Number: 00548900001904 Determination: Study Required Determination #: CA-04-161 Applicant Representative: Steve Waite Owners / Applicants: Carl Zapora / Cheryl Foster CRITICAL AREAS DETERMINATION: STUDY REQUIRED (CA-04-164) During review and inspection of the subject site, it was found that the site may contain or be adjacent to a type of critical area known as a Steep Slope Hazard Area, as defined by Chapter 20.1513 of the Edmonds Community Development Code (ECDC). STUDY REQUIREMENT — STEEP SLOPE HAZARD AREA To determine if a Steep Slope Hazard Area does exist, prior to submission of any development permit, you will be required satisfy the requirements of the Critical Areas Chapter by completing the following Steep Slope Hazard Area Delineation Requirements: A topographic survey must be completed that delineates any Steep Slope Hazard Areas prepared by a Licensed Land Surveyor. [A steep slope hazard areas is defined by the Edmonds Community Development Code as ground that rises at an inclination of 40% or greater'within at least 20 feet of elevation change. In order to delineate a steep slope hazard area, it is necessary to locate the top and toe of the slope. The inclination of the slope is established by averaging the inclination over at least 20 feet of vertical relief. A steep slope hazard area is bordered by a 50-foot-wide buffer measured from both the top and the toe of the steep slope hazard area. Adjacent to the buffer, there is a 15-feet-wide building setback.] In order to complete this Study Requirement, this map must.be submitted to the Planning Division for review and approval. DEVELOPMENT PROPOSALS ON A SITE WITH STEEP SLOPE HAZARD AREAS Development is restricted within the Steep Slope Hazard Area, its buffer, and/or building setback. If development must occur within these areas, the applicant may pursue certain processes provided in the Critical Areas Chapter of the Edmonds Community Development Code. The applicable process depends on the specific development proposal and site but may include one of the following: o For development proposals within the 50-foot buffer, but no closer than 10 feet from the top or toe of the slope, the 50-foot buffer requirement may be reduced to 10 feet if a study is completed by a licensed geologist or geotechnical engineer which clearly demonstrates that the proposed buffer alteration will have no adverse impact upon the site, the public or any private party. This is a process through which development could be allowed as close as 25' from the top or toe of the slope (assuming the buffer may be reduced to 10' — the 15' building setback still applies). o Development proposals closer than 25' from the top or toe of the slope may be allowed through the approval of a Steep Slope Exemption, Critical Areas Variance, or Reasonable Use Exception. These are Land Use Permits that must be obtained through the Planning Division. If you think your specific development proposal may require one of these processes, contact a Planner for more information. PROJECT SPECIFIC CONDITIONAL WAIVERS If the property owner wishes to apply for a specific development permit which they feel would not impact the Critical Areas located on the site, they may submit their proposal to the Planning Department for review. If the Planning Department finds that the proposed development permit will not adversely impact a Critical Area or its buffers, a conditional waiver may be issued on a project by project basis. EXEMPT DEVELOPMENT PROPOSALS Certain development proposals may be exempt from Critical Areas Requirements (ECDC 20.15B.040). If you think that a specific development proposal may be exempt, contact a Planner for more information. NEW REGULATIONS TO BE ADOPTED SOON The City Council has approved a new critical areas ordinance, that should be effective some time after February 1, 2005. The new ordinance differs in the way slopes are defined and the processes that are required for the review of project applications. If you think you will be submitting your development application after the new ordinance becomes effective, you should review the new regulations posted on the City website, www.ci.edmonds.wa.us.

