Bruce, P.E., with calculations • Drainage design by D. Bruce, P.E., dated October 23, 2000 • Correction Notice / Comments from City of Edmonds As indicated on the drainage design plan and as commented by City of Edmonds, the project proposes to bypass the detention vault with the entrance and parking area driveway zone. The modifications of this report and revised, calcutations respond to that driveway bypass area. Assuml2tions: - The existing conditions are assumed to be thick grass or meadow. The existing (pre -developed) impervious area contribution is ignored (per City of Edmonds requirements), even though in reality, the site currently contributes significant impervious runoff. LJJL) t The storm detention required s the 1 0-year an 00-year undeveloped match based on City of Edmonds drai n 18.30.060 (1) (c). ,Eiii tor Soil conditions were assumed to be Type C, such as Alderwood or Tokulgsl - Hydraulic Group "C".

Re: 658 Glen Street Pagetwo • Assume CN initial to be .81 for grass. • Assume CN final to be .8.5 for landscaped areas and .98 for rooftop. L-1 = one hundred forty feet (140') at a slope equal to 0.0222. T(c) = 26.16 minutes P (2-year) = 1.5 inches per hour P (1 O-year) = 2.1 inches per hour v k" P (1 00-year) = 3.2 inches per hour 0 Proposed impervious area = 10,364 square feet (or 0.24 acres) Proposed pervious area = 6,136 square feet (or 0. 14 acres) In order to correct for the driveway bypass of the two required design storms (1 0-year, and 1 00-year), the runoff from the driveway area must be estimated by the SBUH method. This peak flow must be subtracted from the Q-allowable discharge from the detention vault. Note: It is this engineer's opinion that for areas this small, the level of detail required is beyond the accuracy limits of the model. The reduction and release rate from the detention vault to compensate for the driveway bypass will result in smaller orif ices than previously calculated, and an increase in the size of the detention vault. In the previous design, the following release rates were utilized: 0-allowed, 0-develo2ed 0-vault Lelgase 2-year 0.009 CFS 0.080 CFS 1 0-year 0.030 CFS 0. 125 CFS 0.030 CFS I 00-year 0.088 CFS 0.211 CFS U84 CFS City of Edmonds has responded by requiring a correction for the bypass created by diverting 0.04 acres of driveway directly into the storm system because of non - constructible elevations required to service this project. Michel Construction, Inc. Re: 658 Glen Street Page three KI SBUH Hydrographs provide the following description of the driveway runoff conditions: 1 0-year developed runoff = 0. 016 CFS I 00-year developed runoff = 0. 025 CFS Q-10 allowed = 0.030 - 0.016 = 0.014 CFS Q-1 00 allowed = 0.084 - 0.025 = 0.059 CFS Thus, the area of bypassed driveway is subtracted from the entire site area by Virtue of the bypass of 0.04 acres.. The new developed site area is: 0.38 acres - 0.04 acres = 0.34 acres. "D M- F111-.311-1 Recalculations of the SBUH site model results in the following conclusions: The vault outlet invert remains at elevation 93.35 (with a vault floor at least eighteen inches [18"] lower to allow for the stand pipe of the restrictor structure). Orifice No. I diameter is now reduced to 0.517 inches (or approximately 0.5 inches). Orifice No. 2 diameter is now changed to 1.682 inches at elevation 97.15. - The overflow elevation will now be 97.5. The existing vault design will be increased to a new length of thirty feet (30'). The vault width remains at eight foot (8'), and a structural inside depth of six and one-half feet (6.5'). Michel Construction, Inc. Re: 658 Glen Street Page four • The driveway bypass flow has been calculated for the design storm events. • The bypass Q has been subtracted from the Q-allowed (or undeveloped Q). • The designed release rates have been reduced by the amount of bypass runoff. • Storm detention has been Increased to accommodate the reduced releases. • City of Edmonds issues have been addressed. • See revised drainage design dated October 30, 2000.

