SECTION 1
INTRODUCTION AND BACKGROUND
: Storm Water Pollution Prevention Plan - General
This Stormwater Pollution Prevention Plan (SWPPP) is prepared in accordance with the California
: State Water Resources Control Board (Water Quality Order) Order No. 99-08-DWQ, National
I Pollutant Discharge Elimination System (NPDES) General Permit No, CAS000002, This SWPPP
: complies with Best Available Technology Economically Achievable (BAT) and Best Conventional
; Pollutant Control Technology (BCT) to reduce or eliminate stormwater pollution from areas of a
,construction activity. The SWPPP document is certified in accordance with the signatory
I requirements of Standard Provisions C,9 in the State General Construction Stormwater Permit
,(Permit).
. The objectives of this SWPPP are to (1) identify the sources of sediment and other pollutants from
I the construction site that affect the quality of storm water discharges and (2) to describe the
: practices to reduce sediment and other pollutants in stormwater discharges generated from the
: construction site.
. The SWPPP and the recommended controls will be implemented prior to commencing the
: construction activity, In addition, the SWPPP shall bekept on site and made available upon request
, of a representative of the Regional Water Quality Board and/or Riverside County Flood Control and
'Water Conservation District (RCFC&WCD). The Regional Water Quality Board and/or RCFC&WCD
'may notify SPT - Holdings, LLC if this SWPPP does not meet one or more of the minimum
, requirements of the Permit. Within 30 days of notice, SPT - Holdings, LLC shall submit a time
: schedule for implementing the changes, per the minimum requirements of the Permit, to the
! Regional Water Quality Control Board and/or RCFC&WCD, and specify when compliance will be
; achieved, After making the required changes, SPT - Holdings, LLC shall certify that the changes
, have been made.
. This SWPPP will be amended whenever there is a change in ownership, construction or operation
,which may affect the discharge of significant quantities of pollutant to surface waters, ground water,
. or a municipal separate storm drain system, This SWPPP will also be amended if it is in violation
of any condition of the Permit, or has not achieved the general objectives of reducing pollutants in
I the storm water discharge from the construction activity site, Each amendment will be identified in
, Section 16 of this SWPPP with the appropriate information, along with a description or discussion
of the nature of the revisions.
I Implementation
The general work program which accompanies the implementation of the SWPPP is indicated on
~ the following logic diagram, The SWPPP must be implemented prior the actual construction
: commencing, The initial element of the SWPPP to be completed is the training

or education program to ensure that the construction personnel are thoroughly aware of the overall
stormwater pollution management program. The recommended control measures are then
constructed and installed as required depending on the phasing of the construction, The program
. outlined in the SWPPP will be administered by the discharger until construction is complete, If
, ongoing construction involves a change in ownership, the new owner must accept, maintain and
, amend this SWPPP as required,
Termination
. The owner or discharger may cancel or terminate coverage under the Permit by submitting to the
, State Water Board, certification that the following has occurred:
1, The construction activity has been completed;
: 2, All elements of the SWPPP have been completed;
: 3. Construction and equipment maintenance wastes have been disposed of properly;
.4. The site is in compliance with all local storm water management requirements including
erosion/ sediment control requirements, policies, and guidelines.
~ ChanQe in Ownership
The discharger may also cancel coverage under this Permit when ownership of all or a portion of
the project has been transferred, The coverage of the permit is not transferable to any person and
the new owner must submit a NOI to be authorized to discharge under the permit. The new owner
. shall be responsible for implementing the applicable portions of the SWPPP pertaining to the site,
. specifically the monitoring and reporting requirements, The original owner must inform the new
. owner of the requirements for filing a NOI and provide the new owner with a copy of the permit.
; Penalties
. Violation of the Permit conditions is covered by Section 309 of the Clean Water Act (CWA). This
. section provides for significant penalties for any person who violated a permit condition
implementing Section 301, 302, 306, 307, 308, 318, or 405 of the CWA or any permit condition or
limitation implementing any such section in a permit issued under section 402, Any person who
. violates any condition of this permit is subject to a civil penalty not to exceed $25,000 per day of
such violation, as well as any other appropriate sanction by Section 309 of the CWA.
. Sanctions are also possible for falsification of reporting information on the inspection records and
certifications, Section 309 (c) (4) of the CWA provides that any person who knowingly makes any
false material statement, representation, or certification in any record or their document submitted
. or required to be maintained under this Permit, including reports of compliance or noncompliance
shall, upon conviction, be punished by a fine of not more than $10,000 or by imprisonment for not

