(ZZA) has completed a geotechnical evaluation for the w w above - referenced short plat. This report presents the results of our subsurface exploration and 2 o geologic reconnaissance relative to general foundation and construction considerations, as well p o N as the City of Tukwila Sensitive Area designations for the project site. The field evaluation was ° 1-- completed on March 6, 2000. I v The purpose of the evaluation was to establish general surface and subsurface conditions z at the site from which conclusions and recommendations regarding foundation design and Cu _ construction considerations could be formulated, and to address Sensitive Area designations as O x defined by the City of Tukwila. The scope of our work consisted of subsurface test pit z explorations, a visual reconnaissance, geotechnical engineering analyses, and preparation of this report. We expect that changes in existing site grades will be minor. For purposes of preparing this report, we have assumed that changes in existing site grades will be on the order of 1 to 2 feet. In the event of any changes in the nature, design, or location of the proposed structures, the conclusions and recommendations presented in this report should be reviewed and modified, if necessary, to reflect the changes. We recommend that ZZA be allowed the opportunity to review the plans and specifications for the project once they become available to determine that the recommendations presented herein have been properly interpreted with respect to this project. This report has been prepared in accordance with generally accepted geotechnical engineering practices for the exclusive use of Keystar Corporation and their agents, for specific application to this project. SITE AND PROJECT DESCRIPTION The project site is located on the south side of South 126 Street between 40 Avenue South and 41 Avenue South in Tukwila, Washington. The site is slightly larger than one acre in - size and is currently unoccupied. Portions of the site had been stripped, but remaining vegetation 19231.36 Avenue W >, Suite B201 Lynnwood, Washington 98036 (425) 771- 3304 14 ryrw. ,w�17N�N+'ti1�74kr'x77 'PWfnrrR:. r te.:! -._-:. - 6 Lot Short Plat on South .26 Street Tukwila, Washington J -671 March 13, 2000 Page 2 consisted of weeds, small shrubs, blackberry bushes, and scattered trees to over 2 feet in diameter. Site topography slopes downward to the southwest and varies from relatively level along the eastern margin of the site to slopes approaching 50 percent nearer the center of the site where Lot 5 is planned. Total relief across the site is on the order of 38 feet. Based upon preliminary site plans, we understand that the proposed development will consist of six single - family residential lots. Finished floor elevations and grading plans were not provided at the time of our evaluation. The proposed lots will be accessed from 40 Avenue South, South 126 Street, or 41 Avenue South. The proposed six-lot subdivision and the approximate locations of the explorations accomplished for this study are shown on the Site and Exploration Plan, Figure 1. FIELD EXPLORATION The subsurface exploration program conducted for this study consisted of completing three test pit explorations across the site. Test pits were located in the steeper sloped portions of the site. The test pit explorations were completed to depths ranging from 13 to 15.5 feet below the existing ground surface. Ground surface elevations at the test pit locations were interpreted from the topographic information presented in Figure 1. Subsurface Conditions Fill was observed below the surface in the three test pits. The fill generally consisted of loose to medium dense silty sand with gravel. In test pit TP -1, wood and metal debris was observed at a depth of 3.5 feet. In addition, a thin (approximately 6 inch) layer of silty sand with gravel and burned organics was observed in test pit TP -1 at a depth of 5 feet. The thickness of the fill was observed to be approximately 5.5, 3.5, and 1.5 feet, in test pits TP -1, TP -2, and TP -3, respectively. Below the fill was medium dense to very dense weathered glacial till. The glacial till typically consisted of moist to wet, silty sand with gravel. Cobbles were occasionally observed. In test pit TP -3, the glacial till was coarser and consisted of sandy gravel from approximately 5.5 to 10.5 feet. The glacial till extended to the bottom of the test pits. The USGS map Geology of the Des Moines Quadrangle, Washington (Map GQ -159), dated 1962, shows the site as being mantled by ground moraine (till) of the Vashon drift. The soils observed in the test pits appear to be consistent with the USGS mapping. Soil descriptions presented in this report are based on the subsurface conditions observed at the specific test pit locations. Variations in subsurface conditions may exist between the exploration locations, and the nature and extent of variations between the explorations may not Zipper Zeman Associates, Inc. 19231 -36ty Avenue W., Suite B201 Lynnwood, Washington 98036 t7t6t a ,- .r......� ,.. ...a.4xxs5: !K't �M,�`.�tMlMM1.M"^.NwiW4R( +.+x ` fl'. ��Y.* �" �VI' f^>. ft �n' �> 1� ;4e:'kT/1!'.r:��.....aM^'KS'v arrj�p..tq;•r {..^^rc�^r.,• :9 -i k l.'.°= �K`. f to (425) 771 -3304 z re Li o.

If variations then appear, it may be necessary to reevaluate the recommendations presented in this report. Groundwater J -671 March 13, 2000 Page 3 Perched groundwater seepage was encountered at depths of 15, 8, and 4.5 feet in test pits TP -1, TP -2, and TP -3, respectively, at the time of exploration. The regional groundwater table was not encountered in the explorations. It should be noted that groundwater conditions and soil moisture contents are expected to vary with changes in season, precipitation, site utilization, and other on- and off -site factors. Given the relatively dense nature of the soils a few feet beneath the existing ground surface, near surface perched groundwater conditions should be expected to develop following periods of prolonged precipitation. CONCLUSIONS AND RECOMMENDATIONS We anticipate that the proposed development will utilize wood frame construction above reinforced concrete, cast -in -place foundations and concrete slab -on -grade floors. Based upon the subsurface exploration program, the project appears feasible utilizing conventional shallow foundation support. Sensitive Area Considerations The eastern portion of the subject site is classified by the City of Tukwila as a Class 2 area on the city's 1990 Sensitive Areas Maps. The Sensitive Areas Maps are on file at the Department of Community Development. Chapter 18.45 of the City of Tukwila Municipal Code, entitled Sensitive Areas Overlay, defines a Class 2 slope as follows: "Class 2 areas, where landslide potential is moderate, which includes areas sloping between 15% and 40 %, and which are underlain by relatively impermeable soils or bedrock." The drawing prepared by RN Parnell Company, dated 12/09/99, and our site reconnaissance indicate maximum slope inclinations in the center and western portions of the site between 20% and 40 %, with a small strip in Lot 5 (center of site) approaching 50 %. The subsurface exploration disclosed relatively impermeable glacial till soils at depths of 1.5 to 5.5 feet below existing grade. Based on this information, the overall Class 2 designation of the site appears appropriate, in our opinion. Our subsurface exploration, surface reconnaissance, and geologic literature review did not suggest the presence of any past instability or slope movement on the property. Fill typically consisting of silty sand with gravel was observed to depths ranging from 1.5 to 5.5 feet below the existing grade at the test pit locations. The underlying glacial till soils were encountered in a medium dense to very dense state.

The potential for shallow surface sloughing is also considered low, provided the loose fill is removed or recompacted to a more dense condition. The drainage conditions on the site will be improved by the connection and tightlining of runoff from impervious surfaces and footing drains/underslab drains to the storm drainage system. The proposed development is not expected to create a landslide or erosion hazard to the subject property or surrounding properties, in our opinion. A slope which appears to be inclined at approximately 50 to 60 percent is located along the southerly property line of Lots 3 and 4. We recommend that the proposed residential structures have a minimum setback of 40 feet from the top of this slope. Seismic Criteria Figure 164 in the 1997 Uniform Building Code classifies the subject site as being within Seismic Zone 3. Based on the subsurface conditions encountered at the site and published geologic literature, it is our opinion that Soil Profile Type S be used to describe the average soil properties within the upper 100 feet beneath the site. This designation describes soils that are considered very dense with a shear wave velocity of 1,200 to 2,500 feet per second, Standard Penetration Test values greater than 50, and an undrained shear strength greater than 2,000 psf. Soil liquefaction is a condition wherein loose granular soils located below the ground water table loose strength during the ground shaking associated with an earthquake. The soils encountered in our test pits consisted of 1.5 to 5.5 feet of loose to medium dense fill underlain by medium dense to very dense glacial till soils consisting of silty sand with gravel to sandy gravel. Slight perched groundwater seepage was encountered in the test pits, but the local groundwater table was not encountered in the explorations. Based on the grain size distribution of the site soils and the absence of a permanent groundwater table, we did not observe any contiguous layers of liquefiable soils on the project site within the depths explored, and liquefiable deposits are not anticipated at greater depths due to the glacially consolidated nature of the site. It is our opinion that the risk of damage due to soil liquefaction is low. Site Preparation J -671 March 13, 2000 Page 4 We anticipate that this project will require minor cut -and -fills to establish the building pad grades. Site preparation should include the removal of all existing fill, vegetation, root mass, organic soils, and any deleterious debris from building and paving areas, or those locations where "structural fill" is to be placed. Exposed soils following site preparation should consist of medium dense to very dense silty sand with gravel (glacial till). Localized areas of deeper organics, such as root systems, may be encountered within the project site and should likewise be removed. Any excavations that extend below finish grades should be backfilled with structural fill as outlined subsequently in this report. In our opinion, the topsoil is not suitable for reuse as structural fill and should therefore be exported from the site or used for landscaping purposes. 19231 — 36ty Avenue W., Suite 8201 Zipper Zeman Associates, Inc.

