1.1 This guide covers techniques that are appropriate for the construction and maintenance of skinned areas on baseball and softball fields. This guide provides guidance for the selection of materials, such as soil, sand, gravel, crushed stone, crushed brick, calcined clay, calcined diatomaceous earth, vitrified clay, etc., for use in constructing or reconditioning skinned areas and for the selection of management practices that will maintain a safe and playable skinned surface. Although this guide is specific to baseball/softball, it has application to other sports where ball bounce, ball roll, or player footing, or a combination thereof, are of importance.

1.2 Decisions in selecting construction and maintenance techniques are influenced by existing soil types, climatic factors, level of play, intensity of use, equipment available, budget, and training and ability of management personnel.
