DEPARTMENT OF COMMUN . AND ECONOMIC DEVELOPMENT DATE: PROJECT NUMBER: PROJECT NAME: PROJECT MANAGER: CONTACT: LOCATION: DESCRIPTION: PLANNING DIVISION CERTIFICATE OF EXEMPTION FROM CRITICAL AREAS REGULATIONS EVALUATION FORM & DECISION February 08, 2017 LUA16-000963 Lake to Sound Trail CAE Matt Herrera, Senior Planner Jason Rich, King County Parks 201 S Jackson St Rm 700 Seattle, WA 981043855 550 MONSTER RD SW King County is requesting a Critical Areas Exemption to construct a pedestrian bridge across the Black River as part of the Lake to Sound Trail project. The bridge will be located approximately ISO-feet east of the Monster Rd bridge on parcels 722950-0281 and 377920-0090 or 550 Monster Rd. SW. Construction of the bridge supports would be located in a Geologically Hazardous Area. The proposed pedestrian bridge is prefabricated steel girder construction approximately 1l0-feet long and 12-feet wide and will allow trail users to cross the Black River separately from vehicle traffic. Construction activity includes constructing the foundation system on the banks of the Black River and then hoisting the bridge span with a crane to place it on the foundation. All proposed work would occur landward of the Ordinary High Water Mark. The Lake to Sound Trail project was granted Shoreline Substantial Development, Shoreline Conditional Use, and Shoreline Variance permit approval for the alignment with the pedestrian bridge on March 2,2016. The City Hearing Examiner included a condition of approval that required the applicant apply for a Certificate of Exemption for the bridge foundational supports as the construction plans indicated the supports may be within an area of protected slopes. The applicant's Geotechnical Report for the proposed bridge construction has identified deep liquefiable soils that are prone to settlement and lateral spreading during a seismic event. The report recommends a deep soil mixing method that will improve soil structure and create columns of stabilized soil that the bridge foundations can be constructed. Compaction of the slope and restoration would occur following construction of the foundation to maintain long term stability.

In response to examiner 20 questions, Vanessa Dolbee, Renton planning manager, noted that although the wetland impacts are addressed through shoreline regulations, compliance with all shoreline regulations would assure compliance with any applicable critical area regulations if critical area regulations were applied to the proposal. Mr. Sorenson noted that the proposed trail will not go beyond the footprint of the existing trail. He also confirmed that the proposed trail improvements will not adjoin any residences. 21 22 23 Jason Rich, applicant, noted that the applicant has exceeded tree replacement standards. In response 24 to examiner questions, Jenny Bailey, applicant engineer, clarified that the 1000 most westerly feet are within the floodplain and that there is a net cut within the floodplain such that storage capacity is increased by the project. 25 26 SSDP, CU and Variance -I DEPARTMENT OF COMMUI\ AND ECONOMIC DEVELOPMENT ----".,..,..-*Ren ton ® DATE: PROJECT NUMBER: PROJECT NAME: PROJECT MANAGER: CONTACT: LOCATION: DESCRIPTION: I J PLANNING DIVISION CERTIFICATE OF EXEMPTION FROM CRITICAL AREAS REGULATIONS EVALUATION FORM & DECISION February 07,2017 LUA16-000963 Lake to Sound Trail CAE Matt Herrera, Senior Planner Jason Rich, King County Parks 201 S Jackson St Rm 700 Seattle, WA 981043855 550 MONSTER RD SW CONCURR~NCE DATL2:;j~ UJ i7 King County is requesting a Critical Areas Exemption to construct a pedestrian bridge across the Black River as part of the Lake to Sound Trail project.
