Last Updated:



IBank's ISRF Loan Fund program provides low-cost, direct loans to local governments and nonprofits sponsored by public agencies for a wide variety of public infrastructure and economic expansion projects (excluding housing) that improve and sustain communities, helping individuals and families thrive. We focus on small and mid-/moderate-sized local governments and special districts — including those in underserved regions and communities.


ISRF loans can fund a wide variety of projects – including water and wastewater treatment plant upgrades or construction, venue or airport construction, or street repair and upgrades. ISRF financing is available in amounts ranging from $1 million to $65 million with loan terms for the useful life of the project up to 30 years.
