Box 55502 Shoreline, Washington 98155 (206) 546-9217 FAX 546-8442 Michel Construction, Inc. / 8 1h Ave. S & Pine Street Pagetwo CHARACTERISTICS: A survey of the subject property was conducted on June 12, 2004 by L.S.A. The property is rectangular, and consists of approximately 62,510 frontage feet along the east side of 81h Ave. S and 179.26 frontage feet along the north side of Pine Street. The adjoining properties, as well as the neighborhood, consist of single family residences on similar size lots. The subject property contains mature trees, shrubs, and lowland grassy areas. The property is moderately sloped (less than 14%), and drains southwesterly to the existing wetland. EVALUATION: Visual assessments of the property at the N.E. corner of 81h Ave. S and Pine Street revealed no evidence of any geotechnical distress. No slides, no settlements, no creep, nor any significant erosional degradation were observed. This engineer has considerable experience in the immediate vicinity and understands the foundation subgrade conditions. Experience has proven that the subgrade soils are fully capable of properly supporting the proposed 8 new single family residences. This engineer evaluated the 8 1h Ave. S & Pine Street property on July 1, 2004. Significant clearing, grading, and drainage work had already occurred. (see photographs). The S.W. corner of the property is understood to be designated a W.Z., in accordance with drainage plans by Donna Breske, P.E. The utility work has exposed a large number of "soil test trenches" throughout the property.

Allowable bearing 0 pressure: 2,000 p.s.f. 0 M C 0) CO Q 0 Equivalent fluid pressure of 35 p.c.f. is recommended for any retaining .Z wall design provided drainage zone is inspected and verified by this engineer. Z • For retaining wall design, use friction factor of 0.55 and passive pressure of 350 p.c.f. Cn Z 0 • Geotechnical inspection by this engineer prior to any foundation concrete 0 placement. M The proposed structures can be supported on conventional continuous and spread footings bearing on undisturbed native soils or on structural fill placed above native soils. See the later sub -section entitled General Earthwork and Structural Fill for structural fill placement and compaction recommendations. Continuous and individual spread footings should have minimum widths of Michel Construction, Inc. 8" Ave. S & Pine Street Page four eighteen (18) and twenty-four (24) inches, respectively, and should be bottomed at least eighteen (18) inches below the lower adjacent finish ground surface. Depending on the final site grades, some overexcavation may be required z 0 below footings to expose competent native soils. Unless lean concrete is used to M fill the over excavated hole, the width of the overexcavation at the bottom must be at least as wide as the sum of two times the depth of the overexcavation and the footing width. For example, an overexcavation extending two feet below the 0 M C bottom of a three-foot wide footing must be at least seven feet wide at the base PH 0 of the excavation. 0 -40 0 Footings constructed according to the above recommendations may be C -4 X rn M z designed for an allowable soil bearing pressure of two thousand (2,000) pounds C _Z per square foot (p.s.f.). A one-third increase in this design bearing pressure may > be used when considering short -term wind or seismic loads. For the above � design criteria, it is anticipated that total post -construction settlement of footings o -n founded on competent, native soils (or on structural fill up to five (5) feet in thickness) will be about one-half inch, with differential settlements on the order of 3:9 M M one -quarter inch. Cl) 0 r, 0 M C Cn Lateral loads due to wind or seismic forces may be resisted by friction 9 Cn rn 0 between the foundations and the bearing soils, or by passive earth pressure Z acting on the vertical, embedded portions of the foundations. For the latter X condition, the foundations must either be poured directly against undisturbed soil or the backfill placed around the outside of the foundation must be level structural > fill. We recommend the following design values be used for the foundation's z resistance to lateral loading: z 0 Parameter Design Value i 0 M Coefficient of Friction 0.55 Passive Earth Pressure 350 p.c.f. Where: (1) p.c.f. is pounds per cubic foot. (2) Passive earth pressure is computed using the equivalent fluid density. Michel Construction, Inc. 8 1h Ave. S & Pine Street Page five A safety factor of at least 1.5 is recommended for design of the foundation's resistance to lateral loading. z 0 0 SLABS -ON -GRADE: Slab -on -grade floors may be supported on undisturbed, competent native CD 0 soils or on structural fill. The slabs may be supported on the existing soils M 0 provided these soils can be recompacted prior to placement of the free -draining 0 sand or gravel underneath the slab. This sand and gravel layer should be a 0 0 C minimum of four (4) inches thick. We also recommend using a vapor barrier M M z such as 6-mil. plastic membrane beneath the slab with minimum overlaps of 12 _Z inches for sealing purposes. C > PERMANENT FOUNDATION AND