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

Currently the county does not require any permits for rainwater barrels/tanks.
Manufacturer’s instructions
1.) Prepare a reinforced concrete pad that is level and greater than the footprint of the tank;
another option is to prepare an earth ring greater than the footprint of the tank so that no
part of the tank is bearing on the wall. Fill is to be consolidated material with 2 to 3 inches of
sand or gravel on the top surface.
2.) Locate your water tank near an existing downpipe/downspout (refer to TANK
ORIENTATION illustration). Your diverter kit comes with pre-fitted sections of pipe (six feet
long). Therefore, the tank inlet should be within a six-foot radius from the downpipe.
3.) The tank is moved into position. If positioning requires a crane or other equipment, this cost
is at the purchaser’s expense.
4.) The tank must be tied down to prevent it from being blown away. Adding an inch or tow of
water in the tank will help keep it secure.

Non‐Structural Source Control BMPs
TECHNICAL GUIDANCE DOCUMENT
6-1 December 20, 2013
SECTION 6. SOURCE CONTROL MEASURES
This section provides guidance on the selection and design of structural source control
measures.
6.1. Introduction
Source Control BMPs reduce the potential for stormwater runoff and pollutants from coming
into contact with one another. Source Control BMPs are defined as any administrative action,
design of a structural facility, usage of alternative materials, and operation, maintenance,
inspection, and compliance of an area to eliminate or reduce stormwater pollution. Each new
development and significant redevelopment project is required to implement appropriate
Source Control BMP(s) pursuant to Section 2.4.5 of the Model WQMP.
Applicable Source Control BMPs (which includes subcategories of routine non-structural BMPs,
routine structural BMPs and BMPs for individual categories/project features) are required to be
incorporated into all new development and significant redevelopment projects regardless of
their priority, including those identified in an applicable regional or watershed program, unless
they do not apply due to the project characteristics. California Stormwater Quality Association
(CASQA) BMP Fact Sheet numbers are included in parentheses where applicable.
6.2. Non-Structural Measures
N1 Education for Property Owners, Tenants and Occupants
For developments with no Property Owners Association (POA) or with POAs of less than fifty
(50) dwelling units, practical information materials will be provided to the first
residents/occupants/tenants on general housekeeping practices that contribute to the
protection of stormwater quality. These materials will be initially developed and provided to
first residents/occupants/tenants by the developer. Thereafter such materials will be available
through the Permittees’ education program. Different materials for residential, office
commercial, retail commercial, vehicle-related commercial and industrial uses will be
developed.
For developments with POA and residential projects of more than fifty (50) dwelling units,
project conditions of approval will require that the POA periodically provide environmental
awareness education materials, made available by the municipalities, to all of its members.
Among other things, these materials will describe the use of chemicals (including household
type) that should be limited to the property, with no discharge of wastes via hosing or other
direct discharge to gutters, catch basins and storm drains. Educational materials available from
the County of Orange can be downloaded here:
http://www.ocwatersheds.com/PublicEd/resources/default.aspx
TECHNICAL GUIDANCE DOCUMENT
6-2 December 20, 2013
N2 Activity Restrictions
If a POA is formed, conditions, covenants and restrictions (CCRs) must be prepared by the
developer for the purpose of surface water quality protection. An example would be not
allowing car washing outside of established community car wash areas in multi-unit complexes.
Alternatively, use restrictions may be developed by a building operator through lease terms,
etc. These restrictions must be included in the Project WQMP.
N3 (SC-73) Common Area Landscape Management
Identify on-going landscape maintenance requirements that are consistent with those in the
County Water Conservation Resolution (or city equivalent) that include fertilizer and/or
pesticide usage consistent with Management Guidelines for Use of Fertilizers (DAMP Section
5.5). Statements regarding the specific applicable guidelines must be included in the Project
WQMP.
N4 BMP Maintenance
The Project WQMP shall identify responsibility for implementation of each non-structural BMP
and scheduled cleaning and/or maintenance of all structural BMP facilities.
N5 Title 22 CCR Compliance
Compliance with Title 22 of the California Code of Regulations (CCR) and relevant sections of
the California Health & Safety Code regarding hazardous waste management is enforced by
County Environmental Health on behalf of the State. The Project WQMP must describe how the
development will comply with the applicable hazardous waste management section(s) of Title
22.
N6 Local Water Quality Permit Compliance
The Permittees, under the Water Quality Ordinance, may issue permits to ensure clean
stormwater discharges from fuel dispensing areas and other areas of concern to public
properties.
N7 (SC-11) Spill Contingency Plan
A Spill Contingency Plan is prepared by building operator or occupants for use by specified
types of building or suite occupancies. The Spill Contingency Plan describes how the occupants
will prepare for and respond to spills of hazardous materials. Plans typically describe
stockpiling of cleanup materials, notification of responsible agencies, disposal of cleanup
materials, documentation, etc.
N8 Underground Storage Tank Compliance
Compliance with State regulations dealing with underground storage tanks, enforced by
County Environmental Health on behalf of State.
TECHNICAL GUIDANCE DOCUMENT
6-3 December 20, 2013
N9 Hazardous Materials Disclosure Compliance
Compliance with Permittee ordinances typically enforced by respective fire protection agencies
