Prior Funding: General Obligation Bond Revenue
• 1 year for replacing 4 swimming pools – Approved
• 4 years for flood recovery – Approved
• 20 years for flood mitigation and streets – Failed
• 10 years for flood mitigation – Failed
• 10 years for streets – Passed by voters in Nov. 2013
History of Local Option Sales Tax initiatives
2014 Local Option Sales Tax• A proactive approach
• 1% local option sales tax
• Effective July 1, 2014 – June 30, 2024
• Estimated to generate approximately $18M per year
• 100% of the revenues generated going toward the maintenance, repair, construction and reconstruction of public streets.
Launching the Program: First Years• Projects with minimal
underground utilities, no right-of-way needs
• Ability to show progress immediately
Community Outreach & Branding• Program name: “Paving for Progress”
• Signage on construction sites
• Public open houses to communicate plan
• Farmer’s Market, CR Kernels Game, other public events
• Program specific URL, website and social media presence
Desire for Comprehensive Pavement Management Plan
• Highest and best use of taxpayer dollars.
• Prioritization that is data driven, impartial, and measurable.
• Answers the need to reconstruct and rehabilitate poor roads while also maintaining good roads.
• Measurement and accountability
Developing the Plan• Iowa Pavement Management Program (IPMP) delivered first
round of pavement condition data in early 2014
• Pavement condition collected on 600 miles of roadways
• Pavement condition data were collected by a Fugro Roadware Automatic Road Analyzer (ARAN).
• Roads categorized: Very Poor to Very Good, with PCI
• PCI identifies appropriate treatment methods and strategy.
• Plan was under development by Spring 2014.

Treatment Methods• Reconstruction: The complete
removal and replacement of a pavement section
• Rehabilitation: Asphalt resurfacing, concrete patching, surface profiling
• Maintenance: Chip seal, crack filling and sealing, diamond grinding

Reconstruction
Renovating a pavement in fair condition will usually cost less than 25% of what it takes to reconstruct a failing pavement.
Data Preparation• Over 6000 individual roadway segments• Inconsistencies between City’s roadway geographic data and the
data supplied by IPMP– Street names– Need to add intersection points to define project limits
• History of individual streets was sparse and unreliable• Assumed pavement condition curves for each treatment (not
much long-term research to draw from)• ARAN vehicle did not collect data on curbs or storm intakes• Not aware of any other infrastructure prioritization efforts of this
magnitude. Someone has to do it first.
Prioritization Methodology• Used Deighton’s Total Infrastructure Asset Management
Software (dTIMS)
• Extrapolates remaining life cycle curve for all segments
• Assumes various treatment methods with associated costs
• Optimizes treatment plan for entire network within constraints:
– Funding estimates per year
– Location of segments (equitable distribution across City)
– Allocation between residential and arterial/collector roads
Initial CIP Details• Phased prioritization of projects
• Recommendations for treatment
• Investing approximately $18 million a year
• Improvements to 150 miles of roadway (50 miles reconstructed)
• Funding split between high traffic & residential (40/60)
• Tool for projecting future performance of road network
• Plan was presented to community in May 2015
Road Outlook Without Paving for Progress
Without this program, 90% of the Cedar Rapids road network would likely fall below the “Poor” condition threshold sometime in the next 10 years.

Miles impacted to date 11.3
Dollars invested FY’15 $16.5M
Challenges• Why not address worst roads first?
• The model recommendations have gaps (ex. 42nd Ave NE)
• Streets with roll-curbs are not appropriate for overlay treatments
• ADA compliance
• Implementing City’s new “Complete Streets” policy
• Are signals and bridges eligible items for LOST funding?
• How to integrate underground utility needs?
• City and Consultant capacity to manage & design projects
Next Steps• Creation of City Portal
– Reporting of performance metrics
– Recording completed project data
– Documenting underground utility needs
• Update to CIP in Winter 2015-16
– Refine model errors
– Re-prioritize model based on completed projects and as-built costs
– Incorporate underground utility constraints
