SECTION II PROJECT DESCRIPTION
II.1 PROJECT DESCRIPTION
The proposed Pendry Newport Beach project site encompasses approximately 0.85 acres in the City of
Newport Beach. The project site is bounded by Santa Cruz Drive to the west, Newport Center Drive to
the south, and Center Drive to the north and east. The proposed project will include upgrades to areas
around the Island Hotel at Newport Center Drive and Santa Cruz Drive. Specific improvements include
renovations at the main pool area fronting Newport Center Drive, and an event lawn at Santa Cruz
Drive. A Vicinity Map is included in Section VI.
Under existing conditions, the project site is developed as a pool area and event lawn. Adjacent land
uses include the existing Fashion Island Hotel, parking structures, and public streets (Santa Cruz Drive
and Newport Center Drive).
The table below summarizes the proposed project.
DESCRIPTION OF PROPOSED PROJECT
Development
Category
(Model WQMP,
Table 7.11-2; or
7.11-3):
Category 8: All significant redevelopment projects, where significant
redevelopment is defined as the addition or replacement of 5,000 or more
square feet of impervious surface on an already developed site.
Redevelopment does not include routine maintenance activities that are
conducted to maintain original line and grade, hydraulic capacity, original
purpose of the facility, or emergency redevelopment activity required to protect
public health and safety.

Drainage Patterns/
Connections:
Under existing conditions, the drainage pattern is generally from northeasterly
to southwesterly, and toward the roadways, as discussed in the previous
subsection. There are existing public and private storm drain facilities that
accept the drainage. There are public (city-owned) and private storm drain that
currently accept drainage from the project site. The drainage at the pool area
is collected via on-site area drain systems and conveyed to the city of Newport
Beach storm drain in Newport Center Drive. The drainage in the event lawn
currently drains toward a private catch basin in Santa Cruz Drive, and is
conveyed northerly, via a private system, toward the city’s storm drain system
in San Joaquin Hills Road.
Under proposed conditions, the majority of flows will travel in a southwesterly
direction via area drains to exit on to Newport Center Drive in the pool area.
The event lawn area flow will travel in a northeasterly direction via private catch
basin on Santa Cruz Drive and eventually onto San Joaquin Hills Road. Flows
from both proposed areas will drain to Newport Bay, Upper, Newport Bay,
Lower, and eventually the Pacific Ocean.

II.3 HYDROLOGIC CONDITIONS OF CONCERN
The purpose of this section is to identify any hydrologic conditions of concern (HCOC) with respect to
downstream flooding, erosion potential of natural channels downstream, impacts of increased flows on
natural habitat, etc. As specified in Section 2.3.3 of the 2011 Model WQMP, projects must identify
and mitigate any HCOCs. A HCOC is a combination of upland hydrologic conditions and stream
biological and physical conditions that presents a condition of concern for physical and/or biological
degradation of streams.
In the North Orange County permit area, HCOCs are considered to exist if any streams located
downstream from the project are determined to be potentially susceptible to hydromodification impacts
and either of the following conditions exists:
▪ Post-development runoff volume for the 2-yr, 24-hr storm exceeds the pre-development runoff
volume for the 2-yr, 24-hr storm by more than 5 percent
or
▪ Time of concentration (Tc) of post-development runoff for the 2-yr, 24-hr storm event exceeds
the time of concentration of the pre-development condition for the 2-yr, 24-hr storm event by
more than 5 percent.
If these conditions do not exist or streams are not potentially susceptible to hydromodification impacts,
an HCOC does not exist and hydromodification does not need to be considered further. In the North
Orange County permit area, downstream channels are considered not susceptible to hydromodification,
and therefore do not have the potential for a HCOC, if all downstream conveyance channels that will
receive runoff from the project are engineered, hardened, and regularly maintained to ensure design
flow capacity, and no sensitive habitat areas will be affected.
Is the proposed project potentially susceptible to hydromodification impacts?
☐ Yes ☒ No (show map)
The project site does not fall within the susceptibility to hydromodification impacts.

