Measure V opponents argued that any claims it will reduce development are merely on paper, and it would actually boost traffic over what exists today by more than 120,000 trips per day.
It's not clear what will happen if the measure fails, but the city has been told twice by state officials to update the general plan.
The Greenlight residents group, which supports voter control over major developments, last week announced it is endorsing City Council candidates Brenda Martin, one of four candidates for the District 1 seat, and Dolores Otting, who is challenging appointed Councilman Keith Curry in District 7.
The group opted not to endorse Councilman Dick Nichols, who won a seat in 2002 with Greenlight backing. Group spokesman Phil Arst said that as an incumbent, Nichols seemed to be in a stronger position than the other candidates, and the group only has limited resources in this campaign.
A pact between the city and Orange County got two big changes Friday, when officials stripped it of two controversial items affecting Santa Ana Heights. The agreement's central point gives Newport Beach veto power over future expansion at John Wayne Airport, and that is unaffected by the changes.
County officials took out an item to let Newport Beach develop a park on a county-owned parcel at Mesa Drive and Birch Street, and one that would have given Newport sole jurisdiction over whether to complete a horse trail along Mesa Drive.
Supervisor Jim Silva said there was too much opposition from other board members to those items, so they were scrapped. The amended agreement goes to supervisors and the City Council on Tuesday.
