I. Project Description
1.1 Project Description and Vicinity Map
WESTIN LOT 9
SWMP -January 2015
The proposed development is located in the City of Carlsbad County of San Diego, CA. The majority of
the project is located at the south eastern corner of the intersection of Cannon Road and Grand
Pacific Drive, while a small portion of the project is located South West of the aforementioned
intersection. The site is currently a graded pad with an existing paved access road. Some portion of
graded area is currently being used for agriculture. The grading of the proposed site was completed
during phase I of the project. A portion of the proposed project was developed during phase II of the
project. The site is approximately 21.160 acres, with 13.337 acres of disturbed area.
The proposed development will contain a combination of parking lots/areas, swimming pools,
landscaping and dwelling or building areas. Infrastructure will include new storm drain and inlets as
well as water and sewer main extensions and new dry utilities runs/extensions to service the lot.
During Phase II of the project a portion of the proposed project was permitted (villas 60-64). This
project proposes to slightly change the position of villas 60-64 as well as change the size of these
buildings. As will be discussed later in this report the impermeable area in the location of these villas
will be increased compared to the previously permitted condition. As such, this study address the
required treatment needed for the runoff for this additional area along with the portions of the
project that have not been previously permitted. The proposed site plan also includes Villa 67,
however the building footprint for this building has not changed since it was originally proposed
under drawing number 428-9G. The Bio-swale at the south west boundary was designed to treat the
runoff for this building. The sizing of this bioswale was not included in this report.

1.3 Proposed Land use and anticipated activities that would affect Stormwater
Proposed Land use is Multi-apartment building (time share) and recreation facility.
The first flush of storm water will be treated by TCBMP submerged flow through planters and the
100 year-storm event will be over flowing to the catch basins/ grated inlets or flow through planter
emergency outlet/weir. Flow through planters are designed to treat storm water pollution and also
to detain 10% of 2 to 10 year storm event volume to attenuate the post-development's peak flow to
the pre-development's peak flow rate to mimic the existing condition, and attenuate for continuous
storm events per HMP requirements. All run-offs will be directed to landscape and/or bio-retention
areas before they are released to the public storm drain.
1.4 Nearby waterbodies and Impaired waterbodies
This project is located in the Carlsbad Hydrologic Unit (904.00), The southernmost outfall discharges
to the Encinas Hydrologic Watershed (904.40). Receiving water downstream is Canyon De Las
Encinas and eventually to Pacific Ocean. The Northern most outfall discharges to The Aqua Hedionda
Lagoon watershed (904.30). The Carlsbad Hydrologic Unit is approximately 210 square miles in area
extending from the headwaters above Lake Wohlford in the east to Pacific Ocean in the west and
from Vista and Oceanside in the north to Solana Beach, Escondido, and the community of Rancho
Santa Fe to the south.
The proposed project is designed so that it will not significantly alter the drainage pattern on the site.
The surface water runoff discharge will not divert from existing conditions. This project will not
present any potential threat to erosion or water quality deterioration.
II. Applicable Stormwater Standards
2.1. Stormwater Standard Questionnaires (SWSQ)
To address post-development pollutants that may be generated from development projects and
meet the City of Carlsbad requirements a Stormwater Standard Questioners is completed. Please
refer to Attachment A for this completed form.

2.2. Lawful Prior Compliance
The Water Quality or Stormwater Management and Maintenance for this portion of the site was
covered in the original entitled CEQA Master SWMP document for the entire Carlsbad Ranch,
Planning Area No.5 Site. The referenced CEQA Master SWMP document was dated from July 2004.
Consequently, the water quality measures that were outlined in the overall CEQA Master SWMP
were constructed under the Phase I portion of the site (Per DWG.NO. 428-9A dated 9-27-2005, and
outlined in the SWMP for Phase I, dated May 2005). A number of these measures fall within the
footprint of the proposed Phase II portion of the site and were designed to treat some portion of this
area. These include: Perimeter Bio-swales, ultimate downstream storm drain outfall pipes as well as
off-site detention ponds constructed per adjacent projects (located at Palomar Airport Road). Mass
grading for the Phase II area was also performed per permitted plans (DWG. No. 428-9A) and SWMP
11-5.
These were all completed in compliance with the original Master CEQA SWMP for the site. This
proposed project provides treatment control such as bioretentions to treat potential pollutants, and
to control peak runoff and durations.
This SWMP for Phase III is an addendum to that previously referenced master plan in order to comply
with the current LID requirements per the <;ity susMp. Depending on whether the project is defined
as being under "lawful prior compliance" per the new BMP Design Manual effective December 2015,
the storm water treatment and hydro modification design may change at final construction design.
2.3 Hydromodification
This project is subject to the current Hydromodification Management Plan requirements. A
downstream channel assessment has not been completed for this project and therefore the low flow
threshold utilized for the system analysis is 10% of 2-year storm event (0.lQ2). This will be used as
the low flow threshold to meet peak flow frequency and flow duration controls. The high flow
threshold is 10% of the 10-year storm event.
The Hydromodification and Water Quality calculations were performed utilizing continuous
simulation analysis to size the storm water treatment and control facilities. Storm Water
Management Model (SWMM) version 5.0 distributed by USEPA is the basis of all calcuiations within
this report. SWMM generates peak flow recurrence frequencies and flow duration series statistics
based on an assigned rain gauge for pre-development, unmitigated post-development flows and
post-development mitigated flows to determine compliance with the State Water Resources Control
Board Order 2009-0009-DWQ and the County wide Model Standard Urban Stormwater Management
Plan (SUSMP) and Hydromodification Management Plan (HMP) requirements. The HMP is included in
attachment C of this report.

3.2 Identify Pollutants associated with type of Land use
Distance to Project
0.75 miles
0.75 miles
As discussed on section 1.2 regarding proposed land use and anticipated activities that would affect
Stormwater have the potential to contribute the following pollutants:
Trash and Debris -Trash (such as paper, plastic, polystyrene packing foam, and aluminum materials)
and biodegradable organic matter (such as leaves, grass cuttings, and food waste) are general waste
products on the landscape. The presence of trash and debris may have a significant impact on the
recreational value of a water body and aquatic habitat. Excess organic matter can crate a high
biochemical oxygen demand in stream and thereby lower its water quality. In addition, in areas
where stagnant water exists, the presence of excess organic matter can promote septic conditions
resulting in the growth of undesirable organisms and the release of odorous and hazardous
compounds such as hydrogen sulfide.
Oxygen-Demanding Substances -This category includes biodegradable organic material as well as
chemicals that react with dissolved oxygen in water to form other compounds. Proteins,

carbohydrates, and Fats are examples of biodegradable organic compounds. Compounds such as
Ammonia and Hydrogen sulfide are examples of oxygen-demanding compounds. The oxygen
demand of a substance can lead to depletion of dissolved oxygen in a water body and possibly the
development of septic conditions.
Oil and Grease -Oil and grease are characterized as high-molecular weight organic compounds.
Primary sources of oil and grease are petroleum hydrocarbon products, motor products from leaking
vehicles, esters, oils, fats, waxes, and high molecular-weight fatty acids. Introduction of these
pollutants to the water bodies are very possible due to the wide use and applications of some of
these products in municipal, residential, commercial, industrial, and construction areas. Elevated oil
and grease content can decrease the aesthetic value of the water body, as well as the water quality.
Pathogens -Pathogens (bacteria and viruses) are ubiquitous microorganisms that thrive under
certain environmental conditions. Their proliferation is typically caused by the transport of animal or
human fecal wastes from the watershed. Water, containing excessive bacteria and viruses can alter
the aquatic habitat and create a harmful environment for humans and aquatic life. Also, the
decomposition of excess organic wastes causes increased growth of undesirable organisms in the
water.
Pesticides -Pesticides (including herbicides) are chemical compound commonly used to control
nuisance growth or prevalence of organisms. Excessive or improper application of a pesticide may
result in runoff containing toxic levels of its active ingredient.
Nutrients -Nutrients are in organic substances, such as nitrogen and phosphorus. They commonly
exist in the form of mineral salts that are either dissolved or suspended in water. Primary' sources or
nutrients in urban runoff are fertilizers and eroded soils. Excessive discharge of nutrients to water
bodies and streams can cause excessive aquatic algae and plant growth. Such excessive production,
referred to as Cultural Eutrophication, may lead to excessive decay of organic matter in the water
body, loss of oxygen in the water, release of toxins in sediment, and the eventual death of aquatic
organisms.
Metals -the primary source of metal pollution in urban runoff is typically commercially available
metals and metal products. Metals of concern include Cadmium, Chromium, Copper, Lead, mercury,
and zinc. Lead and chromium have been used as corrosion inhibitors in primer coatings and cooling
tower systems. Metals are also raw material components in non-metal products such as fuels,
adhesives, paints, and other coatings. At low concentrations naturally occurring in soil, metals may
not be toxic. However, at higher concentrations, certain metals can be toxic to aquatic life. Humans
can be impacted from contaminated groundwater resources, and bioaccumulation of metals in fish
and shellfish. Environmental concerns, regarding the potential for release of metals to the
environment, have already led to restricted metal usage in certain applications.
Sediments -Sediments are soils or other surficial materials eroded and then transported or
deposited by the action of wind, water, ice or gravity. Sediments can increase turbidity, clog fish gills,
reduce spawning habitat, lower young aquatic organisms survival rates, smoother bottom dwelling
organisms, and suppress aquatic vegetation growth.

