Maintenance Responsibility
With the project site being in the City of Corona limits, P OA will have ongoing maintenance responsibilities. Site design and treatment BMPs have been designed to keep maintenance efforts in line with Main Street Metro project maintenance activities.
POA Maintenance Responsibilities: Infiltration Trenches and Grass Swale /Depressed Landscape maintenance of common areas and landscape areas within the project.
General Operation and Maintenance Activities
Operation and maintenance (O&M) activities are descr ibed below. The categories of O&M activities are "routine" and "major" where routine refer to activity conducted on a regular schedule, whereas major refers to infrequent activities triggered mainly by need. Each category and its respective activities are described in the following sections.
Routine Operation and Maintenance Activities
O&M responsibility, initially by Developer/Builder until the establishment of POA. O&M, normally performed by POA maintenance crews as part of normal/scheduled maintenance activities.
Site Inspection
The storm drain inlets will be inspected on a regular, scheduled basis to ensure that the facility is operating properly, to record observations, and to initiate any actions that may be required. While the frequency of site inspections may vary depending on the season, it will typically be on a monthly basis.
Trash & Debris Removal
Litter may be picked up at any time during site visits for other purposes. Regular, scheduled trash/debris removal will be performed at all sites on a quarterly basis and/or after storm events that result in heavy trash accumulations.
Minor Vegetation Removal/Thinning
Vegetation growth will be inspected annually, and removed or thinned as necessary. Vegetation at inlets and outlets will be manually or mechanically removed if vegetation is found to be clogging or otherwise affecting the operation of the facility. Access roads will remain clear of vegetation and obstructions.
Significant vegetation removal is covered under the major maintenance activities section below.
Snag Removal
This work typically includes the removal of sticks, dead branches, brush, and small trees that block water flow or otherwise interfere with the operations. This work may be performed as needed on a quarterly basis.
Minor Sediment Removal
It is expected that there will be a minor amount of sediment deposition at points within the storm drain inlet, primarily in forebay(s) near the inlet(s). When such deposits obstruct water flow, the deposits will be removed.

What is stormwater runoff?
Why is stormwater runoff
a problem?
The effects of pollution
Stormwater runoff occurs when precipitation
from rain or snowmelt flows over the ground.
Impervious surfaces like driveways, sidewalks,
and streets prevent stormwater from
naturally soaking into the ground.
Stormwater can pick up debris, chemicals, dirt, and other pollutants and flow into a storm sewer system or directly to a lake, stream, river, wetland, or coastal water. Anything that enters a storm sewer system is discharged untreated into the waterbodies we use for swimming, fishing, and providing drinking water.
Polluted stormwater runoff can have
many adverse effects on plants, fish,
animals, and people.
Sediment can cloud the water
and make it difficult or
impossible for aquatic plants to
grow . Sediment also can
.
/c183
destroy aquatic habitats
Excess nutrients can cause
algae blooms. When algae die,
they sink to the bottom and decompose
in a process that removes oxygen from
the water. Fish and other aquatic
organisms can’t exist in water with low
dissolved oxygen levels.
Bacteria and other pathogens can wash
into swimming areas and create health
hazards, often making beach closures
necessary .
Debris—plastic bags, six-pack rings, bottles, and
cigarette butts—washed into waterbodies can choke, suffocate, or disable aquatic life like ducks, fish, turtles, and birds.
Household hazardous wastes like insecticides, pesticides, paint, solvents, used motor oil, and other auto fluids can poison aquatic life.
Land animals and people can become sick or die from eating diseased fish and shellfish or ingesting polluted water.
Polluted stormwater often
affects drinking water
sources. This, in turn, can
affect human health and
increase drinking water
treatment costs.

Auto care
Washing your car and
degreasing auto parts at home
can send detergents and other
contaminants through the
storm sewer system. Dumping
automotive fluids into storm
drains has the same result as
dumping the materials directly
into a waterbody .
Pet waste
Pet waste can be
a major source of
bacteria and
excess nutrients
in local waters.
/c183
When walking
your pet,
remember to pick up the
waste and dispose of it
properly . Flushing pet
waste is the best disposal
method. Leaving pet waste
on the ground increases
public health risks by
allowing harmful bacteria
and nutrients to wash into
the storm drain and
eventually into local
waterbodies.
Septic
systems
Leaking and
poorly
maintained
septic
systems release nutrients and
pathogens (bacteria and
viruses) that can be picked up
by stormwater and discharged
into nearby waterbodies.
Pathogens can cause public
health problems and
environmental concerns.
