Further, summary information about the activity including administrative history of actions taken during project evaluation is attached (ORM2 Summary) and incorporated in this memorandum. 1.1 Applicant: Durham Public Schools, Mr. Bernard Hall 1.2 Activity location: 4804 and 4622 N. Roxboro Street, Durham, NC 1.3 Description of activity requiring permit: Culverting approximately 308 feet of perennial stream channel for the construction of access road to the proposed high school. 1.3.1 Proposed avoidance and minimization measures: The current site was selected after evaluating twelve sites (including the existing Durham High School location) for the construction of the new Durham High School. See attached Table. The current site was selected for various environmental and constructability reasons. Three build alternatives were investigated for the current site. The preferred alternative impacts the least amount of stream and avoids all wetland. Alternative 1 impacted 991 feet of stream and 1.8 acres of wetlands. Alternative 2 impacted 504 feet of stream and 0.6 acres of wetlands. 1.3.2 Proposed compensatory mitigation: Due to the 308 feet of permanent stream function loss due to the installation of a culvert, 618 feet of warm water stream credits will be purchased from ***. 20,038 total NRRB impact *** square feet of Neuse River riparian buffer credits will also be purchased. ** square feet of Zone 1 and ** square feet of Zone 2. ** 0.2 AC impact of City of Durham 100 foot stream buffer 1.4 Existing conditions and any applicable project history: Add Affected Environment / Environmental Consequences section of EA when completed. Page 1 of 28 CE SAW -District abbreviation (e.g. RD, O-R) (File Number, SAW 2019-01814) 1.5 Permit Authority: Section 404 of the Clean Water Act (33 USC 1344). 2.0 Scope of review for National Environmental Policy Act (i.e. scope of analysis), Section 7 of the Endangered Species Act (i.e. action area), and Section 106 of the National Historic Preservation Act (i.e. permit area) 2.1 Determination of scope of analysis for National Environmental Policy Act (NEPA): The scope of analysis includes the specific activity requiring a Department of the Army permit. Other portions of the entire project are included because the Corps does have sufficient control and responsibility to warrant federal review. Final description of scope of analysis: Access to the site from North Roxboro Road is required for the site to be feasible. The access will impact 308 feet of stream. Without the stream impacts, the site could not be constructed. 2.2 Determination of the "Corps action area" for Section 7 of the Endangered Species Act (ESA): The Corps action area is the entire area that will be impacted by construction activities (limits of disturbance). The limits of disturbance (LOD) was selected as the action area because the site could not be developed without the stream impacts. The site development is dependent on the stream impacts. 2.3 Determination of permit area for Section 106 of the National Historic Preservation Act (NHPA): The permit area includes those areas comprising waters of the United States that will be directly affected by the proposed work or structures , as well as activities outside of waters of the U.S. because all three tests identified in 33 CFR 325, Appendix C(g)(1) have been met. Final description of the permit area: The final permit area is the entire area that will be impacted by construction activities (limits of disturbance). The limits of disturbance (LOD) was selected as the permit area because the site could not be developed without the stream impacts. The site development is dependent on the stream impacts. 3.0 Purpose and Need 3.1 Purpose and need for the project as provided by the applicant and reviewed by the Corps: The purpose of the proposed project is to construct a new high school to replace the existing high school, which is in need of significant repairs with a new facility that meets the Durham Public School (DPS) high school program as Page 2 of 28 CE SAW -District abbreviation (e.g. RD, O-R) (File Number, SAW 2019-01814) well as future student capacity needs. 3.2 Basic project purpose, as determined by the Corps: Select N/A or basic purpose here. 3.3 Water dependency determination: The activity does require access or proximity to or siting within a special aquatic site to fulfill its basic purpose. Therefore, the activity is water dependent. Stream impacts result from construction of the access road. The stream impacts are unavoidable and necessary in order to meet public safety standards under the City of Durham and NCDOT code and design requirements which require the high school access road from N. Roxboro Street to align with Wellington Drive. 3.4 Overall project purpose, as determined by the Corps: Describe here. 4.0 Coordination 4.1 The results of coordinating the proposal on Public Notice (PN) are identified below, including a summary of issues raised, any applicant response and the Corps' evaluation of concerns.

