Section IV Best Management Practices (BMPs)
IV. 1 Project Performance Criteria
Describe project performance criteria. Several steps must be followed in order to determine what
performance criteria will apply to a project. These steps include:
If the project has an approved WIHMP or equivalent, then any watershed specific criteria
must be used and the project can evaluate participation in the approved regional or sub-
regional opportunities. (Please ask your assigned planner or plan checker regarding
whether your project is part of an approved WIHMP or equivalent.)
Determine applicable hydromodification control performance criteria. Refer to Section 7.II-
2.4.2.2 of the Model WQMP.
Determine applicable LID performance criteria. Refer to Section 7.II-2.4.3 of the Model WQMP.
Determine applicable treatment control BMP performance criteria. Refer to Section 7.II-3.2.2 of
the Model WQMP.
Calculate the LID design storm capture volume for the project. Refer to Section 7.II-2.4.3 of the
Model WQMP.
(NOC Permit Area only) Is there an approved WIHMP or equivalent
for the project area that includes more stringent LID feasibility
criteria or if there are opportunities identified for implementing LID
on regional or sub-regional basis?
YES
NO X
If yes, describe WIHMP
feasibility criteria or
regional/sub-regional LID
opportunities.
Project Performance Criteria
If HCOC exists,
list applicable
hydromodification
control
performance
criteria (Section
7.II-2.4.2.2 in
MWQMP)
According to Orange County Model WQMP, 7.II–2.4.2.2, a project does not
have an HCOC if either of the following conditions is met:
• The volumes and time of concentration of stormwater runoff for the post-
development condition do not significantly exceed those of the pre-
development condition for a two-year frequency storm event (a difference of
five percent or less is considered insignificant).
• The site infiltrates at least the runoff from a two-year storm event.
Priority Project Water Quality Management Plan (WQMP) 413 Via Lido Soud
413 Via Lido Nord, Newport Beach, CA 92663
Section IV
Page 11
For this project, the calculated volumes and time of concentration of
stormwater runoff for the post-development condition are less than those of
the pre-development condition for a two-year frequency storm event.
Therefore, HCOC does not exist. A copy of the hydrology calculations for a
two-year frequency storm event is included in Appendix B.
List applicable LID
performance
criteria (Section
7.II-2.4.3 from
MWQMP)
Per 7.II-2.4.2.3 of the Model WQMP, the available LID Treatment BMPs to be
utilized in reducing the post-development impacts include shallow infiltration,
harvest and use, evapotranspiration, or biotreat/biofilter, of the 85th percentile
of a 24-hour storm event.
Per 7.II-3.2.2 of the Model WQMP, if the LID performance criteria are not
feasibly met by retention and/or biotreatment, then sizing of onsite treatment

include, if applicable, any Water Quality credits as calculated per the
Technical Guidance Document. If the additional required volume cannot be
met, however has a medium to high effectiveness for reducing the primary
POCs, the project is considered to be in compliance, then a waiver application
and participation in an alternative program may be not required. If the cost of
providing treatment control BMPs greatly outweighs the pollution control
benefits, a waiver of treatment control and LID requirements can be requested.

IV.2. Site Design and Drainage
Describe site design and drainage including
A narrative of site design practices utilized or rationale for not using practices;
A narrative of how site is designed to allow BMPs to be incorporated to the MEP
A table of DMA characteristics and list of LID BMPs proposed in each DMA.
Reference to the WQMP “BMP Exhibit.”
Calculation of Design Capture Volume (DCV) for each drainage area.
A listing of GIS coordinates for LID and Treatment Control BMPs.
Refer to Section 2.4.2 in the Technical Guidance Document (TGD).
The site consists of one (1) Drainage Management Area (DMA #1) as noted below. The proposed
DMA was derived from the project’s separately prepared Hydrology Report based on the proposed
drainage design. Storm water collected by roof gutter downspouts will be pre-treated by downspout
filter boxes prior to discharge to the proposed subsurface drainage system. Runoff water will be
collected by surface drainage inlets on both side yards to subsurface yard drainage pipe systems. The
subsurface drainage pipes conveyed runoff water to four, 15’ long each, trench drains located at front
and rear ends of both side yards to infiltrate runoff water onsite maximum extent possible (MEP).
The remaining runoff water if present will be continued to be conveyed down toward a 27’ long
bottomless trench drain system located along the center of the rear yard deck to infiltrate runoff
water MEP. Surface runoff water collected at rear yard deck will be conveyed down to the bottomless
trench drain via three, 10” diameter deck drain with overflow.
The site design practices utilized on the project include the following:
Minimize Impervious Area:
Impervious areas are minimized by the use of minimum allowable driveway and parking
requirements, as well as landscaping planters.
Maximize Natural Infiltration Capacity:
Per the Preliminary Geotechnical Engineering Investigation Report by Coast Geotechnical, Inc
dated March 10, 2022, The earth materials encountered were classified as artificial fill underlain by
native soils to the maximum depth explored Artificial fills encountered consisted of slightly silty,
fine to medium-grained sand, tan in color, damp and generally loose to medium dense. The fills
were encountered to a depth of about 1.5 to 2 feet existing grade in the borings. Native soils
encountered consisted of clean, fine to medium-grained sand, light gray tan and dark gray in
color, damp to wet and generally medium dense, to maximum depth explored of 12.5 feet.
Four, 15’ long, 12” wide by 18” deep trench drains and one, 27’ long, 24” wide by 18” deep bottomless
trench drain will be utilized to infiltrate runoff water at the site.

