II.4 Post Development Drainage Characteristics
Describe post development drainage characteristics. Refer to Section 2.2.4 in the TGD.
Existing land use consists of multiple structures and a parking lot. The existing property is
considered to be nearly all impervious. The proposed development will improve this situation by
providing some landscaped features in common areas and the front of the proposed homes. Overall
peak flows from the property are anticipated to be less than or equal to pre development flows.
In landscaped areas, the use of area drain inlets will be employed to reduce storm water from
transporting sediments over flatwork improvements. Area drains will curb core to adjacent public
streets per public standards.
II.5 Property Ownership/Management
Describe property ownership/management. Refer to Section 2.2.5 in the TGD.
Parcel A of the project site (APN 423-112-02) located at 3303 Via Lido is owned by First Church of

Site Characteristics (continued)
Soil Type, Geology, and
Infiltration Properties
Per the Geotechnical Engineering Services Report, prepared by
Professional Service Industries, Inc. dated August 24, 2012, the
following soil conditions were encountered:
“As indicated on our boring logs, the existing pavement section
generally consists of approximately 3 inches of asphalt underlain by a
silty sand with gravel (apparent base course) that was estimated to be
about 6 inches thick. The pavement section was underlain by native
soil consisting of medium dense silty gravely sand with trace organics
that extend to a depth of approximately 5-feet below existing grade,
very soft to soft clayey silt that extends to a depth of approximately
7½-feet below existing grade, and loose to very dense slightly silty
sand to the maximum depth explored of approximately 50-feet below
the existing ground surface elevation.”
Hydrogeologic
(Groundwater)
Conditions
Per the Geotechnical Engineering Services Report, prepared by
Professional Service Industries, Inc. dated August 24, 2012:
“Groundwater was measured at approximately 5-feet below existing
grade in all four borings at the time of drilling. Based on a review of
the California Geological Survey (CGS) Seismic Hazard Zone Report
for the Newport Quadrangle, the historic high groundwater depth for
the site area is noted to be about 5 feet below grade.
It is possible that seasonal variations (temperature, rainfall, tide
conditions etc) will cause fluctuations in the groundwater level.
Additionally, perched water may be encountered in discontinuous
zones within the overburden. The groundwater levels presented in
this report are the levels that were measured at the time of our field
activities. It is recommended that the contractor determine the actual
groundwater levels at the site at the time of the construction activities
to determine the impact, if any, on the construction procedures.”
Geotechnical Conditions
(relevant to infiltration)
Per the Geotechnical Engineering Services Report, prepared by
Professional Service Industries, Inc. dated August 24, 2012, the
following information was provided in regards to infiltration:
“Note that the upper soils are sensitive to disturbances caused by
construction traffic and to changes in moisture content. During wet
weather periods, increases in the moisture content of the soil can
cause significant reduction in the soil strength and support
capabilities. Furthermore, perched groundwater conditions can
develop during periods of heavy rainfall as a result of less permeable

layers impeding infiltration. In these instances, overlying subgrade
soils may become unstable and require remedial measures. It will,
therefore, be advantageous to perform earthwork and foundation
construction activities during dry weather.”
Off-Site Drainage No off-site drainage was accounted for within this report.
Utility and Infrastructure
Information
No underground storm drain exists directly adjacent to the site. The
proposed development is designed to convey storm water flows
through surface drainage to adjacent public streets or by collection
into small area drain systems on-site which curb core to the adjacent
public streets.

Per 7.II-3.2.2 of the Model WQMP, if the LID performance criteria is not
feasibly met by retention and/or biotreatment, then sizing of onsite
treatment control BMPs are required. Sizing of these treatment control BMPs
will 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 PLAN
The proposed development is located on the Balboa Peninsula, in the City of Newport Beach. The
Pacific Ocean is located about 2,000 feet to the west of the site, and the Newport Bay is located about
170 feet to the east of the site. The topography of the site slopes gently in a northwest direction, at a
rate of no more than a third of a percent.
Underground storm drain facilities do not exist adjacent to the site. Storm water runoff presently
surface flows off the site to the adjacent public streets (Via Lido, Via Oporto and Via Malaga) where
they are collecting in surface gutters and conveyed to the north. From there flows are collecting in an
off‐site catch basin where they empty into the adjacent Newport Bay.
The property is designated in FEMA Flood Zone “X” shaded, areas considered to be outside of the
100‐year floodplain, but inside the 500‐year floodplain.
Typical to the Balboa Peninsula area, groundwater was found at shallow depths (up to five feet from
the surface).
Existing land use consists of multiple structures and a parking lot. The existing property is
considered to be nearly all impervious. The proposed development will improve this situation by
providing some landscaped features in common areas and the front of the proposed homes. Overall
peak flows from the property are anticipated to be less than or equal to pre development flows.
In landscaped areas, the use of area drain inlets will be employed to reduce storm water from
transporting sediments over flatwork improvements. Area drains will curb core to adjacent public
streets per public standards.
Water quality BMPs will be employed per City of Newport Beach Model WQMP requirements.
Hydraulic Conditions of Concern are not anticipated because the proposed development will not be
increasing overall storm water runoff volumes.
Due to the historic groundwater levels, deep infiltration BMPs would not be a feasible on this site.
However, considering the site layout, Hydrologic Source Control (HSC) BMPs were utilized to reduce
the overall design capture volume.