RE: Request for Alternate Design — Air Admittance Valve Dear Ms. Foster, The City is in receipt of your request for alternate design (reference building permit 42005-0326) for installation of an air admittance valve on an upper floor island sink in your home at 1154 Viewland Way in Edmonds. For clarification, our City Building Inspectors have viewed your current field conditions and both inspectors provided you alternate means to provide conventional venting of the island sink. It is the City's contention that conventional venting can be provided at minimal disruption to the joists, heating supply ducts, etc. Regarding your statements concerning the City of Seattle and City of Bellevue; Seattle is the only jurisdiction in the State that has a stand alone building/plumbing/mechanical code. I have no personal knowledge if air admittance valves are out right approved by Seattle code without condition. The City of Bellevue allows air'admittance valves under conditional approval, and requires that applicants demonstrate technical infeasibility. Homeowners must also sign statements acknowledging that the installation is an alternate method. Lastly, I differ in opinion that air admittance valves are `commonly used' and that `these devices are approved in many municipalities.' To my knowledge no jurisdiction in the State allows unconditional substitution of air admittance valves in lieu of conventional venting. Regardless, based on your information that the upper floor island sink will be used minimally, your request to use an air admittance valve is hereby approved with the noted condition below. ➢ Many products are `guaranteed for life' but usually with stipulations such as, `provided properly installed and properly maintained,' etc. Condition of approval of the alternate design request shall include that the plumbing contractor provide.you with written directions as to how to inspect and maintain the air admittance valve for life. Lastly, these directions shall be provided to all future homeowners. Sincerely, Jeannine L. Grat Building Official Cc: State Mechanical • Incorporated August 11,. 1890 • Sister City - Hekinan, Japan • • May 3, 2005 Ms. Jeannine Graf Development Services Department Building Division City of Edmonds 121 5"' Avenue North Edmonds, WA 98020 Re: Alternate Method Request for Building Permit # 2005-0326 , Dear Ms. Graf, RECEIVE:D MAY [005 OFDSSMY EMOND- I am requesting approval for an alternate design to the plumbing vent system in the kitchen island bar sink, as part of the current remodel of my home. Due to space constraints and contention of other building components, an "air admittance" valve rather than a "loop vent" is our proposed solution. Installation of a loop vent, as preferred by the city of Edmonds, is not possible according to our plumbing contractor, general contractor and City of Edmonds inspectors. The following conditions should be noted: • There is a finished living space with a support beam directly below the space at issue. The existing floor joist depth of 10" does not provide enough space to properly construct a loop vent. • There are exiting heating supply ducts in the joist cavities where the loop vent piping would have to be constructed. • Cutting, notching or boring the floor joist for a loop vent would degrade the floor system to an unacceptable structural condition. We were required to notch the floor joist to accommodate the waste line. Further intrusion into the joist would violate the 25% maximum code requirement. Overall, my remodeling project has significant plumbing improvements, all of which have been placed under test, inspected and approved by the City of Edmonds as of 4/28/05, with the exception of this one item. The bar sink in the kitchen island would not experience heavy use and is intended for use while entertaining. Air admittance valves are commonly used in similar situations and were,proposed as the alternative method by our plumbing contractor, State Mechanical. I have enclosed a letter from Greg Platz, owner of State Mechanical . Product specifications and test listings for a couple of air admittance valves are also attached. These devices are code -approved in many municipalities and are guaranteed for life. Thank you very much for your attention to this matter. 673-2295.

(HWA) completed a site reconnaissance and cursory geotechnlcal evaluation of your property where you are proposing to construct a t new exterior deck. This letter report summarizes our observations and provides our conclusions and recommendations. ' AREA ADDRESSED IN THIS CRITICAL AREA REPORT Information provided by Waite Architects (see attached drawing) shows the proposed tnew deck will have approximate dimensions of 11 feet by 20 feet, and will be located across the south end of your house. The new deck will be at the 2"d floor level. One side will be supported on the house, and the other will be supported_ on three, 16-inch square ' by 12-inch thick, concrete pads. A further deck addition is planned for the western side of the house, on the opposite side of the house from the steep slope area. Your existing house is a 2-story, wood -frame, structure supported on cast -in -place concrete spread footings. The house appears to have been constructed in the,1970's. The ' house is oriented in a north -south direction with the building pad partly cut into the toe of an approximately 30 feet high slope. A rockery wall of about 10.feet height supports the cut. The house is located about 9 to 10 feet from the base of the rockery. ' According to the survey information shown on the attached drawing, the average inclination of the slope above the rockery varies from about 107% (about 47 degrees) at ' the north end to about 56% (about 29 degrees) on the south end directly above the planned deck location. Because the slope inclination is greater than 40% and the vertical relief is greater than 10 feet, the slope behind the planned ' 19730 - 64th Avenue.., c,;crP �ni ,www?1iv April 18, 2005 HWA Project No. 2005-000-21 Task 400 ' deck location is classified as a Landslide Hazard Area in terms of Section 23.80.020 B2 of the newly revised Title 23 Critical Areas Regulations of the Edmonds Community Development Code. OBSERVATIONS AND ASSESSMENT OF GEOLOGICAL HAZARDS Brian Hall, P.E., of HWA, made the following observations during site reconnaissance visits on April 6 and 11, 2005: ' • Near the north end of the rockery, the slope inclination above the rockery is locally over -steepened and is experiencing surficial erosion and some surface ' sloughing. The activities of burrowing animals