The Planning Department ensures that the Town's development and growth are consistent with the Silverthorne Comprehensive Plan. Planning oversees the review of development applications such as site plan proposals, annexations, rezonings, PUD designations, conditional use permits, variances and sign permits.

Planning staff prepare amendments to the Town Code, long-term planning documents and studies and provide policy analyses and recommendations. Staff members provide support and input to the Planning Commission and Town Council.

Planning Applications

The final decision on most planning applications is made by the Town Council, with careful consideration of recommendations made by the Planning Commission. Approval or denial of applications is based on compliance with all applicable Town Code requirements and Town planning documents. The review process is designed to provide an opportunity for resident input at any stage, particularly during Community Meetings and Public Hearings.

Applications that require the approval of the Planning Commission and Town Council include:

• All subdivisions and plats (Subdivisions and plats create property boundaries, blocks, rights-of-way, easements, etc.)
• Rezoning (Zone districts determine the applicable requirements for setbacks, lot coverage, permitted residential density, etc. A rezoning is a proposal to change a property's zone district.)
• Annexations (Annexations incorporate land into the Town's jurisdicational boundaries.)
• Site Plan Modifications (Site plans lay out the features of a site, including parking, driveways, utilities, landscaping, snow storage, building location and architecture.) 
• Conditional use permits and variances (Conditional use permits are required for commercial or residential uses that are conditional within the relevant zone district). 
• Variances (Variances allow specific exceptions to the Town Code requirements in very limited circumstances.)
• Planned Unit Developments (PUD) and Major PUD Amendments (PUDs create custom zoning requirements for setbacks, lot coverage, height, architectural design, permitted residential density, etc.)

Applications that do not require Town Council or Planning Commission review include:

• Sign permits
• Comprehensive sign plans (Comprehensive sign plans create general requirements for all signage within a development to ensure cohesion). 
• Building permits for single-family homes, small projects, tenant finishes, minor exterior alterations
• Business Licenses (all business licenses for businesses located within Town jurisdiction are reviewed by the Planning Department to ensure compliance with zoning requirements. This includes home occupation permits. 
• Minor PUD Amendments (Small changes or corrections to an existing planned unit development). 
• Single Apartment Conditional Use Permit (A conditional use permit specifically for accessory dwelling units).