3.4 Summary of primary pollutants of concern
This major part of the project is located in the Carlsbad Hydrologic Unit (904.00), Encin~s Hydrologic
watershed (904.40). Receiving water downstream is Canyon De Las Encinas Creek (904.40) and
eventually to Pacific Ocean.
The impaired water-bodies is NOT listed in 303(d) 2010 lists.
Therefore, the primary pollutants of concern for the project are unknown. The secondary pollutants
are sediments, Nutrients, Oxygen Demanding substances, heavy metal, trash, debris, oil and grease
and pesticides.
IV. Source Control Measures
4.1 Description of site activities and potential sources of pollutants
Source control BMPs are structured around the concept of lIactivities" as experience has shown that with few
exceptions one or more of these activities will satisfactorily describe all commercial facilities.
Storm Drain Signage
Storm drain inlets and access points to natural drainage courses will be marked to discourage illegal
dumping, with markings indicating the receiving water by name. Specifically:
1. All storm drain inlets and catch basins within the project area will have a tile or signage placed
with prohibited language (such as: 'NO DUMPING -DRAINS TO PACIFIC OCEAN SHORElINE")
2. Signs and prohibited language and lor graphical icons, which prohibit illegal dumping, must be
posted at public access points along channels and creeks within the project area.
3. Legibility of tiles and signs must be maintained and tiles must be placed flush with the top of
concrete to reduce tripping by pedestrians.
Trash and debris from general site hotel/villa use and other sources will be prevented. Prevention is
chiefly from the fact that guests or concerned individuals when properly informed of the consequences of
irresponsible disposal of thrash and debris will eventually affect our water bodies. Brochures provided by
the developer/owner for the renters or tenants as a form of educating all concerned will provide an extra
plus to this BMP.
Street Sweeping
Street sweeping scheduled at appropriate intervals (we recommend a minimum of bi-weekly interval [this
is based on economy and approximate accumulation of dirt and sediments], however it is per the
discretion of management to schedule this activity for the well ness and ambiance of the hotel/villa) can
reduce pollutants that have built up over time and become deposited from vehicles, plants and other
vegetations along sidewalks and islands. It is recommended that this BMP be implemented expeditiously
or upon completion of paving construction of all internal driveways and parking lots.
The following will be minimized:
1. Trash and debris from general site hotel/villa use, and from drivers & pedestrians
2. Sediments and soils contaminated with oils and similar products associated with automobiles.
12
Landscaping
WESTIN LOT 9
SWMP -January 2015
Landscaping of the slopes and other parts of the site will be incorporated into the plans. To expeditiously
achieve plant establishment to reduce erosion, landscaping will consist of both native and non-native
plants. The irrigation system will be closely monitored to reduce over irrigation and thus protect the
manufactured slopes from being destabilized due to over watering and over saturation of the soil.
Maintenance of vegetated or landscaped areas (street sidewalks, street landscaped islands or slopes) and
other planted areas should be the responsibility of the owner or corporation handling the property. This
owner will develop a schedule and funding scheme when the project is turned over by the
contractor/developer to them.

5.1. Description of site activities and potential sources of pollutants
To minimize Stormwater-related impacts, the following design principles are applied to the layout of the site:
• Detain and retain runoff throughout the site
This project implements bio-retention basins w/impervious liner with underdrain pipes connected to
an existing riser. Bio-retention basins can convey high flows while percolating and treating lower
flows.
An LID facility must be selected to treat the project pollutants of concern identified in Table 2 "Project
Pollutants of Concern". A treatment control facility with high or medium pollutant removal efficiency for the
project's most significant pollutant of concern shall be selected. Bioretention facilities provide a high removal
efficiency for course sediment, trash and pollutants that associate with fine particles and a medium removal
efficiency for pollutants that dissolve following treatment, per table 2-2 and 2-3 of the city SUSMP and Table 6
below.

This project is designed to have buildings and circulation to minimize the amount of roofs and paving.
Use of Pervious Surfaces and drain impervious area to Engineered Bio-retention
Turf associated with landscape is widely used where possible in this project. All impervious areas will drain to
one of seven Bio-retention facilities. Bio-retention areas are used as a storm water retaining and treatment
facility, and is used to convey 100 year, 6 hour storm flows coming from the site. They bio-retention basins for
the project are proposed to be lined with impervious liners. The will contain 4" underdrain pipes with stand
pipes with top of grates higher than the bio-swale finish grade. This under drain pipe and the stand pipe
configuration will reduce the water level on the bio-swale faster during a large storm events. A detail showing
the basic layout of the proposed bio basins is provided below.

Drainage Management Areas (DMAs)
The entire project area is divided into individual Drainage Management Areas (DMAs). This delineation was
done by following grade breaks and roof ridge lines. There ;:Ire 2 outfalls in the post-development condition:
Outfall-A, at the south end of the project -For the post-developed condition runoff will be treated by various
bio-retention basins and then will be routed through the existing bio-swale at the South Western portion of
the project. The bio-swale (IMP 6) is only sized to treat the existing impermeable surfaces previously installed
on the project. Runoff will be routed to the swale for flow mitigation purposes only. Once the flow leaves the
swale it will be conveyed to meet the eXisting public storm drain at the southernmost portion of the project.
Outfall-B, to the North East of the Project -Discharge from the site will be diverted into one oftwo bio-
retention basins labelled as IMP 1 and IMP 4. After the runoff is treated by the ponds itwill be conveyed
directly into the public storm drain in Cannon Rd.
Integrated Management Practice (IMP)
All run-offs from impervious surface will be treated by a Integrated Management Practice (IMP) facilities. The
routing into each bio-retention pond can be found on the BMP site plan exhibit attached to this report and is
discussed in the previous section on this report.

INTRODUCTION
This report provides Hydromodification and Water Quality design based on LID (Low Impact Development)
principles for the proposed Sheraton Hotel and Timeshare Resort Phase III -Carlsbad Ranch, Planning Area 5,
Carlsbad, California. This project is located at Cannon Road and Grand Pacific Drive. The site is currently a
graded pad with an existing paved access road. Some portion of graded area is currently being used for
agriculture. The grading of the proposed site was completed during phase I, Drawing #428-9A, of the project.
During Phase II, Drawing #428-9G, of the project villas 60-64 were permitted. This project proposes to slightly
change the position of villas 60-64 as well as change the size of these buildings. Therefore this analysis
includes these areas.
The developed project is comprised of several tributary areas directed to several bio-retention ponds with two
points of compliance (OUTFALL A and OUTFALL B). This system detains storm water in the basin surface and
also in the underdrain reservoir. Bio-retention filters storm water through plant roots and a biologically active
soil mix, and then releases it into the existing storm drain system which currently collects the sites storm
flows. The resulting mitigated outflows are shown to be equal to or less than all continuously simulated
storms based on the historical data collected from the Oceanside rain gage. The HMP analysis was performed
to include all areas that drain to the existing bio-swale located at the South West of the project. This bio-swale
was installed in phase 2 of the project. This portion of the project was completed prior to the requirement to
perform HMP analysis for the drainage of the site, as a result the bio-swale was designed only to limit the
runoff for the 100 year storm to less than the pre-existing condition. For the current phase of the project
runoff for Outfall A will be routed through this same bio-swale (labelled in this report as Bio-Swale 6) after it
has been routed to several different bio-retention ponds around the project to meet hydromod requirements.
The Hydromodification and Water Quality calculations were performed utilizing continuous simulation
analysis to size the storm water treatment and control facilities. Storm Water Management Model (SWMM)
version 5.0 distributed by USEPA is the basis of all calculations within this report. SWMM generates peak flow
recurrence frequencies and flow duration series statistics based on an assigned rain gauge for pre-
development, unmitigated post-development flows and post-development mitigated flows to determine
compliance with the State Water Resources Control Board Order 2009-0009-DWQ and the County wide Model
Standard Urban Stormwater Management Plan (SUSMP) and Hydromodification Management Plan (HMP)
requirements.
Low Flow Threshold
A downstream channel assessment has not been completed for this project and therefore the low flow
threshold utilized for the system analysis is 10% of 2-year storm event (0.lQ2). This will be used as the low
flow threshold to meet peak flow frequency and flow duration controls.
Soil characteristics
Based on Natural Resources Conservation Service Soil Survey Map this project is categorized as soil type B
loamy coarse sand. The USDA NRCS soil texture classification was used to determine the average soil capillary
suction, saturated hydraulic conductivity rate and the soil initial moisture deficit. The full printout from the
USDA NRCS soils report is attached to this report.

