Graf, Building Offici RE: Plan Check 9BLD2008-0376 Project: Ray SFR Project Address: 15625 75'� Place West During review of the above noted application, it was found that the following information, corrections, or clarifications are needed. It is permissible to red line the plans on file at City Hall to expedite the re -check (if you choose to red -line contact the Permit Coordinator, Marie Harrison, in advance to coordinate plan sets). If sheets are to be revised only resubmit sheets that have changes. All changes should be hi -lighted or bubbled in order to expedite re -check. 1) The submittal appears to have the following minimum submittal items missing: a) Land Clearing and Tree Cutting Plan (4 copies). It is permissible to make a notation on the plot plan that no clearing will take place and no significant trees (greater than 6 inches in diameter measured at 4 feet above grade) exist on site. b) Grading Plan (4 copies) with grading calculations. Grading in excess of 500cyds requires a SEPA checklist. c) Temporary Shoring plan (4 copies) with appropriate shoring details. d) Traffic Analysis (3 copies) c) Affidavit of Site Posting (signed by Applicant/Owner) 2) On the Plot Plan please correct the following: a) The reduced plot plan must match the large scale plot plan b) Water meter shown on private property; water meters are set in City right-of-way (regardless of whether or not a formal street dedication has been made). The property line should be shown to the east of the water meter and setbacks indicated from the property line accordingly. The City Engineering Division will determine whether or not a formal street dedication is required; regardless setbacks must be taken from the future dedication. c) Indicate the existing garage is to be demolished d) Include the modular block wall on the north side of the driveway (as shown on the civil plans) e) See #4 below and add on plot plan as needed. f) Height calcs as shown on sheet A14. g) Add fireplace extension on south side of residence, indicate size of encroachment and distance to property Tine. 3) On Sheet A7 detail A2 add the most western stair retaining wall; clearly indicate the wall height above existing grade. 4) The driveway slope is proposed at 13.3%. It appears a retaining wall is needed on the south side of the driveway to retain the slope. This wall would support a surcharge and must be designed accordingly; provide wall detail and supporting calculations (3 copies plan, 2 copies talcs). 5) Add note that kitchen sink will either vent through the roof or with a loop vent as permitted by UPC 909.0. 6) Provide manufacture specs for the aluminum guard rail. 7) The kitchen fan is not permitted to be used as a whole house fan and the Energy worksheet has been changed to laundry room if the designer chooses another location {such as bathroom) please redline the worksheets on file at the City and plans. 8) Show required crawlspace venting locations, caution on location of required holddowns. Holddowns take precedent over vent locations. 9) Special inspections are required for the following special inspections. Complete the enclosed special inspection agreement signed by the owner, the general contractor and the special inspector and submit to the City for approval prior to permit issuance. • Start of Work letter from Geotech • General Site Monitoring • Temporary Shoring • Site Preparation, Excavation, Grading • Structural Fill & Compaction, Proof -Rolling • Soil Bearing Verification • Retaining Wall/Block Wall placement, Backfill and Drainage • Subsurface Drainage Installation, Perimeter Footings • Temporary and Permanent Erosion Control • Final Report from Geotech of Record 10) Respond in writing to attached structural plan review comments.

BLD20080376 RAY SFR —15625 75"x` PLACE WEST EDMONDS, WASHINGTON This technical memorandum provides our geotechnical peer review of portions of the permit package submitted to the City of Edmonds (City) for the proposed referenced development within the Earth Subsidence and Landslide Hazard Area (ESLHA) of North Edmonds. The purpose of this geotechnical peer review was to review portions of the submittal package and assess its compliance with City development and building permit requirements as contained in Edmonds Community Development Code (ECDC) Chapters 19.10 and 23.80. This geotechnical peer review was accomplished in accordance with Task Order No. 08-10 of Landau Associates' On -Call Geotechnical Engineering Services Agreement with the City. We have received the following information forwarded by the City for review: • Revised Subsurface Exploration, Geologic Hazard, and Geotechnical Engineering Study, Proposed Ray Residence Re -Construction, 15625 75`h Place West, Edmonds, WA, Parcel No. 00513100002402,. prepared for Mr. Kyle Ray by Associated Earth Sciences, Inc., dated January 10, 2008. • Geotechnical Hazard Identification /Declaration and Mitigation Statement of Risk, Proposed Ray Residence Reconstruction, 15625 Place West, Edmonds, WA, Parcel No. 00513100002402, prepared for Kyle and Juliann Ray by Associated Earth Sciences, Inc., dated April 25, 2008. • Civil Engineering Drawings (2 sheets, including Grading and TESC Plan, and Road and Drainage Plan), prepared by Donna L.

