These areas are analyzed as separate Threshold Drainage Areas (TDA 1 and TDA 2) as shown in Figures 1 through 3 and described below. Project plans showing the site characteristics are provided in Appendix I. Figure 1 – Vicinity Map TIR – Renton SW 19th Street Road Widening and SW 16th Street Roundabout 2 TDA 1 Project improvements within TDA 1 are associated with the widening of a portion of Renton SW 19th Street and will affect its intersection with Raymond Avenue. The approximate limit of work is shown in Figure 2. Improvements may include, but are not limited to, installation of AC pavement, installation of sidewalk, installation of three new pedestrian ramps, installation of storm drain and catch basins and installation of curb and gutter. The area of created or replaced impervious areas totals 4,400 SF. An additional 7,200 SF of existing asphalt will receive a grind and overlay. This is included in disturbed area calculations but not as replaced impervious area. Road and Pavement Design An interim widening was constructed while awaiting final design. This additional widening continues from the as-designed temporary condition. Based on feedback received from the city of Renton, the pavement section for the additional widening was to match the interim section of 3” of HMA over 6” of base material. Storm Drainage The stormwater drainage design in the proposed condition matches the existing condition, runoff in and around the area will enter the MS4 via existing catch basins on the site. This project proposes two catch basins as a measure to mitigate ponding, but these measures will not significantly impact the existing drainage pattern. Once the stormwater enters the MS4 via the existing or proposed nearby catch basins, it is routed to and discharged into the nearby Black River to the west. Figure 2 – TDA1 Site Location Map TIR – Renton SW 19th Street Road Widening and SW 16th Street Roundabout 3 TDA 2 Project improvements within TDA 2 are associated with the construction of a compact roundabout at the intersection of Renton SW 16th Street and Raymond Avenue. The approximate limit of work is shown in Figure 3. Roundabout construction includes, but is not limited to, installation of AC pavement, installation of sidewalk, installation of eight new pedestrian ramps, and installation of curb and gutter. The area of created or replaced impervious areas totals 6,400 SF. An additional 21,800 SF of existing asphalt will receive a grind and overlay. This is included in disturbed area calculations but not as replaced impervious area. Storm Drainage The stormwater drainage design in the proposed condition matches the existing condition, runoff in and around the area will enter the MS4 via existing catch basins at all four corners of the intersection. This project will adjust the location of the catch basin at the northeast corner to accommodate a proposed pedestrian ramp, but this will not significantly impact the existing drainage pattern. Once the stormwater enters the MS4 via the nearby catch basins, travels west in underground pipe beneath SW 16th Street for approximately 1,200 feet before discharging into the nearby Black River just west of Oakesdale Avenue. Figure 3 – TDA2 Site Location Map 16th TIR – Renton SW 19th Street Road Widening and SW 16th Street Roundabout 4 1.1 Soils The project is located in an urban, industrial area. The Natural Resources Conservation (NRCS) soil survey indicates the soil within TDA1 is made up of Woodinville silt loam (Wo). The area downstream of the discharge point encompassing the Black River is made up of Puyallup fine sandy loam (Py). Within TDA2, the entire project and surrounding area is defined as Urban Land (Ur) . The soil types in the project area are shown in Figure 4 and the geotechnical investigation performed by NV5 (August 2, 2022) is provided in Appendix B. TIR – Renton SW 19th Street Road Widening and SW 16th Street Roundabout 5 Figure 4 – Soil Map TIR – Renton SW 19th Street Road Widening and SW 16th Street Roundabout 6 2.0 Conditions and Requirements Summary The stormwater design will adhere to the requirements of the following codes and standards: 2022 City of Renton Surface Water Design Manual (RSWDM) Section 1.1, Drainage Review Section 1.1.2.4, Full Drainage Review Section 1.2, Nine Core Requirements Section 1.3, Six Special Requirements City of Renton Standard Details Since the project will create more than 2,000 square feet of new plus replaced impervious surface, a full drainage review is required. According to Table 1.1.2.A of the RSWDM, all nine core requirements and all six special requirements apply under a full review except where exemptions occur. There are 2 threshold drainage areas (TDAs) within the scope of this report, each of which has been analyzed separately. See Table 1.a and 1.b below for a summary of the TDAs and specific core and special requirements that apply. Table 1.a Threshold Discharge Area Summary TDA New PGIS (SF) Total New Impervious Surface (SF) Core Requirements #1 – Discharge at Natural Location #2 - Offsite Analysis #3 - Flow Control Facilities #4 Conveyance System #5 – Construction Pollution prevention #6 – Maintenance & Operations #7 - Financial Guarantees and Liability 8# - Water Quality Facilities #9 - On-site BMPs 1 2567 2567 Yes Yes No Yes Yes Yes Yes No No 2 0 605 Yes No No No Yes Yes Yes No No TIR – Renton SW 19th Street Road Widening and SW 16th Street Roundabout 7 Table 1.b Threshold Discharge Area Summary TDA New PGIS (SF) Total New Impervious Surface (SF) Special Requirements #1 – Other Adopted Area-Specific Requirements #2 – Flood Hazard Area Delineation #3 Flood Protection Facilities #4 - Source Control #5 – Oil Control #6 – Aquifer Protection Area 1 2567 2567 No Yes No No No No 2 0 605 No No No No No No TIR – Renton SW 19th Street Road Widening and SW 16th Street Roundabout 8 3.0 Offsite Analysis An offsite analysis has been performed for TDA-1. TDA-2 is exempt as it proposes less than 2,000 square feet of new impervious surface. A preliminary Level 1 Downstream Analysis was performed per Core Requirement #2 of the 2022 City of Renton SWDM to identify and evaluate any potential offsite flooding, erosion, and water quality problems that could be aggravated by the proposed project. There were no reported problems identified under Task 2 to investigate downstream of the site. There were no observed existing or potential issues of flooding, erosion, or water quality issues at the discharge location at the time of the field visit. Underground storm drains were not visible for inspection. TDA-1 is a small area that contributes to a very large tributary area that drains into the nearby Black River and is not expected to impact the existing downstream condition. Downstream drainage maps are provided in Appendix E. An important item of note is that an existing wetland is located directly across the street from this project’s area of work. This wetland will be protected in place and will not be impacted by the new development. Downstream Drainage Problems Requiring Special Attention Conveyance System Nuisance Problem (Type 1) No conveyance system nuisance problems are anticipated. The area of TDA-1 is a small area that contributes to a very large tributary area. Runoff from TDA-1 is collected via one proposed and one existing catch basin that directly feeds into an existing 60” pipe. An additional catch basin and 8” PVC pipe is proposed at the northwest corner of the intersection of 19th Street and Raymond Avenue. This will resolve a minor existing ponding issue where a new pedestrian ramp is being proposed but will not contribute significantly to runoff. Severe Erosion Problem (Type 2) No severe erosion problem is expected as there are no erosion-sensitive open drainage features in TDA-1, and no erosion risks were determined in the nearby Black River, the discharge point of the storm drainage network of the industrial area surrounding TDA-1. Severe Flooding Problem (Type 3) No severe flooding problem has been identified. FEMA has determined the entirety of the TDA- 1 project to be within Zone AE, A special flood hazard area, as shown in Figure 5. Base flood elevations in the project area are approximately 19-20’. Improvement elevations vary from 19.33 to 22.46 as shown on the project plans in Appendix I so significant roadway flooding is not anticipated. TIR – Renton SW 19th Street Road Widening and SW 16th Street Roundabout 9 Potential Impacts to Wetlands Hydrology (Type 4) Although there are wetlands downstream of the discharge location, the area of TDA-1 is a small area that contributes to a very large tributary area. The area of the overall drainage basin that contributes to the discharge location is approximately 57 acres as shown in Appendix G. The total new impervious area to be added as part of TDA-1 is 2,567 square feet which represents 0.1% of the overall basin area and is not expected to impact the existing wetlands. TIR – Renton SW 19th Street Road Widening and SW 16th Street Roundabout 10 Figure 5 – Flood Panel