The Dallas-Fort Worth area is being targeted for the largest collective earmark request in the country, according to a detailed breakdown of overall requests released by the House Appropriations Committee.

Why it matters: House appropriators are trying to balance bipartisan momentum for infrastructure investment with "pork-barrel" spending's checkered political history. The data dump is an effort to provide transparency for what are now termed "community project funding" requests.

• The Appropriations Committee released details on nearly 3,000 requests.
• House members are limited to 10 requests each, according to committee guidelines, but there's no overall dollar limit.
• The Texas ZIP Code leading the U.S. in terms of earmark requests is home to Dallas/Fort Worth International Airport, the country's fourth busiest.
• While it's targeted for the most funding in terms of the sums requested, there's no guarantee each of the three requests made for it — filed by three different lawmakers — will be fulfilled.
