Grady Way Renton, WA 98057 SSubject: Project Narrative for Additional (Phase 2) Geotechnical Borings, Utility Potholing, and Cultural Resources Exploration for the Tabor-Crowall and Brodell Revetment Repair Project To Whom it May Concern: The Tabor-Crowall and Brodell Revetment Repair Project (the Project) is a repair project at the Tabor-Crowall and Brodell revetments along the Cedar River within the City of Renton. See Attachment 1: Tabor-Crowall Revetment Repair – Cover Sheet and Vicinity Map (Sheet 1/A-001) and Brodell Revetment Repair - Cover Sheet and Vicinity Map (Sheet 1/B-001) for locations of the Tabor- Crowall and Brodell revetments, respectively. The Tabor-Crowall site is located in the southwest quarter of Section 16, Township 23 N, Range 05 E, W.M. The Brodell site is located in the northeast quarter of Section 21, Township 23 N, Range 05 E, W.M. All borings, potholes, and cultural resources explorations will occur within Riverview Park, on tax parcel 162305-9033 or within SR169 right-of-way (ROW). Previous geotechnical borings and utility potholing occurred in February 2023 for the Project under Phase 1, but additional geotechnical borings and utility potholing are needed as the design has been further developed. See Attachment 2 – shoreline and critical areas exemption – from those February 2023 activities for Phase 1. Proposed Phase 2 activities include geotechnical borings, cultural resources explorations, and utility potholing, as described in detail below. NNone of the borings, explorations, or potholes will be located below the ordinary high water mark (OHWM) of the Cedar River or within wetlands. Geotechnical Borings A total of three (3) geotechnical borings are proposed as part of this Phase 2. x One (1) of these borings is within the sidewalk along SR169 to the north of the Cedar River. This boring requires SR169 traffic control (ID: T1-24, Sheet 3/A-101). x Two (2) of these borings are located within Riverview Park across the river from SR169. Traffic control of SR169 is not required (ID: T2-24, Sheet 3/A-101; and ID: T3- 24, Sheet 4/A-102). See Attachment 3: Traffic Control Plans (TCPs) for these Phase 2 activities. The TCP shows a proposed temporary lane closure of the southernmost eastbound lane while the EXHIBIT A  !         2025_0527_rev02_projectnarrativecedarriverrightbankrevrepair.docx 2 geotechnical boring T1-24 right next to SR169 is performed. More information on access and approach for this boring T1-24 is included later in this letter. Utility locates using ground-penetrating radar (GPR) or other similar technology that does not require digging or disturbing the ground surface will also be conducted ahead of these geotechnical borings, both by activating the ‘One Call’ system and by APS (a vendor who is also performing the potholing). Cultural Resources Exploration Approximately ten (10) hand-dug cultural resources explorations are needed for this Project. Each hole will be approximately 3 feet deep. The area of these explorations is along the north side of SR169 between SE 5th Street and the parking lot for the Maplewood Golf Course. Utility locates using ground-penetrating radar (GPR) or other similar technology that does not require digging or disturbing the ground surface will also be conducted ahead of these cultural resources explorations, both by activating the ‘One Call’ system and by APS (a vendor who is also performing the potholing). Utility Potholing A total of twenty-four (24) utility potholes are proposed as part of this Phase 2. x Twelve (12) of these are planned near the Tabor-Crowall revetment on the right bank of the Cedar River on the south side, or within SR169. x Twelve (12) of these are planned near the Brodell revetment within/proximate to the Cedar River Trail along the south side of SR169. The proposed utility pothole locations are shown by color (storm/sewer = green, communications/power = red, water = blue). The design team is in contact with utility owners, including: The City of Renton, King County Wastewater Treatment Division (WTD), and Seattle Public Utilities (SPU), in addition to owners of the electrical and telecom utilities. See the TCP, which shows a proposed temporary lane closure while the utility potholes right along SR169 are performed. Utility locates using ground-penetrating radar (GPR) or other similar technology that does not require digging or disturbing the ground surface will also be conducted ahead of these potholes, both by activating the ‘One Call’ system and by APS (a vendor who is also performing the potholing). Also, APS will perform these utility locates (that do not require disturbance of the ground surface) on the left bank of the Cedar River across the river from the Brodell revetment (see page 5 of 5 in Attachment 3 for location). The purpose of these locates is to confirm the location of the SPU Water Transmission line on that side of the river. We request that the City of Renton allow APS to access that side of the river. EXHIBIT A  !         