File No. S-02-33 Page 2 of 6 I. INTRODUCTION A. Application 1. Mlicant: Michaelson Corporation (see Attachment 2) 2. Site Location: 9530 Edmonds Way (see Attachment 1) 3. Request: To divide two lots with a combined area of approximately 36,375 square feet into 4 lots in a Single -Family Residential RS-8 zone (see Attachment 3). 4. Review Process: Following the Comment Period, Planning Staff makes an administrative decision. 5. Major Issues: a. Compliance with Edmonds Community Development Code (ECDC) Section 16.20.030, site development standards for the RS-12 zone. b. Compliance with Edmonds Community Development Code (ECDC) Section 20.75, subdivision requirements. c. Compliance with Edmonds Community Development Code (ECDC) Title 18, public works requirements d. Compliance with Edmonds Community Development Code (ECDC) Section 20.95, staff review requirements. B. Decision Based upon the Findings of Fact and Conclusions, Attachments and Exhibits submitted with the application and during the comment period, the following is the decision of the City of Edmonds Planning Division: The Subdivision is APPROVED with the following conditions: 1. Prior to recording the applicant must complete the following requirements: a) Complete the Engineering Division conditions listed "Required prior to Recording" on Attachment 4. b) Any vehicular easement, or addition to Tract X (the private road), to allow for turnaround must be subtracted from the lot size. The lot sizes may not be reduced below the required 8,000 square foot minimum c) If setbacks are to be included in the plat, add to the face of the Plat "Setbacks shown are for reference only and vest no right." Note that setbacks according to current regulations are as given in Section II.A. Lf, which no street setback required from the private road. d) Add to the face of the Plat "Conditions of approval must be met and can be found in the final approval for the short subdivision located in File S-02-33." e) Include on the plat all required information, including owner's certification, hold harmless agreement, and staffs approval block. f) State on the face of the plat who will own Tract X, the private road, and provide a maintenance agreement on the short plat. g) Grading more than 500 cubic yards has not been considered with this application. If more than 500 cubic yards will be required to construct subdivision improvements, a SEPA review will be required. h) As required in the Geotechnical Engineering Study performed by Liu & Associates dated December 20, 2001, (see Attachment 5) setback for structures on proposed lots 3 and 4 shall be at least 30 feet from the toe of the steep slope lying over the adjacent properties or 15 feet from the south boundary of the site, which ever is greater. S-02-33.doc / April 29, 2002 / Staff Report II. Michaelson Corp. File No. S-02-33 Page 3 of 6 i) Due to the trees and other shrubs ability to minimize some of the geologic hazard risks as stated in the geotechnical report, as well as their importance to wildlife, the applicants are encouraged to preserve healthy trees and native vegetation where possible. j) Make sure all documents to be recorded meet the Snohomish County Auditor's requirements for recording. k) Submit copies of the documents to be recorded for the Planning Division and Engineering Division's approval. Once approved, the applicant must record the documents with Snohomish County Auditor's office. 1) Submit an updated copy of the title report (short plat certificate) with the documents proposed to be recorded. m) Anyone signing for Gaston Enterprises LLC should have documentation that they are authorized to sign for the corporation. 2. Submit two copies of the recorded documents with the recording number marked on them to the Planning Division. The City will not consider the subdivision to have been recorded until this is done. 3. Complete the Engineering Division conditions listed "Required with Building Permit" on Attachment 4. FINDINGS OF FACT AND CONCLUSIONS A. Analysis of Design: 1. Lot sizes and dimensions: a) Proposed number of lots: 4 b) Required Lot Area (RS-8 zone): 8,000 square feet c) Proposed Lot sizes: Net sq. ft Gross sq. ft Lot 1 8,055 8,055 Lot 2 8,006 8,006 Lot 3 8,079 8,079 Lot 4 8,010 8,010 d) Required Lot Width (RS-8 zone): 70 feet e) Proposed Lot Width: Meets Width Requirement? Lot 1 Yes Lot 2 Yes Lot 3 Yes Lot 4 Yes f) Setbacks: Setbacks should be as follows: Lot 1: Street Setback (25 feet): Side Setbacks (7.5 feet): Rear Setback (15 feet): Lot 2: Side Setbacks (7.5 feet): Lot 2: Side Setbacks (7.5 feet): Lot 2: Side Setbacks (7.5 feet): From the northwest property line From the east and west property lines From the south property line From all property lines From all property lines From all property lines S-02-33.doc / April 29, 2002 / Staff Report Michaelson Corp. File No. S-02-33 Page 4 of 6 g) Corner Lots: None of the lots are considered comer lots. h) Flag lot determination: Lots 2, 3 and 4 are considered flag lots. 2. Lot arrangement to topography: Satisfactory. Behind this site is a steep slope. The toe of the slope is shown on the preliminary plat map, and it is wholly on the adjacent lots to the south. The subject property has a much gentler slope. 3. Lot Coverage of Existing Buildings on Proposed Lots: a) 35% maximum lot coverage is allowed. b) The lot coverage of the existing buildings on all proposed lots is 0 %. 