with a hand auger to a depth of approxi- mately 5.3 feet below the existing ground surface. The purpose of the boring was to observe the i subsurface conditions and to collect soil samples for laboratory testing. Bulk samples were col- lected at selected intervals within the boring and were transported to our laboratory for testing. The excavation was then backfilled with the excavated soil. The approximate location of the bor- ing is shown on the attached Figure 2. N��yr&*umrp. 56840 Jack Nicklaus Blvd., Lot 42 April 26, 2006 La Quinta, California Project No. 105502001 t �a Laboratory testing of samples included Atterberg limits, expansion index, and corrosivity includ- ing resistivity, pH, chloride content, and sulfate content. The laboratory tests were performed in our in-house lalioratory. The results of the laboratory tests performed are attached. The geologic units. encountered during our subsurface evaluation included fill overlying alluvial materials. Detailed descriptions of the earth units encountered are provided on the attached bor- ing log. As encountered, the fill generally consisted of brown, damp, loose to medium dense, silty fine sand and fine sandy silt, and brown, damp to moist, stiff to very stiff, silty clay to r clayey silt. Alluvium, encountered underlying the fill, 'generally consisted of light brown, damp, medium dense, silty fine sand. GEOLOGIC CONDITIONS The subject site; situated near the western margin of the northwest -southeast trending Coachella Valley, is bounded by the Santa Rosa/San Jacinto Mountains on the southwest and the Little San Bernardino Mountains on the northeast. The Coachella Valley is underlain by over 8,000 feet of interlayered sand, silt, clay, and gravel sediments. These sediments, derived from the adjacent mountains, ancient lake deposits, and wind blown material, are generally loosely consolidated. As part of our study, we reviewed background documents regarding faulting and land subsidence I in the vicinity of the subject site. Based on our findings, the site is not underlain by any known active faults. The closest known active fault is the San Andreas Fault, a right lateral strike -slip fault, located approximately 7 miles east of the site. Our review of groundwater reports and data indicate that groundwater levels in the La Quinta area have declined over 30 feet in the last 28 years (MWK Inc., 2005), and as of April, 2005, are at their lowest recorded levels. Studies have shown that groundwater withdrawal can lead to land subsidence and 'ground cracks (fissures). In 1948, an earth fissure was reported near Lake Ca- huilla, southwest of the site. It is believed that this feature may have been the result of heavy groundwater pumping that occurred in the area between the 1920's and late 1940's. 7 W C ., 56840 Jack Nicklaus Blvd., Lot 42 April 26, 2006 La Quinta, California Project No. 105502001 As discussed, geophysical studies were performed in the median area of Jack Nicklaus Blvd., across the zone of subsidence in January, 2004, by Ryland Associates, and in July, 2004, by Sub- surface Surveys Inc. The Ryland Associates report indicated that the subsidence/anomaly zone may be due to a fault,, and that there were indications that the anomaly extended to depths on the order of 200 feet or more. The report by Subsurface Surveys also concluded that the subject subsidence zone was likely due to a fault. In September, 2005, representatives from Ninyo & Moore partici- pated in the excavation and logging of an exploratory trench across the subject zone of deformation in the median area.. The trench was logged by geologists from our office. The result of detailed logging indicated'that the soil bedding within the alluvium was off -set along a fracture feature, and that the fracture extended up into a portion of the overlying fill materials. In addition, the magni- tude of the bedding off -set was similar to the magnitude of off -set observed in the cracks in the street and curb and gutter. Based on the results of the exploratory trench, the zone of deforma- tion/subsidence observed in the street area, is due to the formation of a recent ground fissure. FINDINGS AND CONCLUSIONS As discussed,'the purpose of our services was to evaluate the probable cause(s) of the reported geotechnically related features observed at the site and to provide appropriate repair recommen- dations. To accomplish this, we have reviewed project -related background materials, performed a geotechnical site, reconnaissance, performed a subsurface exploration and associated laboratory testing, and performed a geotechnical analysis of the data collected. In general, the distress to the interior of the residence generally included; several hairline up to approximately 1- inch wide ceiling and wall cracks/separations, with some lateral off -sets ranging from approximate 1/2- to 1 -inch wide, several floor tile cracks ranging from approximately 1/16- 1. to 1/4 -inches wide, and an approximately 3/16- to 1/4 -inch wide ceramic floor tile and wall sepa- ration in the bathroom, adjacent to bedroom no. 3. In addition, the bathroom door is out -of - square and will riot close. The observed distress to the garage generally included, several drywall cracks in the ceiling and walls up to approximately 1- to 1 1/2 -inch wide, up to approximately 1 - inch wide separations between the stem wall and garage slab and between the driveway and ga- 8 56840 Jack Nicklaus Blvd., Lot 42 La Quinta, California April 26, 2006 Project No. 105502001 rage slab, and an