Sue,
Good morning. I hope you are doing well.
As requested, I am sending you a copy of the stormwater plan and application for Fieldstone Phase 1 at High Hampton. I
have not attached copies of the supporting calculations and other documentation. I will be glad to send that
information if that is helpful.
This package is being submitted with the Resort Core stormwater today. I will send you a separate email with the same

Dear Ms. Lucas:
Please find enclosed the submittal for post construction stormwater permitting for a new subdivision
in the High Hampton Community in Jackson County, NC. This is a high density project located in a Tr+
waters, so post construction stormwater management is required.
With this letter, please find enclosed two copies of the stormwater management plans, supporting
calculations and narrative, completed permit application and signed operation and maintenance
agreement. Also, I have enclosed a CD with PDF files with all this information.
If you have any questions about this submittal or if you need more information, don't hesitate to
