There are several approx 28 year old redwood trees growing on county property within 5 feet of a sound wall that extends the length of that continuous sound wall . Over the last 9 years they have grown significantly and the sound wall is currently and progressively leaning proportionate to that growth. I can actually see the roots of the redwood trees coming through underneath the base of the sound wall. Is it within reason to believe that the Redwoods are causing the fence to lean. The county landscape architect is claiming that it's not possible.
