HYDROLOGICAL CALCULATIONS USING KCRTS f The following report provides the preliminary drainage report (Level 1 Downstream Analysis) and preliminary TIR required for preliminary plat review and approval, as well as additional discussion of the City of Renton Core and Special Requirement requirements. This preliminary drainage report will be used for development of the full TIR upon final engineering plans and TIR submittal. The following report shall comply with the City of Renton Amendment to the King County Surface Water Design Manual published February 2010_ This project proposes more than 2,000 square feet of new impervious surface and will result in more than 7,000 square feet or more of land disturbing activity. Therefore is subject to the Full Drainage Review criteria and requires discussion of the eight core requirements in Section 1.2 and the six special requirements in Section 1.3. The following Tasks 1 through Task 5 is required to be discussed within the Level 1 Drainage Analysis, TASK 1: DEFINING & MAPPING STUDY AREA: The proposed Nelson 9 lot development is located north of Monterey Avenue NE and NE 121h Street intersection. More specifically the project is located at 2008 121h Street in the City of Renton. (See vicinity map below.) The existing use of the lot is as a 1.62 acre single family residence with mostly grass cover. The proposed plat proposes to develop 9 lots from the exiting single lot and home. All of the areas surrounding the lot is single family residential developments on the upstream sides of the project (north and east sides). The proposed development will allow access from Monterey Avenue from the north and connect with NE 12th Street to the south. Frontage improvements along NE 12th is proposed and includes landscaping, sidewalk and curb/gutter improvements. The stormwater report to be developed forfinal engineering will comply with the 2010 City of Renton Surface Water Design Manual that amends the 2009 King County Surface Water Design Manual.

Upstream areas are primarily from vegetated runoff from the east. Most of the runoff from the east is directed to NE 12°h Street and is conveyed in the NE 12th Street roadside asphalt ditch prior to discharge into the type 1 catch basin with a 12-Inch storm pipe downstream. Runoff generated from Monterey Avenue NE (to the north) is treated and infiltrated into a vault and infiltration tank. This existing treatment vault and infiltration tank spans the entire length of the street. Runoff does not overflow onto the Nelson property. Little to no runoff from the northern property line or from the east along NE 12th drains onsite. Runoff from Aberdeen Avenue NE is not conveyed on to the NE 12th Street system. Aberdeen drains to the south at the intersection of NE 12th and Aberdeen. The downstream analysis is provided in more detail and shall extend approximately more than 1/4 mile downstream in this report. This analysis includes a qualitative evaluation of fish habitat, groundwater levels, groundwater quality, or other environmental features that may significantly be impacted by the proposed project due to it's proximity and project size. A Level 1 analysis is provided for this project site that includes defining and mapping the study area (Task 1), reviewing resources (Task 2), inspecting the study area (Task 3), describing the drainage system and problems (Task 4) and proposing mitigation measures (Task 5). The study area aerial map is provided in the appendix along with the downstream analysis flow direction and basin boundary limits. Data was primarily collected from the City of Renton, USDA (soils), from the geotechnical engineer, from field investigations, and from the King County IMAP database. The following sections (Core Requirement #3 and #8) will be further evaluated and analyzed later during the full drainage review with a TIR submittal. This preliminary analysis has determined that this plat, according to the 2010 City of Renton Surface Water Design Manual Amendment, shall treat for the new PGIS and infiltrate roof runoff due to adequate soils available to infiltrate all runoff into separate Lot BMP infiltration trenches. TASK 2 : RESOURCE REVIEW Resources reviewed include use of Renton existing and potential flooding and erosion data, as builts and discussions with one downstream property owner. The following resource review includes any basin plans (basin reconnaissance summary reports), FEMA maps, sensitive areas folios, USDA sols reports, King County Soils Survey, wetland inventory maps, Renton erosion maps, Renton landslide maps, and any Washington State Department of Ecology's latest Clean Water Act Section 303d list of polluted waters. • Basin Reconnaissance Summary Reports: There exists a downstream Landing development model that was developed by BHC Consultants in 2006 that supported the Landing project and provided basin analyses for the milder gradient areas called the John's Creek system. This project proposes to drain into a pipe that drains to the Johns Creek system and ultimately into Lake Washington. • FEMA Maps: There exists no floodway or floodplain areas near the project site. • Renton Flow Control Application Map: The project site is within the Peak Rate flow Control (with Existing Conditions) applied to the vault retention sizing. The runoff flows into Lake Washington via ultimately Johns' Creek. • Sensitive Areas Folios: o Groundwater Protection Areas: The project area is within the City of Renton Zone 2 aquifer protection area and is within the 10 year capture zone for PW-5A well. o City of Renton Soils Survey Map: The City of Renton soils in the project area is mostly AgD soils. The USDA textural type soils is sandy loam with an SCS classification of type C soils. o Coal Mine Hazard: The project is not within the City of Renton Coal Mine Hazard Area. o Steep Slope Areas: The project site is not within any steep slope protection areas. o Landslide flooding Areas: There exists no landslide flooding areas within 1 mile downstream of the facility. o Seismic Hazard Areas: There exists no seismic hazard areas on the site or within 1 mile downstream on the flowpath. o Erosion Hazard Area: The project is not within an erosion hazard area, but less than 1 mile downstream is an erosion hazard area. o Wetland Areas: There is no SAO wetland in the project area or in the downstream project areas. o Liquidification Area: The site is in a low to moderate liquidification area per the City of Renton. o Drainage Complaints: There have been drainage complaints to the south of the project area according to King County IMAP records. These are closer to the Sunset Drive area and not within the basin or project limits. General Soils Information: The project site is primarily INC or Indianola loamy find sand with up to 4% to 15% slopes according to the USDA— NRCS soils report. InC soils typically have somewhat excessively drained soils with the water table more than 80 inches deep. Typically a sandy layer is present at 30 to 60 inches deep. A soils report was conducted by Dr. CJ Shin a geotechnical engineer from SSEE, Inc. Dr. Shin determined that the infiltration rate is 3.0 inches per hour with a factor of safety of 3, the rate is 1.0 inches per hour for the sandy material. Therefore individual lot BMPs can employ infiltration trenches for roof runoff. The soils report is provided as part of the preliminary plat submittal package. Also the site is located in Renton's Zone 2, so infiltration facilities are allowed within this project area. TASK 3: FIELD INSPECTION A field visit was conducted on October 21, 2011 at 4:30pm in the afternoon. The weather was in the low 50s with rain. Throughout the day there was almost 1 inch of precipitation in the Renton area. Soils