maintain the stormwater system. 11/30/2010 NOV issued for failure to maintain the stormwater system. 2/1/2013 DEMLR was notified that the project was under foreclosure,and had been acquired by D.R.Horton,Inc. 3/8/2013 Compliance inspection: Stormwater system was not complete,was not certified,was not being maintained,and a permit transfer was needed. 4/30/2013 D.R.Horton was issued a new permit,SW8 130412,to replace 5W8 060354 after unsuccessful attempts to contact the SW8 060354 for a permit transfer. No design changes were made. The permit was maintained under the 1995 rules(1.0 inch). 5/16/2014 Adjacent permit,SW8 131207 for Phase 4 was issued. (Phase 4 is across River Road directly on the river.) 12/6/2016 Partial Certification(Phase 3 Pond 2 only) 6/15/2017 An application was submitted to change the designs of Phase 3 Pond 4&Phase 3 Pond 6. 8/24/2017 During the review,DEMLR found that the project's plans did not match the configuration on Google Earth,and so a site inspection was conducted. There are ponds not built per the plan,and there is unpermitted construction. It also appears that unpermitted lots have been sold without recorded deed restrictions,and the impacted ponds have not been designed to accommodate full build-out from those lots. 10/12/2017 1.Modification Issued: The permit was modified to change the designs of Phase 3 Pond 4&Phase 3 Pond 6. (All impervious area was designed at 1.5 inches per the 2017 rules.) 2.Second Notice of Inspection Issued: The modification issued on this date DOES NOT address the non-compliant items in the August 24,2017 inspection. A response to the August 24,2017 inspection was due on September 25,2017,but has not been received. 8/9/2018 Meeting between Kelly Johnson(DEMLR),Anthony Mills(DR Horton),and Tim Clinkscales,PE. -The permit was in-house for a modification,but the application did not include all items that were needed. It was determined that Ph3/Pond 5 would be modified under the current application and that Ph3/Pond 4,Ph3/Pond 6,and Phl/Pond 3 would be modified under a future modification. -These ponds were reportedly designed at 4,500sf/lot,deed restrictions were recorded at 4,500sf/lot(BK745/PG0986),but the permit requires 4,000sf/lot. -It was unclear if Ph3/Pond 2 needed to be modified as well. There was inconsistent design data in the application package. -The Townhomes/Phase 2 have been given 4,SUOsf/lot for each residence(not building). But,these homes are sold without land. The owners cannot build outside of their building,and so DEMLR does not require deed restrictions in this situation. -The project also needed maintenance previously identified,and the ponds need to be certified. 10/16/2018 Permit modification for Ph3/Pond 5. This pond has been modified to move it from outside Keekle Loop to inside Keekle Loop 1/29/2019 An incomplete application was submitted on 1/28/19 to change the designs of Ph1/Pond 3,Ph3/Pond 2,Ph3/Pond 4,and Ph3/Pond 6. It was returned. 3/14/2019 NOV issued for failure to construct per the plan,failure to certify the system,failure to provide deed restrictions,and failure to maintain the system. 10/7/2019 -Permit modification submitted on 3/21/19 for Ph1/Pond 3,Ph3/Pond 2,Ph3/Pond 4,and Ph3/Pond 6. See Attachment B for details. -Permit Correction:Corrected the drainage area for Ph3/Pond 2. The acreage had been incorrectly converted from square feet. Permit Correction: For Phase 1/Pond 1,there are now 59 lots at 4,500sf which totals 265,500sf. Since there are 98,446sf of road and the pond holds 368,082sf there is a"future"allocation of 4,136sf. -Permit Correction: Phase 3/Pond 5: Lot 3272 was converted to open space and is no longer a lot in the subdivision. There are now 36 lots draining to this pond which corresponds to the allocated 162,000sf of impervious for lot area. -Plan sheets that make up the permitted set: Approved 4/30/13: Cover,SW-1,SW-2,SW-3,SW-5(Partially replaced by 10/7/19 plans.

Built upon area has the same meaning as G.S. 143- 214.7, as amended. a. All runoff on the lot must drain into the permitted system. This may be accomplished through providing roof drain gutters, which drain to the street, grading the lot to drain toward the street, or grading perimeter swales and directing them into the pond or street. Lots that will naturally drain into the system are not required to provide these measures. h. Built-upon area in excess of the permitted amount will require a permit modification. 17. A copy of the recorded deed restrictions must be submitted to the Division within 30 days of the date of recording the plat, and prior to selling lots. The recorded copy must contain all of the statements above, the signature of the Permittee, the deed book number and page, and the stamp/signature of the Register of Deeds. 18. Prior to transfer of the permit, the stormwater facilities will be inspected by DEMLR personnel. The facility must be in compliance with all permit conditions. Any items not in compliance must be repaired or replaced to design condition prior to the transfer. Records of maintenance activities performed to date will be required. 19. Decorative spray fountains will be allowed in the stormwater treatment system, subject to the following criteria: a. The fountain must draw its water from less than 2' below the permanent pool surface. b. Separated units, where the nozzle, pump and intake are connected by tubing, may be used only if they draw water from the surface in the deepest part of the pond. c.

Land Holdings II,LLC as SW8 060354. 7/14/2010 NOV issued for failure to maintain the stormwater system. 11/30/2010 NOV issued for failure to maintain the stormwater system. 2/1/2013 DEMLR was notified that the project was under foreclosure,and had been acquired by D.R.Horton,Inc. 3/8/2013 Compliance inspection: Stormwater system was not complete,was not certified,was not being maintained,and a permit transfer was needed. 4/30/2013 D.R.Horton was issued a new permit,SW8 130412,to replace SW8 060354 after unsuccessful attempts to contact the SW8 060354 for a permit transfer. No design changes were made. The permit was maintained under the 1995 rules(1.0 inch). 5/16/2014 Adjacent permit,SW8 131207 for Phase 4 was issued. (Phase 4 is across River Road directly on the river.) 12/6/2016 Partial Certification(Phase 3 Pond 2 only) 6/15/2017 An application was submitted to change the designs of Phase 3 Pond 4&Phase 3 Pond 6. 8/24/2017 During the review,DEMLR found that the project's plans did not match the configuration on Google Earth,and so a site inspection was conducted. There are ponds not built per the plan,and there is unpermitted construction. It also appears that unpermitted lots have been sold without recorded deed restrictions,and the impacted ponds have not been designed to accommodate full build-out from those lots. 10/12/2017 1.Modification Issued: The permit was modified to change the designs of Phase 3 Pond 4&Phase 3 Pond 6. (All impervious area was designed at 1.5 inches per the 2017 rules.) 2.Second Notice of Inspection Issued: The modification issued on this date DOES NOT address the non-compliant items in the August 24,2017 inspection. A response to the August 24,2017 inspection was due on September 25,2017,but has not been received. 8/9/2018 Meeting between Kelly Johnson(DEMLR),Anthony Mills(DR Horton),and Tim Clinkscales,PE. -The permit was in-house for a modification,but the application did not include all items that were needed. It was determined that Phi/Pond 5 would be modified under the current application and that Ph3/Pond 4,Ph3/Pond 6,and Phi/Pond 3 would be modified under a future modification. -These ponds were reportedly designed at 4,500sf/lot,deed restrictions were recorded at 4,500sf/lot(BK745/PG0986),but the permit requires 4,000sf/lot. -It was unclear if Ph3/Pond 2 needed to be modified as well. There was inconsistent design data in the application package. -The Townhomes/Phase 2 have been given 4,500sf/lot for each residence(not building). But,these homes are sold without land. The owners cannot build outside of their building,and so DEMLR does not require deed restrictions in this situation. -The project also needed maintenance previously identified,and the ponds need to be certified. 10/16/2018 Permit modification for Ph3/Pond 5. This pond has been modified to move it from outside Keekle Loop to inside Keekle Loop 1/29/2019 An incomplete application was submitted on 1/28/19 to change the designs of Ph1/Pond 3,Ph3/Pond 2,Ph3/Pond 4,and Ph3/Pond 6. It was returned. 3/14/2019 NOV issued for failure to construct per the plan,failure to certify the system,failure to provide deed restrictions,and failure to maintain the system. 10/7/2019 -Permit modification submitted on 3/21/19 for Ph1/Pond 3,Ph3/Pond 2,Ph3/Pond 4,and Ph3/Pond 6. See Attachment B for details. -Permit Correction:Corrected the drainage area for Ph3/Pond 2. The acreage had been incorrectly converted from square feet. Permit Correction: For Phase 1/Pond 1,there are now 59 lots at 4,500sf which totals 265,500sf. Since there are 98,446sf of road and the pond holds 368,082sf there is a"future"allocation of 4,136sf. -Permit Correction: Phase 3/Pond 5: Lot 3272 was converted to open space and is no longer a lot in the subdivision. There are now 36 lots draining to this pond which corresponds to the allocated 162,000sf of impervious for lot area. -Plan sheets that make up the permitted set: Approved 4/30/13: Cover,SW-1,SW-2,SW-3,SW-5(Partially replaced by 10/7/19 plans.

