Geotechnical and Environmental Consulting Subject: Report of Geotechnical Services 6 Lot Short Plat on South 126 Street Tukwila, Washington Dear Mr. Parnell: SITE AND PROJECT DESCRIPTION zer g. J -671 March 13, 2000 Zipper Zeman Associates, Inc. (ZZA) has completed a geotechnical evaluation for the above - referenced short plat. This report presents the results of our subsurface exploration and geologic reconnaissance relative to general foundation and construction considerations, as well as the City of Tukwila Sensitive Area designations for the project site. The field evaluation was completed on March 6, 2000. The purpose of the evaluation was to establish general surface and subsurface conditions at the site from which conclusions and recommendations regarding foundation design and construction considerations could be formulated, and to address Sensitive Area designations as defined by the City of Tukwila. The scope of our work consisted of subsurface test pit 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. 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 :!rcttr5.WwaR`7 tr4A 'rpwkneea :: Lynnwood, Washington 98036 240o-43 6 Lot Short Plat on South 1 Lo' Street Tukwila, Washington 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 19231— 36ty Avenue W., Suite B201 Zipper Zeman Associates, Inc. Lynnwood, Washington 98036 J -671 March 13, 2000 • Page 2 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 (425) 771-3304 r,Y.rx :r41p ,,fir9LellR "`7+ ,�fhY..nw<:vs�WML: "" z•. �n:.^.»:. neUYniia: yri..:. e» rr.. r. �rU� r��w: y.;., t..-: rrc; s+:. v2 r�! r, r. a r y v a�::;.

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 16 -J 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 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.

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. 19231— 36ty Avenue W., Suite B201 1,0 ,•'`.u}.T.

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 19231— 36ty Avenue W., Suite B201 1rn.• Ayl ec?Ss "m9:;I 4^p,++r'n�urrxrc " •.s;:; • �••� -�. •i.�n ,� J -671 March 13, 2000 Page 6 Zipper Zeman Associates, Inc.

Under no circumstances should footings be cast atop loose or soft soil, slough, debris, or surfaces with standing water. We recommend that a representative from our firm observe the condition of the footing subgrades prior to pouring footing concrete, or a lean concrete mud mat, in order to verify that the bearing soils are undisturbed and that conditions are consistent with the recommendations contained within this report. We recommend that each new house be protected by a perimeter footing drain. The drain should consist of a minimum 4 -inch diameter perforated pipe embedded in at least a 18- 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 slopes. Roof drains should not be connected to the footing drains 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 dense to very dense native soils, or on compacted structural fill extending down to the medium dense to very dense native soils. Slab -on -grade floors should not be founded on or within loose or disturbed native or fill soil unless it has been evaluated and approved by the geotechnical engineer. We recommend that slab -on -grade floors be underlain by a minimum 4 -inch thickness of coarse sand and gravel to provide uniform support and act as a capillary break. In floor slab areas where moisture sensitive floor coverings are planned, an impermeable membrane (e.g. polyethylene sheet) should be placed directly beneath the floor slab to act as a 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 underslab drainage for the new houses. This issue should be evaluated by our firm once final building configurations and floor grades have been established. Backfilled Walls 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 Zipper Zeman Associates, Inc. 19231 — 36ty Avenue W., Suite B201 Lynnwood, Washington 98036 �eY1�1; �07�tt ±Tl�?"';?tfP�101tt,.YASY4.'�'�.

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.

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.

