Introduction
The purpose of these policies and procedures is to set the basic principles and standards to be observed by all entities and person(s) who perform work in the public right-of-way in the City of Fort Collins, Colorado. All those working in the public right-of-way are to provide a safe and effective work area, to warn, control, protect, and expedite vehicular, cyclist and pedestrian traffic.
Applicability
The requirements specified in these policies and procedures are applicable for all entities and persons where traffic is affected by such work in the public right-of-way, e.g., contractors, public utilities, and all city work crews.
Goals
Properly executed traffic control techniques will have the following results:
- Conformity with national, state, city and the Manual on Uniform Traffic Control Devices (MUTCD) regulations for traffic control.
- Safety for work crews, motorists, cyclists, pedestrians, and the community.
- Safety in work areas; to warn, control, protect, and expedite vehicular, cycling, and pedestrian traffic.
- Safe access for police, fire, and rescue vehicles.
- Prevent damage to private and public property, e.g., damage to construction projects, construction equipment, sidewalks, vehicles, sprinkler systems, etc.
- Minimize the possibility of claims and litigation from construction area accidents.
- Reduce confusion to motorists, cyclists, and pedestrians.
- Improve public communication.
Definitions for Work Area Traffic Control Terminology
Emergency Closure
Defined as an unforeseen combination of circumstances or the resulting state that calls for immediate action.
These are the only situations in which a Work Area Traffic Control (WATC) Plan will be given a verbal confirmation for work to start with a post-dated WATC Plan Approval Form submitted later in the day. Under no other circumstances besides a true emergency will a verbal confirmation for work approval ever be given.
Jurisdiction
Defined as the public right-of-way within the City of Fort Collins. The City Traffic Engineer and designees have authority for reviewing and prescribing proper traffic control and will have final determination in case of conflict including traffic control devices at a work zone. The Traffic Operations Department has the responsibility to assure public safety within the City of Fort Collins public right-of-way.
All work performed in the jurisdiction requires a permit from the City of Fort Collins Traffic Operations Department. This includes all work where traffic moves differently than the normal conditions of the public right-of-way through traffic way or area. All permit requests will be submitted to the City of Fort Collins Traffic Operations Department for approval prior to starting any project within the jurisdiction. Commencement of work may then begin per conditions set by the permit.
Permitting
Defined as receiving approval of submitted WATC Plan from the City of Fort Collins Traffic Engineer.
Public Right-of-Way
Defined as the space, including the sidewalk(s) and roadway(s) the public uses within the City of Fort Collins.
Sign Types
See sign types outlined below.
Special Event Permit and Neighborhood Block Parties
Please see the Special Event Permit and Block Parties web pages.
Traffic
Defined as vehicular, cycling, or pedestrian movement.
Traffic Control Devices
Defined as a sign, signal, marking, or other device used to regulate, warn, or guide traffic, placed on, over, or adjacent roadway or shared use path, e.g., bike and pedestrian trails.
Traffic Control Plan (TCP or TC)
A diagram(s) of the plan to work within the public right-of-way efficiently and effectively while maintaining a safe, uniform, flow of traffic for construction work and the public traveling through the work zone in vehicles, cyclists or pedestrians.
Work Area Traffic Control (WATC) Plan
The combination of the approval form and the TCP, also referred to as the permit.
Work Area Traffic Control Zone or Work Zone
Defined as the stretch or portion of roadway within the public right-of-way in which all the traffic control device(s) (e.g., signs, flashing lights, channelizing devices, barriers, pavement markings, flagmen, warning signs, and arrow boards mounted, etc.) are used to warn, regulate, or guide motorists, cyclists, and pedestrians through construction, maintenance, or utility operations. These traffic control devices also mark the beginning and end of construction and/or maintenance or utility work areas (zones). It extends from the first warning sign, signal, or flashing lights to the “END ROAD WORK” sign or the last traffic control device pertinent to that work zone.
Work zones also include roadway sections where there is ongoing, moving (mobile) work activity such as lane line painting or roadside mowing only if the beginning of the ongoing, moving (mobile) work activity is designated by warning signs or signals.
The responsibility for the installation and maintenance of work zones rests with the person(s) or entity, e.g., contractor, utility company, or public agency, doing the work. All work area traffic control setups and devices will conform to the national, state, and city standards and the MUTCD. All questions related to traffic control are to be addressed to the City of Fort Collins Traffic Operations Department.
Planning & Execution
The entity or person(s) intending to do major work in the public right-of-way will contact the City of Fort Collins Traffic Operations Department, as well as all impacted departments at the start of the planning process, allowing time for meetings, revisions and submittal timelines. All persons responsible for supervising work zones and work sites will plan in advance to keep traffic obstructions, public inconvenience and lost work time to a minimum.
Contacts
Contact and coordinate with all relevant City of Fort Collins Departments who will be involved in the project. It’s important to remember these contacts must be included at the beginning stages of planning as well as throughout the process.
