"We had great cooperation with the neighbors during the process," he said. "They've been very patient during the process. This will be great when it's all said and done."
Deputy city CEO and Economic and Development Director Peter Naghavi, who was involved in the city's transportation department for various Broadway projects and other issues, echoed Sethuraman.
"In a few weeks, once people get used to it, they will appreciate what we're doing," he said.
"If it's successful, we will do it on other streets that experience similar problems," Naghavi added.
He also predicted a slight shift in traffic to nearby streets from users bypassing the renovated Broadway.
Sethuraman said the city is hoping to complete the project — which is funded by a state Safe Routes to School grant and Measure M money — by the end of the year.
Trees and other vegetation should be coming starting Monday, he said.
'Do you care about speed?'
For 11 years, Michael Moon has lived on Broadway, where he saw cars zoom by as fast 80 mph in what's officially a 25 mph zone.
"I'm sure car owners would rather go faster, but if you live in the place, you'd rather them go 25," he said. "It's hard to maintain a residential feel with the streets becoming traffic-filled."
Jim Fitzpatrick, a Costa Mesa Sanitary District director who lives on Broadway, said while he usually sees staunch opposition to changes in his neighborhood, he hoped any detractors will take pause this time around.
"Do you care about speed?" he said. "If so, please allow this to continue until it is planted and paved, and then we'll take a period to wait and see."