onsite were infiltrating runoff into the grasses and runoff from the street was discharging into the catch basins with assistance by the thickened asphalt to collect and direct runoff to the roadside CBs. The downstream runoff pathway was walked and any erosion or other problems were not immediately found within the quarter mile pathway. Portions of the pathway was unable to be safely walked due to the thick vegetation cover (thick blackberries ) and the steep slope. This downstream area was immediately to the west of Lincoln Place NE and NE 121h Street intersection. It is assumed by researched via City records that a conveyance pipe at Lincoln and NE 12th directs runoff down the hill via tightlined pipe. Most of the onsite grassed runoff seems to be infiltrating into the soils and not overflowing onto the street. The eastern property also does not runoff onto the 1.6 acre project lot. The NE 121h Street roadside ditch system with a CB that collects runoff from the road was operating adequately. No sediments were present in the CB. In addition, positive runoff was operating within the CB near the southwestern portion of the NE 121h Street frontage. There appears to be no existing or potential problems on site, downstream of the discharge point the runoff does not appear to be eroding as seen from downhill from the steep slopes and since runoff from NE 12th Street is piped downhill. TASK 4: DRAINAGE SYSTEM DESCRIPTION & PROBLEM DESCRIPTIONS Existing Drainage System Description: The existing drainage from the Nelson site currently sheet flows across grass and discharges towards the southwest portion of the property on a slope between 4% to 8%. There exists no proposed water quality or detention facility within the project boundary. The upstream system is mostly contained and bypasses the existing Nelson lot as described within the the Upstream Analysis section in Task 4 (see below). Proposed Drainage System Description: The proposed drainage system from the site shall not affect any offsite system. Any offsite system's drainage shall maintain it's current flowpath and will not be affected by this development. The on -site system proposes to infiltrate the clean roof runoff into individual lot trench infiltration (or other City approved infiltration BMP) systems. The runoff from each lot's driveway (PGIS) and the new street runoff shall discharge to the tightlined storm pipe system on the proposed Monterey Avenue and be treated within the proposed bioswale located in the southwestern portion of the site's drainage tract. In addition, more trees and shrubs are being proposed to assist in naturally infiltrating into the sandy soils as opposed to the current `grassed' site condition. Overall, the project will treat any new PG IS areas and decrease runoff from the project site using infiltrative methods. Upstream Analysis: The upstream areas of the project site includes three single family homes to the east on NE 12th and homes to the north along Monterey. There are some homes to the east that drains towards Aberdeen and it's drainage system that is conveyed down Aberdeen southward. For purposes' of calculating potential contributing upstream runoff areas, two homes and three eastern grassed yards will be draining towards the project site with the boundary of Aberdeen being the eastern basin boundary. Vegetation to the east is mostly grass and small trees from each lot. The property to the north, on Monterey, intercepts all runoff into a water quality vault located in the middle of the street and an infiltration pipe lying along the east side of Monterey Avenue NE. No utilities are possible to be connected from Monterey due to the vault location. Therefore little to no runoff drains onto the project site from the northern properties. There does not appear to be much or any indications of erosion or heavy runoff coming from offsite to onsite and was confirmed from talking to the owner of 2008 NE 12th Street. The southern border drains to the south via Monterey or Aberdeen and does not affect the project site. The eastern border is confined by Aberdeen, which drains towards the south. Downstream Analysis: A downstream walk was conducted from the project site, towards the natural drainage discharge point westward towards NE 121h and Lincoln. At NE 121h and Lincoln, the runoff is tightlined conveyed downhill (westward), under 1-405, and ultimately is conveyed to the John's Creek stream system via a series of ponds and large culverts. The ultimate downstream point of discharge is into Lake Washington via John's Creek system just north of the new Landing development. A % mile detailed downstream analysis is provided in the following page. This analysis qualitatively provides condition assessments downstream as well as structure details. 3.

The existing drainage system from the site currently either infiltrates into the ground or is carried downstream via the small roadside ditch/conveyance system westwards along NE 12`h Street. Runoff from the site is not significant or will cause additional problems within the downstream discharge point. it is recommended to either use infiltration or detain runoff in a holding vault/pond prior to discharging downstream. Existing Conditions: The existing site conditions for the project site boundary is presently grassed with well taken care of lawn. Most of the site (approximately 85% or more) is grassed. The perimeter of the site is vegetated with an arborvitae type bush. The project site slopes are approximately 4 to 5% without any drastic grade breaks present. The frontage roadside ditch is small and appears to convey some upstream areas with mostly residential and street runoff, but not too much upstream area is present. The type 1 CB located on NE 121h Street and to the southwest portion of the site collects this upstream roadside ditch runoff. The southern half street of NE 121h Street flows south on Monterey Avenue. Proposed Conditions: The project site proposes to develop 9 single family residences (with one of the residences being an existing residence). The project proposes to improve the frontage with curb, gutter, sidewalk and a landscaping strip along NE 121h Street. A new access roadway will be connected from the north (on Monterey Avenue) and will connect to the south along Monterey Avenue. It is anticipated that runoff will be intercepted from the upstream areas of NE 12t4 Street and bypass the onsite system treatment via the proposed 12-inch cpep frontage conveyance system. The project proposes to utilize infiltration trenches for each individual roof runoff and build a bio-swale in the drainage tract along the southwestern portion of the site. The proposed drainage system will try to mimic the existing peak rate runoff (with existing conditions applied) by infiltrating clean roof runoff into the ground and proposing a bioswale to treat any new PGIS. TASK 5: MITIGATION OF EXISTING OR POTENTIAL PROBLEMS The proposed development will have little or no long term impact to the basin or downstream system. The use of a combined water quality and detention system will minimize impacts. Potential temporary problems may occur if the site is left opened up during heavy storm events so erosion and sediment control BMPs must be used during construction if continuous rainfall is expected. A temporary erosion and sedimentation control plan will be created during the final engineering design phase to minimize transport of sediment laden runoff to the downstream system. During construction the use of stabilized entrances, CB inserts to protect downstream inlets and slope/soils erosion BMPs (silt fence, seeding, straw waddles, plastic covering on stockpiles, etc.) will be utilized to reduce impacts to the storm system.

