WS – Item #4 WORK SESSION STAFF REPORT Work Session Item No. 4 Date: November 7, 2022 To: City Council From: Diane Hankee PE, City Engineer Re: 2022 Pavement Management Report Background The City’s Pavement Management Program evaluates the condition of the roadways and provides recommended maintenance. The program involves rating of one-fourth of the City roadway system mileage per year, and using pavement management software to project the condition of the remainder of the roadways. The City’s 2022 Overall Condition Index Map is enclosed. OCI Rating Miles of Road Percent of System Adequate 70.01-100 71 miles (68 miles 2021) 70% (68% in 2021) Marginal 40.01-70 25 miles (24 miles 2021) 23% (22% in 2021) Problem 0-40 9 miles (12 miles 2021) 7% (10% in 2021) The City’s roadway system weighted average OCI is 75.5. The findings reflect that majority of the roadways in the City are in adequate condition. The high rating is partially supported by new development construction in the recent years helping keep the average. The problem category has been reduced due to thin overlays, these roadways are expected to degrade back to the problem category within 10-15 years. There are approximately 5 miles of roadways have had thin overlays in the last 3 years. The thin overlays allows the City time to fund these roadways in the future. The pavement ratings along with traffic volumes, maintenance data, and geotechnical information is used for the City’s Roadway Capital Improvement Planning (CIP). The CIP is found on the City’s website under Engineering Resources. Since 2005 the City has completed 71 miles of preventative maintenance including crack filling, chip sealing and reclamite projects. The City has also performed 39 miles of pavement structure improvements including reconstruction, reclamation, mill and overlay and thin overlays. Requested Council Direction Information only.
