Project Description – Midwood
The Midwood project site consists of one (1) parcel of land totaling approximately 38.50 acres
that is located south of Route 55 (John Marshall Highway) in Haymarket, Virginia. The project
site is further identified by physical address 15411 John Marshall Highway and is now or
previously was a portion of Prince William County (County) GPIN 7298-41-5235. The terrain of
the project site consists of gentle slopes and level areas and is within the Broad Run drainage
basin. The project site is currently mostly wooded, undeveloped land with some open fields.
A. Purpose and Need
The purpose of the project is the construction of two (2) warehouse-type buildings that will be
utilized as data center facilities to meet increased regional demand for data services. The
project will also include utilities, access/driveways, and a stormwater management pond
necessary to serve the data center facilities. The buildings and related infrastructure will be
constructed in compliance with applicable site development plans, building codes, and site
zoning requirements. The project site is located within a Planned Business District in which data
centers are a by-right use, indicating that the County has determined that this location is
appropriate for data center buildings and associated infrastructure.
The project is needed so that the Applicant’s infrastructure can maintain secure and reliable
network connectivity and cloud infrastructure to the Applicant’s customers while keeping pace
with growing customer demand. Demand for the Applicant’s compute, storage, database, and
other computational service offerings is extremely high and growing in this region. This growth
is driven, in part, by a rapid increase in the number of companies, government agencies and
academic institutions that are decreasing their ownership of data facilities and migrating to
third-party cloud infrastructure because of technical complexities and the need for greater
security and reliability. Cloud computing provides an opportunity for these entities to replace
up-front capital infrastructure expenses with low variable costs that scale with their businesses.
There are a significant number of regional tech companies, start-ups, government agencies and
academic institutions whose need for data services from the Applicant grows annually. For
example, the Applicant experienced year-over-year demand growth of 69% in 2013, 49% in
2014, and 70% in 2015, and projections are that this growth will continue.
B. Wetland Impacts
The Waters of the U.S. and wetland boundaries were delineated by Wetlands Studies and
Solutions, Inc. (WSSI) in October 2005, and reconfirmed by a jurisdictional determination issued
by the U.S. Army Corps of Engineers (USACE) dated March 9, 2011 (NAO-2006-01343-arl) (see
Appendix I). Please note that this delineation includes additional land, west of the Midwood
project site. This portion of land is not owned by this Applicant and is not part of the Applicant’s
project. This JD has also since expired. It is important to note that TNT conducted a wetland
delineation in 2016 and submitted a new request for a jurisdictional determination on March
15, 2016; a response has not been received to-date regarding the status of this request.
As shown on the FEMA Flood Insurance Rate Map included as Appendix V (Map No.
51153C0059D, Map Effective Date: January 5, 1995), a floodplain is located along the southern
boundary of the project site.
8b
An Overall Wetlands Impact Map has been included in Appendix VIII and depicts the proposed
site plan and jurisdictional wetlands and streams. Based on the proposed site plan, which has
been modified from its original configuration to avoid and minimize impacts to the maximum
extent practicable, 991 linear feet (6,674 square feet) of intermittent stream, and 0.10 acres
(4,222 square feet) of palustrine forested wetland (PFO) will be permanently impacted. An
additional 14 linear feet (103 square feet) of intermittent stream channel will be temporarily
impacted for the installation of an 8” watermain. These unavoidable impacts to jurisdictional
waters are necessary in order to accomplish the project purpose.
Practicable Alternatives
As described below, alternative sites for the project were evaluated based on geography, capital
investment, facility sizes, utility requirements, real estate requirements, and
telecommunications redundancy, among other factors.
The project site was selected based on a quantitative and qualitative analysis with regard to
energy costs, water rates, permitting fees, construction expenses, tax rates, and labor
quality/costs among other factors that are relevant and pertinent to the project objectives. A
detailed evaluation identified the project site as the only practicable alternative for the project.
Site specific alternatives have been considered for this project, such as realignment and/or
reconfiguration of the buildings, and changes have been made to the original layout to both
avoid and minimize impacts. With these changes made, the Applicant believes there are no
practicable onsite alternatives with less adverse effects on streams, wetlands, and the aquatic
community than the project as now proposed. The Applicant has considerable investment in
the project in its current configuration. Any other configuration is not technically or practically
feasible to meet the project’s purpose. The alternative configuration is included in Appendix III
demonstrating the alternate layout disturbs 0.14 acre more wetland than the currently
proposed configuration.
