4a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application:*
The study area consists primarily of undeveloped mixed pine/hardwood forest, maintained/disturbed scrub -shrub and some small meadow areas. Adjacent to the study area is the
Palisades Elementary School to the west, residential development to the south, McDowell Nature Preserve to the north and undeveloped forest to the southwest and east. The
Palisades Elementary School was constructed under NWP #39 (SAW-2009-00380) issued in March 2012. The permit for the Palisades Elementary School authorized 424 If of stream
impact (209 If determined to be intermittent/unimportant aquatic function), 70 If of temporary stream impact to Stream A associated with utility placement, and 0.075 acre of wetland
impact. During construction of the Palisades Elementary School erosive velocities were encountered in the location of the authorized temporary stream impact. CMS consulted with the
state and was instructed to place riprap in the stream to combat the erosion. This action was not authorized by the Corps and constitutes a permanent unauthorized impact. CMS
brought this unauthorized impact to the attention of the Corps during the wetland boundary field review. The "after -the -fact" portion of this permit application pursues authorization for
the 70 If of permanent impact to Stream A. CMS intends to remove the riprap from Stream A and restore this reach of stream to natural conditions as a condition of the after -the -fact
permit authorization. This permit application is also requesting 35 If of permanent impact to Intermittent Stream E, 0.022 acre of permanent impact to Wetland A, and.017 acre of
temporary impact to Wetland A. It's important to note that with the exception of a shared entrance from NC 49 the high school and elementary school function independently of each
other with separate infrastructure, parking, utilities, and stormwater management facilities.

4b. Have Corps permits or DWR certifications been obtained for this project (including all prior phases) in the past?*
r Yes r No r Unknown
4c. If yes, please give the DWR Certification number or the Corps Action ID (exp. SAW-0000-00000).

4h. Explain the purpose of the proposed project:*
The Olympic Relief High School project is intended to provide additional classroom facilities for the students within the Charlotte -Mecklenburg School system, and specifically intended
to reduce the burden on the existing Olympic High School located on Sandy Porter Road in Charlotte. The Wetland Disturbance Overall Site Plan is attached as Figure WD-1. The
project will also include the restoration of 70 If of Stream A. This portion of Stream A was previously authorized to be temporarily impacted for utility line placement during the
construction of the adjacent Palisades Elementary School. The unauthorized placement of riprap in Stream A, Which constitutes a permanent impact, is the subject of the "after -the -fact"
permit portion of this application. CMS intends to mitigate the unauthorized impact by removing the riprap and restoring 70 If of Stream A to natural conditions.
41. Describe the overall project in detail, including indirect impacts and the type of equipment to be used:*
The restoration of 70 If of Stream A is proposed to be completed prior to the construction of the Olympic Relief High School (See Figure WD-4, and Bulletin Drawings 1, 2, and 3 of 3 of
the Stream Restoration Plan). The goal of the stream restoration is to remove the unauthorized placement of riprap that occurred during the construction of the Palisades Park
Elementary School. Additional details on proposed impacts and the stream restoration plan are discussed in the Supplemental Information attached under Miscellaneous. The intent is
to start construction of the high school with the implementation of the perimeter controls for the approved erosion and sedimentation control plan. Once the stream restoration is
complete, then the grading for the high school Would commence using bulldozers, and other grading and construction equipment. Impacts to Wetland A will result from the grading
required for the school access drive as depicted on Figure WD-2. The proposed storm water management plan is based on the utilization of a collection system, comprised of storm
water inlets and collection piping. The collection system is connected to a wet pond at the southwestern corner of the high school site. The wet pond is designed to detain and treat the
storm water runoff from the high school campus.

