This application is used for variety of projects; therefore, not all items may be necessary. Additional applications and
supplemental forms that may be required, as well as helpful handouts, are found online at
https://www.skagitcounty.net/Departments/PlanningAndPermit/forms.htm.
PLEASE PRINT APPLICATION ONE-SIDED
.
An application is required for each separate structure. Prior to
submittal, please check online for form updates, as they may have changed during your project planning.
Step 1:
Prior to turning in this application, please review the Building Permit Application Checklist on the next page. Depending
on your project’s scope, additional approvals may be required before intake of your application. Applications are
arranged on the checklist to move you through the process as efficiently as possible. Most items on the checklist, with
the exception of SEPA, variances, or special use permits are reviewed by our department within an estimated two
weeks. SEPA, variances, and special use permits may be applied for concurrently with the building permit, but at the risk
of the applicant if the application is not approved.
Items 1-10 must be applied for and approved (if required) before building permit application submittal.
Items 1-9 can be applied concurrently. Appointments are required if submitting more than two applications.
Item 10 requires that a lot certification and critical area review have been completed prior to submittal of a new
septic design. This ensures the system is being placed on a legal lot of record and not being placed in a critical area.
Step 2:
Once items 1-10 are approved and you have completed items 11-16, please schedule an appointment with a Permit
Technician at the phone number listed above. Appointments are available Monday through Friday and are a one hour
time slot where the application will be reviewed for completeness. A plan check fee will be required at submittal.
Items 11-17 make up the building permit application packet. These items are required for submittal.
Helpful Tips:
Inquire about timeframes when planning your project and specify submittal date. Timeframes vary seasonally.
Permits are valid for three years. If you cannot complete your project, you can request in writing a six month
extension for free OR pay a renewal fee for a three year extension (SCC 15.04.020 Section 105.5).
Do you need an estimate for your permit, other application costs, or impact fees? Ask a Permit Technician!
Determine your project’s zoning designation and read about it in the Skagit County Code. Your zoning designation
will tell you if your project is permitted or if you need a special use permit, setbacks for your project, lot coverage
and special conditions that may apply to your project. If your property is in a plat, read your plat notes.
If you revise your project after submittal, there will be a $120/hr of review fee added to your file. A revision will also
add additional time on to your project, so please plan accordingly.
If the review time goes past the estimate given at submittal, and you have not been contacted for more information,
please do not hesitate to call us to inquire.
Permit Technicians are available to assist with questions during Permit Center counter hours or by phone/email.

Statement
This parcel lies within an area or is within 500 feet of an area designated as a natural resource land (agricultural,
forest, and mineral resource lands of long-term commercial significance) in Skagit County. A variety of natural
resource land commercial activities occur or may occur in the area that may not be compatible with non-resource
uses and may be inconvenient or cause discomfort to area residents. This may arise from the use of chemicals; or
from spraying, pruning, harvesting, or mineral extraction with associated activities, which occasionally generates
traffic, dust, smoke, noise, and odor. Skagit County has established natural resource management operations as a
priority use on designated natural resource lands, and area residents should be prepared to accept such
incompatibilities, inconveniences, or discomfort from normal, necessary natural resource land operations when
performed in compliance with best management practices and local, State, and Federal law. In the case of mineral
lands, application might be made for mining-related activities including extraction, washing, crushing, stockpiling,
blasting, transporting, and recycling of minerals. In addition, greater setbacks than typical may be required from the
resource area, consistent with SCC 14.16.810. Contact Skagit County Planning and Development Services for details.

This workshee
t is required if your project adds ANY impervious/hard surface or disturbs ANY of the land
on your property. The amount of impervious/hard surface or land disturbance on your parcel correlates to
the amount of stormwater it will generate, and its potential impact on downstream properties. Stormwater requirements are
determined based on where the project is occurring and how much disturbance is taking place. Answer the information below to
determine what stormwater requirements apply to your project.
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.
Attachments, if required by this worksheet
Stormwater Pollution Prevention Plan (SWPPP) See Part 2.
Best Management Practices (BMPs) for stormwater components, such as infiltration trench, drywell, rain garden, etc.
Plat notes and/or stormwater report for the property. Sitespecific limitations, including plat design, variances, geotechnical
reports, etc. may be more restrictive than the thresholds and requirements represented in this worksheet.
Part 1 Project Site Details
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.

