The heavy fills along the river bottom are forced by the condition that requires sewage to be delivered by gravity at an elevation of eighteen hundred. The large mains of the sanitary sewer system are designed for a population of a hundred thousand and will have to be increased as the City grows larger. The laterals are uniformly twelve inches in size. The water supply is designed with a view of taking care of a future population of two hundred and fifty thousand, and probably will not have to be increased for many years. The storm water system as shown is merely a skeleton upon which a far more extensive system is to be based.
Storm water is discharged directly into the river.
The transportation problem is met by a system of tramways that reach every portion of the City. Finally the park system is extensive and aesthetic and is so interwoven with public buildings and public grounds that nearly twenty-five per cent of the total area of the City is really park.