approximately 1/2- to 1 -inch wide garage slab crack, with a vertical differential of approximately 1 inch. The distress to the exterior and flatwork generally included, up to ap- proximately 1/8 to 1 1/2 -inch wide separations between the stucco and roof trusses/wood framing, several hairline to approximately 1/2 -inch wide stucco cracks, and several hairline up to approximately 1/8 -inch wide cracks in the CMU privacy wall. The distress observed to the exte- rior flatwork generally included several 1/16- to 1-1/2 inch wide cracks/separations, with up to approximately 3/4 of an inch vertical displacement (Figure 2). The results of our floor level survey indicated a relative elevation differential across the main floor of the residence "of approximately 2.9 inches, with a vertical differential of approximately 1 inch over 4 horizontal feet in bedroom no. 2, and approximately 1 vertical inch over 8 horizontal feet in the master bedroom. The relative elevation differential across bedroom no. 3 was approximately I , 4.4 inches, with differentials approaching approximately 1 vertical inch over 2 horizontal feet (Fig- ure 3). In general, the floor level survey results indicate significant tilting of the northern portion of the residence, which, are not within modern construction tolerances. Based on findings, it is our preliminary opinion that the observed distress to the subject residence is due to the development of a ground fissure and resultant ground subsidence, across the north- ern portion of the property, as a result of regional groundwater withdrawal. Our opinion is based on background information, the location and nature of the observed distress, the results of our floor level survey, which indicates significant tilting toward the north, and on our findings (allu- vium and fill off -sets) with regard to the exploratory trench, excavated in the median area of Jack Nicklaus Blvd. Furthermore, based on the on-going distress to Jack Nicklaus Blvd, as well as the subject property' it is also our opinion that ground subsidence as a result of groundwater with- drawal, may continue. RECOMNM"ATIONS i F We recommend chat the portions of the subject residence that have been adversely affected by the regional subsidence be repaired. As depicted on Figure 3 (Floor Level Survey), the portions of the residence that exhibit floor elevation differentials beyond construction tolerances, including 9 11 #Vh7 v& Nome 56840 Jack Nicklaus Blvd., Lot 42 April 26, 2006 La Quinta, California Project No. 105502001 the bedroom and bathroom areas north of the entry, and the bedroom and bathroom areas adja- cent to the garage, may be repaired by a releveling technique. In addition, releveling may also be extended into the garage area, which was previously replaced. Releveling of the foundation can be accomplished by a combination of mechanical jacking and mud jacking, performed by a spe- cialty contractor. After foundation releveling is complete, for cracks less than approximately 1/4 -inches wide, the cracks may be filled, via injection, with an epoxy grout. For cracks approximately 1/4 -inch or wider, we recommend that a section of the slab 2 feet wide on both sides of the crack be sawcut and removed.,The removed portion of the slab should be replaced with a new slab 5 inches thick. The slab should be reinforced with No. 4 steel reinforcing bars placed at 12 inches on center, both ways. The reinforcement should be located in the middle one-third of the slab height. We recommend that "chairs" be utilized to aid in the placement of the reinforcement. The slab should be underlain by 2 inches of moist sand, a 10 -mil visqueen vapor retarder, and 4 inches of clean sand or crushed rock. The slab should be dowelled approximately 12 inches into the exist- ing slab at an angle of about 45 degrees. We also recommend that Type V cement and a water - cement ratio of 0.45 be used, and that the concrete be placed with a slump of 4 inches. A general- ized detail of.the partial replacement of the floor slab is attached on Figure 4. Cosmetic repairs, such as drywall and stucco repairs, repairs to the CMU privacy wall, painting, etc., may be per- formed upon the completion of foundation releveling. We recommend; that the exterior flatwork and/or the flatwork that is removed as a result of the I foundation repair, be replaced with new concrete slabs. The new concrete slabs should be 6 inches 1 thick and should., be reinforced with No. 4 steel reinforcing bars placed at 18 inches on center, both ways. The reinforcement should be located in the middle one-third of the slab height. We recom- mend that "chairs" be utilized to aid in the placement of the reinforcement. We recommend that the concrete utilized in the new slabs be placed with a slump of 4 inches. Further, adequate expansion joints, not exceeding a 6 -foot spacing, should be constructed in the exterior flatwork. 10 Af�J7gV& boa« 6 56840 Jack Nicklaus Blvd., Lot 42 La Quinta, California April 26, 2006 Project No. 105502001 As previously sfated, the main cause of the slab differential and distress observed in the subject residence is due to regional ground subsidence primarily caused by dewatering. It is our opinion that the subsidence will likely continue to some extent. The timing of the regional subsidence will depend on several factors including the method and depths of dewatering. Accordingly, fu- ture maintenance and repairs to the subject residence should be anticipated. Respectfully submitted, NINYO & MOORE Robert T. Wheeler Avram Ninyo, GE.