It will not be possible to successfully utilize on- site soils as "structural fill" if accumulated water is not drained prior to grading, or if drainage is not controlled during construction. Attempting to grade the site without adequate drainage control measures will reduce the amount of on -site soil effectively available for use, increase the amount of select import fill materials required, and ultimately increase the cost of the earthwork and foundation construction phases of the project After removal of existing fill, organics and other deleterious material, and prior to placement of structural fill, we recommend that foundation, floor subgrade, sidewalk and pavement subgrade areas, and areas to receive structural fill be proofrolled and compacted to a firm and unyielding condition in order to achieve a minimum compaction level of 95 percent of the modified Proctor maximum dry density as determined by the ASTM:D -1557 test procedure. Proofrolling should be accomplished with a heavy compactor, loaded double -axle dump truck, or other heavy equipment under the observation of a representative from our firm. This observer will assess the subgrade conditions prior to filling. The need for or advisability of proofrolling due to soil moisture conditions should determined at the time of construction. We recommend that a representative from our firm observe the soil conditions prior to and during proofrolling to evaluate the suitability of stripped subgrades. Earthwork may be difficult or impossible during periods of elevated soil moisture and wet weather due to the moisture sensitive nature of the silty site soils. Excavated site soils may not be reusable as structural fill depending on the moisture content and weather conditions at the time of construction. If soils are stockpiled for future reuse and wet weather is anticipated, the stockpile should be protected with plastic sheeting that is securely anchored. If on -site soils become unusable, it may become necessary to import clean, granular soils to complete wet weather site work. • Subgrade soils that become disturbed due to elevated moisture conditions should be overexcavated to expose firm, non - yielding, non - organic soils and backfilled with compacted structural fill. We recommend that the earthwork portion of this project be completed during extended periods of dry weather if possible. If earthwork is completed during the wet season, it may be necessary to take extra precautionary measures to protect subgrade soils. Wet season earthwork may require additional mitigative measures beyond that which would be expected during the drier summer and fall months. This could include diversion of surface runoff around exposed soils, draining of ponded water on the site, and collection and rerouting of groundwater seepage from upgradient on- and off-site sources. Once subgrades are established, it may be necessary to protect the exposed subgrade soils from construction traffic. Placing quarry spalls, crushed recycled concrete, or clean pit -run sand and gravel over these areas would further protect the soils from construction traffic.

Prior to placement, the surfaces to receive structural fill should be prepared as previously described. All structural fill should be free of organic material, debris, or other deleterious material. Individual particle size should be less than 6 inches in maximum dimension. Structural fill should be placed in lifts no greater than 8 inches in loose thickness. The structural fill should be compacted to at least 95 percent of the modified Proctor maximum dry density as determined by the ASTM:D -1557 test procedure in building areas and to a depth of 2 feet below the subgrade surface in pavement areas. Below a depth of 2 feet in pavement areas, the structural fill should be compacted to at least 90 percent of ASTM:D -1557. We recommend that a representative from our firm be present during grading so that an adequate number of density tests can be conducted as structural fill placement occurs. In this way, the adequacy of the earthwork may be evaluated as it proceeds. In the case of roadway and utility trench filling and wall backfilling in municipal rights -of -way, the backfill should be placed and compacted in accordance with current local codes and standards. Where the existing ground surface slopes more than 5H:1V beneath proposed fills, the fill should be keyed and benched in suitable native soils per the minimum requirements of UBC, Volume 1, Section 33.3.2, Preparation of Ground. We recommend that all benches be at least 8 feet wide. The suitability of soils for structural fill use depends primarily on the gradation and moisture content of the soil when it is placed. As the amount of fines (that soil fraction passing the U.S. No. 200 sieve) increases, soil becomes increasingly sensitive to small changes in moisture content and adequate compaction becomes more difficult, or impossible, to achieve. Generally, soils containing more than about 10 percent fines by weight (based on that soil fraction passing the U.S. No. 4 sieve) cannot be compacted to a firm, non - yielding condition when the moisture content is more than a few percent from optimum. The optimum moisture content is that which yields the greatest soil density under a given compactive effort. At the time of the limited subsurface evaluation, the site soils disclosed by the explorations appeared to have moisture contents at or above their optimum moisture content relative to their possible use as structural fill. However, soil moisture conditions should be expected to change throughout the year. Most of the site soils contain a significant fine- grained fraction. Consequently, use of the on -site soil as structural fill will require that strict control of the moisture content be maintained during the grading process. Selective drying of over - optimum moisture soils may be achieved by scarifying or windrowing surficial materials during extended periods of dry weather. Soils which are dry of optimum may be moistened through the Zipper Zeman Associates, Inc. 19231 - 36ty Avenue W., Suite B201 Lynnwood, Washington 98036 �tx (425) 771-3304 z w n: 00 No w J i wo u. • - a 1- w I o z 1— uj 00 o . .. oI- w w � IL. o W Z c o 0 z 6 Lot Short Plat on South L26 Street Tukwila, Washington application of water and thorough blending to facilitate a uniform moisture distribution in the soil prior to compaction. In the event that inclement weather or wet site conditions prevent the use of on -site soil or non - select material as structural fill, we recommend that a "clean ", free - draining pit -run sand and gravel be used. Such materials should generally contain less than 5 percent fines, based on that soil fraction passing the U.S. No. 4 sieve, and not contain discrete particles greater than 6 inches in diameter. It should be noted that the placement of structural fill is, in many cases, weather - dependent. Delays due to inclement weather are common, even when using select granular fill. We recommend that site grading and earthwork be scheduled for the drier months, if at all possible. Permanent Fill Slopes Permanent fill slopes should be constructed no steeper than 2H:1 V. If the slopes are exposed to prolonged rainfall before vegetation becomes established, the surficial soils will be prone to erosion and possible shallow sloughing Surficial repairs, such as armoring affected areas with quarry spoils, may be necessary until vegetation is established. Temporary and Permanent Cut Slopes Temporary slope stability is a function of many factors, including the following: J -671 March 13, 2000 Page 7 1. The presence and abundance of groundwater; 2. The type and density of the various soil strata; 3. The depth of cut; 4. Surcharge loadings adjacent to the excavation; 5. The length of time the excavation remains open. It is exceedingly difficult under the variable circumstances to pre - establish a safe and "maintenance -free" temporary cut slope angle. Therefore, it should be the responsibility of the contractor to maintain safe slope configurations since the contractor is continuously at the job site, able to observe the nature and condition of the cut slopes, and able to monitor the subsurface materials and groundwater conditions encountered. It may be necessary to drape temporary slopes with plastic or to otherwise protect the slopes from the elements and minimize sloughing and erosion. We do not recommend vertical slopes or unsupported cuts deeper than 4 feet if worker access is necessary. The cuts should be adequately sloped or supported to prevent injury to personnel from local sloughing and spoiling. The excavation should conform to applicable Federal, State, and local regulations. According to Chapter 296 -155, Part N, Excavation Trenching and Shoring, of the Washington Administrative Code (WAC), it is our opinion that the soils encountered at the site would be classified as Type B soils.. According to the Code, excavations less than 20 feet deep 19231— 36ty Avenue W., Suite B201 Zipper Zeman Associates, Inc.

We recommend that temporary cuts exposed to inclement weather be covered with sheet plastic to reduce the risk of erosion and destabilization. For medium dense to very dense native soils, or compacted structural fill, we generally recommend all permanent cut slopes be designed at a 2H:1 V inclination or flatter. Flatter permanent cut slopes should be used in the existing fill. It has been our experience that the permanent slopes steeper than 2H:1V will tend to ravel and slough to a flatter inclination over time. In addition, with the steeper slopes, topsoil erodes readily and it is more difficult and takes longer to establish vegetation for slope protection. Shallow Foundations All footings should be founded on the medium dense to very dense native soils, or on compacted structural fill which extends down to the medium dense to very dense native soils. Footings should not be founded on or within loose or disturbed native soil or fill unless it has been evaluated and approved by the geotechnical engineer. Continuous or column footings may be designed for a maximum allowable bearing pressure of 2,000 psf. A one -third increase in this bearing pressure may be used for short-term wind or seismic loading. For building and retaining wall foundations, we recommend using an allowable base friction value of 0.35 and a maximum allowable passive resistance of 225 pcf for those foundations embedded at least 18 inches below finish grades. Exterior footings should extend at least 18 inches below adjacent grade for frost protection, while the interior footings should extend at least 12 inches below adjacent grade. We also recommend that all foundations be set back at least 10, 15, and 25 feet horizontally from the face of any slope which is steeper than 20, 30, and 40 percent, respectively. This distance should be measured horizontally from the side of the footing to the slope face. We recommend that all continuous and isolated footings be at least 15 and 18 inches in width, respectively. We estimate that the total settlement of foundation members founded within the medium dense to dense native soils or on compacted structural fill may approach 1 inch. Differential settlement of foundations founded within the same soil type could approach 1/2 inch. Settlements would occur elastically as the loads are applied. If possible, we recommend that the foundation elements be placed within the same soil type to minimize the magnitude of possible differential settlement. It should be noted that differential settlement could approach the total settlement values if adjacent footings are founded on different bearing strata. At the time this report was written, final design information regarding foundation or floor grades was not available. Consequently, we cannot comment conclusively regarding the anticipated bearing conditions of foundations at specific locations. Foundation settlement is oftentimes a function of the condition of the footing excavation subgrade. Footing excavations should be free of loose or soft soil, slough, debris, or water prior to pouring footing concrete. The high moisture sensitivity of the silty site soils may require that the footing excavations be covered with a lift of crushed rock or a lean concrete "mud mat" to minimize Zipper Zeman Associates, Inc. 19231 — 361y Avenue W., Suite B201 Lynnwood, Washington 98036 (425) 771-3304 •., vKvy •er.. ee^+r'.•eawx -- •. w+, tw, >.: �,- x�...>,• t- z".:::� r.•... •i+v.' +m!7'r ;vrY'Ya; ^:FtYr,°E'' "f++fi tF+ .M1!AC;ftitefi`t>!f '�Np �n.•..> z w re 00 U) CD J = w • 0 2 g< ��. w � z �— w w U� 0 Y t— w - I— LL W z to o • z 6 Lot Short Plat on South .26 Street Tukwila, Washington disturbance of the bearing surface during construction in wet weather.