Select Yes or No If yes, provide discussion: Select N/A or provide discussion as appropriate. 5.0 Alternatives Analysis (33 CFR Part 325 Appendix B(7), 40 CFR 230.5(c) and 40 CFR 1502.14). An evaluation of alternatives is required under NEPA for all jurisdictional activities. An evaluation of alternatives is required under the Section 404(b) (1) Guidelines for projects that include the discharge of dredged or fill material. NEPA requires discussion of a reasonable range of alternatives, including the no action alternative, and the effects of those alternatives; under the Guidelines, practicability of alternatives is taken into consideration and no alternative may be permitted if there is a less environmentally damaging practicable alternative. 5.1 Site selection/screening criteria: In order to be practicable, an alternative must be available, achieve the overall project purpose (as defined by the Corps), and be feasible when considering cost, logistics and existing technology. Criteria for evaluating alternatives as evaluated and determined by the Corps: Uescnae evaluation cntena nel, 5.2 Description of alternatives 5.2.1 No action alternative: The option to leave the school where it is without building a new school or associated facilities was not evaluated in detail. It was determined that the existing location of the school is inadequate due to soil conditions and space constraints, and that without expanding the current school building and facilities, the goals of the school program cannot be reached. 5.2.2 Off -site alternatives Page 4 of 28 CE SAW -District abbreviation (e.g. RD, O-R) (File Number, SAW 2019-01814) Off -site alternative 1: Numerous sites were evaluated and rejected for various reason. The attached table presents the results of the off -site evaluations. Off -site alternative 2: Description of off -site alternative 2 5.2.3 On -site alternatives On -site alternative 1 (applicant's preferred alternative): on -site alternative 3 is the Preferred Alternative for the purpose of this document. On -site alternative 1: In this alternative, the entirety of the high school program would be located between the two stream and wetland systems on the property. This would reduce the development footprint with the goal of reducing site development costs associated with the grading of the rocky area on the northwest side of the property. Access to the site would be provided at two drives along the proposed Hebron Road extension. The loading/unloading area for students from both bus and parent vehicles would be located centrally at the main entrance to the building. Student parking would be located west of the main building. Staff parking would be at the front of the building along the Hebron Road extension and west of the main entrance. Student and staff parking would be located and designed so that they would not interfere with loading/unloading operations. The competition and recreational fields would be located on the north portion of the site. The track, football field and possible future stadium would be located east of the building. These fields would be located in close proximity to the building allowing for ease of daily use by the students. The drive provided around the building would act as a fire lane which could be gated at both ends to allow for safe pedestrian use as necessary. Closing the gates would eliminate pedestrian vehicular conflict as pedestrians would have vehicular -free access to these areas. On -Site Alternative 1 would result in the placement of stormwater control measures in Waters of the U.S. and regulated riparian buffers. On -Site Alternative 1 would also result in significant impacts to the large wetland complex as well as the perennial stream located along the western boundary of the property. This would cause considerable loss of hydrological, chemical and biological connectivity to downstream waters. On -site alternative 2: ): In this alternative, the majority of the high school program is located between the two perennial streams and associated riparian buffers on the property. Similar to the On -Site Alternative 1, the primary school building would be located between the two stream and wetland systems on the property site. Athletic facilities such as the football field/stadium and competition field, however, would be sited west of the perennial stream located in the central portion of the property. Access to the site would be provided by two drives along the proposed Hebron Road extension. The loading/unloading areas for students Page 5 of 28 CE SAW -District abbreviation (e.g. RD, O-R) (File Number, SAW 2019-01814) from both bus and parent vehicles would be located centrally at the main entrance to the building. Student and staff parking would be located to the west of the main building and would not interfere with loading/unloading operations. The rear of the building would open to green, athletic field, and recreation space. This would eliminate conflict between pedestrians and vehicles as pedestrians would not have to cross a drive to obtain access to these areas. On -Site Alternative 2 would result in considerably less impacts to the large wetland