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 the required erosion control measures shall 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 (e.g., 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 fourteen-(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
East Ridge Third Filing Replat – Mosaic Townhomes (ERTF) is located within East
Ridge Second Filing (ERSF). ERTF Replat will develop Tract A of ERSF (Phases 8
and 9 of the Phasing Plan.)
East Ridge Second Filing (hereafter referred to as “ERSF”) is located southeast of the
intersection of East Vine Drive and Timberline Road. More specifically, the site is
located in the Northeast Quarter of Section 8, Township 7 North, Range 68 West in the
City of Fort Collins, County of Larimer and State of Colorado. Refer to Appendix A for a
Vicinity Map.
Project Coordinate Location:
· Longitude 105°01'29.3"W
· Latitude 40°35'32.8"N
CDPS Permit #: COR401471
*A copy of the permit is available in Appendix F. Permit COR401471 was recorded in April 2019 as CDPHE
updated requirements. Permit COR401471 is based on the application for modification of the previous permit,
COR03P829. Therefore, the application for modification of permit COR03P829 is included in Appendix F to show
the details and area of disturbance included.
ii. Description of Adjacent Areas
The larger site is bounded on north by the Burlington Northern Railroad and East Vine
Drive; on the south by an existing construction material recycling operation (i.e., Barker
Property); on the east by undeveloped agricultural land; and on the west by Timberline
Road and Collins Aire Park – a mobile home park. The Larimer-Weld Canal is located north
of the site, and the Lake Canal, which will serve as the temporary outfall, is located to the
south.
The larger ERSF project site consists of ±153.29 acres and is in the process of being
developed. Site grading, utility and roadway construction is on-going. ERTF was overlot
graded per the approved (dated June 30th, 2016) utility plans for ERSF. The maximum
elevation difference across the site is ±27 feet. The smaller ERTF Replat project site
consists of ±10.84 acres.
The surface runoff generally flows overland across overlot graded lot areas; into the right-
of-way; and then into the storm drain systems through combination type curb inlets. The
storm drain systems outlet into water quality features and, ultimately, into the on-site
detention pond in the south central region 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: December 2019
- Estimated project completion date: To Be Determined
Major Phases of Construction:
* Portions of the following have been Completed or are On-Going and noted as such.
* 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, On-Going.
- Overlot grade the site. This will include grading the stormwater quality features and
detention pond. Future phases of the development should will be seeded and mulched,
Completed.
- Install Phase I utilities (e.g., domestic water, sanitary sewer and storm sewer). Utilities
associated with other phases needed to service ERTF have been installed, Completed.
- Construct Phase I internal roadways, Completed.
- 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 curb inlets, On-Going.
- 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, On-Going.
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 sheets LP101.
C. AREA OF DISTURBANCE
The total area of the site within the project boundaries is ±153.29 acres. The overlot grading,
utility installation and roadway construction will account for ±153.29 acres of land disturbance
within the project. Specifically, ERTF Replat will disturb ±10.8 acres of area within the project
boundary which was overlot graded.
Earthwork estimates (ERSF):
- Cut of 297,847 cubic yards (Completed)
- Fill of 292,751 cubic yards (Completed)
- Net Cut of 5,096 cubic yards (Completed)
D. TOPOGRAPHY, SOILS AND RAINFALL DATA
The existing grades in the north half of the site average one percent. The existing grades in
the south half are steeper and average three percent. The existing runoff generally flows to an
existing low-lying wetland area in the south-central region of the site. This low area has no
natural outfall. The maximum elevation difference across the site is ±27 feet (4956 – 4929).
According to the USDA NRCS Web Soil Survey, ‘Fort Collins loam, 0 to 3 percent slopes’
covers roughly two-thirds of the project site. 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, growing alfalfa. The ground cover across the existing site
consists of native grasses and weeds. The existing percent vegetation cover was very good,
±75%. For a site of this size, the number of existing trees is limited; only a few along
Timberline Road and the natural low point.
The overlot graded areas have been roughened or disked and mulched.
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 (i.e., sheet EC01) 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 sheet EC01. 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 will need 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 larger ERSF site drains to a detention pond in the south-central region of the larger project
site. The detention pond was constructed in the same location as the existing wetland area.
The temporary outfall pumps water ±1050 l.f. south to the Lake Canal Ditch. Five-(5)
stormwater quality features surround the detention pond. These features include: a Bioswale
(GS), two-(2) Extended Detention Basins (EDB) and two-(2) Sand Filters (SF). The developed
site runoff passes through one of the stormwater quality features before it flows into the
detention pond.
We are in the process of developing a design for the permanent outfall. At a high level, we
anticipate the outfall will convey detained runoff west to the west side of Timberline Road and
then south to Dry Creek.
The wetland area disturbance and enhancement guidelines and details are described in a
report prepared by Cedar Creek Associates.
I. SITE FEATURES AND SENSITVE AREAS TO BE PROTECTED
The developed ERTF Replat site will drain to the on-site detention pond located in ERSF. The
lowest region of the detention pond is an active wetland and is considered a sensitive area to
be protected. Therefore, the developed site runoff must pass through a stormwater quality
feature before it enters the proposed on-site detention pond. Additional details concerning this
area are available in a report prepared by Cedar Creek Associates.
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 because of contact with the fuel
stored, and can contain 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 EC01 and EC02. Prior to construction
of any concrete fixtures a Concrete Washout Area (CWA) shall be installed on site as shown
on the EC01 and EC02. 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 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 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. Additionally, 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 the CDPS General Permit for Stormwater Discharges Associated
with Construction Activity (COR-400000) (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
In general, the project will be developed in phases. The area to be developed in
Phases 8 and 9 is shaded on PH01. The areas of the site that are associated with
future phases 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 times 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) 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 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, 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.

