In Mount Airy, we chose the most suitable area for development and began our plan with the creation of a proposed street network. The Proposed Roads mostly follow the topography and are connected to the existing roads. Bridges have been proposed in some areas to help the connection between secluded areas surrouded by streams.

There are certain roads with shared bike lanes and sidewalks. We created a proposed walking trail system that connects to existing walking trails. The road network within our chosen site is organized by a hierarchy system that includes: the Artierals, Collector, Sub-Collector, and Local. These categories are arranged from the busiest roads to the least busiest roads.
Intersection Points
Our street network within our chosen site consist of different road system types that include: the Grid System, Looping System, Lollipop on a Stick System, and Radial System. # of Intersections

The cul-de-sac at the end of a local road has a round green space circle in the middle, roads with shared pedestrian walkways, and trees lining the roadways. Our T-Intersections that are located in the commercial center are two lanes wide. The shown T-Intersection diagram has parallel and perpendicular parking, and tree buffers protecting pedestrians on the sidewalks. In our plans we incorporated many different types of pervious materials.

Our four way intersection is located on the northern side of our commercial corridor. The bulb outs not only define the parrallel and perpendicular parking along the street but also created a shorter distance for pedestrians to cross. This helps make the intersection a safer and more pedestrian-friendly environment. 50

The character we tried to convey in our site is a rustic environment. Conserving as much existing natural environment as possible was important in the design of the development.