and stream complex on the eastern boundary of the property. In addition, this proposed Alternative more closely resembles the ingress and egress requirements for the school. However, On -Site Alternative 2 would also result in the placement of stormwater control measures in regulated riparian buffers. The orientation of the buildings in this alternative was also predicted to impact stormwater features on the site. On -site alternative 3 (applicant's preferred alternative): This alternative follows a very similar configuration as on -site alternative 2, with the majority of the high school program located between the two stream buffers. The football field/stadium would be located on the west side of the stream buffer, and the primary building would be located on the east side of the site. Having the football field and stadium on the west side of the property was most practical, as fields will require less grading than a building. Access to the site would be provided by one drive along the access road to eventually be the Hebron Road extension with a bridge over the stream from N. Roxboro Street. A second point of access would be located off North Roxboro Street, 600 feet north of the first access drive. A third access drive from Old Well Street at the north of the site would allow access for bus staff only. Parking lot configuration in this option would be the same as in on -site alternative 2. The main difference is in the configuration of the tennis fields and baseball diamonds to allow for the multi -purpose field to be located further west in avoidance of the river buffers on the east side of the site. Similarly, the orientation of the stadium and competition field on the west side of the site are shifted slightly from alternative 2, to avoid buffer impacts. As per requested by the City, the site plan includes a 70-foot wide land reservation for future right-of-way shall the Hebron Road extension ever be constructed. This 70-foot land reservation would allow for a 3-lane road with bike lanes and sidewalks on both sides of the road as required for minor thoroughfares in the City of Durham. A 30-foot wide private drive is being proposed for school use only, specifically the staff and parent ingress/egress. 5.3 Evaluate alternatives and whether or not each is practicable under the Guidelines or reasonable under NEPA Based on the decision not to construct the Hebron Road Extension in addition to the significant proposed impacts to Waters of the U.S., regulated riparian stream buffers and downstream water Page 6 of 28 CE SAW- )istrict abbreviation (e.g. RD, O-R) (File Number, SAW 2019-01814) quality/connectivity that would result from the construction of On -Site Alternative 1, this alternative was determined not to be feasible or practical. Based on the decision not to construct the Hebron Road Extension in addition to the significant proposed impacts to regulated riparian stream buffers and downstream water quality that would result from the construction of On -Site Alternative 2, this alternative was determined not to be feasible or practical. 5.4 Least environmentally damaging practicable alternative under the 404(b)(1) Guidelines (if applicable) and the environmentally preferable alternative under N E PA: Despite impacts projected to streams, wetlands and river buffers associated with the stream crossing in on -site Alternative 3, it was determined that these impacts are unavoidable and necessary in order to meet public safety standards under the City of Durham and NCDOT code and design requirements. Despite impacts requiring an IP, on -site Alternative 3 avoided stormwater feature impacts that on - site Alternative 2 would not, avoided extensive grading that would be required if a building was located on the northwest side of the site (as in Alternative 2), and avoided stream impacts that Alternative 1 would have involved. On -Site Alternative 3 was carried forward as the preferred alternative as it was determined to be the Least Environmentally Damaging Practicable Alternative (LEDPA) and was used in further field investigations conducted as part of the Phase 1 ESA by SEPI, Inc. 6.0 Evaluation for Compliance with the Section 404(b)(1) Guidelines. The following sequence of evaluation is consistent with 40 CFR 230.5 6.1 Practicable alternatives to the proposed discharge consistent with 40 CFR 230.5(c) are evaluated in Section 5. The statements below summarize the analysis of alternatives. In summary, based on the analysis in Section 5.0 above, the no -action alternative, which would not involve discharge into waters, is not practicable. For those projects that would discharge into a special aquatic site and are not water dependent, the applicant has demonstrated there are no practicable alternatives that do not involve special aquatic sites. It has been determined that there are no alternatives to the proposed discharge that would be less environmentally damaging. (Subpart B, 40 CFR 230.10(a)). The proposed discharge in this evaluation is the practicable alternative with the least adverse impact on the aquatic ecosystem, and it does not have other significant environmental consequences.

