This letter addresses item 11), as listed in the. Plan Review Comments letter from the City of Edmonds, Building Division, C dated March 17, 2005. In addition, the Plan Review Corrections letter dated March 24, 2005� requests our geotechnical response to items in the Edmonds Community Development Code Vi Q -n (ECDC), 23.80.020, 060 and 070. "n ��. I -' . Our original geotechnical evaluation, J-488, Proposed Residential, Development at rn M (3 Olympic View Drive and Home View Drive was dated July 21, 1999. The proposed revised 0 r rn plans reviewed were titled, Addition to Existing Residence, 18420 Homeview Drive, Edmonds C co: ic ca Washington and prepared by McJ of Redmond, Washington. In addition, we reviewed. mot geotechnical components of the submitted structural engineering items by Mitchell Engineering, Z Inc., requested by the City of Edmonds which were included in the revised plans. We understand a single story. sunroom addition, approximately 225 square feet in area and a deck, approximately 45 square feet in area,. are proposed at the northwest comer of the existing residence. An existing deck will be removed for the new construction. The addition will attach to the existing residence at the northwest comer. 0, Geotechnical Comments M The revised plans show a foundation plan with continuous footings for the proposed addition.. The north and est walls are to be supported by n ew continuous footings. The st w we half of the south wall and northernmost portion of the* east wall are also to. be supported by new continuous footings. The remaining portions of the east wall and the south wall will be founded atop the existing wall foundation. The plans.reviewed show a foundation plan on Sheet A-1 which also includes three continuous spread footings approximately 1.0 foot'wide and a minimum of 1.5 f6et in depth. Three spread footings, 2 feet square, are shown for the interior portion of the addition. 18905 33rd Avenue West#1 17; Lynnwood, WA 98036 (425) 771-3304 Fax: (425) 771-3549 ZZA Proposed Hibbert Sunroom Addition J -488-11 April 13, 2005 Page 2 MOM Our original geotechnical evaluation, J-488, included four shallow test pits which were deepened. by hand auger methods to depths of approximately 5 to 6 feet. The geotechnical study encountered loose topsoil up to 1.5 feet in thickness atop loose sand, interpreted as colluvium, to depths of 3.5 to 5 feet. Medium dense sand was noted below the loose sand to the bottom of the test holes. Test hole, HA-4 was advanced in close proximity to the location of the proposed addition. The medium dense sand horizon was encountered at a depth of approximately 5 feet in H -4, f A or our original study. We understand grading for the original site development included cuts at the northern portion of the residence on the order of 8 to 10 feet for the lower level garage. After the cuts, the M northern portion of the residence was founded on the medium dense sand. As discussed in our original soils report, the structure should be founded atop the medium dense sand or com acted p Co structural fill placed atop the medium dense,sand. M C M 0 Review of specific items requested by the Cit y of Edmonds, in Chapter 23.80 of 0 Geologically Hazardous Areas, included ECDC 23.80.020, Designation of Specific Hazard M Areas; ECDC 23.80.060, Development Standards -General Requirements and ECDC 23.80.070, M Z� Development Standards -Specific Hazards. Based on ECDC 23.80.020, the site has soils which may be an erosion hazard' and slopes in excess of 2H: IV (Horizontal:Vertical) may be' a landslide hazard. Our previous study, J-488 _n dated July 21, 1999, interpreted the soils to consist of the Indianola loamy sand of the Alderwood/ Everett Series. The Indianola sands are defined as a slight water erosion hazard. M M The portion. of the north slopewhich is greater than 211: IV is limited and a 25 botbufferwas 0 incorporated in the.original design. No evidence of deep-seated slope movement or springs, 0 C: cjj� seeps or wet areas were observed on the hillside during our original study in 1999 or during our ic CD site reconnaissance on April 5, 2005. M Z Based on ECDC 23.80.060, our previous study and current design,.the existing 25 -f ot ;a buffer will not increase the threat of the geological hazard to adjacent properties. No indications of deep-seated slope instability were observed on the property and provided proper construction Z techniques are utilized for the addition, it is our opinion that the construction will not adversely affect the overall stability of the slope. Z, Based on ECDC 23.80.070, the current 25-foot buffer will have no. adverse impact to the 0 s ite or the area of the proposed addition. The.proposed addition shall not result in greater risk or i rn a need for increased buffers on neighboring properties, in our opinion. Geotechnical recommendations in our original report should be implemented for the proposed addition. In summary, our review of the proposed revised plans for the addition and the, recommendations of the original geoteclinical report, J-488,,dated July 21, 1999 are still adequate for the proposed addition, in our opinion. Our involvement in the project will continue with special inspection services for foundation soil bearing for the proposed sunroom addition, as construction proceeds.

