Census Blocks and Flowline Intersections

Creation Process:

• The map was created using GIS data in ArcGIS Pro, integrating Census Block data and flowline data from the National Hydrography Dataset (NHD).

• The Census Blocks were clipped to the boundary of Salt Lake County, and flowlines representing rivers and streams were added to the project.

• Using the Select by Location tool, Census Blocks that intersected with flowlines were identified and displayed. This intersection highlights critical areas for environmental management.

• The basemap was set to Imagery to provide detailed background context, showcasing the natural and built environment.

• Standard map elements such as the title, scale bar, north arrow, and legend were added to enhance readability.

Visual Details:

• Flowlines are depicted in blue, contrasting against the light yellow Census Blocks to clearly show intersecting areas.

• The map includes an inset showing Salt Lake County’s location within Utah and an enlarged detail of a selected area, enhancing spatial context.

• The legend explains the symbology, ensuring the map's information is accessible and easily interpreted by viewers.

• The map highlights how urban areas interact with natural waterways, emphasizing the need for protective environmental strategies.