: SOURCE IDENTIFICATION: SITE DESCRIPTION
I Construction Site Characteristics
The Parcel "E" project includes the excavation and compaction of 12,500 CY of earthwork from
within the 3,1 acre site, The percentage of impervious surface of the site following construction will
! be about 70 percent. The estimated runoff coefficient after construction is completed will be 0,70,
There is currently no controlled vegetation other than seasonal weed growth on the site.
,According to the Riverside County Flood Control and Water Conservation District (RCFC&WCD)
I Hydrology Manual (1978) soil group designations, existing soils in this area consist of mostly Soil
: Group "B". Group "B" soils have moderate infiltration rates when thoroughly wetted and consisting
. chiefly of moderately deep to deep, moderately well to well drained soils with moderately fine to
, moderately coarse textures, These soils have a moderate rate of water transmission,
. There is currently no evidence of any disposed pollution at the site or its tributary offsite area, This
: conclusion has been prompted by the vacant land use at the site. There is no indication of surface
disposal, treatment, storage and/or spill of any kind of waste at the construction site,

ExistinQ Site DrainaQe Patterns
The existing storm drain facilities for the Parcel "E" project consists of a catch basin and storm drain
: system within Margarita Road, The onsite drainage sheet flows to this catch basin. The onsite
,drainage generally flows westerly in this system via Long Canyon Creek to Ynez Road, The
, drainage proceeds under Ynez Road and 1-15 to Murrieta Creek and then to the Santa Margarita
I River which outlets at the Pacific Ocean,
I Construction Areas
, The access to the construction site is from Margarita Road and North General Kearny Road, as
: shown on Exhibit "A", Page 7, Access to graded areas are through graded roadways. Construction
, material loading and unloading will be through Margarita Road.
I Equipment StoraQe. CleaninQ. and Maintenance Areas
! Equipment storage, cleaning and maintenance during construction shall be accomplished onsite.
,An area of the site at the southeasterly corner of Margarita Road and North General Kearny Road
, has been designated for this purpose,
; Onsite StoraQe and Disposal of Construction Materials
, Construction material shall be disposed of in covered steel refuse drums on a daily basis and stored
in a covered area at the material storage areas, Lids should be closed at all times, The disposed
. construction material shall be transported to the nearest landfill after completion of the construction
; activities, Sanitary facilities will be convenient and well maintained, Useful construction materials
,will be salvaged and recycled if possible,
I Potential pollutants other than sediment associated with the construction activity will either be stored
in enclosed sheds or some form of covered storage area to avoid contact with rainfall. The storage
: areas will be regularly monitored for leaks or spills,
Wastes generated by the construction activity will be stored in central locations, Waste containers
,will be labeled and located in a covered area, Lids should be closed at all times, Sanitary facilities
,will be convenient and well maintained, Useful construction materials will be salvaged and recycled
if possible.

~ SECTION 4
:SOURCE IDENTIFICATION: POLLUTANT SOURCES
I Pre-existinq Pollutant Sources
1, No significant materials have been spilled, leaked, or otherwise accidentally released in
significant quantities onto the construction site. This assessment is based upon the best
information available including historic data for the site obtained during the initial
investigations, environmental review, and the final design process, In addition, the
geotechnical investigations performed on the site did not encounter any evidence of existing
pollutant sources. No "significant materials in significant quantities" includes no toxic
chemicals, listed in Code of Federal Regulation (40 CFR 372), requiring reporting on EPA
Form R; and no oil or hazardous substances in excess of reportable quantities, as specified
in 40 CFR 110,117, and 302.
I Pollutants thatiMav Affect Stormwater Qualitv
The most economical and effective control for pollutants other than sediment generated on
construction site, is through the exercise of good "housekeeping" practices and an awareness of
,the need for compliance with the regulatory requirements. Common construction practices may
'have the potential to cause pollution other than erosion and sedimentation, There may also be
: discharges of nonstormwater required as part of the construction process and these have been
identified in this SWPPP,
'1. Petroleum Products: Oils, fuels, diesel oil, kerosene, lubricating oils, grease, and asphalt
paving,
; Recommended Control Measures: Retain the sediment containing the oil on the construction site,
'Soil erosion and sediment control practices will accomplish this, Dumping of petroleum wastes into
: storm drain or sewer systems is strictly prohibited and could result in criminal fines. For additional
information on disposal of petroleum products see Section 7, WASTE MANAGEMENT AND
: DISPOSAL, of this SWPPP,
: General guidelines for storing petroleum products include the following:
I. Store products in weather resistant sheds where possible
,. Create shelter around the area with cover and wind protection
, . Line the storage area with a double layer of plastic sheeting
'. Create impervious barrier around the perimeter
, . Capacity of the bermed area should be 110 percent of the container
, . Label all products clearly
, . Keep tanks off the ground
, . Post information for procedures in case of spills.
, . Materials for cleaning up spills should be kept on-site and easily available.
, . Spills should be cleaned up immediatelv and the contaminated material properly disposed,
, . All storage sheds, dumpsters, or other storage facilities should be regularly monitored for
leaks and repaired as necessary,

