EXECUTIVE SUMMARY: This project consists of the complete removal or cutting off of 24-18"x6"x±2O' wood sheet pile planks located on the upstream side (south side) of the Springbrook Creek/P-1 Channel box culvert crossing of Grady Way SW. The Grady Way box culvert was constructed in 1986 in accordance with the 1 1/24/85 Hydraulic Project Approval (HPA) permit, (see Figure 3) along with the required City and other regulatory agency permits. The box culvert construction was permitted under the USDA Soil Conservation Service 1979 Final and 1981 Supplemental EIS for the East Side Green River Watershed Phase I projects which the City of Renton adopted (see Figure 4). When construction of the Grady Way box culvert was completed, the sheet pile planks were not removed from the upstream end of the structure due to the fact that the upstream channel was not improved and future construction was expected to be forthcoming. In 1988, the City completed the Determination of Adequacy Study of the 1981 Soil Conservation Service (SCS) NEPA EIS which prompted the re-evaluation of the East Side Green River Watershed plan hydrology, hydraulics, and environmental elements (that is currently in progress) and prevented the previously anticipated upstream channel works. The revised preliminary hydrology and hydraulic modeling for the East Side Green River Watershed has identified the Grady box culvert as a significant restriction in the drainage systems conveyance. This is due to the sheet piles restricting the flows through the box culvert which causes a noticeable backwater effect in the upstream system during major storm events contributing to the upstream flooding in the valley and instream erosion. PROJECT LOCATION: i The project is located at the Springbrook Creek/P-1 Channel box culvert crossing of Grady Way SW in the northeast 1/4 of Section 24 of Township 23 North Range 4E in the City of Renton, King County, Washington. The site's general location is north of 1-405 and directly southwest of the intersection of Grady Way SW and i Oakesdale Avenue SW on the south side of Grady Way SW at the Springbrook Creek/P-1 Channel crossing. i i l � i • Grady Way Box Culver Page 2 CURRENT SITE CONDITIONS: The Grady Way box culvert is a reinforced concrete structure consisting of five cells. Cell #1 is on the west side of the box culvert looking downstream (north) at the upstream end of the Grady Way Box (see Figure 1 . - Reinforced concrete box culvert sections and Figure 2 - Project site photo). Cell #2 is currently the only cell open which has dimensions of approximately 14'x12' with its bottom 2' lower than the other cells for fish passage. The remaining cells (1 , 3, 4, and 5) are approximately 12' x 12' with bottom elevation of 2.09 NGVD and a maximum water line elevation of 14.0 NGVD. As shown in Figure 1 , Cell Nos. 1 , 3, and 4 are each blocked by eight 18"x6" sheet piles with lengths that vary but basically 20' long. Cell #5 has three sheet piles blocking it with the remaining portion buried. The sheet piles blocking the Grady Way box culvert are treated with creosote which are supported by 2"x1 " boards nailed together at the top and bottom of the sheet pile. Some have soil deposited against them. DESCRIPTION OF WORK, METHOD, AND EQUIPMENT: 3 The first fedr sheet piles west of Cell #2 blocking Cell #1 will be completely removed along with alf eight sheet pile in front of Cell #3. These twelve sheet piles will be loosened by removing the support boards by a person with a claw hammer or crow bar and lifted from their existing position with the use of a backhoe bucket or medium sized crane, a chain or cable. The work will be done from on top of the box culvert except where a person may need to enter the steam to remove the bottom support board, and to help loosen the lower ends of the sheet pile to assist in its removal. The sheet pile to be removed will be lifted vertically to minimize the disturbance of the sediment and every effort shall be made to prevent siltation from entering the water. All debris associated with the sheet pile will be removed from the stream. No equipment will enter the stream and no excavation will be done. The remaining four sheet pile on the west side of Cell #1 and the eight sheet piles located in front of Cell #4 will be sawed off at a maximum of one foot above the f ground with the use of a chain saw. The sheet pile will be cut individually following the removal of the top support board and only after the chain or cable connected to the backhoe bucket or crane has been fastened to the sheet pile with tension to provide support while the sheet pile is being cut. This will prevent the sheet pile from falling into the stream and provide safety for the person cutting the sheet pile with the chain saw. The individual sheet pile will then be lifted from its existing position