Preliminary Operation and Maintenance Plan for the Stormwater Quality BMP Facilities for

BEAUMONT POINTE - PWQMP
August 12, 2025
I. PURPOSE
The primary purpose of this Operations & Maintenance Plan (O&M Plan) shall be to provide a routine maintenance program that maintains the treatment facilities effectiveness.

II. COVERAGE AREA
This project will utilize two (2) primary treatment facility type located on -site:

1. Extended detention basins (2) — Parcel Map 38161 shows Basin B is located between Parcel 4 and Parcel 5. On Parcel Map 38161, Basin C is located between Parcel 5 and Parcel 6.

These facilities treat stormwater runoff from the site and outlet into existing drainage patterns located in the adjacent historical drainage path. Ultimately, the runoff drains to the Santa Ana River through San Timoteo Creek before ending up at the Pacific Ocean.

III. ROUTINE MAINTENANCE ACTIVITIES
Primary maintenance activities include vegetation management, trash and sediment removal, irrigation maintenance and storm drain outlet inspections. Although mosquito abatement is a concern, the basins and swales are designed to fully drain within 24-72 hours and not include permanent pools or standing water. Routine maintenance activities, and the frequency at which they will be conducted, are shown in Table 1 below.

NOTE: Landscape Maintenance Plan should also be reviewed for consistency with vegetation maintenance and any applicable needs for specific plants, shrubs or trees.

Table 1
Routine Maintenance Activities for Basins & Swales
No.

Maintenance Task
Frequency of Task
1 Conduct annual vegetation management during the summer, removing weeds and harvesting vegetation. Remove all grass cuttings and other green waste.

Once a year
2 Trim vegetation at beginning and end of wet season to prevent establishment of woody vegetation, and for aesthetics and mosquito control.

Twice a year (spring and fall)
3 Evaluate health of vegetation and remove or replace any dead or dying plants. Remove all green waste and dispose of properly.

Twice a year
4 If turf grass is included in basin/swale design, conduct regular mowing and remove all grass cuttings. Avoid producing ruts when mowing.

As necessary to not allow grass
over -growth
Remove accumulated trash and debris from the middle and end of the wet season and dispose of trash and debris properly.

Twice a year (January and April)
8 Irrigate during dry weather.

Per Landscape Plans
9 Inspect basins and swales using the attached inspection checklists.

Quarterly, or as needed
IV. PROHIBITIONS
The use of pesticides and quick release fertilizers shall be minimized, and the principles of integrated pest management (IPM) followed:

1. Employ non -chemical controls (biological, physical and cultural controls) before using chemicals to treat a pest problem.

2. Prune plants properly and at the appropriate time of year.

3. Provide adequate irrigation for landscape plants. Do not over water.

4. Limit fertilizer use unless soil testing indicates a deficiency. Slow -release or organic fertilizer is preferable. Check with municipality for specific requirements.

5. Pest control should avoid harming non -target organisms, or negatively affecting air and water quality and public health. Apply chemical controls only when monitoring indicates that preventative and non -chemical methods are not keeping pests below acceptable levels. When pesticides are required, apply the least toxic and the least persistent pesticide that will provide adequate pest control. Do not apply pesticides on a prescheduled basis.

6. Sweep up spilled fertilizer and pesticides. Do not wash away or bury such spills.

7. Do not over apply pesticide. Spray only where the infestation exists. Follow the manufacturer's instructions for mixing and applying materials.

8. Only licensed, trained pesticide applicators shall apply pesticides.

Page 2 ends

Page 1184 of 1772 ends

9. Apply pesticides at the appropriate time to maximize their effectiveness and minimize the likelihood of discharging pesticides into runoff. With the exception of pre -emergent pesticides, avoid application if rain is expected.

10. Unwanted/unused pesticides shall be disposed as hazardous waste.

Standing water shall not remain in the treatment and/or hydromodification management measures for more than five days, to prevent mosquito generation. Should any mosquito issues arise, contact the City of Moreno Valley for the appropriate contact for Mosquito Abatement, as needed for assistance. Mosquito larvicides shall be applied only when absolutely necessary and then only by a licensed professional or contractor.

