The proposal to build bicycle trails through Santa Cruz’s Arana Gulch greenbelt could be re-introduced soon to the Coastal Commission, which voted yesterday to reject the plan. Commissioners split 5 to 5, with dissenters arguing that the city’s plan did not do enough to protect the endangered santa cruz tar plant. Commissioner mark stone, of santa cruz, has submitted a proposal to waive the usual 6-month period before the commission re-hears the issue. His proposal is set to be voted on at the commission’s meeting next month.
