Response to Review of 5th Submittal
The previous application for this project was returned as incomplete on 12/10/2021. The applicant is filing a
new application. DPR has provided a response to comments made by NCDEQ-DEMLR on July 6, 2021
because those comments have been incorporated into the plans to accompany the new application.
1. New hard copies for the Supplement-EZ Form, O&M Agreement Form and the High Density Deed
Restriction Document forms have been submitted with original signatures from the Applicant.
2. The Supplement-EZ Form has been revised to delete the fountain.
3. A hard copy of the Application with original signatures of the Applicant has been submitted.
4. An additional column was added to the Supplement-EZ Form to deal with impervious areas that do
not drain to an SCM.
5. The soil type composition calculation has been corrected so that areas in all calculations match.
6. The impervious areas and drainage areas have been corrected so that all forms and calculations
match.
7. A corrupted formula in the spreadsheet calculations for volume has been corrected.
8. Lines 7-9 on the Supplement-EZ Cover Page have been changed. The vegetated setbacks will
remain vegetated. Crossing the vegetated setbacks of Quarry Creek is necessary to reach the
development site. The Town of Granite Quarry requires 2 means of access for public safety reasons.
The original design of multi -culvert crossings was changed to bridges to minimize the placement of
built -upon area in the vegetated setback. Runoff from the Winding Creek Road bridge drains into an
existing wetland, travels about 110 feet through the wetlands and enters an existing vegetated
channel approximately 140 feet to Crane Creek. Runoff from the Emergency Access bridge
discharges at the edge of the vegetated setback to Quarry Creek. Both discharges must pass
through the vegetated setback in compliance with G.S. 143-214.7(b2)(2).
9. See response #4.
10. Lines 5 & 6 in the Drainage Area section of the Supplement-EZ Form have been corrected.
11. Lines 8 - 12 in the Drainage Area section of the Supplement-EZ Form have been corrected.

13. Lines 43 & 44 in the Wet Pond section of the Supplement-EZ Form have been corrected.
14. Lines 23 & 30 in the Sand Filter section of the Supplement-EZ Form have been corrected.
15. PDFs of the revised plans and calculations and all forms and applications and new fees are
being submitted as a NEW application because the previous application was returned as
incomplete.