PARNELL COMPANY CIVIL ENGINEERING WATER RESOURCES ENGINEERING MANAGEMENT ENVIRONMENTAL SERVICES CONSTRUCTION MANAGEMENT Site clearing was completed in March 2000 and subsequently stopped by city of Tukwila. Erosion control was placed in the form of sediment fabric fence along the perimeter and hydroseeding on those areas exposed and not worked. The site was inspected on April 5, 2000 and the parcels cleared areas were stabilized and the fabric fence upright and functioning. No erosion was noted. Clearing limits are the full site areas for each lot and proposed lot when residential building commences due to the configuration, size, and area of the lots. Total area of the 8 lots is about 2 acres. The two parcels to the south of South 126 Street are in the process of being short plat, therefore there are only two legal lots south of South 126 Street and six lots north of south 126ht Street at this time for residential construction permit purposes. Residential building permit applications have been submitted and are being processed by the City of Tukwila, and the applicant is providing supplemental information as requested, including this resubmittal. Residential construction will commence just as soon as the permits are issued by the City of Tukwila. Erosion control is part of the permit conditions and will be placed during construction to prevent sediment from leaving the site. 4422 187th Place S.E. • Issaquah, WA 98027 • 425/643 -3560 • FAX 425/641 -5095 "."" .15" f'{fii2t?4{.'mtv 3 '''!P.wnv "NTV7d W.4^T!ttrFtwrt1hN iN'A'^; `MI!gY+'.t . „ 0, M:"kiiC'!n.'F'rltv."11••: RECEIVED CITY OF TUKWILA SEP - 2000 PERMIT CENTER !t' to tU'.IfNM%t� ?rcb.'!e4:9 z z J U U CO O w= J .

L I O . An 8" DIP water line will replace the existing 4" line and would be a looped 11J cn system along 40 and 126 and tie into WD 125 system per their requirements. o We expect to submit design this month and receive extension design approval z 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 lots 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.

Dear Ms. Holt: PERMIT CENTER We are providing the following information in order to help complete your file on Keystar, Inc. residential permit D2000 -039 which is identified as Lot H. Lot H is also a lot within a proposed 6 lot short plat located south of S. 126th Street in the River Hills area. The proposed 6 lot short plat had a preapplication meeting, however, Lot H Building Permit application is the development requested under permit D2000 -039. Applicant's recent inquires as to permit status for city approval resulted in staff response that your computer tracking system shows that the file needs to reflect the applicant has responded to the city's May 15,2000 letter requests for corrections. We understand that although the information requested was submitted for related actions to the land parcel, a specific response and 4 copies of the information provided must be also submitted for any specific permit. We prepared a response to Correction Letter dated March 8,2000 referencing the March 7,2000 Planning Division wetland comments by my letter to you dated April 19, 2000 that include B -12 Associates, Inc. Wetland Delineation Report dated April 19,2000. The results were that the wetland on site was located at least 80 feet away from the proposed residential site and that the 584 square feet class 3 wetland is not regulated by the city. My records show you logged my response in on April 19, 2000 Subsequently, your May 15,2000 letter referenced the Public Works April 28,2000 comments and the May 10, 2000 Planning letter concerning an offsite wetland to the south of Lot H. Apparently, I need to respond to your May 15 Correction Letter # 2 and formally provide a copy of the completed April 28,2000 wetland report and the June 13, 2000 supplemental through the permit counter. Those two wetland documents are enclosed (4 copies each along with the revision submittal form.) We are also providing 4 copies of the Geotechnical Report for the two parcels ( 6 lot short plat that includes proposed Lot H), copies of the erosion prevention and sediment control plan that includes installation and maintenance timing and construction access and stabilization and the proposed 5 foot wide right of way dedication should the proposed 6 lot short plat be recorded.

Parcel grading, Geotechnical Report and erosion control were included as part of the TIR and Grading Plan dated April 24, 2000. Subsequent requests direct from Public Works or clarification of Public Works requests were coordinated direct with Public Works, and the Fire Marshall as related to fire flow, and we understand that documentation provided has been accepted. Copies of the latest documents are provided for this file. Domestic water, fire flow, and sanitary sewer requirements listed in the Public Works memo dated June 12, 2000 were discussed with management level city staff. Based on those discussions and resulting decisions, permits were issued, with conditions, for the River Hills single family residences on the north side of South 126th Street. We understand that those same conditions are applicable to Lot H. Discussions with the Fire Marshal, as recent as August 31,2000, confirmed that he would allow the Lot H Building Permit with conditions The Revision Submittal form for Correction Letter #2 dated May 15,2000 is attached.

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.

