City of Tukwila Jim Haggerton, Mayor INFORMATIONAL MEMORANDUM TO: Mayor Haggerton Transportation Committee FROM: Bob Giberson, Public Works Director °'0 BY: Grant Griffin, Senior Program Manager DATE: September 5, 2014 SUBJECT: Boeing Access Rd over BNRR Bridge Rehabilitation Project No. 99410408 Informational Draft Alternative Study — 30% Plans Update ISSUE The design of the Boeing Access Rd over BNRR Bridge Rehabilitation Project is approaching the one -year mark. A draft alternative study has been delivered, followed by 30% plans; therefore, an informational update to the Transportation Committee is in order. BACKGROUND In November 2012, the City received Federal Local Bridge Program funding for the Boeing Access Rd over BNRR Bridge Rehabilitation Project. The grant funds were awarded and the Jacobs Engineering Group, Inc. was selected to provide engineering design services through a Request for Qualifications (RFQ) process. Jacobs was sent the Notice to Proceed on October 14, 2013. DISCUSSION Jacobs has performed an in -depth inspection, geotechnical conditions beneath the bridge have been investigated, and the results of this work have been incorporated into an analysis of the existing structure. This analysis has been used to determine options for removing the existing deficiencies thus adding to the bridge's service life as well as it serviceability to the traveling public. In particular, pedestrian and bicycle access and safety will be improved, seismic vulnerability will be reduced, the bridge will be strengthened and existing deterioration and damage will be repaired. FINANCIAL IMPACT There is no financial impact; informational only. Estimate Budget Construction estimate at 30% Plans $9,093,500.00 $ 9,700,000.00 RECOMMENDATION For information only.

BACKGROUND After multiple citizens requested action at the South 148th Street and 46th Avenue South intersection, we recently concluded our traffic engineering investigation and our findings include: 1. There were no recorded traffic accidents from 2006 to 2012 2. There were two recorded accidents in 2012 to 2013 — both accidents involved hitting parked cars 3. There are indications of speeding vehicles 4. Traffic engineering standards dictate that stop signs are not to be installed to control speeding 5. There is 1 existing stop sign on the south leg of the subject intersection that serves northbound 46th Ave S 6. The southwest and northeast intersection corners have obstructed sight distance due to encroaching fences and vegetation 7. South 148th St acts as the major road and 46th Ave S acts as the minor road as far as vehicular volumes 8. Traffic engineering standards dictate that stop signs should not be placed on the major road that intersects a minor road 9. There is significant pedestrian traffic through this intersection to and from local schools ANALYSIS Based on adopted traffic engineering standards and principles, the City proposes to: • Install an additional stop sign on 46th Avenue South, protected by reflectorized guideposts • Work with adjacent property owners to improve sight distance on intersection corners • Install pedestrian warning signs in all directions • Send notices to all affected property owners informing them of the new proposed traffic revisions We understand that stop signs have been requested for all 4 corners, however, it is not supported by engineering standards and principles. Installing stop signs on the major road (South 148th Street), will likely lead to more enforcement and liability issues. Unwarranted stop signs tend to be ignored, which may lead to further accidents and enforcement problems. Our goal is to implement the bulleted traffic revisions listed above as soon as possible.