: Spill Response:
, . Small spills are wiped up using dry rags, Used rags are disposed of properly.
, . Medium spills (those too large to wipe up) are contained as soon as possible, Liquids are
soaked up using a dry absorbent material such as kitty litter, The used absorbent is then
swept up and disposed of properly,
'. Large spills are contained as soon as possible, If the spill is not "double contained" and has
the potential to flow into drainage inlets on the project, then the inlets should be temporarily
plugged, If the spilled material is hazardous then contact the Fire Department for a
Hazardous Material Response Team
: 2. Nutrients: Fertilizers
: Recommended Control Measures: Pollution minimized by working fertilizers and liming materials
into the soil to depths of 4 to 6 inches, and by the proper timing of the application, Control of
'nutrient pollution from hydroseeding operations can be achieved by applying the required quantity
'of fertilizer in more than one operation. Care should be taken to use only the minimum amount of
: phosphorus needed, The importation of topsoil near sensitive surface waters is better than utilizing
'fertilizers or heavily liming the subsoil since the addition of lime can affect the pH of the runoff,
: 3. Additional Construction Chemicals: Paints, acids for cleaning masonry surfaces,
,cleaning solvents, asphalt prOducts and concrete curing compounds.
: Recommended Control Measures: A large percentage ofthe pollutants can be effectively controlled
through the soil and erosion control practices, see Section 6 of this SWPPP, Use only the
recommended amount of these materials and apply them in the proper manner, Good
housekeeping is the most important means of controlling pollution. The proper disposal of these
,chemicals are discussed in Section 7, WASTE MANAGEMENT AND DISPOSAL of this SWPPP,

Existina Stormwater Pollution Controls
'The existing stormwater pollution controls at the site consist of: rows of sandbags at the toes of
,slopes; sandbag check dams at catch basin inlets; grading to drain away from slopes, concrete
'terrace and downdrains at slopes; sandbag velocity reducers in graded streets; desilting basins, and
'vegetation of slopes in constructed areas, The City of Temecula is the local agency responsible
'for administering grading and erosion control through the processing of grading permits, The critical
I requirements of the City ofTemecula for erosion control include the following measures which have
I been implemented on the project erosion control plan and are included within this SWPPP in
: Section 12, FACILITY EROSION CONTROL PLAN:
, . Equipment and workers for emergency work shall be made available at all times during the
rainy season, Necessary materials shall be available onsite and stockpiled at convenient
locations to facilitate rapid construction of temporary devices when rain is imminent.
, . All removable protective devices shown shall be in place at the end of each working day
when the 5-day rain probability forecast exceeds 40%,
, . After a rainstorm, all silt and debris shall be removed from check berms, silt fences, and
desilting basins, etc,
, . Graded areas around the tract perimeter must drain away from the face of slope at the
conclusion of each working day,
I. Desilting basins are to be constructed as grading of individual grading areas are complete
per rough grading plans.
,. Temporary erosion protection is required for manufactured slopes prior to permanent
planting.
I. No obstruction or disturbance of natural drainage courses or existing storm drain inlets shall
occur during the raining season, unless adequate temporary/permanent drainage facilities
have been approved and installed to carry surface water to the nearest practical street,
storm drain or natural water course,
I. The Contractor shall conduct his operations in such a manner that storm runoff will be
contained within the project or channeled into the storm drain system which serves the
runoff area, Storm runoff from one area shall not be allowed to divert to another runoff area,
,. Slopes constructed prior to October 1 st shall be treated for erosion control prior to October
15. Slopes constructed after October 1 st shall be treated for erosion control as the
construction of slope progresses in increments of 25 feet or less measured vertically.
I. Fill areas while being brought up to grade and during periods of completion prior to final
grade, shall be protected by various measures to eliminate erosion and the siltation of
downstream facilities and adjacent areas, These measures may include, but shall not be
limited to: temporary downdrains, either in the form of pipes or paved ditches with protected
outfall areas; graded berms around areas to eliminate erosion offill slopes by surface runoff;
confined ponding areas to desilt runoff; temporary check dams in toe of slope ditches to

