In my opinion, the construction of a fence along the major slope -break will cause no adverse effect on the stability of the slope. Similarly, a three -foot wide concrete walkway along the back of the house and a roughly 10- foot by 10 -foot patio and concrete steps against the rear of the house will have no detrimental effect to the steep slope.

Mullet, Mayor Department of Community Development Steve Lancaster, Director As you know, the Tukwila Short Subdivision Committee granted preliminary approval to the above - referenced short plat application on May 20, 2005. Per TMC 17.12.040, upon written request by the applicant prior to the expiration date, "the Short Subdivision Committee may grant one extension of not more than one year." The Short Subdivision Committee has reviewed your May 19, 2006, letter requesting an extension of that expiration date. This letter is to acknowledge our approval of your request and to formally extend the deadline from May 20, 2006 to May 20, 2007. However there is no record of any inspections on the construction permit. Please note that the preliminary short plat approval will expire on May 20, 2007, if it is not recorded by then. If you have any questions, please contact Minnie Dhaliwal at 206 -431 -3685.

We were not able to obtain a construction permit until fall of last year. After the permit was obtained, we had difficulty securing a contractor as all were very busy during the fall months as it was nearing the end of the construction season. Then, we had an unusually wet winter. This site is prone to high ground water and drainage runoff from off -site sources. Our construction plans account for that runoff, but it is not practical to make the necessary connections and transitions while the drainage is running at capacity, during the winter. Additionally, one of the first items that need to be constructed is the drainage vault. This will required excavating a 15' deep, large hole approx. 25' away from the top of the slope. With the steep slopes, the high groundwater and the necessity for deep excavation, it would not have been advised to begin construction during the extremely wet weather. Due to these circumstances, we cannot begin construction until later this spring. We need to be past the wet weather season. As such, we request that the preliminary short plat approval be renewed or extended to allow construction this summer and final short plat approval this fall. Thank you for your attention.

The project site consists of a 3.13 -acre parcel located at 17083 53` Avenue South, Tukwila, Washington. There is an existing house on the east side of the property that will remain. The purpose of our work is to offer an opinion as to the adequacy of the geotechnical engineering report submitted with the permit application. The geotechnical report for this project was prepared by Bergquist Engineering Services and is dated March 8, 2005. The report presents the results of eight test pit explorations and geotechnical recommendations for site development. The test pit explorations extended to depths of 5.5 to 10 feet and encountered fill and topsoil underlain by medium dense to dense native soils. The report provided descriptions of the site geology, surface conditions, and subsurface soil and groundwater conditions. It provided opinions and recommendations regarding site development, foundation design, earth pressures, drainage, slope stability, buffers and setbacks, and other typical geotechnical design issues. Based on our site observations, we generally concur with the opinions and recommendations provided in the Bergquist Engineering Services report. In our opinion, the geotechnical report prepared for this project would meet the generally accepted standards of practice in this area and meets the standards of Tukwila Municipal Code 18.45.080E. 21 -1- 20314 -001 50 y ews 1954 -2004 Ms. Jill Mosqueda City of Tukwila April 15, 2005 Page 2 We appreciate the opportunity to be of service.

Dear Parties of Record: City of Tukwila Department of Community Development Steve Lancaster, Director This is in response to the written comments and concerns we received regarding the proposed eight -lot short plat at the above referenced location. You had provided some information regarding existing drainage conditions in the area and had asked for some additional analyses of how the proposed short plat would impact the existing drainage conditions. The city provided your comments to the applicant and had their engineer assess the conditions and provide a response addressing your concerns. The applicant's response is attached to this letter. The applicant is proposing to replace the existing 12" drainage pipe with a new conveyance system for the off -site drainage consisting of several catch basins and a 12" pipe. A 10 feet wide public drainage easement is proposed for this pipe. The City is in the process of reviewing their geotechnical report and will be issuing State Environmental Policy Act (SEPA) determination within the next few weeks. The short plat preliminary approval is will be issued after the SEPA determination. You will receive a copy of any decisions issued by the City.

Therefore, as requested, I evaluated the stability of the slope south of Lot 7 along the cross section identified as C -C" on the attached Site Plan, page Al . The engineering properties presented below were determined from the results of Test Pits 7 and 8 and used in the stability analysis. The stability of the slope was estimated during static conditions (see page A2) and during dynamic (seismic) loads (see page A3) of 0.3g horizontal and foundation loads of 2000 psf located 35 feet from the crest of the slope. The cross section of the slope and the results of the stability analysis are presented on pages A2 and A3 of this report. During static conditions, the minimum safety factor is estimated to be 2.428. During seismic conditions, the minimum safety factor is estimated to be 1.486. Accordingly, for Lots 7 and 8 only, as shown on page Al, we recommend that a buffer of 25 feet from the crest of the slope and a building setback of 10 feet from the buffer be established. Construction and disturbance of vegetation within the 25 -foot buffer shall not be GEOTECHNICAL ENGINEERING AND CONSTRUCTION INSPECTION Proposed Pieper Short Subdivision BES Project Number. 200415, Report 2, Addendum 1 March 15, 2005 Tukwila, Washington permitted.

The letters are from John Discher (12/21/04) and Earl Gibson (12/22/04). The letters discuss several aspects of the proposed short plat. In this submittal, I would like to discuss the drainage issues that were raised in the letters. RECEIVED MAR 16 2005 COMMUNITY DEVELOPMENT Both of the parties own property that is northwest of the site and front along 51st Ave. S. These properties are within a drainage basin that is upstream from the Pieper property. This upstream drainage basin is defined by a low area along 51st Ave. S. that is between S. 170th St. and S. 172nd Pl. All of the upstream drainage west of 51 Ave. S. is collected by a conveyance system along the west side of this street and piped to this low point and to the east across 51st Ave. S. There appear to be several ditches /culverts that convey this drainage to the east towards 53r" Ave. S. One of these off -site conveyance systems routes a portion of this off -site drainage to a low area that is north of the Pieper property, There is an existing perforated drain pipe that is connected to this low depression and connects to an existing 12" pipe that runs through the Pieper property and the adjacent smaller lot. This pipe has been added to the preliminary drainage plan that is attached. The Pieper short plat w ill need to abandon this existing 12" drainage pipe because its outlet is in the area of the proposed drainage vault. A new conveyance system will be constructed for the off -site drainage that will consist of several catch basins and 12" pipe. A 10' wide public drainage easement will be provided for this pipe. It will be connected to the catch basin at the outlet from the vault and prior to the "driscopipe" outfall. I have been told by the owner (Mr. Pieper) that the small depression has never filled with water, even during major storms. The existing 12" pipe that runs through the Pieper property carries water during periods of rainfall. Groundwater flow was observed at the discharge to this pipe just recently. In summary, the Pieper short plat will not affect the up- stream drainage system. The existing conveyance pipe that runs through the Pieper property and carries a portion of the up- stream drainage will be abandoned and replaced with a new pipe & CB network. This will allow the drainage to perform as it does now. The outlet will be enhanced because it will no longer discharge at the top of the slopes; but will be connected to the proposed "driscopipe" outfall system. Please feel free to call me with any questions or concerns. Sincerely, 9 0J‘mg - ti9 - 9°' - ueA ) James Jaeger, P.E.

