Supplemental Lettcr, Geolechnical Summary, Project No. T-840-10, prepared by "Terra Associates, Inc., datcd June 5, 2009 Dear Mr, and Mrs, Isaacson: As rcquested,Terra Associates, Inc. (Terra) has provided geotecluilcal engirieering services during construction of the subject project, We have provided consultation services during the planning, design, An(] permitting phases of this project, The referenced report and letters contain our recommendations and discussion of the project, The purpose of our work was to verify that the geoteclmical elements of the project design have been completed in accordance with reconuncridations 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 koad, SUiW 101, Kirkl ind, Washington 98034 Phone (425) 821-7777 @ Fax (4).5) 821-4334 Brian and Cindy Isaacson June 4, 2012 The city required the following elements in our observations services: 1. Soils (ERC 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 catclunent 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 Ten -a 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 obsetations 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 tightline 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 observations, 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 construction to reduce impacts on the area cleared for construction from the accumulated seepage. The permanent 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. Project No. T-840-11 Page No. 2 Brian and Cindy Isaacson June 4, 2012 S. General Site'Nionitorinti During Wet Weather Construction 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 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 ivlr. Jini 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 been 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 barrier fabric over the exposed soils to reduce the potential for erosion while the new ground cover is being established. 8. Site Retaining WaRIIRockery Construction No rockeries were constructed as part of this permit, We obseivcd 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 memo 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 from 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 gcolechnical aspects of the prqject havc 0 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 catchnient wall as discussed Section 8 of this letter. We have attached the field memos that comment our site obsciwations. All discussions and recommendations in our referenced letters and report remain applicable to this site.

The mass excavation for the house is proceeding. I had postponed a routine weekly meeting with Jim Arnold at 10 ant for this date and we rescheduled it for the 28'h at 10 AM. 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 tite 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 I :1, a single 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 baekfill if they do not interfere with keyways or other construction elements. Brett and I discussed the use of native soils for baekfill, The sandy site soils would be suitable for use as wall baekfill as long as the walls have been provided with drainage panels such as mica drains, TESL measures appear to be suitable.

If a trench is used, I recommended that the trench be back -filled 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 \vater from keyways. The same crushed rock could be placed at the base of ke},\vays, no pipes should be placed in the keyways, This crushed rock could also be used to provide a \vorking surface on the bearing surfaces of footings if needed. The stability of the sidewalls of the keyways are the important clement. Observation of the seepage conditions will need to continue to evaluate options for- keyway construction in the lower areas of the louver floor where seepage has been observed.

Writer returned at 1200. Jim and Brian were on site. The concrete crew was arriving as I was on site. The southern half of the key way was being excavated while I was on site. Some light caving occurred and was removed while I was present. The soils exposed between the key way and the compacted crushed rock backfill for the house appear suitable for the support of the patio/footing as planned. Jim asked dif lie could do two pours on the patio slab thickness, the possible cold join in the patio would need to be discussed with the structural engineer. Brian and I walked up the slope. There is a tree that has fallen on the slope from tree cutting, I advised Brian to remove the tree and keep the slope accessible and visible for observations throughout the time he lives in his house. We discussed the need for the surface swale along the back of the catchment wall. This is on the plans and will need to be maintained over time. The catchment wall heights as planned appear to be OK. There will be a need to do sorne trimming of the slope immediately above the catchment hall to establish grade and the surface swale. Jim will shoot the area prior to forming the wall. Working safbty is important. Final temporary slopes will need to be triuinied to provide a safe work area for the wall crew. OK to place concrete in the keyway. Jim is planning on pulling the temporary wood shoring as the concrete is being placed.

Provide upper terminations for the drainage board that is exposed on the uphill side of the catchment wall and along the north foundation wall of the house. This can be done by cutting the drainage board close to or slightly below grade and placing a piece of Flashing over the top of the drainage board, The flashing can be nailed to the concrete and glued with construction -lue 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, The drainage from the seepage above the wall should be directed into the yard drains through surface swales. It is ok for the drainage to infiltrate for the time being but for the long term it needs to go to the yard drains. 3, 1 would like to verify that the downspouts are connected to the tight line, This can be done by lowering a sewer camera down the downspouts to verify that the pipe is not perforated.

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 tomorrow 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.
