Therefore, traffic <br />forecasts were developed for year 2013 conditions (one year after construction). Based on <br />existing area growth patterns and historical average daily traffic (ADT), volumes, an annual <br />growth rate of one percent was applied to the existing peak hour volumes to develop year 2013 <br />background traffic forecasts. To determine the trip generation for the proposed development, the <br />ITE Trip Generation Handbook, 81h Edition was used. Trip generation estimates for the <br />proposed development are shown in Table 2. <br />T'abl�e 2, <br />T'rii p Generation Estimates <br />Land Use Type (ITE Code) <br />Size <br />(Units) <br />A.M.

The directional distribution is show in Figure 4. <br />Roadd way Connection Impacts <br />As part of the proposed development, new roadway connections will be constructed at <br />County Road C2 to the east and Fernwood Street to the west. These connections will have an <br />impact on existing neighborhood travel patterns. The most impacted travel pattern will be <br />vehicles traveling along Lexington Avenue (south of Josephine Road), that originate or are <br />destined to the Fernwood Street and Merrill Street intersection area. Due to the proposed <br />roadway connection, vehicles currently using Josephine Road to access Fernwood Street from <br />the south will likely use the proposed roadway connection and County Road C2. <br />To determine the extent of the impact of the new roadway connection, observations were <br />completed along Josephine Road to determine the amount of vehicles that may potentially <br />change their travel pattern. Based on the observations completed during the a.m. and p.m. peak <br />hours, approximately 110 vehicles per day (vpd), may change their travel pattern from Josephine <br />Road to the proposed roadway. Although it is unlikely that all 110 vpd will change their travel <br />patterns, in order to provide a conservative analysis all I10 vpd were assumed to change. It <br />should be noted this correlates to approximately 10 vehicles during the a.m. and p.m. peak hours <br />changing their travel patterns. <br />It should also be reiterated that there are five new homes that will have driveways located along <br />County Road C2 as part of the proposed development. These homes are located west of the <br />discontinuous County Road C2 roadway segment and will gain access to and from the west. <br />This will result in approximately five additional trips along this segment of roadway during the <br />a.m. and p.m. peak hour and 48 trips on a daily basis. The combination of background traffic, <br />trips generated by the proposed development and potential travel pattern impacts for year 2013 <br />build conditions are shown in Figure 5. <br />Page 6 of 11 <br />
