i03 IRWM Regions

NOTE: The IRWM polygons overlap each other. This polygon Feature Class includes IRWM planning regions participating in the State of California Department of Water Resources IRWM grant program. The data will be included as a component of the DWR Atlas of GIS data and be utilized as the feature data set for GIS projects requiring location of IRWM planning regions. This dataset is not to be utilized for survey purpose and is not designed to that accuracy level. Size of initial data set is 622 KB. Including additional attributes, the dataset is not expected to exceed 700 KB in size. Updates to this data will be once a year or as needed in conjunction with the IRWM Regional Boundaries dataset updates. Some IRWM Regions may decide not to participate in the grant program and will be in the attribute table with no spatial reference. An attribute called “Status” may be added to the feature class table. The data steward will be in charge of updating the dataset and responsible for any versioning. The associated data are considered DWR enterprise GIS data, which meet all appropriate requirements of the DWR GIS Spatial Data Standards. DWR makes no warranties or guarantees, either expressed or implied, as to the completeness, accuracy or correctness of the data, nor accepts or assumes any liability arising from or for any incorrect, incomplete or misleading subject data. Comments, problems improvements, updates or suggestions should be forwarded to the official GIS Data Steward as available and appropriate. The Region Acceptance Process (RAP) is a component of the Integrated Regional Water Management (IRWM) Program Guidelines and is used to evaluate and accept an IRWM region into the IRWM grant program. The RAP is not a grant funding application; however, acceptance of the composition of an IRWM region (including the IRWM region’s boundary) is required for DWR IRWM grant funding eligibility. This dataset includes:-the boundaries of the most current IRWM Regions (as submitted to DWR by the respective IRWM planning region)-their RAP status (Accepted or Conditional) as conferred by DWR the year each entity participated in the RAP-a descriptive field noting the date of any subsequent IRWM boundary changes submitted and accepted by DWR.
