1)Any stream classification on the plans would come from the technician drawing the plans. Sometimes they get it

wrong. I should have caught that. The correct classification is in my cover letter (C +).
2)The ESA is an old drained pond that is now a wetland. The purpose of the cross hatching and proposed safety

fence is to draw everyone’s attention to the area so they stay out of it. The special provisions are in the actual
contract, not the plans. Much of the environmental language will be similar to what you see on page 1A but
there will be more detail, including specific seeding blends/rates and such.
3)Mitigation to DWR is not required so the corps is the only regulatory agency that gets the email from EEP. I

request mitigation for maintenance projects at the same time the application is submitted so I don’t actually
have an acceptance letter (other Divisions may handle it differently). That’s never a problem since the amounts
needed are low. Huge TIP projects with 15,000 feet of impacts are a different story. The EEP letter is needed up
front in those cases to verify that they can handle what’s needed. I check the box on the PCN to let the Corps
know that mitigation is being requested. They get a copy of my email to EEP too.
4)F.3b – Well honestly I’ve never been asked to answer that question for maintenance projects. We are just kind

of upgrading an existing facility, not creating a new one. I really wouldn’t expect any new development because
of what we are doing, especially considering that much of the area falls within the FEMA Floodway. We are
undercutting the roadway to avoid a CLOMR.

Hope this help clarify things. Let me know if you have further questions.

Hi Heath,
Thanks for the erosion control plans. There are a few other items that need to be addressed.

I noticed that on Plan Sheets 18 and 19 (close ups of 9+30, and 62+59) the designer IDs the UTs as WS-IV;

CA+. Is that correct?

What is the environmentally sensitive area on Sheet 13? The notes say to see project special provisions, but I’m

not seeing the special provisions.

There is no mitigation acceptance letter from EEP.


Could you provide an answer to question F.3b. on page 9 of the PCN?

Try this one.

Wet pipes that remain perched due to excessive slopes are usually handled with dissipater pads in the
streambed. Failure to do so usually leads to blow holes. I usually include the bulleted language below just below the
impact table in the application cover letter but looks like I failed to do so this time for some reason. Guess I just felt like
mixing things up that day. Based on previous discussions with DOT Hydraulics and other regulators, it is believed that
once pipe slopes exceed about 6%, fish passage is not likely. That’s why we don’t try to bury pipes on a 10% grade. Let
me know if you have further questions.



Please note that all wet pipe slopes exceed 6% and need not be buried. These pipes may remain perched
after replacement due to excessive slope. If so, riprap energy dissipater pads will be placed in the stream
channel at the outlet of these pipes.

Hey Heath,
I’m not seeing the proposed erosion control measures you referenced in the application letter. Not saying they aren’t
there, just that I’m not finding them. Also, how does DOT typically handle pipe outlets that remain perched in terms of
preventing scour?
