Mi'iiirfiiim Req : Construction Stormwater Pollution Prevention Plan (SWPPP)
A SWppp is designed to be a stand-alone document that addresses ggnstruction stormwater management concerns. This
document is required to be kept by the contractor performing the work at the jobsite for reference and update during
the life of the project. WORKSHEETS 81 and 82 are provided to meet this minimum requirement.
E ,, completed swppp (WoRKSHEETS 81 & 82 or equivalent) is included in this application packet!
Minimum Requirement # 3 : Source Control of Pollution (not construction related)
The intent of source control is to prevent stormwater from coming in contact with pollutants. Source control BMPs
can be operational or structural in nature. A roof over a material storage area is an example of a structural source
control BMp. Washing your vehicle on the lawn rather than in the street is an operational BMP. This requirement is
generally not applicable to Single Family Residences (SFRs); however, ways to minimize pollution from mobilizing
downstream should be considered during the design phase of every project. Specifications on standard source control
BMps that are applicable to various commercial and industrial-type facilities can be found in Volume lV of the 2014
Stormwater Management Manual for Western Washington (SWMMWW)'
Check one of the following boxes that best represents your project with regards to MR #3
E My project is a Single Family Residence (SFR) and after considering operational and structural measures
to prevent stormwater from coming in contact with pollutants, I have:
pdetermined this MR to not be applicable. fl made appropriate adjustments to my project.
My project is not a SFR and after reviewing Vol. lV of the SWMMWW I have determined that this MR is
not applicable because of the followi reason

Minimum Requirement # 4 : Preservation of Natural Drainage syste MS
Creating new drainage patterns results in more site disturbance and more potential for erosion and sedimentation during
and after construction. Proponents must achieve the following to the maximum extent possible:
1) maintain the natural on-site drainage pattern and concentrated discharge tocation
at the downstream property boundary and
2) prevent erosion at and downstream of the discharge location. NOTE: All outfalls require energy dissipation
See Table 4.5.1 in Vol. V of the SWMMWW for minimum design standards for rock protection at outfalls.
Choose the option below that best describes your project:
F] The proposed project site does not currently have any intermittent, seasonal, or continuous concentrated
water moving across any part of the property and the proposed improvements to the site will not create
new concentrated flow paths. There are no new discharge locations OR the new discharge locations
being proposed are a result of navigating through MR #5 requirements, measures have been taken
to dissipate the discharge energy at the outfall, and the runoff will be discharged into a pre-existing
stormwater conveyance system (ie: ditch, curb line, storm pipe, etc.).
The proposed project site has existing concentrated flow drainage systems and outfalls. (NOTE: These
items must be graphically shown on the Site Plan, WORKSHEET A2 or equivalent, to include: type, slope,
dimensions, channel lining, direction of floW buffer, etc.) Select below how it will be addressed.
This project will not alter the existing drainage system in any way. lf the existing outfall(s)
show signs of erosion and scour, energy dissipation measures will be installed or improved
upon. Construction activity of any kind will not occur within at least 10 ft. of the edge of the
channelized flow. BMP C1O2: BUFFER ZONES will be implemented during the life of the project to
include visible flagging or other demarcation technique.
n The existing concentrated drainage system traversing the property will be impacted as part of
this project, as described in the space below and shown on the site plans. While impacted, the
natural drainage pattern and discharge location has been maintained to the maximum extent
practical. lf applicable, engineering calculations are provided that show the altered drainage
design can accommodate the existing flows and the added runoff contributed by the project.

nequirernent # 5 : O n-s ite Sto rmwate r M a n a ge me nt
On-site stormwater management techniques be implemented where possible to accommodate the permanently
added stormwater runoff being generated by development. Some on-site stormwater management
techniques provide better stormwater detention and treatment than others; however, they are not always appropriate
for use due to varying individual site characteristics. Therefore, techniques are presented to applicants on the next
pages in a hierarchical order and shall be considered for use in the order listed. The first technique on the list that
is determined to be feasible shall be implemented. Any technique considered and subsequently determined to be
infeasible requires the applicant's justification to be documented, see WORKSHEET C.
Additionally, runoff from developments occurring in drainage basins that drain directly or indirectly to a creek require a
higher level of stormwater management, thus, the techniques are presented in two lists: LIST #1) applicable to projects
that drain to directly or indirectly to a freshwater watershed and LIST #3) applicable to projects that drain to saltwatel
the Dosewallips Rive6 Hoh River; Queets River, or Lake Quinault.
My project is located in a drainage basin that drains

The Federal Endangered Species Act rules to protect threatened Chinook and Summer-run Chum salmon
became effective on January 8, 2001. Bull trout have been listed as threatened since early 2000. Under
the ESA, any person may bring lawsuit against any individual or agency that "takes" listed species (defined
2013-03-07 SFR Stdconditions 3/7/2OI3 1
o
as causing harm, harassing, or damaging habitat for the listed species). ln addition, the National Marine
Fisheries Service can levy penalties. Portions of Jefferson County, including marine waters, are included
as "critical habitat" for a listed species. Development of property along any marine shoreline, freshwater
shoreline,
or floodplains could harm habitat if protective measures are not taken. To minimize the potential to
damage habitat, all property owners developing adjacent to marine shoreline, freshwater shoreline, or
floodplains are advised to do the following:
All development activities should avoid unstable slopes, wetlands, and forested areas near surface
waters
Remove minimal vegetation for site development, especially large trees
Allow trees that have fallen into surface waters to remain there
lnfiltrate stormwater from buildings and driveways onsite through drywells rather than discharging
directly into surface waters or roadside ditches
The Federal Bald and Golden Eagle Protection Act requires landowners within 660 feet (1/8th of a mile) of
an eagle nest to consult with the US Fish and Wildlife Service. This Eagle Act prohibits anyone from
"taking" bald eagles. This federal law defines the term "take" and describes the possible legal
consequences when a "take" occurs. Among other actions, "take" includes a disturbance of bald eagles or
their habitat. Under federal law a permit may still be required for activities that impact bald eagles or their