2025_0527_rev02_projectnarrativecedarriverrightbankrevrepair.docx 3 Per Renton Municipal Code (RMC) 4-3-050.C.3.4, site investigative work is an exempt activity within critical areas and buffers (which include the Cedar River buffer) if the work will not disturb more than 5% of the critical area or buffer. Impacts must also be minimized, and disturbed areas must be restored at a 1:1 ratio. The proposed project will meet these requirements. Per RMC 4-9-190.C. the project is an exempt activity under the Shoreline Master Program based on the following conditions: (1) The activity does not interfere with the normal public use of surface waters; (2) The activity will have no significant adverse impact on the environment including, but not limited to fish, wildlife, fish or wildlife habitat, water quality, and aesthetic values; (3) The activity does not involve the installation of a structure and upon completion of the activity the vegetation and land configuration of the site are restored to conditions existing before the activity; (4) A private entity seeking development authorization under the Shoreline Master Program first posts a performance bond or provides other evidence of financial responsibility to the Planning Division to ensure that the site is restored to pre-existing conditions; (5) The activity is not subject to the permit requirements of RCW 90.50.550. TThese proposed activities will be conducted as follows: 1. UUTILITY LOCATES: An 811 One-Call will be initiated at geotechnical boring locations, utility potholing locations, and at locations of cultural resources hand-dug exploration locations ahead of those activities (see items 2, 3, and 4 below). Applied Professional Services (APS) (under contract with Jacobs) will, in parallel, perform private utility locates at these locations, placing paint on the pavement and/or turf to mark utilities. (NOTE: These utility locates do not require disturbance of ground surface.) 2. GGEOTECHNICAL BORINGS: Holocene (geotechnical driller) will perform geotechnical borings with the oversight of Jacobs. See the site plan for planned locations, which are all three (3) at Tabor-Crowall. Borings will be approximately 8 inches wide. All soil will be stockpiled adjacent to the borehole and replaced upon completion of the work. Access, Traffic Control, Vegetation Impacts/Restoration for Geotechnical Borings: x Tabor-Crowall Cedar River right bank (sidewalk next to SR169): One (1) boring (see Attachment 1, boring ID: T1-24) up to 80 feet in depth will be conducted within the sidewalk next to SR169. A temporary lane closure is requested to perform this boring of the eastbound curb lane. See attached TCP for vehicle and pedestrian closures/detours. It is anticipated that the lane closure could be up to six (6) hours. It is anticipated that this temporary lane closure would happen in the morning hours and be demobilized ahead of the afternoon rush hour on SR169. Holocene will access the location via the SR169 roadway from Riverview Park. No vegetation will be impacted by these activities. The area will then be restored to its current condition. (Anticipated duration: 6 hours) EXHIBIT A  !         2025_0527_rev02_projectnarrativecedarriverrightbankrevrepair.docx 4 x Tabor-Crowall Cedar River left bank (Riverview Park): Two (2) borings (see Attachment 1, boring ID: T2-24 and T3-24) up to 30 feet in depth will be conducted within Riverview Park on the left bank of the Cedar River (across the river from SR169). A Jacobs archaeologist will be present to observe borings and note if any cultural resources are discovered during boring activities. Holocene will access the locations with a tracked vehicle via the Cedar River Trail railroad bridge. No Cedar River Trail or roadway closures are required for these borings, but spotters will be used both during borings and also during access via the Cedar River Trail. Temporary fencing will be used during these activities and removed afterwards. Boring locations are next to the forested riparian vegetation just south of the river. Vegetation in this area includes Douglas fir, red alder, and Himalayan blackberry. Minor shrub or tree pruning may be necessary for this boring, but tree removal will not be necessary. Park users will be instructed to avoid the two nearby benches. The area will then be restored to current conditions. (Anticipated duration: 4 hours each boring, anticipate both during one (1) day) x 3. UUTILITY POTHOLING: APS, with the oversight of Jacobs, will perform utility potholing. See Attachment 1 for planned locations. (Anticipated duration: several working days. We can schedule for certain times of day or days of