About this Pollution Prevention Plan
This is Anacortes’s Small Site Construction Stormwater
Pollution Prevention Plan (“Construction SWPPP”)
intended to ensure your construction project minimizes
erosion and does not contribute pollution, including
sediment, to stormwater. This SWPPP is primarily
intended for projects under 2,000 sq ft.
This plan uses certain Best Management Practices
(“BMPs”) from the Stormwater Management Manual.
Some detailed descriptions are included; the remainder
and additional information are available at
https://fortress.wa.gov/ecy/publications/parts/1410055pa
rt4.pdf#page=27 The listed BMPs are the minimum
necessary; if erosion occurs, you must add
additional BMPs as necessary to control it.
You should include your Construction SWPPP in your
contract with your builder. You must keep a copy of this
SWPPP on the construction site or within reasonable
access to the site for construction and inspection
personnel at all times.
Property owners and contractors are responsible for
ensuring all aspects of BMPs are followed, including
those not shown on the detail sheets. This Construction
SWPPP should be considered a living document and
must be updated as needed to reflect site conditions.
Preserve Vegetation/Mark Clearing Limits
Before any land disturbance, including clearing and
grading, clearly mark all clearing limits, sensitive areas
and their buffers, and trees that are to be preserved
within the construction area. Retain natural vegetation in
an undisturbed state to the maximum extent practical.
Use these BMPs:
•C101 to preserve natural vegetation
•C102 to establish buffer zones around important
vegetation you want to save
•C103 High Visibility Fencing to mark the
boundaries of your buffers
•C233 Silt Fence to ensure sediment doesn’t leavethe site
Establish Construction Access
Construction vehicles can damage or compact
soils, create sediment pollution, or track sediment
onto public roads.
All equipment and vehicles that access the construction
area must use an existing driveway or a stabilized
construction entrance.
•Use BMP C105 Stabilized Construction Entrance
wherever traffic will be entering or leaving a
construction site if paved roads are within 1,000 ft of
the site. Construct a 12-inch thick pad of 4-inch to 8-
inch quarry spalls, a 4-inch course of asphalt treated
base, or use existing pavement. Place a separation
geotextile under the spalls to prevent fine sediment
from pumping up into the rock pad. Install the
construction entrance prior to any vehicles entering
the site, at the location shown on the site plan.
Create only one construction entrance per site.

•Use BMP C103 High Visibility Fencing to restrict
traffic to the construction entrance.
•Remove any sediment that is tracked onto pavementby shoveling or street sweeping and remove the
collected sediment or stabilize it on site.
Control Flow Rates (not shown)
Stormwater on a cleared site can create significant
flows that can damage downstream properties.
Protect properties and waterways downstream of the
project site from erosion and the associated discharge of
turbid waters. If your project is required to control flow
rates, you must use the following BMPs as shown on the
approved site plan:
•C203 Water Bars
•C209 Outlet Protection
•C235 Straw Wattles
Install Sediment Controls
When land is cleared of vegetation, stormwater can
pick up sediment, a pollutant. BMPs can prevent
sediment from leaving the site.
You must install sediment controls before land
disturbance to effectively minimize and control the
discharge of pollutants and sediments.
Use and properly install BMP C233 Silt Fence. You
must bury the filter fabric as shown in the diagram in
order for the BMP to be effective. You must repair the silt
fence if it is damaged.
Consider the following additional BMPs:
•C231 Brush Barrier
•C232 Gravel Filter Berm
•C234 Vegetated Strip
•C235 Straw Wattles
Note that C230 Straw Bale Barrier is no longer an
approved BMP.
Stabilize Soils
Leaving soils devegetated or exposed needlessly
creates erosion and sediment problems.
•Stabilize all exposed soils whenever constructionwork will stop for more than two days at a time during
the wet season (October 1 to April 30) or 7 days the
rest of the year (the dry season).
•Stabilize all exposed soils at the end of the shift
before a holiday or weekend.
•Stabilize all exposed soils with either vegetation, matcoverings, mulching, or in those areas to be paved, a
compacted base material.
•Use BMP C123 Plastic Covering over all stockpiles
with plastic or burlap if left unworked. Place sand-
filled burlap or geotextile bags every 3 to 6 ft along
seams and tie them together with twine to hold them
in place.
•If you excavate soil for the foundation, backfill that
soil against the foundation and grade it to drain away
from the building. Once the disturbed landscape
areas are graded, you must seed or sod the grass
areas.
Consider the following additional BMPs:
•C120 Temporary and Permanent Seeding
•C121 Mulching
•C122 Nets and Blankets
•C124 Sodding
•C125 Topsoiling/Composting
•C131 Gradient Terraces
•C140 Dust Control
Protect Slopes (not shown)
Slopes can be especially vulnerable to erosion, but
BMPs can mitigate sediment problems.
