Existing drainage patterns: The existing site is developed, consisting of a
two-story residential building. The site currently drains southerly to an
existing alleyway. Flows are conveyed easterly to Coronado Street and are
collected in a catch basin located at the end of Coronado Street.
Proposed drainage patterns: Proposed improvements to the site include the
construction of one three-story residential property. Under proposed
conditions, runoff will continue draining southerly to the existing alleyway.

II.3 Hydrology
Hydrologic Conditions of
Concerns (HCOCs)
This project is not required to meet HCOC requirements since it is not a
priority project and does not trigger a Water Quality Management Plan
(WQMP).
Existing Condition
The project site currently consists of a two-story residential house. There
are trench drains along the westerly property line that prevent runoff
from westerly properties from entering the site.
The site currently drains southerly to an existing alleyway. Flows are
conveyed easterly to Coronado Street and are collected in a catch basin
located at the end of Coronado Street. The 2-year peak flow rate from
the site is approximately 0.08 cfs.
Proposed Condition
Under proposed conditions, runoff will continue draining southerly to
the existing alleyway. The westerly portion of the proposed building
will drain to a proposed storm drain system via hardlined roof drains
and several area drains located in the westerly walkway. The proposed
storm drain system will discharge into a proposed French drain in
crushed rock along the southerly property line. The 2-year peak flow
rate from the westerly portion of the site is approximately 0.04 cfs.
Similarly, the easterly portion of the proposed building will drain to a
separate proposed storm drain system via several hardlined roof drains
and area drains. Flows will discharge into the abovementioned French
drain along the southerly property line. The 2-year peak flow rate from
the easterly portion of the site is approximately 0.04 cfs.
The total 2-year peak flow rate to the proposed French drain is
approximately 0.08 cfs. A portion of flows will infiltrate, and all
remaining flows will bubble out to the alleyway, similar to existing
conditions.
Associated hydrology maps and calculations are included in the
following pages.

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 Printed on Recycled Paper

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

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

Pet Waste• Pollution: Pet waste carries bacteria through our watersheds and eventually will be washed out to the ocean. This can pose a health risk to swimmers and surfers.
• Solution: Pick up after your pets!
Trash and Debris• Pollution: Trash and debris can enter waterways by wind, littering and careless maintenance of trash receptacles. Street sweeping collects some of this trash; however, much of what isn’t captured ends up in our storm drain system where it flows untreated out to the ocean.
• Solution: Don’t litter and make sure trash containers are properly covered. It is far more expensive to clean up the litter and trash that ends up in our waterways than it is to prevent it in the first place. Come out to one of Orange County’s many locations for Coastal and Inner-Coastal Cleanup Day, which is held in September.
Motor Oil / Vehicle Fluids• Pollution: Oil and petroleum products from our vehicles are toxic to people, wildlife and plants.
• Solution: Fix any leaks from your vehicle and keep the maintenance up on your car. Use absorbent material such as cat litter on oil spills, then sweep it up and dispose of it in the trash. Recycle used motor oil at a local Household Hazardous Waste Collection Center.
Low Impact Development, Water Conservation & Pollution Prevention
The Ocean Begins at Your Front Door
DID YOU KNOW?
Homeowners Guide
for Sustainable Water Use
A TEAM EFFORT
The Orange County Stormwater Program has teamed with the
Municipal Water District of Orange County (MWDOC) and the University
of California Cooperative Extension Program (UCCE) to develop this
pamphlet.
Low Impact Development (LID) and sustainable water use prevents
water pollution and conserves water for drinking and reuse. Reducing
your water use and the amount of water flowing from your home
protects the environment and saves you money.
Thank you for making water protection
a priority!

Pesticides and Fertilizer • Pollution: The same pesticides that are designed to be toxic to pests can have an equally lethal impact on our marine life. The same fertilizer that promotes plant growth in lawns and gardens can also create nuisance algae blooms, which remove oxygen from the water and clog waterways when it decomposes.
• Solution: Never use pesticides or fertilizer within 48 hours of an anticipated rainstorm. Use only as much as is directed on the label and keep it off driveways and sidewalks.
Dirt and Sediment• Pollution: Dirt or sediment can impede the flow of the stormwater and negatively impact stream habitat as it travels through waterways and deposits downstream. Pollutants can attach to sediment, which can then be transported through our waterways.
• Solution: Protect dirt stockpiles by covering them with tarps or secure plastic sheets to prevent wind or rain from allowing dirt or sediment to enter the storm drain system.
Metals• Pollution: Metals and other toxins present in car wash water can harm important plankton, which forms the base of the aquatic food chain.
• Solution: Take your car to a commercial car wash where the wash water is captured and treated at a local wastewater treatment plant.
The Pollution SolutionSeveral residential activities can result in water pollution. Among these activities are car washing and hosing off driveways and sidewalks. Both activities can waste water and result in excess runoff. Water conservation methods described in this pamphlet can prevent considerable amounts of runoff and conserve water. By taking your car to a commercial car wash and by sweeping driveways and sidewalks, you can further prevent the transport of pollutants to Orange County waterways. Here
are some of the common pollutants for which you can be part of the solution:

PA2022-0262
OPTIONS FOR RAINWATER HARvESTINg AND REUSE
Rainwater harvesting is a great way to save money, prevent pollution and reduce potable water use. To harvest your rainwater, simply redirect the runoff from roofs and downspouts to rain barrels. Rain gardens are another option; these reduce runoff as well as encourage infiltration.
Downspout
Disconnection/RedirectionDisconnecting downspouts from pipes running to the gutter prevents runoff from transporting pollutants to the storm drain. Once disconnected, downspouts can be redirected to rain gardens or other vegetated areas, or be connected to a rain barrel.
Rain BarrelsRain barrels capture rainwater flow from roofs for reuse in landscape irrigation. Capacity of rain barrels needed for your home will depend on the amount of roof area and rainfall received. When purchasing your rain barrel, make sure it includes a screen, a spigot to siphon water for use, an overflow tube to allow for excess water to run out and a connector if you wish to connect multiple barrels to add capacity of water storage.
Mosquito growth prevention is very important when installing a rain barrel. The best way to prevent mosquito breeding is to eliminate entry points by ensuring all openings are sealed tightly. If these methods are unsuccessful, products are available to kill mosquito larvae, but that are harmless to animals and humans. Regular application of these products is essential. Please visit the Orange County Vector Control website for more information at www.ocvcd.org/mosquitoes3.php.
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 California, require less water and can reduce your water bill.
Before modifying your yard to install a rain
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.
R U N O F F , R A I N W A T E R A N D R E U S E
For information on how to disconnect a downspout or to install and maintain a
rain barrel or rain garden at your home, please see the Los Angeles Rainwater
Harvesting Program, A Homeowner’s “How-To” Guide, November 2009 at
www.larainwaterharvesting.org/
Water runoff from sprinklers left on too long will carry pollutants into our waterways.
Permeable pavement allows water runoff to
infiltrate through the soil and prevents most
pollutants from reaching the storm drain system.
What is Low Impact Development (LID)?
Low Impact Development (LID) is a method of development that seeks to maintain the natural
hydrologic character of an area. LID provides a more sustainable and pollution-preventative
approach to water management.
New water quality regulations require implementation of LID in larger new developments and
encourage implementation of LID and other sustainable practices in existing residential areas.
Implementing modifications to your lawn or garden can reduce pollution in our environment, conserve
water and reduce your water bill.
Where Does Water Runoff Go?
Stormwater, or water from rainfall events, and runoff from outdoor water use such as
sprinklers and hoses flows from homes directly into catch basins and the storm drain
system. After entering the storm drain, the water flows untreated into streams, rivers,
bays and ultimately the Pacific Ocean. Runoff can come from lawns, gardens, driveways,
sidewalks and roofs. As it flows over hard, impervious surfaces, it picks up pollutants.
Some pollutants carried by the water runoff include trash, pet waste, pesticides, fertilizer,
motor oil and more.
Water Conservation
Pollution not only impairs the water quality for habitat and recreation, it can also reduce
the water available for reuse. Runoff allowed to soak into the ground is cleaned as it
percolates through the soil, replenishing depleted groundwater supplies. Groundwater
provides at least 50% of the total water for drinking and other indoor household activities in
north and central Orange County. When land is covered with roads, parking lots, homes,
etc., there is less land to take in the water and more hard surfaces over which the water
can flow.
In Orange County, 60-70% of water used by residents and businesses goes to irrigation
and other outdoor uses. Reusing rainwater to irrigate our lawn not only reduces the impact
of water pollution from runoff, but it also is a great way to conserve our precious water
resources and replenish our groundwater basin.
Permeable pavement allows water runoff to infiltrate through the soil and prevents most pollutants from reaching the storm drain system.
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
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
and reduce the need for potentially harmful pesticides and fertilizer.
Please see the California Friendly Garden Guide produced by the
Metropolitan Water District of Southern California and associated
Southern California Water Agencies for a catalog of California
friendly plants and other garden resources at
www.bewaterwise.com/Gardensoft.
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.
IRRIgATE EFFICIENTLY
Smart Irrigation
Controllers
Smart Irrigation Controllers have internal clocks as well as sensors that will turn off the sprinklers in response to environmental 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.