The field and laboratory data were then evaluated by the geotechnical engineer relative to the proposed construction. The engineering recommendations and advice presented in this report have been made in accordance with generally accepted geotechnical- engineering practices in the area. 4. SITE CHARACTERIZATION The information presented in this section was gathered by BES personnel for geotechnical engineering purposes only. This site characterization was not intended to address the presence or likelihood of contamination on or around the site. Specialized methods and procedures, which were not a part of this scope of services, are required for an adequate environmental site assessment. 4.1 Site Classification According to P /ate 1 Generalized Geologic Map of Seattle and Suburban Areas by Galster, R. W., and Laprde, W.T., 1991, the site soils are comprised of Vashon Stade till and Vashon recessional sand and gravel. Based on the soil classification and density as determined by the test pits, the soils at this site are not susceptible to liquefaction. 4.2 Surface Most of the 3.13- acre site is relatively flat and level but the property incorporates a north- northeast to south - southwest trending steep slope that roughly parallels Interstate 5 along the east and southeast ..� side of the property. The steep slopes decline from approximate crest elevation of 240 feet to approximate elevation 160 feet at slopes ranging from 60 percent (31° from horizontal) to about 900 percent (88° from horizontal). The slopes are covered with a moderately dense stand of predominantly large leaf maple trees. Several of the trees along the northernmost portion of the property are bowed slightly, which indicates that there has been some creeping of the slope. The paved walk southeast of the existing Pieper residence are cracked and slightly offset down suggesting that the slope has been creeping over time. South of the existing house, there are some shallow earth fissures about 25 feet from and parallel to the major slope - break. Mr. Pieper reported Proposed Subdivision (Pieper Short Plat) March 8, 2005 Tukwila, Washington BES Project Number 200415, -Report 2 Bergquist Engineering Services Page 3 of 13 Proposed Subdivision (Pieper Short Plat) March 8, 2005 Tukwila, Washington BES Project Number 200415, -Report 2 that years ago, he had placed fill on the surface of the site, south of the existing house. According to .. Proposed Subdivision (Pieper Short Plat) March 8, 2005 Tukwila, Washington BES Project Number 200415, -Report 2 exploratory test pits. Because project conditions regarding type and location of structures and foundation loads can change and because subsurface conditions are not always similar to those encountered in the test pits, the geotechnical engineer must be contacted for review and possible revision of the recommendations if discrepancies are noticed. 6. RECOMMENDATIONS The following sections present recommendations regarding seismic considerations, foundations, lateral earth pressures, and for earthwork, excavations, drainage, and groundwater. 6.1 Seismic Considerations According to Figure No. R301.2, the site is in Seismic Design Category D2 The average properties in the in the top 100 feet are estimated to be N >50, therefore, the soil profile is considered stiff. The native site soils are not susceptible to liquefaction and therefore exhibit minimum seismic risk. 6.2 Foundations Conventional spread footing foundations may be used to support the proposed structures. Spread footing (continuous wall and individual column) foundations may be dimensioned using a net allowable bearing capacity of up to 2,000 psf if they are placed in the undisturbed, light brown, brown mottled reddish - brown, medium dense to dense SAND -SILT (SM) or SILT (ML) encountered at a depth of about 6 to 36 inches below the existing ground surface of the site. The foundations shall not be placed in the probable fill or above the relic topsoil encountered at the site in the vicinity of Test Pits 3, 6, and 7. Where fill is encountered, it shall be removed and the footings extended to bear in the undisturbed native soil. Alternatively, the fill shall be removed well beyond the footing width to a depth to expose the native soil. The removed fill may be placed in loose lifts not to exceed 10 inches and compacted. Each lift shall be compacted to at least 95 percent of the maximum laboratory density as determined by ASTM D1557 before placement of succeeding lifts. Bergquist Engineering Services Page 5 of 13 Compacted granular soils 35 psf /ft. Passive: Continuous footings 250 psf /ft. Column footings 300 psf /ft. At -Rest Detention Vault Walls 65 psf /ft A coefficient of friction between footings and bearing soils of 0.35 may be used to resist lateral foundation loads. If passive earth pressures are used in conjunction with base friction to resist lateral loads, reduce the ultimate coefficient of friction to 0.30. Footings, stem walls, and retaining walls must be reinforced to reduce the potential for distress caused by differential foundation movements. A qualified engineer must determine the size, quantity, and location of reinforcement. All footing excavations at this site must be inspected by the geotechnical engineer prior to placement of construction forms and reinforcement steel. 6.3 Slabs -on -Grade Slabs -on -grade must be supported on a minimum four -inch thick, free - draining sand or gravel base that follows gradation and compaction recommendations provided in Table 6.1 of this report. All concrete, especially slabs -on- grade, should be placed at minimum water- cement ratios on moistened surfaces and properly cured to minimize shrinkage, cracking, warping, and curling. Concrete slabs should be allowed to cure adequately before subjecting them to full Bergquist Engineering Services Page 6 of 13 Proposed Subdivision (Pieper Short Plat) March 8, 2005 Tukwila, Washington BES Project Number 200415, -Report 2 design loads. Any concrete that will be exposed to the elements should be entrained with four to six percent air to minimize damage from freeze -thaw cycles 6.4 Earthwork The recommendations presented in this report are predicated on fulfillment of the following earthwork recommendations. 6.4.1 Site Clearing: Strip and remove any topsoil, tree stumps, weeds, old rubble fill, concrete slabs -on- grade, and other deleterious materials from the project area prior to construction. After site clearing, the exposed surface must be graded relatively flat to allow for proper subgrade preparation but sloped slightly to allow good surface drainage during construction. 6.4.2 Excavation: Conventional- excavating equipment should be suitable for the proposed shallow foundation excavations. Use excavating buckets without teeth to excavate all foundations so as not to disturb the bearing surfaces. Shallow excavations (less than four feet in depth) will stand open with vertical side slopes for short durations: however, according to Chapter 296 -155, Part N of the Safety Standards for Construction Work in the State of Washington, the site soils classify as Type C. Therefore, side slopes of excavations deeper than four (4) feet must be no steeper than one and one -half (1.5) horizontal to one (1) vertical (1 .5H:1V). If the dimensions of the site prevent the use of maximum slopes of 1.5H:1V, the slopes must be stabilized or shored to facilitate safe excavations. The geotechnical engineer must be contacted for additional recommendations if such techniques are going to be employed. 6.4.3 Foundation Preparation: Except where fill is encountered, specialized treatment of the foundation soils is not anticipated at this site if the foundations are placed in the medium dense to dense SAND -SILT to SILT. The excavations, however, must be made carefully using a backhoe bucket without teeth so as not to disturb the bearing soils. If fill, loose, or soft soils are encountered at the footing elevation, they must be removed and replaced with properly Bergquist Engineering Services Page 7 of 13 U. : Stado rsf 5 : Pe rcent Pass` ing 3 -inch 100 3/4 -inch 50 -100 No. 4 25 -65 No. 10 10 -50 No. 40 0 -20 No. 200 0 -5* compacted backfill as described in Sections 6.4.5 and 6.4.6 of this report or the footings may be extended to bear on undisturbed, native soils. Proposed Subdivision (Pieper Short Plat) March 8, 2005 Tukwila, Washington BES Project Number 200415, -Report 2 6.4.4 Slab -On -Grade Preparation: If the earthwork recommendations provided in this report are followed, specialized treatment of the soil beneath slabs -on -grade at this site is not generally expected to be necessary. However, if any debris, organic material, organic fill soils, loose soils, or other deleterious materials are encountered at the subgrade elevation they must be removed and replaced with structural backfill. 6.4.5 Materials: The on -site topsoil, SAND -SILT (SM), and SILT (ML) soils are not suitable for use as structural fill or backfill. The organic -rich topsoil must only be used in landscape or non - structural areas. Site SAND -SILT (SM) and SILT (ML) soils are considered not to be all - weather soils and should be worked only during the dry season. The soils identified as "Probable fill" encountered at Test Pits 3, 6, and 7 are likely suitable for use as structural fill and backfill if removed and compacted in accordance with Section 6.4.6 of this report. If additional soil is needed for structural fill or backfill to meet design grades, it must be imported and conform to the gradation presented in Table 6.1, and be approved by the geotechnical engineer prior to use. Samples must be submitted to the geotechnical engineer at least 72 hours before approval is required and before the materials are used. Gravel base and select materials for pavement subgrade must conform to local governmental standards, such as City of Tukwila, King County, or other suitable specifications approved by the geotechnical engineer.