Meeker St. Suite C Kent, WA 98032 -5751 B- twelve Associates, Inc. This letter describes the jurisdictional wetland on 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 "). Specifically, the site is located in a portion of the SE 1/4 of the SW 1 /4 of Section 10, Township 23 North, Range 4 East of the W.M., in Tukwila, WA. 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: (v) 253-859-0515 (f) 253 - 852 -4732 (e) Info @b12assoc.com aq m1r r!:^.c .`f;,' 'v c'em!mt vcSc im it pootv,cr! Ipm..mrmg E vEn twri ni l- Qr Arse rlexttrig.rxiF.H. , mov,�+ wml 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 Re: Wetland Delineation Report Keystar/Tukwila Site —Job # A0 -133 B- twelve Associates April 28, 2000 Page 2 of 5 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 The uplands on the site are disturbed areas, vegetated with big leaf maple (Acer macrophyllum), one cottonwood (Populus balsamifera), red alder (Alnus rubra), Himalayan blackberry (Rubus discolor), and orchard grass (Dactylis glomerata). Soils in the uplands are 10YR 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. z ~w ' ce 00 0 Cl) w J H w tL w o u. w d �w z = 1-- o w ~ w 0 o 0 I-. w ill z . • = OH • z Field Observations - Wetlands 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 highly disturbed _ turbed 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. REGULATIONS 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. PROPOSED PROJECT 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.

Meeker St. Suite C Kent, WA 98032 -5751 B- twelve Associates, Inc. (v) 253-859-0515 (f) 253-852-4732 (e) info @b12assoc.com 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. RECEIVED CITY OF TUKWIIA SEP - 2(100 PERMIT CENTER 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.

Parnell, PE Date: November 29, 2000 Pages: Four (4) Subject: Keystar Single Family Permits: South 126 Street/40 Ave. South Permits:D2000 - 035, 036, 037, 038, 039, 077, 078 Fire Flow of 2900 Gallons Per Minute 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 fire 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. Your assistance and understanding has been greatly appreciated. CC; Larry Mueller /Steve Araki / Keystar, Inc.

Design Criteria • Assess the impacts of allowing water to pond at the inlet and provide an overflow weir or some other type of relief as needed. • Consider the effect placing obstructions at inlets on grade may have on their efficiency. Refer to ODOT's Hydraulic Manual or contact the Hydraulics Unit when placing protection at several inlets on grade along a roadway section. • When possible, include a sediment sump 300 to 600 mm deep with 1:4 side slopes. * Silt Fence Inlet Protection - At non -paved inlets below drainages having less than a 5% slope. Provide a sump. * Gravel . Wire Mesh Inlet Protection - Applicable for inlets in construction traffic reas which receive flows greater than 0.014 m /sec. * Catch Basin Insert Inlet Protection - At inlets below drainages flatter than 5% slope. The filter material should retain sediment 0.6 mm and larger, while allowing the runoff to pass at or near the inlet's design flow rate. Maintenance • Do not use water to remove sediment. • Remove sediment accumulated on or around the protection as needed to maintain intended functions. • Repair or replace materials as needed to ensure proper functioning.

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.

By dissipating energy, outlet protection lowers the potential for downstream erosion. Outlet protection includes riprap -lined basins, concrete aprons, and settling basins. Figure 11 Common outlet protection techniques. Applications • At the outlets of ponds, pipe slope drains, ditches, or other conveyances, and where runoff is conveyed to a natural or man -made drainage feature such as a stream, wetland, lake, or ditch. Advantages • Many techniques are effective and relatively inexpensive and easy to install . • Removes sediment and reduces velocity. Disadvantages • Can be unsightly. • May be difficult to remove sediment without removing and replacing the structure itself. r ill.MPIYAWI Chapter 1 Erosion Control Page 37 Disadvantages • Measures may be unsightly. • Removal may be costly for some types of check dams. • Suitable only for a limited drainage area. • May reduce hydraulic capacity of the channel. • May create turbulence downstream, causing erosion of the channel banks. • Ponded water may kill grass in grass -lined channels Design Criteria • Space check dams according to the following table. 6% 5% 4% 3% 2% Minimum>Rock;Depth: _ '' 5m O.C. 6 8 10 15 450 ;mm 8m O.C. 9 12 15 24 • Construct rock check dams of rock or aggregate sized to stay in place given the expected design flow velocity. Place rock or aggregate by hand or by mechanical means rather than dumping the rock. • Completely cover the ditch or swale width and ensure the center of the dam is 150 mm lower than the upper ends. • Remove check dams from grass -lined ditches and swales once the grass is established. Be sure to remove rock which was carried downstream. • Seed and mulch the area where the check dams were immediately following removal. Maintenance • Periodically inspect check dams for performance and sediment accumulation. • Remove sediment once it reaches one -half the sump depth. :L'•» �` Aia*&24. - =Cl.[ski,giz14i AG15 Chapter 1 Erosion Control Page 36 ce w 6 = J U UO .

