SUB25-3 Subdivision

Corona Valley Subdivision - Preliminary Plat - Phase I

PROJECT SUMMARY

The application proposes a phased 180-unit residential subdivision on 38.803 gross acres, consisting of 22 detached single-family lots and 158 attached single-family dwelling units across all phases, for a gross density of 4.64 dwelling units per acre. The project is proposed to be constructed in five phases, each designed to function independently with respect to streets, water, sewer, stormwater, and emergency access.

The master plan includes 10 new internal public streets. Access to the subdivision is provided from the south via Ross Avenue, from the east via Booshway Street, and from the north via Cowboy Trail through LeGrand Pierre. Comanche Avenue and Cowboy Trail are proposed as 60-foot right-of-way residential collector streets, while all other internal streets are proposed as 54-foot right-of-way local streets.

The proposal includes park space featuring a full-size soccer/sports field, a youth-size soccer/sports field, parking, benches, landscaping, and picnic pavilions. The Preliminary Plat application encompasses the entire master-planned development. If the Preliminary Plat is approved, the first Final Plat will be for Phase I, which includes the required public infrastructure, park space, 14 detached single-family lots and 34 attached single-family dwelling units, for a total of 48 dwelling units in Phase I.

PROPERTY SURROUNDINGS

The parcel is located in an area experiencing active residential development. The Bear Run and Belle Vue Subdivisions are currently under development to the north, while Shoshoni Plains continues to expand to the northeast. Historically, this parcel, like others in the area, was used for winter trail access through an agreement between the City, the previous property owner, and Teton Trails and Pathways. The property’s northern boundary includes a right-of-way that is anticipated to develop into a future arterial street, which will be evaluated as part of this application.

PROPERTY HISTORY

In 2021, a previous owner applied to subdivide the 40-acre property to develop Rivers West Subdivision, a proposed 166-lot development consisting of attached single-family homes and 10 fourplex apartment buildings. The proposal would have required a zone map amendment or PUD. Following public hearings, the City Council unanimously denied the application in April 2022, citing concerns related to transportation plan conformance, code compliance, traffic impacts, park planning, and maintenance details. The applicant requested reconsideration, which Council reviewed in June 2022 and upheld the original denial. More information is available here: SUB21-4 Rivers West Subdivision - Preliminary Plat

APPLICATION REVIEW PROCESS:

Overview
The Developer is proposing a phased subdivision with a total of 180 dwelling units comprised of 22 detached single-family and 158 attached single-family homes, new public roads, and extensions of water and sewer infrastructure. The application is being reviewed through the City’s Full Plat Subdivision process (Art. 14.5.6) and is classified as a Large-Scale Subdivision (Art. 14.5.11). Because the proposed phases are part of a larger planned development area, the overall Master Plan is being reviewed with the application.

Applicable Plans & Ordinances
The codes and plans effective at time of submission (January 9, 2026) of the complete Preliminary Plat application are: The Land Development Code adopted by Ordinance 492-25 (effective November 26, 2025), the 2020 Comprehensive Plan, and the 2025 Transportation Master Plan.

Because this proposal is considered a Large-Scale Subdivision, the applicant is required to provide additional information regarding impacts on public services, infrastructure costs, projected tax revenue, and potential financing methods (Art. 14.5.11).

Full Plat approval is a three-step process: Concept Plan Review, Preliminary Plat, and Final Plat.

Concept Plan Review
The first step in the Full Plat Subdivision process is Concept Plan Review. The Concept Plan application is reviewed by the Administrator who will advise the subdivider in writing as to the general conformance or non-conformance with the applicable code. The review may include official and unofficial comments on policies and guidelines from the P&Z Commission in the implementation of various development ordinances such as the Comprehensive Plan, Land Development Code, and similar plans or programs. For large or complex proposals the Administrator may, at their discretion, present the Concept Plan to the Planning & Zoning Commission (PZC) for review and comment. The Concept Plan was presented to the PZC during a public meeting on October 8, 2025, where the commission reviewed the proposal and provided comments.

Preliminary Plat Review
The required neighborhood meeting was held on November 17, 2025. The Planning & Zoning Commission considered the Preliminary Plat application during a public hearing on March 11, 2026, where the item was tabled to allow additional information to be provided. The PZC considered the application again during a public hearing on May 13, 2026, and ultimately made a recommendation of conditioned approval to City Council.
                 Current Status: City Council held a public hearing on August 4, 2026 where the item was tabled to allow additional time for consideration of public comment and to receive further information. The application will return to City Council for consideration at a public hearing on September 1, 2026. City Council will make the final decision on the Phase I Preliminary Plat application.

Final Plat Review
Approval is granted by City Council after all improvements have been installed and inspected. All recommendations and approvals require public hearings except for the Final Plat (see Article 14.1, Summary of Review Authority). For phased development, such as the proposed Corona Valley Subdivision, the Master Plan of future phases must be submitted with the first phase. Each phase must obtain Preliminary Plat and Final Plat approval independently.
