General impact on illegal immigration

96.6% of apprehensions by the Border Patrol in 2010 occurred at the southwest border. The number of Border Patrol apprehensions declined 61% from 1,189,000 in 2005 to 723,840 in 2008 to 463,000 in 2010. The decrease in apprehensions may be due to a number of factors including changes in U.S. economic conditions and border enforcement efforts. Border apprehensions in 2010 were at their lowest level since 1972.

. As of August 29, 2008, the U.S. Department of Homeland Security had built 190 miles (305.8 km) of pedestrian border fence and 154.3 miles (248.3 km) of vehicle border fence, for a total of 344.3 miles (554.1 km) of fence. The completed fence is mainly in New Mexico, Arizona, and California, with construction under way in Texas.

U.S. Customs and Border Protection reported that it had more than 580 miles (933.4 km) of fence in place by the second week of January, 2009. Work is still under way on fence segments in Texas and on the Border Infrastructure System in California.

The border fence is not one continuous structure and is actually a grouping of short physical walls that stop and start, secured in between with "virtual fence" which includes a system of sensors and cameras monitored by Border Patrol Agents.

There have been around 5,000 migrant deaths along the Mexico-U.S. border in the last thirteen years, according to a document created by the Human Rights National Commission of Mexico, also signed by the American Civil Liberties Union Between 43 and 61 people died trying to cross the Sonoran Desert during that same time period; three times that of the same period the previous year. In October 2004 the Border Patrol announced that 325 people had died crossing the entire border during the previous 12 months. Between 1998 and 2004, 1,954 persons are officially reported to have died along the US-Mexico border. Since 2004, the bodies of 1086 migrants have been recovered in the southern Arizona desert.

U.S. Border Patrol Tucson Sector reported on Oct. 15, 2008 that its agents were able to save 443 undocumented immigrants from certain death after being abandoned by their smugglers, during FY 2008, while reducing the number of deaths by 17 percent from 202 in FY 2007 to 167 in FY 2008. Without the efforts of these agents, hundreds more could have died in the deserts of Arizona. According to the same sector, border enhancements like the wall have allowed the Tucson Sector agents to reduce the number of apprehensions at the borders by 16 percent compared with fiscal year 2007.

, proposed a plan to the House on November 3, 2005 calling for the construction of a reinforced fence along the entire United States – Mexican border. This would also include a 100 yards (91.4 m) border zone on the U.S. side. On December 15, 2005, Congressman Hunter's amendment to the Border Protection, Anti-terrorism, and Illegal Immigration Control Act of 2005 (H.R. 4437) passed in the House. This plan calls for mandatory fencing along 698 miles (1,123 km) of the Mexican border. On May 17, 2006 the U.S. Senate proposed with Comprehensive Immigration Reform Act of 2006 (S. 2611) what could be 370 miles (595.5 km) of triple layered-fencing and a vehicle fence.

. The signing of the bill comes right after a CNN poll shows us that most Americans "prefer the idea of more Border Patrol agents to a 700-mile (1,125-kilometer) fence." There is a down payment of $1.2 billion to the Department of Homeland Security marked for border security, but not specifically for the border fence.

As of January 2010, the fence project has been completed from San Diego, California to Yuma, Arizona. From there it continues into Texas and consists of a fence that is 21 feet (6.4 m) tall and 6 feet (1.8 m) deep in the ground, cemented in a 3 foot (0.9144 m)-wide trench with 5000 psi concrete. There were no fatalities during construction, but there were 4 serious injuries with multiple aggressions against building crews, there was one reported shooting with no injury to a crew member in Mexicali region. All fence sections are south of the all American canals, and have access roads giving border guards the ability to reach any point easily, including the dunes area where a border agent was killed 3 years before and is now sealed off.

The obelisks were moved southward approximately 20 meters, onto the property of private landowners in Sonora, as part of the larger project of installing the 18 feet (5.5 m) steel barrier wall.

In August, 2008, UT-Brownsville reached an agreement with the U.S. Department of Homeland Security for the university to construct a portion of the fence across and adjacent to its property. The final agreement, which was filed in federal court on Aug. 5 and formally signed by the Texas Southmost College Board of Trustees later that day, ended all court proceedings between UTB/TSC and DHS. On August 20, 2008, the university sent out a request for bids for the construction of a 10 feet (3 m) high barrier that incorporates technology security for its segment of the border fence project. The southern perimeter of the UTB/TSC campus will be part of a laboratory for testing new security technology and infrastructure combinations. The border fence segment on the UTB campus was substantially complete by December, 2008.

Construction of two of the Hidalgo County fence segments are under way; five more segments are scheduled to be built during the fall of 2008; the Hidalgo County section of the border fence will constitute 22 miles (35.4 km) of combined fence and levee.

Mexico

Mexico has urged the US to alter its plans for expanded fences along their shared border, saying they would damage the environment and harm wildlife.

In June 2007, it was announced that a section of the barrier had been mistakenly built from 1 to 6 feet (1.8 m) inside Mexican territory. This will necessitate the section being moved at an estimated cost of over US$3 million.

.

U.S. Customs and Border Protection (CBP) conducted environmental reviews of each pedestrian and vehicle fence segment covered by the waiver, and published the results of this analysis in Environmental Stewardship Plans (ESPs). Although not required by the waiver, CBP has conducted the same level of environmental analysis (in the ESPs) that would have been performed before the waiver (in the “normal” NEPA process) to evaluate potential impacts to sensitive resources in the areas where fence is being constructed.

ESPs completed by CBP contain extremely limited surveys of local wildlife. For example, the ESP for border fence built in the Del Rio Sector included a single survey for wildlife completed in November, 2007, and only "3 invertebrates, 1 reptile species, 2 amphibian species, 1 mammal
species, and 21 bird species were recorded." The ESPs then dismiss the potential for most adverse affects on wildlife, based on sweeping generalizations and without any quantitative analysis of the risks posed by border barriers. Approximately 461 acres of vegetation will be cleared along the impact corridor. From the Rio Grande Valley ESP: "The impact corridor avoids known locations of individuals of Walker’s manioc and Zapata bladderpod, but approaches several known locations of Texas ayenia. For this reason, impacts on federally listed plants are anticipated to be short-term, moderate, and adverse." This excerpt is typical of the ESPs in that the risk to endangered plants is deemed short-term without any quantitative population analysis.
By August, 2008, more than 90 percent of the southern border in Arizona and New Mexico had been surveyed. The remaining portions will be surveyed in the next three months. In addition, 80 percent of the California/Mexico border has been surveyed.
