FIELD OF THE YEAR Field STMA 1999 II Field of Year in the College SI n egion Field was a star in the City of Birmingham, Alabama, when it was built in 1927 in honor of the American Legion, as a memorial to V.S. Armed Forces mem- bers who gave their lives in service. Legion Field also starred in the 1996 Summer Olympics when it served as ione of four soccer venues. And it's a tar now, as the STMA 1999 Football ield of the Year in the CollegelUniversity division. Legion Field is a city-owned facility that has been expanded and renovated several times over the years to its cur- rent seating capacity of 80,673. Three city departments playa role in its man- agement.

Department of Horticulture and Vrban Forestry, one of James E. Horton, Jr.'s duties is management of Legion Field's turf and landscape. Because "good enough" is not in his vocabulary, perfection is always the goal. His annual management plan includes three improvements to make the program better. These improve- ments were never more evident than in the 1999 field renovation. The original Legion Field hosted hundreds of football games on its native soil and natural turfgrass. As field use increased, artificial turf was installed in 1970 and remained on the field until 1995. Then a major reno- vation was undertaken for the Olympic games. Horton says, "The football field was , expanded to 2.7 acres to accommodate Horton Jr., deputy director of the department of horticulture and urban foresty. soccer.

A Power Drain system was installed, as was a Big Gun irrigation system. This was topped with a 12-inch base of USGA approved sand covered with a 4-inch layer of 80 percent sand and 20 percent Canadian sphagnum peat. To achieve this surface layer, pure peat was spread over the sand layer and tilled into a 4-inch depth. The turf was Tifway 419 bermudagrass.

This brought some of the existing sand into the new material, giving us a 90:10 blend with the per- centage of peat gradually diminish- ing until it becomes pure sand at the base of the profile. So, while we do have some variation within the pro- file, top to bottom, it's a gradual change rather than a distinct layer. This method was determined to be our best solution without total removal and replacement of the entire existing sand profile." Bids for the project were solicited with an opening date ofApril 21, 1999. The target completion date was June 1,1999, with the first game scheduled for September 5,1999. Southern Turf Nurseries was awarded the bid. "Once the project began, it pro- ceeded without problems," says final laser grading, the field was irrigation nozzles similar to water Horton.