desilt runoff; protection such as sand bags around inlets which have not been brought up
to grade; and earth berms and appropriate grading to direct drainage away from the edge
of the top of slopes shall be constructed and maintained on those fill areas where earthwork
operations are not in progress.
, . Clearing and grubbing should be limited to areas that will receive immediate grading,
Erosion control measures will be required to protect areas which have been cleared and
grubbed prior to grading operation, and which are subject to runoff during the period from
the rainy season, These measures may include, but shall not be limited to, graded ditches;
brush barriers and silt fences, Care shall be exercised to preserve vegetation beyond limits
of grading,
'The project is tributary to an existing municipal storm drain/flood control system which is maintained
by the local agency RCFC&WCD, The municipal storm drain system is covered by the municipal
'NPDES Stormwater Permit No, CA S000002 which the agency is a permittee, In compliance with
,the conditions of the permit, a Drainage Area Management Plan has been prepared and is being
implemented, The plan identifies a wide range of Best Management Practices (BMP's) and control
techniques, The current project attempts to ensure that goals of the DAMP are implemented to the
maximum extent possible,

I EROSION AND SEDIMENT CONTROL PRACTICES
'The major principles of erosion and sediment control which have been applied in the development
,of this SWPPP for the construction project include the following:
'. Minimize the extent of the disturbed area and duration of exposure
'. Stabilize and protect disturbed areas as soon as possible
'. Keep runoff velocities low
'. Protect disturbed areas from runoff
'. Retain sediment within the construction site area
'. Implement a thorough maintenance and follow-up program
I Recommended Practices
The erosion and sediment control practices described below address general areas of soil
,stabilization, erosion control structures, and practices to control sediment in storm water, sediment
on adjoining roadways, and wind erosion,
'1. "Surface Roughening": Preservation of a ,rough soil surface with horizontal depression
created by operating a tiller or other suitable equipment on the contour or by leaving slopes
in a roughened condition by not fine grading them.
Applicable Conditions: All slopes greater than 3: 1, and greater than 5 vertical feet, require
surface roughening; either stair step grading, grooving, furrowing, or tracking if they are to
be stabilized with vegetation,
Design:
.
Graded areas with slopes greater then 3: 1 but less than 2: 1 should
be roughened before seeding, This can be accomplished in a variety
of ways, including "track walking," or driving a crawler up and down
the slope, leaving a pattern of cleat prints parallel to slope contours,
.
Graded areas steeper than 2: 1 should be stair-stepped with
benches. The stair stepping will help vegetation become more
established and also trap eroded soil from the slopes above,

at points of vehicular ingress and egress on a construction site,
Applicable Conditions: Wherever traffic will be leaving a construction site and moving
directly onto a public road or other paved areas
Design:
.
Material should be quarry spall 4 to 8 inches in size or 2 - 3 inch
washed stone aggregate
.

material used and 100 feet in length for sites more than one acre;
and reduced to 50 feet in length for sites less than one acre,
.
Width shall be the full width of the vehicle ingress and egress area
(minimum of 20 feet)

