RE: Pre -Construction Notification — NWP 39; General Certification 4092; Neuse River Buffer
Authorization Request
Mist Lake Facility Expansion
Durham County, North Carolina
Project #: 39722.001
Dear Mr. Sullivan and Mrs. Higgins:
On behalf of the City of Durham - Department of Water Management, Timmons Group is submitting a
Preconstruction Notification (PCN) for Nationwide Permit (NWP) 39, General Certification (GC) 4092, and
Neuse River Buffer Authorization Request associated with proposed construction of the Mist Lake Facility
Expansion located at 1600 Mist Lake Drive in Durham, North Carolina. The project site is bound by 1-85
to the south, an unnamed tributary to the west, and Camden Road to the north. The purpose of the
proposed project is to expand the existing facility at Mist Lake, in order to accommodate multiple City of
Durham — Department of Water Management (DWM) divisions and allow for potential growth over the next
20 years. To accomplish the goals of the proposed project, approximately 96 feet of stream impact is
proposed due to infrastructure and facility layout improvements. In addition, a second entrance road to
Camden Avenue is proposed due to safety requirements. As a result, a bridge is proposed to cross Stream
A (Goose Creek) with the footers of the bridge placed outside the jurisdictional limits of Stream A, therefore,
avoiding impacts to Stream A. Neuse River Riparian Buffer impacts are also proposed as part of the project.

PROJECT HISTORY & EXISTING CONDITIONS:
The project site encompasses approximately 55 acres and is located at 1600 Mist Lake Drive in Durham,
North Carolina (see Figure 1: Vicinity Map). The project site is bound by 1-85 to the south and east, Goose
Creek to the west, and Camden Road to the north. The project site is located within the Neuse River Basin
(HUC 030202010403) and within the Upper Falls Lake watershed. Adjacent lands are composed of
primarily industrial properties intermixed with undeveloped land. The project site drains to unnamed
tributaries, where surface waters enter into Goose Creek. Surface waters from Goose Creek flow north to
Ellerbee Creek before discharging into Falls Lake, northeast of the project site. There is a floodway and
100 -year floodplain area associated with Goose Creek. The project site currently houses a division of the
City of Durham — Department of Water Management (DWM) in a 20 acre facility, along with associated
vehicles, equipment and inventory. The undeveloped areas, mainly along the floodplain, are dominated by
mid -successional mixed pine and hardwood forest with mixed hardwoods adjacent to the drainage ways.
The topography slopes gradually from the southwestern corner to the north and east portion of the project
limits.
A stream and wetland delineation was conducted by the McAdams Company. NC DWR issued a Neuse
River Buffer Determination (NBRRO# 17-192; July 19 ,2017). An on-site field confirmation conducted by
USACE (USACE Action ID.: SAW -2017-01649) on September 19, 2017. A written Jurisdictional
Determination is forthcoming. Based on the delineation there are approximately 14.21 acres of wetland
and approximately 5,644.9 feet of stream located within the project site. Timmons Group conducted a
Threatened and Endangered Species Assessment for the Mist Lake Facility Expansion project. There were
no Federally Threatened or Endangered species observed during the field survey conducted during the
week of July 10, 2017. Based on the field investigations conducted by the Timmons Group, a biological
opinion of "No Effect" was rendered for the Michaux's sumac, and smooth coneflower. A Threatened or
Endangered Species Assessment Initial Scoping letter was submitted to the USFWS on September 7,
2017. A response from USFWS is forth coming. A Riparian Buffer Variance Request was prepared by the
Timmons Group on behalf of the City of Durham — Department of Water Management and submitted to NC
DWR on August 31, 2017 due to buffer impacts associated with infrastructure and site layout improvements
and are described below.
PROPOSED PROJECT:
The purpose of the proposed project is to expand the existing facility at Mist Lake, in order to accommodate
multiple City of Durham — Department of Water Management (DWM) divisions and allow for potential growth
over the next 20 years. The DWM Mist Lake Facilities Expansion project consists of two buildings totaling
approximately 116,000 square feet: one to house the administration, warehouse, and shops and the other
to hold the equipment maintenance shop. The project is consistent with the zoning requirements for this
area (IL - industrial) and is being undertaken to consolidate multiple divisions at one location.
The City of Durham — Department of Water Management (DWM) currently operates a division at 1600 Mist
Lake Drive (North Campus). This 20 acre facility houses approximately 82 staff of the Administration, Plant
Engineering & Maintenance, Regulatory Compliance, and Utility Engineering divisions of the Department,
along with associated vehicles, equipment, and inventory. Currently, 145 DWM Water & Sewer
Maintenance (WSM) employees are co -housed at a second location on Martin Luther King, Jr. Drive, the
Public Works Operations Center (PWOC) along with Public Works staff. The WSM workgroups at PWOC
are responsible for Outfall Maintenance, Rehabilitation Maintenance, Meter Reading, Meter Maintenance,
Service Installations, and Mainline Installations, along with the necessary vehicles, light and heavy
equipment, and inventory to maintain and operate approximately 2,600 miles (combined) of water and

sewer mains, 8,148 hydrants, 25,896 water valves, and more than 83,000 water meters. The project will
expand the DWM Mist Lake facility to accommodate the relocation of the WSM Division from the PWOC
facility to the Mist Lake complex and potential growth over the next 20 years. To accomplish the goals of
the project, impacts to streams and riparian buffers are proposed.
The proposed infrastructure and facility layout will impact Stream H and associated riparian buffers. In
addition, a second entrance road to Camden Avenue is proposed due to safety requirements associated
with providing safe ingress and egress to light and heavy equipment and to allow for multiple access points
for emergency responders (i.e. fire, EMS, etc.). As a result, a bridge is proposed to cross Stream A (Goose
Cre with the footers of the bridge placed outside the jurisdictional limits of Stream A, therefore, avoiding
impacts to Stream A. However, there are riparian buffer impacts along Stream A associated the
construction of the proposed second entrance road to Camden Avenue. In addition, the project proposes
to construct a chain link within small portions of the riparian buffer associated with Streams B and D.
Construction of the chain link will create minimal disturbance within the riparian buffers.