Each disposal site shall be specified through the application of these Guidelines: Discussion: 6.3 Potential impacts on physical and chemical characteristics of the aquatic ecosystem (Subpart C 40 CFR 230.20). See Table 1: Table 1 — Potential Impacts on Physical and Chemical Characteristics Minor Minor Physical and No Negligible Effect Effect Major Chemical N/A Effect Effect (Short (Long Effect Characteristics Term) Term) Substrate X Suspended X particulates/ turbidity Water X Current patterns and X water circulation Normal water X fluctuations Salinity gradients X Discussion: There will be a minor short-term effect to stream substrates during construction of the culverts. The effect is considered minor and short term because the culverts will be buried per NCDEQ requirements. An erosion and sediment control plan will be developed and implemented to avoid effects from suspended particles/turbidity, water, current patterns and water circulation and normal water fluctuations. There are no salt water features located on the project site. 6.4 Potential impacts on the living communities or human uses (Subparts D, E and F): 6.4.1 Potential impacts on the biological characteristics of the aquatic ecosystem (Subpart D 40 CFR 230.30). See Table 2: Page 8 of 28 CE SAW -District abbreviation (e.g. RD, O-R) (File Number, SAW 2019-01814) Table 2 — Potential Impacts on Biological Characteristics Minor Minor Biological No Negligible Effect Effect Major NSA characteristics Effect Effect (Short (Long Effect Term) Term) Threatened and X endangered species Fish, crustaceans, mollusk, and other X aquatic organisms Other wildlife X Discussion: Federallv protected species listed for Durham Countv.

Large dominant trees are utilized for nesting sites, typically within 1.0 mile of open water. Bodies of water typically need to be at least 2 acres or larger to be able to support a bald eagle population. A desktop-GIS assessment of the project study area, as well as the area within a 1 mile radius of the project limits, was performed on May 31, 2019, using 2010 color aerials. The Eno River is the only water body large enough to Page 9 of 28 CE SAW- )istrict abbreviation (e.g. RD, O-R) (File Number, SAW 2019-01814) support foraging habitat within one mile of the project study area and is 0.5 miles north of the project study area, and Falls Lake is located 5 miles to the east. The bald eagle survey area designated by U.S. Fish and Wildlife is a 660-foot buffer around the project study area. Land use within and in the 660 feet surrounding the project study area is highly urbanized and does not contain water bodies large enough to support bald eagle habitat. Additionally, a review of the NCNHP database on May 31, 2019, revealed no known occurrences of this species within one mile of the project study area. Due to the lack of habitat, known occurrences, and minimal impact anticipated for this project, it has been determined that this project will not affect this species. Biological Conclusion: No Effect Carolina madtom Biological Conclusion: No Effect The Carolina madtom prefers shallow sand-, gravel-, and detritus -bottomed riffles and runs with little or no current over fine to coarse sand bottom in small to medium rivers. North Carolina Natural Heritage Program (NCNHP) records generated on May 23, 2019 document no occurrences of Carolina madtom within one mile of the project study area. Streams were assessed in study area on June 12, 2019. No suitable habitat was observed during surveys. Streams were determined to be severely unstable and eroding. Critical Habitat Carolina madtom Biological Conclusion: No Effect USFWS has proposed critical habitat for the Neuse River waterdog within Durham County. The nearest proposed critical habitat is the Eno River approximately 3/4 mile downstream of the study area. Neuse River waterdog Biological Conclusion: No Effect The Neuse River waterdog inhabits well oxygenated medium to large rivers and streams with high water quality. They prefer eddies and backwaters with large amounts of leaves and woody debris. NCNHP records generated on May 23, 2019 document no occurrences of Neuse River waterdog within one mile of the project study area. Streams were assessed in study area on June 12, 2019. No suitable habitat was observed during surveys. Streams were determined to be severely unstable and eroding. Critical Habitat Neuse River waterdog Biological Conclusion: No Effect USFWS has proposed critical habitat for the Neuse River waterdog within Durham County. The nearest proposed critical habitat is the Eno River approximately 3/4 mile downstream of the study area. Page 10 of 28 CE SAW- )istrict abbreviation (e.g. RD, O-R) (File Number, SAW 2019-01814) Atlantic pigtoe Biological Conclusion: No Effect The Atlantic pigtoe requires fast flowing, well oxygenated high quality riverine/large creek and is restricted to fairly pristine habitats. It is typically found in headwaters or rural watersheds. The preferred habitat of the Atlantic pigtoe is coarse sand and gravel at the downstream edge of riffles. NCNHP records generated on May 23, 2019 document no occurrences of Atlantic pigtoe within one mile of the project study area. Streams were assessed in study area on June 12, 2019. No suitable habitat was observed during surveys. Streams were determined to be severely unstable and eroding. Critical Habitat Atlantic pigtoe Biological