The plan shall provide information for temporary erosion prevention and sediment control during all phases of construction and also shall provide permanent stabilization for disturbed areas. During construction, the City may require additional measures as needed to prevent erosion and retain sediment. 1. Principles — The plan shall emphasize erosion prevention rather than sediment control and shall minimize the extent and duration of soil exposure. In addition, the plan shall minimize runoff -off velocities and retain sediment on -site. 2. Plan — At a minimum the ESC plan shall show clearing limits, sensitive area buffers, and shall provide temporary stabilization, sediment retention , and perimeter protection. In addition, some projects will require stabilized traffic areas and surface water controls, which shall be shown on the ESC plan. The plan shall also provide a description of final stabilization methods. 3. Seeding — The plan shall provide the seed mix for the temporary and permanent seeding. 4. 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. 5. 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.

I o 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. Disadvantages • 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.

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 - bearing streams. • Retains existing shade and cover habitat. Disadvantages • Retaining older trees could create a safety hazard. • May constrict area available for construction activities.

Chapter 1 Erosion Control Page 17 Maintenance • Inspect and repair flagging or fencing. • Re -cover and /or seal exposed plant roots. • 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 tile 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. 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.

Mulching and irrigation may be required for 2 areas seeded during the hot summer months. u_ • Seed applied during the winter may take several months to develop a dense = C! . ground cover due to cold temperatures. The application and maintenance of t- _ m ulch is critical for winter seeding. z o : • To prevent seed from being washed away, confirm installation of all required w o w surface water control measures. 2 o U � O N Seedbed Di— • Prepare a firm but not compacted seedbed. Roughen slopes steeper than i 0 1:3. The typical method is track - walking (driving a crawling tractor up and u_ o down the slope) creating cleat imprints parallel to the slope contours. w z U = Seed Mixes o E' • Provide project - specific seed mixes and application rates in the 00280 z 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 :„X Y+7+�dpx!rumor{m l!

Hydroseed 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 Toss and transport due to runoff and provides effective cover for seeding during the dry season.

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 Z 6 0 ~ w 00 0 wI w j . D. a 1- w z � z I- IL w U� 0 -. o w 1- L I o w U= P: 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 • 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.

Good ground o cn contact during installation prevents runoff concentrating under the blanket and u j causing significant erosion. _ o "-- o z Cu • Apply as temporary slope stabilization according to 00280 Supplemental. o � • Organic blankets (excelsior, jute and coir) biodegrade and are useful for applications Z 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. Design Criteria • Synthetic mats are made from non - biodegradable material and will remain in place for years. Use purely synthetic blankets for long -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.

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. Plastic Sheeting 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. 3m MAX.

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. Minimum width: 6 meters. Minimum Aggregate Depth: 200 mm • Install construction entrances before beginning grading.

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.

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. vK`c*ai. 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- by*.ite 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.

The sediment basin serves drainage areas less than 4 hectares and has a design life of approximately 1 -year. z ~ w 6 00 N 0 CO W J w • o • Do not drain basins directly into a stream, lake, wetland or other waterway.

Whenever = w possible, release the trap discharge onsite onto a relatively level, densely - grassed z area at least 20 meters from a water way or wetland. z o w Applications • Drainage areas from 2 to 4 hectares. o D- • Sites in proximity to salmonid streams, wetlands, or phosphorus- sensitive w w waterbodies. x 0 • Sites where major clearing and.grading is likely to occur during the wet season. o • Sites with downstream erosion or sedimentation problems. w Z • Downslope of disturbed areas. Install prior to any upslope clearing and grading. p I 0 z 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. • 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 uarms 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. Chapter 1 Erosion Control Page 51 SOURCE: King County - I 1 1 11 =11 Supported Silt Fence.