Part 4b Limited Stormwater Planning
Essential Stormwater Management Techniques Requirement
Stormwater from roofs and hard surfaces must be managed. See Stormwater Sizing and Design Guidelines for methods.
To reduce the stormwater you generate, consider the following:
2
Limit clearin
g and grading to the minimum necessary for construction of permitted uses and associated utilities.
Limit lawn areas, driveways, and roads and locate them in a manner that results in the least disruption to the
topography and native vegetation on the site.
Cluster lots, dwelling units, or building structures during the conceptual planning stage to preserve open space, reduce
total impervious surface area, and minimize development impacts on critical areas and associated buffers.
If your parcel is one acre or larger and your project proposes 7,000 sq ft of new plus replaced hard surface, or 14,000 sq ft
or more of land disturbing activity, you must also fully comply with Stormwater Management Manual Minimum
Requirement 4 to preserve natural drainage.
Part 4c Floodplain LID Compliance
LID is a storm water management strategy that emphasizes conservation and the use of existing natural site features by integrating
them with distributed, small
scale storm water con
trols to mimic natural hydrologic patterns. LID also captures and stores water for
later reuse, filters out pollutants, and reduces water velocities during storm events.
Impervious surface sh
all not exceed 10% of surface area of the portion of the lot in the SFHA unless demonstrated that there
will be no net increase in the rate and volume of stormwater surface runoff that will leave the site or that the impact is
mitigated.
1
Low Impact Dev
elopment (LID) techniques must be used where technically feasible to minimize or avoid stormwater effects.
See Stormwater Sizing and Design Guidelines for methods.
Low Impact Development
(LID) techniques that primarily focus on infiltration may not be feasible in portions of some
floodplains due to factors such as high groundwater soil quality, slope, drainage, and vegetative cover type. Thus, even where
infiltration is not feasible, other LID techniques may be used that focus on water quality (rainwater collection and reuse,
vegetation retention, and bioswales). See the Infiltration Test Worksheet to determine through testing if infiltration is feasible.

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).

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.

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

BMP C235: Wattles
Purpose
Wattles are temporary erosion and sediment
control barriers consisting of straw, compost, or
other material that is wrapped in biodegradable
tubular plastic or similar encasing material. They
reduce the velocity and can spread the flow of rill
and sheet runoff, and can capture and retain
sediment. Wattles are typically 8 to 10 inches in
diameter and 25-30 feet in length. Wattles are
placed in shallow trenches and staked along the
contour of disturbed or newly constructed slopes.
Conditions of Use
Use wattles:
In disturbed areas that require immediate
erosion protection.
On exposed soils during the period of
short construction delays, or over winter
months.
On slopes requiring stabilization until
permanent vegetation can be established.
The material used dictates the effectiveness
period of the wattle. Generally, Wattles are
typically effective for one to two seasons.
Prevent rilling beneath wattles by properly entrenching
and abutting wattles together to prevent water from
passing between them.
Design Criteria
Install wattles perpendicular to the flow direction and
parallel to the slope contour.
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
areas with high rainfall, the trenches should be dug to a
depth of 5- to 7- inches, or 1/2 to 2/3 of the thickness of
the wattle.
Start building trenches and installing wattles from the
base of the slope and work up. Spread excavated
material evenly along the uphill slope and compacted
using hand tamping or other methods.
Construct trenches at intervals of 10- to 25-feet
depending on the steepness of the slope, soil type, and
rainfall. The steeper the slope the closer together the
trenches.
Install the wattles snugly into the trenches and abut
tightly end to end. Do not overlap the ends.
Install stakes at each end of the wattle, and at 4-foot
centers along entire length of wattle.
If required, install pilot holes for the stakes using a
straight bar to drive holes through the wattle and into
the soil.
Wooden stakes should be approximately 3/4 x 3/4 x 24
inches min. Willow cuttings or 3/8-inch rebar can also be
used for stakes.
Stakes should be driven through the middle of the
wattle, leaving 2 to 3 inches of the stake protruding
above the wattle.
Maintenance Standards
Wattles may require maintenance to ensure they are in
contact with soil and thoroughly entrenched, especially
after significant rainfall on steep sandy soils.
Inspect the slope after significant storms and repair any
areas where wattles are not tightly abutted or water has
scoured beneath the wattles.

Driveway Standards for Skagit County
Planning & Development Services · 1800 Continental Place · Mount Vernon WA 98273
voice 360-416-1320 · inspections 360-416-1330 · www.skagitcounty.net/planning
A driveway to serve residential or commercial uses must meet the following standards from the International Fire Code.
1
These
standards are the minimum and apply to all building permits. Roads within a new subdivision must comply with the
Skagit County
Road Standards.
When Fire Access is Required
You must provide a fire apparatus access road for every facility, building, or portion of a building constructed or moved into or
within the jurisdiction when the facility is over 150 feet from a fire apparatus access. Exceptions may be made for minor additions or
accessory buildings to existing dwellings when in the opinion of the Fire Marshal the addition or accessory building may not create
significantly dangerous situations.
General Design Standards
The standards on the left apply to driveways serving 1-2 residential lots. The standards on the right apply to private roads that serve more than two
lots must comply with the Skagit County Road Standards.
Standards Based on Grade
All residential and commercial driveways must meet these standards.
Notes
The Fire Marshal may make modifications to these standards if the road is not buildable because of topography, waterways, non-negotiable grades, or similar
conditions. These modifications are based on the building being protected by NFPA 13D automatic sprinkler systems, and additional fire protection as required by
the Fire Marshal.
For roads accepted or platted by Skagit County prior to June 11, 1990, the Fire Marshal may modify these standards if firefighting or rescue operations would still
be possible.
For lots not in a fire district and accessible only by water, the access road requirement may be waived if the project meets all of the other requirements of Skagit
County Unified Development Code to qualify for a building permit.
Emergency vehicle access roads or driveways may not be obstructed in any manner, including vehicle parking. Width and clearance requirements consistent with
these standards must be maintained at all times.
Security gates across fire access roads must be approved by the Skagit County Fire Marshal. Security gates must have an approved means of emergency
operation by fire personnel.