Conclusion: No Effect USFWS has proposed critical habitat for the Atlantic pigtoe within Durham County. The nearest proposed critical habitat is the Eno River approximately 3/4 mile downstream of the study area. Dwarf wedgemussel Biological Conclusion: No Effect In North Carolina, the dwarf wedgemussel is known from the Neuse and Tar River drainages. The mussel inhabits creek and river areas with a slow to moderate current and sand, gravel, or firm silt bottoms. Water in these areas must be well oxygenated. Stream banks in these areas are generally stable with extensive root systems holding soils in place. NCNHP records generated on May 23, 2019 document no occurrences of dwarf wedgemussel within one mile of the project study area. Streams were assessed in study area on June 12, 2019. No suitable habitat was observed during surveys. Streams were determined to be severely unstable and eroding. Michaux's sumac Habitat Description: Michaux's sumac most commonly grows in highway rights - of way, roadsides, or on the edges of artificially maintained clearings. NCNHP records generated on May 23, 2019 document no occurrences of Michaux's sumac within one mile of the project study area. Suitable habitat consisting of maintain rights -of way were surveyed on May 21, 2019 and no individuals were found. Biological Conclusion: No Effect Smooth coneflower Habitat Description: Optimal habitat for the smooth coneflower consists of periodically disturbed woods/roadside areas with abundant sunlight available. Habitat for smooth coneflower does exist within the project study area. NCNHP Page 11 of 28 CE SAW -District abbreviation (e.g. RD, O-R) (File Number, SAW 2019-01814) records generated on May 23, 2018 documented an occurrence of the smooth coneflower within 1 mile of the project study area. Surveys for smooth coneflower were performed within the study area on May 21, 2019 and no individuals were found. Biological Conclusion: May Affect — Not Likely to Adversely Affect There will be a minor short-term effect to fish, crustaceans, mollusk, other aquatic organisms and other wildlife during construction of the culverts and other construction activities. The effect is considered minor and short term because the culverts will be buried per NCDEQ requirements. 6.4.2 Potential impacts on special aquatic sites (Subpart E 40 CFR 230.40). See Table 3: Table 3 — Potential Impacts on Special Aquatic Sites Minor Minor No Negligible Effect Effect Major Special Aquatic Sites N/A Effect Effect (Short (Long Effect Term) Term) Sanctuaries and X refuges Wetlands X Mud flats X Vegetated shallows X Coral reefs X Riffle and Pool X Complexes Discussion: There are no aquatic sanctuaries, refuges, mud flats, vegetated shallows or coral reefs within the study area. The preferred alternative will avoid all wetland impacts. There will be a minor short-term effect to riffle and pool complexes during construction of the culverts. The effect is considered minor and short term because the effect will occur only during construction and the culverts will be buried per NCDEQ requirements. 6.4.3 Potential impacts on human use characteristics (Subpart F 40 CFR 230.50). See Table 4: Page 12 of 28 CE SAW -District abbreviation (e.g. RD, O-R) (File Number, SAW 2019-01814) Table 4 — Potential Impacts on Human Use Characteristics Minor Minor Human Use No Negligible Effect Effect Major N/A Characteristics Effect Effect (Short (Long Effect Term) Term) Municipal and private X water supplies Recreational and X commercial fisheries Water -related X recreation Aesthetics X Parks, national and historical monuments, national seashores, X wilderness areas, research sites, and similar preserves Discussion: The current properties are private residential properties. There are no municipal and private water supplies, recreational and commercial fisheries, water -related recreation, aesthetics, parks, national and historical monuments, national seashores, wilderness areas, research sites, and similar preserves located on the property. 6.5 Pre -testing evaluation (Subpart G, 40 CFR 230.60): The following has been considered in evaluating the biological availability of possible contaminants in dredged or fill material. See Table 5: Table 5 — Possible Contaminants in Dredged/Fill Material Physical characteristics X Hydrography in relation to known or anticipated sources of contaminants X Results from previous testing of the material or similar material in the X vicinity of the project Known, significant sources of persistent pesticides from land runoff or X percolation Spill records for petroleum products or designated (Section 331 of CWA) X hazardous substances Other public records or significant introduction of contaminants from X industries, municipalities, or other sources Page 13 of 28 CE SAW- )istrict abbreviation (e.g. RD, O-R) (File Number, SAW 2019-01814) Table 5 — Possible Contaminants in Dredged/Fill Material Known existence of substantial material deposits of substances which could be released in harmful quantities to the aquatic environment by X man -induced discharge activities Discussion: SEPI, Inc. conducted a Phase I ESA for the property located at 4622 North Roxboro Street and 4804 North Roxboro Street (Target Property) in Durham, North Carolina. The Phase I ESA was performed in accordance with the scope and limitations as outlined in American Society of Testing and Materials (ASTM) Standard Practice Designation E 1527-13 and presented in the May 15, 2019 proposal. The assessment did not revealed evidence of RECs, HRECs, de minimis conditions, or other environmental concerns on the Target Property. It has been determined that testing is not required because the proposed material is not likely to be a carrier of contaminants because it is comprised of sand, gravel or other naturally occurring inert material. 