STORMWATER POLLUTION PREVENTION PLAN
For the
PIKE STREET DEVELOPMENT
SEPA# 98-0012
FAC# 05-0019
Site Address: 1731 PIKE STREET NW, AUBURN, WA
The project is located in NE 1/4, Section 11, Township 21 North, Range 4 East,
W.M. at 1731 Pike Street NW. The Tax Parcel # 030351-0170
Introduction:
This stormwater pollution prevention plan has been prepared to address the City
of Auburn's site development and storm drainage requirements for the proposed
Pike Street Development located at 1731 Pike Street NW. The site has an area
of approximately 1.987 acres and is currently vacant. The subject site will have
two commercial buildings constructed along with a storm water detention pipe
and an Aqua -Swirl AS-3 concentrator for water quality treatment. Existing
utilities are located on or near the site and do not require any major extensions
and only minor work in the R.O.W. Access will be from Pike Street NW.
The subject site is vacant, and will be fully developed with two commercial
buildings and paved parking stalls and associated driveways. The proposed
development is not expected to generate any pollution. A 49" x33" CMP Arch
Pipe tank system will provide underground storm water detention and a Model
AS-3 Aqua-Swirl Concentrator will provide water quality control for storm runoff
from the site.
According to the City of Auburn's Construction Standards for storm water
management, the city requires storm water quantity and quality control
to all proposed developments. We have proposed to collect all of the
storm water runoff from the landscaped, building and pavement areas in a
series of catch basins. This water will be conveyed by storm drainage
pipe to the storm drainage detention pipe located under the driveway and
then to the Aqua-Swirl. The water will then be released through a 12"
pipe connected to the existing SDMH K3F in Pike Street NW. Should
overflow occur the water would flow over the paved driveway and enter
the existing storm drainage system in Pike Street NW.

Plan Goal
The specific purpose for the storm water facility is to minimize pollution that is
typically associated with modern development. In general, pollution from motor
vehicles and pollution generated from erosion. Attached to this narrative is a
maintenance manual, which offers guidelines to the owner for storm water facility
maintenance.
Prevention BMP'S
The catch basins shall have stenciled on them "DUMP NO WASTE - DRAINS
TO GROUND. The owner shall be responsible for sweeping the lot, installing
storm drainage stenciling and provide spill control procedures. In case of spill
call DOE at 1-425-649-7000. The catch basins, detention storage pipes, and
Aqua-Swirl will be visually inspected for accumulation of debris and silt and will
be maintained as required by this pollution prevention plan and attachments.
Maintenance Standards for Drainage Facilities
No. 3 - Closed Detention Systems
No. 4 - Control Structure/Flow Restrictor
No. 5 - Catch Basins
(Department of Ecology Storm Water Manual, August 2001).
Treatment BMP'S
An Aqua-Swirl AS-3 has been installed to treat runoff for conventional pollutants.
The Aqua-Swirl was designed to treat 1.8cfs. In actuality the Aqua-Swirl will treat
100% of the 25 year storm peak flow of 0.9cfs and provide over 80%TSS
removal. . In addition, the detention tank was designed to detain the volume
created from releasing half the existing 2-year, 10, 25, and 100-year storm
events, while holding the developed 2-year, 10, 25, and 100-year storm volumes.
The City of Auburn Utilities Section is to review and approve any changes to this
stormwater Pollution Prevention Plan prior to changes in its implementation.
Additionally, any changes in ownership or person of responsibility are to be
reported to the City Utilities Sections.
Storm Water Easement and Maintenance Agreement
Page 7 of 18
Inspection / Maintenance:
Regular inspections of the drainage facilities should be carried out twice per
year, in the spring and fall. The responsible party should keep records of these
inspections available for review by the City. Additional inspections may be
required after severe seasonal storms.
Routine maintenance of the site will include mowing, care of landscaping and the
removal of trash and debris from the drainage system. The parking lots and
driveways should be kept clean and in repair. Events such as major storms or
heavy winds will require immediate inspections for damages.
To ensure proper water quality and treatment, the stormwater detention tank,
catch basins, pipes and Aqua-Swirl must be properly maintained. Be careful to
avoid introducing landscape fertilizer to receiving waters or groundwater.
Catch Basins shall be cleaned when sump is 1/3' full of sediment or debris.

Maintenance Standards for Drainage Facilities
The facility-specific maintenance standards contained in this
section are intended to be conditions for determining if
maintenance actions are required as identified through
inspection. They are not intended to be measures of the
facility's required condition at all times between inspections.
In other words, exceeding these conditions at any time
between inspections and/or maintenance does not
automatically constitute a violation of these standards.
However, based upon inspection observations, the inspection
and maintenance schedules shall be adjusted to minimize the
length of time that a facility is in a condition that requires a
maintenance action.

0 Inspection
All AquaShield T" products can be inspected from the surface, eliminating the
need to enter the systems to determine when cleanout should be performed.
In most cases, AquaShield"", Inc. recommends a quarterly inspection of the
Stormwater Treatment Systems for the first year of operation so an appropriate
schedule of maintenance can be developed.
Based upon experience from the system's first year in operation, we recommend
the inspection schedule be revised to reflect the site-specific conditions
encountered. Typically the inspection schedule for subsequent years is reduced
to semi-annual inspection.
IN Aqua-Swir1T"' Maintenance
The Aqua-Swirl'" has been designed to minimize and simplify the inspection and
maintenance process. The system can be inspected and maintained completely
from the surface, thereby eliminating the need for confined space entry.
Furthermore, the entire structure (specifically, the floor) is accessible for visual
inspection from the surface. There are no areas of the structure that are blocked
from visual inspection or periodic cleaning.
Inspection of any free-floating oil and floatable debris can be directly observed
and maintained through the manhole access provided directly over the swirl
chamber.
Aqua-Swirl"" Inspection Procedure
To inspect the Aqua-SwirlT", a hook is needed to remove
the manhole cover. AquaShield`" provides a customized
manhole cover with our logo to make it easy for
maintenance crews to locate the system in the field. We
also provide a permanent metal information plate attached
inside the access riser, which provides our contact
information, the Aqua-Swirl" model size, and serial
number.
Storm Water Easement and Maintenance Agreement
Page 15 of 18
e Inn a w"dia rod
,r
The only tools required to inspect the Aqua-Swirl'"' system are a flashlight and a
measuring device (i.e. stadia rod) or pole. Because of the tremendous access
provided, floating oil and debris can be observed
directly from the surface. Sediment depths can
easily be determined by lowering a measuring
device to the top of the sediment pile and to the
water's surface. When the sediment pile is within
30" to 36" of the water surface the system should
be maintained.
It should be noted that in order to avoid
underestimating the volume of sediment in the
chamber, the measuring device must be carefully
lowered to the top of the sediment pile. The finer
sediment at the top of the pile, typically offers less
resistance to the measuring device than the larger
particles.
Aqua-Swirl" Cleanout Procedure
Clean out of the Aqua-Swirl'`" is simple. Free-floating oil
and floatable debris can be observed and removed directly
through the 30° service access provided.
A vacuum truck can be used to remove the accumulated
sediment and debris. It is important to note that the
entire sediment storage area can be reached with a
vacuum hose from the surface (reaching all the sides).
Disposal of the material is typically treated in the same tr..b, k k tta
fashion as catch basin cleanouts. AquaShield'" A4u&-s rr concentr~
recommends that all materials removed be handled and
disposed of in accordance with local and state requirements.
An "Inspection and Maintenance Manual" is provided with each Aqua-Swirl"`
system for more detailed maintenance procedures. On the following page, you
will find sample Inspection Data Sheets.
