See Appendix A-1 for the Vicinity Map. The 2016 portable classroom project is proposing to install two double portable classrooms, ramps, stairs, and landings at Talbot Hill Elementary School, and demolish two existing single classroom portables. See Appendix A-3 for the Existing Conditions Plan and Appendix A-5 for the Site Plan. The footprint area of both portables is 3,584 square feet(SF). However, because the portables are partially being placed over existing asphalt, the new impervious surface area from the portable footprint will total 1,856 SF. The area of the existing impervious surface (which will remain impervious because a portable will be placed on it)will total 1,728 SF. These two areas account for the total portable footprint area (1,856 + 1,728 = 3,584). Tables describing basin areas are provided below. During the portable installation, trenching activities will cause existing impervious areas to be considered replaced, and areas added by new ramps and landings result in a total site target impervious surface of 0.072 acre (3,136 SF). In addition, areas of existing impervious surface will be removed completely, resulting in a total site target pervious surface of 0.028 acre (1,220 SF). The total site target surface is 0.10 acre (4,356 SF). See Appendix A-6 for a table of these areas. See Appendices A-7 and A-8 for the Existing and Developed Basin Maps.

The 2009 King County Surface Water Design Manual(KCSWDM) and City of Renton Amendments to the King County Surface Water Design Manual(February 2010) establish the methodology and design criteria used for the project. The King County Runoff Time Series (KCRTS) software program, developed by the King County of Department of Natural Resources, was used to calculate runoff and design stormwater flow control facilities. The Rational method was used to determine conveyance capacities. 2.0 Conditions and Requirements Summary The project triggers Full Drainage Review. Below is a summary of how the proposed project will meet the Core Requirements (CRs) and Special Requirements (SRs). 2.1 CR 1 - Discharge at the Natural Location The natural discharge location for stormwater from the work area is a detention system consisting of 48-inch CMP pipe and a control structure to the west of the project site. See Appendix A-4 for As-Built Information showing the location of the detention system. Stormwater from the asphalt area to the north of the existing portable classrooms and the athletic fields to the south of the portable classrooms both convey stormwater to the detention system in different routes. Stormwater is conveyed from the athletic field with an underdrain system to the south of the existing portable classrooms, and connects via closed pipe to an existing catch basin at the southwest of the existing athletic field in an 8-inch pipe. Stormwater in the existing catch basin is conveyed north in a 12-inch pipe to the detention system to the west of the project site. Stormwater from the asphalt areas to the north of the athletic fields are conveyed via sheet flow to an existing catch basin in the asphalt located between the two existing portable classrooms. Stormwater is conveyed in 8-inch pipe through a series of catch basins onsite up to a storm drain manhole located just east of the school building. Stormwater is then conveyed in 12-inch pipe around the building to the same detention system to the west of the school building. Stormwater is then conveyed west in an existing 12-inch CMP pipe, connecting to the City of Renton storm system running south along Talbot Road South. The COR maps do not indicate this pipe. An AHBL survey crew went to the site on April 6, 2016, and confirmed that the pipe existed. Stormwater roof runoff from the new portables will be discharged from the roof with downspouts. This runoff area is broken into two conveyance basins (north and south). The north basin consists of the roof surface from the northern half of both portables. The south basin consists of the roof surface from the southern half of both portables, plus the area between the portables. Please see Appendix A-8 for a map indicating the developed conveyance basin locations. Stormwater runoff from the north basin of the proposed portables will flow from the proposed roof drain system to a proposed catch basin overbuilt on an existing storm line onsite,just west of the proposed portables. Stormwater runoff from the south basin of the proposed portables will flow from the proposed roof drain system to an existing catch basin approximately 85 feet west of the proposed portables. Stormwater runoff from the north basin is routed through 12-inch pipe that runs around the existing building to the south and enters a 48-inch detention pipe system located at the west of the project site. Stormwater runoff from the south basin connects to an existing catch basin at the northwest of the athletic fields to the south in an 