6.6 Evaluation and testing (Subpart G, 40 CFR 230-61): Discussion: The Phase I ESA did not revealed evidence of RECs, HRECs, de minimis conditions, or other environmental concerns on the Target Property. Therefore, no testing was performed. 6.7 Actions to minimize adverse impacts (Subpart H). The following actions, as appropriate, have been taken through application of 40 CFR 230.70-230.77 to ensure minimal adverse effects of the proposed discharge. See Table 6: Table 6 — Actions to Ensure Adverse Effects are Minimized Actions concerning the location of the discharge X Actions concerning the material to be discharged X Actions controlling the material after discharge X Actions affecting the method of dispersion X Actions affecting plant and animal populations X Actions affecting human use X Discussion: The location of the discharge will be the minimum required to complete the project. As presented above several alternatives were evaluated. The preferred alternative minimizes the discharge required. All required engineering and construction practices (including erosion and sedimentation control) were and will be followed to minimize effects to plants animals and human uses. Page 14 of 28 CE SAW -District abbreviation (e.g. RD, O-R) (File Number, SAW 2019-01814) 6.8 Factual Determinations (Subpart B, 40 CFR 230.11). The following determinations are made based on the applicable information above, including actions to minimize effects and consideration for contaminants. See Table 7: Table 7 — Factual Determinations of Potential Impacts Minor Minor Site N/A No Negligible Effect Effect Major Effect Effect (Short (Long Effect Term) Term) Physical substrate X Water circulation, X fluctuation and salinity Suspended particulates/turbidity X Contaminants X Aquatic ecosystem and X organisms Proposed disposal site Cumulative effects on the aquatic ecosystem X Secondary effects on the aquatic ecosystem X Discussion: There will be a minor short term effect to suspended particulates/turbidity and aquatic ecosystem and organisms during construction of the culverts. The effect is considered minor and short term because construction will follow the approved erosion and sediment control plan and the culverts will be buried per NCDEQ requirements. There will be no effects from contaminates. The Phase 1 ESA did not identify any potential contaminants and construction activities will the approved erosion and sediment control plan. There will be no secondary effects on the aquatic ecosystem. Stormwater control measures are included in the design to control the discharge of stormwater form the completed site to the aquatic ecosystem. 6.9 Findings of compliance or non-compliance with the restrictions on discharges (40 CFR 230.10(a-d) and 230.12). Based on the information above, including the factual determinations, the proposed discharge has been evaluated to determine whether any of the restrictions on discharge would occur. See Table 8: Page 15 of 28 CE SAW- )istrict abbreviation (e.g. RD, O-R) (File Number, SAW 2019-01814) Table 8 — Compliance with Restrictions on Discharge Subject Yes No 1. Is there a practicable alternative to the proposed discharge that would be less damaging to the environment (any alternative with less aquatic resource effects, or an alternative with more aquatic X resource effects that avoids other significant adverse environmental consequences?) 2. Will the discharge cause or contribute to violations of any X applicable water quality standards? 3. Will the discharge violate any toxic effluent standards (under X Section 307 of the Act)? 4. Will the discharge jeopardize the continued existence of X endangered or threatened species or their critical habitat? 5. Will the discharge violate standards set by the Department of X Commerce to protect marine sanctuaries? 6. Will the discharge cause or contribute to significant degradation X of waters of the U.S.? 7. Have all appropriate and practicable steps (Subpart H, 40 CFR 230.70) been taken to minimize the potential adverse impacts of the X discharge on the aquatic ecosystem? Discussion: Several alternatives were evaluated. The selected preferred alternative was determined to be the Least Environmentally Damaging Practicable Alternative (LEDPA). 7.0 General Public Interest Review (33 CFR 320.4 and RGL 84-09) The decision whether to issue a permit will be based on an evaluation of the probable impacts, including cumulative impacts, of the proposed activity and its intended use on the public interest as stated at 33 CFR 320.4(a). To the extent appropriate, the public interest review below also includes consideration of additional policies as described in 33 CFR 320.4(b) through (r). The benefits which reasonably may be expected to accrue from the proposal are balanced against its reasonably foreseeable detriments. 7.1 All public interest factors have been reviewed and those that are relevant to the proposal are considered and discussed in additional detail.