Granular materials used as a work blanket should conform to the gradation presented in Table 6.2, and be approved by the geotechnical engineer prior to use. TABLE 6.2 GRADATION REQUIREMENTS FOR WORK BLANKET *Note: The percent passing the No. 200 sieve is based on the weight of the material passing the 3/4 -inch sieve. 6.4.6 Placement and Compaction: Structural fill and structural backfill must be placed in relatively horizontal loose lifts not exceeding ten (10) inches in thickness and compacted to at least 95 percent of the modified Proctor (ASTM D1557) maximum density at moisture contents within two (2) percent of optimum. Backfill against detention vault walls must be carefully compacted to 90 percent of ASTM D1557 with light equipment so as not to impose excessive lateral loads on the walls. Structural fill /backfill must be placed under the full -time observation of a representative of the geotechnical engineer, and the specified compacted density and moisture content of each lift must be verified by test, prior to placement of subsequent lifts. Placement on frozen ground must not be attempted. 6.5 Drainage Good drainage is critical to the performance of earth - supported structures such as foundations and retaining walls. Therefore, construction grades and final site grades must be designed to prevent water from ponding in areas on or adjacent to foundations, slabs -on- grade, and pavements. Infiltration of water into foundation and utility excavations shall be prevented during construction and throughout the life of the project. A perimeter footing drain - system consisting of a perforated pipe surrounded by at least six inches of washed gravel will be required. The washed gravel must be separated from the surrounding soil by a filter fabric such as Mirafi 140N. The collected water must be tight - lined away from the building to a suitable discharge system but not discharged onto the top of Bergquist Engineering Services Page 9 of 13 SOIL UNIT GENERALIZED ENGINEERING PROPERTIES Vashon till Very slow infiltration rotes, excellent foundation stability, stands on steep natural and cut slopes for long periods, and good seismic stability. Proposed Subdivision (Pieper Short Plat) March 8, 2005 Tukwila, Washington BES Project Number 200415, -Report 2 schematic of a footing -drain system is presented on page A8 in the Appendix of this report. Where pavement does not immediately abut structures, slopes, with an outfall of at least three (3) percent for a minimum distance of five (5) feet from exterior footings, must be provided. 6.6 Groundwater Groundwater was encountered in the form of seepage at a depth of about three to four and one -half (3 to 41/2) feet below the surface in Test Pits 2, 3, 6, and 7. This is interpreted as the groundwater level at the time of the exploration. Test Pits 4, 5, and 8 were backfilled immediately after completion, therefore, groundwater levels were not determined. Groundwater seepage was not observed in Test Pit 1. The groundwater level should be expected to fluctuate due to seasonal variations in precipitation and numerous other variables. Groundwater at this site should not present significant problems during construction. If groundwater is encountered, shallow sumps with pumps should be sufficient to dewater shallow excavations. Pump water shall not be discharged onto or near the existing slopes. 6.7 Erosion The soils at this site classify as fine - grained SAND -SILT (SM) some gravel according to the Unified Soil Classification System. These soils have a relatively high erosion potential, however, because of the shallow slopes in the proposed construction areas on this site, properly placed silt fences and straw bales should be sufficient for erosion control even during periods of heavy rainfall.

XSTABL performs a two dimensional limit equilibrium analysis to compute the factor of safety for a layered slope according to either: (1) General Limit Equilibrium (GLE) Method, (2) Janbu's Generalized Procedure of Slices (GPS), (3) Simplified Bishop, or (4) Simplified Janbu. XSTABL calculates a FOS (factor of safety), which is the result of dividing the total forces supporting the slope by the total forces that are tending to destabilize the slope. If the FOS is greater than 1.00, the slope is considered stable; if the FOS is less than 1.00, the slope is considered to be unstable. A FOS of 1.00 indicates the slope is in perfect equilibrium. Because of the uncertainty regarding pertinent soil parameters used in the analyses and the variability of soil, slope, and ground water conditions, a non - seismic (static) FOS greater than 2.0 and a seismic (dynamic) FOS greater than 1.5 is recommended by the City of Tukwila for the proposed residential construction. Note: These properties are based on the recent subsurface exploration and are within the range of values suggested in a publication entitled Geotechnico /Properties of GeologicMatenak by Jon W. Koloski, Sigmund D. Schwarz, and Donald W. Tubbs Two cross- sections (labeled A -A' and B -B') of the existing slopes (see page A2) were analyzed for stability. Cross - section A -A' was at the steepest slope in the area of new construction. Cross - section B -B' was at the steepest slope that intercepts the proposed buried stormwater vault. The computer program was instructed to calculate the estimated FOS for 1600 potential shear surfaces during each iteration using one of the above - described methods. The attached graphs show the locations of the weakest surfaces analyzed within the slope segment selected for analysis, with the surface having the lowest FOS highlighted. Based on the analyses, the existing slope at A -A' has an estimated minimum factor of safety during static conditions of 2.409 against shallow failure (see page Al2 and A13) and 2.5 against deep- seated failure (see page Al 4 and A15.) The existing slope at A -A' has an estimated minimum factor of safety during seismic (dynamic) conditions of 0.30g against Bergquist Engineering Services Page 11 of 13 ,,, • • Observation and review of site clearing and review of all foundation excavations to evaluate whether actual conditions are consistent with those encountered during exploration. • Observation and testing of placement and compaction of all fill and backfill materials to evaluate compliance with specifications. Bergquist Engineering Services Page 12 of 13 Proposed Subdivision (Pieper Short Plat) March 8, 2005 Tukwila, Washington BES Project Number 200415, -Report 2 • Field inspection and laboratory testing of materials and field inspection of methods as required by the appropriate Uniform Building Code. Typically, this includes inspection of placement of reinforcing steel; inspection and testing of portland cement concrete to evaluate compliance with specifications regarding slump, temperature, air content, and strength. 7. REPORT LIMITATIONS The recommendations presented in this report are for the exclusive use of MR. Harry Singh for the proposed residential development on King County Parcel Numbers: 812500232 in Tukwila, Washington. The recommendations are based on the subsurface information obtained by Bergquist Engineering Services (BES) and on design details provided by Mr. Jim Jaeger of Jaeger Engineering. If there are any revisions to the plans or if deviations from the subsurface conditions noted in this report are encountered during construction, BES must be notified immediately to determine whether changes to the foundation recommendations are required. After the plans and specifications are more complete, the geotechnical engineer must be provided the opportunity to review them to check that these engineering recommendations have been interpreted properly. oOo Bergquist Engineering Services Page 13 of 13 XIONBddV 1 1 ! 1 1 1 1 1 !

