Antelope Drain
Date completed: May 2012
Cost: $389,000
Channel construction paid by Subdivision Developers.
Antelope Drain begins east of Antelope Drive and ends at Mountian View Road in the Fort Mohave area. The Antelope Drain channel was designed within three separate subdivisions:
Sun Valley in May 1983,Valley Springs Estates in December 2007, and Everglades Estates in August 2009.
October 2007 was the first recorded inspection of the channel by Mohave County Flood Control District. The District found the channel within in the Sun Valley subdivision to be in a poor condition, filled sporadically with vegetation and medium sized mesquite trees. The dikes protecting the homes were in need of repair and the channel base requiring leveling. The District’s first project at Antelope Drain was within the channel in Sun Valley; clearing all vegetation, repairing the training dikes and, in one area, building up the south side and confining the flow the center of the channel so water was no longer a threat to several homes.
The portion of the channel located in Valley Springs Estates was inspected and found to be in good condition. The rip-rap along the channel walls was well constructed by the subdivision developer and only some maintenance of the five- foot drop structure near the southwest corner of the subdivision was needed. This maintenance was completed in early 2011.
Following a storm event that impacted neighboring subdivisions, the portion of the channel within Everglades Estates was constructed by the developer. The Everglades channel included three drop structures which would clean and slow the flow of the floodwaters. The Mohave County Flood Control District, after inspection and evaluation of the channel, accepted that portion of the channel into the maintenance system program but determined that additional mitigation was necessary. Two culverts were constructed to slow and divert water to Everglades Blvd., where an overflow was constructed to direct water into an existing culvert within a neighboring subdivision. This was completed in May 2012.
