4.10 Geometric Layouts

Projects that do not require the formal geometric schematic as defined in
Section 4.3
can use a more simplified geometric layout to convey project information if the District desires. A geometric layout can be developed for a single preferred alignment to gain feedback from project stakeholders.
The geometric layout can be used as the Initial (30%) milestone submission in lieu of plan and profile sheets at the discretion of the District.
The geometric layout typically contains the following design elements:
  • Typical sections of existing and proposed roadways;
  • Roadway horizontal and vertical alignments;
  • Pavement edges, faces of curbs and shoulder lines;
  • Proposed structure locations;
  • Direction of traffic flow;
  • Preliminary ROW requirements; and
  • Property ownership data.
