Historically, runoff was disposed of by directing it to the natural creeks, rivers and irrigation ditches that flow through the city.(Top) Approximately 25 percent of the total Planning Area is located within the 100-year floodplain and another 60 percent is within the 500-year floodplain. (Bottom) 8-6 VISALIA GENERAL PLAN UPDATE Monthly mean outflows from Lake Kaweah, the reservoir created by Terminus Dam, range from 81 cubic feet per second (cfs) in October to 1,747 cfs in June. In general, outflows are highest in the late spring and early summer and lowest in the fall. The lake is maintained for flood control, and water is allowed to drain as quickly as possible after heavy rains. At times, the reservoir’s capacity has not been sufficient to handle flows, resulting in flooding downstream. Outflow from Lake Kaweah drains down into the Kaweah River Delta system and through the many drainages and creeks that meander through the City of Visalia. The City’s municipal storm drainage system consists of drainage channels, 23 detention and retention basins, 33 pump stations and 250 miles of pipe. Historically, runoff was disposed of by directing it to the natural creeks, rivers and irrigation ditches that flow through the city. To mitigate the increased runoff due to urbanization, the City has invested thousands of dollars in the purchase of land and the construction of permanent retention basins. See the Parks, Schools, Public Facilities, and Utilities Element for more information about storm drainage facilities. Table 8-1: Floodplains in Planning Area Flood Zones Flood zone mapping by the Federal Emergency Management Authority (FEMA) indicates that approximately 25 percent of the total Planning Area is located within high risk areas within the 100-year floodplain and another 60 percent is in moderate risk areas within the 500-year floodplain (see Table 8-1). FEMA updated the Flood Insurance Rate Map panels for Visalia in June 2009 to reflect the infrastructure improvements made to capture and convey storm water within the city. As shown in Figure 8-2, some areas of the City, in particular in the Northeast and Northwest, are at risk of flooding from a 100-year storm event. Most of the rest of the City is within the 500-year floodplain.
