Name: RiverineFinal

Display Field: objectid

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P STYLE="margin:0 0 11 0;"><SPAN>This layer was initially developed by WPRP by conflating several datasets with information regarding frequently flooded roads. In July of 2019 BOH GIS Intern Adam Mills was assigned to update this layer by verifying the data points in the layer as well as adding new data to it in order to create a more complete map of flooded roads. This layer was added to a mxd for this project and then a field labelled STATUS was added to the table in this layer, which used coded data values to indicate if the point was confirmed as flooded or not in the past. In order to verify points already existing in the layer, other shape files were used for verification(EOC Historic Flooded Roads, DPW WPRP Potentially Overtopped Crossings, and Flood Prone Communities). In addition to adding these files to the map document, other shape files were added such as, the street centerline, culverts, bridges, streams, aerial imagery, ADC Grids, altitude, address points, outfalls/inlets, District Yard boundaries, and the county boundaries. These layers helped to contribute to where points should be placed by indicating potential areas that could flood. Adam Mills also utilized data outside of ArcMap to verify points, such as pdfs containing pictures of flood plains and excel sheets(Nuisance_Storm Road_Community Flood Locations 7_2019 and Fld Prone Rds_Must Chk Locations 1_2018). In this process Adam found points that were not in the layer and added them at the appropriate locations, making note of the addition in the comments section. The next step was to go through the 5 year and 10 year emergency service request lists excel sheets in order to see all the areas where flooding has occurred to drop points to represent these areas. Once all the data had been reviewed, Adam Mills created a feature data set and converted the layer containing flooded roads to the same projection as the streets layer so a topology could be created between the two. This allowed for all points not along the street centerline to be corrected. At the request of Alex Baquie, BOH Director, Adam Mills then went through all the points again to organize them into 3 categories, which were represented by a coded data value. These 3 categories were; 02 Historically Flooded Rds(Nuisance flooding excel sheet, flood prone rods xls, historically flooded roads layer, and flood prone communities layer), 03 Emergency Service Request(5 yr and 10 yr xls), and 04 Potentially Flood Prone Roads(Watershed studies by WPRP).</SPAN></P></DIV></DIV></DIV>
