Crews continue to work to keep Omaha's Eppley Airfield as dry as possible.
Through Tuesday, 48 of the planned 70 dewatering wells going in around airport property have been drilled, said Steve Coufal, executive director of the Omaha Airport
Authority. Of those, 23 are operating, he said Wednesday.
Groundwater levels in the areas around the active dewatering wells have dropped between 2 and 7 feet, Coufal said. The wells' effectiveness, he said, will help stabilize water levels and reduce sinkholes and sand boils caused by rising groundwater pressure.
Coufal said crews also have inspected about 40,000 feet of underground stormwater piping with a camera. As leaks are identified, he said, they are evaluated and repaired as needed.
Monitoring continues around the clock, Coufal said. As of Tuesday, he said, 72 distressed areas have been identified on airport property and evaluated, prioritized and repaired as required by methods approved by the U.S. Army Corps of Engineers.
Coufal also noted that North Lindbergh Drive closed on Tuesday for the construction of dewatering piping over the roadway and levee. As the pipes are installed, he said, each will be covered and paved over with asphalt so that the sections of Lindberg can be reopened for use by general aviation tenants and customers.
Officials anticipate that Lindbergh Drive will have at least six such crossings. General aviation access still is available from South Lindberg Drive, Coufal said.
Missouri River levels appear to have stabilized over the past week, Coufal said. The distance from the river to the top of the levee is 7.1 feet on the airport's south end and 9.1 feet on the north.
