STANDARD EROSION AND SEDIMENT CONTROL NOTES
1) The City Stormwater Department erosion control inspector must be notified at least 24 hours
prior to any construction on this site.
2) All required BMPs shall be installed prior to any land disturbing activity (e.g., stockpiling,
stripping, grading, etc). All of required erosion control measures must be installed at the
appropriate time in the construction sequence as indicated in the approved project schedule,
construction plans, and erosion control report.
3) Pre-disturbance vegetation shall be protected and retained wherever possible. Removal or
disturbance of existing vegetation shall be limited to the area required for immediate
construction operations, and for the shortest practical period of time.
4) All soils exposed during land disturbing activity (stripping, grading, utility installations,
stockpiling, filling, etc.) shall be kept in a roughened condition by ripping or disking along land
contours until mulch, vegetation or other permanent erosion control is installed. No soils in
areas outside project street rights-of-way shall remain exposed by land disturbing activity for
more than thirty-(30) days before required temporary or permanent erosion control (e.g.
seed/mulch, landscaping, etc.) is installed, unless otherwise approved by the Stormwater
Department.
5) The property must be watered and maintained at all times during construction activities so
as to prevent wind-caused erosion. All land disturbing activities shall be immediately
discontinued when fugitive dust impacts adjacent properties, as determined by the City
Engineering Department.
6) All temporary (structural) erosion control measures must be inspected and repaired or
reconstructed as necessary after each runoff event and every 14 days in order to assure
continued performance of their intended function. All retained sediments, particularly those on
paved roadway surfaces, shall be removed and disposed of in a manner and location so as not
to cause their release into any drainage way.
7) No soil stockpile shall exceed ten-(10) feet in height. All soil stockpiles shall be protected
from sediment transport by surface roughening, watering and perimeter silt fencing. Any soil
stockpile remaining after 30 days shall be seeded and mulched.
8) City Ordinance prohibits the tracking, dropping or depositing of soils or any other material
onto city streets by or from any vehicle. Any inadvertent deposited material shall be cleaned
immediately by the contractor.
9) Additional notes can (should) be added to reflect the erosion/sediment control plan of the
individual development.

SECTION 1 SITE DESCRIPTION
i. Site Location
The overall Bloom development is bordered to the north by East Vine Drive; to the east by
the Imu-Tek Animal Health Clinic and undeveloped land; to the south by East Mulberry
Street; and to the west by East Ridge Second Filing, also referred to as the Mosaic
Subdivision. The project site is located in the Northwest Quarter of Section 9, Township 7
N., Range 66 W. of the 6th P.M., City of Fort Collins, County of Larimer, State of Colorado.
A vicinity map is included in Appendix A for reference.
Project Coordinate Location:
· Longitude 105°01'0.61"W
· Latitude 40°35'17.9"N
CDPS Permit #:To Be Determined
*A copy of the permit is available in Appendix F
ii. Description of Adjacent Areas
The project site consists of approximately 260 acres of vacant and undeveloped tract of land
that is currently being used for farming. Existing grades across the site vary from 0.5 to 3
percent. The site generally drains from north to south. There are existing train tracks across
the northern portion of the site that run diagonal from the northwest to the southeast. The
project site is located within the Cooper Slough/Boxelder Basin and the Cooper Slough
channel is located just to the east of the project site. The Lake Canal also cuts across the
southwest corner of the site.
A. NATURE AND PURPOSE OF CONSTRUCTION ACTIVITY
The purpose of this construction activity is to prepare the site for single and multi-family residential
housing construction. Construction activity common to this type of development include: grubbing,
rough grading, installing underground utility mains and service extensions, constructing internal
roadways and establishing finished grade across the site.
B. CONSTRUCTION SEQUENCE OF MAJOR ACTIVITIES
- Estimated project start date: August 2022
- Estimated project completion date:To Be Determined
Major Phases of Construction:
* Refer to Appendix D for the Construction Sequence Matrix.
* Refer to Appendix H for a copy of the Phasing Plan sheets.
- Install initial erosion and sediment controls, such as silt fence and vehicle tracking
control prior to any earth disturbing activity.
- Overlot grade the site. This will include grading the stormwater quality features and
detention ponds. Future phases of the development will be seeded and mulched.
- Install utilities (e.g., domestic water, sanitary sewer and storm sewer)
- Construct Phase I internal roadways.
- Additional erosion and sediment control measures will be installed as the underground
storm drain system is constructed. For example, Inlet Protection (IP) will be placed at
newly constructed Type ‘R’ curb inlets.
- Erosion and sediment control measures will remain in place until final stabilization has
been achieved. The contractor will prepare a detailed construction sequence, including
BMP installation timing, for inclusion in the SWMP.
Final stabilization is anticipated to be performed by the installation of landscaping materials and
seeding where required by the landscape plans. Refer to Appendix H and sheet LS103.
C. AREA OF DISTURBANCE
The total area of the site within the project boundaries is ±260 acres. The overlot grading, utility
installation and roadway construction will account for approximately 66.8 acres of land
disturbance within the project.
Earthwork estimates:
- Cut of 455,818 cubic yards
- Fill of 255,979 cubic yards
- Net Fill of 102,161 cubic yards
D. TOPOGRAPHY, SOILS AND RAINFALL DATA
Existing grades across the site vary from 0.5 to 3 percent. The site generally drains from north
to south.
According to the Natural Resources Conservation (NRCS) Web Soil Survey, the project site
consists of a mix of soil types and Hydrologic Soil Groups (HSG) including:
-Ascalon Sandy Loam (33%), HSG ‘B’
-Fort Collins Loam (27%), HSG ‘C’
-Garrett Loam (23%), HSG ‘B’.
This soil is associated with Hydrologic Soil Group (HSG) ‘C’. HSG ‘C’ soils have a slow
infiltration rate when thoroughly wet and consist chiefly of soils having a layer that impedes the
downward movement of water or soils of moderately fine texture or fine texture. These soils
have a slow rate of water transmission. The remainder of the site consists of a mix of HSG ‘B’
and ‘C’ soils.

Impervious and Runoff Coefficients
Percentage impervious area before construction:0%
Runoff coefficient before construction (C2):0.20
Percentage impervious area after construction (grading):65%
Runoff coefficient after construction (C2):0.70
E. EXISTING VEGETATION
The site was used for agriculture. The ground cover across the existing site consists of native
grasses and weeds. The existing percent vegetation cover very good, ±75%.
F. POTENTIAL POLLUTION SOURCES
During construction there is potential for pollution from grading, utility and roadway construction
activities. Most importantly, these are earth disturbing activities. The potential for pollution arises
not just from grading and excavation but also equipment and material staging areas, equipment
refueling and maintenance, equipment washing and the on-site use of paints, solvents and other
chemicals common to this type of construction activity. Pollution can occur when the
aforementioned are exposed to rainfall and/or runoff. The contact can contaminate Stormwater.
Additionally there is a potential for pollution from the concrete washout area, worker’s trash and
portable toilets. Since the location of this potential pollution is dictated by the current
construction activity, they will be shown and updated on the Site Maps by the Contractor.
G. NON-STORMWATER DISCHARGES
All discharges covered by this permit shall be composed entirely of stormwater associated with
construction activity. There are however, several exceptions including uncontaminated springs,
landscape irrigation return flow, construction dewatering and concrete washout. The SWMP
should address the location and description of any anticipated allowable sources of non-
stormwater discharge at the site.
A designated contained Concrete Washout Area (CWA) is located on the Site Map. The
infiltration discharge of concrete wash water will not be allowed on this construction site. To
avoid infiltration of concrete washout wastewater a plastic liner needs to be installed at the CWA
per the detail drawing or a pre-fabricated container needs to be utilized from which all liquids
and solids can be recovered and disposed of at appropriately licensed off-site disposal facilities.
Under the general permit, concrete washout water cannot be discharged to surface waters or to
storm sewer systems without separate permit coverage.
H. RECEIVING WATERS
The developed site will drain to multiple proposed detention ponds. LID stormwater quality
features will be located throughout the site before ultimately draining into the Detention Ponds.
These proposed features include: a bio retention and sand filters. Developed site runoff will
pass through one of the stormwater quality features before it flows into the detention pond. The
detention ponds will also provide water quality as a means of treating the storm water.
There are two ultimate outfalls for the site’s drainage. One on the upper portion of the Cooper
Slough and another at the southern portion of the site along the Peakview development.
I. SITE FEATURES AND SENSITVE AREAS TO BE PROTECTED
There are no sensitive areas identified on the site.
J. OTHER APPLICABLE FEDERAL, STATE OR LOCAL PROGRAMS,
REGULATIONS OR RESTRICTION
No other applicable restrictions apply. We are not aware of endangered species and the site is
not designated as a historical site.