BASIN DELINEATION MAPPING APPENDIX PRELIMINARY CORE AND SPECIAL REQUIREMENTS ANALYSIS SECTION TO BE USED DURING FINAL ENGINEERING DESIGN: Core Requirement #1: Discharge at the Natural Location This project proposes to discharge to the existing discharge location to the southwest. The existing runoff drains south to southwest and along the roadside ditch prior to entering the downstream catch basin on NE 12"'. All proposed runoff shall be the .same as the existing runoff pathways. No adverse impacts are anticipated from this development since no diversion of flows is being proposed and flow increases from the lot is expected to be minimal (less than 0.1 cfs increase for the 100 year peak flowrate using Renton's Peak Flow Control Standard for this project area). Core Requirement #2: Offsite Analysis An offsite analysis is provided in this report that contains the offsite, upstream and downstream analyses (See Task 1 page 5 and Task #4 page 9). This report provides a Level 1 downstream analysis as required by the Renton Storm -water Manual Section 1.2.2.1 and is contained within Task 1 through Task 5. Core Requirement #3: Flow Control The project site is proposing over 2,000 square feet of new or replaced impervious surface and is subject to the area specific flow control facility requirement. The project area is within the Peak Rate Flow Control Standard that mimics existing site conditions as directed by the City of Renton Flow Control Application Map contained in the 2009 Renton Surface Water Design Manual Amendment Reference 11 Maps. Using KCRTS continuous modeling software, this project was mimic'd to match the existing site conditions in order to extract the 2, 10, 25 and 100 year return events from the proposed development. The matching peak rates for the proposed development would be to the 2, 10 and 100 year return events. Per the Peak Rate Flow Control Standard with matching existing conditions per Renton Surface Water Design Manual Section 1.2, the project proposes to also utilize full infiltration trenches for each lot's roof runoff. Infiltration is possible according to the soils report provided with this plat by SSEE, Inc. for the sandy soils. The modeling of each roof area will be credited towards the developed site conditions since the roofs will propose full infiltration by using the depressed infiltration areas in the front or back yards with proper setbacks applied to any buildings. Preliminary soils information from a soils engineer specifies that sandy material has a 3.0 in/hr infiltration rate after applying all safety factors on the infiltration capacity of the site soils of 3.0, the rate used for modeling should be 1.0 in/hour. Final design of each individual trench BMP shall follow the 2009 King County Stormwater Design Manual Section C.2.2.5. In general, either infiltration trenches or ground surface depressions with full infiltration shall be designed during final engineering with at least 60 cubic feet of storm -water per 1,000 square feet of impervious surface served. For example, if 3,000 square feet of house is proposed as the footprint, then 180 cubic feet of volume will be provided. The following is the existing and proposed landuse conditions and it's areas used in the KCRTS modeling: Existing Londuse Area (existing conditions, ind proposed frontage impr.) = 1.69 acres Existing impervious o Roof area = 2677 sf + 662 sf = 0.077 acres o Driveway area = 10,327 sf = 0.237 acres Existing pervious o Grass area = 1.376 acres Proposed Landuse Area (includes frontage improvements) = 1.69 acres minus 0.501 acres for roof runoff infiltration facilities on each lot. Proposed Impervious = 0.334 acres o Sidewalk = 1260 sf + 2930 sf = 4190 Sq-ft (0.096 Acres) o New Asphalt Road = 5,860 sq-ft (0.135 Acres) o Each Building Lot Infiltrated = 2,400sf x 8 (0.055 acres x 8) + 2677 sf (0.061 acres) = 0.501 Acres o 500 square feet area of PGIS from the driveways ... (500 sq-ft x 9) = 0.103 acres modeled as impervious from PGIS. • Note: Everything but the driveway areas will be infiltrated. Therefore buildings should not be counted within the proposed flow rate calculations. Proposed Pervious o Grass = 0.855 Acres EXISTING CONDITIONS PEAK FLOW RATE RESULTS RETURN PERIOD PEAKS (CFS) 2 0.134 10 0.207 25 0.247 50 0.375 100 0.439 • Note: The existing Site area was modeled as grass, some trees, driveway, and one house. DEVELOPED CONDITIONS PEAK FLOW RESULTS RETURN PERIOD PEAKS (CFS) 2 0.124 10 0.165 25 0.193 50 0.290 100 0.339 • Note: Houses were modeled with 500 square feet from each lot due to impervious area from driveways. Actual roadway and sidewalk areas were planimetered using cadd. Each lot shall, including the existing home, will trench infiltrate for approximately 2,000 square feet of house/garage. 100 year Existing conditions = 0.439 cfs 100 year Post -developed conditions = 0.339 cfs Difference in Existing 100 year to Developed 100 year = -0.1 cfs Since the project discharge area will not generate more than 0.1 cfs of flow increase from the existing site conditions, the project is exempt from flow control with 100% full infiltration of each lot's roof runoff as allowed by the City of Renton Peak Rate Flow Control standard for the project area. (See 2009 Renton Surface Water Design Manual Section 1.2.A.) As a matter of fact the project will decrease the 100 year return flow rate generated from the site by 0.1 cfs when all lots implement individual lot BMPS. This runoff will not impact any critical area, any flooding problem or exacerbate any severe erosion problems downstream. Core Requirement ##4: Conveyance System This project will safely convey runoff from the site using 12-inch cpep pipe which is acceptable storm pipe by the City of Renton. The pipe system will be on Monterey and connect into a