Information TIR – Renton SW 19th Street Road Widening and SW 16th Street Roundabout 11 4.0 Flow Control, Water Quality Facility Analysis, and Onsite BMPs TDA 1 proposes less than 5,000 square feet of new plus replaced impervious surface and less than 0.75 acres of new pervious surface. Flow control and water quality facilities will not be required based on the guidelines identified in section 1.2.3 of the City of Renton SWDM. TDA 2 proposes approximately 6,400 square feet of new plus replaced impervious area, the majority of which is the replacement of asphalt that being removed within sawcut limits to allow for the construction of new curb and gutters. As this exceeds 5,000 square feet, TDA 2 is not eligible for a Basic Exemption. TDA 2 is located in an area requiring the peak flow control standard to be met per subsection A of 1.2.3.1 of the RSWDM. Calculations were prepared to compare 100-year peak flow rate in the existing vs the proposed condition as provided in Appendix H. It was determined that the additional 574 square feet of impervious area in the proposed condition will result in an approximately 0.03 cfs increase. As this is below 0.15 cfs, the facility requirement in Peak Rate Flow Control Standard Areas is waived as described in Exception 1. The improvements within TDA 1 and TDA 2 are a transportation redevelopment project. As the total new impervious area of 3,172 square feet is less than 50% of the existing impervious surface within the project limits and the 2,567 square feet of new PGIS is less than 5,000 square feet, both TDA 1 and TDA 2 are exempt from water quality facility requirements. Onsite BMPs were analyzed to meet Core Requirement #9 by determining their application to the maximum extent feasible. Based on the guidance in section 1.2.9.3.2 of the RSWDM for Small Road Improvement and Urban Road Improvement Projects, the following BMPs were considered: • Full Dispersion: Full dispersion was determined to be infeasible for TDA 1 and TDA 2 as there is no native vegetated surface in the vicinity of the roadways for the impervious areas to disperse to. • Full Infiltration: Full infiltration was determined to be infeasible for TDA 1 and TDA 2 as soil on the site is a silt loam, which does not meet the minimum design requirements. • Limited Infiltration: Limited infiltration was determined to be infeasible for TDA 1 and TDA 2 as soil on the site is a silt loam, which does not meet the minimum design requirements. • Bioretention: Bioretention was determined to be infeasible for TDA 1 and TDA 2 as there is not available space within the project limits due to R/W and elevation constraints. TIR – Renton SW 19th Street Road Widening and SW 16th Street Roundabout 12 • Permeable Pavement: The City of Renton does not allow the use of permeable pavement on city streets. • Basic Dispersion: Basic dispersion was determined to be infeasible for TDA 1 as there is no area available for a vegetated flowpath segment due to slope and right-of-way constraints. It is infeasible for TDA 2 based on the drainage pattern and drainage infrastructure of the existing intersection that is remaining in-place. TIR – Renton SW 19th Street Road Widening and SW 16th Street Roundabout 13 5.0 Conveyance System Analysis and Design TDA 1 includes a proposed 8” PVC pipe to convey flow from a proposed inlet at an existing local low point on the west side of the intersection of SW 19th Street and Raymond Avenue to the existing storm drain main within Raymond Avenue. A rational method calculation was done for the area draining to the inlet which determined a peak flow rate of 0.19 CFS during the 100- year storm event. A Manning’s calculation was done using Hydraflow Express software which shows that the proposed pipe will have adequate capacity to convey the entirety of the peak flow rate. Results for both calculations are provided in Appendix F.

To avoid erosion and the transport of sediment offsite, the contractor will implement temporary control measures during the construction phase of the project. During construction, stormwater runoff will be conveyed in the existing conveyance systems, which are primarily storm drains. ESC measures will be needed to prevent runoff from causing erosion and discharging sediment into the existing drainage system during and after construction. Appropriate ESC measures will be needed for construction activities on existing storm drain systems. The contractor will be responsible for the phasing of erosion and sediment control measures so that they are coordinated with the staging of construction activities. Additionally, the contractor will be responsible for inspection and maintenance of temporary controls during construction, including the removal of accumulated sediment, and for the removal of the controls and remaining accumulated sediment at the end of construction. The project will follow the requirements listed in the National Pollutant Discharge Elimination System (NPDES) General Construction Stormwater Permit. Permanent measures will be implemented where needed to stabilize disturbed soils at project completion. 8.1 ESC Plan Analysis and Design (Part A) The Following ESC measures will be provided, as further detailed in the CSWPP provided in Appendix A and on the ESC plan sheets: Clearing Limits – Clearing limits will be delineated on the construction plans. Survey markings shall be places along perimeter silt fence to delineate. will be installed down slope of any fill slopes to prevent offsite sediment migration. Perimeter protection – To reduce the transport of sediment off site, the contractor will provide silt fence and straw waddles as indicated on the drawings and as needed. Sediment Retention – Catch basin filters will provide sediment retention at the locations shown on the drawings. Surface Water Control – Surface water control will be provided by using the existing and new drainage conveyance systems. No base flows are expected while the existing storm drain is replaced. However, any flows encountered should be diverted around the construction. Dust Control – If necessary, the contractor will use water per RSWDM D.2.1.8 – DUST CONTROL to prevent wind transport of soil. Exposed soils will be sprayed until wet and resprayed as needed. When using water for dust control, the contractor will spray exposed soils until they are wet, but runoff should not be generated by spraying. Oil shall not be used for dust control. TIR – Renton SW 19th Street Road Widening and SW 16th Street Roundabout 17 At the contractor’s option, a tackifier may be used with approval form the Engineer and the City of Renton. 8.2 SWPPS Plan Design (Part B) SWPP measures are detailed in the CSWPP provided in Appendix A. If soils are exposed between October 1 and March 31, the contractor will mulch and seed as much disturbed area as possible by the first week of October to provide grass cover for the wet season. The contractor will also conform to the following wet season special provisions: 1. Apply cover measures to disturbed areas that are to remain unworked for more than 2 days. 2. Protect stockpiles that are to remain unworked for more than 12 hours. 3. No area is to be left uncovered/denuded longer than 12 hours. 4. Provide onsite supplies of cover materials sufficient to cover all disturbed areas. 5. Seed all areas that are to be unworked during the wet season by the end of the first week of October. 6. Apply mulch to all seeded areas for protection. 7. Maintain a minimum of 50 linear feet of silt fence and necessary stakes at all times. 8. If the disturbed area is larger than one acre, maintain a minimum of 50 linear feet of silt fence and necessary stakes for every acre of disturbed area. 9. Provide construction road and parking lot stabilization areas for all sites, unless underlain by coarse grain soil. 10. Provide sediment retention as required. 11. Provide additional surface water controls as required. 12. Implement construction phasing and additional BMPs for construction activity near surface waters (to be evaluated by the contractor). 13. Runoff generated from dewatering activities is to be treated using suitable methods for the site. Review and maintain ESC measures on a weekly basis and within 24 hours after any runoff-producing event. 8.2.1 Maintenance Requirements All ESC measures will be inspected and maintained on a regular basis following the maintenance requirements listed for each BMP, as described in RSWDM. The contractor will TIR – Renton SW 19th Street Road Widening and SW 16th Street Roundabout 18 designate a certified CSWPP Supervisor and will give his or her name, address, and phone number to the City before construction begins. The CSWPP Supervisor will inspect the site at least once a month during the dry season, weekly during the wet season, and within 24 hours of each runoff-producing storm. If the City of Renton requires a written record of maintenance activities, a standard ESC maintenance report will be used as a written record of all maintenance. 8.2.2 Final Stabilization Before obtaining final construction approval, the following conditions must be met: All disturbed areas of the site should be vegetated or otherwise permanently stabilized. At a minimum, disturbed areas will be seeded and mulched to provide a high likelihood that sufficient cover will develop shortly after final approval. If seeded during the dry season, the seeded area will be irrigated as necessary to maintain the sprouted vegetation until the start of the wet season. Structural measures such as silt fences, pipe slope drains, construction entrances, and storm drain inlet protection will be removed. All permanent surface water facilities including catch basins, manholes, pipes, ditches, and channels will be cleaned. 8.2.4 Roads and Utilities Due to the linear nature of the project and limited right-of-way along the project, the contractor may propose other measures to better fit project conditions and provide reasonable protection. These measures may include alternative and experimental measures.

