Sufficiency Letter — W.O. # 114
Dear Ms. Medina:
Via Fax and US Mail
Subsequent to our July 27th 2005 review comments for the subject project, we have received
two response letters on August 3rd and August 5th 2005, prepared by Richard Garcia and
Associates (RGA). Photocopy of both the response letters are attached herewith.
We have also received a revised site plan from the project architect on August 3rd 2005 showing
the maneuverability of the delivery trucks within the project site. The site plan is attached with
this letter. At this time, we conclude that the traffic impact report along with the subsequent
submittals meet all the traffic requirements and the study is found to be sufficient.
Should you have any questions, please call Quazi Masood or me at 954.739.1881.

Executive Summary
The subject project is located at 4350 NW 109' Street in the City of
Miami, Florida. The subject development is a Low -Rise Residential Condo
/ Townhouse with 158 dwelling units. The existing use is an Apartment
Building but will not be analyzed nor have the existing trips been
reduced from the future proposed development.
The Trip Generation calculations of this project reveal there will be
85 net vehicles per hour (vph) in the PM peak hour. The subject
project is located in TAZ 774 and has had the traffic assigned to
the surrounding roadway and transit system using the MUATS
Cardinal distribution.
Link and intersection traffic counts were collected, averaged and
adjusted for seasonal variations and used in the link analysis and
intersection analysis. This analysis was performed for the existing
condition, background, committed and background and with
the cumulative effects of the above and the project traffic. The
results indicated the corridor person trip analysis will not fall below
LOS D for all scenarios.

development. This analysis was performed for the existing and proposed
conditions during the PM Peak Hour.
This report follows the methodologies adopted by the City of Miami's
Person -Trip Analysis and conforms to the Institute of Transportation
Engineer's (ITE) Trip Generation, and Traffic Impact Studies Manual. Lastly,
this report has evaluated the following:
• Trip Generation
• Traffic Distribution
• Traffic Assignment
• Traffic Counts: ATR & TMC
• Existing Level of Service
• Proposed Level of Service
• Existing Intersection LOS
• Proposed Intersection LOS
• Recommendations

3.0 Trip Generation
The trip generation characteristic for the subject project was obtained
from ITE's Trip Generation Manual, 7Th Ed. ITE's Land Use 231: Low -Rise
Residential Condominium was used to determine the trip generation rates
for the proposed development.
The Trip Generation calculations results of the proposed improvements are
summarized below. The ITE rates and percentages for PM Peak Hour Trips
are included in Corresponding tab. Table 1 below summarizes the
greatest traffic impact associated with the subject development, which
occurs during the PM peak. No existing traffic was assumed for the
existing apartments. Therefore, this report did not deduct the existing
traffic from the future trip generation results.
Lastly, the trip generation was converted to net vehicle trip by utilizing the
City's Person Trip Methodology. This methodology uses a 16 % vehicle
occupancy and an 14.9 % transit reduction factors. Lastly, no pedestrian
and bicycle trip reduction was used (0 %). These factors are consistent
with the values used in the City's DRI - Increment 11 for the Omni Area.

6.0 Traffic Counts
For the purposes of the corridor analysis, continuous 72-hour
Automatic Traffic Recorder (ATR) were collected on Tuesday,
Wednesday and Thursday June 28 fhru June 30, 2005. These counts
were averaged, adjusted for seasonal variations and corrected for
multi -axle traffic by utilizing the Florida Department of Transportation
Seasonal Factor (SF) and Axle Correction Factors (ACF) of 1.02 and
0.94, respectively. Table 4 depicts the results of the seasonally
adjusted existing PM Peak hour traffic volume. Lastly, these
calculations were similarly performed for the Average Annual Daily
Traffic (AADT) and are included in the tab labeled TMC's/ATR in the

Corridor Level of Service Analysis
A corridor analysis was performed that follows the City of
Miami's Person Trip Methodology. This methodology has
been utilized in the City's Development of Regional Impact
(DR!) - Increment ii and has been accepted by both the
FDOT and the South Florida Regional Planning Council. Lastly,
this methodology is further detailed in the City's document:
Transportation Corridors: Meeting the Challenge of Growth
Management in Miami.
The results of the corridor analysis reveal that all levels of
service thresholds remain at LOS E for the segment analysis.
Table 7 is a summary of the results while the Person Trip tab
contains the spreadsheet utilized to compute the seasonally
adjusted existing condition, the future year (i.e. 2008)
background condition, the background and committed
condition and finally, the proposed condition containing the
cumulative effects. Although the southbound LeJeune Rd
(NW 42 Avenue) link has an LOS F, this is mainly attributable to
the background growth and not the site traffic. Moreover,
the segment LOS of E is met.

12.0 Intersection Level of Service Analysis
Intersection analyses were performed for the seasonally adjusted
existing condition and the proposed condition at the stop
controlled and signalized intersections using the Synchro/SimTraffic
software. The results indicate the LOS are within acceptable
guidelines for these types of facilities. Table 8 provides a summary
of the results while the Corresponding tab provides the program
output. Future driveway turning movement counts were taken from
the Intersection Approach Volumes worksheet included in the
Corresponding tab.
The capacity analysis was done for the Existing (without site traffic)
and proposed conditions (with site traffic and committed projects)
for the PM peak hour for the intersections as follows:
• NW 10th Street & NW 43rd Avenue (Stop Controlled)
• NW 10th Street & NW 43rd Court (Stop Controlled)
• NW l lth Street & NW 43rd Avenue (Stop Controlled)
• NW 1 lth Street & NW 43rd Court (Stop Controlled)
• NW 7th Street & NW 44th Avenue (Signalized)
