Conclusions and Recomnendations The implementation of the Triad Development Holly Drive - Olivia Road apartment projer_t will increase traffic demand3 on the adjacent arterial and collector road system by about 2,270 vehicular trips per day and the evening peak hour traffic volumes, usually the hea.viest peak traffic hour of the day, by about 207 vehicles per hour. The existing road system serving the preject site, including Olivia Road and 9th Avenue W„ are operating at very high levels of service and have substantial surplus capacity. As a consequence, there are no off site mitigating msasures required on any of these facilities. Site access via driveways to both Oiivia Road - 9th Avenue W. , the main driveway, and to Holly Drive, the secondary driveway, can be implemented with appropriate design considerations. The main drivewap should include two outbound lanes so that left and right turning traffic are kept separate. This can be an important consideration when th� east ieq of 100th Street S.W. at Evergreen Way is extended and then offers a bypass to the signal at Everett Mall Way. With high levels 'of servir,e at both driveways at 1e�st up to and probably past 1990, tliere appears to be no need for left turn channeliza�ion on either Holly Drive or 9th Avenue W. - Olivia Road. However, future development in the area may make these an eventuality ard, accordingly, future participation in such construction via an RID would be an appropriate covenant. No other recommendations appear necessary. While the project adds significa:.it traf£ic to the system, the substantial reserve capacity is well able to accommodate the new traffic demands. -11- ,�\ (�1[1&�1Cf B[Y7W� �G ,��J� �$$ IflII11Cf.HV�IIUC fl � �� ,�i � �,��, td 7�345GT 118 ' ��._
