At the Apr 23, 2019 BOS meeting (item 9A here) the Supes took up the issue of regulating the development of commercial solar farms in the County - unfortunately after the County has already approved its first solar farm on agricultural land in American Canyon. The staff letter is here.
The Supervisors did not rule out, in this initial discussion, the use of ag lands for solar development. Sup. Wagenknecht even went as far to say that there is only a limited amount of urban and industrial land in Napa County and that he would not want to limit solar farming to those areas which might reduce the amount of development that could occur there. It was ominous that Napa's greenest Supervisor would rather have solar competing with agriculture rather than industry for land. In a foreshadowing of the pitfalls of allowing solar development on ag lands, a solar power proponent spoke in public comments about using lands too steep for winery or vineyard development for solar power.
The idea of using industrial rooftops and parking lots for large scale solar installations was brought up by Sup. Ramos. It is the most sensible solution, particularly since the county seems committed, unfortunately, to millions of square feet of industrial development that involve both huge flat roofs and huge parking lots. State code now requires all non-residential buildings to be "solar ready", but why not go all the way. The solar energy developers should be working with the major warehouse developers to develop a synergy that is profitable for both. The county could produce such a desirable partnership by simply requiring that industrial facilities provide renewable power equivalent to their power usage as part of the conditions of approval.
A 400,500 sf warehouse, Nova Wine Warehouse, will be up before the Planning Commission on May 1, 2019. Hopefully there will be some carryover from the BOS discussion on solar farms to the commission review.
The solar farm discussion followed a previous agenda item (item 9M here) devoted to climate change. Sup. Wagenknecht proposed a proclamation on the need for a regional approach to climate change and the establishment of a county authority to address the issues. According to Dir Morrison, the county's Climate Action Plan is coming back for another public round in a few weeks.
