Carolyn Holmberg Preserve at Rock Creek Farm
Management Plan Update

Parks & Open Space is considering refinements to the current management plan to better balance the multiple uses of Carolyn Holmberg Preserve at Rock Creek Farm.


The primary objectives of the plan update are:

  • Create a working document that shows and respects the values and interests of all stakeholders.
  • Is balanced, flexible, and innovative in its approach.
  • Has been thoroughly analyzed through a thorough and transparent process.
  • Limits current and future conflicts.
  • Provides for the preservation and management of the area’s important agricultural, natural, cultural, and recreational resources.

The updated management plan is envisioned to:

  • Document the most up-to-date information about the property including its agricultural, natural, cultural, and recreational resources and open space activities.
  • Identify opportunities for enhancement to balance and optimize multiple resource priorities.
  • Consider input from public stakeholders and agency partners.
  • Inform future budget allocations and annual funding requests.
