(MGI) is pleased to submit this letter to provide a geotechnical assessment of the 4-foot high tiered rockery walls recently constructed on the west side of the subject property. We understand that evaluation of the walls is required as part of the permitting process. We previously prepared a Revised Geotechnical Engineering Report for this project, dated December 18, 2015. Additionally, MGI addressed several series of review comments by the City of Federal Way as this project progressed through the planning and construction phase. SITE CONDITIONS The project site consists of a narrow parcel located in the moderately populated Adelaide neighborhood of Federal Way, Washington, at the above address. The site spans approximately 138 feet from east to west and 777 feet from north to south; with the north end of the property terminating in Poverty Bay. 23rd Ave SW forms the western boundary of the south end of the parcel, with the roadway terminating approximately 190 feet north of the southern site boundary. An extension was previously added to 23rd Ave SW to serve as a personal driveway for a residential property northwest of the project area. This driveway enters the site initially trending towards the northeast, and eventually curves, exiting the site trending towards the northwest. The project area is bounded on the east and west by developed residential sites, with a new residence currently under construction immediately to the southeast.R ECi E VED NOV082017 Page 1 of 4 CSI FEDERAL WAY Monsef Donogh Design Group—Adelaide Lot 1B,29804 23rd Ave SW,Federal Way,WA November 3,2017 Geotechnical Rockery Assessment Letter P483-T15 Topographically, the south end of the site is comprised of the moderately sloped upland portion of the property, with much of the northern half of the site comprising of a steeply sloped (70 to 80 percent) hillside. This sloped portion of the site is part of a larger ridgeline which continues further west of the subject property, tapering out slightly towards the east. The center of the site, that which is occupied by the previously described driveway, forms a small spur in this larger ridgeline, with a draw in the overall topography being located immediately east of the spur. The upland extent of this draw is present in the subject property, and continues off site to the northeast. At the time of letter preparation, this project has largely been completed, with the new residence, utilities, and other amenities being constructed and/or installed. It is our understanding that the new construction has largely been performed in general conformance with approved site plans and specifications. The exception to this was the construction of an additional, tiered, 4-foot high rockery wall with associated fill soils, on the west side of the structure above the originally planned rockery wall. The two-tier rockery system was constructed in an effort to provide a more substantial, level, front yard space for the new residence. For this project, the rockery walls are being used as an erosion-protection facing against fill soils placed to level the yard. Accurate analyses of the rock facing is not possible due to the variability of rock sizes and contact areas, therefore the rockery walls should be constructed according to the recommendations presented below. Rockery Walls In our opinion, rockery walls can be used as an erosion-protection facing against stable fill embankments. We offer the following recommendations concerning rockery construction. Height Limitations: We recommend that rockeries constructed against stable fill embankments have a maximum height of 8 feet. Rockery Materials: Rockery wall boulders and chinking material should consist of hard, dense, sound, and durable rock, free from seams, cracks, and other defects in accordance with WSDOT Standard Specification 9-13.7(1). Backfill materials for rockery walls should consist of quarry spalls or shot rock of the same quality. Embedment Depths: For frost and erosion protection, as well as sliding resistance, the bottom course of all rocks should be founded in firm, unyielding soils at least 18 inches below the adjacent ground surface. The subgrade soil for the bottom course of rocks should be excavated, as necessary, to ensure full contact between the rock and soil surfaces. Rock Sizes and Placement: Rockery boulders should be placed in uniformly decreasing sizes from the bottom of the rockery to the top, with a battered face no steeper than 1H:6V. All boulders should be placed in running bond construction, with no continuous joint planes in vertical or lateral directions, and each rock should maintain at least two points of contact with Migizi Group,Inc.

The maximum void between adjacent rocks should be less than 6 inches as measured at the smallest dimension of the void; voids larger than 6 inches should be keyed with chinking rocks to fill the void. Drainage: To prevent the build-up of hydrostatic pressures, a free-draining backfill material should be provided behind the entire rockery. We recommend the use of ballast rock (1- to 2-inch quarry spalls) for this purpose. This backfill should be placed behind each boulder course and should extend at least 12 inches behind the rockery. Also, a perforated drain pipe should be placed along the heel of the rockery and be embedded in pea gravel or washed rock. This drainpipe should be routed to a catch basin or other suitable discharge point. CONCLUSIONS AND RECOMMENDATIONS On October 26, 2017, an engineering geologist from MGI performed a site visit to observe as-built conditions of the subject rockery. We noted that the rockery is comprised of well- stacked, basaltic rock units, with 12 to 18 inches of ballast rock installed between the fill embankment and rockery. MGI also confirmed that the backslope material is comprised of imported fill soils. No evidence of erosion or slope instability was observed along the alignment of the subject rockery. It is our opinion, based on our observations, that the subject rockery was installed in general conformance with the recommendations highlighted in the body of this letter, and should adequately prevent erosion and surficial sloughing. Given the geologic setting of the project site, and the limited vertical cuts performed in this area, we believe that the choice to construct a rockery versus a structurally engineered retaining wall to be appropriate, and we do not anticipate that any slope instability will be observed in this area throughout the lifespan of the subject rockery.
