CONFIDENTIALITY
IN CONNECTION WITH THE SERVICES to be provided by Service Provider under this
Agreement, the parties agree to comply with reasonable policies and procedures with regard to
the exchange and handling of confidential information and other sensitive materials between the
parties, as set forth below.
1. Definitions.
For purposes of this Agreement, the party who owns the confidential information and is
disclosing same shall be referenced as the “Disclosing Party.” The party receiving the
Disclosing Party’s confidential information shall be referenced as the “Receiving Party.”
2. Confidential Information.
Confidential Information controlled by this Agreement refers to information which is not public
and/or is proprietary and includes by way of example, but without limitation, City customer
information, utility data, service billing records, customer equipment information, location
information, network security system, business plans, formulae, processes, intellectual
property, trade secrets, designs, photographs, plans, drawings, schematics, methods,
specifications, samples, reports, mechanical and electronic design drawings, customer lists,
financial information, studies, findings, inventions, and ideas.
To the extent practical, Confidential Information shall be marked “Confidential” or
“Proprietary.” Nevertheless, Service Provider shall treat as Confidential Information all
customer identifiable information in any form, whether or not bearing a mark of confidentiality
or otherwise requested by the City, including but not limited to account, address, billing,
consumption, contact and other customer data. In the case of disclosure in non-documentary
form of non-customer identifiable information, made orally or by visual inspection, the
Disclosing Party shall have the right, or, if requested by the Receiving Party, the obligation to
confirm in writing the fact and general nature of each disclosure within a reasonable time after
it is made in order that it is treated as Confidential Information. Any information disclosed to
the other party prior to the execution of this Agreement and related to the services for which
Service Provider has been engaged shall be considered in the same manner and be subject
to the same treatment as the information disclosed after the execution of this Agreement with
regard to protecting it as Confidential Information.
3. Use of Confidential Information.
Receiving Party hereby agrees that it shall use the Confidential Information solely for the
purpose of performing its obligations under this Agreement and not in any way detrimental to
Disclosing Party. Receiving Party agrees to use the same degree of care Receiving Party
uses with respect to its own proprietary or confidential information, which in any event shall
result in a reasonable standard of care to prevent unauthorized use or disclosure of the
Confidential Information. Except as otherwise provided herein, Receiving Party shall keep
confidential and not disclose the Confidential Information. The City and Service Provider shall
cause each of their directors, officers, employees, agents, representatives, and
subcontractors to become familiar with, and abide by, the terms of this section, which shall
survive this Agreement as an on-going obligation of the Parties.
Service Provider shall not use such information to obtain any economic or other benefit for
itself, or any third party, other than in the performance of obligations under this Agreement.
BID 9716 Utilities Miscellaneous Concrete Work Page 36 of 175
4. Exclusions from Definition.
The term “Confidential Information” as used herein does not include any data or information
which is already known to the Receiving Party or which before being divulged by the
Disclosing Party (1) was generally known to the public through no wrongful act of the
Receiving Party; (2) has been rightfully received by the Receiving Party from a third party
without restriction on disclosure and without, to the knowledge of the Receiving Party, a
breach of an obligation of confidentiality; (3) has been approved for release by a written
authorization by the other party hereto; or (4) has been disclosed pursuant to a requirement
of a governmental agency or by operation of law.
5. Required Disclosure.
If the Receiving Party is required (by interrogatories, requests for information or documents,
subpoena, civil investigative demand or similar process, or by federal, state, or local law,
including without limitation, the Colorado Open Records Act) to disclose any Confidential
Information, the Parties agree the Receiving Party will provide the Disclosing Party with
prompt notice of such request, so the Disclosing Party may seek an appropriate protective
order or waive the Receiving Party’s compliance with this Agreement.
The Receiving Party shall furnish a copy of this Agreement with any disclosure.