8-inch PVC pipe. Stormwater is then conveyed to a catch basin at the southwest of the athletic field in an 8-inch PVC pipe, before being conveyed to the same existing 48-inch detention pipe system at the west of the project site. All surface and stormwater runoff from the proposed development will continue to be discharged at the natural location, and thus will not adversely affect downstream properties or drainage systems. Technical Information Report ©� Talbot Hill Elementary School 2016 Portable Improvements 2 2150097.10 2.2 CR 2 -Offsite Analysis AHBL staff performed a Level One Downstream Analysis for the project on April 28, 2015. The analysis included: • Defining and mapping the study area. • Reviewing available information on the study area. • Field inspecting the study area. • Analyzing the existing drainage system, including its existing and predicted problems, if any. Please refer to Section 3.0 for the full offsite analysis. 2.3 CR 3 - Flow Control According to the City of Renton COR maps, this project site lies in the Flow Control Duration Standard Area, requiring matching forested conditions. This project meets Exception 2 because the project proposes no more than 0.1 cfs difference in the sum of developed 100-year peak flows for target surfaces subject to this requirement, and the sum of forested site conditions 100-year peak flows for the same surface areas. See Appendix A-9 for pre-and post-developed peak flow rates. The project site has an existing detention system located to the west of the school building, south of the west parking lot. The detention system consists of two 48-inch CMP pipes and provides flow control for a portion of the existing project site. A drawing showing the detention system can be found in Appendix A-4. 2.4 CR 4 -Conveyance System The two new double portable classrooms will include downspouts that tie into roof drain systems prior to entering proposed and existing catch basins onsite. Based on Section 1.2.4.1 of the KCSWDM, new pipe systems shall be designed with sufficient capacity to convey and contain the 25-year peak flow with a minimum of 6 inches of freeboard between the design water surface and structure grate. In addition, runoff from the 100-year peak storm event cannot create or aggravate a severe flooding problem or severe erosion problem. The new pipe system has sufficient capacity for a 25-year peak flow. Catch basin rims do not overtop in the 100-year peak storm event and there is over a 6-inch freeboard between the design water surface and structure grate during the 25-year peak storm event. No severe flooding problems or severe erosion problems are created or aggravated in the 100-year storm event. See Appendix A-10 for the conveyance basin and calculations. 2.5 CR 5- Erosion and Sediment Control Onsite land disturbance will be very minimal and will consist of clearing the work site (approximately 4,180 SF), small amounts of demolition, and regrading for placement of a catch basin. Erosion and sediment control will be provided with the use of temporary and permanent seeding within the work limits, silt fence or wattles, and inlet sediment protection. A Temporary Erosion and Sedimentation Control Plan is included in the plan set. See Section 8.0 for CSWPPP Analysis and Design. Technical Information Report 13MM3 Talbot Hill Elementary School 2016 Portable Improvements 3 2150097.10 2.6 CR 6 - Maintenance and Operations Maintenance and operation of all drainage facilities will be maintained by the owner. The project proposes new catch basins onsite. See Appendix A-14 for Operations and Maintenance Manual. 2.7 CR 7 - Financial Guarantees and Liability This project will provide financial guarantees and liability per City of Renton requirements. See Appendix A-13 for the City of Renton Bond Quantities Worksheet. 2.8 CR 8 -Water Quality No pollution generating surfaces are proposed as part of this development; therefore, the development meets the Surface Area Exemption. CR 8 will not apply. 2.9 SR 1 -Other Adopted Requirements The project is included in the Black River Drainage Basin. City and County basin requirements will be followed where applicable. 2.10 SR 2 -Flood Hazard Delineation The proposed project is not in or adjacent to the 100-year floodplain. See Appendix A-12 for the FIRM Rate Map. 2.11 SR 3 - Flood Protection Facilities This project does not rely on existing flood protection facilities, nor will it modify or construct new flood protection facilities. 2.12 SR 4 -Source Control The proposed project is an educational facility; therefore, it does not fit the definition of a commercial, industrial, or multi-family site for source control purposes. 2.13 SR 5 -Oil Control The site does not meet high use criteria and is not subject to oil control measures. 