Subject: RE: Transportation SDCs
We can talk about water at your convenience. With regard to your transportation SDC issue, your adopted methodology does give credits for diverted/linked and pass-by trips. I am finishing up a SDC methodology update for the City of Willamina and we used PM peak hour trips for our unit of demand. Here are the ITE manual (version 10) trip generation characteristics for a Coffee/donut kiosk land use (ITE code 938):
As you can see, the observed PM peak hour vehicle trips are 83.33. However, this land use is given a 89% credit for pass-by trips yielding a net PMPHVT of 9.71. That is what you should be using for your SDC calculations. If this use is not a kiosk, you may want to look at ITE codes 936 or 937.

Steve – First, I would like to schedule a conversation about getting the water component back on track. Second, I was hoping to chat with you about the simple transportation SDC analysis below and get your opinion. I can fill you in on the reasoning and purpose later.

After a tiny bit of research tonight I'm quite positive this is correct. We are suppose to reduce PM peak hour trips by the percent of pass-by trips listed in Table b-9 for the type of land use. Every other city does so. The number G is using would be what an engineer uses to, say, size the drive through itself, for which EVERY trip is fundamentaly NEW. I might recommend PW be asked to confirm with Dyer and Donovan, and double check the impact this has had if it turns out to be an error. Not trying to stir the pot. Hope this helps.
