M � Mr. John McConaghy m � x April 28, 1989 rto The organic soils, surficial topsoil, looser overburden silty sand and localized fill soils will H be subject to significant compression under loads imposed by buildings and roadways and y parking areas. These soils should be removed from building areas and foundations should H be placed on the competent native soils or on compacted structural fill placed after removing organic and fill soils. Roadway areas underlain by these soft soils should also of be over -excavated to provide a minimnm of two feet of compacted structural fill below y d the pavement section. gDuring our study, we observed areas with heavy to moderate amounts of groundwater on z y the site near the creek. Control of water during construction and in the future will be a major factor in site development. Our study was performed after the wet winter period. gH y It is recommended that all grading and earthwork be performed during the drier summer N � e y months. The following sections of this report describe our study and explain our recommendations y oca y in greater detail. PROJECT DESCRIPTION ' Based on plans provided to us at the time our study was performed, we understand it is planned to construct eight one and two-story apartment buildings containing 107 units on the site. Depending on grading needed, some of these buildings may be provided with a crawl space while others may have slab -on -grade floors. The approximate building locations and configurations are shown on the Exploration Location Plan, Figure 2. This figure is based on an undated plan prepared and provided i to us by Charles Morgan and Associates. The buildings will be scattered around the property on both the east and west sides of North Creek. A recreation building is planned to be constructed on the west side of the creek. Parking areas and garages will surround the apartment buildings with access onto 7th Avenue to the east and 112th Street S.E. to the south. A covered walkway bridge will span North Creek. Dedicated City of Everett property will lie between the east and west project areas. �. Finish floor elevations and grading details were not known at the time of our study: However, we anticipate that minor cuts and fills in the range of approximately upto five feet may be needed in some portions of the site. Details of structural loads for the buildings are not known at this time. However, based i on our experience with similar structures, we anticipate that for tare two-story apartment buildings, loads of 2,000 to 3,000 pounds per lineal foot for continuous footings along perimeter walls and column loads on the order of upto 30 kips should be present. Once project site and grading plans have been finalized, they should be submitted to us for further review. At that time, supplementary recommendations may be given. Project No. T-1005 Page No. 2