It includes the construction of a compact roundabout within the limits of the existing intersection at 16th Street and Raymond Avenue and the widening of a section of 19th Street to the east of (and including) the intersection with Raymond Avenue. Improvements may include, but are not limited to, installation of AC pavement, installation of sidewalk/pedestrian ramps, installation of minor storm drain pipe/catch basins and installation of curb and gutter. VICINITY MAP CSWPP – Renton SW 19th Street Road Widening and SW 18th Street Roundabout 2 2.0 Erosion and Sediment Control Measures This section details the ESC measures that are required to minimize erosion and sediment transport off a construction site and protect areas of existing and proposed stormwater facilities (flow control facilities, runoff treatment facilities, and on-site BMPs). These ESC measures represent Best Management Practices (BMPs) for the control of erosion and entrained sediment as well as other impacts related to construction such as increased runoff due to land disturbing activities. To comply with the City of Renton’s ESC Standards, the following categories of ESC measures have been considered for application to the project site, summarized as follows and described below. ECS plans are provided in Appendix A 1. Clearing Limits: Prior to any site clearing or grading, areas to remain undisturbed during project construction shall be delineated on the project’s ESC plan and physically marked on the project site. • Clearing limits will be delineated on the construction plans. Survey markings shall be places along perimeter silt fence to delineate. See additional detail below 2. Cover Measures: Temporary and permanent cover measures shall be provided when necessary to protect disturbed areas. The intent of these measures is to prevent erosion by having as much area as possible covered during any period of precipitation. • Exposed areas will be seeded and mulched to achieve final stabilization 3. Perimeter Protection: Perimeter protection to filter sediment from sheet flow shall be provided downstream of all disturbed areas prior to upslope grading. • To reduce the transport of sediment off site, the contractor will provide silt fence and straw waddles as indicated on the drawings and as needed. 4. Traffic Area Stabilization: Unsurfaced entrances, roads, and parking areas used by construction traffic shall be stabilized to minimize erosion and tracking of sediment offsite. • Traffic area stabilization is not proposed due to the limited exposed soil associated with small scale of grading and subsequent roadway stabilization. 5. Sediment Retention: Surface water collected from all disturbed areas of the site shall be routed through a sediment pond or trap prior to release from the site, except those areas at the perimeter of the site small enough to be treated solely with perimeter protection. Sediment retention facilities shall be installed prior to grading any contributing area. CSWPP – Renton SW 19th Street Road Widening and SW 18th Street Roundabout 3 • Catch basin filters will provide sediment retention at the locations shown on the drawings. 6. Surface Water Collection: Surface water collection measures (e.g., ditches, berms, etc.) shall be installed to intercept all surface water from disturbed areas, convey it to a sediment pond or trap, and discharge it downstream of any disturbed areas. Areas at the perimeter of the site, which are small enough to be treated solely with perimeter protection, do not require surface water collection. Significant sources of upstream surface water that drain onto disturbed areas shall be intercepted and conveyed to a stabilized discharge point downstream of the disturbed areas. Surface water collection measures shall be installed concurrently with or immediately following rough grading and shall be designed, constructed, and stabilized as needed to minimize erosion. • Surface water control will be provided by using the existing and new drainage conveyance systems. No base flows are expected while the existing storm drain is replaced. However, any flows encountered should be diverted around the construction. 7. Dewatering Control: The water resulting from construction site de-watering activities must be treated prior to discharge or disposed of as specified. • Measures will applied if dewatering is required 8. Dust Control: Preventative measures to minimize wind transport of soil shall be implemented when a traffic hazard may be created or when sediment transported by wind is likely to be deposited in water resources. • If necessary, the contractor will use water per RSWDM D.2.1.8 – DUST CONTROL to prevent wind transport of soil. Exposed soils will be sprayed until wet and resprayed as needed. When using water for dust control, the contractor will spray exposed soils until they are wet, but runoff should not be generated by spraying. Oil shall not be used for dust control. At the contractor’s option, a tackifier may be used with approval form the Engineer and the City of Renton. 9. Flow Control: Surface water from disturbed areas must be routed through the project’s onsite flow control facility or other provisions must be made to prevent increases in the existing site conditions 2-year and 10-year runoff peaks discharging from the project site during construction (flow control facility, runoff treatment facility, and on-site BMP areas [existing or proposed] shall not be used for this purpose). • Project is excempt from flow-control requirements 10. Control Pollutants: Stormwater pollution prevention (SWPPS) measures are required to prevent, reduce, or eliminate the discharge of pollutants to onsite or adjacent stormwater systems or watercourses from construction-related activities such as materials delivery and storage, onsite equipment fueling and maintenance, demolition of existing buildings and disposition of demolition materials and other waste, and CSWPP – Renton SW 19th Street Road Widening and SW 18th Street Roundabout 4 concrete handling, washout and disposal. Section D.2.2 describes BMPs specific to this purpose; additionally, several of the ESC BMPs described herein are applicable. • Pollutants will be controlled as described in section 3 of CSWPP 11. Protect Existing and Proposed Stormwater Facilities and On-site BMPs: Sedimentation and soil compaction reduce the infiltration capacity of native and engineered soils. Protection measures shall be applied/installed and maintained so as to prevent adverse impacts to existing stormwater facilities and on-site BMPs and areas of proposed stormwater facilities and on-site BMPs for the project. Adverse impacts can prompt the requirement to restore or replace affected stormwater facilities and on-site BMPs. • Stormwater facilities will be protected from sedimentation through installation of erosion and sediment control BMPs. 12. Maintain Protective BMPs: Protection measures shall be maintained to ensure continued performance of their intended function, to prevent adverse impacts to existing BMPs/facilities and areas of proposed BMPs/facilities, and protect other disturbed areas of the project. • Erosion and sediment control BMPs will be maintained and repaired as needed to ensure continued performance of their intended function. 