When the power blinks, your site is read on a phone at four percent
The visit you should design for is one hand, cellular data and a homeowner who is already annoyed.
Rain events and Entergy outages produce a very specific kind of traffic. No desktop, no patience, sometimes no home internet, and a battery the reader is rationing.
Design the first screen for that person. What you do, which parishes you cover, and a phone number that dials on tap. Not a full width video, not a slideshow, not a cookie banner covering the only button.
Put the coverage answer in words, not on a map graphic. Orleans, Jefferson and St. Tammany, with the neighborhoods listed underneath. A map image is heavier, slower and harder to read on a small screen than a plain sentence.
Give the emergency path its own route. A person with active water coming in should reach a call button in one tap, without passing through a services menu that assumes they are shopping.
