The Desert…For Many, a Desirable Place to Live
However desirable it may be to live in the desert, there are certain considerations one needs to know about when deciding to build in the desert.
Desert Geology/Climate Very Dry - less than 6” rain per yearRunoff from mtns transports debris to desert floor creating alluvial fans
The Creation of Alluvial Fans
Mapped Alluvial Fans Flood Control has extensively studied the hydrological flows of alluvial fans in the regionHas determined with reasonable accuracy: area of affect of 100-yr flows, depth of 100-yr flows
As development occurs on the desert floor, it becomes vulnerable to the processes of alluvial fan creation
This can lead to property damage
What Can Be Done to Minimize Flood Damage? The home can be elevated above the 100-year flood levelOrient structure to present minimum obstruction to flowThe rest of property should remain free of obstructions to allow free flow of water around home
Future Concerns Increased development can interfere with the efficient transport of water and debris by constricting flows to increasingly smaller spaces between homes
Possible Solutions Divert flow around development and reintroduce flow to alluvial flow below developmentBuild large open spaces within a development to allow relatively free transport of water in direction of natural flow
Example - Rams Hill
Open belts of undeveloped land established along major flood flows
If homes and developments can be designed to accommodate the forces of nature rather than resist them, potential damage to both homes and the desert can be minimized