13. Manage the Project: Coordination and timing of site development activities relative to ESC concerns, and timely inspection, maintenance and update of protective measures are necessary to effectively manage the project and ensure the success of protective ESC and SWPPS design and implementation • CSWPP Supervisor will be assigned to manage erosion and sediment on the project. CSWPP – Renton SW 19th Street Road Widening and SW 18th Street Roundabout 5 CLEARING LIMITS Prior to any site clearing or grading, those areas that are to remain undisturbed during project construction shall be delineated. At a minimum, clearing limits shall be installed at the edges of all critical area buffers and any other areas required to be left uncleared such as portions of the site subject to clearing limits under RMC 4-4-060, areas around significant trees identified to be retained, on-site BMP areas to be protected, and other areas identified to be left undisturbed to protect sensitive features. Purpose: The purpose of clearing limits is to prevent disturbance of those areas of the project site that are not designated for clearing or grading. This is important because limiting site disturbance is the single most effective method for reducing erosion. Clearing limits may also be used to control construction traffic, thus reducing the disturbance of soil and limiting the amount of sediment tracked off site. When to Install: Clearing limits shall be installed prior to the clearing and/or grading of the site. Measures to Use: Marking clearing limits by delineating the site with a continuous length of brightly colored survey tape is sometimes sufficient. The tape may be supported by vegetation or stakes, and it shall be 3 to 6 feet high and highly visible. Critical areas and their buffers require more substantial protection and shall be delineated with plastic or metal safety fences or stake and wire fences. Fencing may be required at the City’s discretion to control construction traffic or at any location where greater protection is warranted. Permanent fencing may also be used if desired by the applicant. Silt fence, in combination with survey flagging, is also an acceptable method of marking critical areas and their buffers. CSWPP – Renton SW 19th Street Road Widening and SW 18th Street Roundabout 6 TEMPORARY AND PERMANENT SEEDING Purpose Seeding is intended to reduce erosion by stabilizing exposed soils. A well-established vegetative cover is one of the most effective methods of reducing erosion. Conditions of Use 1. Seeding shall be used throughout the project on disturbed areas that have reached final grade or that will remain unworked for more than 30 days. 2. Vegetation-lined channels shall be seeded. Channels that will be vegetated should be installed before major earthwork and hydroseeded or covered with a Bonded Fiber Matrix (BFM). 3. Retention/detention ponds shall be seeded as required. 4. At the City’s discretion, seeding without mulch during the dry season is allowed even though it will take more than seven days to develop an effective cover. Mulch is, however, recommended at all times because it protects seeds from heat, moisture loss, and transport due to runoff. 5. Prior to the beginning of the wet season, all disturbed areas shall be reviewed to identify which ones can be seeded in preparation for the winter rains (see Section D.2.4.2). Disturbed areas shall be seeded within one week of the beginning of the wet season. A sketch map of those areas to be seeded and those areas to remain uncovered shall be submitted to the CED inspector. The CED inspector may require seeding of additional areas in order to protect surface waters, adjacent properties, or drainage facilities. 6. At final site stabilization, all disturbed areas not otherwise vegetated or stabilized shall be seeded and mulched (see Section D.2.4.5). Design and Installation Specifications 1. The best time to seed is fall (late September to October) or in spring (mid-March to June). Irrigation is required during the first summer following installation if seeding occurs in spring or summer or during prolonged dry times of year. Areas may also be seeded during the winter months, but it may take additional spring seeding applications to develop a dense groundcover due to cold temperatures. The application and maintenance of mulch is critical for winter seeding. 2. To prevent seed from being washed away, confirm that all required surface water control measures have been installed. 3. The seedbed should not be compacted because soils that are well compacted will not vegetate as quickly or thoroughly. Slopes steeper than 3H:1V shall be surface roughened. Roughening can be accomplished in a variety of ways, but the typical CSWPP – Renton SW 19th Street Road Widening and SW 18th Street Roundabout 7 method is track walking, or driving a crawling tractor up and down the slope, leaving cleat imprints parallel to the slope contours. 4. In general, 10-20-20 N-P-K (nitrogen-phosphorus-potassium) fertilizer may be used at a rate of 90 pounds per acre. Slow-release fertilizers are preferred because they are more efficient and have fewer environmental impacts. It is recommended that areas being seeded for final landscaping conduct soil tests to determine the exact type and quantity of fertilizer needed. This will prevent the over-application of fertilizer. Disturbed areas within 200 feet of water bodies and wetlands must use slow-release low-phosphorus fertilizer (typical proportions 3-1-2 N-P-K). 5. The following requirements apply to mulching: a. Mulch is always required for seeding slopes greater than 3H:1V (see Section D.2.1.2.2). b. If seeding during the wet season, mulch is required. c. The use of mulch may be required during the dry season at the City’s discretion if grass growth is expected to be slow, the soils are highly erodible due to soil type or gradient, there is a water body close to the disturbed area, or significant precipitation (see Section D.2.4.2) is anticipated before the grass will provide effective cover. d. Mulch may be applied on top of the seed or simultaneously by hydroseeding. 6. Hydroseeding is allowed as long as tackifier is included. Hydroseeding with wood fiber mulch is adequate during the dry season. Application of hydroseeded wood fiber mulch should be appropriate for slope angle. Follow manufacturer specifications for application rates. 7. Areas to be permanently landscaped shall use soil amendments. Good quality topsoil shall be tilled into the top six inches to reduce the need for fertilizer and improve the overall soil quality. Most native soils will require the addition of four inches of well- rotted compost to be tilled into the soil to provide a good quality topsoil. Compost used should meet specifications provided in Reference Section 11-C of the SWDM. 8. The seed mixes listed below include recommended mixes for both temporary and permanent seeding. These mixes, with the exception of the wetland mix, shall be applied at a rate of 80 to 100 seeds per square foot. Wet sites should apply 120 to 150 seeds per square foot. Local suppliers should be consulted for information on current Pure Live Seed (PLS) rates and species specific seeds per pound in order to determine seed mix PLS pounds of seed per acre. The appropriate mix depends on a variety of factors, including exposure, soil type, slope, and expected foot traffic. Alternative seed mixes approved by the City may be used. Table D.2.1.2.B presents the standard mix for those areas where temporary or permanent vegetative cover is required. The following mix assumes a desired 150 seeds per square foot and should be applied at approximately 37 pounds of pure live seed per acre. CSWPP – Renton SW 19th Street Road Widening and SW 18th Street Roundabout 8 CSWPP – Renton SW 19th Street Road Widening and SW 18th Street Roundabout 9 PERIMETER PROTECTION - SILT FENCE Purpose Use of a silt fence reduces the transport of coarse sediment from a construction site by providing a temporary physical barrier to sediment and reducing the runoff velocities of overland flow. Conditions of Use 1. Silt fence may be used downslope of all disturbed areas. 2. Silt fence is not intended to treat concentrated flows, nor is it intended to treat substantial amounts of overland flow. Any concentrated flows must be conveyed through the drainage system to a sediment trap or pond. The only circumstance in which overland flow may be treated solely by a silt fence, rather than by a sediment trap or pond, is when the area draining to the fence is small (see “Criteria for Use as Primary Treatment” in Section D.2.1.3 above). Design and Installation Specifications 1. See Figure D.2.1.3.A and Figure D.2.1.3.B for details. 2. The geotextile used must meet the standards listed below. A copy of the manufacturer’s fabric specifications must be available on site. AOS (ASTM D4751) 30–100 sieve size (0.60–0.15 mm) for slit film 50–100 sieve size (0.30–0.15 mm) for other fabrics Water Permittivity (ASTM D4491) 0.02 sec-1 minimum Grab Tensile Strength (ASTM D4632) (see Specification Note 3) 180 lbs. min. for extra strength fabric 100 lbs. min. for standard strength fabric Grab Tensile Elongation (ASTM D4632) 30% max. (woven) Ultraviolet Resistance (ASTM D4355) 70% min. 3. Standard strength fabric requires wire backing to increase the strength of the fence. Wire backing or closer post spacing may be required for extra strength fabric if field performance warrants a stronger fence. 