The o drain should consist of a minimum 4 -inch diameter perforated pipe embedded in at least a 18- cn W inch wide envelope of clean, free - draining granular material, such as pea gravel. Footing drains should be directed toward appropriate storm water drainage facilities and not onto adjacent co u. slopes. Roof drains should not be connected to the footing drains 1Ji O Slab -On -Grade Floors < = Slab -on -grade floor subgrades should be prepared in accordance with the site preparation recommendations presented above. All slab-on-grade floors should be founded on the medium Z '— I-- dense to very dense native soils, or on compacted structural fill extending down to the medium o dense to very dense native soils. Slab -on -grade floors should not be founded on or within loose 2 or disturbed native or fill soil unless it has been evaluated and approved by the geotechnical o N _ engineer. o w w We recommend that slab -on -grade floors be underlain by a minimum 4 -inch thickness of 1 F coarse sand and gravel to provide uniform support and act as a capillary break. LL z ui In floor slab areas where moisture sensitive floor coverings are planned, an impermeable o . membrane (e.g. polyethylene sheet) should be placed directly beneath the floor slab to act as a z vapor barrier. The impermeable membrane should be protected by two inches of fine, moist sand placed both above and below the membrane. The sand cover will provide protection for the membrane and will promote uniform curing of the concrete slab. The sand cover should be moistened and tamped prior to slab placement. Depending on final building configurations and floor grades, it may be necessary to provide undersiab drainage for the new houses. This issue should be evaluated by our firm once fi al building configurations and floor grades have been established. Backfilled Walls 19231— 36ty Avenue W., Suite B201 Zipper Zeman Associates, Inc. Lynnwood, Washington 98036 J -671 March 13, 2000 Page 9 All backfill placed behind walls or around foundation elements should be placed in accordance with our recommendations for structural fill. The following recommended earth pressures, presented as equivalent fluid weights, are based on the assumption of a uniform level backfill with no buildup of hydrostatic pressure behind the wall. To minimize lateral earth pressures and prevent the buildup of hydrostatic pressures, the backfill within 24 inches of the (425) 771 -3304 6 Lot Short Plat on South 126 Street Tukwila, Washington wall should contain less than 5 percent fines, based on that portion passing the U.S. No. 4 sieve, coupled with a perforated pipe drain placed at the base of the wall backfill, similar in configuration to that described for the perimeter footings. The upper 1 -foot of the wall backfill should consist of a low permeability silty soil and be sloped away from the wall in order to reduce the potential for surface water infiltration behind the wall. If the backfilled walls are structurally restrained from lateral movement at the top, we recommend that they be designed for an "at- rest" equivalent fluid weight of 55 pounds per cubic foot(pcf). If the top of the wall is free to move laterally in an amount equal to at least 0.1 percent of the wall height during placement of backfill soils, they may be designed for an "active" equivalent fluid weight of 35 pcf. Surcharges due to sloping ground, adjacent footings, vehicles, construction equipment, etc., must be added to these values. The above equivalent fluid pressures assume that the backfill is compacted to approximately 90 to 92 percent of the modified Proctor maximum dry density. Additional compaction adjacent to the wall will increase the earth pressure, while a lesser degree of compaction could result in post construction settlements. Utility trenches constructed on the site may act as french drains by intercepting perched groundwater seepage. Some of these utility trenches may lead to the proposed houses and subject them to additional moisture. Therefore, it is highly recommended that the wall backfill consist of free - draining aggregate as recommended herein. Additionally, footing drains should be constructed at elevations below all wall penetrations and preferably at footing elevations. Construction Considerations The native soils that will be exposed upon completion of stripping contain a significant percentage of fine- grained particles. These silty soils are susceptible to disturbance, particularly when wet. We recommend that the contractor make every effort to minimize disturbance of stripped surfaces. These efforts may include directing surface water away from open excavations and • the placement of a crushed rock or concrete mud slab surface in the footing trench excavations. If site work is accomplished in wet weather, the placement of clean sand and gravel below paved areas would promote future drainage and improve subgrade support. In addition, vehicle traffic over wet subgrades or prepared areas should be minimized. Application of these measures will reduce the likelihood of additional overexcavation of disturbed soils and associated costs for export and import will be reduced.

Under the circumstances, it is recommended that we be provided the opportunity for general review of the project plans and specifications in order to confirm that the recommendations and design considerations presented in this report have been properly interpreted and implemented into the project design package. The integrity and performance of the foundation systems at this site depend greatly on proper site preparation and construction procedures. Field judgement by a qualified engineer will be necessary in order to determine the adequacy of the site drainage and foundation support systems. Therefore, because of our familiarity with the site soils, we recommend that Zipper Zeman Associates, Inc. be retained to provide geotechnical engineering services during the earthwork and foundation construction phases of the project. If variations in the subsurface conditions are observed at the time of construction, we would be able to provide additional geotechnical engineering recommendations to the contractor and owner in a timely manner as the project construction progresses. If other engineering or soil inspection firms are used during earthwork, we recommend that the transfer of responsibility be completed in accordance with Volume 1, Section 3317.9 of the Uniform Building Code. We appreciate this opportunity to be of service to you, and would be pleased to discuss the contents of this report or other aspects of the project with you at your convenience.

CITY OF TUKWILA PUBLIC WORKS PROJECT REVIEW COMMENTS Project Name: Riverhills Lot A 4031 S. 126 St. File #: b2000 -038 Date: 05.10.00 Reviewer: L. Jill Mosqueda, 1. Your Technical Information Report was very well done. It had it all in one place, making it easier to review. Thanks. 2. The City Of Tukwila Public Works Department has the following comments regarding your application for the above permit. Please contact Jill Mosqueda at (206) 433 -0179, if you have any questions regarding the following comments. 3. Please return the enclosed redlined plans with your revision submittal. 4. The water improvements either must be constructed before we issue this permit or they must be constructed as part of this permit. 5. Please refer to the enclosed copy of the preapplication checklist for driveway access and other requirements. 6. I enclosed copies of three residential driveway details. Please indicate on the plans which you prefer. It is very helpful to place a copy of the detail on the plans. 7. I enclosed copies of infiltration trench details. Please show the detail and the material specifications on the plan sheet. 8. To help you out with the improvements for the short plat, I enclosed details and specifications for typical roadway section and for street lighting. Hope these help with the 2- street full- improvements for S. 126 St. I think you need to add trees on the south side also. That would be in the preapplication checklist from planning.

O z SUMMARY OF EROSION PREVENTION AND SEDIMENT CONTROL COVER REQUIREMENTS A condition of the your permits is that the erosion prevention and sediment control be installed as the first order of business. Keystar has installed erosion silt fence in an in an inappropriate application and has not provided temporary cover for the nearly two acres of disturbed soils. The following summarizes the City's standards for cover measures: May 1 through September 30, temporary cover measures shall be installed on ALL areas left undisturbed for more than seven days. October 1 through April 30, temporary cover measures shall be installed on ALL disturbed areas left unworked for more than TWO DAYS. These requirements may be relaxed at the City's discretion, depending on site topography and other conditions. At all times, any disturbed areas left unworked for more than 30 days shall be seeded. Wet season requirements — At a minimum, the ESC plan and plan notes shall provide the following for work which will occur from October 1 through April 30: • Install temporary cover measures on all areas which will remain unworked for more than TWO DAYS and on stockpiles and steep cut and fill slopes. • Retain onsite a quantity of cover measures materials sufficient to cover all disturbed areas. • By October 8, temporarily seed and mulch all areas that will be unworked during the wet season. • Mulch all seeded areas. • Stabilize all construction traffic areas, unless already graveled. SUMMARY OF CITY ESC REQUIREMENTS The erosion prevention and sediment control (ESC) plan shall be designed in accordance with the current edition of the King County Surface Water Design Manual. The plan shall provide information for temporary erosion prevention and sediment control during all phases of construction and also shall provide Ilk permanent stabilization for disturbed areas.

ESC MAINTENANCE 1. Failure to maintain ESC measures in accordance with the approved maintenance schedule may result in the work being performed at the direction of the Director and assessed as a lien against the property where such facilities are located. 2. During the life of the project, the Applicant/Owner shall maintain in good condition and promptly repair, restore, or replace all grade surfaces, walls, drains, dams, structures, vegetation, erosion and sediment control measures, and other protective devices in accordance with approved plans. 3. The Applicant/Owner shall monitor the downstream drainage features, and shall, with City approval, remove all sediment deposition resulting from project - related work. 4. The City shall assume maintenance and operation responsibilities for all ESC measures located within public easements and rights -of -way, following final acceptance of such facilities by the City. ESC DURING CONSTRUCTION 1) As the first order of business, the Permittee shall install erosion prevention and sediment control measures per the ESC. Install the downstream temporary ESC measures before any site disturbance occurs. Before the temporary measures are removed, install and establish the upstream permanent ESC measures. 2) The Permittee shall at all times protect sensitive areas, their buffers, and adjacent private properties and public rights -of -way or easements from damage during land altering operations. The Permittee shall restore, to the standards in effect at the time of the issuance of the permit, sensitive areas, their buffers, and public and private properties and improvements damaged by the Permittee's operations. 3) Permittee shall arrange for and comply with the following: • Notify the Public Works Department within 48 hours following installation of ESC measures. z ~ w U: CO 0 U o; cow * J =, H w o, g a ` S2 a z �; o w Ua 'o co , w w' AL-3. w z: 0 z • Obtain permission in writing from the Public Works Department prior to modifying the ESC plan. • Maintain all road drainage systems, storm water drainage systems, control measures and other facilities as identified in the ESC plan. • Repair any siltation or erosion damages to adjoining properties and drainage facilities. • Inspect according to the approved ESC inspection schedule, and make needed repairs immediately. so ,4[R'.3itiu'eti Table 2 Matrix of temporary and permanent erosion control measures and estimated effectiveness ratings.

