RELOCATION OR REMOVAL
Two properties located between existing speed cushion and Mariners Drive did not sign petition. Criteria for location not met. Relocation would be difficult.
• Removal would cause the speeds to revert back toward the original speeds. An increase of 6 — 9 mph.
• Based on history, neighborhood support, location criteria and speed reduction, staff recommends to maintain speed cushion in existing location.
