than 25 per cent of the area of the lot. A tower on the corner of a park 

 and a 60-foot street can rise directly on the street wall on the park side, but 

 will have to set back 45 feet from the 60-foot street line. If, however, its 

 frontage on a 60-foot street were only a quarter of such street frontage, the 

 tower might approach within 20 feet of the street line. The increasing sizes 

 of yards and courts would be constantly operative and it would be desirable 

 so to place the tower that the yard and court provisions would not interfere 

 with it. (See Fig. 146.) 



Sec. 9, Par. (e). Let us suppose it were proposed to erect a building 

 on an inside lot on a 50-foot street in a two and one-half times district and 

 a large building across the street was 525 feet high, an existing building on 

 one side 225 feet high and one on the other side 150 feet high. The height 

 limit on the street would be 125 feet normally. All three of these sur- 

 rounding buildings are well over that limit; one of them by 400 feet; one 

 by 100 feet and one by 25 feet, or a total of 525 feet. Dividing by three 

 would give an excess average height of 175 feet, therefore, according to 

 this provision, the proposed building might rise to a height of 125 plus 175 

 feet, or 300 feet. If at some future time the 225-foot building on one side 

 were to be torn down and a new building erected on this site, the new 

 building could use the 300 feet of the first new building in computing the 

 excess height to which it might rise. Existing buildings lower than the 

 height limit or vacant lots would be considered in this computation as 

 though they were at the height limit. If within 50 feet on either side and 

 directly across the street there were, for example, five buildings, only two 

 of which were higher than the height limit, the excess height of these two 

 buildings would be divided by five in determining the excess height to which 

 the proposed buildings might go. Buildings directly across either street from 

 corner buildings should be considered, but a building diagonally across the 

 corner could not be considered. The proposed building should not be 

 counted in arriving at the above divisor. (See Figs. 147 and 148.)