APPROVED FOR CONSTRUCTION 11A7E.WI&A I-- OQ 12w,% ft T* tjc* fl b At the request ofrBcl Lsprite Builders, on January 31, 2009 we per rmed a structural inspection of both the 2 car and single car garages at the residence at 56840 ,Tac t tchl s Blvd. Uinta, California. The purpose of this inspection was to determine whether or not this garage structure is suitable for occupancy.' This home had experienced between 1 % and 7 inches of differential settlement and under went remediation by means of compaction grouting. That the emmplotion of the remediation process the structure was returned back to within I %a of an inch of its original as constructed elevation? The remediation process injected approximately 6, 500 cubic feet of eementitious grout into the underlying soil at various elevations to fill voids and compact areas of soft soils which otherwise would likely continue to experience varying amounts of subsidence overtime. As the voids were filled and the softer soils re -compacted the structure was gradually back up to the elevation mentioned above. During the remediation process extreme care was taken to monitor the upward movement of the entire structure. Those areas that had experienced the greatest amount of settlement were put at the top of priority list and addressed first. This was done in order to bring those areas with the greatest amount of settlement up to a point where the relationship among all of the foundations was nearly the same. Once this point was reached the remediation process began in earnest. The grouting program called for each area within the structure to he raised individually in a planned and systematic manner that would maintain all of the foundations in this near level relationship during the entire remediation program. This methodology was implemented in order to minimize the possibility of subjecting the structure to additional stresses which could possibly result in additional damage to the structure. As stated earlier at the completion of the remediation. project differential settlement had been reduced down to between %a and 1 A inches over the garage area. After the completion of the remediation program there arc only two conditions remaining that would suggest that some form of structural movement had occurred at this residence. Those two conditions are 1) the small amount of un -restored differential settlement with in the garage foundations, and 2) the 2 car garage outside wall between the right front corner adjacent to the 2 car garage door and the back wall of the garage is out of plumb at the top by approximately 1 to 1 %1 inches. Received Time Feb.17. 2009 2:40PM No.5537 41 'FROM :DANE-RODIN & ASSOCIATES, INC. FAX No. :949.348 141B . Feb. 17 2009 03:32P1 P3 5 ' To assure that this'out of plumb condition will not become a problem in the future we recommended that the garage shear walls be reworked to bring them back into compliance with the original design drawings for this home. We did not have a set of the original structural drawings for this home at the time of our inspection therefore, we relied on photographs of the garage that we took during our inspection to develop our recommendations. These photos were used to help us develop a set of shear wall strapping and hold down details (i.o., copies of those details aro attached) for Bel Esprite Builders to use in conjunction with the original structural details when restoring the garage shear walls. In developing our,recommendations a seismic analysis of this structure was not perfonred. Our recommendations/opinions are predicated on engineering judgment derived from the detailed visual inspection of the garage, 20 plus years of experience in designing homes in Southern California including the Palm Desert area, and extensive experience in stabilizing foundations by means of compaction grouting. Because this structure was not damaged a'sresult of a seismic event(s), but rather by the naturally occurring subsidence that has been ongoing in the greater Laquinta area for many years, we concluded that a seismic analysis of the structhere would not be . required. Additionally, there was nothing given to us that indicated that the original design and/or construction of this home was not in fu11 compliance with all of the prevailing building codes that were iri affect at that timelhis home was built. '!`herefore, our recommendation to rework the garage shear wails to bring them back into compliance with the original design with the addition of a couple of now drag tie details is in keeping with the facts that this structure had been performing 'as designed for many years with respect to wind and seismic loading criteria as set forth in the building codes. If these recommendations are implemented it is our opinion that this garage is suitable occupancy.

