Signature: Submittal Date: Is filled in autorratically. Hey Alex, I have reviewed the PCN and plans for the above referenced project, and I have a few comments/questions that need to be addressed prior to proceeding with review and issuance of the permit verification. 1) It appears that the PCN table of impacts does not match the submitted impact maps. One example is Impact #7 (Temporary Stream Impact – Sewer Installation) is not listed on the PCN. Additionally, the impact numbers from the Plans should match the PCN table. For example, Impact #1 on the impact maps is listed as Impact W3 on the PCN. Please update the PCN and Plans accordingly. Please find the updated impact maps and tables attached to the resubmittal. 2) On the PCN and plans, itemize stream/wetland impacts into separate parts: permanent impacts due to the culvert, permanent (no functional loss – if installed per regional condition 4.1.6) impacts due to rip rap, and temporary impacts due to dewatering or construction. For example, Impact#1 could be broken out into three different impacts. Impact #1 could be permanent wetland impacts for installation of the culvert, Impact #2 could be permanent (no functional Loss) wetland impacts for the below dissipator pad, Impact #3 could be for the temporary wetland impacts for construction activities. Please update the PCN and Plans Accordingly. Please find the updated impact maps and tables attached to the resubmittal. 3) It appears as though the impacts for the riprap dissipation pads for the two crossings are not being addressed on the PCN table or Impact Plans. Dissipator pads when installed per regional condition 4.1.6 are considered a permanent (no functional loss) impact. Additionally, the plans show riprap only below the culvert at both crossings, however, the cross section sheet depicts riprap above and below the culvert. Please update the PCN and Plans accordingly. Please find the updated impact maps with revised rip rap labeling. This rip rap will be installed per regional condition 4.1.6. 4) A Purpose and Need attachment is referenced in the ePCN, however, I did not receive it. Please submit Purpose and Need attachment when submitting additional information. Purpose and Need attachment should address existing conditions, purpose of the project, project details, details about proposed activities and construction techniques and avoidance and minimization. Please find included Purpose and Need. 5) Please update the proposed compensatory mitigation plan to include details such as proposed mitigation ratios. A 2:1 mitigation ratio is typical unless evidence of low function is provided (NCWAM form). For example, during our pre-application meeting we talked about the possibility of the of the wetland impacts in the drained pond being calculated at a lesser ratio. Please update the PCN accordingly. The drained pond exhibits relatively low function as reflected in the included NCWAM form and a mitigation ratio of 1:1 is appropriate. 6) Based on the submitted application the proposed activities will result in 105 linear feet of permanent (with loss) stream channel impacts; and therefore stream mitigation is not required. Based on Regional Condition 3.2, mitigation is typically required when functional loss of stream channel impacts are greater than 150 linear feet. Please update the PCN accordingly. It is understood that the impact to S1 of 105 linear feet will not require mitigation. 7) Please provide a brief description of the habitat in the impact areas in order to verify that potentially suitable habitat for federally listed species on IPaC is not present. We provide these habitat descriptions to USFWS for their concurrence. The iPaC results include three species of interest, Atlantic Pigtoe (Fusconaia masoni), Red-Cockaded Woodpecker (Picoides borealis), and Michaux’s Sumac (Rhus michauxii). The Atlantic Pigtoe inhabits higher quality streams and is not anticipated to utilize the wetlands on the Holt site. The impact to S1 occurs in a breached dam that was not flowing a year ago. Additionally, the stream flows out of a drained pond with heavy dense sediment that would not support the life history of the Atlantic Pigtoe. Similarly, the impact at S2 occurs in a reach that flows directly downstream from the pond site and does not appear to provide adequate habitat for the mussel. The Red-Cockaded Woodpecker inhabits old growth stands of longleaf pine. There are no stands of appropriate habitat in the assessment area so the RCW is not expected to be present or adversely affected by the project. With regard to Michaux’s Sumac, a portion of the site includes maintained agricultural land and lawns, which are potential habitat for this species. A pedestrian survey of the areas with potential habitat did not result in any observation of Michaux’s Sumac; therefore, the project is unlikely to adversely affect the plant. 8) Additional information may be required when evaluating responses to the remarks above. Please let me know if you have any questions/comments.