2.14 SR 6—Aquifer Protection Area According to the City of Renton COR Map Information, the project is not located within an aquifer protection zone. See Appendix A-11 for the City of Renton COR Map Information for the project site. 3.0 Offsite Analysis There are no upstream tributary areas contributing drainage to the north or south conveyance basin areas indicated on the map in Appendix A-8. Technical Information Report 13MI30 Talbot Hill Elementary School 2016 Portable Improvements 4 2150097.10 3.1 Task 1 —Study Area Definition and Maps Talbot Hill Elementary School proposes to place two new portable buildings on the 11.21-acre site located at 2300 Talbot Road South in the city of Renton. AHBL staff visited the site on April 28, 2015. The project site lies within the Black River Drainage Basin, as delineated by the City of Renton COR Map. There are no wetlands on or in the vicinity of the project site. The existing project site consists of three existing single classroom portables, an asphalt playground, an athletic field with an underdrain system, and an existing building. The project site north and south basins receive no upstream water. The basins are defined in Appendix A-8. In the existing conditions, the natural discharge location for stormwater from the work area is a detention system consisting of 48-inch CMP pipe and a control structure to the west of the project site. See Appendix A-4 for As-Built Information showing the location of the detention system. Stormwater from the asphalt area to the north of the existing portable classrooms and stormwater from the athletic fields to the south of the portable classrooms is conveyed to the detention system in different routes. Stormwater is conveyed from the athletic field with an underdrain system to the south of the existing portable classrooms, and connects via closed pipe to an existing catch basin at the southwest of the existing athletic field in an 8-inch pipe. Stormwater in the existing catch basin is conveyed north in a 12-inch pipe to the detention system to the west of the project site. Stormwater from the asphalt areas to the north of the athletic fields are conveyed via sheet flow to an existing catch basin in the asphalt located between the two existing portable classrooms. Stormwater is conveyed in 8-inch pipe through a series of catch basins onsite up to a storm drain manhole located just east of the school building. Stormwater is then conveyed in 12-inch pipe around the building to the same detention system to the west of the school building. 3.2 Task 2—Resource Review The following resources were reviewed to discover any existing or potential problems in the study area: • Civil Engineering Plans: Renton School District Talbot Hill Elementary School prepared by Meng Associates, June 18, 1997. • FEMA Map: FEMA Flood Insurance Rate Map 53033CO979 F, dated May 16, 1995 (see Appendix A-12), indicates that the project site lies within Zone X—Areas determined to be outside the 500-year floodplain. • The City of Renton COR Map: The project site is not located in any of the following mapped critical areas (see Appendix A-11): o Coal Mine Hazard Areas o Erosion Hazard Areas o Landslide Hazard Areas o Seismic Hazard Areas o Critical Aquifer Recharge Areas 0 100-Year Flood Plain o Wetlands Technical Information Report 101800 Talbot Hill Elementary School 2016 Portable Improvements 5 2150097.10 • Soils Information: Site soils have been classified by the USDA Natural Resources Conservation Service (NRCS) as Alderwood gravelly sandy loam material, 8 to 15 percent slopes (AgC) and Beausite gravelly sandy loam, 6 to 15 percent slopes (BeC) (see Appendix A-2). A Geotechnical Report was completed by Associated Earth Sciences Inc. on March 16, 2015, and can be found in Appendix A-2 of this document. • City of Renton COR Maps: The downstream basins were delineated utilizing City of Renton COR Maps, along with a site visit on April 28, 2015. 3.3 Task 3— Field Inspection On April 28, 2015, AHBL staff performed a Downstream Analysis of the drainage system receiving stormwater runoff from the proposed portable classrooms. 1. Investigate any problems reported or observed during the resource review—No problems were reported or observed during the resource review. 2. Locate all existing/potential constrictions or lack of capacity in the existing drainage system — No constrictions or lack of capacity in the existing drainage system was observed. 3. Identify all existing/potential downstream drainage problems as defined in Section 1.2.2.1 — No existing/potential downstream drainage problems were observed. 4. Identify existing/potential overtopping, scouring, bank sloughing, or sedimentation—No existing/potential overtopping, scouring, bank sloughing, or sedimentation was observed. 5. Identify significant destruction of aquatic habitat or organisms (e.g., severe siltation, back erosion, or incision in a stream)—No significant destruction of aquatic habitat or organisms was observed. 