Experts expect more intense cycles of drought and flooding to be a common occurrence in the future. It is imperative that we capture and bank storm water during wet years, so it is available during periods of drought.
California has dramatically more storage capacity in underground aquifers than is available in surface level facilities. Further, natural groundwater recharge and storage is comparatively inexpensive, amounting to about one-sixth the cost of other options.
Sadly the natural recharge of groundwater has, over the past century, been disrupted by local land use decisions. We have built on and paved our natural landscapes, drained agricultural lands, filled in wetlands, and channelized our rivers, resulting in the loss of untold acre feet of water which otherwise would have been stored underground
This happened without local jurisdictions – nor State and federal government – being aware of the water shortage problem that would eventually develop. While the State of California requires cities and counties to adopt general plans that define where and how they will grow, nowhere in general plan law is there reference to identifying and preserving land well suited to natural groundwater recharge… (more)
