SUBJECT: Response to December 22, 2015 Request for More Information letter for the Proposed
Addition of High Occupancy Toll (HOT) Lanes, and the Conversion of Existing High Occupancy
Vehicular (HOV) Lanes to HOT lanes on approximately 26 Miles of Existing I-77 from I-277
(Brookshire Freeway — Exit 11) in Mecklenburg County to Exit 36 /NC 150 (Iredell County) and
along I-277 from I-77 southward to North Brevard Street.
Reference: US Army Corps of Engineers (USACE) Request for Information, dated December 22, 2015
NCDOT 404 & 401 Application dated September 9, 2015
Dear Ms. Amschler:
The North Carolina Department of Transportation (NCDOT) is in receipt of the above referenced letter and is
providing the following response to the requested information.
JUSTIFICATION FOR MANAGED LANES (Optional toll lanes)
According to the North Carolina Statewide Transportation Plan adopted by the Board of Transportation in
August 2012, North Carolina will need at least $94.1 billion (in 2011 dollars) between today and 2040 just to
maintain existing physical conditions and levels of congestion and mobility for all elements of the state's
transportation system, and $122.8 billion to improve the transportation network's performance and capacity
to desired conditions.
To maintain existing conditions, the State will need to fnd new revenue sources to generate $32.3 billion in
additional funding between now and 2040.
Growth and congestion compound these issues. The Charlotte Region's urban population has increased 135
percent in the past 25 years alone, making it the 43rd largest urban area in the nation. More people moving
to the area mean more vehicles on the roadway. In particular, traffic on I-77 between I-85 and Iredell
County has jumped more than 20 percent in the past five years, creating a congested commute for drivers,
especially during peak travel times.
Due to traditional funding limitations and recognized financial constraints, alternative project financing
options were considered for this project.

The project's purpose and need is consistent with the financial objective identified in CRTPO's 2035 LRTP
which states to "Make investment decisions for transpoi•tation modes that make the most efficient use of
limited public resources". This includes actively exploring new sources of revenue and to foster innovative
financing and partnership opportunities for project development and implementation. Market soundings and
Traffic and Revenue Studies support the decision to pursue two managed lanes in the southern and central
portions of the project.
ALTERNATIVE SELECTED
In an email sent to the USACE on December 17t", and subsequent conversations, several operational topics
were provided in support of Alternative 2 as well as the financial and commec•cial benefits of selecting
Alternative 2 as the Preferred Alternative. These benefits and support are pt•ovided in greater detail below.
The purpose of the proposed action is to provide immediate travel time reliability along I-77 from Uptown
Charlotte to the Lake Norman area. Because the project is designed to address an immediate need, the
opening and design years are both proposed for 2017. However, the managed lanes will ensure travel time
reliability well past the 2017 design year. Travel time reliability is defned as maintaining the FHWA
mandate for a minimum 45 mph within these managed lanes. In addition, the extension of managed lanes to
more sections of I-77 will further the Local/Regional Planning Organization's goal to establish programs and
incentives that encourage ridesharing and enhanced bus transit services.
The analysis of a No-Build Alternative is required under the National Environmental Policy Act (NEPA) and
serves as a benchmark against which the impacts of other alternatives can be compared. The No-Build
Alternative represents the I-77 corridor without the proposed project. Under the No-Build Alternative, the
only improvements that could have been made to I-77 within the project limits through the design year 2017
would have been the widening of existing lanes and shoulders of I-77 southbound between I-277 (Brookshire
Freeway) and I-85 as STIP Project I-3311E. Table 4 of the FONSI (Table 3-3 of EA) provides average 2017
Peak Period speeds. However, it must be noted that these speeds are averaged over the entire 26 mile project
corridor. 2017 Average Peak Period speeds for specific segments of the project are detailed in Tables 3, 4, 5,
6, 7 and 8 of the Atkins September 2013 Addendum to Traffc Operations Technical Memorandum
(Appendix A) This greater level of detail demonstrates significantly lower performance for the No Build
Alternative when compared to the Build Alternatives. In addition to better results, HOT lane performance is
guaranteed at a minimum 45 miles per hour. Average speeds for general purpose lanes (No Build) are not
guaranteed or reliable. The No-Build Alternative does not meet the project's purpose to provide immediate
travel time reliability along the corridor and particularly along the corridor's most congested segments.
Traffc analyses (Traffic Estimate Technical Memorandum — RK&K, June 2013* and Supplement — Atkins,
June 2013'�; as well as Traffic Operations Tech Memo — Atkins, July 2013*, and Addendum — Atkins,
September 2013*) showed that Alternative 3 would not improve travel time reliability along northbound I-
77, south of I-85. In addition, the conversion of the existing HOV lane in the southbound direction of I-77
south of I-85 to a managed lane increases the volume of users in this lane. With no direct connection to
I-277 more vehicles would have to weave across the general purpose lanes to exit onto I-277/NC 16
reducing the capacity and the travel time reliability in the general purpose lanes.
Both Alternative 1 and 2 add HOT lane capacity along the entirety of the project and include a direct
connection to I-277. However, Alternative 2 adds a second HOT lane in each direction between I-277
(Brookshire Freeway - Exit 11) and I-85 (Exit 13) for a total of two HOT lanes in each direction from I-277
(Brookshire Freeway-Exit 11) to West Catawba Avenue (Exit 28) and one HOT lane in each direction
between West Catawba Avenue (Exit 28) and NC 150 (Exit 36).
To ensure maintaining the minimum 45 mph reliable travel time criteria, VISSIM traffic flow model
simulations constrains individual managed lane capacity at 1400 veh/hr/lane. This ensures that the model
2

