Zillah - 2nd Avenue and 5th Street Improvements

Speed concerns, unsafe pedestrian conditions, deteriorated pavement, and lack of access control, together presented an opportunity to improve this arterial.  These issues and more were corrected by implementing effective strategies during the design phase, including curb bulbouts to shorten pedestrian crosswalks and serve as traffic calming devices, grinding the existing asphalt and recycling it as the new roadway base, and limiting driveway widths with full height curbs to control access points.  Other project improvements included installation of on-street diagonal and parallel parking, an isolated bus loading zone adjacent to Zillah Intermediate School, a storm drain system, illumination, and concrete sidewalks along both sides of the roadway.  The storm drain system consisted of splitting this corridor-long basin into sub-basins to improve runoff collection and disposal. 

HLA assisted in securing TIB funding, hosted structural meetings, and a public forum, provided topographic survey, design, Pacific Power pole removal, plans, specifications, estimate, construction observation and management, funding administration, and closeout.