Avoidance and Minimization
The Applicant, land planners, and engineers have considered all reasonable methods of avoiding
and minimizing impacts of the site to jurisdictional wetlands and streams. The Applicant has
reduced the larger building’s footprint by eliminating the material and equipment storage area
thereby avoiding impact to 0.14 acres of forested wetland. The Applicant configured the
proposed development plan so that approximately 676 linear feet of intermittent stream is
being preserved onsite. Previous preliminary development plans called for additional wetland
and stream impacts. For example, additional secondary impacts under the preliminary plans
would have resulted in an additional 700 linear feet of intermittent stream impact; however, the
proposed design has rerouted flow to the stream in order to mimic pre-construction flow and
conditions and maintain downstream hydrology. Rotating the buildings, however, is not
feasible because: 1) an alternate layout would disturb a greater amount of wetlands than the
current configuration; 2) an alternate layout would not fit within the property line and
conservation easement areas; and 3) the approved entrance location cannot be revised.
8c
In addition, the Applicant will take steps to minimize the generation of stormwater onsite and
lessen any impacts to streams. Because any increase in stormwater from the site has the
potential to damage downstream properties, all offsite stormwater draining to the site will be
diverted around the developed area. Additionally, during construction, stormwater from the
developed area will be directed to and controlled by constructed erosion control measures;
after construction, stormwater from the developed area will be directed to and controlled by
the onsite stormwater management structures.
The Applicant believes that further avoidance and minimization of impact is not possible and
that the current configuration of the proposed project is the Least Environmentally Damaging
Practicable Alternative (LEDPA). Due to the location and extent of streams onsite, permanent
impacts to 991 linear feet (6,674 square feet) of intermittent stream and 0.10 acres (4,222
square feet) of palustrine forested wetland (PFO), as well as a temporary impact to 14 linear
feet (103 square feet) of intermittent stream are unavoidable. Additional information regarding
avoidance and minimization of impacts to jurisdictional wetlands and streams is provided in
Appendix III.

WETLAND DELINEATION REPORT & USACE JURISDICTIONAL DETERMINATION LETTER

Reference: Wetland Reconfirmation Letter, Midwood, Prince William County, Virginia
Dear Mr. Lim,
At your request and in general accordance with TNT Environmental, Inc. (TNT) proposal number 787,
dated February 1, 2016, TNT conducted a site reconnaissance on the above-referenced project site to
evaluate the site in order to acquire a valid jurisdictional determination.
The Midwood project site consists of three parcels of land totaling approximately 61.6 acres and located
south of Route 55 (John Marshall Highway) in Haymarket, Virginia. The project site is further identified
by physical address 15411 John Marshall Highway and Prince William County GPINs: 7298-42-4228,
7298-41-5235, and 7298-32-9522. The terrain of the project site consists of gentle slopes and level
areas and is within the Broad Run drainage basin. The project site is currently mostly wooded,
undeveloped land with some open fields.
The Waters of the U.S. and wetland boundaries were delineated by Wetlands Studies and Solutions, Inc.
(WSSI) in October 2005, and reconfirmed during a jurisdictional determination (JD) with the U.S. Army
Corps of Engineers (USACE) dated March 9, 2011 (NAO-2006-01343-arl). The current JD will expire on
March 9, 2016. Please note that this former delineation includes additional land, west of the Midwood
project site. This portion of land is now owned by others and is not part of this evaluation.
TNT conducted a pedestrian survey of the project site on Friday, February 12, 2016. As shown on the
enclosed wetland delineation map and based on the site survey, the majority of wetlands and Waters of
the U.S. onsite appear to be unchanged since the former wetland delineation. It is important to note
that an isolated feature in the south-central portion of the site was formerly mapped as a Palustrine
Forested Wetland (PFO); however, during TNT’s field assessment, this area did not exhibit hydric soils or
a dominance of hydrophytic vegetation. Further, this feature does not and formerly was not mapped as
having a significant nexus to any other jurisdictional features. It is important to note that no data points
within this area were included in the previous wetland delineation.

