CITY AND REGIONAL PLANNING 319 



enable one to picture in his mind the appearance of 

 the land when occupied by houses. He will know 

 that a desirable view, as seen from one house, will 

 not be cut off by the construction of houses on other 

 lots. Planning in this way will insure for the future 

 residents of the subdivision in question as great ad- 

 vantages as should be derived by all the dwellers of 

 a city from careful city planning. 



(7) Having finally made a plan showing streets 

 and lots, with locations for houses, other plats can 

 be made showing pavements, sidewalks, profiles of 

 streets, cross-sections, methods of surface drainage, 

 and location of planting. In staking out the streets, 

 the designer has naturally in mind the grades to be 

 adopted, and has tested these by means of a hand 

 level to ascertain that a grade within the adopted 

 limits is feasible. If there are existing trees on the 

 land that is being studied, these will be taken into 

 consideration in preparing a planting plan and also 

 in fixing the profiles of roadways. Often, by chang- 

 ing the grade of a roadway slightly from that which 

 would naturally be adopted on entirely vacant land, 

 a good tree standing in the parkway can be f saved, 

 and it is usually possible to change the grade without 

 making the road too steep or the profile unpleasant.