III.1 PHYSICAL SETTING
Planning Area/
Community Name: The Pendry
Address: 690 Newport Center Drive, Newport Beach CA 92660
Land Use: Commercial
Zoning: North Newport Center
Acreage: 0.85
Predominant Soil Type: Type B according to TGD Figure XVI-2a
III.2 SITE CHARACTERISTICS
Precipitation Zone: 0.70” according to TGD Figure XVI-1
Topography:
The surface topography of the of the site generally slopes away from the
buildings, toward the roadways, with the pool area portion of the site
generally draining toward Newport Center Drive, and the event lawn
area draining toward Santa Cruz Drive.
Drainage Patterns/
Connections:
See Section II.1 and Section II.4 for a complete description of existing
and proposed drainage patterns and connections.
Soil Type, Geology, and
Infiltration Properties:
A geotechnical study was performed for the site in December 2013 by
NMG Geotechnical, Inc. The excavations resulted from the
demolition operations should be cleared of loose materials to establish
a firm subgrade prior to backfilling operations. Backfill materials may
consist of onsite soils that are free of organics and/or deleterious
materials. The hydrologic soil group is B according to the custom soil
resource report from the NRCS included in the Hydrology report. Due
to high bedrock, several nearby subterranean structures that cannot be
undermined, and the project site located on an archeological site,
infiltration is infeasible.
Hydrogeologic
(Groundwater)
Conditions:
The project site is not in a potential landslide area, not in an area of
shallow (less than 10’) groundwater, not in a potential area of erosion,
habitat and physical structure susceptibility, and not in an area of a
groundwater plume.
Final Water Quality Management Plan (WQMP)
Pendry Newport Beach
690 Hotel, LLC, c/o Eagle Four Partners 8 Best Management Practices
Geotechnical Conditions
(relevant to infiltration):
The project site has high bedrock, several nearby subterranean
structures that cannot be undermined, and the project site is on an
archeological site. Therefore, direct or concentrated infiltration of runoff
is not considered feasible for the project. See also Appendices A and F

IV.1 PROJECT PERFORMANCE CRITERIA
Is there an approved WIHMP or equivalent for the project area that includes more stringent LID feasibility
criteria or if there are opportunities identified for implementing LID on regional or sub-regional basis?
☐ Yes ☒ No
PROJECT PERFORMANCE CRITERIA
Hydromodification
Control Performance
Criteria:
(Model WQMP Section
7.II-2.4.2.2)
If a hydrologic condition of concern (HCOC) exists, priority projects shall
implement onsite or regional hydromodification controls such that:
▪ Post-development runoff volume for the two-year frequency storm
does not exceed that of the predevelopment condition by more than
five percent, and
▪ Time of concentration of post-development runoff for the two-year
storm event is not less than that for the predevelopment condition by
more than five percent.
Where the Project WQMP documents that excess runoff volume from the
two-year runoff event cannot feasibly be retained and where in-stream
controls cannot be used to otherwise mitigate HCOCs, the project shall
implement on-site or regional hydromodification controls to:
▪ Retain the excess volume from the two-year runoff event to the MEP,
and
▪ Implement on-site or regional hydromodification controls such that
the post-development runoff two-year peak flow rate is no greater
than 110 percent of the predevelopment runoff two-year peak flow
rate.
LID Performance
Criteria:
(Model WQMP Section
7.II-2.4.3)
Infiltrate, harvest and use, evapotranspire, or biotreat/biofilter, the 85th
percentile, 24-hour storm event (Design Capture Volume).
LID BMPs must be designed to retain, on-site, (infiltrate, harvest and use,
or evapotranspire) storm water runoff up to 80 percent average annual
capture efficiency.
Treatment Control
BMP Performance
Criteria:
(Model WQMP Section
7.II-3.2.2)
If it is not feasible to meet LID performance criteria through retention
and/or biotreatment provided on-site or at a sub-regional/regional scale,
then treatment control BMPs shall be provided on-site or offsite prior to

IV.2 SITE DESIGN AND DRAINAGE PLAN
The following section describes the site design BMPs used in this project and the methods used to
incorporate them. Careful consideration of site design is a critical first step in storm water pollution
prevention from new developments and redevelopments.
IV.2.1 Site Design BMPs
Minimize Impervious Area
The project will increase impervious surfaces as compared to existing conditions. However, landscaping
will be provided throughout the site within the common areas as well as around the perimeter of the
site.
Maximize Natural Infiltration Capacity
Infiltration is not recommended for the project site due to high bedrock, several nearby subterranean
structures that cannot be undermined, and the project site is on an archeological site.
Preserve Existing Drainage Patterns and Time of Concentration
Runoff from the site will continue to flow similar to existing conditions. Flows will be routed to a Modular
Wetland System for water quality treatment via biotreatment.
Disconnect Impervious Areas
Landscaping will be provided adjacent to sidewalks and between the existing hotel buildings.
Protect Existing Vegetation and Sensitive Areas, and Revegetate Disturbed Areas
There are no existing vegetated or sensitive areas to preserve on the project site. All disturbed areas
will either be paved or landscaped.
Xeriscape Landscaping
Xeriscape landscaping is not proposed for the project. Native and/or tolerant landscaping will be
incorporated into the site design consistent with City guidelines.