for the management of hazardous materials. The Orange County, health care agencies, and/or
other appropriate agencies (i.e., Department of Toxics Substances Control) are typically
responsible for enforcing hazardous materials and hazardous waste handling and disposal
regulations.
N10 Uniform Fire Code Implementation
Compliance with Article 80 of the Uniform Fire Code enforced by fire protection agency.
N11 (SC-60) Common Area Litter Control
For industrial/commercial developments and for developments with POAs, the owner/POA
should be required to implement trash management and litter control procedures in the
common areas aimed at reducing pollution of drainage water. The owner/POA may contract
with their landscape maintenance firms to provide this service during regularly scheduled
maintenance, which should consist of litter patrol, emptying of trash receptacles in common
areas, and noting trash disposal violations by tenants/homeowners or businesses and reporting
the violations to the owner/POA for investigation.
N12 Employee Training
Education program (see N1) as it would apply to future employees of individual businesses.
Developer either prepares manual(s) for initial purchasers of business site or for development
that is constructed for an unspecified use makes commitment on behalf of POA or future
business owner to prepare. An example would be training on the proper storage and use of
fertilizers and pesticides, or training on the implementation of hazardous spill contingency
plans.
N13 (SD-31) Housekeeping of Loading Docks
Loading docks typically found at large retail and warehouse-type commercial and industrial
facilities should be kept in a clean and orderly condition through a regular program of
sweeping and litter control and immediate cleanup of spills and broken containers. Cleanup
procedures should minimize or eliminate the use of water if plumed to the storm sewer. If wash
water is used, it must be disposed of in an approved manner and not discharged to the storm
drain system. If there are no other alternatives, discharge of non-stormwater flow to the sanitary
sewer must be at an acceptable discharge point such as a cleanout, oil/water separator, grease
interceptor, or industrial sewer connection. All sewer discharges shall be in accordance with
the Orange County Sanitation District’s Wastewater Discharge Regulations and/or Washwater
Disposal Guidelines.
.
TECHNICAL GUIDANCE DOCUMENT
6-4 December 20, 2013
N14 (SC-74) Common Area Catch Basin Inspection
For industrial/commercial developments and for developments with privately maintained
drainage systems, the owner is required to have at least 80 percent of drainage facilities
inspected, cleaned and maintained on an annual basis with 100 percent of the facilities included
in a two-year period. Cleaning should take place in the late summer/early fall prior to the start
of the rainy season. Drainage facilities include catch basins (storm drain inlets) detention basins,
retention basins, sediment basins, open drainage channels and lift stations. Records should be
kept to document the annual maintenance.
N15 (SC-43, SC-70) Street Sweeping Private Streets and Parking Lots
Streets and parking lots are required to be swept prior to the storm season, in late summer or
early fall, prior to the start of the rainy season or equivalent as required by the governing
jurisdiction.
N16 (SD-30, SC-20) Retail Gasoline Outlets
Retail gasoline outlets (RGOs) are required to follow the guidelines of this TGD and Model
WQMP and non-structural source control operations and maintenance BMPs shown in the
CASQA Structural Source Control Fact Sheet SD-30, and Non-structural Source Control Fact
Sheet (SC-20).
Other Non-structural Measures for Public Agency Projects
As required by the Model WQMP other non-structural measures shall be implemented and
included in the Project WQMP as applicable for new public agency Priority Projects as
described in the Municipal Activity fact sheets
http://www.ocwatersheds.com/MunicipalActivities.aspx. These include BMPs FF-1 through
FF-13 for Fixed Facilities and DF-1 for Drainage Facilities. These are listed in Section 6.4, below.
6.3. Structural Measures
The following measures are applicable to all project types. CASQA BMP Fact Sheet numbers are
included in parentheses where applicable; these fact sheets provide further detail on these
BMPs.
S1 (SD-13) Provide Storm Drain System Stenciling and Signage
Storm drain stencils are highly visible source control messages, typically placed directly
adjacent to storm drain inlets. The stencils contain a brief statement that prohibits the dumping
of improper materials into the municipal storm drain system. Graphical icons, either illustrating
anti-dumping symbols or images of receiving water fauna, are effective supplements to the anti-
dumping message. Stencils and signs alert the public to the destination of pollutants discharged
into stormwater. The following requirements should be included in the project design and
shown on the project plans:
Drainage System Maintenance SC-74
January 2003 California Stormwater BMP Handbook 1 of 9
Municipal
www.cabmphandbooks.com
Description
As a consequence of its function, the stormwater conveyance
system collects and transports urban runoff that may contain
certain pollutants. Maintaining catch basins, stormwater inlets,
and other stormwater conveyance structures on a regular basis
will remove pollutants, prevent clogging of the downstream
conveyance system, restore catch basins’ sediment trapping
capacity, and ensure the system functions properly hydraulically
to avoid flooding.
Approach
Suggested Protocols
Catch Basins/Inlet Structures
Municipal staff should regularly inspect facilities to ensure
the following:
- Immediate repair of any deterioration threatening
structural integrity.
- Cleaning before the sump is 40% full. Catch basins
should be cleaned as frequently as needed to meet this
standard.
- Stenciling of catch basins and inlets (see SC-75 Waste
Handling and Disposal).
Clean catch basins, storm drain inlets, and other conveyance
structures in high pollutant load areas just before the wet
season to remove sediments and debris accumulated during
the summer.