6. Collect qualitative data on features such as land use, impervious surfaces, topography, and soil types—The land use on the project site is a school site, which consists of approximately 40 percent of impervious area and sports fields to the south end. 7. Collect information on pipe sizes, channel characteristics, drainage structures, and relevant critical areas (e.g., wetlands, stream, steep slopes)— No critical areas were observed. See Task 4 below for a description on pipe sizes and drainage structures downstream from the project site. 8. Verify tributary basins delineated in Task 1 —Based on the topography onsite, the basin delineation based on the survey was confirmed. 9. Contact neighboring property owners or residents in the area about past or existing drainage problems, and describe these in the report (optional)—This requirement is not applicable for this project. 10. Note the date and weather conditions at the time of the inspection —The site visit occurred on April 28, 2015. The weather was sunny and 60 degrees. Technical Information Report 1318130 Talbot Hill Elementary School 2016 Portable Improvements 6 2150097.10 3.4 Task 4—Drainage System Description and Problem Descriptions In the existing conditions, the natural discharge location for stormwater from the work area is a detention system consisting of 48-inch CMP pipe and a control structure to the west of the project site. See Appendix A-4 for As-Built Information showing the location of the detention system. Stormwater from the asphalt area to the north of the existing portable classrooms and the athletic fields to the south of the portable classrooms both convey stormwater to the detention system in different routes. Stormwater is conveyed from the athletic field with an underdrain system to the south of the existing portable classrooms and connects via closed pipe to an existing catch basin at the southwest of the existing athletic field in an 8-inch pipe. Stormwater in the existing catch basin is conveyed north in a 12-inch pipe to the detention system to the west of the project site. Stormwater from the asphalt areas to the north of the athletic fields is conveyed via sheet flow to an existing catch basin in the asphalt located between the two existing portable classrooms. Stormwater is conveyed in 8-inch pipe through a series of catch basins onsite up to a storm drain manhole located just east of the school building. Stormwater is then conveyed in 12-inch pipe around the building to the same detention system to the west of the school building. The increase in stormwater flow is less than 0.1 cfs in the 100-year storm event. Therefore, the proposed project will not create downstream capacity issues within the existing system. A new catch basin overbuilt on an existing storm line, an area drain, and a roof drain system are proposed for the two proposed double classroom portables. The project area north and south drainage basins are defined in Appendix A-8. Stormwater will flow from the north basin via roof drain to a proposed catch basin overbuilt on an existing storm line adjacent the proposed west portable. Stormwater is then conveyed 33 feet northwest to a storm drain catch basin onsite, and then conveyed north 30 feet to another catch basin to the east of the school building before reaching a storm manhole 7 feet to the east. Stormwater is then routed around the school building to the west where stormwater enters a detention system. Stormwater will flow from the south basin via roof drain to an existing catch basin at the northwest of the athletic fields to the south of the proposed portables. Stormwater is then conveyed southwest 58 feet to another catch basin at the southwest of the athletic fields. Stormwater is then conveyed north to the same detention system located west of the school building. The increase in stormwater flow is less than 0.1 cfs in the 100-year storm event. Therefore, the proposed project will not create downstream capacity issues within the existing system. Stormwater will flow from the detention system control manhole west in a 12-inch CMP pipe to a manhole located on the eastern edge of the northern travel lane of Talbot Road South. Stormwater is then conveyed south approximately 660 feet in a 12-inch concrete pipe along Talbot Road South in a series of manholes, up to a manhole at the intersection of Talbot Road South and South 26th Street. Stormwater is then conveyed south approximately 550 feet in an 18-inch concrete pipe along Talbot Road South in a series of manholes, up to a manhole at the intersection of Talbot Road South and South 27th Street. Stormwater is then conveyed south approximately 680 feet to a manhole on Talbot Road South before being conveyed west in a culvert to Panther Creek. No signs of flooding, overtopping, or erosion were evident at the time of the inspection. Technical albot ill lemetaryScReport C118133 Talbot Hill Elements School 2016 Portable Improvements 7 2150097.10 4.0 Flow Control and Water