Sustainable Principles for Land Development

Sustainable Principles for Land Development Sustainable design isn’t about doing something neat, it’s about doing something right.

Today, we will discuss • Green Goals • Ecosystems & Ecosystem Services and Products • Air Quality • Soil Quality • Water Quality • And a smattering of best management practices

Green Goals Environmental Water Water Quantity Quality Greenhouse Air Gas Quality Energy Emissions Natural Biodiversity Resources

Green Goals Social Equity Community Health Cultural

Green Goals Economic Cost Savings Cost Neutral Cost Additive

Best Management Practices (aka BMPs) Two Types N

Best Management Practices (aka BMPs) Over 200 BMPs for Land Development • Social Goals • Erosion Prevention-Source • Stormwater Quantity & Control Quality/Non-Infiltration • Non-Stormwater Requirements • Stormwater Quality/Non- for the 1200C Permit Infiltration • Erosion Prevention & Sediment • Stormwater Quantity & Control - Runoff Control Quality/Infiltration • Erosion Prevention • Conveying Stormwater • Sediment Control • Restoration • Materials • Transportation • Siting Considerations • Landscapes • Construction Management • Water Use • Operations & Maintenance • Source Control • Urban Food