the week, depending on City of Renton requirements. We anticipate working with the City to schedule these, timing them to minimize impacts.) Method of Potholing: Potholing will be accomplished by using one of two methods – shallow or deep – depending on the anticipated depth of the utility: x Shallow (for storm/sewer [green], communications [red] potholes: by a vacuum mounted on the back of small pick-up truck and the hole is typically less than 8 inches wide. All excavated material will be replaced upon completion of work. The area will then be restored to its current condition. x Deep (for water [blue] specifically the SPU water transmission line): by hydrovac excavation; hole is typically 8-10 inches wide. Excavated material will be replaced with new backfill material, and removed material will be hauled and disposed of. The area will then be restored to its current condition. Access, Traffic Control, Vegetation Impacts/Restoration for Potholing: x Tabor-Crowall: Potholing for communications/electrical (red) will occur using a vacuum mounted on the back of a small pick-up truck. Potholes next to SR169 will be performed during traffic control setup per Attachment 3 (with lane closure). Potholing for storm (green) may require opening a storm maintenance hole lid in the travel lane; therefore, this work will also need to be performed during lane closure. See Attachment 3 for lane closure plan and pedestrian detour/access plan. EXHIBIT A  !         2025_0527_rev02_projectnarrativecedarriverrightbankrevrepair.docx 5 No vegetation will be impacted by these activities. The area will then be restored to its current condition. x Brodell: Traffic control setup will be required for potholes next to SR169 per Attachment 3 (with lane closure). Access to the pothole locations along the Cedar River Trail will be via the trail just to the west, from the eastbound travel lane on SR169. This is the same access location that was used for borings and potholing at this location in February 2023. See Attachment 3 for lane closure plan and pedestrian detour/access plan. Minor shrub and tree pruning will be required at this location to perform the communications (red) potholing along SR169, and possibly some to accomplish the water (blue) potholing along the trail next to the Cedar River. The area will then be restored to its current condition. 4. CCULTURALL RESOURCESS EXPLORATIONS: Jacobs will perform shallow hand-dug holes needed to inform the cultural resources assessment. See Attachment 1 for planned locations, all along the proposed Cedar River Trail detour, north of SR169. No traffic control or details are required for this work. No trees or shrubs will be removed or pruned for this work. All soil will be stockpiled adjacent to the hole and replaced upon completion of the work. (Anticipate duration: 2-3 days of work. We can limit to specific times of day or days of the week per City of Renton requirements.) King County Water and Land Resources (WLRD) Division has hired Jacobs as the design consultant for this work. Subconsultants and vendors under contract with Jacobs include Herrera (permitting support), APS (traffic control, utility potholing), Kleinfelder (laboratory analysis of geotech boring samples) and Holocene (geotech driller).

PROJECT DESCRIPTION: The applicant is requesting a Shoreline Exemption and Critical Areas Exemption for Phase 2 Geotechnical Borings, Utility Potholing, and Cultural Resources Exploration for the Tabor-Crowall and Brodell Revetment Repair Project. The Tabor-Crowall and Brodell Revetment Repair Project is a repair project at the Tabor-Crowall and Brodell revetments along the Cedar River. Phase 1 Geotechnical Borings and Utility Potholing occurred under LUA23-000048 in February 2023. Additional geotechnical borings and utility potholing are now needed as the project design has been further developed. A total of three (3) geotechnical borings are proposed. One (1) of these borings is within the sidewalk along the south side of SR169 to the north of the Cedar River. Two (2) of these borings are located within Riverview Park on the south side of the Cedar River. Approximately ten (10) hand-dug cultural resources explorations are proposed. The area of these explorations is proposed along the north side of SR 169 between SE 5th St and the parking lot for the Maplewood Golf Course. A total of twenty-four (24) utility potholes are proposed. Twelve (12) of these are proposed near the Tabor-Crowall revetment on the right bank of the Cedar River on the south side, or within SR 169. The other twelve (12) are proposed near the Brodell revetment within or proximate to the Cedar River Trail along the south side of SR 169. None of the borings, explorations, or potholes would be located below the ordinary high-water mark (OHWM) of the Cedar River or within wetlands.

