Year 1 (2015) Monitoring Report Hofler Property, Project ID# 95355 2 2 2 2 3 4 5 9 ...... 14 ...... 19 ...... 32 1.0: PROJECT SUMMARY 1.1: Project Goals The project goals of the Hofler property per the approved mitigation plan are as follows: • Reduce sediment and nutrient loading from agricultural runoff • Improve downstream anadromous fish habitat and onsite wildlife habitat • Restore groundwater and surface water hydrology in heavily ditched areas • Restore natural drainage patterns where appropriate 1.2: Project Success Criteria Wetland hydrology data must consistently document the appropriate hydroperiod has been restored for all areas proposed for wetland mitigation. The targeted hydroperiod for the Hofler Property is 6% or greater. Planted vegetation will be considered successful if at least 320 three year-old planted stems/acre are present after year three. At year five, density must be no less than 260 five year-old planted stems/acre. At year 7, density must be no less than 210 seven year-old planted stems/acre. Additionally, planted vegetation must average 10 feet in height in each plot at year 7. Per the recommendations of the NCIRT, the following understory species were incorporated in the planting schedule on the condition they be exempted from the minimum 10 -foot height criterion and exempted from the calculation of average height as a measure of that success criterion: Button bush (C. occidentalis), Sweet bay (M. virginiana), Wax myrtle (M. cerifera), and Laurel oak (Q. laurifolia). These species will be included in the calculations for the survival criterion. All vegetative monitoring will follow CVS-EEP Protocol for Recording Vegetation -Version 4.0. Additionally, the project will strive to establish a variety of hydrologic regimes ranging from shallow inundated areas to intermittently saturated conditions, restoring diffuse flow patterns through what will ultimately be a forested wetland. The successful establishment of these conditions, mimicking nearby reference wetlands will help determine the overall success of the project. 1.3: Project Setting The Hofler property consists of +/- 345 acres, of which 27 acres have been designated for this project. The site consisted of a rectangular tract of land primarily being used for cotton and small grain production. The prior converted wetlands on the site had been extensively ditched and drained, lowering the local water table and diminishing aquatic habitat and water quality. The site drained from south to north to an unnamed tributary of Lassiter Swamp and Bennets Creek upstream of Merchants Mill Pond. The project site along with the surrounding areas has undergone expansive hydrologic alterations and excessive sediment and nutrient inputs from agricultural production resulting in overall water quality Page: 1 Year 1 (2015) Monitoring Report Hoffer Property, Project ID# 95355 degradation. The vicinity map is included with the CCPV in Appendix B. Table 4 in Appendix A contains additional information regarding the project's location and attributes. 1.4: Mitigation Components The mitigation components are 23 acres of non -riparian wetland restoration with a credit ratio of 1:1 (Restoration: WMU), please refer to Table 1 for more information. 1.5: Project Timeline Construction commenced on August 12th, 2014 with the installation of recommended erosion control practices and was completed on Oct. 14th, 2014. Planting was officially concluded on May 6th, 2015 (Table 2). Refer to Table 2 in Appendix A for the Project History and Reporting Timeline. 1.6: Design Approach A natural design approach focused on mimicking nearby wetlands, including non -riparian hardwood flats and swamp forests both in hydrologic regime and vegetative diversity. Grading was specifically formulated to provide storage for overland flow while creating densely vegetated plots interspersed with shallow diffuse flows. All of these features contribute to nutrient and sediment attenuation, improving downstream habitat and promoting diversity of ecological communities. The reference area for this project is a nearby mature pine/hardwood flat with the same soils and topography and similar hydrologic function. 1.7: Project Performance Rainfall for the period of April through November, 2015 totaled 32.03 inches which was slightly above the median of 30.52 inches for the 30 — 70 percent range during the same period. Hydrology within the project area was successful with an average across all nine monitoring gauges of 15.1% of the growing season. In order to meet the ten -foot height requirement, some older, taller trees were planted but many of them suffered top dieback or mortality possibly due to the fact that they were potted and not open grown, bare root stock. Wet site conditions may have put too much stress on these larger, root -bound trees. Future monitoring will determine the extent of the damage, but gains in height to meet the requirement were lost regardless of it. With the exception of plot 11, all the plots met or exceeded the success criterion for stems per acre. The site is covered with very heavy herbaceous vegetation and some stems that were not found during monitoring this year may well resprout and show up in subsequent years so stocking on that particular plot is not cause for concern just yet and is not noted on the CCPV.