run, regardless of number of managed lanes, will meet the reliable trip time definition for the managed lanes.
Anything over the 1400 veh/hr/lane is simulated to be placed back into, or remain in, the general purpose
lanes. In reality, this would be achieved by increasing toll rates to keep managed lane traffic to the mandated
threshold, essentially rendering additional demand for the managed lanes unmet. More traffic using the
general purpose lanes reduces overall throughput or Vehicle Miles Traveled (VMT) for the corridor and does
not relieve the existing traffic problems identified in the purpose and need. Additionally the traffic models
do not account for what happens when an accident occurs in a single managed lane, therefore negating travel
time reliability for all users, including transit buses.
The traffic analyses provided in the Traffic Estimate Technical Memorandum (RK&K - June, 2013*) and its
supplement (Atkins - June, 2013*) modeled Traffic Volume Estimates during 2017 Peak Hour and Peak
Periods for Alternatives 1 and 2. Analyses show the projected demand for the additional HOT lane provided
with Alternative 2 at the southern end of the project is greater than the capacity of one managed lane used
in this analysis (1,400 veh/hr/lane). Northbound PM Peak Period demand has an additional 2,335 users and
Southbound AM Peak Period has an additional 2,165 users when compared to the single lane alternative
(Alternative 1). Peak Hour calculations show corresponding demands with an additional 920 users
Northbound PM and an additional 840 users Southbound AM (see Appendix B, Figures 1, 1B, 2, and 2B).
The additional managed lane provided in Alternative 2 results in satisfying the greater demand for the
managed lanes, moving more vehicles not only along the managed lanes, but improving overall capacity
through the project area.
ADDITIONAL INFORMATION TO SUPPORT THE ALTERNATNE SELECTED
NCDOT also took into consideration the crash history along this cor•ridor. In the Final Traffic Operations
Technical Memo (July 2013)* a crash analysis was performed to compare crash rates within the study area to
other urban inteestates in North Carolina. This analysis also determined the types of crashes and identified
crash hot spots. A Tcaffic Engineering Accident Analysis System's Strip Analysis Report was used to
evaluate the existing crash rates on the I-77 mainline between milepost 10 and milepost 36 and the I-277/ NC
16 mainline (Brookshire Freeway) fi•om Beatties Ford Road to Caldwell Street. Five years of crash history,
from lanuai•y 1, 2008 to December 31, 2012, was analyzed. Ducing the five-year ceporting period, there
were a total of 4,392 crashes within the I-77 corridor and 726 crashes within the I-277 corridor. This equates
to 2.4 crashes occut•ring a day along the I-77 project limits. In addition, it was found that I-77 and I-277 have
a substantially higher rate of total crashes than the average rate for• all No��th Carolina urban interstates. Rear
end and sideswipe crashes make up over two-tl�irds of the total crashes on I-77 and over three-quarters of the
total crashes on I-277/ NC 16. Rear end crashes are typically caused by slowing down due to congestion.
Sideswipe crashes are related to lane change maneuvers typically at interchanges. Traffic operations would
clearly be more volatile due potential breakdowns oi• accidei�ts associated with 1 mallaged lane in each
direction along a corridor which has alt•eady has substantially higher rate of total crashes than the average
rate for all North Carolina urban interstates. Accommodating higher vehicle throughput also reduces the t•isk
of operational breakdown thereby increasing travel time reliabilities.

