A Wall in a River is a Dam
In this week’s Republican debate Bachmann, Cain, and Romney each fought to prove that if elected President they would build longer, taller, and more deadly walls than their opponents. In the run up to the event, Representative Bahmann vowed that the length of her wall “will be every mile, it will be every yard, it will be every foot, it will be every inch of that border.” Not to be outdone, Herman Cain said, “It’s going to be 20 feet high. It’s going to have barbed wire on the top. It’s going to be electrified. And there’s going to be a sign on the other side saying, ‘It will kill you — Warning.’”
In an effort to please politicians by erecting mile after mile of border wall, Customs and Border Protection (CBP) continues to push for new walls in the floodplain between the Rio Grande and the Texas towns of Roma, Rio Grande City, and Los Ebanos. To convince the International Boundary Water Commission (IBWC) to go along, CBP has tried to paper over the risk of increased flooding with more than a million dollars worth of reports and flood models. Walls in the floodplain are likely to either deflect water into Mexican cities or bottle it up in U.S. ones, and so far IBWC has rejected CBP’s claims to the contrary.
Last June CBP paid Baker Engineering for yet another flood model, which was used over the summer to pressure IBWC to reverse its position. The Sierra Club recently received a copy as a result of a Freedom of Information Act request.
The new flood model makes it clear that no changes in the border walls themselves are being considered. The walls’ locations are the same as those mapped out in a Baker report from 2009. They are still designed to split flood waters, diverting a portion of the flow into these three communities. The only difference is that the newer model uses a different computer program, allowing for more detail.
In 2009 CBP did not know what type of border wall they would like to build, so Baker’s model imagined a solid slab. Now CBP says that they plan to use a bollard design, similar to the walls built to the north of the levees in Cameron county. But in Cameron county the levees would keep flood waters away from the border wall, whereas the new walls would be in the floodplain, where there are no levees, and would be inundated if the Rio Grande were swollen by a major flood.
For this report, Baker assumed that debris in the bollards would block no more than 10% - 25% of the water. That led to the conclusion that walls would have minimal impacts. But the assumption that between 75% and 90% of the water in a major flood would pass harmlessly through the wall seems to be based on wishful thinking at best, or a desire to rig the model’s results at worst.
Flooding rivers pick up large amounts of debris, from trash to trees, and carry it along until they encounter an obstruction. Bollards spaced a few inches apart may allow crystal clear water to pass through, but in a flood debris will pile up. As the debris accumulates it blocks more and more water, and the border wall acts more and more like a dam.
This should not be news to CBP. The border walls that they have already built in Arizona, and which they promised would have no impact on flooding, have caused tremendous flood damage.
On July 12, 2008, seasonal monsoon rains swept through northern Mexico and southern Arizona. In the sister cities of Nogales, Sonora and Nogales, Arizona the border wall acted as a dam. In addition to the wall built above ground it was later revealed that DHS had constructed a wall in a storm drain that passes beneath both cities without informing local officials or the International Boundary Water Commission. Water in the storm drain backed up and burst through the roof, adding to the flooding in the streets. Two people drowned, and millions of dollars of damage was sustained by Mexican businesses and residents.
The same storm caused flooding in Organ Pipe Cactus National Monument. CBP had stated categorically that border walls crossing washes in the monument, using a design similar to that proposed for the new South Texas sections, would be water permeable and therefore would not impact flooding. Grate openings 6 inches high and 24 inches wide that were built into the base of the wall were supposed to allow water to pass through, but they quickly became clogged with debris. The wall then acted as a dam, with water piling up behind it 2 to 7 feet deep. Backed up flood waters then traveled along the wall in search of an outlet, which was found at the Lukeville, Arizona port of entry, causing millions of dollars in damage to private and federal property.
Following this event, Baker Engineering was paid to run the length of the border wall from El Paso to San Diego and produce a report on the problems posed by the many walls that cross stream beds and washes. They documented “debris build-up which sometimes reached a height of 6 feet.” Their report concluded that, “fencing obstructs drainage flow every time a wash is crossed. With additional debris build-up, the International Boundary Water Commission’s (IBWC’s) criteria for rise in water surface elevations (set at 6” in rural areas and 3” in urban areas) can quickly be exceeded.”
Flood gates were installed, at a cost of over $24 million, in an attempt to prevent a repeat of the 2008 flooding. These gates are massive, and to work require Border Patrol agents to predict a flood, drive into a wash ahead of the water, throw a cable over a bar at the top of the wall, hook it to the top of the gate, and use their Jeep’s winch to pull the gate up. Then the agents need to get out of the wash and get to high ground. If they are not quick enough, they could be swept away or slammed into the wall by raging flood waters. If they manage to get out of the way they may be forced to wait on high ground between flooded washes until the waters recede.
Last August one of the sections of Arizona border wall that CBP had retrofitted with flood gates was knocked over and washed away by the force of flood waters after just over two inches of rain fell. Debris build-up had again turned the wall into a dam, just as it had in 2008. In this case, instead of following the wall to the nearest port of entry, the debris piled higher and higher the water poured over the top like a waterfall. The falling water tore away the wall’s foundation at the same time as the weight and pressure of the water pushed against the wall with increasing force. A forty-foot wide section of border wall fell.
