Border Residents Kept in the Dark about New Border Walls

by Scott Nicol

Four members of the Senate’s “Gang of Eight,” the group charged with crafting comprehensive immigration reform legislation, recently paid a visit to the border wall that separates Nogales, Arizona from Nogales, Sonora.

The trip was little more than a photo-op.  The senators did not meet with locals or hear from others who live on the border, who experience border security daily and will be directly impacted by any border security measures in the coming bill.  But their pilgrimage to the wall did send a message that their bill is likely to be heavy on enforcement, possibly including hundreds of miles of new border walls.

Senator McCain (R-AZ) led the tour, and he chose a striking location to give Senator Schumer (D-NY) his first glimpse of the border wall. 

Maybe he just wanted to show off the nearby section of wall that he used as a backdrop for his “Complete the Danged Fence” campaign ad. 

 

It is a safe bet that he did not take his colleagues to the spot, a few hundred yards from where they posed for the press, where last October a Border Patrol agent reached through the wall to shoot an unarmed teenager in Mexico 11 times in the back.  He probably also failed to point out the high water mark left on Mexican buildings when, in 2008, the Nogales border wall dammed floodwaters, causing millions of dollars in property damage and the drowning of two men.
 

Of course those events don’t fit the simple narrative of McCain’s “perfect plan” for border security that he outlined in his TV ad.  Better to stare into the camera and ignore inconvenient facts, then and now.

Senator Schumer likely sees more “danged fence” as the cost of immigration reform, the burden that border communities will have to bear to bring undocumented immigrants out of the shadows.  That was also the idea in 2006, when the Congressional push for immigration reform fell apart and all we were left with was the Secure Fence Act and hundreds of miles of border wall.

As the “Gang of Eight” has been horse-trading behind closed doors Customs and Border Protection has been quietly laying the groundwork for the last of the Secure Fence Act’s walls to go up in Roma, Rio Grande City, and Los Ebanos, along with neighboring farms and the Lower Rio Grande Valley National Wildlife Refuge.

Customs and Border Protection wants to build these walls in the floodplain, but over the years the International Boundary and Water Commission repeatedly rejected them, citing “substantial increases in water surface elevations and deflections of flow at several points of all three projects.”  Were the Rio Grande to flood after a hurricane or tropical depression, as it did in 2010, walls in the floodplain would deflect water into Mexican cities like Ciudad Aleman, and would stop water from draining out of communities such as Rio Grande City. 

 

Last year, after sustained pressure from Customs and Border Protection, the US section of the International Boundary and Water Commission reversed its decision, rejecting the Mexican section’s objections and allowing these dangerous walls to go forward.  They now officially accept the claim that the border wall will allow flood water to pass harmlessly through, even though in 2008 they forced Customs and Border Protection to build walls in Cameron County of the exact same design north of the levees so that they would be out of the floodplain. 

Homes and businesses, farms and wildlife refuges, could be washed away or inundated by floodwaters as a direct result of these walls. 

Customs and Border Protection says that everything will be fine.  Of course they also said that they would pay to mitigate the damage that previous wall construction inflicted upon the Lower Rio Grande Valley National Wildlife refuge, but after years of promises not a penny has been provided.

Just like the “Gang of Eight” on their trip to Nogales, Customs and Border Protection has made no attempt to talk to residents or local officials in the Texas communities that the new walls will tear through. 

I contacted Customs and Border Protection last week and asked for an update regarding the Starr county walls.  Daniel Tirado, with the RGV Sector Public Affairs Office, responded that, "the Office of Border Patrol identified these segments as highest operational priorities in Texas. Though construction of these segments has been delayed, Border Patrol’s requirement remains.”

The assertion that these walls, or any border walls for that matter, are a high operational priority is absurd.  Customs and Border Protection knows better than to think that border walls stop anyone. 

While the Senators were doing their press junket in Nogales they watched as a woman laid a ladder against the 18-foot wall and quickly climbed over.  Senator McCain even tweeted about it as it happened.
 

