Fernandez, Esq. Bercow & Radell, P.A. 200 South Biscayne Boulevard Suite 850 Miami, Florida 33131 RE: The Roads Edge - Residential Town Home Development SW 9th Court and SW 11th Street Traffic Generation Statement Dear Mr. Fernandez: Per your request, Transport Analysis Professionals, Inc. (TAP) has estimated the trip generation regarding a proposed 26- unit town house development (The Roads Edge) located in the northeast corner of SW 9` Court and SW lithe Street in the City of Miami, Florida. As we understand it, city staff has waived the need for a comprehensive traffic study usually associated with larger MUSP type developments. Using the sixth edition of Trip Generation, published by the Institute of Transportation Engineers (ITE), daily, AM and PM peak hour traffic is estimated as follows: Daily AM Peak Hour PM Peak Hour Land Use Volume In Out Total In Out Total Town House 26-units 207 3 15 18 14 6 20 Miami -Dade County's MUATS planning model was used to estimate the cardinal trip distribution for traffic in TAZ # 1049, which is the zone where the site is located. The distribution of site traffic is estimated as follows: NNE 15.45% ENE 17.53 % ESE 4.38 % SSE 1.65 % SSW 7.20 % WSW 19.39 % WNW 16.32 % NNW 18.02 % The highest concentration of traffic will occur west- southwest (WSW) of the site during the AM peak hour period with about three (3) trips per hour (19.39% * 15 = 2.9). Three (3) trips per hour, which is one vehicle every 20 minutes, will be virtually unnoticeable to the average motorist. Therefore in our opinion, traffic generated by the proposed site will not degrade existing levels of service at nearby intersections or roadways.
