STORM WATER POLLUTION PREVENTION
MAINTENANCE and OPEATION SCHEDULE
for the
AUBURN NORTH DISTRIBUTION CENTER
FAC05-0016
Site Address:
The project is located at 4510 Frontage Road NW, in a portion of:
Section 36,Township 22N- Range 04 East, W.M..
The tax parcel number is 362204-9020.
Introduction:
This storm drainage technical information report has been prepared to
address the City of Auburn's site development and storm drainage
requirements for the proposed Auburn North Distribution Center located
at 4510 Frontage Road. The site has an area of approximately 21.1 acres
and is currently undeveloped. The subject site will be developed as large
office warehouse with dock high loading.
The subject site will contain a 410,000 square-foot warehouse and
associated dock high loading, parking, drive aisles, landscaping, storm
water conveyance system with detention, and a water quality facility.
According to the City of Auburn's Construction Standards for storm water
management, the city requires storm water quantity and quality control to ail
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 a
storm water detention and water quality facility located directly south of the
warehouse building. Here the storm water will be released into a
24" storm drainage line running to the west and south connecting into
30" drainage line whose outlet is adjacent to an existing culvert under
Frontage road. The culvert discharges water from our facility and the
existing wetland to the south into the main stem of Mill creek.
Storm Water Easement and. Maintenance Agreement
Page 7 of 18
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 STREAM." 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/wetpond, and control structures 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 (from the Department of
Ecology Storm Water Manual, August 2001)
(Add numbered standards)
No. 1 - Detention Pond
No. 4 - Control Structure/Flow Restrictor
No. 5 - Catch Basins
No. 6 - Debris Barrier (Trash Racks)
No. 11 - Wetpond
Treatment BMP'S:
A two-celled detention/wetpond has been installed to treat runoff for
conventional pollutants. The wetpond was designed to treat 64% of the 2-
year storm event (water quality storm) for water quality treatment. In
addition, the detention pond 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 Storm Drainage Utility section is to review and approve
any changes to this Storm Water 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 of Auburn Storm Drainage Utility
section.

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 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 detention/wetpond
must be properly maintained. Be careful to avoid introducing landscape
fertilizer to receiving waters or groundwater. If wetpond side slopes
become eroded over 2" deep, stabilize by using appropriate erosion control
measures (e.g., rock reinforcement, planting of grass, compaction).
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 facilities 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.
