This document discusses principles for sustainable land development. It covers green goals related to the environment, society, and economy. It also discusses ecosystems and ecosystem services, as well as air, soil, and water quality. Best management practices are presented for erosion prevention, stormwater management, and construction. Both non-structural practices like limiting impervious surfaces and structural practices like infiltration facilities are described. The importance of considering the entire development process from master planning to operations is emphasized.
1. Sustainable Principles for Land Development
Sustainable design isn’t about doing something neat, it’s about doing something right.
2. Today, we will discuss
• Green Goals
• Ecosystems & Ecosystem Services and Products
• Air Quality
• Soil Quality
• Water Quality
• And a smattering of best management practices