IV.2.2 Drainage Management Areas
In accordance with the MS4 permit and the 2011 Model WQMP, the project site has been divided into
Drainage Management Areas (DMAs) to be utilized for defining drainage areas and sizing LID and other
treatment control BMPs. DMAs have been delineated based on the proposed site grading patterns,
drainage patterns, storm drain and catch basin locations.
The design capture volumes (DCV) and treatment flow rates (QDesign) for each DMA are summarized in
the table below. These have been derived utilizing the “Simple Method” in accordance with the TGD
Section III.1.1. Additional calculations and TGD Worksheets are provided in Appendix A.

IV.3 LID BMP SELECTION AND PROJECT CONFORMANCE ANALYSIS
Low Impact Development (LID) BMPs are required in addition to site design measures and source
controls to reduce pollutants in storm water discharges. LID BMPs are engineered facilities that are
designed to retain or biotreat runoff on the project site. The 4th Term MS4 Storm Water Permit (Order
R8-2009-0030) requires the evaluation and use of LID features using the following hierarchy of
treatment: infiltration, evapotranspiration, harvest/reuse, and biotreatment. The following sections
summarize the LID BMPs proposed for the project in accordance with the permit hierarchy and
performance criteria outlined in Section IV.1.
IV.3.1 Hydrologic Source Controls (HSCs)
Hydrologic source controls (HSCs) can be considered to be a hybrid between site design practices and
LID BMPs. HSCs are distinguished from site design BMPs in that they do not reduce the tributary area
or reduce the imperviousness of a drainage area; rather they reduce the runoff volume that would result
from a drainage area with a given imperviousness compared to what would result if HSCs were not
used.

Due to the high amounts of pervious area within DMA A, impervious area dispersion is proposed. This
was confirmed with the City (phone call 7-20-2022). The pervious area achieves the minimum
dispersion requirement and 80% capture efficiency is met. See table below for a summary of the
calculations as well as Appendix A.

IV.3.2 Infiltration BMPs
Infiltration BMPs are LID BMPs that capture, store and infiltrate storm water runoff. These BMPs are
engineered to store a specified volume of water and have no design surface discharge (underdrain or
outlet structure) until this volume is exceeded. Examples of infiltration BMPs include infiltration trenches,
bioretention without underdrains, drywells, permeable pavement, and underground infiltration galleries.

No infiltration BMPs are proposed within the redevelopment project. As discussed in Section III.2, the
project site has high bedrock, several nearby subterranean structures that cannot be undermined, and
the project site is on an archeological site. Therefore, direct or concentrated infiltration of runoff is not
considered feasible for the project. See also Appendices A and F for further details.
IV.3.3 Rainwater Harvesting BMPs
Harvest and use (aka. Rainwater Harvesting) BMPs are LID BMPs that capture and store storm water
runoff for later use. These BMPs are engineered to store a specified volume of water and have no design
surface discharge until this volume is exceeded. Harvest and use BMPs include both above-ground and
below-ground cisterns. Examples of uses for harvested water include irrigation, toilet and urinal flushing,
vehicle washing, evaporative cooling, industrial processes and other non-potable uses.
HARVEST & REUSE / RAINWATER HARVESTING
ID Name Included?
HU-1 Above-ground cisterns and basins ☐
HU-2 Underground detention ☐
-- Other: ☐
For a system to be considered “feasible”, the system must be designed with a storage volume equal to
the DCV from the tributary area and achieve more than 40% capture. The system must also be able to
drawdown in 30 days to meet the 40% capture value. This is determined by calculating the Estimated
Applied Water Use (EAWU) equation from Appendix X of the TGD. The EAWU can then be divided by
Final Water Quality Management Plan (WQMP)
Pendry Newport Beach
690 Hotel, LLC, c/o Eagle Four Partners 14 BMP Inspection & Maintenance
the water quality volume for the project site or DMA to determine drawdown time. If the drawdown time
is less than 30 days, harvest and reuse is considered partially feasible and the Effective Irrigated Area
to Tributary Area (EIATA) ratio may be utilized to determine the capture efficiency of the system. If
drawdown is greater than 30 days, harvest and reuse may be concluded to be infeasible.
As shown by Worksheet J included in Appendix A, harvest and reuse is considered partially feasibility.
However, due to space constraints from the pool and utilities within DMA B, and a slope within DMA A,
a harvest and reuse storage system is considered infeasible from a technical standpoint. Harvest and
reuse would also require a separate irrigation system would which increase the scope of redevelopment
of this project. Harvest and reuse is considered infeasible for both DMAs.
IV.3.4 Biotreatment BMPs
Biotreatment BMPs are a broad class of LID BMPs that reduce storm water volume to the maximum
extent practicable, treat storm water using a suite of treatment mechanisms characteristic of biologically
active systems, and discharge water to the downstream storm drain system or directly to receiving waters.
BIOTREATMENT

