Council questions timing and scope of microsurfacing and sidewalk repair contracts
Summary
Councilors asked staff about selection, timing and funding for microsurfacing and pavement preservation contracts and how bond proceeds will be used to phase work. Staff said the preservation approach extends pavement life and that some work is contingent on street acceptance and condition.
Councilors questioned city staff about a pavement-preservation contract that would use microsurfacing and other treatments to extend street life. Staff said preservation treatments are chosen to apply the right treatment at the right time to extend the surface life and reduce lifecycle costs.
Public works staff explained that many streets in the program are two to three years old before the city formally accepts them and that microsurfacing is intended for streets in good condition earlier in their lifecycle. Staff said the program mixes treatment types and that some treatments are scheduled five to seven years after paving depending on conditions.
Council members also asked about developer reimbursement when preservation occurs shortly after a developer-built street is accepted. Staff said the city first reviews and accepts new streets before scheduling preservation and that reimbursement or credit arrangements depend on the street's acceptance and the underlying agreements.
On bond funding, staff explained that bond authorization and construction schedules are distinct: the ordinance creates the authority to spend, and cash flow/timing (and replacement with bond proceeds) will be handled as projects proceed. Staff said the council approved a resolution to begin the bonding process and that the initial bond tranche discussed was approximately $2 million.
Staff added that some pavement repair work requiring specialized testing or larger repairs is contracted out because the city lacks in-house capacity for repairs exceeding certain thresholds; staff estimated about 500 units (segments) would fall under that contract.
Ending: Councilors asked staff to return with lists of candidate streets and to clarify developer payment and acceptance policies before final contract approvals.
