A Street Tree System for New York City 33 



hence have room for the proper development of fair sized 

 trees. Considerable variety may be secured with this single 

 type by using different species of trees upon the different 

 streets. Probably 95 per cent, of the street tree planting in 

 this country is of this type and nearly all Manhattan streets 

 in which street tree planting is possible may be treated in 

 this way if desired. However, on many of the streets of our 

 proposed system other forms of planting will be more ap- 

 propriate. Typical streets for which this type of planting 

 is suggested are: 



West 86th street (largely existing). 



Lenox avenue. 



Central Park West. 



Fifth avenue (59th to 110th street). 



II. The Third Roiv Type. 



A similar type of planting is that in which in addition 

 to the single or double row of trees on either sidewalk a third 

 row is added in the center of the street. This third row is 

 normally grown in a wide grass or gravel parking or in a 

 narrow parking area preferably fenced. This type of plant- 

 ing is adapted for use on wide streets which do not contain 

 central car tracks. A typical Manhattan street adapted for 

 this form is Seventh avenue, north of Central Park, where 

 the central planting has already been made. In planting of 

 this type the third or middle row may consist of a single 

 or double line of trees depending upon the width of the 

 center parking. (See type V.) 



III. The Center Parking Type. 



Another type of planting which differs but slightly from 

 the above is that in which the central parking is planted to 

 flowers or shrubs instead of trees. This form has been much 

 used in suburban real estate development in many cities and 

 when the street is sufficiently wide and the work is well done 

 produces probably the most attractive form of residential 

 street obtainable. The lateral rows of trees may either be 

 allowed to attain a large size, or, if the proper varieties are 

 used they may be kept to a low formal shape by pruning.