Permanent fill impacts of 35 If Will result from the stormwater basin pipe outlet protection riprap apron at Intermittent Stream E (See Figures WD-3 and
WD-6). Intermittent Stream E is rated Medium according to INC SAM (NC SAM Form is attached under Miscellaneous) and will require a waiver based
on previously permitted impacts. The proposed 70 If of Stream A restoration is proposed to mitigate the unauthorized permanent impact to the stream
which is covered by the "after -the -fact" permit portion of this application.
E. Impact Justification and Mitigation U
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
The original development master plan included two road connectors through the proposed high school site, connecting the Palisades residential
development to York Road (Hwy 49) which would have required multiple crossings of Perennial Stream B. It was determined these road connections
will not be required based on an earlier agreement with the residential neighborhood developer and CMS objections. Based on CMS's assessment, a
future maintenance crossing of the restored reach of Intermittent Stream A is not required due to accessibility to the eAsting sanitary system/easement
from either side of the intermittent stream. The embankment fill slopes from the proposed tennis courts were designed at a steeper 2:1 ratio to avoid
impacts to Intermittent Stream D. The high school access road, campus and facilities were oriented in a manner that avoided jurisdictional areas to the
maximum extent practicable.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
Measures used to avoid and minimize impacts include: using orange safety fencing to establish the construction limits and preventing unauthorized
access to jurisdictional areas; using a single construction access point; hand clearing wetland vegetation where feasible; using minimally sized
construction equipment; and minimizing the amount of daily earthworking disturbances.

2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State
2a. Does the project require Compensatory Mitigation for impacts to Waters of the U.S. or Waters of the State?
r Yes r No

4e. Riparian wetland mitigation requested:
(acres)
4g. Coastal (tidal) wetland mitigation requested:
(acres)
4h. Comments
The 35 If of proposed impact to Intermittent Stream E will be mitigated by the purchase of 70 If of In -Lieu fee credits from the Charlotte -Mecklenburg
Storm Water Services Umbrella Bank. Permanent wetland impact totals, even when considered cumulatively with the previous elementary school
impacts, are less than 0.1 acre, so no wetland mitigation is proposed.
F. Stormwater Management and Diffuse Flow Plan (required by DWR)
1. Diffuse Flow Plan
1a. Does the project include or is it adjacent to protected riparian buffers identified within one of the NC Riparian Buffer Protection Rules?
r Yes r No
If no, explain why:
The project is not located in an area with protected riparian buffers. Only the main stem of the Catawba River is subject to NC Riparian Buffer Protection Rules.
2. Stormwater Management Plan
2a. Is this a NCDOT project subject to compliance with NCDOT's Individual NPDES permit NCS000250?*
r Yes r No
2b. Does this project meet the requirements for low density projects as defined in 15ANCAC 02H .1003(2)?
r Yes r No

SUBJECT: WATER AND SEWER FLOW ACCEPTANCE
CMS NEW HS OLYMPIC RELIEF (17)
15221 YORK ROAD, CHARLOTTE, NC
CLTWATER TRACKING# 20195473

After an analysis of the sanitary sewer associated with the proposed design of project, 20195473,
CMS NEW HS OLYMPIC RELIEF (17), it was determined that there is sufficient capacity to
accommodate the proposed sewer flow of 44,400 gallons per day (240 persons x 10 gpd/person;
2,500 students x 15 gpd/student) at the connection point(s) indicated on the submitted utility plan
for transmission to the McAlpine Creek Wastewater Treatment Plant; NPDES permit number
NC0024970, for treatment. This acceptance of flow is based upon the existing capacity of the
designated publicly owned treatments works. Please see attached NCDEQ-FTSE form.

Charlotte Water (CLTWater) agrees to furnish water to the subject project. The water quality to the
subject project is regulated by the State Drinking Water Act Amendments of 1986 and The Water
Supply Management Plan, PWS ID # 0160010 on file with the Public Water Supply Section of
NCDEQ. However, CLTWater cannot guarantee a constant pressure or quality of flow.

The applicant should understand that due to the involvement of other agencies and continuing
growth of the water system, the ability to provide service for future projects cannot be guaranteed
nor reserved. Connection to the CLTWater system is accepted on a first come, first served basis.

The applicant should understand that this letter is not authorization to construct or extend private
water or sewer systems, as the appropriate local or State permits are required prior to construction.
If the appropriate authorization to construct permits are not obtained construction has not started
within two (2) years of issuance of this flow acceptance, and payment for any service connections
have not been received within two (2) years of issuance of this flow acceptance letter, this flow
acceptance approval shall be rescinded, and a new flow acceptance request must be made.
The CAP analysis performed determines available capacity within the existing public gravity sewer
system. The developer is responsible for any additional private or public sewer infrastructure
required to convey flow from the proposed development to the existing public gravity sewer.