TIP #1 The average homeowner uses twice
the amount of water needed to keep plants
healthy. Use the watering calculator and index
at bewaterwise.com to know exactly how much
water your plants need.

TIP #2 Check your sprinkler system for leaks,
overspray and broken sprinkler heads. Update
with drip or other more water -efficient
sprinklers where appropriate.

TIP #3 This fall, plant a portion of your
garden with beautiful native and California
Friendly plants. Browse the plant database at
bewaterwise.com to find just the right look for
your outdoor spaces.

TIP #4 Reduce the amount of water -thirsty
grass. Keep only what you need and replace the
rest with less -thirsty plants or permeable
paving.

TIP #5 For the grass you keep, set your
lawnmower blade higher.

TIP #6 Adjust your sprinkler timer downward
in September. Plants need less water when days
are shorter.

TIP #7 Use a broom instead of the hose for
cleaning sidewalks and patios.

TIP #8 Mulch! A layer of bark, gravel, compost,
sawdust or low -growing groundcover evens out
soil temperature and allows better water
retention.

TIP #9 Check the list of invasive plants that
hurt our environment at caleppc.org and
remove any from your garden.

TIP #1 0 Share these tips with your gardener,
neighbors and friends. Water conservation
should be a part of every Southern Californian's
lifestyle, but that doesn't mean we can't have
lush and beautiful outdoor spaces.

?Oiat ;' stormwater runoff?
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.

?die effects fecis of pollution
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
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.

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.
• 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.

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.

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.
• 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.
• 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.

Pet waste
Pet waste can be
a major source of
bacteria and
excess nutrients
in local waters.
• 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.

Resit/Nitwit Izudseapi4g
Permeable Pavement 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.

Rain Barrels You can
collect rainwater from
rooftops in mosquito -
proof containers. The
water can be used later on
lawn or garden areas.

Rain Gardens and
Grassy Swales—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.

Vegetated Filter Strips —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.
rFarestr:

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.
• 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.
• 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.

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.

R _-
,�-
• 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.

Improperly managed logging operations can result in erosion and sedimentation.
• Conduct preharvest planning to prevent erosion and lower costs. • Use logging methods and equipment that minimize soil disturbance. • Plan and design skid trails, yard areas, and truck access roads to minimize stream crossings and avoid disturbing the forest floor. • Construct stream crossings so that they minimize erosion and physical changes to streams.
• Expedite revegetation of cleared areas.

Page 1194 of 1772 ends

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.
• 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.

3.6 Extended Detention Basin
Type of BMP
LID - Biotreatment
Treatment Mechanisms
Sedimentation, Infiltration, Biofiltration, Evapotranspiration, and Evaporation
Minimum Tributary Drainage Area
5 acres
Other Names
Enhanced Water Quality Basin
Overview
The Extended Detention Basin (EDB) is designed to detain the design volume of stormwater, VBMP, and maximize opportunities for volume losses through infiltration, evaporation, evapotranspiration and surface wetting. Additional pollutant removal is provided through sedimentation, in which pollutants can attach to sediment accumulated in the basin through the process of settling. Stormwater enters the EDB through a forebay where any trash, debris, and sediment accumulate for easy removal. Flows from the forebay enter the basin which is vegetated with native grasses that enhance infiltration and evapotranspiration, and which is interspersed with gravel -filled trenches that help further enhance infiltration. Water that does not get infiltrated or evapotranspired is conveyed to the bottom stage of the basin. At the bottom stage of the basin, low or incidental dry weather flows will be treated through a sand filter and collected in a subdrain structure. Any additional flows will be detained in the basin for an extended period by incorporating an outlet structure that is more restrictive than a traditional detention basin outlet. The restrictive outlet structure extends the drawdown time of the basin which further allows particles and associated pollutants to settle out before exiting the basin, while maximizing opportunities for additional incidental volume losses.