I will place by responses in red. I just want to make sure we get back what you need and can turnaround in quick order. If I am reading correctly,they are very minor comments. 1) Modifications are proposed for four ponds: a) Phase 1/Pond 3: Please submit a second drainage area plan. (We received one for Phase 3A Section 2B, but I believe that that is the one for Phase 3/Pond 5?) Another copy to be provided Done. b) Phase 3/Pond 2: i) Please submit the O&M Agreement. Such to be provided Done. ii) Please check the elevation of the weir at the temporary pool. From the calculations and the supplement, it appears to be at 14.0ms1. There is an opening above the drawdown orifice at 13.85ms1. After looking over the pond information,you are correct, 13.85 is the elevation, all the documents will be reflected to such, this was also part of the partial certification placed in the package. .l didn't receive the calculations or supplement for this item. I am not sure if you are saying that this also impacted the partial certification? c) Phase 3/Pond 4: i) 2017 Rule: (1) 5/20/19 Letter: The impervious area increased and so this pond should be designed under the 2017 Rule. But, it appears that this project uses the 2008 forebay percentage, 18-22%of the whole permanent pool. Please ensure that the pond is designed to a single set of regulations. Since the pond is constructed, please provide justification if the forebay is too big. [.1053(5)(a)] 1 (2) 6/4/19 Response: The pond was done under the 2008 rules but now under the 2017 rules, since done multiple times, sent the wrong spreadsheet depicting the 2008 rules before, submitted the 2017 rule spreadsheet along with the supplement. We are below 20%for the forebays. (3) 8/2/19: Please also submit the 2017 O&M. Will provide, my question, this means all other items addressed and good on this pond Done. 2) Attachment B: a) Potential Typos: i) Phase 1/Pond 1: (1) 5/20/19 Letter: Please double check the data for Ph1/Pond 1 (which isn't being modified in this modification). It shows that there are 63 lots(1-7, 130-154& 156-186)at 4,500sf/lot. That totals 283,500sf for the buildings/lots. However,the buildings/lots in the Attachment B shows only 269,636st? (2) 6/4/19 Response: The Attach B updated,I can only go by as-built information and walking the site,the impervious numbers for Phase 1 Pond 1 and 2 were based on permit approved on 4/30/13 by Cape Fear Engineering. I have placed the record-drawings that show the break line for the grades and storm drainage to these two ponds,these are the impervious numbers provided in the chart. Both building areas are less than in the permit. Based on all lots having 4500 sf per lot in the neighborhood besides the ones we have modified,I cannot see where the 4/30/13 numbers were originated but again shown less than shown for the buildings/lots. In the chart,the numbers in parenthesis are the new numbers,have been added such for the future to make the total the same. For this phase,the actual building impervious is 265,000sf which is below the 269,636sf,therefore the ponds are sized for the impervious that are draining toward it. (3) 8/2/19: There are now 59 lots at 4,500sf which totals 265,500sf. Since there are 98,446sf of road and the pond holds 368,082sf there is a"future"allocation of 4,136sf. I will document this as a correction to Phase 1/Pond 1. Question, we are good on this pond as well,you are updating the permit to reflect the minor change. This has beet documented as a correction. See the attached Excel File,Attachment D Line 17. Done. ii) Phase 3/Pond 5: (1) 5/20/19 Letter: Please double check the data for Ph3/Pond 5 (which isn't being modified in this modification). It shows that there are 36 lots (3231-3272)at 4,500sf/lot. However,this appears to be 42 lots. Attachment B shows that there is 162,000sf of buildings/lots for this pond but if there are 42 lots at 4,500sf/lot would be 189,000sf? (2) 6/4/19 Response: Mistake on lot numbering on last submittal,the same number of lots which is 36 drain to the pond,Lots 3256-3260 not part of this pond drainage area. (3) 8/2/19: If Lots 3231-3255 and 3261-3272 drain to the pond,that appears to be 37 lots and 166,500sf total rather than the 162,000sf allocated to buildings/lots?Lot 3272 is the lot that was converted back to open space therefore no Lot 3272 and 36 lots in this area. Question,all other items addressed and good on this pond. This has been documented as a correction. See the attached Excel File,Attachment D Line 17. Done. 3) Plans in Full Set: a) Phases,Lots,and Lot Numbers: i) 5/20/19 Letter: Please ensure that all of the phases/sub phases are shown on the plans so that Lot 1 in Phase 1 can be differentiated from Lot 1 in Phase 3. For instance, 10222 Hawkeswater Blvd should be an additional lot next to Lot 5 below,but it is not on the plans. I do not see a more recent plan sheet for this area. The deed restrictions also do not list Lots 4 or 5 for Phase 3 Pond 1. It is unclear if these lots were renumbered or if they were not included in the deed restrictions. There may be other examples. 2 VN tkit `+..0 1 • i ' ''r ..v::aim f - - . . . , rA 1 61A 4,..L. :„.2...:_,:: ::.....-fA-: e ,%,7, 7.'1 ' \_ '...t.-4."-.:,-r Ai .yl.:+ri� ....1••t }t s b) 6/4/19 Response: Besides the areas that DR Horton has developed, in which lot numbers are consistent with the phase included, all other lot numbers are in the 3/21/19 package,I have provided the record drawings for Phase lA(pre)DR Horton that shows lot numbers,these areas were permitted with the lots provided in the earlier submittals. We verified to place in Attachment B. We are also updating the ponds to make them match the parameters of the 4/30/13 permit. c) 8/2/19: At the 3/21/19 meeting,we went through all of the plan sets that had been previously permitted and made a list of all of the previously-permitted plans. The plan inserted above was one of the ones that was to continue to be permitted. It was the sheet where part of the sheet was to be replaced by a more recent version,and we circled the area to continue to be permitted in red. This area is in red. 10222 Hawkeswater blvd is not on that plan. All of the lots,regardless of whether or not DR Horton developed them,need to be on the plan and their lot numbers need to match the deed restricted lot numbers. If you would like to make a file review appointment to go through the plans that we decided not to bring forward and see if one was left out,please contact me. Will look over this to verify lot numbers. What did you find? 4) Inspection: The ponds were inspected on May 24,2019. All ponds have been constructed per the plan. Three ponds, Phl/Pond 3, Ph3/Pond4,and Ph3/Pond6,were still being used as sediment basins. They had eroding slopes and sediment accumulating in the forebay, and will need to be cleaned out once the E&SC is closed.Noted Done. If possible,verify the simple questions, so we can close out the permit.

I will place by responses in red. I just want to make sure we get back what you need and can turnaround in quick order. If I am reading correctly,they are very minor comments. 1) Modifications are proposed for four ponds: a) Phase 1/Pond 3: Please submit a second drainage area plan. (We received one for Phase 3A Section 2B, but I believe that that is the one for Phase 3/Pond S?) Another copy to be provided b) Phase 3/Pond 2: i) Please submit the O&M Agreement. Such to be provided 3 ii) Please check the elevation of the weir at the temporary pool. From the calculations and the supplement, it appears to be at 14.0ms1. There is an opening above the drawdown orifice at 13.85ms1. After looking over the pond information,you are correct. 13.85 is the elevation, all the documents will be reflected to such.this was also part of the partial certification placed in the package c) Phase 3/Pond 4: i) 2017 Rule: (1) 5/20/19 Letter: The impervious area increased and so this pond should be designed under the 2017 Rule. But, it appears that this project uses the 2008 forebay percentage, 18-22% of the whole permanent pool. Please ensure that the pond is designed to a single set of regulations. Since the pond is constructed, please provide justification if the forebay is too big. [.1053(5)(a)] (2) 6/4/19 Response: The pond was done under the 2008 rules but now under the 2017 rules, since done multiple times, sent the wrong spreadsheet depicting the 2008 rules before, submitted the 2017 rule spreadsheet along with the supplement. We are below 20%for the forebays. (3) 8/2/19: Please also submit the 2017 O&M. Will provide, my question,this means all other items addressed and good on this pond • 2) Attachment B: a) Potential Typos: i) Phase 1/Pond 1: (1) 5/20/19 Letter: Please double check the data for Phl/Pond 1 (which isn't being modified in this modification). It shows that there are 63 lots(1-7, 130-154& 156-186)at 4,500sf/lot. That totals 283,500sf for the buildings/lots. However,the buildings/lots in the Attachment B shows only 269,636sf? (2) 6/4/19 Response: The Attach B updated,I can only go by as-built information and walking the site,the impervious numbers for Phase 1 Pond I and 2 were based on permit approved on 4/30/13 by Cape Fear Engineering. I have placed the record-drawings that show the break line for the grades and storm drainage to these two ponds,these are the impervious numbers provided in the chart. Both building areas are less than in the permit. Based on all lots having 4500 sf per lot in the neighborhood besides the ones we have modified, I cannot see where the 4/30/13 numbers were originated but again shown less than shown for the buildings/lots. In the chart,the numbers in parenthesis are the new numbers,have been added such for the future to make the total the same. For this phase,the actual building impervious is 265,000sf which is below the 269,636sf,therefore the ponds are sized for the impervious that are draining toward it. (3) 8/2/19: There are now 59 lots at 4,500sf which totals 265,500sf. Since there are 98,446sf of road and the pond holds 368,082sf there is a"future"allocation of 4,136sf. I will document this as a correction to Phase 1/Pond 1. Question,we are good on this pond as well,you are updating the permit to reflect the minor change. I will update the permit. ii) Phase 3/Pond 5: (1) 5/20/19 Letter: Please double check the data for Ph3/Pond 5 (which isn't being modified in this modification). It shows that there are 36 lots(3231-3272)at 4,500sf/lot. However,this appears to be 42 lots. Attachment B shows that there is 162,000sf of buildings/lots for this pond but if there are 42 lots at 4,500sf/lot would be 189,000sf? (2) 6/4/19 Response: Mistake on lot numbering on last submittal,the same number of lots which is 36 drain to the pond, Lots 3256-3260 not part of this pond drainage area. (3) 8/2/19: If Lots 3231-3255 and 3261-3272 drain to the pond,that appears to be 37 lots and 166,500sf total rather than the 162,000sf allocated to buildings/lots? Lo 3272 is the lot that was converted back to open space therefore no Lot 3272 and 36 lots in this area. Question, all other items addressed and good on this pond. OK,just please put that in the submittal letter. 3) Plans in Full Set: a) Phases, Lots,and Lot Numbers: i) 5/20/19 Letter: Please ensure that all of the phases/sub phases are shown on the plans so that Lot 1 in Phase 1 can be differentiated from Lot 1 in Phase 3. For instance, 10222 Hawkeswater Blvd should be an additional lot next to Lot 5 below,but it is not on the plans. I do not see a more recent plan sheet for this area. The deed restrictions also do not list Lots 4 or 5 for Phase 3 Pond 1. It is unclear if these lots were renumbered or if they were not included in the deed restrictions. There may be other examples.

'' • --� � � -_ - ' y _� • • � ; - j 'y. ,. -� .�,, +.:=ram' • 7------N, - ' , t.--:...'.- - t • b) 6/4/19 Response: Besides the areas that DR Horton has developed, in which lot numbers are consistent with the phase included,all other lot numbers are in the 3/21/19 package, I have provided the record drawings for Phase lA(pre) DR Horton that shows lot numbers,these areas were permitted with the lots provided in the earlier 5 submittals. We verified to place in Attachment B. We are also updating the ponds to make them match the parameters of the 4/30/13 permit. c) 8/2/19: At the 3/21/19 meeting,we went through all of the plan sets that had been previously permitted and made a list of all of the previously-permitted plans. The plan inserted above was one of the ones that was to continue to be permitted. It was the sheet where part of the sheet was to be replaced by a more recent version,and we circled the area to continue to be permitted in red. This area is in red. 10222 Hawkeswater blvd is not on that plan. All of the lots,regardless of whether or not DR Horton developed them, need to be on the plan and their lot numbers need to match the deed restricted lot numbers. If you would like to make a file review appointment to go through the plans that we decided not to bring forward and see if one was left out, please contact me. Will look over this to verify lot numbers. Thank you. 4) Inspection: The ponds were inspected on May 24, 2019. All ponds have been constructed per the plan. Three ponds, Ph1/Pond 3,Ph3/Pond4, and Ph3/Pond6,were still being used as sediment basins. They had eroding slopes and sediment accumulating in the forebay, and will need to be cleaned out once the E&SC is closed. Noted If possible,verify the simple questions, so we can close out the permit.

Like previous sections that were modified, amount shown in chart we are now designing for the 1.5"storm. The project is within a drainage basin which drains to the Cape Fear River. The receiving stream is the Brunswick River (SC). The runoff will be conveyed into the wet detention ponds via a storm drainage system. The runoff will be controlled in the ponds through the use of outlet structures to meet the pre/post requirements of Brunswick County. The impervious area was calculated by taking into the account the roadways, sidewalks and single family lots. PROPOSED IMPROVEMENTS The stormwater will be conveyed to the wet detention ponds via a piped underground storm system. The ponds will discharge to the existing wetland areas onsite.The ponds have been designed to meet the State required minimum 1.5"runoff temporary storage volume at 90%TSS removal. Please find all reference material and stormwater calculations in the following pages of this report. Note that some calculations have also been located on the plans for easy reference during construction. DESIGN METHOD Hydrologic calculations have been performed utilizing HydroCAD version 10.0 software which employs the USDA SCS Method. The Type-Ill 24-hour storm rainfall depth has been taken from the Brunswick County Storm Water Management Manual. Curve Number(CN)and Time of Concentration(TOC)calculations have been performed in accordance with the USDA TR-55 manual,with a minimum TOC of 5 minutes. Hydrologic Soil Group Classifications have been taken from the USDA Web Soil Survey. Precipitation data has been taken from the Brunswick County Storm Water Management Manual. Storm conveyance calculations have been performed utilizing the Rational Method within Carlson Hydrology 2016 which employs the FHWA Method for HGL cong, hris.