6. Notwithstanding paragraph 5, Service Provider shall not disclose Confidential Information to
any person, directly or indirectly, nor use it in any way, except as required or authorized in
writing by the City.
7. Red Flags Rules.
Service Provider must implement reasonable policies and procedures to detect, prevent and
mitigate the risk of identity theft in compliance with the Identity Theft Red Flags Rules found
at 16 Code of Federal Regulations part 681. Further, Service Provider must take appropriate
steps to mitigate identity theft if it occurs with one or more of the City’s covered accounts and
must as expeditiously as possible notify the City in writing of significant breeches of security
or Red Flags to the City.
8. Data Protection and Data Security.
In addition to the requirements of paragraph 7, Service Provider shall have in place
information security safeguards designed to conform to or exceed industry best practices
regarding the protection of the confidentiality, integrity and availability of utility and customer
information and shall have written agreements requiring any subcontractor to meet those
standards. These information security safeguards (the “Information Security Program”) shall
be materially consistent with, or more stringent than, the safeguards described in this Exhibit.
a) Service Provider’s information security safeguards shall address the following elements:
• Data Storage, Backups and Disposal
• Logical Access Control (e.g., Role-Based)
• Information Classification and Handling
• Secure Data Transfer (SFTP and Data Transfer Specification)
• Secure Web Communications
• Network and Security Monitoring
• Application Development Security
BID 9716 Utilities Miscellaneous Concrete Work Page 37 of 175
• Application Security Controls and Procedures (User Authentication, Security
Controls, and Security Procedures, Policies and Logging)
• Incident Response
• Vulnerability Assessments
• Hosted Services
• Personnel Security
b) Subcontractors. Service Provider may use subcontractors, though such activity shall not
release or absolve Service Provider from the obligation to satisfy all conditions of this
Agreement, including the data security measures described in this Exhibit, and to require
a substantially similar level of data security, appropriate to the types of services provided
and Customer Data received, for any subcontractor Service Provider may use.
Accordingly, any release of data, confidential information, or failure to protect information
under this Agreement by a subcontractor or affiliated party shall be attributed to Service
Provider and may be considered to be a material breach of this Agreement.
9. Confidential Information is not to be stored on any local workstation, laptop, or media such as
CD/DVD, USB drives, external hard drives or other similar portable devices unless the Service
Provider can ensure security for the Confidential Information so stored. Work stations or
laptops to be used in the Work will be required to have personal firewalls on each, as well as
have current, active anti-virus definitions.
10. The Agreement not to disclose Confidential Information as set forth in this Exhibit shall apply
during the term of the Work and at any time thereafter unless specifically authorized by the
City in writing.
11. If Service Provider breaches this Agreement, in the City’s sole discretion, the City may
immediately terminate this Agreement and withdraw Service Provider’s right to access
Confidential Information.
12. Notwithstanding any other provision of this Agreement, all material, i.e., various physical forms
of media in which Confidential Information is contained, including but not limited to writings,
drawings, tapes, diskettes, prototypes or products, shall remain the sole property of the
Disclosing Party and, upon request, shall be promptly returned, together with all copies thereof
to the Disclosing Party. Upon such return of physical records, all digital and electronic data
shall also be deleted in a non-restorable way by which it is no longer available to the Receiving
Party. Written verification of the deletion (including date of deletion) is to be provided to the
Disclosing Party within ten (10) days after completion of engagement, whether it be via
termination, completion or otherwise.
13. Service Provider acknowledges that the City may, based upon the representations made in
this Agreement, disclose security information that is critical to the continued success of the
City’s business. Accordingly, Service Provider agrees that the City does not have an adequate
remedy at law for breach of this Agreement and therefore, the City shall be entitled, as a non-
exclusive remedy, and in addition to an action for damages, to seek and obtain an injunction
or decree of specific performance or any other remedy, from a court of competent jurisdiction
to enjoin or remedy any violation of this Agreement.