Disconnect Impervious Areas:
Surface runoff water from impervious areas will be directed to the proposed trench drains at front
and rear ends at both side yards and bottomless trench drain at rear yard deck area.
Protect existing vegetation or sensitive areas:
None on site.
Re-vegetate Disturbed Areas:
The disturbed areas will be planted with ground cover and a combination of native or drought
tolerant plants and trees.

down to the proposed 27’ long, 24” wide by 18” deep bottomless trench drain at lower rear yard deck
area.
Using Worksheet C from TGD and presented in Attachment E, the storage volume with 48 hour
draw down time calculated per Worksheet C is 170.2 cu.ft which exceeds DCV of 170.2 cu.ft. Design
infiltration BMPs using four, 15' long each, 12"(W) x 18" (D) trench drains and one, 27' long, 24" (W) x
18" (D) bottomless trench drain.
Total areas of trench drains and bottomless trench drain provided is 4x1'x15'+27'x2' = 114 sq. ft.
Vproposed = A*Ponding depth (dp) → 114 sq. ft. * (18"/12) ft = 171 cu. ft. > Vdesign = 170.2 cu-ft., OK
Thus, the proposed four, 15’ long each, trench drains and one 27’ long bottomless trench drain at the
site are sized to fully treat the calculated construction drawdown volume of 171 cu-ft which exceeds
the design volume of 170.2 cu-ft. and DCV of 170.2 cu-ft.

Describe an alternative compliance plan (if applicable). Include alternative compliance obligations
(i.e., gallons, pounds) and describe proposed alternative compliance measures. Refer to Section 7.II
3.0 in the WQMP.
IV.4.1 Water Quality Credits
Determine if water quality credits are applicable for the project. Refer to Section 3.1 of the Model
WQMP for description of credits and Appendix VI of the Technical Guidance Document (TGD) for
calculation methods for applying water quality credits.
Description of Proposed Project
Project Types that Qualify for Water Quality Credits (Select all that apply):
Redevelopment
projects that reduce the
overall impervious
footprint of the project
site.
Brownfield redevelopment, meaning
redevelopment, expansion, or reuse of real
property which may be complicated by the
presence or potential presence of hazardous
substances, pollutants or contaminants, and
which have the potential to contribute to
adverse ground or surface WQ if not
redeveloped.
Higher density development projects which
include two distinct categories (credits can only
be taken for one category): those with more
than seven units per acre of development (lower
credit allowance); vertical density
developments, for example, those with a Floor
to Area Ratio (FAR) of 2 or those having more
than 18 units per acre (greater credit allowance).
Mixed use development, such as a
combination of residential, commercial,
industrial, office, institutional, or other land
uses which incorporate design principles that
can demonstrate environmental benefits that
would not be realized through single use
projects (e.g. reduced vehicle trip traffic with
the potential to reduce sources of water or air
pollution).
Transit-oriented developments, such as a
mixed use residential or commercial area
designed to maximize access to public
transportation; similar to above criterion, but
where the development center is within one
half mile of a mass transit center (e.g. bus, rail,
light rail or commuter train station). Such
projects would not be able to take credit for
both categories, but may have greater credit
assigned
Redevelopment projects
in an established historic
district, historic
preservation area, or similar
significant city area
including core City Center
areas (to be defined through
mapping).
Developments with
dedication of
undeveloped portions to
parks, preservation
areas and other pervious
uses.
Developments
in a city center
area.
Developments
in historic
districts or
historic
preservation
areas.
Live-work
developments, a variety of
developments designed to
support residential and
vocational needs together –
similar to criteria to mixed
use development; would not
be able to take credit for
both categories.
In-fill projects, the
conversion of empty lots
and other underused spaces
into more beneficially used
spaces, such as residential
or commercial areas.

lean beaches
and healthy
creeks, rivers, bays
and ocean are important to
Orange County. However,
many common activities
such as painting can lead
to water pollution if you’re
not careful. Paint must be
used, stored and disposed of
properly to ensure that it does
not enter the street, gutter or
storm drain. Unlike water in
sanitary sewers (from sinks
and toilets), water in storm
drains is not treated before
entering our waterways.
You would never dump paint
into the ocean, so don’t let
it enter the storm drains.
Follow these easy tips to help
prevent water pollution.
For more information,
please call the
Orange County Stormwater Program
at 1-877-89-SPILL (1-877-897-7455)
or visit
www.ocwatersheds.com
To report a spill,