Municipal
www.cabmphandbooks.com
Conduct inspections more frequently during the wet season for problem areas where
sediment or trash accumulates more often. Clean and repair as needed.
Keep accurate logs of the number of catch basins cleaned.
Record the amount of waste collected.
Store wastes collected from cleaning activities of the drainage system in appropriate
containers or temporary storage sites in a manner that prevents discharge to the storm
drain.
Dewater the wastes with outflow into the sanitary sewer if permitted. Water should be
treated with an appropriate filtering device prior to discharge to the sanitary sewer. If
discharge to the sanitary sewer is not allowed, water should be pumped or vacuumed to a
tank and properly disposed of. Do not dewater near a storm drain or stream.
Except for small communities with relatively few catch basins that may be cleaned manually,
most municipalities will require mechanical cleaners such as eductors, vacuums, or bucket
loaders.
Storm Drain Conveyance System
Locate reaches of storm drain with deposit problems and develop a flushing schedule that
keeps the pipe clear of excessive buildup.
Collect flushed effluent and pump to the sanitary sewer for treatment.
Pump Stations
Clean all storm drain pump stations prior to the wet season to remove silt and trash.
Do not allow discharge from cleaning a storm drain pump station or other facility to reach
the storm drain system.
Conduct quarterly routine maintenance at each pump station.
Inspect, clean, and repair as necessary all outlet structures prior to the wet season.
Sample collected sediments to determine if landfill disposal is possible, or illegal discharges
in the watershed are occurring.
Open Channel
Consider modification of storm channel characteristics to improve channel hydraulics, to
increase pollutant removals, and to enhance channel/creek aesthetic and habitat value.
Conduct channel modification/improvement in accordance with existing laws. Any person,
government agency, or public utility proposing an activity that will change the natural
(emphasis added) state of any river, stream, or lake in California, must enter into a steam or
Lake Alteration Agreement with the Department of Fish and Game. The developer-applicant
should also contact local governments (city, county, special districts), other state agencies

Illicit Connections and Discharges
During routine maintenance of conveyance system and drainage structures field staff should
look for evidence of illegal discharges or illicit connections:
- Is there evidence of spills such as paints, discoloring, etc.
- Are there any odors associated with the drainage system
- Record locations of apparent illegal discharges/illicit connections
- Track flows back to potential dischargers and conduct aboveground inspections. This can
be done through visual inspection of up gradient manholes or alternate techniques
including zinc chloride smoke testing, fluorometric dye testing, physical inspection
testing, or television camera inspection.
- Once the origin of flow is established, require illicit discharger to eliminate the discharge.
Stencil storm drains, where applicable, to prevent illegal disposal of pollutants. Storm drain
inlets should have messages such as “Dump No Waste Drains to Stream” stenciled next to
them to warn against ignorant or intentional dumping of pollutants into the storm drainage
system.
Refer to fact sheet SC-10 Non-Stormwater Discharges.
Illegal Dumping
Regularly inspect and clean up hot spots and other storm drainage areas where illegal
dumping and disposal occurs.
Establish a system for tracking incidents. The system should be designed to identify the
following:
- Illegal dumping hot spots
- Types and quantities (in some cases) of wastes
- Patterns in time of occurrence (time of day/night, month, or year)
- Mode of dumping (abandoned containers, “midnight dumping” from moving vehicles,
direct dumping of materials, accidents/spills)
- Responsible parties
Post “No Dumping” signs in problem areas with a phone number for reporting dumping and
disposal. Signs should also indicate fines and penalties for illegal dumping.
Refer to fact sheet SC-10 Non-Stormwater Discharges.
SC-74 Drainage System Maintenance

