varying widths along the outer edges of the pavement. These are broken only 

 for driveways and entrance paths. The matter of width is one worthy of 

 considerable attention. As we find them today they vary from eighteen inches up. 

 Obviously it is absurd to plant a tree in an eighteen inch parking, but it is 

 done and people wonder why the pavements are lifted J For the best success of 

 the trees the parking space should be four feet at the vary lowest and a strong 

 preference for ten foot parkings. For some species, particularly palms, peppers, 

 oaks, etc., fifteen feet is none too large. 



The roadways vary largely in width and in many cases are too wide. The 

 width must be determined, of course, by the amount and nature of the traffic 

 along the street. Hence, residential streets need not be so wide as business 

 streets. Extra width in residential districts means money wasted in paving, a 

 greater surface to develop dust and a minimizing of parking space thus bringing the 

 duet closer to the homes and to the pedestrian on the sidewalk. In talking 

 with a street superintendent of a certain town which has vary good streets, most 

 of which are eighty feet in width, the opinion was expressed that thirty-five 

 feet was sufficient space for the road and that the rest should go into the 

 parking and pavement spaces. This would produce a spacing as in Fig. . 

 Other arrangements might be made by varying the width of the parking, the width 

 of the pavement or width of the strip between pavement and property lines or by 

 varying any two or all three. 



The question of a central parking space has two distinct phases. The first 

 is the case of the residential street which is very wide, at least one hundred feet. 

 Then a wide parking space can well be spared from the center of the roadway and if 

 judiciously planted will add much to the beauty of the street. In most cases 

 this central space is used for shubbery planting and for nothing else. Of course 

 in the case of still wider streets with a central carline a planting of trees 

 might well ba used. This has been done in Washington along Pennylvania Avenue, 

 the diagram of which see in Fig. . The other phnse of the central 

 parking is the case of the narrow street flanked by tall buildings where there