Grady Way Renton, WA 98057 Subject: Project Narrative for Additional (Phase 2) Geotechnical Borings, Utility Potholing, and Cultural Resources Exploration for the Tabor-Crowall and Brodell Revetment Repair Project To Whom it May Concern: The Tabor-Crowall and Brodell Revetment Repair Project (the Project) is a repair project at the Tabor-Crowall and Brodell revetments along the Cedar River within the City of Renton. See Attachment 1: Tabor-Crowall Revetment Repair – Cover Sheet and Vicinity Map (Sheet 1/A-001) and Brodell Revetment Repair - Cover Sheet and Vicinity Map (Sheet 1/B-001) for locations of the Tabor- Crowall and Brodell revetments, respectively. The Tabor-Crowall site is located in the southwest quarter of Section 16, Township 23 N, Range 05 E, W.M. The Brodell site is located in the northeast quarter of Section 21, Township 23 N, Range 05 E, W.M. All borings, potholes, and cultural resources explorations will occur within Riverview Park, on tax parcel 162305-9033 or within SR169 right-of-way (ROW). Previous geotechnical borings and utility potholing occurred in February 2023 for the Project under Phase 1, but additional geotechnical borings and utility potholing are needed as the design has been further developed. See Attachment 2 – shoreline and critical areas exemption – from those February 2023 activities for Phase 1. Proposed Phase 2 activities include geotechnical borings, cultural resources explorations, and utility potholing, as described in detail below. NNone of the borings, explorations, or potholes will be located below the ordinary high water mark (OHWM) of the Cedar River or within wetlands. We request a shoreline/critical areas exemption to perform all three of these geotechnical borings on May 22 and 23, 2025 because of the availability and scheduling of Holocene as the geotechnical driller. Should the City of Renton not want this team to conduct the T1-24 boring (see Attachment 1 for location) that requires a lane closure on these dates ahead of the Memorial Day weekend, we could perform that T1-24 boring at a later date and instead focus on T2-24 and T3- 24 on these days (traffic control of SR169 not needed for T2-24 and T3-24). Geotechnical Borings A total of three (3) geotechnical borings are proposed as part of this Phase 2.

This boring requires SR169 traffic control (ID: T1-24, Sheet 3/A-101). x Two (2) of these borings are located within Riverview Park across the river from SR169. Traffic control of SR169 is not required (ID: T2-24, Sheet 3/A-101; and ID: T3- 24, Sheet 4/A-102). See Attachment 3: Traffic Control Plans (TCPs) for these Phase 2 activities. The TCP shows a proposed temporary lane closure of the southernmost eastbound lane while the geotechnical boring T1-24 right next to SR169 is performed. More information on access and approach for this boring T1-24 is included later in this letter. Cultural Resources Exploration Approximately ten (10) hand-dug cultural resources explorations are needed for this Project. The area of these explorations is along the north side of SR169 between SE 5th Street and the parking lot for the Maplewood Golf Course. Utility Potholing A total of twenty-four (24) utility potholes are proposed as part of this Phase 2. x Twelve (12) of these are planned near the Tabor-Crowall revetment on the right bank of the Cedar River on the south side, or within SR169. x Twelve (12) of these are planned near the Brodell revetment within/proximate to the Cedar River Trail along the south side of SR169. The proposed utility pothole locations are shown by color (storm/sewer = green, communications/power = red, water = blue). The design team is in contact with utility owners, including: The City of Renton, King County Wastewater Treatment Division (WTD), and Seattle Public Utilities (SPU), in addition to owners of the electrical and telecom utilities. See the TCP, which shows a proposed temporary lane closure while the utility potholes right along SR169 are performed. Per Renton Municipal Code (RMC) 4-3-050.C.3.4, site investigative work is an exempt activity within critical areas and buffers (which include the Cedar River buffer) if the work will not disturb more than 5% of the critical area or buffer. Impacts must also be minimized, and disturbed areas must be restored at a 1:1 ratio. The proposed project will meet these requirements. Per RMC 4-9-190.C. the project is an exempt activity under the Shoreline Master Program based on the following conditions: (1) The activity does not interfere with the normal public use of surface waters; (2) The activity will have no significant adverse impact on the environment including, but not limited to fish, wildlife, fish or wildlife habitat, water quality, and aesthetic values; (3) The activity does not involve the installation of a structure and upon completion of the activity the vegetation and land configuration of the site are restored to conditions existing before the activity; (4) A private entity seeking development authorization under the Shoreline Master Program first posts a performance bond or provides other evidence of financial responsibility to the Planning Division to        (;+,%,7$$77$&+0(17  !         