September 27, 2000 drainage report by D. Bruce, P.E., with calculations Drainage design by D. Bruce, P.E., dated October 23, 2000 Correction Notice / Comments from City of Edmonds As indicated on the drainage design plan and as commented by City of Edmonds, the project proposes to bypass the detention vault with the entrance and parking area driveway zone. The modifications of this report and- revised calculations respond to that driveway bypass area. - The existing conditions are assumed to be thick grass or meadow. The existing (pre -developed) impervious area contribution is ignored (per City of Edmonds requirements), even though in reality, the site currently contributes significant impervious runoff. The storm detention required is the 1 0-year and 1 00-year undeveloped match based on City of Edmonds drainage code, Section 18.30.060 (1) (c). Soil conditions were assumed, to be Type C, such as Alderwood or Tokulgsl - Hydraulic Group "C". SOILS - FOUNDATIONS - SITE DEVELOPMENT - INSPECTION - DRAINAGE - DESIGN & PERMIT - LEGAL P.O.

Re: 658 Glen Street Pagetwo • Assume CN initial to be .81 for grass. • Assume CN final to be .8.5 for landscaped areas and .98 for rooftop. L- 1 = one hundred forty feet (140') at a slope equal to 0.0222. T(c) = 26.16 minutes P (2-year) = 1.5 inches per hour P (1 O-year) = 2.1 inches per hour P (1 00-year) = 3.2 inches per hour Proposed impervious area = 10,364 square feet (or 0.24 acres) Proposed pervious area = 6,136 square feet (or 0. 14 acres) In order to correct for the driveway bypass of the two required design storms (1 0-year, and 1 00-year), the runoff from the driveway area must be estimated by the SBUH method. This peak flow must be subtracted from the Q-allowable discharge from the detention vault. Note: It is this engineer's opinion that for areas this small, the level of detail required is beyond the accuracy limits of the model. The reduction and release rate from the detention vault to compensate for the driveway bypass will result in smaller orif ices than previously calculated, and an increase in the size of the detention vault. In the previous design, the following release rates were utilized: 2-year 0.009 CFS 0.080 CFS I 0-year 0.030 CFS 0. 125 CFS 0.030 CFS 1 00-year 0.088 CFS 0.211 CFS 0-084 CFS City of Edmonds has responded by requiring a correction for the bypass created by diverting 0.04 acres of driveway directly into the storm system because of non - constructible elevations required to service this project. Michel Construction, Inc. Re: 658 Glen Street Page three SBUH Hydrographs. provide the following description of the driveway runoff conditions: I 0-year developed runoff = 0. 016 CFS 1 00-year developed runoff = 0.025 CFS Balance of Allowed Runoff from Detentlon Vault: Q-10 allowed = 0.030 - 0.016 = 0.014 CFS Q-1 00 allowed =* 0.084 - 0.025 = 0.059 CFS Thus, the area of bypassed driveway is subtracted from the entire site area by virtue of the bypass of 0.04 acres. The new developed site area is: 0.38 acres - 0.04 acres = 0.34 acres. Recalculations of the SBUH site model results in the following conclusions: The vault outlet invert remains at elevation 93.35 (with a vault floor at least eighteen inches [18"] lower to allow for the stand pipe of the restrictor structure). Orifice No. I diameter is now reduced to 0.517 inches (or approximately 0.5 inches). - Orifice No. 2 diameter is now changed to 1.682 inches at elevation 97.15. - The overflow elevation will now be 97.5. The existing vault design will be increased to a new length of thirty feet (30'). The vault width remains at eight foot (8'), and a structural inside depth of six and one-half feet (6.5'). C-' (' Michel Construction, Inc. Re: 658 Glen Street Page four • The driveway bypass flow has been calculated for the design storm events. • The bypass Q has been subtracted from the Q-allowed (or undeveloped 0). The designed release rates have been reduced by the amount of bypass runoff. Storm detention has been Increased to accommodate the reduced releases. - City of Edmonds issues have been addressed. - See revised drainage design dated October 30, 2000.