Section 104 -SCOPE OF WORK - is hereby revised as follows:
Subsection 104.04 –Maintaining Traffic - is revised to include the following.
It shall be the Contractor's responsibility to clear parking from the streets when such parking will interfere with
the work. Prior to work that requires the street(s) to be closed to parking and/or traffic, the street(s) shall be
posted for "NO PARKING". “NO PARKING” signs shall be placed at a minimum of 100-foot intervals. The
placement of these signs shall take place at least 24 hours prior to the commencement of work and shall clearly
show the type of work, and the day, date, and times that the message on the sign is in effect. (For example, if a
street is to be repaired on Wednesday, July 2, the street shall be posted no later than Tuesday, July 1, by 7:00
a.m. with a sign that reads similar to "NO PARKING, WEDNESDAY, JULY 2, 7:00 A.M. TO 6:00 P.M.,

until the street is opened to traffic and all clean-up operations completed. No Parking signs shall only be placed,
maintained and removed by a representative of the Contractor, the Traffic Control Supervisor, or Flagger. The
contractor shall not have “No Parking” signs up and posted where work is not anticipated. Signs that have been
posted where work will not commence as posted shall be turned away from traffic.
All information on the "NO PARKING" signs, with the exception of the type of work, date, and time shall be in
block letters permanently affixed to the sign. Any information added to a sign, such as dates, shall be clearly
legible and written in block style letters. The “NO PARKING” signs shall be in effect for the duration of the
project.
In the event the Contractor deems it necessary to remove a vehicle that has not adhered to the “NO PARKING”
notification, the Contractor shall first make every reasonable effort to locate and contact the owner of the
vehicle. Should the Contractor be unable to locate the owner of the vehicle, the Contractor shall notify the
Engineer/Project Manager to arrange for towing. If the “NO PARKING’ sign has been in place for a minimum
of 24 hours, the City will make every reasonable effort to remove the offending vehicle within four (4) hours of
notification from the Contractor. The Contractor shall not be entitled to additional compensation for delays
associated with the towing of illegally parked vehicles.
The Contractor shall always have an approved Traffic Control Plan on site. Traffic control signage on the
construction site shall be set up in accordance with the approved traffic control plan and in accordance with the
specifications.
Work performed by the Contractor without an approved traffic control plan or when “NO PARKING” signs
have not been placed as required by the specifications shall not be paid.
The Contractor shall also be subject to a pay deduction of up to $1,000.00 per occurrence per day for traffic
control not in compliance with referenced specifications or requirements contained herein. Issues subject to
deductions may include but are not limited to:
Traffic Control Supervisor not on the project site always (unless pre-approved by the Engineer/Project
Manager)
An approved traffic control plan not on site
Traffic control device set up by flagging personnel unless assisting the Traffic Control Supervisor
Traffic control signage not set up in accordance with the approved traffic control plans
Inadequate flagging personnel and/or flagging equipment
The Engineer/Project Manager shall issue a written warning to the Contractor, Subcontractor, and/or Traffic
Control Supervisor documenting the type of violation. The Engineer/Project Manager shall determine the
deduction amount based on the Engineer/Project Manager s’ opinion of the infraction severity and the number
of previous infractions. Upon issuance of a third violation, the Engineer/Project Manager may request the
Subcontractor, Traffic Control Supervisor and/or flagging personnel be removed from the project. Removal
from the project in which the violations were issued shall be in effect for the remainder of the contract. The
contractor shall find replacement Traffic Control Subcontractor, TCS, and/or flagging personnel within two
weeks of the third notice without an adjustment to contract price or working days or the Contract may be
terminated and rebid.
BID 9716 Utilities Miscellaneous Concrete Work Page 41 of 175
Prior to the end of each work shift the approved Traffic Control Supervisor (TCS), and the Engineer/Project
Manager shall meet to discuss the placement of upcoming traffic control devices to include "NO PARKING"
signs. The quantity of traffic control devices used that day and for the next day shall be agreed upon by the
Contractor and the Engineer/Project Manager. Any necessary adjustments shall be made. The Contractor and
Engineer/Project Manager shall also review and determine the proposed means of handling parking and traffic
control for the upcoming work.
It is the responsibility of the Contractor to minimize any inconvenience to the public as a result of their work.
The Contractor shall always maintain access to all businesses within the project. The installation schedule shall
be communicated to all businesses and residents affected by the work at least 48 hours prior to starting work.

Section 105 – CONTROL OF WORK - is hereby revised as follows:
Subsection 105.01 - Authority of the Engineer/Project Manager - is revised to include the following:
No phase of construction shall start until the Traffic Control Plan has been approved. Failure to have an
approved Traffic Control Plan shall constitute cause for the Owner to stop work.
During periods of Traffic Control non-compliance, the work will be stopped and the Contractor may be assessed
$1,000.00 per day, may forfeit payment of work and materials installed, and may lose contract working days as
determined by the Engineer/Project Manager. The Contractor shall not be entitled to compensation for delays
associated with non-compliant periods.
No construction shall commence until all utilities are located within the construction area per state law. The
Contractor is responsible for identifying all utilities of concern and calling for appropriate locates. After
contacting 811 to get locates, the contractor may be required to call for clarification and/or additional locates or
may be required to contact a City of Fort Collins department associated with certain types of utilities. Due to the
high demand of locate companies during the construction season, the City of Fort Collins recommends that the
Contractor schedules a locate company at least one week in advance to minimize any possible delays. If the
locate marks become expired, then contractor shall get an extension and request that the markings are redone
and freshened up. If the Contractor does not have locates on a project scheduled to start work that day, the work
shall be “stopped”, and the Contractor shall be charged working days until that said marking is completed, and
work has commenced.
Subsection 105.02 - Plans, Shop Drawings, Working Drawings, Other Submittals, and Construction Drawings
- is revised to include the following:
The Contractor shall furnish the required submittals in TABLE 105-1 one week before the commencement of
work. Three (3) copies shall be furnished to the Engineer/Project Manager, two (2) copies will be returned to
the Contractor upon approval. Submittals shall not be measured and paid for separately but shall be considered
incidental to the work.

