Got a client who owns a hotel. Has a narrow strip of turf in between breezeway and parking lot. He's asked us to install irrigation, new soil and new turf. I was thinking of using Netafim Drip lines under the turf instead of sprays to keep water off the walk way, and in turn, reduce his liability in case of someone "slipping and falling" on a wet sidewalk. Has anyone here ever done subsurface irrigation under turf with drip line? Any input would be appreciated!
