Mr. Corbett replied that there are different requirements for residential and for non - residential projects and that the requirement for separate meters is only for non - residential projects. Commissioner O'Connor inquired if staff envisions eventually requiring separate meters for residential projects for having grey water or recycling water for irrigation. Mr. Corbett replied that the City has had one large home in town where the owner installed a separate meter for irrigation purposes because irrigation water rates were much less expensive. Mrs. Rondash added that the City's Utilities Division indicated that if a residential project owner wanted to propose separate meters, they would potentially have lower bills and other fees may not be tacked on; however, this would be the property owner's option rather than a CALGreen requirement. Commissioner Blank inquired what future incentives might be provided for residential homes utilizing separate meters for irrigation and landscaping purposes. Mrs. Rondash referred the question to Ms. Stern who handles the City's Climate Action Plan. Ms. Stern stated that this would be a good question for the Climate Action Plan and the Energy and Environment Committee to consider as part of the Plan. Commissioner Blank inquired if there were cities that offer incentives for Tier 1. Ms. Stern replied that she did not know whether other cities had enough experience or were already offering any incentives. Commissioner Blank stated that it struck him that the City would limit green building requirements to commercial buildings greater than 20,000 square feet. He indicated that he realizes a 15,000 - square -foot building is not that large and inquired why it would not start at 10,000 square feet. Mrs. Rondash replied that the City's current ordinance specifies 20,000 square feet. She explained that when the ordinance was approved in 2002, it was understood that this was the break -even point where it would not be cost - prohibitive to incorporate these measures into that construction process. Commissioner Blank inquired if this was something staff could propose as a take -away because a lot of technology changes have occurred between 2002 and today, especially in the field of green building. He indicated that he would not be surprised if there were new measures and new construction techniques. He added that he cannot imagine that given construction costs today, a 15,000- square -foot building would be economically infeasible.
