i03 SystemwidePA 20101007

Description

This feature class represents the Systemwide Planning Area. It is one of the three Central Valley Flood Protection Plan (CVFPP) Planning Areas. It is comprised of the following layers:Below are layers that delineate the boundary.1. Levee Flood Protection Zones (LFPZs) developed by DWR as a first estimate of areas potentially inundated due to State Plan of Flood Control (SPFC) levee failure. There are no frequencies associated with these areas. LeveeFloodProtectionZone_20100301 (DWR)2. Comprehensive Study 500 year floodplain delineation (CS_FP_500YR_Dissolve.shp) (DWR)3. 200 year floodplain developed by DWR for the reaches of the Sacramento River upstream of Woodson Bridge which was the limit of the floodplain development for the Comprehensive Study. DWR_FloodPlain_200YR (DWR)4. American River Economic Reevalulation Report (ARERR) 500 Year Floodplain.5. legal_delta.shp6. A 50ft buffer of streams defining the hydrologic connections between multi-purpose or dedicated flood control reservoirs within the WPA.7. Added the multipurpose/Flood Control Reservoirs (MultipurposeReservoirs_20100902.shp)8. If Hydrologic features (Rivers, Channels, bypasses, etc) have SPFC Project levees on BOTH sides of the features… Include areas between two levees.9. If Hydrologic features (Rivers, Channels, bypasses, etc) have SPFC Project levees on ONE sides of the features… Include areas from centerline of the feature to the levees.10. Middle Creek, Adin, and North Fork Feather River project have been added.11. HEC-FDA Impact Areas (the latest version developed with no holes/overlaps) were added as a way of filling in and smoothing the ragged boundaries of the Comprehensive Study 500yr Floodplain.12. Data holes were filled using an automated process and supplemented by visual inspection and manual additions/subtractions.13. Added USACE (Sacrametonto Office - SPK) provided protection areas that intersected the existing SPA except those outside of the Sacramento and San Joaquin Hyrdologic Regions (as defined by CA DWR CalWater 2.2).