IV.3 LID BMP SELECTION AND PROJECT CONFORMANCE ANALYSIS
IV.3.1 Hydrologic Source Controls
Name Included?
Localized on-lot infiltration
Impervious area dispersion (e.g. roof top
disconnection)
Street trees (canopy interception)
Residential rain barrels (not actively managed)
Green roofs/Brown roofs
Blue roofs
Impervious area reduction (e.g. permeable
pavers, site design)
Impervious Area Dispersion: Impervious area dispersion refers to the practice of routing runoff
from pervious areas, such as rooftops, walkways, and patios onto the surface of adjacent pervious
areas. Runoff is dispersed uniformly via splash block and soaks into the ground as it moves slowly
across the surface of pervious areas. Minor ponding may occur, but it is not the intent of this
practice to actively promote on-lot storage or infiltration. Standing water is not allowed.
Impervious Area Dispersion is ranked second in the preferred method of treatment.
Street Trees: By intercepting rainfall, trees can provide several aesthetic and storm water benefits
including peak flow control, increased infiltration and evapotranspiration, and runoff temperature
reduction. The volume of precipitation intercepted by the canopy reduces the treatment volume
required for downstream treatment BMPs. Shading reduces heat island effect as well as the
temperature of adjacent impervious surfaces, over which storm water flows, and thus reduces the
heat transferred to downstream receiving waters. Tree routes also strengthen the soil structure and
provided infiltration pathways, simultaneously reducing erosion potential and enhancing
infiltration. Street Trees are provided along the private street and near the guest parking areas.
Street Trees are ranked third in the preferred method of treatment.
Impervious Area Reduction: Impervious Area Reduction such as permeable concrete pavements
contain small voids that allow water to pass through to a gravel base. They come in a variety of
forms; they may be modular paving system (concrete pavers, grass-pave, or gravel-pave) or poured
in place pavement (pourous concrete, permeable asphalt). All permeable pavements treat
stormwater and remove sediments and metals to some degree within the pavement pore space and

gravel base. While conventional pavement result in increased rates and volumes of surface runoff,
properly constructed and maintained porous pavements, allow stormwater to percolate through
the pavement and enter the soil below. This facilitates groundwater recharge while providing the
structural and functional features needed for the roadway, parking lot, or sidewalk. The paving
surface, subgrade and installation requirements of permeable pavements are more complex than
those for conventional asphalt or concrete surfaces. For porous pavements to function properly
over an expected life span of 15-20 years, they must be properly sited and carefully designed an
installed, as well as periodically maintained. Failure to protect paved areas from construction-
related sediment loads can result in their premature clogging and failure.

IV.4.1 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.

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.
Clean 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.
Printed on Recycled Paper
Tips for Pool Maintenance
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.
Tips for Projects Using Paint
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:

Special Thanks to
The City of Los Angeles Stormwater Program for the use of its artwork
The Metropolitan Water District of Southern California for the use of the California-
Friendly Plant and Native Habitat photosDid you know that most of the pollution found in our waterways is not from a single source, but from a “non-point” source meaning the accumulation of pollution from residents and businesses throughout the community
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 approximately 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.

However, not properly disposing
of household hazardous waste can
lead to water pollution. Batteries,
electronics, paint, oil, gardening
chemicals, cleaners and other
hazardous materials cannot be
thrown in the trash. They also must
never be poured or thrown into
yards, sidewalks, driveways, gutters

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.
Some types of industrial facilities are required
to obtain coverage under the State General
Industrial Permit. For more information visit:

Printed on Recycled Paper
Tips for Pool Maintenance
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
construction and demolition recycling
locations in your area, visit
www.ciwmb.ca.gov/recycle.
Properly label materials. Familiarize
employees with Material
Safety Data Sheets.
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.
PROJECT
PREVENTION
Proper Maintenance Practices for your Business
Never Dispose
of Anything
in the Storm
Drain.
•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.
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.
Think ahead.

Clean 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.

The Ocean Beginsat Your Front Door
Responsible
Pest Control
Printed on Recycled Paper
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.
Consult with a
Certified Nursery
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.
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.
Apply the pesticide to the pest during its most
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).
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
contaminated materials in a doubled plastic bag.
All materials used to clean up the spill should
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.

Did you know that just
one quart of oil can pollute 250,000
gallons of water?
A clean ocean and healthy creeks, 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 storm drains is
not treated before 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 before delivering your used oil. This
listing of companies is for your reference
and does not constitute a recommendation
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
hazardous 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?
You Are Responsible for a
Sewage Spill Caused by a Blockage
or Break in Your Sewer Lines!
Grease builds up inside and eventually blocks
sewer pipes. Grease gets into the sewer from food
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.
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.
Caution
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
You Could Be Liable
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.
Rev 4/06printed on recycled paper
Common Causes
of Sewage Spills
Overflowing
cleanout pipe
located on
private property
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.
DTP113
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.

Agency Responsibilites
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 .
How You Can
Prevent Sewage Spills
A property owner's sewer pipes are called
service laterals and are connected to larger
local main and regional trunk lines. Service
laterals run from the connection at the
home to the connection with the public
sewer (including the area under the street).
These laterals are the responsibility of the
property owner and must be maintained
by the property owner. Many city agencies
have adopted ordinances requiring
maintenance of service laterals. Check with
your city sewer/local public works
department for more information.
Operation and maintenance of local and
regional sewer lines are the responsi-
bility of the city sewer/public works depart-
ments and public sewer districts.
Preventing
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-
bent waste materials such as paper, coffee grounds, or kitty
litter and place it in the trash. Wipe food scraps from plates
and 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.
!City Sewer/Public Works Departments—

Clean 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.

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.
Fertilizers, pesticides and
other chemicals that are left
on yards or driveways can
be blown or washed into
storm drains that flow to the
ocean. Overwatering lawns
can also send materials into
storm drains. Unlike water
in sanitary sewers (from sinks
and toilets), water in storm
drains is not treated before
entering our waterways.
You would never pour
gardening products into the
ocean, so don’t let them enter
the storm drains. Follow
these easy tips to help prevent
water pollution.
Printed on Recycled Paper
Tips for Landscape and GardeningTips for Landscape & Gardening
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

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 Pet Care
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

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
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
Never allow pollutants to enter the street, gutter or storm drain!
Lawn and Garden

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
Printed on Recycled Paper The Orange County Stormwater Program has created and moderates an electronic mailing list to facilitate communications, take questions and exchange ideas among its users about issues and topics related to stormwater and urban runoff and the implementation of program elements To join the list, please send an email to ocstormwaterinfo-join@list ocwatersheds comOrange County Stormwater Program
Even if you live miles from the Pacific
Ocean, you may be unknowingly
polluting it.
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
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
Dumping one quart of motor oil into a
storm drain can contaminate 250,000
gallons of water.

