This is part of the San Xavier Farm Rehabilitation Project. Additional entries related to this project can be found at the following link: https://core.tdar.org/collection/27482

The U.S. Bureau of Reclamation (Reclamation) assisted the Tohono O’odham Nation’s (Nation) San Xavier District’s (District) Farm Cooperative (CoOp) in developing some 1,400 acres of new farm land along both sides of Interstate 19 south of the existing CoOp farm fields. This project was in accordance with the provisions of the 2004 Southern Arizona Water Rights Settlement Act (SAWRSA). The farm extension involved mostly undeveloped allotted desert land that has numerous large prehistoric sites in and around the planned fields. Because the project was federally funded and occurred on Indian allotted lands, it was subject to compliance with Section 106 of the National Historic Preservation Act, as amended, and with various ordinances of the District and Nation. Therefore, prior to any ground-disturbing work associated with the project, a cultural resource assessment had to be performed to document the presence, condition, and eligibility of sites that occurred within the project area.
Permission was previously secured by the CoOp from more than 50 percent of the allottees, as documented with the Bureau of Indian Affairs (BIA). At the request of Reclamation, Archaeological Consulting Services, Ltd. (ACS) was instructed to conduct Class III survey of approximately 1,150 acres of proposed new farm fields along the east side of Interstate 19 south of the San Xavier Mission Road exit, magnetometer sampling and excavation of shovel probes within selected sites, and excavation of backhoe trenches in non-site areas to search for potential buried cultural deposits not evident on the surface.
This document presents the results of the survey.

美国垦务局（U.S. Bureau of Reclamation，简称垦务局）协助托霍诺·奥德姆民族（Tohono O’odham Nation，以下简称“民族”）下属圣哈维尔区（San Xavier District，以下简称“区”）的农场合作社（Farm Cooperative，以下简称“合作社”），在现有合作社农场用地南侧的19号州际公路（Interstate 19）两侧，开发约1400英亩的新农田。本项目严格遵循《2004年南亚利桑那水权解决法案》（Southern Arizona Water Rights Settlement Act, SAWRSA）的相关规定。

本次农田拓展项目所涉区域多为尚未开发的印第安分配沙漠用地，在规划农田范围内及周边分布有大量大型史前遗址。由于本项目由联邦政府资助且实施于印第安分配用地之上，因此需遵守经修订的《国家历史保护法》第106条，以及区与民族颁布的各项条例。因此，在开展任何与本项目相关的地面扰动作业前，必须开展文化资源评估工作，以记录项目区域内遗址的存在情况、保存状态及资质认定情况。

此前，合作社已按照印第安事务局（Bureau of Indian Affairs, BIA）的备案要求，获得了超过50%的分配用地权利人的许可。应垦务局的要求，考古咨询服务有限公司（Archaeological Consulting Services, Ltd., ACS）受命开展以下工作：对圣哈维尔传教区公路出口南侧19号州际公路东侧约1150英亩的拟新建农田区域进行三级考古调查（Class III survey）；对选定遗址开展磁法采样与探铲发掘；在非遗址区域开挖反铲沟，以搜寻地表未显现的潜在埋藏文化遗存。
