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
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 — Bailey designs every Boise submittal to land with staff first because the Council's follow-through rate is high enough to make staff alignment the single strongest predictor of approval ( ).

Compatibility
The dominant denial driver in Boise by a wide margin. Bailey's per-applicant playbook covers the architectural-context, buffer, and neighbor-outreach evidence packages that have historically defused compatibility objections at hearing.
Affordable Housing
The Modern Zoning Code's affordability incentives have made housing access a recurring Council concern. Bailey tracks which framing patterns have moved which Council members and shares the playbook with active applicants.

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.

- More permissive since mid-2025 ( ). The Modern Zoning Code is settling in and creating clearer pathways for infill and mixed-use development.
- What makes a strong rezone application in Boise?

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 staff alignment is the strongest predictor of approval 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.