Visiting Arizona last summer I easily climbed the border wall in the San Pedro Riparian National Conservation Area.  I was wearing sandals and didn’t have a ladder, but it only took a few seconds to reach the top.  The San Pedro wall is identical to the ones planned for Roma, Rio Grande City, and Los Ebanos.
 

These new walls will go up in Representative Cuellar’s district, and his silence regarding them has been even more striking, and surprising, than Customs and Border Protection’s.  He has not held any town hall meetings to get feedback from, or provide information to, effected communities, and he has not publicly criticized Customs and Border Protection’s plans or their refusal to speak with local residents.

When I asked his office if he had taken any action on behalf of his constituents, he responded,

“I initiated a formal inquiry with CBP as a follow up and update on the status of the proposed fence. CBP has advised that there are no plans for building additional fences in FY 2013 due to the lack of funding.”

Customs and Border Protection also told me that, “Construction activities will commence at such time as funds become available.”

Which sounds good.  Until Congress provides funds for border walls maybe residents can relax.  One might expect that with the sequester gutting the budgets of federal agencies and forcing furloughs from the Environmental Protection Agency to air traffic controllers money for border walls won’t come any time soon.

But tucked into the spending bill that Congress just passed to keep the government running is a provision that says, 

“For expenses for border security fencing, infrastructure, and technology, $324,099,000, to remain available until September 30, 2015.”

Existing border walls are very expensive to maintain, so not all of that money is available to build new ones.  But Customs and Border Protection condemned the land and bought the steel for these walls years ago.  All that is left is to hire the crews, gas up the bulldozers, and start tearing up the land.

And if the “Gang of Eight” includes hundreds of miles of new border walls in comprehensive immigration reform, instead of passing a clean bill that focuses strictly on immigration instead of multi-million dollar handouts to government contractors, the rest of the border landowners and wildlife refuge tracts in Congressman Cuellar’s district will likely suffer the same fate as Roma, Rio Grande City, and Los Ebanos.

Will Walls Worsen Rio Grande Flooding? U.S. IBWC Can’t Give a Straight Answer

By Scott Nicol

The United States section of the International Boundary and Water Commission (US IBWC) recently hosted a meeting in Rio Grande City to explain their decision to allow Customs and Border Protection to build new border walls in the Rio Grande floodplain.  While they should be commended for reaching out to local residents, they seemed completely unprepared, unable to answer the most basic questions about their decision or the new walls.

When, for example, landowners asked whether there had been any on-the-ground surveys, and what the wall would mean for access and impacts to their property, they got no response. 

The manager for Rio Grande City’s international bridge and port of entry asked how they would be able to access the riverbank to carry out ongoing erosion control efforts.  US IBWC did not know. 

Residents asked whether walls crossing the washes that feed into the Rio Grande might become blocked with debris, preventing normal drainage and causing flooding.  At that point US IBWC admitted that even though they approved these new walls months ago, Customs and Border Protection still has not provided them with the walls’ design specifications, so they could not answer that question either.

US IBWC was also unable, or unwilling, to answer a key question about the flood model that they are using to justify their approval of border walls in the floodplain. 

Using the Freedom of Information Act the Sierra Club has gotten a copy of the flood model, as well as a number of related documents.

In 2011 Customs and Border Protection paid Baker Engineering to produce a model that claimed that flood water would pass harmlessly through the 4-inch wide spaces between the border wall’s six-inch wide bollard posts.  Baker’s accompanying report stated that, “A debris blockage of 10% was adopted where the fence is aligned parallel to the flow and 25% at locations where the fence is aligned perpendicular to the flow.”

The model’s computer program cannot add to this number, cannot decide that it is too low and that in reality more debris will clog the spaces between bollards.  By telling the computer that 75% to 90% of floodwater will pass through the wall, Baker effectively predetermined the model’s end result.    

At the meeting in Rio Grande City, surrounded by residents whose lands and lives will depend on whether or not these walls will actually let water pass through or will dam it up, US IBWC could not explain where the suspiciously round and suspiciously low estimate of 10% - 25% debris blockage came from.