These letters requested revisions and additional information regarding the Pieper Short Plat application. I have revised the short plat plan and the civil site plan based upon the comments in those letters. The geotechnical engineer is preparing the revised geotechnical report based on Bulletin B4. He is scheduling the field testing and should be completed in two weeks. I will submit the new geotechnical report upon its completion. I am also meeting with the resident of the site to review the drainage issues that were raised in the two letters from the area residents. I will respond to those letters after my site meeting. I wanted to submit the revised plans at this time so that we could finalize the lot layout and prepare the legal description of the proposed lots. I have addressed the items in the letters and memo as follows: Your letter of November 9: 1. I have revised the short plat plan per the redlines. The redline plan is attached for your reference. I have not included the proposed lot legal descriptions because I want to wait until the proposed lot layout is confirmed. 2. I have revised the driveway for lot 3 to include an easement for lot 2 so that they may share driveways. 3. l have revised the driveway easement for lot 7 across lot 8 so that the driveway distance is shorter. -I am now showing 125' from the bulb tract line to the lot line for lot 7. This should allow the house for lot 7 to be less than 150' from the edge of the bulb. I am also showing a new hydrant at the end of the bulb. See the civil site plan sheet for the 125' measurement length. 4. I will coordinate with the surveyor to prepare the final lot legal descriptions. 5. The building setback lines have been added to each lot. 6. Joint maintenance agreements will be prepared, approved by the City and recorded prior to the short plat approval. Civil Plans: 1. I have added the proposed contour lines to the civil site plan. 2. 1 have added the schematic designs for the water and the dry utilities to the civil site plan. The letter of January 14: Memo from Public Works 1. I have revised the SEPA section B.1 to match the geotechnical report. 2. I am attaching the completed ESA addendum to the SEPA checklist. 3. The easement referenced in the title report is actually within the right -of -way for 53 Ave. S. It is shown on the civil site plan. 4. I will have the geotechnical engineer address the detention vault being within the 25' BSBL from the top of slope buffer. His BSBL recommendations was for house structures. 5. The geotechnical report is being revised. 6. I understand that the new road will remain private. I have revised all of the plans to show the road as a private road, within Tract A. II. Fire Department: 1. I am showing access to lot 7 on both plans via an easement across lot 8. 2. It is noted that all houses shall be within 150 ft. of a fire hydrant. III. Building Department: 1. A note has been added to the plans that the existing garage will be removed. 2. The geotechnical report will address this item. 3. The geotechnical report will address this item. Again, I will be submitting the revised geotechnical report and a response to the residents letters in a separate submittal. Please call me with any concerns or questions.

Mullet, Mayor Department of Community Development Steve Lancaster, Director Re: Request for additional information Short Plat application. File numbers L04 -070 and E04- 020. Dear Mr. Jaeger: The letter of complete application was mailed to you on November 9, 2004, which also included comments from the Planning Department. After the city received confirmation from you that the notice board had been installed, the notice of application was posted and mailed on December 9, 2004. In response to the notice of application, the city received two comments letters from the residents in the general area of the proposed short plat. The comment letters raise potential drainage issues with the proposed short plat. Please review the letters and provide response to the issues raised. Also, the various departments of the city have reviewed your application and have the following comments: II. Fire Department: 1) Access to lot 7 not shown. 2) Fire Hydrant spacing shall be able to provide coverage so that no proposed structure is more than 150 feet from a fire hydrant. 1) The detached garage must be removed or relocated prior to final plat approval. The existing garage does not meet setback requirements from the proposed property lines. Also, a garage is an accessory use in LDR zoning is only allowed as an accessory use to a residence. 2) The "generalized engineering properties" of the soils as interpolated from the reference geologic map dated 1962, will not be adequate as basis for determining foundation design. Soil classification and foundation design recommendations for each lot will be required for building permit application. 6300 Southcenter Boulevard, Suite #100 • Tukwila, Washington 98188 • Phone: 206 - 431 -3670 • Fax: 206 - 431 -3665 If you have any questions, you can reach me at 206 - 431 -3685.

