Cooke Short Plat
Private On -site Stormwater Control Facilities
Operation and Maintenance (O&M) Manual
This Private On -site Stormwater Control Facilities Operations and Maintenance Manual
Manual) is being recorded by the Owner at the request of the City of East Wenatchee.
Section 1 Purpose
The Cooke Short Plat contains a private on -site stormwater drainage facility designed to
control runoff originating from the impervious surfaces constructed with the main private
driveway and the fire truck turnaround. Inadequate maintenance or improper operation
is a common cause of failure for stormwater facilities. This plan provides operation and
maintenance guidelines for the onsite storm water drainage facilities located in the
Cooke Short Plat. The Homeowners shall operate and maintain the facility in
accordance with this Operation and Maintenance (O&M) plan that is prepared in
accordance with the provisions in the most current Department of Ecology's "Eastern
Washington's Storm Water Manual" and the East Wenatchee Municipal Code.
The Stormwater Drainage Report and Plan for this development was prepared by Ed
Zontek, P.E., a copy of which is on file with East Wenatchee Community Development
Department. The date of the final approved Stormwater Drainage Report document is
May 2014. There are also as -built plans on file with the city that are dated 8-15-2014.
This document provides only the operation and maintenance requirements for the
stormwater system designed and constructed to accommodate the stormwater runoff
from the private driveway and fire truck turnaround that serves lots within this short plat.
Individual on -site systems are required for all lots at the time a building permit
application is submitted to the City. No discharge to Sand Canyon or to the existing
stormwater system will be permitted from the individual lot improvements.
It shall be the responsibility of the lot owners and/or their successors to hereafter
maintain the private stormwater drainage system in the originally designed condition.
The costs associated with maintenance and operation functions for this stormwater
system will be the responsibility of the property owners. The schedule of maintenance
activities contained in this Manual must be implemented to ensure that the stormwater
facilities are adequately maintained and properly operated to ensure that they function
as designed and constructed in accordance with the design plan and the requirements
of the East Wenatchee Municipal Code.
Section 2 General Operational Characteristics
The drainage facilities for the Cooke Short Plat are generally very simple and have low
maintenance requirements. A periodic visual inspection of the facilities will identify any
required maintenance. Most maintenance will consist of keeping the ditches and catch
basins free of deleterious debris and sediment and keeping the vegetation in the swale
alive and healthy with periodic mowing. However, a specific inspection schedule must
be followed to ensure proper and safe operating conditions. See Section 4 for
recommended maintenance schedules.

The stormwater drainage system discharges the stormwater into roadside ditches,
where excess stormwater is conveyed to a series of catch basins (Catch Basins #2-6),
storm drain pipes, and culverts that ultimately channel the stormwater to a bubble -up
structure (Catch Basin #1) where the private driveway intersects with Briarwood Drive.
The stormwater then flows down the gutter along the east side of the street and into an
existing detention pond (Infiltration Basin #6).
Additionally, off -site stormwater enters the property from the east and is intercepted in a
swale that runs along the east boundary of Lot #1 and Lot #2 from the top of ridge to a
rock armored inlet before entering Catch Basin #7. The swale is approximately 268 feet
in length. The stormwater is then conveyed through an 8" pipe to a rockery headwall
inlet structure, adjacent to the driveway, that will infiltrate the runoff and drain it into a
36" culvert that discharges to a rock armored overflow spillway in Sand Canyon north of
the lower portion of the access driveway on Lot 2.
It is importanct to provide adequate operation and maintenance activities to ensure that
the swale, ditches, catch basins, and culverts remain silt or dirt free. Should these
facilities fill up or become clogged, the only remedy would be to remove the silt and
debris. Periodic maintenance is very important to ensure that costly, major repairs can
be avoided. Cleaning the whole system at intervals is the most effective approach.
Components of the stormwater control facility that have been damaged, or are noted as
not functioning properly, shall be repaired in a timely manner. The size, placement, and
materials used for any part of the stormwater control facility shall not be altered without
written approval from the City. Excerpts from the engineering drawings that relate to the
stormwater system are included with this Manual as Appendix A. Full-sized drawings
are available for review at the East Wenatchee Public Works Department.
Section 3 Maintenance Log:
A log of maintenance activity documenting inspections and actions taken must be kept
by the homeowners and be available for inspection by the City of East Wenatchee. A
Maintenance Log template is included with this Manual as Appendix B.
Section 4 Maintenance Criteria and Schedule:
The effectiveness of post -construction stormwater control best management practices
BMPs) depends upon regular inspections of the control measures. BMPs are a series
of actions that are intended to reduce stormwater pollution, prevent the discharge of
contaminants to natural water bodies, and reduce stormwater facility maintenance
costs.
Routine maintenance is performed regularly to maintain both the ascetics of the BMPs
and their good working order. Routine inspection and maintenance helps prevent
potential nuisances (odors, mosquitoes, weeds, etc.), reduces the need for repair
maintenance, and reduces the chance of polluting stormwater runoff by finding and
fixing problems before the next rain. The failure of structural stormwater BMPs can lead
to downstream flooding, which can cause on -site and off -site property damage.
1) Interception Swale — Located along the east property line of Lot 1 and Lot 2.
The interception swale is 1 foot in depth with 3H:1 V slopes. The swale is vegetated
with native and non-native grasses according to the planting mixture on Sheet C-2 of

the plans. That planting prescription is also included in this manual. Perpetual
maintenance of the interception swale, including replacement and/or reconstruction
of the swale is needed to maintain the design function.
a) Inspection interval: This swale must be inspected and maintained at 6-month
intervals. Recommended inspection dates are April 1 and September 1.
Inspections in spring will identify conditions resulting for winter use and ensure
facilities are prepared for summer use. Inspection in fall will identify conditions
resulting from summer use and ensure facilities are prepared for winter use.
Additionally, the swale should be inspected after a major storm event.
b) Maintenance Requirements: The table below identifies potential problems and
provides recommended maintenance actions.