bloswale located on Tract A — the proposed drainage tract. From the proposed bio-Swale, a discharge pipe will connect to the existing CB located on NE 121". From there, the system flows westward downhill along NE 121h, under 1-405, to the John's Creek drainage system and ultimately into Lake Washington. The system will refine this section of the Core Requirements upon final engineering design with 'real' invert elevations for the designed catch basin and pipe system. It is anticipated that normal 12-inch storm pipe systems will work well for this site since minimal upstream areas enter or pass through the site. Note that an existing storm -water vault is located in the middle of Monterey Avenue immediately to the north of the project site and that system cannot connect to this system whatsoever due to their use of an infiltration pipe and water quality vault for water quality in the middle of the street. Core Requirement #5: Erosion and Sediment Control The project proposes to practically utilize erosion and sediment control BMPs to the extent that the site can contain erosion and sediments from discharging downstream/offsite. The site is more than 1 acres so will require a Department of Ecology storm -water discharge permit with a SWPPP and monitoring during construction. The SWPPP and monitoring will be developed by a Certified Erosion and Sediment Control Lead/ESC supervisor. The erosion and sediment control plans will be developed during final engineering plans submittal. Some BMPS that will be utilized include use of silt fencing, downstream catch basin inserts/protection, straw mats, straw bales, baker tanks (if needed), sediment trap, construction entrance, wheel washing, debris pile coverings, and water trucks_ ESC BMPS that will be used during final engineering design include clearing limits, cover measures, perimeter protection, traffic stabilization, sediment retention, surface water collection, dewatering control and dust control using water tanks. Core Requirement ##6: Maintenance and Operation Any future BMPS will be designed in accordance with current City of Renton standards and/or KCSWDM criteria. The 0&M of the property will be the responsibility of the property/developer as stipulated within the Renton Storm -water Manual 1.2.6. Maintenance responsibilities will be clearly defined during final engineering design for the Final TIR and will coordinate what facilities and who will be responsible for the built system and for how long. Typically the developer will be responsible for maintaining the system until the City takes over the facility after 2 years of performance. It is understood that the private facility may have inspections by the City and deficiencies must be fixed by whoever is responsible for maintenance. Core Requirement V. Financial Guarantees and Liabilities The project will post a bond during / after final engineering in accordance with RMC 4-6-030J via an assignment of funds or certified check. In addition, the applicant shall maintain liability insurance prior to a permit issuance for construction to the amounts of $1,000,000 for commercial general liability insurance with a $2,000,000 aggregate. Copies of this insurance policy shall be provided to the City during / after final engineering. In addition, the applicant will furnish a Construction Maintenance Bond for any new public improvements to be deeded to the City for 2 years. The bond calculation worksheet will be furnished during final engineering submittal. Core Requirement #8: Water Quality Per the 2009 City of Renton Surface Water Design Manual 1.2.8, the project proposes to add more than 5,000 square feet of new PGIS and is proposing to install a bio-swale located on Drainage Tract A. (2009 Renton Surface Water Design Manual, 1.2.8, page 1-61) The total amount of new pollution generating vehicular surface is 0.238 acres or 10,367.3 square feet and will be treated for basic water quality by utilizing the dry bio-swale design option during final engineering. A more detailed bio-swale design is provided in the Grading plan contained within the Preliminary Plans. There is adequate room in the drainage tract for a bio-swale structure and the swale option does a better job of treating runoff than most other structures. Special Requirement #1: Other Adopted Area Specific Requirements The proposed project's drainage basin is within the Lake Washington WRIA 8 — Cedar Sammamish Watershed that contains Lake Washington also. The City of Renton has adopted the WRIA 8 within it's Ordinance for protection Salmon and other wildlife draining to Lake Washington. Any and all endangered species must comply with the WRIA 8 plan for this basin, which this project is within. The project is located upstream of John's Creek within the Lake Washington Basin. John's Creek, located next to Gene Coulon, takes in almost 950 acres and discharges into Lake Washington. There are a few different sub -basins with one coming from the south via the Landing Project that was recently constructed and upstream via the Kennydale Creek system across 1-405 and down to the Garden system. The pipe coming down from NE 121h from the east to John's Creek is minor compared to the Landing and the Kennydale Creek discharges to Garden Avenue. This basin contains information from a recent City of Renton roadway improvement project called the South Lake Washington Roadway Improvement Project which was built prior to the Landing project starting. Another study that was completed by WSDOT, via Parsons, is the John's Creek outfall storm system report which was created for WSDOT. No other basin reports are known to exist for this project. Special Requirement #2: Flood Hazard Area Delineation There exists no flood hazards within the project area or immediately downstream of this