COMMENTS: REF FILE E04 -020 December 22, 2004 City of Tukwila Attn:Minnie Dhaliwal 6300 Southcenter Blvd #100 Tukwila, WA 98188 Ref: File Number E04 -020 n t r 3 2004 P1 CENTER Comments Regarding Short Plat Application, File Number E04 -020, pursuant to Notice dated 12/09/04 (Lot 23 of Sunrise View Addition). I feel further study needs to made of proposed short plat File Number E04 -20 prior to approval. From living here for the past 12 years, the water table, drainage (natural and artificial), and limited access have not been adequately addressed in the proposal to satisfy the concerns and effects this will have on the surrounding properties. I first request that you extend the comment period on this proposal until January 31 2005. A short-plat development application with a limited comment period of 15 days is inadequate for this potentially sensitive project and ill timed for the holidays. The following comments should be viewed with a plat map of the Sunrise View Addition at hand. I reside on the East Parcel of Lot 17. The subdivision is proposed for Lot 23. A crude diagram made by myself is attached (page 4). Drainage It has been known that properties to the west and north of Lot 23 have experienced excessive standing water and increasing SeaTac run -off by their down -slope location from other properties developed up -slope of the Sunrise View Addition. Any potential blockage /obstructions could induce flooding within existing and proposed properties and even potential landslide under severe rainfall considering the slope of proposed property relation to Interstate 5. Our properties may be wet because of soil type, misdirected run -off, improper drainage, or a combination of all the above; however, further development without wetland evaluation, water table determination, and soil type testing will only exacerbate the problem. Location of Plat and Subsequent Access The proposed plat of Lot 23 is located on a dead end street in the city of Tukwila and on the city boundary line between SeaTac and Tukwila. The street (53` Ave S.) appears to be shared by both cities, however most of the increases in traffic, road maintenance, and ramifications will be borne by the city of SeaTac by its access and roads leading to commercial centers via S. 170 St. Page 1 of 4 COMMENTS: REF FILE E04 -020 Status of Drainage (Limited to Knowledge of E. Gipson) A piped -18 "drainage exists that runs into an open pipe terminating at the west property line (51 Ave S.) between properties 16 and 17. This further runs east into an open trench that runs along the Lot 16 & 17 property line, turning south along the western property line dividing the two parcels of Lot 17. It further continues under a private roadway for Lot 17 across Lot 20 and angling into Lot 22. This is pertinent because the sheer volume of water, by this drainage can, does, and/or will affect the drainage of properties to the West, East, and South of Lot 20, and possibly adjacent/including Lot 23 (proposed subdivision). An increase in volume or downstream blockage has the potential of severe damage to existing properties without proper surface and ground water management by the city /s designated departments. This drainage was represented to me, by the City of SeaTac as "untouchable" because of its "classification" as early as 1992. It has been later disclosed that this "run - off/drainage" had no special status and was from storm drains located upslope of the Sunrise View Addition properties. The open trench remains dry during the summer months and is a torrent during heavy /steady rains. This can potentially wash out the access to my home should the drainage water volume increase any further. The volume of this drainage pipe /trench has increased over the years and has even eroded parts of Lot 20, exposing a water main. This was not evident until non - native Himalayan Blackberry bushes were removed by the owner a few years ago. The reasoning and authority of the City of SeaTac to route this large amount of drainage across our properties remains in question (this has not yet been explored). There are no easements /rights of record allowing open drainage across our properties. This may affect Lot 23 development. Future Development of Lot 18 While Lot 18 is within the city limits of SeaTac, it is pertinent to these comments because, I was informed the developer of Lot 23 is the same person/organization contemplating development/subdivision of the Western parcel of Lot 18 into six additional parcels and the same questions and considerations are in order as Lot 23 is contemplated. I became aware of plans to develop the western part Lot 18 on Friday December 17, 2004. A surveyor arrived at my home to request access to my property to mark corners. I would not allow him access until the person answered questions regarding his purpose of the survey. Do not blame the surveyor for information I received. I would not have allowed access to my property without the answers. The application of this short plat, notice thereof, has not yet been received. This parcel considered is only 23,000 square feet. I presumed I heard this information (six parcels) in error, however one of the adjacent neighbors confirmed that this was the intention of the survey. I am not aware of any laws /ordinances that would allow this size of lot in the City of SeaTac. Page 2 of 4 , • • COMMENTS: REF FILE E04 -020 Summary of Comments Incorporated cities of King County should exercise additional caution in approving these types of mini subdivisions. While the targeting of our larger residential properties within city boundaries for development may be an unintended consequence of the passage of the King County CAO (Critical Areas Ordinance), I hope our city leaders will attempt to maintain/preserve our few green spaces balanced against property rights and quality housing (versus quantity). I do not oppose development per se and I want SeaTac and adjacent cities to carefully evaluate proposed development from a technical/engineering standpoint as to not cause economic /physical harm to existing properties. I wish to become a party of record as described in your notification.

Those conditions are not shown on the survey and are not addressed in the preliminary Technical Information Report (TIR). PW received a preliminary drainage analysis on 11.08.04. This report was reviewed and approved 11.10.04 by Ryan Larson. PW review is completed and PW comments have been sent (08.06.04 and revised 12.07.04). I recommend that you notify the applicant, the engineers and the surveyor regarding the comments you have received. The civil engineer, the geotechnical engineer and the surveyor should receive a copy of the comments. Both engineers should consider the comments and revise their reports as needed. L. Jill Mosqueda P.E. CC: Ryan Larson To: City of Tukwila 12/21/03 Department of Community Development From: John Discher 17056 51 Ave. S. SeaTac, WA 98188 Subject: Comments on files below: File Number E04 -020 (SEPA) L04 -070 (Short Plat) The only concerns I have concerning the proposed short plat and SEPA, and what I assume as miscellaneous permits (fill and grade, drainage, etc) have to do with how the developer intends to handle the drainage of surface and groundwater that has historically flowed into the NW corner of the property from the hills above. There is currently a storm water pipe above the property located on the northern property line of 17046 51 Ave. S. that was installed in the 1950's that handles all the surface water run -off from approximately 170 St. to 173 St. and Military. It handles a significant amount of water. This water flows through private property from 17046 to 17056 51 Ave.S. and then crosses the NE corner of the adjoining property before flowing into what is shown as lot 3 on the survey I was provided. I feel it is very important that the developer address this issue carefully, as flooding has been an issue in the past. As far as the short plat goes, I think that the minimum lot size is too small. The offsets at the property lines will be minimal, creating a very crowded feel for all residents. Thank you for allowing me to express my opinion and I hope that any and all issues can be resolved to everybodys satisfaction. Sincerely, John Discher RECEIVED DEC 2 1 2004 PERMIT Ctmt,.