with the use of the backhoe or crane located on top of the box culvert. i If any of the full size sheet pile that are to be removed in Cells #1 or #3 cannot be done without causing significant siltation of the surface water, it will be sawed off I above the water line and removed in the same manner as described for the sawed off sheet pile. All sheet pile, along with any other debris removed, will be placed on a flat bed truck or in a dump truck and hauled from the site for stock piling at the' City of Renton Maintenance Shop site or disposed of at an approved dump site. The three sheet pile blocking Cell #5 will not be removed, since their removal will not allow additional utilization of the box culverts constructed capacity until II f 0 Grady Way Box Culvert' Page 3 upstream channel improvements are completed. Care will be taken to minimize the disturbance of the existing vegetation located upstream from the box culvert and every effort shall be made to prevent siltation of the water. The project's duration will consist of a maximum of two working days. The work shall be performed by the City of Renton Stormwater maintenance crews, or an approved contractor with the equipment described. Technical, assistance or supervision will be provided by the City of Renton Stormwater Utility Engineering staff. PROJECT BENEFITS: The project will partially remove an identified restriction on the steams conveyance system and allow additional storm event peak flows to pass freely through the structure. This will allow better utilization of the existing box culverts constructed capacity and will-reduce the backwater effect caused by the existing restriction. This will help to reduce potential upstream flooding during major storm events. The removal of the creosoted soaked sheet pile will also eliminate a potential source of water quality contamination. If there are any questions regarding this project, please contact Ron Straka with the City of Renton Stormwater Utility Engineering at 277-5547.

Page 2 CURRENT SITE CONDITIONS: The Grady Way box culvert is a reinforced concrete structure consisting of five cells. Cell #1 is on the west side of the box culvert looking downstream (north) at the upstream end of the Grady Way Box (see Figure 1 . - Reinforced concrete box culvert sections and Figure 2 - Project site photo). Cell #2 is currently the only cell open which has dimensions of approximately 14'x12' with its bottom 2' lower than the other cells for fish passage. The remaining cells (1 , 3, 4, and 5) are approximately 12' x 12' with bottom elevation of 2.09 NGVD and a maximum water line elevation of 14.0 NGVD. As shown in Figure 1, Cell Nos. 1 , 3, and 4 are each blocked by eight 18"x6" sheet piles with lengths that vary but basically 20' long. Cell #5 has three sheet piles blocking it with the remaining portion buried. The sheet piles blocking the Grady Way box culvert are treated with creosote which are supported by 2"x1 " boards nailed together at the top and bottom of the sheet pile. Some have soil deposited against them. DESCRIPTION OF WORK, METHOD, AND EQUIPMENT: The first four sheet piles west of Cell #2 blocking Cell #1 will be completely removed along with all eight sheet pile in front of Cell #3. These twelve sheet piles will be loosened by removing the support boards by a person with a claw hammer or crow bar and lifted from their existing position with the use of a backhoe bucket or medium sized crane, a chain or cable. The work will be done from on top of the box culvert except where a person may need to enter the steam to remove the bottom support board, and to help loosen the lower ends of the sheet pile to assist in its removal. The sheet pile to be removed will be lifted vertically to minimize the disturbance of the sediment and every effort shall be made to prevent siltation from entering the water. All debris associated with the sheet pile will be removed from the stream. No equipment will enter the stream and no excavation will be done. The remaining four sheet pile on the west side of Cell #1 and the eight sheet piles located in front of Cell #4 will be sawed off at a maximum of one foot above the ground with the use of a chain saw. The sheet pile will be cut individually following the removal of the top support board and only after the chain or cable connected to the backhoe bucket or crane has been fastened to the sheet pile with tension to provide support while the sheet pile is being cut. This will prevent the sheet pile from falling into the stream and provide safety for the person cutting the sheet pile with the chain saw. The individual sheet pile will then be lifted from its existing position with the use of the backhoe or crane located on top of the box culvert. If any of the full size sheet pile that are to be removed in Cells #1 or #3 cannot be done