Initial returns show 55.61 percent of Arvada voters defeating 2G, a proposed half-cent sales-and-use tax increase for street improvements, compared to 44.39 percent supporting it.
As of almost 8:30 p.m., 64.8 percent of voters had cast their ballots.
Mayor Marc Williams said he felt the campaign for 2G, which he had supported, had failed to justify the needs to Arvadans.
If passed, the sales tax increase would have begun Jan. 1 and concluded Dec. 31, 2028.
The current sales tax rate in Arvada is 3.46 percent. If the half-cent street improvement tax had passed, the sales tax rate would have risen to 3.96 percent, equal to a nickel on a $10 purchase.
Williams said that since the voters had clearly indicated it, the city would have to look for other ways of funding some of the projects 2G had set out to address.
Initial projects included widening existing lanes and improving sidewalks on Ralston Road between Yukon Street and Garrison Street, adding lanes and sidewalks on West 72 Avenue between Simms Street and Ward Road, adding sidewalks in neighborhoods near the G Line Commuter Rail Stations, and closing sidewalk gaps in Southeast Arvada.