Sincerely, Nora Gierloff Planning Supervisor cc: Public Works Fire Department Q: \LETTERS\PieperComplete.DOC INFORMATIONAL MEMORANDUM To: Mayor Mullet and City Council Members From: Director Public Works Subject: Mr. Pieper's Appearance Before City Council on August 8, 2004 and his Request for Waiver From City Standards for Subdivisions and Plats ISSUE: Mr. Pieper has requested a waiver from the requirements contained in Tukwila Municipal Code Title 17 Subdivisions and Plats and from the requirements contained in the City's Infrastructure Design and Construction Standards for construction of the roadway, curbs, gutters, sidewalks, and surface water drainage requirements associated with the "potential" development of his property at 17083 53` Ave. South. See Attachment 1. BACKGROUND: In March of 2004, Mr. Pieper met with City Staff to discuss what would be required to obtain an approval for a proposed 8 -lot Short Plat. Topics discussed were geotechnical concerns (steep slopes), surface water drainage requirements, frontage improvements, utilities — Water is served by Highline Water District; sewer is served by Val -Vue Sewer District, etc. Mr. Pieper was provided with all of the documentation needed to submit an application. On April 8, 2004, City Staff met with Mr. Steve Peeler, the potential buyer of Mr. Pieper's property. During the pre - application meeting with Mr. Peeler, the requirements, including the standards for constructing the street, curbs, gutters, surface water drainage, and sidewalks (See Attachments 2, 3, 4, and 5), for a proposed 8 -lot short plat were identified and presented by City Staff. Additionally, the applicant was told that water, sewer, and power would have to be provided. Representing the applicant were Mr. Peeler and Mr. Luxmore of Luxmore Homes and Mr. Goodmanson of The Goodmanson Group. Representing the City was staff from Permit Center, Public Works, Building Official, Planning Department, and Fire Department. According to Mr. Pieper, the potential buyer considered the cost of the property and infrastructure to be too high and asked to be released from the purchase agreement. Mr. Pieper agreed and decided to proceed on his own and possibly sell the individual lots. Approximately one week after the April 8 pre - application meeting, Mr. Pieper and City Staff met to discuss the results of the aforementioned April 8 pre - application meeting. Again, Mr. Pieper and City Staff went over all of the requirements associated with a short plat. See Attachments 6 and 7. On May 18 2004, Public Works received Mr. Pieper's request for a waiver of City standards, Attachment 8. Mr. Pieper requested: • A reduction in the street width; • Waive the requirement for sidewalks; • In lieu of standard curbs, allow a rolled asphalt curb; • In lieu of the required street surface water drainage system (Gutters, catch basins, etc.), approve a system that allows the water from the street to enter open drainage ditches; and • In lieu of streetlights, require the homeowners to provide yard lights. On May 25, 2004, Public Works responded by stating that Mr. Pieper's request had been reviewed and that with the exception of street lighting along the internal street, none of the other standards would be waived. See Attachment 9. On May 27 2004, City Staff met with Mr. Pieper for a pre - application meeting. Mr. Pieper presented a preliminary plan for a 9 -lot short plat, Attachment 10. Representatives from the Permit Center, Planning, Public Works, Building Official, and Fire were present. Again, Mr. Pieper was presented a copy of the standards, forms, and bulletins in an effort to assist with his short plat proposal. On August 9, 2004, Mr. Pieper spoke before the City Council. On August 10, 2004, Mr. Pieper wrote to the City Council, Attachment 11. Included in his letter is a chronology of events, a statement that he is unable to find a variance procedure within the City's Subdivision Code, a copy of a "letter" dated August 5, 2004 to which he is requesting a response, and because he has not received an approval of his waiver request, he is asking the City Council to intervene and "format" a variance or resolve the "problem." His letter dated August 5, 2004 requests the following changes to the specified requirements of Title 17, Subdivision Code and City Design and Infrastructure Standards: 1. In lieu of a 28 -foot paved surface, provide a 20 -foot paved surface with a commensurate reduction in the width of the right -of -way; 2. Eliminate sidewalks on both sides of the street; It is not clear from the August 5 letter if the request for a rolled asphalt curb in lieu of the standard curb and if open drainage ditches in lieu of a proper surface water drainage system for the street as requested in Mr. Pieper's May, 2004 is still being sought. ANALYSIS Issue: Mr. Pieper during his August 9, 2004 comments to the City Council alleged that he has been unable to "get an audience with the Engineering or Planning Department." Staff Response: In addition to the aforementioned five formal meetings, City Staff, including 4 individual s from the Planning Department, 4 individuals from 2 Public Works, Council's Legislative Analyst, the Mayor's Executive Secretary, and the Mayor himself have met with Mr. Pieper in separate meetings to discuss his proposal and request for waiver. As recently as August 24, 2004, Mr. Pieper met with Planning and Public Works staff. Additionally, it is standard practice for staff to make a site visit before each pre - application and several Public Works employees have visited Mr. Pieper's property. Issue: Mr. Pieper during his August 9, 2004 comments to the City Council alleged, "He cannot find a variance procedure." Staff Response: TMC Chapter 17.28 Exceptions, Penalties, Severability, Liability provides both the criteria and procedures for the City to address "variances" to the TMC. TMC 17.28.010 states, "An application for any exception from this code shall be submitted in writing by the subdivider, as part of the application for short subdivisions, binding site improvement plan, or preliminary plat." It is noted that Mr. Pieper has not submitted an application to the City, nor has he developed any formal plans for his property. Issue: The focus of Mr. Pieper's waiver request, both in the May and August letters is to change the standards for the required frontage improvements. Mr. Pieper requests: • In lieu of the standard 28 -foot width for a residential access street, Mr. Pieper proposes a 20 -foot width. Staff Response: Mr. Pieper's property has a potential for 9 individual residences. If the width of the street were to be reduced to 20 feet of paved surfaces, then, for public safety, on- street parking would not be allowed because sufficient room is needed for safety vehicles to access the area and for two vehicles to safely pass each other. If on- street parking is not allowed, then the City will be inviting the displeasure from the future homeowners — Where does the City expect guests, family members, etc to park when visiting the homeowners? • In lieu of sidewalks, Mr. Pieper proposes to have sidewalks on just one side or none at all. Staff Response: City policy is to create a walkable community. Sidewalks are needed to ensure pedestrian safety. If the City were to authorize sidewalks on just one side, which half of the potential homeowners receive the enhancements and which do not? Does the City instruct the developer to stop the sidewalks at the top of the cul -de -sac? If the City authorizes a waiver of the sidewalk requirement, is a new policy being established? 3 • In lieu of standard curbs, Mr. Pieper requests a rolled, asphalt curb. SUMMARY Staff Response: Rolled asphalt curbs do not withstand the rigors of street traffic. Homeowners have a tendency to drive over them when parking. They rapidly become a maintenance expense for the City. • In lieu of the required street surface water drainage system comprised of curbs, gutters, catch basins, etc. allow the water to enter open drainage ditches. Staff Response: The City has adopted the King County Surface Water Design Manual and has the responsibility under its National Pollutant Discharge Elimination System Permit to properly control and manage surface water drainage. Mr. Pieper's proposal does not meet any reasonable standard for managing the street runoff. Both recent and past experience has demonstrated that if the City were to allow Mr. Pieper's "open drainage" system, the City would be bombarded with requests from the homeowners to cover the ditches, provide a proper drainage system in order to protect children's safety, prevent automobiles from driving into the ditches, provide more parking in front of the residences, etc. • In lieu of streetlights, require the homeowners to provide yard lights. Staff Response: Mr. Pieper has been informed that a single streetlight at the entrance to his property would be satisfactory. Mr. Pieper has had full and unfettered access to the Public Works and Planning Departments. City staff has spent hours working with Mr. Pieper. Mr. Pieper's waiver request, if granted, would result in a 9 -lot subdivision served by substandard infrastructure. This would cause the City additional maintenance expenses. From recent and past experiences where this type of poor development had been allowed by King County, the City has had to expend scarce resources to provide a safe and pleasant neighborhood for its residents. In consideration of the above, a letter, signed by the Public Works Director, denying Mr. Pieper's waiver request has been sent, Attachment 12. 4 !Plii!IRINIOPP Bergq ist Engineering Services 27207 8th Avenue S P.O.