Designation assumes correctly installed: E= Excellent, M= Moderate, P =Poor Chapter 1 Erosion Control Page 15 Z Dust Control Preventative measures to minimize the wind transport of soil, prevent a traffic hazards and reduce sediment transported by wind and deposited in water resources. Applications When exposed soils are dry to the point that wind transport is possible and roadways, drainage ways or surface waters are likely to be impacted. Advantages • Reduces movement of soil to offsite areas. Disadvantaqes • Over watering, when water is used as dust control, may cause erosion. Design Criteria • Dust control is covered in the 00280 Supplemental. The designer can provide project- specific dust control specifications in the 00280 Special Provisions. • Dust control measures include: * Temporary stabilization practices such as temporary and permanent seeding, temporary mulching and erosion control blankets. * Sprinkling exposed areas with water. * Installing construction entrances and stabilizing construction haul roads. * Application of calcium chloride. Buffer Zone A buffer zone consists of an undisturbed area or strip of natural vegetation or an established suitable planting which reduces erosion and runoff. Applications • Between disturbed areas and streams or other water bodies. • Along natural swales and at wetlands. Advantages • Provide habitat. • Reduces velocity and quantity of runoff. • Provide visual screening. • Low maintenance. Chapter 1 Erosion Control Page 16 1 Disadvantages • Requires keeping all construction equipment, debris and soils out of the natural areas. • Extensive buffers can increase project costs. Special Considerations • Constrains work area and equipment movement. • Requires the Inspector to fence or flag the clearing limits. • Requires the Inspector to fence or flag outside tree and shrub driplines. Design Criteria • Preserve natural vegetation in clumps, blocks or strips. • Preserve natural vegetation on unstable, sleep slopes. • Vegetative buffer zones for streams, lakes or other water ways should be 30 m wide on each side of the feature. The width can increase depending on other onsite conditions, existing vegetative conditions and erosion potential. Maintenance • Inspect flagging and fencing frequently and repair as needed. Preserve Natural Vegetation Preserving vegetation minimizes soil exposure and provides aesthetic benefits. Applications • Flood plains, wetlands, stream banks, steep slopes and other areas where erosion controls would be difficult to install and maintain. Advantages • Helps reduce soil erosion and runoff while beautifying an area. • Saves landscaping costs, provides areas for wildlife, and provides visual screening. • Helps maintain water temperature. Temperature moderation is especially important when detention ponds drain to salmonid-bearinq streams. • Retains existing shade and cover habitat. Disadvantages • Retaining older trees could create a safety hazard. • May constrict area available for construction activities. Special Considerations • Requires coordination with Environmental Services Unit, Landscape Unit and the construction Project Manager's office. • Requires the Inspector to fence or flag the clearing limits. Chapter 1 Erosion Control Page 17 • Requires the Inspector to fence or flag outside tree and shrub driplines. Design Criteria • Contact the Landscape Architect when determining what to save and how to save it. • Vegetation can be preserved in natural clumps or as individual trees, shrubs and vines. • Clearly flag or mark the ground disturbance limits outside the dripline of preserved trees. • Protect vegetation from: * Construction equipment injury above or below the ground level. Injury occurs from scarring, cutting roots, or compaction. * Grade changes which affect the plants' ability to obtain air, water or minerals. Placing a layer of gravel and a the system over the roots before a major fill allows air and protects the plant from the fill. * Root exposure. Terracing the area around the plant, or leaving the plants on an undisturbed mound can increase the plants' survival chances. * Damage caused by excavations for tile, water and sewer lines. Maintenance • Inspect and repair flagging or fencing. • Re -cover and /or seal exposed plant roots. Temporary and Permanent Seeding A well- established vegetative cover is one of the most effective methods of reducing erosion. Applications • On disturbed areas that require seeding either because the area has reached final grade (permanent seeding) or because the area will remain unworked from 2 to 12 months (temporary seeding). Refer to the 00280 Supplemental for soil exposure limitations and seeding dates. • In vegetation -lined channels, seed and then protect with a net or blanket. • In retention /detention ponds. Advantages • Prevents erosion and also traps sediment. • Improves appearance of the site. • Provides excellent stabilization. • Relatively inexpensive erosion control measure. Chapter 1 Erosion Control Page 18 Disadvantages • Needs sufficient time for seed to establish. • May require mulch or other cover. • May require fertilizer and lime to establish on poor soils. • May require irrigation. Desian Criteria The following discussion presents general information regarding seeding, bed preparation, mulching and fertilizing. See the 00280 Supplemental for specific seeding requirements. Seed • Generally, the best time to permanently seed is early spring or late fall depending on site conditions. Mulching and irrigation may be required for areas seeded during the hot summer months. • Seed applied during the winter may take several months to develop a dense ground cover due to cold temperatures. The application and maintenance of mulch is critical for winter seeding. • To prevent seed from being washed away, confirm installation of all required surface water control measures. Seedbed • Prepare a firm but not compacted seedbed. Roughen slopes steeper than 1:3. The typical method is track - walking (driving a crawling tractor up and down the slope) creating cleat imprints parallel to the slope contours. Seed Mixes • Provide project - specific seed mixes and application rates in the 00280 Special Provisions. Fertilizer • Slow- release fertilizers are more efficient and have fewer environmental impacts.. Areas being seeded for final landscaping may require soil tests to determine the exact type and quantity of fertilizer needed to prevent the over - application of fertilizer. Use non - phosphorus fertilizer on disturbed areas near water bodies and wetlands. • The addition of stockpiled topsoil or compost reduces the need for fertilizer and improves the overall soil quality. • Provide project- specific application rates in the 00280 Special Provisions. Mulch • Required for seeding slopes greater than 1:3. • Required for seeding during the wet season. • May be required during the dry season if: * Grass growth is expected to be slow, Chapter 1 Erosion Control Page 19 z Z ` w W � Co N CO w: W N LL` w g Q = 1- Z �. 1- o w 2 O N .o ff . = V, ai z U 0 z * The soils are highly erodible, * There is a water body close to the disturbed area, or * Significant precipitation is anticipated before the grass will provide effective cover. • Can be applied on top of the seed or applied with the seed during hydroseeding. Hvdroseed • Hydroseeding requires a mulch tracer as a visual aid during application. • On slopes 1:1.5 and steeper, hydroseeding requires and tackifier. • During the dry season, hydroseeding with wood fiber mulch is adequate. • During the wet season, double the application rate to compensate for more rapid breakdown of the mulch. Maintenance • Reseed areas that fail to establish adequate cover within specified time. If reseeding is ineffective, use an alternate method, such as sodding or nets /blankets. • Reseed and protect with mulch any areas affected by erosion. If the erosion is caused by concentrated runoff, fix the runoff problem and then reseed and mulch the area. Mulch Mulching soils provides immediate temporary protection from erosion. Mulch also enhances plant establishment by conserving moisture, holding fertilizer, seed, and topsoil in place, and moderating soil temperatures. There are many varieties of mulch, only the most common types are discussed in this section. Applications • On areas which can't be seeded or are otherwise unfavorable for plant growth. • As a cover for seed during the wet season and during the hot summer months. • As temporary stabilization on bare soils exposed by construction activities. Refer to the 00280 Supplemental for specific requirements. Advantages • Provides instant protection. • Conserves moisture. • Does not require removal. • Allows vegetation growth through the mulch. • In all seasons, protects temporary and permanent seeding from heat, moisture loss and transport due to runoff and provides effective cover for seeding during the dry season. Chapter 1 Erosion Control Page 20 41416' z r w U0 co o co uw w = J • w w O` J. u_ . _. z � � z � D o; O N : 0 F- uJ u' O u UN z ti Disadvantages • Must be applied at the specified thickness. • Thick mulches can delay germination. • Can be blown or washed away if not adequately secured. Design Criteria • Divert concentrated runoff from mulched slopes. • Specific material and application criteria are included in the 000280 Supplemental. The following discussion contains general information regarding mulches. Organic Mulches • Straw mulch provides immediate protection lasting approximately three months. Straw can be spread by hand or by machine and may require anchoring for wind protection. Common anchoring methods include crimping, disking, rolling or punching into the soil; covering with netting; spraying with a tackifier; or keeping it moist. Straw mulch is commonly used in Eastern Oregon in conjunction with seeding. • Corn Stalks, which decompose slowly and are resistant to windblow, should be shredded into 100 to 150 mm lengths. • Wood chips are suitable for areas that will not be closely mowed and areas around ornamental plantings. Chips decompose slowly and require nitrogen application to prevent nutrient deficiency in plantings. Both wood and bark chips tend to wash down slopes greater than 6 %. • Wood cellulose, grass straw cellulose and paper fiber products are commonly used in western Oregon in a hydroseed slurry mix containing fertilizer. In Eastern Oregon the hydroseed slurry is used in conjunction with straw mulch to add protection from the sun. The combination of hydroseed slurry and straw mulch is well suited to steep slopes, critical areas and severe climate conditions. Wood fiber hydro - slurries, not containing seed or fertilizer, are used to tack straw mulch. • Manure mulches should be well -aged and are not suitable for use near water bodies. • Leaf compost, available in some areas of the state, is suitable for flat areas and steep slopes. Chemical Mulches Synthetic, spray -on mulches and soil binders can seal the soil surface, increasing erosion, and may cause adverse effects on water quality. Therefore, they are not recommended for use as a mulch. Chemical mulches may serve as tacking agents. Chapter 1 Erosion Control Page 21 z 00 CO 0 CO w 9 cn w. wo g a a I- 11 J Z �. I0 - U m o = 0 I - : w w L o ui z ULo. 0 z Maintenance • Maintain the thickness of the cover. • Remulch and /or protect with a net or blanket any areas that experience erosion. If the erosion problem is drainage related, then fix the drainage problem and remulch the eroded area. Sod Establishes permanent turf for immediate erosion protection and stabilizes drainageways. Applications • Disturbed areas requiring short -term or Tong -term cover. • Disturbed areas requiring immediate vegetative cover. • Waterways carrying intermittent flow (except biofiltration swales) and requiring immediate stabilization or aesthetic mitigation. Advantages • Provides immediate protection which is effective and aesthetically pleasing. • Provides high density vegetation which is superior to a recently seeded area. • Placement can occur any time that soil moisture is adequate and the ground is not frozen. Disadvantages • Expensive. • Difficult to find sod free of weeds. • Irrigation may be required if installed in summer. • Difficult to.mow if installed on slopes steeper than 1:3. • Installations in grassed waterways may roll up if not anchored or drained properly. 'Design Criteria • Use sod which is weed free, has uniform thickness (approximately 25 mm thick) and dense root mat for mechanical strength. • Generally inappropriate for bioswales. Sod can be used for lining ditches to prevent erosion, but will provide little water quality benefit during the wet season. • The following steps are general recommendations for sod installation. Refer to ODOT's Standard Specifications for specific installation criteria. • Shape and smooth the surface to final grade in accordance with the approved grading plan. • Fertilize as per supplier's recommendations. Some jurisdictions may require a non - phosphorous fertilizer near water bodies and wetlands. Chapter 1 Erosion Control Page 22 z UO U p ow: • u. w O. u. a. z_ z z ►-. ▪ m ui F- U • w z o ff . z • Work lime and fertilizer into soil 25 -50 mm deep and smooth the surface. • Lay sod strips perpendicular to the direction of water flow, beginning at the lowest area to be sodded. Wedge strips securely into place and square the ends of each strip to provide for a close, tight fit. Stagger joints at least 300 mm. Staple sod onto 1:3 and steeper slopes. • Roll the sodded area and irrigate. • When sodding is carried out in alternating strips or other patterns, seed the areas between the sod immediately after sodding. Maintenance • Inspect sodded area frequently. • Retack, resod or reseed as necessary. • If it is impossible to establish a healthy ground cover due to frequent saturation, instability, or some other cause; remove the sod, seed the area with an appropriate mix, and protect with a net or blanket. Erosion Control Blankets Nets are strands of material woven into an open, but high - tensile strength net; for example, jute net). Mats are strands of material that are not tightly woven, but instead form a layer of interlocking fibers, typically held together by a biodegradable or photodegradable netting; for example, excelsior (wood fiber) or straw blankets. Blankets generally have lower tensile strength than nets, but cover the ground more completely. Coir (coconut fiber) fabric comes as both nets and blankets. Geotextile may also serve as blankets. Figure 4 Slope and ditch application of erosion control matting. Chapter 1 Erosion Control Page 23 Applications • On disturbed areas that require cover measures for more than 30 days. • For permanent stabilization of slopes 1:2 or steeper and with more than 3 m of vertical relief. • For permanent reinforcement of turf to protect drainageways during high flows. • For permanent stabilization of channels, possibly providing a cost - effective, environmentally preferable alternative to riprap. • For drainage ditches and swales. The appropriate netting or blanket applied to drainage ditches and swales can protect bare soil from channelized runoff while vegetation is established. • On steep slopes and in channels to prevent erosion and hold seed and mulch in place. Advantages • Do not generate high - velocity runoff and, therefore, offer temporary slope protection which is superior to plastic sheeting. • Capture a great deal of sediment due to their open, porous structure. • Usually easy to install. Disadvantages • Correct installation is critical to the effectiveness of these products. Good ground contact during installation prevents runoff concentrating under the blanket and causing significant erosion. Design Criteria • Apply as temporary slope stabilization according to 00280 Supplemental. • Organic blankets (excelsior, jute and coir) biodegrade and are useful for applications requiring stabilization for up to three months. Use organic blankets, which retain moisture and provide organic matter to the soil, for slope protection and short -term waterway protection and to improve the speed and success of revegetation. * Use jute netting in conjunction with mulch in order to prevent erosion that could result from the net's open structure. * Excelsior, woven straw, and coir blankets may be installed without mulch because they provide complete surface protection. • Synthetic mats are made from non - biodegradable material and will remain in place for years. Use purely synthetic blankets for Tong -term stabilization of waterways. * Turf Reinforcement Mats (TRM) are made from polymer nettings or monofilaments formed into a mat. TRMs protect seed and increase germination and also acts as part of the root structure; giving the turf higher strength. * Erosion Control and Revegetation Mats (ECRM), composed of heat -fused monofilaments or monofilaments stitched between netting act as permanent mulch. ECRM allow growth through the mat. f Chapter 1 Erosion Control Page 24 z tif 00 w Lux J � u. wo g a (1? d ; � z � � z ,-. n 0 o � o - U 'L-0 w z 0 - . o . z • Ditch or swale applications: * Lengthwise overlap Min. 100 mm * Crosswise overlap Min. 150 mm * Avoid joining material in center of ditch or swale. • Slope application * Lengthwise overlap Min. 150 mm * Crosswise overlap Min. 50 mm * At top of slope, entrench material in a 150 mm X 150 mm trench and staple at 0.3 m intervals. * At bottom of slope, turn material under 100 mm and staple at 0.3 mm intervals. * On slopes flatter than 1:3, rolls can be placed in horizontal strips. Maintenance • Inspect periodically, especially following severe storms. • Repair any damaged areas of the net or blanket and staple into the ground any areas not in close contact with the ground surface. • If erosion occurs repair and protect the eroded area. Provides immediate, short -term protection to slopes and disturbed areas which cannot be mulched. There have been many problems with plastic sheeting, usually attributable to poor installation and maintenance. Use alternatives to plastic covering whenever possible.

