Fundamental Issue: Policy Alignment

Targets

• Blueprinting governance

• Citizen planning

• Blueprinting performance

• Land Planning/Urban sprawl

• Air quality

• CO2

Misalignment

• Peripheral regulatory body

• Limited options

• Limited incentives

• Limited enforcement power

• Constrained mandate

The Road From Current to Blueprint…

The Metropolitan

Transportation Plan (MTP)

(2035)

Now 2050

“[The Blueprint Process was designed] to produce a vision for the

region that had sufficient technical grounding and political support

to serve as the basis for SACOG’s next Metropolitan Transportation

Plan.” (McKeever, pg 4, 2009)

Take Aways

• Blueprinting is useful, but not the right vehicle to initiate

real change

• Blueprinting is not regional – in the SACOG case, it was 6

separate counties blueprinting their future and then a

weaving in of those aspirations –

• BUT, in the end, decisions centered on obvious choices

• State to regional to local actions dilute responsibility; no

link to accountability

• Our path to total transportation GHG reductions (in the

20-30 yr horizon) depends on eliminating growth outside

the major cities 37

Other steps

• Adding in fiscal elements (e.g., schools)

• Reconceptualizing local govt’s role

• Modifying CEQA regs

• Bringing in EJ aspects
