It is the NCBRS' understanding that the Prospective Developer, Embrey Partners, LLC (Embrey) has applied to your agency for a permit to realign and restore a stream on the Brownfields Property. We support Embrey's restoration efforts and will continue to work with Embrey toward the successful redevelopment of the Brownfields Property. Please let us know if we can provide any additional information in support of this project. Sincerely, William L.