Quality Facility Analysis and Design The project proposes an increase of no more than a 0.1-cfs difference in the sum of developed 100-year peak flows for target surfaces subject to this requirement, and the sum of forested site conditions 100-year peak flows for the same surface areas, which exempts the project from flow control requirements, per Exception 2 in Section 1.2.3.1(B)of the 2009 KCSWDM. Target surfaces consist of new impervious, replaced impervious, and disturbed areas converted to lawn. The existing impervious surface beneath the proposed portables is to be protected and not disturbed; therefore, the existing impervious surface beneath the portable is not a replaced impervious surface and is not considered a target surface. The basin was modeled using KCRTS per the following conditions: Pre-developed ac Targeted Post-developed ac Forest 0.100 0 Impervious 0 0.072 Grass 0 0.028 Total 0.100 0.100 100- ear Peak Flow cfs Predevelo ed 0.023 Post-developed 0.122 The increase in the 100-year peak flow rate is 0.099 cfs, which is less than the 0.1-cfs threshold. The target surface land cover can be found in Appendix A-6, and detailed calculations to demonstrate exemption from flow control have been included in Appendix A-9. 5.0 Conveyance System Analysis and Design The project proposes collection of storm drainage from the two proposed double classroom portables by roof drain systems. Stormwater from the north basin of the proposed portables is conveyed to a proposed catch basin overbuilt on an existing storm line just west of the proposed portables. Stormwater is then conveyed to an existing catch basin approximately 33 feet northwest. Stormwater from the south basin of the proposed portables is conveyed to an existing catch basin approximately 85 feet west of the proposed portables. Conveyance capacity calculations are included in Appendix A-10. 6.0 Special Reports and Studies There are no special reports or studies necessary for the proposed project. 7.0 Other Permits No other permits are required as part of this proposed development. 8.0 CSWPPP Analysis and Design The proposed development shall comply with guidelines set forth in City of Renton drainage requirements. The plan will include erosion/sedimentation control features designed to prevent sediment-laden runoff from leaving the site or adversely affecting critical water resources during construction. Technical Information Report 13MID0 Talbot Hill Elementary School 2016 Portable Improvements 8 2150097.10 The following measures are shown on the ESC plans and will be used to control sedimentation/erosion processes: • Clearing Limits—All areas to remain undisturbed during the construction of the project will be delineated prior to any site clearing or grading. • Cover Measures—Cover measures will be implemented to the disturbed areas. • Perimeter Protection—Filter fabric fences for site runoff protection will be provided at the downstream site perimeter. • Traffic Area Stabilization—Traffic Area Stabilization is not applicable for this project. • Sediment Retention — Inlet sediment protection will be utilized as part of this project. • Storm Drain Inlet Protection — Inlet sediment protection will be provided on all new and existing catch basins downstream of construction activities. • Surface Water Collection—Catch basins and conveyance pipes will provide surface water collection. • Dewatering Control— Dewatering Control is not applicable for this project. • Dust Control— Dust control measures including sweeping and water truck will be implemented 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. • Flow Control— Flow Control is not applicable for this project. 9.0 Bond Quantities, Facility Summaries, and Declaration of Covenant See Section 2.7 above for CR 7 - Financial Guarantees and Liability. See Appendix A-13 for the City of Renton Bond Quantities Worksheet. Facility Summaries and Declaration of Covenant are not applicable as part of this project. 10.0 Operations and Maintenance Manual Maintenance and operation of all drainage facilities will be maintained by the owner.

Box 4158 Federal Way, Washington 98062 Attention: Mr. Sam Rosendahl Subject: Document Review Portable Classroom Placements Renton School District Multiple Locations Dear Mr. Rosendahl: This report presents the results of Associated Earth Sciences, Inc.'s (AESI's) review of AESI's past project files and exploration logs at schools currently planned to receive new portable classrooms. This summary of available subsurface exploration information has been prepared for the eight elementary schools identified by Greene Gasaway Architects, PLLC. Where past explorations have been identified, preliminary findings, including our opinion regarding the feasibility of storm water infiltration, are provided. Written authorization to proceed with this study was granted by Greene Gasaway Architects, PLLC. This review was accomplished