4. Where the fence is installed, the slope shall be no steeper than 2H:1V. 5. If a typical silt fence (per Figure D.2.1.3.A) is used, the standard 4 x 4 trench may be reduced as long as the bottom 8 inches of the silt fence fabric is well buried and secured in a trench that stabilizes the fence and does not allow water to bypass or undermine the silt fence. Maintenance Standards 1. Any damage shall be repaired immediately. CSWPP – Renton SW 19th Street Road Widening and SW 18th Street Roundabout 10 2. If concentrated flows are evident uphill of the fence, they must be intercepted and conveyed to a sediment trap or pond. 3. It is important to check the uphill side of the fence for signs of the fence clogging and acting as a barrier to flow and then causing channelization of flows parallel to the fence. If this occurs, replace the fence or remove the trapped sediment. 4. Sediment must be removed when the sediment is 6 inches high. 5. If the filter fabric (geotextile) has deteriorated due to ultraviolet breakdown, it shall be replaced. CSWPP – Renton SW 19th Street Road Widening and SW 18th Street Roundabout 11 PERIMETER PROTECTION - STRAW WATTLES Purpose Wattles are erosion and sediment control barriers consisting of straw wrapped in biodegradable tubular plastic or similar encasing material. Wattles may reduce the velocity and can spread the flow of rill and sheet runoff, and can capture and retain sediment. Straw wattles are typically 8 to 10 inches in diameter and 25 to 30 feet in length. The wattles are placed in shallow trenches and staked along the contour of disturbed or newly constructed slopes. Conditions of Use 1. Install on disturbed areas that require immediate erosion protection. 2. Use on slopes requiring stabilization until permanent vegetation can be established. 3. Can be used along the perimeter of a project, as a check dam in unlined ditches and around temporary stockpiles 4. Wattles can be staked to the ground using willow cuttings for added revegetation. 5. Rilling can occur beneath and between wattles if not properly entrenched, allowing water to pass below and between wattles Design and Installation Specifications 1. It is critical that wattles are installed perpendicular to the flow direction and parallel to the slope contour. 2. Narrow trenches should be dug across the slope, on contour, to a depth of 3 to 5 inches on clay soils and soils with gradual slopes. On loose soils, steep slopes, and during high rainfall events, the trenches should be dug to a depth of 5 to 7 inches, or ½ to 2/3 of the thickness of the wattle. 3. Start construction of trenches and installing wattles from the base of the slope and work uphill. Excavated material should be spread evenly along the uphill slope and compacted using hand tamping or other method. Construct trenches at contour intervals of 3 to 30 feet apart depending on the steepness of the slope, soil type, and rainfall. The steeper the slope the closer together the trenches should be constructed. Vertical distance between wattles is not to exceed 10 feet. 4. Install the wattles snugly into the trenches and abut tightly end to end. Do not overlap the ends. 5. Install stakes at each end of the wattle, and at 4 foot centers along the entire length of the wattle. 6. If required, install pilot holes for the stakes using a straight bar to drive holes through the wattle and into the soil. 7. At a minimum, wooden stakes should be approximately ¾ x ¾ x 24 inches. Willow cuttings or 3/8 inch rebar can also be used for stakes. CSWPP – Renton SW 19th Street Road Widening and SW 18th Street Roundabout 12 8. Stakes should be driven through the middle of the wattle, leaving 2 to 3 inches of the stake protruding above the wattle. Maintenance Standards 1. Inspect wattles prior to forecasted rain, daily during extended rain events, after rain events, weekly during the wet season, and at two week intervals at all other times of the year. 2. Repair or replace split, torn, raveling, or slumping wattles 3. Remove sediment accumulations when exceeding ½ the height between the top of the wattle and the ground surface CSWPP – Renton SW 19th Street Road Widening and SW 18th Street Roundabout 13 SEDIMENT RETENTION - STORM DRAIN INLET PROTECTION Purpose Storm drain inlets are protected to prevent coarse sediment from entering storm drainage systems. Temporary devices around storm drains assist in improving the quality of water discharged to inlets or catch basins by ponding sediment-laden water. These devices are effective only for relatively small drainage areas. Conditions of Use 1. Protection shall be provided for all storm drain inlets downslope and within 500 feet of a disturbed or construction area, unless the runoff that enters the catch basin will be conveyed to a sediment pond or trap. 2. Inlet protection may be used anywhere at the applicant’s discretion to protect the drainage system. This will, however, require more maintenance, and it is highly likely that the drainage system will still require some cleaning. 3. The contributing drainage area must not be larger than one acre. Design and Installation Specifications 1. There are many options for protecting storm drain inlets. Two commonly used options are filter fabric protection and catch basin inserts. Filter fabric protection (see Figure D.2.1.5.E) is filter fabric (geotextile) placed over the grate. This method is generally very ineffective and requires intense maintenance efforts. Therefore, filter fabric protection is not allowed in the City of Renton. Catch basin inserts (see Figure D.2.1.5.F) are manufactured devices that nest inside a catch basin. This method also requires a high frequency of maintenance to be effective. Trapping sediment in the catch basins is unlikely to improve the water quality of runoff if it is treated in a pond or trap because the coarse particles that are trapped at the catch basin settle out very quickly in the pond or trap. Catch basin protection normally only improves water quality where there is no treatment facility downstream. In these circumstances, catch basin protection is an important last line of defense. It is not, however, a substitute for preventing erosion. 2. It is sometimes possible to construct a small sump around the catch basin before final surfacing of the road. This is allowed because it can be a very effective method of sediment control. 3. Block and gravel filters, gravel and wire mesh filter barriers, and bag barriers filled with various filtering media placed around catch basins can be effective when the drainage area is 1 acre or less and flows do not exceed 0.5 cfs. It is necessary to allow for overtopping to prevent flooding. Many manufacturers have various inlet protection filters that are very effective in keeping sediment-laden water from entering the storm drainage system. The following are examples of a few common methods. CSWPP – Renton SW 19th Street Road Widening and SW 18th Street Roundabout 14 a) Block and gravel filters (Figure D.2.1.5.G) are a barrier formed around an inlet with standard concrete block and gravel, installed as follows: • Height is 1 to 2 feet above the inlet. • Recess the first row of blocks 2 inches into the ground for stability. • Support subsequent rows by placing a 2x4 through the concrete block opening. • Do not use mortar. • Lay some blocks in the bottom row on their side for dewatering the pooled water. • Place cloth or mesh with ½ inch openings over all block openings. • Place gravel below the top of blocks on slopes of 2:1 or flatter. • An alternate design is a gravel donut. b) Gravel and wire mesh filters consist of a gravel barrier placed over the top of an inlet. This structure generally does not provide overflow. Install as follows: • Cloth or comparable wire mesh with ½ inch openings is placed over inlet. Coarse aggregate covers the cloth or mesh. • Height/depth of gravel should be 1 foot or more, 18 inches wider than inlet on all sides. c) Curb inlet protection with a wooden weir is a barrier formed around an inlet with a wooden frame and gravel, installed as follows: • Construct a frame and attach wire mesh (½ inch openings) and filter fabric to the frame. • Pile coarse washed aggregate against the wire/fabric. • Place weight on frame anchors. d) Curb and gutter sediment barriers (Figure D.2.1.5.H) consist of sandbags or rock berms (riprap and aggregate) 3 feet high and 3 feet wide in a horseshoe shape, installed as follows: • Bags of either burlap or woven geotextile fabric, filled with a variety of media such as gravel, wood chips, compost or sand stacked tightly allows water to pond and allows sediment to separate from runoff. • Leave a “one bag gap” in the top row of the barrier to provide a spillway for overflow. • Construct a horseshoe shaped berm, faced with coarse aggregate if using riprap, 3 x 3 and at least 2 feet from the inlet. • Construct a horseshoe shaped sedimentation trap on the outside of the berm to sediment trap standards for protecting a culvert inlet 4. Excavated drop inlet sediment traps are appropriate where relatively heavy flows are expected and overflow capability is needed. If emergency overflow is provided, additional end-of-pipe treatment may be required. Excavated drop inlets consist of an CSWPP – Renton SW 19th Street Road Widening and SW 18th Street Roundabout 15 excavated impoundment area around a storm drain. Sediment settles out of the stormwater prior to enter the drain. Install according to the following specifications: a) The impoundment area should have a depth of 1 to 2 feet measured from the crest of the inlet structure. b) Side slopes of the excavated area must be no steeper than 2:1. c) Minimum volume of the excavated area should be 35 cubic yards. d) Install provisions for draining the area to prevent standing water problems. e) Keep the area clear of debris. f) Weep holes may be drilled into the side of the inlet. g) Protect weep holes with wire mesh and washed aggregate. h) Weep holes must be sealed when removing and stabilizing excavated area. i) A temporary dike may be necessary on the down slope side of the structure to prevent bypass flow. Maintenance Standards 1. Any accumulated sediment on or around inlet protection shall be removed immediately. Sediment shall not be removed with water, and all sediment must be disposed of as fill on site or hauled off site. 2. Any sediment in the catch basin insert shall be removed when the sediment has filled one-third of the available storage. The filter media for the insert shall be cleaned or replaced at least monthly. 