Bruce, P.E., with calculations • Drainage design by D. Bruce, P.E., dated October 23, 2000 • Correction Notice /Comments from City of Edmonds As indicated on the drainage design plan and as commented by City of Edmonds, the project proposes to bypass the detention vault with the entrance and parking area dfiveway zone. The modifications of this report and- revised- calculations respond to that driveway bypass area. - The existing conditions are assumed to be thick grass or meadow. The existing (pre -developed) impervious area contribution is ignored (per City of Edmonds requirements), even though in reality, the site currently contributes significant impervious runoff. The storm detention required is the 1 0-year and I 00-year undeveloped match based on City of Edmonds drainage code, Section 18.30.060 (1) (c). Soil conditions were assumed to be Type C, such as Alderwood or Tokulgsl - Hydraulic Group "C". SOILS - FOUNDATIONS - SITE DEVELOPMENT - INSPECTION - DRAINAGE - DESIGN 41 PERMIT - LEGAL P.O.

Re: 658 Glen Street Pagetwo - Assume CN initial to be .81 for grass. - Assume CN final to be. 85 for landscaped areas and .98 for rooftop. L-1 = one hundred forty feet (140') at a slope equal to 0.0222. T(c) = 26.16 minutes . P (2-year) = 1.5 inches per hour P (1 O-year) 2.1 inches per hour P (100-year) 3.2 inches per hour Proposed impervious area = 10,364 square feet (or 0.24 acres) Proposed pervious area = 6,136 square feet (or 0. 14 acres) In order W correct for the driveway bypass of the two i-equired design storms (1 0-year, and 1 00-year), the runoff from the driveway area must be estimated by the SBUH method. This peak flow must be subtracted from the Q-allowable discharge from the detention vault. Note: It is this engineer's opinion that for areas this small, the level of detail required is beyond the accuracy limits of the model. The reduction and release rate from the detention vault to compensate for the driveway bypass will result in smaller orif ices than previously calculated, and an increase in the size of the detention vault. In the previous design, the following release rates were utilized: 0-allowed. Q-develg2ed Q-vault release 2-year 0.009 CFS 0.080 CFS 1 0-year 0.030 CFS 0. 125 CFS 0.030 CIFS 1 00-year 0.088 CFS 0.211 CFS 0.084 CFS City of Edmonds has responded by requiring a correction for the bypass created by diverting 0.04 acres of driveway directly into the storm system because of non - constructible elevations required to service this project. 'e . Michel Construction, Inc. Re: 658 Glen Street Page three "D dVL:Y"'1-XA;1 SBUH Hydrographs provide the following description of the driveway runoff conditions: 1 0-year developed runoff = 0.016 CFS 1 00-year developed runoff = 0. 025 CFS Q-10 allowed = 0.030 - 0.016 = 0.014 CFS 0-100 allowed = 0.084 - 0.025 = 0.059 CFS Thus, the area of bypassed driveway is subtracted from the entire site area by Virtue of the bypass of 0.04 acres.. The new developed site area is: 0.38 acres - 0.04 acres = 0.34 acres. Recalculations of the SBUH site model results in the follovAng conclusions: - The vault outlet invert remains at elevation 93.35 (with a vault floor. at least eighteen inches [181 lower to allow for the stand pipe of the restrictor structure). Orifice No. 1 diameter is now reduced to 0.517 inches (or approximately 0.5 inches). - Orifice No. 2 diameter is now changed to 1.682 inches at elevation 97.15. - The overflow elevation will now be 97.5. The existing vault design will be increased to a new length of thirty feet (30'). The vault width remains at eight foot (8'), and a structural inside depth of six and one-haif feet (6.5'). Michel Construction, Inc. Re: 658 Glen Street Page four • The driveway bypass flow has been calculated for the des1gn storm events. • The bypass Q has been subtracted from the Q-allowed (or undeveloped Q). • The designed release rates have been reduced by the amount of bypass runoff. • Storm detention has been Increased to accommodate the reduced releases. - City of Edmonds issues have been addressed. - See revised drainage design dated October 30, 2000.