2025_0507_rev02_projectnarrativecedarriverrightbankrevrepair.docx 3 ensure that the site is restored to pre-existing conditions; (5) The activity is not subject to the permit requirements of RCW 90.50.550. These proposed activities will be conducted as follows: 1. UUTILITY LOCATES: An 811 One-Call will be initiated at geotechnical boring locations, utility potholing locations, and at locations of cultural resources hand-dug exploration locations ahead of those activities (see items 2, 3, and 4 below). Applied Professional Services (APS) (under contract with Jacobs) will, in parallel, perform private utility locates at these locations, placing paint on the pavement and/or turf to mark utilities. (NOTE: These utility locates do not require disturbance of ground surface.) 2. GGEOTECHNICAL BORINGS: Holocene (geotechnical driller) will perform geotechnical borings with the oversight of Jacobs. See the site plan for planned locations, which are all three (3) at Tabor-Crowall. Borings will be approximately 8 inches wide. All soil will be stockpiled adjacent to the borehole and replaced upon completion of the work. Access, Traffic Control, Vegetation Impacts/Restoration for Geotechnical Borings: x Tabor-Crowall Cedar River right bank (sidewalk next to SR169): One (1) boring (see Attachment 1, boring ID: T1-24) up to 80 feet in depth will be conducted within the sidewalk next to SR169. A temporary lane closure is requested to perform this boring of the eastbound curb lane. See attached TCP for vehicle and pedestrian closures/detours. It is anticipated that the lane closure could be up to six (6) hours. It is anticipated that this temporary lane closure would happen in the morning hours and be demobilized ahead of the afternoon rush hour on SR169. Holocene will access the location via the SR169 roadway from Riverview Park. No vegetation will be impacted by these activities. The area will then be restored to its current condition. x Tabor-Crowall Cedar River left bank (Riverview Park): Two (2) borings (see Attachment 1, boring ID: T2-24 and T3-24) up to 30 feet in depth will be conducted within Riverview Park on the left bank of the Cedar River (across the river from SR169). A Jacobs archaeologist will be present to observe borings and note if any cultural resources are discovered during boring activities. Holocene will access the locations with a tracked vehicle via the Cedar River Trail railroad bridge. No Cedar River Trail or roadway closures are required for these borings, but spotters will be used both during borings and also during access via the Cedar River Trail. Temporary fencing will be used during these activities and removed afterwards. Boring locations are next to the forested riparian vegetation just south of the river. Vegetation in this area includes Douglas fir, red alder, and Himalayan blackberry. Minor shrub or tree pruning may be necessary for this boring, but tree removal will not be necessary. Park users will be instructed to avoid the two nearby benches. The area will then be restored to its current condition.

See Attachment 1 for planned locations. Method of Potholing: Potholing will be accomplished by using one of two methods – shallow or deep – depending on the anticipated depth of the utility: x Shallow (for storm/sewer [green], communications [red] potholes: by a vacuum mounted on the back of small pick-up truck and the hole is typically less than 8 inches wide. All excavated material will be replaced upon completion of work. The area will then be restored to its current condition. x Deep (for water [blue] specifically the SPU water transmission line): by hydrovac excavation; hole is typically 8-10 inches wide. Excavated material will be replaced with new backfill material, and removed material will be hauled and disposed of. The area will then be restored to its current condition. Access, Traffic Control, Vegetation Impacts/Restoration for Potholing: x Tabor-Crowall: Potholing for communications/electrical (red) will occur using a vacuum mounted on the back of a small pick-up truck. Potholes next to SR169 will be performed during traffic control setup per Attachment 3 (with lane closure). Potholing for storm (green) may require opening a storm maintenance hole lid in the travel lane; therefore, this work will also need to be performed during lane closure. See Attachment 3 for lane closure plan and pedestrian detour/access plan. No vegetation will be impacted by these activities. The area will then be restored to its current condition. x Brodell: Traffic control setup will be required for potholes next to SR169 per Attachment 3 (with lane closure). Access to the pothole locations along the Cedar River Trail will be via the trail just to the west, from the eastbound travel lane on SR169. This is the same access location that was used for borings and potholing at this location in February 2023. See Attachment 3 for lane closure plan and pedestrian detour/access plan. Minor shrub and tree pruning will be required at this location to perform the communications (red) potholing along SR169, and possibly some to accomplish the water (blue) potholing along the trail next to the Cedar River. The area will then be restored to its current condition. 4. CCULTURAL RESOURCES EXPLORATIONS: Jacobs will perform shallow hand-dug holes needed to inform the cultural resources assessment. See Attachment 1 for planned locations, all along the proposed Cedar River Trail detour, north of SR169. No traffic control or details are required for this work. No trees or shrubs will be removed or pruned for this work. All soil will be stockpiled adjacent to the hole and replaced upon completion of the work.