Phase 2 will consist of 17.7 acres located within the Hawkeswater at the River development off of previously constructed Morecamble Blvd and behind Belville Elementary School. The development is off NC 133 just outside of Leland. Phase 2 consists of 84 multi-family units on the 17.7 acres. The pond shown is sized for 25.12 acres in permit SW8 060354MOD,this is labeled as Pond#2,Phase 3. The pond was sized using the same criteria shown in the approved permit, the future development will consist of single family lots that will submitted for approval upon construction documents being produced. The project is within a drainage basin which drains to the Cape Fear River. The receiving stream is the Brunswick River(SC). The runoff will be conveyed into the wet detention pond via a strorm drainage system. The runoff will be controlled in the ponds through the use of outlet structures for primary control and spillways for greater rainfall events. The impervious area was calculated by taking into the account the roadways, sidewalks, multi-family units,amenity center and future single family lots. In addition to this requirement,they will be designed to handle the pre/post requirements from Brunswick County. MAINTENANCE Contractors shall be responsible for periodic inspection and maintenance of all indicated erosion control devices in accordance with the plans and specifications. In addition, inspection and any necessary maintenance will be required immediately following any significant storm event. Sediment will need to be removed from behind silt fencing as described on the Erosion Control Plan. Vegetative cover will be fertilized and reapplied as necessary to promote a vigorous stand.

This phase is located within the Hawkeswater at the River development off of previously constructed Hawkeswater Blvd. The development is on Highway 133 approximately 0.85 miles south of the intersection of Highway 76 and Highway 133. Phase 3a Section 2C consists of 60 residential lots with associated streets and sidewalks. This section of the project drains to two proposed stormwater wet ponds(Pond #4 and Pond#6),which were previously permitted under SW8 130412 which is to be modified per this submittal. The proposed permit modification is due to a change in drainage area and built upon area for the two proposed ponds. The proposed permanent pool elevations remain the same as previously permitted. Pond 34 was previously permitted as"Pond#4 Phase 3"and Pond#6 was previously permitted as"Pond#6 Phase 3". The project is within a drainage basin which drains to the Cape Fear River. The receiving stream is the Brunswick River (SC). The runoff will be conveyed into the wet detention ponds via a storm drainage system. The runoff will be controlled in the ponds through the use of outlet structures to meet the pre/post requirements of Brunswick County. The impervious area was calculated by taking into the account the roadways,sidewalks and single family lots. PROPOSED IMPROVEMENTS The stormwater will be conveyed to the wet detention ponds via a piped underground storm system. The ponds will discharge to the existing wetland areas onsite.The ponds have been designed to meet the State required minimum 1.5"runoff temporary storage volume at 90%TSS removal. Please find all reference material and stormwater calculations in the following pages of this report. Note that some calculations have also been located on the plans for easy reference during construction. DESIGN METHOD Hydrologic calculations have been performed utilizing HydroCAD version 10.0 software which employs the USDA SCS Method. The Type-III 24-hour storm rainfall depth has been taken from the Brunswick County Storm Water Management Manual. Curve Number(CN)and Time of Concentration(TOC)calculations have been performed in accordance with the USDA TR-55 manual,with a minimum TOC of 5 minutes. Hydrologic Soil Group Classifications have been taken from the USDA Web Soil Survey. Precipitation data has been taken from the Brunswick County Storm Water Management Manual. Storm conveyance calculations have been performed utilizing the Rational Method within Carlson Hydrology 2016 which employs the FHWA Method for HGL computations.

Horton's Address: 131 Racine Drive,Suite 201,Wilmington,NC 28403 FOURTH AMENDMENT TO DECLARATION FOR HAWKESWATER AT THE RIVER SUBDIVISION This Fourth Amendment to Declaration for Hawkeswater at the River Subdivision(this"Fourth Amendment")is made this Al si day of siwunit"( ,2019,by D.R.HORTON,INC.,a Delaware corporation,hereinafter roftimd to as"Horton." Horton states and declares as follows: A. Hawkeswater I, Development, Inc., a North Carolina corporation, Hawkeswater II Development,Inc.,a North Carolina corporation,Hawkeswater III Development,Inc.,a North Carolina corporation,and Riverside Land Holdings,LLC,a North Carolina limited liability company(collectively, the "Original Declarant") previously made that certain Declaration of Covenants Conditions and Restrictions for Hawkeswater at the River Subdivision recorded in Book 2745 Page 986, Brunswick County Register of Deeds,as modified by:(i)that First Amendment to the Declaration of Hawkeswater at the River Subdivision of record at Book 3380 Page 1230,Brunswick County Register of Deeds;(ii)that Annexation Declaration for Hawkeswater at the River Subdivision of record at Book 3493 Page 659, Brunswick County Register of Deeds(the"Annexation Declaration");(iii)that Second Amendment to the Declaration of Hawkeswater at the River Subdivision of record at Book 3550 Page 465, Brunswick County Register of Deeds; and(iii)that Third Amendment to the Declaration of Hawkeswater at the River Subdivision of record at Book 4113 Page 749,Brunswick County Register of Deeds(collectively, as amended and restated,the"Declaration"). B. All of the real property currently subject to the Declaration(the"Subject Property")was originally owned and held by the Original Declarant for the purpose of developing it into Hawkeswater at the River Subdivision(the"Subdivision"). C. All of the Subject Property was conveyed by the Original Declarant to trustees for the benefit of Cooperative Bank,a North Carolina bank,by Deeds of Trust of record at Book 2579 Page 889, Book 2605 Page 1340,Book 2606 Page 37,Book 2606 Page 72 and Book 2606 Page 106,Brunswick County Registry(collectively,the"Development Loan Deeds of Trust"),as collateral for a loan or loans, the proceeds of which were to be used in the development of the Subdivision (collectively, the "Development Loan"). Subsequently,all of the assets of Cooperative Bank,including the Development Loan and the Development Loan Deeds of Trust,were acquired by First Bank,a North Carolina Bank. _ JUN042019 BY; �__._ PffiJ(U'iLWff)lki!IJI!ii 155 • Cl 19 Deeds Pape z or a ' Subsequent to that acquisition,foreclosure proceedings were instituted under all of the Development Loan Deeds of Trust,which proceedings are of record at 11-SP-1620, 11-SP-1621, 11-SP-1622, 11-SP-1623 and 11-SP-1624, Office of the Brunswick County Clerk of Superior Court (collectively, the "Development Loan Foreclosures"). D. Pursuant to the Development Loan Foreclosures,First Troy SPE,LLC,a wholly owned subsidiary of First Bank,acquired all of the Subject Property other than certain individual residential lots within the Subdivision that had been released from the liens of the Development Loan Deeds of Trust in the ordinary course of business. All of the property acquired by First Troy SPE,LLC pursuant to the Development Loan Foreclosures is hereinafter collectively referred to as the"Remaining Development." E. Subsequently,by Deed of Record at Book 3334 Page 510,Brunswick County Registry, First Troy SPE,LLC conveyed all of the Remaining Development to Horton,and Horton thereby became successor in interest to the Original Declarant in all of the Remaining Development. F. Section 7 of Article I of the Declaration defines the "Declarant" as the Original Declarant, or any successor in interest to the Original Declarant in any undeveloped portion of the Subdivision or any Lots within the Subdivision"not previously disposed of"by the Original Declarant. Accordingly,upon its acquisition of all of the Remaining Development,Horton became the"Declarant" under the Declaration. G. Article V, Section 3(f)of the Declaration expressly allows the Declarant to amend the Declaration without Member approval to conform this Declaration to the requirements of any governmental agency having legal jurisdiction over the Property during the Declarant Control Period. H. The Declarant Control Period has not yet terminated. I. Horton now desires to amend the Declaration to conform the Declaration to the requirements of the State of North Carolina,Division of Water Quality. • NOW THEREFORE,the Declaration is hereby amended as follows: 1. The first sentence of the second paragraph of Article VII,Section 4 of the Declaration is deleted ih its entirety and laced with the following: 1 The maximum allowable built-upon area for Lot 6 through Lot 14,inclusive,Lot 16,Lot 18 and Lot 31 through Lot 80,inclusive,in Phase 1B/1C is 3,844 square feet per Lot.The maximum allowable built-upon area for Lots in Phase 3 Section 2C,except for Lot 3272, Lot 3275,Lot 3276,Lot 3278 through Lot 3280,inclusive,Lot 3287,Lot 3302 through Lot 3305,inclusive,Lot 3310 through Lot 3314,inclusive,Lot 3316,Lot 3317,and 3324,is 3,768 square feet per Lot.Except as stated herein,the maximum allowable built- • ' 4, 00 f Lot. 2.

May 23, 2019 NCDEQ—Wilmington Regional Office 127 Cardinal Drive Ext. Wilmington,NC 28405 Attn: Kelly Johnson RE: Hawkeswater—Request for Additional Information Dear Mrs. Johnson, On behalf of DR Horton, we are submitting a response to your comments emailed May 20th, 2019. Please find your comments listed below with our response provided in bold. 1) Modifications are proposed for four ponds: a) Phase 1/Pond 3: i) Rule: Which rule is this pond being designed under(1995, 2008 or 2017)? It was most recently designed to the 1995 rule,but the pond appears to have been redesigned under the 2008 rule. (The impervious is not increasing, and the surface area of the permanent pool is not increasing such that it does not appear that you are increasing the size of the SCM.) But, this project is using the 1.5"design storm, the 2008 Average Depth formula#2, and the 2008 percentage for forcbay volume(18-22%). (If you are opting to use the 2008 design and the associated Average Depth formula #2 then please clarify the elevation of the bottom of the shelf and ensure that the top of the sediment elevation is at 5.0ms1.) • This pond is designed using the 2008 rules,the sediment storage has been taken into account ii) It appears from the plans that the excavated depth is at 4.0ms1 with a 1 ft sediment storage elevation such that the top of the sediment is at 5.0msl. Please do not count the volume of the pond between 4.0ms1 and 5.0ms1 in the calculations because that area is intended to be preserved for sediment storage. [.1053(3) • This has been corrected and shown on the updated stage storage chart iii) The Temporary Pool is at 18.6msl. The calculations show surface areas for 18.0ms1 and 19.0ms1. Please show the surface area of the temporary pool at 18.6msl. (I interpolated the surface area of the pond(main+ forebay) to be 24,777sf.

