At this time, the submission is not administratively complete and cannot be accepted for review in its current condition. Please provide the following submittal items within 30 calendar days (by close of business on 4/6/2023) so that we may accept the project and begin the review process, otherwise, the project will be returned as administratively incomplete.  2x hard copies of the Application Form (or pages) with the following corrections made (A complete application is required per 15A NCAC 02H .1043(3)(a)):  Part D2 – Please complete this information.  Part E4 – The stream index and classification number do not appear to be correct. This information can be found at the following address: https://experience.arcgis.com/experience/7073e9122ab74588b8c48ded34c3df55/ Please revise as needed.  Part E5 – The project density does not appear to be calculated correctly. For a project with existing BUA, the % BUA is calculated as \[New BUA\] / (\[Total Project Area\] – \[Existing BUA\]). Per the information in the table, \[New BUA\] = 624,858 sf, \[Total Project Area\] = 2,577,537 sf, & \[Existing BUA\] = 6,243 sf. This results in a percent BUA of 24.3% (624,858 sf / (2,577,537 sf – 6,243 sf) = 24.3%). NOTE: This is in excess of the maximum allowable %BUA for a low-density project. Please revise as needed.  1x original signed and notarized/sealed hard copy of Parts G & H of the Application. 2x original signed hard copies of this form are required and only one was provided (the other copy appears to be a photocopy).  2x hard copies of a construction sequence discussing how any future development on the project may be phased. This item is required per 15A NCAC 02H .1043(3)(g). The construction sequence does not need to be lengthy, just a brief description of how future development on the project (beyond what is shown on the plans) will be phased. If no future development is planned for the project, you can simply state that in the construction sequence. This item is different than the E&SC sequence of construction.  2x hard copies of official documentation showing the title and position of the signing official for the Applicant and showing that the Applicant organization is in good standing with the Secretary of State. These items are required per Part F7 of the Application and 15A NCAC 02H .1043(3)(b). NOTE: This is an administrative completeness review, not a detailed engineering review, there may be other issues that may be brought up during the engineering review. The following items were noted during the review, but do not need to be addressed for administrative completeness: - Untreated stormwater runoff cannot be directly discharged to a surface water (as appears to be the case with the culvert near Lots 1 & 111) it must be released at the edge of the vegetated setback and allowed to flow through the vegetated setback as dispersed flow (per 15A NCAC 02H .1003(4)(e)). - There appears to be excessive piping for this project to be considered as low-density (notably the pipes located between lots 14 & 15, 19 & 20, and 86 & 87). Per 15A NCAC 02H .1003(2)(c), vegetated conveyances should be used in these locations. If these items are received within the stipulated timeframe, we can accept the project and begin the review process. Once accepted, reviews under the Fast-Track permitting process can take up to 30 calendar days per statute (one of our two reviewer positions is currently vacant). 1 Hard copies should be mailed to the following address: For FedEx/UPS: Jim Farkas 512 N. Salisbury Street, Office 640M Raleigh, NC 27604 For USPS: Jim Farkas 1612 Mail Service Center Raleigh, NC 27699-1612 If you have any questions, please contact Jim Farkas at jim.farkas@ncdenr.gov or 919-707-3646.