in general accordance with our original proposal letter dated March 6, 2015. This report has been prepared for the exclusive use of the Renton School District, and its agents, for specific application to this project. Within the limitations of scope, schedule, and budget, our services have been performed in accordance with generally accepted geotechnical engineering and engineering geology practices in effect in this area at the time our report was prepared. No other warranty, express or implied, is made. PROJECT AND SITE DESCRIPTIONS We understand that the Renton School District is proposing the placement (or replacement) of portable classroom buildings at the following elementary schools: Kirkland Office 1911 Fifth Avenue I Kirkland,WA 98033 P 1425.827.7701 F 1425.827.5424 Everett Office 1 2911%Hewitt Avenue,Suite 2 1 Everett,WA 98201 P 1425.259.0522 F 1425.252.3408 Tacoma Office 1 1552 Commerce Street,Suite 102 1 Tacoma,WA 98402 P 1253.722.2992 F 1253.722.2993 www.aesgeo.com A-2 Portable Classroom Placements Renton School District Document Review Proposed placement during 2015 • Maplewood Heights: 130-Jericho Avenue SE, Renton, Washington • Hazelwood: 7100- 116th Avenue SE, Newcastle, Washington • Campbell Hill: 6418 S 124th Street, Seattle, Washington • Sierra Heights: 2501- Union Avenue NE, Renton, Washington Proposed placement possibly during 2016 • Tiffany Park: 1601 Lake Youngs Way SE, Renton, Washington • Talbot Hill: 2300 Talbot Road South, Renton, Washington • Lakeridge: 7400 South 115th Street, Seattle, Washington • Bryn Mawr: 8212 South 118th Street, Seattle, Washington We understand that the portable buildings will be self-contained, and each will consist of a wood-frame building supported on concrete foundation bearing strips. A crawl-space floor design is expected, without a slab-on-grade floor. We understand that infiltration of collected storm water is currently under consideration for the proposed portable buildings. AESI DOCUMENT REVIEW - FINDINGS AESI has completed a review of AESI's past project files and exploration logs of the above-listed sites. The following sections provide a brief overview of the anticipated subsurface conditions at each site, based on the data gathered during our document review. Copies of previous AESI exploration logs and site plans reviewed for this study are attached to this report. Maplewood Heights Elementary School AESI completed subsurface explorations at the Maplewood Heights Elementary School (ES) site in January 2012 and January 2015. In summary, these explorations encountered medium dense to very dense Vashon lodgement till, overlain in places by fill. The Vashon lodgement till is generally considered suitable for foundation support of portable classroom structures. We consider the density and texture of the lodgement till encountered in our past explorations, along with our previous experience with sites exhibiting similar soil conditions, to preclude the use of infiltration for the handling of storm water runoff at the Maplewood Heights ES site, in our opinion. March 16,2015 ASSOCIATED EARTH SCIENCES,INC. JPl/pc—KE150128A2—Projects�20250128�KE�WP Page 2 A-2 Portable Classroom Placements Renton School District Document Review Hazelwood Elementary School AESI completed subsurface explorations at the Hazelwood ES site in June, July, August and November 2003, and February 2004. In summary, these explorations encountered medium dense to very dense Vashon lodgement till, Vashon advance outwash, and Tukwila Formation bedrock, overlain in places by fill. The lodgement till, advance outwash, and bedrock are generally considered suitable for foundation support of portable classroom structures. We consider the density and texture of the lodgement till, and bedrock encountered in our past explorations, along with our previous experience with sites exhibiting similar soil/rock conditions, to preclude the use of infiltration for the handling of storm water runoff. The Vashon advance outwash soils, encountered primarily at the northern and eastern portions of the Hazelwood ES site, may be conducive to storm water infiltration. We recommend a site-specific exploration for the proposed portables to evaluate the feasibility of storm water infiltration at the planned locations of the new structures. Campbell Hill Elementary School AESI completed subsurface explorations at the Campbell Hill ES site in December 2000. In summary, these explorations encountered medium dense to very dense ablation till, lodgement till, and Tukwila Formation bedrock, overlain in places by fill. The ablation till, lodgement till, and bedrock are generally considered suitable for foundation support of portable classroom structures. We consider the variability in density and texture of the ablation till, the density and texture of the lodgement till, and bedrock encountered in our past explorations, along with our previous experience