Organ Pipe Cactus National Monument Damaged by Border Wall Flood Obstruction

New Park Service Report Details Environmental, Infrastructure Damage Caused by Predictable Border Wall Flood Problems.

The following press release comes from the Center for Biological Diversity, regarding the impact of the border wall on flooding in Organ Pipe National Monument on July 12. The same storm system that caused flooding in Nogales, Sonora, Mexico, which was dramatically worsened by the presence of the border wall that runs through the sister cities of Nogales as well as an illegally built wall in the storm sewer beneath the cities, was responsible for the flooding of the washes in Organ Pipe. This is a regular occurrence that the Department of Homeland Security had been warned of, but apparently Chertoff did not heed those warnings.

PHOENIX— A newly obtained National Park Service report details ecological and infrastructure damage in Organ Pipe Cactus National Monument caused by flood obstruction and debris accumulation along recently constructed portions of the border wall. Damage includes severe erosion, infrastructure damage, and movement of floodwaters and drainages behind debris obstructions into adjacent deserts and, in one case, through a border-crossing station.

An environmental analysis conducted by the Department of Homeland Security in 2007 concluded that the fence would “…not impede the natural flow of water.” It would be “…designed and constructed to ensure proper conveyance of floodwaters and to eliminate the potential to cause backwater flooding on either side of the U.S.-Mexico border.” Further, Customs and Border Protection would “…remove debris from the fence within washes/arroyos immediately after rain events to ensure that no backwater flooding occurs.” Homeland Security Secretary Michael Chertoff has since exempted the border wall from all environmental laws.

“The callousness displayed by Homeland Security in ignoring warnings to damage a national treasure is mind-boggling,” said Robin Silver of the Center for Biological Diversity. “The border wall does not stop humans, but it will stop jaguars and other wildlife. It is already wreaking havoc on the southern part of Organ Pipe National Monument.”

“The contrast between the report findings and the environmental assessment displays the Bush administration’s wholly meaningless approach to environmental analysis,” said Silver. “The administration essentially did no analysis at all.”

The Park Service report shows several instances in which debris collected in flash floods in south-flowing drainages caused natural resource and infrastructure damage and states that National Monument resources and infrastructure will continue to be impacted, as well as resources and infrastructure on neighboring lands in the United States and Mexico. The report anticipates the following short- and long-term impacts:

Accelerated scour below the pedestrian fence will damage the structural integrity of the vehicle barrier along the U.S./Mexico boundary unless continued maintenance occurs.

Floodwaters will flow laterally along the pedestrian fence and on the patrol road. These flows will result in erosion and scour above and below the foundation wall of the fence, including areas hundreds of feet outside existing drainage channels. As a consequence, the need for routine maintenance and repairs of the patrol road and vehicle barrier will increase.

The patrol road associated with the pedestrian fence will change vegetation in Organ Pipe by changing rainfall retention or runoff along the northern road edge.

Riparian vegetation will change in response to increased sedimentation.

Channel morphology and floodplain function will change over time.

Channelized waters will begin a gullying process that has the potential to transform land surfaces in the affected watersheds.

“While the Bush administration may claim it’s taking environmental impacts of the border wall into consideration, building wire mesh fences across washes prone to debris-laden floods is fundamentally flawed,” said Silver. “It’s time for Homeland Security to lift its embargo on environmental laws. The border fence does not stop humans. Now we have more proof of the wall’s destruction of our national treasures."

Action Alert - Public Comments on the Border Wall in Buenos Aires National Wildlife Refuge

Bulldozers are already clearing vegetation to build the seven mile long section of border wall on either side of the Sasabe, Arizona port of entry (see below). The Department of Homeland Security prepared an Environmental Assessment (not to be confused with the more stringent and comprehensive Environmental Impact Statement that should be completed for a project in sensitive habitat) which, not surprisingly, found that construction of the wall would have “no significant impact.” To date Secretary Chertoff has not issued a Real ID waiver of environmental laws, so DHS cannot legally ignore the Endangered Species Act, the National Environmental Policy Act, and other relevant statutes.


Part of the Sasabe border wall will be built on the southern edge of the Buenos Aires National Wildlife Refuge. The Refuge is currently working to determine whether or not a 15 foot tall steel wall is compatible with its mission, and has opened a brief public comment period. It is important that anyone who is concerned about the environmental impacts that the border wall will have take advantage of this opportunity and write a letter.

According to the draft Compatibility Determination,

The Refuge was established on August 1, 1985 “....to conserve (A) fish or wildlife which are listed as endangered species or threatened species .... or (B) plants ....” 16 U.S.C. 1534 (Endangered Species Act of 1973) and for the “...development, advancement, management, conservation, and protection of fish and wildlife resources....” 16 U.S.C. 742f(a)(4) (Fish and Wildlife Act of 1956). Congressional records and other pertinent files show that conservation of the masked bobwhite quail was the major impetus behind establishment of the Buenos Aires NWR. Habitat restoration and the existence of a self-sustaining population of masked bobwhite quail remains a primary goal of the Refuge.

In total this portion of the border wall will clear 51 acres of habitat, and will be an impassible barrier for large terrestrial animals such as pronghorn and jaguar. In the last few years jaguar have been photographed in southern Arizona, giving hope that they may be able to move back into their former U.S. range. While according to the Border Patrol a border wall will only slow a human crosser by 5 minutes, a jaguar will find it impossible to climb over a 15 foot high steel wall.


Unfortunately, the draft Compatibility Determination finds construction of the wall to be compatible with the refuge’s mission. In many places it simply repeats assertions from the Environmental Assessment. These include the statement that “Jaguars will still be able to move through other areas of the border,” which conveniently ignores the fact that most of the Arizona border will be walled off, not just the Buenos Aires National Wildlife Refuge. It is important that this flawed argument be pointed out in public comments, along with the basic incompatibility of a wall in a wildlife refuge. The Compatibility Determination and the Environmental Assessment that it is based upon focus narrowly on the footprint of the wall, ignoring the fragmentation of habitat that extends beyond the refuge’s borders. The refuge is not an island, it is a portion of a larger ecosystem, and the ability of animals to travel through that ecosystem is vital to its continued viability.

The public comment period on the Buenos Aires National Refuge’s draft Compatibility Determination closes on September 18. It is crucial that we all take advantage of the opportunity to comment on its inadequacies and flawed determination. Comments must be sent to:
