Thanks to Rob for detailing the relationship between the club and ranch. The owners of the XC ranch do offer significant value to the club, beyond water access.

I am under the impression that the water supply (for growing grass) is a significant part of the monthly fee the club pays to the ranch, following a discussion with the CSS treasurer and the discussed methods for metering the water flow during the last board meeting. But if after a discussion between CSS and ranch owners, the reduction/elimination of watering the LZ would not generate significant savings for the club, may as well keep the grass and related maintenance cost and labor.
