1. Brownfields 101 Environmental Engineering Considerations Presented By: Ileen Gladstone, P.E., LSP, LEED

2. Stages of Brownfield Development Due Diligence Acquisition Design Construction

3. Due Diligence Goal: How does Contamination affect the Deal and Development. ASTM Phase I: Identify Areas of Environmental Concern ASTM Phase II: Subsurface Investigation Regulatory Status

4. Phase I Due Diligence Paper Search Historic Information Interview Site Visit Areas of Environmental Concern –Historic use, USTs, metal finishing, dry cleaners,

5. Phase II Subsurface Investigation –Soil borings/test pits/monitoring wells –Soil and groundwater testing Type of Contamination Extent of Contamination How does Contamination effect Development?

6. Acquisition Costs Associated with Cleanup Effect on Property Value Use and Deed Restrictions? Trade-off between cleanup and restrictions?

7. Design Regulatory Framework –Approvals and timetables Programming Choices/Project Layout Data Collection –Geotechnical and environmental Engineering Considerations –Types of foundation –Vapor barriers

8. Design Allocate the risk –Between owner and contractor Contract documents –Health and safety –Soil management –Measurement and payment Premium Costs vs. Base Costs

9. Construction When is the Site cleaned up? –Prior to building construction –Integrated with construction Coordinate with underground construction –Foundations –Parking structures –Utilities

10. Construction Soil Management Dewatering Effluent and Permitting Site Logistics
