Water Bridge in Germany

Even after you see it, it is still hard to believe ! Water Bridge in Germany.... What a feat! Six years, 500 million euros, 918 meters long.......now this is engineering! This is a channel-bridge over the River Elbe and joins the former East and West Germany, as part of the unification project. It is located in the city of Magdeburg, near Berlin.

The photo was taken on the day of inauguration. To those who appreciate engineering projects, here's a puzzle for you armchair engineers and physicists. Did that bridge have to be designed
to withstand the additional weight of ship and barge traffic, or just the weight of the water?

Answer:

It only needs to be designed to withstand the weight of the water!
Why? A ship always displaces an amount of water that weighs the
same as the ship, regardless of how heavily a ship may be loaded.

This is from Wikipedia:

The 918-metre Magdeburg Water Bridge or Wasserstrassenkreuz in German, (52.231, 11.701), completed in October 2003, connects two important German shipping canals, the Elbe-Havel Canal and the Mittellandkanal, which leads to the country’s industrial Ruhr Valley heartland. Engineers first conceived of joining the two waterways as far back as 1919 and by 1938 (longer ago than the Beach redevelopment idea!) the Rothensee lock and bridge anchors were in place but construction was postponed during the first and second world wars. After the Cold War split Germany, the project was put on hold indefinitely by the East German government. With the reunification of Germany and the following establishment of major projects in transport tracks the Water Bridge again became a priority. Construction began in 1997 and after six years and around half a billion euros the gigantic water bridge now connects Berlin’s inland harbour with the ports along the Rhine river. The huge tub created to transport ships over the Elbe took 24,000 metric tons of steel and 68,000 cubic meters of concrete to build. Until the opening of the water bridge in October 2003 the ships moving between the Midland canal and the Elbe-Havel canal had to detour 12 km through the Rothensee lock, the Elbe and the Niegripp lock.
Below is an aerial of the area. The water bridge is the northern one. You can see a traditional highway bridge to the south:

Article on "Takings" Lawsuit in Hollywood, Florida






I am tidying up my e-mails this weekend and am finding some interesting items. This article appeared during the middle of 2006. Not sure of the status of the lawsuit, but it is an example of the type of claim that can be made citing the Bert J. Harris Act. These are the types of waters we will be navigating during our review of the Comprehensive Plan and Zoning Code changes that we will be considering as the year progresses.

I'll attempt to find out what happened and if there have been any other claims.

Reflections on Hurricane Katrina

A new volume of essays edited by Carol De Vita, Senior Research Associate, After Katrina: Shared Challenges for Rebuilding Communities zeros in on recovery efforts in the Gulf Coast region and underscores lessons for rebuilding after future disasters. To be sure, there are signs of progress, but the volume notes that basic infrastructures that can attract and retain residents are still missing. By the start of 2007, only about half of the public schools in New Orleans were open, 30 percent of the childcare centers had returned, and just 17 percent of the buses in the city were back in operation. The volume includes essays on affordable housing, helping children and families rebuild their lives, arts and culture, public and environmental health concerns, rebuilding assets, and preparing for the next disaster.

Other publications in the After Katrina Series include: A collection of essays on ";Charities' Response to Disasters: Expectations and Realities" in which the authors discuss the strengths and weaknesses of charities' respones to the Gulf Coast hurricanes, lessons learned from previous disasters- the September 11th attacks and the Asian Tsunami- and how well those lessons were applied.
Also, an annotated bibliography
The Urban Institute and the Louisiana Association of Nonprofit Organizations organized a national roundtable in Washington to hone in on the policy issues related to the rebuilding of New Orleans. The March 19 policy roundtable hosted by the Urban Institute featured about 40 experts from a wide range of groups tied to disaster response: federal, state, and local offices, practitioners and advocacy groups. The keynote speech was by Walter Isaacson, president of the Aspen Institute and vice-chairman of the Louisiana Recovery Authority. Isaacson challenged nonprofits to step up to the plate to do more to help rebuild New Orleans and\n shape the future of the Gulf Coast region. \

Water Restrictions



Below is is an informative post made by Walter Baker on the Lake Worth Talk discussion board. While I was walking my dogs yesterday, I witnessed many people with even addresses hand watering and washing their cars - right time of day, but wrong day - only those with odd address numbers should have been doing those activities. I expect this drought will be getting worse and the more we follow the guidelines now, the better it will be for all of us in the long term. Please make sure that your neighbors know what the rules are for use of sprinklers and hand watering!

Now that a Phase II water shortage has been declared, and in concert with Lake Worth Resolution No. 60-2005, anyone using more than the base equivalent service unit (ESU) of 5,000 gallons of water a month will incur a 30% surcharge to their water bill beginning with bills rendered on May 1, 2007.

Ordinance No. 2007-21, adopted by the City Commission on April 3, 2007 provides for certain penalties to individuals and business who do not abide by the mandatory restrictions set forth by the SFWMD. Violators will incur the following penalties:
  • First Violation: Warning or $25 fine

  • Second Violation: $50

  • Third Violation: $100

  • Fourth Violation: $500 (criminal offense)

  • Residents and Businesses with Odd Number Addresses - Wednesday and Saturday 4:00 a.m. – 8:00 a.m. with Irrigation System5:00 p.m. – 7:00 p.m. for Hand Watering

  • Residents and Businesses with Even Number Addresses Thursday, and Sunday 4:00 a.m. – 8:00 a.m. with Irrigation System5:00 p.m. – 7:00 p.m. for Hand Watering

  • In the event SFWMD declares a Phase III water shortage, further restrictions will be issued and customers who consume more than the base ESU of 5,000 gallons per month will incur a 45% surcharge to their water bill. Residents and local businesses are urged to conserve!