Waldron, Bruce A Liesch, Donal R. Mullineaux, and Dwight R. Crondell and dated 1962. In addition, I have discussed the revised layout plan of the proposed road, lots and drainage pond with Jim Jaeger of Jaeger Engineering. The Based on my site visit on July 19 and 23, 2004, the site conditions are consistent with the topographic survey. Most of the 3.09- acre site is relatively flat and level but the properly incorporates a north - northeast to south - southwest trending steep slope that roughly parallels Interstate 5 along the east and southeast side of the properly. The steep slopes decline from approximate crest elevation of 240 feet to approximate elevation 160 feet at slopes ranging from 60 to about 900 percent. The slopes are covered with a moderately dense stand of predominantly large leaf maple trees. Several of the trees along the northernmost portion of the property are bowed slightly, which indicates that there has been some creeping of the slope. L01k01° SOIL UNIT GENERALIZED ENGINEERING PROPERTIES Younger Gravel Moderate infiltration rates, fair to excellent foundation stability, generally unstable on slopes steeper than 30° (75 percent) and good seismic stability. Vashon till Very slow infiltration rates, excellent foundation stability, stands on steep natural and cut slopes for long periods, and good seismic stability. Proposed Pieper Short Subdivision Tukwila, Washington BES Proje umber: 200415, Report 1 July 29, 2004 The paved walk southeast of the existing Pieper residence are cracked and slightly offset down suggesting that the slope has been creeping over time. South of the existing house, there are some shallow earth fissures about 25 feet from and parallel to the major slope- break. Mr. Pieper reported that years ago, he had placed fill on the surface of the site, south of the existing house. According to him, the fill thickness ranges from zero feet along a line about 25 feet west of the major slope break to about four feet in thickness at the major slope break (See attached drawing for the described features.) The project site is underlain predominantly by a Vashon till. Overlying the Vashon till, there appears to be thin layer of younger gravel, possibly recessional ouiwash. The generalized engineering properties of these soil units, as described on the aforementioned geologic map, are as follows: The slope stability analyses for this study were performed using XSTABL software developed by Interactive Software Designs, Inc. XSTABL performs a two dimensional limit equilibrium analysis to compute the factor of safety for a layered slope according to either: (1) General Limit Equilibrium (GLE) Method, (2) Janbu's Generalized Procedure of Slices (GPS), (3) Simplified Bishop, or (4) Simplified Janbu. XSTABL calculates a FOS (factor of safety), which is the result of dividing the total forces supporting the slope by the total forces that are tending to destabilize the slope. If the FOS is greater than 1.00, the slope is considered stable; if the FOS is less than 1.00, the slope is considered to be unstable. A FOS of 1.00 indicates the slope is in perfect equilibrium. Because of the uncertainly regarding pertinent soil parameters used in the analyses and the variability of soil, slope, and ground water conditions, a non - seismic FOS greater than 1.25 is generally recommended for residential construction Bergquist Engineering Services Page 2 of 4 SOIL UNIT ENGINEERING PROPERTIES USED IN STABILITY ANALYSIS Moist Unit Weight Cohesion (C) Angle of Internal Friction (c) Younger Gravel 132.0 pcf 0 psf 30° Vashon till 138.0 pcf 1,000 psf 35° Proposed Pieper Short Sub Tukwila, Washington Materialsby Jon W. Kdoski, Sigmund D. Schwarz, and Donald W. Tubbs BES Projeumber: 200415, Report 1 July 29, 2004 Note: These properties are the lowest values suggested in a publication ni es of (edog The program was instructed to calculate the FOS for 1600 potential shear surfaces during each iteration using one of the described methods. The attached graphs show the locations of the weakest surfaces analyzed within the slope segment selected for analysis, with the surface having the lowest FOS highlighted. Based on the analyses, the existing slope has an overall minimum estimated factor of safety against failure without earthquake loads of 1.084 (See page A3). During a seismic event producing a horizontal acceleration of 0.20g, the minimum factor of safety is 0.817. The failure surface is about 45 feet from the crest of the slope (See page A4). The slope was then analyzed by forcing the failure surface through a point 50 feet from the crest of the slope. The factor of safety without seismic loads is estimated to be 1.438 (See page A5.) The factor of safety with seismic loads is estimated to be 1.384 (See page A6.) Accordingly, we recommend that a buffer of 25 feet from the crest of the slope and a building setback of 25 feet from the buffer be established. Construction and disturbance of vegetation within the buffer shall be permitted. No significant structures such as residential buildings or garages shall be constructed within the 25 -foot area between buffer and building setback line. The vegetation on the slope shall be maintained over the life of the project. The soils along the toe of the slope shall not be disturbed or removed.

SINGH — 9 LOT SHORT PLAT SHORT PLAT # L04 -070 PW05 -058 The project is located in the SW1 /4 & NW1 /4, of the SW1 /4 of Section 26, Township 23 North, Range 4 East, W.M., adjacent to 53` Ave. South; and within a private street named South 172 Lane, in the City of Tukwila. The site address is 17083 — 53 Ave. South, Tukwila, WA 98188. The Tax Parcel Number is 812520 -0232. This project proposes to develop approximately 3.13 acres of existing, tall grasses and a few small deciduous trees. The underlying soils vary from sand silt, sandy silt, and medium to dense sand. Catch basins and storm drainage pipes will be installed within the private street and adjacent areas to convey runoff to a Private Underground Detention/Water Quality Vault located in the eastern portion of the site. Roof downspouts will be individually tightlined to the catch basins, which is tightlined to a public storm conveyance system, located South of the Paved 53 Ave. South end of road. The off -site area is not considered as part of the private detention vault sizing. After development, approximately 1.09 acres of the site is impervious, with the remaining 2.04 pervious acres consisting of lawns, landscaping, etc. The goal of the plan is to treat all on -site runoff for water quality by directing flows to a Detention / Water Quality facility. The detention vault is designed to retain runoff volumes up to the 2 year, and 10 -year storm events; with 7 inches of freeboard. The catch basins shall have stenciled next to them "DUMP NO WASTE - DRAINS TO STREAM ". Activity that involves pollutants shall be done under a covered area. The private street shall be cleaned and swept as necessary to remove debris. Treatment BMP's Interceptor swales were constructed intercepting silt -laden runoff from the site during clearing and directed the runoff to temporary traps for treatment of water before releasing down stream from the site. These facilities were design for 2/3 of 2 -year storm event. Inspection Inspect the storm detention /water quality vault, at least twice a year, especially after periods of heavy runoff. Maintenance records must be kept for five (5) years and available for City Inspector review. Maintenance To ensure proper water quality treatment, the wet vault designed to allow for a minimum of 6 -inch sediment at the bottom of the vault, which will be removed at a regular schedule. In the addition for the bottom 6 -inch of sediment, the vault is designed with a minimum dead - storage of three feet to allow silt -laden runoff to settle at the bottom of the vault.

OCT Fo o•o ?04 N PIEPER SHORT PLAT ° - fT DISCUSSION OF PROJECT CONSISTENCY The Pieper 9 lot short plat is consistent with the decision criteria for a City short plat based on the following arguments: 1. The proposed short plat is consistent with the comprehensive plan and the current zoning, which is LDR. The proposed short plat will have a density of 2.88 units per acre. The low density is due to the presence of steep slopes and adjoining buffer that remove 1.30 acres from the developable area. The proposed minimum lot size is 6500 SF. The proposed minimum lot width is 50 ft. All these parameters meet the criteria for the LDR zone. 2. Provisions have been made for the drainage and utilities that will serve the proposed short plat. The drainage system will include an on -site drainage facility located in a separate tract (Tract A). The sanitary sewer service will be provided by Val Vue Sewer District via an existing sewer main all along the west property line and an existing man hole within 53 Ave. S. at the northeast property corner. Water service will be provided by Highline Water District and will be delivered from the existing water main located at the northeast corner. A new water main will be extended along the proposed cul -de -sac. Erosion control will be managed using best management practices that are shown on the erosion control plans that will be approved by the City. 3. Necessary provisions will be made for access to the proposed lots by the proposed construction of a new internal cul -de -sac road. This road will connect to the existing terminus of 53rd Ave. S. and will include a turnaround bulb at its end. The new road will be a public road and will be constructed to City public road standards. 4. The proposed road right -of -way to be dedicated is shown on the preliminary short plat plan. This new ROW and the drainage tract will be dedicated to the City upon final approval and recording of the short plat. Proposed private access easement is shown on the plan and will also be executed with the final short plat approval. b10 5. The proposed lots meet all of the requirements of the LDR zone. All of the lots, except lot #7, will have access to the new public road. Lot #7 will access from a private easement. The lots that area adjacent to the steep slope area will observe a 25' building setback, as recommended by the geotechnical engineer. A 25' buffer from the top of the slope is in addition to the buffer. The lots are oriented so that a minimum number of lots will be adjacent to the 1 -5 freeway, to minimize the noise impact on the new houses.

