Latest Studies: More Bad News...

It's been a long time since my last post. So what's new? Nothing as far as action by the Hawaii State Legislature or Honolulu City Council in regards to protecting public beach access, or protecting what's left of our shorelines.

Yet each week/month/year that goes by, we continue to see more evidence of climate change that is causing sea levels to rise and leading to accelerated beach erosion. On today's Civil Beat website, there was this piece (click here for link to their page):

Inch by Sandy Inch, Hawaii’s Loss of Beaches Worries Tourism Industry

Recent reports cite concerns that elevated ocean levels, drought and hotter Hawaiian nights will hurt tourism and ultimately the state's economy.

·By Breana Milldrum
The look of paradise is changing: Rising seas mowing over reefs that were once able to slow and break the swells are starting to swallow Hawaii’s iconic white beaches. The state has approximately 750 miles of coastline, according to a climate change report released recently by the University of Hawaii Sea Grant Center for Sustainable Coastal Tourism. But 13 miles of beaches have disappeared within the past century.

That has scientists — and the Hawaii Tourism Authority — worried. In a two-part report published in 2013 and 2014, researchers outlined impacts related to sea level rise, drought, and elevated temperatures in Hawaii.

“The first report was more of an academic, theoretical approach on how to deal with the problem,” co-author and NOAA Sea Grant Coastal Programs coordinator Dolan Eversole said. The second, released just a few weeks ago, attempts to illustrate how the effects of climate change will look on the ground, Eversole said.

Waikiki is particularly vulnerable. A 2008 economic impact report surmised that $2 billion in total visitor expenditures annually would be lost if its beaches were to disappear... And Waikiki isn’t the only beach that’s going to get smaller: Others expected to experience significant erosion within a century include: Mau’umae and Hapuna on the Big Island; Makena State Park and Ho’okipa on Maui; Hulopo’e on Lanai; Pu’ko’o and Halawa on Molokai; Waimanalo,  Ala Moana on Oahu; and Ke’e beach and Poipu Beach Park on Kauai... According to the report, approximately 90 experts in the field of sea level rise found that it will occur to the tune of 1-3 feet around Hawaii within 85 years.

Tourism isn’t the only industry that will be affected by climate change. The Sea Grant reports say that increases in the ocean’s temperature could affect the feeding habits and migration patterns of big-eye tuna, with catches expected to decrease by as much as 27 percent by 2100.

Dr. Chip Fletcher of the University of Hawaii at Manoa estimates that ocean levels will rise by a little less than an inch a year in Hawaii. While that may seem minor at first, over time the impacts on Hawaii’s environment and, by extension, the tourism industry, could be great.

Higher ocean levels could create more storm surges which could threaten water lines, roads and a majority of the state’s hotels, which are situated along the coast. Linda Cox, a co-author of the report, said that damages from rising sea levels would be the most economically harmful. “My idea is that the coastline infrastructure will be the biggest challenge due to the expense associated with moving or altering it,” said Cox, researcher with College of Tropical Agriculture and Human Resources at UH.
The effects of rising ocean levels can already be seen on Oahu, said Cox.

“We already have major issues in coastal areas — look at Hanalei  and the North Shore of Oahu. When major storm events occur, these communities struggle to keep roads open, necessities in stock and people aware of the action to take,” Cox said...

The article concludes with "What's Being Done," which I can summarize for you in two words: MORE STUDIES. In other words, no action will be taken until there's a major catastrophe. Sigh.

Disconnecting the Dots

There were two articles in today's Honolulu Star-Advertiser (Oct. 21) dealing with unrelated beach and ocean problems that should be connected: regulation of commercial use of  our oceans, and control over what can or cannot be done with our shorelines. But if you read those two stories back-to-back, you'll start to get a headache trying to track all the federal, state and county agencies that have overlapping responsibilities. For instance, who is responsible for addressing beach erosion? Under Hawaii's convoluted system, there is split jurisdiction that is literally based on a shifting high water mark -- and both the State and counties often cite the murky lines of demarcation as excuses to not do anything about the very real threat of rising sea levels and ongoing shoreline management issues.

Ever since I got involved with the public beach access movement a few years ago, I have experienced firsthand the futility of attempting to get State or county action on protecting beach rights of way and doing something about shoreline "creep" by property owners on Oahu, who are rebuilding oceanfront structures closer to the sea (I can't call them "homes" because they look more like mini-hotels). I suggest those"homeowners" (often out-of-state investors) take a good look at what's happening on the North Shore before they decide to spit in Mother Nature's face and erect mansions as close as legally possible to the sea.

