What is Street - Three Flagger Closure – Denver, CO?
Street - Three Flagger Closure is a City and County of Denver Department of Transportation & Infrastructure (DOTI) traffic control plan drawing that shows the sign, cone and taper layout for a flagger-controlled work zone on a residential street.
The drawing is marked "Residential Streets Only" and "Drawing Not to Scale." It shows ROAD WORK AHEAD signs on the approaches to the work area, with placeholders reading "Enter Street Name Here" for the street being worked on and a prompt to "Indicate North On Plan." Its printed dimensions include signs about 100 feet apart on low-speed local streets (under 35 mph), cones 25 feet apart, a taper of 100 feet maximum, and a minimum 12-foot travel lane that must be maintained at all times.
The notes on the sheet set the contractor's responsibilities: resolve all local access and safety issues, place barricades, cones and signs in accordance with the latest edition of the Manual on Uniform Traffic Control Devices (MUTCD), and use certified flaggers who follow MUTCD guidelines and wear the required safety equipment. Sidewalks must not be blocked or encumbered at any time.
DOTI lists this sheet among its City Approved traffic control plans on its Street Occupancy page. The plan is a supporting drawing, not a permit: the permit itself is requested through the city's E-Permits system.
Who needs to file Street - Three Flagger Closure – Denver, CO?
Contractors and other applicants who are requesting a street occupancy permit from DOTI for work on a residential street, and who plan to control traffic with flaggers as shown on this drawing, use this plan. The City of Denver describes street occupancy as the short-term use of the city's right-of-way (ROW).
Conditions printed on the plan:
- It is for residential streets only.
- The sign spacing shown applies to low-speed local streets (under 35 mph).
- The contractor is responsible for resolving local access and safety issues.
- Flaggers must be certified and must follow MUTCD guidelines.
Do not use this drawing for street or alley closures related to special events (not construction); DOTI refers those to the Special Events Planning Guide, Section C: Events on Denver Streets. A Street Cut or Construction Permit does not replace the street occupancy permit: DOTI states that a Street Occupancy Permit is always required in addition to it.
When to file Street - Three Flagger Closure – Denver, CO
Submit the plan when you apply for the street occupancy permit it supports. DOTI states that all submittals through E-Permits must include the DOTI Street Occupancy Request Worksheet and traffic plans, so this drawing goes in with the application, not afterward. The drawing itself prints no separate due date. Because the permit covers short-term use of the right-of-way, complete the plan before you request the permit and check the Special Event Calendar that DOTI links on its Street Occupancy page to see whether your request may conflict with an event.
Documents you need
- DOTI Street Occupancy Request Worksheet: DOTI says all E-Permits submittals must upload it; the worksheet is used to calculate permit costs.
- Traffic plans: DOTI says all E-Permits submittals must upload traffic plans, which is where this completed Street - Three Flagger Closure drawing goes.
