Jeremy,
I approve your modification of the drainage area and accept your technical information supporting the design of the
wet detention basin. Good luck with this project.
Thanks,

Plan Modification Request
Good Afternoon Annette
I hope you are doing well. I would first like to thank you for allowing me to tag on to our meeting yesterday
morning with some additional questions regarding Briar Chapel, as it was greatly appreciated. As you may
recall, we discussed the proposed revisions to the site layout for a small area in Phase 4 of Briar Chapel that
will result in a net increase in the total number of lots and a net increase in the total impervious to a
previously permitted wet pond. In summary, the layout revisions take place entirely within a single pond
drainage area, and although the total impervious area to this wet pond will increase, the previously permitted
design is still valid without any structural modifications necessary. Please find the attached documentation
containing a letter explaining in detail the proposed layout revisions, a revised BMP supplement for the
affected wet pond, an exhibit showing the layout revisions, and supporting wet pond calculations
demonstrating the previously permitted facility can handle the increase in the total impervious area without
any structural modifications necessary.
You may also recall my mentioning yesterday that we are submitting to Chatham County a recombination
plat for these layout revisions. However, before approving the recombination plat, Chatham County is
requiring "approval" from the various agencies (NCDOT, NCDWQ, etc.) of these layout revisions.
Therefore, as we discussed yesterday, is there anyway we could receive an email approval of these revisions
so that we can forward to Chatham County to satisfy their requirement that NCDWQ approve the revisions?
If there is anyway we could receive an email approval by the end of this week, I would greatly appreciate it.
I am also copying Joseph on this email so that he is in the loop on these revisions because he has previously
done all the Express Review for Phase 4 of Briar Chapel. Also, I will also be sending a hard copy of the
attached documentation to you in the mail for your files.
As always, I appreciate your help on this project. If there is anything else you need to process this request,
please do not hesitate to contact me.
