Referencing Table 6, above, Option 1 provides the most sustainable, most effective, highest level of service: 400 more miles repaired and $100,000,000 less expensive over 40 years than the next best option, and the entire backlog is addressed in the first 20-year cycle. Option 3 is the least effective option as indicated by the average cost per mile being $340,000 more than Option 1 and $53,000 more than Option 2. Option 3 is also the least sustainable and offers the lowest level of service of the three options, since this option allows the infrastructure to continue deteriorating further for an additional 20 years before addressing the backlog. The frequency of resident complaints will continue to increase and very expensive reactionary responses to concerns will further overburden the County’s routine maintenance budget. The series of figures below illustrate graphically the differences between the three options.