discharge location. Special Requirement #3: Flood Protection Facilities There exists no known flood protection facilities in this area, upstream, or downstream. Special Requirement #4: Source Control This project shall contain any stored materials which may contaminate the land and runoff to infiltrate into the aquifer. No short or longterm gasing trucks, containers, or other flammable or toxic chemicals will be stored on -site without proper containment methodologies. Special Requirement #5: Oil Control Oil control is not necessary for this development since traffic through the intersection of NE 121h and Monterey does not exceed 1,000 ADT or more. Special Requirement #6: Aquifer Protection Area The proposed project is located in Renton's Zone 2 - 10 year capture aquifer protection zone per the City of Renton Aquifer Protection Mapping. Since the project is within the City's Zone 2 APA, per RMC 4-6- 030E, the drainage plan submittals and methods of analysis for drainage into, out and through the property shall have it's final engineering TIR prepared and stamped by a professional civil engineer registered in the state of Washington. The drainage plans will conform to Ordinance 4367 and Ordinance 4851. "Zone 2: The land area situated between the three hundred sixty five (365) day groundwater travel time contour and the boundary of the zone of potential capture for a well or well field owned or operated by the City. If the aquifer supplying water to a well, well field, or spring is naturally protected by overlying geologic strata, the City may choose not to subdivide an APA into two (2) zones. In such a case, the entire APA will be designated as Zone 2." nlsnprl.pks Flow Frequency Analysis Time Series File:nlsnprl.tsf Project LOcation:5ea-Tac ---Annual Peak Flow Rates--- -----Flow Frequency Analysis ------- Flow Rate Rank Time of Peak - - Peaks - - Rank Return Prob (CFS) (CFS) Period 0.157 4 2/09/01 2:00 0.339 1 100.00 0.990 0.110 7 1/05/02 16:00 0.193 2 25.00 0.960 0.193 2 2/27/03 7:00 0.165 3 10.00 0.900 0.099 8 8/26/04 2:00 0.157 4 5.00 0.800 0.124 6 10/28/04 16:00 0.154 5 3.00 0.667 0.165 3 1/18/06 16:00 0.124 6 2.00 0.500 0.154 5 11/24/06 3:00 0.110 7 1.30 0.231 0.339 1 1/09/08 6:00 0.099 8 1.10 0.091 Computed Peaks 0.290 50.00 0.980 Page 1 nlsnexl.out KCRTS Command ------------- CREATE a new Time Series ------------------------ Production of Runoff Time Series Project Location : Sea-Tac Computing series nlsnexl.tsf Regional scale Factor 1.00 Data Type Reduced Creating Hourly Time series File Loading Time Series File:C:\KC_SWDM\KC_DATA\STTG60R.rnf Till Grass 1.38 acres Loadingg Time series File:C:\KC_SWDM\KC_DATA\STE16OR.rnf Impervious 0.31 acres -------------- Total Area 1.69 acres Peak Discharge: 0.439 cps at 6:00 on Jan 9 in Year 8 Storing Time Series File:nlsnexl.tsf Time series computed KCRTS Command ------------- Enter the Analysis TOOLS Module ------------------------------- Analysis Tools command ---------------------- Compute PEAKS and Flow Frequencies ---------------------------------- Loading stage/Discharge curve:nlsnexl.tsf Flow Frequency Analysis -------------------------------------------------------- Time series File.nlsnexl.tsf Project Location.Sea-Tac Frequencies & Peaks saved to File:nlsnex2.out Analysis Tools command ---------------------- RETURN to Previous Menu ----------------------- KCRTS Command ------------- CREATE a new Time Series ------------------------ Production of Runoff Time series Project Location sea-Tac Computing series nlsnprl.tsf Regional Scale Factor 1.00 Data Type Reduced creating Hourly Time series File Loading Time series File:C:\KC_SWDM\Kc_DATA\sTTG60R.rnf Till Grass 0.86 acres Loading Time series File:C:\KC_SWDM\KC_DATA\STE16OR.rnf impervious 0.33 acres -------------- Total Area 1.19 acres Peak Discharge: 0.339 CFs at 6:00 on Jan 9 in Year 8 Storing Time Series File:nlsnprl.tsf Time series Computed KCRTS Command ------------- Enter the Analysis TOOLS Module ------------------------------- Analysis Tools command ---------------------- compute PEAKS and Flow Frequencies ---------------------------------- Loading stage/Discharge curve:nlsnprl.tsf Flow Frequency Analysis -------------------------------------------------------- Time series File:nlsnprl.tsf Project Location:Sea-Tac Frequencies & Peaks saved to File:nlsnprl.pks Analysis Tools command ---------------------- RETURN to Previous Menu ----------------------- KCRTS Command Page 1 nlsnex2.out Flow Frequency Analysis Time series File:nlsnexl.tsf Project Location:sea-Tac ---Annual Peak Flow Rates--- -----Flow Frequency Analysis ------- Flow Rate Rank Time of Peak _ - Peaks - - Rank Return Prob (CFS) (CFS) Period 0.199 4 2/09/01 2:00 0.439 1 100.00 0.990 0.130 7 1/05/02 16:00 0.247 2 25.00 0.960 0.247 2 2/27/03 7:00 0.207 3 10.00 0.900 0.104 8 8/26/04 2:00 0.199 4 5.00 0.800 0.134 6 10/28/04 16:00 0.191 5 3.00 0.667 0.207 3 1/18/06 16:00 0.134 6 2.00 0.500 0.191 5 11/24/06 3:00 0.130 7 1.30 0.231 0.439 1 1/09/08 6:00 0.104 8 1.10 0.091 computed Peaks 0.375 50.00 0.98C Page 1 North side of NF 12"' along frontage, looking westward/downhill At northeastern side of frontage looking towards existing house on lot WiL-il r i ..

They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (hftpi//soils.usda.gov/sqi/) and certain conservation and engineering applications_ For more detailed information, contact your local USDA Service Center (http,//offices.sc.egov.usda.gov/locator/app? agency=nres) or your NRCS State Soil Scientist (http://soils.usda.gov/contact! state —offices! . Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey orwet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Soil Data Mart Web site or the NRCS Web Soil Survey. The Soil Data Mart is the data storage site for the official soil survey information.