PROJECT INFORMATION
PROJECT AUTHORIZATION
Professional Service Industries, Inc. (PSI) has completed a geotechnical exploration for the
proposed townhome/condominium development to be located at the NWC of Via Lido and Via
Malaga in Newport Beach, California. The Wieland-Davco Corp. authorized our services on August
7, 2012 by signing PSI proposal 0559-75353 dated August 1, 2012.
PROJECT DESCRIPTION
Mr. Justin Park of the Wieland-Davco Corp. provided the project information as described herein
to PSI. Based on our discussions with Mr. Park and a review of the site plan prepared by Shusin
+ Donaldson Architects, Inc. for 3355 & 3388 Via Lido, we understand that new at-grade two to
three story townhome/condominium buildings and associated improvements are planned to be
constructed at the above mentioned addresses in Newport Beach, California. The site is
presently occupied by commercial retail buildings along Via Lido (to the east) and a parking lot
(to the west). The existing commercial/retail buildings and paving will be demolished to make
way for the planned townhomes/condos to be constructed along the property lines and
driveways and parking to be constructed between the proposed townhomes/condos. A Site
Vicinity Map showing the site location is included as Figure 1 in the Appendix.
Detailed structural loading has not been provided to us, however we were informed that loads for a
3-story wood-framed residential structure on the order of 3 kips per foot for wall footings and 50 kips
for columns would be reasonable assumptions. Detailed grading information has also not been
provided, however, PSI has assumed that the site grading will consist of cuts and fills of less than 3
feet, not including any remedial grading.
The geotechnical recommendations presented in this report are based on the available project
information, site location, laboratory testing, and the subsurface materials. If any of the noted
information is incorrect, please inform PSI in writing so that we may amend the recommendations
presented in this report if appropriate and if desired by the client. PSI will not be responsible for the
implementation of its recommendations when it is not notified of changes in the project.
PURPOSE AND SCOPE OF SERVICES
The purpose of this geotechnical study was to explore the subsurface conditions and provide
suitable foundation recommendations for the proposed construction. The geotechnical
exploration for this project involved drilling four test borings, laboratory testing, and geotechnical
analyses. This report briefly outlines the testing procedures, presents available project
information, describes the site and subsurface conditions, and presents recommendations for
the following:
Site preparation and grading.
Findings pertaining to potentially expansive, deleterious or corrosive materials.
An assessment of the liquefaction potential and an estimate of seismic-induced
settlements
PROPOSED TOWNHOMES / CONDOS PSI REPORT 0559771
NWC VIA LIDO & VIA MALAGA
NEWPORT BEACH, CA
AUGUST 24, 2012
PROFESSIONAL SERVICE INDUSTRIES, INC. PAGE 2
Recommendations pertaining to design and construction of foundations for support of
the proposed construction, including allowable soil bearing pressure, anticipated bearing
depths and estimated settlements.
Pavement recommendations including subgrade preparation and construction control of
groundwater.
Comments regarding factors that may impact construction and performance of the
proposed construction.
The scope of services did not include an environmental assessment for determining the presence
or absence of wetlands, or hazardous or toxic materials in the soil, surface water, groundwater, or
air on or below, or around this site. Any statements in this report or on the boring logs regarding
odors, colors, and unusual or suspicious items or conditions are strictly for informational purposes.
PSI is concurrently performing a Phase I Environmental Site Assessment (ESA) at the subject
site and a separate report will be issued to address environmental concerns.
A geologic fault study to evaluate the possibility of surface faulting at this site was beyond the scope
of this investigation. Should you desire a detailed fault study, please contact us; however, active
faults are not known to exist on or in the immediate vicinity of the site.
Services that investigate or detect the presence of moisture, mold, or other biological contaminants
in or around any structure, or any service that was designed or intended to prevent or lower the risk
of the occurrence of the amplification of the same, were not provided. Mold is ubiquitous to the
environment with mold amplification occurring when building materials are impacted by moisture.
Site conditions are outside of PSI’s control, and mold amplification will likely occur, or continue to
occur, in the presence of moisture. As such, PSI cannot be held responsible for the occurrence or
recurrence of mold amplification.
SITE AND SUBSURFACE CONDITIONS
SITE LOCATION AND DESCRIPTION
The project site is located adjacent to the NWC of Via Lido and Via Malaga in Newport Beach,
California. Furnished information indicates the approximate site GPS coordinates are latitude:
34.6167°N and longitude: -117.9281°W. The subject site is currently developed with existing
commercial/retail buildings along Via Lido (to the east) and a parking lot (to the west. The site is
relatively level with a maximum elevation differential of about 2 feet, sloping down to the west
(Google Earth, 2011). The site is triangular in shape and bounded by Via Lido to the northeast,
Via Malaga to the south and Via Oporto to the west.
REGIONAL GEOLOGY
The subject site is located at elevations between approximately 6 to 8 feet above mean sea level
(Google Earth). Based on a review of the CGS Seismic Hazard Report, Newport Quadrangle,
the site is located within the Orange County coastal plain and underlain by Quaternary alluvial
and fluvial sedimentary deposits.