Description
Effective construction site management
to minimize erosion and sediment
transport includes attention to
construction phasing, scheduling, and
sequencing of land disturbing activities.
On most construction projects, erosion
and sediment controls will need to be
adjusted as the project progresses and
should be documented in the SWMP.
Construction phasing refers to
disturbing only part of a site at a time to
limit the potential for erosion from
dormant parts of a site. Grading
activities and construction are completed
and soils are effectively stabilized on one
part of a site before grading and
construction begins on another portion of the site.
Construction sequencing or scheduling refers to a specified work schedule that coordinates the timing of
land disturbing activities and the installation of erosion and sediment control practices.
Appropriate Uses
All construction projects can benefit from upfront planning to phase and sequence construction activities
to minimize the extent and duration of disturbance. Larger projects and linear construction projects may
benefit most from construction sequencing or phasing, but even small projects can benefit from
construction sequencing that minimizes the duration of disturbance.
Typically, erosion and sediment controls needed at a site will change as a site progresses through the
major phases of construction. Erosion and sediment control practices corresponding to each phase of
construction must be documented in the SWMP.
Design and Installation
BMPs appropriate to the major phases of development should be identified on construction drawings. In
some cases, it will be necessary to provide several drawings showing construction-phase BMPs placed
according to stages of development (e.g., clearing and grading, utility installation, active construction,
final stabilization). Some municipalities in the Denver area set maximum sizes for disturbed area
associated with phases of a construction project. Additionally, requirements for phased construction
drawings vary among local governments within the UDFCD boundary. Some local governments require
separate erosion and sediment control drawings for initial
BMPs, interim conditions (in active construction), and final
stabilization.

CP-2 Urban Drainage and Flood Control District November 2010
Urban Storm Drainage Criteria Manual Volume 3
Typical construction phasing BMPs include:
Limit the amount of disturbed area at any given time on a site to the extent practical. For example, a
100-acre subdivision might be constructed in five phases of 20 acres each.
If there is carryover of stockpiled material from one phase to the next, position carryover material in a
location easily accessible for the pending phase that will not require disturbance of stabilized areas to
access the stockpile. Particularly with regard to efforts to balance cut and fill at a site, careful
planning for location of stockpiles is important.
Typical construction sequencing BMPs include:
Sequence construction activities to minimize duration of soil disturbance and exposure. For example,
when multiple utilities will occupy the same trench, schedule installation so that the trench does not
have to be closed and opened multiple times.
Schedule site stabilization activities (e.g., landscaping, seeding and mulching, installation of erosion
control blankets) as soon as feasible following grading.
Install initial erosion and sediment control practices before construction begins. Promptly install
additional BMPs for inlet protection, stabilization, etc., as construction activities are completed.
Table CP-1 provides typical sequencing of construction activities and associated BMPs.
Maintenance and Removal
When the construction schedule is altered, erosion and sediment control measures in the SWMP and
construction drawings should be appropriately adjusted to reflect actual "on the ground" conditions at the
construction site. Be aware that changes in construction schedules can have significant implications for
site stabilization, particularly with regard to establishment of vegetative cover.