Reporting Hotline
at 1-877-89-SPILL (1-877-897-7455).
For emergencies, dial 911.
The tips contained in this brochure provide useful
information to help prevent water pollution while
using, storing and disposing of paint. If you
have other suggestions, please contact your city’s
stormwater representatives or call the Orange
County Stormwater Program.
Printed on Recycled Paper
Paint can cause significant damage to our
environment. Whether you hire a contractor or
do it yourself, it is important to follow these simple
tips when purchasing, using, cleaning, storing and
disposing of paint.
Purchasing Paint
Measure the room or object to be painted, then buy
only the amount needed.
Whenever possible, use water-based paint since it
usually does not require hazardous solvents such as
paint thinner for cleanup.
Painting
Use only one brush or roller per color of paint to
reduce the amount of water needed for cleaning.
Place open paint containers or trays on a stable
surface and in a position that is unlikely to spill.
Always use a tarp under the area or object being
painted to collect paint drips and contain spills.
Cleaning
Never clean brushes or rinse paint containers in the
street, gutter or storm drain.
For oil-based products, use as much of the paint on
the brushes as possible. Clean brushes with thinner.
To reuse thinner, pour it through a fine filter (e.g.
nylon, metal gauze or filter paper) to remove solids
such as leftover traces of paint.
For water-based products, use as much of the paint
on the brushes as possible, then rinse in the sink.
Collect all paint chips and dust. Chips and dust
from marine paints or paints containing lead,
mercury or tributyl tin are hazardous waste. Sweep
up and dispose of at a Household Hazardous Waste
Collection Center (HHWCC).
Storing Paint
Store paint in a dry location away from the elements.
Store leftover water-based paint, oil-based paint and
solvents separately in original or clearly marked
containers.
Avoid storing paint cans directly on cement floors.
The bottom of the can will rust much faster on
cement.
Place the lid on firmly and store the paint can upside-
down to prevent air from entering. This will keep the
paint usable longer. Oil-based paint is usable for up
to 15 years. Water-based paint remains usable for up
to 10 years.
Alternatives to Disposal
Use excess paint to apply another coat, for touch-ups,
or to paint a closet, garage, basement or attic.
Give extra paint to friends or family. Extra paint can
also be donated to a local theatre group, low-income
housing program or school.
Take extra paint to an exchange program such as the
“Stop & Swap” that allows you to drop off or pick up
partially used home care products free of charge.
“Stop & Swap” programs are available at most
HHWCCs.
For HHWCC locations and hours, call (714) 834-6752
or visit www.oclandfills.com.
Disposing of Paint
Never put wet paint in the trash.
For water-based paint:
If possible, brush the leftover paint on cardboard or
newspaper. Otherwise, allow the paint to dry in the can with the lid off in a well-ventilated area protected
from the elements, children and pets. Stirring the
paint every few days will speed up the drying.
Large quantities of extra paint should be taken to a
HHWCC.
Once dried, paint and painted surfaces may be
disposed of in the trash. When setting a dried paint
can out for trash collection, leave the lid off so the
collector will see that the paint has dried.
For oil-based paint:
Oil-based paint is a household hazardous waste.
All leftover paint should be taken to a HHWCC.
Aerosol paint:
Dispose of aerosol paint cans at a HHWCC.
Spills
Never hose down pavement or other impermeable
surfaces where paint has spilled.
Clean up spills immediately by using an absorbent
material such as cat litter. Cat litter used to clean
water-based paint spills can be disposed of in the
trash. When cleaning oil-based paint spills with cat
litter, it must be taken to a HHWCC.
Immediately report spills that have entered the
street, gutter or storm drain to the County’s 24-Hour
Water Pollution Problem Reporting Hotline at (714) 567-6363 or visit www.ocwatersheds.com to fill out an
incident reporting form.

Rain Gardens
Rain gardens allow runoff to be directed from your roof
downspout into a landscaped area. Vegetation and rocks in
the garden will slow the flow of water to allow for infiltration into
the soil. Plants and soil particles will absorb pollutants from
the roof runoff. By utilizing a native plant palate, rain gardens
can be maintained all year with minimal additional irrigation.
These plants are adapted to the semi-arid climate of Southern
OTHER WATER CONSERvATION AND POLLUTION PREvENTION TECHNIqUES
Native Vegetation and Maintenance
“California Friendly” plants or native vegetation can significantly
reduce water use. These plants often require far less fertilizers
as California, require less water and can reduce your water bill.
Before modifying your yard to install a rain
and pesticides, which are two significant pollutants found in
Orange County waterways. Replacing water “thirsty” plants and
grass types with water efficient natives is a great way to save water garden, please consult your local building and/or
planning departments to ensure your garden plan
follows pertinent building codes and ordinances.
Besides codes and ordinances, some home
owner associations also have guidelines for yard
modifications. If your property is in hill areas
or includes engineered slopes, please seek
professional advice before proceeding
with changes.

Weed Free Yards
Weeds are water thieves.
They often reproduce quickly
and rob your yard of both
water and nutrients. Weed
your yard by hand if possible.
If you use herbicides to
control the weeds, use only
the amount recommended on
the label and never use it if
rain is forecast within the next
48 hours.
Soil Amendments
Soil amendments such as green waste (e.g. grass clippings,
compost, etc.) can be a significant source of nutrients and can help
keep the soil near the roots of plants moist. However, they can
cause algal booms if they get into our waterways, which reduces
the amount of oxygen in the water and impacts most aquatic
organisms. It is important to apply soil amendments more than 48
hours prior to predicted rainfall.
changes. If it is raining, too windy or too cold, the
smart irrigation control sprinklers will automatically shut
off.
Check with your local water agency for available re-
bates on irrigation controllers and smart timers.
• Aim your sprinklers at your lawn, not the sidewalk –
By simply adjusting the direction of your sprinklers
you can save water, prevent water pollution from
runoff, keep your lawn healthy and save money.
• Set a timer for your sprinklers – lawns absorb
the water they need to stay healthy within a few
minutes of turning on the sprinklers. Time your
sprinklers; when water begins running off your
lawn, you can turn them off. Your timer can be set
to water your lawn for this duration every time.
• Water at Sunrise – Watering early in the morning
will reduce water loss due to evaporation.
Additionally, winds tend to die down in the early
morning so the water will get to the lawn as
intended.
• Water by hand – Instead of using sprinklers,
consider watering your yard by hand. Hand-
watering ensures that all plants get the proper
amount of water and you will prevent any water
runoff, which wastes water and carries pollutants
into our waterways.
• Fix leaks - Nationwide, households waste one
trillion gallons of water a year to leaks – that is
enough water to serve the entire state of Texas for
a year. If your garden hose is leaking, replace the
nylon or rubber hose washer and ensure a tight
connection. Fix broken sprinklers immediately.

Preventing water
pollution at your
commercial/industrial site
Clean beaches and healthy creeks, rivers,
bays and ocean are important to Orange
County. However, many landscape and
building maintenance activities can lead to
water pollution if you’re not careful. Paint,
chemicals, plant clippings and other materials
can be blown or washed into storm drains that
flow to the ocean. Unlike water in sanitary
sewers (from sinks and toilets), water in storm
drains is not treated before entering our
waterways.
You would never pour soap or fertilizers into
the ocean, so why would you let them enter the
storm drains? Follow these easy tips to help
prevent water pollution.

to obtain coverage under the State General
Industrial Permit. For more information visit:

