Automatic External Defibrillators

Midpen is equipping all of the agency’s 36 emergency response vehicles with life-saving Automatic External Defibrillators (AEDs).  These portable electronic devices, when applied in combination with Cardio Pulmonary Resuscitation (CPR) by a trained emergency responder, diagnoses life-threatening heart conditions in a patient and is able to treat them through the application of electrical therapy to allow the heart to reestablish a normal rhythm.

Philips HeartStart AEDA portion of the cost of the AEDs was supported by funding from Palo Alto-based Racing Hearts non-profit organization.   Racing Hearts has obtained grant funding from the Santa Clara County Board of Supervisors to support local agencies and organizations in purchasing this life-saving equipment.

District rangers are trained emergency medical responders, who respond to over 150 medical calls and accidents a year.  Midpen encourages everyone to obtain CPR training.  The training is available through the American Red Cross and American Heart Association.

Mount Umunhum Road Closure

Another Measure AA Project in Progress

We are working to improve the road and summit of Mount Umunhum so that we can open it to the public. Our goal is to have the summit open to the public by Summer 2017.

In the interest of public and contractor safety, the following closures will occur.

Weekdays, beginning Monday, September 12th

Mt. Umunhum Road will be closed from Jacques Ridge parking lot to the summit. Only local vehicle traffic, contractors, and approved District staff will be permitted past Jacques Ridge parking lot.  Other vehicle traffic along with bicyclists, equestrians, and hikers will not be permitted on the road Monday through Friday for the duration of the project (estimated to finish in Summer 2017). The Jacques Ridge parking lot will continue to be open during regular preserve hours.

Weekends (Saturday and Sunday)

Mt. Umunhum Road will be open for all uses up to the Bald Mountain Parking Area only.  Only local vehicle traffic will be allowed past this point. Bicycles, equestrians and hikers will not be allowed on the portion of the road above the Bald Mountain Parking Area at any time.

Additional Trail Closure

Barlow Road (trail) will be closed between Woods Trail (part of the Bay Area Ridge Trail) and Mt. Umunhum Road for the duration of construction on both weekdays and weekends.

Please note: residents and visitors can expect increased construction traffic along Hicks Road, Alamitos Road and Almaden Road.  For public safety, the District also reserves the right to close Mt. Umunhum Road at any time without prior notice.

We thank you for your patience during this time. We are targeting the completion of construction by Summer 2017. This information will be updated as the project progresses. There will also be a phone hotline with updated information. This hotline may be reached by calling 650-691-2154.
