      If such existing plant material is labeled "to be saved" on site plans, protective techniques, such as (but not limited to) fencing placed at the drip-line around the perimeter of the plant material, shall be installed. No vehicle or other construction equipment shall be parked or stored within the drip-line of any plant material intended to be saved.
      In the event that healthy trees labeled "to be saved" on the approved site plan are destroyed or damaged, as determined by the City Forester, the owner, developer, or contractor shall replace said trees with trees of comparable type.
