The goal of the project was to obtain LiDAR elevation of bayside lands at low tide for sea level rise planning. LiDAR data was collected between 8/22/2025 – 10/06/2026 and a 1-ft hydro-flattened Bare Earth Digital Elevation Model in GeoTIFF format was produced. Metadata for the SF Bay Delta LiDAR can be found here: https://lab.data.ca.gov/dataset/2025-san-francisco-bay-delta-lidar <div style='text-align:Left;'><div><div>Staff from Marin County DPW merged tiles from SF Bay Delta LiDAR project into one mosaic GeoTIFF. In order to simplify the data for use in tidal flooding and El Nino preparation maps and apps, staff then reclassed the result into a new raster of ½ ft elevation categories according to the reclass table below:<table><tbody><tr><td>From</td><td>To</td><td>Output</td></tr><tr><td>-500</td><td>0.999</td><td>0</td></tr><tr><td>0</td><td>5.999</td><td>1</td></tr><tr><td>6</td><td>6.4999</td><td>2</td></tr><tr><td>6.5</td><td>6.999</td><td>3</td></tr><tr><td>7</td><td>7.499</td><td>4</td></tr><tr><td>7.5</td><td>7.999</td><td>5</td></tr><tr><td>8</td><td>8.4999</td><td>6</td></tr><tr><td>8.5</td><td>8.999</td><td>7</td></tr><tr><td>9</td><td>9.4999</td><td>8</td></tr><tr><td>9.5</td><td>10</td><td>9</td></tr><tr><td>10.1</td><td></td><td>0</td></tr></tbody></table></div></div></div> <div style='text-align:Left;'><div><div>The County of Marin make no representation or warranties, express or implied, with respect to the use or reuse of the data provided herewith, regardless of its format or the means of its transmission.