MITIGATION FOR THE NORTH AND SOUTH SECT[ONS
In a letter dated December 4, 2015, the NC Division of Mitigation Services (NCDMS) has committed to
implement suffcient compensatory stream and riparian wetland mitigation credits to offset the impacts
associated with this project as determined by the regulatory agencies.
NCDOT proposes 2:1 mitigation on all streams and wetlands, with the exception of Irwin Creek, Dillions
Twin Lakes, and Lake Jo (stream impacts). NCDOT proposes a mitigation of 0.25 to 1 since these systems
are significantly degraded by previous relocation, urbanization, and proximity to adjacent highway facilities.
No room exists for onsite mitigation to be practicable. The low mitigation ratio considers the likelihood of
out-of-HUC mitigation due to limited assets in the Lower Catawba River Basin (per policy approved by the
IRT on September 17, 2015), meaning mitigation quantities in this HUC are doubled.
NC SAM forms were completed at three points along Irwin Creek and Dillons Twin Lakes & Lake Jo
documenting the above mentioned degradation and subsequent request for a lower mitigation ratio. This
information is included in Appendix C.
JURISDICTIONAL DETERMINATION FOR THE NORTH SECTION
This information was provided to the Corps via email on Friday, December 18, 2015, but is also included in
Appendix D.
TORRENCE CREEK STREAM RESTORATION SITE
Please find the documents listed below in Appendix E:
- The Conservation Easement Declaration,
- Deed for the Mitigation Site (which references the tract "thence running with the westerly
right-of-way of Interstate 77")
- Drawings which display the referenced right-of-way boundary as well as the location of the
pedestrian culvert to documend display no impacts to the mitigation site.
- A revised impact summary table to display the additional temporary impacts (182 feet, all
within NCDOT right-of-way) to a UT to Torrence creek necessary for construction access to
construct the pedestrian culvert.
Thank you for your time and assistance with this project. Please contact Michael Turchy at either

❑ Office (Desk) Determination. Date:
� Field Determination. Date(s): August 8, 2012

1. The Corps of Engineers believes that there may be jurisdictional waters of the United States
on the subject site, and the permit applicant or other affected party who requested this
preliminary JD is hereby advised of his or her option to request and obtain an approved
jurisdictional determination (JD) for that site. Nevertheless, the permit applicant or other person
who requested this preliminary JD has declined to exercise the option to obtain an approved JD
in this instance and at this time.
2. In any circumstance where a permit applicant obtains an individual permit, or a Nationwide
General Permit (NWP) or other general permit verification requiring "pre-construction
notification" (PCN), or requests verification for a non-reporting NWP or other general permit, and
the permit applicant has not requested an approved JD for the activity, the permit applicant is
hereby made aware of the following: (1) the permit applicant has elected to seek a permit
authorization based on a preliminary JD, which does not make an official determination of
jurisdictional waters; (2) that the applicant has the option to request an approved JD before
accepting the terms and conditions of the permit authorization, and that basing a permit
authorization on an approved JD could possibly result in less compensatory mitigation being
required or different special conditions; (3) that the applicant has the right to request an
individual permit rather than accepting the terms and conditions of the NWP or other general
permit authorization; (4) that the applicant can accept a permit authorization and thereby agree
to comply with all the terms and conditions of that permit, including whatever mitigation
requirements the Corps has determined to be necessary; (5) that undertaking any activity in
reliance upon the subject permit authorization without requesting an approved JD constitutes
the applicant's acceptance of the use of the preliminary JD, but that either form of JD will be
processed as soon as is practicable; (6) accepting a permit authorization (e.g., signing a
proffered individual permit) or undertaking any activity in reliance on any form of Corps permit
authorization based on a preliminary JD constitutes agreement that all wetlands and other water
bodies on the site affected in any way by that activity are jurisdictional waters of the United
States, and precludes any challenge to such jurisdiction in any administrative or judicial
compliance or enforcement action, or in any administrative appeal or in any Federal court; and
(7) whether the applicant elects to use either an approved JD or a preliminary JD, that JD will
be processed as soon as is practicable. Further, an approved JD, a proffered individual permit
(and all terms and conditions contained therein), or individual permit denial can be
administratively appealed pursuant to 33 C.F.R. Part 331, and that in any administrative appeal,
jurisdictional issues can be raised (see 33 C.F.R. 331.5(a)(2)). If, during that administrative
appeal, it becomes necessary to make an official determination whether CWA jurisdiction exists
over a site, or to provide an official delineation of jurisdictional waters on the site, the Corps will
provide an approved JD to accomplish that result, as soon as is practicable.
This preliminary JD finds that there "may be"waters of the United States on the subject project
site, and identifies all aquatic features on the site that could be affected by the proposed activity,
based on the following information:

to each characteristic with'tn the range shawn fox the ecorsgion. Page 3 provides a brief description of how to review the
characteristics identified in the worksheet. 5cores should reflect an overa➢1 assessn�ent of the streabn xeac� under evaluation. If a
characteristic cannot be evaluated due to site or weatl�er conditions, enter 0 in the scoring box and pravide an e�lanation in khe
comn�ent section. Wh�re there are obvious changes in t]�e cl�aracter of a stream u�der review {e.g., the streaan flows from a past�e
�to a faa-est), the stream may be d�vided into smaller rea�hes that display m�re contir�uity, and a separate forzn used to evaluate each
reach. ihe total score assi�ned to a stream reach must range betvreen 0 and 100, wi�h a score of lOQ representing a streaa�a of the
