Trenches lined with geotextile fabric 6. 90-10 sand/organic topmix approx. 12” depth 7. Sand grown perennial ryegrass sod 8. Fixed goals at south end of field Scheduled start date April 1, 2003 Scheduled finish date July 9, 2003
  4. 4. Staging area set up at east end of existing fields
  5. 5. Stockpiling soil for removal
  6. 6. Irrigation lines trenched 2 ft deep into subgrade so drainlines could be installed above irrigation lines
  7. 7. Main drainline at south end of field
  8. 8. Double walled corrugated pipe
  9. 9. Drain lines trenched to a constant depth
  10. 10. Spreading trench spoils away from trench
  11. 11. Packing down trench spoils after spreading
  12. 12. Connecting 20 ft drain sections prior to installation
  13. 13. Packing bottom of trench prior to drain placement
  14. 14. Unprotected drain 8 yrs after construction
  15. 15. Laying geotextile fabric on trench prior to placing pipes

  34. 34. How did it turn out? 1.Fixed goals = conc. wear at south end 2.Worn areas lost stability 3.Turf recovered well after season started 4.Need to rotate drill locations more
