5 Agenda Changing the Lens of Analysis Implementation Challenges

6 Land Use Transportation

7 Space Efficiency

8 What is Transportation Level of Service (LOS)? Measures car congestion at signalized intersections Intersections are assigned an A F rating depending on how long vehicles are delayed at an intersection. Does not measure a location's vibrancy, walkability, bikeability, etc.

9 What is Vehicle Miles Traveled (VMT)? Measure of how far people will typically travel by vehicle Low VMT projects & areas: People don t have to travel by car as much or as far to get what they need High VMT projects & areas: People have to go far to get what they need People have few viable options other than to drive

10 Measure what you value LOS VMT F A A F

12 Implementation team Department of Public Works Planning, Building and Code Enforcement Long range planning Environmental team Housing Department Office of Economic Development City Attorney s Office Department of Transportation

13 VMT Mitigations Project Infrastructure Parking TDM

14 VMT Mitigations Project Project Density Land Use Diversity Project Design Affordable Housing

15 VMT Mitigations Infrastructure Internal pedestrian/bike network Accessibility to and quality of external pedestrian/bike network Neighborhood traffic calming improvements Accessibility to and quality of transit network

16 VMT Mitigations Parking Project parking supply Unbundled parking Internal bike facilities Bike parking Working parking pricing

17 VMT Mitigations TDM Transportation Management Associations Ride-sharing Telecommuting and alternative schedules Commute trip reduction marketing/education Car-sharing

20 Modernizing mitigation A demand-centered approach Oct. 29, 2018

22 A supply-based-system 22

23 A history of exactions for roadway supply L.A. County Master Plan of Roads, 1941 (via Michael Manville, Automatic street widening: Evidence from a highway dedication law. Journal of Transportation and Land Use, 2017.) 23

24 Problems (partial list) Cost of construction, operation, maintenance Personal transportation costs Reduced ability to travel by other modes Last one in issue Increased cost of infill (and hence rents) Reduced livability Degraded environment NIMBY opposition to infill Outcomes not consistent with policy 24

25 Roots of a more balanced, modern approach Employer-based TDM programs (1970s) Demand measures rather than supply Mitigation may or may not address VMT Arlington County, VA (1990) Mitigation requirements apply to buildings, run with the land Cambridge, MA (1998) Mitigation based on parking stalls requested Pasadena, CA (2014) Mitigation based on forecast VMT from development 25

26 Pasadena program Large developments: Must not exceed VMT per capita of 22.6 daily Must not exceed vehicle trips per capita of 2.8 daily Must not reduce service population located within one-quarter mile of levels 1 and 2 bicycle facilities below 31.7 percent Must not reduce the service population located within one-quarter mile of levels 1 and 2 of transit facilities below 66.6 percent Must not decrease the citywide Pedestrian Accessibility Score below 3.88 LOS addressed separately for high trip generators, mitigated through TDM. 26

30 Generic program The developer of an applicable project enters basic information use, size, and parking capacity being sought into an online tool or spreadsheet. The tool calculates the amount of mitigation required. This may be in terms of VMT or more simply in terms of TDM points. The applicant reviews the options available and the points for each, and selects enough measures to meet the requirement. The locality reviews the plan and includes it in the file of other building obligations that run with the land. The building owner implements the required measures. Periodically, the building owner recertifies that the required measures are still in place. Larger projects must provide more frequent and detailed reports, including outcomes. 30

31 Parking is key 31

32 Parking-based mitigation 32

33 Results (Pasadena) Adjustment in land use mix, resulting in a better balance Less pressure to reduce scale of projects Lower regulatory burden, especially on small projects Substantial burden in model development/operation Need for more data on TDM measures in combination 33