Site Access
Install sediment controls downgradient of access point (on paved streets this may consist
of inlet protection).
Establish vehicle tracking control at entrances to paved streets. Fence as needed.
Use construction fencing to define the boundaries of the project and limit access to areas of
the site that are not to be disturbed.
Note: it may be necessary to protect inlets in the general vicinity of the site, even if not
downgradient, if there is a possibility that sediment tracked from the site could contribute
to the inlets.
Site Clearing
and Grubbing
Install perimeter controls as needed on downgradient perimeter of site (silt fence, wattles,
etc).
Limit disturbance to those areas planned for disturbance and protect undisturbed areas
within the site (construction fence, flagging, etc).
Preserve vegetative buffer at site perimeter.
Create stabilized staging area.
Locate portable toilets on flat surfaces away from drainage paths. Stake in areas
susceptible to high winds.
Construct concrete washout area and provide signage.
Establish waste disposal areas.
Install sediment basins.
Create dirt perimeter berms and/or brush barriers during grubbing and clearing.
Separate and stockpile topsoil, leave roughened and/or cover.
Protect stockpiles with perimeter control BMPs. Stockpiles should be located away from
drainage paths and should be accessed from the upgradient side so that perimeter controls
can remain in place on the downgradient side. Use erosion control blankets, temporary
seeding, and/or mulch for stockpiles that will be inactive for an extended period.
Leave disturbed area of site in a roughened condition to limit erosion. Consider temporary
revegetation for areas of the site that have been disturbed but that will be inactive for an
extended period.
Water to minimize dust but not to the point that watering creates runoff.

Silt Fence (SF) SC-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.

the contour, a "J-hook" installation may be appropriate
to ensure that the BMP does not create concentrated
flow parallel to the silt fence. Photo courtesy of Tom
Gore.
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.

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.

CIP-1. Culvert Inlet Protection
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.

November 2010 Urban Drainage and Flood Control District RS-1
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.

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 other fibrous
material trenched into the ground and
held with a wooden stake. Sediment
control logs are also often referred to
as "straw wattles." They 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.

SCL-2 Urban Drainage and Flood Control District November 2010
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 is if they are impermeable.
Design details and notes for sediment control logs are provided in Detail SCL-1. Sediment logs must be
properly trenched and staked into the ground 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, 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
recommended when used in perimeter control, inlet protection and check dam applications.

Description
Implement construction site good housekeeping practices to
prevent pollution associated with solid, liquid and hazardous
construction-related materials and wastes. Stormwater
Management Plans (SWMPs) should clearly specify BMPs
including these good housekeeping practices:
Provide for waste management.
Establish proper building material staging areas.
Designate paint and concrete washout areas.
Establish proper equipment/vehicle fueling and
maintenance practices.
Control equipment/vehicle washing and allowable non-
stormwater discharges.
Develop a spill prevention and response plan.
Acknowledgement: This Fact Sheet is based directly on
EPA guidance provided in Developing Your Stormwater
Pollution Prevent Plan (EPA 2007).
Appropriate Uses
Good housekeeping practices are necessary at all construction sites.
Design and Installation
The following principles and actions should be addressed in SWMPs:
Provide for Waste Management. Implement management procedures and practices to prevent or
reduce the exposure and transport of pollutants in stormwater from solid, liquid and sanitary wastes
that will be generated at the site. Practices such as trash disposal, recycling, proper material handling,
and cleanup measures can reduce the potential for stormwater runoff to pick up construction site
wastes and discharge them to surface waters. Implement a comprehensive set of waste-management
practices for hazardous or toxic materials, such as paints, solvents, petroleum products, pesticides,
wood preservatives, acids, roofing tar, and other materials. Practices should include storage,
handling, inventory, and cleanup procedures, in case of spills. Specific practices that should be
considered include:

o Recycle materials whenever possible (e.g., paper, wood, concrete, oil).
o Segregate and provide proper disposal options for hazardous material wastes.
o Clean up litter and debris from the construction site daily.
o Locate waste-collection areas away from streets, gutters, watercourses, and storm drains. Waste-
collection areas (dumpsters, and such) are often best located near construction site entrances to
minimize traffic on disturbed soils. Consider secondary containment around waste collection
areas to minimize the likelihood of contaminated discharges.
o Empty waste containers before they are full and overflowing.
Sanitary and Septic Waste
o Provide convenient, well-maintained, and properly located toilet facilities on-site.
o Locate toilet facilities away from storm drain inlets and waterways to prevent accidental spills
and contamination of stormwater.
o Maintain clean restroom facilities and empty portable toilets regularly.
o Where possible, provide secondary containment pans under portable toilets.
o Provide tie-downs or stake-downs for portable toilets.
o Educate employees, subcontractors, and suppliers on locations of facilities.
o Treat or dispose of sanitary and septic waste in accordance with state or local regulations. Do not
discharge or bury wastewater at the construction site.
o Inspect facilities for leaks. If found, repair or replace immediately.
o Special care is necessary during maintenance (pump out) to ensure that waste and/or biocide are
not spilled on the ground.
Hazardous Materials and Wastes
o Develop and implement employee and
subcontractor education, as needed, on
hazardous and toxic waste handling,
storage, disposal, and cleanup.
o Designate hazardous waste-collection
areas on-site.
o Place all hazardous and toxic material
wastes in secondary containment.
Good Housekeeping Practices (GH) MM-3
November 2010 Urban Drainage and Flood Control District GH-3
Urban Storm Drainage Criteria Manual Volume 3
o Hazardous waste containers should be inspected to ensure that all containers are labeled properly
and that no leaks are present.
Establish Proper Building Material Handling and Staging Areas. The SWMP should include
comprehensive handling and management procedures for building materials, especially those that are
hazardous or toxic. Paints, solvents, pesticides, fuels and oils, other hazardous materials or building
materials that have the potential to contaminate stormwater should be stored indoors or under cover
whenever possible or in areas with secondary containment. Secondary containment measures prevent
a spill from spreading across the site and may include dikes, berms, curbing, or other containment
methods. Secondary containment techniques should also ensure the protection of groundwater.
Designate staging areas for activities such as fueling vehicles, mixing paints, plaster, mortar, and
other potential pollutants. Designated staging areas enable easier monitoring of the use of materials
and clean up of spills. Training employees and subcontractors is essential to the success of this
pollution prevention principle. Consider the following specific materials handling and staging
practices:
o Train employees and subcontractors in proper handling and storage practices.
o Clearly designate site areas for staging and storage with signs and on construction drawings.
Staging areas should be located in areas central to the construction site. Segment the staging area
into sub-areas designated for vehicles, equipment, or stockpiles. Construction entrances and exits
should be clearly marked so that delivery vehicles enter/exit through stabilized areas with vehicle
tracking controls (See Vehicle Tracking Control Fact Sheet).
o Provide storage in accordance with Spill Protection, Control and Countermeasures (SPCC)
requirements and plans and provide cover and impermeable perimeter control, as necessary, for
hazardous materials and contaminated soils that must be stored on site.
o Ensure that storage containers are regularly inspected for leaks, corrosion, support or foundation
failure, or other signs of deterioration and tested for soundness.
o Reuse and recycle construction materials when possible.
Designate Concrete Washout Areas. Concrete contractors should be encouraged to use the washout
facilities at their own plants or dispatch facilities when feasible; however, concrete washout
commonly occurs on construction sites. If it is necessary to provide for concrete washout areas on-
site, designate specific washout areas and design facilities to handle anticipated washout water.
Washout areas should also be provided for paint and stucco operations. Because washout areas can
be a source of pollutants from leaks or spills, care must be taken with regard to their placement and
proper use. See the Concrete Washout Area Fact Sheet for detailed guidance.
Both self-constructed and prefabricated washout containers can fill up quickly when concrete, paint,
and stucco work are occurring on large portions of the site. Be sure to check for evidence that
contractors are using the washout areas and not dumping materials onto the ground or into drainage
facilities. If the washout areas are not being used regularly, consider posting additional signage,
relocating the facilities to more convenient locations, or providing training to workers and
