Purpose and Need for the Project Chapter 1.0 – Purpose and Need for the Project
CHAPTER 1.0 PURPOSE AND NEED FOR THE PROJECT CHAPTER 1.0 – PURPOSE AND NEED FOR THE PROJECT 1.1 INTRODUCTION The General Services Administration (GSA) proposes the reconfiguration and expansion of the existing San Ysidro Land Port of Entry (LPOE). The San Ysidro LPOE is located along Interstate 5 (I-5) at the United States (U.S.)-Mexico border in the San Ysidro community of San Diego, California. The proposed San Ysidro LPOE improvements are herein referred to as the “Project.” The total area of the Project Study Area, which comprises the anticipated maximum extent of disturbance, including improvements, staging areas, and temporary impacts resulting from Project construction, encompasses approximately 50 acres. Figure 1-1 illustrates the regional location of the Project, and Figure 1-2 shows the Project Study Area and the Project vicinity. The Project is included in the San Diego Association of Governments’ (SANDAG) 2030 Regional Transportation Plan (RTP; SANDAG 2007); and the 2008 Regional Transportation Improvement Plan (RTIP; SANDAG 2008), which covers Fiscal Years (FY) 2009 through 2013. 1.2 PURPOSE AND NEED 1.2.1 Purpose of the Project The purpose of the Project is to improve operational efficiency, security, and safety for cross-border travelers and federal agencies at the San Ysidro LPOE. Project goals include: Increase vehicle and pedestrian inspection processing capacities at the San Ysidro LPOE; Reduce northbound vehicle and pedestrian queues and wait times to cross the border; Improve the safety of the San Ysidro LPOE for vehicles and pedestrians crossing the border, and for employees at the LPOE; Modernize facilities to accommodate current and future demands and implementation of border security initiatives, such as the Western Hemisphere Travel Initiative (WHTI), the United States Visitor and Immigrant Status Indicator Technology program (US-VISIT), and the Secure Border Initiative (SBI). -

Description of Source Water System
CHAPTER 2 DESCRIPTION OF THE SOURCE WATER SYSTEM 2.0 Description of the Source Water System During the last 100 years, the CSD’s water system has evolved into a very complex system. It is now estimated to serve a population of 1.4 million people spread out over 370 square miles (Table 2.1). The CSD treats imported raw water and local runoff water at three City WTPs which have a combined capacity of 378 MGD. The CSD treats water by conventional technologies using coagulation, flocculation, sedimentation, filtration and disinfection. Recently, all CSD water treatment plants have been modified to provide for the addition of fluoride to the potable water supply. To ensure safe and palatable water quality, the CSD collects water samples at its reservoirs, WTPs, and throughout the treated water storage and distribution system. The CSD’s use of local and imported water to meet water demand is affected by availability, cost, and water resource management policies. Imported water availability decreases the need to carry over local water for dry years in City reservoirs. CSD policy is to use local water first to reduce imported water purchases; this policy runs the risk of increased dependence on imported water during local droughts. Table 2.1 - City of San Diego General Statistics Population (2010) 1,301,621 Population (Estimated 2014) 1,381,069 Population percent change 6.1 Land Area Square Miles 370 Population Density per Square Mile 3733 Water Distribution Area Square Miles 403 Number of Service Connections (2015) 279,102 2.1 Water Sources (Figure 2.1) Most of California's water development has been dictated by the multi-year wet/dry weather cycles. -
4 Tribal Nations of San Diego County This Chapter Presents an Overall Summary of the Tribal Nations of San Diego County and the Water Resources on Their Reservations
4 Tribal Nations of San Diego County This chapter presents an overall summary of the Tribal Nations of San Diego County and the water resources on their reservations. A brief description of each Tribe, along with a summary of available information on each Tribe’s water resources, is provided. The water management issues provided by the Tribe’s representatives at the San Diego IRWM outreach meetings are also presented. 