The design team for this project is: Western Engineer, Inc;. Barry R. Constant, P.E.; Project Manager, Civil Engineer, . Terra Associates;: Chuck Lie,'Geotechnical Engineer Reed and Associates, Inc.; Wendel Reed, Structural Engineer Landscape Architect; Jennifer Lee, Licensed Professional As the lead design Professional Engineer providing services to our client; Mr. & Mrs.' Brian Isaacson, my team and I have reviewed the geotechnical report and understand it's recommendations and have incorporated these design recommendations into the site civil design of this.project. The design parameters that my team and I' have designed for the civil drawings are using industry standard design measures to reduce the potential risk of injury or damage from any earth movement predicted in the report. Although the recommendations in the geotechnical report' will have been followed during the construction on this site, this engineer does not guarantee the long-term maintenance of these items. These maintenanceitems are under the control of the client and not under direct supervision by myself. Maintenance will be required as long •as there are no installed permanent solutions to the' landslide hazard area. And further: in my judgment, the plans and specifications prepared by the structural engineer conform .to the recommendations in the geotechnical report. LAND USE CONSULTANTS • CIVIL ENGINEERS 9 LAND SURVEYORS • ENGINEERING CORPORATION That the risk of damage to the proposed development, or to adjacent properties, from soil instability will be minimized subject to the conditions set forth in the report and that the -proposed development will not increase the potential for soil movement. Minimized shall mean that the applicant has utilized best available science and commonly accepted engineering and architectural practice to minimize, to the extent possible, the risks associated with development of the property. The risk of onsite soil movement in the building site area probability within the next 25 - years is appfoximately 12 percent. This is based on long-term study -by our team geotechnical engineer (Mr. Chuck Lie) who personally has studied this landslide hazard area.for 20 -years. By studying the various geotechnical reports issued for the site over the last 20 -years and using common and standard engineering practices for the erosion and sedimentation control, as well as the long term drainage solutions engineered and incorporated into the site will minimize land movement activities. Please see letter from the landscape architect for additional information The upper catchment wall, as designed by Reed and Associates, Inc. with assistance from Chuck Lie has been designed to stop low velocity landslide activated soils from contacting the house structure. An onsite deep boring was advanced in the area of the proposed wall. This wall has three feet of exposed wall above a very deep soldier pile support structure. The site is designed to allow a small, lightweight, powered or unpowered wheeled container to remove any soil spoils from the upper wall area and transport them down slope safely. This type of maintenance is not guaranteed by this letter. Please see letter from the landscape architect for additional information The Landscape Architect will provide deep-rooted planting that remove water from the loose upper soils on site. The landscaping will also provide small trees to provide the same function. Please see letter from the landscape architect for additional information The Landau Geotechnical report, dated 2007, identified certain areas as landslide hazards for this site and certain recommendations to reduce and minimize these hazards. Western Engineers in conjunction with Terra Associates have reviewed, designed and.approved the site engineering for the house structure location and elevations, retaining walls and catchment wall above the retaining walls. We have reviewed all structural and retaining I all footing drains and provided an extensive underground drainage conveyance system capable of removing and directing any runoff away from the house structure and retaining walls, down slope directly into the City drainage system on the roadway below the new house. Reducing and removing storm water runoff from the soils onsite is the number one risk reduction factor associated with earth movement. No one has control over the potential for shallow or deep-seated earthquake induced land movement, but we have reduced the ability of the land to move on pressurized (water pressure) underground soils, which could enhance additional land movement. The attached soil boring water levels and -the attached information regarding the piezometer r. reading all, indicate thatthe existing ground water levels has been reduced over time. Please call me nor any of the design team if you have questions regarding this letter. Sincerely, Western Engineers; Inc. p Barry onstant, P.E.

