The City of Hilliard is joining with key regional partners to advocate for more thoughtful, environmentally responsible land‑use policies as part of the first major update to the Big Darby Accord in nearly two decades.
In collaboration with the Hilliard City School District, Norwich Township, and Brown Township, the City has endorsed a joint letter expressing concerns about elements of the proposed Darby Accord update, particularly those affecting areas within the region that are most closely tied to Hilliard.
Hilliard City Council formally endorsed the letter at its Jan. 12, 2026 meeting.
Originally adopted in 2008, the Big Darby Accord is a multi‑jurisdictional agreement designed to protect the environmentally sensitive Big Darby Creek watershed while guiding responsible growth. With the Accord undergoing a comprehensive update for the first time since its creation, local governments are weighing in to ensure the next phase of planning continues to balance conservation with predictable development.
The joint letter highlights the importance of safeguarding the Big Darby Creek, one of Central Ohio’s most ecologically significant waterways, while also considering impacts on public safety, school capacity, infrastructure investment, and existing community plans.
A key point of concern is a proposed land‑use map within the draft update that would permit densities of up to 12 units per acre in parts of the watershed just south of Hilliard. That includes areas within the Hilliard City School District that would likely annex into the City of Columbus, if developed.
By contrast, Hilliard’s own development regulations within the Darby area limit densities to just 1.5 units per acre, a standard designed to protect natural resources and manage long‑term infrastructure demands.
Notably, under the current Big Darby Accord Watershed Master Plan, at least 50% of new development must remain open space. Hilliard has gone even further, preserving 70% of residential development and 60% of commercial development as protected land within the Darby region.
“Hilliard is proud to have emphasized environmental stewardship as a core community priority,” said Acting City Manager Dan Ralley. “However, a large increase in density within the sensitive watershed area could undermine decades of coordinated planning and place pressure on local services, schools, and natural systems.”
As the update process continues, Hilliard and its regional partners are urging residents to stay engaged and provide feedback on proposed changes to the Accord.
