Puente Hills Preserve News: November 2025

When voters approved Measure PH last year, it was for the benefit of the Puente Hills and local communities - to help prevent wildfires, to clean up illegal dumping and safeguard wildlife habitat. As we prepare to receive the funds in the coming months, we are also prepared to show you, the voters, how Measure PH works to preserve our hillsides.


Our goal after funds are received in the coming months is to highlight the ways we’re delivering for voters, protecting our hills, and keeping communities safe by providing regular updates on activities such as: 


  • Clearing brush from structures and emergency access roads for first responders
  • Protecting local natural lands by preventing and removing homeless encampments, vandalism and illegal dumping
  • Maintaining and adding park ranger patrols for fire safety, keeping our hills and trails safe and providing emergency response
  • Maintaining natural habitats, including the Hacienda Hills, Turnbull Canyon, Sycamore Canyon, Hellman Park, Arroyo Pescadero and Powder Canyon


We want your questions, feedback and ideas! Will you stay in touch? To learn more, please visit https://www.habitatauthority.org/measureph 


Please be sure to follow us on social media for Measure PH and many other updates as they become available. 


Forward this newsletter to friends and family so they can receive Measure PH and other updates too! 

Our Trails

Fall color comes alive: the leaves of poison oak, toyon and Western sycamores shift to brilliant reds and golds along the canyons.


Pro tip: Keep an eye out for poison oak’s color change — it’s beautiful but best admired from a distance!


Where to See It: the best Fall colors can be found on Sycamore Canyon Trail, Turnbull Canyon Trail, and Powder Canyon Trail.


Please also join our Meetup Group, where you can share photos and interact with fellow Puente Hills Preserve hikers.

Opportunities to Get Involved! 

Help bolster the work we do each day by joining one of the following committees, now with open seats available!


Fiscal Oversight Advisory Committee, Measure PH

The Habitat Authority Board of Directors has established a Fiscal Oversight Advisory Committee to provide guidance and annually report to the Board and the public on the use of Measure PH funds. This Committee will help ensure that the Special Tax proceeds are spent for their intended purposes. To support transparency, the Committee will review the annual budget and periodic budget updates prepared by the Habitat Authority and offer feedback.


Each volunteer position on the Committee carries a three-year term. See our fact sheet to learn more.


Citizens Technical Advisory Committee (CTAC)

Our long-standing Advisory Committee, created by the Habitat Authority Board, makes recommendations on selected items including community concerns, trails, and access; and works to preserve and protect in perpetuity the remaining habitat areas and secure tenuous wildlife crossing points. The Committee is made up of nine members from the surrounding communities. 


Each volunteer Committee position has a term of four years. See our fact sheet for details. 


Interested in applying for either of these committees? Please visit our website for more information.

In our last newsletter (July), we asked you about snakes - see the responses below!

"When it comes to snakes, how do you relate?" 

  • 23% reported that all of the answers resonated with them
  • 20% responded “I love snakes, they are great for the environment and help keep rodent populations in check!”
  • 15% responded “Snakes and I are more like fond long-distance friends”;
  • 14% selected “I have a new appreciation for rattlesnakes. I understand they are more afraid of me.”
  • 14% also selected “none of the above” as their response 
  • And then finally, 12% responded “I think rattlesnakes are super cute, but I would never pick them up.”

Current Fire Prevention Activities


In August, the Habitat Authority executed a grant with the Rivers and Mountains Conservancy for wildfire resilience. A part of this grant includes funding for fall/winter vegetation clearance, strengthening defensible space areas from adjacent structures and homes, as well as safeguarding emergency access routes for first responders. These grant efforts are above and beyond anything our budgets could provide.

Wildfire Prevention & Preparation: Home Hardening


With fire season year-round, it’s important to be vigilant and take preventative efforts, especially when it comes to protecting our family homes.


Embers travel 1 mile or more during a fire. Home hardening can help address your home’s vulnerabilities to better withstand a wildfire. 


What is Home Hardening?

Home hardening is the term used to describe vegetation management and building materials used to resist the intrusion of flames or embers projected by a fire. It can be applied to new construction or for retrofitting an existing home. 


Home hardening considers the relationship between your home and its exposure to nearby combustible features such as vegetation, vehicles, accessory buildings like a shed, or even miscellaneous structures like a fence.


Ways you can harden your home: 

  • Zone 0: remove combustible materials within 5 feet of your home
  • 1/8 inch wire mesh vents
  • Closed rain gutters
  • Chimney screens
  • Upgraded roof
  • Boxed eaves
  • Replace drapes with shutters or blinds
  • Dual-paned windows


Below is a great example of local Hacienda Heights residents’ recent home hardening and Zone 0 efforts.

BEFORE: wood siding and vegetation within 5 feet of the home (Zone 0)

AFTER: removed vegetation within 5 feet of the home and installed gravel; wood siding replaced with stucco siding; original windows replaced with dual-paned

With grant funds received from the Rivers and Mountains Conservancy for wildfire resilience, we have started a home hardening project on a Habitat Authority-owned facility and look forward to providing future updates.

We celebrated the Mid-Autumn Festival with a nature walk in Powder Canyon

Wildfire prevention: Every year, the Habitat Authority clears defensible space around the Preserve in accordance with local jurisdictional requirements. 

In October, we highlighted the bird migration season in Southern California, noting that migrating birds primarily make their long-distance flights at night, making the journey to search for milder climates in the winter.

The Habitat Authority is a local government agency, and is qualified to accept tax-deductible charitable donations including monetary and real property. Donations such as these contribute to the purpose of the agency and provide tax benefits for the giver.