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
Photograph SF-1. Silt fence creates a sediment barrier, forcing
sheet flow runoff to evaporate or infiltrate.
Silt fence should be installed along the contour of slopes so that it intercepts sheet flow. The maximum
recommended tributary drainage area per 100 lineal feet of silt fence, installed along the contour, is
approximately 0.25 acres with a disturbed slope length of up to 150 feet and a tributary slope gradient no
steeper than 3:1. Longer and steeper slopes require additional measures. This recommendation only
applies to silt fence installed along the contour. Silt fence installed for other uses, such as perimeter
control, should be installed in a way that will not produce concentrated flows. For example, a "J-hook"
installation may be appropriate to force runoff to pond and evaporate or infiltrate in multiple areas rather
than concentrate and cause erosive conditions parallel to the silt fence.
See Detail SF-1 for proper silt fence installation, which involves proper trenching, staking, securing the
fabric to the stakes, and backfilling the silt fence. Properly installed silt fence should not be easily pulled
out by hand and there should be no gaps between the ground and the fabric.
Silt fence must meet the minimum allowable strength requirements, depth of installation requirement, and
other specifications in the design details. Improper installation
of silt fence is a common reason for silt fence failure; however,
when properly installed and used for the appropriate purposes, it
can be highly effective.

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

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

Description
A sediment control log is a linear roll
made of natural materials such as
straw, coconut fiber, or compost. The
most common type of sediment control
log has straw filling and is often
referred to as a "straw wattle." All
sediment control logs are used as a
sediment barrier to intercept sheet flow
runoff from disturbed areas.
Appropriate Uses
Sediment control logs can be used in
the following applications to trap
sediment:
As perimeter control for stockpiles
and the site.
As part of inlet protection designs.
As check dams in small drainage
ditches. (Sediment control logs
are not intended for use in
channels with high flow
velocities.)
On disturbed slopes to shorten flow
lengths (as an erosion control).
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.
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.

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

Description
A straw bale barrier is a linear wall of
straw bales designed to intercept sheet
flow and trap sediment before runoff exits
a disturbed area.
Appropriate Uses
Appropriate uses of properly installed
straw bale barriers may include:
As a perimeter control for a site or soil
stockpile.
As a sediment control at the toe of an
erodible slope.
Along the edge of a stream or drainage
Photograph SBB-1. Straw bale barrier used for perimeter control.

pathway to reduce sediment laden runoff from entering the waterway.
As part of an inlet protection design in sump conditions (See Inlet Protection BMP).
Do not use straw bale barriers in areas of concentrated flow or in areas where ponding is not desirable.
Straw bales tend to degrade quickly, so they should generally not be used in areas where longer term
disturbance is expected.
Due to a history of inappropriate placement, poor installation, and short effective lifespan, the use of
straw bales is discouraged or prohibited by some communities.
Design and Installation
The maximum recommended tributary drainage area per 100 lineal feet of straw bale barrier is 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. Design details with notes are provided in Detail SBB-1.
To be effective, bales must be installed in accordance with the design details with proper trenching,
staking, and binding. Jute and cotton string must not be used to bind the straw bale. The bales should be
certified weed-free prior to use.
Maintenance and Removal
Check bales for rotting and replace as necessary. Straw bales degrade, and rotting bales require
replacement on a regular basis (as often as every three months) depending on environmental conditions.
Check for undercutting, bypassed flows, and displacement.
Repair by properly re-installing the straw bale barrier and
repairing washouts around the bales. Remove sediment
accumulated behind the bale when it reaches one-quarter of
the bale height. Remove and properly dispose of the straw
bale once the upstream area has been stabilized. Areas of
disturbance beneath the bale should be seeded and mulched
when the bale is removed.

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
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.
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.

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.

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.

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.
IP-2 Urban Drainage and Flood Control District

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.

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.

