Harrisburg approves growth-boundary agreements with Sioux Falls and neighboring city

The Harrisburg City Council voted to approve Resolution 2025-17 establishing a growth boundary with the City of Sioux Falls and Resolution 2025-18 establishing growth boundaries with the City of T. Staff told the council these resolutions align Harrisburg—s planning limits with neighboring jurisdictions and follow Sioux Falls— water-service territory boundaries.

City staff said the two resolutions have been under development and were discussed at a recent study session; staff also noted the City of Sioux Falls and the City of T recently took similar actions. The resolutions include planning and annexation language appropriate to intergovernmental coordination; staff said the Sioux Falls boundary follows water-service territory lines, which are important for directing growth.

Councilmembers had no extended debate; both motions passed by roll call. Representatives from the neighboring jurisdictions were present at the meeting and available to answer questions.

Officials said the formal boundaries provide clarity for long-term planning, capital improvements and service delivery, and the items were described as part of an ongoing metropolitan coordination effort rather than immediate development approvals. The resolutions will be entered into municipal records and used in future annexation and planning work.