Please refer to the enclosed Wetland Delineation Map showing the potentially jurisdictional wetlands
and Waters of the U.S., per TNT’s reconnaissance. TNT collected data points within and outside wetland
areas to characterize these features and define their boundaries. These data points and photographs
are enclosed with this letter. Data Points from the previous wetland delineation by WSSI were collected
using the 1987 Manual and the Eastern Mountains and Piedmont Regional Supplement and should be
referred to for those additional wetlands that remain unchanged. The findings on the enclosed Wetland
Delineation Map shall be considered preliminary until approved through a Jurisdictional Determination.
We appreciate the opportunity to work with you on this project. If you have any questions, please feel
free to contact us at any time at (703) 466-5123.

Northern Virginia Regulatory Section NAO-2006-01343-arl (North Fork Broad Run) Landservices, Inc Attn: Eugene Siegel 10432 Balls Ford Road, Suite 300 Manassas, Virginia 20109 Dear Mr. Siegel: This letter is in regard to your request for an approved jurisdictional determination for waters of the U.S. (including wetlands) on the property known as the Midwood project site. The approximately 120 acre project site is located south of Route 55, west of Route 15 and north of the Southern Railroad in Prince William County, Virginia. An on-site jurisdictional determination has found waters and wetlands regulated under Section 10 of the Rivers and Harbors Act (33 U.S.C. 403) and/or Section 404 of the Clean Water Act (33 U.S.C. 1344) on the project site listed above. Non-tidal headwater wetlands; non-tidal adjacent wetlands and non-tidal streams have been identified on the site. This letter shall serve to confirm the wetlands and waters delineation by Wetland Studies and Solutions, Inc., as surveyed and shown on the map titled, "Waters of the U.S. Delineation – Midwood”, dated September, 2005 with a final revision date of March 22, 2006.
Our basis for this determination is the application of the Corps' 1987 Wetland Delineation Manual, Eastern Mountains and Piedmont Regional Supplement and the positive indicators of wetland hydrology, hydric soils, and hydrophytic vegetation. The wetland is a water of the United States and is part of a tributary system to interstate waters (33 CFR 328.3(a)). These waters meet the Corps' definition of waters of the United States, are part of a tributary system to interstate waters (33 CFR 328.3 (a)) and have an ordinary high water mark (or high tide line). Any mechanized landclearing that disturbs the soil surface, such as with a bulldozer and/or root rake, and/or any structure, fill or excavation in the [wetlands and/or streams and/or ditches and/or ponds] on this site may require a Department of the Army permit and possibly authorization by state and local authorities. Your proposed work may require a Virginia Water Protection Permit from the Virginia Department of Environmental Quality (DEQ) and/or a permit from the Virginia Marine Resources Commission (VMRC). Please obtain all required permits before starting work in the delineated waters/wetland areas. This letter contains an approved jurisdictional determination for your subject site. If you object to this determination, you may request an administrative appeal under Corps regulations at 33 CFR Part 33 1. Enclosed you will find a Notification of Appeal Process (NAP) fact sheet and Request for Appeal (RFA) form. If you request to appeal this determination you must submit a completed RFA form to the North Atlantic Division Office at the following address:

AVOIDANCE & MINIMIZATION ANALYSIS
Avoidance and Minimization Analysis
The Applicant proposes to construct two warehouse-type buildings utilized by data center
facilities and their associated equipment in Prince William County, Virginia. The development
will include warehouse buildings, associated utilities and infrastructure including
access/driveways, and a stormwater management pond.
Pursuant to the Memorandum of Agreement between the Environmental Protection Agency and
Department of the Army Concerning the Determination of Mitigation under the Clean Water Act
Section 404(b)(1) Guidelines and the Virginia Water Protection Permit regulations (9 VAC 25-
210-90.C and 9 VAC 25-210-115), applicants for state permits to impact waters of the State must
demonstrate that impacts to these waters have been avoided and minimized to the maximum
extent practicable. Under the Section 404 (b)(1) Guidelines (40 CFR §§ 230.1-230.80) for non-
water dependent uses, the applicant must demonstrate that the proposed project is the Least
Environmentally Damaging Practicable Alternative (LEDPA) by demonstrating that all
“appropriate and practicable” steps to avoid and minimize impacts on the project site have been
taken.
