ARRANGEMENT OF TREES ON STREETS. 33 



AEEANGEMENT OP TEEES ON STEEETS. 



Streets of ordinary width, from 60 to 90 feet, are usually best treated by 

 the planting of a single row of trees down each side of the street on the 

 outer edge of the sidewalk (fig. 11). Occasionally there are difficulties in 

 the way of successfully placing even small trees on the sidewalks of streets 

 narrower than 60 feet, as when the buildings are several stories high and 

 erected on the property line. In such a case an arrangement with a single 

 middle row like that in fig. 10 might be advisable, especially on streets 

 running east and west, where the trees planted on the south side of the 

 street would be very largely cut off from sunlight, while those planted on 

 the north side would be bent towards the street. In some portions of the 

 streets of Southport there is a single row of live oaks down the middle of 

 the street. 



Very wide streets often admit of more elaborate planting than a row of 

 trees down each walk. A satisfactory way to treat a street 100 feet wide 

 is a row on each sidewalk and a row on a narrow planting strip down the 

 middle of the street (figs. 12, 13, 14 and 15). The principal streets of 

 Columbia, S. C, are planted in this manner. The trees in the middle 

 strip can either be standard shade trees of the same kind as the lateral 

 rows or ornamental trees or standard trees alternating with ornamental 

 trees. 



Streets from 120 to 150 feet can have the plantings arranged in several 

 different ways. There can be a double row down each of the sidewalks 

 which can be very broad, the row next to the property line being of 

 a standard shade tree and the row next to the driveway being either of the 

 same species or an ornamental tree. 



Another arrangement for a street of such width is one row down each 

 sidewalk with a parking strip down the middle of the street with a double 

 row of trees and a walk in the parking strip. Such an arrangement on a 

 wide street gives a very handsome effect, as is shown in the frontispiece, 

 a view of Green Street, Augusta, Ga, A yet wider street or one in which 

 there is no need for such wide driveways can have a lateral row on each 

 sidewalk and three or even four rows down a central parking strip, the 

 central rows being standard shade trees of some size and dignity and the 

 lateral rows carefully selected ornamental trees (figs. 16, 17 and 18). 



Drives along streams or water fronts can also, when of some width, be 

 planted in double or triple rows. 



In each case a tree should be selected with due consideration for the 

 width of the street and the distance between the houses and the planting 

 line.
