Cultural Resources Investigations along Reaches 1 and 2 of the San Carlos Irrigation Project Rehabilitation, Florence, Arizona: Project Area Shapefiles

In accordance with the provisions of the 2004 Arizona Water Settlement Act, the Bureau of Reclamation, Phoenix Area Office (PXAO) assisted the San Carlos Irrigation and Drainage District (SCIDD) in the preparation of an environmental assessment (EA) prior to the rehabilitation of portions of the San Carlos Irrigation Project, a Bureau of Indian Affairs water delivery system that serves both the Gila River Indian Community and SCIDD. The project area extends along the current and realigned portions of the Florence Canal, from the sediment basin just south of the Ashurst-Hayden Diversion Dam to Picacho Reservoir. In order to comply with stipulations set forth in the EA, all historic properties within the expanded APE must be mitigated prior to construction. At the request of PXAO, Archaeological Consulting Services, Ltd. prepared a historic property treatment plan (treatment plan) to conduct Phase 2 data recovery at AZ U:15:676(ASM), eligibility testing at AZ U:15:861(ASM), Phase 1 data recovery for the new and previously uninvestigated portions of the canal alignment at AZ U:15:124(ASM) and AZ U:15:663(ASM), and Phase 2 data recovery based on previous excavations within the revised APE at AZ U:15:663(ASM). These shapefiles are associated with the project area and APE.根据2004年《亚利桑那州水资源解决方案法案》的相关规定，美国垦务局（Bureau of Reclamation）菲尼克斯地区办事处（Phoenix Area Office, PXAO）协助圣卡洛斯灌溉排水区（San Carlos Irrigation and Drainage District, SCIDD），在圣卡洛斯灌溉项目的部分区段修复工作开展前，完成了环境评估（environmental assessment, EA）的编制工作。该项目为美国印第安事务局（Bureau of Indian Affairs）管理的输水系统，服务对象涵盖希拉河印第安社区与SCIDD。项目区域沿弗洛伦斯运河（Florence Canal）现有及重新规划的区段延伸，起点为阿什斯特-海顿分水坝（Ashurst-Hayden Diversion Dam）南侧的沉沙池，终点至皮卡乔水库（Picacho Reservoir）。为符合环境评估中载明的条款要求，扩建后的潜在影响范围（Area of Potential Effects, APE）内的所有历史遗产，均需在施工前完成保护补偿措施。应PXAO的请求，考古咨询服务有限公司（Archaeological Consulting Services, Ltd.）编制了一份历史遗产处理方案（以下简称“处理方案”），具体工作内容包括：对遗址AZ U:15:676(ASM)开展第二阶段数据恢复工作，对遗址AZ U:15:861(ASM)开展遗产资格评估测试，对弗洛伦斯运河新规划区段及此前未勘探的区段（遗址AZ U:15:124(ASM)与AZ U:15:663(ASM)）开展第一阶段数据恢复工作，以及针对修订后APE内AZ U:15:663(ASM)区域的既往发掘遗存开展第二阶段数据恢复。本批形状文件（shapefiles）与该项目区域及APE范围相关联。