Chapter 1 Erosion Control Page 26 Aggregate Construction Entrance A stabilized aggregate pad, placed at construction site ingress /egress locations, which reduces the amount of sediment transported onto paved roads by vehicles or runoff. Figure 6 Typical aggregate construction entrance detail. Applications • Wherever traffic will be leaving a construction site and traveling on paved roads or other paved areas located within 30 m of the site. Advantages • Reduces traffic hazards caused by debris on public roadways. • Reduces sediment on roadways which can wash into the storm sewer system. Disadvantages • Only effective if erosion and sediment control employed elsewhere onsite. • Only works if installed at every location where construction traffic leaves the site. .Design Criteria • Minimum length: 15 m for drainage areas having less than 0.4 hectare of exposed soil. 30 m for drainage areas having more than 0.4 hectare of exposed soil.

F O Construction Road/Parking Area Stabilization Stabilized parking areas and on -site vehicle transportation routes reduce erosion caused by construction traffic or runoff. Applications • Permanent or temporary roads or parking areas used by construction traffic. Advantages • Reduces onsite erosion, dust and off -site tracking of soils. • Can speed and enhance efficiency of onsite work. Disadvantages • Temporarily stabilized construction roads can be expensive to install and maintain. Design Criteria • Road and parking area stabilization may not be necessary during the dry season (unless dust is a concern) or if the site is underlain by coarse - grained soils. • ODOT usually leaves temporary road locations and construction criteria to the contractor's discretion. The following is general information regarding road and parking stabilization: • Stabilize roads and parking areas immediately after initial grading. • Whenever possible, construction roads and parking areas should be placed on firm, compacted subgrade. • Temporary road gradients shouldn't exceed 15 percent. • Grade roadways to encourage sheet flow runoff to a roadside ditch or to a heavily vegetated area, except vegetated wetlands or landscaped areas, with a well- developed topsoil and at least 15 m of vegetation to treat the sheet flow runoff. Treating sheet flow runoff from temporary roads is preferred to using a sediment pond or trap. • Immediately following grading, apply crushed rock, gravel base or crushed surfacing base course. A course of asphalt- treated base (ATB), cement or calcium chloride may also be used. • Install fencing, if necessary, to limit vehicle access to stabilized roads and parking areas. Maintenance • Add crushed rock, gravel base, as required to maintain a stable driving surface and to stabilize any eroded areas.

Applications • On any slope where a temporary or permanent measure is needed to convey runoff to avoid erosion. Advantages • Effective method of conveying water down steep slopes. • Reduces or eliminates erosion. • Easy installation and little maintenance. Disadvantages • Drain can be under - designed or incorrectly located. • Area cleared for drain installation requires stabilization to prevent erosion occurring under the pipe. • Outfall systems constructed of pipe segments which are banded and /or gasketed together have developed leaks causing erosion and failure of the system. Failures on erodible or steep slopes can cause downstream sedimentation or even mudflows. Chapter 1 Erosion Control Page 30 M w UO ,o, W= u.

