Trinity Landing – Transportation Impact Analysis
Prepared for Lutheran Services Carolinas
New Hanover County, NC
April 7, 2017
1.0 Introduction
The proposed Trinity Landing development is to be located on Masonboro Loop Road in
New Hanover County, North Carolina. The development is planned to consist of 220
senior adult housing dwelling units and amenities including a 7,350 square foot
restaurant, a 2,150 square foot convenience market, a 900 square foot beauty spa, and
a 6,900 square foot wellness center. The development will utilize one (1) access point
on Masonboro Loop Road. Figure 1 presents the preliminary site plan. Figures 2A and
2B show the site location map and vicinity map, respectively.
DAVENPORT was retained to determine the potential traffic impacts of
this development and to identify transportation improvements that may be required to
accommodate the impacts of both background traffic and new development traffic. The
following intersections were included in the study:
Masonboro Loop Road at Trailing Vine Lane
Per coordination with the WMPO, two development scenarios were
analyzed in this study: one with amenities open to the public, and the other
with the amenities open to the Lutheran Services Carolinas community,
their residents, and their guests. The above-mentioned intersection was
analyzed for the following scenarios:
• 2017 Existing Conditions
• 2020 Future No Build Conditions
• 2020 Future Build-Out Conditions with amenities Open to the Public
• 2020 Future Build-Out Conditions with amenities open to the Lutheran Services
Carolinas community, their residents, and their guests
• 2020 Future Build-Out with Improvements (as necessary)
The build-out analysis year for this project was assumed to be 2020. The AM (7 am –
9 am) and PM (4 pm – 6 pm) weekday peaks were studied.
The WMPO, County, and North Carolina Department of Transportation (NCDOT) were
contacted to obtain background information and to ascertain the elements to be
covered in this Transportation Impact Analysis (TIA). Information regarding the property
was provided by Lutheran Services Carolinas.

3.0 Approved Developments and Committed Improvements
3.1 Approved Developments
Approved developments are developments that have been recently approved in
the area, but not yet constructed. Per the WMPO, County, and NCDOT staff, there are
no approved developments in the vicinity of this project. However, a 1% annual growth
rate was applied to account for any growth in the area.
3.2 Committed Improvements
Committed Improvements are improvements that are planned by NCDOT, a local
municipality, or a developer in the area, but not yet constructed. Per the WMPO,
County, and NCDOT staff, there are no committed improvements in the vicinity of this
project.
4.0 Methodology
4.1 Base Assumptions and Standards
In general, the analysis for this project was conducted utilizing commonly accepted
NCDOT standards. The following table contains a summary of the base assumptions:
Table 4.1 - Assumptions
Peak Hour Factor 0.90
Background Traffic Annual Growth Rate 1.0% per year for all roadways
Base Signal Timing/Phasing Provided by NCDOT
Analysis Software Synchro/SimTraffic Version 9.0
Lane widths 12-feet
Truck percentages 2%
4.2 Trip Generation
The proposed development is planned to consist of 220 senior adult housing dwelling
units and amenities including a 7,350 square foot restaurant, a 2,150 square foot
convenience market, a 900 square foot beauty spa, and a 6,900 square foot wellness
center. Per coordination with the WMPO, two development scenarios were analyzed in
this study: one with amenities open to the public, and the other with amenities open to
the Lutheran Services Carolinas community, their residents, and their guests. Tables
4.2 and 4.3 provide trip generation estimates for each of these conditions. The
projected trip generation potential of the current land use was computed using TripGen
2013 software, based on the 9th Edition of ITE Trip Generation Manual.