RETAINING WALLS: 0 -n M M Retaining walls backfilled on one side only should be designed to resist Cn lateral earth pressures imposed by the soils retained by these structures. The 0 r- 0 M following recommended design parameters are for walls less than twelve (12) C CD 9 Cn feet in height which restrain level backfill: M 0 Z Parameter Desian Value Active Earth Pressure* 35 p.c.f. z Passive Earth Pressure 350 p.c.f. X Coefficient of Friction 0.55 Cn z Soil Unit Weight 125 p.c.f. 0 M Where: (1) p.c.f. is pounds per cubic foot (2) Active and passive earth pressures are computed using equivalent fluid densities. For restrained walls which cannot deflect at least 0.002 times the wall height, a uniform lateral pressure of one hundred (100 p.s.f. should be added to the active equivalent fluid pressure). Michel Construction, Inc. 8" Ave. S & Pine Street Page six The values given above are to be used for design of permanent foundation and retaining walls only. An appropriate safety factor should be applied when designing the walls. We recommend using a safety factor of at least 1.5 for overturning and sliding. The above design values do- not include the effects of any hydrostatic pressures behind the walls -and assume that no surcharge slopes or loads will be placed above the walls. If these conditions exist, then those pressures should be added to the above lateral pressures. Also, if sloping backfill is desired behind the walls, then we will need to be given the wall dimensions and slope of the backfill in order to provide the appropriate design earth pressures. Heavy construction equipment should not be operated behind retaining and foundation walls within a distance equal to the height of the wall, unless the walls are designed for the additional lateral pressures resulting from the equipment. Placement and compaction of retaining wall backfill should be accomplished with hand -operated equipment. Retaining Wall Backfill Backfill placed within eighteen (18) inches of any retaining or foundation walls should be free -draining structural fill containing no organics. This backfill should contain no more than five (5) percent silt or clay particles and have no particles greater than four (4) inches in diameter. The percentage of particles passing the No. 4 sieve should be between twenty-five (25) and seventy (70) percent. Due to their high silt content, if the native soils are used as backfill, a drainage composite, such as Mirafi and Enkadrain, should be placed against the retaining walls. The drainage composites should be hydraulically connected to the foundation drain system. the purpose of these backfill requirements is to assure that the design criteria for the retaining wall as not exceeded because of a build-up of hydrostatic pressure behind the wall. The subsection entitled General Earthwork and Structural Fill contains recommendations regarding placement and compaction of structural fill behind retaining and foundation walls. z 0 1 0 M 0 0 C M M z _Z V) 0 -n M M 0 0 0 M C Cj) 9 CO M 0 z z 0 0 M Michel Construction, Inc. / 81h Ave. S & Pine Street Page seven EXCAVATION AND SLOPES: In no case should excavation slopes be greater than the limits specified in local, state and national government safety regulations. Temporary cuts up to a height of four (4) feet deep in unsaturated soils may be vertical. For temporary cuts having a height greater than four (4) feet, the cut should have an inclination no steeper than 1:1 (Horizontai:Vertical) from the top of the slope to the bottom of the excavation. Under specific recommendations by the geotechnical engineer, excavation cuts may be modified for site conditions. All permanent cuts into native soils should be inclined no steeper than 2:1 (H:V). Fill slopes should not exceed 1:1 (H:V). it is important to note that sands do cave suddenly, and without warning. The contractors should be made aware of this potential hazard. Water should not be allowed to flow uncontrolled over the top of any temporary or permanent slope. All permanently exposed slopes should be seeded with an appropriate species of vegetation to reduce erosion and improve stability of the surficial layer of soil. DRAINAGE CONSIDERATIONS: Footing drains are recommended at the base of all footings and retaining walls. These drains should be surrounded by at least six (6) inches of one -inch - minus washed rock wrapped in non -woven geotextile filter fabric (Mirafi 140N, Supac 4NP, or similar material). At the highest point, the perforated pipe invert should be at least as low as the bottom of the footing and it should be sloped for drainage. All roof and surface water drains must be kept separate from the foundation drain system. The excavation and site should be graded so that surface water is directed off the site and away from the tops of slopes. Water should not be allowed to stand in any area where foundations, slabs, or pavements are to be constructed. Any exposed slopes to be covered with plastic to minimize erosion. Final site grading in areas adjacent to buildings should be sloped at least two (2) percent away from the building, except where the area adjacent to the building is paved.