Supplemental Letter, Geotechnical Summary, Project No. T-840-10, prepared by Terra Associates, Inc., dated June S, 2009 Dear Mr. and Mrs. Isaacson: As requested, Terra Associates, Inc. (Terra) has provided geotechnical engineering services during construction of the subject project. We have provided consultation services during the planning, design, and permitting phases of this project. The referenced report and tetters contain our recommendations and discussion of the project. The purpose of our work was to verify that the geotechnical elements of the project design have been completed in accordance with recommendations outlined in our geotechnical report for the project. Our work was provided with periodic site visits coordinated with your contractor, Mr. Jim Arnold. We have previously submitted our field observations in memos that were sent to you, the contractor, and the City of Edmonds. 12525 Willows Road, Suite 101, Kirkland, Washington 98034 Phone.(425) 821-7777 • Fax (425) 821-4334 .• i Brian and Cindy Isaacson June 4, 2012 The city required the following elements in our observations services: 1. Soils (IBC 1704.7) The special inspections were conducted to verify compliance with the geotechnical recommendations in our referenced report and letters for the project that satisfy the requirements of IBC 1802 and the City of Edmonds requirements. 2. Soil Bearing Verification Terra made periodic site visits during construction. Representatives of Terra Associates verified adequate bearing for the foundations within the house footprint and for the upper catcluuent wall prior to placement of concrete. Adequate bearing was observed in the footing excavations for an allowable bearing pressure of 1,500 pounds per square foot. 3. Structural Fill Placement and Compaction/Placement Tena observed the placement of structural fill within the footprint of the house, along the eastern margin of the house for the foundation of the catchment wall, and behind the catchment wall. The lower -level basement wall was backfilled with site material compacted in place. Compaction testing and observations during fill placement indicated that adequate compaction was achieved. The upper basement wall along the east margin of the house was backfilled with crushed rock chips that were compacted in place with a vibratory sled compactor. The upper catchment wall was backfilled with clean sand and compacted in place with a vibratory. sled compactor. These upper two walls were backfilled using a conveyer belt boom truck to place material above the house footprint. The backfill for the two upper walls consisted of free draining soils. 4. Foundation and Site Draius/Footing Drains We observed that perforated footing drains and a separate tightiine for roof downspout drains were placed. We also observed that the basement walls were provided with a drainage board manufactured by Delta. Based on our observationsi the subsurface drains and downspout tightlines were placed in accordance with our recommendations and the project plans. We observed that the upper seepage zones were controlled during constnrction to reduce impacts on the area cleared for constnrction from the accumulated seepage. The pennanent site drainage features include a swale along the top of the catchment wall with two yard drains to collect surface runoff, the upper drainage network, yard drains in the patio area behind the house, and tightlines for the downspouts. All elements of the drainage system will need to be maintained over time. This includes keeping gutters clear of debris.

We observed that site activities did not create any site stability or erosion issues. We observed that visqueen was used to prevent erosion from precipitation. During our site visit, we did not observe any off-site transport of sediments. 6. Temporary Erosion Control We made periodic site visits during periods of time that site excavation or backfill operations were under way. We observed that site activities did not create any erosion issues. Following our site visit on January 23, 2012 following a snow melt and rain event, erosion control observations were taken over by Mr. Jim Arnold. No significant earthwork activities took place in the balance of the wet season. 7. final Erosion Control Final erosion control will be complete with the final re -vegetation plans. We have observed that the areas cleared in the past work on-site prior to 2011 have beers successfully re -vegetated. We have observed that the area disturbed for construction in 2011/2012 have had plants placed to reestablish erosion control. These plants will need to be maintained through the summer drought using hand irrigation. We do not recommend the installation of a dedicated irrigation system. We understand that you will place a permeable weed harrier fabric over the exposed soils to reduce the potential for erosion while the new ground cover is being established. 8. Site Retaining Wall/Rockery Construction No rockeries were constructed as part of this permit. We observed that the site retaining walls were placed as planned. Due to a conflict between the architectural plans and the structural plans, the contractor deleted the footing for the catchment wall that wrapped around the south east margin of the house. The structural engineer approved the variance from the plans in his rnerno dated May 31, 2012. 9. Excavations/Grading/Site Preparation We made periodic site visits during each step of the project excavation and grading. The soils exposed in the excavation were consistent with the soils anticipated Born our explorations and experience on the site. We observed the grading and site preparation was consistent with our recommendations for the project and the approved plans. 10. Final Letter This letter provides our fatal summary of the construction observations. All discussion in our prior reports remains applicable to this project. Project No. T-840-11 Page No. 3 Brian and Cindy Isaacson June 4, 2012 CONCLUSIONS Based on our observations during construction, it is our opinion that the geotechnical aspects of the project have been completed in accordance with the recommendations contained in our referenced geotechnical report, the construction drawings, and specifications as approved by the City of Edmonds. The only variation was the south end of the catchment wall as discussed Section 8 of this letter. We have attached the field memos that continent our site observations. All discussions and recommendations in our referenced letters and report remain applicable to this site. We trust the information presented is sufficient for your current needs. If you have any questions or require additional information, please call. Respectfully Submitted, TERRA ASSOCIATES, INC.

