Site Address:
The project is located in NW 114 Section 16 Township 21 North, Range 5
East, W.M., 12401 SE 320th Street, Auburn, WA 98092. The tax parcel
number is 162105 -9008.
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 Facility Building project located at 12401 SE
320th Street, Auburn, WA 98092. The site has an area of approximately
0 3 acres and is currently undeveloped with some areas of existing
pavement. The subject site is situated between two existing building on the
campus. The subject site will be developed to accommodate the
community college facilities department.
The subject site will be composed of a new building surrounded by a new
access driveway and paved parking area. A 5 -foot wide paved walkway will
be constructed.
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. Roof runoff will be conveyed by storm drainage pipe to two
50 -foot long dispersion trenches located within the forested area south of
the new facilities building.
Storm Water Easement and Maintenance Agreement
Page 7 of 13
Here the storm water will be dispersed downstream through the existing
vegetation for more than 50 feet. Runoff eventually reaches the Green
River Pavement runoff is filtered through the permeable pavement to the
underlying soil or conveyed to the existing storm system that discharges to
an existing detention vault.
Flow control and water quality are not required for this project because the
developed peak discharges are below the threshold requirements.
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 City of Auburn
Surface Water Storm Manual, November 2009)
No. 5 — Catch Basins
No. 24 — Pervious Pavements
Treatment BMP'S:
Water quality treatment is not required for this project because the majority
of the new impervious area is non - pollution generating surface. The
majority of the runoff will be filtered through the existing underlying soil
layer
Storm Water Easement and Maintenance Agreement
Page 8 of 13
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 filtration of runoff into the underlying soil layer, the
dispersion trenches and permeable pavers 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 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.
