SUMMARY
The analysis in this report concludes that the Jonathan's Grove
development does not represent an adverse traffic impact, as evidenced by
the following conclusions:
· The future roadway network will be adequate to
provide acceptable levels of service on those links
which are in the project's radius of development
influence.
· The Jonathan's Grove development can demonstrate
compliance with Test 1 of the Palm Beach County
Traffic Performance Standard.
· The proposed development is also in compliance with
Test 2 of the Traffic Performance Standard. This test
analyzes traffic impacts from all approved projects
with respect to the Palm Beach County 2010 Interim
Transportation System Plan.
This report follows the guidelines set forth by the Palm Beach County
Traffic Performance Standard and the Traffic Circulation Element of the
Palm Beach County Comprehensive Plan.

DEVELOPMENT PLAN
Site Data
The proposed development plan will consist of thirty-three (33) single
family homes. Site access will be provided from a single access onto
Lawrence Road.
Scheduled Buildout
The anticipated build out for the project is expected to occur in one phase
by the end of 1994. This report assumes that total traffic impacts will occur
at the time of buildout.

EXISTING ROADWAY CONDITIONS
The foundation for the analysis of traffic impacts from Jonathan's Grove
is the existing condition on the roadway network.
Capacity Analysis
Generalized Daily and Peak Hour Two-Way Service Volumes and
Capacities are found in the Palm Beach County Traffic Performance
Standard. They include the Level of Service "D" thresholds shown in Table
1.

Existing Traffic Volumes
Table 2 presents data from traffic count stations in the area. Counts were
taken from the most current Palm Beach County Metropolitan Planning
Organization (MPO) Traffic Volume Count Map (1992 ADn. Peak hour
volumes were generated by using a "K" factor of 0.096 which is consistent
with the Palm Beach County Traffic Performance Standard.
The traffic volume for Hypoluxo Road east of Lawrence Road was reduced
to 95 percent of the Palm Beach County AADT 1992 volume for the link.
This reduction was made because the County count location is 225 feet
west of Congress Avenue, which is east of two driveways for the Meadows
Square Shopping Center. Therefore, the County traffic count includes trips
to and from the shopping that do not travel along the west end of the link
to Lawrence Road. The volume used for Hypoluxo Road, east of
Lawrence Road, was 95 percent of 26,834, or 25,492 vehicles.
For the link of Hyppoluxo Road west of Lawrence Road, an AADT 1992
volume was unavailable, since Palm Beach County conducted only an off-
peak season count in 1992. Therefore, the 1992 volume used to reflect
exising conditions on this link was based on the AADT 1991.
The v / c ratios shown in Table 2 are simply the volume divided by the
capacity. If the ratio is one (1.00) or less, then the volume on the roadway
is at or better than the Level of Service "D" threshold which is acceptable
as defined by Palm Beach County standards.

FUTURE CONDITIONS
Before evaluating the relative traffic impacts from Jonathan's Grove, the
future conditions on the roadways without the project impacts were
established. These conditions are described by the future traffic volumes
expected at the time of build out in 1994 and the assured roadway network.
Roadway Improvements
An examination of both the Palm Beach County and FDOT Five Year
Work Program indicates that there are no roadway improvement projects
in the area scheduled for construction in the last quarter of Fiscal Year
92/93.
The new interchange with 1-95 at Northwest 22nd Avenue (Gateway
Boulevard) has been recently constructed and is now open to traffic. The
addition of this interchange is expected to provide a reduction in traffic
volumes along major east/west roadways in the area, such as Boynton
Beach Boulevard and Hypoluxo Road.

Future Traffic Volumes
In order to assess the availability of capacity at the buildout of Jonathan's
Grove future traffic volumes were formulated. A review of historical traffic
volumes in this area shows varied growth rates on the roadway segments
as can be seen in Table 3.

With the opening of the Gateway Boulevard/Interstate 95 interchange,
future growth along Hypoluxo Road east of Lawrence Road is not expected
to be as high as the 8.65 percent historical trend. A growth rate of 5
percent per year is more realistic. Therefore, the following per annum
rates will be used to reflect future conditions at the buildout of Jonathan's
Grove in 1994.