A Minority‐Owned Business      Courtyards on Holt  Buffer and Stream Impacts Purpose and Need / Avoidance and Minimization Statement  Holt Road and Catlette Street  Apex, North Carolina  F&R Project No. 59Y‐0017   PURPOSE AND NEED    Epcon Communities is in the process of developing a single‐family residential subdivision on  historically agricultural property along Holt Road in Apex, NC. The demand for housing in the  area is high and this project will add to the number of housing units available. This Purpose and  Need statement provides general project information and a list of the design aspects utilized to  reduce and eliminate wetland and stream impacts to the maximum extent practicable.  The project site is located along the west side of Holt Road, directly across from the intersection  with Howell Road in the Town of Apex, Wake County, North Carolina. The Holt Assemblage  consists of six contiguous parcels totaling 29.27 acres in size, as well as an off‐site proposed  sewer  easement  extending  to  the  west  of  the  project  site.  The  Assemblage  is  currently  improved  with  five  one‐story,  single  family  residential  housing  structures,  which  will  be  removed prior to development.  The proposed project is considered a major residential subdivision and thus certain program  elements are required by the local jurisdiction (i.e., the Town of Apex). These requirements  include stormwater management systems and structures, ingress and egress requirements for  the subdivision, water and sewer utilities, and other amenity requirements associated with the  development of a major subdivision.   A wetland and stream delineation for the Holt site was field‐approved by the US Army Corps of  Engineers (USACE) on August 14, 2018 (SAW‐2018‐01551) and a Riparian Buffer Determination  was issued on August 3, 2018 by the Town of Apex (Apex 18‐006). The Town of Apex has been  delegated authority from the North Carolina Department of Environmental Quality (DEQ) to  review  and  approve  riparian  stream  buffer  calls.  The  delineation  efforts  resulted  in  the  identification  of  three  wetlands,  two  streams,  and  one  pond  within  the  assessment  area.  Additionally, a further Riparian Buffer Determination was issued by the Town of Apex (Apex 19‐ 002) on November 19, 2019, which included  the adjacent property to the east of the Holt site  (i.e., Grimley Property). That authorization included a determination for the upper reaches of  the main stream feature that flows through the project site. Features identified during each of  Epcon Communities  2  Courtyards on Holt  F&R Project Number: 59Y‐0017    March 14, 2020  the USACE field‐approvals and Town of Apex Riparian Buffer Determinations are shown on the  attached project plans and Impact Maps.   Additionally, an off‐site sewer easement is proposed in order to tie the proposed subdivision  into the existing sewer infrastructure. This easement extends to the west of the project site  approximately 1,700 feet, running along the south side of an unnamed perennial stream to  Twin Creek Road, then west within Roosedall Court before going north and crossing a perennial  stream and terminating at an existing manhole. One small wetland (approximately 1,600 SF in  total  size)  will  be  impacted  by  this  easement  in  addition  to  buffer  impacts  and  temporary  impacts associated with the stream crossing. The additional features being impacted by this  proposed easement were not field reviewed by James Lastinger as part of the approval from  August 14, 2018; however, during a pre‐application meeting with USACE Project Manager Lyle  Phillips, it was indicated that a field visit would not be necessary and the open cut crossing of  the stream is to be classified as a temporary impact.    AVOIDANCE AND MINIMIZATION    In order to comply with specific requirements of the Town of Apex, the subdivision is designed  with  two  ingress/egress  routes  connecting  the  site  to  public  roads,  as  required  by  local  regulations.  Because  of  this,  a  crossing  that  impacts  the  former  on‐site  pond  area  is  unavoidable. The proposed Phillips Branch Street will provide the northern entrance from Holt  Road is aligned along the existing dam in order to create the least amount of impacts to the  pond area as possible. A number of steps were taken during the planning stages of this project  in an effort to substantially reduce and, in some cases, eliminate wetland, stream, and riparian  buffer impacts to the maximum extent practicable. Some of the specific measures taken to  avoid and minimize impacts to the former pond area and other identified wetland and stream  features and buffers on the project site and adjacent areas are documented below:   A horizontal curve in Phillips Branch Street has been introduced in an effort to move the  street alignment as far onto the existing dam structure as possible  and  out  of  the  drained  pond  area,  thereby  reducing  wetland  impacts  to  the  maximum  extent  practicable within the former pond.   