If you have any questions, please do not hesitate to contact me at [phone].

Sincerely,

Guillermo Anzola

Dear Mr. Phillips:

Subject: Olympic Relief High School; Mecklenburg County, North Carolina
Log No. 4-2-19-245

The U.S. Fish and Wildlife Service (Service) has reviewed the information provided in your
correspondence dated May 31, 2019. We submit the following comments in accordance with the
provisions of the Fish and Wildlife Coordination Act, as amended (16 U.S.C. 661-667e); the
National Environmental Policy Act (42 U.S.C. §4321 et seq.); and section 7 of the Endangered
Species Act of 1973, as amended (16 U.S.C. 1531-1543) (Act).

Project Description
According to the information provided, the proposed project would consist of a new high school
on 116 acres of primarily wooded land near Charlotte, North Carolina. The site contains an
existing elementary school and is adjacent to McDowell Nature Preserve. The site contains
forested and cleared areas, access roads, and transitional edge habitats. Several unnamed
tributaries to Studman Branch and Lake Wylie occur onsite.

Federally Listed Endangered and Threatened Species
Service records indicate multiple mist net captures for the federally threatened northern long-
eared bat (Myotis septentrionalis) in the proposed project vicinity. Suitable summer roosting
habitat may be present in the project area for this animal. However, the final 4(d) rule (effective
as of February 16, 2016), exempts incidental take of northern long-eared bat associated with
activities that occur greater than 0.25 miles from a known hibernation site, and greater than 150
feet from a known, occupied maternity roost during the pup season (June 1 – July 31). Based on
the information provided, the project (which may or may not require tree clearing) would occur
at a location where any incidental take that may result from associated activities is exempt under
the 4(d) rule. Although not required, we encourage you to avoid any associated tree
clearing activities during this animal’s maternity roosting season from May 15 – August 15.

Based on the information provided, suitable habitats for several federally protected plant species
may occur onsite. The federally endangered Schweinitz’s sunflower (Helianthus schweinitzii),
2

smooth coneflower (Echinacea laevigata), and Michaux’s sumac (Rhus michauxii) occur in
similar habitat conditions which may include roadsides, utility line rights of way, forest
openings, forest edges, and old pastures. Service records indicate nearby occurrences of one or
more of these species. We request that a qualified biologist survey for these species where
project-mediated impacts overlap suitable habitats. A survey conducted from late August –
October (or first frost) would be within the optimal survey window for all three of these species.
Survey results should be submitted to this office for review prior to any construction activities.

Please be aware that in accordance with the Act, it is the responsibility of the appropriate federal
agency or its designated representative to review its activities or programs and to identify any
such activities or programs that may affect endangered or threatened species or their habitats. If
it is determined that the proposed activity may adversely affect any species federally listed as
endangered or threatened, formal consultation with this office must be initiated.

Bald Eagle
The project area lies within the range of the bald eagle (Haliaeetus leucocephalus) and suitable
nesting trees may be present onsite. We request that onsite surveys also document occurrences
of this species and any specifically any evidence of bald eagle nests. If any active nests are
located onsite, we request that work at the site be restricted from mid-January through July in
order to prevent adverse impacts to the bald eagle. This will prevent disturbance of the eagles
from the egg-laying period until the young fledge, which encompasses their most vulnerable
times. We ask that you consult with this office before construction begins to confirm that the
eagles have left the nest. Once this has been confirmed, construction may begin.

