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.

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.

This report follows the methodology for MUSP utilized throughout the City of Miami. The traffic impacts to the adjacent roadways were evaluated as well as signalized and unsignafized intersections that were most affected by this 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 RICHARD GARCIA & ASSOCIATES, iNC. e ertiesLLC MUSP tTic Jmpact Study • op 2.0 Project Description / Location The following land use. as idenfified by the Institute of Transportation Engineers (ITE), most closely resembles the proposed development.

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. RICHAR ARC1A} AV;octATEs, C.

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.