Utilities are located within the Phillips Branch Street at wetland and stream crossing  locations in an effort to limit environmental impacts in those areas.  Epcon Communities  3  Courtyards on Holt  F&R Project Number: 59Y‐0017    March 14, 2020   A headwall has been extended along the east side of the Phillips Branch Street within  the footprint of the former pond area in order to reduce the width of the roadway  support system, thereby reducing impacts.   All utilities along Catlette Street are being kept in the R/W to avoid the wetland area in  the SW corner of the property.   Headwalls  and/or  retaining  walls  have  been  added  to  the  Catlette  Street  wetland  crossing in order to reduce the wetland impacts associated with this crossing to the  maximum extent allowed per local regulations.   Catlette Street near Holt Road is being moved to the south from its current location in  an effort to reduce impacts to the stream buffer at that location.   The outlet pipes from SCM 1, 2 and 3 have been pulled back to the edge of the former  pond  area  as  much  as  possible  while  maintaining  flow  to  minimize  any  impacts  to  wetlands that may remain in these areas.   SCM 1: the storm outlet was pulled back approximately 100’ to daylight at the edge of  the former pond. This structure has also been redesigned to eliminate slopes into the  pond area and existing wetland areas.   SCM 2: only impact is extension of the outlet pipe to the channel due to elevation  constraints.   SCM 3: no wetland impacts associated with the riser outlet of pond grading.   Sanitary sewer near Lot 23 has been moved south out of the footprint of the former  pond area to minimize impacts of the sewer installation and future maintenance within  wetland areas.   Storm routing has been shifted north to the edge of Lot 66 to minimize impacts to the  former pond area at this location.   Sewer easement widths are established by the Town of Apex based upon sewer depth.  Sewer routing has been kept as shallow as possible within wetland crossing areas to  reduce maintained easement widths and impacts.   The sewer access for the adjacent property to the east, shown just north of SCM #2, is  proposed as directional drill to eliminate the impacts to the wetland, stream, and buffer  in this location.  The  planning  measures  listed  above  have  been  taken  to  effectively  reduce  the  amount  of  wetland and stream impacts to the greatest extent practicable.  These efforts include realigning  the roadways in the subdivision, changing the location and size of utilities, providing for low  Epcon Communities  4  Courtyards on Holt  F&R Project Number: 59Y‐0017    March 14, 2020  maintenance  sleeved  sewer  piping  and  smaller  maintained  easements,  and  proposing  headwalls to reduce fill slopes into environmental features. Additionally, the proposed wetland  impact areas are generally lower quality systems. It is important to look at the overall plan for  the subdivision and note that almost all the lots for the neighborhood are positioned so that  they are away from the sensitive environmental features. Impacts to wetlands, streams, and  buffers are almost exclusively related to the installation of roadways and utilities. The bulk of  the impacts are concentrated at the road crossing, where impacts have been reduced as much  as possible while still constructing a road that meets design criteria. It is our opinion that these  efforts satisfy the requirement to avoid wetland and stream impacts where possible and reduce  impacts where necessary to the maximum extent practicable.  Sincerely,      Alex D. Aycrigg, MS, PWS

Consider alteration to the ground surface (GS) in the assessment area and vegetation structure (VS) in the assessment area. Compare to reference wetland if applicable (see User Manual). If a reference is not applicable, then rate the assessment area based on evidence of an effect. GS A A Not severely altered B B Severely altered over a majority of the assessment area (ground surface alteration examples: vehicle tracks, excessive sedimentation, fire-plow lanes, skidder tracks, bedding, fill, soil compaction, obvious pollutants) (vegetation structure alteration examples: mechanical disturbance, herbicides, salt intrusion [where appropriate], exotic species, grazing, less diversity [if appropriate], hydrologic alteration) 2.Surface and Sub-Surface Storage Capacity and Duration – assessment area condition metric Check a box in each column. Consider surface storage capacity and duration (Surf) and sub-surface storage capacity and duration (Sub). Consider both increase and decrease in hydrology. Refer to the current NRCS lateral effect of ditching guidance for North Carolina hydric soils (see USACE Wilmington District website) for the zone of influence of ditches in hydric soils. A ditch ≤ 1 foot deep is considered to affect surface water only, while a ditch > 1 foot deep is expected to affect both surface and ditch sub-surface water. Consider tidal flooding regime, if applicable. Surf A A Water storage capacity and duration are not altered. B B Water storage capacity or duration are altered, but not substantially (typically, not sufficient to change vegetation).