Never Dispose
of Anything
in the Storm
Drain.
Landscape Maintenance
Compost grass clippings, leaves, sticks
and other vegetation, or dispose of it at
a permitted landfill or in green waste
containers. Do not dispose of these
materials in the street, gutter or storm
drain.
Irrigate slowly and inspect the system
for leaks, overspraying and runoff.
Adjust automatic timers to avoid
overwatering.
Follow label directions for the use and
disposal of fertilizers and pesticides.
Do not apply pesticides or fertilizers if
rain is expected within 48 hours or if
wind speeds are above 5 mph.
Do not spray pesticides within 100 feet
of waterways.
Fertilizers should be worked into the
soil rather than dumped onto the
surface.
If fertilizer is spilled on the pavement
or sidewalk, sweep it up immediately
and place it back in the container.
Building Maintenance
Never allow washwater, sweepings or
sediment to enter the storm drain.
Sweep up dry spills and use cat litter,
towels or similar materials to absorb wet
spills. Dispose of it in the trash.
If you wash your building, sidewalk or
parking lot, you must contain the water.
Use a shop vac to collect the water and
contact your city or sanitation agency
for proper disposal information. Do
not let water enter the street, gutter or
storm drain.
Use drop cloths underneath outdoor
painting, scraping, and sandblasting
work, and properly dispose of materials
in the trash.
Use a ground cloth or oversized tub for
mixing paint and cleaning tools.
Use a damp mop or broom to clean
floors.
Cover dumpsters to keep insects,
animals, rainwater and sand from
entering. Keep the area around the
dumpster clear of trash and debris. Do
not overfill the dumpster.
Call your trash hauler to replace leaking
dumpsters.
Do not dump any toxic substance or
liquid waste on the pavement, the
ground, or near a
storm drain. Even
materials that
seem harmless
such as latex paint
or biodegradable
cleaners can
damage the
environment.
Recycle paints, solvents and other
materials. For more information about
recycling and collection centers, visit
www.oclandfills.com.
Store materials indoors or under cover
and away from storm drains.
Use a construction and demolition
recycling company to recycle lumber,
paper, cardboard, metals, masonry,
carpet, plastic, pipes, drywall, rocks,
dirt, and green waste. For a listing of

Proper Maintenance Practices for your Business
Before Buying Pest Control Products
• Identify the pest.
• Decide if pest control products are the best control measure or if there
are alternatives available.
• Are integrated pest management guidelines available for this pest?
• Read the product label:
Is the pest listed on the label?
Is it the best product for the pest?
Before Mixing Your Sprayer
• Read the label carefully.
• Buy only enough pesticide to treat the area
affected by the pest.
• Check the weather and don’t apply if
it’s windy or about to rain
• Measure the area you’re treating.
• Calculate how much spray to mix.
• Wear long sleeve shirt, long pants, shoes and any other protective
equipment listed on the label and follow all the label precautions.
• Be prepared for spills and know how to clean them up.
When You’re Ready To Spray
• Mix and load spray in an area where any spilled pesticide will not be
able to drain or be washed away into storm drains, ditches, streams,
ponds or other bodies of water.
• Mix sprayer on grass, not the sidewalk or driveway.
• Mix only as much as needed.
When You’re Spraying
• AVOID spraying in or near storm drains, ditches, streams, and ponds!
• Leave an untreated strip around these areas to protect the water.
When You’re done
• Never dump leftovers down any drain; Save for a future application.
• Triple-rinse sprayer and apply rinsewater to treated area.
• Take any old or unwanted pesticides to a Household Hazardous Waste
Collection Center (714) 834-6752.
With Integrated Pest Management (IPM), homeowners use common
sense and nature to make it difficult for pests to survive. IPM techniques
include cultural practices (such as mulching to prevent weeds),
encouraging natural enemies (good bugs), and judicious use of pest
control products.
• First, identify your pest problem. To find the best solution, you need to
pin down the problem. Consult gardening books, your county
cooperative extension office or your local nursery.
• Decide how much pest control is necessary. If you can live with some
pest damage, you can avoid intensive pest control product treatments.
• Choose an effective option. Try various types of controls first: washing
bugs off plants, pruning diseased parts of plants. If you need to use
pest control products, choose one that targets the problem and poses
the least hazard.
• Finally, it’s easier to prevent pests than to control them.
Think ahead.

C
lean beaches and healthy
creeks, rivers, bays and
ocean are important
to Orange County. However,
many common activities such as
pest control can lead to water
pollution if you’re not careful.
Pesticide treatments must be
planned and applied properly
to ensure that pesticides do
not enter the street, gutter or
storm drain. Unlike water in
sanitary sewers (from sinks and
toilets), water in storm drains is
not treated before entering our
waterways.
You would never dump pesticides
into the ocean, so don’t let it
enter the storm drains. Pesticides
can cause significant damage
to our environment if used
improperly. If you are thinking
of using a pesticide to control a
pest, there are some important
things to consider.

