The design as shown does not reflect drau7age or field surface types, as these decisions may need to be considered on a case-by-case basis, Field Drainage Field drainage could be accomplished by either a "crowned" field with a slope of 1-1 '/z %, or a sheet or a modified hip slope. There is disagreement among field designers and field managers about the pros and cons of each approach. We recommend that the site features (the lay of the land), other standards or rules (as in watersheds), and the planned use of the field should be considered on a case-by-case basis as drainage is addressed. Fleld Surface Tit terms of field surface, field development costs can be lowered by using the approach of developing ovei the natural soils present on site, Once the grass has begun to establish itself, the soil can be modified the soil with periodic top dressing which can be performed in house, We feel this is a preferred approach in most cases, although in some situations the application of sod as a field surface may be warranted, Both surface topes have limitations that largely relate to overuse -grass fields, if used too frequently/extensively and in poor weather, can be damaged to the point that fields must be rotated out of commission for a growing season, Sod surfaces can also not withstand heavy usage in poor weather or overuse for extended periods without being lost to damage, Within the County's boundaries, there have been occasions in the past two yeazs where both grass and sod field surfaces have been closed down because of overuse, Field design should allow for movement of the goal mouth areas. Additional ideas and rationale for the prototype design can be found as Attachment 2. The draft prototype field shown here was designed using staff and work group discussions, landscape and athletic field design principles, and the book. worts Fields: A Manual for Desierr Construction and Maintenance by Jim Puhalla, Jeff Krans, and Mike Goatley Although not addressed at this time, other prototype field designs for softbalUbaseball and other fields could be developed as needed or desired.