The stripped or removed materials should not be mixed with any materials to be used as structural fill. Structural fill is defined as any fill placed under the building, behind permanent retaining or foundation walls, or in other areas where the underlying soils needs to support loads. This engineer should observe site conditions during and after excavation prior to placement of any structural fill. All structural fill should be placed in horizontal lifts with a moisture content at or near the optimum moisture content. The optimum moisture content is that moisture content which results in the greatest compacted dry density. The moisture content of fill soils is very important and must be closely controlled during the filling and compaction process. The allowable thickness of the fill lift will depend on the material type, compaction equipment, and the number of passes made to compact the lift. in no case should the lifts exceed twelve (12) inches in loose thickness. The following table presents recommended relative compaction for structural fill: Location of Fill Placement Minimum.- RelativeCompaction Beneath footings, slabs or walkways 95% Behind retaining walls 90% Beneath pavements 95% for upper 12 inches of subgrade, 90% below that level Where: Minimum relative compaction is the ratio, expressed in percentages, of the compacted dry density to the maximum dry density, as determined in accordance with ASTM Test Designation D-1557-78 (Modified Proctor). Use of On -Site Soils If grading activities take place during wet weather, or when on -site soils are wet, site preparation costs may be higher because of delays due to rains and Z 9 0 M C M 0 -10 0 C -4 K X M M Z g) --I C C0 o -n n M M 0 5 0 r- 0 M C cl) 9 C/) Q 0 Z Z C/) Z 0 i 0 M I Michel Construction, Inc. / 8 1h Ave. S & Pine Street Page nine the potential need to import granular fill. The on -site soils are generally silty and thus are moisture sensitive. Grading operations will be difficult when the moisture content of these soils exceeds the optimum moisture content. Moisture sensitive soils will also be susceptible to excessive softening and 11pumping" from construction equipment traffic when the moisture content is greater than the optimum moisture content. Ideally, structural fill which is to be placed in wet weather should consist of a granular soil having no more than five (5) percent silt or clay particles. The percentage of particles passing the No. 200 sieve should be measured from that portion of the soil passing the three -quarter -inch sieve. The use of "some" on -site soils for fill material may be acceptable if the upper organic materials is segregated and moisture contents are monitored by engineering inspection. DRAINAGE CONTROLS: The overall property at 8 1h & Pine contains upsiope seepage. The road (8'h Ave. S.) has created a long term historical "dam". Thus, the S.W. corner of the property has become a man-made "moisture -zone". Drainage plans by Donna Breske, P.E. have incorporated intercept drains, tightlines and detention/ orifice mitigations. Geotechnically, this engineer will provide onsite inspections to verify proper foundation subgrade conditions exist prior to any concrete placement. CONCRETE: All foundation concrete (footings, stem walls, slabs, any retaining walls, etc.) shall have a minimum cement content of 5-1/2 sacks per cubic yard of concrete mix. INSPECTION: The recommendations of this report are only valid when key geotechnical aspects are inspected by this engineer during construction: Z 0 i 0 M =n- M M 0 0 0 M M Z ,C) --I C CD 0 -n n M M 0 Vi 0 r- 0 M C Cl) K C/) Q 0 Z Z 0 Z 0 0 M Michel Construction, Inc. 811 Ave. S & Pine Street Page ten Soil cuts Foundation subgrade verification Retaining wall, or rockery placement Any fill placement Subsurface drainage installation Temporary and final erosion control measures. SUMMARY: 1h & The proposed Michel Construction 8 lot SFR project at 8 Pine Edmonds, is geotechnically viable when constructed in accordance with the recommendations herein, compliance with City of Edmonds approved plans and requirements, and key geotechnical inspection during construction. CLOSURE: The findings and recommendations of this report were prepared in accordance with generally accepted professional engineering principles and practice. No other warranty, either express or implied, is made. The conclusions are based on the results of the field exploration and interpolation of subsurface conditions between explored locations. If conditions are encountered during construction that appear to be different than those described in this report, this engineer should be notified to observe the situation and review and verify or modify the recommendations.

