A Street Tree System for New York City 25 



nections upon which successful tree growth of one form or 

 another may be secured. These streets are suggested for our 

 proposed " street tree system,,'' and are shown upon the ac- 

 companying map.* By concentrating our efforts upon these 

 streets it will be possible, with a reasonable annual expendi- 

 ture, to secure a condition of tree planting in Manhattan 

 which will give to the city the appearance and charm of a 

 tree-shaded city. 



In selecting the streets to be used, careful consideration 

 was given not only to the existing conditions of the streets in 

 question, but also to the future development of them. This 

 latter was largely determined by the proposed scheme of dis- 

 tricting being worked out by the City Planning Commission. 

 The streets of our proposed street tree system are confined 

 almost entirely to those streets which lie in the districts 

 limited to residential or restricted business (retail stores, 

 offices, etc.) and residential purposes. 



Several streets which it would be very desirable to include 

 in our system, and whose present condition would permit of 

 tree growth have not been so included because they lie within 

 the proposed unrestricted districts (factories, warehouses, 

 etc.), where the ultimate development would probably ren- 

 der tree growth either impossible or at least unsuccessful. 

 These few streets are indicated separately upon our map, 

 and if by any chance the proposed districts could be slightly 

 changed so as to exclude these streets from the unrestricted 

 districts they should be added to the system. 



There are of course other streets not included in our sys- 

 tem of inter-park connections, but upon which trees may be 

 grown successfully. These are streets which will lie in the 

 restricted residential districts. They, too, are indicated upon 

 the accompanying map.* The program should be to encour- 

 age tree planting by private owners upon these streets ac- 

 cording to the block unit discussed in Chapter V, and public 

 planting should be carried out upon these streets after the 

 main system has been completed.
