<br />Traffic volumes on the local roadway system will be affected by "background growth" in traffic <br />due to other development in the vicinity of the study area. The regional forecast model and the <br />Centre Point Business Park EA W were used to estimate background traffic growth on each <br />roadway. The year 2020 was assumed as the year of site build-out, corresponding to the forecast <br />horizon year of the City of Roseville Comprehensive Plan. Background traffic is forecast to <br />grow at an annual rate of 0.5 percent to 1.0 percent, depending on the roadway. This would be <br />consistent with an area that is fully developed (excluding the redevelopment site). <br /> <br />In addition to estimating trip generation for the future land uses, the estimated traffic generated <br />by the current land uses was determined so that the net traffic generated by the alternatives could <br />be determined. Table 7 shows the estimated current traffic generation. The area currently <br />generates 1,300 p.m. peak hour trips therefore the proposed redevelopment generates 5.5 times <br />as much peak hour traffic as currently exists. The p.m. peak hour is critical since it represents <br />the highest level of traffic for impacts assessment. The maximum increase is 6.4 times the <br />amount of traffic currently generated. The highest generating alternative includes more retail <br />development, which has a higher ratio of offpeak-to-peak traffic. <br /> <br />Table 7 <br />Traffic Generation of Existing Land Use <br /> ITE Trius Generated <br /> Rate <br />Block Land Use Acres Code Daily PM In PM Out <br />1 truck terminal 14.59 030 1,195 38 57 <br />2 truck terminal 21.03 030 1,722 55 82 <br />3 truck terminal 8.28 030 678 22 32 <br />4 industrial multi-tenant 14.36 030/130 1,034 31 72 <br /> buildings/truck terminal <br />5 industrial building 5.85 130 371 12 49 <br />6 truck terminal and auto repair 8.16 030 668 21 32 <br />7 truck terminal and auto repair 20.79 030 1,703 54 81 <br />8 industrial buildings 7.81 130 496 16 65 <br />9 multi-tenant industrial 21.94 130 1,393 45 183 <br /> buildings <br />10 industrial and manufacturing 12.19 130 774 26 101 <br />11 single family residential/vacant 14.08 210 100 3 3 <br /> land <br />12 multi-tenant industrial 21.19 130 1.346 44 176 <br />Total 170.27 11,480 367 933 <br /> <br />Twin Lakes AVA/? <br />Traffic, Air and Noise Analysis <br /> <br />-13- <br /> <br />SRF Consulting Group, Inc. <br />May 3, 200l <br />