4.1 Reservations San Diego County features the largest number of Tribes and Reservations of any county in the United States. There are 18 federally-recognized Tribal Nation Reservations and 17 Tribal Governments, because the Barona and Viejas Bands share joint-trust and administrative responsibility for the Capitan Grande Reservation. All of the Tribes within the San Diego IRWM Region are also recognized as California Native American Tribes. These Reservation lands, which are governed by Tribal Nations, total approximately 127,000 acres or 198 square miles. The locations of the Tribal Reservations are presented in Figure 4-1 and summarized in Table 4-1. Two additional Tribal Governments do not have federally recognized lands: 1) the San Luis Rey Band of Luiseño Indians (though the Band remains active in the San Diego region) and 2) the Mount Laguna Band of Luiseño Indians. Note that there may appear to be inconsistencies related to population sizes of tribes in Table 4-1. This is because not all Tribes may choose to participate in population surveys, or may identify with multiple heritages. 4.2 Cultural Groups Native Americans within the San Diego IRWM Region generally comprise four distinct cultural groups (Kumeyaay/Diegueno, Luiseño, Cahuilla, and Cupeño), which are from two distinct language families (Uto-Aztecan and Yuman-Cochimi). -
4.1 Aesthetics and Visual Resources
4.1 Aesthetics and Visual Resources 4.1 AESTHETICS AND VISUAL RESOURCES This section evaluates the potential impacts to visual resources and aesthetics associated with implementation of the 2050 RTP/SCS. The information presented was compiled from multiple sources, including information from the San Diego County Draft General Plan and its associated Draft EIR (2010), and the SANDAG 2030 RTP EIR (2007). 4.1.1 EXISTING CONDITIONS Regional Character The San Diego region is an area of abundant and varied scenic resources. The topography of the region contributes greatly to the overall character and quality of the existing visual setting. In general terms, the region is characterized by four topographical regions: coastal plain, foothills, mountains, and desert. The visual character of each is described briefly below. The coastal plain ranges in elevation from sea level to approximately 600 feet above mean sea level (AMSL) and varies from rolling terraces to steep cliffs along the coastline. The coastal plain provides expansive views in all directions, with the coastline visible from some local roadways. Much of the coastal plain is already developed with varying densities of urban and suburban development. Agricultural uses within the coastal area include row crops, field flowers, and greenhouses. The foothills of the San Diego region range in elevation from 600 to 2,000 feet AMSL and are characterized by rolling to hilly uplands that contain frequent narrow, winding valleys. This area is traversed by several rivers as well as a number of intermittent drainages. The foothills are also developed with various urban and rural land uses. Agriculture consists of citrus and avocado orchards as well as row crops. -

Kumeyaay History Viejas Band of Kumeyaay Indians
Kumeyaay History Viejas Band of Kumeyaay Indians The Viejas Band of Kumeyaay Indians, one of the remaining 12 bands of the Kumeyaay Indian Nation, resides on a 1,600-acre reservation in the Viejas Valley, east of the community of Alpine in San Diego County, California. The Viejas Band is recognized as a sovereign government by the United States, with which it maintains a government-to-government relationship. Click here to view the Viejas History Booklet Kumeyaay Indian Nation The Kumeyaay, referred to as Diegueño by the Spanish, were the original native inhabitants of San Diego County. The Kumeyaay, Yuman-speaking people of Hokan stock, have lived in this region for more than 10,000 years. Historically, the Kumeyaay were horticulturists and hunters and gatherers. They were the only Yuman group in the area and were the people who greeted the Spanish when they first sailed into San Diego Harbor with the Juan Rodriguez Cabrillo expedition of 1542. 15, 2014 The boundaries of the Kumeyaay lands changed with the arrival of the Europeans,on September but once extended from the Pacific Ocean, south to Ensenada in Bajaarchived Norte, Mexico, east 12-17489 to the sand dunes of the Colorado River in ImperialNo. Valley and north to Warner Springs Valley. North to northeast, theirof California, territory was bounded by other Indian nations - the San Luiseño, Cupeñov. University and Cahuilla. in White Today, Kumeyaaycited tribal members are divided into 12 separate bands - Barona, Campo, Ewiiaapaayp, Inaja-Cosmit, Jamul, LaPosta, Manzanita, Mesa Grande, San Pasqual, Santa Ysabel, Sycuan and Viejas. One of the largest owners of land in San Diego County, Kumeyaay governments have jurisdiction over approximately 70,000 acres concentrated in East County from El Cajon, Lakeside, Poway and Ramona, to the desert.
