  • 15. Structure of the CCM 3. Community Character Policies General Characteristics Application Appropriate Land Uses Appropriate Zoning Districts Building Types
  • 16. Structure of the CCM 3. Community Character Policies Design Principles Per Policy Block Length Lighting Access Parking Building Form (Mass, Service Area Orientation, Placement) Signage Connectivity Density/Intensity Landscaping
  • 17. T3 Suburban Neighborhood Maintenance • Moderate to deep setbacks • Informal landscaping • Shoulder and swale, likely no sidewalk • Larger lots and smaller building footprint • Moderate connectivity, often with curvilinear streets
  • 18. T4 Urban Neighborhood Maintenance • Shallow setbacks • Formal landscaping • Curb and gutter with sidewalk • Smaller lots and larger building footprint • High connectivity with linear streets, shorter block lengths and complete grid
  • 19. General Principles Overarching commitment to Sustainable Communities & Sustainable Development Complete Communities Housing & Neighborhoods Gentrification, Revitalization & Deterioration Historic Preservation Natural Resources Preservation Infill Development
  • 20. General Principles Mixed Use Centers & Economic Development Transportation Street Cross Sections & the Transect Stormwater & the Transect Transitions between Policies/Determining the Boundaries of Policies
  • 21. Conservation Policy Found in all Transect areas except T6 Downtown Preservation and remediation of environmentally sensitive land features
  • 22. Conservation Policy Floodplain Floodway Steep Slopes View sheds Ridgelines Unstable Soils Cedar Glades
  • 23. T2 Rural Low density residential; mix of housing where appropriate. Low connectivity Large setbacks are present Natural landscaping
  • 24. T3 Suburban Low to medium density residential, some mix of housing but are predominantly single-family Street pattern is usually curvilinear and has moderate connectivity Sidewalks are provided in centers, along corridors, and in newer subdivisions
  • 25. T4 Urban Medium density residential neighborhoods that contain a mix of housing Street pattern is usually a grid and has high connectivity Sidewalks widespread More formal landscaping, street trees

  • 32. Determine the appropriate policy Ex. T4 Urban Neighborhood Evolving applied to areas where The community has expressed an interest in “evolving” OR The following characteristics are present: High vacancy rates, High proportion of vacant land High potential for consolidation or subdivision of incongruous lots (little lot pattern) Incongruity between existing land use and zoning Proximity to centers or corridors and/or Age/condition of existing development
  • 33. Set boundaries for each policy In “Application” of each policy, “Commonly used boundaries include…”
  • 34. Determine “Special Policies” for each Policy Area Any unique features are outlined in the plan. Otherwise, the basic policy applies.
