Civil Engineering in Boise, Idaho.
Idaho's capital and largest city — a mature, infill-driven market reshaped by the Modern Zoning Code. Bailey Engineering knows the council, the commissioners, and the staff who decide what gets built here.
An infill market with a more permissive council and a swing-vote PZ chair.
Boise is increasingly an infill story rather than a greenfield one. The city adopted a sweeping new Modern Zoning Code in late 2023 and updated it again in July 2025, reshaping how dozens of project types are reviewed. The council has grown measurably more permissive since mid-2025 — up 4.4 percentage points — and the rezone approval rate sits at 96.5%.
The catch: 19.1% of applications that clear PZ get a different outcome at City Council. That gap is the highest of any Treasure Valley city we work in, and it means PZ approval is necessary but not sufficient. Strong applications get briefed to commissioners directly, not just to staff.
City Council, Planning & Zoning, and staff.
Every Boise application moves through this same set of people. We know how each one votes.
City Council
Planning & Zoning Commission
Labels: CHAMPION ≥90% rezone approval rate · CAUTIOUS ≥75% · SWING ≥55% · SKEPTIC <55%
Planning Staff
Department: Planning & Development Services (PDS). Civil engineers most commonly interact with current planning staff on pre-application meetings, CUP and rezone submittals, and design review. All applications can be submitted, reviewed, and paid for electronically. Staff recommendations carry significant weight — the council follows them 81.4% of the time.

Compatibility
Cited in 36 denied motions. Most common objection in Boise by a wide margin. Address proactively with architectural context, buffers, and neighbor outreach.
Affordable Housing
Cited in 11 denied motions. The new zoning code includes affordability incentives; council members apply pressure on projects perceived to worsen housing access.
Density
Cited in 8 denied motions. More often a secondary concern alongside compatibility than a standalone denial driver.
How to prepare for each Boise vote.
Voting patterns from Bailey's planning data, current as of April 2026.
Generally supportive. Primary concerns are compatibility and affordable housing. Come in with clear evidence the project fits the neighborhood and doesn't worsen housing access.
Strong approval record. Same concern pattern as Nash. Rarely a source of friction for well-prepared applications.
Consistent supporter. Compatibility and affordable housing are the top flags to address.
Very reliable approval record. Compatibility first, then density.
Solid approval rate with the lowest threshold in the CHAMPION tier. Watch for compatibility and deferral requests.
The most likely source of a dissenting vote on the council. Raises compatibility, affordable housing, and density. Address them head-on in the presentation.
The most unpredictable voice in Boise's review process. Raises compatibility, affordable housing, and traffic. A SWING-labeled chair means PZ hearings carry more variance than in Nampa or Meridian. Prepare for pushback and have responses ready.
The last 90 days in Boise.
The new zoning code is still being stress-tested.
Boise's Modern Zoning Code went into effect November 2023 and was updated again in July 2025 via Ordinance 25-25. This is still a relatively new framework, and the first generation of applications navigating it are setting precedent. Projects that align with the code's stated goals — infill development, housing diversity, affordable unit incentives — are moving through the system faster and with less friction than those that rely on workarounds from the old 1966 code.
The opportunity: the new code created pathways that didn't exist before. The risk: commissioners are still calibrating what "compatible" means under the new framework, and Chris Danley's SWING rating at the PZ chair position means early-hearing outcomes are harder to predict than they were under the previous code.

Bailey Engineering's record in Boise spans subdivision and zoning text amendment work on corridors including W Clinton St, S Weideman Ave, and W Bel Air. That record reflects consistent alignment with what Boise staff and commissioners need to see. In a city where the staff follow rate is 81.4% and a new zoning code is still establishing precedent, having a team that knows how to build a submittal that lands with staff first — before it ever reaches a commissioner — is the difference between a smooth hearing and a contested one.
