Transportation and Development Institute (T&DI)


The ASCE Orange County (OC) Branch Transportation and Development Institute (T&DI) Chapter was established in September 2016. The current OC T&DI evolved from OC Transportation Technical Group (TTG) with the addition of land development. OC T&DI’s missions are to:  

  • Advance the OC transportation and land development communities in the direction that is in line with the ASCE T&DI National’s objective.
  • Provide members with opportunities to share their knowledge and expertise in transportation engineering and land development that is relevant in the OC area.

OC T&DI aims to accomplish the missions through:

  • Technical lectures, specialty seminars and technical tours: Attendees who attend technical lectures and seminars are eligible to receive accredited Professional Development Hours (PDHs) applied towards the Continuing Education Program of the P.E. licensing renewal often required for professional registration in states outside California. Periodically, OC T&DI holds joint events with the OC Branch during branch general meetings. The OC Branch and the OC T&DI work together to provide continuing education events that are relevant to T&DI members.
  • Networking events that allow members to interact with other professionals and agencies in the transportation and land development fields of civil engineering.
  • OC T&DI regularly sends active OC branch members to T&DI Conference that is held on an annual basis across the country. When the attendee learns new ideas and finds interesting topic, he or she can share and present to our local Branch members.

If you would like to present your project at one of our monthly lectures, or if you have any topic that may be of interest to the members, please do not hesitate to contact any of the OC T&DI Board members with your questions or comments at [email protected]

So It Goes…

With the new fiscal year having begun in October, we felt this month’s President’s Column would be a good forum for our new presidents (Remi Candaele, ASCE OC Branch President; Ashlyn Alexander, ASCE OC YMF President) to introduce themselves and for me and YMF counterpart (Melissa Hilsabeck) to reflect on our respective terms as president of the OC Branch and OC YMF.  I hope that the Q&A that follows helps you get to know more about each of us.

Firmly entrenched in the midst of my career and fast approaching my 40th birthday, I have found myself thinking about legacies quite a lot lately.  One of the unique things about being president of the ASCE Orange County Branch is that the position affords the ability to see legacies at various stages of development: ones that have been cemented, ones whose seeds have just been planted, and everything in between.  In the ASCE Orange County Branch, I have noted some excellent examples of each over the past few months.

Finding the Words

I presume that if you’re reading this article, you probably became an engineer because your affinity for the language arts was not as strong as for math and sciences (assuming you even liked language arts at all).  While I personally enjoy writing and have been told that I am not terrible at it, I still find writing articles like the ones for this column to be challenging.  Newsletter articles offer a blank canvas to express your thoughts on a variety of topics, which can be overwhelming.
