Reference benchmark and elevations are noted on the plans. 13. All disturbed areas shall be seeded and mulched or otherwise stabilized to the satisfaction of the Department for the prevention of on -site erosion after the completion of construction. 14. All pipe and appurtenances shall be laid on a properly prepared foundation in accordance with the standards and specifications of the City of Renton Planning/Building/Public Works Department and the latest edition of the WSDOT/APWA Standards and Specifications, as approved and modified by the City of Renton in the Renton Standard Plans & Specifications.

In unimproved areas, manhole to extend minimum 6 inches and maximum 12 inches above finished grade or must have minimum 2' diameter concrete ring poured at grade. In paved area, cover must slope in all directions to match paving. Site Preparation and Earthwork The primary geotechnical considerations with respect to earthwork are related to the outdoor parking lot structure excavation, temporary slope construction, and foundation subgrade preparation for the main building structure. The soils encountered in the building excavations should largely consist of loose silt and sand deposits throughout the western portions of the proposed structure which transitions to medium dense to dense native deposits throughout the eastern portions of the proposed structure. The native silt deposits can be characterized as having a generally moderate to high sensitivity to moisture. Excavations As excavation of the outdoor parking lot structure progresses, the soil relative density should generally increase and is expected to exhibit good stability in open cut excavations. Localized perched zones of groundwater seepage should be expected in the outdoor parking lot structure excavations. Overall stability cf the excavation is anticipated to be good, provided appropriate means for sloping or shoring the excavation are utilized. Based on the soil conditions observed at the test sites, the following allowable temporary slope inclinations can be used: • Loose to Medium Dense Native Soil 1 H:1V (Horizontal:Vertical) • Dense to Very Dense Native Soil* 0.51­1:1V to 0.75H:1V** * Based on data obtained during the subsurface exploration, the native silt soils should become dense to very dense at a depth of approximately five feet below existing grades. ** Steeper temporary slope inclinations of 0.25H:1V may be feasible based on actual conditions encountered, and based on observation and approval by the geotechnical engineer. The geotechnical engineer should observe the excavations and assess the allowable temporary slope inclination based on the soil and groundwater conditions exposed in the excavations. Supplement recommendations for sloping the excavations may be made by the geotechnical engineer based on conditions observed. Structural Fill We anticipate structural fill placement will generally be required behind foundation walls and within utility trench excavations. Structural fill may also be necessary in slab -on -grade areas, Due to the building load and bearing capacity requirements, the building foundations should be founded directly on competent native soils, or two-inch crushed rock immediately underlain by competent native soils (where overexcavation in lieu of aggregate piers is utilized). Where structural fill is utilized outside foundation areas, a suitable granular soil with a moisture content that is at or near the optimum level should be used. The native soils can be considered for use as structural fill provided the soil is at or near the optimum level at the time of placement. The native soils have a moderate to high sensitivity to moisture, and will become unstable if exposed to excessive moisture. If the native soils cannot be successfully compacted, the use of an imported soil may be necessary. Imported soil intended for use as structural fill should consist of a well graded granular soil with a moisture content that is at or near the optimum level. During wet weather conditions, imported soil intended for use as structural fill should consist of a well graded granular soil with a fines content of five percent or less defined as the percent passing the #200 sieve, based on the minus three-quarter inch fraction. Structural fill is defined as compacted soil placed as wall backfill and in slab -on -grade, utility trench, and roadway areas. Soils placed in structural areas should be compacted to a relative compaction of 90 percent, based on the maximum dry density as determined by the Modified Proctor Method (ASTM D-1557-02) and placed in maximum 12 inch lifts. In pavement areas, the upper 12 inches of the structural fill should be compacted to a relative compaction of at least 95 percent. As indicated above, structural fill placed below foundation elements should consist of two-inch crushed rock immediately underlain by competent native soils.