They include a description of the soils and miscellaneous areas and their location on the landscape and tables that show soil properties and limitations affecting various uses_ Soil scientists observed the steepness, length, and shape of the slopes; the general pattern of drainage; the kinds of crops and native plants; and the kinds of bedrock. They observed and described many soil profiles. A soil profile is the sequence of natural layers, or horizons, in a soil. The profile extends from the surface down into the unconsolidated material in which the soil formed or from the surface down to bedrock. The unconsolidated material is devoid of roots and other living organisms and has not been changed by other biological activity. Currently, soils are mapped according to the boundaries of major land resource areas (MLRAs). MLRAs are geographically associated land resource units that share common characteristics related to physiography, geology, climate, water resources, soils, biological resources, and land uses (USDA, 2006). Soil survey areas typically consist of parts of one or more MLRA. The soils and miscellaneous areas in a survey area occur in an orderly pattern that is related to the geology, landforms, relief, climate, and natural vegetation of the area. Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform. By observing the soils and miscellaneous areas in the survey area and relating their position to specific segments of the landform, a soil scientist develops a concept, or model, of how they were formed. Thus, during mapping, this model enables the soil scientist to predict with a considerable degree of accuracy the kind of soil or miscellaneous area at a specific location on the landscape. Commonly, individual soils on the landscape merge into one another as their characteristics gradually change. To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils. They can observe only a limited number of soil profiles. Nevertheless, these observations, supplemented by an understanding of the soil -vegetation -landscape relationship, are sufficient to verify predictions of the kinds of soil in an area and to determine the boundaries. Soil scientists recorded the characteristics of the soil profiles that they studied. They noted soil color, texture, size and shape of soil aggregates, kind and amount of rock fragments, distribution of plant roots, reaction, and other features that enable them to identify soils. After describing the soils in the survey area and determining their properties, the soil scientists assigned the soils to taxonomic classes (units). Taxonomic classes are concepts. Each taxonomic class has a set of soil characteristics with precisely defined limits. The classes are used as a basis for comparison to classify soils systematically. Soil taxonomy, the system of taxonomic classification used in the United States, is based mainly on the kind and character of soil properties and the arrangement of horizons within the profile. After the soil scientists classified and named the soils in the survey area, they compared the 5 Custom Soil Resource Report individual soils with similar soils in the same taxonomic class in other areas so that they could confirm data and assemble additional data based on experience and research. The objective of soil mapping is not to delineate pure map unit components; the objective is to separate the landscape into landforms or landform segments that have similar use and management requirements. Each map unit is defined by a unique combination of soil components and/or miscellaneous areas in predictable proportions. Some components may be highly contrasting to the other components of the map unit. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The delineation of such landforms and landform segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, onsite investigation is needed to define and locate the soils and miscellaneous areas. Soil scientists make many field observations in the process of producing a soil map. The frequency of observation is dependent upon several factors, including scale of mapping, intensity of mapping, design of map units, complexity of the landscape, and experience of the soil scientist. Observations are made to test and refine the soil - landscape model and predictions and to verify the classification of the soils at specific locations. Once the soil -landscape model is refined, a significantly smaller number of measurements of individual soil properties are made and recorded. These measurements may include field measurements, such as those for color, depth to bedrock, and texture, and laboratory measurements, such as those for content of sand, silt, clay, salt, and other components. Properties of each soil typically vary from one point to another across the landscape. Observations for map unit components are aggregated to develop ranges of characteristics for the components. The aggregated values are presented. Direct measurements do not exist for every property presented for every map unit component. Values for some properties are estimated from combinations of other properties. While a soil survey is in progress, samples of some of the soils in the area generally are collected for laboratory analyses and for engineering tests. Soil scientists interpret the data from these analyses and tests as well as the field -observed characteristics and the soil properties to determine the expected behavior of the soils under different uses. Interpretations for all of the soils are field tested through observation of the soils in different uses and under different levels of management. Some interpretations are modified to fit local conditions, and some new interpretations are developed to meet local needs. Data are assembled from other sources, such as research information, production records, and field experience of specialists. For example, data on crop yields under defined levels of management are assembled from farm records and from field or plot experiments on the same kinds of soil. Predictions about soil behavior are based not only on soil properties but also on such variables as climate and biological activity. Soil conditions are predictable over long periods of time, but they are not predictable from year to year. For example, soil scientists can predict with a fairly high degree of accuracy that a given soil will have a high water table within certain depths in most years, but they cannot predict that a high water table will always be at a specific level in the soil on a specific date. After soil scientists located and identified the significant natural bodies of soil in the survey area, they drew the boundaries of these bodies on aerial photographs and identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately. N. Soil Map The soil map section includes the soil map for the defined area of interest, a list of soil map units on the map and extent of each map unit, and cartographic symbols displayed on the map. Also presented are various metadata about data used to produce the map, and a description of each soil map unit- 7 Custom Soil Resource Report Soil Map 47' 30' 14" 47' 39 10" 0 Map Scale: 1:532 K printed on A size (85" x 11") sheet.

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils_ Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description_ Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in noway diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements_ The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. 10 Custom Soil Resource Report An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important sail properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into sail phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha -Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the surrey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha - Beta association, 0 to 2 percent slopes, is an example, An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example_ 11 Custom Soil Resource Report King County Area, Washington InC—Indianola loamy fine sand, 4 to 15 percent slopes Map Unit Setting Mean annual precipitation: 30 to 55 inches Mean annual air temperature: 48 degrees F Frost -free period: 190 days Map Unit Composition Indianola and similar soils: 100 percent Description of Indianola Setting Landform: Terraces Parent material Glacial drift Properties and qualities Slope: 4 to 15 percent Depth to restrictive feature: More than 80 inches Drainage class: Somewhat excessively drained Capacity of the most limiting layer to transmit water (Ksat).

