Doyle, G.I.T. WEATHER: Overcast, windy, -38 °F PURPOSE OF VISIT: Rockery Wall Observation Carlson Geotechnical (CGT) staff Debra Doyle arrived on site at 0800 hours as requested by Steve Hunt of Renaissance Homes (RH)_ The purpose of my visit was to observe the removal and rebuilding of the two upper rockery walls located at the back of lot 5. I met with Keith and Aaron of Curtis Heintz Excavation (CHE) on site. The rockery walls will be removed and reconstructed in sections due to space limitations because of the existing structures on site. Two more sections of wall 2, approximately 50 feet total, were removed and reconstructed during my visit today. Upon removal of each section, the original subgrade was probed. There was no keyway beneath the original rockery wall. A keyway was excavated to 1.5 feet, and the newly exposed subgrade was also probed. The keyway was then covered with 6 inches of 1 -1/2 inch drain rock, and lightly compacted using the backhoe bucket. As each section of wall was rebuilt, each row of boulders was backfilled with 1 -1/2 " drain rock, and compacted with the backhoe bucket. The reconstructed wall is approximately 4 feet in height and generally has a batter of 1 H:4V. After each section of rockery wall 2 was removed, I probed the original subgrade, and then the 1.5 -foot deep keyway using a '/2 inch steel foundation rod. On the original subgrade I could penetrate up to 1 foot. The keyway was over excavated to 2.5 feet. I robed the over excavated keyway and could not penetrate the subgrade more than 1 inch in any location, indicating stiff conditions_ There was the same 4" minus rock in the soils in this 50 foot section as was reported in the field report dated 1- 08 -03. The owner of Lot 5 requested that the upper rockery wall not be reconstructed so that there would be more yard. I recommended to Steve (RH) that the ground surface be horizontally level for 5 feet from the deck footings outward, then a 2H:1 V slope to the top of the new rockery wall 2 can be constructed_ I left the site at 1415 hours due to a maintenance problem with the backhoe. Arrived back on site at 1530 hours. At the end of the day, only the first course of boulders was placed in the keyway of the remaining 10 feet of the reconstructed rockery wall. Based on my observations and probing, the rockery wall reconstructed to this point has been prepared in general accordance with project plans, and our recommendations. I left the site at 1715 hours.

At your request, we observed the reconstruction of the two upper rockery walls to evaluate whether they were constructed in accordance with the standards of practice for rockery wall construction, our standard recommendations for rockery wall construction, and the rockery wall design provided by Carlson Testing, Inc. (CTI) for the subdivision walls_ Only one of the original two upper rockery walls was reconstructed. At the homeowners request, the upper rockery wall was removed, but not reconstructed. In its place, the upper portion of the backyard was regraded to CTI's specification. Based on our observations, the one upper rockery wall on lot 5 was reconstructed in accordance with CTI's recommendations and the standards of practice for construction of rockery walls.

The purpose of my visit was to observe the regarding of the backyard of lot 5, I met with Keith Curtis Heintz Excavation (CHE) on site As requested by the homeowner, the upper rockery wall (wall 1) had not been rebuilt. In its place, the yard had been graded to conform to our recommendation to Steve (RH) that the ground surface be horizontally level for 5 feet from the deck footings outward, then a 2H:1 V slope to the top of the new rockery wall 2 can be constructed. I did not observe the regarding, but returned at completion of the task and took measurements. The level area from the deck footings (10H :1 V) and the slope (2.7H:1 V) were measured and found to be within the recommended parameters. Based on my observations the regarded soil has been prepared in general accordance with project plans, and our recommendations. I left the site at 0910 hours. A Debra L. Doyle, G.I.T. Je. ne M.

At the time of my visit, the proposed residence was In the final stages of framing, I observed that the residence was set back from the rockery walls from 15 to 26 feet. I also observed that there were five rockery walls at the back of the lot approximately four feet high and stepped up at approximately a 4- foot setback from each other_ I also observed that there are rook emirs that run from the top of the highest wall down through the walls to gain access to the bottomback of the lot.

On the original subgrade I could not penetrate more than 1 inch in any location, except for a 1 -foot by 1 -foot area near the east end of wall 2, where I could penetrate the subgrade from 8 to 10 inches. I probed the keyway and could not penetrate the subgrade more than one inch in any location, indicating stiff conditions. There was some 4" minus rock in the soils approximately two feet behind the original footprint of rockery wall 2. Aaron (CHE) stated that they believed there was a storm drain installed at depth, and had been backfilled with the 4" minus rock. It had not been used as backfill behind the original rockery wall 2. There was also some minor ground water seepage approximately in the same general location as the base of the 4" minus rock_ Based on my observations and probing, the rockery wall reconstructed to this point has been prepared in general accordance with project plans, and our recommendations.

The purpose of my visit was to observe footing subgrades conditions for lot number 5 of Erickson Heights Subdivision, At the time of my visit, the proposed residence had been ixc3vated 'down to footing subgrade elevation and the corners of the footings had been staked. The kilis.,consisted of brown silt with trace gravels and cobbles. I observed that the subgrade soils were relatively free of organic matter or other deleterious materials. I also observed that the lot slopes down hill from north to south at less than a 21.1: 1V and the front half of the proposed residence had been benched from north to south. I probed the footing subgrade soils with a W diameter steel foundation rod. in general I was unable to penetrate the subgrade soils more then 1 inch with moderate pressure, indicating stiff to very stiff soil conditions. A I observed at the front middle of the proposed residence (north) a 6 -foot vertical out face and one footing with a :6iin&i setback from a 2 -foot vertical cut face, above the 6 -foot vertical cut face. Per a phone call from Steve Hunt of Renaissance Homes I understand that a retaining wall is proposed at the base of the 6 -foot vertical cut face and the footings will also, be thickened at this location. • Based on my observations, the footing subgrade soils observed today, have been prepared In general accordance with our recommendations. I left the site at 0855 hours. - ob rt L. Russell, E.I.T. Je nne M.
