1 The transportation and land use connection

2 A sustainable trend? 180% 160% 140% 120% 100% 80% 60% 40% 20% 0% Annual vehicle miles traveled US Population Road mileage We re driving more. Infrastructure can t keep up

3 Community Design Transportation Land Use

4 The transportation-land use relationship Density Diversity Design

5 Density Describes how closely land uses are placed to one another Higher density = closer proximity less distance traveled More efficient use of space Doubling density reduces vehicle travel by 38%

6 ¼ mile mile ¼ mile mile 3 dwelling units per acre = ~100 dwelling units 9 dwelling units per acre = ~280 dwelling units

7 Design How different uses/places relate to each other Buildings Street network Public spaces

9 Diversity Mix of uses Proximity between origins and destinations Generates local activity

20 Connectivity and corridors

21 Connectivity Short trips can be made on the local street network All trips must use the main arterial Good connectivity Poor connectivity

22 Networks create capacity

26 Getting it done: tools for implementation

27 Setting the vision

28 Overlays existing code Urban design overlay

29 Urban design overlay

30 Form-based code Emphasis on form, not use Relationships to the public realm (street)

31 Connectivity ordinances & access management standards

32 Impact fees & adequate public facility ordinances Can be used to fund on-site improvements, or Require construction of facilities

33 Density & parking bonuses Developer incentive Build street improvements Additional density/intensity, relaxed parking requirements, etc.

34 NW 54 th Street corridor in Miami typical existing 70 R.O.W.

35 70 R.O.W. enhanced Wider sidewalks with street trees Wide outside lane for larger vehicles and bicycles Removed center turn lane (except at major intersections) Can be implemented within the existing ROW

36 Redevelopment on one side Expanded ROW through developer easement Wider sidewalk addresses building facade Add bike lane and on-street parking

37 Redevelopment on both sides County to implement through formbased code ROW easement Building orientation FAR incentives Reduced parking requirements

38 Tag along projects Resurfacing Drainage Reconstruction/new construction

39 Isn t it expensive? The cost is incremental or minimal in terms of the overall construction costs for a new facility. Whit Clement, Virginia Secretary of Transportation
