2.0 EXISTING CONDITIONS ANALYSIS
2.1 Roadway Segment Capacity
The study roadway segments were analyzed by comparing the existing directional peak hour
traffic volumes of each roadway segment with its corresponding capacity. Roadway segments
and capacities were obtained from the St. Lucie Transportation Planning Organization (TPO) and
were updated with field traffic movement counts. Excerpts of the St. Lucie Traffic Counts and
Level of Service Report Fall / Winter 2019 / 2020 and the historical AADT’s obtained from FDOT
Florida Traffic Online (FTO) are included in Appendix C.
The analysis, summarized in Table 1, reveals that all study roadway segments currently operate
below their adopted capacities.

2.2 Intersection Analysis
An intersection capacity analysis was conducted using Synchro software and the methods of the
Highway Capacity Manual (HCM), 6th Edition. The existing turning movement counts were
collected during the peak season; therefore, a seasonal adjustment factor was not applied. The
PM intersection volumes are displayed in Figure 2. The raw traffic count sheets and the FDOT
seasonal factor report are included in Appendix D.
The capacity analysis, summarized in Table 2, reveals that all study intersections currently
operate at an adequate LOS. Detailed analysis worksheets are included in Appendix E.

3.1 Trip Generation
The traffic generation of the proposed development was calculated using the Institute of
Transportation Engineers (ITE) Trip Generation Manual,10th Edition.
The trip generation calculation for the project is summarized in Table 3 and detailed ITE trip
generation worksheets are provided in the Appendix F.
Table 3
Trip Generation Analysis
The proposed development is projected to generate a total of 197 trips per day, of which 22 trips
occur during the PM peak hour.
3.2 Trip Distribution
A trip distribution pattern was estimated for the project based on site location, the surrounding
area, and the general traffic flow patterns. The trip distribution is illustrated in Figure 3. Project
trips were assigned to the adjacent roadway segments and intersections based on this distribution
pattern.

4.0 PROJECTED CONDITIONS ANALYSIS
4.1 Roadway Segment Capacity
Projected background traffic growth for the buildout year 2022 was calculated based on the
historical growth trends experienced on Turnpike Feeder Road. The growth rate for the roadway
segment was established based on historical traffic volume (AADT) obtained from FDOT’s Florida
Traffic Online (FTO). A review of historical patterns indicates that the growth rate is less than 2%
within the study area; therefore, background traffic volumes were calculated based on a minimum
2% annual growth rate. The historical volumes and growth trends are included in Appendix G.
Projected roadway conditions were analyzed by comparing the projected traffic volumes on the
study segments to their capacities. The total projected traffic volume is composed of background
traffic and project trips.
Table 4 summarizes the projected conditions roadway capacity analysis for the PM peak hour.
The analysis indicates that the study roadway segments will continue to operate below their
adopted capacities, except for N Kings Highway from St. Lucie Boulevard to Indrio Road which is
projected to operate with a v/c of 1.005 at project buildout due to the background traffic. The
storage facility only adds one trip to this segment.

4.2 Intersection Analysis
An intersection capacity analysis was conducted using Synchro software and the methods of the
HCM, 6th Edition to assess the projected operating conditions at the study intersections.
Background volumes were calculated by applying a minimum 2% growth factor at each
intersection. Additionally, project trips were assigned to the respective movements based on the
project traffic distribution pattern. The projected PM peak hour intersection volumes at project
buildout are illustrated in Figure 4.
The results of the analysis summarized in Table 5 show that the study intersections will continue
to operate at satisfactory LOS at project buildout. Detailed printouts of the HCM capacity analysis
and projected volume worksheets are included in Appendix H.

5.0 SITE ACCESS REVIEW
The site is proposed to be served by two (2) full access driveways; one (1) shared access
driveway at Indrio Crossings Plaza on SR 713 / Turnpike Feeder Road, and one (1) full access
driveway on Miramar Avenue. SR 713 / Turnpike Feeder Road is a 4-lane divided roadway with
a posted speed of 45 mph in the area. Miramar Avenue is a 2-lane undivided roadway with a
posted speed of 25 mph in the area.
5.1 Turn Lane Warrants
A review of warrants for a right and left turn deceleration lane on Miramar Avenue at the access
driveway was conducted to determine if turn lanes are necessary to maintain the integrity of traffic
flow and capacity of the roads during the peak hours. The analysis shows that right and left turn
lanes are not warranted. The access that connects with the Indrio Crossings Plaza has an existing
dedicated northbound right and southbound left turn deceleration lane. The review was
conducted using the methodology of the National Cooperative Highway Research Program
(NCHRP) Report 457. The warrant analysis worksheets are included in Appendix I.

6.0 STUDY CONCLUSIONS
This traffic impact analysis was conducted to assess the impact of the proposed 130,681 square-
foot storage facility in St. Lucie County, Florida, for buildout year 2022. The analysis was
conducted in accordance with St. Lucie County Traffic Impact Analysis requirements. The study
included a determination of project trip generation, a review of existing and projected conditions
for the study roadways and intersections, and a review of the access driveways. The results of
the analysis are summarized as follows:
The proposed development is projected to generate 197 trips per day, of which 22 trips
occur during the PM peak hour.
Analysis of the roadway segments reveals that the study roadway segments will continue to
operate below capacity at project buildout; except for the segment of N Kings Highway from
St. Lucie Boulevard to Indrio Road which is projected to operate with a v/c of 1.005 at project
buildout due to the background traffic. The storage facility only adds one trip to this segment.
Analysis of study intersection capacity reveals that all intersections in the study area
currently operate within their adopted capacity and will continue to do so at project buildout.
The project driveways will operate at an adequate LOS.
Turn lanes are not warranted on Miramar Avenue.
The development is not anticipated to adversely impact the surrounding transportation
network.

Capacity Analysis
The TIS will include an analysis of the peak hour conditions in the existing year and the project
buildout year (2022). The capacity analysis will be based on service volumes from Florida
Department of Transportation’s (FDOT) 2020 Quality/Level of Service (Q/LOS) Handbook and
the methods of the Highway Capacity Manual (HCM), 6th Edition. Roadway conditions and
intersections will be analyzed for the PM peak conditions.
Projected Traffic
Projected background traffic for the buildout year (2022) will be calculated using a 5-year historical
annual growth rate or a minimum annual growth rate of 2.0%.
Traffic Analysis
The traffic study will include existing and 2022 buildout conditions for the roadway segment and
intersection capacity analyses. The buildout traffic includes existing and projected background
traffic. Roadway segments will be analyzed for the PM peak directional volumes. The study
intersections will be analyzed for PM peak hour operations. The capacity analysis will be based
on field counts, buildout traffic, service volumes from FDOT’s 2020 Quality/Level of Service
(Q/LOS) Manual and Synchro software methods of Highway Capacity Manual (HCM), 6th Edition.
Access Review
Project access driveways will be analyzed for turn lane warrants. Offsite and access
improvements necessary to support the proposed development at buildout will be identified in the
study.
Planned and Programmed Improvements
Planned and programmed improvements that may be available from the County’s Capital
Improvement Program (CIP), the FDOT’s Work Program, and/or the Transportation Improvement
Program (TIP) for any of the study segments will be utilized, if applicable.
Report
A report will be prepared for submittal to FDOT and St. Lucie County documenting the analysis
and findings.
