OH HB631

Authorizes 10 or more eligible municipal corporations within a single region to establish a regional economic development alliance for sharing services and resources, with only one alliance permitted per region.

Defines "region" as a central county (population at least 400,000 with charter) plus adjacent counties, allowing flexible regional boundaries when multiple central counties exist.

Establishes a resource gain allocation program where member municipalities contribute based on income tax growth exceeding inflation-adjusted baseline values, with contributions capped at 3% of annual income tax revenue or a different amount specified in the agreement.

Allocates contributed funds first to alliance operations, then to recipient members for infrastructure, economic development, or other municipal purposes, with remaining funds potentially directed to infrastructure, economic development, reserve, or other designated funds.

Requires initial allocation program terms of 5-50 years with up to four 25-year renewal terms, mandatory fifth-year program review by governing board, and two-thirds member approval for withdrawal from alliance.
