2. Course Information TOPIC: Low Impact Development and Sustainable Site Design Meeting Time Contact Info Goals and Objectives of Course Christopher Obropta, Ph.D., P.E. www.water.rutgers.edu obropta@envsci.rutgers.edu

3. Bioenvironmental Engineering • Concerned with maintaining the quality of our environment • Apply physical, biological, and chemical sciences to design solutions for environmental issues

4. Stormwater Management Stormwater Runoff Result of Development • Impervious Surface Additions • Soil Compaction • Removal of Trees and Vegetation Infiltration, Interception, and Evapotranspiration Reduced Overland Flow Increased

5. Stormwater Management Stormwater identified as a leading source of pollution for all waterbody types in the U.S.

6. Stormwater Management • Three Basic Levels of Management • Regional/Watershed Scale • Community or Neighborhood Scale • Site/Block Scale

7. Conventional Development Centralized Pipe and Pond Control Source: Bill Young

9. Low-Impact Development LID is an approach to land development (or re-development) that works with nature to manage stormwater as close to its source as possible. LID employs principles such as preserving and recreating natural landscape features; and minimizing effective imperviousness to create functional and appealing site drainage that treats stormwater as a resource rather than a waste product. -USEPA

12. LID Approaches • Conservation Design • Cluster Development • Open Space Preservation Source: Pennsylvania State Department of Environmental Protection

13. LID Approaches • Infiltration Practices • Permeable Pavement • Disconnected Downspouts • Rain Gardens, Bioretention Basins, Other Vegetated Treatment Systems Source: USDA NRCS Rutgers Water Resources Rain Garden Walnut Avenue School, Union County NJ Collects and treats runoff from adjacent parking lot

14. LID Approaches • Runoff Storage Practices • Rain Barrels and Cisterns • Green Roofs Rain Cistern ACROS Fukuoka Building in Fukuoka, Japan Rain Barrel

15. LID Approaches • Alternative Landscaping • Native, drought-tolerant plants • Reforestation • Soil Amendments Cardinal Flower Turks-cap Lily Blue Flag Iris Switchgrass Source: New Jersey Native Plant Society

17. Benefits • Environmental • Pollution abatement • Protection of downstream waterbodies • Groundwater recharge • Reduced treatment costs and improved water quality • Ancillary • Reduced flooding and property damage • Aesthetic value • Public space/Quality of life

18. Sustainable Site Design Encompasses green measures used in site design for issues beyond stormwater management

19. Sustainable Site Design • Geothermal Energy • Solar Energy • Wind Power • Onsite Wastewater Treatment Systems

20. Assignment 1 Prepare a 10-12 page paper on a sustainable practice. Due September 28th Present your findings to the class in a 10-15 minute powerpoint presentation during the week of October 4th
