A. In an effort to preserve open space and water resources, a cluster development may contain only one well permit for each single-family residential lot pursuant to Sections 37-90-105 and 37-92-602, C.R.S., subject to the provisions of Section 16.04.040(2) of this Title.

     B. Except in areas of the State where unappropriated water is available for withdrawal and the vested water rights of others will not be materially injured and except inside designated ground water basins, a water court-approved rural land use plan for augmentation shall be required and shall accompany any county-approved rural land use plan when the water usage in the cluster development would exceed an annual withdrawal rate of one acre-foot for each thirty-five (35) acres within the cluster development. Nothing in this Section shall be construed to preclude the use of treated domestic water provided by any public or private entity.

     C. No later than ten (10) days after approval of a cluster development pursuant to a County's rural land use process, the Board of County Commissioners shall notify the State Engineer of such approval and shall provide the State Engineer a copy of the approved rural land use plan that includes the cluster development.
