Remarks: 1. The present layout of roadway infrastructure for the proposed project does not depict logical termini leading to the potential for further/future jurisdictional impacts associated with roadway impacts on adjacent parcels, therefore the Corps is unable to determine whether the activity authorized under the nationwide permit will result in more than minimal individual or cumulative adverse environmental effects. Please provide further information on the potential for adverse cumulative effects due to stub roads to adjacent properties. On June 9, 2016, we had a meeting to discuss the potential cumulative impacts related to adjacent properties. To the north and east, it was determined to be not an issue. There are no features present on the USGS to indicate future cumulative impacts. To the south, Ed Tang the project engineer explained that Meritage Homes (Meritage) had contemplated purchasing the southern parcel and that Meritage had paid to have a wetland & stream delineation completed on this property, in addition to a preliminary development plan. The plan was designed such that the stub to the south would enter the property in the uplands and stream impacts were avoided. Brian Ketcham, the applicant and Meritage Homes & Director of Entitlement, indicated that there was not enough viable land to get the required lot yield, in addition to the Town of Apex requirement that 30% be set aside for commercial development. With these issues, Meritage walked away from the parcel of land. 2. Your avoidance and minimization justification is insufficient. Please provide a more robust justification for the current location of the stream and wetland crossings, and if/why other crossing options that could have less impacts to jurisdictional waters were not utilized. Specifically why/why not road crossing 2A, 513 cannot be moved to avoid wetland impacts at those locations. As well as a detailed explanation for not utilizing bore and jack methods to avoid wetland and stream impacts associated with sewer line installation. In the June 910 meeting, it was discussed that the Town of Apex would require Cast In Place (CIP) retaining walls at the wetland crossing locations 2A and 5B and that a comparison of the cost of the CIP walls and the reduction in compensatory mitigation vs. the existing proposed impacts and current mitigation should be completed to determine the cost difference in each scenario. To complete this exercise, Ed Tang sketched new impact areas with a reduction in the wetland impacts that would be reasonably expected with the use of CIP retaining walls (see attached exhibits). Brian Ketcham contacted Oak City Contracting, LLC and requested a bid price on the CIP retaining walls for the two crossings (see attached Bid), and I re -calculated the wetland mitigation fees with the wetland impact reductions. The wetland impact reduction totaled 0.099 acres. In reviewing the decrease and the cost associated with the CIP walls, there would be an estimated increase of $193,900.00 for the CIP walls and no reduction in compensatory mitigation because we had to utilize the NCDMS for mitigation and NCDMS only accepts mitigation in 0.25 increments (i.e. 0.72 vs. 0.52). Bore and Jack methods were not utilized at sewer line crossings because preliminary boring studies indicated bedrock along the streams for the project. 3. Furthermore, the Corps believes that the greenway trail at impact areas 3 and 4A can be avoided by relocating the greenway away from jurisdictional features, or the utilization of foot bridges that require no impacts to jurisdictional waters. Please revise the greenway trail to minimize impacts or provide a detailed explanation of why this plan cannot be practically accomplished, reduced or reconfigured to better minimize impacts to jurisdictional features. Impacts 3 and 4A have now been modified to include pedestrian bridge crossings to avoid permanent stream impacts in these locations. However, there was proposed gravity sewer at these crossing locations so now we are proposing only temporary stream impacts at impact locations 3 & 4A. This addition of pedestrian bridges has reduced the Permanent and the Permanent, No Permanent Loss stream impacts by 143 linear feet. Please see attached updated Exhibits 3, 4, 12 & 13, and the "typical Ped Bridge for Greenway".

