Culvert questions for Zerolene construction
December 2, 2016
Carson Valley's own road to nowhere will be the topic of serious discussions at three meetings next month.
The Towns of Minden and Gardnerville, along with the Douglas County Planning Commission will decide what happens to Zerolene Road, the proposed access to the middle of the Ranch at Gardnerville.
At issue are the standards for flood control on the road.
County officials say that at least one lane of the access to the property has to be open during a 100-year-flood on Martin Slough, which it crosses.
The county is seeking eight culverts with no dip section, which is an improvement over the previous requirement for a 140-foot clear span bridge.
Engineer Rob Anderson, representing the owners of the project, is proposing six culverts and a dip section that would allow a foot of water to cross the road in the 100-year flood.

The periodicity of a flood refers to the odds that a certain amount of water will arrive in any given year. There is a 1 percent chance in any year that a flood large enough to be considered a 100-year flood will occur. The odds of a second 100-year flood in less than a century are the same each year.
Zerolene would serve 600 homes in the middle of the Ranch at Gardnerville, home to 1,500 people.
Anderson said the county's proposal would raise the base flood elevation by .44 feet, flooding someone's building with 2 inches of water.
"Eight box culverts will violate federal regulations," Anderson said. "Changing the road will affect someone's property."
There is also a question about the timing of Zerolene as the sole access to the project. At some point Muller Lane Parkway will be built, connecting the two roads.
Work on The Ranch came to a halt last year after a bankruptcy resulted in the property going back to the original owner.
Gardnerville Town Board members are expected to hear the item on Tuesday and Minden will get it on Wednesday.
