RE:	Pavement Management Program Update – Cycle 4 Status & 2015 Program

Program Update

The first quarter (Phase 1) of street rating Cycle 4 was completed in November 2014 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 impacting overall Pavement condition Index (PCI) and pavement deterioration.  Contributing impacts of the program can be seen through the last several years.

Program Summary

Results of the current street rating data indicate the following (also see attached PCI map):

• Since the inception of the Program in 2006, the City has made progress to PCI goals as seen by the Average PCI progressive increase of 9.54% from Cycle 1 thru Cycle 4.  However, from Cycle 3 thru Cycle 4 so far, there has been no significant change in the overall PCI.  This indicates the program’s progress is slowing (see graph below).

• Deterioration rates overall are positive. However, some categories have begun a reversed trend downward (see graph below).

• The overall percentage of “fair to poor” streets has continued to decline but the overall change has begun to level out (see graph below).

2015 Street Maintenance Program & Funding

In August 2014, the City commission approved approximately $2.81 million to be utilized for the 2015 Contracted Street Maintenance Program.  The pie chart below gives a breakdown of the various funding sources.  The “Proposed 2015 Comprehensive Street Maintenance Program” map is attached to this document.  The map includes streets identified for maintenance work such as crack sealing, microsurfacing and patching, mill and overlay, curb and gutter, and internal street maintenance project areas that include concrete and asphalt rehabilitation work.  Other significant project locations and impacts such as the KLINK, CIP reconstruction, intersection geometric/signal improvements, Maple St Pump Station, and the CDBG projects are also shown.

Staff has also identified additional maintenance projects not included in the 2015 program (see map).  These identified streets are in need of maintenance based on their PCI’s.  They were identified as a need in order to keep positive PCI and deterioration rate growth.  The map represents a maintenance need of an estimated additional $3.5 million.

Staff Coordination & Recommendations

The proposed 2015 program map has been reviewed by the Utilities Department and the Bicycle Advisory Committee (BAC) as well as other private and public entities.  Public Works will coordinate potential conflict locations with Utilities Department including scheduling and phasing of projects.

Recommendations have been provided by the BAC per their January 20, 2015 meeting minutes.  Proposed 2015 Comprehensive Street Maintenance Program street locations with corresponding recommendations by BAC and Public Works are attached with some notations of complete streets elements included.

Action

Pending City Commission discussion, approve 2015 Comprehensive Street Maintenance Program.
