Appendix B, continued . Movements counted by OSM in 1996 as part of Centre Pointe EA W and factored up by 2% (based on past historical growth rate) over one year to reflect 1997 conditions: Cleveland Avenue/County Road C2 (South Centre Pointe Drive) Cleveland AvenuelI-35W northbound ramps . Movements counted by Barton-Aschman in ] 994 as part of ] 994 Centre Pointe Traffic Impact Study and factored up by 2% (based on past historical growth rate) over three years to reflect ] 997 conditions: West 1-35W ramps/County Road D East 1-35W ramps/County Road D The existing turning movement volumes at the Fairview Avenue / Terrace Drive intersection were not counted or estimated because the intersection will change following the construction of the proposed Twin Lakes Parkway connection. The existing daily traffic demands on each of the roadways surrounding the Twin Lakes area were obtained from the ] 994 MnlDOT Traffic Flow Maps and 1995 traffic counts conducted by Ramsey County for the four-lane undivided segment of Cleveland Avenue. The data is shown in Figure B3. The data indicates that the four lane undivided segment of Cleveland Avenue, between the I-35W northbound ramps intersection and the County Road D intersection, currently services approximately 7,500 vehicles per day (vpd). The data also indicates that the existing ADT along County Road C near Fairview A venue is roughly] 5,000 vpd. TRAFFIC FORECASTS PM peak hour and average daily traffic (ADT) forecasts were prepared for Design Year 20]], the year following the expected completion of the Twin Lakes Development. The Year 20] 1 forecasts are comprised of forecast Year 20]] background traffic conditions plus projected site-generated traffic. Background traffic conditions refer to the estimated traffic demands that would be present in Year 2011 if the sites within the Twin Lakes Project Area slated for redevelopment were vacant. Site-generated traffic consists of traffic attributable to sites slated for redevelopment within the Twin Lakes Project Area. The following paragraphs describe the methodology used to develop the Design Year 20]] forecasts. Develooment of 2011 Back2round Traffic Forecasts The City of Roseville Traffic Model was used to estimate 2011 background traffic conditions. Previously, Years 1990 and 2010 had been established as the base and forecasts years, respectively, for the Roseville Model. It was decided that the 2010 model would be used and that the ADT results would be factored up by one percent to reflect 201] conditions. This percentage is based on the average annual growth rate between the total trips in the ] 990 and 2010 trip tables. Based on consultation with the City of Roseville, it was decided that the land use and trip generation assumption assumptions previously used to forecast trips in 20] 0 would stay the same except for the following changes given in Table B] and Table B2 below. Table B] identifies recent or expected (re)developments near the Twin Lakes Project Site. Adjustments were made to the land use and corresponding trip generation assumptions in those areas based on this new infonnation. Figure B4 depicts the size and location of the traffic analysis zones (T AZ) referred to by this table. The model uses the traffic analysis zones to detennine the beginning and end points of generated trips. Table B2 #24397 57
