Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P STYLE="margin:0 0 14 0;"><SPAN><SPAN>The spatial features consist primarily of stream line segments exported from the “Q:\GIS_Data\DPW_GIS_Restricted\Streams_DPW_Master.mdb\Streams_MCDPW” feature class. Other other spatial features were exported from: “</SPAN></SPAN><SPAN><SPAN>P:\Flood-Control\Maintenance\RMA\East Marin RMA\Maps\Shapefiles\ RMA_Sites.shp”,</SPAN></SPAN><SPAN><SPAN>“Q:\GIS_Data\DPW_GIS_Restricted\FCWCD_Facilities_Master.mdb\Levees” feature class, </SPAN></SPAN><SPAN /><SPAN><SPAN>and “P:\Flood-Control\Maintenance\RMA\East Marin RMA\Maps\Shapefiles\Fuel_Reduction.shp” as needed to delineate features not along stream features.</SPAN></SPAN></P><P STYLE="margin:0 0 14 0;"><SPAN>The exported line segments were edited (trimmed, merged, etc.) to match the extent of RMA activities at a site, and split into segments to correspond with the RMA Sites as shown on the maps in the directory “</SPAN><SPAN><SPAN>P:\Flood-Control\Maintenance\RMA\East Marin RMA\Maps\Final_RMA_Maps\” .</SPAN></SPAN></P><P STYLE="margin:0 0 14 0;"><SPAN><SPAN>Most of the attributes inherited from the </SPAN></SPAN><SPAN><SPAN>Streams_MCDPW feature class were deleted, but “ALIAS” (alternate feature names) and “Length” (feature length in feet) were retained.</SPAN></SPAN><SPAN /><SPAN /><SPAN>Attributes were added to identify Flood Control Zone (“FCZ”), stream or other feature name (“NAME”), RMA Site ID (“SiteName”). Other attributes (YES/NO fields) were added to identify what activities occur at the site (“Vegetation Maintenance “Sediment Removal”, “Erosion”, “Pump Station”, “Tide Gate”, “Levee Maintenance”, “Fuels Reduction”, “Cattail Cutting”). Note that the Fuels Reduction activity is not part of the SMP but is a maintenance activity required for fire safety.</SPAN></P><P STYLE="margin:0 0 14 0;"><SPAN><SPAN>The layer “RMA_Sites.shp” was used as as a source of values for the </SPAN></SPAN><SPAN><SPAN>“NAME”, and “SiteName” attributes. The spreadsheets “</SPAN></SPAN><SPAN><SPAN>RMA_DFG_List.xlsx” and “AppA_RMA_ProjectAreas_Sites_201206_Update.xlsx” (in directory P:\Flood-Control\Maintenance\RMA\East Marin RMA\Spreadsheets for Activities\) were used as references to the project sites and as a source of the activities values. The maps and the “AppA_RMA_” spreadsheet listed above were also used to identify </SPAN></SPAN><SPAN><SPAN>“Fuels Reduction” and “Cattail Cutting“ activities separately from “Vegetation Maintenance” listed on the “</SPAN></SPAN><SPAN><SPAN>RMA_DFG_List.xlsx” spreadsheet</SPAN></SPAN><SPAN><SPAN>. </SPAN></SPAN><SPAN>EL 06/2012</SPAN></P><P STYLE="margin:0 0 14 0;"><SPAN>The data were updated in 2019 to indicate which segments have vegetation maintenance performed by Conservation Corps North Bay (CCNB) crews under direction from the Marin County Flood Control and Water Conservation District. The maintenance frequency is indicated in the field "VegFrequency". Frequency of activities other than vegetation maintenance is not indicated. Attributes for SMP Site names and CCNB reaches labeled on the map set produced for the CCNB crews were also added to the dataset. Note that this is a draft data layer, and the specific activities listed and the Maintenance Responsibility assigned for the current spatial extents of the segments may not be accurate and need verification and refinement.
