Ramsey Town Center Traffic Analysis FUTURE CONDITIONS ANALYSES Two sets of future conditions, Future Base and Future with Project, were analyzed. The Future Base represents growth in traffic from non -project sources at the year of project buildout, which was assumed to be the year 2007. Regional Growth and Approved Projects A growth factor was used to account for the regional growth in traffic in the area irrespective of the proposed development. This growth factor was calculated to be two percent per year on the basis of forecasts for 2025 from the Metropolitan Council. This level of growth is consistent with the volume projections in the TH 10 IRC Study.' The Future Base also includes the effects of other approved development projects in the vicinity of the project site that anticipate being constructed and occupied within the 2007 time line. The following two projects were identified as having a qualifying development time line: • The Rivenwick 3rd Subdivision residential development, which is located south of TH 10 at Ramsey Boulevard, would have 112 townhouses and would add a fourth leg to the intersection of Ramsey Boulevard and TH 10. • The Bright Keys residential development, located across Industry Boulevard from the project site near Ramsey Boulevard, would have 284 townhouse units. Traffic for the Rivenwick 3rd Subdivision, as reported in that project's traffic study', was added into the Future Base. Traffic for the Bright Keys development was generated using standard trip generation rates and assigned to the study area street system using the data developed for the project traffic forecasts (see below). Figures 4 and 5 show the AM and PM peak hour turning movements for the Future Base conditions. Project Traffic Forecast The proposed development has varied land uses that include residential, retail, civic, recreational, institutional, and office uses. The traffic forecasting process involves estimating the new trips generated by the development and assigning these trips to various study intersections depending on the directional distribution of the trips. Trin Generation Trip generation for the proposed development was estimated using the rates from the 6th edition of the Institute of Transportation Engineers' (ITE) Trip Generation Manual. This is considered a standard reference. Table 1 shows the trip generation for the proposed redevelopment scenario estimated using the ITE rates for both the AM and PM peak hours.