  • To report a water restriction violation, contact the Lake Worth Police Department at 561-586-1611 and select option #2. DO NOT call 911.

The following is a news release from their website:

No quick end to drought in sight Lake Okeechobee keeps dropping as South Florida Water Management District works to stretch limited water supply

Mussel shells seem out of place alongside desert-like cracks in a dry landscape, but the mismatched combination is what's found on Lake Okeechobee shores as drought grips South Florida. "Statewide, Florida is experiencing one of its driest seasons on record since 1895, and it's possible that the summer rainy season won't bring enough water to end the drought," said Ben Nelson, state meteorologist with the Florida Division of Emergency Management. "Our main concern is that we'll have a La Niña develop this summer in the equatorial Pacific," Nelson said. "La Niña typically means drought in Florida."

Nelson issued the weather warning at a press conference held with South Florida Water Management District officials at Jaycee Park Pier in the Lake Okeechobee Recreation Area on Tuesday.With the drought already one year old, a La Niña system could prolong it through the end of 2007.

A La Niña occurs when cooler than average waters are recorded in equatorial Pacific waters. This shifts the jet stream northward, preventing storm systems and rain from impacting Florida in the fall, winter and spring, said Nelson. Even if Florida receives average rainfall this summer, that won't be enough to break the drought if the wet months are followed by unseasonably dry weather. In the last 18 months, South Florida has received just 49.31 inches of rain, almost 17 inches less than the 30-year average of expected rainfall."

It is critical that South Floridians follow the water restrictions so that enough of the limited natural resource is available for drinking water and environmental needs," said Chip Merriam, Deputy Executive Director at the South Florida Water Management District. Florida last experienced a multi-year drought in 1999-2001. Lake Okeechobee water levels dropped to a record low of 8.97 feet in May 2001. Tuesday, the lake level was 9.66, less than one foot from that record low. The current drought is hitting South Florida harder than 1999-2001 drought, because rainfall has been scant statewide.

During the last drought, rainfall in Central Florida was enough to carry South Florida through the lean times. Water flowing from the Kissimmee River Valley helped to recharge water supplies in Lake Okeechobee. With statewide rainfall shortages for much of 2006, there isn't enough water in Central Florida to help alleviate drought here. The result is a strain on water supplies from surface sources like Lake Okeechobee, rivers and canals, and South Florida’s shallow aquifer. Lake Okeechobee is low enough that the U.S. Army Corps of Engineers hasn't ordered major water releases since January 2006.

The most recent pulse environmental releases ran from only December 2006 to February 2007.

Effects of the drought are most visible around Lake Okeechobee, from vibrant green grass growing in canals where water once flowed, to channel markers that appear to have sprouted on land. The district has also closed four navigation locks to boaters because the low water levels are a hazard. "There is a silver lining in the drought for Lake Okeechobee's wildlife and vegetation," said Susan Gray, Deputy Department Director for Watershed Management. "Low lake levels are giving beneficial submerged and emergent plant species a chance to re-grow, and water managers may now have the opportunity to remove some of the phosphorus-laden muck from the lake bed."

Neat Links - America's Favorite Architecture and Blueprint for America

I wanted to get this up right away as I just stumbled on it through my gmail account. I will offer more commentary on it tonight. The excerpt below is from the Google Blog (yes, they have one of their own). Check out the "America's Favorite Architecture" site, but as it relates to Lake Worth - the Blueprint of America link has some great information on other communities and how they do Master Planning and use some tools provided by Google (Google Earth and Sketch-up) as tools in the process.

More later, gotta get back to work now.

New 3-D layers from AIA on Google Earth
Tuesday, April 24, 2007 at 6:23:00 AM Posted by RK Stewart, FAIA, President 2007, American Institute of ArchitectsArchitects are pretty passionate about architecture -– no surprise there. However, we've come to find that the American public is too. Starting today, there are two new Google Earth layers with which to explore architecture’s most popular structures and take away some ideas to help enhance the communities we live in. As president of The American Institute of Architects (AIA), I’m ecstatic to announce our partnership with Google Earth to launch these new layers in celebration of our the 150th anniversary.Check out this video on YouTube to watch us navigate these layers from Google headquarters.Fly to America’s Favorite Architecture, a layer featuring the American public’s favorite architecture (as selected though a national poll announced earlier this year). View all 150 structures, including many with just created 3-D models of the buildings, ballparks, bridges, and memorials that characterize architecture in the eyes of Americans. And then explore the second layer, Blueprint for America. Blueprint is a community service effort funded by the AIA, in which AIA members donating their time and expertise are collaborating with community leaders and local citizens to enhance the quality of life in their community. You’ll be able to track the progress of these projects on Google Earth as they unfold over the next year and, we hope, become inspired to take action where you live.