Consider surface pollutants or discharges (Surf) and sub-surface pollutants or discharges (Sub). Examples of sub-surface discharges include presence of nearby septic tank, underground storage tank (UST), etc. Surf Sub A A Little or no evidence of pollutants or discharges entering the assessment area B B Noticeable evidence of pollutants or discharges entering the wetland and stressing, but not overwhelming the treatment capacity of the assessment area C C Noticeable evidence of pollutants or discharges (pathogen, particulate, or soluble) entering the assessment area and potentially overwhelming the treatment capacity of the wetland (water discoloration, dead vegetation, excessive sedimentation, odor) 6.Land Use – opportunity metric Check all that apply (at least one box in each column). Evaluation involves a GIS effort with field adjustment. Consider sources draining to assessment area within entire upstream watershed (WS), within 5 miles and within the watershed draining to the assessment area (5M), and within 2 miles and within the watershed draining to the assessment area (2M). Effective riparian buffers are considered to be 50 feet wide in the Coastal Plain and Piedmont ecoregions and 30 feet wide in the Blue Ridge Mountains ecoregion.

B Pocosin is < 90% of the full extent of its natural landscape size. 13.Connectivity to Other Natural Areas – landscape condition metric 13a.Check appropriate box(es) (a box may be checked in each column). Involves a GIS effort with field adjustment. This evaluates whether the wetland is well connected (Well) and/or loosely connected (Loosely) to the landscape patch, the contiguous metric naturally vegetated area and open water (if appropriate). Boundaries are formed by four-lane roads, regularly maintained utility line corridors the width of a four-lane road or wider, urban landscapes, fields (pasture open and agriculture), or water > 300 feet wide. A A ≥ 500 acres B B From 100 to < 500 acres C C From 50 to < 100 acres D D From 10 to < 50 acres E E < 10 acres F F Wetland type has a poor or no connection to other natural habitats 13b.Evaluate for marshes only. Yes No Wetland type has a surface hydrology connection to open waters/stream or tidal wetlands. 14.Edge Effect – wetland type condition metric (skip for all marshes) May involve a GIS effort with field adjustment. Estimate distance from wetland type boundary to artificial edges. Artificial edges include non-forested areas ≥ 40 feet wide such as fields, development, roads, regularly maintained utility line corridors and clear-cuts. Consider the eight main points of the compass. A No artificial edge within 150 feet in all directions B No artificial edge within 150 feet in four (4) to seven (7) directions C An artificial edge occurs within 150 feet in more than four (4) directions or assessment area is clear-cut 15. Vegetative Composition – assessment area condition metric (skip for all marshes and Pine Flat) A Vegetation is close to reference condition in species present and their proportions. Lower strata composed of appropriate species, with exotic plants absent or sparse within the assessment area. B Vegetation is different from reference condition in species diversity or proportions, but still largely composed of native species characteristic of the wetland type. This may include communities of weedy native species that develop after clearcutting or clearing. It also includes communities with exotics present, but not dominant, over a large portion of the expected strata. C Vegetation severely altered from reference in composition. Expected species are unnaturally absent (planted stands of non- characteristic species or at least one stratum inappropriately composed of a single species). Exotic species are dominant in at least one stratum. 16.Vegetative Diversity – assessment area condition metric (evaluate for Non-tidal Freshwater Marsh only) A Vegetation diversity is high and is composed primarily of native species (<10% cover of exotics). B Vegetation diversity is low or has > 10% to 50% cover of exotics. C Vegetation is dominated by exotic species (>50% cover of exotics). Well WC Loosely 17.Vegetative Structure – assessment area/wetland type condition metric 17a.Is vegetation present? Yes No If Yes, continue to 17b. If No, skip to Metric 18. 17b.Evaluate percent coverage of assessment area vegetation for all marshes only. Skip to 17c for non-marsh wetlands. A ≥ 25% coverage of vegetation B < 25% coverage of vegetation 17c.Check a box in each column for each stratum. Evaluate this portion of the metric for non-marsh wetlands. Consider structure in airspace above the assessment area (AA) and the wetland type (WT) separately. A A Canopy closed, or nearly closed, with natural gaps associated with natural processes B B Canopy present, but opened more than natural gaps C C Canopy sparse or absent A A Dense mid-story/sapling layer B B Moderate density mid-story/sapling layer C C Mid-story/sapling layer sparse or absent A A Dense shrub layer B B Moderate density shrub layer C C Shrub layer sparse or absent A A Dense herb layer B B Moderate density herb layer C C Herb layer sparse or absent 18.Snags – wetland type condition metric A Large snags (more than one) are visible (> 12-inches DBH, or large relative to species present and landscape stability).
