Golden Gardens

This time of year, the highest tides arrive right around sunrise. A couple of days after Christmas I headed out early to Golden Gardens to see the effect of the month's highest water levels. The predicted high tide was 12.7' above MLLW (Mean Lower Low Water or a "0" tide).  According to the Seattle tide gauge, the actual water level may have come in a couple inches higher.   These photos were taken 15-30 minutes after the peak tide.


This is not an unusually high tide.  A 13' tide (these numbers hold for central Puget Sound, but would need to be adjusted for other areas) occurs an average of 7-8 times a year, although the annual variability is huge.  Some years never see a 13' tide at all.  And in El Nino years, we may get 20 or 30!  (Alki Beach:  January 2010).  


The number of high tides at progressively higher levels falls off quickly.  In Seattle, Mean Higher High Water (the average of the highest high for every day of the year) is 11.35' - and we can expect a couple hundred every year.  As noted, 13' tides average less than 8 times a year.  And 14' tides take extraordinary conditions:  either a strong El Nino, like January 2010, or a big storm with a strong surge (February, 2006). Seattle's highest high tide was 14.5' and occurred on January 27, 1983 (another El Nino year).


In these photos at Golden Gardens, we see that the still water level is probably a foot or so below the sandy berm, but that the runup of the waves is just enough to send water over the berm crest.  Berm elevations vary and can depend on wave exposure and the abundance of gravel, among other factors, but 2' above MHHW is often a good place to start.

Golden Gardens

January 1st, 2020. New Year's Day. The sun came out. I was already in Ballard and somewhat impulsively decided to go to the beach. I wasn't the only one with that idea. 

Golden Gardens Park is located on Meadow Point, just north of the big Shilshole Bay Marina. It's got a long history, some of which I've mentioned in previous posts, but in the end, it is one of Seattle's nicest beaches and a great example of a fairly unconstrained urban beach. So many urban beaches in other cities are pocket beaches stuck between piers or heavily nourished beaches on intensely developed waterfronts. It's not that Golden Gardens has lost it's connectivity with adjacent beaches (it has) or that it hasn't been modified or nourished (it has, but not much), but it still looks and feels like a relatively natural beach. As long as you sort of ignore the marina, the railroad, and the crowds!

It was a beautiful day. Kids were playing in the water (barefoot and sometimes wearing down jackets). Families had gathered to burn their Christmas Trees. A few people were playing volleyball. The playground was full. So was the parking lot.

Golden Gardens

It's amazing that in over 430 entries and more than 5 years, I have never posted anything from Golden Gardens, even though it's the closest beach to my home and does not lack for interesting stories.

Early on the morning of July 4th, the beach was still quiet. A few vans were unpacking for the day's activities and people were beginning to mark territory for the afternoon's celebrations, but not much more was going on.

The north beach is gravel and sand and has retreated over the decades, perhaps aided by railroad, which was built along the eroding bluffs to the north and eliminated a potential source of sediment. In the mid-1990s, the City chose to nourish the north beach and restore the wetlands behind the berm. Both have done well in the 15 years since.

Meadow Point (the name of the landform, Golden Gardens is the name of the park) is the site of one of the largest relatively intact (although by no means original or pristine) backshore dune areas found in central Puget Sound. Keeping the Scot's Broom and other obnoxious vegetation in check is a full-time job for the city and the park's volunteers.

North storms appear to dominate sediment movement at this site, since this shoreline is sheltered from the more common southerly waves by West Point. The large Shilshole Marina and it's breakwater to the south may also influence Meadow Point - they certainly represent an abrupt end to the beach south of the Park.

The southern beach is swash-aligned, forming a broad crescent that faces the southwesterly waves. It is broad and sandy and by later today will be filled with people throwing frisbees, playing volleyball, picnicking, and launching kayaks. The north beach tends to be more for beach walkers and kite flyers.

Unlike Seattle's other beachfront parks where fires are prohibited, here they are not. Which probably explains the remarkable lack of drift logs on the berm.

Dixie Lee wanted to put the aquarium at Golden Gardens. Wolf Bauer did not. In the late 1960s and early 1970s, they argued about it, but in the end, the aquarium ended up on the downtown waterfront. This is neither the first nor the last beach that Wolf saved. Fittingly, Wolf was a key part of the design team that developed the 1996 beach restoration work.

Wolf,

As you begin your second century, I wanted to remind you of what an amazing difference you have made for Puget Sound shorelines and for the people who visit them.

You were instrumental in raising awareness of shorelines and in creating a demand for shoreline protection.  Today, it’s easy to take our beautiful beaches for granted, but without the amazing efforts of you and others in the early 1970s, this place would be a very unattractive place.  Your language and your ideas have remained lasting elements of Shoreline Master Programs across the state.

You described accretion beaches as an endangered species.  At the time, you may have doubted our progress, and it’s true that we have lost some special places.  But thanks to your work, many remain intact and more are becoming public.  Lily Point on Point Roberts is now a county park.

In the 1980s you spoke adamantly of the need to restore our urban beaches and to enhance the public’s shoreline experience.  But you did not just talk about it, you gave us examples.  Today, we have examples everywhere: in Seattle, Tacoma, Bremerton, and elsewhere.  And there are a new generation of projects such as the Sculpture Park Beach in Seattle and Marine Park in Fairhaven that were inspired by your example and carried out by impassioned individuals who had learned from you.

People enjoy our most spectacular urban beaches, yet many do not realize that these places were once buried in riprap and would be still were it not for your efforts.  People love the beaches at Discovery Park, Golden Gardens, Birch Bay, West Vancouver, and Tolmie State Park.  They think these places have always been this nice!

This year, we are mapping feeder bluffs throughout the Sound – the feeder bluffs that you taught us were such a critical element of the shore-process corridor.  Also this year, I was approached about what to do about salt marshes choked with cut logs from decades of sloppy log-rafting practices.  I jumped at the chance to share your presentation on this subject from almost two decades ago.

Increasingly, parks managers and and government regulators and fish biologists are looking for opportunities to restore beaches and to put sediment back into the system, not lock it away behind walls of rock.  People still build bulkheads, but doing so is widely discouraged and is increasingly difficult. In some places we are actually pulling seawalls off the beach and removing riprap from our spits.

Your legacy runs deep on Puget Sound and our shorelines are far, far better places today than they ever would have been without your incredible passion and your tireless commitment.

Thank you,

Hugh

NOTE:  Wolf turned 100 on February 24th. These photos, most taken recently, are all nourished beaches designed by Wolf in the 1970s and 1980s. Their captions link (in most cases) to previous posts on those places. Previous Gravel Beach posts mentioning Wolf can be found at:  Bauer Posts.

Blue Ridge

Seattle's Blue Ridge neighborhood lies on the hills that rise from the beach north of Ballard.  The community even has its own private beach access, but Sunday's low tide (-3.6' MLLW, so one of the year's lowest) made this a much more public beach, with a lot of folks walking between Carkeek Park and Golden Gardens.

AERIAL VIEW

A couple of small streams - not sure what distinguishes a stream from a stormwater outfall in these urban areas - emerge from culverts beneath the tracks at the Blue Ridge access. The larger one takes a sharp, but brief, right hand turn, before turning again down the beach.  I guess this suggests drift, or at least recent drift of the sandier material, is northward, although I think the larger pattern is the other way, since this area gets some shelter from the south.


The railroad dominates the upper beach - pretty much replaces it, actually - except for a narrow backshore right around the stream mouths.  But the lower beach goes out forever, or so it seemed today, when low tide sort of merged into the gray day.
