Responsibility
The facility is to be maintained by the property owner. The pre parer has designed a system that can be easily
maintained by the maintenance staff.
A copy of the Operations and Maintenance (O&M) Plan shall be provided to all property owners and property
managers.
Descriptions
The Stormwater System collects and treats runoff from pollution -generating surfaces within the site as
required by the City of Springfield.
All runoff from the impervious surfaces at the EC Cares Springfield site will be treated by a rain garden and
filter strip and infiltrated using a soakage trench.
Definitions
• Filter Strips are gently sloped vegetated or grassed areas that stormwater runoff is directed to flow
over and filter through.
• Rain Gardens are vegetated, flat-bottomed, shallow landscape depressions used to collect and hold
stormwater runoff.
• Soakage Trenches are flood control devices injecting stormwater runoff into the ground recharging
groundwater.
• Growing Media is specialty soil containing little to no fines designed to filter stormwater reliably
without clogging. In the event that the planter soil needs to be replaced, it must be replaced with soil
that matches the building's plans and specifications.
• Overflow Inlets are vertical pipes with atrium grates over them. They allow stormwater from large
rain events to bypass treatment and enter the downstream storm system. The grates prevent debris
and rodents from entering the piped storm system. The domed nature of the grates discourages
clogging at the inlet.
Schedule
The whole system shall be inspected and maintained annually and within 48 hours after each major storm
event. This O&M plan defines a major storm event as 2 inches of rain in 24 hours or more. All components of
the storm system as described on the following page must be inspected and maintained frequently, or they
will cease to function effectively. The facility owner must keep a log recording all inspection dates,
observations and maintenance activities. Receipts shall be saved when maintenance is performed so there is
a record of expenses.

Vegetated Filter Strips
Operations and Maintenance Plan
Vegetated Filter Strips are gently sloped vegetated areas that stormwater runoff is directed to flow and
filter through. Stormwater enters the filter as sheet flow from an impervious surface or is converted to
sheet flow using a flow spreader. Flow control is achieved using the relatively large surface area and
check dams. Pollutants are removed through infiltration and sedimentation. The vegetative filter should
drain within 48 hews of storm event. All facility components and vegetation shall be inspected for proper
operations and structural stability. These inspections shall occur, at a minimum, quarterly for the first 2
years from the date of installation, 2 times per year thereafter, and within 48 hours after each major storm
event. The facility owner must keep a log, recording all inspection dates, observations, and maintenance
activities. The following items shall be inspected and maintained as stated:
Flow Spreader shall allow runoff to enter the vegetative filter as predominantly sheet flow.
• Source of erosion damage shall be identified and controlled when native soil is exposed or erosion
channels are forming.
• Sediment build-up new or exceeding 2 inch in depth shall be removed.
Filter Inlet shall assure unrestricted stormwater flow to the vegetative filter.
• Sources of erosion shall be identified and controlled when native soil is exposed or erosion channels
we present.
• Sediment accumulation shall be hand -removed with minimum damage to vegetation using proper
erosion control measures. Sediment shall be removed if it is more than 2 inches thick or so thick as to
damage or kill vegetation.
• Inlet shall be cleared when conveyance capacity is plugged.
• Rocks lash pads shall be replenished to prevent erosion.
Filter Media shall allow stortnwater to percolate uniformly through the vegetative filter.
• If the vegetative filter does not drain within 48 hours, it shall be re -graded and replanted according to
design specifications. Established trees shall not be removed or harmed in this process.
• Debris in quantities more than 2 inch deep or sufficient to inhibit operation shall be removed
routinely e.., no less than quarterly), or upon discovery.
Check Dams and Dissipaters shall direct and control flow.
• Causes for altered water flow and channelization shall be identified, and obstructions cleared upon
discovery.
• Cracks, rot, and structural damage shall be repaired.
Filter Outlet shall allow water to exit the vegetative filter as sheet flow, unless a collection drainpipe is
used.
• Sources of erosion damage shall be identified and controlled when native soil is exposed or erosion
channels are deeper than 2 inches.
• Outlet shall be cleared when 50% of the conveyance capacity is plugged. Sources of sediment and
debris shall be identified and corrected.
Vegetation shall be healthy and dense enough to provide filtering while protecting underlying soils from
erosion.
• Fallen leaves and debris from deciduous plant foliage shall be raked and removed if build up is
damaging vegetation.
• Nuisance and prohibited vegetation (such as blackberries and English Ivy) shall be removed when
discovered. Invasive vegetation contributing up to 25% of vegetation of all species shall be removed
and replaced.
• Dead vegetation shall be removed to maintain less than 10% of area coverage or when vegetative
filter fimction is impaired. Vegetation shall be replaced immediately to control erosion where soils
are exposed and within 3 months to maintain cover density.
Debris and Litter shall
be removed to ensue stormwater conveyance and to prevent clogging of inlet
Appendix 3A-4 Page 11 of 31 EDSP Adopted December 03, 2012
and outlet drains and interference with plant growth.
Spill Prevention measures shall be exercised when handling substances that contaminate stony water.
Releases of pollutants shall be contacted as soon as identified.