4.3 Trip Distribution
Site trips for this proposed development were distributed based on the existing traffic
patterns and engineering judgment. The directional distributions for the primary site
trips are as follows, with the amenity uses open to the public:
• 50% to and from the north on Masonboro Loop Road
• 50% to and from the south on Masonboro Loop Road
The directional distributions for the primary site trips are as follows, with the amenity
uses not open to the public:
• 40% to and from the north on Masonboro Loop Road
• 60% to and from the south on Masonboro Loop Road
The directional distributions for the pass-by site trips are as follows, only with the
amenity uses open to the public:
• 50% to and from the north on Masonboro Loop Road
• 50% to and from the south on Masonboro Loop Road
The site trip distributions are shown in Figures 5A and 5C, and the pass-by
distribution is shown in Figure 5B.
4.4 Future No Build Traffic
The 2020 future no build traffic volumes were computed by applying a 1.0%
compounded annual growth rate to the 2017 existing traffic volumes. Figure 6
shows the 2020 future no build traffic volumes for AM and PM peaks.
4.5 Total Traffic with Amenity Uses Open to the Public
The 2020 build-out traffic volumes were obtained by summing 2020 future no build
volumes and site trips due to the proposed project. Site trips are shown in Figure 7A
and Pass-By trips are show in Figure 7B. The resulting build volume totals for AM and
PM peaks are shown in Figure 8.
4.6 Total Traffic with Amenity Uses NOT Open to the Public

04/07/2016 160273 Trinity Landing – Transportation Impact Analysis 21
5.0 Capacity Analysis
5.1 Level of Service Evaluation Criteria
The Transportation Research Board’s Highway Capacity Manual (HCM) utilizes a term
“level of service” to measure how traffic operates in intersections and on roadway
segments. There are currently six levels of service ranging from A to F. Level of
service “A” represents the best conditions and Level of Service “F” represents the worst.
Synchro Traffic Modeling software was used to determine the level of service for studied
intersections. All worksheet reports from the analyses can be found in the Appendix.
Table 5.1 – Highway Capacity Manual

04/07/2016 160273 Trinity Landing – Transportation Impact Analysis 22
5.2 Level of Service Results
The results of the study are discussed by intersection below:
Masonboro Loop Road at Trailing Vine Lane
The eastbound approach of this unsignalized intersection currently operates at LOS C
in the AM and PM peaks. In 2020 future no build conditions, it is expected to remain
unchanged.
With the addition of site traffic, with amenity uses open to the public, the westbound
approach is projected to operate at LOS F in the AM peak and LOS E in the PM peak.
With the addition of site traffic, with amenity uses NOT open to the public, this
intersection is projected to operate at LOS F in the AM peak and LOS E in the PM
peak.
The LOS E/F condition is typical for stop-controlled approaches onto major streets like
Masonboro Loop Road, and the delay is expected to be short-lived. Based on turn lane
warrant analysis, a 100-foot northbound right turn taper turn lane on Masonboro Loop
Road is recommended for build-out in both conditions of amenity uses open and not
open to the public. This turn lane was included in the analysis of both scenarios with
and without the amenity uses open to the public. More information on the turn lane
warrant can be found in the appendix.

04/07/2016 160273 Trinity Landing – Transportation Impact Analysis 26
6.0 Summary and Conclusion
The proposed Trinity Landing development is to be located on Masonboro Loop Road in
New Hanover County, North Carolina. The development is planned to consist of 220
senior adult housing dwelling units, a 7,350 square foot restaurant, a 2,150 square foot
convenience market, a 900 square foot beauty spa, and a 6,900 square foot wellness
center. The development will utilize one (1) access point on Masonboro Loop Road.
If the amenity uses are open to the public, the trip generation indicates that the
proposed development is expected to generate a net total of 1,057 trips per day with 63
trips in the AM peak and 93 trips in the PM peak.
If the amenity uses are NOT open to the public, the trip generation indicates that the
proposed development is expected to generate a net total of 757 trips per day with 42
trips in the AM peak and 51 trips in the PM peak.
DAVENPORT was retained to determine the potential traffic impacts of this
development and to identify transportation improvements that may be required to
accommodate the impacts of both background traffic and new development traffic.
Per the developer’s plan and commitments, a northbound right turn into the site is
desired. Based on turn lane warrant analysis, a 100-foot northbound right turn taper is
recommended for build-out in both conditions of amenity uses open and not open to the
public.
In conclusion, this study has reviewed the impacts of both background traffic and
proposed development traffic, and has provided recommendations to accommodate
future traffic. Please note the proposed site access should be designed according to
NCDOT standards.