NWC VIA LIDO & VIA MALAGA
NEWPORT BEACH, CA
AUGUST 24, 2012
PROFESSIONAL SERVICE INDUSTRIES, INC. PAGE 3
REGIONAL SEISMICITY
The project site is located in Southern California, which has undergone a complex multiphase
structural history and remains an active tectonic region with documented historic earthquakes.
Generally, the seismicity within California can be attributed to faulting due to regional tectonic
movement. This includes the San Andreas Fault and other sub-parallel strike-slip faults, as well
as normal and thrust faulting within the State. The area of the subject site is considered
seismically active. Seismic hazards within the site can be attributed to potential ground shaking
resulting from earthquake events along nearby or more distant faulting.
The primary causes of damage in this general area during seismic events include ground
shaking and liquefaction of the subsurface strata. Liquefaction occurs when loose granular and
low plastic materials below the groundwater table are subjected to cyclic shear forces resulting
from seismic events. During seismic shaking the porewater pressure increases with a
corresponding decrease in the soils effective stress. Excess pore pressures ultimately dissipate
and the soil consolidates, often resulting in significant total and differential settlement of the
ground surface.
SUBSURFACE CONDITIONS
The boring locations were marked in the field by a PSI representative by referencing existing
landmarks based on the information provided by the client. A truck-mounted CME-75 drill rig
using mud rotary drilling methods was used to advance the borings. Soil samples were
routinely obtained during the drilling process. Drilling and sampling techniques were
accomplished general in accordance with ASTM procedures (ASTM D1586 and D3550).
The subsurface conditions were explored by drilling four soil borings at this site. Soil borings B1
through B4, were drilled within the existing parking lot to depths ranging from approximately 20
to 50-feet below the existing ground surface elevation. The locations of our test borings were
restricted due to the existing on-site improvements. Figure 2 in the Appendix shows the
approximate boring locations. The soil types encountered at the specific boring locations are
presented on the attached Boring Logs in the Appendix.
As indicated on our boring logs, the existing pavement section generally consists of
approximately 3 inches of asphalt underlain by a silty sand with gravel (apparent base course)
that was estimated to be about 6 inches thick. The pavement section was underlain by native
soil consisting of medium dense silty gravely sand with trace organics that extend to a depth of
approximately 5-feet below existing grade, very soft to soft clayey silt that extends to a depth of
approximately 7½-feet below existing grade, and loose to very dense slightly silty sand to the
maximum depth explored of approximately 50-feet below the existing ground surface elevation.
During the sampling procedure, Standard Penetration Tests (SPT) were performed in
accordance with ASTM D1586 and relatively undisturbed samples were obtained in general
accordance with ASTM D3550. The SPT for soil borings is performed by driving a 2-inch
diameter split-spoon sampler into the undisturbed formation located at the bottom of the
advanced borehole with repeated blows of a 140-pound hammer falling a vertical distance of
30-inches. The number of blows required to drive the sampler the last 12-inches of an 18-inch
penetration depth is a measure of the soil consistency. For ASTM D-3550 (California Modified
PROPOSED TOWNHOMES / CONDOS PSI REPORT 0559771
NWC VIA LIDO & VIA MALAGA
NEWPORT BEACH, CA
AUGUST 24, 2012
PROFESSIONAL SERVICE INDUSTRIES, INC. PAGE 4
Sampler), the split barrel sampler possesses a 3-inch O.D. and is driven in the same manner as
the SPT. The blow count obtained from the California Modified sampler should be reduced by
approximately 40 percent to obtain a rough correlation to SPT blow counts (N-value). Samples
were identified in the field, placed in sealed containers and transported to the laboratory for
further classification and testing.
The stratification presented on the Boring Logs is based on a visual examination of the
recovered soil samples and the interpretation of field logs by a geotechnical professional.
Included on the Boring Logs are the standard penetration resistances (SPT N-values and
California Modified sampler blows) recorded in the individual borings at standard testing
intervals to the boring termination depths.
The above subsurface information is of a generalized nature to highlight the major subsurface
stratification features and material characteristics. The Boring Logs, included in the Appendix,
should be reviewed for specific information at the boring locations. These records include soil
descriptions, stratification, penetration resistance, locations of the samples and laboratory test
data. The stratification shown on the logs represent the conditions only at the actual location at
the time of our exploration. Variations may occur and should be expected between locations.
The stratification that represents the approximate boundary between subsurface materials and
the actual transition may be gradual. Lines of demarcation represent the approximate boundary
between subsurface materials, and the transition may be gradual. It should be noted that,
although the test borings are drilled and sampled by experienced professionals, it is sometimes
difficult to record changes in stratification within narrow limits, especially at great depths. In the
absence of foreign substances, it is also sometimes difficult to distinguish between discolored
soils and clean fill soil.
GROUNDWATER INFORMATION
Groundwater was measured at approximately 5-feet below existing grade in all four borings at the
time of drilling. Based on a review of the California Geological Survey (CGS) Seismic Hazard Zone
Report for the Newport Quadrangle, the historic high groundwater depth for the site area is noted to
be about 5 feet below grade.
It is possible that seasonal variations (temperature, rainfall, tide conditions etc) will cause
fluctuations in the groundwater level. Additionally, perched water may be encountered in
discontinuous zones within the overburden. The groundwater levels presented in this report are the
levels that were measured at the time of our field activities. It is recommended that the contractor
determine the actual groundwater levels at the site at the time of the construction activities to
determine the impact, if any, on the construction procedures.
LABORATORY TESTING
The soil samples obtained during the field exploration were transported to our laboratory and
selected soil samples were tested in the laboratory to determine the material properties for
evaluation. Laboratory testing on selected samples included Moisture Content (ASTM D2216),
Unit Weight, Sieve Analysis (ASTM D422 and D1140), Expansion Index testing (ASTM D4829),
Corrosion testing (CTM 643, CTM 417 and CMT 422), Atterberg Limit testing (ASTM D4318),
and Consolidation (ASTM D2435). Laboratory testing was performed in general accordance
PROPOSED TOWNHOMES / CONDOS PSI REPORT 0559771
NWC VIA LIDO & VIA MALAGA
NEWPORT BEACH, CA
AUGUST 24, 2012
PROFESSIONAL SERVICE INDUSTRIES, INC. PAGE 5
with ASTM and/or California Test procedures. Unless otherwise informed, the soil samples will
be discarded 60 days from the issuance of the report.
Results of our laboratory testing indicate the tested materials have moisture contents between
approximately 3 percent to 54 percent. Consolidation tests were performed on samples at
depths of 7½ feet, 5 feet, and 10 feet below existing grade at Test Boring Nos. 1, 2, and 3,
respectively, and these tests indicated the soils at 7½ feet and 10 feet in Test Borings Nos. 1
and 3, respectively possess a relatively low compressibility. However the consolidation test
performed on the soil sample at 5-feet in Test Boring No. 2 indicated a high level of
compressibility. The corrosion test results indicated the near surface soils are nearly neutral,
have a low chloride content, possess a negligible sulfate exposure and resistivity results
indicates the materials possess a progressively less corrosive environment for ferrous metals.
The results of our Expansion Index testing indicate the near surface soils have a very low
expansion potential (EI=0). Laboratory test data along with detailed descriptions of the soils can
be found on the Boring Logs in the Appendix.
CONCLUSIONS AND RECOMMENDATIONS
GENERAL
.
The following geotechnical design recommendations have been developed on the basis of the
previously described project characteristics and subsurface conditions encountered. If there are
any changes in these project criteria, including building location on the site, PSI should be
contacted to determine if modifications to the recommendations are warranted.
EARTHQUAKE AND SEISMIC DESIGN CONSIDERATIONS
The project site is located within a municipality that employs the 2010 California Building Code
(CBC), the locally adopted version of the International Building Code, 2009 edition. As part of
this code, the design of structures must consider dynamic forces resulting from seismic events.
These forces are dependent upon the magnitude of the earthquake event as well as the
properties of the soils that underlie the site. As part of the procedure to evaluate seismic forces,
the code requires the evaluation of the Seismic Site Class, which categorizes the site based
upon the characteristics of the subsurface profile within the upper 100 feet of the ground
surface. To define the Site Class for this project, we have interpreted the results of soil test
borings drilled within the project site and estimated appropriate soil properties below the base of
the borings to a depth of 100 feet as permitted by the code. The estimated soil properties were
based upon our experience with subsurface conditions in the general site area.
Based upon our evaluation, the subsurface conditions within the site are consistent with the
characteristics of a Site Class “D” as defined in Table 1613.5.2 of the CBC. The associated
USGS-NEHRP (2002) probabilistic ground acceleration values and site coefficients for the
general site area were obtained from the USGS geohazards web page:
http://earthquake.usgs.gov/research/hazmaps/design
Which is presented in Table 1.

