Site Address:
The project is located in the Southeast quarter of the Northeast quarter of
Section 13, Township 21 North, Range 4 East, W.M., One East Main
Street. The tax parcel numbers are 781620-0005, 781620-0015, 781620-
0020, 781620-0025, 781620-0035, 781620-0030, 049200-0595, and
049200-0605.
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 Professional Plaza located at One
East Main Street. The site has an area of approximately 0.97 acre and is
currently developed with six existing structures, with associated sidewalks
and utilities. The subject site will be developed as a 90,000 square foot
three-story mixed-use/professional office building with some retail.
The subject site will include pavement, landscaping, buildings, and
walkways.
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 a
storm water 2-cartridge stormfilter unit located at the southeast corner of
the site. Here the storm water will be released into an 8-inch proposed
storm drainage line running to the south connecting into the existing 12-
inch public storm main in the north curbline of East Main Street.
Storm Water Easement and Maintenance Agreement
Page 8 of 17
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 and
stormfilter 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)
No. 5 - Catch Basins
No. 15 - StormfilterTM (leaf compost filter)
No. 16 - Baffle Oil/Water Separators (API Type)
No. 17 - Coalescing Plate Oil/Water Separators
No. 18 - Catch Basin Inserts
Treatment BMP'S:
A 2-cartridge catch basin stormfilter has been installed to treat runoff for
conventional pollutants. The stormfilter was designed to treat 64% of the 2-
year storm event (water quality storm) for water quality treatment.
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.
Storm Water Easement and Maintenance Agreement
Page 9 of 17
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 stormfilter 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.