[.1042(2)(g)(ii), .1002(15), and .1002(38)] • DA map added b) Phase 3/Pond 2: i) Elevations: The plans show that the excavated depth(the bottom of the sediment storage) is at 4.0ms1 in both the main pond and the forebay, but the calculations show that the excavated depth in the main pond is at 1.0ms1 in the main pond and at 5.0ms1 in the forebay. Please make any necessary corrections. • Calculations updated to reflect such ii) Rule: I have not checked the pond design pending verification of the depths. But, please clarify which rule the pond is intended to be designed under(I believe it is 1995?) and ensure that it is designed under a single set of regulations. • All under 1995 rules iii) Please submit a second copy of Sheet C-4.0. [.1042(2)(g), .1042(2)(h), .1042(2)(i), .1042(2)(m), and .1050(16)] • Noted c) Phase 3/Pond 4: i) 2017 Rule: The impervious area increased and so this pond should be designed under the 2017 Rule. But, it appears that this project uses the 2008 forebay percentage, 18- 22% of the whole permanent pool. Please ensure that the pond is designed to a single set of regulations. Since the pond is constructed, please provide justification if the forebay is too big. [.1053(5)(a)] • The pond was done initially under 2008 rules but now under 2017 rules, since done multiple times, sent the wrong spreadsheet depicting the 2008 rules before, submitted the 2017 rule spreadsheet along with supplement.

Is this intended to be the Temporary Pool Elevation? • 9.2 is the temporary pool which represents the next outlet elevation (2) The Temporary Pool is at 8.77ms1 per the plans' cross section. The calculations show surface areas for 8.0ms1 and 9.0ms1. Please show the surface area of the temporary pool at 8.77ms1. (I interpolated the surface area of the pond(main+ forebay) to be 25,259sf. [.1042(2)(f)] • Since 9.2 is the next highest outlet—the surface area at that elevation is 26,286 as shown on stage storage calculations. (3) The next available outlet above the permanent pool is 9.2ms1. Is that intentional or should that be 8.77ms1 on the outlet structure detail? Please make any changes the drawdown if they are needed. • The 8.84 is the theoretical temporary pool out 9.2 is the next outlet, all calculations reflect the 9.2 with the detail showing the theoretical elevation (4) The supplement shows that the Temporary Pool is at"9ms1." If a rounding correction is needed,please make that correction. • Based on the format of the spreadsheet, it did not show the tenths,this has been created and part of the package iii) Please submit a second set of plans. (Ph3/Ponds 4 and 6 are on the same set of plans.)

It shows that there are 63 lots (1-7, 130-154 & 156- 186) at 4,500sf/lot. That totals 283,500sf for the buildings/lots. However, the buildings/lots in the Attachment B shows only 269,636sf? • fhe Attach B updated, I can only go by as-built information and walking the site, the impervious numbers for Phase 1 Pond 1 and 2 were based on petinit approved on 4/30/13 by Cape Fear Engineering. I have placed the record- drawings that show the breakline for the grades and stormdrainage to these two ponds, these are the impervious numbers provided in the chart. Both building areas are less than in the permit. Based on all lots having 4500 sf per lot in the neighborhood besides the ones we have modified, I cannot see where the 4/30/13 numbers were originated but again shown less than shown for the buildings/lots. In the chart, the numbers in parenthesis are the new numbers, have added such for the future to make the total the same. For this phase, the actual building impervious is 265,000 sf which is below the 269,636 sf, therefore the ponds are sized for the impervious that are draining toward it. ii) Phase 3/Pond 5: Please double check the data for Ph3/Pond 5 (which isn't being modified in this modification). It shows that there are 36 lots (3231-3272) at 4,500sf/lot. However,this appears to be 42 lots. Attachment B shows that there is 162,000sf of buildings/lots for this pond but if there are 42 lots at 4,500sf/lot would be 189,000sf? • Mistake on lot numbering on last submittal, the same number of lots which is 36 drain to pond, Lots 3256-3260 not part of this pond drainage area MN n -Z m I D D A - < m- f - r - z m o z Z n N m A 0 w I •• 'N 0 " J %0 U 0 J 'i D X " "113 0 ] N U .1 0% 0 PARA MOUNTE ENGINEER I N G, I N C. iii) Phase 3/Ponds 4 and 6 (Treating Phase 3A Section 2B): The table shows the following lots per pond. There appears to be a typo as shown in italics. This range of lot numbers would encompass most of the others in this phase. Ph3/Pond 4 Ph3/Pond 6 3273-3283 3284-3301 3303-3317 3227-3318 3328-3332 • The lot numbers have been updated to reflect all draining to such. A few lots on the drainage area boundary have been split as the grading suggest. The calculations have not changed just verified lot numbers for attachment B iv) Other Ponds: I have not checked all of the ponds' data. I just happened to notice that these values didn't add up. Please double check all of the numbers so that no other issues come up. This modification will cover the changes summarized in Item 1 above. If the data inconsistencies for Ph3/Pond 1, Ph3/Pond 5 or any other ponds are not typos, then they will need to be addressed in a future permit modification. • All double checked v) Rule Subject: This line will be updated for the appropriate ponds based on the response to this letter. • All reflect rule being used vi) Attachment C: I have split the BUA/lot information out into a separate attachment, Attachment C, in order to simplify Attachment B. • Noted 3) Plans in Full Set: a) When we met on March 21 st, we went through the currently-permitted plan sheets to determine which ones would continue to be permitted after the pending approval and which ones were intended to be replaced. In addition to the plans for the four ponds currently in review, the following is a list of plan sheets that were to continue to be kept in the permitted plan set: i) Approved 4/30/13: Cover, SW-1, SW-2, SW-3, SW-5 (Keep the area circled in red.), P-1 (Keep Phl/Pondl and Phl/Pond 2. Replace Phl/Pond 3.), P-2 (Keep Ph3/Pondl. Replace the rest.), P-3 (Ph3/Pond7. Replace the rest.), and D-1. (Note, SW-4 is to be replaced by pending Ph3/Pond 2's design.)

All lots are depicted in the plan sets from above. (2) All of the lots on the plan have the same lot number as appears in the deed restrictions. • Per the deed restrictions, all lots minus the ones shown in section 1 are for 4500 sf per lot, the specific numbers and BUA per lot on the ones less are written in the recorded deed restrictions (3) All of the phases/sub phases are shown on the plans so that Lot 1 in Phase 1 can be differentiated from Lot 1 in Phase 3. • Besides the areas that DR Horton has developed, in which lots numbers are consistent with the phase included, all other lot numbers are in the 3/21 package, I have provided the record drawings for Phase lA(pre) DR Horton that shows lot numbers, these areas were permitted with the lots provided in the earlier submittals. We verified to place in Attachment B. We are also updating the ponds to make them match the parameters of the 4/30/13 approved permit For instance, 10222 Hawkeswater Blvd should be an additional lot next to Lot 5 below,but it is not on the plans. I do not see a more recent plan sheet for this area. The deed restrictions also do not list Lots 4 or 5 for Phase 3 Pond 1. It is unclear if these lots were renumbered or if they were not included in the deed restrictions. There may be other examples.

I believe have answered the questions,the only area of concern is the Phase 3 Pond 1, have enclosed the drainage area that was in the 2013 approved permit to show lots to drain to pond including Lot 6 and the permit to show the chart as it was permitted by previous design team and developer. Again please take a peek at these but plan to drop off end of day Tuesday, I have all ready to print but want to again just be on the same page on things Thanks Tim For your comments below. 1.) Phase 3/Pond 3—this is the area adjacent to Phase 3 Pond 2 that pond taken out and berm placed, no impervious and no pond. Are you saying that Phase 3/Pond 3 is not going to be a pond in the permit anymore? What happened to its drainage area? If there were lots that drained to it,then where do they drain now? a. Response—Phase 3 Pond 3, I have clouded the area where that pond was to be located, it is now a berm b. I think you are saying that this area is now a berm and that you have drawn the cloud on an old set of plans which has been replaced by a new set that doesn't have these lots, but rather a berm. I am really only concerned about the most recent design? If there is a berm,then that is fine. If you are saying that you have removed some lots,then please remove them from the spreadsheet and show that all the numbers balance. 1 POND 2 DRAINAGE AREA / ..- me : : `a r,' ,•-- r, 309 AC(PHASE 3 ONLY) 1 r 1 �� •,i' ifir�r , `.xTri r'�Y�rr; 1 :POND 3 - ' 36 ,,,�ti 0„e, ,i I `.4 . ;DRAINAGE �i i% t1 :AREA 1 It�� 1't o )`ti L�yI i PROD {BOUN Y __-' r. —' ii1,' ' "ivit , , ...W\ , , m-k,%; 2.) Phase 3/Pond 1/Pond 2—Comment 2b) used utility as-builts that show catch basins and grade breaks to show how lots drain to each pond. This section is not designed by us or built by Horton. As stated in the response letter, I do not know how they got the impervious for the buildings, but each pond actually has less impervious than permit provides. All lots except ones in the 4th revision of the deed restrictions are recorded for 4500 sf. The ponds are built to the design except for the minor maintenance items that we are taken care now. These two ponds with the current BUA were permitted twice and constructed in that manner. Comment 2b had six parts and I am not sure which one you are referring to, but they are generally about potential data typos. I am just trying to get the attached spreadsheet to balance. We have to figure out where the numbers came from. If the numbers don't add up or if we can't figure out where they came from,then that is the issue to address. For instance(comment 2bi)if the pond design data shows 269,636sf of"buildings" but there is actually 283,500sf then that is an issue because we don't know that the pond can hold the water. a. Response—in the 5/24 chart, using the language above,the impervious area for both Pond 1 and Pond 2 in Phase 1 have less impervious for buildings than what is approved,the area in parenthesis represent such. Therefore the ponds are constructed to handle the drainage from the permitted BUA b. I am not sure I follow this. 283,500>269,636? Please ensure that the spreadsheet balances so that you can demonstrate that each pond is actually less impervious than the permit provides. 3.) Comment 3b)All plans in the ones to keep should reflect the correct lot numbers,for the deed restrictions, again all lots except ones stated specifically are 4500 sf, so no issue with lot numbers. a. I didn't look at every single lot, but I did look at 10222 Hawkeswater Blvd because the neighbors have called about it. It should be on an additional lot next to Lot 5 below, but it is not on the plans. I do not see a more recent plan sheet for this area (after going through the ones that we decided were the latest ones at our most recent meeting). This is one example of a lot that doesn't appear to be on the plans. �t \ . �,i yyyppp .111. a +1 71 .� ��I �j . `mays � . '' F.7 '‘. .--a ' 0 , . ... _. . 4, V; '.-.G.' " . I .. 1 f r 1 II Er— --,-7—,--. - ' -- -',.. .-..., -‘'. - N 0 r• Response—I have also clouded this area,this is the drainage area map straight out of the permit package,we scanned such back in 2011 when working on the townhome section. Also the chart —Attachment B includes Lot 6. The drainage area provided mimics the one in the original permit 2 approval and modification of 4/30/13. I will have to look at this when it comes in. The sheet number and date were cut off of the pdf in the email. I have summarized the sheet numbers and the associated permit dates that will make up the final set after this modification in Attachment D row 17 based on our last meeting. I will add the list of sheets permitted in the upcoming approval in the table once that list is finalized. Please review this list for accuracy. If you would like to schedule a file review, please let me know. b. Also,the deed restrictions(B2745/P0986)do not list Lots 4 or 5 for Phase 3 Pond 1. I believe that this is the latest version of the restrictions I see for that section. (I have several versions of deed restrictions on file, but none of them have the various maps attached that are referenced in them.) It is unclear if the lots were renumbered, if the lots were not included in the deed restrictions,or if there is a more recent version of the deed restrictions that addresses the issue. i. Response,the clouded area in the deed restrictions states that this sentence is deleted and replaced with language on page 2. The listed for less than 4500 sf per lot are the ones we have provided for Phase 1B/1C,the lots 4-5 in Phase 3 Pond 1 are separate and part of all other lots remain at 4500 sf/lot. The Phase 3 Pond 1 was not permitted by Paramounte and not constructed by Horton. We both built the lots shown on Hawkeswater Blvd but mimics the permit drainage area line and number of lots. Also upon as-built of pond,the surface area is constructed per the designed amount ii. As we have discussed, DR Horton is responsible for the entire permit, regardless of who built the earlier areas. I will look at this when it comes back in. I hope you are saying that all of the lots are appropriately deed restricted? You have clouded the following statement recorded 2/13/19. It replaces the first sentence in the second paragraph of an earlier document, but I am not sure what that document is or what section(s) it would cover. Please see the attached Excel file,attachment C,column E and ensure that the book/page for each lot in the entire subdivision is recorded and summarized in the spreadsheet table which will become a permit attachment. If the spreadsheet if fully filled out,the numbers balance,and it matches the permitted configuration on the plans in the list in Attachment D then everything should work out. If that is not the case,then please get the spreadsheet to balance and find the deed restriction book/pages for each lot before resubmittal. 1. The first sentence of the second paragraph of Article Vll,Section 4 of the Declaration is deleted ih its entirety and replaced with the following: The maximum allowable built-upon area for Lot 6 through Lot 14,inclusive,Lot 16,Lot 18 and Lot 31 through Lot 80,inclusive,in Phase 1B/1C is 3,844 square feet per Lot.The maximum allowable built-upon area for Lots in Phase 3 Section 2C,except for Lot 3272, Lot 3275,Lot 3276,Lot 3278 through Lot 3280,inclusive,Lot 3287,Lot 3302 through Lot 3305,inclusive,Lot 3310 through Lot 3314,inclusive, Lot 3316,Lot 3317,and Lot 3324,is 3,768 square feet per Lot.Except as stated herein,the maximum allowable built- upon area for all remaining Lots is 4,500 square feet per Lot. 2. Except as amended herein, all terms and provisions of the Declaration remain unmodified. As amended herein,the Declaration remains in full force and effect.