Plans
Rules and Guidelines for TCPs:
- Traffic lanes may be narrowed to no less than ten (10) feet in width.
- Traffic may be moved over into part of the shoulder, providing that portion is safely drivable to motorists, cyclists and pedestrians.
- The number of lanes may be reduced at certain locations as determined by the Traffic Operations Department – contact the department for specifics.
- Traffic may be detoured over another traffic way, provided it does not interfere with another project within the area.
- All open holes (e.g., sidewalk removal, utility trenches, tie-ins, bore pits, etc.) left overnight must be illuminated and surrounded with the proper safety devices. It is preferred that open holes be backfilled at the end of approved working hours.
Time of Work
- No work will be scheduled on arterial streets and sidewalks during peak traffic hours without written authorization from the City Traffic Engineer or designees.
- Construction or repair work is not permitted at or near signalized intersections or on arterial/collector streets during 7-8:30 a.m. or 3:30-6:30 p.m., except for emergencies or if noted on the WATC form.
- No work on holidays except in emergencies.
- No full street closures unless specially approved.
- Arterial roadway work should be scheduled for weekends or nights.
Considerations to include in your plans:
- American Disability Act
- Cyclists and pedestrians affected by the work zone
- Traffic conditions
- Traffic lane requirements
- Sight distances
- Schedule and expedite work to minimize public inconvenience
- Provide advanced warning to regulate speed
- Ensure guidance pattern provides safe, even traffic flow
- Reduce driver decision-making complexity
- Check the zone regularly to ensure devices are in place and operating
- Install and maintain traffic control devices, including type, number, and placement of signs
- Coordinate with existing traffic control/signage
- Remove traffic control devices promptly when no longer needed
- Provide safeguards for workers and public (e.g., knowledgeable flaggers, PPE for all on-site personnel)
- Be aware of other nearby work zone areas
Obtain All Applicable Permits
- Identify necessary permits by contacting the departments listed earlier.
Excavating Permits
- A written permit is required from the City Engineer (970-221-6605) for work affecting streets, alleys, sidewalks, and/or right-of-way, per Chapter 23 of the City Code.
- Minimum five workdays required for approval.
- City departments must still submit a TCP for review/approval, even if no excavation permit is needed.
Notification and Public Information
Notify all impacted entities or individuals as listed under Contacts, and coordinate with other ongoing projects. Include the following additional contacts as directed:
- Fort Collins Coloradoan and local radio stations (typically notified Friday mornings by the City for approved TCPs)
Notify nearby property occupants by mail or door-to-door flyer at least 24 hours in advance. Send copies to FCWATC@fortcollins.gov.
Notifications must include:
- Name of entity/person(s) doing the work
- Start and end times/dates
- Work location
- Any detours, access changes, or business/residential access adjustments
- Contact info for issues or concerns
Public communication helps reduce congestion and improve work zone functionality. The City uses WATC application details to update FCTrip. Additional outreach may be coordinated in meetings with Traffic Operations staff.
Temporary Traffic Control Zone Devices
Properly planned traffic control devices, when uniformly placed and well-maintained, are the most effective system of warning and guidance. All devices must meet or exceed the latest MUTCD requirements. In some cases, the City of Fort Collins Traffic Operations Department may request higher standards than MUTCD minimums.
Signs
Placement
- Overnight signs must be reflectorized and/or illuminated. Signs not needed overnight should not remain in the roadway (including bike lanes or sidewalks) unless approved by the Traffic Operations Department.
- Signs may not be turned backward and left in place.
- Acceptable overnight signs include total road closures, partial closures, drive lane closures, or emergency closures.
- Center medians: Two 48” x 48” signs are required on either side of the roadway when a divided center median is present.
- Raised center median islands are the only acceptable locations for double-posted signs, unless otherwise approved.
- Sign face and visibility: Signs should face oncoming traffic and have a minimum height of 2 feet from the bottom of the sign to the roadway. Adjust placement when sight lines are not straight.
- Installation: Signs must be installed immediately before work begins and removed when no longer needed. Pre-project signs may be installed ahead of time for early warning.
Sign Types
Advanced Warning Area
Marks the beginning of the traffic control zone. Device placement depends on conditions such as driveways, side streets, site obstructions, and parked vehicles.
Distance Signs
Signs such as “ROAD WORK AHEAD 1000 FEET” are not used within city limits. Instead, use “ROAD WORK AHEAD” unless prior approval is obtained.
“END ROAD WORK” Signs
Should be placed at the end of the termination area. Coordinate placement with the Traffic Operations Department if located on city right-of-way.
Pre-warning Signs
- Must not be placed in bike lanes, sidewalks, or driveways.
- Exceptions for sidewalk placement must be approved by Traffic Operations.
- The only acceptable bike lane sign is “BIKE LANE ENDS MERGE WITH TRAFFIC” (30” x 24”, black text on orange, 4” letters).