Border Patrol spokesman Lloyd Easterling blamed the wall’s failure on human error, apparently because agents had not gone into washes ahead of the flash flood to open flood gates.
But the problem does not lie with patrol agents who cannot predict the weather, or don’t want to drive into a riverbed during a flood. The problem is higher up CBP’s command structure, with administrators who are so fixated on building walls, and thereby pleasing their superiors, that they overlook a basic fact:
A wall in a river is a dam.
It is time for Customs and Border Protection to face up to the fact that when they build walls in flood-prone areas, they may be able to ignore the impacts on paper, but not in the real world. The walls that they are pushing in Roma, Rio Grande City, and Los Ebanos will have a disastrous impact on the very homeland that they are supposed to protect. Customs and Border Protection needs to ignore political pressure and give up on these last sections of border wall, before they do any more damage.

City Commissioners Vote to Buy Brownsville a Border Wall
On June 2, the Brownsville City Commission finally capitulated to the Department of Homeland Security’s demand that they give away city property to build the border wall. They had attempted to do this twice before, first last July and again this past February. In both instances the commissioners backed down in the face of widespread opposition from Brownsville residents. This time, however, they stuck with DHS, ignoring the will of the people by voting to give away the city’s land and to commit to build a border wall through Brownsville at the city’s expense. No other city has done so much to help build the border wall.
When the City Commissioners considered this deal last February, they issued a press release praising it, saying that “The City of Brownsville is in the unique position to be the only border city between San Diego, California and the Gulf of Mexico to be offered the ability to remove the federally mandated border fence.” The Commissioners’ spin leaves out the fact that the initial border wall will only be removed after it is replaced with a border wall that will be far more permanent and imposing, and one for which Brownsville taxpayers will foot the entire multi-million dollar bill.
While the contract with DHS has been rewritten, the substance remains the same. The City of Brownsville will give up 15 acres of city property, which DHS valued at $123,100 when it initiated condemnation proceedings last September. The Department of Homeland Security will not pay a dime for the city’s land.
"Floating fence" border wall design in Cameron County, Texas
According to the contract, at some indefinite time in the future, the city will pay to build a levee-border wall in another unspecified location to replace the “floating fence.” It stipulates that the city must pay to buy the land for the new levee-border wall, and “construction shall be the responsibility of Brownsville, and shall not be performed by the United States or at any cost to the United States.” The bids for the levee-border walls in Hidalgo County ranged from $12 to $16 million per mile. Placing cost ahead of confidence in the quality of construction of our flood control levees, Hidalgo naturally went with the low bidder. Assuming that Brownsville does the same, the 2-4 miles of levee-border wall that will slice through the city will cost between $24 and $48 million, every dime of which must come from city coffers.
Levee-border wall under construction in Hidalgo County
Once Brownsville constructs the new levee-border wall, DHS will pay to take down the “floating fence.” Maybe. Homeland Security’s promise to pay to take down the first border wall is “subject to the availability of funding.” If they do not have the cash in hand, “then DHS shall provide Brownsville with appropriate access and authority to remove such sections and dispose of the removed material” at the city’s expense.
One new provision in the contract that the City Commission approved states that, “Brownsville shall, at its sole expense, preserve and maintain the Replacement Border Barrier.” So not only will Brownsville’s taxpayers have to pay to build a levee-border wall that none of them want, they must also pay to maintain it for decades to come.
Of course, it is unlikely that Brownsville will be able to come up with all of this money, so the “temporary” border wall will in fact be permanent.
But if they do, and private developers come through with millions more to build a riverwalk, we can look forward to long lines of tourists waiting to show their passports to go through the border wall to reach the trendy restaurants on the other side. What could be more appealing than fine dining in a no-man’s land that the Department of Homeland Security has walled off to keep “terrorists and terrorist weapons” from entering the rest of the United States?
Levee-border wall at the Old Hidalgo Pumphouse World Birding Center in Hidalgo County
Even if everything goes as the City Commission hopes, this deal defies all logic. It is as if someone took away your home, and rather than fight in court to either stop them or force them to pay you its market value of $123,100, you offered to buy them new land and build them a new house that would cost anywhere from $24 to $48 million, and you would then pay to maintain it. Accepting such a deal would certainly put you in a “unique position.”Yet, this is the deal that Brownsville City Commissioners Anthony Troiani, Edward Camarillo, Ricardo Longoria, and Leo Garza voted to accept. Charlie Atkinson, who is a Border Patrol employee, abstained. Commissioner Carlos Cisneros and Mayor Pat Ahumada voted to reject it.