SECTION I. MODEL SETUP
Pre-development Model Setup
The SWMM model for this projects pre-development site is analyzed using historical rain gauge data. The
Oceanside gauge was utilized for this project. That data provides continuous precipitation input to a sub-
catchment with its outfall based on the contributing basins imperviousness.
The imperviousness parameter in SWMM is the amount of effective or directly connected impervious area.
The effective impervious area is the impervious area that drains directly to the Stormwater conveyance
system. The pre-development condition is partially developed from phase 2 of the existing project. The
Post-Development Model Setup
Figure 3a and 3b illustrate each contributing basin discharging its overland flow directly into the bio-retention
system. Each bio-retention layer section has a similar configuration as seen as inthe detail drawing below.
There is no actual elevation entered in the program. The bottom elevation of the bio-retention surface storage
is assumed at 0 ft.

SECTION II. SYSTEM REPRESENTATION
SWMM is a distributed model, which means that a study area can be subdivided into any number of
irregular sub-catchments to best capture the effect that spatial variability in topography, drainage
pathways, land cover, and soil characteristics have on runoff generation. For modeling of
Hydromodification calculations, there are four main system representations: Rain gage, Sub-catchment
(contributing basin or LID area), Nodes and Links.

Fig. 4 -Time series rain data, which corresponds to runoff estimates for each of the 508,080 time steps (each
date and hour) of the 58-year simulation period. (Inches/hour vs. elapsed time)
Rain Gauge
The properties of a rain gauge describe the source and format of the precipitation data that are applied
to the study area. In this project, the rainfall data consist of a long-term rainfall record stored in a user"
defined Time Series labeled as "Oceanside" rain gauge station. The Oceanside rain station was chosen
due to its data quality and its location to the project site.
The rain gauge supplies precipitation data for one or more sub-catchment areas in a study region taken
from the Project Clean Water website (www.projectcleanwater.org).This data file contains rainfall
intensity, hourly-recorded time interval, and the dates of recorded precipitation each hour. The
Oceanside rain data has approximately 58 years of hourly precipitation data from 8/28/1951 to
5/23/2008 and generates 58 years of hourly runoff estimates, which corresponds to runoff estimates for
each of the 508,080 time steps (each date and hour) of the 58 year simulation period. See figure 1 for
hourly precipitation intensity graph for 58 years in inches.
Sub-catchment (contributing basin or LID area)
A basin is modeled using a sub-catchment object, which contains some of the following proPerties:
9
Rain Gauge
The rate of stormwater runoff and volume depends directly on the precipitation magnitude and its
spatial and temporal distribution over the catchment. Each sub-catchment in SWMM is linked to a rain
gauge object that describes the format and source of the rainfall input for the sub-catchment.
Area
This area is bounded by the sub-catchment boundary. Its value is determined directly from maps or field
surveys of the site or by using SWMM's Auto-length tool when the sub-catchment is drawn to scale on
SWMM's study area map. This Project is divided into several sub-catchments based on its outfall.
Width
Width can be defined as the sub-catch me nt's area divided by the length of the longest overland flow
path that water can travel. When there are several such paths, one would use an average of their
lengths to compute a width. If overland flow is visualized as running down -slope off an idealized,
rectangular catchment, then the width of the sub-catchment is the physical width of overland flow.
In natural areas, true overland flow can only occur for distances of about 500 feet before it begins to
consolidate into a small stream flow. In post-development, the true overland flow can be very short
before it is collected into open channels. A maximum overland flow of 500 ft is appropriate for a non-
urban catchment, while the typical overland flow length is appropriate for non-urban catchments; the
typical overland flow length is the length from the back of a representative lot to the center of the street
for urban catchments. If the overland flow length varies greatly within a sub-catchment, then an area-
weighted average should be used.

Slope
This is the slope of the land surface over which runoff flows and is the same for both the pervious and
impervious surfaces. It is the slope of what one considers being the overland flow path or its area-
weighted average if there are several paths in the sub-catchment.
Imperviousness
This is the percentage of sub-catchment area covered by impervious surfaces such as sidewalks and
roadways or whatever surfaces that rainfall cannot infiltrate. The sub catchment contains mix surface
types such as roofs, AC pavement, pervious pavers and/or landscape.
Roughness Coefficient
The roughness coefficient reflects the amount of resistance that overland flow encounters as it runs off
of the sub-catchment surface.
Infiltration Model
The pre-development condition is primarily empty land with moderate vegetation cover. In the model,
Loam was used for the post-development condition and the pre-development condition. Infiltration of
rainfall from the pervious area of a sub-catchment into the unsaturated upper soil zone can be
described using three different infiltration models: Horton, Green-Ampt, and Curve Number. There is no
general agreement on which method of these three is the best.
The Green-Ampt method was chosen to calculate the infiltration of the pervious areas based on the
availability of data for this project. It is invoked when editing the infiltration property of a sub-
catchment.

LID controls
Utilizing LID controls within a SWMM project is a two-step process that:
Creates a set of scale-independent LID controls that can be deployed throughout the study area,
Assign any desired mix and sizing of these controls to designated sub-catchments.
The LID control type that was selected was a bio-retention cell that contains vegetation grown in an
engineered soil mixture placed above a gravel drainage bed. Bio-retention provides storage,
infiltration (depending on the soil type) and evaporation of both direct rainfall and runoff captured
from surrounding areas. For this project, we allowed infiltration to the existing/filled soil at rate of
2.22 in./hr according to the percolation testing performed onsite. This test is attached to this report.

SECTION IV. BIO-RETENTION AS LID CONTROL
LID controls are represented by a combination of vertical layers whose properties are defined on a per-
unit-area basis. This allows an LID of the same design but differing coverage area to easily be placed
within different sub-catchments of a study area. During a simulation, SWMM performs a moisture
balance that keeps track of how much water moves between and is stored within each LID layer. If the
bio-retention basin is full and water is leaving the upper weir, the flow is divided in two flows: the lower
flow discharging from the bottom orifice directly draining to the point of compliance and the upper flow
is routed at the top of the bio-retention basin and after routing, discharged to the point of compliance.
In this project, we used 100% of the area of this specific sub-catchment for bio-retention.
In SWMM a divider was used to model this condition. All sub-catchments in one tributary area were
directed to a Flow Divider. A Flow Divider is a drainage system node that diverts inflow to a specific
conduit in a prescribed manner such as a cutoff type. A Flow Divider with a cutoff type diverts all inflow
above a defined cutoff value, in this case we used an orifice equation: Discharge= q = CA[2g(h-Hd)]o.s.
A detention basin sub routine was added at the top of the bio-retention where a weir is added for
control purposes, and the storage curve is also provided, see the next section "Modeling bio-retention
surface ponding in SWMM 5.0".
1. Surface
Storage Depth
When confining walls or berms are present, this is the maximum depth to which water can pond above
the surface of the unit before overflow occurs (in inches). In this SWMM model, surface storage depth
was not modeled inside the LID editor but was modeled in the storage.
Vegetation Volume Fraction
It is the fraction of the volume within the storage depth that is filled with vegetation. This is the volume
occupied by stems and leaves, not their surface area coverage. Normally this volume can be ignored, but
may be as high as 0.1 to 0.2 for very dense vegetative growth. Based on our visual observation in the
field, the average type of vegetation for this site is a low-density vegetation type. Therefore, we used 0.1
for the vegetation volume fraction assuming type of vegetation used is a low-density type.
Surface Roughness
Manning's n value for overland flow over a vegetative surface. We used n=0.025 -0.040 for bio-retention
vegetative cover.
Surface Slope
Slope of porous pavement surface or vegetative swale (percent). We use 0.5 percent for bio-retention.

2. Soil
Thickness
The thickness of the soil layer (inches). We used a typical value for a bio-retention, which is 18" for the
ponds.
Porosity
The volume of pore space relative to total volume of soil (as a fraction). We designed it with a soil mix
porosity of 0.40 maximum for a good percolation rate (Countywide Model SUSMP Table Bl-Soil
Porosity Appendix A: Assumed Water Movement Hydraulics for Modeling BMPs).
Field Capacity
Volume of pore water relative to total volume after the soil has been allowed to drain fully (as a
fraction). We used 0.105 for this soil. Below this level, vertical drainage of water through the soil layer
does not occur. (See Table 1-Soil Infiltration Parameter).
Wilting Point
Volume of pore water relative to total volume for a well-dried soil where only bound water remains (as
a fraction). The moisture content of the soil cannot fall below this limit.
We assumed the minimum moisture content within this bio-retention soil is 0.047.
Conductivity
Hydraulic conductivity for the fully saturated soil is 5 inches/hour. This is a design minimum value for
percolation rate.
Conductivity Slope
Slope of the curve of log (conductivity) versus soil moisture content (dimensionless). Typical values
. range from 5 for sands to 15 for silty clay. We designed this soil to have a very good percolation rate
therefore the conductivity slope is 7 (pro-rated value taken from scale 5 for sand and 15 for Silty-clay
over 11 types of soil texture classification)
Suction Head
The average value of soil capillary suction along the wetting front (inches). This is the same parameter as
used in the Green-Ampt infiltration model. Table 1 was utilized to determine the capillary of the soil mix
top layer of a bio-retention system. Loamy Sand was considered for approximately 10% clay content and
sedimentation collected during a rain event, therefore the suction head will be 2.41 inches. This is an
assumption of a suction head for the soil mix after several years of bio-retention life span.

