Council hears overview of TIFs, special assessment districts and new infrastructure‑development districts

Summary
City staff briefed council on differences among special assessment districts, tax‑increment financing (TIF) and newly available Infrastructure Development Districts (IDDs), explaining how each tool funds infrastructure, who bears the cost, and how the city negotiates public benefits with developers.
Sherita Allen, senior adviser for economic and workforce development, introduced a staff briefing on public‑finance tools and turned the presentation to a city housing and development expert identified in the record as Hanukkah Menderson. Menderson told council members the key distinction to take away is simple: “TIFs commit public funds to developments; special assessment districts don’t.”
Menderson outlined how special assessment districts impose assessments on properties in a defined area to pay for infrastructure and typically allow developers to access tax‑exempt bond financing that reduces interest costs. By contrast, she said, a TIF dedicates the incremental property‑tax revenue created by new development to repay upfront public investment, and TIFs often involve county participation if county taxes are pledged.
Menderson described the Infrastructure Development District (IDD), a new Tennessee tool enacted in 2024 with updates in 2025, as most useful for greenfield housing development. She said an IDD lets developers finance and deliver infrastructure up front and donate the infrastructure to the city; the financing is secured by a district assessment paid by homeowners in the district over time, rather than the city’s general‑fund debt. “This tool has been used extensively in Texas,” she said, noting the local law uses different terminology but similar mechanics.
Council members pressed staff on who holds the bonds and whether the instruments affect the city’s debt ratios. Staff replied the bonds are secured by the special‑assessment revenue (not the city’s general obligation), so they do not increase the city’s debt‑to‑income ratio. Members asked about typical terms; Menderson said 30‑year financing is common, and that once the bond term ends the district assessment typically expires.
On housing affordability, Menderson said IDDs can lower developers’ upfront capital costs and avoid rolling those costs into initial sale prices; savings passed through modestly to buyers, she said, while underscoring that these tools require negotiation to secure public benefits such as parks or affordable‑housing commitments. She recommended hiring financial consultants when the city contemplates these deals and noted the city already is sharing materials with other Tennessee jurisdictions exploring IDDs.
The presentation was informational; no formal action was taken. Councilmembers said they appreciated the overview and asked staff to return with policies and best practices if the city pursues IDDs or more special districts.