BIO-2 Vegetated swales ☐
BIO-3 Vegetated filter strips ☐
BIO-7 Proprietary vegetated biotreatment systems ☒
BIO-4 Wet extended detention basin ☐
BIO-6 Dry extended detention basins ☐
-- Other: ☐
Since both infiltration and harvest and reuse are considered infeasible, biotreatment BMPs will be utilized
for water quality treatment of DMA B.
There are several advantages of the Modular Wetland System over traditional bioretention planters
including the following reasons:
▪ Modular Wetlands are the only proprietary biotreatment device approved through the
Washington State University TAPE (Technology Assessment Protocol – Ecology) program for
basic storm water treatment and enhanced treatment including sediment, nutrients and heavy
Final Water Quality Management Plan (WQMP)
Pendry Newport Beach
690 Hotel, LLC, c/o Eagle Four Partners 15 BMP Inspection & Maintenance
metals (all proposed pollutants of concern for the Upper Newport Bay). TAPE approval is
based on a series of independent field studies using strict sampling criteria to validate
vendor’s claims. TAPE approval is considered one of the most stringent and most reliable in
the country.
▪ Modular Wetlands have a pre-treatment chamber that is specifically designed to capture fine
sediments and particulates through a series of BioMediaGREEN sponges which prohibit the
fines and particulates from entering the bioretention chamber and accelerating potential
clogging of the bioretention soil.
▪ Modular Wetland Systems are specifically designed for higher flow through treatment rates
which reduce the potential for nutrient and copper leaching under more stagnant conditions
(a common occurrence with planters that are left unmaintained).
Modular Wetlands by Modular Wetlands Systems, Inc. are proprietary biotreatment systems that utilize
multi-stage treatment processes including screening media filtration, settling, and biofiltration. The pre-
treatment chamber contains the first three stages of treatment and includes a catch basin inlet filter to
capture trash, debris, gross solids and sediments, a settling chamber for separating out larger solids,
and a media filter cartridge for capturing fine TSS, metals, nutrients, and bacteria. Runoff then flows
through the wetland chamber where treatment is achieved through a variety of physical, chemical, and
biological processes. As storm water passes down through the planting soil, pollutants are filtered,
adsorbed, biodegraded and sequestered by the soil and plants, functioning similar to bioretention
systems. The discharge chamber at the end of the unit collects treated flows and discharges back into
the storm drain system.
This system was selected based on its ability to treat the project’s pollutants of concerns to a medium or
high effectiveness, in accordance with the Model WQMP and TGD requirements. The table below
summarizes the overall treatment effectiveness for Modular Wetlands, derived from Table 4.2 of the
Technical Guidance Document and testing data provided by the manufacturer. Additional details for
the Modular Wetland System are included in Section VI of this WQMP.

IV.4 ALTERNATIVE COMPLIANCE PLAN
IV.4.1 Water Quality Credits
Final Water Quality Management Plan (WQMP)
Pendry Newport Beach
690 Hotel, LLC, c/o Eagle Four Partners 20 BMP Inspection & Maintenance
Local jurisdictions may develop a water quality credit program that applies to certain types of
development projects after they first evaluate the feasibility of meeting LID requirements on-site. If it is
not feasible to meet the requirements for on-site LID, project proponents for specific project types can
apply credits that would reduce project obligations for selecting and sizing other treatment BMPs or
participating in other alternative programs.
WATER QUALITY CREDITS
Credit Applicable?
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 water quality 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. ☐
Not applicable. Water quality credits will not be applied for the project. LID BMPs will be utilized for
water quality treatment on-site in accordance with the MS4 Permit hierarchy identified at the beginning