When public funds are used to build schools, hospitals, or other structures for the benefit of taxpayers, the politicians who approved the project can be counted on attend a ribbon-cutting ceremony and place a plaque telling future generations of their accomplishment. If the City of Brownsville manages to pull funds from schools, hospitals, or other projects to build the levee-border wall, I trust that the City Commissioners who voted for it will be on hand for the dedication ceremony. They can smile and wave and shake hands with the grateful residents of Brownsville, who will sleep better knowing that the border is no longer broken, that floods of terrorists no longer wash over Brownsville, and that it was their City Commission that brought about this shining moment. Engraved on a bronze plaque that will be bolted to the concrete slab of the border wall will be the names:

Hidalgo County's Border Wall is Nothing to Brag About
Last March, Hidalgo County Judge JD Salinas cut a deal with Department of Homeland Security Secretary Michael Chertoff to build part of the border wall. Rather than build the wall to the north of the levee, DHS would insert it into the levees in Hidalgo County. It was estimated that this would raise the per-mile cost from $3 million to $5 million, so the county agreed to pay $44 million. When the bids came in, the low bids were $12 million per mile. As a result of Judge Salinas' capitulation Hidalgo County's border walls are nearly finished, while neighboring Starr County's wall construction has not begun, and Cameron County's is just beginning. They still have the chance to fight to halt construction, while for Hidalgo County the fight moves from stopping the wall entirely to preventing pro-wall zealots from filling in the spaces between levee-walls.
In his recent State of the County address, Judge JD Salinas made statements regarding the levee-border wall that were, to put it charitably, less than honest.
Judge Salinas said,
"The levee-barrier, which was the alternative reached by the Hidalgo County Drainage District and the U.S. Department of Homeland Security, is now 95 percent complete. This solution has saved residents and businesses from purchasing $150 million per year in mandatory flood insurance. It has prevented private land from being taken by the federal government, and the flood control structure is more environmentally-sensitive than the proposed border fence."
As to his first point regarding the money saved by residents who will not need to purchase flood insurance, the levee-border wall did not replace all of the levee sections in Hidalgo County that were deemed inadequate. In a number of instances, portions of our levees that were not in need of repair were ripped apart to insert border walls. Other sections that are still in bad shape were not touched by the levee-border wall scheme. This is because the locations of levee-border walls had nothing to do with
Luckily for
As for the idea that the levee-border wall is better for the environment than Homeland Security’s original border wall designs, Judge Salinas knows full well that the opposite is true. Last March the US Fish and Wildlife Service (USFW) wrote a letter to the Department of Homeland Security in response to the plan to build levee-border walls in
“This combined project would eliminate wildlife passage by replacing CBP’s original “wildlife friendly” fence design with an impermeable 16 to 18 foot high wall built into a flood control levee. This new project design would effectively eliminate the wildlife passage component of the earlier design and would impair the ability of the wildlife corridor to fulfill its function. […] We would like to document that any proposed fence and/or levee segment that bisects lands within the Lower Rio Grande Valley National Wildlife Refuge cannot be found compatible with the purposes for which the Refuge was established.”
Today the levee-border walls in
In contrast to Judge Salinas’ claims of environmental benefit, former Secretary of Homeland Security Michael Chertoff knew that the levee-border wall would violate numerous environmental laws. Last April he used the Real ID Act to issue 2 waivers of federal laws, one of which was specifically for the

While on the surface his State of the County address is the run-of-the-mill self-congratulation that we expect from a politician, in fact his words have real consequences. Following his capitulation to former Secretary Chertoff, Judge Salinas went from being an opponent of the wall to the Department of Homeland Security’s poster boy. In press releases and Congressional testimony they use him to show that they are working with local stakeholders, rather than ignoring local concerns, condemning private and municipal property, and irreparably damaging border communities, economies, and ecosystems. Judge Salinas’ words provide DHS with cover as they continue to strong arm our next-door neighbors in
Of course it is naïve to expect a politician to own up to his mistakes, to admit to being suckered into a bad deal that has cost his constituents millions of dollars. It is unrealistic to expect a mea culpa from Judge Salinas. But if he truly cares about the residents of

Obama needs to consign Border Wall plan to the trashcan of bad ideas
In one recent article, I expressed my concerns that the initiation of Border Wall construction in Hidalgo County, Texas during the middle of the 2008 hurricane season was inherently dangerous and could predispose our region to massive flooding if we were impacted by a major storm while such construction was in progress.
In response to my article, an unknown person (hereafter referred to “Anonymous”) posted the following statement on the No Border Wall blog on Sept. 22, 2008:

Levee / border wall diagram from the Marfa Sector draft Environmental Assessment
The engineering details of the Border Wall provided by “Anonymous” are informative but irrelevant. How effective the Border Wall might be as a flood-control structure once construction is complete has nothing to do with the concerns expressed in my article – the real question is how it may be expected to perform if we are impacted by a major tropical storm or hurricane while construction is in progress.
All phases of Border Wall construction were in progress by September 7, 2008, the beginning of the week in which Hurricane Ike entered the Gulf of Mexico and intensified into one of the largest and most dangerous storms in Texas Gulf Coast history.
This included extensive excavation of the south levee face, the embedding of pilings and metal panels along the top of the levee, and construction of the partially-completed concrete wall which now extended approximately 150 to 200 meters west of its original point of origin.

To suggest that a levee in this condition is storm-worthy and capable of withstanding the onslaught of floodwaters produced by major tropical storms and hurricanes is ludicrous. Tropical storms and hurricanes are typically associated with high winds and torrential rainfall, which generally result in deep water and strong water currents within floodways. Any engineer or hydrologist worthy of the name should recognize that strong water currents developing in this manner will almost certainly obliterate any type of obstruction (earthen or otherwise) causing abrupt changes in surface contour of levee faces.