Horton, Inc. Attn: Mr. Michael C. Loiacono, Vice President 1121 Military Cutoff Road, Suite C-322 Wilmington,NC 28405 Subject: Request for Additional Information Stormwater Project No. SW8 130412 Hawkeswater Brunswick County Dear Mr. Loiacono: The Wilmington Regional Office received and accepted a modified State Stormwater Management Permit Application for the subject project on March 21, 2019. A preliminary in-depth review of that information has determined that the application is not complete and that additional information is needed. To continue the review,please provide the following additional information: 1) Modifications are proposed for four ponds: a) Phase 1/Pond 3: i) Rule: Which rule is this pond being designed under(1995,2008 or 2017)? It was most recently designed to the 1995 rule,but the pond appears to have been redesigned under the 2008 rule. (The impervious is not increasing, and the surface area of the permanent pool is not increasing such that it does not appear that you are increasing the size of the SCM.) But, this project is using the 1.5"design storm,the 2008 Average Depth formula#2,and the 2008 percentage for forebay volume(18-22%). (If you are opting to use the 2008 design and the associated Average Depth formula#2 then please clarify the elevation of the bottom of the shelf and ensure that the top of the sediment elevation is at 5.0ms1.) ii) It appears from the plans that the excavated depth is at 4.0msl with a 1 ft sediment storage elevation such that the top of the sediment is at 5.0msl. Please do not count the volume of the pond between 4.0msl and 5.0ms1 in the calculations because that area is intended to be preserved for sediment storage. [.1053(3)] iii) The Temporary Pool is at 18.6ms1. The calculations show surface areas for 18.0ms1 and 19.0msl. Please show the surface area of the temporary pool at 18.6ms1. (I interpolated the surface area of the pond (main+forebay)to be 24,777sf. [.1042(2)(f)] iv) Please submit a second set of plans. [.1042(2)(g), .1042(2)(h), .1042(2)(i), .1042(2)(m), and .1050(16)] v) Please show the drainage area on the plans. [.1042(2)(g)(ii), .1002(15), and .1002(38)] b) Phase 3/Pond 2: i) Elevations: The plans show that the excavated depth(the bottom of the sediment storage) is at 4.0ms1 in both the main pond and the forebay, but the calculations show that the excavated depth in the main pond is at 1.0ms1 in the main pond and at 5.0ms1 in the forebay. Please make any necessary corrections. ii) Rule: I have not checked the pond design pending verification of the depths. But,please clarify which rule the pond is intended to be designed under(I believe it is 1995?)and ensure that it is designed under a single set of regulations.

Rut, it appears that this project uses the 2008 forebay percentage, 18-22% of the whole permanent pool. Please ensure that the pond is designed to a single set of regulations. Since the pond is constructed,please provide justification if the forebay is too big. I.1053(5)(a)I ii) Temporary Pool: (1) The calculations show that the"elevation of the 1.5"water surface stage" is 8.85ft. Is this intended to be the Temporary Pool Elevation? (2) The"Temporary Pool is at 8.77ms1 per the plans' cross section. The calculations show surface areas for 8.0msl and 9.0msl. Please show the surface area of the temporary pool at 8.77ms1. (I interpolated the surface area of the pond (main - forebay)to be 25,259sf. I.1042(2)(0] (3) The next available outlet above the permanent pool is 9.2ms1. Is that intentional or should that be 8.77ms1 on the outlet structure detail? Please make any changes the drawdown if they are needed. (4) The supplement shows that the Temporary Pool is at"9ms1." If a rounding correction is needed, please make that correction. iii) Please submit a second set of plans. (Ph3/Ponds 4 and 6 are on the same set of plans.) [.1042(2)(g), .1042(2)(h), .1042(2)(i), .1042(2)(m), and .1050(16)] d) Phase 3/Pond 6: i) 2017 Rule: The impervious area increased and so this pond should be designed under the 2017 Rule. But, it appears that this project uses the 2008 forebay percentage, 18-22% of the whole permanent pool. Please ensure that the pond is designed to a single set of regulations. Since the pond is constructed, please provide justification if the forebay is too big. [.1053(5)(a)] ii) Temporary Pool: (1) The calculations show that the"elevation of the 1.5"water surface stage"is 7.15ft. Is this intended to be the Temporary Pool Elevation? (2) The Temporary Pool is at 7.16msl. The calculations show surface areas for 7.0ms1 and 8.0ms1. Please show the surface area of the temporary pool at 7.16msl. (I interpolated the surface area of the pond(main+ forebay)to be 17,060sf. [.1042(2)(f)] (3) The next available outlet above the permanent pool is 7.5msl. Is that intentional or should that be either 7.15 or 7.16ms1 on the outlet structure detail? Please make any changes the drawdown if they are needed. iii) Please submit a second set of plans. (Ph3/Ponds 4 and 6 are on the same set of plans.) (Ph3/Ponds 4 and 6 are on the same set of plans.)

It shows that there are 63 lots(1-7, 130-154 & 156-186) at 4,500sf/lot. That totals 283,500sf for the buildings/lots. However,the buildings/lots in the Attachment B shows only 269,636sf? ii) Phase 3/Pond 5: Please double check the data for Ph3/Pond 5 (which isn't being modified in this modification). It shows that there are 36 lots(3231-3272)at 4,500sf/lot. However,this appears to be 42 lots. Attachment B shows that there is 162,000sf of buildings/lots for this pond but if there are 42 lots at 4,500sf/lot would be 189,000sf? iii) Phase 3/Ponds 4 and 6(Treating Phase 3A Section 2B): The table shows the following lots per pond. There appears to be a typo as shown in italics. This range of lot numbers would encompass most of the others in this phase. Ph3/Pond 4 Ph3/Pond 6 3273-3283 i 3284-3301 3303-3317 13227-3318 3328-3332 • iv) Other Ponds: I have not checked all of the ponds' data. I just happened to notice that these values didn't add up. Please double check all of the numbers so that no other issues come up. This modification will cover the changes summarized in Item 1 above. If the data inconsistencies for Ph3/Pond 1, Ph3/Pond 5 or any other ponds are not typos,then they will need to be addressed in a future permit modification. v) Rule Subject: This line will be updated for the appropriate ponds based on the response to this letter. vi) Attachment C: I have split the BUA/lot information out into a separate attachment, Attachment C, in order to simplify Attachment B. 3) Plans in Full Set: a) When we rnei on March 21st, we went through the currently-permitted plan sheets to determine which ones would continue to be permitted after the pending approval and which ones were intended to be replaced. In addition to the plans for the four ponds currently in review,the following is a list of plan sheets that were to continue to be kept in the permitted plan set: i) Approved 4/30/13: Cover, SW-1, SW-2, SW-3, SW-5 (Keep the area circled in red.), P-1 (Keep Phl/Pondl and Phl/Pond 2. Replace Phl/Pond 3.),P-2 (Keep Ph3/Pondl. Replace the rest.), P-3 (Ph3/Pond7. Replace the rest.),and D-1. (Note, SW-4 is to be replaced by pending Ph3/Pond 2's design.) ii) Approved 10/16/18: Cover, C-1.0, C-2.0, C-4.0, C-4.1, C-6.0, C-7.0, C-8.0, and C-9.0 State Stormwatcr Permit No. SW8 130412 , Page 4 of 5 b) Phases. I ots. and 1 of Numbers: i) Please ensure that (1) All ol'the lots in the subdivision arc on the plan. (2) All of the lots on the plan have the same lot number as appears in the deed restrictions. (3) All of the phases'sub phases are shown on the plans so that Lot 1 in Phase l can be differentiated from Lot 1 in Phase 3. For instance. 10222 I Iawkeswater Blvd should he an additional lot next to Lot 5 below, but it is not on the plans. I do not see a more recent plan sheet for this area. The deed restrictions also do not list Lots 4 or 5 for Phase 3 Pond 1. It is unclear if these lots were renumbered or if they were not included in the deed restrictions.