However, the upper soils on the slope 6onsisted of loose colluvi (slope wash) ium which is indi Icative of soil creep and erosion. Springs, steps or wet areas were not observed on, the hillside at. the time of our reconnaissance. Substirf&e -Conditions Subsurface conditions were explored by observing the soils exposed in four shallow test Z' 0: pits excavated by you prior to our field, visit on July 8, 1999. The test pits were concentrated in 0 the central and southern portions of the planned house location. On July 12, 1999, Zipper Zeman M Associates, Inc. utilized three of the test pit excavations to extend hand auger holes to depths 7, 9 between.5 and 6 feet below the ground surface. Dynamic cone penetration tests were performed in the holes to assess soil density characteristics. One additional hand auger h6le was adv ed anc C near the northwest comer of the planned rtsidence.

Page 4 too Based on our conversations with you, the northern portion of the residence will require cuts on the order of 8 to 10 feet, and the - existing sufface is near Ahe planned subgrade in the southern portion of the planned house, The soil conditions observed in the test holes indicate that the footings and floor slabs in the northern portion of the house will be founded on the medium dense sand. Loose, sand in the southern portion of the planned residence was observed to.extend to approxninately 3,5 feet below the existing ground surface. To reduce the potential for differential settlement of footings and floor slabs caused by spanni g across soils of variable n Z densityo werecommend that the loose colluvial subgrade sand in the building site that underlies footing and floor slabs be compacted to a minimum of 92 percent of the maximum dry density in 0 rp accordance with the ASTM D-1557 test. method. Alternatively, the loose soils should be removed below all footings.

All structural fill placed in building areas, and within the upper 2 feet in pavement areas, should be compacted to at least 95 percent of the maximum dry density (MD D) -n as determined by the ASTM D-1557 test method. Below a depth of two feet in pavement areas, 0 the structural fill should be compacted to a minimarn of 92 percent of the (MDD). This applies M to all utility, trench backfill as well.

Permanent cut slopes should be revegetated as soon as possible to reduce erosion and the susceptibility to sloughing, Constructed slopes for dziveway or foundation support should be keyed or benched into the existing slope. The top, outer edge of the constructed slope should be designed to provide a minimum separation of 10 feet from foundations and 5 feei from pavement surfaces, We recommend that the outer slope be constructed at a maximum inclination of 2:1 (H:V). Existin 9 soils below the constructed. slope that we loose or.disturbed should be excavated down to the z medium dense sand. The exposed subgrade should be prepared as described above. We recommend that the base of the excavated area be graded with a reverse (into the hillside) slope 0 M of I to 2 percent to -provide a key for the fill.

Residential Development July 21, 1990 Edmonds, Washington Page 7 Site grading and the construction of impervious structures (e.g. roofs, pavement areas) will alter drainage in the development area. We reconunend that site gnding allow for positive drainage away fyom * foundations and roadways. The concentrated runoff fiom, impervious, surfaces thould be directed to appropriate storm water discharge receptors and not allowed to Z flow down slopes. Concentrated storm water flow on slopes can lead to excessive erosion and compromise the stability of the slope. M Runoff from the -roof should not be concentrated and allowed -to fl ow over slopes. We :q 5i recommen d that roof runoff be.. collected in tightline pipes and directed to a suitable discharge receptor. C M All backfilled walls surrounding the structure should be provided with subsurface M 0 0 C ainage. dr i To protect'wills and floors from moisture and to avoid, the buildup of hydrostatic (_.pqqsurcs, y�pygKpmmend that the backfill material within 36 inches outside backfilled walls and M M Z 1. A?�fi4?Tjdie full7htight of the wall consist of clean, free -draining sand and gravel. Washed or 10-1 screened -gravel could be substituted for sand and gravel drainage, material, ri provided 111ter fab c is placed to separate the waahed gravel from adjacent site.soils of fill. The backfill should be sealed at the ground surface with a minimum of I foot of impervious soil in any unpaved areas to 0 n prevent surface water from entering directly into the wall backfill. Final site grades should be designed to �arry water away from the struc -rom a ture in order to prevent it f ccumulating and m M ponding next to the -structure. .0 CO) At the base of backfilled walls, we recommend 'roviding footing drains. The footing p 0M C Cn ic (n drains (,With cleanouts) should consist of perforated pipe, sloped to drain, with ped6rations M 0 Z F_ placed down. Mic free -draining backfill adjacent the backfilled walls should be c inuous and ont envelop the footing drains for at least 6, inches in all directions. Roof drains should not be conriected to the subdrains. M Z USE OF.
