STORMWATER POLLUTION PREVENTION PLAN
for
VALLEY PONTIAC-BUICK-GMC
SEPA # SEP 99-0031
FAC # GRA 02-0003
Site Address:
The project is located in Section 6, Township 21 North, Range 5 East,
W.M. on the northeast corner if Auburn Way North and 30th Street NE.
The Tax Parcel # 000400-0027
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 Valley Pontiac building located at the
northeast corner of 30th Street NE and Auburn Way North. The site has
an area of approximately 1.11 acres and is currently undeveloped except
for existing curb, gutter, and sidewalk. The subject site will propose
an automotive sales building with landscaping and asphalt parking.
The subject site is mostly flat with a small gradient from the perimeter
towards the center of the site. The storm water runoff collected on-
site is absorbed into the existing soils and sheet flows and collects in
a depression in the center of the site. Here the storm water will
slightly pond in the wet months until runoff is absorbed into the ground
or evaporates into the air. There is no evidence of any concentrated
on-site flows. There is also no evidence of any erosion, or off-site
flows from storm water runoff coming on-site. The existing site has no
storm water quantity or quality control of any kind.
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 detention/wet pond located at the rear of the
site. Here the storm water will be released into a 12" proposed storm
drainage line running to the south connecting into the existing 12"
storm main in the north curb line of 30th Street NE. This system flows
directly into the public system located in Auburn Way North.
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 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. 1 - Detention Pond
No. 4 - Control Structure/Flow Restrictor
No. 5 - Catch Basins
No. 11 - Wet Pond
(Department of Ecology Storm Water Manual, August 2001).
Treatment BMP'S
A two celled detention / wet pond has been installed to treat runoff for
conventional pollutants. The wet pond 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 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 14
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 detention / wet pond
must be properly maintained. Be careful to avoid introducing landscape
fertilizer to receiving waters or groundwater. If wet pond side slopes
become eroded over 2 inches 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 arc inlcndcd to he
conditions for determining if maintenance actions are required as identified lhroul;h
inspection. They are not intended to be measures of the facility's required condition at all
times between inspections. In other words, excecdence of these conditions at any lime
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 it facility is in
a condition that requires a maintenance action.