4. Zoning: The subject property is zoned RS-8 (single-family residential with a minimum 8,000 square foot lot area). All lots meet the minimum lot width and lot size. 5. Consistent with the purposes of the Zoning Ordinance? Yes. B. Conformance to Comprehensive Plan: 1. Conforms to the policies of the Comprehensive Plan? Yes. The Comprehensive Plan encourages flexibility in development standards to encourage infill development when it will be consistent with the character of the neighborhood. The proposed development would result in four lots where there are currently two. C. Environmental Assessment: 1. Is this site identified on the City's Environmentally Sensitive Areas Map? No. 2. Is an Environmental Checklist Required for this application? No. D. Critical Areas Review: 1. Critical Areas Review number: CA-1998-193 and CA-1998-194 2. Results of Critical Areas Review: A critical areas study was required for steep slopes. A survey has been submitted which shows the toe of the slope on the adjacent property (see Attachment 3) and a geotechnical report and additional letter (see Attachment 5) have advised that the buffer can be reduced. Page 12 of the Liu & Associates Geotechnical Engineering Study for 4-Lot Short Plat, dated December 20, 2001, states "Due to the competent soils and a low potential of deep-seated slides at the site, it is our opinion that the buildings to be constructed on the upslope southern portion of the site be setback at least 30 feet from the toe of the steep slope lying over the adjacent properties or 15 feet from the south boundary of the site, which ever is greater." The geotechnical report also points out the importance of maintaining vegetation cover on unpaved ground (see Attachment 5, page 6). This site contains many mature trees, some of which are healthy, others of which have split trunks or are near the end of their lives. Unfortunately, some of the healthy trees are within the logical building pad for new development. Due to the trees and other shrubs ability to minimize some of the geologic hazard risks as stated in the geotechnical report, as well as their importance to wildlife, the applicants are encouraged to preserve healthy trees and native vegetation where possible. 5-02-33.doc / April 29, 2002 / Staff Report Michaelson Corp. File No. S-02-33 Page 5 of 6 E. Required Improvements and Dedications: 1. Engineering, drainage and street dedications: See City Engineer's Report (Attachment 4). F. Public Comments: One public comment was received (see Attachment 6). Because it discusses the intersection at 96's and 228h and states that the hill has already been graded and logged (which has not occurred on the subject property), staff believes they are referring to the plat by Michel Construction at 9601 Edmonds Way. The comment period for that application, file P-2001-22 has already expired and construction on the subdivision is under way. III. RECONSIDERATIONS AND APPEALS The following is a summary of the deadlines and procedures for filing reconsiderations and appeals. Any person wishing to file or respond to a recommendation or appeal should contact the Planning Department for further procedural information. A. Request for Reconsideration Section 20.095.050.B.2 allows for planning staff to reconsider their decision if a written request is filed within ten (10) working days of the posting of the notice required by this section. The reconsideration request must cite specific references to the findings and/or the criteria contained in the ordinances governing the type of application being reviewed. B. Appeals Section 20.095.050.B.3 describes how appeals of a Staff decision shall be made. The appeal shall be made in writing, and shall include the decision being appealed along with the name of the project and the date of the decision, the name of the individual or group appealing the decision, their interest in the matter, and reasons why the appellant believes the decision to be wrong. The appeal must be filed with the Community Development Director within fourteen { 14) calendar days after the date of the decision being appealed. C. Time Limits for Reconsideration and Appeals The time limits for Reconsiderations and Appeals run concurrently. If a request for a reconsideration is filed before the time limit for filing an appeal has expired, the time "clock" for filing an appeal is stopped until a decision on the reconsideration request is completed. Once the staff has issued his/her decision on the reconsideration request, the time clock for filing an appeal continued from the point it was stopped. For example, if a request is filed on day 5 of the appeal period, an individual would have 9 more days in which to file an appeal after the staff issues their decision on the reconsideration request. IV. LAPSE OF APPROVAL Section 20.075.100 states, "Approval of a preliminary plat or preliminary short plat shall expire and have no further validity at the end of five years, unless the applicant has acquired final plat or final short plat approval within the five-year period." V. NOTICE TO COUNTY ASSESSOR The property owner may as a result of the decision rendered by the staff request a change in the valuation of the property by the Snohomish County Assessor's Office.

