Building 10 A-B, as part of the former Wellton Government Camp, is associated with the Wellton-Mohawk Division of the Gila Project. Construction of the Wel- lton-Mohawk irrigation system began in and was essentially completed in With its completion, Colorado River water was delivered to previously arid lands in the lower Gila River valley. Concomitant to construction of the irri- gation system, the U.S. Department of the Interior, Bureau of Reclamation (Rec- lamation) built Wellton Government Camp to provide office space and housing for employees engaged in fieldwork associated with the irrigation project. Today, the headquarters of the WMIDD stand on the site of the camp offices, and the houses serve as residences for WMIDD employees.

The WMIDD administrative complex is eligible for listing in the National Register of Historic Places as a dis- trict under Criteria a and c (Thompson and Sterner The residential buildings have retained their integrity and contribute to the significance of the headquarters complex.

Description

Building 10 A-B (four-room residence, duplex, Type 4D) is a one-story, wood-frame, rectangular duplex set on a 6"-wide concrete foundation. Concrete piers set inside the foundation and spaced at inter- vals support the floor joists. The building is clad with horizontal wood siding and covered by a shingled, side-gabled roof with exposed rafter ends. The gable ends incorporate louvered vents that move air through the attic space. The north (front) facade is symmetrical, with the two entrances at the center sharing a simple shed roof. The south (rear) facade has two entrances at the center. There are two foundation vents on the east and west facades.

The overall dimensions of the primary building mass are x with a wing on the south (rear) facade that measures x The wing has a low-pitched, shingled roof. Room additions, which each measured x were constructed on the rear facades of Units A and B. The additions have low-pitched, shingled roofs with exposed rafter ends. Vertical wood siding sheaths the additions. Both additions have a concrete-slab foundation. There is an aluminum-frame, hor- izontally sliding window on the south facade of the Unit A addition and two 111 aluminum-frame win- dows on the south facade of Unit B. The concrete-slab foundation for the Unit B addition (southeast facade) extends beyond the east wall to create a concrete pad.

At one time, this area was enclosed with wood siding and a door, possibly for use as a storage room. Originally, the front-porch entry was constructed of wood with simple, square wood posts supporting the porch covering. A stepped, concrete stoop has replaced the wood porch entry, and the support posts have been replaced by thin, metal rods set in the concrete stoop. Similarly, the original wood steps on the south (rear) facade have been replaced with concrete steps. On December 30, the H. P. Adams Construc- tion Company was awarded a contract for remodeling some of the buildings at the camp (Pfaff The current north (front) and south (rear) porch entries and the south facade additions may have been con- structed under this contract.

As originally constructed, the duplex was outfitted with two elevated evaporative-cooling units on the east and west facades. These units were replaced by ground-mounted air-conditioning units connected to the building by exterior ductwork. At the time this building was evaluated, the air-conditioning units and some of the exterior ductwork had been removed. Two heating vents and four plumbing vents extend upward from the roof. Originally, there were 22 616 double-hung windows on the building's facades ..Currently, there are 14 aluminum-frame windows in use on the original building's facades. The original window on the south facade of the Unit B utility room has been filled in.

The original windows on the east and west facades of the utility rooms and the four original Wellton-Mohawk Irrigation System, Building IO A-B (Duplex) HAER No. AZ-68-P (page 3) windows on the south facade of the primary building mass are covered by the room additions. The front entrance to Unit A and the front and rear entrances to Unit B are covered by metal security-screen doors. The exterior doors on the north and south facades are not original. This duplex was converted in from the barracks building sections moved from Yuma Army Air Field to the Wellton Government Camp site. Yuma Army Air Field was activated in as a train- ing base for aviation cadets.

At the end of the war, the base was deactivated, and in Reclamation acquired both real and personal property at the inactive facility for use on its projects. Some of the build- ings were used in the construction of the government camp at Wellton (Reclamation 1949a:22-23). Each half of the Type 4D residence has four rooms: a living room, two bedrooms, and a utility room. In addi- tion, there is a kitchen and bath (Reclamation l ). B ui!ding l 0 A-B has approximately square feet (including the room additions). Documentation for this report did not include visual inspection of the building's interior.

Pfaff previously described the remodeled, temporary, two-bedroom duplex as having wood floors covered with salvaged linoleum, plasterboard interior walls, new linoleum counter- tops, Venetian blinds, and an evaporative-cooling system. The cost to move, set up, and convert Building 10 A-B was (Pfaff Currently, Building 10 A-Bis unoccupied; the condition of the building's exterior is fair to poor. III.