Stormwater Managamnt
A suite of stormwater devices (e.g. underground sand filters, underground detention, and filter strips) for
stormwater treatment. This reduced the need for detention ponds, which further reduced and minimized the
impacts to the adjacent stream channels, wetlands, and/or riparian buffers. The site is located within the
Upper Falls Lake Watershed, Neuse River Basin. The proposed development will result in 34.6% total built
upon area on the site. As part of the development, peak stormwater discharges for the 1 yr, 2yr and 10-24hr
storm will be controlled to ensure there is no increase in the peak stormwater discharge rates from the site.
The SCS method of analysis was used for the storm event calculations.
Total Disturbed acreage on the site is 21 -acres. Four underground sand filters, two underground detention
systems, and two level spreaders with filter strips are proposed for the treatment of the stormwater. There
are stream buffers surrounding the site, and careful planning has been utilized to avoid most of these buffer
and stream impacts. The proposed development will impact some areas of buffers and streams. No
wetland impacts are planned for this project. A bridge will be utilized in order to tie into Camden Avenue.
The bridge will cross over the floodway and Goose Creek while avoiding disturbance to the maximum extent
possible. The site will also have floodplain impacts which will be permitted through the City. There is no
offsite upstream run-off entering the developed portion of the site. Any upstream flow bypasses the site

and remains in the buffered streams. Stormwater piping is proposed for this site and measures have been
taken such that all stormwater runoff leaves the subject property with no increase in peak runoff.
Stormwater Quantity: One analysis point has been evaluated for compliance with stormwater ordinance
labeled Point W. Stormwater analysis point 'A' is located at the south property line. The runoff was
analyzed to determine the change in peak stormwater discharge rates for the 1 -yr, 2 -yr, 10 -yr and 100 -yr
storm events. A summary of the design calculations is provided below.
I With Detention I... I. I.
Note: Post -development Peak Runoff is less than Pre -development Peak Runoff
Stormwater Quality: By ordinance section 70-740, this project qualifies as a Redevelopment project, but we
will treat this project as new development. The Site is located in the Upper Falls Lake Basin where the
minimum nutrient removal requirements are 2.20-lbs/ac/yr of nitrogen and 0.33-lbs/ac/yr of phosphorous.
In the Upper Falls Lake Basin for new development, there is a 50% minimum of onsite nutrient treatment.
AVOIDANCE & MINIMIZATION:
Impacts to jurisdictional features and buffers were avoided and minimized to the maximum extent
practicable by incorporating resourceful site planning, including the utilization of the wetland delineation to
adjust the layout to avoid and minimize impacts. Avoidance and minimization measures were also
accomplished during the design phase of the Project.
The Applicant has avoided and minimized impacts to the greatest extent practicable given the Project's
purpose and need. The proposed 24,935 square feet of stream buffer impacts are the result of the
necessary infrastructure and facility layout, without which, the Project goals would not be realized. This
property has been owned since January 1997 and its purchase was intended for this proposed Project. If
the City cannot use the existing property to consolidate the five divisions then the initial investment on the
purchase of the property will be lost, additional property will need to be purchased to relieve the additional
space requirements needed at the remote facilities, as well, the property cannot be used to consolidate
multiple divisions in one location. Logistically this will cause inefficiencies, create other impacts associated
with the development of another property that are significantly more than the proposed Project, and will not
solve the original problems that were the impetus of consolidating the divisions at one location. In order to
provide adequate space for parking and buildings, a minimum of 21 acres of buildable land is necessary.
The southwestern portion of the site is relatively narrow and is constrained by setbacks along the Interstate
and wetlands to the north. A stream and associated buffer bi-sect the property in this area and cannot be
avoided.
An additional constraint to the site is the need to provide access for emergency vehicles in the event of a
fire. To comply with current IFC and local fire codes, pavement is proposed around the site, such that fire

with the development of another property that are significantly more than the proposed Project, and will not
solve the original problems that were the impetus of consolidating the divisions at one location. In order to
provide adequate space for parking and buildings, a minimum of 21 acres of buildable land is necessary.
The southwestern portion of the site is relatively narrow and is constrained by setbacks along the Interstate
and wetlands to the north. A stream and associated buffer bi-sect the property in this area and cannot be
avoided.
An additional constraint to the site is the need to provide access for emergency vehicles in the event of a
fire. To comply with current IFC and local fire codes, pavement is proposed around the site, such that fire

apparatus vehicles have access to within 150 feet from all parts of the building. To comply with this
requirement, impacts to the buffer cannot be avoided. Offsite alternative sites were explored for this Project;
however, in order to provide adequate building space and parking for all divisions, at least 21 acres of
buildable land are needed, as well as an adjacent roadway infrastructure that supports heavy truck use.
The current location allows for future growth, provides better utilization of existing personnel and equipment,
utilizes parts/tools warehousing and non -duplication of housing parts, provides for better internal
communication between divisions, and provides protection of parked vehicles and equipment during
flooding, which is now experienced at the current location of the Public Works WSM Division, located
southwest of this facility. In addition, the proposed layout provides more acceptable storage and in-house
work area conditions (e.g. dedicated pedestrian walkways), which provides for a safer work environment
for personnel, while utilizing the existing utility and road infrastructure.
Given the design constraints associated with a shared use facility (i.e. administration buildings,
maintenance warehouses, work vehicles, equipment storage) and the local zoning requirements, the
applicant has minimized impacts to the greatest extent practicable. Specifically, there is a setback
associated with Interstate 85 along the southern property boundary. This 50 foot setback limited useable
space for parking and buildings along the southern property line and pushed the development to the north,
towards the stream and stream buffer. Moreover, the southwestern portion of the property is bisected by a
stream and buffer, and in order to provide space for a building and parking, buffer impacts could not be
avoided. The applicant explored the use of retaining walls along the northern portion of the parking lot;
however, this option provided very limited avoidance, as space is still needed for parking and emergency
vehicle access. Furthermore, most of the vehicles and equipment being stored at the site are large
construction vehicles and equipment, which required more storage area than a passenger car or truck.
Construction equipment and vehicles require more space to maneuver (i.e. larger turning radii, larger
parking areas, etc.), as well, when being serviced these vehicles require large services bays, as well as
additional areas with the lay down area for the large equipment (lifts, hoists, cranes, etc.) needed to service
the larger equipment. Therefore, the typical parking requirements for an office building do not apply, and
are considerably larger based on the type and number of pieces of equipment. Approximately 368 parking
spaces are required for the site. This includes parking for the visitors, employees, and fleet vehicles (both
large and small), as well as the additional handicap spaces required by the City Ordinance. The original
layout (Appendix D — Original Layout) proposed impacts to wetlands and a stream channel in the northern
portion of the property for an entrance road and the proposed fill slope for the parking areas and pad sites
extended into the wetlands in the central portion of the property. The layout was re -designed, in order to
avoid impacts to the wetlands and stream channel through the use of retaining walls. The entrance road
from Camden Avenue is a safety requirement, in order to provide safe ingress and egress, as well as allow
for multiple access points for emergency responders (i.e. fire, EMS, etc.). The road was re -located in an
area that avoids impacts to streams and wetlands. Moreover, stream impacts have been completely
avoided through the use of bridge. In addition, impacts to riparian buffers have been minimized to the
maximum extent practicable by aligning the bridge through the buffer as close to 90 degrees as possible.
In an effort to confine the entire facility for security purposes, a chain link fence is proposed, in which, small
portions will be constructed within the riparian buffer associated with Streams B and D resulting in minimal
disturbance.
Other measures taken to minimize impacts include the use of a suite of stormwater devices (e.g.
underground sand filters, underground detention, and filter strips) for stormwater treatment. This reduced
the need for detention ponds, which further reduced and minimized the impacts to the adjacent stream
channels, wetlands, and/or riparian buffers. A project -specific Erosion and Sediment Control (ESC) plan
will be developed and submitted to Durham for approval of the land disturbing activity. The ESC plan will
be prepared in accordance with the North Carolina Erosion & Sediment Control Laws and Regulations and
the most current version of the Erosion & Sediment Control Planning and Design Manual. The ESC plan
will be approved by the locality prior to any land -disturbing activity associated with the Project. All regulated
land -disturbing activities associated with the Project, including on- and off- site access roads, staging areas,
borrow areas, stockpiles, and soil intentionally transported from the Project Area will be covered by the
project specific ESC plan. During construction activities, the ESC Best Management Practices (BMPs) will