Hazard Assessment
Alquist-Priolo Fault Zone - The seismicity of the site was evaluated utilizing deterministic methods
for active faults within the regional vicinity. According to the Alquist-Priolo Special Studies Zones
Act of 1972 (revised 1994) faults have been classified as active faults which show apparent
movement during the last 11,000 years (i.e., Holocene time). The site is not located within a
currently designated Earthquake Fault Zone per the Alquist-Priolo Special Studies Zone Map
produced by the California Geological Survey (CGS). The nearest zoned active fault is the
Newport – Inglewood (L.A. Basin) Fault Zone, mapped 0.4 mile to the northwest of the subject site.
Lurching and Shallow Ground Rupture – Breaking of the ground because of active faulting is not
likely due to the absence of known active fault traces within the project limits.
Liquefaction Induced Settlement - Liquefaction and seismically induced settlement typically occur in
loose granular and low-plastic silt and clay soils with groundwater near the ground surface. During
an earthquake, ground shaking causes the soil to consolidate and an increase in the pore
pressures in saturated soils. After dissipation of the excess pore pressures, the saturated soils tend
to settle. Fine-grained plastic soils are generally not susceptible to liquefaction or to short-term
settlement due to seismic loads.
According to the California Geological Survey (CGS) Newport 7.5’ Quadrangle hazard map, the
subject site is located within an area that is classified as being susceptible to liquefaction and
has a historic high groundwater depth of approximately 5 feet below existing ground surface
elevation. Our borings indicate depth to groundwater was measured to be at an approximate depth
of 5 feet after drilling was completed.
In order to evaluate the potential for soil liquefaction at this site, we performed an analysis utilizing
the LIQUEFYPRO computer software program. For this analysis, we used a groundwater depth of
PROPOSED TOWNHOMES / CONDOS PSI REPORT 0559771

NEWPORT BEACH, CA
AUGUST 24, 2012
PROFESSIONAL SERVICE INDUSTRIES, INC. PAGE 7
5 feet (historic high), the soil profile identified in Boring B-1 and a ground acceleration of 0.5g
(SDS/2.5, as per the CBC).The results of our analysis indicates that localized zones of the silty sand
soils are potentially susceptible to liquefaction upon application of the design site acceleration. Our
analysis indicates that the sandy soils between about 7½ to 10 feet, 26 to 28 feet, and 29 to 30 feet
below grade are potentially susceptible to liquefaction upon application of the design earthquake.
The most significant effect of soil liquefaction is expected to be ground surface settlement resulting
from volumetric strain within the liquefiable soils. Based on our analysis, we estimate a maximum
total seismic induced settlement of approximately 1-¼ inches with an estimated ⅔ inch of
differential settlement across a 40 foot span. Based on this magnitude of estimated settlement, it is
our opinion that mitigation of the liquefaction potential is not warranted. The output file from the
analysis is provided within the Appendix.
Landsliding – Due to the generally flat nature of the site and surrounding properties, it is our opinion
that the site has a low susceptibility to landslides.
Tsunamis and Seiches – Based on our review of the Tsunami Inundation Map for Emergency
Planning, Newport Beach Quadrangle, dated March 15, 2009, issued by the State of California-
Orange County, the site is located within a designated tsunami inundation area. As such the
potential does exist for tsunami inundation to impact the site.
For Seismic Design Category designations of C, D, E or F, which are contingent on the
structures “Seismic Use Group”, the code requires an assessment of slope stability, liquefaction
potential and surface rupture due to faulting or lateral spreading. Detailed evaluations of these
factors were beyond the scope of this study. However, the following table presents a qualitative
assessment of these issues considering the site class, the subsurface soil properties, the
groundwater elevation and probabilistic ground motions.
Table 2: Qualitative Seismic Site Assessments
Hazard Relative Risk Comments
Liquefaction Moderate Differential seismic induced settlement of about ⅔ inch is
estimated across a 40 foot span.
Slope Stability Low Based on the presumed grading plans, significant cut or
fill slopes are not planned for construction.
Surface Rupture Low Active faults are not known to underlie the site.
SITE PREPARATION & GRADING
The current geotechnical issues at the site that will affect the construction of the proposed
development include the following:
1. Surface and subsurface disturbance during clearing and demolition operations.
2. Shallow groundwater.
3. Potentially liquefiable soils.
4. Soft soil deposits which will require the use of a deep foundation system.