The concept of practicability is an important component of the impact avoidance, minimization,
and mitigation requirements of the U.S. Environmental Protection Agency (EPA), U.S. Army
Corps of Engineers (COE), and Virginia Department of Environmental Quality (DEQ). The term
“practicable” appears numerous times in the Virginia Water Protection Permit regulations, EPA’s
Section 404(b)(1) Guidelines, an the Memorandum of Agreement between the Environmental
Protection Agency and Department of the Army Concerning the Determination of Mitigation
under the Clean Water Act Section 404 (b)(1) Guidelines. This term is defined identically in the
Virginia Water Protection Permit regulation (9 VAC 25-210-10) and EPA’s Section 404 (b)(1)
Guidelines (40 CFR §§ 230.1-230.80) as “available and capable of being done after taking into
consideration cost, existing technology, and logistics in light of overall project purposes.” The
COE’s wetlands regulations (33 CFR §§ 320-331) also recognized economic issues as one of the
criteria to be considered in determining whether the COE should issue a permit, and these
regulations state that the practicability of alternatives to accomplish the objective of the
proposed project must be considered in permit decisions (33 CFR § 320.4(a)(1)). Thus, economic
interests and the purpose of a proposed project may be taken into account when analyzing
project alternatives and determining the Least Environmentally Damaging Practicable
Alternative (LEDPA).
Analysis of Practicable Onsite Alternatives
In order for the project purpose to be practicably achieved, the wetlands and streams must be
impacted to allow for the construction of the buildings, driveways, utilities, and stormwater
management pond necessary to serve the proposed usage. Given the location of the project
site and because the amount of fill located in jurisdictional wetlands and Waters has been
limited to the minimum necessary to accomplish these requirements, there is no practicable
alternative that will allow for the construction of this development within the project boundary
with less adverse effects of streams, wetlands, and the aquatic community than the proposed
project. Adjacent parcels within the same area are either insufficient to accommodate project
needs or would result in a greater adverse effect on streams, wetlands, and the aquatic
communities. Additionally, rotation of the current proposed buildings’ position results in
additional impacts to wetlands and other Waters onsite. The Applicant has done considerable
re-designing and shifting to avoid impacts to the eastern wetland and stream systems. Further,
secondary impacts have been avoided by redesigning the stormwater pond’s outfall to provide
hydrology to the stream at Impact #1.
The buildings are user-specific buildings and the footprint of the buildings are minimized as
much as possible for the proposed equipment. Any decrease in the building footprint would
make the site infeasible for the Applicant. All three buildings have been minimized to the
smallest size possible for the user; please refer to the previous site plans enclosed in this
Appendix.
The building sizes and development plan have been significantly reduced (to the extent
practicable for allowing the project to meet its goals) since the previous application submission,
and the development now avoids impacts to the eastern wetland and stream system onsite,
preserving 11,823 square feet (0.27 acres) of palustrine forested wetlands and 551 linear feet of
stream channel.
The stormwater management pond cannot be moved or redesigned without impacting
additional wetlands along the eastern side of the property. The use of smaller, multiple ponds
would increase the limits of disturbance along with increasing the amount of wetland impacts.
The culvert along the eastern property line allows water to bypass the site that drains into the
existing wetland in that area. Therefore, there are no practicable onsite alternatives for the
proposed location of the project.
Based on the proposed development plan, 551 linear feet of intermittent stream are being
preserved onsite in addition to 11,823 square feet (0.27 acres) of forested wetlands. Previous
preliminary development plans called for additional wetland and stream impacts (please refer to
the enclosed Site Plans in this Appendix); however these plans were discarded based on their
encroachment into wetlands and waters of the U.S. For example, additional secondary impacts
would have resulted in an additional 700 linear feet of intermittent stream impact; however, the
proposed design has rerouted flow to the stream in order to mimic pre-construction flow and
conditions and maintain downstream hydrology. The proposed development has also been
reduced to avoid 6,154 square feet of palustrine forested wetland (0.14 acres) which were
formerly proposed; this avoidance was accomplished by minimizing the building to the minimal
footprint necessary for the user. The Applicant has also looked at rotating the buildings 90
degrees, which resulted in impacts to the eastern wetland/stream system that is now being
preserved by the proposed site plan.
