Gulp! Rancho Santa Fe is how thirsty?

Visduh, RSF is in the part of the county that has an evapotranspiration demand of somewhere around 3-4 (acre-) feet per year with an average annual rainfall of about 8-10 inches. But actual irrigation application is in the realm of somewhere in the realm of 6-16 (acre-) feet of water per year. That is, the WASTE component at RSF is in the realm of 3-12 (acre-) feet per year. That is, about one million to four million gallons per acre per year. But let’s not just rag on RSF, the poor, unloved devils—let’s ask everybody who’s crowing about conservation, starting with our politicians, to reveal their consumption ratios. The last time I checked my per-acre-equivalent usage (total, not just landscaping, including hosing off the driveway into the bushes, watering when the plants need it any gd day I need to), it was 1.3 (acre-) feet. That's 1.7 feet less than the total evapotranspiration demand (3 acre-feet) where I live in San Diego (seven miles from the coast, or about as far as RSF). About 5.6 inches more than the average annual rainfall. Most of my share goes to fruit trees and vegetables, but my front yard looks like a jungle, not a desert. I keep my plants stressed, not in luxury. And they want me to cut my “usage” by 20% and lecture me about a little water on the sidewalk (running off into the soil), “restrict” me to certain days of the week, and other irrelevant window-dressing. Before we go off half-cocked on guesswork, why not figger a little? What if we allocated residences based on the size of their lots and the evapotranspiration rate in their locations? The billionaire in RSF with five acres would get an allotment of three acre-feet per acre, or fifteen acre-feet per year, and I would get an allotment of 0.5 acre-feet. Folks in El Cajon would get more, because their evapotranspiration demand is about 5 or 6 feet per year. That’s fair, and is based on providing every square-foot with enough water to keep grass green all year ‘round—the luxury-consumption break-point. For commercial and industrial consumers, they would get increases over their base-line according to an analysis of their actual needs and consumption records. Everybody who consumed less than the luxury break-point for their area would be paid for the amount they conserved, but penalties would be assessed for absentee owners who do not maintain their property, including foreclosure properties that are not maintained, in addition to the usual fines for trash and public safety violations. New developments would not be permitted until the developers could ensure (the burden of proof is on them) that sufficient water would be available in perpetuity that would not worsen (exacerbate) the water-supply equation for established properties (i.e., not require a compounding of conservation beyond the baseline established as the maximum sustainable capacity of the state water supply network).
