Fighting the Ocean with a Big Grandstand 



A great beach esplanade has been erected 

 which will provide much needed protection 



The bleacher seats, which have a minimum concrete thickness of twelve inches, rest on sand 

 overlaid with eighteen inches of solidly packed clay. At the top is a wide promenade 



THE winter storms and equinoctial 

 tides which have caused so much 

 damage to the wide stretch of sandy 

 beach which is San Francisco's pride have 

 received a permanent set-back to their 

 destructiveness. A great esplanade, a kind 

 of glorified grandstand, has been erected 

 which is designed to withstand their 

 attacks. On the ocean side the structure 

 consists of five steps, or bleacher seats, 

 anchored in solid rock. The plane of these 

 bleachers is inclined at about twenty-five 

 degrees to the horizontal. Supporting the 



bleachers transverseh- at twenty-foot in- 

 tervals, exeept at the stairways, where 

 they are on ten-^oot centers, are H-beams 

 twenty- by forty-three inches in section and 

 tw«nty-seven and one half feet long. 



From the boulevard or land side the 

 esplanade has the appearance of a massive 

 concrete wall three and one half feet high. 

 The top of the parapet on the ocean side 

 has been made slightly concave, so that as 

 the waves rush up against the wall the water 

 will be thrown back upon itself and will thus 

 lessen the force of the succeeding waves. 



The entire mass oi concrete is tied together with reinforcing iron in such a way that it is 

 practically a solid fortifying wall twenty-five feet in depth and twenty-seven feet wide