The bald eagle has been removed from the federal list of endangered and threatened species due
to its recovery. However, this species is protected by the Bald and Golden Eagle Protection Act
(16 U.S.C. 668-668d) and the Migratory Bird Treaty Act (16 U.S.C. 703-712). The Bald and
Golden Eagle Protection Act, enacted in 1940, and amended several times, prohibits anyone
without a permit issued by the Secretary of the Interior from “taking” bald eagles, including their
parts, nests, or eggs. “Take” is defined as to “pursue, shoot, shoot at, poison, wound, kill,
capture, trap, collect, molest or disturb.” “Disturb” means “To agitate or bother a bald or
golden eagle to the degree that interferes with or interrupts normal breeding, feeding, or
sheltering habits, causing injury, death, or nest abandonment.” In addition to immediate
impacts, these definitions also cover impacts that result from human-induced alterations initiated
around a previously used nest site during a time when eagles are not present if, upon an eagle’s
return, such alterations agitate or bother the eagle to a degree that interferes with or interrupts
normal breeding, feeding, or sheltering habits and causes injury, death, or nest abandonment.

We offer the following recommendations on behalf of natural resources:

Erosion and Sediment Control
Measures to control sediment and erosion should be installed before any ground-disturbing
activities occur. To the extent that is practical, any associated instream work should occur under
dry conditions utilizing a temporary diversion/pump-around system or other impact minimization
methods. Grading and backfilling should be minimized, and existing native vegetation should be
retained (if possible) to maintain riparian cover for fish and wildlife. Disturbed areas should be
3

revegetated with native grass and tree species as soon as the project is completed. Ground
disturbance should be limited to what will be stabilized quickly, preferably by the end of the
workday. Natural fiber matting (coir) should be used for erosion control as synthetic
netting can trap animals and persist in the environment beyond its intended purpose.

Riparian Buffers
Natural, forested riparian buffers are critical to the health of aquatic ecosystems. They
accomplish the following:

1. catch and filter runoff, thereby helping to prevent nonpoint-source pollutants
from reaching streams;
2. enhance the in-stream processing of both point- and nonpoint-source
pollutants;
3. act as “sponges” by absorbing runoff (which reduces the severity of floods)
and by allowing runoff to infiltrate and recharge groundwater levels (which
maintains stream flows during dry periods);
4. catch and help prevent excess woody debris from entering the stream and
creating logjams;
5. stabilize stream banks and maintain natural channel morphology;
6. provide coarse woody debris for habitat structure and most of the dissolved
organic carbon and other nutrients necessary for the aquatic food web; and
7. maintain air and water temperatures around the stream.

Forested riparian buffers (a minimum 50 feet wide along intermittent streams and 100 feet wide
along perennial streams [or the full extent of the 100-year floodplain, whichever is greater])
should be created and/or maintained along all aquatic areas. Impervious surfaces, ditches, pipes,
roads, utility lines (sewer, water, gas, transmission, etc.), and other infrastructures that require
maintained, cleared rights-of-way and/or compromise the functions and values of the forested
buffers should not occur within these riparian areas.

Road Crossings
We encourage you to consider the use of bridges or spanning structures for all permanent
roadway crossings of streams and associated wetlands. Structures should span the channel and
the floodplain in order to minimize impacts to aquatic resources, allow for the movement of
aquatic and terrestrial organisms, and eliminate the need to place fill in streams and floodplains.

If bridges are not possible and culverts are the only option, we suggest using bottomless culverts.
Bottomless culverts preserve the natural stream substrate, create less disturbance during
construction and provide a more natural post-construction channel. Culverts should be
sufficiently sized to mimic natural stream functions and habitats located at the crossing site;
allow for water depth, volume (flow), and velocity levels that will permit aquatic organism
passage; and accommodate the movement of debris and bed material during bank-full events.

In the event that a traditional culvert is the only option, the culvert design should provide for a
minimum water depth in the structure during low-flow/dry periods. Sufficient water depth
should be maintained in all flow regimes so as to accommodate both the upstream and
4

downstream movement of aquatic species. Water depth inside the culvert must be adequate for
fish to be completely immersed and all other aquatic life to move freely. The culvert should be
designed and installed at the same slope as the stream grade to maintain an acceptable water
velocity for aquatic life passage and for stream substrate characteristics to be retained within the
culvert.