Drawing showing location of 8 inch private storm drain line in City right of way. -i Water Facility Ownership and Maintenance Policy, 2. City of Edmonds Storn dated September 28, 2004 The site civil work for the development of the subject short plats by Rob Michel at 8"' Avenue South and Pine Street includes installation of a private stonn drain line from the private stonn water detention vault located on private property to the City stonn drain system catch basin in 8'11 Avenue South. Because of the site constraints (wetlands), approximately 82 lineal feet of 8 inch PVC private stonn drain line was installed in the City right of way on 8 Ih Avenue South. See Attachment 1. A question has been raised as to whether any type of permit or agreement is required for the City to authorize this private stonn drain line to be in City right of way and for the property owners to acknowledge ownership and maintenance responsibility for the line. City of Edmonds ---- . - -Ivt I Development Services Department Engineering Division 0 City standard procedures generally do not require any type ofpernlit other than a right of way construction permit for private storni drain lines to enter the right of way to connect to the City system. However, the more typical situation is that the private ston-n drain line is approximately perpendicular to the edge of the right of way and tile portion of the private storm drain line in tile right of way is only in the portion of the right of way that fronts the single private property which it serves. What makes this situation different is that the storni drain line in question is a considerable length of pipe installed parallel to the edge of the right of way. After reviewing this situation with the City Attorney, we have concluded that no additional permit or agreement is required based upon tile following facts and considerations: • The private storrn drain line is shown in the City right of way oil the approved civil plans. • During the review and approval of the civil plans, the developer originally proposed to install this storni drain line from the detention vault through the wetland to the City storm drainage system, but the City required tile storm drain line to be installed in the right of way to avoid disturbance of tile wetland. • The vast majority (all but a few feet) of the ston-n drain line that is in the right of way is in right of way that abuts the wetland tract, which is jointly owned by the private property owners of the development. Therefore, the vast majority of the underlying property within the right of way where the private storrn drain line is installed is jointly owned by the private property owners of the development. • City policy (Attachment 2) states that "Unless otherwise clearly and specifically indicated in a legally binding document which dedicates the facility to the City and which has been accepted by the City Council (e.g., plat, deed, etc.), storrn water facilities located within City right of way. —that serve... private property only shall be the ownership and maintenance responsibility of the private property owner(s) whose private property they serve, to the point where the facilities connect to the City owned ston-n water system." • The storm drain line in question serves all the private properties within the development, and only the private properties within the development. • The short plats do not dedicate this stonn drain line to the City and the City has not accepted ownership of it. Therefore, the storm drain line in question is clearly a private line, for which ownership and maintenance is the responsibility of the private property owners of the development, and no additional permit or agreement is required to authorize it to be in the City right of way or to document that it is the ownership and maintenance responsibility of tile private property owners. z 0 1 0 M --I -n M C M C) 0 0 0 C M M Z g) --i C —Z W o -n n M M 0 0 0 M C Cn 9 Cn M 0 Z z Cn z 0 1 0 M A I' CYc:1.
