What an 11-Inch Caliche Layer Changes in a Las Vegas Yard is a Mojave decision guide for Las Vegas property owners. It ties the next step to verified local water, soil, season and plant context while leaving uninspected conditions explicitly unresolved.
Expect the hard layer before trenching
The Las Vegas soil series documents a cemented petrocalcic hardpan beginning around 11 inches and extending more than three feet. Probe the actual route before promising trench depth, drainage or emitter placement.
Read alkaline soil and water together
Documented soil horizons reach about pH 8.6. Plant symptoms, irrigation-water chemistry and the property's soil test must be considered together before an amendment is prescribed.
Choose sprinklers by the current SNWA group
Las Vegas sprinkler days are address-assigned, Sunday sprinkler watering is prohibited year-round, and May through August use cannot occur from 11 a.m. to 7 p.m. Verify the current group before programming.
Build a hydrozone map above the caliche
Group emitters by plant demand, exposure and rooting volume. The map should show where the hard layer was observed so later repairs do not rediscover it by accident.
Las Vegas irrigation evidence for pressure, overspray, and infiltration
For a Las Vegas property, log the SNWA watering group, each hydrozone and the depth reached by a soil probe before resistance. Photograph suspected caliche, reflected-heat walls, cold pockets and turf areas whose function is being evaluated. Identify whether a plant is Sonoran or Mojave native, southwestern native, or simply adapted; those labels are not interchangeable. Also record the property class before discussing Nevada’s nonfunctional-turf law. This Mojave worksheet separates a physical constraint, a program rule and a design preference. For this irrigation page, circle the observation that would change the next decision and name who will verify it.
Bank the caliche depth, SNWA group and hydrozone map with the Mojave plan, because those three facts control different parts of the work. For this irrigation decision, the current authority and photographed property condition control.
Treat timing choices as an evidence decision within property planning. Attach quantities, observations, and selections to the relevant property zone, then separate confirmed work from options that still await approval.
