Driver experience Concern with adjacent north end auto dealership/restaurant operation Linda Isle association requested roadway remain unchanged Tentative Schedule Preferred alternative selected by City Council Begin Design: Winter 2016 Review 50% Concept Spring 2016 (refined layout and landscape pallet) Begin Construction: Fall 2017 Alternative Summary No Change Alternative - $1,200,000 Repave roadway with existing layout and Rehabilitate traffic signals Four -Lane Alternative (Concept 1) - $1,800,000 Moderate Traffic calming benefits Bike lane and Pedestrian Facility Improvements Preferred alternative for most HOA's Hybrid Alternative (Concept 2) - $2,200,000 Reduction from 4 to 2 lanes Roundabout at Harbor Island Drive intersection Greater potential traffic calming benefits Increased cycling comfort/reduction of sidewalk riding Preferred alternative for residents that front Bayside HOA concerns with reduced capacity and roundabout NOTE: Estimates are concept level.