Mr. Rob Michel Michel Construction, Inc. 7907 - 212th Street S.W. #102 Edmonds, Washington 98026 Subject: Proposed 9-Unit Condominium at 658 Glen Street Drainage Information As requested by the City of Edmonds during their review of the proposed 9-unit condominium project at 658 Glen Street, the following drainage information is submitted: 1. Existina Site Conditions: The existing site contains a total property of 0.38 acres, which has historically been used as a parking lot, and is covered with 2" of asphalt paving. The soil consists of a sandy silt, grading into a sandy loam. This soi is extremely pervious and drains very well. The existing drainage pattern follows the natural topography of approximately six percent (6%) towards the north. 2. Downstream Conditions: The north and south sides of the City of Edmonds Glen Street are curbed and contain an existing storm water system. Rain water flows into an adequate number of catch basins on either side of Glen Street. From these catch basins, storm water flows through a 12" concrete storm line to the north, through an easement over private property to catch basin C13 8-124d, then east 98.22 feet to manhole MH 8-5d, then northwest 51.60 feet to Shell Creek, then.ce into Puget Sound. This engineer has observed these street inlet catch basins during heavy rains, and has observed no backup or ponding. Obviously, it is important to maintain the access to these inlet catch basins with periodic clean outs. It is understood that the City of Edmonds undertakes such tasks. 3. Proposed Development: This project consists of the construction of a 9-unit condominium project (see project plans). The proposed condominium project will result in 0_24 acres of impervious surface. This project will contain, store and control - release storm water via tight -line into the existing storm system on the south side of Glen Street (see drainage plans dated August 28, 2000). All parking is located under the building, therefore no water quality mitigation is required. 4. DrainaQe Calculations: The attached calculations result in a required storage volume of 699 cubic feet for the proposed 9-unit project.

Some of the questions he had, I could not answer directly, so when you return, could you call him to clarify what was sent to him? His number is 776-2211. He also asked about procedures for requirements for supplying a traffic impact analysis report as a condition of SEPA. I went over this information with Jim Walker and the results are as follows: In the case of similar projects located in the downtown areas, where trip distributions have been established by employment centers, and determined approved by submittal of similar projects; the following shall apply. Mitigation basedon thepeakPMtrips impacting projects identified in the 1995 transportation element and the City of Edmonds 6-year T.LP shall be required to pay the interim $200. 001per peak PM trip impacting these identified areas. The$200.001per peak PM trip was an average of the last two year construction projects assessed to projects within the downtown area. Therefor the submittal of the traffic impact analysis report may be waived and the assessment as agreed by Rob Michelle is 14 peak PM trips @ $200.00 per trip = $2800.00 Cc: Don Fiene, Jim Walker City of Edmonds F- I Is. -t:!-;-4 c c E.

Michel Construction, Inc. 7907 - 212th Street S.W. #102 Edmonds, Washington 98026 Subject: Geotechnical Evaluation "Soils Report" Proposed Nine Unit Condominium Project 658 Glen Street, Edmonds, Washington This engineering report presents the results of a geotechnical evaluation at 658 Glen Street, Edmonds, Washington, with respect to the proposed nine unit condominium project. This evaluation was required due to owner/developer concerns, as well as City of Edmonds requirements. REFERENCES: • Location map • Site plan • Project drainage calculations and drainage plan by D. Bruce, P.E. • Photographs BACKGROUND: The overall property is approximately 0.38 acres, and is covered with two inches (2") of asphalt paving, having historically been used as a parking lot. The overall property contains an approximate six percent (6%) slope, draining north - south. The proposed nine unit condominium project, to be constructed by Michel Construction, Inc., will occupy the majority of the overall property, with access drive to underground parking at the west (see site plan). The surrounding area to this project consists of similar condominium projects to the north and west, and a church building to the south.