Key Steps to Follow:
Step 1: Correctly identify the pest (insect,
weed, rodent, or disease) and verify that it is actually causing the problem.
This is important
because beneficial
insects are often
mistaken for pests
and sprayed with
pesticides needlessly.
Step 3: If a pesticide must be used, choose the least toxic chemical.
Obtain information on the least toxic pesticides
that are effective at controlling the target
pest from the UC Statewide Integrated Pest Management (IPM) Program’s Web site at
www.ipm.ucdavis.edu.
Seek out the assistance of a Certified Nursery
Professional at a local nursery or garden center when selecting a pesticide. Purchase the
smallest amount of pesticide available.
For general questions you may also visit www.calpoison.org.
Step 6: In the event of accidental spills,
sweep up or use an absorbent agent to remove any excess pesticides. Avoid the use of water.
Be prepared. Have a broom, dust pan, or dry
absorbent material, such as cat litter, newspapers
or paper towels, ready to assist in cleaning up spills.
Contain and clean up the spill right away. Place
Three life stages of the common lady
beetle, a beneficial insect. Consult with a
Certified Nursery Apply the pesticide to the pest during its most
contaminated materials in a doubled plastic bag. All materials used to clean up the spill should
Professional at a local nursery or garden center or send a sample of the pest to the Orange
County Agricultural Commissioner’s Office.
Determine if the pest is still present – even though you see damage, the pest may have left.
Step 2: Determine
how many pests are present and causing damage.
Small pest populations
may be controlled more safely using non-
pesticide techniques. These include removing
food sources, washing off leaves with a strong
stream of water, blocking entry into the home using caulking and replacing problem plants
with ones less susceptible to pests.
Integrated Pest Management (IPM)
usually combines several least toxic pest
control methods for long-term prevention
and management of pest problems
without harming you, your family,
or the environment.
vulnerable life stage. This information can be found on the pesticide label.
Step 4: Wear appropriate protective clothing.
Follow pesticide labels regarding specific types
of protective equipment you should wear.
Protective clothing should always be washed
separately from other clothing.
Step 5: Continuously monitor external
conditions when applying pesticides such as weather, irrigation, and the presence of children and animals.
Never apply pesticides when rain is predicted
within the next 48 hours. Also, do not water
after applying pesticides unless the directions say it is necessary.
Apply pesticides when the air is still; breezy
conditions may cause the spray or dust to drift
away from your targeted area.
In case of an emergency call 911 and/or the
regional poison control number at
(714) 634-5988 or (800) 544-4404 (CA only).
be properly disposed of according to your local Household Hazardous Waste Disposal site.
Step 7: Properly store and dispose of unused pesticides.
Purchase Ready-To-
Use (RTU) products
to avoid storing
large concentrated
quantities of
pesticides.
Store unused chemicals in a locked cabinet.
Unused pesticide chemicals may be disposed
of at a Household Hazardous Waste Collection
Center.
Empty pesticide containers should be triple
rinsed prior to disposing of them in the trash.

Tips for Pest Control
Did you know that just
one quart of oil can pollute 250,000
gallons of w ater?
A clean ocean and healthy cr eeks, rivers,
bays and beaches are important to Orange
County. However, not properly disposing of
used oil can lead to water pollution. If you
pour or drain oil onto driveways, sidewalks
or streets, it can be washed into the storm
drain. Unlike water in sanitary sewers (from
sinks and toilets), water in stor m drains is not
tr eated befor e entering the ocean. Help
prevent water pollution by taking your used oil
to a used oil collection center.
Included in this brochure is a list of
locations that will accept up to five gallons
of used motor oil at no cost. Many also
accept used oil filters. Please contact the
facility befor e delivering your used oil. This
listing of companies is for your reference
and does not constitute a r ecommendation
or endorsement of the company.
Please note that used oil filters may not be
disposed of with regular household trash.
They must be taken to a household
hazar dous waste collection or recycling
center in Anaheim, Huntington Beach,
Irvine or San Juan Capistrano. For
information about these centers, visit
www.oclandfills.com.
Please do not mix your oil with other
substances!

What is a
Sewage Spill?
Sewage spills occur when the wastewater being
transported via underground pipes overflows through
a manhole, cleanout or broken pipe. Sewage spills can
cause health hazards, damage to homes and businesses,
and threaten the environment, local waterways and
beaches.
Common Causes of Sewage Spills
Grease builds up inside and eventually blocks sewer
pipes. Grease gets into the sewer from food
Overflowing cleanout pipe located on private property
You Could Be Liable
establishments, household drains, as well as from poorly
maintained commercial grease traps and interceptors.
Structure problems caused by tree roots in the lines,
broken/cracked pipes, missing or broken cleanout caps or undersized sewers can cause blockages.
Infiltration and inflow (I/I) impacts pipe capacity and
is caused when groundwater or rainwater enters the
sewer system through pipe defects and illegal
connections.
You Are Responsible for a
Sewage Spill Caused by a Blockage
or Break in Your Sewer Lines!
Time is of the essence in dealing with sewage spills. You
are required to immediately:
Control and minimize the spill. Keep spills contained
on private property and out of gutters, storm drains and
public waterways by shutting off or not using the water.
Use sandbags, dirt and/or plastic sheeting to
prevent sewage from entering the storm drain system.
Clear the sewer blockage. Always wear gloves and
wash your hands. It is recommended that a plumbing
professional be called for clearing blockages and making
necessary repairs.
Always notify your city sewer/public works
department or public sewer district of sewage
spills. If the spill enters the storm drains also notify the
Health Care Agency. In addition, if it exceeds 1,000
gallons notify the Office of Emergency Services. Refer to
the numbers listed in this brochure.
Allowing sewage from your home, business or property to discharge to a gutter or storm drain may subject you to
penalties and/or out-of-pocket costs to reimburse cities
or public agencies for clean-up and enforcement efforts.
See Regulatory Codes & Fines section for pertinent codes
and fines that apply.
What to Look For
Sewage spills can be a very noticeable gushing of water
from a manhole or a slow water leak that may take time to
be noticed. Don’t dismiss unaccounted-for wet areas.
Look for:
. Drain backups inside the building.
. Wet ground and water leaking around manhole lids
onto your street.
. Leaking water from cleanouts or outside drains.
. Unusual odorous wet areas: sidewalks, external
walls or ground/landscape around a building.
Caution
Keep people and pets away from the affected area.
Untreated sewage has high levels of disease-causing
viruses and bacteria. Call your local health care agency
listed on the back for more information.
If You See a Sewage Spill Occurring,
Notify Your City Sewer/Public Works
Department or Public Sewer District
IMMEDIATELY!