Moreover, a competent engineer should also recognize that the five- to six-meter “gap behind the wall” provides a means to generate very powerful water currents if any type of breach were to occur in the levee behind the concrete wall, e.g., as a result of overtopping. This is a simple matter of physical principles and hydrology – if a breach in this area should occur, floodwaters under tremendous pressure will tend to flow along the “path of least resistance,” i.e., they will flow through the breach until the system stabilizes as floodwaters subside.
Levee / border wall construction in Granjeno, TX 11/27/08
Since the concrete wall is impermeable to water, it will force floodwaters to enter a restricted channel (i.e., the gap in question) and to flow with increased velocity toward the breach in a direction parallel to the face of the destabilized earthen levee. As water flows through the breach, hydraulic action (erosion caused by moving water) will tend to widen the breach, which in turn will allow more water to enter the restricted channel (gap) which in turn will tend to increase the velocity of water flowing through the channel.
Despite repeated advisories from NOAA that water temperatures in the Gulf of Mexico were highly conducive to the development of tropical storms and hurricanes, Border Wall construction proceeded at a feverish pace without interruption during the peak of the 2008 hurricane season – August and September. During the second week of September, when Hurricane Ike was on an apparent “collision course” with south Texas, one of our local officials stated somewhat arrogantly that construction of the Border Wall (referred to as “levee repairs”) might be “halted temporarily” if Hurricane Ike headed our way. As it turned out, no such delay occurred – during the latter half of the week, Hurricane Ike began to veer northward and made landfall at Galveston on Sept. 13.
Levee / border wall construction behind homes in Granjeno, TX August 1, 2008
It is important for the reader to note that officials of the Department of Homeland Security, our local county officials and their construction contractors made no apparent preparations at Granjeno and three other construction sites in Hidalgo County for the possible landfall of Hurricane Ike along the south Texas coast. On Sept. 13, the day in which Ike was devastating much of southeast Texas and western Louisiana with massive flooding, construction of the Border Wall at Granjeno and three other sites in Hidalgo County was in high gear, with fleets of cranes, backhoes and other heavy equipment gnawing away at our flood-control levees like huge metallic termites.
The determination by DHS and our county officials to meet “Bush’s deadline” at essentially any cost and/or risk was presumably based on the erroneous logic that if funding for legitimate levee repairs and upgrades is not obtained now (under the Bush administration), it will be very difficult or impossible to obtain in the future (under a new presidential administration). This urgency is somewhat understandable considering the recent findings by FEMA that many areas of the LRGV levee system are not in compliance with federal standards, and will not be recertified unless they are upgraded and brought into compliance with FEMA standards within a period of one year (an additional one-year extension was recently granted).
Regardless of what their motives may have been, however, the decision by DHS and our local officials to initiate Border Wall construction in the Lower Rio Grande Valley during middle of the 2008 hurricane season, and their failure to make adequate preparations for the possible landfall of dangerous storms such as Hurricane Ike (which at one time seemed imminent) is inexcusable and placed the properties and lives of hundreds and possibly thousands of our citizens at considerable risk. We were very fortunate that Hurricane Dolly made landfall before Border Wall construction began in earnest at Granjeno and the other three sites, and that Hurricane Ike veered northward two days before its destructive landfall at Galveston. Had Hurricane Ike maintained its westward course and impacted the LRGV region while large sections of our flood-control system were under major construction, this story would not have ended happily (for us, at least). We cannot afford to allow this to happen again – ever!
Within the next six weeks, the George Bush administration will be history and Barack Obama will be inaugurated as the 44th President of the United States. If our country reenters a period of normalcy and rational thinking, the “Great Texas Border Wall” will hopefully be committed to its rightful place in the “Historical Trashcan of Bad Ideas.” Given our staggering federal deficit – which has increased substantially following the recent $750 billion bailout of the U. S. financial industry – it is very unlikely that the federal government will continue to pour millions (or billions) of dollars into a concrete structure that has become symbolic of tyranny and is despised almost universally by residents along the U.S.–Mexico border.
Levee / border wall construction in the Lower Rio Grande Valley National Wildlife Refuge 11/27/08
Termination of the Border Wall concept would place great pressure on the U.S. Congress to develop real solutions to the problem of illegal immigration (instead of expensive and dangerous concrete placebos) and would allow available funds - including the $400 million “bailout package” for the ailing Border Wall project – to be used much more effectively for repair and upgrades of the Lower Rio Grande Valley levee system and bring it into compliance with FEMA standards for the first time in many years. Of all the options available to us right now, this comes closest to being a true “win–win” situation, and is the only one which will really protect us from disastrous flooding if and when we are impacted by some future storm similar to Hurricane Ike.
We were deprived of these basic rights during 2008 because of two federal laws – the Secure Fence Act and the Real ID Act - which were enacted by the U. S. Congress during a period of national hysteria, fear and intolerance. Collectively, these two laws allowed federal, state and local officials involved in the Border Wall project to conduct their business in a reckless and dangerous manner, and deprived the nearly two million American citizens in the Lower Rio Grande Valley of their legal rights to challenge construction of the Border Wall on any virtually any grounds, including public safety issues.