be inspected and maintained throughout the life of the construction activity providing for enhanced
protection for the avoided jurisdictional areas and further minimizing impacts to the aquatic resources.
Measures will be taken to prevent oil, tar, trash, debris and other pollutants from entering the adjacent
jurisdictional streams and wetlands. Any excess excavated materials not utilized as back fill will be placed
and contained within upland areas and permanently stabilized to prevent erosion into adjacent jurisdictional
streams and wetlands. Therefore, stockpiling of excavated material within jurisdictional streams and
wetlands will be strictly prohibited as part of the construction of this project. All project construction activities
initiated within jurisdictional streams and wetlands will be carried to completion in an expeditious manner
to minimize the period of disturbance within the jurisdictional streams and wetlands.
MITIGATION:
The Mist Lake Facility Expansion proposes to impact 96 feet of intermittent stream (Stream H); and
therefore, the applicant does not propose compensatory mitigation for these impacts at this time due to the
avoidance minimizations measures described above. In addition, stream A (Goose Creek) will be crossed
by a bridge for the purposes of a proposed second entrance road to Camden Avenue due to safety
requirements associated with providing safe ingress and egress to light and heavy equipment and to allow
for multiple access points for emergency responders (i.e. fire, EMS, etc.). The footers of the proposed
bridge will be placed outside the jurisdictional limits Stream A; therefore, impacts to Stream A will be avoided
and compensatory mitigation is not proposed. The proposed stream buffer impacts associated with the
bridge crossing of Goose Creek are considered an Allowable Use within the stream buffer in accordance
with 15A NCAC 02B .0259 Neuse River Basin; and therefore, compensatory mitigation is not required nor
is it proposed at this time.
As noted above, a Riparian Buffer Variance Request was prepared by the Timmons Group on behalf of the
City of Durham — Department of Water Management and submitted to NC DWR on August 31, 2017 due
to buffer impacts associated with infrastructure and site layout improvements. Compensatory mitigation for
these unavoidable riparian impacts will be achieved through the purchase of off-site mitigation credits from
a mitigation bank, which is approved for use in the Neuse Watershed (Hydrologic Unit Code 03020201).
Buffer mitigation credits will be purchased using the Standard Compensatory Mitigation Ratios at ratios of
3:1 for Zone 1 (39,249 SF) and 1.5:1 for Zone 2 (17,778 SF). This equates to a total compensatory
mitigation obligation of 57,027 SF of buffer credits. A credit availability letter from an approved bank located
in HUC 03020201 was obtained from Wildlands Holdings for the North Fork Little River Buffer Bank
(Compensatory Mitigation Availability Letter; Wildlands Holdings; July 27, 2017).
SUMMARY:
The proposed Mist Lake Facility Expansion is required to accommodate multiple City of Durham —
Department of Water Management (DWM) divisions and allow for potential growth over the next 20 years.
To accomplish the goals of the proposed project, approximately 96 feet of stream impact is proposed due
to infrastructure and facility layout improvements. In addition, a second entrance road to Camden Avenue
is proposed due to safety requirements. As a result, a bridge is proposed to cross Stream A with the footers
of the bridge placed outside the jurisdictional limits of Stream A, therefore, avoiding impacts to Stream A.
Neuse River Riparian Buffer impacts are also proposed as part of the project. The applicant proposes to
compensate for unavoidable riparian buffer impacts by payment into the North Fork Little River Buffer Bank
(Compensatory Mitigation Availability Letter; Wildlands Holdings; July 27, 2017). The entire Mist Lake
Expansion project is a single and complete project with appropriate land use control and stormwater
measures in place for specific areas which require them.

Therefore at this time, we are requesting confirmation that the proposed project qualifies under the
conditions of NWP 39 and GC 4092. In addition, we are requesting authorization of the proposed project
under the Neuse River Buffer Rules. Consideration of this project is greatly appreciated. If you should
have any questions or require additional information, please do not hesitate to contact me at (984)255-
2361.

_ . ..... ..... .
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 project site encompasses approximately 55 acres and is located at 1600 Mist Lake Drive, in Durham
County, North Carolina (see Figure 1: Vicinity Map). It is bound by 1-85 to the south, an unnamed tributary
to the west, and Camden Road to the north. The site is located within the Neuse River Basin (HUC
030202010403) and within the Upper Falls Lake watershed. The adjacent lands are composed of primarily
industrial properties intermixed with undeveloped land. The project site drains to unnamed tributaries, where
surface waters enter into Goose Creek. Surface waters from Goose Creek flow north to Ellerbee Creek
before discharging into Falls Lake, northeast of the project site. The project site currently houses a division of
the City of Durham — Department of Water Management (DWM) in a 20 acre facility, along with associated
vehicles, equipment and inventory. The undeveloped areas, mainly along the floodplain, are dominated by
mid -successional mixed pine and hardwood forest with mixed hardwoods adjacent to the drainage ways.
The topography slopes gradually from the southwestern corner to the north and east portion of the project
limits.

