PROFESSOR POTHOLE PRESENTS Everything You Always Wanted To Know About Selecting Streets For Resurfacing In Your Neighborhood Council. To Know About Selecting Streets For Resurfacing In Your Neighborhood Council. William A. Robertson, Director Bureau of Street Services
Current Condition Assessment 6,500 miles street system Approximately 1,000 miles of failed streets Overall street system condition is a C-
How Did We Get In This Mess? Prior to World War II the City was comprised of approximately 2,500 miles of paved streets and the Annual Resurfacing Program (ARP) consisted of 50 miles. After World War II, and the rapid growth of the San Fernando Valley the street system grew to 6,500 miles. Up until 1986, the ARP still consisted of only 50 miles of resurfacing. From 1987 to the early 1990’s, the ARP was increased to approximately 150 miles. Fiscal Year 1994-95, the Bureau was funded for its first 200 mile ARP. This year the ARP is funded at 135 miles.
HOW CAN THE NEIGHBORHOOD COUNCILS COLLABORATE TO FIX THIS MESS?
2005 – 2006 ANNUAL RESURFACING PROGRAM WILL BE COMPRISED OF: Annual Annual resurfacing program funding, plus $100,000 $100,000 per Neighborhood Council.
Neighborhood Councils Responsibilities 1.Thoroughly know the street infrastructure of your neighborhoods. 2.Familiarize with the Neighborhood Council Infrastructure Assessment provided by the Bureau of Street Services (BSS). 3.Prioritize your needs as a Neighborhood Council. 4.Select a Public Works liaison / Public Works Committee. 5.Report to the BSS in a timely manner.
Types of Resurfacing Work Maintenance Overlays –A maintenance overlay is the application, by an asphalt paving machine, of from 1” to 1½” of asphalt wearing surface to a roadway. Once a roadway has deteriorated to the point of having poor riding and drainage qualities the application of a maintenance overlay is required. Resurfacing –Resurfacing is the placement by an asphalt paving machine of 2” (±) of asphalt wearing surface over a prepared subbase. The roadway may have had up to 25% by surface area involved in base failures. Reconstruction –Reconstruction is the placement by an asphalt paving machine of 2” (±) of asphalt wearing surface area over a prepared subbase. The roadway may have had from 26% to 100% by surface area involved in base failures.
How Can You Get More For Your Money? 3,300 ft. of Maintenance Overlays, or 2,640 ft. of Resurfacing, or 1,130 ft. of Reconstruction. $100,000 can provide the Neighborhood Council with: Note: A typical residential City block has an average length of 500 ft.

How To Read The Resurfacing Assessments? 2 2 No Base Failure 3 3 1% - 5% Base Failure 4 4 6% - 10% Base Failure 5 5 11% - 15% Base Failure 6 6 16% - 20% Base Failure 7 7 21% - 25% Base Failure 8 8 Reconstruct Note: Smaller number in rank indicates a better condition of the street. RANKDESCRIPTION
How Are Streets Selected? Street selection for the Annual Resurfacing Program is based on the Bureau’s Pavement Management System: –Defines the existing condition of streets. –Determines the most economical maintenance and rehabilitation strategy. –Predicts future condition of the street network based on different budget scenarios.
Why Don’t We Fix The Worst Streets First? 80/20 Allocation Plan 80% Overlays/Resurfacing 20% Reconstruction Spending more in reconstruction or using a “worst first” strategy would greatly reduce the number of streets resurfaced and cause an acceleration in the decline of the overall condition of the street system.
Pavements need to be managed, not simply maintained. Why Use Pavement Management?
Recommendations 1.Select streets that are contiguous to the other streets selected under the Annual Resurfacing Program (ARP). 2.Minimize the selection of streets that require reconstruction. 3.Provide the Bureau of Street Services with a priority list of resurfacing projects as soon as possible. (All projects need to be “cleared” by the utility companies as mandated by the Street Damage Restoration Fee Ordinance before they can be added to the ARP.)
