Project No.2150095.10 1.0 Project Overview Maplewood Heights Elementary School is located at 130 Jericho Avenue NE on Parcel No. 0847100090 Renton, Washington. See Appendix A-1 for a Vicinity Map. The project site area is 8.67 acres, with 4.11 acres of existing impervious coverage. The 2015 portable classroom project proposes to install three double portable classrooms, ramps, stairs, and landings at Maplewood Heights Elementary School, and demolish four existing single classroom portables. See Appendix A-3 for the Existing Conditions Map and Appendix A-4 for the Site Plan. This would result in 5,594 square feet (SF) of new impervious surface and 1,043 SF of replaced impervious surface (total of 6,637 SF of new plus replaced impervious surfaces). In addition, 1,610 SF of impervious surface will be converted to pervious lawn. The site will realize a net increase of 3,984 SF of impervious surfaces. See Appendices A-5 and A-6 for Existing and Developed Basin Maps. The 2009 King Counry Surface Water Design Manual(KCSWDM) and Cify of Renton Amendments to the King County Surface Water Design Manual(February 2010)establish the methodology and design criteria used for the project. The Rational Method was used to determine conveyance capacities. 2.0 Conditions and Requirements Summary The project triggers Full Drainage Review because it results in more than 7,000 square feet of land disturbing activity and over 2,000 square feet of new and/or replaced impervious surface. Below is a summary of how the proposed project will meet the Core Requirements (CR). 2.1 CR 1 -Discharge at the Natural Location The natural discharge location of stormwater for the project area is the grass field south of the existing portables. Stormwater flows southwest across the field to SE 2`� Place and is conveyed along the north curb flow line of SE 2"d Placer�., Stormwater then enters a catch basin located southwest of the project site on SE 2nd Place. Stormwater is then co�eyed in an 8-inch pipe to a catch basin at the northeast comer of the intersection of SE 2"d Place and Jericho Avenue SE. Stormwater is then co�veyed through an 18-inch concrete pipe through a series of catch basins west along SE 2nd Place, up to a storm manhole adjacent to the intersection of SE 2"d Place and Hoquiam Avenue. Stormwater is then conveyed to the south in a 48-inch pipe and outfalls to Maplewood Creek. Stormwater roof runoff from the proposed portables will be discharged from the roof with downspouts, and will flow through a series of proposed catch basins and cleanouts prior to discharging to a gravel-filled trench for flow control. A minimum of approximately 80 feet of grass-vegetated flow path segment is provided upon discharge from a gravel-filled trench, and thus exceeds the 25-foot minimum requirement specified per KCSWDM C2.4.4. Roof and site runoff will flow overland and discharge at the natural location, and thus will not adversely affect downstream properties or drainage systems. 2.2 CR 2-Offsite Analysis AHBL staff performed a Level One Downstream Analysis for the project on March 18, 2015. The analysis included: • Defining and mapping the study area. • Reviewing available information on the study area. Tec�hnical Info 9ation Report ry �� . � Ma lewood Hei hts Elementa School Portables 1 p.,.l.,�� ,. �,G�noc ,n • 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 Full dispersion of roof runoff was evaluated. Per Appendix C.2.1.1 of the KCSWDM, a native, vegetated, flow path segment of at least 100 feet in length must be available along the flow path that n.�noff would follow upon discharge from a dispersion device. A native, vegetated flow path of 100 feet is not available onsite. Therefore, full dispersion is not feasible. Full Infiltration of roof runoff was evaluated. Based on the infiltration assessment by Associated Earth Sciences, Inc. (found in Exhibit A-2, pg. 2), the soils are described as medium dense to very dense Vashon lodgement till. The glacial till soils are not recommended for infiltration due to the very dense and fine-grained nature. Therefore, full infiltration is not feasible. Based on Figure C.1.3.A, one or more of the following Best Management Practices (BMPs) must be implemented for target impervious surface not addressed with full dispersion or with full infiltration of roof runoff: 1. Full Infiltration—As described in the geotechnical report, the site soils do not allow for su�cient infiltration; therefore, full infiltration is not feasible. Please see Exhibit A-2. 2. Limited Infiltration —As described in the geotechnical report, the site soils do not allow for sufficient infiltration; therefore, limited infiltration is not feasible. Please see Exhibit A-2. 3. Basic Dispersion — � a. Splash�Blocks —Per KCSWDM C2.4.2, splash blocks require a 50-foot vegetated flow path between the dispersion device and any downstream impervious surFace or drainage feature. The proposed asphalt walks are within 6 feet of the building; therefore, splash blocks are not feasible. b. Rock Pads—Per KCSWDM C2.4.3, rock pads require a 50-foot vegetated flow � path between the dispersion device and any downstream impervious surface or drainage feature. The proposed asphalt walks are within 5 feet of the building; therefore, splash blocks are not feasible. c. Gravel-Filled Trenches—The project proposes three gravel-filled trenches. The gravel-filled trenches are described in the ne�paragraph. Based on a meeting with AHBL and Steve Lee of City of Renton on March 11, 2015, dispersion was determined to be an acceptable flow control measure for this project. d. Sheet Flow—Per KCSWDM C2.4.5, sheet flow is not used for roof downspouts; therefore, sheet flow is not feasible. Technical Information Report O Q O O Maplewood Heights Elementary School Portables 2 . Project No. 2150095.10 Three gravel-filled trenches are proposed for this project. A summary of the area tributary to each gravel-filled trench is shown below: Impervious Pervious Impervious Equivalent Length (SF) (SF) [I+P*(700/5000)] (FT) SF Gravel-Filled 2�gg6 1,199 3,154 46 Trench 1 Gravel-Filled Trench 2 2,671 571 2,751 40 I Gravel-Filled 1,996 676 2,041 30 � Trench 3 ' Total 7,653 2,446 7,996 116 Section C.2.4.4 of the KCSWDM states that the gravel trench size shall be designed at a ratio of ' 10 feet of trench per 700 SF impervious (or 5,000 SF pervious)tributary to the trench. Therefore, the length of each gravel-filled trench was determined by calculating the impervious equivalent tributary area to the gravel-filled trench. See Exhibit A-6 for the location of each gravel-filled trench. A minimum of approximately 80 feet of grass-vegetated flow path segment is provided upon discharge for each gravel trench, and thus exceeds the 25-foot minimum requirement. 