Introduction
The intention of this technical memorandum is to provide revised results for Phase
2B(1) from the originally submitted addendum dated October 2, 2018. This analysis will
include an additional egress for the development onto Carolina Beach Road north of
Sanders Road. The proposed land use size will be adjusted appropriately to
demonstrate the number of units that will be able to be supported by the already
approved improvements on Manassas Drive and the additional proposed egress on
Carolina Beach Road. Since the proposed land use size is between the Phase 2B(1)
and Phase 2B submitted in the TIA, this new/additional phase will be labeled Phase
2B(2). Both revised and additional phase build year were assumed to be 2020. The new
distribution for Phase 2B(2) used is similar to that of Phase 2B(1) with a change to add
traffic flow to the additional egress.
Trip Generation
Trips for Phase 2B(1) were projected using TripGen10 software, based on the 10th
edition of the ITE Trip Generation Manual. Table 1 presents the results.

Trip Distribution
Site trips for Phase 2B(1) and Phase 2B(2) were distributed based on the previously
approved Phase 2B(1) distribution, with a small change to add traffic flow to the
additional egress in Phase 2B(2). Distribution for Phase 2B(1) is shown in Figure A1
and distribution for Phase 2B(2) is shown in Figure A2, and the directional distributions
for site trips are as follows:
75% to and from the north on US 421 (Carolina Beach Road)
20% to and from the south on US 421 (Carolina Beach Road)
5% to and from the west on Sanders Road
2020 Phase 2B(1) Total Traffic
The 2020 Phase 2B(1) total traffic volumes were obtained by summing 2020 future no
build volumes (Figure B) and site trips due to the proposed development. Site trips are
shown in Figure C. The 2020 Phase 2B(1) build volumes are shown for the AM and PM
peaks in Figure D.
2020 Phase 2B(2) Total Traffic
The 2020 Phase 2B(2) total traffic volumes were obtained by summing 2020 future no
build volumes (Figure B) and site trips due to the proposed development. Site trips are
shown in Figure E. The 2020 Phase 2B(2) build volumes are shown for the AM and PM
peaks in Figure F.

Discussion of Results
The following section discusses the Phase 2B(1) Build and Phase 2B(2) Build level of
service for each intersection.
US 421 (Carolina Beach Road) at Sanders Road
This signalized intersection is expected to operate at LOS D in both the AM and PM
peaks in 2020 future no build conditions. In 2020 Phase 2B(1) build conditions, it is
expected to operate at LOS D in the AM peak and LOS E in the PM peak. In 2020
Phase 2B(2) build conditions, LOS is expected to remain unchanged. While LOS E is
not ideal, this delay increase is within the 25% increase permitted by the congestion
management guidelines. This site is mostly adding through traffic to the signal and is
not expected to critically increase delay and queueing at the intersection. Additionally,
the traffic model included fully protected phasing for the northbound and southbound left
turns as required by congestion management standards, which generates conservative
analysis results. Therefore, with Phase 2B(1) recommendations in place, no additional
improvements are needed in Phase 2B(2).

US 421 (Carolina Beach Road) at Manassas Drive
This signalized intersection is expected to operate at LOS B during both the AM and PM
peak hours in 2020 future no build conditions. In 2020 Phase 2B(1) Build conditions with
improvements, LOS C is expected in the AM peak and LOS B in the PM peak. In 2020
Phase 2B(2) Build conditions with the additional egress, LOS is expected to remain
unchanged. Therefore, with Phase 2B(1) recommendations in place, no additional
improvements are recommended for Phase 2B(2).

US 421 (Carolina Beach Road) at Autumn Care Nursing Home
This unsignalized intersection is expected to operate at LOS C in both the AM and PM
peaks in 2020 future no build conditions. In 2020 Phase 2B(1) build conditions, it is
expected to operate at LOS D in the AM peak and LOS C in the PM peak. In 2020
Phase 2B(2) build conditions, LOS is expected to remain unchanged. While a drop in
LOS is not ideal, this delay increase is within the 25% increase permitted by the
congestion management guidelines. This site is mostly adding through traffic to the
intersection and is not expected to critically increase delay and queueing at the U-turns.
Therefore, no improvements are recommended for either phase.

US 421 (Carolina Beach Road) at Site Access (Egress Only)
This site access is proposed to be stop-controlled egress only access. In 2020 Phase
2B(2), LOS is expected to operate at LOS E during the AM peak and LOS C during the
PM peak. While LOS E is not ideal, this is typical for stop-controlled movements
entering a major roadway such as US 421. The delay is expected to be short-lived and
no queuing issues are expected based upon the analysis results. Therefore, it is
recommended to design the site access according to NCDOT standards.

Summary and Conclusion
The intention of this addendum revision is to provide revised results for Phase 2B(1)
from the originally submitted addendum dated October 2, 2018. This analysis will
include an additional egress for the development onto Carolina Beach Road north of
Sanders Road. The proposed land use size was adjusted appropriately to demonstrate
the number of units that will be able to be supported by the already approved
improvements on Manassas Drive and the additional egress on Carolina Beach Road.
Since the proposed land use size is between the Phase 2B(1) and Phase 2B submitted
in the TIA, this new/additional phase will be labeled Phase 2B(2). Both revised and
additional phase build year were assumed to be 2020. The new distribution for Phase
2B(2) used is similar to that of Phase 2B(1) with a change to add traffic flow to the
additional egress.
Based on the analysis, with the approved improvements in place, Phase 2B(1) will
support up to 219 single family homes and 398 townhomes for a total of 617 dwelling
units. By providing the proposed egress, an additional 60 dwelling units of townhomes
can be sustained within Phase 2 of the development. Therefore, with Phase 2B(1)
recommendations in place, no additional improvements are needed to accommodate
Phase 2B(2).
In conclusion, this study has reviewed the impacts of both background traffic along with
the Phase 2B(1) and Phase 2B(2) development traffic, and has determined that with the
recommended improvements in place that there will be adequate capacity to
accommodate future traffic. Please note that all accesses to the site are required to be
constructed to NCDOT standards.