3. Regular maintenance is critical for all forms of catch basin/inlet protection. Unlike many forms of protection that fail gradually, catch basin protection will fail suddenly and completely if not maintained properly. CSWPP – Renton SW 19th Street Road Widening and SW 18th Street Roundabout 16 DUST CONTROL Preventative measures to minimize the wind transport of soil shall be taken when a traffic hazard may be created or when sediment transported by wind is likely to be deposited in water resources or adjacent properties. Purpose To prevent wind transport of dust from exposed soil surfaces onto roadways, drainage ways, and surface waters. When to Install Dust control shall be implemented when exposed soils are dry to the point that wind transport is possible and roadways, drainage ways, or surface waters are likely to be impacted. Dust control measures may consist of chemical, structural, or mechanical methods. Measures to Install Water is the most common dust control (or palliative) used in the area. When using water for dust control, the exposed soils shall be sprayed until wet, but runoff shall not be generated by spraying. CSWPP – Renton SW 19th Street Road Widening and SW 18th Street Roundabout 17 3.0 Storm Water Pollution Prevention This section details the SWPPS measures that are required to prevent, reduce, or eliminate the discharge of pollutants to onsite or adjacent stormwater systems or watercourses from construction-related activities such as materials delivery and storage, onsite equipment fueling and maintenance, demolition of existing buildings and disposition of demolition materials and other waste, and concrete handling, washout and disposal. These SWPPS measures represent Best Management Practices (BMPs) for the control of pollutant drips and spills as well as other impacts related to construction such as increased pH in concrete construction and handling activities. Compliance with each of the SWPPS measures, and with any project-specific control measures, to the extent applicable and necessary to meet the performance criteria in Section D.2.2, and compliance with the CSWPP implementation requirements in Section D.2.4, constitutes overall compliance with the City’s CSWPP Standards. The standards for each individual SWPPS measure are divided into four sections: 1. Purpose 2. Conditions of Use 3. Design and Installation Specifications 4. Maintenance Requirements. Note that the “Conditions of Use” always refers to site conditions. As site conditions change, SWPPS measures must be changed to remain in compliance with the requirements of the Renton Surface Water Design Manual. To be in compliance with City SWPPS Standards, the following SWPPS measures have been considered for application to the project site as detailed in the following sections. The construction pollutant generating concerns addressed by the BMPs that follow include: • Concrete handling, washout and disposal (specifically portland cement concrete) • Sawcutting and surfacing activities • Materials delivery, storage and containment • Filtration and chemical treatment of construction water to facilitate disposal or discharge to approved locations. • Reporting requirements and documentation availability for specific BMP processes. CSWPP – Renton SW 19th Street Road Widening and SW 18th Street Roundabout 18 CONCRETE HANDLING Purpose Concrete work can generate process water and slurry that contain fine particles and high pH, both of which can violate water quality standards in the receiving water. Concrete spillage or concrete discharge to surface waters of the State is prohibited. Use this BMP to minimize and eliminate concrete, concrete process water, and concrete slurry from entering waters of the state. Conditions of Use Any time concrete is used, utilize these management practices. Concrete construction projects include, but are not limited to, curbs, sidewalks, roads, bridges, foundations, floors, stormwater vaults, retaining walls, driveways and runways. Design and Installation Specifications 1. Ensure that washout of concrete trucks, chutes, pumps, and internals is performed at an approved off-site location or in designated concrete washout areas. Do not wash out concrete trucks, chutes, pumps, or internals onto the ground, or into storm drains, open ditches, streets, or streams. Refer to BMP D.2.2.2 for information on concrete washout areas. 2. Return unused concrete remaining in the truck and pump to the originating batch plant for recycling. Do not dump excess concrete on site, except in designated concrete washout areas. 3. Wash off hand tools including, but not limited to, screeds, shovels, rakes, floats, and trowels into formed areas awaiting future concrete pours only. 4. Do not wash out to formed areas awaiting infiltration BMPs. 5. Wash equipment difficult to move, such as concrete pavers in areas that do not directly drain to natural or constructed stormwater conveyances. 6. Do not allow washdown from areas, such as concrete aggregate driveways, to drain directly to natural or constructed stormwater conveyances. 7. Contain washwater and leftover product in a lined container when no formed areas are available. Dispose of contained concrete in a manner that does not violate ground water or surface water quality standards. 8. Always use forms or solid barriers for concrete pours, such as pilings, within 15-feet of surface waters. 9. Refer to BMPs D.2.2.7 and D.2.2.8 for pH adjustment requirements. 10. Refer to the Construction Stormwater General Permit for pH monitoring requirements if the project involves one of the following activities: • Significant concrete work (greater than 1,000 cubic yards poured concrete or recycled concrete used over the life of a project). CSWPP – Renton SW 19th Street Road Widening and SW 18th Street Roundabout 19 • The use of engineered soils amended with (but not limited to) Portland cement- treated base, cement kiln dust or fly ash. • Discharging stormwater to segments of water bodies on the 303(d) list (Category 5) for high pH. Maintenance Standards Check containers for holes in the liner daily during concrete pours and repair the same day. CSWPP – Renton SW 19th Street Road Widening and SW 18th Street Roundabout 20 CONCRETE WASHOUT AREA Purpose Prevent or reduce the discharge of pollutants to stormwater from concrete waste by conducting washout off-site, or performing onsite washout in a designated area to prevent pollutants from entering surface waters or ground water. Conditions of Use Concrete washout area best management practices are implemented on construction projects where: • Concrete is used as a construction material • It is not possible to dispose of all concrete wastewater and washout off-site (ready mix plant, etc.). • Concrete trucks, pumpers, or other concrete coated equipment are washed onsite. Note: If less than 10 concrete trucks or pumpers need to be washed out onsite, the washwater may be disposed of in a formed area awaiting concrete or an upland disposal site where it will not contaminate surface or ground water. The upland disposal site shall be at least 50 feet from sensitive areas such as storm drains, open ditches, or water bodies, including wetlands. Design and Installation Specifications Implementation The following steps will help reduce stormwater pollution from concrete wastes: 1. Perform washout of concrete trucks at an approved off-site location or in designated concrete washout areas only. 2. Do not wash out concrete trucks onto the ground, or into storm drains, open ditches, streets, or streams. 3. Do not allow excess concrete to be dumped onsite, except in designated concrete washout areas. 4. Concrete washout areas may be prefabricated concrete washout containers, or self- installed structures (above-grade or below-grade). 