Site Address:
The project is located in the South 1/2 - Section 32 - Township 21 N -
Range 5 East, W.M., located at the NW corner intersection of Kersey Way
S.E. and 49th Street S.E. The tax parcel number is 322105-9027.
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 Litowitz Property Sewer Extension located at
the NW corner intersection of Kersey Way S.E. and 49th Street S.E. The
site has an area of approximately 37.7 acres and is currently undeveloped.
The subject site will be developed to contain a sewer extension in the
Southeast corner of said property (approx. 2.91 acres). The sewer
extension will be partially constructed on an existing gravel road located in
the NE corner of tax parcel 322105-9010.
Tax Parcel 322105-9027 will be developed to contain the sewer extension
main, one sewer manhole, maintenance access road, one storm drainage
control structure, and detention pond. Tax Parcel 322105-9010 will be
developed to contain part of the sewer extension main and two manholes.
Both parcels contain a stream/wetland buffer which will be slightly impacted
and restored.
Storm Water Easement and Maintenance Agreement
Page 9 of 18
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 gravel access road, existing undisturbed forest, and
Kersey Way S.E. through existing flow channels and designed road cross
slopes. This water will be conveyed over land to a storm water detention
facility located in the city of Auburn, Washington. Here the storm water will
be released from control structure and discharged at a controlled rate to the
existing forest and wetland located directly to the west of the access road.
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, detention/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 (from the Department of
Ecology Storm Water Manual, August 2001)
No. 1 - Detention Pond
No. 4 - Control Structure/Flow Restrictor
No. 6 - Debris Barriers
No. 7 - Energy Dissipaters
Storm Water Easement and Maintenance Agreement
Page 10 of 18
Inspection/Ma1 ntenance:
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 the removal of trash and debris
from the drainage system. Events such as major storms or heavy winds
will require immediate inspections for damages. If pond side slopes
become eroded over 2" deep, stabilize by using appropriate erosion control
measures (e.g., rock reinforcement, planting of grass, compaction).
The control structure shall be cleaned when sump is 1/3' full of sediment or
debris.

Plan and/or Information Updates:

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 Storm Drainage Utility section.

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.
