What are the impacts?
• Shortens the daily working window
• May need more days to complete work
• Some work needs to be completed in one event
• More days of lane closures, more impacts to traffic
• Limited flexibility for an earlier start to avoid summer heat • Availability of contractors, may give priority to other work or agencies
• Increase in cost for contractors and city staff by limiting working window
*This does not apply to emergency repair work or continuous traffic control set up for multiple days.

Options

Pros and Cons
Option A
Project by Project Closure Timeframes
(Staff Recommendation)
Option B
No street closures before
8:30 am
Pros
• Standard industry practice
• Provides greater flexibility to tailor closures to the needs of the project and local area
• Allows for a longer working window = fewer work
days required to complete projects
• Lower cost (than option b)
• Closure time frames based on unique project
needs
Pros
• Consistent lane closure time for most projects
Cons
• Shorter working window = additional days of work
• Inflexible window leads to greater risk of rushed
work, sacrificing safety/quality
• Increased costs
• Reduced flexibility to address site-specific issues
• Lane closures will still occur before 8:30 am for
certain projects and emergencies.
