BRIDLE PATHS 



The following notes on the construction of bridle paths are by J. F. 

 Foster, formerly superintendent South Park Board, Chicago, Illinois. 1 

 "When the path has been located and its width determined the sod should 

 be removed from it and used elsewhere. The surface should then be disked 

 and later scraped with a road grader, scraping two inches of dirt from sides 

 to center of the path, thus giving drainage from the center to the sides. 

 Surface water accumulating along the edges should be drained off by 

 means of drain pipes laid and connected with neighboring sewers. In the 

 event that there is no main sewer near they may be drained into the nearest 

 ditches which drain the surrounding country. Special attention should be 

 given to drainage. Two inches of fine cinders should then be used to surface 

 the bridle path. It requires about 500 square yards per mile, and the drain- 

 age will usually require about 3,300 linear feet of drainage pipe per mile. 

 A well constructed, properly drained bridle path is easily maintained. The 

 only subsequent attention that it will need will be to scatter and roll fresh 

 cinders. It will require about 100 square yards of cinders per mile per 

 season. From time to time as the surface becomes compact it should be 

 harrowed and the paths should be sprinkled enough to keep down the dust. 

 We have also used some oil with favorable results." 



The surface of the bridle paths in the Minneapolis parks is of six 

 inches of clay gravel or road gravel. This surface is kept oiled to compact 

 the surface and lay the dust. The range in width of the paths is from ten 

 to twenty feet. 



CONSTRUCTION OF CURBS AND GUTTERS 2 



I. General Considerations. Success in the construction of walks and 

 roads many times depends upon the proper construction of the curbs and 

 gutters, one or both of which may be required primarily to remove the 

 surface drainage. Curbs become necessary sometimes as a feature of formal 

 design but more often as a means of confining traffic to the roadbed or 

 confining drainage water within the road area.
