Planning & Zoning Commission/City Council

Planning and Zoning Commission

Island Park's Planning and Zoning Commission plays a crucial role in the zoning process. The commission reviews applications, holds public hearings, and makes recommendations to the City Council on zoning matters.

Zoning Administrator

The Zoning Administrator is responsible for the day-to-day administration of the zoning code. The administrator's responsibilities include:

  • Providing information and advice concerning zoning regulations

  • Processing building permits

  • Reviewing applications for completeness

  • Interpreting zoning district boundaries

  • Enforcing zoning regulations

  • Coordinating with other city departments and public agencies

Area of City Impact

Island Park has established an Area of City Impact that extends beyond the city limits. This area is important for several reasons:

  • It defines areas where future city growth is anticipated

  • It allows for coordinated planning between the city and Fremont County

  • Properties in this area are subject to special regulations

  • It helps prevent incompatible development on the city's periphery

If you're considering a property near Island Park but outside the city limits, it's important to determine whether it falls within the Area of City Impact and what implications that might have for development or future annexation.

Relationship to Fremont County Zoning

Island Park's zoning regulations apply only within the city limits. Properties in unincorporated areas of Fremont County are subject to the county's zoning regulations instead, with special provisions for the Area of City Impact. This distinction is important for several reasons:

Aspect

Island Park works closely with Fremont County on planning issues, particularly within the Area of City Impact. If you're considering a property near the city limits, it's important to verify which jurisdiction's regulations apply and whether annexation might be required or beneficial.

Understanding CC&Rs and HOAs in Island Park

Beyond city zoning regulations, many properties in Island Park are subject to additional restrictions through Covenants, Conditions & Restrictions (CC&Rs) and Homeowners Associations (HOAs). This is particularly common in newer subdivisions and recreational developments.

The Hierarchy of Property Restrictions

  1. City Zoning: The base regulations that apply to all properties within Island Park city limits

  2. CC&Rs: Private agreements that place additional restrictions on properties within specific developments

  3. HOA Rules: Specific regulations created and enforced by homeowners associations

Even if city zoning allows a particular use, CC&Rs or HOA rules may prohibit it. For example, a property might legally allow for short-term rentals according to city regulations, but the subdivision's CC&Rs might prohibit rentals of less than 30 days entirely.

Special Considerations for Island Park Properties

Island Park's unique character as a recreational destination with significant natural resources creates some special zoning considerations:

Short-Term Rentals

Island Park has specific regulations for short-term rentals, which are a significant part of the local economy. These regulations address:

  • Registration and licensing requirements

  • Occupancy limits

  • Parking requirements

  • Noise restrictions

  • Garbage management

  • Local contact person requirements

Environmental Protections

Due to Island Park's sensitive natural environment, zoning regulations include special protections for:

  • Wetlands and riparian areas

  • Wildlife corridors

  • Water quality

  • Scenic viewsheds

  • Forest resources

Seasonal Considerations

Island Park's seasonal population fluctuations affect zoning in several ways:

  • Infrastructure capacity planning

  • Seasonal business provisions

  • Snow storage requirements

  • Access requirements for emergency services
