Staff Use Only:
Background
A grading permit may be necessary whenever grading (any excavation or filling) is being done in Skagit County. Appendix J of the International Building
Code sets forth rules and regulations to control excavation, grading and earthwork construction including fills and embankments, establishes the
administrative procedure for issuance of permits and provides for approval of plans and inspection of grading construction. The following information
is required for all applications. Use the attached checklist to determine if your application is complete. This checklist outlines a minimum amount of
information needed for review of your application. Additional information, which may be required, can substantially reduce review time.
Flood Hazard Area
Fill and grading is restricted in specific flood risk zones and areas of flood hazard. Engineering analysis may be required to determine impact on flood
flows (water displacement). See Skagit County Code Title 14.34 - Flood Damage Prevention for details.
Fill to Support a Structure
If the fill is intended to support a structure, you must submit construction details/plans of fill placement including type of materials, depth differences
and expected bearing and lateral capacity after completion. Special inspection/compaction report from a qualified agency will be required at the time
of building permit application.’ If the fill or grading is expected to be placed/excavated adjacent to an existing or proposed structure, an engineer’s
design illustrating that the building or structure is capable of withstanding additional loads is required.
Tree removal and Forest Practices
Fill and grading activities are commonly associated with even minor logging activities. Individuals wishing to remove trees from their property
should first check with the Department of Natural Resources (DNR) at (360) 856-3500 to determine if a Forest Practice Application (FPA) is required.
If an FPA is needed, and if future plans include a single-family residence or some other type of development approval (such as a short plat,
subdivision or Special Use Permit), then Skagit County’s permit requirements must be applied as part of the FPA.
Forest Practice Conversions
Permit requirements include fill and grading activities commonly associated with the early stages of development, Forest Practice Application (FPA)
form to the DNR, (not the County). If future plans for the site include conversion for future development, a SEPA (State Environmental Policy Act)
checklist must also be filed with the FPA. DNR has its own fee schedule.

Directions
Use the categories to help define your hard surface areas. Use the “Other” lines as needed.
It is important to count all surfaces and that measurements are consistent with your site plan
.
Fill in the square footage of existing hard surfaces that you do not intend to alter.
If you plan to create new hard surface OR replace existing hard surfaces with new hard surfaces, list those amounts in column 3.
If you plan to REMOVE hard surfaces as part of your project and not replace them, list those as negative amounts, using the
“Other” lines as necessary.
Helpful Definitions
• Hard surface means an impervious surface, a permeable pavement, or a vegetated roof.
• Impervious surface means a non‐ vegetated surface area that either prevents or retards the entry of water into the soil mantle
as under natural conditions prior to development. A non‐vegetated surface area, which causes water to run off the surface in
greater quantities or at an increased rate of flow from the flow present under natural conditions prior to development.
Common impervious surfaces include, but are not limited to rooftops, walkways, patios, driveways, parking lots or storage
areas, concrete or asphalt paving, gravel roads, packed earthen materials, and oiled, macadam or other surfaces, which similarly
impeded the natural flow of stormwater. SCC 14.04.020.
• Land Disturbing Activity means any activity that result in a change in the existing soil cover (both vegetative and nonvegetative)
or the existing soil topography, including clearing, grading, filling and excavation.

About this Pollution Prevention Plan
This is Skagit County’s model 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 Model SWPPP is primarily intended for
single-family residential construction.
This plan uses certain Best Management Practices (“BMPs”)
from the Stormwater Management Manual. Some detailed
descriptions are included; the remainder are available at
www.skagitcounty.net/stormwaterpermitting. 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 leave the 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 pavement by
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 devegetated, 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 construction work 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).
1
2
3
4
5
• Stabilize all exposed soils at the end of the shift before a
holiday or weekend.
• Stabilize all exposed soils with either vegetation, mat
coverings, 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 Blnakets
• 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 polluted with sediment or other
pollutants. Storm drain inlets must be protected so that
runoff does not enter the 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 inlets during
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.
6
7
8
9
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 County 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.
Protect Low-Impact Development BMPs
Low-Impact Development techniques can be damaged if
they are compacted or accumulate sediment during
construction.
If there are any Low-Impact Development BMPs planned for
the site:
• Use BMP C103 High Visibility Fence to exclude all
construction and foot traffic from the infiltration, bio-
retention, or rain garden areas.
• Protect all infiltration areas or bio-retention and rain
garden BMPs from sedimentation through installation and
maintenance of erosion and sediment control BMPs on
portions of the site that drain into those areas.
• Use BMP C233 Silt Fence or C234 Vegetated Strip to
control and avoid introducing sediment onto permeable
pavements. Bury the bottom of the filter fabric at least 4
inches below the ground surface. Backfill and tamp soil in
place over the buried portion of the filter fabric, so that
no flow can pass beneath the fence and scouring cannot
occur. Drive or place the fence posts into the ground at
least 18 inches. A 12-inch minimum depth is allowed if
topsoil or other soft subgrade soil is not present and 18
inches cannot be reached.
• If pavements are fouled with sediments or no longer pass
an initial infiltration test, clean them using procedures
from the Stormwater Manual or the manufacturer’s
procedures.
Consider the following additional BMPs:
• C102 Buffer Zones
• C208 Triangular Silt Dike
• C231 Brush Barrier

8. Septic/Sewer
Method of sewage disposal
For public sewer, show:
location of sewer main
private pipes to buildings
For private septic, show existing and proposed:
Tanks (must be 5' from the building foundation, 5’ from property lines, and 50' from any well)
Drain fields (must be 10' from the building foundation, 5’ from property lines and 100' from any well)
Lines/pipes
9. Slope
Existing slopes and area/depth of any proposed site grading or fill. Label existing slopes as “existing” or “Ex”
Proposed final slope(s) of building site using contour lines or arrows to show direction and percent of slope(s).
Percentage % of slope = rise (change in elevation) divided by run (distance) multiplied by 100.
Identify any erosion or landslide areas and any potentially unstable slopes greater than 15%
10. Stormwater and Temporary Erosion & Sedimentation Control (TESC)

Rainwater catchment systems
Trees 12”diameter or larger, on or adjacent to the site, in the vicinity of stormwater components
Temporary erosion and sediment control (“TESC”) techniques:
Work/clearing limits: a boundary defining the limit of the work area, and those areas to be protected.
Examples of areas to be protected include trees, stormwater infiltration areas, and wetlands.
Location & type of TESC BMP: Show location of all applicable TESC best management practice (BMP)
facilities. See also Stormwater Pollution Prevention Plan (SWPPP).
Location of stabilized construction entrance; minimum of 25 feet long for residential projects, minimum
100 feet long for all other project types.
Location of porta-pottie(s); should be at least 25 feet away from any storm inlets or critical areas
Location of materials stockpiles, equipment and supply staging area. Areas to be used for septic
drainfields and stormwater infiltration should be protected and avoided.