What happened in south Texas during 2008 is a prime example of what happens when too few people are given too much power without an adequate system of checks and balances. In order to ensure that this never happens again, it is imperative that all residents of our border regions with Mexico (and hopefully, all Americans in general) demand that our elected congressional representatives either amend or repeal both of these dangerous laws at the earliest opportunity. The next congressional session would be none too soon.

Testimony on the Environmental Impacts of the Border Wall Given to the Texas State Legislature
A number of members of the No Border Wall Coalition spoke at the hearing, addressing the impacts of the wall on agriculture, border communities, and the waiving of laws under the Real ID Act. Martin Hagne, Executive Director of the Valley Nature Center and a founding member of the Coalition, described to the legislators the effects that the walls currently under construction are likely to have on the environment.
Here is his testimony:
Thank you for allowing us the opportunity to testify and to give you further information about the border wall in Texas as designed by the U.S. Department of Homeland Security. My name is Martin Hagne, and I am the Executive Director of the Valley Nature Center in Weslaco, Texas. Today I am representing the No Border Wall Coalition, which was formed in the Lower Rio Grande Valley in May of 2007. And although the No Border Wall Coalition is greatly concerned with all aspects of the border wall, including human rights, immigration, property rights, and economic issues, today my testimony will focus on the impact of the wall to wildlife and the environment.
The border wall is to date the single most detrimental environmental disaster to take place along the Texas Mexico Border in our lifetime. The environmental effects will be far-reaching, long-lasting, and permanent in many areas. There is simply no way to construct such a barrier in such a place without doing irreparable harm to wildlife and the very sensitive habitats along the Rio Grande.
Today I will focus mostly on the Lower Rio Grande, but all areas in Texas slated for the border wall face similarly destructive challenges. Obviously the habitats along such a long border will vary greatly, but the damage will be equally destructive.
Habitat Loss
The easiest issues to describe will be the obvious habitat loss that will occur when the concrete and steel structure is built. As mandated in the Secure Fence Act of 2006, the wall is not just a single wall but two structures spaced apart to facilitate high speed roads between and outside the walls. This in itself will clear a wide swath of habitat up to 350 feet. Granted that DHS seems to be pursuing a single layer wall at this time, but the Act still stipulates the double layered version and still shows such on the "books." We must, therefore, be aware of this and act accordingly.
The thin layer of riparian forest that still exists along the Rio Grande, is often only 100 feet wide or less. Agricultural land has crept up all the way to the rivers edge in many places. The riparian forest made up of tall woody species such as Anacua, Texas Ebony, Rio Grande Hackberry, and Mexican Ash has been slipping away due to clearing for human use, and much of what little is left has been altered due to the river being dammed in 1957 by Falcon Dam. The dams and reservoirs that make the Valley flood-free and inhabitable for humans have also stopped the seasonal flooding which keeps the riparian forests alive. Each year floods would inundate the lowlands of the Rio Grande and keep such ecosystems thriving. Flood control is altering these precious forests into drier thorn forests.
For over 30 years efforts have been made to reclaim some of the lost habitat along the river and to create a Wildlife Corridor. US Fish & Wildlife, along with many other groups, such as Texas Parks & Wildlife, The Nature Conservancy, and Audubon Society, to name a few, have been working hard to purchase old farmland and to re-vegetate them back into a natural state of riparian forest. So far over $70 million has been spent of mostly federal funds to purchase land, and about $30 million has been used to plant native plants on these tracts. Tens of thousands of school children have taken part in these planting efforts! Now we are faced with all that work and taxpayer's money being bulldozed.
It has been argued by proponents of the wall that such small areas needing to be cleared are insignificant and that birds can fly over any structure that is put in their path. While it is true that birds can find water by flying a distance, mammals and reptiles will not be able to travel over such a structure. It has also been said that birds can leave an area and adapt to another habitat.
But there are bird species that rely on certain habitats that can't adapt fast enough if their present homes are removed. These are species that live and nest in this riparian habitat that is almost gone and that has little left of its original make-up. These same species are not found north of the Rio Grande Valley, and many are just found along the actual Rio Grande itself. These birds are limited to the riparian remnants along the river.
In these tall, Spanish moss-draped forests we find such bird species as Gray Hawk, Tropical Parula, Clay-colored Robin, Northern Beardless-Tyrannulet, Brown Jay, Muscovy Duck, Common Black-Hawk, and Red-billed Pigeon. These birds rely on the riparian forest along the river, and many rarely stray inland. These birds do rarely if ever utilize other habitats and could therefore be extirpated from Texas and the United States.
It has been estimated, using the maps released for this EIS, that over 80% of USF&W refuge property will be affected along the Rio Grande in the Lower Rio Grande Valley.
This does not include the several Texas Parks & Wildlife's Wildlife Management Areas and privately owned sanctuaries by such groups as the National Audubon and The Nature Conservancy located along the river that will be affected. The Lower Rio Grande Valley National Refuge alone in the Lower Rio Grande Valley takes into account eleven (11) different biotic communities. This is arguably the most bio-diverse region in the U.S.