The Applicant, land planners and engineers have worked to avoid and minimize impacts on the
site to the maximum extent practicable. The layout of the proposed development was placed in
the only location feasible to suit the proposed usage. Due to the size of the project area and
development constraints, no alternatives exist for the planned development.
Discussion of Proposed Wetland/Waters of the U.S. Impacts
The proposed impacts consist of general site grading for the construction of the proposed
roadway, utilities, and stormwater management facility outfall necessary to serve the proposed
usage. There are five (5) impact areas consisting of four (4) permanent and one (1) temporary
impact, as described below.
Impact #1, which is permanent, will result from filling 991 linear feet (6,674 square feet) of
intermittent stream (R4) associated with the construction of the buildings and associated
infrastructure. The permanent impacts proposed in this area due to the grading and placement
of fill material and the central location of the stream onsite. This impact is necessary in order to
accomplish project goals.
Impact #2, which is permanent, will result from filling 2,704 square feet (0.06 acre) of palustrine
forested wetland (PFO) associated with the construction of the buildings and associated
infrastructure. The permanent impacts proposed in this area due to the grading and placement
of fill material and the central location of the stream onsite. This impact is necessary in order to
accomplish project goals.
Impact #3, which is permanent, will result from filling 1,312 square feet (0.03 acre) of palustrine
forested wetland (PFO) associated with the construction of the buildings and associated
infrastructure. The permanent impacts proposed in this area due to the grading and placement
of fill material and the central location of the stream onsite. This impact is necessary in order to
accomplish project goals.
Impact #4, which is temporary, will result from the installation of a water main required to serve
the proposed development. This utility is being installed at the request of Prince William
County. This impact will result in the temporary disturbance to 14 linear feet (103 square feet)
of intermittent stream. This impact is necessary in order to accomplish project goals. These
areas will be excavated to the necessary depth for utility installation and then returned to pre-
construction contours.
Impacts #5, which is permanent, will result from filling 206 square feet (0.005 acre) of palustrine
forested wetland (PFO). The permanent impacts proposed in this area due to the grading and
placement of fill material. This impact is necessary in order to accomplish project goals.
Due to the location and extent of streams onsite, the permanent impacts to 991 linear feet
(6,674 square feet) of intermittent stream and 0.10-acres (4,222 square feet) of palustrine
forested wetland (PFO), and temporary impacts to 14 linear feet (103 square feet) of
intermittent stream proposed in this JPA are unavoidable.

APPENDIX IV
CONCEPTUAL MITIGATION PLAN
Conceptual Mitigation Plan
The Applicant proposes to make payment to a U.S. Army Corps of Engineers and Virginia
Department of Environmental Quality approved wetland mitigation bank to compensate for the
impacts to 0.10 acres of palustrine forested (PFO) wetland impacts as shown below:
Wetland Compensation Requirements
Cowardin
Classification Impact (Acres) Compensation Ratio
Compensation
Requirement (credits)
PFO 0.10 2:1 0.20
Total 0.10 0.20
In addition to wetland impacts, the proposed project will result in permanent impacts to 991 linear
feet of intermittent stream. An additional 14 linear feet of intermittent stream will be temporarily
impacted for the installation of an 8” watermain; due to the temporary nature of this impact,
mitigation is not warranted. Permanent impacts will be mitigated with the purchase of credits from
an approved stream bank as shown below:
Stream Compensation Requirements
Cowardin
Classification Impact (Linear feet)
Reach Condition
Index (from USM
Forms, attached)
Compensation
Requirement (credits)
R4 991 1.08 1,070
Total 991 1,070
The Applicant proposes to compensate for the permanent impacts though the purchase of 1,070
credits from a U.S. Army Corps of Engineers and Virginia Department of Environmental Quality
approved stream mitigation bank prior to the commencement of construction to offset the loss of
991 linear feet of intermittent stream.
It is the opinion of TNT that there will be no net loss of functions and values and the proposed
mitigation will fully compensate for the impacts to wetlands and waters of the U.S. proposed in this
JPA.
