We visited the site today at the request of Mike Todd with Todd Homes to evaluate construction
activities at the Gold Residences project located in 16620 — 75th Place West in Edmonds, A.
Upon arrival, we met with Mike. We observed that driveway area had been graded to the approximate
subgrade of the concrete driveway. Some surficial mud and standing water was observed throughout the
driveway area. We evaluated the driveway subgrade with a 1/2 -inch diameter steel probe rod. Probing
generally yielded penetrations of I to 2 inches within the upper portion of the driveway, indicating
medium dense to dense conditions. However, the lower portion of the driveway near the residences
generally probed 12 to 18 -inches under moderate pressure indicating very soft conditions. We
recommend that this area be overexcavated a minimum 18 -inches to expose competent native soils. The
overexcavation should then be covered entirely with a heavy duty unwoven filter fabric such as Mirafi
140N or equivalent and backfilled with crushed rock. The crushed rock should be compacted in place to
an unyielding condition. We will return to observe the overexcavation and backfill of the soft areas.
We have been providing monitoring services on a part-time basis only. Our findings and conclusions
are based on construction activities observed while on site.

We visited the site today at the request of Mike Todd with Todd Homes to evaluate construction
activities at the Gold Residences project located in 16620 — 75h Place West in Edmonds, WA.
AM Visit
Upon arrival, we met with Mike. We observed the overexcavation of the lower driveway, as shown on
attached site plan. A 10 ft. by 10 ft. area at the southeastern portion of the driveway was overexcavated
approximately 20 in. to expose gray -brown silty sand with gravel. The rest of the area was taken down
approximately 8 to 12 inches, exposing the same material. We evaluated the soil using a 1/2 -inch
diameter steel probe rod. Probing generally yielded penetrations of up to 3 inches, indicating medium
dense or better conditions and should provide adequate support for the planned loads.
PM Visit
Upon arrival, we observed that the contractor had placed 2- to 4 -inch rock spalls in the deeper
overexcavation in the southeast comer. They had also covered the whole overexcavation with Amoco
4545 non -woven filter fabric. We will be back tomorrow to evaluate the 5/8 -inch minus crushed rock
which will be compacted on top of the filter fabric.
We have been providing monitoring services on a part-time basis only. Our findings and conclusions
are based on construction activities observed while on site.

We visited the site today at the request of Mike Todd with Todd Homes to evaluate construction
activities at the Gold Residences project located in 16620 — 75"' Place West in Edmonds, WA.
Upon arrival, we observed that 5/8 -inch minus crushed rock had been placed over the filter fabric. It was
compacted using a walk behind plate compactor. We evaluated the subgrade using a '/2 -inch diameter
steel probe rod. Probing generally yielded penetrations of up to 2 inches, indicating medium dense or
better conditions and should provide adequate support for the planned loads.
