2018 Re-elect EdLARENAS


My love for the ocean started as a child enjoying California beaches with my family sailing, diving and surfing. During my college years I studied oceanography and biology. I spent summers working in commercial fishing and doing yacht delivery. I eventually settled on the Coastside, spending 12 years living on a sailboat with my wife and sailing the Pacific Ocean. I have lived in San Mateo County for almost thirty years and have participated in Harbor Commission meetings for over 15. These experiences have taught me the value of ocean protection, public access and the value of a Harbor Commission.

I have spent years doing volunteer work, including being Chair of the San Mateo Chapter of the Surfrider Foundation and starting a water quality testing lab 15 years ago. I have also collaborated with the Resource Conservation District and the Harbor District on water quality projects and advocated for public access -- the most recent being for Martins Beach.

I’ve been an invited speaker to Capitol Hill Oceans Week in Washington DC talking about ocean protection and have advocated for coastal protection before the State Legislature in Sacramento and before the California Coastal Commission.

In my college years as a research scientist I conducted oceanographic studies of northern California coastal waters and later, working in biotechnology, I led a multinational team of scientists developing biofuels.

As Harbor Commissioner I will use my skills as a scientist, project leader, and ocean advocate to improve the environment of our harbors, protect commercial fisheries, and enhance public serving facilities. Open government, transparency, and fiscal responsibility will continue and I will encourage public comment in planning.

I appreciate your vote.

  Sailing in San Francisco Bay

Sailing in San Francisco Bay


My wife and I have sailed over 30,000 miles, a large part of that as blue water sailing from California to Mexico, Costa Rica, Panama, Ecuador, Galapagos Islands, Marquesas Islands in French Polynesia, Hawaii, and back to Pillar Point Harbor, our home port. Our longest open water passage exceeded 3000 miles from the Galapagos Islands to the Marquesas. We have also sailed the coast of California and the Channel Islands off Santa Barbara countless times. We lived on sailboats for 12 years, in Pillar Point Harbor, Oyster Point Marina, Redwood City, and Palo Alto, before buying our home in Moss Beach. Today we still sail our 39 foot Cavalier out of Pillar Point Harbor and are members of the Half Moon Bay Yacht Club.  Living on a boat and sailing provides a unique understanding of the inner workings of a harbor and the importance of protecting our waterways and coastline.  It has also given us an appreciation of the value of visitor serving facilities and public access to our beaches and harbors.

I have been diving since I was 16. I am PADI, NAUI and Los Angeles County Advanced Diver certified. While sailing has given me a unique perspective of the ocean surface, diving has given me an appreciation of what lies beneath.

The sea, the great unifier, is man's only hope. Now, as never before, the old phrase has a literal meaning: we are all in the same boat.

Surfrider Water Quality Lab - testing water samples from Pillar Point Harbor and key points along San Mateo coast

Surfrider San Mateo Chapter

Under my leadership the San Mateo Chapter opened a water quality testing lab in 2001. We have sampled hundreds of water samples from Pillar Point Harbor, Surfer's Beach and other key points along the San Mateo coast. The lab measures the amount of indicator bacteria in the water which is used as an indicator of its potential as a health hazard. This information is posted online. Our lab is also used the Resource Conservation District to stage its studies on water quality.

I also do fun things on land.....

Working among a group of wonderful people in New Orleans to help build homes for families devastated by Hurricane Katrina reminds me to be grateful for what I have.
