New Geotextile material, where needed, will be installed per the attached plans, “Geotextile Repair/Replace; Detail C” and according to the manufacturer’s recommendation and to the satisfaction of MFCD. Suggested material is 295 SERIES ARCHTECT’S CHOICE LANDSCAPE FABRIC.
MFCD will arrange for water for this project along with access to said water. Some areas may require transport of water from the source for which Contractor is responsible.