Figure 2 - Gravel entrance/exit minimizes vehicle tracking of sediment from the
construction site onto existing streets
. Use geotextile fabrics to improve the stability of the foundation for the gravel
road base,
: 3. "Temporary Seeding": Planting rapid growing annual grasses, small grains or legumes
to provide initial, temporary cover for erosion control on disturbed areas,
Applicable Conditions: On any cleared, unvegetated, or sparsely vegetated soil surface
where vegetative cover is needed for less than one year, Applications of this practice
include diversions, dams, sediment basin, temporary road banks and stockpiles.
Design:
.
Complete grading before preparing seedbeds and installing all
necessary erosion control practices, such as dikes and basins,
Minimize steep slopes since this makes seed bed preparation difficult
and increases the erosion hazard,
.
Fertilizer - Base application rates on soil tests. When these are not
possible, apply a 10-10-10 grade fertilizer at 700-1 ,000 Ib/acre, Both
fertilizer and lime should be incorporated into the top 4-6 inches of

soil. If a hydraulic seeder is used, do not mix seed and fertilizer more
than 30 minutes before application.
. Seeding - Hydroseeded mixtures should include a wood fiber
(cellulose) mulch,
,4. "Permanent Seeding": The establishment of perennial vegetative cover on disturbed
areas,
Applicable Conditions: Graded, final graded or cleared areas where permanent
vegetative cover is needed to stabilize the soil. Areas which will not be brought to final
grade for a year or more, Vegetation-lined channels. Retention or detention ponds as
required.
Design:
.
Vegetation cannot be expected to supply an erosion control cover
and prevent slippage on a soil that is not stable due to its texture,
structure, water movement, or excessive slope,
. Seeding should be done immediately after final shaping, except
during the period of October 1 through April 1, when the site should
be protected by mulching or plastic covering until the next seeding
period,
. Permanent vegetation may be in the form of grass-type growth by
seeding or sodding, or it may be trees or shrubs, or a combination of
these, Establishing this cover may require the use of supplemental
materials, such as mulch or jute netting,
'''Sodding'': Stabilizing fine-graded disturbed areas by establishing permanent grass stands with
'sod,
Applicable Conditions: Disturbed areas which require immediate vegetative cover.
Waterways carrying intermittent flow, where immediate stabilization or aesthetics are factors
and other locations which are particularly suited to stabilization with sod,
Design:
Shape and smooth the surface to final grade in accordance with the
approved grading plan.
.
.
Add lime to reach a soil pH value of 6,5 (based on soil tests),
.
Fertilize according to a soil test or in the absence of a test use
available nitrogen, phosphorus and potash as prescribed for
permanent seeding, Use fertilizers that are not highly soluble,
.
Work lime and fertilizer into the soil 1 to 2 inches deep and smooth
the surface,

. Lay strips of sod beginning at the lowest area to be sodded and
perpendicular to the direction of water flow, Wedge strips securely
in place, Square the ends of each strip to provide for a close, tight
fit. Stagger joints at least 12 inches. Staple if on steep slopes,
. Roll the sodded area and irrigate,
. When sodding is carried out in alternating strips, or other patterns,
seed the areas between the sod immediately after sodding.
. Sod should be free of weeds and be of uniform thickness (Approx. 1
in,) and should have a dense root mat for mechanical strength,
5. "Plastic Covering or Sheeting:" The covering with clear plastic sheeting of bare areas
which need immediate protection from erosion.
Applicable Conditions: Disturbed areas which require immediate erosion protection.
Areas seeded during the time period from November 1 to March 1, Plantings at this time
require clear plastic covering for germination and protection from heavy rains,
Design:
.
Clear plastic sheeting shall have a minimum thickness of 6 mil and
meet the requirements of the Standard Specifications for Public
Works Construction,
.
Covering shall be installed and maintained tightly in place by using
sandbags or tires on ropes with a maximum 10 foot grid spacing in
all directions, All seams shall be taped or weighted down full length
and there shall be at least a 1 to 2 foot overlap of all seams, Seams
should then be rolled and staked or tied.
.
Covering shall be installed immediately on areas seeded between
October 1 to April 1 , and remain until vegetation is firmly established,
.
When the covering is used on unseeded slopes, it shall be left in
place until the next seeding period.
.
Sheeting should be toed in at the tope of the slope to prevent surface
flow beneath the plastic,
.
Sheeting should be removed as soon as is possible once vegetation
is well grown to prevent burning the vegetation through the plastic
sheeting, which acts as a greenhouse.

