(Golder) is pleased to submit to Careaga Development (Careaga) this letter report documenting the results of our underground coal mine hazard assessment for the property you are considering for development in Renton. Washington (Site). We understand you are still in the process of feasibility assessments for the development and have received comments from the City of Renton (City) stating that the Site was adjacent to a mapped coal mine hazard zone and therefore a geotechnical coal mine hazard study is required. This report is intended to fulfill the City requirement for a coal mine hazard study. Depending on the depth of the mined seams. access slopes. and other factors, abandoned mines can present a potential hazard to surface structures due to regional ground or trough settlement, differential settlement, and sinkhole formation. Based on our assessment of the existing mine maps, publications and geologic conditions present, we conclude that the subject site is located in a medium coal mine hazard zone as strictly defined by the City Municipal Code 4-3-050. The Site is not underlain by any mapped or known coal mine workings, but due to the orientation of the adjacent coal seam the Site may be potentially affected by future mining-related subsidence. Due to the steep dip and orientation of the mined coal seams {dipping down to the south) there is a low risk of regional or trough subsidence that may extend onto the Careaga Site. We believe the risk of subsidence at the Site is low and that modest engineering mitigations can be incorporated into the project design to mitigate this risk. Please find accompanying this letter report a map of the subject site with an overlay of the nearest underground mine map (Figure 1 ), and a cross section (Figure 2) providing our conceptual interpretation of the subsurface geologic and mining conditions present adjacent to the Site. 1.0 BACKGROUND Portions of the City are underlain by shallow bedrock that contains several coal seams that were commercially mined below ground from the late 1800s until the 1950s. The approximate location of abandoned coal mines in Renton was researched and mapped in the 1960s and 1970s using historical mine maps. A comprehensive inventory report of the mines was completed in 1985 (Morrison Knudsen 1985). The information from those earlier studies, along with additional information on the overburden thickness (thickness of soil/rock cover over the mine working}, was used by the City to create coal mine hazard map folios. The maps indicate areas underlain by coal mines and provide a relative hazard designation (low, moderate, and severe}. A fourth term is used only on the City map folio ('unclassified"). In discussions with City staff. we understand the term "unclassified" means that abandoned mines are m<>nm,rl hut no investiqation was completed to rank the hazard designation. In simplified terms. the EXHIBIT 7 Golder AssociatH Inc. 18300 NE Union Hill Road, Suite 200 Redmond, WA 9a052 USA 1 8a3-0n7 Fax: (425) 882-5498 www.golder.com Golder Assoc1.itas: upernuun::, in Africa, Asia, Australasia, Europe.

The new facility would serve as a rehabilitation center which provides a 24-hour skilled nursing service to help people recover from disabilities. The completed facility would have 60 beds and approximately 72 employees. The subject property is located on the southeast corner of SE 174th St and 106th Place SE. The project work area totals 1. 76 acres and is zoned Commercial Arterial (CA) and is located in the Commercial Mixed Use (CMU) Comprehensive Plan Land Use Designation. The site is currently vacant with a coffee stand and existing access road on the south side of the site. The existing coffee stand is proposed to be removed. Access is proposed via 106th Place SE with an additional connection to the neighboring commercial property to the east. The proposal includes 56 surface parking stalls to the south and east of the building. The Traffic Impact Analysis was completed by Concord Engineering (dated October 21, 2015). The report included information that the proposed project is estimated to generate a total of 422 new weekday daily trips (211 entering, 211 exiting), 41 new trips occurring during the weekday PM peak hour {21 entering, 20 existing), and 31 new trips occurring during the weekday PM peak hour (22 entering, 9 existing).