Major Developments
Another component in the development of background growth data is
approved committed development in the area. According to Palm Beach
County data, three major projects are located within the area of Jonathan's
Grove:
· Boynton Beach Park of Commerce DRI
· Motorola DRI
· Melear PUD
As indicated by the Traffic Performance Standard..."only the traffic
generated from the unbuilt portions of the major projects as set forth above
which are projected to be built during the buildout period of the proposed
project shall be considered." In addition, major projects..."which will add
more than ten percentum of the LOS D volume to any link within the
proposed project's radius of development influence during the buildout
period of proposed project shall be specifically accounted for in projecting
traffic."
The Boynton Beach Park of Commerce, also known as Quantum Park, is
a multi-use development on approximately 540 acres located on both sides
of Northwest 22nd Avenue between Congress Avenue and Interstate 95.
441SIUI-ROS93
-11-
LTK-Ol
I Kim/ey.Horn I
The project is expected to generate a total of 31,403 external trips at its
buildout in 2013. Development equivalent to 12,018 trips has been
constructed leaving proposed development yet to be constructed equal to
19,385 daily trips within the next ten years. It was estimated that
approximately 20 percent or 3,877 trips are expected to come on line
concurrently with the Jonathan's Grove by 1994. It is not expected that
the projected traffic assignment from Boynton Beach Park of Commerce
will exceed ten percent of capacity on any of the roadway segments located
with the Jonathan's Grove study area.
The Motorola development is located at the southeast quadrant of
Northwest 22nd Avenue and Congress Avenue in the City of Boynton
Beach. It is proposed for 825,000 square feet of industrial area of which
approximately 53 percent or 436,000 square feet has been developed. The
remaining 2,700 trips yet to be developed are not expected to exceed ten
percent of Level of Service "D" capacity on any of the roadway segments
located within the Jonathan's Grove study area.
The Melear PUD is located on Congress Avenue between Hypoluxo Road
and Northwest 22nd Avenue. Of the 1,005 residential units and 30,000
square feet of retail, 332 units have been built. Of the remaining trips,
most are expected to head east toward Interstate 95 and south to
Northwest 22nd Avenue, and should not exceed ten percent of the Level
of Service "D" capacity on any of the roadway segments in the study area.

TRAFFIC GENERATION
Traffic generation is the method by which the amount of traffic, or the
number of trips to and from a proposed site is estimated. Two
authoritative sources were used to estimate traffic generation. Daily traffic
generation was based on Article 10 of the Palm Beach County Unified
Land Development Code. Peak hour traffic generation was based on the
Institute of Transportation Engineers (ITE) report, Trip Generation, (Fifth
Edition).
Table 5 summarizes the trip generation for the Jonathan's Grove
development on a daily and peak hour basis. It is clear from Table 5 that
the PM peak hour activity of the proposed site would have the greatest
impact to the adjacent roadway network when examining peak hour
impacts. Therefore, the PM peak hour was the only peak hour analyzed.

TRAFFIC ASSIGNMENT
Traffic assignment is the procedure by which traffic generated from a
proposed development is allocated to the roadway system. An examination
of land uses in the surrounding area forms the basis for assigning traffic
from the Jonathan's Grove site to the roadway network.
Figure 2 presents the results of the traffic assignment in percentages, along
with the daily and PM project traffic.
Project related traffic at the access point along Lawrence Road for the AM
and PM peak hours can be found on Figure 3.

TRAFFIC PERFORMANCE STANDARD
Section 7.9 of the Palm Beach County Unified Land Development Code,
the Traffic Performance Standard, sets forth the criteria by which the
potential traffic impacts associated with proposed development in Palm
Beach County are evaluated.
Provisions of the Standard
The Traffic Performance Standard consists of two tests, both of which must
be satisfied in order for a site specific development order to be issued:
· Test 1 - Evaluation of the roadway network on a daily
and peak hour basis at the buildout of Jonathan's
Grove, and
· Test 2 - The Year 2010 network evaluation
incorporating traffic impacts from all approved
projects.
If both of the tests can be satisfied, the project can be given development
approval.

, Kim/ey-Horn 1
Radius of Development Influence
According to the Palm Beach County Traffic Performance Standard, since
Jonathan's Grove generates 330 daily trips a maximum radius of
development influence (RDI) of one-half mile was established.
Impact on Roadway Links
The impact of the project related traffic from Jonathan's Grove is
calculated in terms of the amount of the existing daily Level of Service "D"
Service Volume consumed. Accordingly, the traffic impact is shown in
Table 6.
The column in Table 6 headed Percent Level of Service "D" is an
indication of the percentage that the project traffic assignment consumes
of the daily Level of Service "0" Service Volume, which is the criteria
established by the Palm Beach County Ordinance.

CAPACITY ANALYSIS
The requirements for capacity analyses focus on an examination of
conditions on all roadway links within the RDI.
Link Capacity Analysis
The existing and future conditions on the roadway network in the area of
Jonathan's Grove have been presented in earlier sections of this report.
Table 7 presents future average daily and peak hour traffic conditions in
1994 on all RDI links. The volumes in these tables include the background
growth component and the traffic expected from the Jonathan's Grove site.
Compliance with the Standard - Test 1
The primary policy determination in the Palm Beach County Traffic
Performance Ordinance, is that all links within the RDI must operate
within the Level of Service "D" standard at buildout of the proposed
project. The links on Table 7 are expected to operate within this standard
and therefore, are in compliance with the daily and peak hour analysis in
Test 1 of the Traffic Performance Standard.

