A move to block Alexandria’s plan for redeveloping its Potomac River waterfront was rejected Friday by a Circuit Court judge who ruled that he could not order city officials to retroactively accept a petition by residents that would force a new vote and require approval by a supermajority.

Judge James C. Clark, in a letter opinion to attorneys representing the residents, said opponents of the city’s redevelopment plan had “adequate remedy” through appeals to either an appellate court or Alexandria’s Board of Zoning Appeals.

The residents tried in January to force a supermajority of the Alexandria City Council — six of seven members — to pass the hotly contested waterfront plan, believing that council proponents could not muster the votes.

But officials refused to accept the petition before the vote because city offices were technically closed. The plan passed 5 to 2.

The opponents, three Old Town residents who have the support of the Citizens for an Alternative Alexandria Waterfront Plan, have already filed an appeal to the zoning board; that hearing is set for April.

“We’re very, very pleased,” said James Banks, Alexandria’s city attorney. “We thought that was the right result but you never can know for sure.”

Roy Shannon, attorney for the residents, did not return calls for comment on the court decision.
