ALT A smiley waterdrop character asks, "Have you visited the Flood Insurance Rate Map (FIRM) Viewer?" resilientoahu.org/GetFloodReady.
ALT The City updates the Viewer when FEMA makes revisions to the maps. The current maps became effective on June 10, 2026. An image of the map in the Viewer shows the slider function which allows users to compare the historic flood zones to the updated flood zones as of June 10, 2026.

ALT A diagram of different tree species planted appropriate distances from a house to provide shade. Overlaid text states, that planting trees can cool your home and provide food for your family. Trees can reduce air temperature 3-10 degrees Fahrenheit in urban areas and reduce air conditioning needs by 30%. To maximize cooling benefits, plant trees and shrubs to shade windows and roofs from the afternoon sun and paved areas like driveways and sidewalks. Depending on the variety of tree, aalii can be planted 8 ft from a house, citrus can be planted 6-15 ft from a house, avocado or breadfruit can be planted 15 ft from a house, and mango can be planted 20-30 ft from a house. Make sure you have room for the full-grown tree and its roots. Aalii, citrus, avocado, breadfruit, and mango all grow great in hotter, drier areas. These trees provide shade and food or flowers.