Before I send updated sheets,just want to do a quick review of the items that will be withstanding. All items are non-calculation (or plan related) but want to verify all on the same page before sending all back in 1.) Phase 3/Pond 3—this is the area adjacent to Phase 3 Pond 2 that pond taken out and berm placed, no impervious and no pond. Are you saying that Phase 3/Pond 3 is not going to be a pond in the permit anymore? What happened to its drainage area? If there were lots that drained to it,then where do they drain now? 2.) Phase 3/Pond 1/Pond 2—Comment 2b) used utility as-builts that show catch basins and grade breaks to show how lots drain to each pond. This section is not designed by us or built by Horton. As stated in the response letter, I do not know how they got the impervious for the buildings, but each pond actually has less impervious than permit provides. All lots except ones in the 4th revision of the deed restrictions are recorded for 4500 sf. The ponds are built to the design except for the minor maintenance items that we are taken care now. These two ponds with the current BUA were permitted twice and constructed in that manner. Comment 2b had six parts and I am not sure which one you are referring to, but they are generally about potential data typos. I am just trying to get the attached spreadsheet to balance. We have to figure out where the numbers came from. If the numbers don't add up or if we can't figure out where they came from,then that is the issue to address. For instance(comment 2bi) if the pond design data shows 269,636sf of"buildings" but there is actually 283,500sf then that is an issue because we don't know that the pond can hold the water. 3.) Comment 3b)All plans in the ones to keep should reflect the correct lot numbers,for the deed restrictions, again all lots except ones stated specifically are 4500 sf,so no issue with lot numbers. a. I didn't look at every single lot, but I did look at 10222 Hawkeswater Blvd because the neighbors have called about it. It should be on an additional lot next to Lot 5 below, but it is not on the plans. I do not see a more recent plan sheet for this area(after going through the ones that we decided were the latest ones at our most recent meeting). This is one example of a lot that doesn't appear to be on the plans. r 3 _ imp...,,, —w""ir l''',:ir V,-,A*4.• „' ik ..00. .2'.."' 4::, 'lee":' ',N,•, 4i.\ \ 1' , ..., .1111.m.,11:4 IMP, 3, ,.... ,„ .\.\,„ ,,, , \,1/4..‘, , , .....„ . ,„__ .. ,,,,, 'k. \., • 0 4 ' 4,0* -— : • " --",/Az,..N: \\ i f mr ••• . t. 4 _;t.1 A z., ...'"P 40-' Ilk';:lii-t. ------- -- 4 w .9* •••• _a. 744. 1... .a.S.ipc1;:�. ., j i s .r r � t . _r i' l ti � w �. . (3).,, 4:1,, -.....-- ,_ , ,\,_ w),.. 4 b. Also,the deed restrictions(B2745/P0986)do not list Lots 4 or 5 for Phase 3 Pond 1. I believe that this is the latest version of the restrictions I see for that section. (I have several versions of deed restrictions on file, but none of them have the various maps attached that are referenced in them.) It is unclear if the lots were renumbered, if the lots were not included in the deed restrictions,or if there is a more recent version of the deed restrictions that addresses the issue. 4.) Comment 4)As before,all lot numbers are consistent with lots in plans and deed restrictions. Again sending such, because these are the only items!see that are confusing because of time and different owners/consultants in the project.On the chart,the blue is what has been updated on this submittal, making the whole column does not mean all updated, but easier to give you a heads up.

Horton states and declares as follows: A. Hawkeswater I, Development, Inc., a North Carolina corporation, Hawkeswater II Development,Inc.,a North Carolina corporation,Hawkeswater III Development,Inc.,a North Carolina corporation,and Riverside Land Holdings,LLC,a North Carolina limited liability company(collectively, the "Original Declarant") previously made that certain Declaration of Covenants Conditions and Restrictions for Hawkeswater at the River Subdivision recorded in Book 2745 Page 986, Brunswick County Register of Deeds,as modified by:(i)that First Amendment to the Declaration of Hawkeswater at the River Subdivision of record at Book 3380 Peg 1230,Brunswick County Register of Deeds;(ii)that Annexation Declaration for Hawkeswater at the River Subdivision of record at Book 3493 Page 659, Brunswick County Register of Deeds(the"Annexation Declaration");(iii)that Second Amendment to the Declaration of Hawkeswater at the River Subdivision of record at Book 3550 Page 465, Brunswick County Register of Deeds; and(iii)that Third Amendment to the Declaration of Hawkeswater at the River Subdivision of record at Book 4113 Page 749,Brunswick k County Register of Deeds(collectively, as amended and restated,the"Declaration"). B. All of the real property currently subject to the Declaration(the"Subject Property")was originally owned and held by the Original Declarant for the purpose of developing it into Hawkeswater at the River Subdivision(the"Subdivision"). C. All of the Subject Property was conveyed by the Original Declarant to trustees for the benefit of Cooperative Bank,a North Carolina bank,by Deeds of Trust of record at Book 2579 Page 889, Book 2605 Page 1340,Book 2606 Page 37,Book 2606 Page 72 and Book 2606 Page 106,Brunswick • County Registry(collectively,the"Development Loan Deeds of Trust"),as collateral for a loan or loans, the proceeds of which were to be used in the development of the Subdivision (collectively, the "Development Loan"). Subsequently,all of the assets of Cooperative Bank,including the Development Loan and the Development Loan Deeds of Trust,were acquired by First Bank,a North Carolina Bank. 7ECEIVEr MAR 2 1 2019 a 4" NeR1 J1iILiiiI1Lsulok IZ! o2 f � ' Subsequent to that acquisition,foreclosure proceedings were instituted under all of the Development Loan Deeds of Trust,which proceedings are of record at 11-SP-1620, 11-SP-1621, 11-SP-1622, 11-SP-1623 and 11-SP-1624, Office of the Brunswick County Clerk of Superior Court (collectively, the "Development Loan Foreclosures"). D. Pursuant to the Development Loan Foreclosures,First Troy SPE,LLC,a wholly owned subsidiary of First Bank,acquired all of the Subject Property other than certain individual residential lots within the Subdivision that bad been released from the liens of the Development Loan Deeds of Trust in the ordinary course of business. All of the property acquired by First Troy SPE,LLC pursuant to the Development Loan Foreclosures is hereinafter collectively referred to as the"Remaining Development." E. Subsequently,by Deed of Record at Book 3334 Page 510,Brunswick County Registry, First Troy SPE,LLC conveyed all of the Remaining Development to Horton,and Horton thereby became successor in interest to the Original Declarant in all of the Remaining Development. F.

Horton,Inc. Attn: Mr. Michael C. Loiacono,Vice President 1121 Military Cutoff Road, Suite C-322 Wilmington,NC 28405 Subject: NOTICE OF VIOLATION,NOV-2019-PC-0192 Hawkswater Stormwater Permit No. SW8 130412 Brunswick County Dear Mr. Loiacono: On March 14,2019,Wilmington Regional Office staff of the Division of Energy,Mineral and Land Resources(DEMLR)performed a file review compliance inspection of the subject project, located on Village Road,Leland, in Brunswick County,North Carolina. A summary of events to date is included below. By copy of this letter to the Brunswick County Building Inspector,this office is requesting that the Building Inspector consider withholding building permits and-Certificates of Occupancy for this project until this matter is satisfactorily resolved. If this is not sufficiently resolved by April 15,2019 DEMLR will begin the recommendation for the enforcement of a civil penalty. History: 1. 4/30/13: The original permit was written as SW8 060354 to Riverside Land Holding II,LLC, who later lost the project to the bank. The first SW8 130412 permit was issued to D.R. Horton, Inc. in April of 2013 after becoming the new property owner. Section II(16) (f)required that, "The maximum built upon area per lot is 4,500 square feet for Phase I. Phases 2 and 3 shall be specified with a future stormwater permit modification..." D.R. Horton,Inc. is therefore responsible for maintaining the impervious area per lot for all lots, including lots covered by the permit that were constructed by the previous permittee. DR Horton,Inc. is also responsible for all other permitting responsibilities for this project in its entirety. 2. 8/24/17: A Notice of Non-Compliant Inspection was issued.A permit modification application had been accepted on June 15,2017 to modify Phase 3 Ponds 5 and 6. During the review, DEMLR found that the project's plans did not match the configuration on Google Earth, and so a site inspection was conducted on August 24, 2017. There were ponds not built per the plan such as Phase 3 Pond 5 which was permitted to be constructed outside of the loop formed by Keekle Lane but was instead constructed inside the loop formed by Keekle Lane. Unpermitted construction such as several townhomes was also identified. Homes had been built that were not on the plans such as 10222 Hawkeswater Blvd. Restrictions had been recorded in B2745/P0986, but the restrictions did not appear to cover all of the lots in the permitted configuration because the impervious area for Phases 2 and 3 was not permitted in 2013. It also appeared that the impacted ponds may not have been designed to accommodate full build-out from those lots. O&M Agreements were needed for ponds that had been modified or needed to be modified. Certifications were needed for ponds that had finished construction. There were also specific technical changes needed for specific ponds, and maintenance was needed.