without causing significant siltation of the surface water, it will be sawed off above the water line and removed in the same manner as described for the sawed off sheet pile. All sheet pile, along with any other debris removed, will be placed on a flat bed truck or in a dump truck and hauled from the site for stock piling at the' City of Renton Maintenance Shop site or disposed of at an approved dump site. The three sheet pile blocking Cell #5 will not be removed, since their removal will not allow additional utilization of the box culverts constructed capacity until i • • Grady Way Box Culver• . Page 3 upstream channel improvements are completed. Care will be taken to minimize the disturbance of the existing vegetation located upstream from the box culvert and every effort shall be made to prevent siltation of the water. The project's duration will consist of a maximum of two working days. The work shall be performed by the City of Renton Stormwater maintenance crews, or an approved contractor with the equipment described. Technical assistance or supervision will be provided by the City of Renton Stormwater Utility Engineering staff. PROJECT BENEFITS: The project will partially remove an identified restriction on the steams conveyance system and allow additional storm event peak flows to pass freely through the structure. This will allow better utilization of the existing box culverts constructed capacity and wily reduce the backwater effect caused by the existing restriction. This will help to reduce potential upstream flooding during major storm events. The removal of the creosoted soaked sheet pile will also eliminate a potential source of water quality contamination. If there are any questions regarding this project, please contact Ron Straka with the City of Renton Stormwater Utility Engineering at 277-5547.

EXECUTIVE SUMMARY: This project consists of the complete removal or cutting off of 24-18"x6"xt20' wood sheet pile planks located on the upstream side (south side) of the Springbrook Creek/P-1 Channel box culvert crossing of Grady Way SW. The Grady Way box culvert was constructed in 1986 in accordance with the 11/24/85 Hydraulic Project Approval (HPA) permit, (see Figure 3) along with the required City and other regulatory agency permits. The box culvert construction was permitted under the USDA Soil Conservation Service 1979 Final and 1981 Supplemental EIS for the East Side Green River Watershed Phase I projects which the City of Renton adopted (see Figure 4). When construction of the Grady Way box culvert was completed, the sheet pile planks were not removed from the upstream end of the structure due to the fact that the upstream channel was not improved and future construction was expected to be forthcoming. In 1988, the City completed the Determination of Adequacy Study of the 1981 Soil Conservation Service (SCS) NEPA EIS which prompted the re-evaluation of the East Side Green River Watershed plan hydrology, hydraulics, and environmental elements (that is currently in progress) and prevented the previously anticipated upstream channel works. The revised preliminary hydrology and hydraulic modeling for the East Side Green River Watershed has identified the Grady box culvert as a significant restriction in the drainage systems conveyance. This is due to the sheet piles restricting the flows through the box culvert which causes a noticeable backwater effect in the upstream system during major storm events contributing to the upstream flooding in the valley and instream erosion. PROJECT LOCATION: The project is located at the Springbrook Creek/P-1 Channel box culvert crossing of Grady Way SW in the northeast 1/4 of Section 24 of Township 23 North Range 4E in the City of Renton, King County, Washington. The site's general location is north of 1-405 and directly southwest of the intersection of Grady Way SW and Oakesdale Avenue SW on the south side of Grady Way SW at the Springbrook Creek/P-1 Channel crossing. • • Grady Way Box Culvert Page 2 CURRENT SITE CONDITIONS: The Grady Way box culvert is a reinforced concrete structure consisting of five cells. Cell #1 is on the west side of the box culvert looking downstream (north) at the upstream end of the Grady Way Box (see Figure 1 . - Reinforced concrete box culvert sections and Figure 2 - Project site photo). Cell #2 is currently the only cell open which has dimensions of approximately 14'x12' with its bottom 2' lower than the other cells for fish passage. The remaining cells (1, 3, 4, and 5) are approximately 12' x 12' with bottom elevation of 2.09 NGVD and a maximum water line elevation of 14.0 NGVD. As shown in Figure 1 , Cell Nos. 1, 3, and 4 are each blocked by eight 18"x6" sheet piles with lengths that vary but basically 20' long. Cell #5 has three sheet piles blocking it with the remaining portion buried. The