Hi Will -

Yes, 10 - 12 trees should be adequate with the berm.

Good morning Jeff,
 
The proposed earthen berm along the southeast property line was designed to meet the  City of Portland Tech Manual Section 4. We would agree that the berm in upon itself will provide screening. The ordinance provides the following, “Were fencing or masonry wall is proposed less landscaping density is required”. I believe the earthen berm meets the intent of allowing less landscaping density. 
 
If the trees were set apart 30 ft then the berm would be planted with 16 trees could the amount of trees be reduced to say 12 trees? 
 
As a result of the abutting railroads accepted practice of spraying herbicide to control vegetation the plantings will be placed on the slope or top of the berm. I have personally witness the effects of this spraying while working on the Mountain Division Rail Expansion Windham/Westbrook last year. The herbicide certainly works as intended and doesn’t always respect property lines.