BIO-7: Proprietary Biotreatment
Proprietary biotreatment devices are devices that are
manufactured to mimic natural systems such as bioretention
areas by incorporating plants, soil, and microbes engineered
to provide treatment at higher flow rates or volumes and
with smaller footprints than their natural counterparts.
Incoming flows are typically filtered through a planting
media (mulch, compost, soil, plants, microbes, etc.) and
either infiltrated or collected by an underdrain and delivered
to the storm water conveyance system. Tree box filters are an
increasingly common type of proprietary biotreatment device
that are installed at curb level and filled with a bioretention
type soil. For low to moderate flows they operate similarly to
bioretention systems and are bypassed during high flows.
Tree box filters are highly adaptable solutions that can be
used in all types of development and in all types of soils but
are especially applicable to dense urban parking lots, street,
and roadways.
Feasibility Screening Considerations
x Proprietary biotreatment devices that are unlined may cause incidental infiltration. Therefore, an
evaluation of site conditions should be conducted to evaluate whether the BMP should include an
impermeable liner to avoid infiltration into the subsurface.
Opportunity Criteria
x Drainage areas of 0.25 to 1.0 acres.
x Land use may include commercial, residential, mixed use, institutional, and subdivisions.
Proprietary biotreatment facilities may also be applied in parking lot islands, traffic circles, road
shoulders, and road medians.
x Must not adversely affect the level of flood protection provided by the drainage system.
OC-Specific Design Criteria and Considerations
□ Frequent maintenance and the use of screens and grates to keep trash out may decrease the
likelihood of clogging and prevent obstruction and bypass of incoming flows.
□ Consult proprietors for specific criteria concerning the design and performance.
□ Proprietary biotreatment may include specific media to address pollutants of concern. However,
for proprietary device to be considered a biotreatment device the media must be capable of
supporting rigorous growth of vegetation.
□
Proprietary systems must be acceptable to the reviewing agency. Reviewing agencies shall
have the discretion to request performance information. Reviewing agencies shall have the
discretion to deny the use of a proprietary BMP on the grounds of performance, maintenance
considerations, or other relevant factors.

□ In right of way areas, plant selection should not impair traffic lines of site. Local jurisdictions
may also limit plant selection in keeping with landscaping themes.
Computing Sizing Criteria for Proprietary Biotreatment Device
x Proprietary biotreatment devices can be volume based or flow-based BMPs.
x Volume-based proprietary devices should be sized using the Simple Design Capture Volume
Sizing Method described in Appendix III.3.1 or the Capture Efficiency Method for Volume-Based,
Constant Drawdown BMPs described in Appendix III.3.2.
x The required design flowrate for flow-based proprietary devices should be computed using the
Capture Efficiency Method for Flow-based BMPs described in Appendix III.3.3).

HSC-2: IMPERVIOUS AREA DISPERSION
Impervious area dispersion refers to the practice of routing
runoff from impervious areas, such as rooftops, walkways,
and patios onto the surface of adjacent pervious areas via
sheet flow. Runoff is dispersed uniformly via splash block or
dispersion trench 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 localized on-lot storage (See MISC-2 if localized
ponding is intended).
In contrast to HSC-1, this practice can be used where
infiltration is either fully feasible or partially feasible.
Recommended Selection and Siting Criteria
•Impervious area dispersion can be used in DMAs
categorized as feasible for full infiltration or partial
infiltration. It should be avoided if any level of infiltration
would pose hazards.
•This HSC requires that there are significant pervious areas present in drainage area with shallow
slopes that can receive runoff from adjacent impervious areas.
•The site plan should allow for verflow from pervious area to be appropriately managed.
Recommended Design Criteria and Considerations
□ Soils should be preserved from their natural condition or restored via soil amendments to
meet minimum criteria described in MISC-2.
□Lawn or landscaping should be well established
□ A minimum of 1 part pervious area capable of receiving flow should be provided for every 2 parts
of impervious area disconnected.
□ The pervious area receiving flow should have a slope ≤ 2 percent and path lengths of ≥ 20 feet
per 1000 sf of impervious area.
□ For areas with sparse vegetation (e.g.. xeriscaped areas), appropriate contouring should be used
to slow water, avoid preferential scour pathways and associated soil or mulch loss.
□ Dispersion areas should be maintained to remove trash and debris, loose vegetation, and protect
any areas of bare soil from erosion.
□Velocity of dispersed flow should not be greater than 0.5 ft per second to avoid scour.

TECHNICAL GUIDANCE DOCUMENT APPENDICES
South Orange County Version G-7 September 28, 2017
Calculating HSC Retention Volume
• The retention volume provided by
downspout dispersion is a function of the
ratio of impervious to pervious area and
the condition of soils in the pervious area.
• Determine flow patterns in pervious area
and estimate footprint of pervious area
receiving dispersed flow. Calculate the
ratio of pervious to impervious area.
• Look up the storm retention depth, dHSC
from the chart below.
• The max dHSC is equal to the design
capture storm depth for the project site.
1 Pervious area used in calculation should
only include the pervious area receiving
flow, not pervious area receiving only direct
rainfall or upslope pervious drainage.
Chart extends to 0.25, but designs should
not go below a minimum value of 0.5 (2
parts impervious to 1 part pervious).

