21 IV. PAVEMENT MANAGEMENT RECOMMENDATIONS Using the computer analysis, many alternatives were run to determine the optimum actions to extend the pavement life at the lowest overall cost. It was found that the key to achieving that goal is doing t h e right action at the right time. This will require City initiated actions rather than waiting for complaints or petitions. It is recommended that the City institute a maintenance and reconstruction program in accordance with the Cartegraph Criteria (Appendix C ) in order to start to tackle the deteriorating network of roads. It is recognized that the desire to maintain a high overa llAconditionAmustAbeAbalancedAwithAtheACity’sAfinancialA capabilities to fund the maintenance and reconstruction program. ItAisAbeingArecommendedAthatAitAbeAtheACity’sAintentAtoAmaintainAtheAcurrentAroadwayAOverallAConditionA Index rating of 66.95 as the l ong term average condition rating of its roadway system. In order to maintain this rating, it has been determined that the present level of maintenance and reconstruction activities, and therefore funding must be increased. Since this report was done in 2 004, the City has added close to 13 miles of roads and has increased funding for chip seals and overlays; however, hardly any funding has been spent on reconstruction of these roads . The average OCI has also dropped nearly 6 points since the report in 200 4. This report shows that if nothing is done to correct the current issue with road funding, the OCI will drop another 11 points in the next 10 years. Using the cost assumptions contained in the Cartegraph Criteria (Appendix C ) and the Total Maintenance C osts (Appendix D ) and Annual Maintenance Costs data (Appendix E ), the proposed funding shown in Figure 5 for special maintenance and reconstruction activities will allow the city to maintain an Overall Condition Index rating of 66.95 as the long term avera ge condition rating of its roadway system, comparable to the current overall condition. It is recommended that the total maintenance amount be budgeted in accordance with the plan year. This level of increased special maintenance and reconstruction fundin g will contribute towards improving the road network in the City over the next 10 years in comparison to continuing the past maintenance and reconstruction funding or providing no funding. This comparison of the projected amount of mileage of roadways wit hin each condition category and the projected Overall Condi tion Rating is shown in Figure 6 . This recommended maintenance program of spending $490,000 in maintenance and $2,000,000 in reconstruction would maintain the condition of the roadways. As previou sly stated, continuing the past funding levels over the next 10 years would require an estimated $4 5.7 million in 2023 (Plan Year 10), to restore the overall system at the end of that time period to only its current condition today. This report represents the initial presentation of data and analysis to the City Council for their use in the continuation of the development of an overall Pavement Management Program.