Design and construct cut-and-fill slopes to minimize
erosion. Use the following practices:
•Reduce continuous length of slope with terracing and
diversions
•Reduce slope steepness
•Roughen slope surfaces
•Use BMP C123 Plastic Covering over all exposed
slopes
•Use BMP C120 Temporary and Permanent Seeding
as soon as possible on exposed slopes
Manage off-site stormwater (run-on) separately from
stormwater generated onsite. Divert off-site stormwater
or groundwater away from slopes and disturbed areas
with interceptor dikes, pipes, or swales.
You may not create cut slopes over 4 feet high or slopes
steeper than 2 feet horizontal to 1 foot vertical. Fill
slopes may not exceed 4 feet high or 3 feet horizontal to
1 foot vertical. Slopes that exceed these criteria require
engineering.
Consider the following additional BMPs:
•C121 Mulching
•C122 Nets and Blankets
•C124 Sodding
•C203 Water Bars
•C208 Triangular Silt Dike (Geotextile‐Encased Check
Dam
Protect Drain Inlets
Storm drains are designed to collect and transport
clean stormwater, not water contaminated with
sediment or other pollutants. Storm drain inlets
must be protected so that runoff does not enter the
3
4
5
6
7
Small Site Construc�on SWPPP (002) Updated 4/23/2024 page 5 of 6
stormwater system without first being filtered or
treated or both.
•Use BMP C220 Storm Drain Inlet Protection to
protect all proposed and existing storm drain inletsduring construction so that stormwater runoff does
not enter the stormwater conveyance system without
first being filtered or treated (or both) to remove
sediment or other pollutants.
•Clean or remove and replace inlet protection devices
when sediment has filled one-third of the available
storage (unless a different standard is specified by
the product manufacturer).
•Keep all approach roads clean.
•Do not allow sediment and street wash water to enter
storm drains without treatment.
Stabilize Channels and Outlets
Stormwater channels and outlets can themselves
erode unless stabilized with rock or other armoring.
Design, construct, and stabilize all on-site conveyance
channels to prevent erosion as needed. Use BMP C209
Outlet Protection to provide stabilization, including
armoring material adequate to prevent erosion of outlets,
adjacent streambanks, slopes, and downstream reaches
at the outlets of all conveyance systems.
Consider the following additional BMPs:
•C122 Nets and Blankets
•C202 Channel Lining
Control Pollutants
Waste materials, demolition debris, and other
pollutants that occur onsite during construction can
contaminate the stormwater system unless
managed. Cement and related products can modify
the pH of stormwater.
Provide cover, containment, and protection from
vandalism for all chemicals, liquid products, petroleum
products, and other materials that have the potential to
pose a threat to human health or the environment.
Anytime you pour concrete, perform washout of the
concrete trucks following BMP C154 Concrete Washout
Area at designated washout areas only. Locate washout
areas at least 50 ft from sensitive areas such as storm
drains, open ditches, or water bodies, including
wetlands.
Clean contaminated surfaces immediately following any
spill incident. Apply fertilizers and pesticides in a manner
and at rates that will not result in loss of chemical via
stormwater runoff.
Use the following additional BMPs:
•C151 Concrete Handling
•C152 Sawcutting and Surfacing Pollution Prevention
•C153 Material Storage, Delivery, and Containment
Control De-Watering (not shown)
De-watering water extracted from foundations,
vaults, or trenches, has similar characteristics to
stormwater runoff at the site and can cause the
same impacts unless properly managed.
You may discharge clean, non-turbid de-watering, such
as well-point ground water, to systems that are
tributaries to, or directly into, surface waters if the de-
watering flow does not cause erosion or flooding or
interfere with the operation of the stormwater system.
Use the following BMPs:
•C220 Storm Drain Inlet Protection
•C236 Vegetative Filtration
Maintain BMPs (not shown)
All temporary and permanent erosion and sediment
control BMPs must be maintained and repaired as
needed to assure continued performance of their
intended function.
During the dry season, inspect sediment control BMPs
weekly or after a runoff-producing storm event. During
the wet season, inspect BMPs daily. Use BMP C150
Materials on Hand to ensure you are ready for a heavy
rain.
All temporary erosion and sediment control BMPs must
be removed within 30 days after the City determines that
the site is stabilized or after the temporary BMPs are no
longer needed. Trapped sediment must be removed or
stabilized on site. Disturbed soil areas resulting from
removal of BMPs or vegetation must be permanently
stabilized.
Manage the Project (not shown)
Phasing a project, especially when revegetation
occurs as part of each phase, can help prevent the
transport of sediment from the site.
•Fully implement this Construction SWPPP at all
times.
•Modify this Construction SWPPP whenever there is a
change in design, construction, operation, or
maintenance at the construction site that has or could
have a significant effect on the discharge of
pollutants to waters of the state.
•Inspect, maintain, and repair all BMPs as needed to
ensure continued performance of their intended
function.
