Thank you to Matt Heberger of ebmgh.com for sharing this gem off a hydrozone graphic, which he spotted as he opened up his latest water bill from the East Bay Municipal Utility District. Go to his post “Earth to East Bay MUD: Are you stupid, clueless or what?” to see him explain climate zones to the hydrozone guys, then offer alternate (better) schematics. The coup de grass is when he refers to recent water ordinances that show the East Bay MUD schematic out of compliance.
While East Bay MUD is clearly (and very possibly passively) promoting wasteful landscaping, it could be that its hydrozone web page is merely mis-categorized under “conservation tips.” Nowhere in the text on the web version does it pretend to conservation value. Rather, it’s illustrating the concept of irrigation zones, mainly for turf.
And here’s the weird part: The irrigation zones in the schematic are wrong for any type of landscape, conservative or wasteful. A random generator could have placed the plants better.
Let’s start with the band of “high-water flowers” next to the house. This is exactly where you want heavy irrigation provided that you also want the foundations to rot.
Heberger’s got this covered over on ebmgh.com, but for echo value, allow me to demand: Why would a district that is running a rebate program to rip out lawn illustrate its hydrozones schematic with turf front and back? The front use of grass as a default ground cover around the driveway is the perfect set-up to create storm water run-off. Does East Bay MUD mean to promote that?
The lawn-locking of three token “low-water native plants” in the far corner of the back yard was unnecessary, other than to show how to keep it inconspicuous as the natives die from passive irrigation from the lawn sprinklers.
Finally, there is the “shrub zone” illustrated along the sidewalk, where pruning them will be a chore and failure to prune a controversy.
