Keyline® in the AR Sandbox #4: Design for Access | Summary and Q&A

TL;DR

Proper road placement in landscape design is crucial to prevent erosion, dehydration, and unwanted water flow, while also providing access and connectivity within the site.

Key Insights

• 🤽 Proper road placement in landscape design plays a vital role in controlling water flow, preventing erosion, and maintaining water management.
• 🌉 Placing roads on ridges minimizes the risk of unintentional streams and ensures that they remain dry.
• 🤪 Roads going straight down slopes can become sources of erosion and landscape dehydration.
• 💦 Roads on embankments can serve as connectors and facilitate water management through overflow features.
• ⌛ The sponginess and absorbency of soils are crucial in reducing landscape runoff over time.
• 💦 Size ponds based on road runoff, as roads will remain compacted and consistently provide water from runoff.
• 🥅 Creating absorbent and spongy soil is the goal to minimize landscape runoff.

so let's look now at the next design layer to add to our model which are roads pathways and access in general the water layer really sets the bones and main patterns of the design in place and the access layer follows it closely for starters let's look at the places where we've already made connecting lines across the landscape our water diversion ...

Questions & Answers

Q: How do water diversion drains and ponds integrate with road placement in landscape design?

Water diversion drains and ponds are incorporated into road placement in landscape design to control water flow. By constructing them simultaneously, the roads can help direct water to the desired locations, preventing erosion and facilitating drainage.

Q: Why is it safer to place roads on ridges?

Placing roads on ridges is safer because there is no water flowing onto the ridge from other areas, reducing the risk of unintentional streams. This ensures that roads on ridges remain dry, while valleys become wet during rainfall.

Q: What happens when roads are placed straight down a slope?

Roads placed straight down a slope can become conduits for water, leading to rapid water movement and potential erosion. They also contribute to landscape dehydration. Thus, it is important to avoid such road placement.

Q: How can roads on embankments be beneficial in landscape design?

Roads on embankments can serve as beneficial conveyors of water. They can connect different areas of the site, providing access and connectivity. Additionally, during rainfall, overflow features from ponds can flow over the embankments, ensuring proper water management.

Summary & Key Takeaways

• Water diversion drains and embankments of ponds are important features in landscape design, as they help control water flow and can be constructed simultaneously with roads.

• Placing roads on ridges is a stable option, as there is no water flowing onto the ridge from elsewhere, minimizing the risk of unintentional streams.

• Roads going straight down a slope can become conduits for water, leading to erosion and landscape dehydration, while roads on embankments can serve as beneficial conveyors of water.