The site is located at the current address of 2008 NE 12"' Street in Renton, Washington. A site location reap is shown in Figure 1 and a site and exploration plan is shown in Figure 2, both are included at the end of this report. We understand that the proposed development will involve 9 single-family lots, anew road, a storm water detention vault, and infiltration trenches. For the purpose of this study, we have assumed that the structural load of future houses will be typical of residential homes. r 2.0 SCOPE OF SERVICES The purpose of our geotechnical investigation is to develop geotechnical recommendations regarding site preparation and foundation support. Specifically, our services included: 1. Exploration of soil and groundwater conditions underlying the site by the excavation of 4 test pits. 2. Review of published information about potential coal mine and landslide hazards. ;. Recommendations regarding type of foundation support. 4. Recommendations regarding active and at -rest earth pressures to be used for the design of retaining structures. ' 5. Recommendations regarding passive soil resistance and coefficient of friction for the resistance of lateral loads. 1 6. Recommendations regarding temporary and permanent out slopes. 7. Recommendations regarding support for slab -on -grade. 1 1 116rpt S&EE 1 1 1 1 1 8. Recommendations regarding pavement design. 9. Recommendations regarding type of soil for seismic design. 10. Recommendations regarding site preparation, including removal of unsuitable soils, suitability of onsite soils for use as fill, fill placement techniques, and compaction criteria. 1 1 _ Five copies of a written geotechnical report containing a site plan, test pit logs, a description of subsurface conditions, and our findings and recommendations. 3.0 SITE CONDITIONS 3.1 SURFACE CONDITIONS The property is located in a residential area. NE 126 Street borders the site to the south and single-family residences border the site to the east, north and west. The site surface is relatively flat. Currently, a single- family occupies the site. At the time of this report, the majority of the site surface is covered with grass lawn- 3-2 GEOLOGIC INFORMATION Published geologic information (Generalized Geologic Map of Northwestern King County, Washington .State Department of Natural Resources) indicates that the site area is underlain by Recessional Stratified drift (Qvr). The material is mainly a light -gray sand with gravel. 3.3 COAL MINE, LANDSLIDE AND EROSION HAZARDS Coal mine hazards map prepared by City of Renton, Public Works Department, Technical Services, May 21, 2009 indicates no known mine at the site. Sensitive Areas Map published by King County indicates no landslide or erosion hazards at the site. 1116rpt 2 S&EE 1 3.4 TEST PIT FINDINGS The subsurface conditions underlying the site were explored by the excavation of 4 test pits, TP-I to TP-4. The approximate test pit locations are shown on Figure 2. Details of the field exploration program and the test pit logs are included in Appendix A. Our test pits reveal that the site is covered by a few inches of topsoil and is underlain by sands. The sands are brown and gray in colors and are generally medium dense to dense. Judging from its color. constitution and density, we believe that these materials are native soils identified as the stratified drift in the geologic map. No groundwater was encountered in any test pit. 4.0 CONCLUSIONS AND RECOMMENDATIONS 4.1 GENERAL It is our opinion that the proposed development is feasible from a geotechnical standpoint. We believe that conventional spread footings can be used for foundation support. 4.2 SPREAD FOOTING Spread footings should be founded on native sands that are at least medium dense. Recommendations for footing design and construction are presented below. Allowable Bearing Loads: Footings may be designed using an allowable bearing load of 3,000 psf (pounds per square feet). This value includes a safety factor of at least 3, and can be increased by one-third for wind and seismic loads_ Settlement: Interior column footings designed in accordance with the above recommendations are expected to experience approximately 1/2 inch of total settlement. Continuous wall footings should experience settlement of about 1/4 to 1/2 inch. Differential settlement between adjacent footings is expected to be about 1/4 inch. The settlement will occur rapidly, essentially as the loads are applied. Lateral Resistance: Lateral resistance can be obtained from the passive earth pressure against the footing sides and the friction at the contact of the footing bottom and bearing materials. The former can be obtained using an equivalent fluid density of 250 pounds per cubic foot (pcf), and the latter using a coefficient of friction of 0.5. These values include a safety factor of 1.5. 1116rpt 3 S&EE 1 11 Footing Near Slopes: For any footings near slopes of 15 percent or steeper, the bottom of the footing must be positioned in such a way that the horizontal distance from the outside footing edge to the slope face is at Ileast 10 feet. 1 1 Footing Construction: All footing subgrades should be observed by an engineer from our office. Our engineer will confirm the bearing capacity of the subgrade material and provided recommendation for subgrade preparation, if necessary. If our test pits coincide with the future footing locations, the upper 4 feet of the backfill in the test pits should be removed and then backfilled with structural fill. All exterior footings should be founded at least 18 inches below the adjacent finished grade to provide protection against frost action, and should be at least 18 inches in width to facilitate construction_ 4.3 LATERAL EARTH PRESSURES Lateral earth pressures on retaining walls or permanent subsurface walls, and resistance to lateral loads may be estimated using the following recommended soil parameters: Equivalent Fluid Unit Weight (PCF) Coefficient of Friction Active At -rest Passive Native Soils or 40 50 250 0.5 Structural Fill Note: I-lydrostatic pressures are not included in the above lateral earth pressures. The active case applies to walls that are permitted to rotate or translate away from the retained soil by approximately 0.002H, where H is the height of the wall. This would be appropriate for a cantilever ' retaining wall. The at -rest case applies to unyielding walls, and would be appropriate for walls that are structurally restrained from lateral deflection such as basement walls, utility trenches and pits. 1116rpt 4 S&EE 1 1 11 SURCHARGE INDUCED LATERAL LOADS 1) Additional lateral earth pressures will result from surcharge loads from floor slabs or pavements for parking that are located immediately adjacent to the walls. The surcharge -induced lateral earth pressures are uniform over the depth of the wail. Surcharge -induced lateral pressures for the "active" case may be calculated by multiplying the applied vertical pressure (in psf) by the active earth pressure coefficient (Ka). The value of Ka may be taken as 0.3. The surcharge -induced lateral pressures for the "at -rest" case are similarly calculated using an at -rest earth pressure coefficient (Ko) of 0.5. For surcharge loads that are not adjacent to the wall, the induced lateral earth pressure will depend on the magnitude of the surcharge and the distance From the wall. Such induced lateral load can be estimated using the equations shown on Figure 3. 2) The slope -induced lateral earth pressure can be accounted for by increasing the effective height of the wall by one-half the slope height. For back slope continues beyond a horizontal distance equal to the height of the wall, only the part of slope -rise within this horizontal distance should be considered. 