www.cabmphandbooks.com
The State Department of Fish and Game has a hotline for reporting violations called Cal TIP
(1-800-952-5400). The phone number may be used to report any violation of a Fish and
Game code (illegal dumping, poaching, etc.).
The California Department of Toxic Substances Control’s Waste Alert Hotline, 1-800-
69TOXIC, can be used to report hazardous waste violations.
Training
Train crews in proper maintenance activities, including record keeping and disposal.
Only properly trained individuals are allowed to handle hazardous materials/wastes.
Train municipal employees from all departments (public works, utilities, street cleaning,
parks and recreation, industrial waste inspection, hazardous waste inspection, sewer
maintenance) to recognize and report illegal dumping.
Train municipal employees and educate businesses, contractors, and the general public in
proper and consistent methods for disposal.
Train municipal staff regarding non-stormwater discharges (See SC-10 Non-Stormwater
Discharges).
Spill Response and Prevention
Refer to SC-11, Prevention, Control & Cleanup
Have spill cleanup materials readily available and in a known location.
Cleanup spills immediately and use dry methods if possible.
Properly dispose of spill cleanup material.
Other Considerations
Cleanup activities may create a slight disturbance for local aquatic species. Access to items
and material on private property may be limited. Trade-offs may exist between channel
hydraulics and water quality/riparian habitat. If storm channels or basins are recognized as
wetlands, many activities, including maintenance, may be subject to regulation and
permitting.
Storm drain flushing is most effective in small diameter pipes (36-inch diameter pipe or less,
depending on water supply and sediment collection capacity). Other considerations
associated with storm drain flushing may include the availability of a water source, finding a
downstream area to collect sediments, liquid/sediment disposal, and disposal of flushed
effluent to sanitary sewer may be prohibited in some areas.
Regulations may include adoption of substantial penalties for illegal dumping and disposal.
Municipal codes should include sections prohibiting the discharge of soil, debris, refuse,
hazardous wastes, and other pollutants into the storm drain system.
Private property access rights may be needed to track illegal discharges up gradient.

Requirements
Costs
An aggressive catch basin cleaning program could require a significant capital and O&M
budget. A careful study of cleaning effectiveness should be undertaken before increased
cleaning is implemented. Catch basin cleaning costs are less expensive if vacuum street
sweepers are available; cleaning catch basins manually can cost approximately twice as
much as cleaning the basins with a vacuum attached to a sweeper.
Methods used for illicit connection detection (smoke testing, dye testing, visual inspection,
and flow monitoring) can be costly and time-consuming. Site-specific factors, such as the
level of impervious area, the density and ages of buildings, and type of land use will
determine the level of investigation necessary. Encouraging reporting of illicit discharges by
employees can offset costs by saving expense on inspectors and directing resources more
efficiently. Some programs have used funds available from “environmental fees” or special
assessment districts to fund their illicit connection elimination programs.
Maintenance
Two-person teams may be required to clean catch basins with vactor trucks.
Identifying illicit discharges requires teams of at least two people (volunteers can be used),
plus administrative personnel, depending on the complexity of the storm sewer system.
Arrangements must be made for proper disposal of collected wastes.
Requires technical staff to detect and investigate illegal dumping violations, and to
coordinate public education.
Supplemental Information
Further Detail of the BMP
Storm Drain flushing
Sanitary sewer flushing is a common maintenance activity used to improve pipe hydraulics and
to remove pollutants in sanitary sewer systems. The same principles that make sanitary sewer
flushing effective can be used to flush storm drains. Flushing may be designed to hydraulically
convey accumulated material to strategic locations, such as to an open channel, to another point
where flushing will be initiated, or over to the sanitary sewer and on to the treatment facilities,
thus preventing re-suspension and overflow of a portion of the solids during storm events.
Flushing prevents “plug flow” discharges of concentrated pollutant loadings and sediments. The
deposits can hinder the designed conveyance capacity of the storm drain system and potentially
cause backwater conditions in severe cases of clogging.
Storm drain flushing usually takes place along segments of pipe with grades that are too flat to
maintain adequate velocity to keep particles in suspension. An upstream manhole is selected to
place an inflatable device that temporarily plugs the pipe. Further upstream, water is pumped
into the line to create a flushing wave. When the upstream reach of pipe is sufficiently full to
SC-74 Drainage System Maintenance
6 of 9 California Stormwater BMP Handbook January 2003
Municipal
www.cabmphandbooks.com
cause a flushing wave, the inflated device is rapidly deflated with the assistance of a vacuum
pump, releasing the backed up water and resulting in the cleaning of the storm drain segment.
To further reduce the impacts of stormwater pollution, a second inflatable device, placed well
downstream, may be used to re-collect the water after the force of the flushing wave has
dissipated. A pump may then be used to transfer the water and accumulated material to the
sanitary sewer for treatment. In some cases, an interceptor structure may be more practical or
required to re-collect the flushed waters.
It has been found that cleansing efficiency of periodic flush waves is dependent upon flush
volume, flush discharge rate, sewer slope, sewer length, sewer flow rate, sewer diameter, and
population density. As a rule of thumb, the length of line to be flushed should not exceed 700
feet. At this maximum recommended length, the percent removal efficiency ranges between 65-
75 percent for organics and 55-65 percent for dry weather grit/inorganic material. The percent
removal efficiency drops rapidly beyond that. Water is commonly supplied by a water truck, but
fire hydrants can also supply water. To make the best use of water, it is recommended that
reclaimed water be used or that fire hydrant line flushing coincide with storm drain flushing.
Flow Management
Flow management has been one of the principal motivations for designing urban stream
corridors in the past. Such needs may or may not be compatible with the stormwater quality
goals in the stream corridor.
Downstream flood peaks can be suppressed by reducing through flow velocity. This can be
accomplished by reducing gradient with grade control structures or increasing roughness with
boulders, dense vegetation, or complex banks forms. Reducing velocity correspondingly
increases flood height, so all such measures have a natural association with floodplain open
space. Flood elevations laterally adjacent to the stream can be lowered by increasing through
flow velocity.
However, increasing velocity increases flooding downstream and inherently conflicts with
channel stability and human safety. Where topography permits, another way to lower flood
elevation is to lower the level of the floodway with drop structures into a large but subtly
excavated bowl where flood flows we allowed to spread out.
Stream Corridor Planning
Urban streams receive and convey stormwater flows from developed or developing watersheds.
Planning of stream corridors thus interacts with urban stormwater management programs. If
local programs are intended to control or protect downstream environments by managing flows
delivered to the channels, then it is logical that such programs should be supplemented by
management of the materials, forms, and uses of the downstream riparian corridor. Any
proposal for steam alteration or management should be investigated for its potential flow and
stability effects on upstream, downstream, and laterally adjacent areas. The timing and rate of
flow from various tributaries can combine in complex ways to alter flood hazards. Each section
of channel is unique, influenced by its own distribution of roughness elements, management
activities, and stream responses.
Drainage System Maintenance SC-74
January 2003 California Stormwater BMP Handbook 7 of 9

