Assessment of Wastewater Options Decision Matrix Criteria Decision Matrix Results Alternative Percentage Weighting Environmental Impact 30% Cost 30% Feasibility 20% Creativity 20% Alternative Environmental Impact CostFeasibilityCreativityTotal Conventional Septic 0.90.60.30.452.25 Presby System 0.3 0.150.3 1.05 Wetlands Treatment 0.6 0.450.31.95

19. 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

20. 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

21. 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

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

23. 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