TERRACE DRAIN
Figure 3 - Cross section of slope drain
I 6. "Permanent Slope Down Drains": A concrete V-ditch extending from the top to the bottom
of a cut or fill slope to convey concentrated runoff down the face of a cut or fill slope without
causing erosion,
Applicable Conditions: This practice applies to construction areas where stormwater
runoff above a cut or fill slope will cause erosion if allowed to flow over the slope.
Temporary slope drains are generally used in conjunction with terrace drains to convey
runoff down a slope,
Design:
Capacity: Peak runoff from the 10-yr storm,
.
. Outlet protection: Protect the outlet of the slope drain from erosion,
, 7. "Outlet Stabilization": Structurally lined aprons or other acceptable energy dissipating
devices placed at the outlets or pipes or paved channel sections,

Applicable Conditions: Applicable to the outlets of all pipes, interceptor swale outlets, and
channel sections where the velocity of flow at the design capacity of the outlet will exceed
the permissible velocity of the receiving channel or area.
Design:
, fl:\Pdala\l5100118\OFHCh"\WPWIN\118'wppplll.wpt!
.
Capacity: 1 O-yr, peak runoff or the design discharge of the water
conveyance structure, whichever is greater.
.
Tailwaterdepth: Determine the depth oftailwater immediately below
the pipe outlet based on the design discharge plus other contributing
flows, If the tailwater depth is less than half the
diameter of the outlet pipe and the receiving stream is sufficiently
wide to accept the divergence of flow, it is classed as aminimum
tailwater condition, If the tailwater depth is greater than half the
pipe diameter, it is classed as a maximum tailwater condition,
Pipes that outlet onto broad flat areas with no defined channel may
be assumed to have a minimum tailwater condition unless site
conditions indicate otherwise.
.
Apron size: The apron length and width can be determined
according to the tailwater condition, If the water conveyance
structure discharges directly into a well-defined channel, extend the
apron across the channel bottom and up the channel banks to an
elevation of 0,5 ft above the maximum tailwater depth or to the top of
the bank, whichever is less. Determine the maximum allowable
velocity for the receiving stream, and design the rip rap apron to
reduce flow to this velocity before flow leaves the apron. Calculate
the apron length for velocity control or use the length required to
meet stable conditions downstream, whichever is greater.
.
Grade: Ensure that the apron has zero grade, There should be no
overfall at the end of the apron; that is, the elevation of the top of the
rip rap at the downstream end should be the same as the elevation
of the bottom of the receiving channel or the adjacent ground ifthere
is no channel.
.
Alignment: The apron should be straight throughout its entire length,
but if a curve is necessary to align the apron with the receiving
stream, locate the curve in the upstream section of rip rap,
.
Materials: Ensure that rip rap consists of a well-graded mixture of
stone, Larger stone should predominate, with sufficient smaller sizes
to fill the voids between the stones, The diameter of the largest
stone size should be no greater than 1,5 times the d50 size,
.
Thickness: Make the minimum thickness of rip rap 1,5 times the
maximum stone diameter.

. Stone quality: Select stone for rip rap from field stone or quarry
stone, The stone should be hard, angular, and highly weather-
resistant. The specific gravity of the individual stones should be at
least 2,5.
. Filter: Install a filter to prevent soil movement through the openings
in the rip rap, The filter should consist of a graded gravel layer or a
synthetic filter cloth.
18. "Sand Bag Inlet Protection":
Applicable Conditions: Inlet locations that are subject to significant amounts of
sedimentation, Sand bag inlet protection is particularly applicable where the inlet exists in
a graded area, in an unpaved street, or at sump locations,
Design:
.
Inlet shall be completely surrounded by at least a double row of
sandbags, two bags high,
! 9. "Temporary Sediment Trap": A temporary basin with a controlled stormwater release
structure formed by constructing an embankment of compacted soil across a drainage way,
or other suitable locations,
Applicable Conditions: Proposed construction sites where the tributary drainage is less
than 10 acres,
Design:
.
The sediment pond may be formed by partial excavation and/or by
construction of a compacted embankment. It may have one or more
inflow points carrying polluted runoff, Baffles to spread the flow
throughout the basin should be included, A securely anchored riser
pipe is the principal discharge mechanism along with an emergency
overflow spillway, The riser pipe shall be solid with two 1-inch
diameter dewatering holes located at the top of the sediment storage
volume on opposite sides of the riser pipe. Outlet protection is
provided to reduce erosion at the pipe outlet.
The sediment pond volume is the sum of the sediment storage
volume (3 feet in depth) plus a settling volume of not less than 2 feet
in depth, The sediment depth is computed based on the basin
surface area required to settle out the design particle at the design
inflow rate.
.
.
Storage capacity: Keep the minimum volume of the sediment trap at
1800 ft3/acre based on disturbed area draining into the basin,
Measure volume below the crest elevation of the outlet. The volume
of a natural sediment trap may be satisfactorily approximated by the