contractors.
When concrete, paint, or stucco is part of the construction process, consider these practices which will
help prevent contamination of stormwater. Include the locations of these areas and the maintenance
and inspection procedures in the SWMP.
MM-3 Good Housekeeping Practices (GH)
GH-4 Urban Drainage and Flood Control District November 2010
Urban Storm Drainage Criteria Manual Volume 3
o Do not washout concrete trucks or equipment into storm drains, streets, gutters, uncontained
areas, or streams. Only use designated washout areas.
o Establish washout areas and advertise their locations with signs. Ensure that signage remains in
good repair.
o Provide adequate containment for the amount of wash water that will be used.
o Inspect washout structures daily to detect leaks or tears and to identify when materials need to be
removed.
o Dispose of materials properly. The preferred method is to allow the water to evaporate and to
recycle the hardened concrete. Full service companies may provide dewatering services and
should dispose of wastewater properly. Concrete wash water can be highly polluted. It should
not be discharged to any surface water, storm sewer system, or allowed to infiltrate into the
ground in the vicinity of waterbodies. Washwater should not be discharged to a sanitary sewer
system without first receiving written permission from the system operator.
Establish Proper Equipment/Vehicle Fueling and Maintenance Practices. Create a clearly
designated on-site fueling and maintenance area that is clean and dry. The on-site fueling area should
have a spill kit, and staff should know how to use it. If possible, conduct vehicle fueling and
maintenance activities in a covered area. Consider the following practices to help prevent the
discharge of pollutants to stormwater from equipment/vehicle fueling and maintenance. Include the
locations of designated fueling and maintenance areas and inspection and maintenance procedures in
the SWMP.
o Train employees and subcontractors in proper fueling procedures (stay with vehicles during
fueling, proper use of pumps, emergency shutoff valves, etc.).
o Inspect on-site vehicles and equipment regularly for leaks, equipment damage, and other service
problems.
o Clearly designate vehicle/equipment service areas away from drainage facilities and watercourses
to prevent stormwater run-on and runoff.
o Use drip pans, drip cloths, or absorbent pads when replacing spent fluids.
o Collect all spent fluids, store in appropriate labeled containers in the proper storage areas, and
recycle fluids whenever possible.
Control Equipment/Vehicle Washing and Allowable Non-Stormwater Discharges. Implement
practices to prevent contamination of surface and groundwater from equipment and vehicle wash
water. Representative practices include:
o Educate employees and subcontractors on proper washing procedures.
o Use off-site washing facilities, when available.
o Clearly mark the washing areas and inform workers that all washing must occur in this area.
o Contain wash water and treat it using BMPs. Infiltrate washwater when possible, but maintain
separation from drainage paths and waterbodies.
Good Housekeeping Practices (GH) MM-3
November 2010 Urban Drainage and Flood Control District GH-5
Urban Storm Drainage Criteria Manual Volume 3
o Use high-pressure water spray at vehicle washing facilities without detergents. Water alone can
remove most dirt adequately.
o Do not conduct other activities, such as vehicle repairs, in the wash area.
o Include the location of the washing facilities and the inspection and maintenance procedures in
the SWMP.
Develop a Spill Prevention and Response Plan. Spill prevention and response procedures must be
identified in the SWMP. Representative procedures include identifying ways to reduce the chance of
spills, stop the source of spills, contain and clean up spills, dispose of materials contaminated by
spills, and train personnel responsible for spill prevention and response. The plan should also specify
material handling procedures and storage requirements and ensure that clear and concise spill cleanup
procedures are provided and posted for areas in which spills may potentially occur. When developing
a spill prevention plan, include the following:
o Note the locations of chemical storage areas, storm drains, tributary drainage areas, surface
waterbodies on or near the site, and measures to stop spills from leaving the site.
o Provide proper handling and safety procedures for each type of waste. Keep Material Safety Data
Sheets (MSDSs) for chemical used on site with the SWMP.
o Establish an education program for employees and subcontractors on the potential hazards to
humans and the environment from spills and leaks.
o Specify how to notify appropriate authorities, such as police and fire departments, hospitals, or
municipal sewage treatment facilities to request assistance. Emergency procedures and contact
numbers should be provided in the SWMP and posted at storage locations.
o Describe the procedures, equipment and materials for immediate cleanup of spills and proper
disposal.
o Identify personnel responsible for implementing the plan in the event of a spill. Update the spill
prevention plan and clean up materials as changes occur to the types of chemicals stored and used
at the facility.

