• 6th Largest County in Texas• Population at “build-out”

estimated to be 2.1 - 3.4 million

A very important question must be answered now:

Will the “economic engine” that has made Collin County what it is today be maintained – or left to grind to a halt?

Conclusions

The results of the travel demand modeling generally confirm that the Collin County Mobility Plan is not adequate to support populations of either 2.1M or 3.4M.

Specifically, there is not enough capacity in the transportation system for the projected demand.

Strategic Planning

12

So what can Collin County do to start planning strategically for transportation?

• Resist the urge to plan for tomorrow or even 2035. Think “BUILD- OUT” when planning.

• Develop an “un-restrained” build-out scenario

• Develop build-out plan with TxDOT, Cities, transit agencies and with COG’s assistance

• Start measuring all actions to determine if they contribute to build-out plan

Develop process for cities, TxDOT, transit agencies and NCTCOG to work together on build‐out planIn Process

Cities and County agree where LARS should go in order to maximize larger commercial development as opposed to neighborhood commercial

Next Steps

Currently Not Addressed

Work together to find routes through our fast‐growth county now in order to preserve ROW
