INTRODUCTION
A Wal*Mart Supercenter is proposed to be located west of Winchester Park
Boulevard between Boynton Beach Boulevard and, Old Boynton Road in Boynton
Beach, Florida. The proposed site plan consists of 220,000 square feet of general
commercial retail.
Kimley-Hom and Associates, Inc. was retained to prepare a traffic impact analysis
for the project. This document presents the methodology used and the findings of
these analyses.
The traffic impact analysis was conducted in accordance with the Traffic
Performance Standards of Palm Beach County. The analysis used current data
available from Palm Beach County. The buildout year for the proposed
development is 2000.

INVENTORY AND PLANNING DA TA
Inventory
The data used in this analysis were obtained from Palm Beach County. They
included:
. 1998 24-hour traffic volumes
. 1997 and 1998 intersection turning movement counts
. Roadway geometrics
. Approved development traffic
. Historic count data
The location of the site is shown in Figure I.
Planning Data
Access to the development will be provided through two full access driveways on
Winchester Park Boulevard and one full access driveway on Old Boynton Road.
The two driveways on Winchester Park Boulevard are located at existing median
openings.

PROJECT TRAFFIC
Traffic Generation
The daily traffic generation for the development was based on trip generation rates
published by Palm Beach County. Peak hour characteristics were based on
information published in the Institute of Transportation Engineers' Trip Generation
Report (6th Edition). Table I presents the proposed potential trip generation for the
project site. Pass-by rates published by Palm Beach County were used in the
analysis. Internalization was assumed to be zero.
Traffic Distribution
From a review of the existing and approved development in Palm Beach County
and considering the arterial network with its travel time characteristics, the external
traffic distribution was calculated. These were summarized by general directions
and are depicted below:
NORTH
SOUTH
EAST
WEST
30%
30%
15%
25%

Traffic Assignment
The distributed external trips for the project in 2000 were assigned to the roadways
within the radius of influence, both in terms of daily external trips and A.M. and
P,M. peak hour volumes.
Based on the net impact of the project, it was determined that the maximum radius
of development influence for Test I of the traffic performance standards is three (3)
miles. The maximum radius of development influence for Test 2 is two (2) miles.

BACKGROUND TRAFFIC
Background traffic is comprised of two components:
. Traffic from the unbuilt portions of approved major developments
· Historical growth
Major projects found in the Palm Beach County spreadsheet <<Approved
Development Traffic in West BoyntonlDelray Area" were included in the analysis.
Trips from projects with a buildout later than 2000 were calculated through linear
interpolation. No other major projects would contribute greater than ten percent
(10%) of the level of service standard on any link significantly impacted by the
project during its buildout time frame.
According to the requirements of the Traffic Performance Standards of Palm Beach
County, existing traffic volumes were grown by factors determined by a review of
growth data published by Palm Beach County.
The total background traffic was determined for each link within the radius of
influence by applying the growth rate through the buildout year and adding major
project traffic.

ASSURED CONSTRUCTION
The existing laneage for each link analyzed was identified. A review of the Five-
Year Plans of Palm Beach County and FOOT, as well as those improvements
committed by the developers of projects in the area: was made to identify pertinent
roadway improvements. The following roadway improvement is planned:
. Lawrence Road from Boynton Beach Boulevard to Gateway Boulevard
Widen to five lanes (construction to commence in FY 2000/200 I)
· Lawrence Road from Gateway Boulevard to Hypoluxo Road
Widen to five lanes (construction to commence in FY 1998/1999)
. Congress Avenue from Miner Road to Hypoluxo Road
Widen to six lanes divided (construction to commence in FY
1997/1998)

LINK EVALUA TION
Test 1
A link performance standard evaluation was undertaken for each link considering
its total traffic volume and the roadway laneage to be in place in 2000. Project
traffic and total traffic for 2000 are shown in Tables 2 and 3 for daily and average
peak hour conditions. Figure 2 depicts the roadway links that are significantly
impacted on a daily basis by project traffic. As can be seen, two of the roadway
links upon which the project has significant impact fail to meet the daily level of
service standard through 2000. Table 3 shows that the same two links fail to meet
the average peak hour link standard for 2000.
Alternate Test 1
The two links that failed to meet the daily and average peak hour standards were
then analyzed for peak hour peak season conditions in order to determine if they
would meet the Alternate Test I. Table 4 shows the peak hour directional link
volumes for these links. As can be seen from Table 4, Boynton Beach Boulevard
from Jog Road to El Clair Ranch Road fails the peak hour link level of service
standard.
For the project to meet Palm Beach County's Traffic Performance Standards,
Boynton Beach Boulevard from Jog Road to El Clair Ranch Road will have to be
widened to six lanes divided. With this improvement in place, the project will meet
the daily level of service standard through 2000.