PROFESSIONAL SERVICE INDUSTRIES, INC. PAGE 8
Site Preparation
Initial site preparation should include stripping of any vegetation, demolition of the existing
buildings and removal of the existing pavement that is present within the planned new
development areas. Demolition of the existing buildings should include removal of all shallow
foundations, floor slabs and underground construction. Existing underground utilities should
either be properly capped off at the property boundaries and removed or be re-routed around
the new development. Utilities should be removed and properly abandoned in accordance with
local regulatory requirements. All soils disturbed by the clearing and demolition operations
should be removed, cleaned of deleterious materials and stockpiled on-site for future use as
Engineered Fill. All debris and deleterious materials generated by the site stripping and
demolition operations should be legally disposed off-site. If the existing buildings are supported
by deep foundations, we recommend that the deep foundations be cut-off at least 3 feet below
finished grade and to a depth where they will not impact construction of the new foundations.
If grading occurs in the winter rainy season, unstable subgrade conditions may be present.
These conditions may require stabilizing the subgrade with admixtures, such as cement kiln
dust or a coarse aggregate. Isolated areas may be stabilized using a geogrid, such as Tensar
TX160 or equal, with one foot compacted Class II aggregate base over the geogrid. Additional
recommendations can be provided, as required, during construction.
Remedial Grading
Following site clearing, demolition and lowering of site grades where needed, we recommend that
the soils beneath the new buildings be over-excavated to a depth of at least two feet below existing
or finished grade, whichever is deeper. The exposed soils should then be scarified to a depth of
approximately 12 inches, be moisture conditioned to about 0 to 3 percent above the soil’s optimum
moisture content and then be compacted to at least 90 percent of the soil’s maximum dry density,
per ASTM D-1557.
The subgrade within all other development areas of site should be proof rolled with a heavy rubber-
tired piece of construction equipment approved by and in the presence of the Geotechnical
Engineer. Any soil that ruts or excessively deflects during proof rolling should be removed or
stabilized as recommended by the Geotechnical Engineer. Due to the presence of shallow
groundwater, some unstable soil requiring removal or stabilization should be expected. The soils
exposed at the base of all excavations should be scarified to a depth of at least 12 inches, be
moisture conditioned to about 0 to 3 percent above the soil’s optimum moisture and compacted to
at least 90 percent of the soil’s maximum dry density, per ASTM D-1557. However, the top 12-
inches of the pavement subgrade should be compacted to at least 95 percent of the modified
Proctor value (ASTM D-1557).
Site grades may then be raised with low expansive Engineered Fill to achieve the design elevations
at the site. A PSI representative should be on-site during site grading to evaluate the degree of
compaction obtained by the contractor.
Engineered Fill
Engineered Fill material beneath the proposed exterior slabs to support the generators should

AUGUST 24, 2012
PROFESSIONAL SERVICE INDUSTRIES, INC. PAGE 9
not contain rocks greater than 3-inches in diameter or greater than 30 percent retained on the
¾-inch sieve, and should not contain more than 3 percent (by weight) of organic matter or other
unsuitable material. The Expansion Index (EI) for the material should not exceed 40. Based on
our subsurface investigation, existing on-site sandy soils are generally suitable for use as
Engineered Fill; however, this should be confirmed by a PSI representative during grading.
Import materials meeting the above requirements should be approved by the Geotechnical
Engineer prior to use as Engineered Fill. The on-site clayey silt soils are not considered suitable
for use as Engineered Fill beneath surface improvements.
Engineered Fill should be compacted to at least 90 percent of the maximum dry density as
determined by the modified Proctor (ASTM D1557). The moisture content of Engineered Fill
should be maintained at approximately 0 to 3 percent above the material’s optimum moisture
content as determined by the same index during compaction. If the Engineered Fill is too dry,
water should be uniformly applied across the affected fill area. If the Engineered Fill is too wet,
it must be dried. In either event, the Engineered Fill should be thoroughly mixed by disking to
obtain relatively uniform moisture content throughout the lift immediately prior to compaction.
Engineered Fill should be placed in maximum lifts of 8-inches of loose material. Each lift of
Engineered Fill should be tested by a PSI soils technician, working under the direction of our
Project Geotechnical Engineer, prior to placement of subsequent lifts.
Compaction of the backfill should be checked with a sufficient number of density tests by a
representative of the Geotechnical Engineer to determine if adequate compaction is being
achieved by the contractor. The properly compacted Engineered Fill should extend horizontally
outward beyond the exterior perimeter of the foundations a distance equal to the height of fill or
5-feet, whichever is greater, prior to significant sloping.
TEMPORARY EXCAVATION CONSIDERATIONS
In Federal Register Volume 54, No. 209 (October, 1989), the United States Department of
Labor, Occupational Safety and Health Administration (OSHA) amended its "Construction
Standards for Excavations, 29 CFR, Part 1926, Subpart P." This document was issued to
insure better the safety of workers entering trenches or excavations. It is mandated by this
federal regulation that all excavations, whether they be utility trenches, basement excavations,
or footing excavations, be construction in accordance with the reviewed OSHA guidelines. It is
our understanding that these regulations are being strictly enforced and if they are not closely
followed, the owner and the contractor could be liable for substantial penalties.
The contractor is solely responsible for designing and constructing stable, temporary
excavations and should shore, slope, or bench the sides of the excavations as required to
maintain stability of both the excavation sides and bottom. The contractor's responsible person,
as defined in 29 CFR Part 1926, should evaluate the soil exposed in the excavations as part of
the contractor's safety procedures. In no case should slope height, slope inclination, or
excavation depth, including utility trench excavation depth, exceed those specified in local,
state, and federal safety regulations.
We are providing this information solely as a service to our client. PSI is not assuming
responsibility for construction site safety or the contractor’s activities; such responsibility is not

being implied and should not be inferred.
DEEP FOUNDATIONS
Due to the presence of the soft and compressible soils at a depth of about 5 feet below grade
and the shallow water table, it is our opinion that the proposed buildings should be supported by
a deep foundation system that extends through the soft soil deposits and the potentially
liquefiable soils and be supported within the underlying medium dense to dense sandy soil
deposits. The deep foundation system may consist of cast in-place drilled piers (CIDH), driven
pile, auger-cast piles or other propriety systems. We are providing recommendations for CIDH
but other systems can be used and PSI can provide supplemental recommendations as
needed. CIDH should possess a minimum diameter of 24 inches.
Our analysis included a factor of safety of 2 for skin friction and 3 for end bearing. In our analysis,
we conservatively assumed that the soils to a depth of 10 feet had no load-carrying capacity (skin
friction of zero). Additionally, drag load (negative skin friction) resulting from potential soil
liquefaction has been included in the CIDH capacities provided below.
Based on our analysis, we anticipate that the drilled piers will have the allowable axial capacities as
indicated on the following Table 3 for the various pile lengths noted.

