Land use site assessment presentation 10.23.12

  1. 1. Trillium Hollow Site Assessment Joanne Delmonico, Rob Emanuel, Polly Helm October 23, 2012
  2. 2. Agenda• Reintroduction to the process• Base maps• Sector analysis maps• Climate• Q&A• Discuss next steps
  3. 3. Phases of Activity Last SpringNow Assessing community wishes and appreciations Assessing what the land can sustain Synthesis Design charette Living document & implementation
  4. 4. Site Assessment = Base Map + Sector Analysis
  5. 5. Base Map Sector Analysis
  6. 6. Trillium Hollow Base Maps • Neighborhood • Zoning • Boundaries • Underground Infrastructure • Shape of the land (slopes and flats)“A base map captures everything that is already on your chosen site. It includes buildings,borders, vegetation, pathways, driveways and utilities.”
  7. 7. BASE MAP – Neighborhood
  8. 8. BASE MAP – Zoning
  9. 9. BASE MAP – Boundaries
  10. 10. BM 2: Impervious surface
  11. 11. BASE MAP – Underground Infrastructure
  12. 12. BM3: unnamed stream “headwaters.”BM3: wetland & BM3: unnamedunnamed stream stream exiting into“headwaters.” daylight below the “bioswale.”
  13. 13. BASE MAP – Elevation Terrace #1 Terrace #2high = green; low = purple
  14. 14. BM 2: Terracing frombackslope throughclothesline area
  15. 15. BM 2: Terracing fromfront-slope to Plaza
  16. 16. BM 2: Drop off fromlast terrace to creekand lowest point onproperty.
  17. 17. Trillium Hollow Sector Analysis • Sunlight & Shade • Topography & Microclimate • Soil & Soil Moisture • Wildlife & Human Corridors • Climate Patterns“A sector analysis is a summary of the energies that affect the site and whichoriginate from different directions outside of it.”
  18. 18. SECTOR ANALYSIS – Sun and Shade Trillium Hollow Sector Analysis 1: Annual Solar Exposure
  19. 19. SECTOR ANALYSIS – Elevations (vegetation heights and types) Trillium Hollow Sector Analysis 2: Elevation & Tree CanopyDeepest blue = highest elevation objects Lightest blue = lowest elevation surfaces
  20. 20. SA 1: Marcia and Polly’s Deck, October 6, 11:30 AM
  21. 21. SA 1: October 20, 3:30 PM
  22. 22. SA2: Trees and shade
  23. 23. SECTOR ANALYSIS – Topography and Microclimate Trillium Hollow Sector Analysis 3: Contours & Microclimate
  24. 24. SECTOR ANALYSIS – Topography and Microclimate Trillium Hollow Sector Analysis 3: Contours & Microclimate
  25. 25. SECTOR ANALYSIS – Wildlife and Human Corridors Trillium Hollow Sector Analysis 4: Wildlife & Human Corridors
  26. 26. SA4: Deer on the backslope
  27. 27. SA4: Some other Trillium Hollow neighbors
  28. 28. SECTOR ANALYSIS MAP – Soil & Soil Moisture Trillium Hollow Sector Analysis 4: Soil Infiltration & Wetland
  29. 29. SA4: saturated soilsunder pathways,berm and part ofgarden.
  30. 30. SA4: TH construction (1997) & impact to soils
  31. 31. SA4: TH construction (1997) & impact to soils
  32. 32. SA4: TH construction (1997) & impact to soils