Flexibility to adapt to stream features and behaviors as they evolve must be included in stream
reclamation planning. The amenity and ecology of streams may be enhanced through the
landscape design options of 1) corridor reservation, 2) bank treatment, 3) geomorphic
restoration, and 4) grade control.
Corridor reservation - Reserving stream corridors and valleys to accommodate natural stream
meandering, aggradation, degradation, and over bank flows allows streams to find their own
form and generate less ongoing erosion. In California, open stream corridors in recent urban
developments have produced recreational open space, irrigation of streamside plantings, and
the aesthetic amenity of flowing water.
Bank treatment - The use of armoring, vegetative cover, and flow deflection may be used to
influence a channel’s form, stability, and biotic habitat. To prevent bank erosion, armoring can
be done with rigid construction materials, such as concrete, masonry, wood planks and logs,
riprap, and gabions. Concrete linings have been criticized because of their lack of provision of
biotic habitat. In contrast, riprap and gabions make relatively porous and flexible linings.
Boulders, placed in the bed reduce velocity and erosive power.
Riparian vegetation can stabilize the banks of streams that are at or near a condition of
equilibrium. Binding networks of roots increase bank shear strength. During flood flows,
resilient vegetation is forced into erosion-inhibiting mats. The roughness of vegetation leads to
lower velocity, further reducing erosive effects. Structural flow deflection can protect banks
from erosion or alter fish habitat. By concentrating flow, a deflector causes a pool to be scoured
in the bed.
Geomorphic restoration – Restoration refers to alteration of disturbed streams so their form
and behavior emulate those of undisturbed streams. Natural meanders are retained, with
grading to gentle slopes on the inside of curves to allow point bars and riffle-pool sequences to
develop. Trees are retained to provide scenic quality, biotic productivity, and roots for bank
stabilization, supplemented by plantings where necessary.
A restorative approach can be successful where the stream is already approaching equilibrium.
However, if upstream urbanization continues new flow regimes will be generated that could
disrupt the equilibrium of the treated system.
Grade Control - A grade control structure is a level shelf of a permanent material, such as stone,
masonry, or concrete, over which stream water flows. A grade control structure is called a sill,
weir, or drop structure, depending on the relation of its invert elevation to upstream and
downstream channels.
A sill is installed at the preexisting channel bed elevation to prevent upstream migration of nick
points. It establishes a firm base level below which the upstream channel can not erode.
A weir or check dam is installed with invert above the preexisting bed elevation. A weir raises
the local base level of the stream and causes aggradation upstream. The gradient, velocity, and
erosive potential of the stream channel are reduced. A drop structure lowers the downstream
invert below its preexisting elevation, reducing downstream gradient and velocity. Weirs and
drop structure control erosion by dissipating energy and reducing slope velocity.
SC-74 Drainage System Maintenance
8 of 9 California Stormwater BMP Handbook January 2003
Municipal
www.cabmphandbooks.com
When carefully applied, grade control structures can be highly versatile in establishing human
and environmental benefits in stabilized channels. To be successful, application of grade control
structures should be guided by analysis of the stream system both upstream and downstream
from the area to he reclaimed.
Examples
The California Department of Water Resources began the Urban Stream Restoration Program in
1985. The program provides grant funds to municipalities and community groups to implement
stream restoration projects. The projects reduce damages from streambank aid watershed
instability arid floods while restoring streams’ aesthetic, recreational, and fish and wildlife
values.
In Buena Vista Park, upper floodway slopes are gentle and grassed to achieve continuity of
usable park land across the channel of small boulders at the base of the slopes.
The San Diego River is a large, vegetative lined channel, which was planted in a variety of
species to support riparian wildlife while stabilizing the steep banks of the floodway.