Box 55502 - Shoreline, Washington 98155 - (206) 546-9217 - FAX 546-8442 Michel Construction / 658 Glen Street Pagetwo EVALUATION: Visual assessments of the property at 658 Glen 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 condominium project. In order to augment the existing site geotechnical information, soil test pits were dug under this engineer's observation on June 6, 2000. A total of three backhoe soil test pits were dug. (See site plan for locations). All three soil test pits revealed similar subgrade conditions, namely: 0" to 2" Asphalt paving 2" to approx. 5' Relatively clean sands, with occasional gravels 5' to 9' (bottom of test pit) Increasingly dense sandy loam No ground water was observed in any of the test pits. All test pit walls remained vertical and stable. No sloughing or caving occurred. CONCLUSIONS / RECOMMENDATIONS: Based on the findings of this investigation, and experience with similar sites in the area, the property at 658 Glen Street is geotechnically approved for the proposed Michel Construction nine unit condominium project, subject to the following: Standard reinforced continuous and spread footings. Allowable bearing pressure: 2,000 p.s.f. Equivalent fluid pressure of 35 p.c.f. is recommended for any retaining wall design provided drainage zone is inspected and verified by this engineer. For retaining wall design, use friction factor of 0.55 and passive pressure of 350 p.c.f. Temporary shoring in accordance with D. Bruce, P.E. recommendations, utilizing ecology blocks carefully placed under this engineer's inspection are required. This ecology block shoring should be properly embedded in the undisturbed subbase soil and installed at a batter angle of 1 H:6V. Additionally, the shoring blocks should be staggered, as indicated in the elevation view. Michel Construction / 658 Glen Street Page three Geotechnical inspection by this engineer prior to any foundation concrete placement. The proposed structure 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 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 below footings to expose competent native soils. Unless lean concrete is used to 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 bottom of a three-foot wide footing must be at least seven feet wide at the base of the excavation. Footings constructed according to the above recommendations may be designed for an allowable soil bearing pressure of three thousand (3,000) pounds 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 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 one -quarter inch. . Lateral loads due to wind or seismic forces may be resisted by friction between the foundations and the bearing soils, or by passive earth pressure acting on the vertical, embedded portions of the foundations. For the latter 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 resistance to lateral loading: Parameter Design Value Coefficient of Friction 0.55 Passive Earth Pressure 350 p.c.f. Where: Michel Construction / 658 Glen Street Page four (1) p.c.f. is pounds per cubic foot. (2) Passive earth pressure is computed using the equivalent fluid density. We recommend that a safety factor of at least 1.5 be used for design of the foundation's resistance to lateral loading. SLABS -ON -GRADE: Slab -on -grade floors may be supported on undisturbed, competent native soils or on structural fill. The slabs may be supported on the existing soils provided these soils can be recompacted prior to placement of the free -draining sand or gravel underneath the slab. This sand and gravel layer should be a minimum of four (4) inches thick. We also recommend using a vapor barrier such as 6-mil. plastic membrane beneath the slab with minimum overlaps of 12 inches for sealing purposes. PERMANENT FOUNDATION AND RETAINING WALLS: Retaining walls backfilled on one side only should be designed to resist lateral earth pressures imposed by the soils retained by these structures. The following recommended design parameters are for walls less than twelve (12) feet in height which restrain level backfill: Parameter Active Earth Pressure* Passive Earth Pressure Coefficient of Friction Soil Unit Weight Where: Desian Value 35 p.c.f. 350 p.c.f. 0.55 125 p.c.f. (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). 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 Michel Construction / 658 Glen Street Page five 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. 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 (Horizontal: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 Michel Construction / 658 Glen Street Page six 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: No drainage problems were evident with the lot at 658 Glen Street. Surface runoff flows generally northerly into the existing City of Edmonds storm water system, with existing storm water controls. 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. GENERAL EARTHWORK AND STRUCTURAL FILL: The proposed building and pavement areas should be stripped and cleared of all surface vegetation, all organic matter, and other deleterious material. 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. Michel Construction / 658 Glen Street Page seven 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 Beneath footings, slabs or walkways Behind retaining walls Beneath pavements Minimum Relative Compaction 95% 90% 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 the silty, on -site soils are wet, site preparation costs may be higher because of delays due to rains and 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 "pumping" 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. Michel Construction / 658 Glen Street Page eight 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: No drainage problems were evident at 658 Glen Street. Currently surface runoff flows generally northerly. The drainage plan entails total control of storm water runoff by means of containment, a detention vault and controlled orifice release into the existing City of Edmonds drainage system. . CONCRETE: All foundation concrete (footings, stem walls, slabs, any retalning 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: • Soil cuts • Foundation subgrade verification • Retaining wall, or rockery placement • Any fill placement • Subsurface drainage installation SUMMARY: The proposed Michel Construction 9-unit condominium project proposed for 658 Glen Street, 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. STATEMENT OF MINIMAL RISK: The plans and specifications for the proposed nine unit Michel Construction condominium project at 658 Glen Street, Edmonds, Washington, have been reviewed by this engineer and conform to the recommendations of the analysis and report and, Michel Construction / 658 Glen Street Page nine provided that those conditions and recommendations are satisfied during the construction and use, and inspected and verified by this engineer, the area disturbed by construction will be stabilized and remain stable and will not increase the potential for soil movement, and the risk of damage to the proposed development and from the development to adjacent properties from soil instability will be minimal. 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. - If there are any questions, do not hesitate to call. of WAS *$.17405 -Orms- NAL JEXF4RES 12n3/ DMB:vb Dennis M.