5. Prefabricated containers are most resistant to damage and protect against spills and leaks. Companies may offer delivery service and provide regular maintenance and disposal of solid and liquid waste. 6. If self-installed concrete washout areas are used, below-grade structures are preferred over above-grade structures because they are less prone to spills and leaks. 7. Self-installed above-grade structures should only be used if excavation is not practical. Education 1. Discuss the concrete management techniques described in this BMP with the ready-mix concrete supplier before any deliveries are made. 2. Educate employees and subcontractors on the concrete waste management techniques described in this BMP. CSWPP – Renton SW 19th Street Road Widening and SW 18th Street Roundabout 21 3. Arrange for contractor’s superintendent or Certified Erosion and Sediment Control Lead (CESCL) to oversee and enforce concrete waste management procedures. 4. A sign should be installed adjacent to each temporary concrete washout facility to inform concrete equipment operators to utilize the proper facilities. Contracts Incorporate requirements for concrete waste management into concrete supplier and subcontractor agreements. Location and Placement 1. Locate washout area at least 50 feet from sensitive areas such as storm drains, open ditches, or water bodies, including wetlands. 2. Allow convenient access for concrete trucks, preferably near the area where the concrete is being poured. 3. If trucks need to leave a paved area to access washout, prevent track-out with a pad of rock or quarry spalls (see BMP D.2.1.4.2). These areas should be far enough away from other construction traffic to reduce the likelihood of accidental damage and spills. 4. The number of facilities you install should depend on the expected demand for storage capacity. 5. On large sites with extensive concrete work, washouts should be placed in multiple locations for ease of use by concrete truck drivers. On-Site Temporary Concrete Washout Facility, Transit Truck Washout Procedures: 1. Temporary concrete washout facilities shall be located a minimum of 50 feet from sensitive areas including storm drain inlets, open drainage facilities, and watercourses. (See Figures D.2.2.2.A, D.2.2.2.B, and D.2.2.2.C). 2. Concrete washout facilities shall be constructed and maintained in sufficient quantity and size to contain all liquid and concrete waste generated by washout operations. 3. Washout of concrete trucks shall be performed in designated areas only. 4. Concrete washout from concrete pumper bins can be washed into concrete pumper trucks and discharged into designated washout area or properly disposed of off-site. 5. Once concrete wastes are washed into the designated area and allowed to harden, the concrete should be broken up, removed, and disposed of per applicable solid waste regulations. Dispose of hardened concrete on a regular basis. 6. Temporary Above-Grade Concrete Washout Facility a. Temporary concrete washout facility (type above grade) should be constructed as shown on the details below, with a recommended minimum length and minimum width of 10 ft, but with sufficient quantity and volume to contain all liquid and concrete waste generated by washout operations. b. Plastic lining material should be a minimum of 10 mil polyethylene sheeting and should be free of holes, tears, or other defects that compromise the impermeability of the material. CSWPP – Renton SW 19th Street Road Widening and SW 18th Street Roundabout 22 7. Temporary Below-Grade Concrete Washout Facility a. Temporary concrete washout facilities (type below grade) should be constructed as shown on the details below, with a recommended minimum length and minimum width of 10 ft. The quantity and volume should be sufficient to contain all liquid and concrete waste generated by washout operations. b. Lath and flagging should be commercial type. c. Plastic lining material shall be a minimum of 10 mil polyethylene sheeting and should be free of holes, tears, or other defects that compromise the impermeability of the material. d. Liner seams shall be installed in accordance with manufacturers’ recommendations. e. Soil base shall be prepared free of rocks or other debris that may cause tears or holes in the plastic lining material. Maintenance Standards Inspection and Maintenance 1. Inspect and verify that concrete washout BMPs are in place prior to the commencement of concrete work. 2. During periods of concrete work, inspect daily to verify continued performance. a. Check overall condition and performance. b. Check remaining capacity (% full). c. If using self-installed washout facilities, verify plastic liners are intact and sidewalls are not damaged. d. If using prefabricated containers, check for leaks. 3. Washout facilities shall be maintained to provide adequate holding capacity with a minimum freeboard of 12 inches. 4. Washout facilities must be cleaned, or new facilities must be constructed and ready for use once the washout is 75% full. 5. If the washout is nearing capacity, vacuum and dispose of the waste material in an approved manner. a. Do not discharge liquid or slurry to waterways, storm drains or directly onto ground. b. Do not use sanitary sewer without local approval. c. Place a secure, non-collapsing, non-water collecting cover over the concrete washout facility prior to predicted wet weather to prevent accumulation and overflow of precipitation. d. Remove and dispose of hardened concrete and return the structure to a functional condition. Concrete may be reused onsite or hauled away for disposal or recycling. CSWPP – Renton SW 19th Street Road Widening and SW 18th Street Roundabout 23 6. When you remove materials from the self-installed concrete washout, build a new structure; or, if the previous structure is still intact, inspect for signs of weakening or damage, and make any necessary repairs. Re-line the structure with new plastic after each cleaning. Removal of Temporary Concrete Washout Facilities 1. When temporary concrete washout facilities are no longer required for the work, the hardened concrete, slurries and liquids shall be removed and properly disposed of. 2. Materials used to construct temporary concrete washout facilities shall be removed from the site of the work and disposed of or recycled. 3. Holes, depressions or other ground disturbance caused by the removal of the temporary concrete washout facilities shall be backfilled, repaired, and stabilized to prevent erosion.

Concrete spillage or concrete discharge to surface waters of the State is prohibited. Use this BMP to minimize and eliminate process water and slurry created through sawcutting or surfacing from entering waters of the State. Conditions of Use Utilize these management practices anytime sawcutting or surfacing operations take place. Sawcutting and surfacing operations include, but are not limited to, sawing, coring, grinding, roughening, hydro-demolition, bridge and road surfacing Design and Installation Specifications 1. Vacuum slurry and cuttings during cutting and surfacing operations. 2. Slurry and cuttings shall not remain on permanent concrete or asphalt pavement overnight. 3. Slurry and cuttings shall not drain to any natural or constructed drainage conveyance including stormwater systems. This may require temporarily blocking catch basins. 4. Dispose of collected slurry and cuttings in a manner that does not violate ground water or surface water quality standards. 5. Do not allow process water generated during hydro-demolition, surface roughening or similar operations to drain to any natural or constructed drainage conveyance including stormwater systems. Dispose process water in a manner that does not violate ground water or surface water quality standards. 6. Handle and dispose cleaning waste material and demolition debris in a manner that does not cause contamination of water. Dispose of sweeping material from a pick-up sweeper at an appropriate disposal site. Maintenance Standards Continually monitor operations to determine whether slurry, cuttings, or process water could enter waters of the state. If inspections show that a violation of water quality standards could occur, stop operations and immediately implement preventive measures such as berms, barriers, secondary containment, and vacuum trucks. MATERIAL DELIVERY, STORAGE, AND CONTAINMENT Purpose Prevent, reduce, or eliminate the discharge of pollutants to the stormwater system or watercourses from material delivery and storage. Minimize the storage of hazardous materials onsite, store materials in a designated area, and install secondary containment. CSWPP – Renton SW 19th Street Road Widening and SW 18th Street Roundabout 27 Conditions of Use These procedures are suitable for use at all construction sites with delivery and storage of the following materials: • Petroleum products such as fuel, oil and grease • Soil stabilizers and binders (e.g., Polyacrylamide) • Fertilizers, pesticides and herbicides • Detergents • Asphalt and concrete compounds • Hazardous chemicals such as acids, lime, adhesives, paints, solvents and curing compounds • Any other material that may be detrimental if released to the environment Design and Installation Specifications The following steps should be taken to minimize risk: 1. Temporary storage area should be located away from vehicular traffic, near the construction entrance(s), and away from waterways or storm drains. 