2.4 CR 4-Conveyance System The three new double portable classrooms will include d�wnspouts that tie into roof drain systems prior to entering proposed catch basins and gravel-filled trenches 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 er�sion 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 more than 6 inches of freeboard between the design water surFace and structure grate during the 25-year peak storm event. N�severe flooding problems or severe erosion problems are created or aggravated in the 100-year storm event. See Appendix A-7 for the conveyance basin and calculations. 2.5 CR 5- Erosion and Sediment Control Onsite land disturbance will consist of clearing the work site (approximately 1y000 SF), small amounts of demolition, and regrading for placement of five catch basins, six area drains, and three gravel-filled trenches. Erosion and sediment control will be provided with the use of temporary and permanent seeding within the work limits, silt fence or wattles, and in�et sediment protection. A Temporary Erosion and Sedimentation Control Plan has been included in the plan set. See Section 8 for Construction Stormwater Pollution Prevention Plan (CSWPPP) Analysis and Designs. 2.6 CR 6- Maintenance and Operations Maintenance and operations of all drainage facilities will be maintained by the owner. The project proposes new area drains and catch basins onsite. See Appendix A-9 for the Operations and Maintenance Manual. Technical Information Report O Q O Q Maplewood Heights Elementary School Portables 3 . Project No. 2150095.10 2.7 CR 7 - Financial Guarantees and Liability This project will provide financial guarantees and liability per City of Renton requirements. See Appendix A-10 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 Special Requirement(SR) 1 -Other Adopted Requirements The project is included in the Lower Cedar River Drainage Basin. City and County basin I' 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-8 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 The project is not located within an aquifer protection zone. See Appendix A-11 for King County Districts and Development Conditions. 3.0 Offsite Analysis There are no upstream tributary areas contributing drainage to the basin area. 3.1 Task 1 —Study Area Definition and Maps Maplewood Heights Elementary School proposes to place three new portable buildings on the 8.67-acre site located at 130 Jericho Avenue SE in Renton, Washington. AHBL staff visited the site on March 18, 2015. The project site lies within the Lower Cedar River Drainage Basin, as delineated by the King County Water Features Map. There are no wetlands on or in the vicinity of the project site basin. The existing project site consists of four single classroom portables, one double classroom portable, five portable ramps, associated asphalt walks, a storage container, and grassed area. TecPhnical Info 9ation Report ry D Q . D Ma lewood Hei hts Elementa School Portables 4 Project No.2150095.10 The project site basin receives no upstream stormwater. In existing conditions, there is one discharge location from the project site. Stormwater from the existing portable roofs is conveyed via downspouts and splash blocks, and sheet flows 80 feet southwest through grassed area to SE 2`� Place. Stormwater flows west along the SE 2nd Place curb line. Stormwater enters a catch basin southwest of the project site on SE 2"d Place. Stormwater is then conveyed in an 8-inch pipe to a catch basin at the northeast c nor er of the intersection of SE 2"d Place and Jericho Avenue SE. Stormwater is then conveyed through an 18-inch concrete pipe through a series of catch basins west along 5,�,�"� Place, up to a storm manhole adjacent to the intersection of SE 2"a Place and Hoquiam Avenue. Stormwater is then conveyed to the south in a 48-inch pipe and outfalls to Maplewood Creek. 3.2 Task 2—Resource Review I The following resources were reviewed to discover any existing or potential problems in the study area: • Civil Engineering Plans: Maplewood Heights Elementary School, dated April 10, 1996, prepared by Waldron Pomeroy Smith Foote&Akira Architects. • FEMA Map: FEMA Flood Insurance Rate Map 53033C0982F, dated May 16, 1995, indicates that the project site lies within Zone X—areas determined to be outside the 500- year floodplain (see Exhibit A-8). • King County iMAP: The project site is not located in any of the following mapped critical areas: 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 • Soils Information: Site soils have been classified as medium dense to very dense Vashon lodgement till, overlain in places by fill (see Exhibit A-2), based on a Geotechnical Report dated March 16, 2015, prepared by Associated Earth Sciences, Inc. • City of Renton COR Maps: The downstream basins were delineated using the City of Renton COR Maps, along with a site visit on March 18, 2015. 3.3 Task 3—Field Inspection On March 18, 2015, AHBL staff performed a Downstream Analysis of the drainage system receiving stormwater runoff from the proposed portable classrooms at Maplewood Heights Elementary School. 1.

