The 79-acre Hawthorns area of Windy Hill Open Space Preserve was protected from development when it was gifted to the Midpeninsula Regional Open Space District in 2011. Since then, staff have been working to restore native grasslands, improve community wildland fire safety and protect historic features on the property. A multiyear public process began in 2021 to explore the feasibility of introducing ecologically sensitive public access to the undeveloped portion of the property.
Fieldwork at the Hawthorns Area
Midpen is conducting ongoing fieldwork and technical studies at the Hawthorns Area to document existing property conditions. Fieldwork may entail survey equipment, vehicles, and personnel within or around the Hawthorns Area. These activities will not result in any immediate improvements but will be used to inform future discussions regarding the location of public access facilities (such as parking areas and trails) within the Hawthorns Area. Please submit questions or inquiries using the comment card available below on this webpage.
There will be multiple opportunities throughout development of the Hawthorns Area Plan for public input. To stay informed, please sign up using the comment card below to receive updates. Additional information will be provided on this webpage as the project proceeds.
Hawthorns Area Plan Q&A
As a part of the Hawthorns Area Planning process, Midpen has collected many questions during our public engagement process. Click below to read the answers to these questions and to learn more about the Hawthorns project.
We have a new public survey available as part of our public engagement process for our Hawthorns Area Plan.
The results will be used by the project teams to guide the project. The anonymous survey takes about 10 minutes to complete.

Restoration
The Hawthorns Area includes rolling grassland, oak woodland and year-round flows in Los Trancos Creek that support a diverse community of native plants and wildlife. To protect the natural environment, Midpen removed debris and old vehicles from the property. Midpen staff also partnered with Grassroots Ecology to restore the property's native grasslands, including carefully timed mowing to reduce the spread of non-native yellow star thistle and removal of non-native, highly flammable French broom.
Working closely with the Woodside Fire Protection District fire marshal, Midpen also completed significant vegetation management on the property to improve community wildland fire safety, including creating a new shaded fuel break, emergency vehicle staging area and disked fire lines.
Hawthorns Historic Complex
The property was originally developed in the late 1880s as a summer estate. For more information, please visit the Hawthorns Historic Complex page.