Do your part to prevent water
pollution in our creeks, rivers, bays
and ocean.
Clean beaches and healthy creeks, rivers,
bays, and ocean are important to Orange
County. However, many common household
activities can lead to
water pollution if you’re
not careful.
Litter, oil, chemicals and
other substances that
are left on your yard or
driveway can be blown
or washed into storm
drains that flow to the
ocean. Over-watering
your lawn and washing
your car can also flush
materials into the storm
drains. Unlike water in sanitary sewers
(from sinks and toilets), water in storm
drains is not treated.
You would never pour soap, fertilizers or oil
into the ocean, so don’t let them enter
streets, gutters or storm drains. Follow the

Household Tips
PA2022-0262
Gardening Activities
�Follow directions on pesticides and
fertilizers, (measure, do not estimate
amounts) and do not use if rain is
predicted within 48 hours.
�Water your lawn and garden by hand to
control the amount of water you use. Set
irrigation systems to reflect seasonal
water needs. If water flows off your yard
and onto your driveway or sidewalk,
your system is over-watering.
�Mulch clippings or leave them on the
lawn. If necessary, dispose in a green
waste container.
�Cultivate your garden often to control
weeds.
Washing and Maintaining Your Car
�Take your car to a commercial car wash
whenever possible.
�Choose soaps, cleaners, or detergents
labeled “non-toxic,” “phosphate free” or
“biodegradable.” Vegetable and citrus-
based products are typically safest for
the environment, but even these should
not be allowed into the storm drain.
�Shake floor mats into a trash can or
vacuum to clean.
�Do not use acid-based wheel cleaners and
“hose off” engine degreasers at home.
They can be used at a commercial facility,
which can properly process the washwater.
�Do not dump washwater onto your
driveway, sidewalk, street, gutter or
storm drain.Excess washwater shouldbe disposed of in the sanitary sewers
(through a sink, or toilet) or onto an
absorbent surface like your lawn.
�Use a nozzle to turn off water when not
actively washing down automobile.
�Monitor vehicles for leaks and place
pans under leaks. Keep your car well
maintained to stop and prevent leaks.
�Use cat litter or other absorbents and
sweep to remove any materials deposited
by vehicles. Contain sweepings anddispose of at a HHWCC.
�Perform automobile repair and
maintenance under a covered area and
use drip pans or plastic sheeting to keep
spills and waste material from reaching
storm drains.
�Never pour oil or antifreeze in thestreet, gutter or storm drains.
Recycle these substances at a service
station, HHWCC, or used oil recycling
center. For the nearest Used Oil
Collection Center call 1-800-CLEANUP

Tips for Pool Maintenance
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.
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.

C 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. Pet
waste and pet care products
can be washed into the
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 put pet
waste or pet care products
into the ocean, so don’t let
them enter the storm drains.
Follow these easy tips to help
prevent water pollution.

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
shampoos can be harmful to marine
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
street, gutter or storm drain.
Flea Control
Consider using oral or topical flea
control products.
If you use flea control products
such as shampoos, sprays or collars,
make sure to dispose of any unused
products at
a Household
Hazardous
Waste
Collection
Center. For
location
information,
call (714) 834-6752.
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.

Tips for Residential
Pool, Landscape and
Hardscape Drains
PA2022-0262
Pool Maintenance
All pool water discharged to the curb, gutter or
permitted pool drain from your property must meet the
following water quality criteria:
The residual chlorine does not exceed
0.1 mg/L (parts per
million).
The pH is between
6.5 and 8.5.
The water is free
of any unusual
coloration.
There is no discharge
of filter media or acid
cleaning wastes.
Some cities have ordinances that do not allow pool
water to be discharged to the storm drain. Check with
your city.
Landscape and
Hardscape Drains
The following recommendations will help reduce or
prevent pollutants from your landscape and hardscape
drains from entering the street, gutter or storm drain.
Unlike water that enters the sewer (from sinks and
toilets), water that enters a landscape or hardscape
drain is not treated before entering our creeks, rivers,
bays and ocean.
Household Activities
Do not rinse spills of materials or chemicals to any
drain.
Use dry cleanup methods such as applying cat
litter or another absorbent material, then sweep it
up and dispose of it in the trash. If the material is
hazardous, dispose of it at a Household Hazardous
Waste Collection Center (HHWCC). For locations,
call (714) 834-6752 or visit www.oclandfills.com.
Do not hose down your driveways, sidewalks or
patios to your landscape or hardscape drain.
Sweep up debris and dispose of it in the trash.
Always pick up after your pet. Flush waste down
the toilet or dispose of it in the trash.
Tips for Residential Pool, Landscape and Hardscape Drains
Do not store items such as cleaners, batteries,
automotive fluids, paint products, TVs, or
computer monitors uncovered outdoors. Take
them to a HHWCC for disposal.
Yard Maintenance
Do not overwater. Water by hand or set
automated irrigation systems to reflect seasonal
water needs.
Follow directions on
pesticides and fertilizers
(measure, do not estimate
amounts) and do not use
if rain is predicted within
48 hours.
Cultivate your garden
often to control weeds
and reduce the need to
use chemicals.
Vehicle Maintenance
Never pour oil or antifreeze down your
landscape or hardscape drain. Recycle these
substances at a service station, a waste collection
center or used oil recycling center. For
locations, contact the Used Oil Program at 1-800-
CLEANUP or visit www.CLEANUP.org.
Whenever possible, take your vehicle to a
commercial car wash.
If you do wash your vehicle at home, do not
allow the washwater to go down your landscape
or hardscape drain. Instead, dispose of it in
the sanitary sewer (a sink or toilet) or onto an
absorbent surface such as your lawn.
Use a spray nozzle that will shut off the water
when not in use.