The proposed activities within the Corps federal control and responsibility likely will result in a negligible release of greenhouse gases into the atmosphere when compared to global greenhouse gas emissions. Greenhouse gas emissions have been shown to contribute to climate change. Aquatic resources can be sources and/or sinks of greenhouse gases. For instance, some aquatic resources sequester carbon dioxide whereas others release methane; therefore, authorized impacts to aquatic resources can result in either an increase or decrease in atmospheric greenhouse gas. These impacts are considered de minimis and are negated through compensatory mitigation. Greenhouse gas emissions associated with the Corps federal action may also occur from the combustion of fossil fuels associated with the operation of construction equipment, increases in traffic, etc. The Corps has no authority to regulate emissions that result from the combustion of fossil fuels. These are subject to federal regulations under the Clean Air Act and/or the Corporate Average Fuel Economy (CAFE) Program. Greenhouse gas emissions from the Corps action have been weighed against national goals of energy independence, national security, and economic development and determined not contrary to the public interest. ADD, if determined appropriate, otherwise deletE The applicant Page 18 of 28 CE SAW- )istrict abbreviation (e.g. RD, O-R) (File Number, SAW 2019-01814) voluntarily provided the Corps with an analysis of greenhouse gas emissions that they produced for other local, state, and/or federal requirements, entitled [INSERT NAME], dated [Insert DATE]. The portions of that document pertaining to the actions within the Corps federal control and responsibility are incorporated by reference. 7.2 The relative extent of the public and private need for the proposed structure or work: There is a public need for the new high school. The existing high school, which is in need of significant repairs with a new facility that meets the Durham Public School (DPS) high school program as well as future student capacity needs. 7.3 If there are unresolved conflicts as to resource use, explain how the practicability of using reasonable alternative locations and methods to accomplish the objective of the proposed structure or work was considered. Discussion: There are no unresolved conflicts as to resource use. Initial public comment was solicited from the residents surrounding the project site. The comment period ended August 1, 2020. 7.4 The extent and permanence of the beneficial and/or detrimental effects that the proposed work is likely to have on the public and private use to which the area is suited: Detrimental effects are expected to be minimal and temporary. Beneficial effects are expected to be more than minimal and permanent. Detrimentai errects to public ana private uses will be minimal and temporary only associated with construction activities. Beneficial effects to public and private uses will be more than minimal and permanent. The project will result in a new state of the art public high school. 8.0 Mitigation (33 CFR 320.4(r), 33 CFR Part 332, 40 CFR 230.70-77, 40 CFR 1508.20 and 40 CFR 1502.14) 8.1 Avoidance and Minimization: When evaluating a proposal including regulated activities in waters of the United States, consideration must be given to avoiding and minimizing effects to those waters. Avoidance and minimization measures are described above in Sections 1 and 3. Page 19 of 28 CE SAW -District abbreviation (e.g. RD, O-R) (File Number, SAW 2019-01814) Were any other mitigative actions including project modifications discussed with the applicant implemented to minimize adverse project impacts?

