 Mir. Eugene Hackett Chairman of the Executive Committee of the Phoenix Citizens Street Paving Asso- citation. Dear Sir: Your committee on investigation of various classes of paving suitable for the city of Phoe- nix, beg to submit the following re- port:
 In order to ascertain the various kinds of paving which have been successfully used in localities where the conditions of use. climate and soil are similar to those existing in Phoe- nix, we have corresponded with the city engineers of the following cities: Fl Paso, Texas; North Yakima Wash; ogden, Utah; Fresno. Cal: Redlands. Cal; Riverside, Cal; Boise City. Idaho, and Salt Lake City, Utah From most of these engineets we have received very full information as to pavements in use. including, in many cases. specifications under which these pavements are laid, with full figures as to cost both of main tenance and construction. The in formation gathered from the fore going sources is shown in the at tached tabulated report
 
 information we have secured from the city of Chicago, Kalamazoo. Mich and Springfield. Mass-s information along similar lines, and wehave also had the advice in our investigations of Mir. Carl Sherwood. representing the good roads bureau of the United States government
 These investigations lead us to bolt f1,,e to our local conditions throughout the business section of our city. where the heavy traffic occurs, is either a concrete asphalt pavement, which consists of a wearing surface asphalt laid on a concrete base, or a bitulithic pavement, in which the base is composed of stone mixed with bitumen
 In the residential section. we be- lieve. that an oil macadam road simi- lar to that now being laid on Central Avenue boulevard would best fit ex- isting conditions.
 After receiving these various re- ports from the city engineers we have. through correspondence with various contractors. received esti- mates as to what a concrete-asphalt and bitulithic pavement can be laid for in the business section of this city. Representatives of the Bitu- lithic company have visited Phoenix and advise us, after investigation of the cost of labor, rock and other ma terial, that a first-class bitulithic pavement such as is now used in the business section of Fl Paso can be laid in Phoenix for approximately S250 per square yard.
 Representatives of Fairchild, Gill more, Wilton company, who have laid the concrete asphalt pavements Of Riverside and other southern Cali fornia cities. have also conferred with this committee and have investigated local conditions, and advise us that a pavement like that laid in Riverside can be laid in Phoenix for approxi- mately $2.25 per square yard. We be- lieve. however that on close cOmpeti- ton these prices can be reduced. and an examination of the cost in other cities on the attached table. together with investigation of the local cost of material, shows the reason for our belief.
 Assuming that a first-class pave ment can be laid for $2.25 a square yard, the cost on various streets in the center of the business district would be as follows: On all streets company has its tracks. under its franchise it agrees to pave at its own expense at the time the city paves,