SECTION 3: STORMWATER MANAGEMENT CONTROLS
A. SWMP ADMINISTRATOR AND IMPORTANT CONTACTS
The SWMP Administrator is responsible for developing, implementing, maintaining and revising
the SWMP. The Contractor shall designate a SWMP Administrator which will be the contact for
all SWMP related issues and the person responsible for its accuracy, completeness and
implementation. The SWMP Administrator should be a person with authority to adequately
manage and direct day-to-day stormwater quality management activities at the site.
The SWMP Administrator is responsible for holding a weekly storm water meeting attended by
the General Contractor with all contractors and subcontractors involved in earth disturbing
activities to review the requirements of the Permit(s), the SWMP and address any problems that
have arisen in implementing the SWMP or maintaining the BMPs. The Contractor shall maintain
a log of all weekly meetings and document the issues addressed in the meetings.
B. IDENTIFICATION OF POTENTIAL POLLUTANT SOURCES
Potential pollutant sources for this site include:
·Disturbed and Stored Soils: The site will be grubbed and overlot graded prior to major
utility and roadway construction. The overlot grading work will occur across the site (i.e.,
all phases of development). All future phases should then receive temporary seeding
and mulching within 7 days of the last disturbance if no further disturbance is expected
for at least 14 days. Place sediment control BMPs. Additional strategies for minimizing
erosion and sediment control can be found in Stockpile Management (SP).
·Vehicle Tracking of Sediments: There is potential for tracking of soils between the
beginning of the grading process and the final stabilization of the site. Vehicle Tracking
Control (VTC) is to be installed prior to land disturbance activities and sweeping is to
take place as needed. Vehicle access to the exposed and disturbed subgrade will be
limited primarily to roll on/off earthmoving equipment and heavy materials delivery
trucks. The SWMP Administrator is responsible for ensuring that access to exposed
subgrade is limited, both in quantity and in timing relative to the tracking susceptibility of
the soil as it relates to moisture content. The SWMP Administrator must keep the
adjacent parking areas and public rights-of-way free from mud and other tracked debris
from the site.
·Management of Contaminated Soils: We are not aware of contaminated soils that
exist within the limits of the proposed earth disturbing activity. Our knowledge of the pre-
development activities within the site does not suggest that contimainated soils will be
discovered during the construction process.
·Loading and Unloading Operations: All loading and unloading operations of
equipment shall be carried out in areas protected by erosion and sediment controls. It is
recommended that all equipment be cleaned on-site and within protected areas prior to
exiting the site.
·Vehicle and Equipment Maintenance and Fueling: Reference Good Housekeeping
Practices (GH) in Appendix E for additional information about good housekeeping
practices designed to prevent pollution associated with solid, liquid and hazardous
construction-related materials and wastes.
If equipment is to be maintained and stored in an open area this area should not be
within the drip line of trees and not be within 100 feet of a watercourse or wetland.
Runoff should be diverted away from watercourses and wetlands. Maintenance should
be done on impervious areas surrounded with impervious berms. Where this is not
possible, use pads designed to contain the pollutants which may leak or spill during
maintenance operations. Impervious pads are particularly important on sandy and other
coarse soils where spilled materials can easily infiltrate and possibly leach into the
groundwater. Equipment shall be checked before and after each use and, at a minimum,
during the weekly stormwater inspection if otherwise idle. Periodic checks of the
equipment wash areas shall be performed to ensure proper operation.
Temporary on-site fuel tanks for construction vehicles shall meet all state and federal
regulations. Tanks shall have approved spill containment with the capacity required by
the applicable regulations. From NFPA 30: All tanks shall be provided with secondary
containment (i.e., containment external to and separate from primary containment).
Secondary containment shall be constructed of materials of sufficient thickness, density
and composition so as not to be structurally weakened as a result of contact with the fuel
stored and capable of containing discharged fuel for a period of time equal to or longer
than the maximum anticipated time sufficient to allow recovery of discharged fuel. It shall
be capable of containing 110% of the volume of the primary tank if a single tank is used,
or in the case of multiple tanks, 150% of the largest tank or 10% of the aggregate,
whichever is larger.
The tanks shall be in sound condition free of rust or other damage which might
compromise containment. Fuel storage areas will meet all EPA, OSHA and other
regulatory requirements for signage, fire extinguisher, etc. Hoses, valves, fittings, caps,
filler nozzles and associated hardware shall be maintained in proper working condition at
all times. The location of fuel tanks shall be shown on the Site Maps and shall be located
to minimize exposure to weather and surface water drainage features.
A Spill Prevention, Control and Countermeasure (SPCC) Plan must be developed if
aboveground oil storage capacity at the construction site exceeds 1,320-gallons or as
specified by state. Containers with a storage capacity of 55-gallons or less are not
included when calculating site storage capacity. The General Contractor shall develop
and implement a SPCC Plan in accordance with the Oil Pollution Prevention regulation
at Title 40 of the Code of Federal Regulations, Part 112, (40 CFR 112).
·Concrete Truck/Equipment Washing: A Concrete Washout Area (CWA) shall be
installed prior to any concrete placement on-site. Signs shall be placed at the
construction entrance(s), at the washout area and elsewhere as necessary to clearly
indicate the location of the concrete washout area. The washout area shall be repaired
and enlarged or cleaned out as necessary to maintain capacity for wasted concrete.
Concrete and concrete wash water shall be removed from the site and disposed of at an
accepted waste facility.
·Non-Industrial Waste Sources:
Portable toilets: All personnel involved with construction activities must comply with state
and local sanitary or septic system regulations. Temporary sanitary facilities will be
provided at the site throughout the construction phase. They must be utilized by all
construction personnel and must be serviced weekly by a commercial operator. The
location of sanitary facilities shall be shown on the Site Maps. Portable toilets must be
securely anchored a minimum of 10’ behind curbs, and are not allowed within 50’ of
inlets or within 50’ of a water of the State or the municipal storm drain system.
Worker’s trash: The site shall be policed at the end of each work day to be kept free of
trash and debris resulting from workers day-to-day activities. If necessary, place clearly
marked and protected containers for trash and debris at convenient locations throughout
the site. The burying of waste on-site is prohibited. Trash must be properly contained at
the end of each day.
·Dedicated Asphalt and Concrete Batch Plants:Neither a dedicated asphalt or
concrete batch plant is anticipated with the proposed construction activity.
C. BMPs FOR STORMWATER POLLUTION PREVENTION
The initial erosion and sediment control measures will consist of installing Silt Fence (SF) along
the perimeter of the site and around the perimeter of anticipated stock pile areas. Vehicle
Tracking Control (VTC) should be installed as shown on C11.0. Prior to construction of any
concrete fixtures a Concrete Washout Area (CWA) shall be installed on site as shown on the
C11.0. After each proposed curb or area inlet is constructed, proper inlet protection will be
installed to minimize sediment and debris discharge. These BMPs will remain in place and be
properly maintained until landscaping is installed and/or final stabilization within the respective
tributary area of the site occurs. All portions of land which may be disturbed will be temporarily
or permanently seeded, landscaped or paved as noted on the design drawings (refer to
Appendix H). The specifics for each measure to be utilized and/or installed are indicated below:
STRUCTURAL PRACTICES
* Refer to Appendix D for details
·Temporary and Permanent Seeding (TS/PS):All denuded areas that will be inactive
for 14 days or more must be stabilized temporarily with the use of fast-germinating
annual grass/grain varieties appropriate for site soil and climate conditions, straw/hay
mulch, wood cellulose fibers, tackifiers, netting and/or blankets. Stockpiles and diversion
ditches/berms must be stabilized to prevent sediment and erosion and dust issues,
respectively.
·Permanent Seeding, Sodding or Mulching (TS/PS): All areas at final grade must be
seeded or sodded within 14 days after completion of work in that area. Prepare soil and
seed immediately after final grade is achieved. On completion of earth disturbing
activities the entire site must have permanent vegetative cover meeting vegetative
density requirements or mulch per landscape plan in all areas not covered by hardscape
(e.g., pavement, buildings, etc.). Except for small (<100 sq.ft.) level spots, seeded areas
should be protected with mulch, tackifier or a rolled erosion control product. Mulch must
be crimped by disc or other machinery.
·Silt Fence (SF):Silt fence is a synthetic permeable woven or non-woven geotextile
fabric incorporating support stakes at intervals sufficient to support the fence (5-feet
maximum distance between posts), water and sediment retained by the fence. The
fence is designed to retain sediment-laden storm water and allow settlement of
suspended soils before the storm water flows through the fabric. Silt fence shall be
located on the contour to capture overland, low-velocity sheet flows.
· Vehicle Tracking Control (VTC):All points closed to the general public and providing
access into the construction site shall include a marked construction exit that will be
monitored for any signs of tracking from the construction site. It is expected that only
trailer delivered equipment will access the exposed subgrades and that vehicle tracking
adjacent to publically accessible parking and public rights-of-way should not be evident.
It may also be necessary to install a wheel wash system. If this is done, a Sediment Trap
(ST) control must be installed to treat the wash water before it discharges from the site.
Discharge must be directed to the detention pond within the limits of construction as
indicated.
·Inlet Protection (IP): Inlet protection should be installed at storm sewer inlets that are
operable during construction. It consists of permeable barriers installed around an inlet
to filter runoff and remove sediment prior to entering the storm drain inlet. The primary
mechanism is to place controls in the path of flow sufficient to slow the sediment-laden
water to allow settlement of suspended soils before discharging into the storm sewer. It
is possible that as construction progresses from storm sewer installation through to
paving that the inlet protection devices should change. All inlet protection devices create
ponding of storm water. This should be taken into consideration when deciding on which
device or devices should be used.
·Straw Wattles (SW)or Sediment Control Logs (SCL): Straw wattles or sediment
control logs consist of straw, compost, excelsior or coconut fiber that are staked to the
ground and designed to prevent sediment transfer. The wattles are designed to retain
sediment-laden storm water and allow settlement of suspended soils before the storm
water flows through the wattle. Straw wattles shall be located on the contour to capture
overland, low-velocity sheet flows.
·Soil Stockpile Management (SP):Soil stockpiles should be located away from all
drainage system components including storm sewer inlets. Sediment control BMPs
should be placed around the perimeter of all stockpiles. Soils stockpiled for more than 30
days should be seeded and mulched with a temporary grass cover.
·Good Housekeeping Practices (GH): Good housekeeping practices include providing
waste management, establishing proper building material staging areas, designating
paint and concrete washout areas, establishing proper equipment and vehicle fueling
and maintenance practices, controlling equipment and vehicle washing and allowable
non-storm water discharges and developing a spill prevention and response plan.
·Stabilized Staging Area:This is a clearly designated area where construction
equipment and vehicles, stockpiles, waste bins and other construction-related materials
are stored. The stabilized storage area consists of a stabilized surface, covered with 3-
inch diameter aggregate or larger.
·Surface Roughening (SR):Surface roughening consists of tracking, scarifying,
imprinting or tilling a disturbed area to provide temporary stabilization of disturbed areas.
It is used to provide temporary stabilization of disturbed areas, such as when re-
vegetation cannot be immediately established.
D. PHASE CONSTRUCTION ACTIVITY AND BMP IMPLEMENTATION
Should there be changes to the implemented BMPs, the Administrator shall be notified and the
SWMP must be modified to accurately reflect the field conditions. Examples include, but are not
limited to, removal of BMPs, identification of new potential pollutant sources, addition of BMPs,
modification of BMP installation and implementation criteria or maintenance procedures and
changes in items included in the Site Map and/or description. SWMP revisions must be made
prior to changes in site conditions, except for Responsive SWMP Changes, as follows:
· SWMP revisions must be made immediately after changes are made in the field to
address BMP installation and/or implementation issues; or
· SWMP revisions that require the development of supporting documentation (e.g., design
of retention pond capacity) must be made as soon as practicable, but in no case more
than 72 hours, after change(s) in BMP installation and/or implementation occur at the
site.
This SWMP should be viewed as a “living document” that is to be continuously reviewed and
modified as part of the overall process of assessing and managing storm water quality issues
on-site.
E. HAZARDOUS MATERIAL HANDLING AND SPILL PREVENTION
Any hazardous or potentially hazardous material that is brought onto the construction site will be
handled properly in order to reduce the potential for storm water pollution. All materials used on
this construction site will be properly stored including the use of secondary containment
measures, handled, dispensed and disposed of following all applicable label directions.
Flammable and combustible liquids will be stored and handled according to 29 CFR 1926.152.
Only approved containers and portable tanks shall be used for storage and handling of
flammable and combustible liquids.
Material Safety Data Sheets (MSDS) information will be kept on-site for any and all applicable
materials.
In the event of an accidental spill, immediate action will be undertaken by the General
Contractor to contain and remove the spilled material. All hazardous materials will be disposed
of by the Contractor in the manner specified by federal, state and local regulations and by the
manufacturer of such products. As soon as possible, the spill will be reported to the appropriate
agencies. As required under the provisions of the Clean Water Act, any spill or discharge
entering waters of the United States will be properly reported. The General Contractor will
prepare a written record of all spills and-+ associated clean-up and will provide also notify the
City of Fort Collins (970-221-6700) and the Colorado Department of Public Health and
Environment (CDPHE) (1-877-518-5608). The General Contractor will provide notice to Owner
immediately upon identification of a reportable spill.
Any spills of petroleum products or hazardous materials in excess of Reportable Quantities as
defined by EPA or the state or local agency regulations, shall be immediately reported to the
EPA National Response Center (1-800-424-8802), the Colorado Department of Public Health
and Environment (CDPHE) (1-877-518-5608) and the City of Fort Collins (970-221-6700).
The State reportable quantity for petroleum products is 25 gallons or more (or that cause sheen
on nearby surface waters). Spills from regulated aboveground and underground fuel storage
tanks must be reported to the State Oil Inspector within 24 hours (after-hours contact CDPHE
Emergency Spill Reporting Line). This includes spills from fuel pumps. Spills or releases of
hazardous substances from regulated storage tanks in excess of the reportable quantity (40
CFR Part 302.6) must be reported to the National Response Center, the local fire authority
immediately, the State Oil Inspector and the City of Fort Collins within 24 hours.
In order to minimize the potential for a spill of petroleum products or hazardous materials to
come in contact with storm water, the following steps will be implemented:
a) All materials with hazardous properties (such as pesticides, petroleum products,
fertilizers, detergents, construction chemicals, acids, paints, paint solvents, additives
for soil stabilization, concrete, curing compounds and additives, etc.) will be stored,
including secondary containment measures in a secure location and under cover,
when not in use.
b) The minimum practical quantity of all such materials will be kept on the job site
and scheduled for delivery as close to the time of use as practical.
c) A spill control and containment kit (containing for example, absorbent material
such as kitty litter or sawdust, acid neutralizing agent, brooms, dust pans, mops,
rags, gloves, goggles, plastic and metal trash containers, etc.) will be provided on the
construction site and location(s) shown on Site Maps. The kit should be inspected for
completeness as a part of weekly storm water inspections.
d) All of the product in a container will be used before the container is disposed of.
All such containers will be triple rinsed, with water, prior to disposal. The rinse water
used in these containers will be disposed of in a manner in compliance with State
and federal regulations and will not be allowed to mix with stormwater discharges.
e) All products will be stored in and used from the original container with the original
product label.
f) All products will be used in strict compliance with instructions on the product
label.
g) The disposal of excess or used products will be in strict compliance with
instructions on the products label and local regulations.
The contractor is responsible for the Spill Prevention and Control Plan (SPCP). If the contractor
elects to provide his own SPCP, it must be included in the Appendix as a replacement. A
contractor provided SPCP shall clearly state measures to stop the source of a spill, contain the
spill, clean up the spill, dispose of contaminated materials and train personnel to prevent and
control future spills. In addition the SPCP must include contact and documentation requirements
for each of the Minor, Significant and Hazardous spill magnitudes. Further requirements are
listed below in the equipment fueling section.
SECTION 4: FINAL STABILIZATION & LONG-TERM STORMWATER
MANAGEMENT
a) In accordance with Part 1.C.4.c of the CDPS General Permit for Stormwater Discharges
Associated with Construction Activity (COR-300000) (the stormwater permit):
“Final stabilization is reached when all ground surface disturbing activities at the
site have been completed and uniform vegetative cover has been established
with an individual plant density of at least 70 percent of pre-disturbance levels, or
equivalent permanent, physical erosion reduction methods have been
employed.”
The following criteria must be met when planning for final stabilization:
· Stabilization must be permanent
· ALL disturbed areas must be stabilized
· Alternatives must follow good practice
The stormwater permit allows the use of alternatives to vegetation to achieve final
stabilization. These alternatives must meet specific criteria to be considered equivalent
to vegetation. Examples of alternative stabilization practices include:
· Permanent Paving and Buildings
· Hardscape
· Geogrid
· Xeriscape
· Compacted and Stabilized Unpaved Driving Surfaces
The areas of the site that are associated with future filings of development and remain
exposed by land disturbing activity for more than thirty-(30) days, will require temporary
or permanent erosion control (e.g. seed/mulch, landscaping, etc.) to be installed, unless
otherwise approved by the Stormwater Department.
As the lots and blocks achieve final stabilization (see above), the BMPs associated with
them can be removed.