2. Material Safety Data Sheets (MSDS) should be supplied for all materials stored. Chemicals should be kept in their original labeled containers. 3. Hazardous material storage onsite should be minimized. 4. Hazardous materials should be handled as infrequently as possible. 5. During the wet weather season (October 1 – April 30), consider storing materials in a covered area. 6. Materials should be stored in secondary containments, such as earthen dike, horse trough, or even a children’s wading pool for non-reactive materials such as detergents, oil, grease, and paints. Small amounts of material may be secondarily contained in “bus boy” trays or concrete mixing trays. 7. Do not store chemicals, drums, or bagged materials directly on the ground. Place these items on a pallet and, when possible, and within secondary containment. 8. If drums must be kept uncovered, store them at a slight angle to reduce ponding of rainwater on the lids to reduce corrosion. Domed plastic covers are inexpensive and snap to the top of drums, preventing water from collecting. Material Storage Areas and Secondary Containment Practices: 1. Liquids, petroleum products, and substances listed in 40 CFR Parts 110, 117, or 302 shall be stored in approved containers and drums and shall not be overfilled. Containers and drums shall be stored in temporary secondary containment facilities. 2. Temporary secondary containment facilities shall provide for a spill containment volume able to contain 10% of the total enclosed container volume of all containers, or 110% of the capacity of the largest container within its boundary, whichever is greater. 3. Secondary containment facilities shall be impervious to the materials stored therein for a minimum contact time of 72 hours. CSWPP – Renton SW 19th Street Road Widening and SW 18th Street Roundabout 28 4. Secondary containment facilities shall be maintained free of accumulated rainwater and spills. In the event of spills or leaks, accumulated rainwater and spills shall be collected and placed into drums. These liquids shall be handled as hazardous waste unless testing determines them to be non-hazardous. 5. Sufficient separation should be provided between stored containers to allow for spill cleanup and emergency response access. 6. During the wet weather season (October 1 – April 30), each secondary containment facility shall be covered during non-working days, prior to and during rain events. 7. Keep material storage areas clean, organized and equipped with an ample supply of appropriate spill clean-up material (spill kit). 8. The spill kit should include, at a minimum: • 1-Water Resistant Nylon Bag • 3-Oil Absorbent Socks 3″ x 4′ • 2-Oil Absorbent Socks 3″ x 10′ • 12-Oil Absorbent Pads 17″ x 19″ • 1-Pair Splash Resistant Goggles • 3-Pair Nitrile Gloves • 10-Disposable Bags with Ties • Instructions CSWPP – Renton SW 19th Street Road Widening and SW 18th Street Roundabout 29 CONSTRUCTION STORMWATER CHEMICAL TREATMENT Not Applicable CONSTRUCTION STORMWATER FILTRATION Not Applicable HIGH PH NEUTRALIZATION USING CO2 Not Applicable PH CONTROL FOR HIGH PH WATER Not Applicable USE OF HIGH PH SOIL AMENDMENTS ON CONSTRUCTION SITES Not Applicable CSWPP – Renton SW 19th Street Road Widening and SW 18th Street Roundabout 30 MAINTAIN PROTECTIVE BMPS Pollutant protection measures shall be maintained to ensure continued performance of their intended function. Reporting and documentation shall be kept current and made available to CED as indicated. Purpose The purpose of maintaining protective BMPs is to provide effective pollutant protection when and where required by the plan and the project, and to provide timely and relevant project information. When to Maintain Protection measures shall be monitored per Section D.2.4.4 at a minimum, continuously during operation, and promptly maintained to fully functioning condition as necessary to ensure continued performance of their intended function. Documentation shall be kept current per specific BMP requirements. Measures to Use: 1. Maintain and repair all pollutant control BMPs as needed to ensure continued performance of their intended function in accordance with BMP specifications. 2. Maintain and repair storage locations for equipment and materials associated with BMP processes. Conduct materials disposal in compliance with City requirements. 3. As required, provide current reporting and performance documentation at an accessible location for the site inspector and other CED staff. 4. Remove all temporary pollutant control BMPs prior to final construction approval, or within 30 days after achieving final site stabilization or after the temporary BMPs are no longer needed. CSWPP – Renton SW 19th Street Road Widening and SW 18th Street Roundabout 31 MANAGE THE PROJECT SWPPP requirements shall be implemented and managed as part of the overall CSWPP plan. Concrete construction and its impacts are primary among pollutant concerns on site development projects. Fueling operations and materials containment of treatment chemicals and other project materials are also typical pollutant concerns. Operations that produce these and other pollutants are often conducted by subcontractors and their laborers, yet may require specific protective measures, documentation and reporting. Protective measures and BMPs need to be made available prior to construction and suitable oversight provided to ensure inspection, monitoring and documentation requirements are met. Projects shall assign a qualified CSWPP Supervisor (Section D.2.3.1) to be the primary contact for SWPPP and ESC issues and reporting, coordination with subcontractors and implementation of the CSWPP plan as a whole. Measures to Use: 1. Phase development projects to the maximum degree practicable and take into account seasonal work limits. 2. Inspection and monitoring – Inspect, maintain, and repair all BMPs as needed to ensure continued performance of their intended function. Conduct site inspections and monitoring in accordance with the Construction Stormwater General Permit and City requirements. Coordinate with subcontractors and laborers to ensure the SWPPP measures are followed. 3. Documentation and reporting – Inspect, maintain, and repair all BMPs as needed to ensure continued performance of their intended function. Document site inspections and monitoring in accordance with the Construction Stormwater General Permit, specific BMP conditions and City requirements. Log sheets provided in Reference Section 8 may be used if appropriate. Follow reporting requirements and provide documentation as requested to CED staff. 4. Maintaining an updated construction SWPPP – Maintain, update, and implement the SWPPP in accordance with the Construction Stormwater General Permit and City requirements. Obtain approval for specific SWPPP measures (e.g., chemical treatments of stormwater) well in advance of need. Coordinate SWPPP plan updates with the site inspector (see Section D.2.4.1). CSWPP – Renton SW 19th Street Road Widening and SW 18th Street Roundabout 32 4.0 Spill Prevention and Cleanup Plan It is critical for the CSWPP Supervisor to have their employees trained, and have a plan and supplies in place to address spills that might occur on or near your property. A spill plan identifies the materials of concern and outlines the steps to be taken when responding to a spill. The nature of the business, the type and amount of liquid materials transferred and stored on-site, and the potential for spills will dictate the scope and detail of a spill plan. It is critical that the CSWPP Supervisor keeps the plan up to date to reflect personnel and procedural changes and to have a regular, ongoing review of the plan by all affected employees. Form templates are provided in Appendix C to aid in the preparation of a spill plan. Spill plans should include the following elements: • Identification of materials of concern • Spill prevention methods (if you don’t have a site pollution prevention plan) • Likely areas for spill or leaks to occur • Site plan that identifies the locations of liquid material storage and spill control equipment • Spill control techniques • Evacuation procedures (if necessary) • Cleanup procedures • Designated responsible employees • Spill reporting protocols • Emergency contact numbers Even if unsure whether a spill presents a threat to human health, welfare, or the environment, go ahead and report it. This will ensure that you have complied with state and federal spill reporting laws. The sooner the agencies know about an incident, the quicker they can deploy resources and assistance to reduce damage to the environment and protect natural resources.
