<div style='text-align:Left;'><div><div><p><span>The topo bathymetric bare earth digital elevation model (DEM) represents the earth's surface with all water, vegetation and anthropogenic features removed. It was derived from Green and NIR Lidar data using TIN processing of the ground and bathymetric bottom point returns. This version of the topo bathymetric model has not been clipped. Areas of bathymetric voids were triangulated from the nearest bathymetric returns. Users should be aware that bathymetric voids can indicate deeper areas beyond the penetration capabilities of the laser and view these as low confidence areas. A bathymetric coverage polygon has been provided as a separate deliverable indicating where there was a lack of bathymetric returns. The horizontal datum for this dataset is NAD83 (2011), the vertical datum is NAVD88, Geoid 18, and the data is projected in California State Plane, Zone 2. Units are in US Survey Feet. NV5 Geospatial collected the Sonoma Creek Topo bathymetric Lidar data for Sonoma Water between 02/04/2021 and 02/06/2021.</span></p></div></div></div> |

<div style='text-align:Left;'><div><div><p><span>In some areas of heavy vegetation or forest cover, there may be relatively few ground points in the lidar data. TINing the points produces large triangles and hence the elevations may be less accurate within such areas. </span></p><p><span style='font-weight:bold;'>SUBJECT: PUBLIC INFORMATION REQUEST –LiDAR Data</span></p><p><span>The attached information was retrieved from Sonoma County Water Agency CAD-Drafting/GIS Records in connection with a Request for Public Information.
