Local Infrastructure Improvement Program

LIIP

Funds infrastructure projects for South Dakota political subdivisions and tribal entities linked to local economic growth.

The Local Infrastructure Improvement Program (LIIP) is a quarterly grant program administered by the South Dakota Governor's Office of Economic Development (GOED) that funds the construction or reconstruction of public infrastructure tied to economic development initiatives. The Q3 2026 cycle carries a submission deadline of July 31, after which the Board of Economic Development considers applications at its September board meeting. Award amounts are not publicly specified and are set by the Board on a case-by-case basis.

Eligibility is restricted to political subdivisions of South Dakota (municipalities, counties), tribal governments, and local development corporations. Private businesses are not eligible applicants. Each applicant must identify a qualifying economic development project and collaborate with its area planning district to prepare and submit a complete application package. GOED disburses payment within 30 days of receiving required compliance documentation once Board approval conditions have been satisfied.

LIIP operates on four fixed quarterly deadlines each year — January 31, April 30, July 31, and October 31 — corresponding to board meetings in March, June, September, and December respectively. Applicants aiming for the Q3 cycle must submit by July 31, 2026. Strong applications demonstrate a direct linkage between the proposed infrastructure project and a specific economic development outcome such as business attraction, job creation, or industrial expansion in South Dakota.