SECTION 5: INSPECTION & MAINTENANCE
The contractor must keep the approved SWMP on-site at all times. An individual certified to
inspect erosion and sediment control by a recognized organization must conduct all BMP
inspections. Proof of certification shall be included in the SWMP. All regulatory authorities may
inspect the land or site covered by the SWMP at any time, without prior notice, for compliance
with the SWMP. If site conditions indicate that the objectives of this section are not being met,
the operator shall make appropriate modifications to the SWMP. Any modification must be
recorded on the owner’s copy of the SWMP and the Administrator notified. The contractor must
maintain inspection records on-site with the SWMP and such records must be provided to the
regulatory agencies for review upon request. The contractor must notify the Administrator if
there is a change in design, construction, operation or maintenance that has a significant effect
on the potential for discharge of pollutants to the MS4 or receiving waters and the SWMP must
be amended. The contractor must notify the Administrator and the SWMP amended, if the
SWMP proves to be ineffective in achieving the general objectives of controlling pollutants in
stormwater discharges associated with construction activities.
INSPECTION PROCEDURES
Between the time this SWMP is implemented and final Inactivation Notice has been submitted,
thorough inspections will occur at least every 14 calendar days. Also, post-storm event
inspections must be conducted within 24 hours after the end of precipitation event or snowmelt
that could potentially cause surface erosion. The purpose of site inspections is to assess
performance of pollutant controls. Based on these inspections the contractor, in consultation
with the Administrator (if different) will decide whether it is necessary to modify this SWMP, add
or relocate controls, or revise or implement additional Best Management Practices (BMPs) in
order to prevent pollutants from leaving the site via storm water runoff. The contractor has the
duty to cause pollutant control measures to be repaired, modified, supplemented or take
additional steps as necessary in order to achieve effective pollutant control.
Note: If a BMP is covered by snow, mark the BMP as not applicable and document the reason
the BMP can not be inspected on the daily report.
Examples of specific items to evaluate during site inspections are listed below. This list is not
intended to be comprehensive. During each inspection, the inspector must evaluate overall
pollutant control system performance as well as particular details of individual system
components. Additional factors should be considered as appropriate to the circumstances.
·Vehicle Tracking Control (VTC):Locations where vehicles enter and exit the site must
be inspected for evidence of off-site sediment tracking. A stabilized construction exit
shall be constructed where vehicles enter and exit. Exits shall be maintained or
supplemented as necessary to prevent the release of sediment from vehicles leaving the
site. Any sediment deposited on the roadway shall be swept as necessary throughout
the day or at the end of every day and disposed of in an appropriate manner. Sediment
shall NOT be washed into storm sewer systems.
·Erosion Control Devices:Rolled Erosion Control Products (i.e., nets, blankets, turf
reinforcement mats) and marginally vegetated areas (i.e., areas not meeting required
vegetative densities for final stabilization) must be inspected weekly. Rills, gullies, ruts
and other signs of erosion indicate the erosion control device is not functioning properly.
Repair and/or additional erosion control devices may be warranted.
·Material Storage Areas:Material storage areas should be located to minimize exposure
to weather and runoff. Inspections shall evaluate disturbed areas and areas used for
storing materials that are exposed to rainfall for evidence of, or the potential for,
pollutants entering the drainage system or discharging from the site. If necessary, the
materials must be covered or original covers must be repaired or supplemented. Also,
protective berms must be constructed, if needed, in order to contain runoff from material
storage areas. All state and local regulations pertaining to material storage areas will be
adhered to.
·Discharge Points:All discharge points must be inspected to determine whether erosion
and sediment control measures are effective in preventing discharge of sediment from
the site or impacts to receiving waters.
BMP MAINTENANCE
The Stormwater Construction Permit requires that all erosion and sediment control practices
and other protective measures identified in the SWMP be maintained in effective operating
condition, and in accordance with good engineering, hydrologic and pollution control practices.
Sediment that has been collected by sediment controls, such as silt fence and inlet protection,
shall be removed when observed, to prevent failure of BMPs, ensure adequate BMP
performance and remove the potential of that sediment from being discharged from the site if
the BMP did fail. Removed sediment shall be properly disposed of on-site. Maintenance
activities to correct problems noted during inspections must be documented as discussed in the
documentation section, below. The inspection process must also include procedures to ensure
that, when needed, BMPs are replaced or new BMPs added to adequately manage the pollutant
sources at the site. This procedure is part of the ongoing process of revising the BMPs and the
SWMP as discussed above, and any changes to BMPs must be recorded in the SWMP. The
SWMP must be modified as soon as practicable to reflect current conditions. BMPs that have
failed, or have the potential to fail without maintenance or modifications, must be addressed as
soon as possible, immediately in most cases, to prevent the discharge of pollutants.
DOCUMENTATION
All erosion control measures and stabilizations shall be inspected at least once every 14
calendar days. Also, post-storm event inspections must be conducted within 24 hours after the
end of precipitation event or snowmelt that could potentially cause surface erosion. The
permittee must document inspection results and maintain a record of the results for a period of
three-(3) years following closing of permit coverage. Sample inspection logs are included in
Appendix G. These records must be made available to the Owner, the City & County, the State
or the EPA upon request. The following items must be documented as part of the site
inspections:
· The inspection date
· Name(s) and title(s) of personnel making the inspection
· Location(s) of discharges of sediment or other pollutants from the site
· Location(s) of BMPs that need to be maintained
· Location(s) of BMPs that failed to operate as designed or proved inadequate for a
particular location
· Location(s) where additional BMPs are needed that were not in place at the time of
inspection
· Deviations from the minimum inspection schedule as indicated above
· Description and dates of corrective actions taken including requisite changes to the
SWMP.
A complete copy of the SWMP shall be kept with the inspection and maintenance records for
the aforementioned three-(3) year period.