Habitat Fragmentation
Equally destructive to wildlife is habitat fragmentation. A few decades ago this was rarely thought of as a problem. Roads were built crisscrossing our nation's wildlife refuges and wildlands. But now biologists know the very real threat of fragmenting any habitat. The edges created invite new species of plants and animals, changing the make-up of the ecosystem, often driving out the original inhabitants.
Not only does fragmentation affect the habitat in question, but it also has far-reaching effects on entire ecosystems. By changing the makeup of one area, it also affects other neighboring habitats and in the long run changes the entire regional ecosystem. This has not been taken into account in any DHS document or "study" released so far.
The other effect the wall will have is separating animals from each other on both sides of the wall. Ground dwelling mammals, reptiles, amphibians, and other wildlife will not be able to cross 16 to 18 foot tall concrete and steel structure. This will leave them not able to reach water, nor roosting and nesting sites.
Species can become genetically flawed by being cut off from neighboring populations, eventually creating a bottle-neck effect in the gene pool. It has been said that the wall can't cut off species from reaching each other because it is an east and west directed wall. This is not true, as DHS maps shows it clearly meanders south and north and doubles back in many places. Most animal species when faced with such an obstacle cannot and will not find ways around it, leaving them confused and stuck in place. This has already been documented in Arizona, where the wall was built through wildlife refuges.
The Wildlife Corridor was designed for just such travel and will now be severely hampered and made ineffective.
Endangered Species
There are 20 species of federally endangered species in this area, as well as many more threatened and endangered species listed by the state of Texas. The border wall will affect many of these species in negative ways through habitat loss, habitat fragmentation, corridor loss, water being cut off, and loss of eco-tourism dollars that positively help habitat restoration efforts.
Two federally endangered wildcat species are barely hanging on in existence within their U.S. range in the Lower Rio Grande Valley: the Ocelot and the Jaguarundi. The corridor is a must for these species to be able to travel to new territories for mates. As the efforts to restore the populations of these cats succeed, new territories need to be found by males to further the populations. Crossing the Rio Grande into Mexico will be a must for these cats. The border wall will cut off their access to such crossings. These cats will not, and cannot, travel long distances to find "openings" in a wall. Their habitats are now too fragmented to allow for this. Without new genetic populations to breed to, the U.S. population will become in-bred, narrowing its lines, until it can no longer get out of a bottleneck in its genetics. USF&W and other organizations such as Environmental Defense have been working with private landowners and ranchers in deep South Texas to create more habitats for these cats, especially the Ocelot. Land corridors for travel north and south are also being pursued, as this is critical for the cats to reach Mexico. The wall in Cameron County will basically stop this project.
The USFW plan for recovery for the Jaguar was already shelved because of the negative impacts the wall will have in Arizona. If the Jaguar cannot freely travel north and south, it has no chance of recovery in the U.S., leaving the program totally ineffective.
The Wildlife Corridor in the Lower Rio Grande Valley is also a must for other species in peril of extirpation. Long-tailed Weasels, the Mexican sub-species of American Beaver, and others, live in the riparian areas along the Rio Grande. These species, as well as the hundreds of others, must be taken into account.
Wetland Loss and Water Quality Issues
Critical wetlands along the wall will be affected, many of which are ephemeral (drying out during dry seasons). Due to flood control measures, the area in question has lost much of the seasonal wetlands that used to exist. Any and all wetlands removed or negatively affected therefore have an even higher negative impact to area wildlife.
The fact that many of these wetlands are seasonal makes it even harder to identify them, therefore making it easy for DHS to say none existed.
With the removal of any wetlands comes degraded water quality. Wetlands act as natural water cleansers as the water filters though wetland aquatic vegetation. Farm chemicals and other harmful runoff from city lawns and streets have no natural filtration system before reaching the Rio Grande.
Flooding is also negated by natural wetlands. Ponds and marshes slow the rain waters and collect large amounts of flood water.
Flood Levee System and Wall Combo
Last year FEMA announced that the flood levees which are built, maintained and operated by the federal agency IBWC, were not high enough to protect the area from a major hurricane. The area would no longer be certified and, therefore, insurance would go up or be unattainable. Industry would pull out and many other issues would arise. Although this should be a federal issue and fixed by federal dollars and agencies, it has now become a County project. Hidalgo County was "frightened" into signing a deal with DHS to receive some federal funds and then use County bond funds to repair the levees. But under one condition: that the face of the levee be an 18 foot sheer concrete wall that would also act as a border wall.
This scenario has many flaws. First, the County should not have to pay for such repairs. Second, the 22 miles of sections repaired are only in the areas where DHS wanted a wall in the first place, leaving unrepaired gaps in the flood control system. This does nothing for making the system FEMA approved again. Thirdly, cutting into the side of the existing levees during hurricane season is nothing short of asking for a disaster. Fourthly, fixing the levees on the U.S. side at this time will endanger hundreds of thousands of lives on the Mexican side of the border if levees are not simultaneously repaired in Mexico.