adjacent to storm drain inlets. The stencils contain a brief statement that prohibits the dumping
of improper materials into the municipal storm drain system. Graphical icons, either illustrating
anti-dumping symbols or images of receiving water fauna, are effective supplements to the anti-
dumping message. Stencils and signs alert the public to the destination of pollutants discharged
into stormwater. The following requirements should be included in the project design and
shown on the project plans:
TECHNICAL GUIDANCE DOCUMENT
6-5 December 20, 2013
1. Provide stenciling or labeling of all storm drain inlets and catch basins, constructed or
modified, within the project area with prohibitive language (such as: “NO DUMPING-
DRAINS TO OCEAN”) and/or graphical icons to discourage illegal dumping.
2. Post signs and prohibitive language and/or graphical icons, which prohibit illegal
dumping at public access points along channels and creeks within the project area.
3. Maintain legibility of stencils and signs.
See CASQA Stormwater Handbook BMP Fact Sheet SD-13 for additional information.
S2 (SD-34) Design Outdoor Hazardous Material Storage Areas to Reduce
Pollutant Introduction
Improper storage of materials outdoors may increase the potential for toxic compounds, oil and
grease, fuels, solvents, coolants, wastes, heavy metals, nutrients, suspended solids, and other
pollutants to enter the municipal storm drain system. Where the plan of development includes
outdoor areas for storage of hazardous materials that may contribute pollutants to the
municipal storm drain system, or include transfer areas where incidental spills often occur, the
following stormwater BMPs are required:
1. Hazardous materials with the potential to contaminate urban runoff shall either be: (1)
placed in an enclosure such as, but not limited to, a cabinet, shed, or similar structure
that prevents contact with storm water or spillage to the municipal storm drain system;
or (2) protected by secondary containment structures (not double wall containers) such
as berms, dikes, or curbs.
2. The storage area shall be paved and sufficiently impervious to contain leaks and spills.
3. The storage area shall have a roof or awning to minimize direct precipitation and
collection of stormwater within the secondary containment area.
4. Any stormwater retained within the containment structure must not be discharged to
the street or storm drain system.
5. Location(s) of installations of where these preventative measures will be employed must
be included on the map or plans identifying BMPs.
See CASQA Stormwater Handbook Section 3.2.6 and BMP Fact Sheet SD-34 for additional
information.
S3 (SD-32) Design Trash Enclosures to Reduce Pollutant Introduction
Design trash storage areas to reduce pollutant introduction. All trash container areas shall meet
the following requirements (limited exclusion: detached residential homes):
1. Paved with an impervious surface, designed not to allow run-on from adjoining areas,
designed to divert drainage from adjoining roofs and pavements diverted around the
area, screened or walled to prevent off-site transport of trash; and
2. Provide solid roof or awning to prevent direct precipitation.
TECHNICAL GUIDANCE DOCUMENT
6-6 December 20, 2013
Connection of trash area drains to the municipal storm drain system is prohibited.
Potential conflicts with fire code and garbage hauling activities should be considered in
implementing this source control.
See CASQA Stormwater Handbook Section 3.2.9 and BMP Fact Sheet SD-32 for additional
information.
S4 (SD-12) Use Efficient Irrigation Systems and Landscape Design
Projects shall design the timing and application methods of irrigation water to minimize the
runoff of excess irrigation water into the municipal storm drain system. (Limited exclusion:
detached residential homes.) The following methods to reduce excessive irrigation runoff shall
be considered, and incorporated on common areas of development and other areas where
determined applicable and feasible by the Permittee:
1. Employing rain shutoff devices to prevent irrigation after precipitation.
2. Designing irrigation systems to each landscape area’s specific water requirements.
3. Using flow reducers or shutoff valves triggered by a pressure drop to control water loss
in the event of broken sprinkler heads or lines.
4. Implementing landscape plan consistent with County Water Conservation Resolution or
city equivalent, which may include provision of water sensors, programmable irrigation
times (for short cycles), etc.
5. The timing and application methods of irrigation water shall be designed to minimize
the runoff of excess irrigation water into the municipal storm drain system.
6. Employing other comparable, equally effective, methods to reduce irrigation water
runoff.
7. Group plants with similar water requirements in order to reduce excess irrigation runoff
and promote surface filtration. Choose plants with low irrigation requirements (for
example, native or drought tolerant species). Consider other design features, such as:
x Use mulches (such as wood chips or shredded wood products) in planter areas
without ground cover to minimize sediment in runoff.
x Install appropriate plant materials for the location, in accordance with amount of
sunlight and climate, and use native plant material where possible and/or as
recommended by the landscape architect.
x Leave a vegetative barrier along the property boundary and interior
watercourses, to act as a pollutant filter, where appropriate and feasible.
x Choose plants that minimize or eliminate the use of fertilizer or pesticides to
sustain growth.
Irrigation practices shall comply with local and statewide ordinances related to irrigation
efficiency.

