The added traffic of the. new development does <br />not degrade the operations of the intersections below LOS D;. ~xcept at. 167th Avenue NW <br />at TH 47 where level of service drops from·an acceptable LOS D to:LOSE. -The lef~:turn <br />movement from eastbound t 67th Avenue ~ to .Northbound TI-I 47 in.t-he, PM peak hour <br />reaches delays longer than drivers are comfortable with: Votm,ne toeapacit, y ratios are <br />consistently below 1.00 for all movements at all intersections even Mth a'LOS E. <br /> <br />Mitigation Measures <br /> <br />A stop sign will need to be placedat all development:entrances ~ha.t !ntersec~ with the <br />surrounding roadway network. <br /> <br />Geometric changes· and a fully actuated signal: system were. modeledwith Synchr0. asa <br />solution to remedy the low' level of service at the.intersee.tion..of! 67t~ Avenue N~and <br />Tiff 47.