Grease Blockages
The drain is not a dump! Recycle or dispose of grease
properly and never pour grease down the drain.
Homeowners should mix fats, oils and grease with absor-
waste materials such as paper, coffee grounds, or kitty
and place it in the trash. Wipe food scraps from plates
pans and dump them in the trash.
Restaurants and commercial food service establishments
should always use “Kitchen Best Management Practices.”
These include:
Collecting all cooking grease and liquid oil from pots, pans
and fryers in covered grease containers for recycling.
Scraping or dry-wiping excess food and grease from
dishes, pots, pans and fryers into the trash.
Installing drain screens on all kitchen drains.
Having spill kits readily available for cleaning up spills.
Properly maintaining grease traps or interceptors by having
them serviced regularly. Check your local city codes.
You Could Be Liable
for Not Protecting
the Environment
Local and state agencies have legal jurisdic-
tion and enforcement authority to ensure that
sewage spills are remedied.
They may respond and assist with contain-
ment, relieving pipe blockages, and/or
clean-up of the sewage spill, especially if
the spill is flowing into storm drains or onto
public property.
A property owner may be charged for
costs incurred by these agencies
responding to spills from private
properties .

lean beaches
and healthy
creeks, rivers, bays
and ocean are important to
Orange County. However, many
common activities can lead to
water pollution if you’re not
careful. Home improvement
projects and work sites must
be maintained to ensure that
building materials do not enter
the street, gutter or storm drain.
Unlike water in sanitary sewers
(from sinks and toilets), water
in storm drains is not treated
before entering our waterways.
You would never dump building
materials into the ocean, so
don’t let them enter the storm
drains. Follow these tips to help
prevent water pollution.

Home improvement projects can cause significant
damage to the environment. Whether you hire
a contractor or work on the house yourself, it
is important to follow these simple tips while
renovating, remodeling or improving your home:
General Construction
Schedule projects for dry
weather.
Keep all construction debris
away from the street, gutter
and storm drain.
Store materials under cover
with temporary roofs or plastic
sheets to eliminate or reduce
the possibility that rainfall,
runoff or wind will carry
materials from the project site
to the street, storm drain or
adjacent properties.
Building Materials
Never hose materials into a street, gutter or storm
drain.
Exposed piles of construction material should not be
stored on the street or sidewalk.
Minimize waste by ordering only the amount of
materials needed to complete the job.
Do not mix more fresh concrete than is needed for
each project.
Wash concrete mixers and equipment in a
designated washout area where the water can flow
into a containment area or onto dirt.
Dispose of small amounts of dry excess materials in
the trash. Powdery waste, such as dry concrete, must
be properly contained within a box or bag prior to
disposal. Call your local trash hauler for weight and
size limits.
Paint
Measure the room or object to be painted, then buy
only the amount needed.
Place the lid on firmly and store the paint can upside-
down in a dry location away from the elements.
Tools such as brushes, buckets and rags should never
be washed where excess water can drain into the
street, gutter or storm drain. All tools should be
rinsed in a sink connected to the sanitary sewer.
When disposing of paint, never put wet paint in the
trash.
Dispose of water-based paint by removing the lid
and letting it dry
in the can. Large
amounts must be
taken to a Household
Hazardous Waste
Collection Center
(HHWCC).
Oil-based paint is a
household hazardous
waste. All leftover
paint should be taken
to a HHWCC.
For HHWCC locations and hours, call (714) 834-6752
or visit www.oclandfills.com.
Erosion Control
Schedule grading and excavation projects for dry
weather.
When temporarily removing soil, pile it in a
contained, covered area where it cannot spill
into the street, or obtain the required temporary
encroachment or street closure permit and follow the
conditions instructed by the permit.
When permanently removing large quantities of
soil, a disposal location must be found prior to
excavation. Numerous businesses are available to
handle disposal needs. For disposal options, visit
www.ciwmb.ca.gov/SWIS.
Prevent erosion by planting fast-growing annual and
perennial grasses. They will shield and bind the soil.
Recycle
Use a construction and demolition recycling
company to recycle
lumber, paper,
cardboard, metals,
masonry (bricks,
concrete, etc.), carpet,
plastic, pipes (plastic,
metal and clay),
drywall, rocks, dirt and
green waste.
For a listing of construction and demolition recycling
locations in your area, visit www.ciwmb.ca.gov/recycle.
Spills
Clean up spills immediately by using an absorbent
material such as cat litter, then sweep it up and
dispose of it in the trash.
Immediately report spills that have entered the street,
gutter or storm drain to the County’s 24-Hour Water
Pollution Problem Reporting Hotline at (714) 567-6363 or visit www.ocwatersheds.com to fill out an incident reporting form.

Printed on Recycled Paper
Never allow gardening products or
polluted water to enter the street, gutter
or storm drain.
General Landscaping Tips
Protect stockpiles and materials from
wind and rain by storing them under
tarps or secured plastic sheeting.
Prevent erosion of slopes by planting
fast-growing, dense ground covering
plants. These will shield and bind the
soil.
Plant native vegetation
to reduce the amount
of water, fertilizers, and
pesticide applied to the
landscape.
Never apply pesticides
or fertilizers when rain is
predicted within the next 48 hours.
Garden & Lawn Maintenance
Do not overwater. Use irrigation
practices such as drip irrigation,
soaker hoses or micro spray systems.
Periodically inspect and fix leaks and
misdirected sprinklers.
Do not rake or blow
leaves, clippings or
pruning waste into
the street, gutter
or storm drain.
Instead, dispose
of green waste by
composting, hauling
it to a permitted
landfill, or recycling it through your
city’s program.
Use slow-release fertilizers to
minimize leaching, and use organic
fertilizers.
Read labels and use only as directed.
Do not over-apply pesticides or
fertilizers. Apply to spots as needed,
rather than blanketing an entire
area.
Store pesticides, fertilizers and other
chemicals in a dry covered area to
prevent exposure that may result
in the deterioration
of containers and
packaging.
Rinse empty
pesticide containers
and re-use rinse water
as you would use the
product. Do not dump rinse water
down storm drains. Dispose of empty
containers in the trash.
When available, use non-toxic
alternatives to traditional pesticides,
and use pesticides specifically
designed to control the pest you are
targeting. For more information, visit
www.ipm.ucdavis.edu.
If fertilizer is spilled, sweep up the
spill before irrigating. If the spill is
liquid, apply an absorbent material
such as cat litter, and then sweep it up
and dispose of it in the trash.
Take unwanted pesticides to a
Household Hazardous Waste
Collection Center to be recycled.