are contributing to this disturbance. On the property to the northeast, where the slope becomes very steep (bluff -like), the remains of a previous shallow slide can be seen. The slide scar has been protected from further erosion by covering with a sheet of plastic. • On the south end of the wall in the vicinity of the planned deck, no evidence of recent erosion or sloughing was observed. The slope is vegetated with ferns, shrubs and some trees. The area near the toe of the slope is mulched with wood mulch. At the top of the slope on the neighboring property, a timber crib ' retaining wall of about 6 to 7 feet height is present. This wall appears stable and no drainage pipes discharge onto the slope. • Where material is exposed on the slope above the planned deck location, it consists of fine to medium sand with some silt and scattered gravel colluvium. No evidence of interlayering of materials was noted. The material forming the slope is interpreted to be Advance Outwash as mapped in the geological map ' "Preliminary Surficial Geological Map of the Edmonds East and Edmonds West Quadrangle, Snohomish and King Counties, Washington"; dated 1975 and prepared by Mackey Smith. It should be noted that the more recent geological map "Geological Map of the Edmonds East and Part of the Edmonds West Quadrangles,- Washington"; dated 1983 and prepared by James P. Minard, indicates the area is underlain by Vashon Till. It is possible that the upper part of ' the slope is blanketed by till, but no direct visual evidence of till was apparent. • It was not possible to reliably determine the stability of the rockery because no ' information is available on the thickness and internal configuration of the rockery, or nature of the undisturbed native material retained by the wall. However, no evidence of previous instability, or evidence of potential future instability in the ' form of bulging or, overhanging sections, was observed. Moreover, the requisite four to five man size rocks has been used for the construction of the lower ' courses. The only areas of minor distress noted were two or three areas, where ' Foster-Zapora Deck Geot. Ass.(new code) 2 HWA GEOSCIENCES INC. 1 ' April 18, 2005 HWA Project No. 2005-000-21 Task 400 individual rocks in the face had cracked. Crushed rock was visible behind the face rocks, and was,likely used as a drainage course. • The slope material and the material at the base of the wall were probed using a t/z- inch diameter, pointed, steel rod. Under body weight, the probe typically penetrated the soil on the slope to an average depth of about 18 to 24 inches, and ' about 3 to 4 inches at the toe of the wall. It was concluded from this probing that the loose material on the slope face was less than 36 inches thick, and the soil between the rockery and the house was medium dense to dense, and capable of supporting pad footings. ' • At the time of the visits, the area between the house and the rockery was wet, and two zones of surface wetness were noted on the face of the wall. It was concluded that the wet areas reflected poor drainage of surface runoff because the ' visits were undertaken after periods of rain, there was an absence of vegetation associated with persistently wet ground conditions, and the ground at the toe of the rockery is flat. The presence of burrowing animals in the slope directly above the rockery is indicative of dry slope conditions. The wetness on the face of the wall does not constitute significant ground water seepage and rather reflects drainage of slope runoff through the wall. 1 • Wet conditions are present at the extreme north end of the property beyond the ' north end of the rockery. Marsh vegetation such as skunk cabbage is growing in this area. This seepage appears to originate from drains located on the adjacent property. ANALYSIS OF PROPOSAL We consider that the landslide hazard threat in the vicinity of the proposed new deck is low for the following reasons: • The slope consists of Advance Outwash (possibly overlain by glacial till), which are capable of remaining stable at very steep slopes. . ' • There is no fill on the slope. ' • In' the vicinity of the planned new deck, there is no evidence of impermeable soils interbedded with granular soils, no significant ground water seepage was noted (the two patches of wetness on the wall relate to surface runoff), and there is no evidence of previous landsliding or existing landslide deposits. 11 Foster-Zapora Deck Geot. Ass.(new code) 3 HWA GEOSCIENCES INC. ' April 18, 2005 HWA Project No. 2005-000-21 Task 400 ' • The thickness of loose surface material was probed and found to be less than 36 inches thick (averages about 18 to 24 inches thick). Based on our assessment, we consider that the planned deck construction will not impact the slope and will not increase the landslide hazard threat beyond pre- development.conditions, and will not adversely impact other critical areas. If the ' deck is. located and designed as recommended in the following section, we certify per the intent of Section 23.80.060 A4 that the deck will be safe for the anticipated conditions. RECOMMENDATIONS The pad footings for the deck should be located at least 10 feet from the base of the high section of the rockery, because a rockery is not an engineered structure, ' and because individual rocks from the top course can be dislodged. • The allowable soil bearing pressure is 2,000 psf. The planned 16-inch square by ' 12 inches thick pad footings will likely be suitable provided this allowable bearing pressure is not exceeded. The base of the pads should be located at least ' 18 inches below ground surface for frost protection. • The pad footing excavations should made using hand equipment and no ' excavations should be undertaken within .10 feet of the base of the high portion of the rockery. Disturbed bearing soil in the base of the excavation should be ' compacted to a dense/hard condition by hand tamping prior to concrete placement. Similar foundation recommendations apply to the pad footings for the deck on the western side of the house. ' LIMITATIONS Our scope of work included a visual assessment and review of existing geotechnical information, augmented by shallow hand probings. Deep borings or other intrusive testing on the subject property may have indicated other conditions that are not apparent ' in a visual inspection. The interpretations in this report should not be construed as our warranty of the subsurface conditions. Experience has shown that soil and ground water ' conditions can vary significantly over small distances.