*Minimum depth of 15 feet recommended
CIDH may be installed on a spacing of 3 pier diameters (center to center) with no reduction in
capacity for group effects. CIDH capacities for compressive and uplift loading may be increased
by ⅓ for temporary wind and/or seismic loading conditions.
For uplift resistance, we recommend the capacity be based on an average allowable unit skin
friction value of 500 psf within the soils below a depth of 10 feet. The upper 10 feet of soil
should be neglected in calculating the uplift resistance.
We estimate settlement at the base of the CIDH for the design load will be less than ⅔ inch.

PROFESSIONAL SERVICE INDUSTRIES, INC. PAGE 11
Detailed inspection of CIDH construction should be made to verify that the CIDHs are vertical and
founded in the proper bearing stratum, and to verify that all loose materials have been removed
prior to concrete placement. Due to the presence of shallow groundwater and sandy soils,
temporary casing is recommended to limit sloughing of soil and groundwater intrusion into the
drilled shafts. Any accumulated water must be removed prior to the placement of concrete. A
hopper and tremie should be utilized during concrete placement to control the maximum free fall of
the wet concrete to less than five feet unless the mix is designed so that it does not segregate
during free fall and provided the pier excavation is dry. Temporary casing may be removed as the
concrete is placed into the drilled shaft keeping a concrete head of at least two feet above the
bottom of the casing as it is being removed.
Shafts should be clean and be free of all loose materials prior to placement of concrete. The drilled
shafts should be installed in accordance with the guidelines provided in FHWA-IF-99-025. A PSI
representative should verify the bearing stratum, bearing depth, bearing soil condition, and bearing
area and that the pier installation procedures meet the specifications.
LATERAL CAPACITIES
To assess the deflection, moment and shear capacity of the CIDH piers, the computer software
program L-Pile by Ensoft, Inc. was utilized. The analyses were performed for a 24 inch diameter
CIDH pier for varying lengths. For the analyses, the bottom of the pile cap was assumed to be
at finished grade (no pile cap). Lateral capacities were developed for both free and fixed-head
pile conditions. In our analysis, we assumed the soil within the upper 10 feet of grade will have
no lateral support capacity. The computer output files for those analyses are included within the
Appendix. Once the specific foundation type, dimensions and structural detailing is known, the
lateral pile capacities can be re-evaluated.
INTERIOR FLOOR SLABS
The proposed structures may incorporate a conventional slab-on-grade provided the subgrade
is prepared as previously recommended. The on-grade floor slabs should be supported on
Engineered Fill. Soft or otherwise unsuitable areas observed should be addressed on a case-
by-case basis by our Geotechnical Engineer. Although the slab thickness and steel
reinforcement should be determined by the structural engineer, we recommend the floor slab
possess a minimum thickness of 5 inches.
Where concrete slabs are designed as beams on an elastic foundation, the subgrade should be
assumed to have a modulus of subgrade reaction (k-value) of 150 pounds per cubic inch (pci),
based on a one foot square plate bearing test. Dependent on how the floor slab load is applied,
the above subgrade modulus value may need to be geometrically adjusted.
If reducing moisture vapor transmission is a design consideration, we would recommend a
vapor retarding membrane be included in the design. Membrane specification should be
provided by manufacturer. Vapor retarders should be installed in accordance with ACI 302.1,
Chapter 3. A capillary break material (sand) should be provided beneath the vapor retarder.
The precautions listed below should be followed closely for construction of all slabs-on-grade.
These details will not reduce the amount of movement, but are intended to reduce potential

AUGUST 24, 2012
PROFESSIONAL SERVICE INDUSTRIES, INC. PAGE 12
damage should some settlement of the supporting subgrade take place.
Cracking of slabs-on-grade is normal and should be expected. Cracking can occur not
only because of heaving or compression of the supporting soil, but also because of
concrete curing stresses. The occurrence of concrete shrinkage cracks, and problems
associated with concrete curing may be reduced and/or controlled by limiting the
water/cement ratio of the concrete, proper concrete placement, finishing, and curing, and
by the placement of crack control joints at frequent intervals, particularly, where re-entrant
slab corners occur. The American Concrete Institute (ACI) recommends a maximum panel
size (in feet) equal to approximately three times the thickness of the slab (in inches) in both
directions. For example, joints are recommended at a maximum spacing of 12 feet,
assuming a four-inch thick slab. We recommend also that control joints be scored three
feet in from, and parallel to, the foundation walls. Using fiber reinforcement in the concrete
can also control shrinkage cracking.
Some increase in moisture content is inevitable because of development and associated
landscaping. However, extreme moisture content increases can be largely controlled by
proper and responsible site drainage, building maintenance and irrigation practices.
Exterior slabs should be isolated from the building. These slabs should be reinforced to
function as independent units. Movement of these slabs should not be transmitted to the
building foundation or superstructure.
PAVEMENT DESIGN
The recommended thicknesses presented below are considered typical and minimum for the
assumed parameters. We understand that budgetary considerations sometimes warrant thinner
pavement sections than those presented. However, the client, the owner, and the project
principals should be aware that thinner pavement sections might result in increased
maintenance costs and lower than anticipated pavement life.
In designing the proposed paved areas, the existing subgrade conditions must be considered
together with the expected traffic use and loading conditions.
The conditions that will influence the pavement design can be summarized as follows:
1) Subgrade support characteristics of the subgrade. This is typically represented by a R-
Value for the design of flexible pavements in this region.
2) Vehicular traffic, in terms of the number and frequency of vehicles and their range of axle
loads.
3) Probable increase in vehicular use over the life of the pavement.
We recommend that the exposed subgrade be prepared in accordance with the site preparation
requirements specified previously in this report. The upper one foot of pavement subgrade
should be compacted to at least 95 percent of the maximum dry density as determined by the
modified Proctor (ASTM D1557). The fill moisture content at the time of compaction should be
within 1 to 3 percent above the optimum moisture content value. Undercut soil should be