3c List the total estimated linear feet of all existing streams (intermittent and perennial) on the property: +/- 5,644.9 LF
3d Explain the purpose of the proposed project:
The purpose of the proposed project is to expand the existing facility at Mist Lake, in order to accommodate
multiple City of Durham — Department of Water Management (DWM) divisions and allow for potential growth
over the next 20 years. The DWM Mist Lake Facilities Expansion project consists of two buildings totaling
approximately 116,000 square feet: one to house the administration, warehouse, and shops and the other to
hold the equipment maintenance shop. The project is consistent with the zoning requirements for this area
(IL - industrial) and is being undertaken to consolidate multiple divisions at one location.
3e Describe the overall project in detail, including the type of equipment to be used:
The City of Durham — Department of Water Management (DWM) currently operates a division at 1600 Mist
Lake Drive (North Campus). This 20 acre facility houses approximately 82 staff of the Administration, Plant
Engineering & Maintenance, Regulatory Compliance, and Utility Engineering divisions of the Department,
along with associated vehicles, equipment, and inventory. Currently, 145 DWM Water & Sewer Maintenance
(WSM) employees are co -housed at a second location on Martin Luther King, Jr. Drive, the Public Works
Operations Center (PWOC) along with Public Works staff. The WSM workgroups at PWOC are responsible
for Outfall Maintenance, Rehabilitation Maintenance, Meter Reading, Meter Maintenance, Service
Installations, and Mainline Installations, along with the necessary vehicles, light and heavy equipment, and
inventory to maintain and operate approximately 2,600 miles (combined) of water and sewer mains, 8,148
hydrants, 25,896 water valves, and more than 83,000 water meters. The project will expand the DWM Mist
Lake facility to accommodate the relocation of the WSM Division from the PWOC facility to the Mist Lake
complex and potential growth over the next 20 years. To accomplish the goals of the project, impacts to
streams and riparian buffers are proposed. The proposed infrastructure and facility layout will impact Stream
H and associated riparian buffers. In addition, a second entrance road to Camden Avenue is proposed due
to safety requirements associated with providing safe ingress and egress to light and heavy equipment and
to allow for multiple access points for emergency responders (i.e. fire, EMS, etc.). As a result, a bridge is
proposed to cross Stream A (Goose Creek) with the footers of the bridge placed outside the jurisdictional
limits of Stream A, therefore, avoiding impacts to Stream A. However, there are riparian buffer impacts along
Stream A associated the construction of the proposed second entrance road to Camden Avenue. In addition,
the project proposes to construct a chain link within small portions of the riparian buffer associated with
Streams B and D. Construction of the chain link will create minimal disturbance within the riparian buffers.
Traditional equipment will be used consisting of front-end loaders, bulldozers, paving equipment, graders, and
earth movers to construct the proposed project.

Riparian Buffer Impact B1 Parkin (Fire Lane): Riparian Buffer Variance Request was prepared by the Timmons
Group on behalf of the City of Durham — Department of Water Management and submitted to NC DWR on
August 31, 2017.
Riparian Buffer impact B2 (Bridge): Riparian buffer impacts are proposed associated with bridge placement for the
entrance road to Camden Avenue. In accordance with the Neuse River Riparian Buffer Rules (15A NCAC 02B
.0233) Table of Uses, bridges are an allowable use and mitigation is not required. Stream impacts have been
completely avoided through the use of a bridge. Impacts to riparian buffers have been minimized to the
maximum extent practicable by aligning the bridge through the buffer as close to 90 degrees as possible.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1 a Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Impacts to jurisdictional features and buffers were avoided and minimized to the maximum extent practicable by
incorporating resourceful site planning, including the utilization of the wetland delineation to adjust the layout to
avoid and minimize impacts. Avoidance and minimization measures were also accomplished during the design
phase of the Project.
The Applicant has avoided and minimized impacts to the greatest extent practicable given the Project's purpose
and need. The proposed 24,935 square feet of stream buffer impacts are the result of the necessary
infrastructure and facility layout, without which, the Project goals would not be realized. This property has been
owned since January 1997 and its purchase was intended for this proposed Project. If the City cannot use the
existing property to consolidate the five divisions then the initial investment on the purchase of the property will
be lost, additional property will need to be purchased to relieve the additional space requirements needed at the
remote facilities, as well, the property cannot be used to consolidate multiple divisions in one location.
Logistically this will cause inefficiencies, create other impacts associated with the development of another
property that are significantly more than the proposed Project, and will not solve the original problems that were
the impetus of consolidating the divisions at one location. In order to provide adequate space for parking and
buildings, a minimum of 21 acres of buildable land is necessary. The southwestern portion of the site is
relatively narrow and is constrained by setbacks along the Interstate and wetlands to the north. A stream and
associated buffer bi-sect the property in this area and cannot be avoided.
An additional constraint to the site is the need to provide access for emergency vehicles in the event of a fire.
To comply with current IFC and local fire codes, pavement is proposed around the site, such that fire apparatus
vehicles have access to within 150 feet from all parts of the building. To comply with this requirement, impacts
to the buffer cannot be avoided. Offsite alternative sites were explored for this Project; however, in order to
provide adequate building space and parking for all divisions, at least 21 acres of buildable land are needed, as
well as an adjacent roadway infrastructure that supports heavy truck use. The current location allows for future
growth, provides better utilization of existing personnel and equipment, utilizes parts/tools warehousing and
non -duplication of housing parts, provides for better internal communication between divisions, and provides
protection of parked vehicles and equipment during flooding, which is now experienced at the current location of
the Public Works WSM Division, located southwest of this facility. In addition, the proposed layout provides
more acceptable storage and in-house work area conditions (e.g. dedicated pedestrian walkways), which
provides for a safer work environment for personnel, while utilizing the existing utility and road infrastructure.
Given the design constraints associated with a shared use facility (i.e. administration buildings, maintenance
warehouses, work vehicles, equipment storage) and the local zoning requirements, the applicant has minimized
impacts to the greatest extent practicable. Specifically, there is a setback associated with Interstate 85 along
the southern property boundary. This 50 foot setback limited useable space for parking and buildings along the
southern property line and pushed the development to the north, towards the stream and stream buffer.
Moreover, the southwestern portion of the property is bisected by a stream and buffer, and in order to provide
space for a building and parking, buffer impacts could not be avoided. The applicant explored the use of
retaining walls along the northern portion of the parking lot; however, this option provided very limited
avoidance, as space is still needed for parking and emergency vehicle access. Furthermore, most of the
vehicles and equipment being stored at the site are large construction vehicles and equipment, which required
more storage area than a passenger car or truck. Construction equipment and vehicles require more space to
maneuver (i.e. larger turning radii, larger parking areas, etc.), as well, when being serviced these vehicles
require large services bays, as well as additional areas with the lay down area for the large equipment (lifts,
hoists, cranes, etc.) needed to service the larger equipment. Therefore, the typical parking requirements for an
office building do not apply, and are considerably larger based on the type and number of pieces of equipment.
Approximately 368 parking spaces are required for the site. This includes parking for the visitors, employees,
and fleet vehicles (both large and small), as well as the additional handicap spaces required by the City
Ordinance. The original layout (Appendix D — Original Layout) proposed impacts to wetlands and a stream
channel in the northern portion of the property for an entrance road and the proposed fill slope for the parking
areas and pad sites extended into the wetlands in the central portion of the property. The layout was re-
designed, in order to avoid impacts to the wetlands and stream channel through the use of retaining walls. The
entrance road from Camden Avenue is a safety requirement, in order to provide safe ingress and egress, as
well as allow for multiple access points for emergency responders (i.e. fire, EMS, etc.). The road was re -located
in an area that avoids impacts to streams and wetlands. Moreover, stream impacts have been completely
avoided through the use of bridge. In addition, impacts to riparian buffers have been minimized to the maximum
extent practicable by aligning the bridge through the buffer as close to 90 degrees as possible. In an effort to
confine the entire facility for security purposes, a chain link fence is proposed, in which, small portions will be
constructed within the riparian buffer associated with Streams B and D resulting in minimal disturbance.

