 Bond Proposition.


 Bond Proposition.
 Nogales, Ariz. Aug. 3rd, 1915. To THE
 HONORABLE BOARD OF SUP
 ERvISORS,
 SANTA CRUZ COUNTY, ArIzoNA. GENTLEMEN:
 Pursuant to your request I have made reconnaissance of the Santa Cruz County roads and have prepared an estimate of the amount necessary to place in good condition the principal roads.
 In order to ascertain which are the most important roads. it is necessary to consider, FIRST: The amount of traffic and it's class. SECOND: The number of residents benefited. THIRD: The importance of districts geo. graphically benefited. with the result. I believe, that two good roads should be built complete, one from the Pima Santa Cruz County line south through the Amado, Tubac. Parade and Ca- labasas districts to the end of the State Highway about five miles north of Nogales; and from the Nogales Townsite northeast erly to Santa Cruz River, Pata gonna, Sonoita, Elgin. to the County line. These two roads are the main thoroughfares through Santa Cruz County, and and are therefore the most inn Portant. Tbese roads have many feeders or branches which lead out to important settlements and districts, and should be worked upon in proportion to their re- spective amount of traffic and population. In many instances these roads need permanent inl- provement in local sections.
 Santa Cruz County is fortunate in having very good natural roads, which can be kept in re- pair very cheaply after the bed is once formed and the prop CT water drains once made. A roadway suitable for our needs and conditions is a sixty foot right of way, twenty-four foot road dway, twelve feet of which is grade, crowned and finished, the remainder for the drains or gut ters. This is usually termed a single road. Nearly fifty per cent of the estimated cost of the roads is for the purpose of keep ing drain water from off the road surface. ......
 It is not necessary that brid- ges or culverts be built over each arroyo crossing. If such was the case, it would take near ly three miles of bridges and culverts for the roads contem- plated.
 However, it is more economi- cal in some instances, where deep arroyos are encountered, to build culverts, rather than to grade down to their bed level. I have in my estimate allowed for the grading to the level, build re- taining wall on the lower side of road, where necessary, to pre- vent future cutting, and paving all the arroyo crossings.
 I also suggest to you, and con sider it more economical, that the county should build the major portion of the roads by day labor, with equipment pur- chased for that purpose. The equipment necessary for ecOno- mical work would consist of a heavy tractor and roller. grades, blows, scraperS, wagons, etc. If purchased, these would be of material use to the county in the future for the maintenance, re- pair, and the construction of roads.
 The following is the sum total of items for the contemplated work on the various roads: Santa Cruz River road $50, 400. % Nogales Patagonia