The modification was issued for Phase 3 Pond.4 and Phase 3 Pond 6 to be redesigned, and to add deed restrictions for Phase 3A Section C. b. The Plan of Action requested on August 24,2017 was due on September 25,2017, but it was not received. 4. 11/17/17: An incomplete permit modification application package was received. DEMLR sent three emails requesting specific technical information that were not addressed. For instance,no application was submitted with the modification package. It was unclear which ponds were proposed for modification. Some drainage areas were shifting per the package. However,no revised pond calculations were submitted. The narrative also discussed the deed restrictions for the lots that the permittee was"responsible for". In further discussion,DEMLR explained that D.R.Horton, Inc. is responsible for all of the lots inside the project area, including the lots involved in the foreclosure. 5. 12/14/17,Notice of Deficiency: The letter referenced all prior correspondence summarizing the deficiencies previously identified. 6. 2/15/18,Permit Modification Application was accepted: Even though DEMLR knew the application was not complete, it was accepted in hopes that DEMLR could work with the permittee to clarify the items that needed to be addressed. A Request for Additional Information was mailed on April 25,2018 detailing the specific items needed to complete the review. Many emails followed,but the requested items were still not submitted. The data submitted was conflicting and incomplete. Specific examples include the fact that the package did not specify which of the ten ponds were being modified. For instance, if there were three ponds to be modified then there should be three sets of calculations. There should also be three supplements, O&M agreements,plans and other supporting documents for the same three ponds shown in the calculations. This was not the case. Supplements and calculations were submitted for some ponds,but pages were missing and different ponds were listed in the supplements and/or calculations and plans. Deed restrictions were also not submitted for all of the lots in the subdivision that were changing. Additionally, certifications for the ponds that were built-out were not all submitted. Various versions of forms were submitted on 11/17/17, 1/23/18, and 2/2/18,but it was unclear which forms/plans/calculations/deed restrictions/other supporting documents were the latest versions for the intended application and which versions you intended DEMLR to remove from your application package. Also,we had discussed specific lots that needed to be added to the plan such as those near 489 Esthwaite Drive SE which were not addressed in the package. Additionally,plans were labeled as"Phase 2"but it was not clear where Phase 2 was located or which pond(s)were intended to treat it because no drainage area map was submitted. 7. 8/9/18,Meeting: A meeting was held between Andy Mills(DR Horton), Tim Clinkscales (engineer for DR Horton),and Kelly Johnson(DEMLR)to determine what items were needed to continue the review. We determined that the pending modification(later issued on 10/16/18) would address a portion of the items needed and that a subsequent modification application would be submitted to address the remaining items. The pending modification would modify Phase 3 Pond 5 and add the configuration for Phase 2(which was determined to be the townhomes)to the permit. We agreed that the future permit application would modify three ponds(Ph3/Pond 4, Ph3/Pond 6,and Phl/Pond 3). Revised deed restrictions would also be needed for the development. 8. 10/16/18, A permit modification issued with Notice of Continuing Deficiency because an additional modification was needed per the August 2018 meeting. The Plan of Action was due on November 19,2018. Permit Section II(16)(f)(ii)required an upcoming modification by November 19,2019. f State Stormwater Permit No. SW8 130412 Page 3 of 5 • 9. 12/12/18,Application Return: An incomplete application was received on December 12,2018 and it was returned. The application contained a considerable amount of conflicting data similar to previous applications,and did not fully address the items discussed at the August 2018 meeting. Examples of the conflicting and incomplete data include discrepancies between deed restriction BUA/lot values and numbers of lots versus the summary tables submitted. Pond revision data was included in the package that was not addressed at the prior meeting. But,the package did not specify that other ponds would be modified in addition to the three identified at the August 2018 meeting. DEMLR requested that you all determine which ponds needed modifications, and then submit modification documents for those ponds. 10. 1/29/19,Project.Return: A minor modification application was accepted on January 28, 2019 following a completeness review. However, once it was forwarded to the review engineer, it was determined that,again,the application submitted did not fully address the items previously discussed. A major modification was needed per 15A NCAC 02H .1002(23)to increase impervious area for at least one of the ponds,Ph3/Pond 4. The minor modification application was therefore returned. It was again unclear which ponds you intended to modify because of the significant amount of conflicting,missing, and incomplete data in the package. The three ponds previously discussed,Ph3/Pond 4,Ph3/Pond 6,and Phl/Pond 3,were included but an additional pond,Ph3/Pond 2 was also discussed in the package. 11. 3/14/19,Notice of Violation: DEMLR has spent countless hours attempting to communicate what is needed,and has made every effort to work with you to ensure that you understand the requirements. As documented in this letter,at the August 2018 meeting, and in the numerous emails and letters on file you have submitted six incomplete modification applications. Specifically, submissions on 11/17/17, 1/23/18 and 2/2/18 were revised a fourth time on 2/15/18 and accepted before the package was returned. Then,two more applications on 12/12/18 and 1/28/19 were eventually returned. Meanwhile,the project has been out of compliance for over a year and a half. This is not acceptable. Notice of Violation: The project has been found in violation of Stormwater Permit Number SW8 130412, issued pursuant to the requirements of the stormwater rules, 15A NCAC 2H.1000.The violations found are: 1. Failure to construct according to the approved plan. Per Section II(15)of the Permit the permittee shall construct, operate and maintain the approved stormwater system in accordance with the permit requirements and the supporting documents.In addition,per Section II(6),the permittee shall submit to the Director and shall have received approval for revised plans, specifications, and calculations prior to construction,for any modification to the approved plans. There are several ponds that are not constructed per the plan. Additionally,Permit Section II(16) (f)(ii)required a modification to the October 2018 permit to be submitted by November 19, 2018. All parties had agreed to this process as documented in the August 2018 meeting minutes,but a complete application has not been submitted as of this date. 2. Failure to certify the stormwater system. Per Section II(10)of the Permit,upon completion of construction, prior to issuance of a Certificate of Occupancy, and prior to operation of this permitted facility,a certification must be received from an appropriate designer for the system installed certifying that the permitted facility has been installed in accordance with this permit, the approved plans and specifications, and other supporting documentation. Any deviations from the approved plans and specifications must be noted on the Certification.An administrative review of the file revealed that this Office has not received the Designer's Certification for all ponds. Two partial certifications are on file; Ph3/Pond 5 (partial),Ph2/Pond 3 (partial). However, full certifications for all completed ponds is required. 3. Failure to provide recorded deed restrictions. Per Section II(16)of the Permit,a copy of the recorded deed restrictions was required to be submitted within 30 days. Revised deed restrictions are needed. Specifically,recorded deed restrictions are needed for all sections where lots have been sold. The deed restrictions form is needed where lots are permitted or are proposed to be permitted but are not yet not sold. State Stormwater Permit No. SW8 130412 Page 4 of 5 4. Failure to Operate and Maintain the Stormwater System. Per Section II(15)of the permit,the Permittee shall provide the operation and maintenance necessary to assure the permitted stormwater system functions at optimum efficiency. As discussed in the August 24,2017 inspection,ongoing maintenance is required. Operation and Maintenance agreements are also required for all ponds. These need to be updated for ponds that need modifications. At least three ponds are currently operating in an unpermitted configuration and therefore without an approved O&M for the pond's design;Ph3/Pond 4, Ph3/Pond 6,and Phl/Pond 3. A fourth pond, Ph3/Pond 2,may also be included in this list. A complete list is pending the upcoming modification. As also stated in the permit,the approved Operation and Maintenance Plan must be followed in its entirety and maintenance must occur at the scheduled intervals, including,but not limited to: • Routine monthly inspections; • Sediment Removal; • Mowing and re-vegetation of side slopes; • Immediate repair of eroded areas; • Maintenance of side slopes in accordance with the approved plans and specifications; • Debris removal and unclogging of the outlet structure,orifice device and catch basins and piping; • Access to the outlet/bypass structure must be available at all times. To correct these violations,you must: 1. Modification: a. As discussed over the enclosed emails for the January 2019 return,please determine which ponds need to be modified,and submit an application to modify those ponds. I believe that Ph3/Pond 4,Ph3/Pond 6, and Ph1/Pond 3 need to be modified. But, as previously discussed you also submitted data for an additional pond(Ph3/Pond 2)in relation to the January 2019 return.It is therefore unclear how many or which ponds need to be modified. Please have your engineer compare the permitted data to the proposed and/or constructed data and submit an organized and complete modification package for all ponds that need to be modified. If any pond increases its impervious area or increases the overall size of the stormwater control,then a major modification is needed per 15A NCAC 02H .1002(23). As of January 2019,this was the case for at least one pond,Ph3/Pond 4. b. If lots were sold without deed restrictions,please ensure that the respective pond(s) account for that impervious area at full build-out per 15A NCAC 02H.1002(23). c. Update Attachment B of the permit per Permit Section II(16)(f)(ii). d. Ensure all homes planned and/or constructed are on the plan such as 10222 Hawkeswater Blvd and the homes near 489 Esthwaite Drive SE which were not previously accounted for. e. Please ensure all data is clear and consistent. If you modify three ponds,please clarify which ponds they are, submit all supporting documents labeled as referring to those ponds. If you submit revised deed restrictions,please ensure that it is labeled in a way that can be lined up per phase and per pond. 2. Deed Restrictions: a. Submit recorded deed restrictions for all sections where lots have been sold. h. Submit the notarized deed restrictions form for sections where lots are permitted or are proposed to be permitted but not sold. 3. O&M: a. Submit an O&M for any pond that is redesigned from its permitted condition. b. Maintenance was discussed in August of 2017,which is likely out of date. Please ensure that all systems are maintained appropriately per their O&M Agreement. State Stormwater Permit No. SW8 130412 Page 5 of 5 Please provide a"Plan of Action"by April 15,2019 to DEMLR that states how and when these violations will be corrected.If we do not receive your plan of action by this date you will be in violation of 15A NCAC 2H.1000,which will result in the recommendation of the initiation of enforcement action such as the assessment of civil penalties,pursuant to NCGS 143-215.6A.

On the deed restrictions per pond, I can do such, but these are exactly the same way provided in the October approval submittal so mimicked such. In the meeting notes from August in this email chain below, we discussed that the pending mod at that time(which was issued in October 2018)would only modify Phi/Pond 5, and that at least three other ponds would need to be modified in the future (in the currently-pending modification). You all needed more time to get the calculations etc together for the other ponds. The 165,092sf value in Attachment B from October was not permitted. It was a placeholder to capture the data we knew was coming because we had gone through so much to figure it out. The permit text specified that the modification to update the data in Attachment B was due on 11/19/18.

I am also enclosing the pdf of Attachment B, I am not sure what else I need to provide on this chart. On the deed restrictions per pond, I can do such, but these are exactly the same way provided in the October approval submittal so mimicked such. In the meeting notes from August in this email chain below, we discussed that the pending mod at that time(which was issued in October 2018)would only modify Ph3/Pond 5, and that at least three other ponds would need to be modified in the future (in the currently-pending modification). You all needed more time to get the calculations etc together for the other ponds. The 165,092sf value in Attachment B from October was not permitted. It was a placeholder to capture the data we knew was coming because we had gone through so much to figure it out. The permit text specified that the modification to update the data in Attachment B was due on 11/19/18. Attachment B did not have an approval date for the 165,092sf because it was pending, and Attachment C specified that only Ph3/Pond 5 was modified in the October 2018 permit. I.DESIGN STANDARDS 1. This permit is effective only with respect to the nature and volume of stormwater described in the application and other supporting data. 2. This storrwater system has been approved for the management of stormwater runoff as described in Attachment B.This project is not In compliance. There are lots that do not have deed restrictions established for them in this permit. A Modification application to uodate the data In Attachment 8 is due on November 19.2018. 3. The runoff from all built-upon area within the permitted drainage areas of this project must be directed Into the permitted stormwater control system. 1 Attachment B-SW8 130412-Pond Design Data 10116/18 Phase 1 Phase 3 Pond 1 Pond 2 Pond 37 Pond 1 Pond 2' Pond 3 P• • Pond 5 Pond 6 10712717 10/1211 10/12/17 DATE racy' 10/12117 10112/17 10/12,17 10/12."1r 10/12/17 10r16118 10+12117 DATE Tat ivb.Phase j 113t1C 3A.3(3A 2B Section 261 lumber of Lots Xi 31 36 29 1fa v _. 3273.32d, 3256-3361 .atNumbers I 1430 33033317. 13332 3231-327232274311 Ned Reerlcisd BUAILM . 4500' 4600 - 6 4..500 4500 4500 4500 a 4,600 4,500 a 4.51 tub Sulejee 1995 1995 1395 1995 1995 4995 2017 2000 2017 ..

