Project Regulatory Approvals

Field renovation projects typically always require grading and drainage approval from the local jurisdiction

Grading with over 500 cubic yards typically triggers an environmental checklist and a grading permit

Project Regulatory Approvals

Drainage approvals may include: Turbidity monitoring plan during construction Drainage discharge rate control Storm water detention storage Water quality treatmentApproval typically requires plans and calculations prepared by a licensed design professional

Typical Synthetic Turf Selection Process

Form a committee with coaches, trainers, maintenance staff, administration, and user groups

Visit other synthetic turf fields, don’t just look at samples!

Research who you will be manufacturing, installing, and warranting your field
