Existing intersections at 121st Street NE and Lilac Street will be <br />converted to roundabouts, while intersections at Robinson Drive, Century Trail, and Palomino Lane <br />will be converted from stop-controlled to right-in/right-out (RIRO) conflguration. <br />Regarding the Sunset Avenue Reconstruction Project and the proposed Northwest Main Street <br />Development, two main concerns have been raised by the community as follows: <br />1. Traffic Impacts from the Northwest Main Street Development <br />The TIA projected that traffic volumes on Robinson Drive and Century Trail could more than <br />double during the 2045 morning and afternoon peak hours due to development-generated <br />site trips. <br />2. Traffic Pattern Changes due to Sunset Avenue Reconstruction <br />The conversion of existing intersections at Robinson Drive, Century Trail, and Palomino <br />Lane to RIRO conflgurations is expected to result in up to 0.8 miles of additional travel <br />distance for some local trips. These trips would need to use nearby roundabouts to <br />complete U-turns before continuing toward their destinations. Community members <br />expressed concerns that this may lead to increased traffic on adjacent local streets as <br />drivers seek alternative routes. <br />This study incorporates information from a Traffic Impact Analysis (TIA) prepared by Kimley-Horn for <br />the proposed Northwest Main Street Development. Figure 1 displays the future roadway network <br />and proposed development area. <br />Page 6 of 228