equation: volume (ft') = 0.4 x surface area (ft2) x maximum pool
depth (ft)
.
Trap c1eanout: Remove sediment from the trap and restore the
capacity to original trap dimensions when sediment has accumulated
to one-half design depth,
.
Embankment: Ensure that embankments for temporary sediment
traps do not exceed 5 ft in height measured at the center line from
the original ground surface to the top of the embankment. Additional
freeboard may be added to the embankment height to allow flow
through a designated bypass location, Construct embankments with
a minimum top width of 5 ft and side slopes of 2: 1 or flatter, Machine
compact embankments,
.
Excavation: Where sediment pools are formed or enlarged by
excavation, keep side slopes at 2:1 or flatter for safety,
.
Outlet section: Construct the sediment trap outlet using a stone
section of embankment located at the low point in the basin. The
stone section serves two purposes: (1) the top section serves as a
nonerosive spillway outlet for flood flows, and (2) the bottom section
provides a means of dewatering the basin between runoff events,
.
Stone size: Construct the outlet using well-graded stones with a dso
size of 9 inches (class B erosion control stone is recommended) and
a maximum stone size of 14 inches, A 1-ft thick layer of Yz - 'Jr.-inch
aggregate washed stone is recommended and should be placed on
the inside face to reduce drainage flow rate,
.
Side slopes: Keep the side slopes of the spillway section at 2:1 or
flatter, To protect the embankment, keep the sides of the spillway at
least 21 inches thick,
.
Depth: Keep the crest of the spillway outlet a minimum of 1,5 ft
below the settled top of the embankment.
.
Protection from piping: Place filter cloth on the foundation below the
rip rap to prevent piping. An alternative would be to excavate a
keyway trench across the rip rap foundation and up the sides to the
height of the dam.
.
Weir length and depth: Keep the spillway weir at least 4 ft long and
sized to pass the peak discharge of the 10-yr storm. A maximum
flow depth of 1 ft, a minimum freeboard of 0,5 ft, and maximum side
slopes of 2: 1 are recommended.

Applicable Conditions: Soil-water interfaces, where the soil conditions, water turbulence,
water velocity, and expected vegetative cover, are such that the soil may erode under the
design flow conditions,
Design:
Stone should be hard, angular, and highly weather resistant, and not
flat or elongated, The specific gravity of individual stones should be
at least 2,5,
.
.
The minimum thickness of rip-rap shall be 1.5 times the maximum
stone diameter.
.
Sizing of the stone and rip-rap basin shall be based upon the
incoming velocity of the water.

POST-CONSTRUCTION STORM WATER MANAGEMENT
Following construction ofthe overall project, the existing local onsite storm drain system shall collect
, and convey onsite generated runoff and connect to the storm drain system as previously discussed
in Section 3 under "Site Drainage Patterns", The following control practices are intended to reduce
, pollutants in the project's storm water discharge after all construction phases have been completed
,at the site, These are consistent with all local post construction storm water management
requirements, policies, and guidelines, Site-specific and seasonal conditions must be considered
, when designing the control practices.
, Control Measures
'The focus of the development of a post-construction storm water management for this project relies
,on the implementation of "source control" Best Management Practices (BMP's) rather than
'treatment of stormwater pollution. The main objective or philosophy is to ensure that the pollution
, does not come in contact with stormwater or avoid creating the problem in the first place, Source
, control emphasizes the prevention and reduction of nonpoint pollution by eliminating the opportunity
for pollutants on the land surface to enter surface runoff,
, Structural Control Measures
'The only structural controls required are permanent vegetative controls on landscaped and
, uncovered areas and permanent terrace and down drains on slopes greater than 30 feet in height.
