"Assisting staff with watering needs of established plants..."

Maybe they should consider plants that can survive on the limited rainfall thereabouts, instead of introducing non-native species that have "watering needs."
Or has the chronic water shortage in SV recently abated?

No the drought has not abated. What they are watering are those plants that are there that were introduced until they can replace them with desert plants.