Training and/or written guidance information for operating and maintaining vegetated filters shall be
provided to all property owners and tenants. A copy of the O&M Plan shall be provided to all property
owners and tenants.
Access to the vegetative filter shall be safe and efficient. Egress and ingress routes shall be maintained to
design standards. Obstacles preventing maintenance personnel and/or equipment access to the facility
shall be removed. Gravel or ground cover shall be added if erosion occurs, e.g., due to vehicular or
pedestrian traffic.
Insects and Rodents shall not be harbored in the vegetated filter. Pest control measures shall be taken
when insects/rodents are found to be present.
• If a complaint is received or an inspection reveals that a stormwater facility is significantly infested
with mosquitoes or other vectors, the property owner/owners or their designee may be required to
eliminate the infestation at the City inspector's discretion. Control of the infestation shall be
attempted by using first non -chemical methods and secondly, only those chemical methods
specifically approved by the City's inspector. Acceptable methods include but are not limited to the
following:
I. Installation of predacious bird or bat nesting boxes.
ii. Alterations of pond water levels approximately every four days in order to disrupt mosquito larval
development cycles.
iii. Stocking ponds and other permanent water facilities with fish or other predatory species.
iv. If non -chemical methods have proved unsuccessful, contact the City inspector prior to use of
chemical methods such as the mosquito larvicides Bacillus thurengensis var. israeliensis or other
approved larvicides. These materials may only be used with City inspector approval if evidence
can be provided that these materials will not migrate off-site or enter the public stormwater
system. Chemical larvicides shall be applied by a licensed individual or contractor.
• Holes in the ground located in and around the vegetated filter shall be filled.

Soakage Trenches
-
Operations and Maintenance Plan
Soakage Trenches consist of drain rock and sand, and receive stormwater from roof downspouts and/or
area drains. There are various components within the system—piping, silt basin and the trench itself.
The Conveyance Piping consists of an inlet pipe (downspout or area drain), an outlet pipe located
between the silt basin and the soakage trench, and a perforated pipe, located on top of the aggregate bed
of the soakage trench. The Silt Basin is a structure receiving runoff from an inlet pipe and conveying it
to the soakage trench. The silt basin serves as the pre-treatment system for the soakage trench, removing
sediments and other debris that can impact its proper functioning. All facility components, vegetation,
and source controls shall be inspected for proper operations and structural stability. These inspections
shall occur, at a minimum, quarterly for the first two years from the date of installation, than two times
per year afterwards, or within 48 hours after each major storm. The facility owner must keep a log,
recording all inspection dates, observations, and maintenance activities. The following items shall be
inspected and maintained as stated:
Soakage trench infiltration: If water is noticed on top of the trench within 48 hours of a major storm, the
soakage trench may be clogged.
• Check for debris/sediment accumulation, rake and remove and evaluate upland causes (erosion,
surface or roof debris, etc.
• Assess the condition of the aggregate and the filter fabric in the trench. If there is sediment in the
aggregate, excavate and replace.
• If there is a tear in the filter fabric, repair or replace.
• The soakage trench area shall be protected from compaction timing construction.
Conveyance Piping: If water ponds over the trench for more than 48 hours after a major storm and no
other cause if identified, it may be necessary to remove the filter fabric to determine if the perforated pipe
is clogged with sediment or debris.
• Any debris or algae growth located on top of the soakage trench should be removed and disposed of
properly.
• If the piping has settled more than 1 -inch, add fill material. If there are cracks or releases, replace or
repair the pipe. If there are signs of erosion around the pipe, this may be an indication of water
seeping due to a crack or break.
Silt Basin: If water remains in the soakage trench for 36-48 hours after storm, check for sediment
accumulation in the silt basin
• If less than 50% capacity remains in the basin or 6 of sediment has accumulated, remove and dispose
the sediment.
Spill Prevention: Virmally all sites, including residential and commercial, present dangers from spills.
All homes contain a wide variety of toxic materials including gasoline for lawn mowers, antifreeze for
cars, nail polish remover, pesticides, and cleaning aids that can adversely affect groundwater if spilled. It
is important to exercise caution when handling substances that can contaminate stormwater.
• Activities that pose the chance of hazardous materials ills shall not take place new soakage trenches.
A Shut -Off Valve or Flow -Blocking Mechanism may have been required with the construction of the
soakage trench to temporarily prevent stormwater from flowing into it, in the event of an accidental
material spill. This may also involve mats kept on-site that can be used to cover inlet drains in parking
lots. The shut-off valve shall remain in good working order, or if mats or other flow -blocking
mechanisms are used, they shall be kept in stock on-site.
Training and/or written guidance information for operating and maintaining soakage trenches shall be
provided to all property owners and tenants. A copy of the O&M Plan shall be provided to all property
owners and tenants.
Access to the soakage trench is required for efficient maintenance. Egress and ingress routes will be
maintained to design standards at inspections.
Appendix 3A-4 Page 19 of 31 EDSP Adopted December 03 2012
Insects and Rodents shall not be harbored in the soakage trench. Pest control measures shall betaken