------------------------------------------------------------------------------------------------,
3. Storage Layer
The Storage Layer page of the LID Control Editor describes the properties of the crushed stone or gravel
layer used in bio-retention cells as a bottom storage/drainage layer. The following data fields are
displayed:
Height
this is the thickness of a gravel layer (inches). Crushed stone and gravel layers are varies please refer to
Table 3 on the next page.
Void Ratio
The volume of void space relative to the volume of solids in the layer. Typical values range from 0.5 to
0.75 for gravel beds. Note that porosity = void ratio / (1 + void ratio). We designed this void ratio to have
a value of 0.65.
Conductivity
The rate at which water infiltrates into the native soil below the layer (in inches/hour). This would
typically be the Saturated Hydraulic Conductivity of the surrounding sub-catchment if Green-Ampt
infiltration is used. Since impervious liner is applied for this project, we assumed no infiltration rate to
the native soil.
Clogging Factor
Total volume of treated runoff it takes to completely clog the bottom of the layer divided by the void
volume of the layer. For south east bio-retention, a value of 0 was used to ignore clogging since the
system does NOT consider infiltration to the native soils. Clogging progressively reduces the Infiltration
Rate in direct proportion to the cumulative volume of runoff treated and may only be of concern for
infiltration trenches with permeable bottoms and no under drains. We assumed zero for the clogging
factor since the infiltration rate is not considered.
4. Underdrain Layer
LID storage layers can contain an optional underdrain system that collects stored water from the bottom
of the layer and conveys it to a conventional storm drain. The Underdrain page of the LID Control Editor
describes the properties of this system. It contains the following data entry fields:
Drain Coefficient and Drain Exponent
Coefficient C and exponent n that determines the rate of flow through the underdrain as a function of
height of stored water above the drain height. The following equation is used to compute this flow rate
(per unit area of the LID unit):
q = C(h-Hdr
where q is the outflow (in/hr), h is the height of stored water (inches), and Hd is the drain height. A
typical value for n would be 0.5 (making the drain act like an orifice).
Drain Offset Height
Height of any underdrain piping above the bottom of a storage layer (inches). In this project, this value
was set to 0 as the underdrain piping is at the bottom of the storage layer.

STUDY RESULTS
The above values of SWMM "e" factor, which is directly related to the orifice size, and the Divider flow
rate which is also a function of the underdrain orifice size, are put into the SWMM model. After running
the SWMM input files with the SWMM program and then doing a statistical comparison of the pre and
post development conditions, the results of the statistical analysis show that the project passes
hydromodification requirements using the above orifice sizing and soil layer depths.
V. MODELING BIO-RETENTION SURFACE PONDING
The main elements used to design surface ponding in SWMM are storage units (labeled as IMP _Pond#)
with orifice and weir outlets.
Storage Units
Storage units are drainage system nodes that provide storage volume. Physically they could represent
storage facilities as small as a catch basin or as large as a lake. The volumetric properties of a storage
unit are described by a function or table of surface area versus height. Storage volume is described by a
storage curve, an evaporation factor and a maximum depth of storage.

Outlets
Outlets are flow control devices that are typically used to control outflows from storage units. Outlets
are internally represented in SWMM as a link connecting two nodes. Outlets attached to storage units
are active under all types of flow routing.
A user-defined rating curve determines an outlet's discharge flow as a function of either the freeboard
depth above the outlet's opening or the head difference across it.
19
SECTION V. RUNNING THE SIMULATION
In general, the Run time will depend on the complexity of the watershed being modeled, the routing
method used, and the size of the routing time step used. The larger the time steps, the faster the
simulation, but the less detailed the results.
Model Results
SWMM's Status Report summarizes overall results for the 58-yr simulation. The runoff continuity error is
-3.57 % and the flow routing continuity error is 0.02%. When a run completes successfully, the mass
continuity errors for runoff, flow routing, and pollutant routing will be displayed in the Run Status
window. These errors represent the percent difference between initial storage + total inflow and final
storage + total outflow for the entire drainage system. If they exceed some reasonable level, such as 10
percent, then the validity of the analysis results must be questioned. The most common reasons for an
excessive continuity error are computational time steps that are too long or conduits that are too short.
In addition to the system continuity error, the Status Report produced by a run will list those nodes of
the drainage network that have the largest flow continuity errors. If the error for a node is excessive,
then one should first consider if the node in question is of importance to the purpose of the simulation.
If it is, then further study is warranted to determine how the error might be reduced.
The SWMM program ranks the partial duration series, the exceedance frequency and the return period.
They are computed using the Weibull formula for plotting position. See the flow duration curve and
peak flow frequency on the following pages.
SECTION VI. RESULT ANALYSIS
Development of the Flow Duration Statistics
The flow duration statistics are also developed directly from the SWMM binary output file. It should be
noted right from the start that the "durations" that we are talking about in this section have nothing to
do with the "storm durations" presented in the peak flow statistics section. Other than using the same
sequence of letters for the word, the two concepts have nothing to do with each other and the reader is
cautioned not to confuse the two. The goal of the flow duration statistics is to determine, for the flow
rates that fall within the hydromorphologicaly significant range, the length of time that each of those
flow rates occur. Since the amount of sediment transported by a river or stream is proportional to the
velocity of the water flowing and the length of time that velocity of flow acts on the sediment, knowing
the velocity and length of time for each flow rate is very useful.

Methodology
The methodology for determining the flow duration curves comes from a document developed by the
u.s. Geological Survey (USGS). The first stop on the-journey to find this document was a link to the
USGS water site (http://www.usgs.gov/water/).This link is found in Appendix E (SDHMP Continuous
Simulation Modeling Primer), found in the County Hydromodification Management Plan1• On this web
site a search for "Flow Duration Curves" leads to USGS Publication 1542-A, Flow-duration curves, by
James K. Searcy 1959 (http://pubs.er.usgs.gov/publication/wsp1542A). In this publication the
development of the flow duration curves is discussed in detail.
in Pub 1542-A, beginning on page 7 an example problem is used to illustrate the compilation of data
used to create the flow duration plots. A completed form 9-217-c form shows the monthly tabulation of
flow rates for Bowie Creek near Hattiesburg, Miss. For each flow range the number of readings js
tabulated and then the total number of each flow rate is totaled for the year. It should be noted that
while this example is for a stream with a minimum flow rate of 100cfs, for the purposes of run-off
studies in Southern California the minimum flow rate of zero (0) cfs is the common low flow value. Once
each of the year's data has been compiled the summary numbers from each year are transferred to
form 9-217-d. On this form the total number of each flow rate is again totaled and the percentage of
time exceeded calculated (as will be explained later under the discussion of our calculations). Once the
data has been compiled a graph of Discharge Rate vs. Percent Time Exceeded is developed. As will be
explained in the next section, the use of these curves leads to the amount of time each particular flow
can be expected to occur (based on historical data).
How to Read the Graphs2
Figure 1 shows a flow duration curve for a hypothetical development. The three curves show what
percentage of the time a range of flow rates are exceeded for three different conditions: pre-project,
post-project and post-project with storm water mitigation. Under pre-project conditions the minimum
geomorphically significant flow rate is 0.10cfs (assumed) and as read from the graph, flows would equal
or exceed this value about 0.14% of the time (or about 12 hours per year) (0.0014 x 365days x 24
hOur/day). For post-project conditions, this flow rate would occur more often -about 0.38% of the time
(or about 33 hours per year) (0.0038 x 365days x 24 hour/day). This increase in the duration of the
geomorphically significant flow after development illustrates why duration control is closely linked to