1 b Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Other measures taken to minimize impacts include the use of a suite of stormwater devices (e.g. underground
sand filters, underground detention, and filter strips) for stormwater treatment. This reduced the need for
detention ponds, which further reduced and minimized the impacts to the adjacent stream channels, wetlands,
and/or riparian buffers. A project-specific Erosion and Sediment Control (ESC) plan will be developed and
submitted to Durham for approval of the land disturbing activity. The ESC plan will be prepared in accordance
with the North Carolina Erosion & Sediment Control Laws and Regulations and the most current version of the
Erosion & Sediment Control Planning and Design Manual. The ESC plan will be approved by the locality prior
to any land-disturbing activity associated with the Project. All regulated land-disturbing activities associated with
the Project, including on- and off- site access roads, staging areas, borrow areas, stockpiles, and soil
intentionally transported from the Project Area will be covered by the project specific ESC plan. During
construction activities, the ESC Best Management Practices (BMPs) will be inspected and maintained
throughout the life of the construction activity providing for enhanced protection for the avoided jurisdictional
areas and further minimizing impacts to the aquatic resources. Measures will be taken to prevent oil, tar, trash,
debris and other pollutants from entering the adjacent jurisdictional streams and wetlands. Any excess
excavated materials not utilized as back fill will be placed and contained within upland areas and permanently
stabilized to prevent erosion into adjacent jurisdictional streams and wetlands. Therefore, stockpiling of
excavated material within jurisdictional streams and wetlands will be strictly prohibited as part of the
construction of this project. All project construction activities initiated within jurisdictional streams and wetlands
will be carried to completion in an expeditious manner to minimize the period of disturbance within the
jurisdictional streams and wetlands.

bank, permittee responsible riparian buffer restoration, payment into an approved in -lieu fee fund).
As noted in the submitted Riparian Buffer Variance Request, compensatory mitigation for the unavoidable
Riparian Buffer Impact B1 (Parking/Fire Lane) will be achieved through the purchase of off-site mitigation from a
mitigation bank, which is approved for use in the Neuse Watershed (HUC: 03020201). Buffer mitigation credits
will be purchased using the Standard Compensatory Mitigation Ratios at ratios of 3:1 for Zone 1 (39,249 SF) and
1.5:1 for Zone 2 (17,778 SF). This equates to a total compensatory mitigation obligation of 57,027 SF of buffer
credits. Credit availability letter from the North Fork Little River Buffer Bank, an approved wetland and stream
mitigation bank located in HUC 03020201, are attached.

2b Does this prosect require a Stormwater Manaqement Plan? X Yes
2c If this project DOES NOT require a Stormwater Management Plan, explain why:
2d If this project DOES require a Stormwater Management Plan, then provide a brief, narrative description of the
plan:
A suite of stormwater devices (e.g. underground sand filters, underground detention, and filter strips) for stormwater
treatment. This reduced the need for detention ponds, which further reduced and minimized the impacts to the
adjacent stream channels, wetlands, and/or riparian buffers. The site is located within the Upper Falls Lake
Watershed, Neuse River Basin. The proposed development will result in 34.6% total built upon area on the site. As
part of the development, peak stormwater discharges for the 1yr, 2yr and 10-24hr storm will be controlled to ensure
there is no increase in the peak stormwater discharge rates from the site. The SCS method of analysis was used for
the storm event calculations.
Total Disturbed acreage on the site is 21 -acres. Four underground sand filters, two underground detention systems,
and two level spreaders with filter strips are proposed for the treatment of the stormwater. There are stream buffers
surrounding the site, and careful planning has been utilized to avoid most of these buffer and stream impacts. The
proposed development will impact some areas of buffers and streams. No wetland impacts are planned for this
project. A bridge will be utilized in order to tie into Camden Avenue. The bridge will cross over the floodway and
Goose Creek while avoiding disturbance to the maximum extent possible. The site will also have floodplain impacts
which will be permitted through the City. There is no offsite upstream run-off entering the developed portion of the site.
Any upstream flow bypasses the site and remains in the buffered streams. Stormwater piping is proposed for this site
and measures have been taken such that all stormwater runoff leaves the subject property with no increase in peak
runoff.
Stormwater Quantity: One analysis point has been evaluated for compliance with stormwater ordinance labeled Point
'A'. Stormwater analysis point 'A' is located at the south property line. The runoff was analyzed to determine the
change in peak stormwater discharge rates for the 1 -yr, 2 -yr, 10 -yr and 100 -yr storm events. A summary of the design
calculations is provided below.
Stormwater Quality: By ordinance section 70-740, this project qualifies as a Redevelopment project, but we will treat
this project as new development. The Site is located in the Upper Falls Lake Basin where the minimum nutrient
removal requirements are 2.20-lbs/ac/yr of nitrogen and 0.33-lbs/ac/yr of phosphorous. In the Upper Falls Lake Basin
for new development, there is a 50% minimum of onsite nutrient treatment.

Page 2 of 2
Explanation: The stream(s) listed above has been located on the most recent published NRCS Soil Survey of
Durham County, North Carolina and/or the most recent copy of the USGS Topographic map at a 1:24,000 scale.
Each stream that is checked "Not Subject" has been determined to not be at least intermittent or is not present.
Streams that are checked "Subject" have been located on the property and possess characteristics that qualify it to be
at least an intermittent stream. There may be other streams located on the property that do not show up on the maps
referenced above but may be considered jurisdictional according to the US Army Corps of Engineers.
This on-site determination shall expire five (5) years from the date of this letter. Landowners or affected
parties that dispute a determination made by the DWR may request a determination by the Director. An
appeal request must be made within sixty (60) days of date of this letter. A request for a determination by the
Director shall be referred to the Director in writing. If sending via US Postal Service: c/o Karen Higgins;
DWR — 401 & Buffer Permitting Unit; 1617 Mail Service Center; Raleigh, NC 27699-1617. If sending via
delivery service (UPS, FedEx, etc.); Karen Higgins; DWR — 401 & Buffer Permitting Unit; 512 N. Salisbury
Street; Raleigh, NC 27604.
This determination is final and binding unless, as detailed above, unless an appeal is requested within sixty
(60) days.
This project may require a Section 404/401 Permit for the proposed activity. Any inquiries should be
directed to the US Army Corp of Engineers (Raleigh Regulatory Field Office) at (919)-554-4884.