with sites exhibiting similar soil/rock conditions, to preclude the use of infiltration for the handling of storm water runoff at the Campbell Hill ES site, in our opinion. Sierra Heights Elementary School AESI completed subsurface explorations at the Sierra Heights ES site in September 1993. In summary, these explorations encountered very dense Vashon lodgement till, overlain in places by fill. The Vashon lodgement till is generally considered suitable for foundation support of portable classroom structures. We consider the density and texture of the lodgement till encountered in our past explorations, along with our previous experience with sites exhibiting similar soil conditions, to preclude the use of infiltration for the handling of storm water runoff at the Sierra Heights ES site, in our opinion. Tiffany Park Elementary School Our research did not reveal past AESI subsurface explorations at the existing Tiffany Park ES site. AESI completed subsurface explorations at a potential Tiffany Park ES site, located to the southeast of the existing Tiffany Park ES campus, in September 2012. In summary, these March 16, 2015 ASSOCIATED EARTH SCIENCES,INC. JPL/pc—KE150128A2—Projects 120150128�KE�WP Page 3 A-2 Portable Classroom Placements Renton School District Document Review explorations encountered medium dense to very dense Vashon lodgement till. Also, our review of the Geologic Map of King County, Washington, by Derek B. Booth, Kathy A. Troost, and Aaron P. Wisher, 2006, indicates that the existing Tiffany Park ES site is underlain by lodgement till sediments. The Vashon lodgement till is generally considered suitable for foundation support of portable classroom structures. We consider the density and texture of the lodgement till encountered in our past explorations at the nearby site, along with our review of the regional geologic map and our previous experience with sites exhibiting similar soil conditions, to likely preclude the use of infiltration for the handling of storm water runoff at the existing Tiffany Park ES site, in our opinion. We recommend a site-specific exploration for the proposed portables to evaluate the feasibility of storm water infiltration at the planned locations of the new structures. Talbot Hill Elementary School AESI completed subsurface explorations at the Talbot Hill ES site in April 1996. In summary, these explorations encountered very dense lodgement till and Renton Formation bedrock, overlain in places by fill. The lodgement till and bedrock are generally considered suitable for foundation support of portable classroom structures. We consider the density and texture of the lodgement till, and bedrock encountered in our past explorations, along with our previous experience with sites exhibiting similar soil/rock conditions, to preclude the use of infiltration for the handling of storm water runoff at the Talbot Hill ES site, in our opinion. Lakeridge Elementary School AESI completed subsurface explorations at the Lakeridge ES site in April 1991, January 1993 and March 1994, and issued a letter dated April 22, 2014 providing our opinion regarding the feasibility of storm water infiltration, based on previous explorations in the vicinity of the site. In summary, the referenced explorations, both on-site and in the vicinity, encountered very dense Vashon lodgement till, overlain in places by fill. The Vashon lodgement till is generally considered suitable for foundation support of portable classroom structures. As mentioned in our April 22, 2014 letter, we consider the density and texture of the lodgement till encountered in our past explorations, along with our previous experience with sites exhibiting similar soil conditions, to preclude the use of infiltration for the handling of storm water runoff at the Lakeridge ES site, in our opinion. Bryn Mawr Elementary School Our research did not reveal past AESI subsurface explorations at the Bryn Mawr ES site. AESI recently issued a proposal to complete subsurface explorations for support in design of ADA improvement at the existing Bryn Mawr ES campus. We recommend that these explorations be March 16, 2015 ASSOCIATED EARTH SCIENCES,INC. JPL/pc—KE150128A2—Projects�20150128�KE�WP Page 4 A-2 Portable Classroom Placements Renton School District Document Review expanded to include a site-specific exploration for the proposed portables to evaluate the feasibility of storm water infiltration at the planned locations of the new structures. CLOSURE We are pleased to have had the opportunity to prepare this summary of anticipated subsurface conditions at the above-listed sites, based on the data gathered during our document review. We are confident that this report will aid in your design process. As stated above, we recommend that site-specific explorations be completed for selected sites where currently- available information is lacking or suggests variability in subsurface conditions.
