1.0 Project Overview
Project improvements are being proposed at two separate areas of work. 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

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.

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.

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.

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.

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.

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.

8.0 CSWPP Analysis and Design
An Erosion and Sedimentation Control (ESC) plan will be developed for the contract plans per
the 2022 RSWDM.
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.

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.

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.

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

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.

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.

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

• 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.

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’

SAWCUTTING AND SURFACING POLLUTION PREVENTION
Purpose
Sawcutting and surfacing operations generate slurry and process water that contains fine
particles and high pH (concrete cutting), both of which can violate the 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 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

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).

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.

SPILL RESPONSE AND CLEANUP PL AN, CONTINUED
SPILL REPORTING
Stop, contain, and clean up the chemical spill if: ❑ The spilled chemical and its hazardous properties have been identified; ❑ The spill is small and easily contained; and ❑ The responder is aware of the chemical’s hazardous properties.
Spill clean up ❑ Alert the manager/owner of property where the spill has occurred. ❑ Obtain personal protective equipment, as appropriate to the hazards. Refer to the Material Safety Data
Sheet or other references for information. ❑ Stop the source of the spill (upright container, plug leak, etc.). ❑ Seal off storm drains with berms or drain covers and stop any spread of the spill. ❑ Protect floor drains or other means for environmental release. Spill socks and absorbents may be placed around drains, as needed. ❑ Use pads and/or granular sorbent to clean up spilled material. Loose spill–control material should be
distributed over the entire spill area, working from the outside, circling to the inside. When spilled materials
have been absorbed, use brush and scoop to place materials in an appropriate container. ❑ Let pads sit on spill to absorb spilled material. ❑ Remove spent pads and/or sorbent and dispose of properly.
If a spill or release cannot be controlled or injuries have occurred due to the release the following procedures should be implemented: ❑ Summon help or alert others of the release; ❑ Evacuate the immediate area and provide care to the injured – Call 911; ❑ If potential fire or explosion hazards exist, initiate evacuation procedures – Call 911; ❑ Respond defensively to any uncontrolled spills: ❑ Use appropriate personal protective equipment when responding to any spill; ❑ Attempt to shut off the source of the release (if safe to do so); ❑ Eliminate sources of ignition (if safe to do so); ❑ Protect drains by use of adsorbent, booms or drain covers (if safe to do so). ❑ Notify the onsite emergency contacts; ❑ Notify other trained staff and/or emergency response contractors to assist with the spill response and
cleanup activities; ❑ Be prepared to provide MSDS information to the fire department, EMT, hospital or physician; ❑ Notify the appropriate agency if a release has entered the environment. Refer to the Spill Reporting Table
for reporting thresholds.
