Ledgestone Plaza
Overview
Ledgestone Plaza is a 76.03-acre mixed-use development in Kuna, Idaho — one of the most comprehensive integrated developments in Kuna’s southern growth corridor. The project combines 233 single-family homes, 192 multifamily units, and 6 commercial parcels, all served by a unified infrastructure system designed and engineered by Bailey.
The scale and complexity of Ledgestone required infrastructure master planning from day one. Bailey designed trunk water, sewer, and stormwater systems sized to serve all three land use types across multiple construction phases. The phasing strategy was engineered to deliver commercial frontage first, allowing the developer to begin leasing while residential phases continued behind.
This project exemplifies Bailey’s capability in large-scale, multi-use site engineering — coordinating residential, multifamily, and commercial infrastructure on a single site while maintaining a coherent phasing plan.
Bailey's Kuna planning intelligence indicated strong commission support for mixed-use developments that included commercial frontage along arterials — a pattern that shaped Ledgestone Plaza's site plan and contributed to a clean entitlement process.
Scope
- Mixed-use feasibility and infrastructure master planning
- Preliminary layout for residential, multifamily, and commercial sections
- Annexation and entitlement coordination with City of Kuna
- Phased grading, drainage, and stormwater management
- Water and sewer trunk infrastructure design
- Fire flow analysis for commercial parcels
- Roadway, access, and ACHD coordination
- Irrigation system design
- Multi-phase construction observation
Challenge
At 76 acres with three distinct land use types, Ledgestone Plaza required infrastructure master planning that accounted for residential, multifamily, and commercial demands on a single utility network. The commercial parcels needed fire flow capacity and access configurations that differed significantly from the residential sections, and the phasing plan had to deliver usable commercial frontage early to attract tenants.
Outcome
The project was fully entitled and built across multiple phases. Bailey's infrastructure master plan sized trunk utilities to serve all three land uses from the initial phase, avoiding costly upsizing later. The commercial parcels along the arterial frontage were pad-ready in phase one, matching the developer's leasing timeline.