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

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

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

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.
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!

Clippings, leaves and soil
Fertilizer
Common Pollutants
Automobile
Oil and grease
Radiator fluids and antifreeze
Cleaning chemicals
Brake pad dust
Home Maintenance
Detergents, cleaners and solvents
Oil and latex paint
Swimming pool chemicals
Outdoor trash and litter
The Ocean Begins at Your Front Door
Trash
Place trash and litter that cannot be recycled in
securely covered trash cans
Whenever possible, buy recycled products
Remember: Reduce, Reuse, Recycle
Pet Care
Always pick up after your pet Flush waste down
the toilet or dispose of it in the trash Pet waste,
if left outdoors, can wash into the street, gutter
or storm drain
If possible, bathe your pets indoors If you must
bathe your pet outside, wash it on your lawn or
another absorbent/permeable surface to keep
the washwater from entering the street, gutter or
storm drain
Follow directions for use of pet care products
and dispose of any unused products at a
HHWCC
Pool Maintenance
Pool and spa water must be dechlorinated and free
of excess acid, alkali or color to be allowed in the
street, gutter or storm drain
When it is not raining, drain dechlorinated pool and
spa water directly into the
sanitary sewer
Some cities may have ordinances that do not allow
pool water to be disposed of in the storm drain
Check with your city
Landscape and Gardening
Do not over-water Water your lawn and garden by
hand to control the amount of water you use or set
irrigation systems to reflect seasonal water needs
If water flows off your yard onto your driveway or
sidewalk, your system is over-watering Periodically
inspect and fix leaks and misdirected sprinklers
Do not rake or blow leaves, clippings or pruning
waste into the street, gutter or storm drain Instead,
dispose of waste by composting, hauling it to a
permitted landfill, or as green waste through your
city’s recycling program
Follow directions on pesticides and fertilizer,
(measure, do not estimate amounts) and do not use
if rain is predicted within 48 hours
Take unwanted pesticides to a HHWCC to be
recycled For locations and hours of HHWCC, call
(714) 834-6752 or visit www oclandfills com
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.

