Staff recommends the Planning Board recommend to the Board of County Commissioners that the preliminary plat of Collier Ridge Subdivision be conditionally approved and the Findings of Fact adopted as presented in the staff report.

On October 1, 2024, IMEG Engineering, on behalf of AA Properties, applied for preliminary major plat approval of Collier Ridge Subdivision. The proposed subdivision creates 51 lots for development over seven (7) phases.  The subject property is generally located east of Collier Road and north of Secret Valley Drive. The property is zoned RR3 - Rural Residential 3 and partially unzoned. The land is currently vacant.

VARIANCES
The applicant has requested a variance from Section 4.6.B.1 of the Yellowstone County Subdivision Regulations. Section 4.6.B.1 requires the subdivider to provide road connections to undeveloped land adjacent to the proposed subdivision. The maximum distance between connections to undeveloped lands shall not exceed 600 feet. In particular, the variance is waiving the requirement for a connection on the eastern portion of the subdivision, to parcel 1A of Amended Certificate of Survey 2156. The applicant is requesting this variance due to topographical concerns with the surrounding land. 

Staff is recommending an approval of this variance. The topographical constraints present at the site would prevent adequate connections at the areas required by the regulations. The proposed subdivision and adjacent property face mutual geographic constraints that prevent connections between the properties.

PROPOSED CONDITIONS OF APPROVAL

1. To protect public health and safety, prior to final plat approval, the applicant will receive approval from Montana Department of Environmental Quality (MDEQ) for all parcels less than 20 acres in size and the Yellowstone County Health Department for all parcels equal to or greater than 20 acres in size for the proposed water systems and septic systems
2. To minimize the effects on local service prior to final plat approval, the applicant will coordinate with the USPS to determine what type of delivery system is preferred and to locate and provide the correct amount of space for safely delivering the mail to the residents.
3. To minimize effects on the natural environment, prior to final plat approval a Weed Management Plan and property inspection shall be completed by the County Weed Department.
4. To protect public health and safety and provide for future road use, prior to final plat approval, the applicant will build the internal roads to county standards and create an Rural Special Improvement District (RSID) for the maintenance of those roads.
5. For the protection of public health and safety and to ensure protection of structures within the subdivision, it is strongly advised that the applicant submit a petition to expand the service area boundary of Blue Creek Fire Department to the Yellowstone County Department of Emergency Services in correlation with Montana Code Annotated (MCA) 7-33-2401.
6.

The Planning Division has received no public comment at this time.  Stakeholder input will be received at a public hearing scheduled for this subdivision on November 26, 2024.

In accordance with state law, the Board of County Commissioners has 60 working days to act upon this major preliminary plat. The 60 working day review period for the proposed plat ends February 3, 2025. State and County subdivision regulations also require that preliminary plat be reviewed using specific criteria, as stated within this report. The County may not unreasonably restrict an owner's ability to develop land if the subdivider provides evidence that any identified adverse effects can be mitigated. Within the 60 working day review period, the Board of County Commissioners is required to:

1. Approve;
2. Conditionally Approve; or
3. Deny the Preliminary Plat

The preliminary plat of this subdivision will have no financial impact on the Planning Division.

One of the purposes of the County's subdivision review process is to identify potential negative effects of property being subdivided. Negative effects that are identified become the subdivider's responsibility to mitigate. Various County departments, private service/utility providers and the affected school district/s, have reviewed this application and provided input on effects and mitigation.  The Findings of Fact, which are presented as an attachment, discuss potential negative impacts of the subdivision and conditions of approval are recommended as measures to further mitigate any impacts. In this case, there were found to be some impacts from this proposed subdivision.