Table 2.7: Infiltration BMP Feasibility Worksheet
Infeasibility Criteria Yes No
1
Would Infiltration BMPs pose significant risk for
groundwater related concerns? Refer to Appendix VII
(Worksheet I) for guidance on groundwater-related
infiltration feasibility criteria.
X
Provide basis:
No infiltration BMPs are proposed within the redevelopment project. The project site has high
bedrock, several nearby subterranean structures that cannot be undermined, and the project
site is on an archeological site. Therefore, direct or concentrated infiltration of runoff is not
considered feasible for the project.
Summarize findings of studies provide reference to studies, calculations, maps, data sources,
etc. Provide narrative discussion of study/data source applicability.
2
Would Infiltration BMPs pose significant risk of
increasing risk of geotechnical hazards that cannot
be mitigated to an acceptable level? (Yes if the
answer to any of the following questions is yes, as
established by a geotechnical expert):
The BMP can only be located less than 50 feet away
from slopes steeper than 15 percent
The BMP can only be located less than eight feet from
building foundations or an alternative setback.
A study prepared by a geotechnical professional or an
available watershed study substantiates that stormwater
infiltration would potentially result in significantly
increased risks of geotechnical hazards that cannot be
mitigated to an acceptable level.
X
Provide basis:
Summarize findings of studies provide reference to studies, calculations, maps, data sources,
etc. Provide narrative discussion of study/data source applicability.
3 Would infiltration of the DCV from drainage area violate
downstream water rights? X
Worksheets from Orange County Technical Guidance Document (5-19-2011)
See TGD for instructions and/or examples related to these worksheets
www.ocwatersheds.com/WQMP.aspx
Provide basis:
Summarize findings of studies provide reference to studies, calculations, maps, data sources,
etc. Provide narrative discussion of study/data source applicability.
Table 2.7: Infiltration BMP Feasibility Worksheet (continued)
Partial Infeasibility Criteria Yes No
4
Is proposed infiltration facility located on HSG D soils or
the site geotechnical investigation identifies presence of soil
characteristics which support categorization as D soils?
X
Provide basis:
Summarize findings of studies provide reference to studies, calculations, maps, data sources,
etc. Provide narrative discussion of study/data source applicability.
5
Is measured infiltration rate below proposed facility
less than 0.3 inches per hour? This calculation shall be
based on the methods described in Appendix VII.
X
Provide basis:
Infiltration testing has not been done at this time.
Summarize findings of studies provide reference to studies, calculations, maps, data sources,
etc. Provide narrative discussion of study/data source applicability.
6
Would reduction of over predeveloped conditions cause
impairments to downstream beneficial uses, such as
change of seasonality of ephemeral washes or
increased discharge of contaminated groundwater to
surface waters?
X
Provide citation to applicable study and summarize findings relative to the amount of infiltration
that is permissible:
Summarize findings of studies provide reference to studies, calculations, maps, data sources,
etc. Provide narrative discussion of study/data source applicability.

Table 2.7: Infiltration BMP Feasibility Worksheet (continued)
7
Would an increase in infiltration over predeveloped
conditions cause impairments to downstream
beneficial uses, such as change of seasonality of
ephemeral washes or increased discharge of
contaminated groundwater to surface waters?
X
Provide citation to applicable study and summarize findings relative to the amount of infiltration
that is permissible:
Summarize findings of studies provide reference to studies, calculations, maps, data sources,
etc. Provide narrative discussion of study/data source applicability.
Infiltration Screening Results (check box corresponding to result):
8
Is there substantial evidence that infiltration from the project
would result in a significant increase in I&I to the sanitary
sewer that cannot be sufficiently mitigated? (See Appendix
XVII)
Provide narrative discussion and supporting evidence:
Summarize findings of studies provide reference to studies,
calculations, maps, data sources, etc. Provide narrative
discussion of study/data source applicability.
9
If any answer from row 1-3 is yes: infiltration of any volume
is not feasible within the DMA or equivalent.
Provide basis:
No infiltration BMPs are proposed within the redevelopment
project. The project site has high bedrock, several nearby
subterranean structures that cannot be undermined, and the
project site is on an archeological site. Therefore, direct or
concentrated infiltration of runoff is not considered feasible
for the project.