Brett called at about I I and reported that he had encountered seepage in the stair area excavation. I visited the site to observe the seepage. I recommended that the seepage be controlled with a sump and a pump to see if it is just a pocket of water. I also reviewed the exposed cut at the east side of the garage. It appears that there is sufficient room to cut it back to at least a 1:1, a sin;le high eblock wall can be placed at the toe of the cut to reduce the horizontal extent of the open cut. The eblocks can be left in place in the backfill if they do not interfere with keyways or other construction elements. Brett and I discussed the use of native soils for backfill. The sandy site soils would be suitable for use as wall backfill as long as the walls have been provided with drainage panels such as mira drains. TESC measures appear to be suitable.

If a trench is used, I recommended that the trench be backfilled with crushed rock such as the stockpile of pea gravel sized crushed rock that Brett had imported and stockpiled at the driveway area. No pipe would be needed in the trench. The trench should be as deep as possible to capture water from keyways. The same crushed rock could be placed at the base of ke)r%vays. no pipes should be placed in the kcyways. This crushed rock could also be used to provide a working surface on the bearing surfaces of footings if needed. The stability of the sidewalls of the key%vat's are the important clement. Observation of the seepage conditions Nvill need to continue to evaluate options for keyway construction in the lower areas of the lower floor where seepage has been observed. Spoils from the excavation continue to be exported. A stockpile of soils is present for use in backfill. TESL measures appear to be suitable. No off site sediment or water flow observed.

The flashing can be nailed to the concrete and glued with construction glue to the outside of the drainage board. This is to keep rocks and dirt from getting behind the drainage material. 2. Verify that there is 3 vertical feet of clear wall on the uphill side of the catchment wall.

While on-site we observed the following: • We observed the inside of each roof drain downspout with a TV/camera. All of the downspouts were tied.into tight line pipe directed to the storm drain system. The tight line pipe was partially crushed on near the entrance on the west side of the house. The plumber located the crushed section and indicated it was approximately two feet below current grade. Jun Arnold indicated the pipe would be fixed in the next day or two. We walked the site with Mr. Issacson to observe final erosion control measures still needing to be addressed. Permanent ground cover needs to be put in place on the north. south, and west sides of the residence. These areas were staked for ornamental landscaping at the time of our visit. Mr. Issacson indicated that the landscaping was scheduled to take place tofnorrow and topsoil and/or mulch was to be placed over any remaining exposed native soils. We recommended sloping topsoil away from the residence and any hardscaped areas (eg. sidewalks). We recommended rerouting water flowing from the tight line pvc pipe on the slope east of the house. The pipe can either be tight lined to the existing storm structure off the NE corner of the house upon approval of the city, or shortened to flow into the existing swale routing water to the south end of the site. • Growth on the slope covering the.majority of the east side of the property. is well established.
