Site Development Permit
  
A Site Development Permit is required for projects that involve grading and/or filling activities. A Site Development Permit is also required for any development in the floodplains and wetlands and for projects that may result in soil erosion and/or drainage concerns. A Site Development Permit may be issued in conjunction with a Building Permit or may be issued independently depending on the type of activity.

A Site Development Permit is issued to assure that:

  • Development is in compliance with the Unified Development Ordinance and Federal and State regulations (e.g., wetlands, floodplains and erosion control).
  • Harmful environmental effects and negative impacts are minimized or mitigated.

A Site Development Permit may be required for the following activities:

  • Grading, filling and site restoration
  • Construction of new house, house additions and alterations
  • Construction of accessory structures such as detached garage, storage structures
  • Construction of non-residential (commercial) development
  • Construction of septic systems
  • Construction of seawalls
  • Subdivision construction
  • Wetland Jurisdictional Determinations
  • Any project that exceeds 1,000 sq. ft. of ground disturbance
  • Any project that would alter the existing grade by more then three (3) feet in vertical height

Winchester Rd, Libertyville, IL.  An application for a Site Development Permit must be made in person, by either the property owner or authorized agent.