Estimate pipe diameter from the following table. Table 3 Slope Drain Sizes. • Consider using continuously fused, welded or flange - bolted mechanical joint systems with proper anchoring or HDPP (high density polyethylene pipe) for outfalls on steep slopes. • Show the entrance sloped toward the pipe inlet. • At the inlet, show interceptor dikes that are at least 0.3 m higher at all points than the top of the inlet pipe and placed to direct water into the pipe. • If the pipe slope drain will convey sediment -laden runoff, direct the runoff to a sediment retention facility. If the runoff is not from a disturbed area or is conveyed from a sediment trap or pond, convey the runoff to a stabilized discharge point. • Energy Dissipation - Plunge pools or riprap -lined stilling basins prevent most scour problems at outfalls. Consider site conditions to determine if a more complex energy dissipater may be required. Consult ODOT's FHWA's Hydraulic Design of Energy Dissipaters for Culverts and Channels as needed. • The special provisions and the typical detail should include the following installation directions: 1. Minimize disturbance during installation. In some circumstances this requires HDPP installed by hand. 2. Immediately stabilize any area disturbed during installation or maintenance. 3. Securely connect the standard flared end section at the entrance to the slope drain, using watertight connecting bands. 4. Securely fasten together the slope drain sections with gasketed watertight fittings, and securely anchor the sections into the soil. 5. Stabilize the area below the outlet following the energy dissipater. Chapter 1 Erosion Control Page 31 Maintenance • Regularly check the inlet and outlet points, especially following heavy rains. If there are signs of undercutting or water is going around the point of entry, reinforce the head wall with compacted earth or sand bags. • Regularly check at connection points for signs of erosion. Tighten fittings and repair erosion as needed. • Immediately repair and install appropriate protection if erosion occurs at the outlet. Interceptor Dike and Interceptor Swale A ridge of compacted soil or a Tined swale with vegetative lining located at the top, base or somewhere along a sloping disturbed area. The dike or swale intercepts and conveys smaller flows along low- gradient drainage ways to larger conveyances such as ditches or pipe slope drains or to a stabilized outlet.

Applications • Install above a disturbed slope to intercept runoff and reduce runoff volume on the disturbed area. • Install below a disturbed area to divert runoff to a sediment trapping device. Chapter 1 Erosion Control Page 32 • Install across a disturbed slope to reduce velocity. Advantages • Provides a practical, inexpensive method to divert runoff. • Can handle flows from large drainage areas. • Use on -site material and equipment to construct. Disadvantages • If improperly constructed, can contribute to erosion caused by concentrating the flow. • High flow velocity can damage vegetation. Design Criteria • Refer to Table 3 Dike Design Criteria and Table 4 Swale Design Criteria. • Install the dike and /or swale horizontally at intervals across a disturbed slope. Space horizontal interceptor dikes and swales according to Tables 3 and 4. • For slopes of erodible soils, steeper than 1:2 with more than 3 m of vertical relief, construct benches or shorten distance between dikes or swales. • If the dike or swale intercepts runoff from disturbed areas, discharge the runoff to a stable conveyance that routes the runoff to a sediment trap or basin. • If the dike or swale intercepts runoff that originates from undisturbed areas, discharge the runoff to a stable conveyance that will route the runoff downslope of any disturbed areas and release the water at a stabilized outlet. Maintenance • Immediately repair damage resulting from runoff or construction activity. • If the dike or swale regularly overflows, increase the capacity and /or frequency of the dikes /swales. • Inspect and repair as necessary after every major storm. • Minimize construction traffic over temporary dikes and swales.

Advantages • Relatively inexpensive method of sediment control. Disadvantages • Effective approximately 3 months. • Misuse or incorrect installation can contribute to sediment loading. • Difficult to tell if bales are properly installed. • Straw bale barriers have not performed as effectively as originally expected. There are three major reasons for such ineffectiveness: 1. Improper applications; installations in drainageways and swales where high water volumes and velocities destroyed effectiveness. 2. Improper placement and /or installation has allowed undercutting and end - flow. 3. Inadequate maintenance which can reduce effectiveness of sediment removal anywhere from 16% to 57% in one month.

Chapter 1 Erosion Control Page 43 Inlet Protection Prevents coarse sediment from entering storm drainage systems by filtering runoff and retaining sediment before it reaches a drainage inlet or storm sewer system. There are many options and variations of inlet protection available. WIRE MESH GEOTEXTILE Figure 15 Inlet protection applications. Applications • At inlets which are ready for use before completion of final stabilization and which receive runoff from drainage areas less than 4000 m (0.4 hectare) in size. • At storm drain inlets downslope and within 150 m of a disturbed area or construction entrance. Advantages • Prevents sediment from entering the storm drain system and clogging it. • Reduces amount of sediment leaving the site. Disadvantages • May result in ponding of water above the catch basin. • Sediment removal may be difficult under high -flow conditions. • May result in a traffic hazard. • Short- circuiting of flow may occur if not properly installed. • Useful only for low flows having low sediment loading.

Filter fabric Applications • Drainage areas which are 2 hectares and smaller. • Sites in proximity to salmonid streams, wetlands, or phosphorus- sensitive waterbodies. • Sites where major clearing and grading is likely to occur during the wet season. • Sites with downstream erosion or sedimentation problems. • Downslope of disturbed areas. Combining with Permanent Drainage Facilities 0 If a project includes a permanent storm water retention /detention pond, the rough - graded or final - graded facility could function as a trap during construction. Design features of the permanent structure, such as surface area, retention time Chapter 1 Erosion Control Page 46 and outlet control, should meet the design requirements of the temporary facility. Completion of the permanent facility should occur only when all upstream control structures are in place and stabilization of contributing drainage areas is complete. 0 If a project includes an infiltration facility, the roughly excavated facility could be z used as a trap or basin providing the facility provides the surface area and h retention time required by the trap or basin. Excavate the sides and bottom of 6 the facility to a minimum of 0.6 m above final grade with a backhoe working at o: "arms length" to minimize disturbance and compaction of the infiltration surface. en w. 0 Additionally, any required pretreatment facilities should be fully constructed prior co u_ to any release of sediment -laden water to the facility. Pretreatment and shallow W o excavation are intended to prevent the clogging of soil with fines. �? Advantages i v • Protect downstream riparian properties from sediment deposits. z i • Prevent reduced downstream capacity due to sediment deposition in a stream 1- o` z1-;. channel. w w . Prevents clogging in of downstream facilities. D o • • Remove particles up to medium silt size (0.02 mm). o = ` • Surface water conveyances can be connected to the facility as site development ° w: proceeds. The designer may want to route surface water collected from disturbed z 0. areas of the site through a sediment trap prior to release from the site. u. o ui z. Disadvantages • May become an attractive nuisance. Care must be taken to adhere to all safety z ~ practices. • Maintenance and sediment removal is essential for adequate performance. • Serves limited areas. • Does not reduce turbidity resulting from fine silts and clays in runoff. Traps are more effective when used in conjunction with other measures such as seeding and mulching. Design Criteria • Temperature moderation is especially important when a sediment trap drains to salmonid- bearing streams. • Construct prior to any upslope'clearing and grading. • Locate in a low area where the trap will intercept all or most of the runoff from the disturbed area before it enters a waterway, considering safety in case structure fails. • Locate the trap so that it is readily accessible for maintenance. Chapter 1 Erosion Control Page 47 • Provide for diversion dikes and ditches, as needed, to collect and divert water toward the trap. • Design the trap with a level bottom, 1:3 or flatter side slopes and a L:W ratio of 3. Because sediment traps are temporary, the sizing is Tess important to proper functioning than is constant maintenance. 1. Calculate the Storage Volume (V), using 252 cubic meters of storage per hectare of drainage area. Divide the storage evenly between dry and wet storage. For limited space situations, the designer may use a minimum calculation of 126 cubic meters per hectare of drainage. 2. Calculate the trap dimensions using the following: V = [3W + [4WZD + [4/3Z Where: V = Storage Volume W = Width of Trap D = Depth of Trap (Maximum dry storage depth of 1.5 meters) Z = Side slope (1:Z; vertical to horizontal) 3. Calculate the trap length using: L = 3W 4. Approximate the volume in a natural storage area using the following. Surface area and maximum depth depend on site conditions. Volume = (0.4) (surface area) (maximum depth). • Provide a rock weir (spillway) or perforated riser pipe as outlet to the trap. The crest of the weir should be 0.3 meters below the top of the embankment. The weir can be constructed of two layers of different size rock or one depth of 150 mm and smaller riprap. Size the rock for stability during expected flows. • Figure 17 is a riser pipe outlet typical detail developed by FHWA. A typical detail for the riser pipe should show the following: * Pipe perforations which are 13 mm wide by 150 mm long slits or 25 mm diameter holes spaced 150 mm vertically and horizontally above the wet storage elevation. * The riser pipe should be wrapped with 6.4 to 13.0 mm wire hardware cloth and covered with geotextile which is overlapped, folded and fastened at the seam. The geotextile should extend 150 mm above and below the highest and lowest slits and should be secured top and bottom with straps or connecting bands.

If the trap is formed by embankment, the designer should note that dam safety regulation may apply to heights exceeding 1.5 meters. The embankment should be stabilized using a cover method such as seeding, mulching or erosion control matting. • Require installation of a staff gauge to aid in determining sediment depth.

Water temperature in the trap may be too high for direct release. Always moderate the water temperature before it drains into a lake, stream, wetland or waterway. Whenever possible, release the trap discharge onsite onto a relatively level, densely - grassed area at least 20 meters from a water way or wetland. • Evaluate the release areas on a site -b }•site basis in order to determine appropriate locations for and methods of releasing runoff. Do not use vegetated wetlands for this purpose. Refer to FHWA Hydraulic Design of Energy Dissipators for Culverts and Channels. Maintenance • Constant maintenance is essential for proper functioning. • Remove sediment from the trap when it reaches 0.3 m in depth. • Repair any damage to the trap, the embankments or the slopes.