EXECUTIVE SUMMARY
On behalf of the City of Durham — Department of Water Management (Applicant),
Timmons Group is submitting this Variance Request for the expansion of its Mist Lake Facilities
(Project). The proposed Project is situated on a 55 -acre parcel and consists of the construction
of two buildings totaling approximately 116,000 square feet: one to house the administration,
warehouse, and the other to hold the equipment maintenance shop, as well as appurtenant
facilities (utilities, stormwater, etc.).
The purpose of the proposed Project is to expand the existing facility at Mist Lake, in
order to accommodate multiple City of Durham Department of Water Management (DWM)
divisions and allow for potential moderate growth over the next 20 years. The DWM Mist Lake
Facilities Expansion project consists of two buildings totaling approximately 116,000 square
feet, which will consist of a building for the administration (which will provide office space for the
five divisions), and a warehouse, shops, and laydown area to store equipment when not in use
or undergoing repair for the maintenance division. The Project is consistent with the zoning
requirements for this area (IL - industrial) and is being undertaken to consolidate multiple
divisions that at present are located across Durham in one location, which will create cost,
logistical, and overall savings for the locality.
This property has been owned since January 1997, and its purchase was intended for
this proposed Project. If the City cannot use the existing property to consolidate the five
divisions then the initial investment on the purchase of the property will be lost, additional
property will need to be purchased to relieve the additional space requirements needed at the
remote facilities, as well, the property cannot be used to consolidate the multiple divisions in one
location. Logistically this will cause inefficiencies, create other impacts associated with the
development of another greenfield property that are significantly more than the proposed
Project, and will not solve the original problems that were the impetus of consolidating the
divisions at one location.
To accomplish the goals of the Project, impacts to the Riparian Buffer are unavoidable.
A total of area of 24,935 square feet (SF) of unavoidable permanent impacts to riparian buffer is
necessary (Zone 1 — 13,083, Zone 2 — 11,852SF).
These unavoidable impacts will be mitigated through the purchase of compensatory
buffer credits through an approved wetland mitigation bank. The total compensatory mitigation
proposed is 57,027 SF of buffer credits. The purchase of this compensatory mitigation will
ensure the unavoidable impacts proposed by the Project and will not result in a buffer loss that
will affect the water quality within the watershed.

2.0 INTRODUCTION
On behalf of the City of Durham — DWM (Applicant), Timmons Group is submitting this
Variance Request for the expansion of its Mist Lake Facilities (Project). The proposed Project is
situated on a 55 -acre parcel and consists of the construction of two buildings totaling
approximately 116,000 square feet: one to house the administration, warehouse, and the other
to hold the equipment maintenance shop, as well as appurtenant facilities (utilities, stormwater,
etc.).
3.0 SITE DESCRIPTION
3.1 Site Location
The site encompasses approximately 55 acres and is located at 1600 Mist Lake Drive, in
Durham County, North Carolina (see Figure 1: Vicinity Map). It is bound by 1-85 to the south,
an unnamed tributary to the west, and Camden Road to the north. The site is located within the
Neuse River Watershed (HUC 03020201) and entirely within the Piedmont Physiographic
Province.
The adjacent lands are composed of primarily industrial properties intermixed with
undeveloped land. The Project drains to unnamed tributaries, where surface waters enter into
Goose Creek. Surface waters from Goose Creek flow north to Ellerbee Creek before
discharging into Falls Lake, northeast of the Project.
A FEMA Flood Rate Insurance Map (FIRM) is included for review (Figure 2: FEMA FIRM
Map). The map shows that the Project area is located within an area identified as a X flood
zone. This designation by FEMA means the area is a minimal flood hazard, and is above the
500 -year flood level. Please note that a majority of the site has been designated as an "AE"
type flood zone with a 1% chance of annual flood hazard. The Project has been designed to
comply with applicable FEMA -approved state and local floodplain management requirements
and no increase in the 100 -year flood elevations is anticipated.
3.2 Site Conditions
The site currently houses several divisions of the DWM in a 20 -acre facility, along with
associated vehicles, equipment and inventory. The undeveloped areas, mainly along the
floodplain, are dominated by mid -successional mixed pine and hardwood forest with mixed
hardwoods adjacent to the drainage ways. The topography slopes gradually from the
southwestern corner to the north and east portion of the project limits.
The property was delineated by McAdams, during the Summer of 2017. Jason
Robinson, DWR, confirmed the Neuse Riparian Buffer locations on June 28, 2017, and a JD
request has been sent to Samantha Dailey, USACE. Documents pertaining to the wetland
delineation are provided in Appendix B: Wetland Delineation Information.
There are no wetlands, open water, stream and associated upland buffers within the
Project area that are under a deed restriction, conservation easement, restrictive covenant, or
other land use protective instrument.

4.0 PURPOSE AND NEED
The purpose of the proposed Project is to expand the existing facility at Mist Lake, in
order to accommodate multiple City of Durham DWM divisions and allows for potential growth
over the next 20 years. The Department of Water Management Mist Lake Facilities Expansion
project consists of two buildings totaling approximately 116,000 square feet: one to house the
administration, warehouse, and shops and the other to hold the equipment maintenance shop.
The Project is consistent with the zoning requirements for this area (IL - industrial) and is being
undertaken to consolidate multiple divisions at one location.
The DWM currently operates several of its divisions at 1600 Mist Lake Drive (North
Campus). This 20 -acre facility houses approximately 82 staff of the Administration, Plant
Engineering & Maintenance, Regulatory Compliance, and Utility Engineering divisions of the
Department, along with associated vehicles, equipment, and inventory. Currently, 145 DWM
Water & Sewer Maintenance (WSM) employees are co -housed at a second location on Martin
Luther King, Jr. Drive, the Public Works Operations Center (PWOC) along with Public Works
staff. The WSM workgroups at PWOC are responsible for Outfall Maintenance, Rehabilitation
Maintenance, Meter Reading, Meter Maintenance, Service Installations, and Mainline
Installations, along with the necessary vehicles, light and heavy equipment, and inventory to
maintain and operate approximately 2,600 miles (combined) of water and sewer mains, 8,148
hydrants, 25,896 water valves, and more than 83,000 water meters. The project will expand the
DWM Mist Lake facility to accommodate the relocation of the WSM Division from the PWOC
facility to the Mist Lake complex and potential growth over the next 20 years.
6.0 RIPARIAN BUFFER IMPACTS
To accomplish the goals of the Project, impacts to the Riparian Buffer are unavoidable.
The location of impacts to the Neuse Riparian Buffer are shown on the attached Impacts Map
(Figure 3: Mist Lake Facility Expansion — Buffer Impacts Map — Sheets 1 - 3). A jurisdictional
determination for this area will be provided under separate cover.
Therefore, to accomplish the goals of the Project, a total of area of 24,935 square feet (Zone 1 —
13,083, Zone 2 — 11,852SF) of unavoidable permanent impacts to riparian buffer is necessary.
The stormwater and utility plans are included in Appendix C: Preliminary Stormwater Plans.
7.0 DEMONSTRATION OF NEED FOR VARIANCE/AVOIDANCE AND MINIMIZATION
Impacts to jurisdictional features and buffers were avoided and minimized to the
maximum extent practicable by incorporating resourceful site planning, including the utilization
of the wetland delineation to adjust the layout to avoid and minimize impacts. Avoidance and
minimization were also accomplished during the design phase of the Project. The Applicant has
avoided and minimized impacts to greatest extent practicable given the Project's Purpose and
Need. The proposed 24,935 square feet of stream buffer impacts are the result of the
necessary infrastructure and facility layout, without which, the Project goals would not be
realized.