Description
Hydrologic soil groups are based on estimates of runoff potential. Soils are
assigned to one of four groups according to the rate of water infiltration when the
soils are not protected by vegetation, are thoroughly wet, and receive
precipitation from long-duration storms.
The soils in the United States are assigned to four groups (A, B, C, and D) and
three dual classes (A/D, B/D, and C/D). The groups are defined as follows:
Group A. Soils having a high infiltration rate (low runoff potential) when
thoroughly wet. These consist mainly of deep, well drained to excessively
drained sands or gravelly sands. These soils have a high rate of water
transmission.
Group B. Soils having a moderate infiltration rate when thoroughly wet. These
consist chiefly of moderately deep or deep, moderately well drained or well
drained soils that have moderately fine texture to moderately coarse texture.
These soils have a moderate rate of water transmission.
Group C. Soils having a slow infiltration rate when thoroughly wet. These consist
chiefly of soils having a layer that impedes the downward movement of water or
soils of moderately fine texture or fine texture. These soils have a slow rate of
water transmission.
Group D. Soils having a very slow infiltration rate (high runoff potential) when
thoroughly wet. These consist chiefly of clays that have a high shrink-swell
potential, soils that have a high water table, soils that have a claypan or clay
layer at or near the surface, and soils that are shallow over nearly impervious
material. These soils have a very slow rate of water transmission.
If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is
for drained areas and the second is for undrained areas. Only the soils that in
their natural condition are in group D are assigned to dual classes.

Silt Fence (SF) SC-1
November 2010 Urban Drainage and Flood Control District SF-1
Urban Storm Drainage Criteria Manual Volume 3
Photograph SF-1. Silt fence creates a sediment barrier, forcing
sheet flow runoff to evaporate or infiltrate.
Description
A silt fence is a woven geotextile fabric
attached to wooden posts and trenched
into the ground. It is designed as a
sediment barrier to intercept sheet flow
runoff from disturbed areas.
Appropriate Uses
A silt fence can be used where runoff is
conveyed from a disturbed area as sheet
flow. Silt fence is not designed to
receive concentrated flow or to be used
as a filter fabric. Typical uses include:
Down slope of a disturbed area to
accept sheet flow.
Along the perimeter of a receiving
water such as a stream, pond or
wetland.
At the perimeter of a construction site.
Design and Installation
Silt fence should be installed along the contour of slopes so that it intercepts sheet flow. The maximum
recommended tributary drainage area per 100 lineal feet of silt fence, installed along the contour, is
approximately 0.25 acres with a disturbed slope length of up to 150 feet and a tributary slope gradient no
steeper than 3:1. Longer and steeper slopes require additional measures. This recommendation only
applies to silt fence installed along the contour. Silt fence installed for other uses, such as perimeter
control, should be installed in a way that will not produce concentrated flows. For example, a "J-hook"
installation may be appropriate to force runoff to pond and evaporate or infiltrate in multiple areas rather
than concentrate and cause erosive conditions parallel to the silt fence.
See Detail SF-1 for proper silt fence installation, which involves proper trenching, staking, securing the
fabric to the stakes, and backfilling the silt fence. Properly installed silt fence should not be easily pulled
out by hand and there should be no gaps between the ground and the fabric.
Silt fence must meet the minimum allowable strength requirements, depth of installation requirement, and
other specifications in the design details. Improper installation
of silt fence is a common reason for silt fence failure; however,
when properly installed and used for the appropriate purposes, it
can be highly effective.

Maintenance and Removal
Inspection of silt fence includes observing the
material for tears or holes and checking for slumping
fence and undercut areas bypassing flows. Repair of
silt fence typically involves replacing the damaged
section with a new section. Sediment accumulated
behind silt fence should be removed, as needed to
maintain BMP effectiveness, typically before it
reaches a depth of 6 inches.
Silt fence may be removed when the upstream area
has reached final stabilization.

Urban Storm Drainage Criteria Manual Volume 3
Photographs SCL-1 and SCL-2. Sediment control logs used as 1) a
perimeter control around a soil stockpile; and, 2) as a "J-hook"
perimeter control at the corner of a construction site.
Description
A sediment control log is a linear roll
made of natural materials such as
straw, coconut fiber, or compost. The
most common type of sediment control
log has straw filling and is often
referred to as a "straw wattle." All
sediment control logs are used as a
sediment barrier to intercept sheet flow
runoff from disturbed areas.
Appropriate Uses
Sediment control logs can be used in
the following applications to trap
sediment:
As perimeter control for stockpiles
and the site.
As part of inlet protection designs.
As check dams in small drainage
ditches. (Sediment control logs
are not intended for use in
channels with high flow
velocities.)
On disturbed slopes to shorten flow
lengths (as an erosion control).
As part of multi-layered perimeter control along a receiving water such as a stream, pond or wetland.
Sediment control logs work well in combination with other layers of erosion and sediment controls.
Design and Installation
Sediment control logs should be installed along the contour to avoid concentrating flows. The maximum
allowable tributary drainage area per 100 lineal feet of sediment control log, installed along the contour, is
approximately 0.25 acres with a disturbed slope length of up to 150 feet and a tributary slope gradient no
steeper than 3:1. Longer and steeper slopes require additional measures. This recommendation only
applies to sediment control logs installed along the contour. When installed for other uses, such as
perimeter control, it should be installed in a way that will not
produce concentrated flows. For example, a "J-hook"
installation may be appropriate to force runoff to pond and
evaporate or infiltrate in multiple areas rather than concentrate
and cause erosive conditions parallel to the BMP.