And lastly, this levee/wall combo has been touted as a win-win for the environment. Although the levee/wall combo might affect certain areas less as far as habitat removal, it will only slightly improve on that situation. But what it will do is become a solid 18 foot wall of concrete which is totally impenetrable to wildlife. There will be effectively no movement over, under or around this wall. No animal, besides a bird, could get over such a structure. It is less wildlife friendly than the originally designed wall.
Environmental Law and Justice
The Real Id Act of 2005 was passed to give the Minster of Homeland Security broad sweeping powers to secure the nation. It, unprecedented, gave Michael Chertoff powers to waive any and all U.S. laws to build the wall. This was not a well known law by lawmakers and many voted on this passage without knowing enough about it.
This year alone DHS has waived 36 federal and state laws ranging from the Clean Water Act to the Endangered Species Act. Such powers have only if ever been enacted during acts of war towards the United States.
Environmental organizations as well as individuals have tried to sue DHS to stop the wall, to retain their property and not allow the government to take it, but all legal action is made void due to the Real ID Act. The people of the United States have no legal recourse.
The Texas Park & Wildlife Department has already lost land on their Las Palomas Wildlife Management Tracts. A levee/wall combination is dissecting properties owned by TPW and USFW in an area that was before only dissected by a dirt levee which was traversable by wildlife.
The same Act also has rendered the National Environmental Policy Act (NEPA) void and, therefore, no Environmental Impact Studies (EIS) were needed to be performed. DHS started the NEPA process and eventually did release an EIS document. This 600 some page document was nothing more than a glorious work of copied material taken out of a dictionary. The studies for such an elaborate project should have taken over two years, but instead the document was published in months! Environmental studies on wildlife migration, daily usage, breeding and nesting sites, plant surveys, use during inclement weather, and many other such long-term studies could not be produced in months. The document was the worst example of government bullying.
The Real ID Act must be repealed!
The "fact" being put forth by DHS and BP representatives that a border wall is less environmentally intrusive than the "trash and human waste" left by immigrants is truly such a far-fetched illusion that we cannot believe it has even been brought up! A habitat left with trash and waste is far better than a habitat void of plants. Plants make the habitat. An area with native plants gives life whether it is degraded with trash or not. Trash can be removed, while permanent environmental damage by clear-cutting cannot! These are such simple facts that it is unbelievable that any government agency would state otherwise!
An animal living in the Rio Grande Valley within a riparian area is not one that is much impacted by trash and human waste. Such a statement shows ignorance and lack of understanding of the area's fauna and flora, this fact further showing the true need for a broader and much more thorough EIS. We are not talking about whales swallowing plastic bags. Ocelots do not eat trash! On the other hand, if you remove any habitat from the area which is already in such short supply, you are likely to lose species.
To compare the need for a border wall for national security to the needs of conserving a lizard, as DHS spokespersons have done, we can only say that if DHS believes this wall will only impact one lizard, a complete and broader EIS would show just how wrong such a statement is.
Environmental Economic Issues
Many areas along the Texas-Mexico border have prime natural areas. The Big Bend area in West Texas has tens of thousands of wild areas, river canoe excursions and hiking opportunities.
The Lower Rio Grande Valley is the top bird watching and nature watching destination in the U.S. The Valley is considered the most biologically diverse area within the U.S. 517 bird species have been recorded in this small area. That is more than all other state totals besides Texas, California, Arizona and New Mexico. Native plant species number at least 1,100, but if all forbs and grasses were counted, these numbers could easily be closer to 3,000. Over 340 species of butterflies are found here, as well as over 120 species of odonates. There are 80 some species of mammals, and a higher number of reptiles and amphibians. These numbers are staggering for such a small area.
The wall is not only a disaster to our environment, but also a disaster to the local economy, which embraces eco-tourism as an annual income of $125 million, contributed by some 200,000 nature visitors annually. An ecological impact of the wall is the fact that the bird species that depend on this habitat will disappear! That in itself is truly disturbing. The implication the wall has for humans is not only the loss of nature, but the loss of livelihoods. No bird watcher would want to come see a steel and concrete wall where before a native habitat stood.
Other nations have already figured that out! Below is a note from a bird watcher from Sweden who visited the Valley and Santa Ana NWR last year.
"Thanks very much for sending me information about the horrible plans for the Rio Grande; I am reading it with great interest. I just want to say that it is not only an interior matter but also an international one. It would hit the birding business coming from other countries. I mean, if the nice areas around the Rio Grande would disappear, not many birders from others countries will go to Texas in the future, as well as people from other places in the USA. Hopefully there will be a better solution than destroying a unique fauna." Christer Landgren, Sweden
The State of Texas has invested millions of dollars into the three State Parks in the Lower Rio Garden Valley. The fairly new World Birding Center complex with nine (9) sites is also a partnership with the state. Many of these sites, along with the above mentioned USFW refuges, Audubon Sabal Palms Sanctuary, the TNC Southmost Preserve, the NABA Butterfly Park, and others, will be negatively affected.
The National Audubon Society is presently debating what to do with their flagship sanctuary, Sabal Palms. After the wall goes up it will be walled off, and concerns are many. How will staff have access? Who will have keys? What if a fire breaks loose? Will anyone insure us? Do we dare to allow visitors? etc. None of these questions can be answered by DHS when asked.
