Public works outlines landfill savings, future cell planning and new approach to RSA capital

Public works leadership briefed the assembly on recent operational improvements at the central landfill and a proposed shift in how the borough funds RSA (road service area) capital projects.

Staff described improvements at the landfill campus including entrance and tipping-floor upgrades to reduce traffic backups, a new compost area and a glass pulverizer that has diverted more than 80,000 pounds of glass in recent months. A newly installed leachate evaporator can process up to 20,000 gallons per day at an estimated cost of six cents per gallon, producing roughly $270,000 in annual savings compared with hauling leachate to Anchorage for disposal.

The presentation noted the expansion of the municipal solid-waste cell four, extending landfill life by several years, and set a planning horizon for closure of cells 2B and 3 around 2029 and for cell five’s design/construction around 2032.

On roads, public works explained that maintenance-contract costs surged in recent years (maintenance-contract spending rose from roughly $8 million in FY22 to about $17 million), though rebidding and increased competition produced lower bid results for some contracts. The department recommended transforming the long-standing RIP (needs) lists into disciplined multi-year capital programs that put money into project accounts, set timelines and increase accountability so projects can be completed rather than left unfunded.

Assembly members asked about options to cap per-mile bids, break RSAs into smaller bid packages to attract contractors, and the challenge of matching limited revenues to capital needs. Staff said the new urbanized-area/MPO funding streams (anticipated metropolitan funds) offer additional avenues but also complicate RSA match and mill-rate decisions.

Direct quotes from the presentation included: "With the new evaporator... we're generating about $270,000 in annual savings," and "we need to move away from the RIP list and transfer into more of a capital program," reflecting stewardship and process-change proposals.

The assembly directed staff to provide project-level details in the upcoming budget book and to continue conversations with RSA advisory boards as capital project accounts are established.
