Pavement Management Program Update – Cycle 3 Status & 2011 Program December 14, 2010 Regular Agenda Item – Approve 2011 Comprehensive Street Maintenance Program
|
Please include the following item on the City Commission regular agenda for consideration at the December 14, 2010 meeting:
Program Update . The first quarter of street rating Cycle 3 was completed in October 2010 followed by recent comparative analysis of the new survey data with existing data in the City’s pavement management program. This management program provides Public Works with a tool to maintain an inventory of street pavement, their respective condition and maintenance work history, and the ability to identify budget needs and impacts associated with preservation strategies and asset management. By applying this tool and with the continued support of the City’s citizens and representatives, the City has seen the implementation of a wide range of maintenance techniques from preventative maintenance measures to major rehabilitation and reconstruction. The expansiveness of maintenance activities are reflected in the attached 2006-2010 combined maintenance map.
Program Summary . Results of the street rating for Cycle 3 indicate the following:
- Average PCI has increased by 10.74% from Cycle 2
- Deterioration rates are slowing
- The percentage of streets in the “unacceptable” range has decreased from:
- Cycle 1 – 31.5% unacceptable
- Cycle 2 – 29.8% unacceptable
- Cycle 3 – 26.28% unacceptable
2011 Street Maintenance Program & Funding . In August 2010, the City commission approved approximately $5.85 million to be utilized for the 2011 Street Maintenance Program. The pie chart below gives a breakdown of the various funding sources. The “Proposed 2011 Comprehensive Street Maintenance Program” map is attached to this document. The map includes streets identified for crack sealing, microsurfacing, mill and overlay/curb and gutter, internal street maintenance project areas that include concrete rehabilitation work, and other project locations such as the KLINK and CIP/Sales Tax projects.
The proposed 2011 program map has been sent out for review to other departments, local utilities, consultants, and other local authorities for determination of potential impacts, conflicts, and coordinated work efforts including scheduling.
Action Request . Approve 2011 Comprehensive Street Maintenance Program.