No design changes were made. The permit was maintained under the 1995 rules(1.0 inch). 5/16/2014 Adjacent permit,SW8 131207 for Phase 4 was issued. (Phase 4 is across River Road directly on the river.) 12/6/2016 Partial Certification(Phase 3 Pond 2 only) 6/15/2017 An application was submitted to change the designs of Phase 3 Pond 4&Phase 3 Pond 6. 8/24/2017 During the review,DEMLR found that the project's plans did not match the configuration on Google Earth,and so a site inspection was a There are ponds not built per the plan,and there is unpermitted construction. It also appears that unpermitted lots have been sold with( recorded deed restrictions,and the impacted ponds have not been designed to accommodate full build-out from those lots. 10/12/2017 1.Modification Issued: The permit was modified to change the designs of Phase 3 Pond 4&Phase 3 Pond 6. (All impervious area was do 1.5 inches per the 2017 rules.) 2.Second Notice of Inspection Issued: The modification issued on this date DOES NOT address the non-compliant items in the August 2, inspection. A response to the August 24,2017 inspection was due on September 25,2017,but has not been received. 8/9/2018 Meeting between Kelly Johnson(DEMLR),Anthony Mills(DR Horton),and Tim Clinkscales,PE. The permit was in-house for a modificatio application did not include all items that were needt#l. It was determined that Ph3/Pond 5 would be modified under the current applicat that Ph3/Pond 4,Ph3/Pond 6,and Ph1/Pond 3 would be modified under a future modificaiton. These ponds were reportedly designed at 4,500sf/lot,deed restrictions were recorded at 4,500sf/lot(8K745/PG0986),but the permit requires 4,000sf/aot. (It was unclear if phi/P. needed to be modified as well. There was inconsiste wN 0., 1 . r• _ r iect also needed maintenance pi and the coon s need to be certified. 10/16/2018 Permit modification for Ph3/Pond 5. This pond has been modified to move it from outside Keekie Loop to inside Keekle Loop Iftraussaisr Tim, At least one of the ponds being modified is increasing its impervious area. (Ph3/Pond 4 is increasing from 148,155sf to 165,092sf). That makes the project a major modification. The package was submitted as a minor modification and is therefore being returned. Additionally; 2 1. You are modifying four ponds(Ph1/Pond 3, Ph3/Pond 2, Ph3/Pond 4,and Phi/Pond 6). But, I only have the calculations and supplement for Ph3/Pond 2? (If the elevations changed on the O&M,then we need that revised, too.) The ponds are not being modified, I have just updated the chart to match all the plans/calculations that were approved in the October approval. See above. 2. I also see that Ph3/Pond 2 is adding 91,792sf of offsite drainage area. Is that being accounted for at full build- out? The offsite was in the original permit and it includes the existing Belville Elementary School. This permit should reference a permit for the school if there was offsite? I will have to look into that. 3. The deed restrictions form has been submitted showing that the revised deed restrictions would be recorded. But, I think we had discussed that many of these lots had already been sold under deed restrictions for 4,500sf. Some lots are being reduced below that amount. We need the revised and recorded restrictions. These are the per lot given to me by client,will make sure get copy of recorded deed restrictions. 4. The revised permit Attachment B summarizing the data per pond references the deed restrictions table for three ponds. But,the deed restrictions table isn't per pond? As stated above, can update but same as October approval. See above. 5. I didn't receive revised plans. But, all four ponds drainage areas are changing and at least two ponds have lowered the temporary pool. Plan changes are needed. No plans have changed same as October approval. See above. 6. Attachment B isn't fully filled out. Respectively let me know what else to fill out.The number of lots to Ph1/Pond 2. 7. I don't see the Plan of Action in this package. Plan of action is on the response letter that was provided 8. I have not reviewed all of the previous correspondence to ensure that this is a complete list of items that are missing. Please ensure that any other items previously discussed are addressed.All items have been addressed,the only one to update is the deed restriction per pond on Phase 3 Pond 4 I would ask for you not send back with this information that BUA has not increased and waiting on copy of recorded deed restrictions and breakdown, please let me know you received this email Thanks Tim Clinickales FE, PLS PARAMOUNTE ENGINEERING, INC 122 Cinema Drive Wilmington, NC 28403 OFFICE: (910) 791-6707 CELL: (910) 520-1991 FAX: (910) 791-6760 www.naramounte-eng.com From:Johnson, Kelly<kellv.o.iohnson@ncdenr.gov> Sent:Tuesday, October 16, 2018 1:42 PM To: Michael C Loiacono<MCLoiacono@drhorton.com>;Tim Clinkscales<tclinkscales@paramounte-eng.com>; Anthony E Mills<AEMills@drhorton.com> Cc: Ian E Flannery<IEFlannery@drhorton.com>;Stew Daniel Gunn<SDGunn@drhorton.com> Subject: RE: [External] RE:SW8 130412 Hawkeswater at the River Andy&Tim, This attached permit was issued today.

Built upon area includes, but is not limited to, structures, asphalt, concrete, gravel, brick, stone, slate, coquina and parking areas, but does not include raised, open wood decking, or the water surface of swimming pools. 7. Each lot will maintain a 30**foot wide vegetated buffer between all impervious areas and surface waters. **50 foot for projects located in the 20 coastal counties. 8. All runoff from the built-upon areas on the lot must drain into the permitted system. This may be accomplished through a variety of means including roof drain gutters which drain to the street, grading the lot to drain toward the street, or grading perimeter swales to collect the lot runoff and directing them into a component of the stormwater collection system. Lots that will naturally drain into the system are not required to provide these additional measures.

SY:� Stormwater Permit Form 7: Minor Modification Page 2 of 2 Oct 6,2017 DESIGN NARRATIVE For this minor modification,no plans that have been submitted in the past are being changed. The two items that are being submitted are the updated impervious per lot for Phase 3A Section 2C and Phase 1B/1C. The updated impervious per lot is per the latest lots sold or guaranteed within the neighborhood. These are reflected as attachments to the signed deed restrictions. The second update or clarification involves the Phase 3 Pond 2 drainage area that includes the townhomes and lots along Hawkeswater Blvd. In the initial approved permits, the townhomes were part of the future allocation in the drainage area. The items that were designed in 2013 are provided in this submittal set, these calculations are exactly what was provided back in May 2018. As part of the update,the attachment B has been updated for this pond and changes in red. Since we have the townhomes designed and built, the actual impervious to the pond is less and reflected as such. Also provided the supplement to match the calculations.

Phase 2 will consist of 17.7 acres located within the Hawkeswater at the River development off of previously constructed Morecamble Blvd and behind Beivi.11e Elementary School. The development is off NC 133 just outside of Leland. Phase 2 consists of 84 multi-family units on the 177 acres. The pond shown is sized for 25.12 acres in permit SW8 060334M0D, this is labeled as Pond#2,Phase 3. The pond was sized using the same criteria shown in the approved permit, the future development will consist of single family lots that will submitted for approval upon construction documents being produced.. The project is within a drainage basin which drains to the Cape Fear River. The receiving stream is the Brunswick River (SC). The runoff will be conveyed into the wet detention pond via a strorm drainage system. The runoff will be controlled in the ponds through the use of outlet structures for primary control and spillways for greater rainfall events. The impervious area was calculated.by taking into the account the roadways, sidewalks, multi-family units,amenity center and future single family lots. In addition to this requirement,they will be designed to handle the pre/post requirements from Brunswick County. MAINTENANCE Contractors shall be responsible for periodic inspection and maintenance of all indicated erosion control devices in accordance with the plans and specifications. In addition, inspection and any necessary maintenance will be required immediately following any significant storm event.. Sediment will need to be removed from behind silt fencing as described on the Erosion Control Plan. Vegetative cover will be fertilized and reapplied as necessary to promote a vigorous stand.

Notice of Deficiency: The original NoD was issued on December 14. 2017. The DEMLR has been working with the permittee to achieve compliance. 2. Upcoming Minor Modification: As discussed at the August 9, 2018 meeting between Kelly Johnson(DEMLR),Anthony Mills(DR Horton), and Tim Clinkscaies, PE, additional modifications are needed to the ponds that were not covered by the application permitted on October 16, 2018. a. Reallocation: At least three ponds(Ph3/Pond 4, Ph3/Pond 6,and Phi/Pond 3) will need to reallocate their impervious area. i. One additional pond(Ph3/Pond 2)may also need to be revised. It is unclear from the data submitted if the temporary pool is at 15.0ms1 (as it was in 2017)or 14.0msl(as it appeared in some data submitted during this review.) The permanent pool is 12 and temporary pool at 14,this matches the plans and calculations provided in May. I have updated overall table and Phase 3 Pond 2 supplement. Since older rules used supplement to match ii. The ponds were designed to hold 4,000sf from each lot, but the deed restrictions gave residents 4,500sf!lot. Not all of the lots have been sold. You all plan to re-allocate the available impervious such that the total impervious previously permitted for these ponds will not change, and therefore no pond re-design will be needed. Please note that if pond(s) need to be redesigned then that may trigger a major modification rather than a minor modifiration.No modification needed,the BUA is the same, the deed restrictions provided on 11/19 reflect such b. Complete Application: Please update Attachment B and fill it out completely upon your resubmittal. (Please verify the data in the shaded areas to ensure that the sub phases, number of lots, lot numbers, the impervious areas accounted for during the design of the ponds, and the pond pump horsepower are correct.) Only items updated is Phase 3 Pond 2— Townhome and 25 lot section behind school 3. Deed Restrictions: a. B2745/P0986 was recorded on 2/2/08, and it gives 4,500sf/lot for the entire subdivision(Phases 1,2,and 3). b. Deed restrictions will need to be re-recorded for Ph3/Pond 4, Ph3/Pond 6,and Ph1/Pond 3 to reflect their new allocations. These were part of 11/19 submittal 1 2 2 CINEMA 4 R I V E, W I L M I N G T 4 N , KID 2 8 a 0 3 :° H . (9 1 4 1 7 9 1 - 6 7 0 7 F A X : ( 9 1 0) 79 1 • 6 7 6 0 PARA . Request for Plan of Action: 1. Please submit a new Plan of Action to bring the project into compliance. It should provide the following: a. The minor modification is to be submitted by November 19.2018. b. The certifications will be submitted for all of the ponds within three months of the issuance of the permit resulting from the November 19, 2018 application. (For clarification, all ponds in the subdivision need to be certified including the ponds that DR Horton purchased out of foreclosure.) Plan of action for the existing ponds,we have completed a survey of the ponds, reviewed the calculations and worked with Horton on the updates required to allow us to certify the ponds. a. Phase 3 Pond 1 —the forebays need to be re-established, we are working with contractor to re-establish, all other items meet the permit, (both forebay's)are to be re-established b. Phase 3-Pond 3—Pond was not constructed, and lots not built on cul de sac c. Phase 3-Pond 7—need to raise orifice to the permitted elevation 6, currently built at 5.3',all areas good d. Phase 1 —Pond 1 —will certify when deed restrictions recorded e. Phase 1 —Pond 2-need to raise orifice to elevation 18, permitted at 17,for some reason the surface area required is at elevation 18, also forebays to be re-established, when constructed, will provide items to place in supplement.

On the deed restrictions,we have worked with Horton to determine which lots are sold and current BUA, enclosed is a chart their attorney is using to record the restrictions,they should be done early next week. As we discussed, all the impervious numbers stay the same with the BUA/lot only thing being updated 2.) Plan of action for the existing ponds, we have completed a survey of the ponds, reviewed the calculations and worked with Horton on the updates required to allow us to certify the ponds. a. Phase 3 Pond 1—the forebays need to be re-established,we are working with contractor to re-establish, all other items meet the permit, (both forebay's) are to be re-established b.

Here are my notes from the meeting. 1. This Modification: a. Phase3/Pond 5: i. This pond will be modified to move it from outside Keekle Loop to inside :eelcle Loop. It is intended to be reviewed under the 2008 rule. ii. Please submit: 1. Sealed supplement cover 2. 2''set of Phase 3/Pond 5 plans 3. O&M for Phase 3/Pond 5 iii. I will review the data submitted in the near future. b. Townhomes(Phase 2): i. Phase 2 is located inside the drainage area for Phase 3 Pond 2. ii. There is an amenity pond, but the impervious drains towards the permitted pond. iii. The configuration for the townhomes was not previously permitted, and the configuration will become permitted in this modification. 2. Future Actions: a. Upcoming Minor Modification: Three ponds(Ph3/Pond 4, Ph3/Pond 6, and Phi/Pond 3) :.fill need to reallocate their impervious area. i. The pond was designed to hold 4,000sf from each lot, but the deed restrictions gave residents 4,500sf/lot. ii. Not all of the lots have been sold. I understand that you all will re-allocate the available impervious such that the total impervious previously permitted for these ponds will not change. b. Deed Restrictions: i. B2745/P0986 was recorded on 2/2/08,and it gives 4,500sf/lot for the entire subdivision (Phases 1, 2, and 3). ii. The Townhomes/Phase 2 have been given 4,500sf/lot for each residence (not building). But, these homes are sold without land. The owners cannot build outside of their building, and so DEMLR does not require deed restrictions in this situation. I will make a note of this in the permit. iii. Deed restrictions will need to be re-recorded for Ph3/Pond 4, Ph3/Pond 6, and Ph1/Pond 3 to reflect their new allocations once that minor modification is issued. c. Plan of Action: Please submit a new Plan of Action to bring the project into compliance. It should provide dates that the minor modification will be submitted, maintenance will be completed, and certifications will be submitted for all of the ponds(not just the ponds that DR Horton developed).
