After fourteen years of planning, the Lake Merritt Dog Park may be dead for good. Nearly 100 people attended last night’s Planning Commission meeting to weigh in on the proposal, and by 11:10 p.m. the four commissioners finally issued their pained decision: denial. Speakers, who each had a minute at the mic, were split nearly down the middle. For every pro there was a con, and for every argument a rebuttal. But in the end the commissioners decided by a vote of three nays and one abstention that the open lawn near the corner of MacArthur Boulevard and Lakeshore Avenue, at the northeastern corner of Lakeside Park, was wrong for a fenced-in dog run.
