 traffic. 



In any study of street arrangement for roads, 

 planting and sidewalks, the aim should be to preserve 

 the best effect of space. If possible, the road should 

 be given the appearance of having breadth and free-

 edge of the pavement should be at least twenty feet. 

 Sometimes this may cause the sidewalk to meet the 

 pavement on a curved slanting line, but there is no 

 objection to this if the crossing is on a level with the 

 sidewalk as it should be with the surface water re- 

 moved by catch basins placed along the block in- 

 stead of at the street intersection. 



When a city is on a hill with views out into the

 city plan should always allow the greatest possible 

 freedom for views outside of the city itself. There 

 will, however, be many advantages in having angular 

 and curved streets within the city boundaries as these 

 will display the architecture or planting to better

 fit the topography, reduce cost of construction, 

 and shorten distances. With such planning, there