Regulatory Sign Usage
Must be approved by the Traffic Operations Department. Contractors/permittees are responsible for installing, maintaining, and if needed, replacing existing regulatory signs in or near the work zone. No signs may be removed without consent. Notify the department 48 hours in advance if signs will be changed or relocated.
Specialty Signs
May be required for long-duration projects or significant traffic impacts (major roads, intersections, sidewalks, bike lanes). Contact Traffic Operations before producing specialty signs.
Temporary “No Parking” Signs
- Must be 12” x 18” red-on-white with restricted times and dates clearly listed.
- Property owners and businesses must be notified at least 24 hours in advance.
Traffic Control Zone Layout
Zones consist of five areas: advance warning, transition, buffer, work area, and termination. Devices include cones, barrels, barricades, and diamond-shaped orange warning signs.
- All signs must be at least 36” x 36”.
- Signs must use reflectorized material as required.
Traffic Sign Classifications
Non-standard signs are not acceptable.
Variable Message Signs (VMS) / Boards (VMB)
Used to inform motorists of current or anticipated conditions and manage traffic lane access. Placement and message standards include:
- Located on level surfaces
- Legible from at least 650 feet in all lanes
- Placed before decision points and likely traffic backups
- Set right of the roadway and completely off the shoulder
Message requirements:
- Clear and concise
- One specific thought per panel
- Timely, accurate, and up-to-date
Delineation Devices
Barricades
Barricades serve to alert, prevent access, protect workers and equipment, and support signage or lights. They must:
- Not be placed in drive or bike lanes without proper advance warning signs.
- Be spaced to prevent vehicle/cyclist access—no gaps larger than 2–3 feet unless needed for local/emergency access.
- Use collapsible legs only (Type I and II barricades must not use fixed or stiff legs).
- Be marked with alternating orange and white reflectorized stripes sloping downward at 45 degrees in the direction of traffic flow.
Delineators
Markers that define traffic lanes or edges. Effectiveness depends on position, spacing, color, etc. At night, they must be reflectorized and maintained.
Used to:
- Channel and divert traffic in advance of the work zones
- Define travel ways, curves, or detour edges
Delineators must:
- Be made of impact-resistant materials
- Resist wind and turbulence
- Not roll into adjacent lanes if struck (avoid weighted buckets, car wheels, or round bases)
- Be at least 36” tall for vertical panels
Cones
All traffic cones must have reflective collars:
- One 6” band, 3–4 inches from the top
- One 4” band, at least 2 inches below the top collar
Do not use cones at night unless it's an emergency. Cones used overnight must be replaced with proper nighttime equipment, approved by Traffic Operations.
Illumination
Lighting increases safety by identifying hazards and guiding travelers.
- Barricade warning lights (flashing) highlight hazards and attract attention to warning signs.
- Steady-burning lights enhance visibility in curves, poor weather, or dusty conditions, and alert pedestrians/cyclists.
- Flashing yellow lights used for advance warning must be clearly visible above other reflectorized devices and be mounted at least 3 feet above the roadway.

Pavement Striping
Pavement striping and raised markers may be required for long-term construction projects where traffic is diverted. Their purpose is to ensure lane clarity and reduce driver confusion.
The Traffic Operations Department determines when striping is required, as well as what needs to be removed or re-striped.
Flagger Requirements
Flaggers play a critical safety role and must be alert, presentable, and capable of communicating effectively with the public. They must position themselves to control traffic before it enters the work zone and use adequate pre-warning signs. The use of earbuds or cell phones is prohibited while flagging.
Flaggers are required when:
- Workers or equipment intermittently block traffic or lanes
- Public and worker safety is at risk, or as directed by Traffic Operations
Flagger safety equipment requirements:

- Weather-appropriate attire
- Valid flagger certification card (copies not accepted)
Traffic Control Supervisors
All Traffic Control Supervisors (TCS) must carry a valid TCS card issued by the Colorado Contractors’ Association or the American Traffic Safety Services Association. Copies of cards are not accepted. TCSs must wear appropriate safety gear, including a hard hat, while on-site.
Arrow Panels and Message Boards
Arrow panels (also known as arrow boards) should use a bulb matrix and include a hood of no less than 180 degrees. These panels must be mounted or recessed appropriately.
Arrow panel display modes:
- Flashing arrow, sequential arrow, or sequential chevron
- Used for stationary or mobile lane closures on multi-lane roads
- Flashing double arrow
- Flashing caution
- Used for shoulder work or temporary lane closure on two-lane, two-way roads
Vehicles with arrow panels must also have rotating or strobe lights.
Minimum arrow panel size: 48” long by 24” wide. Contact the Traffic Operations Department or refer to the MUTCD for full specifications.
Pedestrian, Bicycle, and Transit Considerations
Pedestrians
- Safe and accessible pedestrian access must be maintained at all times.
- Detours must be ADA-compliant and clearly marked.