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 four single classroom portables, one double classroom portable, five portable ramps, associated asphalt walks, a storage container, and grassed area to the south. The project site area is 8.67 acres, with 4.11 acres of existing impervious coverage. 7. Collect information on pipe sizes, channel characteristics, drainage structures, and relevant critical areas (e.g., wetlands, stream, and steep slopes): Pipe sizes were determined by using survey information and City of Renton COR Maps. The pipe running downstream west along SE 2"d Place is an 18-inch pipe until reaching a manhole at the intersection of Hoquiam Avenue SE and SE 2"d Place, where the pipe is conveyed south in a 48-inch storm pipe. No critical areas were observed. 8. Verity 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 March 18, 2015. The weather was sunny and 60 degrees. 3.4 Task 4— Drainage System Description and Problem Descriptions The natural discharge location of stormwater for the project area is the grass field south of the existing portables. Stormwater will flow from the proposed portables to catch basins via roof ' drains and closed conveyance piping to three gravel-filled trenches along the south side of the proposed portables. Stormwater is�roposed to sheet flow from the gravel-filled trenches through a vegetated flow path toward SE 2" Place. Stormwater flows west along the SE 2�d Place curb line. Stormwater enters a catch basin southwest of the project site on SE 2nd Place. Stormwater is then conveyed in an 8-inch pipe to a catch basin at the northeast corner of the intersection of SE 2"d Place and Jericho Avenue SE. Stormwater is then conveyed through an 18-inch concrete pipe through a series of catch basins west along SE 2nd Place, up to a storm manhole adjacent to the intersection of SE 2"d Place and Hoquiam Avenue. Stormwater is then conveyed to the south in a 48-inch pipe and outfalls to Maplewood Creek. No signs of flooding, overtopping, or erosion were evident at the time of the inspection. 4.0 Flow Control and Water Quality Facility Analysis and Design See Sections 2.3 and 2.8 above for the Flow Control and Water Quality Analysis sections.

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 resutts 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 generalty 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 � 911 Fifth Avenue � Kirkland,WA 98D33 P � 425.827.7701 F� 425.827.5424 �verett Office � 2911%:Hewitt Avenue,Suite 2 � Everett,WA 98201 P � 425.259.0522 F � 425.252.3408 Taccma Office � 1552 Commerce Street,Suite 102 � Tacoma,WA 98402 P � 253.722.2992 F � 253.722.2993 www.aesgeo.com Portable Classroom Placements Renton School District Document Review Proposed placement durin� 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 possiblv durin� 2016 • Tiffany Park: 1601 Lake Youngs Way SE, Renton, Washington • Talbot Hill: 2300 Talbot Road South, Renton, Washington � Lakeridge: 7400 South 115`h Street, Seattle, Washington • Bryn Mawr: 8212 South 118`h 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. AE51 D�CUMENT 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 AE51 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 lanuary 2012 and January 2015. In summary,these explorations encountered medium dense to very dense Vashon Iodgement 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 ti(I 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. ip�;pc-K£150128A2-Pro,�ect5120:50I28��K£�WP Page 2 Portable Classroom P/acemenrs Renton Schoo!District Document Review Hazelwood Elementary Schooi 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 explaration 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 ASSOClATED EARTH SClFNCES,fNC. JP;./pc—KE:50;28A2—P;ojec[s�10150128�Ke"1WV Page 3 Portable Classroom Placements Renton Schoo!District Document Review explorations encountered medium dense to very dense Vashon lodgement till. Also, our review of the Geolog�c 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 p{aces by fill. The lodgement till and bedrock are generally cansidered suitable for foundation support of portable classroam 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 Apri) 1991, January 1993 and March 1994, and issued a letter dated Apri) 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 soii 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 revea! past AESI subsurface expforations 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 ASSOClATED EARTH SGENCES,INC.
