Football Field Design TRF 230
Introduction • Football exerts different stresses on turf than other sports • Turf acts simply as a surface to move player along (ball role is not an issue) • Speed and bulk of players (middle third of field often destroyed by end of season) • Season is not during a period when turf is actively growing • Field often used for other actives
Survey and Layout • 360 feet X 160 feet • Layout is along a north-south axis • Crowned Longitudinally down the center of the field • Some fields are built flat and slope in one direction
Design Criteria for New Construction • 1 to 1.75% slope • Subsurface drainage may be required for fields with less slope • Use of field (practice or game field) • Game fields may see 15-20 events • Practice fields need to be larger to accommodate more use
Safety Issues • Barrier between fans and players should be placed 20-25 feet away from the side lines to insure adequate stopping distance • Special attention to barriers needs to be paid at the end zones of the field
Field Designs with Preferred Contours Crowned field with level side lines • Easy to build and works well • Problems can occur where the slope levels out at the sidelines (wet area) • If the field is also used as a soccer field this area often becomes un satisfactory
Field Designs with Preferred Contours Flat sloped field • Often built when existing contours cause it to be too expensive to build a crowned field • Water has to move twice a far to exit the field • Sub surface drainage needs to be installed in the lower portion of the field
Multiple Field Layouts • 60-80 feet separation between fields side by side • 30-40 feet separation between fields end to end • Each field should have it’s own separate drainage
Installed Irrigation Systems Three factors to consider • Placement of sprinkler heads (where is most of the play on the field taking place) • Size of the exposed surface area of the sprinkler head (smaller the better) • Durability of the sprinkler heads (sports field heads with a rubber cover)
Installed Drain Systems and Catch Basins • Pipe Drains • Strip Drains • Catch basins (20 feet away from sidelines) four per field