This property has been owned since January 1997 and its purchase was intended for
this proposed Project. If the City cannot use the existing property to consolidate the five
divisions then the initial investment on the purchase of the property will be lost, additional
property will need to be purchased to relieve the additional space requirements needed at the
remote facilities, as well, the property cannot be used to consolidate the multiple divisions in one
location. Logistically this will cause inefficiencies, create other impacts associated with the
development of another greenfield property that are significantly more than the proposed
Project, and will not solve the original problems that were the impetus of consolidating the
divisions at one location. In order to provide adequate space for parking and buildings, a
minimum of 21 acres of buildable land is necessary. The southwestern portion of the site is
relatively narrow and is constrained by setbacks along the Interstate and wetlands to the north.
A stream and its corresponding buffer bi-sect the property in this area and cannot be avoided.
An additional constraint to the site is the need to provide access for emergency vehicles
in the event of a fire. To comply with current IFC and local fire codes, pavement is proposed
around the site, such that fire apparatus vehicles have access to within 150 feet from all parts of
the building. To comply with this requirement, impacts to the buffer cannot be avoided.
Offsite alternative sites were explored for this Project; however, in order to provide
adequate building space and parking for all divisions, at least 21 acres of buildable land are
needed, as well as an adjacent roadway infrastructure that supports heavy truck use. The
current location allows for future growth, provides better utilization of existing personnel and
equipment, utilizes parts/tools warehousing and non -duplication of housing parts, provides for
better internal communication between divisions, and provides protection of parked vehicles and
equipment during flooding, which is now experienced at the current location of the Public Works
WSM Division, located southwest of this facility. In addition, the proposed layout provides more
acceptable storage and in-house work area conditions (e.g. dedicated pedestrian walkways),
which provides for a safer work environment for personnel, while utilizing the existing utility and
road infrastructure.
Given the design constraints associated with a shared use facility (i.e. administration
buildings, maintenance warehouses, work vehicles, equipment storage) and the local zoning
requirements, the applicant has minimized impacts to the greatest extent practicable.
Specifically, there is a setback associated with Interstate 85 along the southern property
boundary. This 50 -foot setback limited useable space for parking and buildings along the
southern property line and pushed the development to the north, towards the wetlands and
stream buffer. Moreover, the southwestern portion of the property is bisected by a
stream/buffer, and in order to provide space for a building and parking, buffer impacts could not
be avoided. The applicant explored the use of retaining walls along the northern portion of the
parking lot; however, this option provided very limited avoidance, as space is still needed for
parking and emergency vehicle access. Furthermore most of the vehicles and equipment being
stored at the site are large construction vehicles and equipment, which required more storage
area than a passenger car or truck. Construction equipment and vehicles require more space to
maneuver (i.e. larger turning radii, larger parking areas, etc.), as well, when being serviced
these vehicles require large services bays, as well as additional areas with the lay down area for
the large equipment (lifts, hoists, cranes, etc.) needed to service the larger equipment.
Therefore, the typical parking requirements for an office building do not apply, and are
considerably larger based on the type and number of pieces of equipment.

Approximately 368 parking spaces are required for the site. This includes parking for the
visitors, employees, and fleet vehicles (both large and small), as well as the additional handicap
spaces required by the City Ordinance.
The original layout (Appendix D — Original Layout) proposed additional impacts to the
wetlands and a stream channel in the northern portion of the property for an entrance road and
the proposed fill slope for the parking areas and pad sites extended into the wetlands in the
central portion of the property. The layout was re -designed, in order to avoid impacts to the
forested wetlands and stream channel through the use of retaining walls.
The entrance road from Camden Avenue is a safety requirement, in order to provide
safe ingress and egress, as well as allow for multiple access points for emergency responders
(i.e. fire, EMS, etc.). The road was re -located in an area that avoids impacts to streams and
wetlands. Moreover, stream impacts have been completely avoided through the use of a
bridge.
Other measures taken to minimize impacts include the use of a suite of stormwater
devices (e.g. underground sand filters, underground detention, and filter strips) for stormwater
treatment. This reduced the need for detention ponds, which further reduced and minimized the
impacts to the adjacent stream channels, wetlands, and/or riparian buffers.
A project -specific Erosion and Sediment Control (ESC) plan will be developed and
submitted to Durham for approval of the land disturbing activity. The ESC plan will be prepared
in accordance with the North Carolina Erosion & Sediment Control Laws and Regulations and
the most current version of the Erosion & Sediment Control Planning and Design Manual. The
ESC plan will be approved by the locality prior to any land -disturbing activity associated with the
Project. All regulated land -disturbing activities associated with the Project, including on- and off-
site access roads, staging areas, borrow areas, stockpiles, and soil intentionally transported
from the Project Area will be covered by the project specific ESC plan. During construction
activities, the ESC Best Management Practices (BMPs) will be inspected and maintained
throughout the life of the construction activity providing for enhanced protection for the avoided
jurisdictional areas and further minimizing impacts to the aquatic resources.
8.0 COMPENSATORY MITIGATION
Compensatory mitigation for these unavoidable impacts will be achieved through the purchase
of off-site mitigation credits from a mitigation bank, which is approved for use in the Neuse
Watershed (Hydrologic Unit Code 03020201). Buffer mitigation credits will be purchased using
the Standard Compensatory Mitigation Ratios at ratios of 3:1 for Zone 1 (39,249 SF) and 1.5:1
for Zone 2 (17,778 SF). This equates to a total compensatory mitigation obligation of 57,027 SF
of buffer credits. Credit availability letters from the North Fork Little River Buffer Bank an
approved wetland and stream mitigation bank located in HUC 03020201, are located in
Appendix E: Compensatory Mitigation Documents.

B. Proposed Activity
1. Project Description
1a. Provide a detailed description of the proposed activity including its purpose:
The purpose of the proposed project is to expand the existing facility at Mist Lake, in order to accommodate multiple City of
Durham Department of Water Management (DWM) divisions and allow for potential moderate growth over the next 20
years. The DWM Mist Lake Facility Expansion prosect consists of two buildings totaling approximately 116,000 square feet,
which will consist of a building for the administration (which will provide office space for the five divisions), a warehouse,
shops, and laydown area to store equipment when not in use or undergoing repair for the maintenance division. The
project is consistent with the zoning requirements for this area (IL - industrial) and is being undertaken to consolidate
multiple divisions that at present are located across Durham in one location, which will create cost, logistical, and overall
savings for the locality.
TheDWM currently operates several of its divisions at 1600 Mist Lake Drive (North Campus). This 20 -acre facility houses
approximately 82 staff of the Administration, Plant Engineering & Maintenance, Regulatory Compliance, and Utility
Engineering divisions of the Department, along with associated vehicles, equipment, and inventory. Currently, 145 DWM
Water & Sewer Maintenance (WSM) employees are co -housed at a second location on Martin Luther King, Jr. Drive, the
Public Works Operations Center (PWOC) along with Public Works staff. The WSM workgroups at PWOC are responsible for
Outfall Maintenance, Rehabilitation Maintenance, Meter Reading, Meter Maintenance, Service Installations, and Mainline
Installations, along with the necessary vehicles, light and heavy equipment, and inventory to maintain and operate
approximately 2,600 miles (combined) of water and sewer mains, 8,148 hydrants, 25,896 water valves, and more than
83,000 water meters. The prosect will expand the DWM Mist Lake facility to accommodate the relocation of the WSM
Division from the PWOC facility to the Mist Lake complex and potential growth over the next 20 years, without additional
impacts.