National organizations such as NAS and TNC are now faced with possibly giving up decade-old work and investments and pulling up stakes from the Valley, taking with them resources and funds.
With these funds also goes many environmental and science funded programs for local school classes. In a day where children need every opportunity to get outdoors to exercise and learn about nature, we will be forced to lose such precious resources.

The No Border Wall Coalition Praises DHS’ Decision to Spare 3 South Texas Communities
The border wall has already led to the condemnation of farmland and municipal property, and the walls that are currently under construction are devastating wildlife refuges and destabilizing South Texas’ flood control levees. $3 billion has been wasted on walls that the Border Patrol says only slow crossers by a few minutes. With two wars, a deepening financial crisis, and trillions of dollars of debt, our nation cannot afford to throw more money into this bottomless pit.
Levee - border wall construction on the northern border of a US Fish and Wildlife Refuge tract in South Texas October 24, 2008
We hope that the decision to spare these communities signals the beginning of a sane border policy on the part of the Department of Homeland Security and the Bush administration. The border wall is nothing more than a political prop, a backdrop for politicians who want to look tough on national security. With the election behind us, it is time to move beyond hollow symbols.
The No Border Wall coalition calls upon President-elect Obama to appoint a new Secretary of Homeland Security who will reject Michael Chertoff’s failures and refuse to play politics with the lives and property of border residents. He should enact a moratorium on further border wall construction until a non-partisan organization such as the Government Accountability Office can review both the impacts of the walls that have already been built and the foreseeable impacts of proposed walls.

Texas Politicians Ignoring the Danger that the Border Wall Poses to South Texas' Levees
During the past year, many of us have submitted letters to our elected representatives expressing our concerns regarding the manner in which the Border Wall or Fence is being constructed in the Lower Rio Grande Valley (LRGV). Most of our letters of concern have gone unanswered although we have received a few vague responses which appear to be standard form letters which have little or no relevance to the concerns we expressed. This indicates to us that our letters are not getting past your staffers, so we are expressing these concerns again by way of this Open Letter to Texas Politicians, which includes all of our Senators and Representatives in the U. S. Congress, the Governor of Texas, and our local County officials involved in the Border Wall project.
One of the primary concerns expressed in our previous letters relates to the fact that construction of the Border Wall in Hidalgo County was originally scheduled to begin on 25 July 2008 – a date which lies in the middle of our annual hurricane season. Less than one week after letters requesting a congressional investigation or reevaluation of the Border Wall project in south Texas were sent to Mr. Richard Stana of the Government Accountability Office in Washington (with copies to both Texas Senators), the LRGV region was impacted by Hurricane Dolly, a category 2 storm which made landfall on 23 July and caused extensive flooding in most of Cameron County and within large areas of central Hidalgo County. Approximately two days after the landfall of Hurricane Dolly, and while Dolly’s floodwaters were still rising in most areas of the LRGV region, DHS contractors began excavating the flood-control levees at Granjeno for implantation of the concrete Border Wall. Since that time, additional large-scale construction projects have been initiated along levee systems located east of Santa Ana NWR near Alamo and south of Donna and Weslaco. It does not seem to have dawned on any of the decision-makers in the Border Wall project that we are still in the middle of our annual hurricane season, and they seem to be oblivious to the fact that NOAA has warned that 2008 will probably be an unusually active hurricane season.
To appreciate why we are so concerned about this situation, please note the images of the flood-control levees at Granjeno (located four miles south of Mission) which were acquired on 1 September 2008 – the same day that Hurricane Gustav made landfall on the Louisiana coast. The first two images were taken from the back yard of a local resident and show the north face of a levee under construction – notice how loose and friable the soil on this side of the levee appears to be, which suggests that it has been destabilized to a considerable extent as a result of construction activities.


In a meeting held in Edinburg during early-June of this year, our local Hidalgo County officials assured us that construction of the Border Wall will not destabilize our flood-control levees in any manner - they even stated that levees under construction would be checked and certified as being stable (at least 15 of our members were present at this meeting and can verify that these statements were made). Ladies and Gentlemen – Senators, Representatives, Governor, and Locals - it does not take a rocket scientist or a hydrologist or a civil engineer to figure out that the “flood-control” levees shown in the above images are in a highly destabilized condition as a result of Border Wall construction and will probably not hold up to runoff produced by a heavy afternoon thundershower, much less to floodwaters produced by a major tropical storm or hurricane. This is a very dangerous situation – we have already been impacted by one hurricane this season and recent NOAA satellite images of the Atlantic, Caribbean and Gulf of Mexico resemble an “assembly line” of tropical storms and hurricanes, any one of which could head our way. If this occurs, we will have a week at most to prepare for it, and we see no way that destabilized “Humpty-Dumpty” levees such as those that now occur at Granjeno and other areas can be “put back together again” in time to avert major flooding.
We support efforts to secure the international border with Mexico, but we also expect and demand that government programs in our area be conducted in a manner that does not place our homes and lives at undue risk.
Thank you.