Urban Storm Drainage Criteria Manual Volume 3
Although sediment control logs initially allow runoff to flow through the BMP, they can quickly become
a barrier and should be installed as if they are impermeable.
Design details and notes for sediment control logs are provided in the following details. Sediment logs
must be properly installed per the detail to prevent undercutting, bypassing and displacement. When
installed on slopes, sediment control logs should be installed along the contours (i.e., perpendicular to
flow).
Improper installation can lead to poor performance. Be sure that sediment control logs are properly
trenched (if lighter than 8 lb/foot), anchored and tightly jointed.
Maintenance and Removal
Be aware that sediment control logs will eventually degrade. Remove accumulated sediment before the
depth is one-half the height of the sediment log and repair damage to the sediment log, typically by
replacing the damaged section.
Once the upstream area is stabilized, remove and properly dispose of the logs. Areas disturbed beneath
the logs may need to be seeded and mulched. Sediment control logs that are biodegradable may
occasionally be left in place (e.g., when logs are used in conjunction with erosion control blankets as
permanent slope breaks). However, removal of sediment control logs after final stabilization is typically
appropriate when used in perimeter control, inlet protection and check dam applications. Compost from
compost sediment control logs may be spread over the area and seeded as long as this does not cover
newly established vegetation.

Urban Storm Drainage Criteria Manual Volume 3
Photograph VTC-1. A vehicle tracking control pad constructed with
properly sized rock reduces off-site sediment tracking.
Description
Vehicle tracking controls provide
stabilized construction site access where
vehicles exit the site onto paved public
roads. An effective vehicle tracking
control helps remove sediment (mud or
dirt) from vehicles, reducing tracking onto
the paved surface.
Appropriate Uses
Implement a stabilized construction
entrance or vehicle tracking control where
frequent heavy vehicle traffic exits the
construction site onto a paved roadway. An
effective vehicle tracking control is
particularly important during the following conditions:
Wet weather periods when mud is easily tracked off site.
During dry weather periods where dust is a concern.
When poorly drained, clayey soils are present on site.
Although wheel washes are not required in designs of vehicle tracking controls, they may be needed at
particularly muddy sites.
Design and Installation
Construct the vehicle tracking control on a level surface. Where feasible, grade the tracking control
towards the construction site to reduce off-site runoff. Place signage, as needed, to direct construction
vehicles to the designated exit through the vehicle tracking control. There are several different types of
stabilized construction entrances including:
VTC-1. Aggregate Vehicle Tracking Control. This is a coarse-aggregate surfaced pad underlain by a
geotextile. This is the most common vehicle tracking control, and when properly maintained can be
effective at removing sediment from vehicle tires.
VTC-2. Vehicle Tracking Control with Construction Mat or Turf Reinforcement Mat. This type of
control may be appropriate for site access at very small construction sites with low traffic volume over
vegetated areas. Although this application does not typically remove sediment from vehicles, it helps
protect existing vegetation and provides a stabilized entrance.

VTC-3. Stabilized Construction Entrance/Exit with Wheel Wash. This is an aggregate pad, similar
to VTC-1, but includes equipment for tire washing. The wheel wash equipment may be as simple as
hand-held power washing equipment to more advance proprietary systems. When a wheel wash is
provided, it is important to direct wash water to a sediment trap prior to discharge from the site.
Vehicle tracking controls are sometimes installed in combination with a sediment trap to treat runoff.
Maintenance and Removal
Inspect the area for degradation and
replace aggregate or material used for a
stabilized entrance/exit as needed. If the
area becomes clogged and ponds water,
remove and dispose of excess sediment
or replace material with a fresh layer of
aggregate as necessary.
With aggregate vehicle tracking controls,
ensure rock and debris from this area do
not enter the public right-of-way.
Remove sediment that is tracked onto the
public right of way daily or more
frequently as needed. Excess sediment
in the roadway indicates that the
stabilized construction entrance needs
maintenance.
Ensure that drainage ditches at the
entrance/exit area remain clear.
A stabilized entrance should be removed only when there is no longer the potential for vehicle tracking to
occur. This is typically after the site has been stabilized.
When wheel wash equipment is used, be sure that the wash water is discharged to a sediment trap prior to
discharge. Also inspect channels conveying the water from the wash area to the sediment trap and
stabilize areas that may be eroding.
When a construction entrance/exit is removed, excess sediment from the aggregate should be removed
and disposed of appropriately. The entrance should be promptly stabilized with a permanent surface
following removal, typically by paving.

Inlet Protection (IP) SC-6
August 2013 Urban Drainage and Flood Control District IP-1
Urban Storm Drainage Criteria Manual Volume 3
Photograph IP-1. Inlet protection for a curb opening inlet.
Description
Inlet protection consists of permeable
barriers installed around an inlet to
filter runoff and remove sediment prior
to entering a storm drain inlet. Inlet
protection can be constructed from rock
socks, sediment control logs, silt fence,
block and rock socks, or other materials
approved by the local jurisdiction.
Area inlets can also be protected by
over-excavating around the inlet to
form a sediment trap.
Appropriate Uses
Install protection at storm sewer inlets
that are operable during construction.
Consider the potential for tracked-out
sediment or temporary stockpile areas to contribute sediment to inlets when determining which inlets
must be protected. This may include inlets in the general proximity of the construction area, not limited
to downgradient inlets. Inlet protection is not a stand-alone BMP and should be used in conjunction with
other upgradient BMPs.
Design and Installation
To function effectively, inlet protection measures must be installed to ensure that flows do not bypass the
inlet protection and enter the storm drain without treatment. However, designs must also enable the inlet
to function without completely blocking flows into the inlet in a manner that causes localized flooding.
When selecting the type of inlet protection, consider factors such as type of inlet (e.g., curb or area, sump
or on-grade conditions), traffic, anticipated flows, ability to secure the BMP properly, safety and other
site-specific conditions. For example, block and rock socks will be better suited to a curb and gutter
along a roadway, as opposed to silt fence or sediment control logs, which cannot be properly secured in a
curb and gutter setting, but are effective area inlet protection measures.
Several inlet protection designs are provided in the Design Details. Additionally, a variety of proprietary
products are available for inlet protection that may be approved for use by local governments. If
proprietary products are used, design details and installation procedures from the manufacturer must be
followed. Regardless of the type of inlet protection selected, inlet protection is most effective when
combined with other BMPs such as curb socks and check dams. Inlet protection is often the last barrier
before runoff enters the storm sewer or receiving water.

Propriety inlet protection devices should be installed in accordance with manufacturer specifications.
More information is provided below on selecting inlet protection for sump and on-grade locations.
Inlets Located in a Sump
When applying inlet protection in sump conditions, it is important that the inlet continue to function
during larger runoff events. For curb inlets, the maximum height of the protective barrier should be lower
than the top of the curb opening to allow overflow into the inlet during larger storms without excessive
localized flooding. If the inlet protection height is greater than the curb elevation, particularly if the filter
becomes clogged with sediment, runoff will not enter the inlet and may bypass it, possibly causing
localized flooding, public safety issues, and downstream erosion and damage from bypassed flows.
Area inlets located in a sump setting can be protected through the use of silt fence, concrete block and
rock socks (on paved surfaces), sediment control logs/straw wattles embedded in the adjacent soil and
stacked around the area inlet (on pervious surfaces), over-excavation around the inlet, and proprietary
products providing equivalent functions.
Inlets Located on a Slope
For curb and gutter inlets on paved sloping streets, block and rock sock inlet protection is recommended
in conjunction with curb socks in the gutter leading to the inlet. For inlets located along unpaved roads,
also see the Check Dam Fact Sheet.
Maintenance and Removal
Inspect inlet protection frequently. Inspection and maintenance guidance includes:
Inspect for tears that can result in sediment directly entering the inlet, as well as result in the contents
of the BMP (e.g., gravel) washing into the inlet.
Check for improper installation resulting in untreated flows bypassing the BMP and directly entering
the inlet or bypassing to an unprotected downstream inlet. For example, silt fence that has not been
properly trenched around the inlet can result in flows under the silt fence and directly into the inlet.
Look for displaced BMPs that are no longer protecting the inlet. Displacement may occur following
larger storm events that wash away or reposition the inlet protection. Traffic or equipment may also
crush or displace the BMP.
Monitor sediment accumulation upgradient of the inlet protection.
Inlet Protection (IP) SC-6
August 2013 Urban Drainage and Flood Control District IP-3
Urban Storm Drainage Criteria Manual Volume 3
Remove sediment accumulation from the area upstream of the inlet protection, as needed to maintain
BMP effectiveness, typically when it reaches no more than half the storage capacity of the inlet
protection. For silt fence, remove sediment when it accumulates to a depth of no more than 6 inches.
Remove sediment accumulation from the area upstream of the inlet protection as needed to maintain
the functionality of the BMP.
Propriety inlet protection devices should be inspected and maintained in accordance with
manufacturer specifications. If proprietary inlet insert devices are used, sediment should be removed
in a timely manner to prevent devices from breaking and spilling sediment into the storm drain.
Inlet protection must be removed and properly disposed of when the drainage area for the inlet has
reached final stabilization.

