(NCE), was selected by the City of Folsom (City) to update the pavement management program (PMP). The purpose of this report is to help educate policy makers about the current condition of the street network and the impact of various funding scenarios on the future network condition. The City’s pavement network consists of approximately 256.3 centerline miles of streets, 37 centerline miles of bike paths and 46 parking lots which represent a substantial investment of $378.4 million. NCE collected condition data for the entire network in 2019 per Metropolitan Transportation Commission (MTC) survey protocols. All inspection data were entered into the StreetSaver® database, which the City uses as a decision-support tool. Overall, the City’s street network is currently in “Good” condition with a pavement condition index (PCI) of 74, bike paths are in “Very Good” condition with a PCI of 90 and parking lots are in “Fair” condition with a PCI of 67. Of the entire network, 73.8 percent is in “Good” condition, 18.2 percent is in “Fair” condition, and 8 percent is in “Poor/Failed” condition. The budget needs analysis indicated that the City needs to spend approximately $76.6 million over the next five years to essentially repair all streets, bike paths and parking lots and bring the network into a condition that can be maintained with on-going preventive maintenance. Five budget scenarios were performed to illustrate the impacts of different funding levels. The following table summarizes each scenario with its corresponding five-year budget, PCI, and deferred maintenance at the end of the analysis period. Current 5-year 2024 Deferred Scenario 2024 PCI PCI Budget ($M) Maintenance ($M) S1: City's Existing Funding $2M/Year 74 $10.5 69 $84.8 S2: Maintain PCI at 75 74 $41.0 75 $52.8 S3: Best Management Practice 74 $85.7 81 $4.1 S4: Maintain Bike Paths in “Good” 90 $0.4 84 $1.5 Condition S5: Improve Parking Lot to “Good” 67 $1.4 69 $0.7 Condition NCE recommends that the City pursue additional funding to implement Scenario 2 for the streets and to continue to maintain bike paths in “Good” condition and improve parking lots to “Good” condition as described in Scenarios 4 and 5, respectively. These scenarios will require a total of $42.8 million over the next five years and the overall network PCI will be maintained at the current condition. This will also increase the portion of the network in “Very Good/Good” or “Fair” condition to approximately 91%. iv City of Folsom 2019/20 Pavement Management Program Update Introduction The City of Folsom (City) has utilized a pavement management program (PMP) since 2004. In 2013, the City converted to the StreetSaver PMP, which is the most widely used program in California. Nichols
