Summary

Supervisor Poe asked the board to reassess which roads the county maintains, citing outdated listings and failing pavement. The board directed Public Works to return with a written process and criteria for "road swaps," cost analysis and a five-year review cycle; staff estimated a $162 million 10‑year funding need to reach a maintainable network.

Supervisor Poe opened a lengthy discussion of county road maintenance on Oct. 14, asking the board to revisit the county-maintained roadway list and consider a "road swap" approach that would remove long-unused miles from county maintenance and add newly developed, populated roads where residents currently lack county maintenance.

Staff context and numbers: Public Works and consulting data presented in the meeting packet (Pavement Management Update, Nov. 2021) show Mariposa County's system with an average pavement condition index (PCI) of about 51 on a 1–100 scale. Staff reported roughly 25.7% of the network in good condition and 44% in poor or failed condition. The budget analysis in that report estimated approximately $162 million would be required over 10 years to restore the network to a preventative-maintenance baseline. County staff told the board that current annual discretionary road funding is well short of that need and that the county must aggressively pursue grant funding and add in-house engineering capacity to access larger state and federal grants.

Public comment and resident concerns: Dozens of residents described unsafe travel, lack of snow plowing on private roads, out-of-date maintenance lists, and impacts to mail delivery; one caller said neighbors had paid roughly $50,000 to pave a short segment. Several speakers urged clearer rules about when a road becomes county-maintained and how residents can petition for maintenance inclusion.

Staff recommendations and board direction: Public Works Director Shannon Hansen and County Administrative Officer Joe Lynch outlined a pragmatic way forward: (1) identify criteria used by peer counties (roadway cross-section, drainage, two 10-foot lanes and two-foot shoulders, demonstrated public benefit), (2) analyze candidate roads for a swap only if they meet county standards or if a funding mechanism is proposed to bring them up to standard, and (3) pursue grants and staff capacity to implement larger projects. The board reached consensus to direct Public Works to develop a written process that includes (a) a procedure for proposing and analyzing road swaps, (b) a cost-analysis methodology, (c) public engagement steps, and (d) a five-year review cadence. Public Works indicated a six-month timeline to present the proposed process and initial analyses.

Why it matters: Road condition affects resident safety, emergency access, mail delivery, and economic activity. The staff-reported funding gap and large share of roadway in poor condition mean that a strategic, transparent process for prioritization and for handling private versus county roads is likely to be necessary if the county is to target limited dollars efficiently.

Next steps: Public Works will return with a draft process and sample analyses within an estimated six months; board members signaled support for a transparent process that includes public input and clear technical criteria.
