Civil Engineering in Kuna, Idaho.
Kuna is the Treasure Valley's longest-running growth story — from 6,400 residents in 2000 to nearly 30,000 today. The youngest median age in the valley, a 90% residential tax base, and a 2026 comprehensive plan update reshaping the Future Land Use Map. Bailey Engineering knows the council, the wider street sections, and the mayor who uses his tie-breaking vote.
A growth story with a structural commercial-development opportunity.
Kuna has grown more than 335% since 2000, from 6,400 residents to nearly 30,000 today. Located 18 miles southwest of Boise in Ada County, Kuna has the youngest median age (31.9) of any major Treasure Valley city and a property tax base that is 90% residential — which means the city actively welcomes commercial and mixed-use development to balance the burden.
A comprehensive plan update launching in 2026 is reshaping the Future Land Use Map, creating both opportunity and risk for applications filed now. The new FLUM was approved by the Ad Hoc Committee in March 2025 and forms the framework for the full plan update. Applications filed in 2026 may be evaluated against both the current plan and the spirit of the incoming one.
Kuna structurally favors commercial and mixed-use applications.
Mayor Stear has been explicit: Kuna's property tax base is approximately 90% residential. Home values have risen faster than commercial property values, compounding the imbalance. The city needs commercial and industrial development to reduce the per-household tax burden. This creates a structurally favorable environment for:
- Commercial applications on comp-plan-designated commercial land
- Mixed-use developments with retail or employment components
- Industrial applications in designated zones (not near residential — see data center controversy below)
- Annexations that bring commercial or employment land into the city
Purely residential applications face a more complex calculus — they add to the residential tax base dominance while generating school, fire, and road service demand.
The most instructive recent decision is the Gemstone Technology Park — a 620-acre data center rezone that passed on a 3-2 Council vote with Mayor Stear casting the tie-breaker. Council President Bruce's opposition was grounded in comprehensive plan alignment: the project was located near farmland and homes rather than in the designated industrial zone near the existing Meta facility.
What this tells civil engineers: comprehensive plan fidelity matters, especially to at least one vocal council member. Mayor Stear will break a tie in favor of economic development when the alternative is continued residential growth. 3-2 votes happen — Kuna is not a rubber-stamp council. Location relative to designated land use areas is a live issue, not just a technicality.
City Council, Planning & Zoning, and staff.
Kuna has a mayor who casts tie-breaking votes on consequential decisions and a council with genuine internal disagreement on comp plan fidelity vs. economic development opportunism.
City Council
Planning & Zoning Commission
Labels: CHAMPION ≥90% rezone approval rate · CAUTIOUS ≥75% · SWING ≥55% · SKEPTIC <55%
Planning Staff
Department: Planning & Zoning Department · City Hall: 751 W 4th Street, Kuna, ID 83634. Kuna's planning staff manages a high volume of residential annexation and subdivision applications relative to the city's size. The department is working through the comprehensive plan update process alongside normal application review — factor this into realistic response time expectations.
Verify your FLUM designation before filing any Kuna application.
Kuna is in active comprehensive plan transition. This is the most important planning intelligence signal for Kuna in 2026.
- March 2024: City Council passed Resolution R23-2024 establishing an Ad Hoc Future Land Use Map Advisory Committee
- March 12, 2025: The Committee approved a new FLUM proposal
- April 15, 2025: The new FLUM was presented to City Council
- 2026: Full Comprehensive Plan update process begins using the new FLUM as its framework
What this means for applications filed now: the existing "Envision Kuna" comprehensive plan is still in effect — but a new FLUM has been approved as the foundation for the coming update. Applications filed in 2026 may be evaluated against both the current plan and the spirit of the incoming one. FLUM misalignment was the central objection in the data center controversy. Verify your parcel's FLUM designation against the most current map before filing — and ask Kuna planning staff specifically whether the new FLUM proposal changes the designation for your site.

- Is Kuna a good market for commercial development right now?
- Yes — the city's 90% residential tax base makes it structurally motivated to approve commercial and mixed-use applications on comp-plan-designated commercial land. Mayor Stear has been explicit that commercial development is a priority. Applications on the right land with the right zoning face a favorable council environment.
- What is the Envision Kuna Comprehensive Plan and is it changing?
- Envision Kuna is Kuna's current comprehensive plan. A new Future Land Use Map was approved by the Ad Hoc FLUM Advisory Committee on March 12, 2025 and presented to City Council April 15, 2025. It forms the framework for a full plan update launching in 2026. Verify your parcel's current and incoming FLUM designation with Kuna planning staff before filing any application.
- What did the April 2025 data center vote tell us?
- The 3-2 Gemstone Technology Park vote (Mayor casting tie-breaker) established that large commercial/industrial applications can pass, but only with the right location relative to the FLUM. Council President Bruce's opposition centered on comp plan fidelity. Applications that deviate from designated land use areas will face similar arguments.
- What are Kuna's infrastructure concerns?
- Schools are the primary constraint — a recent bond failed and capacity is tight. Fire capacity is improving after a successful bond for a second station. Roads are managed by ACHD. Applications generating significant school-age population should include school impact analysis or fee acknowledgment.
- What street section standards apply in Kuna?
- Kuna requires a 36-foot back-of-curb to back-of-curb local street section — wider than the 33-foot standard in most other Ada County cities. This affects subdivision street design and cost estimates. Always verify with ACHD and Kuna planning staff for project-specific requirements.
- When does P&Z meet in Kuna?
- Second and fourth Tuesdays at 6:00 PM at Kuna City Hall, 751 W 4th Street. No meetings on fifth Tuesdays.
- What makes a strong annexation application in Kuna?
- Based on recent approved applications: FLUM-aligned zoning designations, a mix of residential and commercial uses (reduces the residential tax base dominance), proactive fire district coordination (donation of a future station lot is viewed very favorably), and ACHD-compliant road design. Applications that reference Envision Kuna's specific objectives by number in their narrative have a stronger record than generic compatibility statements.
Built for a city in active comp plan transition.
Kuna's growth trajectory — 335% since 2000, more annexations per year than almost any Ada County peer — means the city's planning process is constantly evolving. The 2026 comprehensive plan update adds a layer of navigational complexity that will trip up applicants relying on cached FLUM data or outdated code interpretations. Bailey Engineering's active practice across Ada County, including annexation and subdivision work in adjacent corridors, provides the current-state knowledge needed to position applications correctly in a transitioning regulatory environment. In a market where the mayor has a tie-breaking vote and uses it, local expertise is not optional.