2b. Attach a Supplement Form for each structural BMP proposed.
2c. Attach an Operation and Maintenance (O&M) Form for each structural BMP proposed.
E. Demonstration of Need for a Variance
The variance provision of the riparian buffer rules allows the Division or the Environmental Management Commission to grant a
variance when there are practical difficulties or unnecessary hardships that prevent compliance with the strict letter of riparian
buffer protection.
1. Explain how complying with the provisions of the applicable rule would prevent you from securing a reasonable return from or
make reasonable use of your property. Merely proving that the variance would permit a greater profit from the property shall
not be considered adequate justification for a variance. The Division will consider whether the variance is the minimum possible
deviation from the terms of the applicable Buffer Rule that shall make reasonable use of the property possible.
In order to provide adequate space for parking and buildings, a minimum of 21 acres of buildable land is necessary. The
southwestern portion of the site is relatively narrow and is constrained by setbacks along the Interstate and wetlands to the
north. A stream and its corresponding buffer bi-sect the property in this area and cannot be avoided. This property has been
owned prior to Julv 1997. and its current and or000sed use was intended for this oroiect. If the Citv cannot use the existine
FORM: VAR 10-2013 Page 5 of 7

propertV to consolidate the five divisions then the initial investment on the purchase of the property will be lost, additional
Property will need to be purchased to relieve the additional space requirements needed at the remote facilities, as well, the
propertV cannot be used to consolidate the multiple divisions in one location. Logistically this will cause inefficiencies, create
other impacts associated with the development of another greenfield propertV that are significantly more than the proposed
project, and will not solve the original problems that were the impetus of consolidating the divisions at one location.
2. Explain how the hardship results from application of the Buffer Rule to the property rather from other factors such as deed
restrictions or other hardships (e.g. zoning setbacks, floodplains, etc).
Given the design constraints associated with a shared use facility (i.e. administration buildings, maintenance warehouses, work
vehicles, equipment storage) and the local zoning requirements, the applicant has minimized impacts to the greatest extent
practicable. Specifically, there is a setback associated with Interstate 85 along the southern property boundary. This 50 -foot
setback limited useable space for parking and buildings along the southern propertV line and pushed the development to the
north. towards the wetlands and stream buffer. Moreover. the southwestern portion of the oroperty is bisected by a
stream/buffer, and in order to provide space for a building and parking, buffer impacts could not be avoided. The applicant
explored the use of retaining walls along the northern portion of the parking lot; however, this option provided very limited
avoidance, as space is still needed for parking and emergency vehicle access; furthermore, most of the vehicles and equipment
being stored at the site are large construction vehicles and equipment, which required more storage area than a passenger car
or truck. Construction equipment and vehicles require more space to maneuver (i.e. larger turning radii, larger parking areas,
etc.). When being serviced these vehicles require large services bays, as well as additional areas with the lay down area for the
large equipment (lifts, hoists, cranes, etc.) needed to service the larger equipment. Therefore, the typical parking requirements
for an office building do not apply, and are considerably larger based on the type and number of pieces of equipment.
proposed additional impacts to the wetlands in the northern portion of the propertV, associated with roadways. However, the
layout was re -designed, in order to avoid impacts to the forested wetlands and buffers within the central portion of the
propertV.
3. Explain how the hardship results from physical nature of the property, such as its size, shape, or topography, which is different
from that of neighboring property.
As stated above, the southwestern portion of the propertV is narrow and constrained by an interstate to the south and wetlands
and stream channels to the north and west. A stream channel bi-sects the propertV in this location and cannot be avoided in
order to access the uplands on either side of the channel. Additional hardships include steep slopes, floodplain, and wetlands
abutting the project, which severely impact the amount of developable area. In order to provide access for emergency vehicles,
Local Fire Code requires a paved roadway around the buildings, which will allow fire apparatus vehicles within a minimum of
150 feet of anv portion of the buildine.
Offsite alternative sites were explored for this project; however, in order to provide adequate building space and parking for all
divisions, at least 21 acres of buildable land are needed, as well as an adjacent roadway infrastructure that supports heavy truck
use. The current location allows for future growth, provides better utilization of existing personnel and equipment, utilizes
parts/tools warehousing and non -duplication of housing parts, provides for better internal communication between divisions,
and provides protection of parked vehicles and equipment during flooding, which is now experienced at the current location of
the Public Works WSM Division, southwest of this site. In addition, the proposed layout provides more acceptable storage and
in-house work area conditions. and dedicated pedestrian walkways. which provides for a safer work environment for personnel.
while utilizing the existing utility and road infrastructure.
4. Explain whether the hardship was caused by the applicant knowingly or unknowingly violating the applicable Buffer Rule.
The applicant has not violated the buffer rules.
5. For Neuse, Tar -Pamlico, Jordan Lake and Goose Creek only: Did the applicant purchase the property after the effective date of
the applicable Buffer Rule and then request a variance?
No — the applicant purchased the property in January 1997, prior to the effective date of the Buffer Rules. However, a
portion of the project does extend into land purchased in 2016.
FORM: VAR 10-2013 Page 6 of 7

6. Explain how the hardship is rare or unique to the applicant's property, rather than the result of conditions that are widespread.
The subiect property was Purchased iJanuary 1997 prior to the implementation of the buffer I s There is an exist' 20 -
acre facility that houses approximately82 staff of the Administration, Plant Engmeeringg, Maintenance, Regulatory Compliant
and Utility En¢ need ng divisions of the Department alone with associated vehicles equipment and inventory. The applicant

Dear Todd:
Wildlands Holdings III, LLC currently has sufficient riparian Buffer credits from the North Fork Little River Nutrient Offset

credits will be sold on a first come, first serve basis. An invoice for this transaction will be sent upon your request and
we will formally reserve both the credits and price quoted for a period of 30 days from the invoice.
Final transfer of the credits will be made upon receipt of a copy of the 401 Water Quality Certification Authorization
Certificate from the NC Department of Environmental Quality approving the Riparian Buffer mitigation purchase from
the Bank and upon receipt of your payment to Wildlands Holding III, LLC. We will then issue a credit transfer certificate
verifying your credit purchase to the North Carolina Division of Water Resources and to you for your records
We appreciate the opportunity to assist you with your mitigation requirements. Please contact me at 704-719-2100 or