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 toThe 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.
RUNOFF, RAINWATER AND REUSE
For information on how to disconnect a downspout or to install and maintain a
rain barrel or rain garden at your home, please see the Los Angeles Rainwater
Harvesting Program, A Homeowner’s “How-To” Guide, November 2009 at
www.larainwaterharvesting.org/
Water runoff from sprinklers left on too long will carry pollutants into our waterways.
Permeable pavement allows water runoff to
infiltrate through the soil and prevents most
pollutants from reaching the storm drain system.
What is Low Impact Development (LID)?
Low Impact Development (LID) is a method of development that seeks to maintain the natural
hydrologic character of an area. LID provides a more sustainable and pollution-preventative
approach to water management.
New water quality regulations require implementation of LID in larger new developments and
encourage implementation of LID and other sustainable practices in existing residential areas.
Implementing modifications to your lawn or garden can reduce pollution in our environment, conserve
water and reduce your water bill.
Where Does Water Runoff Go?
Stormwater, or water from rainfall events, and runoff from outdoor water use such as
sprinklers and hoses flows from homes directly into catch basins and the storm drain
system. After entering the storm drain, the water flows untreated into streams, rivers,
bays and ultimately the Pacific Ocean. Runoff can come from lawns, gardens, driveways,
sidewalks and roofs. As it flows over hard, impervious surfaces, it picks up pollutants.
Some pollutants carried by the water runoff include trash, pet waste, pesticides, fertilizer,
motor oil and more.
Water Conservation
Pollution not only impairs the water quality for habitat and recreation, it can also reduce
the water available for reuse. Runoff allowed to soak into the ground is cleaned as it
percolates through the soil, replenishing depleted groundwater supplies. Groundwater
provides at least 50% of the total water for drinking and other indoor household activities
in north and central Orange County. When land is covered with roads, parking lots,
homes, etc., there is less land to take in the water and more hard surfaces over which
the water can flow.
In Orange County, 60-70% of water used by residents and businesses goes to irrigation
and other outdoor uses. Reusing rainwater to irrigate our lawn not only reduces the impact
of water pollution from runoff, but it also is a great way to conserve our precious water
resources and replenish our groundwater basin.
Permeable pavement allows water runoff to infiltrate through the soil and prevents most pollutants from reaching the storm drain system.
OTHER WATER CONSERVATION AND
POLLUTION PREVENTION TECHNIQUES
Native Vegetation and Maintenance
“California Friendly” plants or native vegetation can significantly
reduce water use. These plants often require far less fertilizers
and pesticides, which are two significant pollutants found in
Orange County waterways. Replacing water “thirsty” plants and
grass types with water efficient natives is a great way to save water
and reduce the need for potentially harmful pesticides and fertilizer.
Please see the California Friendly Garden Guide produced by the
Metropolitan Water District of Southern California and associated
Southern California Water Agencies for a catalog of California
friendly plants and other garden resources at
www.bewaterwise.com/Gardensoft.
Weed Free Yards
Weeds are water thieves.
They often reproduce quickly
and rob your yard of both
water and nutrients. Weed
your yard by hand if possible.
If you use herbicides to
control the weeds, use only
the amount recommended on
the label and never use it if
rain is forecast within the
next 48 hours.
Soil Amendments
Soil amendments such as green waste (e.g. grass clippings,
compost, etc.) can be a significant source of nutrients and can help
keep the soil near the roots of plants moist. However, they can
cause algal booms if they get into our waterways, which reduces
the amount of oxygen in the water and impacts most aquatic
organisms. It is important to apply soil amendments more than 48
hours prior to predicted rainfall.
IRRIGATE EFFICIENTLY
Smart Irrigation Controllers
Smart Irrigation Controllers have internal clocks as well as sensors that will turn off the sprinklers in response to environmental changes. If it is raining, too windy or too cold, the smart irrigation control sprinklers will automatically shut off.
Check with your local water agency for available rebates on irrigation controllers and smart timers.
• Aim your sprinklers at your lawn, not the sidewalk – By simply adjusting the direction of your sprinklers you can save water, prevent water pollution from runoff, keep your lawn healthy and save money.
• Set a timer for your sprinklers – lawns absorb the water they need to stay healthy within a few minutes of turning on the sprinklers. Time your sprinklers; when water begins running off your lawn, you can turn them off. Your timer can be set to water your lawn for this duration every time.
• Water at Sunrise – Watering early in the morning will reduce water loss due to evaporation. Additionally, winds tend to die down in the early morning so the water will get to the lawn as intended.
• Water by hand – Instead of using sprinklers, consider watering your yard by hand. Hand-watering ensures that all plants get the proper amount of water and you will prevent any water runoff, which wastes water and carries pollutants into our waterways.
• Fix leaks - Nationwide, households waste one trillion gallons of water a year to leaks – that is enough water to serve the entire state of Texas for a year. If your garden hose is leaking, replace the nylon or rubber hose washer and ensure a tight connection. Fix broken sprinklers immediately.
Do your part to prevent water
pollution in our creeks, rivers, bays
and ocean.
Clean beaches and healthy creeks, rivers,
bays, and ocean are important to Orange
County.However, many common household
activities can lead to
water pollution if you’re
not careful.
Litter, oil, chemicals and
other substances that
are left on your yard or
driveway can be blown
or washed into storm
drains that flow to the
ocean. Over-watering
your lawn and washing
your car can also flush
materials into the storm
drains. Unlike water in sanitary sewers
(from sinks and toilets), water in storm
drains is not treated.
You would never pour soap, fertilizers or oil
into the ocean, so don’t let them enter
streets, gutters or storm drains. Follow the
easy tips in this brochure to help prevent
water pollution.GENUINERECYCLEDPAPER

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

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

The tips contained in this brochure provide useful
information to help prevent water pollution while
performing home improvement projects. 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 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.
Printed on Recycled Paper
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 1-877-897-7455 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
Household Hazardous Waste
Collection Center to be recycled.

Printed on Recycled Paper
Never let any pet care products or
washwater run off your yard and into
the street, gutter or storm drain.
Washing Your Pets
Even biodegradable soaps and
shampoos can be harmful to marine
life and the environment.
If possible, bathe your pets indoors
using less-toxic shampoos or have
your pet professionally groomed.
Follow instructions on the products
and clean up spills.
If you bathe your pet outside, wash it
on your lawn or another absorbent/
permeable surface to keep the
washwater from running into the
street, gutter or storm drain.
Flea Control
Consider using oral or topical flea
control products.
If you use flea control products
such as shampoos, sprays or collars,
make sure to dispose of any unused

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

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

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 1-877-897-7455 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 1-877-897-7455 or visit www.ocwatersheds.com to fill
out an incident reporting form.