Avoidance and Minimization la. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. The applicant contracted with S&EC to complete a wetland and Jordan Watershed Buffer evaluation for the entire property and the offsite areas in order to identify the natural resources so that the project designers could design a site plan that would minimize impacts to wetlands & streams to the maximum extent practicable. The proposed project includes eleven (11) impact areas that include impacts to jurisdictional wetlands, streams and associated riparian buffers. Impact 1 includes a wetland impact necessary for a greenway, and bypass drainage piping & pad from existing stormwater directed from New Hill Olive Chapel road. This proposed impact will result in 0.013 acres of permanent wetland impacts. This impact has been minimized by moving the greenway to the northwest to minimize wetland impacts. Impact 2A includes a wetland road crossing necessary to provide access to the northern portion of the property. This proposed impact will result in 0.123 acres of permanent and 0.017 acres of temporary wetland impacts. This impact has been minimized by crossing the wetland at a near perpendicular angle. Impact 2B includes a wetland impact associated with onsite gravity sewer. This proposed impact will result in 0.005 acres of temporary wetland impacts. Impact 3 includes a stream crossing necessary for onsite gravity sewer. This proposed impact will result in 49 linear feet of temporary intermittent stream impacts. Impact 4A includes a stream crossing necessary for onsite gravity sewer. This proposed impact will result in 41 linear feet of temporary perennial stream impacts. Impact 48 includes a stream impact associated with onsite gravity sewer. This proposed impact will result in 33 linear feet of permanent, no permanent loss (i.e. keyed in riprap) stream impacts. Impact 5A includes a wetland impact associated with onsite gravity sewer. This proposed impact will result in 0.010 acres permanent, no permanent loss and 0.019 acres of temporary wetland impacts. This impact has been minimized by utilizing a narrower permanent maintenance corridor (i.e. permanent conversion). Impact 5B includes stream and wetland impacts for a road crossing necessary to provide access to the eastern portion of the property. The proposed wetland impacts will result in 0.209 acres of permanent and 0.020 acres of temporary impacts. The proposed stream impacts will result in 19 linear feet of temporary, 90 linear feet of permanent, and 69 linear feet of permanent, no permanent (i.e. dissipater) perennial stream impacts. This impact has been minimized by utilizing head walls and retaining walls at the stream crossing, and crossing the wetland and stream at a near perpendicular angle. Impact 5C includes a wetland impact associated with onsite gravity sewer. This proposed impact will result in 0.019 acres permanent, no permanent loss and 0.018 acres of temporary wetland impacts. This impact has been minimized by utilizing a narrower permanent maintenance corridor (i.e. permanent conversion). Impact 6 includes a stream impact associated with offsite gravity sewer. This proposed impact will result in 41 linear feet of permanent, no permanent loss (i.e. keyed in riprap) stream impacts. Impact 7 includes a stream impact associated with offsite gravity sewer. This proposed impact will result in 53 linear feet of permanent, no permanent loss (i.e. keyed in riprap) stream impacts. Post construction, all temporary stream impacts will be brought back to pre -construction elevations and the stream banks will be stabilized, additionally all temporary wetland impact areas will be brought back to original contours and will allowed to re - vegetate with the natural seed source. The applicant is aware of the regional conditions associated with the Nationwide Permits 29 & 12. With respect to residential development conditions (NWP 29 -Regional Conditions section 4.0) the applicant does not anticipate any impacts to streams or wetlands associated with stormwater facilities, there are no impact associated with single-family recreation facilities, there are no permanent wetland or stream rills proposed within the floodwayRloodplain and the stream classification for this project is WS -IV, NSW (i.e. not Outstanding Resource Waters, High Quality Waters, Coastal Wetlands or wetland adjacent to these waters). With respect to utility line activities (NWP 12 -Regional Conditions section 4.0) the applicant does not propose to utilize directional drilling,boring methods to install the sanitary sewer because considering the size of the site and the number of utility crossing being required by the Town, it is cost prohibitive. Furthermore, the applicant recognizes that the proposed temporary impacts for the sanitary sewer crossings will be for the minimum period of time required to complete the activity and that the wetlands and stream must be returned to its pre -construction elevations and contours, that the proposed sanitary sewer crossings construction corridor and easements will not exceed 40 feet in width, that the proposed sanitary sewer crossings should not cross federally maintained channel and interfere with navigation, that this proposed sanitary sewer crossing is not a communication line or an electrical line and therefore should comply with 4.5 & 4.6. And finally, the applicant is proposing that all temporary impact to wetlands will be restored to pre -construction contours and will be re -vegetated, and a mitigation plan is included within Section D.2. a, which includes compensatory mitigation In -Lieu payment for the conversion of forested wetlands to a herbaceous permanently maintained corridor. Rip -rap will be avoided to the maximum extent practical. 1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. Per the project engineer., Contractor shall use pump arounds and temporary bypass channels to construct stream crossings and work in the dry periods. Silt fence and tree protection fence will minimize the footprint of impacts where contractors shall not encroach outside the work area. Sediment traps basins will be constructed in the areas upland of wetlands and streams to minimize turbidity impacts to receiving waters. Standard residential construction equipment and techniques will be utilized. 2.