Compliance with the Standard - Test 2
Test 2 of the Traffic Performance Standard involves an examination of the
County Transportation Model addressing approved development projects
and the 2010 network. The data in Appendix A indicate those roadways
which are expected to experience unacceptable operating conditions in the
Test 2 Model. None of the roadways within the Jonathan's Grove RDI are
expected to operate at unacceptable levels of service according to the 2010
Test 2 Model. Therefore, the project is in compliance with Test 2 of the
Standard.

CONCLUSION
The foregoing analysis has addressed the relative impacts associated with
the Jonathan's Grove project. It can be concluded that the Jonathan's

Jonathans Grove
Boynton Beach, Florida
This project is located in Section 7, Township 45, Range 43, and within the municipal
boundary of the City of Boynton Beach, Florida.
The project site is 10.0 acres in area and will consist of thirty-two single family home sites
with average lot size of 9,600 square feet. Primary drainage will be provided through 15'
swales and 20' swales along the front and back of the lots, respectively. All swales flow
westerly and discharge to a 330 feet by 60 feet dry retention area which will be furnished
with a water control structure with an outlet pipe directed to the drainage ditch that runs
along the full length of the western property line.
The dry retention pond and four (4) dry swales will provide the water quality treatment
required.

The total storage volume provided in the dry retention pond and two dry swales is
approximately 1.92 Acres-Feet, which is much greater than the required volume of 1 .04
Acres-Feet. Therefore, the storage area provided satisfies the requirement.
According to the soil report, a layer of hardpan was found between depths of 2.2 and 5.3
feet below the existing ground surface. If hardpan is found in the dry retention area, it
should be removed and replaced with clean sand. The results of the double ring
infiltrometer test indicate a permeability of about 6 inches per hour which reflects the
permeability of the upper clean sand found in the project site. Therefore, the recovery
time of the dry retention pond will be approximately 6.0 hours.
According to FEMA Flood Insurance Map (Panel No. 01908), the project site is located
in Zone 8 which is outside of the 1 OO-year flood plain area.

RE:
TRAFFIC OBSERVATIONS - LAWRENCE ROAD
The 1994 average traffic count on Lawrence Road between NW 22nd
Avenue (Gateway) and Hypoluxo has been reported to us by the County
to be 7972 trips. The current FDOT Level of Service Manual defines
the threshold traffic level for LOS D for 2 lane undivided streets
as 13,400 trips.
Those two numbers are important in studying Lawrence Road traffic
because the Palm Beach County Traffic Engineering Division has
informed Mr. Hall of this office that widening of two lane roads in
the County system is not seriously considered until LOS D is
reached. Lawrence Road is a County road.
The Traffic Division has also opined that about 1000 more units can
be occupied on Lawrence Road before LOS D is reached. well over
1000 more units have been approved by either the City or County, as
follows:
L Lawrence Oaks 178 units
<-- Nautica I 177 units
t... Nautica II 197 units
j.. -Meadowwuod GLOV~ ( cl ktt Knollwoodlb,.,os 539 units
Fox Hollow (aka Manor Forest) 185 unbuilt units, est.
L..- Sausalito Groves 164 unbuilt units, est.
i.--- Jonathan's Grove 32 units
..... Lawrence Grove 75 unbuilt units, est.
/.- Citrus Glen 20 unbuilt units, est.
j...-- Citrus Park 113 units
TOTAL
1680 unoccupied units
The figure 1680 is not propounded to be exact, because each of the
entries marked "unbuilt units" represents our estimate of how many
units remain to be occupied in uncompleted developments. Traffic
from occupied units appears in actual traffic counts totaling 7972
trips. We believe it is reasonable to predict that when all
unoccupied units in all listed developments are in place, the Level
of Service Standard will exceed LOS Standard E, which is 15,000
trips. LOS D will be reached when approximately 2/3 of the 1680
future units are occupied.
Engineering Division Memo No. 95-059
Traffic Observations - Lawrence Road
March 6, 1995
Page #2
We have been unable to obtain accurate estimates of revenue
collected from dwelling units now contributing to the 7972 trips on
Lawrence Road. If we assume 1600 dwelling units have generated
those trips, and the average traffic impact fee collected was $1500
per unit, the total fees generated to date exceed $2,400,000. The
total fees due from 1680 additional units will exceed $2,500,000,
representing a total at build-out of $5,000rOOOI generated by these
developments to be spent in the immediate area. These numbers are
estimates, of course, and should be adjusted for traffic impact
fees generated by other users who pay such fees (commercial, etc.)
and those who don't (schools).
Our conclusion is that it is time for the County to begin planning
for widening of Lawrence Road so that when LOS D is reached, action
can be immediately implemented to begin construction. A four lane
undivided road will support 23,520 trips at LOS D, which is
adequate for all completed and currently proposed development along
Lawrence Road.