The first step in developing the flow duration curves is to count the number of occurrences of each flow
rate. This is done by first rounding every non-zero flow value to an appropriate number of decimal
places (say two places). This in effect groups each flow into closely related values or "bins" as they are
referred to in publication 9-217d. Then the entire runoff record is queried for each value and the
number of each value counted. The next step is to enter the results ofthe query into a grid patterned
after form 9-217d. The data is entered in ascending order starting with the lowest flow first. The grid is
composed of four columns. They are (from left to right) Discharge Rate, Number of Periods (count),
Total Periods Exceeding (the total number of periods equal to or exceeding this value), and Percent Time
Exceeded. Starting at the top row (row 1), the flow rate (which is often times zero) is entered with the
corresponding number of times that value was found. The next column is the total number of values
greater than or equal to that flow rate. For the first flow rate point, by definition all flow rate values are
greater than or equal to this value, therefore the total number of runoff records of the rainfall record is
entered here. The final column which is the percent of time exceeded is calculated by dividing the total
periods exceeded by the total number of periods in the study. For the first row this number should be
100%
For the next row (row 2), the flow rate, and the flow rate count are entered. The total number of
periods exceeding for row 2 is calculated by subtracting Number of Periods of row 1 from the Total
Periods Exceeding of line 1. This result is entered in the Total Periods Exceeding on row 2. As was the

case for line 1, the final column is calculated by dividing the total periods exceeded by the total n'umber
of periods in the study. For the second row this number should be something less than 100% and
continually decrease as we move down the chart. If all the calculations are correct, then everything
should zero out on the last line of the calculations.
The final step in developing the flow duration curves is to make a plot of the Discharge Rate vs. the
Percent Time Exceeded. For the purposes of this report, the first value corresponding to the zero flow
rate is not plotted allowing the graph to be focused on the actual flow rate values.
The Flow Duration Analysis
The Peak Flow Statistics analysis is composed of the following series of files:
1. The Flow Duration Plot
2. Comparison of the Un-Mitigated Flow Duration Curve to the Pre-Development Curve (Pass/Fail)
3. Comparison of the Mitigated Flow Duration Curve to the Pre-Development Curve (Pass/Fail)
4. The calculations for the Pre-Development flow duration curve development (USGS92).7d)
5. The calculations for the Post-Development flow duration curve development (USGS9217d)
6. The calculations for the Mitigated flow duration curve development (USGS9217d)
The Flow Duration Plot
The Flow Duration Curves Plot is the plotting of all three (pre, un-mitigated and mitigated) sets of
Discharge Rate vs. the Percent Time Exceeded data point pair lists. In addition to these curves
horizontal lines are plotted corresponding to the 010 and OJf (low flow threshold) values. Within the
geomorphically significant range (010 -OJf) one can see a visual representation of the relative positions
of the flow duration curves. The flow duration curves are compared in an East/West (horizontal)
direction to compare post development Discharge Rates to pre-development Discharge Rates. The pre-
development curve is plotted in blue, the unmitigated curve is plotted in red, and the mitigated curve is
plotted in green. As long as the post development curve lies to the left ofthe pre-development'curve
(mostly3), the project meets the peak flow hydromodification requirements.
PasslFail comparison of the curves
The next two sets of data are the point by point comparison of the post-development curve(s) and the
pre-development curve. The Pass/Fail table is helpful in determining compliance since the plotted lines
can be difficult to see at the scales suitable for use in a report. Each point on the post-development
curve has a corresponding fly" value (Flow Rate), and fiX" value (% Time Exceeded). For each point on
the post development curve, the fly" value is used to interpolate the corresponding Percent Time
Exceeded (X) value from the pre-development curve. Then the Post-development Percent Time
Exceeded value is compared to the pre-development Percent Time Exceeded value. Based on the
relative values of each point, pass/fail criteria are determined point by point.
3 See hydromodification limits for exceedance of pre-development values
23
For each set of datal the upper right hand header value shows the name of the file being displayed (ex.
flowDurationPassFaiIMitigated.TXT). The first line of the file shows the name of the SWMM output file
(*.out). The next line shows the time stamp ofthe SWMM file that is being analyzed. The time stamps
of all of the report files should be within a minute or two of each other, otherwise there may have been
tampering with the files. Each report run creates and prints all of the files and reports at one time so all
the time stamps should be very close.
The first column is the zero based number of the point. The next two columns show the post
development "X" and "Y" values. The next column shows the value interpolated between the two
bounding points on the pre-development curve. The next three columns show the true or false values
of the comparison of the two "X" values. The last column shows the resultant pass or fail status of the
point. There are three ways a point can pass. They are:
1. Qpost being outside of the geomorphic ally significant range Qlf to QlO
2. Qpost being less than Q pre
3. Qpost being less than 110% of the value of Qpre if the point is between Qlf and QI0
There are two ways that a point can fail. They are:
1. Qpost being greater than 110% of Qpre ifthe point is between Qlf and QlO
2. If more than 10% of the points are between 100% and 110% of Qpre for the points
between Qlf and QlO
A quick scan down the last column will quickly tell if there are any points that fail.
At the bottom of each set of data are the date stamp of the report to the left, and to the right is the
page number/number of pages for the specific set of data (not the pages of the report!). Each new set
of data has its own page numbering. Between the file name in the header row and the page numbering
in the footer row, the engineer can readily scan the document for the data of interest.
Plan Check Suggestions
As was described under the peak flow section, is the responsibility of the reviewing agency to confirm
that the data sets presented are valid results from consistent calculations, and that any and all results
can be duplicated by manual methods and achieve the same results. In light of these goals, the plan
checker is invited to consider the following tasks as part of the plan check process.
Compare the Data Stamps for Each of the Statistics Files Used In This Analysis.
As was described in the Peak Flows section, all report files should have time stamps that are nearly
identical. If the time values are more than a few minutes apart then the potential for inconsistent
results files should be investigated.

Verify the Flow Rate Counts
For each of the pre, un-mitigate and mitigated flow duration tables, a few randomly selected flow value
counts should be checked against the values taken directly from the SWMM file. This can be done by
opening the corresponding SWMM file, selecting the outfall node, selecting Report>Table>By Object,
Setting the time format to Date/Time, selecting the appropriate node value, and clicking the OK button
to generate a table of the date/time/Total Inflow values. Next step is to click in the left most header
row of the SWMM table which will select the entire table. Now from the main menu select Edit>Copy
To>Clipboard. Now open a new blank sheet in MS Excel (or suitable spread sheet program) select cell
Ai and paste the results from the clipboard into the spread sheet. Now sort the values based on the
Total Inflow column. This will group all the flow values together enabling the number of occurrences of
each value to be counted. At this point the a few (or all) of the counts on the various USGS92;L7d.txt
files can be verified.
Manually Verify That the Percent Exceeded Values (form USGS9217d) are Correctly Calculated
The discharge rates and counts are confirmed as was described above. The top row should be the
smallest runoff value (O.OOcfs usually). Total Periods Exceeding ofthe first line should be the total
number of rainfall records in the study. The percentage of Time Exceeding should be the total periods
Exceeding divided by the total number of rainfall records in the study (100% for the first line). For each
successive discharge rate, the total periods exceeding for the current line should be the total periods
exceeding from the line above minus the number of periods from the line above. The number of
periods and the number of periods exceeding should zero out at the last line.
Compare Plotted Curves to Table Data
Randomly check a few of the plotted points against the values verified above.
Verify by Observation that the plotted values of QlOand Otf are reasonable.
Verify that the correct values for each of these return periods are plotted correctly on the graph.
Development of the Peak Flow Statistics
The peak flow statistics are developed directly from the binary output file produced by theSWMM
program. The site is modeled three ways, Pre-Development, Post-Development-Unmitigated, and Post-
Development-Mitigated. For each of these files a specific time period differentiating distinct storms is
chosen. The SWMM results are extracted and each flow value is queried. The majority of the values for
Southern California sites are zero flow. As each successive record is read, as soon as a non-zero value is
read the time and flow value of that record are recorded as the beginning of an event. The first record is
automatically recorded as the "tentative" peak value. As each successive non-zero value is.read and the
successive flow value is compared to the peak value and the greater value is retained as the peak value
of the storm. As soon as a successive number of zero values equal to the predetermined storm
separation value, then the time value of the last non-zero value is recorded as th~ end of the storm, the
duration of the storm is the difference between the end time and the start time, and the peak value is
recorded as the highest flow value between the start and end times.
25
----------------------------------------,
Once the entire SWMM output file is read all ofthe distinct storm events will have been recorded in a
special list. The storms will be in the order of their occurrence. To develop the peak flow statistics table
the first step is to sort the storms in descending order of the peak flow value. Once the list is sorted
then the relative rank of each storm is assigned with the highest ranking storm being the storm with the
highest peak flow. There are several methods that can be used to determine which storm should be
ranked above another equally valued storm. For the purposes of these studies an Ordinal ranking is
used so that each storm has a unique rank number. Where two or more storms have equal flow values,
the earlier storm is assigned the higher rank. This is done consistently throughout the storm record.
Since we are only looking at peak flow statistics, it is assumed that the relative ranking of individual (but
equal) storms is irrelevant to the calculations.
The exceedance frequency and return period are both computed using the Weibull formula for plotting
position. Therefore, for a specific event the exceedance frequency F and the return period in years Tare
calculated using the following equations4:
and T=n+l/m
where m is the event's rank, nR is the total number of events and n is the number of years under
analysis.
Once the Peak flow statistics table is complete, a plot of Return Frequency vs. peak flow is created. All
three conditions (pre, post and mitigated) are plotted on the same plot.
The Peak Flow Statistics Analysis
The Peak Flow Statistics analysis is composed of the following series of files:
1. The Peak Flow Frequency Plot
2. The Comparison of the Un-Mitigated Peak Flow Curve to the Pre-Development Curve (Pass/Fail)
3. The Comparison of the Mitigated Conditions Curve to the Pre-Development Curve (Pass/Fail)
4. The Peak Flow Statistics Calculation for the Pre-Development Curve.
5. The Peak Flow Statistics Calculation for the Un-Mitigated Curve.
6. The Peak Flow Statistics Calculation for the Mitigated Curve.
The Peak Flow Frequency Plot
The Peak Flow Frequency Curves are the plotting of all three (Pre, Un-Mitigated and Mitigated) sets of
return Period vs peak flow data point pair lists. In addition to these curves horizontal lines are plotted
corresponding to the 010, Os, 02 and Oif (low flow threshold) values. Within the geomorphically
significant range (010 -Oif) one can see a visual representation of the relative positions of the peak flow
curves. The peak flow curves are compared in a North/South (vertical) direction to compare post
development peak flows to pre-development flows. The Pre-Development curve is plotted in blue, the
unmitigated curve is plotted in red, and the mitigated curve is plotted in green. As long as the post