Vegetation assessment was done according to the level 2 protocol specified by the Carolina Vegetation Survey. Hydrology monitoring wells were installed per ERDC TN -WRAP -00-02 "Installing Monitoring Wells/Piezometers in Wetlands" dated 2000. Groundwater levels were recorded using the U20-001-01 water level data loggers manufactured by Onset Computer. The loggers were installed in the wells per the manufacturer's instructions.

These comments are attached for your review. This mitigation plan was originally posted in January, 2014. Comments posted identified numerous concerns with the projects (see attached memo). Because of these comments, the plan was revised in March 2014, and reposted on March 6, 2014 for a second review. The deadline for comments was April 5, 2414. An initial review of the comments revealed that many of the comments from the first round of comments had not been addressed in the March mitigation plan revision. Prior to making a determination as to whether to approve this project, a third copy of the mitigation plan, dated May 2014, was received on May 29, 2014. This plan has subsequently been reviewed in light of the comments provided by NC'IRT members during the review. Most of the comments have been addressed in the recent version of the plan, including concerns regarding well placement, vegetation plots, appropriate hydroperiod, and the proposed species list for planting. Based on these modifications, we have determined that major concerns identified with the Draft Mitigation Plan have been addressed, and the mitigation plan is considered approved with this correspondence. Nevertheless, we believe it is important to note that the location and method of construction at the proposed site are not preferred, and effort should be made to avoid this type of project in the future. As a general rale, we do not believe that building berms around a restored wetland is an appropriate way to reestablish hydrology on a site. To begin with, this is not true restoration as you are establishing an entirely new hydrology regime on the site. Water flaw into and out of the wetland is severely restricted by the berms, and the outflow elevation for the entire site is controlled by "ditch plugs/check dams" (see discussion on page 23 of the mitigation plan dated May 2014). In addition, there is the potential that Page: 33 Year 1 (2015) Monitoring Report Hoffer Property, Project ID# 95355 berms maw be breached in the future though natural or anthropogenic means, which could affect the hydrology of the entire site. Lastly, constructing a wetland site in the middle of an agricultural field is not ideal as it drastically limits the connection between the site and forested wetlands adjacent to or downstream from the project. In this case, water flowing from the site must travel through more than ''/4 mile of ditch before it reaches the forested headwaters of Lassiter Swamp, limiting the benefit of the project and the ability of the site to fully achieve the stated goals of the mitigation plan. The Final Mitigation Plan is to be submitted with the Preconstruction Notification (PCN) Application for Nationwide permit approval of the project along with a copy of this letter. All changes made to the Final Mitigation Plan should be summarized in an errata sheet included at the beginning of the document. As it was determined that the project does not contain jurisdictional waters of the U.S., construction for the project does not require a Department of the Army permit; however, you must still provide a copy of the Final Mitigation Plan, along with a copy of this letter, to the appropriate USACE held office at least 30 days in advance of beginning construction of the project. Please note that this approval does not preclude the inclusion of permit conditions in the permit authorization for the project. Additionally, this letter provides initial approval for the Mitigation Plan, but this does not guarantee that the project will generate the requested amount of mitigation credit. As you are aware, unforeseen issues may arise during construction or monitoring of the project that may require maintenance or reconstruction that may lead to reduced credit. Thank you for your prompt attention to this matter, and if you have any questions regarding this letter, the mitigation plan review process, or the requirements of the Mitigation Rule, please call me at 919-846-2564.

We are a little confused. The last paragraph of the letter says to submit a PCN. There is no PCN needed for the project because the site is not currently jurisdictional. Do they submit a PCN anyway or was this an oversight?
