Many athletic field constructions utilize high proportions of sand as a basis to produce high-performance to moderate-performance athletic fields. In many cases, the performance demands or the available budget do not warrant the construction of sand-based rootzone constructions. In these cases, the in-place native soil or fine textured, native-type imported topsoil is used for field construction or renovation. The scope of this standard is to provide some guidance for use of these types of soils for developing acceptable athletic fields. Soil-based fields typically have limited internal soil drainage (low infiltration, low Ksat). The permeability of the soil may be further reduced as the soil compaction level increases, particularly in high-wear areas. The key to maintaining drainage on these types of constructions is to provide for surface drainage by use of a sloped surface or crown. Very heavy-textured soils ( 45% sand content) will have very limited infiltration capacity and should be crowned from 1.5% to 2%. Moderate-textured soils (45% - 70% sand) should utilize a slope/crown grade between 1% to 1.5%. Sandier soils ( 70% sand) should perform well with slope/crowns from 0.75% to 1%. Crown/slope grades below 0.75% should not be used for systems which are not constructed with high-performance processed sand-base systems.
Many athletic fields exist which are constructed with local topsoil materials. Higher performance sand-based systems may not be warranted or desired for many applications/sites. This standard is intended to provide guidance for maximizing the performance potential for fields constructed with these native-type (heavier textured) soils.