development curve lies below the pre-development curve (mostlyS), the project meets the peak flow
hydromodification requirements.
PasslFail comparison of the curves
The next two sets of data are the point by point comparison of the post-development curve(s) and the
pre-development curve. The Pass/Fail table is helpful in determining compliance since the plotted lines
can be difficult to see at the scales suitable for use in a report. Each point on the post-development
curve has a corresponding "X" value (Recurrence Interval), and "V" value (Peak Flow). For each point on
the post development curve, the "X" value is used to interpolate the corresponding p~ak flow value
from the pre-development curve. Then the Post-development peak flow value is compared to the pre-
development peak flow value. Based on the relative values of each point, pass/fail criteria are
determined point by pOint.
For each set of data, the upper right hand header value shows the name of the file being displayed (ex.
peakFlowPassFailMitigated.TXT). The first line of the file also shows this value. The next line shows the
time stamp of the file that is being analyzed. The time stamps of all of the report files should be within a
minute or two of each other, otherwise there may have been tampering with the files. Each report run
creates and prints all of the files and reports at one time so all the time stamps should be very close. It
should be noted that the SWMM.out files will not have related time stamps since each file is developed
independently.
The first column is the zero based number ofthe pOint. The next two columns show the post
development "X" and "V" values. The next column shows the value interpolated between the two
bounding points on the pre-development curve. The next three columns showthe true or false values
of the comparison of the two tty" values. The last column shows the resultant pass or fail status of the
point. There are three ways a point can pass. Thevare:
1. Point is outside of the geomorphically significant range QlO -Qf
2. Qpost being less than Q pre
3. Qpost being less than 110% of the value of Qpre if the point is between Os and 0,106
There are four ways that a point can fail. They are:
1. Qpost being greater than Qpre if the point is between Qf and Os
2. Qpost being greater than 110% of Qpre if the point is between Qff and QlO ,
3. If more than 10% of the points are between 100% and 110% of Qpre for the points between Os
and Q10
4. If the frequency interval for pOints> 100% of Qpre is greater than 1 year for the points between
Os and Q10
A quick scan down the last column will quickly tell if there are any points that fail.
5 See hydromodification limits for exceedance of pre-development values
6 See section on how a point can fail point number 3 hereon
27
At the bottom of each set of data are the date stamp of the report to the left, and to the right is the
page number/number of pages for the specific set of data (not the pages of the report!). Each new set
of data has its own page numbering. Between the file name in the header row and the page numbering
in the footer row, the engineer can readily scan the document for the data of interest.
The Peak Flow Statistics Calculations
There are three sets of data for the Peak Flow Statistics calculations (Pre-Development, Un-Mitigated,
and Mitigated). As was the case for the pass/fail data, the upper right hand corner of each sheet has the
file name. The first row of the data is the SWMM file name. The second row is the SWMM file time
stamp of the file being analyzed. The 4th, 5th, and 6th rows are the calculated values for Ql0, Os, and 02.
These values are derived by linear interpolation between the nearest bounding points in the listing.
While the relationship between the points in the peak flow analysis is not technically a linear
relationship, the error introduced in using linear interpolation between such relatively close data points
is assumed to be irrelevant. Finally, the footer row shows the report time and the page/number of
pages of the data set.
As was previously discussed, each storm listed was determined by reading the flow values directly from
the binary output file from the SWMM program. The storms were then sorted in descending order of
peak flow values. Then each storm was assigned a unique rank, then the Frequency and Return Period
were calculated using Wei bull formulas. Every discharge value for the entire rainfall record is listed in
each of these lists. It should be noted that the derivation of these peak flow statistics values use full
precision (Le. no rounding off) of the SWMM output values. Since the precision of the calculations may
not be the same as the SWMM program uses, and also the assignment of rank to values of equal peak
flow value may differ slightly from the way SWMM calculates the tables, minor variances in the data
values and/or the order of storms can be expected.
Finally, as was previously stated, the values of the Return Period were plotted vs. the peak flow values
to develop the peak flow frequency curves.
Plan Check Suggestions
As is the responsibility of the reviewing agency, any and all methods should be considered to verify that
the SWMM analysis adequately models the site as far as hydrologic discharge is concerned, and that the
data sets presented are valid results from consistent calculations, and that any and all results can be
duplicated by manual methods and achieve the same results. In light of these goals, the plan checker is
invited to consider the following tasks as part of the plan check process.
Compare the Data Stamps for Each of the Statistics Files Used In This Analysis.
For each set of calculations and report files, the first step of the process is to list out all the files in the
report folder and delete those files. The very first step leaves the reports folder completely empty.
Then as each successive step is performed, the results file is placed in the reports folder. Once all of the
results files are complete, then the report file is compiled using the data directly from the files placed in
the results folder. This means that the time stamps on each of the report files in the report should be
within a minute or two depending on the speed of the computer. If the time values are more than a few
minutes apart then the potential for inconsistent results files should be investigated.

Verify A Few Random Stonn Statistics
For each ofthe Pre, Un-mitigate and Mitigated peak flow statics tables, a few randomly selected storms
should be checked against the values taken directly from the SWMM file. This can be done by opening
the corresponding SWMM file, selecting the outfall node, selecting Report>Table>By Object, Setting the
time format to Date/Time, selecting the appropriate node value, and clicking the OK button to generate
a table ofthe date/time/Total Inflow values. Now scroll down the list to the start date and time of the
randomly selected storm. Verify that the start date, end date, and the highest flow value between the
start and end date correspond to the values shown in the statistics table. Do this for a few storm to
verify that the data corresponds to the SWM M output file. Verify by hand a few of the frequency and
return period values.
Compare Plotted Curves to Table Data
Randomly check a few of the plotted points against the values found in the Peak Flow Frequency rabies.
Verify by Observation that the values of Q 10, Q5, Q2 and Qlf are reasonable.
For each value shown on the reports, verify that the value shown for say Ql0 is in between the next
higher return period and the next lower period. Also verify that the correct values for each of these
return periods are plotted correctly on the peak flow frequency graph.
Manually Verify That the Pass Fail Table Is Correctly Calculated
Select at random several points on each of the pass/fail tables to verify that the values for post X/Y and
interpolated Y look reasonable. Also check that the various test results are shown accurately in the
chart and also the final pass/fail result looks accurate.
Drawdown Time ofBio-retention Surface Ponding
The drawdown time for hydro modification flow control facilities was calculated by assuming a starting
water surface elevation coincident with the peak operating level in the bio-retention facility such ~s the
elevation at the weir or the emergency spillway overflow. The orifice equation was used to determine
the required draw down time for the water to reach the soil surface in each basin. The results of this
calculation for each basin is summarized in Table 3. As can be seen in the table the maximum draw
down time was found to be 57.3 hrs for the existing bioswale (imp 6).
VII. SUMMARY AND CONCLUSION
The proposed project is designated as Hotel and Timeshare Resort and is treated by several bio-
retention basins labeled as IMP-# (Integrated Management Plan).Two point of compliances (POes)
labeled as OUTFALL A and OUTFALL B were analyzed for pre-development, unmitigated and mitigated
post-development conditions. The existing bioswale at the south westerly border of the project was
included in this analysis so that it could be utilized in limiting the runoff for phase "' ofthe project. The
calculations shown in this report have concluded that the existing bioswale, with slight modification to
the riser, will be sufficient, when combined with the proposed bio-retention basins for phase III, to
mitigate the flows created by phase III of the project.
The proposed basins for phase "' were sized based on the required treatment area per LID
requirements. Please refer to the projects SWPP for these sizing calculations.

