Streets are laid out in a north -south and east - <br />west grid pattern. Santa Ana Police Department divides the City into quadrants with the intersection of V Street <br />and Flower Street as the center -point. East and West V Street divides the northern and southern halves of the <br />City, and Flower Street divides the eastern and western halves, creating the Northeast, Southeast, South Coast <br />(southwest) and West End (northwest) districts (see Figure 21 below). <br />Topographically, the City consists of a flat, low-lying plain approximately 135 feet above sea level with little <br />elevation change throughout the City. The Santa Ana River, a 96-mile long waterway and the largest river in <br />Southern California, runs through the City and serves as the major drainage channel. The Santa Ana River is non - <br />navigable and mostly channelized (concrete -lined) and is usually dry or very low flowing, except during rainfall, <br />due to the construction of the Prado and Seven Oaks Dams to the northeast of Orange County. Nevertheless, <br />much of the City lies within the historic floodplain of the River and flooding is still possible during storm events <br />or dam failure. Santiago Creek, a major tributary, runs through the Cities of Tustin, Orange and Santa Ana and <br />provides water resources and drainage to the region. Santiago Creek is also low flowing except during rainfall, <br />but is not channelized and is susceptible to flooding or creek bed erosion during storm events. A number of 100- <br />year and 500-year flood plains are located in the City.' <br />' GP Land Use Element; Ped Bike Master Plan <br />12 <br />