10
If any answer from row 4-7 is yes, infiltration is permissible
but is not presumed to be feasible for the entire DCV.
Criteria for designing biotreatment BMPs to achieve the
maximum feasible infiltration and ET shall apply.
Provide basis:
Summarize findings of infeasibility screening
11
If all answers to rows 1 through 11 are no, infiltration of the
full DCV is potentially feasible, BMPs must be designed to

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 (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.
Tips for Home Improvement Projects
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.
Pollution Prevention
Household Activities
�Do not rinse spills with water!Sweep
outdoor spills and dispose of in the trash.
For wet spills like oil, apply cat litter or
another absorbent material, then sweep
and bring to a household hazardous waste
collection center (HHWCC).
�Securely cover trash cans.
�Take household hazardous waste to a house-
hold hazardous waste collection center.
�Store household hazardous waste in closed,
labeled containers inside or under a cover.
�Do not hose down your driveway, sidewalk or
patio. Sweep up debris and dispose of in trash.
�Always pick up after your pet. Flush waste
down the toilet or dispose of in the trash.
�Bathe pets indoors or have them
professionally groomed.
Household Hazardous Wastes include:
�Batteries
�Paint thinners, paint strippers and removers
�Adhesives
�Drain openers
�Oven cleaners
�Wood and metal cleaners and polishes
�Herbicides and pesticides
�Fungicides/wood preservatives

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.

C lean beaches
and healthy
creeks, rivers, bays
and ocean are important to
Orange County. However,
many common activities
can lead to water pollution
if you’re not careful. Pet
waste and pet care products
can be washed into the
storm drains that flow to
the ocean. Unlike water in
sanitary sewers (from sinks
and toilets), water in storm
drains is not treated before
entering our waterways.
You would never put pet
waste or pet care products
into the ocean, so don’t let
them enter the storm drains.
Follow these easy tips to help
prevent water pollution.

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
products at
a Household
Hazardous
Waste
Collection
Center. For
location
information,
call (714) 834-6752.
Why You Should Pick Up After
Your Pet
It’s the law!
Every city has
an ordinance
requiring you
to pick up
after your pet.
Besides being
a nuisance, pet
waste can lead to water pollution, even
if you live inland. During rainfall, pet
waste left outdoors can wash into storm
drains. This waste flows directly into our
waterways and the ocean where it can
harm human health, marine life and
the environment.
As it decomposes, pet waste demands
a high level of oxygen from water.
This decomposition can contribute to
killing marine
life by reducing
the amount of
dissolved oxygen
available to
them.
Have fun with
your pets, but
please be a
responsible pet
owner by taking
care of them and the environment.
Take a bag with you on walks to pick
up after your pet.
Dispose of the waste in the trash or in
a toilet.

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

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!

This information was provided by the County of Orange Integrated Waste Management Department and the California Integrated Waste Management Board (CIWMB).
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 at least 50% of the total water for drinking and other indoor household activities in
north and central Orange County. When land is covered with roads, parking lots, homes,
etc., there is less land to take in the water and more hard surfaces over which the water
can flow.
In Orange County, 60-70% of water used by residents and businesses goes to irrigation
and other outdoor uses. Reusing rainwater to irrigate our lawn not only reduces the impact
of water pollution from runoff, but it also is a great way to conserve our precious water
resources and replenish our groundwater basin.
Permeable pavement allows water runoff to infiltrate through the soil and prevents most pollutants from reaching the storm drain system.
OTHER WATER CONSERvATION AND POLLUTION PREvENTION TECHNIqUES
Native Vegetation and Maintenance
“California Friendly” plants or native vegetation can significantly
reduce water use. These plants often require far less fertilizers
and pesticides, which are two significant pollutants found in
Orange County waterways. Replacing water “thirsty” plants and
grass types with water efficient natives is a great way to save water
and reduce the need for potentially harmful pesticides and fertilizer.
Please see the California Friendly Garden Guide produced by the
Metropolitan Water District of Southern California and associated
Southern California Water Agencies for a catalog of California
friendly plants and other garden resources at
www.bewaterwise.com/Gardensoft.
Weed Free Yards
Weeds are water thieves.
They often reproduce quickly
and rob your yard of both
water and nutrients. Weed
your yard by hand if possible.
If you use herbicides to
control the weeds, use only
the amount recommended on
the label and never use it if
rain is forecast within the next
48 hours.
Soil Amendments
Soil amendments such as green waste (e.g. grass clippings,
compost, etc.) can be a significant source of nutrients and can help
keep the soil near the roots of plants moist. However, they can
cause algal booms if they get into our waterways, which reduces
the amount of oxygen in the water and impacts most aquatic
organisms. It is important to apply soil amendments more than 48
hours prior to predicted rainfall.
IRRIgATE EFFICIENTLY
Smart Irrigation
Controllers
Smart Irrigation Controllers have internal clocks as well as sensors that will turn off the sprinklers in response to environmental changes. If it is raining, too windy or too cold, the smart irrigation control sprinklers will automatically shut off.
Check with your local water agency for available re-bates on irrigation controllers and smart timers.
• Aim your sprinklers at your lawn, not the sidewalk – By simply adjusting the direction of your sprinklers you can save water, prevent water pollution from runoff, keep your lawn healthy and save money.
• Set a timer for your sprinklers – lawns absorb the water they need to stay healthy within a few minutes of turning on the sprinklers. Time your sprinklers; when water begins running off your lawn, you can turn them off. Your timer can be set to water your lawn for this duration every time.
• Water at Sunrise – Watering early in the morning will reduce water loss due to evaporation. Additionally, winds tend to die down in the early morning so the water will get to the lawn as intended.
• Water by hand – Instead of using sprinklers, consider watering your yard by hand. Hand-watering ensures that all plants get the proper amount of water and you will prevent any water runoff, which wastes water and carries pollutants into our waterways.
• Fix leaks - Nationwide, households waste one trillion gallons of water a year to leaks – that is enough water to serve the entire state of Texas for a year. If your garden hose is leaking, replace the nylon or rubber hose washer and ensure a tight connection. Fix broken sprinklers immediately.