---------------------
Hydromodification calculations were performed utilizing continuous simulation to size storm water
control facilities. Storm Water Management Model (SWMM) version 5.0 distributed by USEPA was used
to generate computed peak flow recurrence and flow duration series statistics.
The analyzed SWMM runs attached show that the proposed bioretention facilities with variety of orifice
flow control at the base of the gravel storage configured as shown in Figure 1 is in compliance with the
HMP and SUSMP.
At OUTFALL A, the flow duration curve on the following page shows without mitigation this project will
increase the duration of the geomorphically significant flow after development about 82.9 hours
(.947%x365 daysx24 hour/day = 82.9 hours) versus the existing condition 65.4 hours
(0.747%x365daysx24 hour/day = 65.4 hours).
With the proposed square footage bio-retentions and the low flow restrictors configured as shown in
Figure 1 the duration of the flow decreases to 55.6 hours (0.635%x365daysx24 hour/day =55.6 hours).
An increase less than 10% is allowable.
At OUTFALL B, the flow duration curve on the following page shows without mitigation this project will
increase the duration of the geomorphically significant flow after development to about 26.3 hours
(0.301%x365 daysx24 hour/day = 26.3 hours) versus the existing condition 12.6 hours
(0.144%x365daysx24 hour/day = 12.6 hours).
With the proposed square footage bio-retentions and the low flow restrictors configured as shown in
Figure 1 the duration of the flow decreases to 12.2 hours (0.139%x365daysx24 hour/day =12.2 hours).
An increase less than 10% is allowable.
Therefore, this study has demonstrated that the proposed optimized bio-retention basin is sufficient to
meet the current HMP and SUSMP criteria. The depth of the amended layers are tabularized as follows:

The Mitigated Conditions peak flow frequency curve is composed of 177 points. Of the points, 1 point(s) are above
the flow control upper limit (Q10), 46 point(s) are below the low flow threshold value (Qlf). Of the points within
the flow control range (Qlf to Q10), 130 point(s) have a lower peak flow rate than pre-development conditions.
These points all pass. There are no points that failed, therefore the unmitigated conditions peak flow
requirements have been met.
---Unmitigated Conditions---
The Unmitigated Conditions flow duration curve is composed of 433 points. Of the points, 22 point{s) are above
the flow control upper limit (Q10), 45 point(s) are below the low flow threshold value (Qlf). Of the pOints within
the flow control range (Qlf to Q1O), 0 point(s) have a lower duration than pre-development conditions. These
points all pass. There are 366 point(s) (within the flow control range) that the post-development condition
exceeded the pre-development condition by MORE than 10%. If any number of points in the flow control range
exceed pre-development values by MORE than 10% then the study FAILS flow control requirements. Since there
are 366 points that failed (ie more than 0), the unmitigated conditions flow duration requirements have NOT been
met.
The Unmitigated Conditions peak flow frequency curve is composed of 323 points. Of the points, 22 point(s) are
above the flow control upper limit (Q10), 34 point(s) are below the low flow threshold value (Qlf). Of the points
within the flow control range (Qlf to Q10), 51 point(s) have a lower peak flow rate than pre-development
conditions. These pOints all pass. There are 184 point(s) from Qlf to Q5 that the post-developrnent peak flow rate
exceeded the pre-development flow rates. If any number of points from Qlf to Q5 exceed pre-development vCllues
(at all), the study fails. There are 32 point{s) from Q5 to Q10 that the post-development peCik flow rate exceeds
the pre-development flow rates by greater than 10%. If any number of points from Q5 tOoQ10 exceed 110% of the
pre-development values, the study fails. Since there are 216 points that failed (ie more than 0), the unmitigated
conditions peak flow requirements have NOT been met.

---Mitigated ,Conditions---
The Mitigated Conditions flow duration curve is composed of 89 points. Of the points, 0 point(s) are above the
flow control upper limit (Q1O), 13 point(s) are below the low flow threshold value (Qlf). Of the points within the
flow control range (Qlf to Ql0), 76 point(s) have.a lower duration than pre-development conditions. These points
all pass. There are no points that failed, therefore the unmitigated conditions flow duration requirements have
been met.

The Mitigated Conditions peak flow frequency curve is composed of 103 points. Ofthe points, 0 point(s) are above
the flow control upper limit (Ql0), 15 point(s) are below the low flow threshold value (Qlf). Of the points within
the flow control range (Qlf to Ql0), 88 point(s) have a lower peak flow rate than pre-development conditions.
These pOints all pass. There are no pOints that failed, therefore the unmitigated conditions peak flow
requirements have been met.
---Unmitigated Conditions---
The Unmitigated Conditions flow duration curve is composed of 130 points. Of the points, 1 polnt(s) are above the
flow control upper limit (Ql0), 13 point(s) are below the low flow threshold value (Qlf). Of the points within the
flow control range (Qlfto Ql0), 77 point(s) have a lower duration than pre-development conditions. These points
all pass. There are 19 point(s) (within the flow control range) that the post-development condition exceeded the
pre-development condition by MORE than 10%. If any number of points in the flow control range exceed pre-
development values by MORE than 10% then the study FAILS flow control requirements. There are 20 point(s) that
the post-development condition exceeded the pre-development conditions by LESS than 10%. This accounts for
15.4% of the curve length, which is greater than the 10% allowed. Therefore the study FAILS flow control
requirements. Since there are 39 points that failed (ie more than 0), the unmitigated conditions flow duration
requirements have NOT been met.
The Unmitigated Conditions peak flow frequency curve is composed of 142 points. Of the points, 1 point(s) are
above the flow control upper limit (Ql0), 13 point(s) are below the low flow threshold value (Qlf). Of the points
within the flow control range (Qlf to Ql0), 126 point(s) have a lower peak flow rate than pre-development
conditions. These points all pass. There are 2 point(s) from Qlf to Q5 that the post-development peak flow rate
exceeded the pre-development flow rates. If any number of points from Qlf to Q5 exceed pre-development values
(at all), the study fails. Since there are 2 points that failed (ie more than 0), the unmitigated conditions peak flow
requirements have NOT been met.

Cooperative Soil Survey,
a joint effort of the United
States Department of
Agriculture and other
Federal agencies, State

Stations, and local
participants
Custom Soil Resource
Report for
San Diego County
Area, California

Preface
Soil surveys contain information that affects land use planning in survey areas. They
highlight soil limitations that affect various land uses and provide information about
the properties of the soils in the survey areas. Soil surveys are designed for many
different users, including farmers, ranchers, foresters, agronomists, urban planners,
community officials, engineers, developers, builders, and home buyers. Also,
conservationists, teachers, students, and specialists in recreation, waste disposal,
and pollution control can use the surveys to help them understand, protect, or enhance
the environment.
Various land use regulations of Federal, State, and local governments may impose
special restrictions on land use or land treatment. Soil surveys identify soil properties
that are used in making various land use or land treatment decisions. The information
is intended to help the land users identify and reduce the effects of soil limitations on
various land uses. The landowner or user is responsible for identifying and complying
with existing laws and regulations.
Although soil survey information can be used for general farm, local, and wider area
planning, onsite investigation is needed to supplement this information in some cases.
Examples include soil quality assessments (http://www.nrcs.usda.gov/wps/portal/
nrcs/main/soils/health/) and certain conservation and engineering applications. For
more detailed information, contact your local USDA Service Center (http://
offices.sc.egov.usda.gov/locator/app?agency=nrcs) or your NRCS State Soil
Scientist (http://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/contactus!?
cid=nrcs 142p2_ 053951).
Great differences in soil properties can occur within short distances. Some soils are
seasonally wet or subject to flooding. Some are too unstable to be used as a
foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic
tank absorption fields. A high water table makes a soil poorly suited to basements or
underground installations.
The National Cooperative Soil Survey is a joint effort of the United States Department
of Agriculture and other Federal agencies, State agencies including the Agricultural
Experiment Stations, and local agencies. The Natural Resources Conservation
Service (NRCS) has leadership for the Federal part of the National Cooperative Soil
Survey.
Information about soils is updated periodically. Updated information is available
through the NRCS Web Soil Survey, the site for official soil survey information.
The U.S. Department of Agriculture (USDA) prohibits discrimination in all its programs
and activities on the basis of race, color, national origin, age, disability, and where
applicable, sex, marital status, familial status, parental status, religion, sexual
orientation, genetic information, political beliefs, reprisal, or because all or a part of an
individual's income is derived from any public assistance program. (Not all prohibited
bases apply to all programs.) Persons with disabilities who require alternative means

