Spence 2720 - 210" St SW Lynnwood, Washington 98036 RE: Bearing Soil/Foundation Preparation — Garage Area NE Corner 35`t' St. and Nassau St., Everett, Wa. City of Everett Project #REV104-017 Dear Mr. Spence; 04-08-10 (2cq H -C)G ( As requested, an engineering geologist from GES, Inc. visited the above referenced project site on April 11. 13 and 14, 2005 to view site conditions and confirm bearing soil/foundation preparation for the garage area. This work was being done after the completion of tie main house foundation per the recommendations contained in our letter dated March 1. 2005. cite _onstraints as outlined in the referenced letter resulted in limited options for the placement of the footings for the garage foundation. This will result in the garage footings having to be placed on both undisturbed natural soil and upon varying amounts of foundation backfill. This will increase differential settlement potentials over normal for the garage area. Bearing walls for the garage foundation are along the north and south footings. The east and west footings are for non -bearing walls. The north garage wall will be tied into the existing basement foundation wall for the residence. The south garage wall will bear upon undisturbed natural soil. The east and west footings will be placed upon a minimum two-(2) foot thick crushed rock mat and the% will reinforced to help limit local settlement potentials. To further help stiffen up the east and west footings in the immediate vicinity of the basement foundation, we recommend that they be tied into the basement foundation wall with reinforcement steel. We further recommend that the garage floor slab be structural. with the reinforcement being tied into the basement foundation wall to the north and the footing/stem wall along the south foundation line.