LL. 6 . z ; 0 11.1 0 z Temporary Sediment Basin A sediment basin has one or more inflow points and baffles to spread the flow, wet storage and dry storage, a securely anchored riser pipe, a dewatering device and an emergency overflow spillway. The sediment basin serves drainage areas less than 4 hectares and has a design life of approximately 1 -year. Basins are large facilities which treat runoff from large drainage areas. Because of this, basins have limited application to highway construction projects. The applications, advantages and disadvantages of basins are included here for the designer's edification. For specific design information please refer to Best Management Practices for Erosion and Sediment Control, Report No. FHWA- FLP -94 -005 written by the U.S. Department of Transportation. • Do not drain basins directly into a stream, lake, wetland or other waterway. Water temperature in the basin may be too high for direct release. Always moderate the water temperature before it drains into a lake, stream or waterway. Whenever possible, release the trap discharge onsite onto a relatively level, densely - grassed area at least 20 meters from a water way or wetland. • Applications • Drainage areas from 2 to 4 hectares. • Sites in proximity to salmonid streams, wetlands, or phosphorus- sensitive waterbodies. • Sites where major clearing and.grading is likely to occur during the wet season. • Sites with downstream erosion or sedimentation problems. • Downslope of disturbed areas. Install prior to any upslope clearing and grading. • Combining with Permanent Drainage Facilities 0 If a project includes a permanent storm water retention /detention pond, the rough - graded or final - graded facility could function as a basin during construction. Design features of the permanent structure, such as surface area, retention time and outlet control, should meet the design requirements of the temporary facility. Completion of the permanent facility should occur only when all upstream control structures are in place and stabilization of contributing drainage areas is complete. 0 If a project includes an infiltration facility, the roughly excavated facility could be used as a basin, providing the facility provides the surface area and retention time required by the basin. Excavate the sides and bottom of the facility to a minimum of 0.6 m above final grade with a backhoe working at "arms length" to minimize disturbance and compaction of the infiltration surface. 0 Additionally, any required pretreatment facilities should be fully constructed prior to any release of sediment -laden water to the facility. Pretreatment and shallow excavation are intended to prevent the clogging of soil with fines. 111 "."Pl" 0 " 9 nnno... - �maaw i " .7�'k�'h4'..'sS'Tr11�fir'�'N� 1!", . F�?"' . «. ^". y '.:3:.

Advantages • Protect downstream riparian properties from sediment deposits. • Prevent reduced downstream capacity due to sediment deposition in a stream channel. • Prevents clogging of downstream facilities. • Remove particles up to medium silt size (0.02 mm). • Surface water conveyances can be connected to the facility as site development proceeds. The designer may want to route surface water collected from disturbed areas of the site through a sediment basin prior to release from the site. Disadvantages . • May become an attractive nuisance. Care must be taken to adhere to all safety practices. • Failure of a basin which is not properly located could result in loss of life, damage to homes or buildings or interruption of services such as transportation or power. • Maintenance and sediment removal is essential for adequate performance. • Does not reduce turbidity resulting from fine silts and clays in runoff. Basins are more effective when used in conjunction with other measures such as seeding and mulching.

I am providing a November 28, 2000 updated Certificate of Water Availability from Water District 125 that shows 2900 gallons per minute (gpm) is available for the single family residences to be built by Keystar, Inc. along South 126th Street and 40th Ave. South, Tukwila. Keystar, Inc. recently replaced the old 4" water line along South 126th Street and installed an 8" water line. Two new fire hydrants were also installed; one at the intersection of S.126th Street/40th Ave. South and the other at the intersection of South 126th Street/41st Ave. South. The updated Water Availability Certificate reflects these improvements. Residential permit conditions included a provision that proof of fire flow be provided the Fire Marshal prior to combustibles( i.e. wood for framing) be brought on site for building construction. We understand that Russ Austin, Water District 125, and you discussed that this updated Water Availability Certificate would meet your requirement that tire flow was available. Keystar, Inc. is scheduling wood delivery to the site to commence house framing. We believe with this transmittal of Certificate of Water Availability, Keystar, Inc. has met the Building Permit Condition and the Fire Marshal requirement. Please call Robert Parnell at 425/643 -3560 or Fax 425/641 -5095 to confirm receipt and that the fire flow data transmitted meets permit conditions to allow combustibles to be brought onto sites.

Jill Mosqueda, PE Development Engineer Tukwila Public Works Department 6300 South Center Boulevard, Suite 100 Tukwila, WA 98188 Subject: Keystar Development and River Hills Single Family Residences Dear Ms. Mosqueda: Thank you for your letter of May 21, 2000 on the Keystar Developments. We have shown on the Utility Plan the proposed 8" sanitary sewer line along 126 and the new 8" water line also along 126 The water line would be a looped 8" line system and extend south along 4oth as well as north from the east end of 126 per WD 125 requirements. We have initiated water developer extension with WD 125 and sewer extension with ValVue Sewer District to provide water and sewer to the projects. An 8" DIP water line will replace the existing 4" line and would be a looped system along 40 and 126 and tie into WD 125 system per their requirements. We expect to submit design this month and receive extension design approval within 60 days. Construction should follow by. early September with completion by the late September. • The 8 "sanitary sewer extension would follow approximately the same schedule with the ValVue Sewer District. Upon water and sewer developer extension completion, we would provide water and sewer availability. We understand that for Tots 5 -10, you require 20 foot of paved surface section of 5" Class B asphalt underlain with 3" compacted top course. We understand the individual lot driveways are acceptable. 1 4422 187th Place S.E. • Issaquah, WA 98027 • 425/643 -3560 • FAX 425/641 -5095 c 't eL i R. N.

Mullet, Mayor Department of Public Works James E Morrow, P.E., Director .67At The following is a summary of what we discussed during our meeting with Nora Gierloff on May 18th Adequate water and sewer is not available for the proposed development. Per Jim Morrow, Public Works Director, Public Works will not approve the single family residence (SFR) applications until the water and sewer are installed. Public Works may consider approving the permits once the water and sewer work is underway. Public Works requires a sewer and a water availability letter PER LOT, once the water and sewer are installed. Even though Keystar has not applied for the short plat, several of the requirements for the short plat should be taken into consideration when 6300 Southcenter Boulevard, Suite #100 • Tukwila, Washington 98188 • Phone: 206- 433 -0179 • Fax: 206 - 431 -3665 !K -..ak;: .: May 21, 2000 Page 2 developing Lots A and H. These are: • Five foot wide right of way dedication along 40 Ave. 5. • Fire turn around • Street improvements Public Works will require a legal description, statutory warranty deed and a completed and signed excise tax form for the five -foot wide right of way dedication as part of the short plat process. These documents are not necessary for the SFR applications. Keystar can ignore the short plat preapplication requirement for combined driveways. Brian Shelton, City Engineer, will allow individual driveways for each lot. For Tots 5 -10 and Lots A -H applications, the City requires 20 feet of paved surface on 40 Ave S. and 5. 126 St. Per Brian Shelton, the pavement section shall be 5" of Class B asphalt, underlain with 3" compacted top course, underlain by additional gravel, depth determined by site conditions.

Keystar shall provide a signed and approved set of sewer plans from ValVue BEFORE the City approves the permit applications. 4. The City will investigate the possibility of releasing the building permits for construction of foundations ONLY, so that the building construction can begin before the water service is completed. 5. Once the water service plans are approved, the Applicant shall provide one water availability certificate for each address. The certificate shall show the address and shall show expected flow for that particular lot. The purveyor section of the certificate shall be completed by WD125 WD125 will determine flows per address. If the flow at an address is less than 1000 gpm, the house will need sprinklers, a 1" line, and a 1" water meter to supply the sprinkler system. If an address has a flow of 1000 gpm or more, the house at that address needs only a 4" water meter and 4" line. Please Note: If the building at an address requires sprinklers, the building Department may wish to re- review the plans. L. Jill Mosqueda, P.E.

Meeker St. Suite C Kent, WA 98032-5751 B- twelve Associates, Inc. •: • 4732 40 • oc.com °co o 'lppQ E `� G � P Q EWM This letter report supplements our April 28, 2000 wetland delineation report for the proposed Keystar 6 -lot short plat, and discusses the jurisdictional wetland to the south of the irregulary- shaped, 1.0 -acre property located on the east side of the intersection of 40 Avenue South and South 126 Street, in the City of Tukwila, WA ( "the site "). Per your request, B- twelve has inspected the offsite wet area, located on the adjacent property to the south. A wetland less than one acre in size appears to be present offsite, south of the site's southern property line (see Exhibit A). Because we were unable to obtain access to this property, the soils in the wetland were not examined. Hydrology and vegetation were therefore the only indicators used in determining the approximate location of the wetland edge. Vegetation present in the wetland includes black hawthorn (Crataegus douglasii), nightshade (Solanum dulcamara), buttercup (Ranunculus repens), and Himalayan blackberry (Rubus discolor). Several large black cottonwoods (Populus balsamifera) are rooted just outside of the wetland, on the western side. No trees taller than 20' are located in the wetland, although several small areas may have overhanging trees; therefore, we believe that only emergent and scrub -shrub wetland classes occur in the wetland. Hydrologic indicators present during the site visits included standing water (inundation), watermarks on the ground and vegetation, and matted leaves. The hydrologic inputs to the wetland appear to be primarily from the eastern upland areas. The water appears to drain to the southwest, into the roadside ditches on the east side of 40` Avenue South and the north side of South 128 Street. (v) 253 - 859 -0515 �+ 1 4 1. IVVIWrls,!ri!V s. MIOtm4rnmwo a-a+vwmcrme M a4K VI Mittrv+MA�!l�rvat Z ik_ wy According to the City of Tukwila Sensitive Area Code (Chapter 18.45), the offsite wetland would be categorized as a Type 3 wetland, due to size and number of wetland classes. Typically, wetlands of this type require a 25' buffer, as well as a 10' BSBL in residential areas. That portion of the wetland buffer that is onsite will be put into a buffer easement; therefore, the buffer square- footage can be included as part of the total lot area. Keystar proposes to divide the property that is located south of S. 126 Street (formerly referred to as Parcels A and H) into Lots 1 -6 (see Exhibit A). One single - family residence will be placed on each of these lots. These dwellings will remain outside of the wetland buffer, as well as the 10' BSBL. The offsite wetland edge comes within 15' of the southern property line; therefore, the onsite wetland buffer has a maximum width of 10'. Based on our April 28 report and this supplemental letter report, the Class 3 wetland buffers are located on portions of Lots 3 and 4 (see Exhibit A). Lots 1, 2, 5, and 6 would not have wetland buffer easements. Keystar may propose the placement of a sewer utility (storm or sanitary) on the south side of their site. The sewer will be oriented in an east -west direction, and in some areas, will be within the offsite wetland's buffer. According to the Tukwila Municipal Code, Section 18.45.080 B, construction of new essential utilities may be permitted "only after administrative review and approval by the Director." The locations of the residences, accesses, and infiltration area are such that no other location is feasible for the location of the proposed sewer line. Mitigation will be provided for any disturbances caused in the wetland buffer. In conclusion, B- twelve believes that the proposed activity will cause no loss of valuable wetland or wetland buffer on the site.

