ENGINEERING REVIEW has moved to the Public Works Department!

The Public Works Department welcomes the Engineering Review Division in 2019.  Engineering Review  promotes quality community growth and development in the City of SeaTac through administration of all engineering plans submitted to the City for development permits. The Division reviews site engineering plans to include clearing, grading, paving, stormwater management system, roadway, right-of-way use and much more. The Engineering Review Division is also responsible for review and approval of all utility permits in the right-of-way, haul permit applications along with any other construction activities such as lane closures, traffic control and detour plans. Ali Shasti, P.E., MSCE, a professional engineer registered in State of Wash., manages the division.