In earlier reports Baker Engineering came to a very different conclusion about how much debris border walls were likely to catch.

After border walls in Arizona became clogged with debris and acted as dams in 2008, inflicting millions of dollars of damage on both sides of the border and causing two deaths, Baker Engineering was hired to follow the wall from El Paso to San Diego and report back to Customs and Border Protection.  Baker found that, “PF 225 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.” The report included photographs of bollard-style walls nearly identical to those planned for the Rio Grande floodplain filled with debris, and documented “debris build-up which sometimes reached a height of 6 feet.”

In examining on-the-ground evidence of debris clogging border walls, it bolstered a 2008 Baker Engineering white paper that looked at the likely impacts of the walls planned for Roma, Rio Grande City, and Los Ebanos.  In discussing the wall’s transfer capacity - the ability of water to pass between the bollards - it stated that,

“The transfer capacity estimate has been shown to include a significant allowance for “clogging” due to the accumulation of debris.  In the case of fence segments O-1 [Roma] and O-2 [Rio Grande City], the transfer capacity was estimated to allow for a minimum of 85% and 67% clogging, respectively.  For fence segment O-3 [Los Ebanos], a minimum allowance of 36% was estimated.  It is important to keep in mind that these estimates apply to portions of the fence that are generally parallel to the direction of flow.  Areas that are oriented generally perpendicular to the direction of flow should (for reasons of prudence) be modeled as completely blocked, primarily due to the hydraulic effects of bollards themselves.”

So how did Baker’s estimates of clogging drop from 85%, 67%, and 36% down to 10% where the wall is parallel to the Rio Grande, and from 100% down to 25% where it is perpendicular?

The US IBWC has yet to give the public an answer to that question.

The new flood model, with its low debris estimate, is cited by the US section of the International Boundary and Water Commission as the basis for its decision to allow these border walls.  The Mexican section has rejected the model’s assumptions, countering in late 2011 that these walls would likely obstruct 60% - 70% of flood flows even before the clogging effect of debris is factored in. 

On February 9, 2012 the two sections of the bi-national organization met to discuss their disagreement.  Meeting notes written by the same US IBWC engineer who was unable to answer questions about the model’s assumptions at the Rio Grande City public meeting say that,

“It was recognized that the Mexican Section may prefer a higher percent debris blockage.  It was explained that the U.S. Department of Homeland Security (DHS) wanted minimum debris blockage and a percentage that was felt to be reasonable was agreed upon in the meeting on February 23, 2011, during which the modeling methodology was finalized between USIBWC, DHS, the U.S. Army Corps of Engineers and Michael Baker Jr., Inc.”

So even when they met with their Mexican counterparts, US IBWC gave no concrete evidence that the lower estimate was more accurate than the earlier, much higher one.  The nice, round, low number was \simply “felt to be reasonable”, despite conflicting with empirical evidence from Arizona, and was adopted because it matched up with the Department of Homeland Security’s desire for a model showing a “minimum debris blockage.”

Not only was Mexico’s estimate ignored, they were not even invited to participate in the 2011 modeling methodology meeting.  And six days after the 2012 meeting the US section, flouting its treaty obligations, unilaterally approved Customs and Border Protection’s request to build walls in the floodplain.

Customs and Border Protection (CBP) has not hosted a public meeting on border walls in South Texas since 2007, but they did send a representative to the recent Rio Grande City meeting.  He declined to present any information, and remained silent unless he was asked a direct question. 

When asked when CBP would begin construction he said that at this time they do not have the funds to build these walls.  He failed to mention that CBP bought the steel years ago and currently has it in storage.  More importantly, he failed to mention that the new fiscal year for federal agencies begins on October 1, at which time their bank accounts will be refilled. 

If border residents want answers, we need to demand them now. 

Representative Cuellar and Senators Hutchison and Cornyn need to pressure the US IBWC to reverse its bad decision, and direct Customs and Border Protection to finally give up on these dangerous walls.  They need to take concrete action, and they need to do it now.

But of course they won’t, unless we, their constituents and voters, tell them to.

October is only three weeks away.  The clock is ticking.