Conventional footing foundations placed into undisturbed Glacial Drift deposit of gray, dense, silty sand with gravel and occasional cobble or Advance Outwash deposit of gray, dense, gravelly sand with occasional cobble may be used for supporting the residential buildings to be constructed on the building lots. Structural fill, if required for grading the building lots and roadways, should be placed on the above -described Glacial Drift or Advance Outwash deposits following the stripping of the surficial unsuitable soils. GEOLOGIC HAZARDS Landslide Hazard Due to the gentle to moderate slopes throughout the site and the very competent and stable Glacial Orin and Advance Outwash deposits underlying the site at , shallow depths, the risk for deep-seated landslides to occur on the site should be minimal. There is a possibility that shallow, skin -type, mudslides may occur in the surficial topsoil and the light -brown, medium -dense fine sand on the steeper upslope area in the southern portion of the site when these soils are overly saturated. To tninimie such risks, the vegetation cover on unpaved ground should be maintained and uncontrolled discharge of concentrated stormwater onto the ground should not be allowed within the site. Erosion Hazard The surficial topsoil, the light -brown fine sand and the Advance Outwash are of low to moderate resistance against erosion, while the underlying Glacial Drift deposit has relative high resistance against erosion. The erosion potential of the site during construction can be minimized by placing a layer of crushed rock over areas of frequent construction traffic and by installing a curtain drain along the upslope southern boundary and the southern half of the eastern boundary of the site to intercept near -surface groundwater flow to drain the water off the site. Unpaved finished ground within the site should be landscaped and planted with grass or shrubs to minimize soil erosion potential. LIU & ASSOCIATES, INC. I I I I I I k December 20, 2001 4-Lot Short Plat L&A Job No. 2001 Page 11 ROADWAYS Roadway pavement design for the proposed development is critically related to the conditions of the underlying subgrade. We recommend that the subgrade soils within the roadway be treated and prepared as described in the SITE PREPARATION AND GENERAL EARTHWORK section of this report. Prior to placing base material, the subgrade soils should be compacted to a non -yielding state with a vibratory roller compactor and proof -rolled with a piece of heavy construction equipment, such as a fully -loaded dump truck. Any areas with excessive weaving or deflection should be over -excavated and re -compacted or replaced with a structural fill or crushed rock placed and compacted in accordance with the recommendations provided in the STRUCTURAL FELL section of this report. We recommend that a 6-inch-thick, compacted, crushed rock base (CRB), consisting of 5/8-inch- minus crushed rock, be used for the roadways. Such crushed rock base will not be required if the roadways are based on subgrade soils cutting into undisturbed, proof -rolled Glacial Drift and Advance Outwash deposits or on structural fill constructed over Glacial Drift and Advance Outwash. For the pavements of the roadway, the crushed rock or subgrade base should be topped with 3-inch asphalt treated base (ATD) topped by 2-inch-thick Class 8 asphalt concrete (AC). BUILDING SET19ACKS The purpose of building setback from the top or toe of a slope is to establish a buffer zone between a structure and a slope, such that if a slope failure should occur, the damages to the structure can be minimized. Similarly, if a building is to be constructed on a slope, the building should have adequate setback from an overly steep portion of the slope. In general, the .greater the setback, the lower the risk for the structure to sustain damages from a slope failure. Municipalities also use buffer and setback to minimize potential disturbance to critical or sensitive areas, in addition to mitigate damages to proposed developments. LIU & ASSOCIATES, INC. December 20, 2001 4-Lot Short Plat L&A Job No. 2001 Page 12 The slope of the site is generally gentle to moderate, varying mostly from less than 6% to about 17% gradient, except near the southeast corner of the site where the slope steepens locally to about 36%. The variation of the slope within the site is generally gradual. The only noticeable break in the slope is at the toe of the steep slope lies within the adjacent properties to the south of the subject site. The site is underlain by dense to very dense Glacial Drift and Advance Outwash deposits of high shear strength. Due to the competent soils and a low potential of deep-seated slides at the site, it is our opinion that the buildings to be constructed on the upslope southern portion of the site be setback at least 30 feet from the toe of the steep slope lying over the adjacent properties or 15 feet from the south boundary of the site, which ever is greater. To enhance the stability of the buildings to be constructed on the southern lots, the foundations of these buildings should be constructed at least one foot into the underlying Glacial Drift or Advance Outwash deposit. The foundation walls along the south side of the buildings should be extended upward at least 4 feet above the finish grade to catch mudslide debris in case shallow skin -type mudflow should occur on the slope above these buildings. ]WELDING FOUNDATIONS Conventional footing foundations may be used for supporting the residential buildings to be constructed on the building lots. The footing foundations should be placed on or into the underlying, undisturbed, gray, dense, Glacial Drift or Advance Outwash deposits. Water should not be allowed to accumulate in excavated footing trenches. Disturbed soils in footing trenches should be completely removed or thoroughly re -compacted prior to pouring concrete for the footings. If the above recommendations are followed, our recommended design criteria for footing foundations are as follows: LIU dot ASSOCIATES, INC. L•>A ASSOCIATES 466 6 r LIU & ASSQCIA.TES, INC.