Temporary Outlet Protection (TOP) EC-8
November 2010 Urban Drainage and Flood Control District TOP-1
Urban Storm Drainage Criteria Manual Volume 3
Photograph TOP-1. Riprap outlet protection.
Description
Outlet protection helps to reduce erosion
immediately downstream of a pipe,
culvert, slope drain, rundown or other
conveyance with concentrated, high-
velocity flows. Typical outlet protection
consists of riprap or rock aprons at the
conveyance outlet.
Appropriate Uses
Outlet protection should be used when a
conveyance discharges onto a disturbed
area where there is potential for accelerated
erosion due to concentrated flow. Outlet
protection should be provided where the velocity at the culvert outlet exceeds the maximum permissible
velocity of the material in the receiving channel.
Note: This Fact Sheet and detail are for temporary outlet protection, outlets that are intended to be used
for less than 2 years. For permanent, long-term outlet protection, see the Major Drainage chapter of
Volume 1.
Design and Installation
Design outlet protection to handle runoff from the largest drainage area that may be contributing runoff
during construction (the drainage area may change as a result of grading). Key in rock, around the entire
perimeter of the apron, to a minimum depth of 6 inches for stability. Extend riprap to the height of the
culvert or the normal flow depth of the downstream channel, whichever is less. Additional erosion
control measures such as vegetative lining, turf reinforcement mat and/or other channel lining methods
may be required downstream of the outlet protection if the channel is susceptible to erosion. See Design
Detail OP-1 for additional information.
Maintenance and Removal
Inspect apron for damage and displaced rocks. If rocks are missing or significantly displaced, repair or
replace as necessary. If rocks are continuously missing or displaced, consider increasing the size of the
riprap or deeper keying of the perimeter.
Remove sediment accumulated at the outlet before the outlet protection becomes buried and ineffective.
When sediment accumulation is noted, check that upgradient BMPs, including inlet protection, are in
effective operating condition.
Outlet protection may be removed once the pipe is no longer
draining an upstream area, or once the downstream area has
been sufficiently stabilized. If the drainage pipe is
permanent, outlet protection can be left in place; however,
permanent outlet protection should be designed and
constructed in accordance with the requirements of the
Major Drainage chapter of Volume 2.

tracking pad for access and sign.
Description
Concrete waste management involves
designating and properly managing a
specific area of the construction site as a
concrete washout area. A concrete
washout area can be created using one of
several approaches designed to receive
wash water from washing of tools and
concrete mixer chutes, liquid concrete
waste from dump trucks, mobile batch
mixers, or pump trucks. Three basic
approaches are available: excavation of a
pit in the ground, use of an above ground
storage area, or use of prefabricated haul-
away concrete washout containers.
Surface discharges of concrete washout
water from construction sites are prohibited.
Appropriate Uses
Concrete washout areas must be designated on all sites that will generate concrete wash water or liquid
concrete waste from onsite concrete mixing or concrete delivery.
Because pH is a pollutant of concern for washout activities, when unlined pits are used for concrete
washout, the soil must have adequate buffering capacity to result in protection of state groundwater
standards; otherwise, a liner/containment must be used. The following management practices are
recommended to prevent an impact from unlined pits to groundwater:
The use of the washout site should be temporary (less than 1 year), and
The washout site should be not be located in an area where shallow groundwater may be present, such
as near natural drainages, springs, or wetlands.
Design and Installation
Concrete washout activities must be conducted in a manner that does not contribute pollutants to surface
waters or stormwater runoff. Concrete washout areas may be lined or unlined excavated pits in the
ground, commercially manufactured prefabricated washout containers, or aboveground holding areas
constructed of berms, sandbags or straw bales with a plastic liner.
Although unlined washout areas may be used, lined pits may be required to protect groundwater under
certain conditions.
Do not locate an unlined washout area within 400 feet
of any natural drainage pathway or waterbody or
within 1,000 feet of any wells or drinking water
sources. Even for lined concrete washouts, it is
advisable to locate the facility away from waterbodies
and drainage paths. If site constraints make these

setbacks infeasible or if highly permeable soils exist in the area, then the pit must be installed with an
impermeable liner (16 mil minimum thickness) or surface storage alternatives using prefabricated
concrete washout devices or a lined aboveground storage area should be used.
Design details with notes are provided in Detail CWA-1 for pits and CWA-2 for aboveground storage
areas. Pre-fabricated concrete washout container information can be obtained from vendors.
Maintenance and Removal
A key consideration for concrete washout areas is to ensure that adequate signage is in place identifying
the location of the washout area. Part of inspecting and maintaining washout areas is ensuring that
adequate signage is provided and in good repair and that the washout area is being used, as opposed to
washout in non-designated areas of the site.
Remove concrete waste in the washout area, as needed to maintain BMP function (typically when filled to
about two-thirds of its capacity). Collect concrete waste and deliver offsite to a designated disposal
location.
Upon termination of use of the washout site, accumulated solid waste, including concrete waste and any
contaminated soils, must be removed from the site to prevent on-site disposal of solid waste. If the wash
water is allowed to evaporate and the concrete hardens, it may be recycled.

June 2012 Urban Drainage and Flood Control District TS/PS-1
Urban Storm Drainage Criteria Manual Volume 3
Photograph TS/PS -1. Equipment used to drill seed. Photo courtesy of
Douglas County.
Description
Temporary seeding can be used to
stabilize disturbed areas that will be
inactive for an extended period.
Permanent seeding should be used to
stabilize areas at final grade that will not
be otherwise stabilized. Effective seeding
includes preparation of a seedbed,
selection of an appropriate seed mixture,
proper planting techniques, and protection
of the seeded area with mulch, geotextiles,
or other appropriate measures.
Appropriate Uses
When the soil surface is disturbed and
will remain inactive for an extended
period (typically 30 days or longer),
proactive stabilization measures should be implemented. If the inactive period is short-lived (on the order
of two weeks), techniques such as surface roughening may be appropriate. For longer periods of
inactivity, temporary seeding and mulching can provide effective erosion control. Permanent seeding
should be used on finished areas that have not been otherwise stabilized.
Typically, local governments have their own seed mixes and timelines for seeding. Check jurisdictional
requirements for seeding and temporary stabilization.
Design and Installation
Effective seeding requires proper seedbed preparation, selection of an appropriate seed mixture, use of
appropriate seeding equipment to ensure proper coverage and density, and protection with mulch or fabric
until plants are established.
The USDCM Volume 2 Revegetation Chapter contains detailed seed mix, soil preparations, and seeding
and mulching recommendations that may be referenced to supplement this Fact Sheet.
Drill seeding is the preferred seeding method. Hydroseeding is not recommended except in areas where
steep slopes prevent use of drill seeding equipment, and even in these instances it is preferable to hand
seed and mulch. Some jurisdictions do not allow hydroseeding or hydromulching.
Seedbed Preparation
Prior to seeding, ensure that areas to be revegetated have
soil conditions capable of supporting vegetation. Overlot
grading can result in loss of topsoil, resulting in poor quality
subsoils at the ground surface that have low nutrient value,
little organic matter content, few soil microorganisms,
rooting restrictions, and conditions less conducive to
infiltration of precipitation. As a result, it is typically
necessary to provide stockpiled topsoil, compost, or other

soil amendments and rototill them into the soil to a depth of 6 inches or more.
Topsoil should be salvaged during grading operations for use and spread on areas to be revegetated later.
Topsoil should be viewed as an important resource to be utilized for vegetation establishment, due to its
water-holding capacity, structure, texture, organic matter content, biological activity, and nutrient content.
The rooting depth of most native grasses in the semi-arid Denver metropolitan area is 6 to 18 inches. At a
minimum, the upper 6 inches of topsoil should be stripped, stockpiled, and ultimately respread across
areas that will be revegetated.
Where topsoil is not available, subsoils should be amended to provide an appropriate plant-growth
medium. Organic matter, such as well digested compost, can be added to improve soil characteristics
conducive to plant growth. Other treatments can be used to adjust soil pH conditions when needed. Soil
testing, which is typically inexpensive, should be completed to determine and optimize the types and
amounts of amendments that are required.
If the disturbed ground surface is compacted, rip or rototill the surface prior to placing topsoil. If adding
compost to the existing soil surface, rototilling is necessary. Surface roughening will assist in placement
of a stable topsoil layer on steeper slopes, and allow infiltration and root penetration to greater depth.
Prior to seeding, the soil surface should be rough and the seedbed should be firm, but neither too loose
nor compacted. The upper layer of soil should be in a condition suitable for seeding at the proper depth
and conducive to plant growth. Seed-to-soil contact is the key to good germination.
Seed Mix for Temporary Vegetation
To provide temporary vegetative cover on disturbed areas which will not be paved, built upon, or fully
landscaped or worked for an extended period (typically 30 days or more), plant an annual grass
appropriate for the time of planting and mulch the planted areas. Annual grasses suitable for the Denver
metropolitan area are listed in Table TS/PS-1. These are to be considered only as general
recommendations when specific design guidance for a particular site is not available. Local governments
typically specify seed mixes appropriate for their jurisdiction.
Seed Mix for Permanent Revegetation
To provide vegetative cover on disturbed areas that have reached final grade, a perennial grass mix should
be established. Permanent seeding should be performed promptly (typically within 14 days) after
reaching final grade. Each site will have different characteristics and a landscape professional or the local
jurisdiction should be contacted to determine the most suitable seed mix for a specific site. In lieu of a
specific recommendation, one of the perennial grass mixes appropriate for site conditions and growth
season listed in Table TS/PS-2 can be used. The pure live seed (PLS) rates of application recommended
in these tables are considered to be absolute minimum rates for seed applied using proper drill-seeding
equipment.
If desired for wildlife habitat or landscape diversity, shrubs such as rubber rabbitbrush (Chrysothamnus
nauseosus), fourwing saltbush (Atriplex canescens) and skunkbrush sumac (Rhus trilobata) could be
added to the upland seedmixes at 0.25, 0.5 and 1 pound PLS/acre, respectively. In riparian zones,
planting root stock of such species as American plum (Prunus americana), woods rose (Rosa woodsii),
plains cottonwood (Populus sargentii), and willow (Populus spp.) may be considered. On non-topsoiled
upland sites, a legume such as Ladak alfalfa at 1 pound PLS/acre can be included as a source of nitrogen
for perennial grasses.