Printed on Recycled Paper
Never let any pet care products or
washwater run off your yard and into
the street, gutter or storm drain.
Washing Your Pets
Even biodegradable soaps and

life and the environment.
If possible, bathe your pets indoors
using less-toxic shampoos or have
your pet professionally groomed.
Follow instructions on the products
and clean up spills.
If you bathe your pet outside, wash it
on your lawn or another absorbent/
permeable surface to keep the
washwater from running into the

Why You Should Pick Up After
Your Pet
It’s the law!
Every city has
an ordinance
requiring you
to pick up
after your pet.
Besides being
a nuisance, pet
waste can lead to water pollution, even
if you live inland. During rainfall, pet
waste left outdoors can wash into storm
drains. This waste flows directly into our
waterways and the ocean where it can
harm human health, marine life and
the environment.
As it decomposes, pet waste demands
a high level of oxygen from water.
This decomposition can contribute to
killing marine
life by reducing
the amount of
dissolved oxygen
available to
them.
Have fun with
your pets, but
please be a
responsible pet
owner by taking
care of them and the environment.
Take a bag with you on walks to pick
up after your pet.
Dispose of the waste in the trash or in
a toilet.

ow pollutants to enter the
street, gutter or storm drain!
Follow these simple steps to help reduce water
pollution:
Household Activities
Do not rinse spills with water Use dry cleanup
methods such as applying cat litter or another
absorbent material, sweep and dispose of in
the trash Take items such as used or excess
batteries, oven cleaners, automotive fluids,
painting products and cathode ray tubes, like
TVs and computer monitors, to a Household
Hazardous Waste Collection Center (HHWCC)
For a HHWCC near you call (714) 834-6752 or
visit www oclandfills com
Do not hose down your driveway, sidewalk or
patio to the street, gutter or storm drain Sweep
up debris and dispose of it in the trash
Automotive
Take your vehicle to a commercial car
wash whenever possible If you wash your
vehicle at home, choose soaps, cleaners, or
detergents labeled non-toxic, phosphate- free
or biodegradable Vegetable and citrus-based
products are typically safest for the environment
Do not allow washwater from vehicle washing
to drain into the street, gutter or storm drain
Excess washwater should be disposed of in the
sanitary sewer (through a sink or toilet) or onto
an absorbent surface like your lawn
Monitor your vehicles for leaks and place a pan
under leaks Keep your vehicles well maintained
to stop and prevent leaks
Never pour oil or antifreeze in the street, gutter
or storm drain Recycle these substances at a
service station, a waste oil collection center or
used oil recycling center For the nearest Used
Oil Collection Center call 1-800-CLEANUP or
visit www 1800cleanup org
Pool Maintenance
Pool and spa water must be dechlorinated and free
of excess acid, alkali or color to be allowed in the
street, gutter or storm drain
When it is not raining, drain dechlorinated pool and
spa water directly into the
sanitary sewer
Some cities may have ordinances that do not allow
pool water to be disposed of in the storm drain
Check with your city
Landscape and Gardening
Do not over-water Water your lawn and garden by
hand to control the amount of water you use or set
irrigation systems to reflect seasonal water needs
If water flows off your yard onto your driveway or
sidewalk, your system is over-watering Periodically
inspect and fix leaks and misdirected sprinklers
Do not rake or blow leaves, clippings or pruning
waste into the street, gutter or storm drain Instead,
dispose of waste by composting, hauling it to a
permitted landfill, or as green waste through your
city’s recycling program
Follow directions on pesticides and fertilizer,
(measure, do not estimate amounts) and do not use
if rain is predicted within 48 hours
Take unwanted pesticides to a HHWCC to be
recycled For locations and hours of HHWCC, call
(714) 834-6752 or visit www oclandfills com
Trash
Place trash and litter that cannot be recycled in
securely covered trash cans
Whenever possible, buy recycled products
Remember: Reduce, Reuse, Recycle
Pet Care
Always pick up after your pet Flush waste down
the toilet or dispose of it in the trash Pet waste,
if left outdoors, can wash into the street, gutter
or storm drain
If possible, bathe your pets indoors If you must
bathe your pet outside, wash it on your lawn or
another absorbent/permeable surface to keep
the washwater from entering the street, gutter or
storm drain
Follow directions for use of pet care products
and dispose of any unused products at a
HHWCC

Did You Know?
Most people believe that the largest source
of water pollution in urban areas comes from
specific sources such as factories and sewage
treatment plants In fact, the largest source
of water pollution comes from city streets,
neighborhoods, construction sites and parking
lots This type of pollution is sometimes
called “non-point source” pollution
There are two types of non-point source
pollution: stormwater and urban runoff
pollution
Stormwater runoff results from rainfall
When rainstorms cause large volumes
of water to rinse the urban landscape,
picking up pollutants along the way
Urban runoff can happen any time of
the year when excessive water use from
irrigation, vehicle washing and other
sources carries trash, lawn clippings and
other urban pollutants into storm drains
Where Does It Go?
Anything we use outside homes, vehicles and
businesses – like motor oil, paint, pesticides,
fertilizers and cleaners – can be blown or washed
into storm drains
A little water from a garden hose or rain can also
send materials into storm drains
Storm drains are separate from our sanitary
sewer systems; unlike water in sanitary sewers
(from sinks or toilets), water in storm drains is
not treated before entering our waterways
Sources of Non-Point Source Pollution
Automotive leaks and spills
Improper disposal of used oil and other engine
fluids
Metals found in vehicle exhaust, weathered paint,
rust, metal plating and tires
Pesticides and fertilizers from lawns, gardens and
farms
Improper disposal of cleaners, paint and paint
removers
Soil erosion and dust debris from landscape and
construction activities
Litter, lawn clippings, animal waste, and other
organic matter
Oil stains on parking lots and paved surfaces
Dumping one quart of motor oil into a
storm drain can contaminate 250,000
gallons of water.
The Effect on the Ocean
Non-point source
pollution can have
a serious impact
on water quality
in Orange County
Pollutants from the
storm drain system
can harm marine life
as well as coastal and wetland habitats They can
also degrade recreation areas such as beaches,
harbors and bays
Stormwater quality management programs have
been developed throughout Orange County to
educate and encourage the public to protect water
quality, monitor runoff in the storm drain system,
investigate illegal dumping and maintain storm
drains
Support from Orange County residents and
businesses is needed to improve water quality
and reduce urban runoff pollution Proper use
and disposal of materials will help stop pollution
before it reaches the storm drain and the ocean