The following sections provide our review comments. GEOTECHNICAL REPORT The geotechnical report prepared by Associated Earth Sciences, Inc. (AESI) dated January 10, 2008 provides a reasonably comprehensive evaluation and discussion of site conditions and risks, and provides geotechnical recommendations for design. We concur with the approach of using a rigid, grid -type foundation underlain by compacted structural fill in order to mitigate the potential for structural damage due to differential ground displacements. Design of the lower portion of the east wall of the structure as a debris catchment wall is also prudent. The report mentions the stabilizing influence of the Burlington Northern Railroad tracks and that "To our knowledge, no evidence of recent movement of the deep-seated slide planes has been documented." The report by Dames and Moore (1968) that is referenced in the AESI report documents large scale landslides in 1947 and 1955-56. These large scale landslides are also mentioned in Landau Associates (2007) summary report. We note that one of the two large-scale landslide features from 1955-56 mapped in the Dames and Moore report appears to encompass the Ray property. The City's Geotechnical Report Guidelines requires that the Geotechnical Consultant provide at least one cross section extending across the site drawn perpendicular to the contours showing soil and groundwater conditions in relation to the proposed site grading and structures. The AESI report does not include a cross section. We recommend that a cross section be provided. We note that the Vicinity Map included in the submittal package references the report by Hemphill Associates (1990) on the property immediately to the south of the Ray property. However, this report is not referenced in the AESI report. If AESI has not already done so, the Hemphill report on the adjacent property should be reviewed and considered relative to the conditions and design approach on the Ray property. 6116108 1\Edmdatalprojects167411511R1e Rm1R\GeotPeerReview-Draft_tmdoc LANDAU AssOCIATES 2 Geotechnical monitoring and inspection of earthwork by the Geotechnical Engineer of Record is required, including placement and compaction of structural fill, foundation bearing, temporary shoring, retaining walls, and retaining wall backfill and drainage. The plans should note this requirement. CIVIL PLANS Landscaping plans for the area surrounding the house were not included in the plans provided for our review. We recommend that basic landscaping plans for the property be provided that confirm that the steep slope areas on the east side of the property will remain protected by native vegetation and that additional cuts, fills, or retaining walls are not planned as a part of landscaping improvements to the property. Inspection, maintenance, and regular reporting of TESC measures by the Geotechnical Engineer of Record are required [see the City of Edmonds Earth Subsidence and Landslide Hazard Area Temporary Erosion and Sediment Control (TESC) Requirements]. The pre -construction meeting needs to include the Geotechnical Engineer of Record [see City of Edmonds Earth Subsidence and Landslide Hazard Area Temporary Erosion and Sediment Control (TESC) Requirements]. These requirements should be noted on the Grading and TESC sheet and the owner or lead design professional should arrange for these services with the Geotechnical Engineer of Record. The City requires that earthwork during the winter season between October I and April 30 be restricted. We recommend that the TESC and Grading plans specifically indicate that earthwork is restricted between October I and April 30 and any earthwork in this time period requires approval from both the Geotechnical Engineer of Record and the City Building Official. REQUIRED STATEMENTS AND DECLARATIONS We reviewed the submittal package to confirm that the statements and declarations as required by the City for development within the Earth Subsidence and Landslide Hazard Area have been appropriately addressed. • AESI has provided a Geotechnical Hazard Identification/Declaration and Mitigation Statement of Risk letter dated April 25, 2008. • Statements from other design professionals were not included in the package that we were provided to review. We assume that the City is confirming that the other required statements and declarations have been submitted and are in order. 6118108 \\EdmdataVrojects10741151TAa Rm1R\GeotPeerRaview-Draft tm.doc i_P.NDAU AsSOCIATES 3 This technical memorandum has been prepared for use by the City of Edmonds in evaluating the adequacy of permit submittal documents related to the proposed Ray single family residence at 15625 75"' Place West. The focus of this review was the geotechnical aspects of the application. The purpose of the review was to assess the adequacy of the application documents for compliance with City requirements contained in ECDC 23.80 and ECDC 19.10 and conformance with conventionally accepted geotechnical engineering practices. This geotechnical peer review by Landau Associates does not lessen the requirements for the applicant's geotechnical consultant and other design professionals to prepare an appropriate design for the site conditions. We appreciate this opportunity to be of service to the City. Please contact us if you have any questions or if we may be of further service.