Maintenance and Removal
Effective implementation of good housekeeping practices is dependent on clear designation of personnel
responsible for supervising and implementing good housekeeping programs, such as site cleanup and
disposal of trash and debris, hazardous material management and disposal, vehicle and equipment
maintenance, and other practices. Emergency response "drills" may aid in emergency preparedness.
Checklists may be helpful in good housekeeping efforts.
Staging and storage areas require permanent stabilization when the areas are no longer being used for
construction-related activities.
Construction-related materials, debris and waste must be removed from the construction site once
construction is complete.
Design Details
See the following Fact Sheets for related Design Details:

Design details are not necessary for other good housekeeping practices; however, be sure to designate
where specific practices will occur on the appropriate construction drawings.
Stockpile Management (SP) MM-2
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.

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.

Rough Cut Street Control (RCS) EC-9
November 2010 Urban Drainage and Flood Control District RCS-1
Urban Storm Drainage Criteria Manual Volume 3
Photograph RCS-1. Rough cut street controls.
Description
Rough cut street controls are rock or
earthen berms placed along dirt roadways
that are under construction or used for
construction access. These temporary
berms intercept sheet flow and divert
runoff from the roadway, and control
erosion by minimizing concentration of
flow and reducing runoff velocity.
Appropriate Uses
Appropriate uses include:
Temporary dirt construction roadways
that have not received roadbase.
Roadways under construction that will not be paved within 14 days of final grading, and that have not
yet received roadbase.
Design and Installation
Rough cut street controls are designed to redirect sheet flow off the dirt roadway to prevent water from
concentrating and eroding the soil. These controls consist of runoff barriers that are constructed at
intervals along the road. These barriers are installed perpendicular to the longitudinal slope from the
outer edge of the roadside swale to the crown of the road. The barriers are positioned alternately from the
right and left side of the road to allow construction traffic to pass in the lane not barred. If construction
traffic is expected to be congested and a vehicle tracking control has been constructed, rough-cut street
controls may be omitted for 400 feet from the entrance. Runoff from the controls should be directed to
another stormwater BMP such as a roadside swale with check dams once removed from the roadway. See
Detail RCS-1 for additional information.
Maintenance and Removal
Inspect street controls for erosion and stability. If rills are forming in the roadway or cutting through the
control berms, place the street controls at shorter intervals. If earthen berms are used, periodic
recompaction may be necessary. When rock berms are used,
repair and/or replace as necessary when damaged. Street
controls may be removed 14 days prior to road surfacing and
paving.

Mulching (MU) EC-4
June 2012 Urban Drainage and Flood Control District MU-1
Urban Storm Drainage Criteria Manual Volume 3
Photograph MU-1. An area that was recently seeded, mulched,
and crimped.
Description
Mulching consists of evenly applying
straw, hay, shredded wood mulch, rock,
bark or compost to disturbed soils and
securing the mulch by crimping, tackifiers,
netting or other measures. Mulching helps
reduce erosion by protecting bare soil
from rainfall impact, increasing
infiltration, and reducing runoff.
Although often applied in conjunction
with temporary or permanent seeding, it
can also be used for temporary
stabilization of areas that cannot be
reseeded due to seasonal constraints.
Mulch can be applied either using
standard mechanical dry application
methods or using hydromulching equipment
that hydraulically applies a slurry of water,
wood fiber mulch, and often a tackifier.
Appropriate Uses
Use mulch in conjunction with seeding to help protect the seedbed and stabilize the soil. Mulch can also
be used as a temporary cover on low to mild slopes to help temporarily stabilize disturbed areas where
growing season constraints prevent effective reseeding. Disturbed areas should be properly mulched and
tacked, or seeded, mulched and tacked promptly after final grade is reached (typically within no longer
than 14 days) on portions of the site not otherwise permanently stabilized.
Standard dry mulching is encouraged in most jurisdictions; however, hydromulching may not be allowed
in certain jurisdictions or may not be allowed near waterways.
Do not apply mulch during windy conditions.
Design and Installation
Prior to mulching, surface-roughen areas by rolling with a crimping or punching type roller or by track
walking. Track walking should only be used where other methods are impractical because track walking
with heavy equipment typically compacts the soil.
A variety of mulches can be used effectively at construction
sites. Consider the following:

EC-4 Mulching (MU)
MU-2 Urban Drainage and Flood Control District June 2012
Urban Storm Drainage Criteria Manual Volume 3
Clean, weed-free and seed-free cereal grain straw should be applied evenly at a rate of 2 tons per acre and
must be tacked or fastened by a method suitable for the condition of the site. Straw mulch must be
anchored (and not merely placed) on the surface. This can be accomplished mechanically by crimping or
with the aid of tackifiers or nets. Anchoring with a crimping implement is preferred, and is the
recommended method for areas flatter than 3:1. Mechanical crimpers must be capable of tucking the long
mulch fibers into the soil to a depth of 3 inches without cutting them. An agricultural disk, while not an
ideal substitute, may work if the disk blades are dull or blunted and set vertically; however, the frame may
have to be weighted to afford proper soil penetration.
Grass hay may be used in place of straw; however, because hay is comprised of the entire plant including
seed, mulching with hay may seed the site with non-native grass species which might in turn out-compete
the native seed. Alternatively, native species of grass hay may be purchased, but can be difficult to find
and are more expensive than straw. Purchasing and utilizing a certified weed-free straw is an easier and
less costly mulching method. When using grass hay, follow the same guidelines as for straw (provided
above).
On small areas sheltered from the wind and heavy runoff, spraying a tackifier on the mulch is satisfactory
for holding it in place. For steep slopes and special situations where greater control is needed, erosion
control blankets anchored with stakes should be used instead of mulch.
Hydraulic mulching consists of wood cellulose fibers mixed with water and a tackifying agent and should
be applied at a rate of no less than 1,500 pounds per acre (1,425 lbs of fibers mixed with at least 75 lbs of
tackifier) with a hydraulic mulcher. For steeper slopes, up to 2000 pounds per acre may be required for
effective hydroseeding. Hydromulch typically requires up to 24 hours to dry; therefore, it should not be
applied immediately prior to inclement weather. Application to roads, waterways and existing vegetation
should be avoided.
Erosion control mats, blankets, or nets are recommended to help stabilize steep slopes (generally 3:1 and
steeper) and waterways. Depending on the product, these may be used alone or in conjunction with grass
or straw mulch. Normally, use of these products will be restricted to relatively small areas.
Biodegradable mats made of straw and jute, straw-coconut, coconut fiber, or excelsior can be used instead
of mulch. (See the ECM/TRM BMP for more information.)
Some tackifiers or binders may be used to anchor mulch. Check with the local jurisdiction for allowed
tackifiers. Manufacturer's recommendations should be followed at all times. (See the Soil Binder BMP
for more information on general types of tackifiers.)
Rock can also be used as mulch. It provides protection of exposed soils to wind and water erosion and
allows infiltration of precipitation. An aggregate base course can be spread on disturbed areas for
temporary or permanent stabilization. The rock mulch layer should be thick enough to provide full
coverage of exposed soil on the area it is applied.
Maintenance and Removal
After mulching, the bare ground surface should not be more than 10 percent exposed. Reapply mulch, as
needed, to cover bare areas.

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.

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.

Mulch
Cover seeded areas with mulch or an appropriate rolled erosion control product to promote establishment

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.
Surface Roughening (SR) EC-1
November 2010 Urban Drainage and Flood Control District SR-1
Urban Storm Drainage Criteria Manual Volume 3
Photograph SR-1. Surface roughening via imprinting for temporary
stabilization.
Description
Surface roughening is an erosion control
practice that involves tracking,
scarifying, imprinting, or tilling a
disturbed area to provide temporary
stabilization of disturbed areas. Surface
roughening creates variations in the soil
surface that help to minimize wind and
water erosion. Depending on the
technique used, surface roughening may
also help establish conditions favorable
to establishment of vegetation.
Appropriate Uses
Surface roughening can be used to
provide temporary stabilization of
disturbed areas, such as when
revegetation cannot be immediately established due to seasonal planting limitations. Surface roughening
is not a stand-alone BMP, and should be used in conjunction with other erosion and sediment controls.
Surface roughening is often implemented in conjunction with grading and is typically performed using
heavy construction equipment to track the surface. Be aware that tracking with heavy equipment will also
compact soils, which is not desirable in areas that will be revegetated. Scarifying, tilling, or ripping are
better surface roughening techniques in locations where revegetation is planned. Roughening is not
effective in very sandy soils and cannot be effectively performed in rocky soil.
Design and Installation
Typical design details for surfacing roughening on steep and mild slopes are provided in Details SR-1 and
SR-2, respectively.
Surface roughening should be performed either after final grading or to temporarily stabilize an area
during active construction that may be inactive for a short time period. Surface roughening should create
depressions 2 to 6 inches deep and approximately 6 inches apart. The surface of exposed soil can be
roughened by a number of techniques and equipment. Horizontal grooves (running parallel to the
contours of the land) can be made using tracks from equipment treads, stair-step grading, ripping, or
tilling.
Fill slopes can be constructed with a roughened surface. Cut slopes that have been smooth graded can be
roughened as a subsequent operation. Roughening should follow along the contours of the slope. The
tracks left by truck mounted equipment working perpendicular
to the contour can leave acceptable horizontal depressions;
however, the equipment will also compact the soil.

