Flood control measures encourage settling too close and provoke severe flooding events

Flood control to keep water out of houses seems like a good idea, but it turns out that it causes the flood control measures to keep needing to be raised higher, and it encourages people to build too close to flooding areas, plus “rare and catastrophic events take place”. Like the 2009 “700 year flood” and the four or more floods this year that have overflowed the Withlacoochee Wastewater Treatment Plant. In our case, there are also the issues of widespread clearcutting and buildings and streets with impervious cover. The local runoff containment requirements in the various local government zoning codes may be like levees: “flood control structures might even increase flood risk as protection from frequent flooding reduces perceptions of risk”.

This encourages human settlements in floodplain areas, which are then vulnerable to high-consequence and low-probability events.
Much simpler just not to give out building permits for flood zones. Or we could put medical buildings right next to a creek, assuming because it’s never flooded it never will….

Moody can’t get onto site for Moody Family Housing –Michael Noll @ LCC 2013-08-27

Dr. Michael G. Noll of VSU said representatives of Moody Air Force Base for the second time could not get permission to go on the site for the Moody Family Housing the Commission approved rezoning for two weeks before, at the 27 August 2013 Regular Session of the Lowndes County Commission.

He also handed the Commission and interested parties copies of a public comment he and VSU professors Don Thieme and Can Denizman had sent to USAF. Michael G. Noll handouts Plus the developer still refused to provide a copy of the geotechnical report the Air Force’s Environmental Assessment says the developer is required to send to the Air Force.

If there is nothing to hide, if there are no problems with possible developments of the area, why not share the report?

Two different people report seeing Commissioner Richard Raines catch Dr. Noll on the way out of the building and ask him what would be involved in doing the geophysical survey Dr. Noll has repeatedly asked to do.

Karst subsidence beneath a house in Lowndes County –Don Thieme @ LCC 2013-08-13

Received yesterday on Florida sinkholes spreading real estate effects in same Aquifer as under Lowndes County. -jsq

Scanning John — Thank you for pressing forward on this important issue for the airmen and their families at Moody AFB as well as for all citizens of Lowndes County. My colleagues and I are also concerned and hope that we can eventually obtain the Phase I geotechnical study. Of course, we have our own research agendas as well as a desire to see our students working on these problems close to their own university campus. In particular, one of my undergraduate students just completed his thesis on karst subsidence beneath a house in Lowndes County. Here is a link to a poster where he presented those finding to our undergraduate research conference: GPR Investigation of Subsidence.

Harris nuke flaw “fixed” that wasn’t found for a year

Less than 500 miles from here in NC, what else haven’t they found if ‘Duke Energy’s examination a year ago “was supposed to have found that problem then and fixed it”‘? This was a ‘a quarter-inch spot the NRC and the company describe as a “flaw” in the reactor vessel head, which contains heat and pressure produced by the nuclear core’s energy.’ When a solar panel has a quarter-inch flaw, you get a tiny percentage less electricity, not the risk of radiation leak or worse. Would you rather have two more nukes at the same site, run by the same company that can’t run the one it’s got safely, or solar power instead?

Plus where is the advantage of baseload capacity when Harris 1 has only been up 27.41% for the past month (NRC data), which is hardly better than the approximately 20% sun hours per day for solar power in North Carolina this time of year. Given the low and continually-dropping cost of solar panels, Duke could simply over-provision distributed solar panels and get way more than 20% or 27.41% effective power, and get that on budget and on time.

Harris 1 7% last 27.41% for the month

Sinkhole costs, and prevention vs. reaction

The day after the VDT ran Lowndes County’s admission that the sewer line break was theirs, not Valdosta’s, did the VDT start a series of financial investigation like they did about Valdosta’s water issues? Nope, they ran a piece about how much weather costs the county, with no recognition of watershed-wide issues, nor of any need for the county to participate in proactively dealing with them, to reduce costs, for better quality of life, to attract the kinds of businesses we claim we want. Nope, none of that.

Jason Schaefer wrote for the VDT 27 April 2013, What natural events cost Lowndes taxpayers,

In the Deep South, near a river plain where floodwaters rise and ebb from season to season and wetlands that distinguish the region from anywhere else in the nation, flooding makes a significant portion of the concern for Lowndes County emergency management.

OK, that’s close to getting at some of the basic issues. We’re all in the same watershed, and we need to act like it instead of every developer and every local government clearcutting and paving as if water didn’t run downhill. Does the story talk about that? After all, the county chairman attended the 11 April 2013 watershed-wide flooding meeting that led to the city of Valdosta’s likely participation in flodoplain planning. Nope; according to the VDT, everybody around here seems to be hapless victims of weather:

Believe So. Cal. Edison about San Onofre?