Continue to the next question as directed for each No or Yes answer. 1 -0 Will the project require any form of grading? Grading is defined as any excavating, filling, clearing, or creation of impervious surface, or any combination thereof, which alters the existing ground surface of the earth (see Tukwila Municipal Code (TMC) Chapter 18.06, Zoning Code, Page 18 -11). Please circle appropriate response. NO - Continue to Question 2 -0 Continue to Question 1 -1 (Page 3) 2 -0 Will the project require any form of clearing? Clearing means the removal or causing to be removed, through either direct or indirect actions, any vegetation from a site (see Chapter 18.06, Page 18 -8). Please circle appropriate response. NO - Continue to Question 3 -0 Continue to Question 2 -1 (Page 4) 3 -0 Will the project require work, during any time of the project, below the ordinary high water mark of a watercourse or the Green/Duwamish or Black Rivers or in wetlands? Ordinary high water mark is the mark that is found by examining the bed and banks of a stream and ascertaining where the presence and action of waters are so common and usual as to distinctly mark the soil from that of the abutting upland, in respect to vegetation (see TMC Chapter 18.06, Page 18 -15). Please circle appropriate response. NO Continue to Question 4 -0 YES - Continue to Question 3 -1 (Page 5) 4 -0 Will the project result in the processing or handling, storage, or treatment of hazardous substances? This does not include the proper use of fuel stored in a vehicle's fuel tank. Hazardous substances are any liquid, solid, gas, or sludge, including any material, substance, product, commodity, or waste, regardless of quantity, that exhibits the characteristics or criteria of hazardous waste as defined by Washington Administrative Code 173 -303 (see TMC Chapter 18.06, Tukwila Zoning Code, Page 18 -11). This includes fuel or other chemicals stored on - site during construction. Please circle appropriate response. NO Continue to Question 5 -0 YES - Continue to Question 5 -0 5 -0 Will the project result in the withdrawal, injection, or interception of groundwater? Examples of projects that may affect groundwater include, but are not limited to: construction of a new well, change in water withdrawals from an existing well, projects involving prolonged construction dewatering, projects installing French drains or interceptor trenches, and sewer lines. For the purpose of this analysis, projects that require a geotechnical report pursuant to the requirements of TMC 18.45.060 and 18.45.080E.4, or would require a geotechnical report if not exempt under TMC 18.45.080A, should answer Yes. Please circle appropriate response. NO Continue to Question 6 -0 YES - Continue to Question 6 -0 Part A (continued) 6-0 Will the project involve landscaping or re- occurring outdoor maintenance that includes the regular use of fertilizers, pesticides, or herbicides? This does not include the one -time use of transplant fertilizers. Landscaping means natural vegetation such as trees, shrubs, groundcover, and other landscape materials arranged in a manner to produce an aesthetic effect appropriate for the use of the land (see TMC Chapter 18.06, Tukwila Zoning Code, Page 18- 13). For the purpose of this analysis, this includes the establishment of new lawn or grass. Please circle appropriate response. NO — Checklist Complete Checklist Complete Part B: Please answer each question below for projects that include grading. Review each question carefully, considering all phases of your project including, but not limited to construction, normal operation, potential emergency operation, and ongoing and scheduled maintenance. Continue to the next question as directed for each No or Yes answer. 1 - 1 Will the project involve the modification of a watercourse bank or bank of the Green/Duwamish or Black Rivers between the ordinary high water mark and top of bank? This includes any projects that will require grading on any slope leading to a river or stream, but will not require work below the ordinary high water mark. Work below the ordinary high water mark is covered in Part C. Please circle appropriate response. Continue to Question 1 -2 YES - Continue to Question 1 -2 1 -2 Could the construction, operation, or maintenance of the project result in sediment transport off site or increased rates of erosion and/or sedimentation in watercourses, the Green/Duwamish rivers, or the Black River? Most projects that involve grading have the potential to result in increased erosion and/or sedimentation as a result of disturbances to the soil or earth. If your project involves grading and you have not prepared a Temporary Erosion and Sedimentation Control Plan specifically designed to retain 100 percent of the runoff (including during construction) from impervious surface or disturbed soils, answer Yes to this question. If your project is normally exempt under the Tukwila Municipal Code and would not require the preparation of a Temporary Erosion and Sedimentation Control Plan, BUT may still result in erosion or sediment transport off site or beyond the work area, answer Yes to this question. Please circle appropriate response. Continue to Question 1 -3 YES - Continue to Question 1 -3 1 -3 Will the project result in the construction of new impervious surfaces? Impervious surfaces include those hard surfaces which prevent or restrict the entry of water into the soil in the manner that such water entered the soils under natural conditions prior to development; or a hard surface area that causes water to run off the surface in greater quantity or at an increased rate of flow from the flow presented under natural conditions prior to development (see TMC Chapter 18.06, Tukwila Zoning Code, Page 18 -12). Such areas include, but are not limited to, rooftops, asphalt or concrete paving, compacted surfaces, or other surfaces that similarly affect the natural infiltration or runoff patterns existing prior to development. Please circle appropriate response. NO - Continue to Question 2 -0 (Page 2) - Continue to Question 1-4 1-4 Will your project generate stormwater from the creation of impervious surfaces that will not be infiltrated on site? For the purpose of this analysis, infiltration includes the use of a stormwater treatment and management system intended to contain all stormwater on site by allowing it to seep into pervious surface or through other means to be introduced into the ground. If your project involves the construction of impervious surface and does not include the design of a stormwater management system specifically designed to infiltrate stormwater, answer Yes to this question. Please circle appropriate response. N Q. - Continue to Question 2 -0 (Page 2) (YES) Continue to Question 2 -0 (Page 2) Part C: Please review each question below for projects that include clearing.

Please circle appropriate response. 3 -1 Will the project involve the direct alteration of the channel or bed of a watercourse, the Green/Duwamish rivers, or Black River? For the purpose of this analysis, channel means the area between the ordinary high water mark of both banks of a stream, and bed means the stream bottom substrates, typically within the normal wetted -width of a stream. This includes both temporary and permanent modifications. Please circle appropriate response. NO - Continue to Question 3 -2 YES - Continue to Question 3 -2 3 -2 Will the project involve any physical alteration to a watercourse or wetland connected to the Green/Duwamish River? For the purpose of this analysis, "connected to the river means" flowing into via a surface connection or culvert, or having other physical characteristics that allow for access by salmonids. This includes impacts to areas such as sloughs, side channels, remnant oxbows, ditches formed from channelized portions of natural watercourses or any area that may provide off channel rearing habitat for juvenile fish from the Duwamish River. This includes both temporary construction alterations and permanent modifications. Watercourses or wetlands draining to the Green/Duwamish River that have a hanging culvert, culvert with a flap gate, diversion, or any entirely man-made or artificial structure that precludes fish access should answer Yes to this question. Please circle appropriate response. NO - Continue to Question 3 -3 YES - Continue to Question 3 -3 3 -3 Will the project result in the construction of a new structure or hydraulic condition that could be a barrier to salmonid passage within the watercourse or the Green/Duwamish or Black Rivers?
