Construction equipment has arrived on site, marking the beginning of installing the Archery Weir and Silver Bowl Weir at the Las Vegas Wash. The Archery Weir will be located approximately a half mile upstream of the Duck Creek Confluence Weir and the Silver Bowl Weir will be located just south of the DU Wetlands No. 1 Weir. Once completed, these weirs will represent the 18th and 19th of the expected 22 weirs necessary to effectively stabilize the Las Vegas Wash through the Clark County Wetlands Park.
The two weirs will stabilize 20 vertical feet of headcutting channel erosion. The Silver Bowl Weir will measure 263 feet across the Las Vegas Wash, with the Archery Weir stretching approximately 400 feet wide.
The contract was awarded to Las Vegas Paving at a cost of approximately $12 million, several million dollars below the engineer's estimate. The two weirs were combined in an effort to reduce costs and increase efficiencies and has been an effective strategy over the years. The majority of this work will be funded by sales tax revenues with a portion of the Silver Bowl costs being covered by Southern Nevada Public Land Management Act funding.
Construction is expected to be complete by early 2015.
