OPERATION AND MAINTENANCE MANUAL

Estep/Hebert LLC
SEPA NO. SEP 07-0004
FAC NO. FAC 14-0003
GRA NO. GRA 13-0024
Site Address:
The project is located in SW 1/4 31-22N-05 East, W.M.,NEC -Auburn Way North
and D'Street N.E. The tax parcel no. is 936060-0160.
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 Esteo/Hebert LLC Auburn North project located at 4800 Auburn Way
North. The site has an area of approximately 0.76 acres and is currently graded
with a wet/detention vault constructed. The subject site will be developed as a
multi-tenant commercial building.
The subject site will have a 0.21 acre building with asphalt parking lot, surrounding
landscaping, pipe conveyance all draining to the existing wet/detention vault.
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 wet/detention vault
located in the south corner of the parcel. Here the storm water will be released into
a 12-inch conveyance pipe in the north curb line of'D'Street N.E.
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/wet pond,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
No. 3 -Closed Detention Systems (tanks/vaults)
No. 4 —Control Structure/Flow Restrictor
No. 5—Catch Basins
No. 12—Wet Vaults
(Department of Ecology Storm Water Manual, August 2001).
Treatment BMP'S
A wet/detention vault has been installed to treat runoff for conventional pollutants.
The wet vault 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 Utilities 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 Utilities Sections.
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 weUdetention vault 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.