Maintenance and Removal
Care should be taken not to drive vehicles or equipment over areas that have been surface roughened.
Tire tracks will smooth the roughened surface and may cause runoff to collect into rills and gullies.
Because surface roughening is only a temporary control, additional treatments may be necessary to
maintain the soil surface in a roughened condition.
Areas should be inspected for signs of erosion. Surface roughening is a temporary measure, and will not
provide long-term erosion control.

1. THIS EROSION CONTROL PLAN AND ASSOCIATED SWMP ARE LIVING DOCUMENTS REQUIRING PERIODIC
REVIEW AND UPDATING AS SITE CONDITIONS CHANGE OR AS REQUIRED BY LOCAL AUTHORITIES. IT IS
THE CONTRACTOR'S RESPONSIBILITY TO ENSURE ONGOING COMPLIANCE WITH THE REQUIREMENTS
OF THE STORMWATER DISCHARGE PERMIT.
2. THE SIZE, TYPE AND LOCATION OF ALL KNOWN UNDERGROUND UTILITIES ARE APPROXIMATE WHEN
SHOWN ON THESE DRAWINGS. IT SHALL BE THE RESPONSIBILITY OF THE CONTRACTOR TO VERIFY
THE EXISTENCE OF ALL UNDERGROUND UTILITIES IN THE AREA OF THE WORK. BEFORE COMMENCING
NEW CONSTRUCTION, THE CONTRACTOR SHALL BE RESPONSIBLE FOR LOCATING ALL UNDERGROUND
UTILITIES AND SHALL BE RESPONSIBLE FOR ALL UNKNOWN UNDERGROUND UTILITIES.
3. EROSION CONTROL PRACTICES, SITE PROTECTION AND REVEGETATION METHODS SHALL FOLLOW
CITY OF FORT COLLINS REGULATIONS.
4. DURING CONSTRUCTION PHASING, INSTALL EROSION CONTROL MEASURES FOLLOWING BMPS WITH
EACH PHASE, AS REQUIRED.
5. PERIMETER PROTECTION (I.E., STRAW WATTLES) IS SHOWN AROUND EACH BLOCK THAT IS A PART OF
THE PROPOSED IMPROVEMENTS. REFER TO THE LEGEND (SEE RIGHT). THIS PERIMETER PROTECTION
SHALL BE INSTALLED WHEN CURB, GUTTER AND SIDEWALK INSTALLATION IS COMPLETED IN THE
ADJOINING RIGHT-OF-WAY. THE CONTRACTOR IS RESPONSIBLE FOR REPLACING PERIMETER
PROTECTION (i.e., STRAW WATTLES) DAMAGED BY CONSTRUCTION TRAFFIC (e.g., TRUCKS DRIVING
OVER STRAW WATTLES AND FLATTENING THEM).
6. FOLLOWING OVERLOT GRADING OR ANY OTHER LAND DISTURBING ACTIVITY, ALL OTHER AREAS OF
THE SITE TO BE DEVELOPED DURING LATER PHASES OF CONSTRUCTION AND WHICH SHALL REMAIN
EXPOSED FOR MORE THAN THIRTY-(30) DAYS WILL REQUIRE TEMPORARY OR PERMANENT EROSION
CONTROL (I.E., SEED/MULCH, LANDSCAPING, ETC.).
7. SEE LANDSCAPE PLANS FOR ADDITIONAL INFORMATION ON SEEDING/PLANTING, REVEGETATION,
EROSION FABRIC/BLANKETS, IRRIGATION, HARDSCAPE AND OTHER TEMPORARY AND PERMANENT
SITE STABILIZATION METHODS.
8. SEE EROSION CONTROL NOTES ON THIS SHEET AND GRADING & EROSION CONTROL NOTES ON SHEET
CV02, AS WELL AS DETAILS ON SHEETS DT09-DT11.
9. ANY TRACKING OF MUD OR DEBRIS ONTO ADJACENT STREETS BY THE CONTRACTOR(S) SHALL BE
IMMEDIATELY REMEDIED AND SWEPT.

Survey Area Data: Version 9, Sep 22, 2014
Soil map units are labeled (as space allows) for map scales 1:50,000
or larger.
Date(s) aerial images were photographed: Apr 22, 2011—Apr 28,
2011
The orthophoto or other base map on which the soil lines were
compiled and digitized probably differs from the background
imagery displayed on these maps. As a result, some minor shifting
of map unit boundaries may be evident.