permanent grass seed mixture shall be seeded, fertilized and mulched in compliance with the requirements of Section8-023(16)
of the current edition of the WSDOT Standard Specifications.
2) Drainage Ditches — The major conveyance feature for this stormwater system is a
series of rock armored roadside ditches adjacent to the driveway. These ditches
convey the stormwater to several catch basins. Common road debris, including
eroded soil, oils, vegetative particles, and heavy metals, can be a source of
stormwater pollutants
a) Inspection interval: Roadside ditches must be inspected and maintained at 6-
month intervals. Recommended inspection dates are April 1 and September 1.
Inspections in spring will identify conditions resulting for winter use and ensure
facilities are prepared for summer use. Inspection in fall will identify conditions
resulting from summer use and ensure facilities are prepared for winter use.
Additionally, the ditches should be inspected after a major storm event.
b) Maintenance Requirements: Maintenance practices should provide for erosion
and sediment control and ensure that the ditches are kept free of rubbish and
debris.
i) Any trash, vegetation growth, debris or sediment that obstructs or has the
potential of obstructing the flow of stormwater in the drainage ditches must be
removed. Maintenance is necessary whenever accumulated sediment or
debris exceeds 20% of the design depth.
ii) If erosion of the sidewalls or channel bottom is observed, stabilize the soil and
add or redistribute rocks as needed to ensure a clean, continuous gravel
surface to prevent further erosion. Native soil should not be visible in the
channel.
iii) Material removed during ditch cleanings shall not to be left on the roadway
surfaces. Sweep dirt and debris remaining on the pavement at the completion

of ditch cleaning operations. Roadside ditch cleanings, not contaminated by
spills or other releases, may be screened to remove litter and separated into
soil and vegetative matter (leaves, grass, needles, branches, etc.). The soil
may be handled as `clean soils' and the vegetative matter can be composted
or disposed of in a municipal waste landfill. Roadside ditch cleanings
contaminated by spills or other releases known, or suspected, to contain
dangerous waste must be handled following the Dangerous Waste
Regulations (Chapter 173-303 WAC), unless testing determines it is not
dangerous waste.
3) Culvert Pipes:
a) Inspection interval: Culvert pipes must be inspected and maintained at 6-
month intervals. Recommended inspection dates are April 1 and September 1.
Inspections in spring will identify conditions resulting for winter use and ensure
facilities are prepared for summer use. Inspection in fall will identify conditions
resulting from summer use and ensure facilities are prepared for winter use.
Additionally, the culverts should be inspected after a major storm event.
b) Maintenance Requirements:
i) Any trash, debris or sediment that obstructs or has the potential of
obstructing the culvert pipes must be removed by vactor or flushing.
Maintenance is necessary whenever accumulated sediment or debris
exceeds 20% of the design depth.
ii) Examine culvert for scour or sedimentation at the inlet and outlet and any
debris in the pipe. Any scour or sedimentation at the inlet and outlet sections
must be repaired to its design condition. Any materials obstructing the inlet or
outlet section must be removed.
iii) Examine culvert pipe for rust, deterioration. Maintenance is required when
more than 50% of the pipe is showing rust or deterioration. Any dents that
decreases the cross section are of the pipe by more than 20% or puncture is
evident that impacts the performance of the pipe.
iv) Material removed during culvert cleanings shall not to be left on the roadway
surfaces. Sweep dirt and debris remaining on the pavement at the completion
of culvert cleaning operations. Materials that are not contaminated by spills or
other releases, may be screened to remove litter and separated into soil and

5) Driveway Sweeping:
It is recommended that the private driveway be professionally cleaned on an annual
basis to reduce the potential for sediment entering the stormwater system.
6) Long Term Funding:
A provision has been included in section 3 of the Private Access Maintenance &
Improvement Agreement for long-term funding for the stormwater system and the fire
suppression system. That provision requires that each lot Owner pay $200.00 per year
to a fund for the purpose of repairing elements of the "common area" stormwater and
fire suppression systems. The Developer has established an account at Cashmere
Valley Bank- account # 1000463594. Each lot owner will be a joint signer on the
account. The annual payment is due each year by March 15th. The fund is not intended
to be used for regular and ordinary maintenance. This is a reserve account for major
repairs or replacement of components of the stormwater or fire suppression systems.
The cost for the maintenance and repairs, at the intervals noted in the O & M Plan, shall
be the responsibility of the individual owners in common. All expenses shall be shared
equally between the three lots within this short plat.
