  4. Project Description

  5. Project Description • 66 Acres • 22 Estate Size Homes • 1-2 Acre Lots • ± 33 Acre Community Space • High Efficiency • Low Environmental Impact

  6. Existing Site Proposed Development

  7. Design Requirements Objectives • Develop 3 Wastewater Treatment Options • Develop Stormwater Management Plan • Incorporate Greywater Treatment and Reuse • Wetland Habitat Area • Community Recycling Program • Design Trail Around Site

  8. Preliminary Feasibility Study • Location • Zoning • Utilities • Transportation • Site Characteristics

  9. Environmental Site Assessment • Site Reconnaissance • Current and Past Use • Tax Information • Other Concerns • Interviews • Josh Reed – Property Owner • Hancock County Assessor’s Office

  10. Codes & Regulations Regulation Entities • Hancock County • Conservation Subdivision • IDNR • LEED • 10 State Standards • AASHTO

  11. LID Design Options

  12. Preliminary Site Plan • Designed According to Hancock County • Will Meet R-1 Zoning • 1-2 Acre Lots for Adequate Septic

  13. Preliminary Site Plan • In Contact with Mike Dale - Planning Dept • Use Natural Lay of Land to Reduce Cut and Fill in Roadway • Roundabout Designed to Standards (TFHDC)

  14. Geotechnical Analysis • Wildcat Dynamic Cone Penatrometer • Tube Samples (6” &3’)

  15. Laboratory Analysis of Samples • Unconfined Compression Test (ASTM D2166) • Atterberg Limits (ASTM D4318) • Particle Size Analysis (ASTM D422)

  16. Assessment of Wastewater Options • 3 Options Considered Conventional Septic System Presby Treatment System Wetlands Treatment

  17. Assessment of Wastewater Options • Decision Matrix Criteria • Decision Matrix Results

  18. Hydraulics and Hydrology • Design for 100-yr flood • Route stormwater through wetlands • Size pipes to control flooding • Design water quality trenches • Promote natural overland flow Existing vs Proposed 100-year Storm Routing

  19. Wetlands • Treat 170 acres • Design wet pond to allow for sediment settling/quality volume • Research vegetation for the wetlands • Design outlet structure that controls 100-year flood

  20. Erosion Control Plan • Minimize sediment runoff into Miller Ditch • Minimize cut and fill on-site: 680cy cut • Reduce soil that leave site via truck tires

  21. LID/Conservation Highlights • 50% Community Space • 20 Lots front community space • Enviro-Septic Wastewater Treatment • Density meets maximum requirement

  22. Highlights • 22 Lots, 1-2 Acres Each • Site Layout/Roadway Design • Sustainable LID Designs for: Wastewater Greywater Stormwater • $440,000 Cost Estimates for Design/Construction/Lifecycle