replaced by Engineered Fill.
The appropriate pavement section depends primarily upon the type of subgrade soil, shear
strength, traffic load, and planned pavement life. For preliminary purposes, we have assumed
Traffic Indices of TI=5.0 for parking areas and TI=6.5 for those driveway and truck lanes subject
to relatively heavy traffic. These assumed traffic indices should be verified by the project civil
engineer prior to construction. Based on the soils encountered within our test borings, we have
assumed an R-value of 30 for the near-surface soils within pavement areas. Since an evaluation
of the characteristics of the actual soils at pavement subgrade can only be provided at the
completion of grading, the following pavement sections should be used for planning purposes
only. Final pavement designs should be evaluated after R-value tests have been performed on
the actual subgrade material.
It should be noted that additional earthwork and/or ground improvement efforts may be required
during grading on the actual subgrade material, in order to achieve the aforementioned design
parameters and assumptions. These design thicknesses assume that a properly prepared
subgrade has been achieved.

Concrete pavement is recommended in areas that receive continuous repetitive traffic such as
loading areas and parking lot entrances. Due to heavy wheel loads and impact loads, concrete
approach aprons and dumpster pads, should have a minimum thickness of 6 inches, with an
underlying 4-inch thick section of Class II Aggregate Base (AB). Portland Cement Concrete
pavement sections should incorporate appropriate steel reinforcement and crack control joints
as designed by the project structural engineer. We recommend that sections be as nearly
squared as possible and no more than 15-feet on a side. A minimum 3,500 psi mix is
recommended. The actual design should also be in accordance with design criteria specified by
the governing jurisdiction.
Asphalt Concrete (AC), Portland Cement Concrete, and Class II aggregate base should
conform to and be placed in accordance with the latest revision of the California Department of
Transportation Standard Specifications and American Concrete Institute (ACI) codes. Aggregate
base should be compacted to a minimum of 95 percent of the maximum dry density as
determined by the modified Proctor (ASTM D1557) prior to placement of AC. Subgrade
preparation for pavement areas is included in the Site Preparation section of this report.

CONSTRUCTION CONSIDERATIONS
Moisture Sensitive Soils/Weather Related Concerns
Note that the upper soils are sensitive to disturbances caused by construction traffic and to
changes in moisture content. During wet weather periods, increases in the moisture content of
the soil can cause significant reduction in the soil strength and support capabilities.
Furthermore, perched groundwater conditions can develop during periods of heavy rainfall as a
result of less permeable layers impeding infiltration. In these instances, overlying subgrade
soils may become unstable and require remedial measures. It will, therefore, be advantageous
to perform earthwork and foundation construction activities during dry weather.
Groundwater was measured to be approximately 5-feet below existing ground surface elevation.
It should be noted, however, that variations in the groundwater table may result from fluctuation
in the ground surface topography, subsurface stratification, precipitation, irrigation, and other
factors that may not have evident at the time of our exploration. This sometimes occurs where
relatively impermeable and/or cemented materials are overlain by fill soils. We recommend that
a representative of PSI be present during grading operations to evaluate areas of seepage.
Drainage devices for reduction of water accumulation can be recommended if these conditions
occur.
Water should not be allowed to collect in the foundation excavation, on floor slab areas, or on
prepared subgrades of the construction area either during or after construction. Undercut or
excavated areas should be sloped toward one corner to facilitate removal of any collected
rainwater, groundwater, or surface runoff. Positive site drainage should be provided to reduce
infiltration of surface water around the perimeter of the building and beneath the floor slabs.
The grades should be sloped away from the building and surface drainage should be collected
and discharged such that water is not permitted to infiltrate the backfill and floor slab areas of
the building.
Corrosive Soil Concerns
The corrosive testing on a representative sample of the site soils indicates that the soils
possess a negligible sulfate exposure. Based on this result, it is our opinion that special sulfate-
resistant concrete mix designs are not warranted and Type II cement may be used. Additional
testing should be performed during site grading to assess the sulfate content of the as-graded
soils.
The resistivity results indicate a progressively less corrosive environment for metal pipes. We
suggest that a corrosion engineer be consulted to determine what corrosion protection may be
warranted at this site.
PLAN REVIEW
Once final design plans and specifications are available, a review of grading and foundation plans
by PSI is recommended as a means to check that the evaluations made in preparation of this report
are correct and that earthwork and foundation recommendations have been properly interpreted
and implemented.

OBSERVATION AND TESTING DURING CONSTRUCTION
It is recommended that PSI be retained to provide observation and testing services during for newly
proposed construction. This is to observe compliance with the design concepts, specifications and
recommendations, and to allow for possible changes in the event that subsurface conditions differ
from those anticipated prior to the start of construction.
REPORT LIMITATIONS
The proposed professional services have been performed, findings obtained, and
recommendations prepared in accordance with generally accepted geotechnical engineering
principles and practices at the time of this report. PSI is not responsible for the conclusions,
opinions, or recommendations made by others based on this data. No other warranties are
implied or expressed. The Wieland-Davco Corp., its subsidiaries and affiliates can rely upon
the report under the same terms as if it was originally prepared for them.
The scope of exploration was intended to evaluate soil conditions within the influence of the
proposed foundations. The analyses and recommendations submitted in this report are based
upon the data obtained from the soil borings performed at the locations indicated. If any subsoil
variations become evident during the course of this project, a re-evaluation of the
recommendations contained in this report will be necessary after we have had an opportunity to
observe the characteristics of the conditions encountered. The applicability of the report should
also be reviewed in the event significant changes occur in the design, nature, or location of the
proposed improvements.