In addition to the link level of service analysis, intersection critical volume analyses
were also conducted for the intersections on Old Boynton Road and are included in
the Appendix. Existing intersection volume data was provided by Palm Beach
County at the two major intersections. The counts were adjusted to peak season (if
necessary) and grown to the 2000 buildout year using the weighted average growth
rate of the intersection approaches. The worksheets in the Appendix show the
development of total 2000 intersection traffic. The two major intersections were
then analyzed for adequate capacity during the A.M. and P.M. peak hours.
The critical volume analysis worksheets show that one intersection operates over
the standard capacity of 1,400 vehicles. The intersection of Old Boynton Road and
Congress A venue exceeds the standard capacity by 10 vehicles during the PM peak
hour. The intersection was reanalyzed with a westbound right-turn lane. With this
improvement in place, the intersection critical volume will drop below the 1,400
vehicle capacity.
The links that fail the daily link test therefore meet Alternate Test I, with a
westbound right-turn lane at the intersection of Old Boynton Road and Congress
Avenue. Boynton Beach Boulevard from Jog Road to El Clair Ranch Road will
meet Test I with the approved proposed expansion to six lanes divided.
Test 2
The Model Test 2 indicates a radius of influence of two miles from the site. No
roadway segments on the Test 2 failure list lie within the project's two miles of
development influence.

DRIVEWA Y CLASSIFICA TION AND
TURN LANE REQUIREMENTS
Driveway Classification
According to the Palm Beach County "Guide Parking Lot and Street Access Design
Criteria and Standards", it is necessary to classifY project entrances as minor,
intermediate, or major according to the following criteria:
1. Minor - Provides for a maximum average daily traffic of 500.
2. Intermediate - Provides service for a maximum average daily traffic
from 501 to 2,000.
3. Major - Provides service for a maximum average daily traffic greater
than 2000.
Using these criteria, the driveway on Old Boynton Road and the north driveway on
Winchester Park Boulevard would be classified as major. The south driveway on
Winchester Park Boulevard would be classified as minor.
Turn Lane Requirements
Figure 3 presents the proposed project AM and PM peak hour total volumes
assigned to the project's access driveways. Consideration of these volumes with
respect to the Palm Beach County access design standards results in the
determination that a right-turn ingress lane will be required at the driveway on Old
Boynton Road. Left-turn ingress lanes will be required at the north driveway on
Winchester Park Boulevard and the driveway on Old Boynton Road. Both locations
have existing left-turn lanes.

CONCLUSION
This traffic impact analysis shows that the proposed Wal*Mart Supercenter
development meets Palm Beach County's Traffic Performance Standards with the
phasing of the development program to the commencement of the right-turn lane
construction at Old Boynton Road and Congress Avenue and the six-lane
construction of Boynton Beach Boulevard from Jog Road to El Clair Ranch Road.
The development activity of the project should be limited to no more than 5,922 net
new daily trips (or approximately 176,000 square feet of building area) prior to
commencement of the right-turn lane construction. Worksheets are included in the
Appendix which show that the project meets Alternate Test I standards without the
intersection improvement at up to 176,000 square feet. Development activity
should be limited to no more than 5,183 net new daily trips (or approximately
144,900 square feet of building area) prior to commencement of the Boynton Beach
Boulevard construction from Jog Road to El Clair Ranch Road.
No phasing of development activity is necessary for the committed improvements
on Lawrence Road from Boynton Beach Boulevard to Gateway Boulevard and
Congress Avenue from Miner Road to Hypoluxo Road as these links would meet
Test I standards without the improvements. However, development activity should
be limited to no more than 3,575 daily trips (or approximately 83,000 square feet
of building area) prior to commencement of the Lawrence Road construction from
Gateway Boulevard to Hypoluxo Road.
