Advice from Bay Area landscape experts: highway noise reduction
What plantings would you put to lessen highway noise? We have a long boundary with 280 behind us. Some people have suggested redwoods - mass plantings of 30 gallon ones, to be thinned out in ~ 10 years. Is that the right choice? Are there others?
How big will the redwoods grow? What would be an average life-expectancy? Would their roots cause problems with the foundations of the house?
Any suggestions for sound reduction would be much appreciated.
