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 I 911 Fifth Avenue I Kirkland, WA 98033 P I 425.827.7701 F I 425.827.5424 Everett Office I 2911 'A Hewitt Avenue, Suite 2 I Everett, WA 98201 P I 425.259.0522 F I 425.252.3408 Tacoma Office I 1552 Commerce Street, Suite 102 I Tacoma, WA 98402 P I 253.722.2992 F I 253.722.2993 www.aesgeo.com 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\20150128\KE\WP Page 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. IPL/pc — KE150128A2— Projects\20150128\KE\WP Page 3 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. .181/pc— KE150128A2— Projects\20150128\KE\WP Page 4 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.
