Eelgrass beds are highly dynamic and the exact location and\nextent of eelgrass beds can change across seasons and years. Thus, the purpose\nof the 45-meter growth buffer, as described in the</span>\u00a0National Marine Fisheries Service's LTMS Programmatic Essential\nFish Habitat consultation is to account for areas between eelgrass patches,\ntemporal variation in bed extent, and potential bed expansion. In cases where a\ndredge project intersects with the 45-meter growth buffer direct impacts to\neelgrass may occur and therefore assessment, minimization, and mitigation\nmeasures may be required on a project-by-project basis. \u00a0A pre-dredge eelgrass area and density survey is\nrequired 30 days prior to the start of dredging and should be submitted to the\nLTMS permitting agencies.\u00a0</p><p><span>Methods for creating this layer are as follows: </span></p><p style='margin:1 1 1 20;'><span>Downloaded Baywide Eelgrass\nSurveys for 2003, 2009, and 2014 by Merkel &amp; Associates, Inc.

Loaded all layers into ArcGIS Pro \u00a9 ESRI and re-projected\nall data to NAD 1983 UTM Zone 10N. Used Buffer tool to develop a single\nmultipart shapefile with a 45-meter buffer of the input layers. Imported the\nPacific Marine and Estuarine Fish Habitat Partnership (PMEP) Estuary Extent\nlayer and clipped the 45-meter buffer over terrestrial areas based on the PEMP\nEstuary Extent. Some minor adjustments were made where the buffer layer\nresulted in fragments on land or behind levees.<br /></p></div>", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://gis.data.cnra.ca.gov/datasets/BCDC::sf-bay-eelgrass-45m-buffer-bcdc-2020", "format": "HTML", "title": "ArcGIS Hub Dataset"}, {"@type": "dcat:Distribution", "downloadURL": "https://gis.data.cnra.ca.gov/api/download/v1/items/c1acd83696c44e53a0b88cac28c6ae1e/csv?layers=0", "format": "CSV", "mediaType": "text/csv", "title": "CSV"}, {"@type": "dcat:Distribution", "downloadURL": "https://gis.data.cnra.ca.gov/api/download/v1/items/c1acd83696c44e53a0b88cac28c6ae1e/geojson?layers=0", "format": "GeoJSON", "mediaType": "application/geo+json", "title": "GeoJSON"}, {"@type": "dcat:Distribution", "downloadURL": "https://gis.data.cnra.ca.gov/api/download/v1/items/c1acd83696c44e53a0b88cac28c6ae1e/kml?layers=0", "format": "KML", "mediaType": "application/vnd.google-earth.kml+xml", "title": "KML"}, {"@type": "dcat:Distribution", "downloadURL": "https://gis.data.cnra.ca.gov/api/download/v1/items/c1acd83696c44e53a0b88cac28c6ae1e/shapefile?layers=0", "format": "ZIP", "mediaType": "application/zip", "title": "Shapefile"}, {"@type": "dcat:Distribution", "downloadURL": "https://services2.arcgis.com/4Z9x989NrBVrvFwm/arcgis/rest/services/SF_eelgrass_45m_buffer_BCDC_2020/FeatureServer/0", "format": "ArcGIS GeoServices REST API", "mediaType": "application/octet-stream", "title": "ArcGIS GeoService"}], "identifier": "62576b3c-311b-40f1-985d-9928a6daa7bc", "issued": "2021-01-20T22:23:28.000Z", "keyword": ["BCDC", "CAOpenData", "California Natural Resources Agency", "California SF Bay Conservation and Development Commission", "Dredge", "Eelgrass", "Habitat", "SFBayConservationDevelopmentCommission", "San Francisco", "San Francisco Bay Conservation and Development Commission", "Subtidal"], "license": "http://www.opendefinition.org/licenses/cc-by", "modified": "2021-08-06T00:54:17.270Z", "publisher": {"@type": "org:Organization", "name": "San Francisco Bay Conservation and Development Commission"}, "theme": ["Natural Resources"], "title": "SF Bay Eelgrass 45m Buffer (BCDC 2020)"}