a Successful seeding of annual grass resulting in adequate plant growth will
usually produce enough dead-plant residue to provide protection from
wind and water erosion for an additional year. This assumes that the cover
is not disturbed or mowed closer than 8 inches.
Hydraulic seeding may be substituted for drilling only where slopes are
steeper than 3:1 or where access limitations exist. When hydraulic
seeding is used, hydraulic mulching should be applied as a separate
operation, when practical, to prevent the seeds from being encapsulated in
the mulch.
b See Table TS/PS-3 for seeding dates. Irrigation, if consistently applied,
may extend the use of cool season species during the summer months.
c Seeding rates should be doubled if seed is broadcast, or increased by 50

Mulch
Cover seeded areas with mulch or an appropriate rolled erosion control product to promote establishment
of vegetation. Anchor mulch by crimping, netting or use of a non-toxic tackifier. See the Mulching BMP
Fact Sheet for additional guidance.
Maintenance and Removal
Monitor and observe seeded areas to identify areas of poor growth or areas that fail to germinate. Reseed
and mulch these areas, as needed.
An area that has been permanently seeded should have a good stand of vegetation within one growing
season if irrigated and within three growing seasons without irrigation in Colorado. Reseed portions of
the site that fail to germinate or remain bare after the first growing season.
Seeded areas may require irrigation, particularly during extended dry periods. Targeted weed control may
also be necessary.
Protect seeded areas from construction equipment and vehicle access.
Stabilized Staging Area (SSA) SM-6
November 2010 Urban Drainage and Flood Control District SSA-1
Urban Storm Drainage Criteria Manual Volume 3
Photograph SSA-1. Example of a staging area with a gravel surface to
prevent mud tracking and reduce runoff. Photo courtesy of Douglas
County.
Description
A stabilized staging area is a clearly
designated area where construction
equipment and vehicles, stockpiles, waste
bins, and other construction-related
materials are stored. The contractor
office trailer may also be located in this
area. Depending on the size of the
construction site, more than one staging
area may be necessary.
Appropriate Uses
Most construction sites will require a
staging area, which should be clearly
designated in SWMP drawings. The layout
of the staging area may vary depending on
the type of construction activity. Staging areas located in roadways due to space constraints require
special measures to avoid materials being washed into storm inlets.
Design and Installation
Stabilized staging areas should be completed prior to other construction activities beginning on the site.
Major components of a stabilized staging area include:
Appropriate space to contain storage and provide for loading/unloading operations, as well as parking
if necessary.
A stabilized surface, either paved or covered, with 3-inch diameter aggregate or larger.
Perimeter controls such as silt fence, sediment control logs, or other measures.
Construction fencing to prevent unauthorized access to construction materials.
Provisions for Good Housekeeping practices related to materials storage and disposal, as described in
the Good Housekeeping BMP Fact Sheet.
A stabilized construction entrance/exit, as described in the Vehicle Tracking Control BMP Fact Sheet,
to accommodate traffic associated with material delivery and waste disposal vehicles.
Over -sizing the stabilized staging area may result in disturbance of existing vegetation in excess of that
required for the project. This increases costs, as well as
requirements for long-term stabilization following the
construction period. When designing the stabilized staging area,
minimize the area of disturbance to the extent practical.

SSA-2 Urban Drainage and Flood Control District November 2010
Urban Storm Drainage Criteria Manual Volume 3
See Detail SSA-1 for a typical stabilized staging area and SSA-2 for a stabilized staging area when
materials staging in roadways is required.
Maintenance and Removal
Maintenance of stabilized staging areas includes maintaining a stable surface cover of gravel, repairing
perimeter controls, and following good housekeeping practices.
When construction is complete, debris, unused stockpiles and materials should be recycled or properly
disposed. In some cases, this will require disposal of contaminated soil from equipment leaks in an
appropriate landfill. Staging areas should then be permanently stabilized with vegetation or other surface
cover planned for the development.
Minimizing Long-Term Stabilization Requirements
Utilize off-site parking and restrict vehicle access to the site.
Use construction mats in lieu of rock when staging is provided in an area that will not be disturbed
otherwise.
Consider use of a bermed contained area for materials and equipment that do not require a
stabilized surface.
Consider phasing of staging areas to avoid disturbance in an area that will not be otherwise
disturbed.

November 2010 Urban Drainage and Flood Control District SP-1
Urban Storm Drainage Criteria Manual Volume 3
Photograph SP-1. A topsoil stockpile that has been partially
revegetated and is protected by silt fence perimeter control.
Description
Stockpile management includes
measures to minimize erosion and
sediment transport from soil stockpiles.
Appropriate Uses
Stockpile management should be used
when soils or other erodible materials
are stored at the construction site.
Special attention should be given to
stockpiles in close proximity to natural
or manmade storm systems.
Design and Installation
Locate stockpiles away from all drainage system components including storm sewer inlets. Where
practical, choose stockpile locations that that will remain undisturbed for the longest period of time as the
phases of construction progress. Place sediment control BMPs around the perimeter of the stockpile, such
as sediment control logs, rock socks, silt fence, straw bales and sand bags. See Detail SP-1 for guidance
on proper establishment of perimeter controls around a stockpile. For stockpiles in active use, provide a
stabilized designated access point on the upgradient side of the stockpile.
Stabilize the stockpile surface with surface roughening, temporary seeding and mulching, erosion control
blankets, or soil binders. Soils stockpiled for an extended period (typically for more than 60 days) should
be seeded and mulched with a temporary grass cover once the stockpile is placed (typically within 14
days). Use of mulch only or a soil binder is acceptable if the stockpile will be in place for a more limited
time period (typically 30-60 days). Timeframes for stabilization of stockpiles noted in this fact sheet are
"typical" guidelines. Check permit requirements for specific federal, state, and/or local requirements that
may be more prescriptive.
Stockpiles should not be placed in streets or paved areas unless no other practical alternative exists. See
the Stabilized Staging Area Fact Sheet for guidance when staging in roadways is unavoidable due to
space or right-of-way constraints. For paved areas, rock socks must be used for perimeter control and all
inlets with the potential to receive sediment from the stockpile (even from vehicle tracking) must be
protected.
Maintenance and Removal
Inspect perimeter controls and inlet protection in accordance with their respective BMP Fact Sheets.
Where seeding, mulch and/or soil binders are used, reseeding or reapplication of soil binder may be
necessary.
When temporary removal of a perimeter BMP is necessary
to access a stockpile, ensure BMPs are reinstalled in
accordance with their respective design detail section.

Urban Storm Drainage Criteria Manual Volume 3
Photograph RS-1. Rock socks placed at regular intervals in a curb
line can help reduce sediment loading to storm sewer inlets. Rock
socks can also be used as perimeter controls.
Description
A rock sock is constructed of gravel
that has been wrapped by wire mesh or
a geotextile to form an elongated
cylindrical filter. Rock socks are
typically used either as a perimeter
control or as part of inlet protection.
When placed at angles in the curb line,
rock socks are typically referred to as
curb socks. Rock socks are intended to
trap sediment from stormwater runoff
that flows onto roadways as a result of
construction activities.
Appropriate Uses
Rock socks can be used at the perimeter
of a disturbed area to control localized
sediment loading. A benefit of rock
socks as opposed to other perimeter controls is that they do not have to be trenched or staked into the
ground; therefore, they are often used on roadway construction projects where paved surfaces are present.
Use rock socks in inlet protection applications when the construction of a roadway is substantially
complete and the roadway has been directly connected to a receiving storm system.
Design and Installation
When rock socks are used as perimeter controls, the maximum recommended tributary drainage area per
100 lineal feet of rock socks is approximately 0.25 acres with disturbed slope length of up to 150 feet and
a tributary slope gradient no steeper than 3:1. A rock sock design detail and notes are provided in Detail
RS-1. Also see the Inlet Protection Fact Sheet for design and installation guidance when rock socks are
used for inlet protection and in the curb line.
When placed in the gutter adjacent to a curb, rock socks should protrude no more than two feet from the
curb in order for traffic to pass safely. If located in a high traffic area, place construction markers to alert
drivers and street maintenance workers of their presence.
Maintenance and Removal
Rock socks are susceptible to displacement and breaking due to vehicle traffic. Inspect rock socks for
damage and repair or replace as necessary. Remove sediment by sweeping or vacuuming as needed to
maintain the functionality of the BMP, typically when sediment
has accumulated behind the rock sock to one-half of the sock's
height.
Once upstream stabilization is complete, rock socks and
accumulated sediment should be removed and properly disposed.