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

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.
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!

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

Dispersion
Impervious area dispersion refers to the practice of routing
runoff from impervious areas, such as rooftops, walkways,
and patios onto the surface of adjacent pervious areas via
sheet flow. Runoff is dispersed uniformly via splash block or
dispersion trench 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 localized on-lot storage.

Biotreatment BMP # 1: Modular Wetland System (MWS)
Modular Wetlands by Modular Wetlands Systems, Inc. are
proprietary biotreatment systems that utilize multi-stage
treatment processes. The pre-treatment chamber contains the
first three stages of treatment, and includes a catch basin inlet
filter to capture trash, debris, gross solids and sediments, a
settling chamber for separating out larger solids, and a media
filter cartridge for capturing fine TSS, metals, nutrients, and
bacteria. Runoff then flows through the wetland chamber
where treatment is achieved through a variety of physical,
chemical, and biological processes. As storm water passes
down through the planting soil, pollutants are filtered,
adsorbed, biodegraded and sequestered by the soil and
plants, functioning similar to bioretention systems. The
discharge chamber at the end of the unit collects treated flows
and discharges back into the storm drain system.
Inspect system at a minimum of once every six
months, prior to the start of the rainy season
(October 1), and after major storm events.
Typical maintenance includes removing trash &
debris from the catch basin screening filter (by
hand), removal of sediment and solids in the
settlement chamber (vacuum truck), replacement
of the BioMediaGREENTM filter cartridge, and
replacement of the BioMediaGREENTM drain
down filter (if equipped). In addition, plants
within the wetland chamber will require trimming
in conjunction with landscape maintenance
activities. See attached manufacturer’s
specifications for additional requirements.

Newport Beach, California 92660
Attention: Mr. Kory Kramer
Subject: Geotechnical Opinion Regarding Storm Water Infiltration at Pendry Hotel, Fashion Island, City of Newport Beach, California
Per the request of the project civil engineer, Fuscoe Engineering, we have prepared this report in
order to provide our geotechnical opinion regarding the potential infiltration of storm water into the
underlying soils at the Pendry Hotel site (Formerly Island Hotel) for purposes of the Water Quality Management Plan (WQMP). We have reviewed the available geotechnical data related to the site and have extensive experience with the geology of Fashion Island area in Newport Beach,
California. We have prepared this report based on our knowledge of the potential geotechnical
issues related to the potential infiltration of surface waters at the site.
The existing geologic conditions at the subject site consist of compacted fill locally overlying marine terrace deposits and bedrock of the Monterey Formation. The terrace deposits are uplifted ancient beach sands that were laid down on a wave cut bench made of bedrock. The site has two
terrace levels and a complex geologic structure. The terrace materials generally have a high
permeability; however, the bedrock has relatively low fracture permeability in the upper weathered
bedrock. Throughout the Newport Beach coastal area where water infiltrates through the terrace
sands, it often becomes perched on the wave cut bench and in the weathered bedrock, then travels laterally down-gradient along the bench and seeps out of the ground surface where the terrace/bedrock contact is exposed at grade.
Following completion of the proposed grading at the site, there will be compacted fill at the surface
that will have generally low permeability. Below the fill, the thickness of the marine terrace
deposits will vary between 0 and 20 feet thick (thickest at the southwest portion of the site). The marine terrace deposits are anticipated to have moderate permeability, but if additional surface water is introduced into these deposits it will likely increase the nuisance seepage issues in the
down-gradient areas, especially in basements or subterranean levels in some of the retail buildings
and parking structures in Fashion Island.

220628 NMG
As a result of the above, NMG does not recommend utilization of infiltration BMPs at the subject
site for purposes of the WQMP.
If you have any questions regarding this report, please contact our office. We appreciate the
opportunity to provide our services.