Maintain natural vegetation for silt control where possible. 2. Temporary erosion sedimentation control facilities shall be constructed by placing siltabon control filters around swales (natural or manmade) and shall be maintained in a satisfact-Cry condition until such time that land clearing and/or construction of permanent drainage facilities are completed and operational. Facilities shall then be removed and the site restored to the original or final design condition. 3. As construction progresses and expected seasonal conditions dictate, more siltation control facilities may be required to insure complete siltation control of this property. Therefore, during the course of construction, it shall be the obligation of the contractor to address any new conditions that may be created by his activities and to provide additional facilities, as may be needed. 4. ESC Minimum Requirement - Stablization of Exposed Areas. All soils exposed by land disturbing activities shall be staliblized by suitable application of BMPs, including, but not limited to, sod hydroseeding, or other vegetation, plasitic covering, or mulching. All BMPs shall be selected, designed and maintained in accordance with the Manual. The exposed soils shall be stabilized according to an approved timetalbe. (Typically, no soils shall remain exposed for more than two (2) days from October 1 through April 30 and no more than seven (7) days from May 1 thrcugh September 30) 5. Construction Access Route.

Access points shall be stabilized with quarry spalls or cruched rock to mill(rizE: the tracking of sediment onto public roads. If sediment is transported onto a road surface. Lhe roads shall be cleaned thoroughly at the end of each day. Sediment shall be removed from roads by shoveling or sweeping and transported to a controlled sediment desposal area within 24 hours. Street washing shall be allowed only after sediment is removed in this manner. 6. ESC Minimum Requirement - Manintenance. All erosion and sediment control BMPs shall be regullarly inspected and maintained by th owner to ensure continued performance of their intender] function. All maintenance and repair sahll be conducted in accordance with the manual. 7. ESC Minimum Requirement - Cut and Fill Slopes. Cut and fill slopes shall be designed and construc�ted in a manner that will minimize erosion. In addition, slopes shall be stabilized in accordance with ESC Requirement No. 2. 8. ESC Minimum Requirement - Storm Drain Inlet Protection. All storm drain inlets made operable during construction shall be protected so that storm water runoff shall not enter the conveyance system witi-iout first being filtered or otherwise treated to remove sediment. 9. ESC Minimum Requirement - Protection of Adjacent Properties. Adjacent properties.shal be prOtE3cted from sediment deposition by appropriate use of vegetative buffer strips, sediment barriers or filters, dikes or mulching, or by a combination of these measures and other appropriate BMPs.