Anyhow, in today's beach erosion article about "regulatory woes" the reporter got some good quotes from Dolan Eversole, who works for Sea Grant and has done a lot of studies about erosion and shoreline management options. His suggestion is there should be a single coastal commission. It would have authority over the shoreline and coastal waters, and eliminate split jurisdiction. Makes sense, right? Except the article then goes on to quote various people from the existing agencies/departments that are currently not doing a very good job of addressing longstanding problems, and of course, those people say a coastal commission would be a bad idea because it could add another layer of bureaucracy. Um,  I think they missed the point. THEY are the added layers that need to be streamlined.

Okay, I'm not sure if the reporter phrased the question in the wrong way, or these government employees are simply too dense to understand the concept -- a coastal commission isn't meant to be an "added" layer of anything. It would be done to eliminate or consolidate a myriad of departments, agencies and ad hoc "advisory" groups that have been meeting for years and years, in order to simplify the regulatory process. It would create a single office that looks at the big picture from molasses spills to beach access and whether commercial kayak operations can be allowed on beaches in Hawaii. But if you broach the subject with a government lifer, all they will see is a threat to their individual jobs and benefits. Rarely will you ever hear a government worker admit their job or department does stuff that is redundant or could be eliminated to save taxpayer money, while making things more efficient.

And this is why we wind up with people who distrust government or say they want to dismantle Big Government... until their homes are threatened by beach erosion, commercial development or global climate change, and all of a sudden those same people are squawking that government isn't doing enough. The real problem though, is how government does things. They manage from crisis to crisis, instead of coming up with a long-range plan, then sticking to it.

BTW, in 2009 I asked Rep. Chris Lee to introduce a proposal for a joint State and counties task force to consider creating a Hawaii Coastal Commission. At that time, testifying against the proposal before State representatives was Sam Lemmo (DLNR) and Chip Fletcher, a UH researcher who is quoted as now saying an "overall agency" to take charge of coastal land use should be "studied." Apparently they thought the DLNR was doing just fine on its own. When will all these different factions start connecting the dots, and see that the ocean and beaches need to be treated as Hawaii's most valuable resource -- not as some lines on a map or organizational flow chart to be divvied up among the DLNR, CZM, MACZAC, DPP, EPA, even DOT (yeah, the molasses spill was the Dept. of Transportation's jurisdiction, believe it or not), along with each island's county councils and zoning/planning/parks departments. It's a shame because there are many well-meaning people trying to do their jobs... except they're like a bunch of people on a canoe, each paddling in different directions.

Idiots Building CLOSER to the Ocean

As I predicted a couple of years ago, wealthy buyers of oceanfront property on Kailua Beach were going to use Oahu's lax shoreline setback rules as an opportunity to rebuild closer and closer to the sea in order to "leap-frog" other houses that were being rebuilt by people who don't even live in these ugly box-like mini-hotels. All this while there is growing evidence of climate change and melting glaciers, which is contributing to rising sea levels across the planet.

Don't believe me? I recommend you watch CHASING ICE, a harrowing documentary about a National Geographic photographer who embarked on a difficult mission to photograph what's happening with melting glaciers around the world. Anyone who thought Al Gore was possibly exaggerating the threat in AN INCONVENIENT TRUTH a few years ago should be forced to see this movie. Now. It turns out, no one foresaw that global warming is happening faster than anyone could predict. CHASING ICE is available on Netflix through instant streaming. See it.

Meanwhile, in Kailua Beach the news media has been preoccupied with major beach erosion that has been going on at the south end towards Lanikai. Yes, that's alarming. The causes aren't clear though, and could be part of a natural cycle. However, what has already been documented is the fact that allowing houses or artificial barriers such as sea walls -- or even vegetation -- to encroach on the shoreline, hastens erosion. We've seen it in Kahala Beach and Lanikai. Now property owners are doing the same thing on the north end of Kailua Beach, but the news media ignores it. Why?

Simple reason, really: there's no parking near the only public beach access at that end, so reporters and cameramen would have to hike a fair distance to do a story on it. And since the lack of access results in far fewer beach-goers at that end, there's less attention paid to the ongoing desecration of what used to be a stable shoreline because the older homes were built far back enough to allow the natural sand dunes to adjust to natural changes and conditions.

Here's some photos to show you what's been happening. The first is from a couple of years ago:



See the newer house on the right? It leapfrogged a newly-rebuilt house to the right of it that is pictured below, and cut off the views of the older house on the left with the "For Sale" sign.



Flash forward to the present. Remember that older house with the "For Sale" sign? Well, looks like someone bought it and decided turn-about is fair play! And you can probably guess what will happen next: that house to the left of the older one under construction now, will probably be sold to someone who will rebuild right next to the other two... closer to the ocean.