CONTRACTOR, SUB-CONTRACTORS, OR SIMILAR TITLE FOR THE DEVELOPING ENTITY (HERE AFTER REFERRED TO
AS THE DEVELOPER) HAS PROVIDED THESE EROSION CONTROL MATERIALS IN ACCORDANCE WITH EROSION
CONTROL CRITERIA SET FORTH IN THE MANUAL AS AN ATTEMPT TO IDENTIFY EROSION, SEDIMENT, AND OTHER
POTENTIAL POLLUTANT SOURCES ASSOCIATED WITH THESE CONSTRUCTION ACTIVITIES AND PREVENTING
THOSE POLLUTANTS FROM LEAVING THE PROJECT SITE AS AN ILLICIT DISCHARGE. FULL CITY REQUIREMENTS AND
ARE OUTLINED AND CLARIFIED IN THE MANUAL UNDER CHAPTER 4: CONSTRUCTION CONTROL MEASURES AND
SHOULD BE USED TO IDENTIFY AND DEFINE WHAT IS NEEDED ON A PROJECT.
2.THE DEVELOPER SHALL MAKE THEMSELVES THOROUGHLY FAMILIAR WITH THE PROVISIONS AND THE CONTENT
OF THE SPECIFICATIONS LAID OUT IN THE MANUAL, THE DEVELOPMENT AGREEMENT, THE EROSION CONTROL
MATERIALS COMPILED FOR THIS PROJECT, AND THE FOLLOWING NOTES AS ALL THESE MATERIALS ARE
APPLICABLE TO THIS PROJECT.
3.THE DEVELOPER SHALL IMPLEMENT AND MAINTAIN CONTROL MEASURES FOR ALL POTENTIAL POLLUTANTS
FROM THE START OF LAND DISTURBING ACTIVITIES UNTIL FINAL STABILIZATION OF THE CONSTRUCTION SITE.
4.THE CITY EROSION CONTROL INSPECTOR SHALL BE NOTIFIED AT LEAST TWENTY-FOUR (24) HOURS PRIOR TO
THE DESIRED START OF ANY CONSTRUCTION ACTIVITIES ON THIS SITE TO ALLOW ADEQUATE TIME FOR ON-SITE
CONFIRMATION (INITIAL INSPECTION WHICH CAN TAKE UP TO TWO BUSINESS DAYS AFTER RECEIVING THE
REQUEST) THAT THE SITE IS IN FACT PROTECTED FROM SEDIMENT AND POLLUTANTS DISCHARGES OFF SITE.
PLEASE CONTACT EROSION@FCGOV.COM EARLY TO SCHEDULE THOSE INITIAL EROSION CONTROL INSPECTIONS
WELL IN ADVANCE SO THAT DEMOLITION, CLEARING, GRUBBING, TREE REMOVAL, AND SCRAPING MAY BEGIN
WITHOUT DELAY. FAILURE TO RECEIVE AN ON-SITE CONFIRMATION BEFORE CONSTRUCTION ACTIVITIES
COMMENCE IS AN AUTOMATIC “NOTICE OF VIOLATION” AND CAN RESULT IN FURTHER ENFORCEMENT
ACTIONS.
5.THE DEVELOPER SHALL PROACTIVELY PROVIDE ALL APPROPRIATE CONTROL MEASURES TO PREVENT DAMAGE
TO ADJACENT DOWNSTREAM AND LEEWARD PROPERTIES. THIS INCLUDES BUT IS NOT LIMITED TO: TREES,
SHRUBS, LAWNS, WALKS, PAVEMENTS, ROADWAYS, STRUCTURES, CREEKS, WETLANDS, STREAMS, RIVERS, AND
UTILITIES THAT ARE NOT DESIGNED FOR REMOVAL, RELOCATION, OR REPLACEMENT IN THE COURSE OF
CONSTRUCTION.
6.AT ALL TIMES THE DEVELOPER SHALL BE RESPONSIBLE TO ENSURE ADEQUATE CONTROL MEASURES ARE
DESIGNED, SELECTED, INSTALLED, MAINTAIN, REPAIRED, REPLACED, AND ULTIMATELY REMOVED IN ORDER
TO PREVENT AND CONTROL EROSION SUSPENSION, SEDIMENT TRANSPORTATION, AND POLLUTANT DISCHARGE
AS A RESULT OF CONSTRUCTION ACTIVITIES ASSOCIATED WITH THIS PROJECT.
7.ALL APPLICABLE CONTROL MEASURES BASED UPON THE SEQUENCING AND/OR PHASING OF THE PROJECT
SHALL BE INSTALLED PRIOR TO THOSE CONSTRUCTION ACTIVITIES COMMENCING.
8.AS DYNAMIC CONDITIONS (DUE TO THE NATURE, TIMING, SEQUENCE, AND PHASING OF CONSTRUCTION) IN
THE FIELD MAY WARRANT CONTROL MEASURES IN ADDITION, OR DIFFERENT, TO WHAT IS SHOWN ON THESE
PLANS, THE DEVELOPER SHALL AT ALL TIMES BE RESPONSIBLE TO IMPLEMENT THE CONTROL MEASURES THAT
ARE MOST EFFECTIVE WITH THE CURRENT STATE AND PROGRESS OF CONSTRUCTION. THE DEVELOPER SHALL
IMPLEMENT WHATEVER MEASURES ARE DETERMINED NECESSARY, AND/OR AS DIRECTED BY THE CITY
EROSION CONTROL INSPECTOR. THE DEVELOPER SHALL INSURE THAT ALL EROSION CONTROL PLANS (MAPS) OR
SWMP DOCUMENTS ARE UPDATED TO REFLECT THE CURRENT SITE CONDITIONS, WITH UPDATES BEING
INITIALED AND DATED. THESE SITE INSPECTIONS AND SITE CONDITION UPDATES SHALL BE MADE AVAILABLE
UPON REQUEST BY THE CITY.
9.ALL LISTINGS, PROVISIONS, MATERIALS, PROCEDURES, ACTIVITIES, SITE WORK AND THE LIKE ARTICULATED IN
THIS OR OTHER WRITTEN SITE-SPECIFIC DOCUMENTS (INCLUDING BUT NOT LIMITED TO THE EROSION CONTROL
REPORTS, DEVELOPMENT AGREEMENTS, LANDSCAPE, AND DRAINAGE MATERIALS) SHALL MEET OR EXCEED
THE MOST RESTRICTIVE LANGUAGE FOR CITY, COUNTY, STATE, AND FEDERAL REGULATIONS WITH REGARDS TO
EROSION, SEDIMENT, POLLUTANT, AND OTHER POLLUTION SOURCE CONTROL MEASURES. THE DEVELOPER
SHALL BE RESPONSIBLE TO COMPLY WITH ALL OF THESE AFOREMENTIONED LAWS AND REGULATIONS.
10.THE DEVELOPER SHALL ENSURE THAT ALL APPROPRIATE PERMITS (CDPS GENERAL PERMIT STORMWATER

DUE TO INCONSISTENCIES IN CONSTRUCTION PLANS FOR THE SITE OR SITE CONDITIONS AROUND THE SELECTED
CONTROL MEASURES BY CONTACTING THE EROSION CONTROL INSPECTOR. THE EROSION CONTROL INSPECTOR
WILL NOT BE RESPONSIBLE FOR ANY EXPLANATIONS, INTERPRETATIONS, OR SUPPLEMENTARY DATA PROVIDED
BY OTHERS.
13.ALL CONTROL MEASURES SHALL BE INSTALLED IN ACCORDANCE WITH THE MANUAL.
14.THE CITY RESERVES THE RIGHT TO REQUIRE ADDITIONAL CONTROL MEASURES AS SITE CONDITIONS WARRANT,
TO THE EXTENT AUTHORIZED BY RELEVANT LEGAL AUTHORITY.
15.AS WITH ANY CONSTRUCTION STANDARDS, OCCASIONS MAY ARISE WHERE THE MINIMUM EROSION CONTROL
STANDARDS ARE EITHER INAPPROPRIATE OR CANNOT BE JUSTIFIED. IN THESE CASES, A VARIANCE TO THESE
STANDARDS MAY BE APPLIED FOR PURSUANT TO THE TERMS, CONDITIONS, AND PROCEDURES OF THE
MANUAL.
16.INSPECTION. THE CONTRACTOR SHALL INSPECT SITE POLLUTANT SOURCES AND IMPLEMENT CONTROL
MEASURES AT A MINIMUM OF ONCE EVERY TWO WEEKS DURING CONSTRUCTION AND WITHIN 24 HOURS
