3.4. City Network Condition Distribution Figure 11 shows the current (August 2022) distribution of pavement condition for the roadway network in Louisville. While direct comparisons to other agencies can be difficult due to variations in agency size, age, and recent development, the City is above average in condition and displays a distribution that suggest a continued investment in renewal. • Thirty percent (30%) of the network can be considered in "Excellent" condition and should be closely monitored to ensure timely application of early localized preventive measures. • Thirty-three percent (33%) of the network falls into the PCI range considered "Very Good". These are roads that benefit most from preventative maintenance techniques such as spot patching and slurry seals. • Sixteen percent (16%) of the streets are rated as "Good" and may still be candidates for slurry seals or thin overlays. • Twenty percent (20%) of network can be considered "Fair" to "Marginal" condition and representing candidates for progressively thicker overlay -based rehabilitation. If left untreated, they will decline rapidly into reconstruction candidates. • Two percent (2%) of the network is rated as "Poor" or "Very Poor", meaning these roadways have deteriorated to the point where surface rehabilitation can no longer restore the pavement to a point of structural adequacy. Rehabilitation of the entire pavement structure is required for these segments. 45 40 Current (Aug 2022) Network Average Condition = 73, Backlog = 2.1% 35 - 32.9 am 30 L Q Y 25 L 0 3 z 20 4- 0 W M15 Y u v10 a 0 0 Very Poor (0 to 25) Poor (25 to 40) Marginal (40 to 50) Fair (50 to 60) Good (60 to 70) Very Good (70 to 85) Excellent (85 to 100) Current Pavement Condition Index (CPCI) Using Descriptive Terms Figure 11- Roadway Network Present Status Using Descriptive Terms IMS Pavement Management Report Louisville, CO 2022 Page 1 24