Lawn care
Excess fertilizers
and pesticides
applied to lawns
and gardens wash
off and pollute
streams. In
addition, yard
clippings and
leaves can wash
into storm drains and contribute
nutrients and organic matter to streams.
Education is essential to changing people's behavior.
Signs and markers near storm drains warn residents
that pollutants entering the drains will be carried
untreated into a local waterbody.
Recycle or properly dispose of household products that
contain chemicals, such as insecticides, pesticides, paint, solvents, and used motor oil and other auto fluids.
Don’t pour them onto the ground or into storm drains.
/c183
/c183
Use a commercial car wash that treats or
recycles its wastewater, or wash your car on
your yard so the water infiltrates into the
ground.
Repair leaks and dispose of used auto fluids
and batteries at designated drop-off or
recycling locations.
/c183
/c183
/c183
/c183
Don’t overwater your lawn. Consider
using a soaker hose instead of a
sprinkler.
Use pesticides and fertilizers
sparingly . When use is necessary , use
these chemicals in the recommended
amounts. Use organic mulch or safer
pest control methods whenever
possible.
Compost or mulch yard waste. Don’t
leave it in the street or sweep it into
storm drains or streams.
Cover piles of dirt or mulch being
used in landscaping projects.
/c183
/c183
Inspect your system every
3 years and pump your
tank as necessary (every 3
to 5 years).
Don't dispose of
household hazardous
waste in sinks or toilets.
Dirt, oil, and debris that collect in
parking lots and paved areas can be
washed into the storm sewer system
and eventually enter local
waterbodies.
/c183
/c183
/c183
Sweep up litter and debris from
sidewalks, driveways and parking lots,
especially around storm drains.
Cover grease storage and dumpsters
and keep them clean to avoid leaks.
Report any chemical spill to the local
hazardous waste cleanup team.
They’ll know the best way to keep
spills from harming the environment.
Erosion controls that aren’t maintained can cause
excessive amounts of sediment and debris to be
carried into the stormwater system. Construction
vehicles can leak fuel, oil, and other harmful fluids
that can be picked up by stormwater and
deposited into local waterbodies.
/c183
/c183
/c183
Divert stormwater away from disturbed or
exposed areas of the construction site.
Install silt fences, vehicle mud removal areas,
vegetative cover, and other sediment and
erosion controls and properly maintain them,
especially after rainstorms.
Prevent soil erosion by minimizing disturbed
areas during construction projects, and seed
and mulch bare areas as soon as possible.
Uncovered fueling stations allow spills to be
washed into storm drains. Cars waiting to be
repaired can leak fuel, oil, and other harmful
fluids that can be picked up by stormwater.
/c183
/c183
/c183
/c183
Clean up spills immediately and properly
dispose of cleanup materials.
Provide cover over fueling stations and
design or retrofit facilities for spill
containment.
Properly maintain fleet vehicles to prevent
oil, gas, and other discharges from being
washed into local waterbodies.
Install and maintain oil/water separators.
Lack of vegetation on streambanks can lead to erosion. Overgrazed pastures can also contribute excessive amounts of sediment to local waterbodies. Excess fertilizers and pesticides can poison aquatic animals and lead to destructive algae blooms. Livestock in streams can contaminate waterways with bacteria, making them unsafe for human contact. /c183
/c183
/c183
/c183
/c183
Keep livestock away from streambanks and provide
them a water source away from waterbodies.
Store and apply manure away from waterbodies and in
accordance with a nutrient management plan.
Vegetate riparian areas along waterways.
Rotate animal grazing to prevent soil erosion in fields.
Apply fertilizers and pesticides according to label
instructions to save money and minimize pollution.
Permeable Pavement
Rain Barrels
Rain Gardens and
Grassy Swales
Vegetated Filter Strips
—Traditional concrete and
asphalt don’t allow water to soak into the ground.
Instead these surfaces rely on storm drains to
divert unwanted water. Permeable pavement
systems allow rain and snowmelt to soak through,
decreasing stormwater runoff.
—You can
collect rainwater from
rooftops in mosquito-
proof containers. The
water can be used later on
lawn or garden areas.
—Specially
designed areas planted
with native plants can provide natural places for
rainwater to collect
and soak into the
ground. Rain from
rooftop areas or paved
areas can be diverted
into these areas rather
than into storm drains.
—Filter strips are areas of
native grass or plants created along roadways or
streams. They trap the pollutants stormwater
picks up as it flows across driveways and streets.
Residential landscaping