Select Yes, No, or Nl� If yes, provide rationale for the deviation, including the likelihood for ecological success and sustainability, location of the compensation site relative to the impact site and their significance within the watershed, and/or the costs of the compensatory mitigation project (see 33 CFR §332.3(a)(1)): Select N/A or provide rationale here Page 20 of 28 CE SAW -District abbreviation (e.g. RD, O-R) (File Number, SAW 2019-01814) 8.4 Amount of compensatory mitigation: Enter amount here Rationale for required compensatory mitigation amount: Provide discussion here 8.5 For permittee responsible mitigation identified in 9.3.3 above, the final mitigation plan must include the items described in 33 CFR 332.4(c)(2) through (c)(14) at a level of detail commensurate with the scale and scope of the impacts. As an alternative, the district engineer may determine that it would be more appropriate to address any of the items described in (c)(2) through (c)(14) as permit conditions, instead of components of a compensatory mitigation plan. Presence of sufficient information related to each of these requirements in the applicant's mitigation plan is indicated by "Yes" in Table 11. "No" indicates absence or insufficient information in the plan, in which case, additional rationale must be provided below on how these requirements will be addressed through special conditions or why a special condition is not required: Table 11 — Perm ittee-Responsible Mitigation Plan Requirements Requirement Yes No Objectives Site selection Site protection instrument Baseline information Determination of credits Mitigation work plan Maintenance plan Performance standards Monitoring requirements Long-term management plan Adaptive management plan Financial assurances Other For any "No", provide rationale on how the subject component(s) of the compentatory mitigation plan will be addressed as special conditions or why no special conditions are required: Provide discussion her 9.0 Consideration of Cumulative Impacts (40 CFR 230.11(g) and 40 CFR 1508.7, RGL 84-9) Cumulative impact is the impact on the environment which results from the incremental impact of the action when added to other past, present, and reasonably foreseeable future actions regardless of what agency (Federal or non -Federal) or person undertakes such other actions. Cumulative impacts can result from individually minor direct and indirect but collectively significant actions taking place over a Page 21 of 28 CE SAW- )istrict abbreviation (e.g. RD, O-R) (File Number, SAW 2019-01814) period of time. A cumulative effects assessment should consider how the direct and indirect environmental effects caused by the proposed activity requiring DA authorization (i.e., the incremental impact of the action) contribute to cumulative effects, and whether that incremental contribution is significant or not. . 9.1 Identify/describe the direct and indirect effects caused by the proposed activity: A review of potential cumulative impacts to Waters of the U.S. from the construction of the Proposed Northern High School, indicates that the proposed development would not have significant adverse effects on the aquatic ecosystem. The rationale for this presumption is based on the following considerations: • All stormwater devices will be located outside of jurisdictional streams and wetlands and protected stream buffers. • The proposed stormwater management systems, including numerous stormwater treatment and retainage structures, are planned to capture and treat all stormwater on -site before discharge to surface waters. • Adequate Erosion & Sediment Control systems will be in place and maintained during construction. • No untreated stormwater or construction runoff will be discharged into Waters of the U.S. (wetlands and streams); therefore, the water quality of downstream receiving waters, specifically the Eno River, will not be impaired. The proposed impacts to the Waters of the U.S. from construction of the proposed Northern High School should have no cumulative effects on the quality of other jurisdictional waters occurring beyond the Preferred Alternative Site. This presumption is based on the review of environmental documentation regarding known current and past federal and non-federal actions in the area. Projects in the planning phase were also considered, including reasonably foreseeable (rather than speculative) actions that have the potential to interact with the proposed action. To have reasonable assurances that there would be cumulative effects to projects when considered together or incrementally, the projects needed to occur within similar time frames and within a geographic area, coinciding with the proposed action. 9.2 The geographic scope for the cumulative effects assessment is: Describe here. 9.3 The temporal scope of this assessment covers: Describe here. 9.4 Describe the affected environment: Describe here. 9.5 Determine the environmental consequences: )escribe here. Page 22 of 28 CE SAW- )istrict abbreviation (e.g. RD, O-R) (File Number, SAW 2019-01814) 9.6 Discuss any mitigation to avoid, minimize or compensate for cumulative effects: Provide discussion here. 9.7 Conclusions regarding cumulative impacts: When considering the overall impacts that will result from the proposed activity, in relation to the overall impacts from past, present, and reasonably foreseeable future activities, the incremental contribution of the proposed activity to cumulative impacts in the area described in section 9.2, are not considered to be significant . Compensatory mitigation will be required to help offset the impacts to eliminate or minimize the proposed activity's incremental contribution to cumulative effects within the geographic area described in Section 9.2. Mitigation required for the proposed activity is discussed in Section 8.0. 10.0 Compliance with Other Laws, Policies, and Requirements 10.1 Section 7(a)(2) of the Endangered Species Act (ESA): Refer to Section 2.2 for description of the Corps action area for Section 7. 10.1.1 Has another federal agency been identified as the lead agency for complying with Section 7 of the ESA with the Corps designated as a cooperating agency and has that consultation been completed?
