Even though the community is located in the desert, Sun City West still has large and developed runoff structures to gather and divert rainwater flows to nearby river beds.
It is seldom that residents or visitors see water flowing in these diversion channels. But when there is a large amount of waterfall for a sustained period of time, like occurrences this spring, the water is plentiful and it often has a lot of debris with it.
Moving water is very forceful and easily moves debris with it.
The canals are administered by the Flood Control District of Maricopa County. The District is responsible for floodplain management and regulation in unincorporated Maricopa County and many communities, especially in the West Valley.
There are several miles of these concrete lined channels in or adjacent to Sun City West. The water eventually drains into the Agua Fria River bed.