(Young Engineering) 78-495 Calle Tampico La Quinta, California 92253 Re: Structural inspection of the repairs to the home at 56-840 Jack Nicklaus, La Quinta California. A.J. and John; On March 26, 2009 I inspected the completed repairs made by Bel Esprite Builders to the garage and Casita at the residence referenced above. All of the repairs where found to be acceptable and in accordance with our letter to you dated February 12, 2009 and as we discussed in our phone conversations of March 22, 2009. The shear wall plywood diaphragm was not attached to all of the walls at the time of our inspection to allow us and your selves to inspect the structural rework that would otherwise be covered up if the plywood were nailed off in place. During our phone conversations on Monday March 22, 2009 the primary concern that we discussed was how to rework of the three walls that run from the front to the back within the two garage and Casita (i.e., one exterior wall at two car garage, one interior wall adjoining the two car garage and the Casita, and the short section of the Casita's exterior wall) that were left out of plumb after the pressure grouting. I have attached a copy of the detail that I believe addresses all of the concerns we discussed and which was used to rework/strengthen the three walls in question. It is instructive to note, that both the walls and trusses run in the same front to back orientation with the ends of the trusses bearing on perpendicular bearing walls or beams. Because of this particular orientation the three walls in question do not carry any of the roof load and for all intensive purposes are more like filler walls. The solution that we discussed over the phone was to establish a series of vertical under pins that could be built within the existing walls and attached to the existing studs in order to establish a vertical load path between the double top plate and the foundation. The detail attached represents that connection. It was verified in the field that the added 4x4's (i.e., which have essentially the same load carrying capacity as the 2x6's) do in fact provide the desired vertically plumb load path. With a proper load path established the walls will be re -sheeted following your inspection to restore the original shear wall configuration. Also, as part of the inspection the top plate splices were inspected as were the gang plates on the trusses to ascertain whether or not they had been damaged as a result of the subsidence? Upon inspection it was determined the gang plates had not pulled out nor had the wood truss members split or otherwise been damaged. The new hold downs were also inspected for proper installation and to assure that there was the required third party inspection during the setting of the anchor bolts. It was confirmed that the required third party inspection had been performed. We also inspected the foundations in the area of the garages and Casita to assure that the 4 foundations were not exhibiting visual signs of cracking, spalling, or deterioration. Our inspection did not note any areas of concern. Of concern originally was the extensive racking and movement of the two garage door openings (i.e., the single and two car garage doors). It was confirmed that these doors had been reworked per our recommendations/details, new vertical door header support columns had been added, new drag straps were added to tie the front openings to the adjacent shear walls, and new hold downs were installed at each side of the door openings. The drag strap details provided as part of our original submittal have all been incorporated in the reworking of this garage and Casita. After completing,our detailed, inspection it is our opinion that the rework performed by Bel Esprite Builders is in keeping with the intent of our rework recommendations and the intent of the original design. If you have any questions regarding this or anything else regarding the garages or Casita please or if you need any additional information please do not hesitate to call me.

I want to thank you for takin the time to talk 'th th' / g wi me is a regardm e subsidence restoration work that is being performed on the home at 56-8 ickla Quinta CA. After our conversation I did get a hold of John Thompson and we too had a good discussion about what is happening with that home. There has been some confusion as to what actions we need to take next, the conversations I had with both you and John this afternoon were a great help for me in clarifying what I believe are your expectations regarding what it is we are to be doing next. At the conclusion of my conversation with John here, is my understanding of what we agreed to that we would be doing next to complete this project; 1) The drag and shear wall details we provided in our initial submittal will be implement however, before any of the hold downs, drag straps, are covered up with shear wall panels, drywall, or stucco we will re -inspect each location within the garage to assure that the as installed condition matches the detail provided, 2) Before any of the work is covered up we will inspect all of the modifications for compliance to the details provided, 3) We will complete our review of the P -Delta conditions for the walls that are out of plumb in the garage (i.e., primarily the walls running front to back in the garage) and discuss our resolution with John Thompson prior to commencing any work in this area to assure we are all on the same page, 4) A complete inspection of the double top plate splices will be conducted and any required corrective action will be performed and documented as well as being referenced in the final Structural Observation Letter (i.e., the gang plates on the trusses have already been inspected and photographed and were found acceptable) 5) At the completion of all the work out lined here and in our initial submittal we will complete a Structural Observation Letter and forward it to your office, 6) Finally, we will keep you appraised of any changes in our findings and or restoration plans as they occur. I I again want to thank you for the assistance you have provided us and look forward to completing this project to every ones satisfaction. If the foregoing is different from what you thought we agreed to please call me at your earliest convenience.