Specifically, the site is located in a portion of the SE % of the SW % of Section 10, Township 23 North, Range 4 East of the W.M., in Tukwila, WA. METHODOLOGY 1103 W. Meeker St. Suite C Kent, WA 98032 -5751 B- twelve Associates, Inc. (v) 253-859-0515 (f) 253 - 852 -4732 (e) info @bl2assoc.com cASCS 00' o rrq ..1 1.00 S�Q Ed Sewall and Darcey Miller of B- twelve Associates inspected the property for jurisdictional wetlands and streams on March 29, 2000. A combination of field indicators, including vegetation, soils, and hydrology were used to determine the approximate location of wetland edges. The wetland on site was identified using methodology described in the Washington State Wetlands Identification Manual (WADOE, March 1997). This is the methodology currently recognized by the City of Tukwila and the State of Washington for wetland delineations. The wetland area identified would also be considered a wetland using the methodology described in the Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory, 1987), as required by the U.S. Army Corps of Engineers. The Washington State Wetlands Identification Manual and the Corps of Engineers Wetlands Delineation Manual require the use of the three - parameter approach in identifying and delineating wetlands. A wetland should support a predominance of hydrophytic vegetation, have hydric soils and display wetland hydrology. To be considered hydrophytic vegetation, over 50% of the dominant species in an area must have an indicator status of facultative (FAC), facultative wetland (FACW), or obligate wetland (OBL), according to the National List of Plant Species That Occur in Wetlands: Northwest (Region 9) (Reed, 1988). A hydric soil is "a soil that is saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper part". Anaerobic conditions are indicated in the field by soils with low chromas (2 or less), as determined by using the Munsell Soil Color Charts; iron oxide mottles; hydrogen sulfide odor and other indicators. Generally, wetland hydrology is defined by inundation or saturation to the surface for a consecutive period of 12.5% or greater of the growing season. Areas that contain indicators of wetland hydrology between 5% -12.5% of the growing season may or may not be wetlands depending upon other indicators. Field indicators include visual observation of soil inundation, saturation, oxidized rhizospheres, water marks on trees or other fixed objects, drift lines, etc. Under normal circumstances, indicators of all three parameters will be present in wetland areas. OBSERVATIONS Existing Site Documentation Prior to visiting the site, a review of several natural resource inventory maps was conducted. Resources reviewed include the King County Soil Survey (Snyder et al. 1973), the National Wetlands Inventory Map, and the King County Sensitive Areas Folios. The King County Soil Survey does not have any soil data for the area, because the land was developed prior to the time the surveys were completed. The National Wetlands Inventory Map shows no wetlands or streams located on or within 200 feet of the property. According to the King County Sensitive Areas Folios, there are no inventoried wetlands or streams located on or within 200 feet of the site. Field Observations- Uplands Re: Wetland Delineation Report Keystar/Tukwila Site —Job # A0 -133 B- twelve Associates April 28, 2000 Page 2 of 5 The uplands on the site are disturbed areas, vegetated with big leaf maple (Ater macrophyllum), one cottonwood (Populus balsamifera), red alder (Alnus rubra), Himalayan blackberry (Rubus discolor), and orchard grass (Dactylis glomerata). Soils in the uplands are 1OYR 3/3 and 10YR 3/1 dry gravelly loam/fill. Although the west side of proposed Lots 1 and 2 had some water visible at the time of our site visit on, the soils are not hydric; nor does the vegetation meet wetland criteria. Wetland A (described below) is the only area on site that meets wetland criteria. ti , . �it: iskCi?' ukSh�Jf !ck'.siiLx�(�A;�kjl'' 5 � `V�!ili . 1 Field Observations- Wetlands REGULATIONS PROPOSED PROJECT Re: Wetland Delineation Report Keystar/Tukwila Site —Job # A0 -133 B- twelve Associates April 28, 2000 Page 3 of 5 Wetland A is an isolated wetland, 584 square feet in size, located on the boundary between proposed Lots 4 and 5 of the site (see Exhibit B). B- twelve marked the edge of the wetland with pink "Wetland Delineation" flagging labeled Al -A6. Data points were marked with orange and black flagging labeled DP #1 and DP #2. This wetland and is located in a h ighly disturbed area. A large dead cottonwood is lying on the west edge of the wetland. A small amount of litter was observed within the area of - - the wetland. Wetland A has only an emergent wetland class. Vegetation in the wetland is sparse, and includes primarily blackberry (Rubus discolor) and reed canary grass (Phalaris arundinaceae). Soil pits excavated within the wetland revealed moist gravelly loam/fill soil with a matrix chroma of 10YR 3/1, according to the Munsell Soil Color Chart (see attached Data Forms). The hydrologic inputs to the wetland appear to be precipitation as well as runoff from surrounding uplands. Standing water is present in the wetland, and in some places an oily sheen and/or algae was observed on the surface. According to the City of Tukwila Sensitive Area Code (Chapter 18.45), Wetland A would be categorized as a Type 3 wetland, due to size and number of wetland classes. Typically, wetlands of this type require a 25' buffer, as well as a 10' BSBL in residential areas. Because Wetland A is an isolated wetland less than 1,000 square feet in size, and because the wetland's main function is the storage of a limited amount of surface water, we believe that Wetland A would not be regulated in the City of Tukwila (Section 18.45.115A). Although we are not proposing wetland mitigation for the filling of this wetland, the effects of filling the wetland will be mitigated for in the storm water facilities for the short plat. The property owner proposes to divide the section of the property that is located south of S. 126 Street (formerly referred to as Parcels A and H) into Lots 1 -6 (see Exhibit B). One single - family residence will be placed on each of these lots. B- twelve believes that the proposed activity will cause no loss of valuable wetland or wetland buffer on the site.

SERVICES CONSTRUCTION MANAGEMENT ; 4 / 1 5 �Eclu or L' sFY (1" %, P�a cEtAl Permits South 126 Street/40 Ave. South 1000 GPM Thank you for meeting with Larry Mueller, Keystar President, and myself to discuss Tukwila Fire Department concerns relating to fire flow for the Keystar residential permits on existing lots north and south of South 126 Street. Fire flow requirements for the existing lots are met by a temporary fire hydrant to be installed off the existing 6" diameter water main located at the intersection of South 126 Street and 40 Ave. South that provides 1440 gallons per minute (GPM) per the attached Certificate of Water Availability from WD 125. We understand that with fire flow exceeding 1000 GPM, the Tukwila Fire Department would sign off on the Keystar single family residential permits that are currently being processed. For water service to the proposed six lot short plat south of South 126 Street, Keystar has entered into a Developer extension agreement with WD 125 ( PACE engineers is preparing the water improvement plans) to provide an 8' DIP line from the existing WD 125 10" DIP main within Marginal Way and extend easterly along South 126 Street to 41 Ave. South. Fire flow from the new 8" main line would exceed 2000 GPM. The temporary fire hydrant on the existing 6" main line would be removed and connected to the new 8" main during the new 8" DIP construction. The emergency vehicle turnaround at the east end of South126 Street at 41 Ave. South for the proposed 6 lot short plat would follow the hammer head template shown in handout H -14 and be constructed during the short plat construction.

SUBJECT: Keystar Building Permits DATE: 6/9/00 RE: Building Permits; D2000 -035, D2000 -036, D2000 -037, D2000 -038, D2000 -039, D2000 -077 and D2000 -078 It has been brought to my attention that the Certificates of Water Availability submitted with the referenced Building Permit Applications stipulated that a flow of 880 GPM would be available "after" the upgrade of the existing 4" water main to an 8" line. The Uniform Fire Code, Appendix IIIA, requires a minimum fire flow of 1,000 Gallons Per Minute be available for single family dwellings. The code allows for a 50% reduction in flow requirement when the dwelling has a sprinkler system installed. These requirements are a condition for the issuance of a Building Permit. In this case, the existing Hydrant has a flow of less than 500 gpm, which does not allow construction permits to be issued. The referenced Permits are not to be issued until the improvements identified in the Certificate of Water Availability are completed. The building of numerous residences on small lots close together creates a severe fire hazard during the construction phase. The limited available fire flow would make extinguisment of a fire among unprotected wood frame structures near impossible. This is one of the reasons the code does not allow Building Permits to be issued where there is limited flow.
