Best Urban Beaches

Visit NRDCs Switchboard Blog

As an urban dweller and water advocate, I love the Huffington Post's
contest to rank the best city beaches in the United States
. It's true
that many of our coastal cities boast some spectacular, easily
accessible beaches.

But all too often they also offer something else: an elevated risk
of contracting rashes and diarrhea because failing urban pipes dump
untreated sewage and polluted stormwater flows right into our beaches
after heavy rains.

The number of these events is startling. Every year, NRDC releases Testing the Waters: A Guide to Water Quality at Vacation Beaches. In this year's
report, we discovered that there were more than 20,000 days of closings
and advisories in 2008 because beachwater exceeded public health
standards.

For instance, one of Huffington's featured beaches, Zuma Beach in
Los Angeles County, exceeded health standards for beachwater quality
(indicating the presence of human or animal waste) 11 percent of the
time in 2008. While some beaches fared worse, that's 4 percent higher
than the national average, and shows that Zuma is prone to dirty runoff.

This is the case in communities all around our country, but the
effect is more intense in metropolitan areas. When it rains on city
streets, water rushes into storm drains pulling oil, toxins, pet waste,
fertilizers, and trash along with it.

In many cities, stormwater gets passed through the same pipes as
sewage, and when the system gets swamped by a downpour, the sewage
sometimes bypasses the treatment plant and gets dumped raw--with all
its cargo of infectious bacteria, viruses, and parasites-upstream from
 urban beaches.

This is what occasionally happens at San Francisco's Ocean Beach,
another beach included in Huffington's contest and one popular with
surfers. City officials closed certain stretches for several days in
2008 because mixed stormwater and sewage was discharged after heavy
rains.

The best way to keep beaches open is to keep the pollution out of the water in the first place.

Federal and local governments can make this a priority by requiring
better controls on stormwater and sewage. A key solution is to use
something called low impact development--techniques that retain and
filter rainwater where it falls, letting it soak back into the ground
rather than running off into waterways.

But in the meantime, if you want to enjoy the last days of summer by
taking a dip in your city's best swimming holes--and you want to avoid
a trip to the emergency room--take a look at NRDC's beach guide before
you go. It will tell you how well your city officials monitor local
beaches and how often they have exceeded health standards.

You can also take a look at our 5-star rating guide for 200 of the
nation's most popular beaches. This is a good place to find swimming
options that are fun and healthy.  The water at these beaches
is monitored more than once a week and almost always meets public
health standards.  In addition, the public is promptly informed
whenever contamination is found.

Here is a sample of some well rated beaches (5 stars):

  • Gulf Shores Public Beach (AL)
  • Laguna Beach-Main Beach (CA)
  • Bolsa Chica State Beach in Huntington Beach (CA),
  • Newport Beach (CA)
  • Ocean City (MD)
  • Park Point - Community Club Beach in Duluth (MN)
  • Hampton Beach State Park in Hampton (NH).