3) The traffic -induced lateral earth pressure can be accounted for by increasing the effective wall height by 2 feet. SEISMIC INDUCED LATERAL LOADS Seismic induced lateral loads should be included for the design of retaining walls with imbalanced lateral loads. The dynamic force can be assumed to act at 0.6 H above the wall base. The magnitude can be calculated as 8H (psf), a uniform load over wall height H. BACKFILL IN FRONT OF RETAINING WALLS Backfill in front of the wall should be structural fill. The material and compaction requirements are presented in Section 4.4 of this report. The density of the structural fill can be assumed to be 130 pounds per cubic feet. BACKFILL BEHIND RETAINING WALLS Backfill behind the wall should be free -draining materials which are typically granular soils containing less 1116rpt 5 S&EE Ilan 5 percent fines (silt and clay particles) and no particles greater than 4 inches in diameter. The backfill material should be placed in b to 8-inch thick horizontal lifts and compacted to at least 95 percent of the maximum density in accordance with ASTM D-1557 test procedures. Care must betaken when compacting 1 backfill adjacent to retaining walls, to avoid creating excessive pressure on the wall. 1 1 1 1 DRAINAGE BEHIND RETAINING WALLS Rigid, perforated, PVC drainpipes should be installed behind retaining walls. Drainpipes should be at least 4 inches in diameter, covered by a layer of uniform size drain gravel of at least 12 inches in thickness, and be connected to a suitable discharge location. An adequate number of cleanouts should be installed along the drain line for future maintenance. 4.4 SITE PREPARATION, STRUCTURAL FILL AND DRAINAGE Site preparation should begin with stripping vegetation and topsoil of the structural areas including the driveway, building and slab. The subgrades should then be thoroughly proof -rolled using heavy construction equipment. Areas which are found to be loose or soft, or which contain organic soils should be over -excavated. An engineer from our office should observe the proof -rolling and evaluate the over - excavation requirements. After stripping, over -excavation and excavation to the design grade, the top 12 inches of the native soils should be re -compacted to at least 92% of their maximum dry density as determined using ASTM D-1557 test procedures (Modified Proctor test). Structural fill can then be placed in the over -excavation and fill areas. The structural fill materials should meet both the material and compaction requirements presented below. Material Requirements: Structural fill should be free of organic and frozen material and should consist of hard durable particles, such as sand, gravel, or quarry -processed stone. The on -site sandy soils are suitable for structural fill. These soils are moisture -sensitive and should be moisture - conditioned to +/- 2% from their optimum moisture contents prior to use. Suitable imported structural fill materials include silty sand, sand, mixture of sand and gravel (pitrun), and crushed rock. The use of quarry spalls and crushed recycled concrete should be evaluated by our engineer. All structural fill material should be approved by our engineer prior to use. 1116rpt 6 S&EE n 1 1 Placement and Compaction Requirements: Structural fill should be placed in loose horizontal lifts not exceeding a thickness of 6 to 12 inches, depending on the material type, compaction equipment, and number of passes made by the equipment. Structural fill should be compacted to at least 95% of the maximum dry density as determined using the ASTM D-1557 test procedures. SITE DRAINAGE The site surface should be graded so that surface water is directed away from the structural areas. Standing water should not be allowed. final site grades should be sloped away from the building unless the area is paved, or yard drains installed to collect surface runoff. 4.5 SITE INFILTRATION It is our opinion that infiltration to the native sands is feasible. Based on our field observation and experience with the material, we recommend an infiltration rate of one inch per hour. We believe that this value includes a safety factor of at least 3. Setback from Structures: Infiltration facilities can cause local mounting of groundwater table. This mounting may result in seepage at ground surface in the neighboring properties or facilities. To mitigate such risk, we recommend that the infiltration facilities be located at least 15 feet from any structures. 4.6 TEMPORARY AND PERMANENT EXCAVATIONS When temporary excavations are required during construction, the contractor should be responsible for the safety of their personnel and equipment. The followings cut angles are provided only as a general I reference: For temporary excavations less than 3 feet in depth, the cut bank may be excavated vertically. For temporary excavations greater than 3 feet in depth, the cut should be sloped no steeper than 1 H: I V (one horizontal to one vertical). Flatter slopes for all temporary cuts may be required if seepage occurs. All permanent slopes should be no steeper than 21-1: 1 V. Water should not be allowed to flow uncontrolled over the top of any slope. Also, all permanent slopes should be seeded with the appropriate species of vegetation to reduce erosion and maintain the slope stability. 1116rpt 7 S&EE 1 ll t4.7 SLAB SUPPORT ' Assuming that the site is prepared per recommendations presented in Section 4.4 of this report, al I slabs can be soil -supported. We envision that the slab subgrade will be disturbed and loosened by construction ' activities at the time of slab construction. We therefore recommend that the slab subgrade be proof -rolled prior to concrete placement. Any wet and loose areas should be over -excavated and backfilled with ' structural fill. In order to promote uniform support and provide a capillary break, we recommend that slabs be underlain by a 6 mil. vapor barrier over a 4-inch thick layer of free draining gravel. 4.8 FLEXIBLE PAVEMENT We recommend that the subgrade for flexible pavement be prepared in accordance with the ' recommendations presented in Section 4.4 SITE PREPARATION. Based on the subsoil conditions, we believe that the prepared subgrade will have a California Bearing Ratio (CBR) of at least 12. We ' therefore recommend the following flexible pavement sections for light and medium traffic conditions: Light traffic (Daily EAL = 5 or less): 2 inches asphaltic concrete over 4 inches base course ' Medium traffic (Daily FAL = 20 to 80): 3 inches asphaltic concrete over 6 inches base course ' The base course should be compacted to at least 95 percent of the maximum dry density as determined by ASTM D-1557 test method. The material should meet WSDOT aggregate specification 9-03.9(3) and ' have the following gradation: ' Sieve Size Percent Passim 1 '/a -inch 100 5/8-inch 50-80 ' 1/4-inch 30-50 US No. 40 3-18 US No. 200 7.5 max. ' % Fracture 75 min. 1 1 i I16rpt 8 S&EE 4.9 SEISMIC CONSIDFRATIONS We recommend that Site Class C as defined in the 20091BC be considered for the building design. The site is underlain by dense soils. As such, the liquefaction potential is negligible. 4.10 ADDITIONAL SERVICES Additional services may be required during the design and construction of the project. We envision that these additional services may include the following: 1. Review of design plans. 2. Provision of construction monitoring services. The tasks of our monitoring service typically include the followings: 2.1 Monitoring of site preparation. 2.2 Monitoring of foundations installation. Our representative will confirm the capacity of the foundation bearing soils, and will assist the contractor in evaluating the over -excavation requirements, if any. 2.3 Monitoring the placement and compaction of structural fill. Our representative will confirm the suitability of the fill materials, perform field density tests, and assist the contractor in Tneeting the compaction requirements. 2A Monitoring the installation of subsurface drains. Our representative will confirm that these drains are installed in accordance with our recommendations. 3. Other geotechnicai issues deemed necessary. 7996rpt g S&EE 5.0 CLOSURE ' The recommendations presented in this report are provided for design purposes and are based on soil conditions disclosed by field observations and subsurface explorations.

The approximated test pit locations are shown on Figure 2 - Site and Exploration Plan which is ' included at the end of this report. The test pits were excavated with a Case 580 backhoe. A representative from S&EE was present throughout the exploration to log the subsurface soil conditions. All Itest pits were backfiiled with the excavated soils. The backfill were placed in 2-foot thick lifts and compacted with the backhoe bucket. Test pit logs are presented in this appendix. A chart showing the ' Unified Soil Classification System is included at the end of this appendix. 1 1 i i 1hrpt S&EE 1 1 1 1 1 1 1 1 1 1 1 Tj A � Q o a �, O O oa CO _p fi 10 0 r/5 Soil Description Test pit completed at a depth of 10 feet.