HYDROLOGY STUDY
INTRODUCTIOIN
The hydrology study presented in this report discusses the design criteria and methodology
utilized for the hydrologic analysis of the subject property. The design criteria and
methodology used in this study follow the Orange County Hydrology Manual. The 2-yr, 24-
hour precipitation depths specified in the Orange County Hydrology Manual are used for
hydrologic analysis of the 2-year, 24-hour storm.
RATIONAL METHOD
Runoff calculations for this study were accomplished using the Rational Method. The Rational
Method is a physically based numerical method where runoff is assumed to be directly
proportional to rainfall and area, less losses for infiltration and depression storage. Flows were
computed based on the Rational formula:
Q= CIA
Where Q = peak discharge (cfs)
C = Runoff coefficient based on land use and soil type
I = Rainfall intensity (in./hr.)
A = Watershed area (acre)
The runoff coefficient represents the ratio of rainfall that runs off the watershed versus the
portion that infiltrates to the soil or is held in depression storage. The runoff coefficient is
dependent on the land use coverage and soil type.
For a typical drainage study, rainfall intensity varies with the watershed time of concentration.
The watershed time of concentration at any given point is defined as the time it would
theoretically take runoff to travel from the most upstream point in the watershed to a
concentration point, as calculated by equations in the Orange County Hydrology Manual.
DRAINAGE AREA
For this project, a total of one drainage area (DMA #1) was utilized for hydrology study
of the subject property.

From Figure D-1, Orange County Hydrology Manual Time of Concentration Tc = 5.8 min.
From Figure B-3 for return frequency 2 yr. Intensity I(t) = atb = (5.702)(5.8-0.574) = 2.08 in/hr.
Q = CIA
Where Q = Runoff in cubic feet per second (cfs)
C = Runoff coefficient representing the ratio of runoff to rainfall
I = The time-averaged rainfall intensity in in./hr. corresponding to the time of

A = Drainage area in acre
C = 0.9 (Ai + (I – Fp)Ap/I) for I > Fp
C = 0.9Ai for I < Fp
Where Fp = Infiltration rate (0.4-Soil Group A, 0.3-Soil Group B, 0.25-Soil Group C, 0.20-Soil

groundwater related concerns? Refer to Appendix
VII (Worksheet I) for guidance on groundwater-related
infiltration feasibility criteria.
X
Provide basis:
Depth to groundwater at the site is greater than 7 feet per TGD Figure XVI-2e.
Per the Preliminary Geotechnical Engineering Investigation Report by Costal Geotechnical,
Inc dated March 10, 2022, groundwater was encountered at a depth of 7 feet below existing
ground. This groundwater level is subject to minor fluctuation due to tidal changes.
Summarize findings of studies provide reference to studies, calculations, maps, data sources,
etc. Provide narrative discussion of study/data source applicability.
2
Would Infiltration BMPs pose significant risk of
increasing risk of geotechnical hazards that cannot
be mitigated to an acceptable level? (Yes if the
answer to any of the following questions is yes, as
established by a geotechnical expert):
The BMP can only be located less than 50 feet
away from slopes steeper than 15 percent
The BMP can only be located less than eight feet
from building foundations or an alternative setback.
A study prepared by a geotechnical professional or
an available watershed study substantiates that
stormwater infiltration would potentially result in
significantly increased risks of geotechnical hazards
that cannot be mitigated to an acceptable level.
X
Provide basis:
Per the Preliminary Geotechnical Engineering Investigation Report by Costal Geotechnical,
Inc dated March 10, 2022, the site is generally rectangular shaped lot and is elongated in a
north to south direction with topography of the property descending gradually from front to rear
on the order of a few feet. groundwater was encountered at a depth of 7 feet below existing
ground. This groundwater level is subject to minor fluctuation due to tidal changes.

4
Is proposed infiltration facility located on HSG D soils or
the site geotechnical investigation identifies presence of soil
characteristics which support categorization as D soils?
X
Provide basis:
The site is located on HSG D Soils per TDG Figure XVI-2a and XVI-2b.
Per Orange County Hydrology Manual, Plate 2B, Hydrological Classifications of Soils, the
site is characterized as Soil Type A.
Per the Preliminary Geotechnical Engineering Investigation Report by Costal
Geotechnical, Inc dated March 10, 2022, The earth materials encountered were classified
as artificial fill underlain by native soils to the maximum depth explored. Artificial fills
encountered consisted of slightly silty, fine to medium-grained sand, tan in color, damp
and generally loose to medium dense. The fills were encountered to a depth of about 1.5
to 2 feet existing grade in the borings. Native soils encountered consisted of clean, fine to
medium-grained sand, light gray tan and dark gray in color, damp to wet and generally
medium dense, to maximum depth explored of 12.5 feet.
Based on OC Hydrology Manual, Plate 2B, Hydrological Classifications of Soils Map and
the Preliminary Geotechnical Engineering Investigation Report by Costal Geotechnical,
Inc dated March 10, 2022, presence of soil characteristics does not support
categorization as D soils.
Summarize findings of studies provide reference to studies, calculations, maps, data sources,
etc. Provide narrative discussion of study/data source applicability.