Should we believe the operator of the broken San Onofre 2 nuclear plant that it’s safe to restart at 70% power? The same operator that knew the now-broken steam generators were flawed before it installed them? Recommended by the same NRC staff who couldn’t answer opponents’ questions? The same NRC that doesn’t publish licensee documents and says that’s never been a practice?

SanDiego6.com wrote yesterday, Sen. Boxer Blasts Report on San Onofre Nuclear Generating Station,

On Monday, Southern California Edison announced it had formalized a request to amend its operating license to allow it to operate its Unit 2 reactor at 70 percent beginning June 1.

The reactor was undergoing scheduled maintenance in January 2012 when a small, non-injury leak was discovered in plant’s other reactor. The plant has been shut down since.

According to Edison, vibrations that led to premature wearing of steam pressure tubes in the reactors don’t occur at 70 percent power. The utility wants to operate on limited power for the five warm weather months and then shut down for an inspection of the tubes.

After the inspection, the reactor would resume operating at 70 percent power. The company said it would use the collected tube data to determine an appropriate power setting for the long term.

There’s the catch:

Circular wastewater firing squad continues

The VDT's Sunday front page was covered with wastewater stories, continuing the circular firing squad of the local powers that be. Meanwhile in Dublin, GA, they're breaking ground for solar panels at the local high school, using a bond financing model that we could use here, if local leaders would look up.

In addition to some detail about the city's FEMA application and following up on flooded yards, the VDT followed up on its EPD and EPA scrutiny story with one saying City received help from EPD to keep EPA away. It's good the VDT is covering these issues, but it's still leaving out important parts of the local water story.

Apparently firing back at Thursday's Valdosta City Council session, perhaps especially Robert Yost's very pointed criticisms of the VDT, the VDT concluded its rather rich Sunday editoral:

City leaders, please, no more of the blame game. The citizens of this community are imploring you to just accept responsibility and fix it.

Yet the VDT has spent the last week blaming the city, and has accepted no responsibility for its own role, or that of its editor, Kay Harris, in the recent loss of the SPLOST referendum that would have further funded wastewater work in Valdosta.

Now, I agree with the VDT that Continue reading →

Fracking north Georgia

Fracking, coming to north Georgia soon.

Dan Chapman wrote for the AJC Sunday, Gas drillers turn to Georgia

Conasauga Field DALTON, Ga. — Trillions of cubic feet of natural gas believed to lie below the hills of northwest Georgia have remained virtually untouched and unwanted — until now.

Shale gas drilling is slowing across the country, but a handful of companies are poking around this corner of the state looking for the next natural gas “play.” If they succeed, Georgia could join the ranks of states reaping jobs, revenue and fears of environmental damage from energy production, The Atlanta Journal-Constitution has learned….

In Alabama, the Conasauga shale field contains 625 trillion cubic feet of gas, according to Bill Thomas, a geologist who taught at the University of Kentucky and Georgia State. A similar amount could be underground in Northwest Georgia, he added.

Wish I didn’t have to say I told you so: Fracking: coming soon to a state near you? 26 Dec 2012.

No fracking. No nuclear. No biomass. Let’s get on with solar and wind.

Nuclear is over —Jeremy Rifkin

Economist, author, and advisor to governments Jeremy Rifkin told an agent of the world's largest uranium field operator at a conference of global investors that there's no business future in nuclear power.

Jeremy Rifkin answered a question at the Wermuth Asset Management 5th Annual Investors Event 26 September 2012, Nuclear Power is Dead,

I don't spend much time on nuclear technology, unless somebody asks me about it, because frankly from a business perspective, I think it's over….

Here's the video, followed by more transcript and discussion.

Nuclear power was pretty well dead in the water in the 1980s after Three Mile Island and Chernobyl. It had a comeback. The comeback was the industry said "we are part of the solution for climate change because we don't emit CO2 with nuclear; it's polluting, but there's no CO2".

Here's the issue though,

Let the Sun Shine: Fact versus Fiction —Michael G. Noll

LTE in the VDT today. I’ve added a few links. -jsq

Fox News recently claimed that “solar won’t work in America because it’s not as sunny as Germany”. Such statements are common for a network that has long lost its credibility. Unfortunately too many take such gibberish at face value. Thus columns like “environmentalism or obstructionism?” are not surprising, but in the end it’s the facts that matter:

  • Global warming is real. For years we have been experiencing record heat waves, droughts, wild fires, etc., and while seawater levels are rising, storms like hurricane Sandy become major threats to low lying areas along coast lines.
  • The main culprit for global warming are greenhouse gases like carbon dioxide, resulting from the burning of fossil fuels, especially coal and oil.
  • While China overall emits more than we do, the US leads in per capita emissions. The average US citizen produces three times more carbon dioxide than the average Chinese citizen.