How Soil Surveys Are Made
Soil surveys are made to provide information about the soils and miscellaneous areas
in a specific area. They include a description of the soils and miscellaneous areas and
their location on the landscape and tables that show soil properties and limitations
affecting various uses. Soil scientists observed the steepness, length, and shape of
the slopes; the general pattern of drainage; the kinds of crops and native plants; and
the kinds of bedrock. They observed and described many soil profiles. A soil profile is
the sequence of natural layers, or horizons, in a soil. The profile extends from the
surface down into the unconsolidated material in which the soil formed or from the
surface down to bedrock. The unconsolidated material is devoid of roots and other
living organisms and has not been changed by other biological activity.
Currently, soils are mapped according to the boundaries of major land resource areas
(MLRAs). MLRAs are geographically associated land resource units that share
common characteristics related to physiography, geology, climate, water resources,
soils, biological resources, and land uses (USDA, 2006). Soil survey areas typically
consist of parts of one or more MLRA.
The soils and miscellaneous areas in a survey area occur in an orderly pattern that is
related to the geology, landforms, relief, climate, and natural vegetation of the area.
Each kind of soil and miscellaneous area is associated with a particular kind of
landform or with a segment of the landform. By observing the soils and miscellaneous
areas in the survey area and relating their position to specific segments of the
landform, a soil scientist develops a concept, or model, of how they were formed. Thus,
during mapping, this model enables the soil scientist to predict with a considerable
degree of accuracy the kind of soil or miscellaneous area at a specific location on the
landscape.
Commonly, individual soils on the landscape merge into one another as their
characteristics gradually change. To construct an accurate soil map, however, soil
scientists must determine the boundaries between the soils. They can observe only
a limited number of soil profiles. Nevertheless, these observations, supplemented by
an understanding of the soil-vegetation-Iandscape relationship, are sufficient to verify
predictions of the kinds of soil in an area and to determine the boundaries.
Soil scientists recorded the characteristics of the soil profiles that they studied. They
noted soil color, texture, size and shape of soil aggregates, kind and amount of rock
fragments, distribution of plant roots, reaction, and other features that enable them to
identify soils. After describing the soils in the survey area and determining their
properties, the soil scientists assigned the soils to taxonomic classes (units).
Taxonomic classes are concepts. Each taxonomic class has a set of soil
characteristics with precisely defined limits. The classes are used as a basis for
comparison to classify soils systematically. Soil taxonomy, the system of taxonomic
classification used in the United States, is based mainly on the kind and character of
soil properties and the arrangement of horizons within the profile. After the soil
scientists classified and named the soils in the survey area, they compared the
5

individual soils with similar soils in the same taxonomic class in other areas so that
they could confirm data and assemble additional data based on experience and
research.
The objective of soil mapping is not to delineate pure map unit components; the
objective is to separate the landscape into landforms or landform segments that have
similar use and management requirements. Each map unit is defined by a unique
combination of soil components and/or miscellaneous areas in predictable
proportions. Some components may be highly contrasting to the other components of
the map unit. The presence of minor components in a map unit in no way diminishes
the usefulness or accuracy of the data. The delineation of such landforms and
landform segments on the map provides sufficient information for the development of
resource plans. If intensive use of small areas is planned, onsite investigation is
needed to define and locate the soils and miscellaneous areas.
Soil scientists make many field observations in the process of producing a soil map.
The frequency of observation is dependent upon several factors, including scale of
mapping, intensity of mapping, design of map units, complexity of the landscape, and
experience of the soil scientist. Observations are made to test and refine the soil-
landscape model and predictions and to verify the classification of the soils at specific
locations. Once the soil-landscape model is refined, a significantly smaller number of
measurements of individual soil properties are made and recorded. These
measurements may include field measurements, such as those for color, depth to
bedrock, and texture, and laboratory measurements, such as those for content of
sand, silt, clay, salt, and other components. Properties of each soil typically vary from
one point to another across the landscape.
Observations for map unit components are aggregated to develop ranges of
characteristics for the components. The aggregated values are presented. Direct
measurements do not exist for every property presented for every map unit
component. Values for some properties are estimated from combinations of other
properties.
While a soil survey is in progress, samples of some of the soils in the area generally
are collected for laboratory analyses and for engineering tests. Soil scientists interpret
the data from these analyses and tests as well as the field-observed characteristics
and the soil properties to determine the expected behavior of the soils under different
uses. Interpretations for all of the soils are field tested through observation of the soils
in different uses and under different levels of management. Some interpretations are
modified to fit local conditions, and some new interpretations are developed to meet
local needs. Data are assembled from other sources, such as research information,
production records, and field experience of specialists. For example, data on crop
yields under defined levels of management are assembled from farm records and from
field or plot experiments on the same kinds of soil.
Predictions about soil behavior are based not only on soil properties but also on such
variables as climate and biological activity. Soil conditions are predictable over long
periods of time, but they are not predictable from year to year. For example, soil
scientists can predict with a fairly high degree of accuracy that a given soil will have
a high water table within certain depths in most years, but they cannot predict that a
high water table will always be at a specific level in the soil on a specific date.
After soil scientists located and identified the significant natural bodies of soil in the
survey area, they drew the boundaries of these bodies on aerial photographs and
identified each as a specific map unit. Aerial photographs show trees, buildings, fields,
roads, and rivers, all of which help in locating boundaries accurately.

Map Unit Descriptions
The map units delineated on the detailed soil maps in a soil survey represent the soils
or miscellaneous areas in the survey area. The map unit descriptions, along with the
maps, can be used to determine the composition and properties of a unit.
A map unit delineation on a soil map represents an area dominated by one or more
major kinds of soil or miscellaneous areas. A map unit is identified and named
according to the taxonomic classification of the dominant soils. Within a taxonomic
class there are precisely defined limits for the properties ofthe soils. On the landscape,
however, the soils are natural phenomena, and they have the characteristic variability
of all natural phenomena. Thus, the range of some observed properties may extend
beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic
class rarely, if ever, can be mapped without including areas of other taxonomic
classes. Consequently, every map unit is made up of the soils or miscellaneous areas
for which it is named and some minor components that belong to taxonomic classes
other than those of the major soils.
Most minor soils have properties similar to those of the dominant soil or soils in the
map unit, and thus they do not affect use and management. These are called
noncontrasting, or similar, components. They mayor may not be mentioned in a
particular map unit description. Other minor components, however, have properties
and behavioral characteristics divergent enough to affect use or to require different
management. These are called contrasting, or dissimilar, components. They generally
are in small areas and could not be mapped separately because of the scale used.
Some small areas of strongly contrasting soils or miscellaneous areas are identified
by a special symbol on the maps. If included in the database for a given area, the
contrasting minor components are identified in the map unit descriptions along with
some characteristics of each. A few areas of minor components may not have been
observed, and consequently they are not mentioned in the descriptions, especially
where the pattern was so complex that it was impractical to make enough observations
to identify all the soils and miscellaneous areas on the landscape.
The presence of minor components in a map unit in no way diminishes the usefulness
or accuracy of the data. The objective of mapping is not to delineate pure taxonomic
classes but rather to separate the landscape into landforms or landform segments that
have similar use and management requirements. The delineation of such segments

on the map provides sufficient information for the development of resource plans. If
intensive use of small areas is planned, however, onsite investigation is needed to
define and locate the soils and miscellaneous areas.
An identifying symbol precedes the map unit name in the map unit descriptions. Each
description includes general facts about the unit and gives important soil properties
and qualities.
Soils that have profiles that are almost alike make up a soil series. Except for
differences in texture of the surface layer, all the soils of a series have major horizons
that are similar in composition, thickness, and arrangement.
Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity,
degree of erosion, and other characteristics that affect their use. On the basis of such
differences, a soil series is divided into soil phases. Most of the areas shown on the
detailed soil maps are phases of soil series. The name of a soil phase commonly
indicates a feature that affects use or management. For example, Alpha silt loam, 0
to 2 percent slopes, is a phase of the Alpha series.
Some map units are made up of two or more major soils or miscellaneoUs areas.
These map units are complexes, associations, or undifferentiated groups.
A complex consists of two or more soils or miscellaneous areas in such an intricate
pattern or in such small areas that they cannot be shown separately on the maps. The
pattern and proportion of the soils or miscellaneous areas are somewhat similar in all
areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example.
An association is made up of two or more geographically associated soils or
miscellaneous areas that are shown as one unit on the maps. Because of present ()r
antiCipated uses of the map units in the survey area, it was not considered practical
or necessary to map the soils or miscellaneous areas separately. The pattern and
relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha-
Beta association, 0 to 2 percent slopes, is an example.
An undifferentiated group is made up of two or more soils or miscellaneous areas that
could be mapped individually but are mapped as one unit because similar
interpretations can be made for use and management. The pattern and proportion of
the soils or miscellaneous areas in a mapped area are not uniform. An area can be
made up of only one of the major soils or miscellaneous areas, or it can be made up
of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example.
Some surveys include miscellaneous areas. Such areas have little or no soil material
and support little or no vegetation. Rock outcrop is an example.