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

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

erosion and providing favorable conditions for revegetation.
Description
Rolled Erosion Control Products
(RECPs) include a variety of
temporary or permanently installed
manufactured products designed to
control erosion and enhance vegetation
establishment and survivability,
particularly on slopes and in channels.
For applications where natural
vegetation alone will provide sufficient
permanent erosion protection,
temporary products such as netting,
open weave textiles and a variety of
erosion control blankets (ECBs) made
of biodegradable natural materials
(e.g., straw, coconut fiber) can be used.
For applications where natural
vegetation alone will not be sustainable under expected flow conditions, permanent rolled erosion control
products such as turf reinforcement mats (TRMs) can be used. In particular, turf reinforcement mats are
designed for discharges that exert velocities and sheer stresses that exceed the typical limits of mature
natural vegetation.
Appropriate Uses
RECPs can be used to control erosion in conjunction with revegetation efforts, providing seedbed
protection from wind and water erosion. These products are often used on disturbed areas on steep
slopes, in areas with highly erosive soils, or as part of drainageway stabilization. In order to select the
appropriate RECP for site conditions, it is important to have a general understanding of the general types
of these products, their expected longevity, and general characteristics.
The Erosion Control Technology Council (ECTC 2005) characterizes rolled erosion control products
according to these categories:
Mulch control netting: A planar woven natural fiber or extruded geosynthetic mesh used as a
temporary degradable rolled erosion control product to anchor loose fiber mulches.
Open weave textile: A temporary degradable rolled erosion control product composed of processed
natural or polymer yarns woven into a matrix, used to provide erosion control and facilitate
vegetation establishment.
Erosion control blanket (ECB): A temporary
degradable rolled erosion control product composed of
processed natural or polymer fibers which are
mechanically, structurally or chemically bound together
to form a continuous matrix to provide erosion control
and facilitate vegetation establishment. ECBs can be
further differentiated into rapidly degrading single-net
and double-net types or slowly degrading types.

Turf Reinforcement Mat (TRM): A rolled erosion control product composed of non-degradable
synthetic fibers, filaments, nets, wire mesh, and/or other elements, processed into a permanent, three-
dimensional matrix of sufficient thickness. TRMs, which may be supplemented with degradable
components, are designed to impart immediate erosion protection, enhance vegetation establishment
and provide long-term functionality by permanently reinforcing vegetation during and after
maturation. Note: TRMs are typically used in hydraulic applications, such as high flow ditches and
channels, steep slopes, stream banks, and shorelines, where erosive forces may exceed the limits of
natural, unreinforced vegetation or in areas where limited vegetation establishment is anticipated.
Tables RECP-1 and RECP-2 provide guidelines for selecting rolled erosion control products appropriate
to site conditions and desired longevity. Table RECP-1 is for conditions where natural vegetation alone
will provide permanent erosion control, whereas Table RECP-2 is for conditions where vegetation alone
will not be adequately stable to provide long-term erosion protection due to flow or other conditions.

Design and Installation
RECPs should be installed according to manufacturer’s specifications and guidelines. Regardless of the
type of product used, it is important to ensure no gaps or voids exist under the material and that all
corners of the material are secured using stakes and trenching. Continuous contact between the product
and the soil is necessary to avoid failure. Never use metal stakes to secure temporary erosion control
products. Often wooden stakes are used to anchor RECPs; however, wood stakes may present installation
and maintenance challenges and generally take a long time to biodegrade. Some local jurisdictions have
had favorable experiences using biodegradable stakes.
This BMP Fact Sheet provides design details for several commonly used ECB applications, including:
ECB-1 Pipe Outlet to Drainageway
ECB-2 Small Ditch or Drainageway
ECB-3 Outside of Drainageway
BID 9716 Utilities Miscellaneous Concrete Work Page 131 of 175
Staking patterns are also provided in the design details according to these factors:
ECB type
Slope or channel type
For other types of RECPs including TRMs, these design details are intended to serve as general
guidelines for design and installation; however, engineers should adhere to manufacturer’s installation
recommendations.
Maintenance and Removal
Inspection of erosion control blankets and other RECPs includes:
Check for general signs of erosion, including voids beneath the mat. If voids are apparent, fill the
void with suitable soil and replace the erosion control blanket, following the appropriate staking
pattern.
Check for damaged or loose stakes and secure loose portions of the blanket.
Erosion control blankets and other RECPs that are biodegradable typically do not need to be removed
after construction. If they must be removed, then an alternate soil stabilization method should be installed
promptly following removal.
Turf reinforcement mats, although generally resistant to biodegradation, are typically left in place as a
dense vegetated cover grows in through the mat matrix. The turf reinforcement mat provides long-term
stability and helps the established vegetation resist erosive forces.