Where feasible, we recommend the use of multiple barrels, in addition to the low-flow barrel(s),
to accommodate flood flows. Floodplain barrels should be placed on or near stream
bank-full or floodplain bench elevation and discharge onto floodplain benches. Where
appropriate, install sills on the upstream end of floodplain barrels to restrict or divert the base
stream flow to a single barrel. If the culvert is longer than 40 linear feet, alternating or notched
baffles should be installed in a manner that mimics the existing stream pattern. This will
enhance the passage of aquatic life by: (1) depositing and retaining sediment in the barrel,
(2) maintaining channel depth and flow regimes, and (3) providing resting places for fish and
other aquatic organisms.

Low Impact Development
The Service is concerned about the potential stormwater-mediated impacts to streams and
wetlands onsite. Where detention ponds are used, storm-water outlets should drain through a
vegetated area prior to reaching any natural stream or wetland area. Detention structures should
be designed to allow for the slow discharge of storm water, attenuating the potential adverse
effects of storm-water surges; thermal spikes; and sediment, nutrient, and chemical discharges.
Since the purpose of storm-water-control is to protect streams and wetlands, no
storm-water-control measures or best management practices should be installed within any
stream (perennial or intermittent) or wetland. We recommend that retention ponds be located
at least 750 feet from small wetlands to minimize hydrologic disturbance and ecological
function.

We also recommend that consideration be given to the use of pervious materials (i.e., pervious
concrete, interlocking/open paving blocks, etc.) for the construction of roads, driveways,
sidewalks, etc. Pervious surfaces minimize changes to the hydrology of the watershed and can
be used to facilitate groundwater recharge. Pervious materials are also less likely to absorb and
store heat and allow the cooler soil below to cool the pavement. Additionally, pervious concrete
requires less maintenance and is less susceptible to freeze/thaw cracking due to large voids
within the concrete.

The Service appreciates the opportunity to provide these comments. Please contact Mr. Byron
Hamstead of our staff at 828/258-3939, Ext. 225, if you have any questions. In any future
correspondence concerning this project, please reference our Log Number 4-2-19-245.

RE: Olympic Relief High School
Dear Joshua Kotheimer:
The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide
information about natural heritage resources for the project referenced above.
A query of the NCNHP database indicates that there are records for rare species, important natural
communities, natural areas, and/or conservation/managed areas within the proposed project
boundary. These results are presented in the attached ‘Documented Occurrences’ tables and map.
The attached ‘Potential Occurrences’ table summarizes rare species and natural communities that
have been documented within a one-mile radius of the property boundary. The proximity of these
records suggests that these natural heritage elements may potentially be present in the project area
if suitable habitat exists. Tables of natural areas and conservation/managed areas within a one-mile
radius of the project area, if any, are also included in this report.
If a Federally-listed species is documented within the project area or indicated within a one-mile
radius of the project area, the NCNHP recommends contacting the US Fish and Wildlife Service
(USFWS) for guidance. Contact information for USFWS offices in North Carolina is found here:
https://www.fws.gov/offices/Directory/ListOffices.cfm?statecode=37.
Please note that natural heritage element data are maintained for the purposes of conservation
planning, project review, and scientific research, and are not intended for use as the primary criteria
for regulatory decisions. Information provided by the NCNHP database may not be published
without prior written notification to the NCNHP, and the NCNHP must be credited as an information
source in these publications. Maps of NCNHP data may not be redistributed without permission.
Also please note that the NC Natural Heritage Program may follow this letter with additional
correspondence if a Dedicated Nature Preserve, Registered Heritage Area, Clean Water
Management Trust Fund easement, or an occurrence of a Federally-listed species is documented
near the project area.
If you have questions regarding the information provided in this letter or need additional assistance,
please contact Rodney A. Butler at [e-mail] or 919-707-8603.

No Element Occurrences are Documented within the Project Area
There are no documented element occurrences (of medium to very high accuracy) that intersect with the project area. Please note, however, that although the
NCNHP database does not show records for rare species within the project area, it does not necessarily mean that they are not present; it may simply mean that
the area has not been surveyed. The use of Natural Heritage Program data should not be substituted for actual field surveys if needed, particularly if the project
area contains suitable habitat for rare species. If rare species are found, the NCNHP would appreciate receiving this information so that we may update our
database.