sheet piles blocking the Grady Way box culvert are treated with creosote which are supported by 2"x1 " boards nailed together at the top and bottom of the sheet pile. Some have soil deposited against them. DESCRIPTION OF WORK, METHOD, AND EQUIPMENT: The first four sheet piles west of Cell #2 blocking Cell #1 will be completely removed along with all eight sheet pile in front of Cell #3. These twelve sheet piles will be loosened by removing the support boards by a person with a claw hammer or crow bar and lifted from their existing position with the use of a backhoe bucket or medium sized crane, a chain or cable. The work will be done from on top of the box culvert except where a person may need to enter the steam to remove the bottom support board, and to help loosen the lower ends of the sheet pile to assist in its removal. The sheet pile to be removed will be lifted vertically to minimize the disturbance of the sediment and every effort shall be made to prevent siltation from entering the water. All debris associated with the sheet pile will be removed from the stream. No equipment will enter the stream and no excavation will be done. The remaining four sheet pile on the west side of Cell #1 and the eight sheet piles located in front of Cell #4 will be sawed off at a maximum of one foot above the ground with the use of a chain saw. The sheet pile will be cut individually following the removal of the top support board and only after the chain or cable connected to the backhoe bucket or crane has been fastened to the sheet pile with tension to provide support while the sheet pile is being cut. This will prevent the sheet pile from falling into the stream and provide safety for the person cutting the sheet pile with the chain saw. The individual sheet pile will then be lifted from its existing position with the use of the backhoe or crane located on top of the box culvert. If any of the full size sheet pile that are to be removed in Cells #1 or #3 cannot be done without causing significant siltation of the surface water, it will be sawed off above the water line and removed in the same manner as described for the sawed off sheet pile. All sheet pile, along with any other debris removed, will be placed on a flat bed truck or in a dump truck and hauled from the site for stock piling at the City of Renton Maintenance Shop site or disposed of at an approved dump site.

STORM DRAINAGE/FLOOD CONTROL POLICIES 1984 Amendment of the Valley Comprehensive Plan * The East Side-Watershed Project should be completed in an incremental fashion as the most promising method of accomplishing large scale flood control in the Valley. * A management agreement involving all affected parties -- Renton, Kent, Tukwila, Auburn, King County, state and federal agencies -- and guaranteeing a firm outlet capacity for Springbrook Creek/Black River should be developed and adopted for the Green River. * Participation of the Soil Conservation Service in the P-1 Channel project should be maintained if feasible. * New development -- rezones, plats, site approvals, building permits -- adjacent to the P-1 Channel should be required to dedicate right-of-way for the project. * The alignment of the P-1 Channel, detention basins, and wetlands mitigation as indicated on the S.C.S. Land Rights Work Man, the P-I and P-9 Channels Vicinity Man, and the Environmental Mitigation Agreement should be established as the official location of the regional flood control improvements. Changes in such alignment should be made only for compelling engineering, environmental, or public financial reasons so that property owners and the public will be fully aware of project plans. * If the East Side Watershed Project or other large scale flood control system is not completed in a timely manner, this plan and the existing zoning for the Valley should be reviewed to determine if further intensive development should be permitted. * New development throughout the Valley should provide on-site and lateral storm drainage as part of the overall storm drainage plan for the Valley. * Development regulations and flood control solutions should involve properties throughout the Black River/Springbrook Creek Basin -- including upland areas. * The Panther Creek Wetland should be publicly acquired as an essential element in the East Side Watershed Project. * The Environmental Mitigation Agreement -- involving the Soil Conservation Service and local sponsors (Renton, Kent, Tukwila, and King County) -- of the East Side Watershed Project should be implemented in phase with developing the P-1 Channel system. * The Flood Hazard Ordinance should be administered on the basis of requiring compensating storage -- either on-site or within the P-1 Channel alignment -- for new development or landfill below the base flood elevations of the revised Flood Hazard Maps.
