BACKGROUND The Interurban Ave S project is in the final phase of constructing improvements to the entire corridor between 42nd Ave S and 1 -405. The improvements will include curbs, gutters, sidewalks, illumination, storm drainage, street reconstruction, and other urban roadway improvements. Several environmental permits were required for construction, including a Shoreline Permit, NPDES, and a King County Sewer Discharge Permit. Each environmental permit included certain conditions that were required to be met as well as regular monitoring and reporting of activities. Widener & Associates provided support for obtaining the permits and have and will continue to monitor compliance during construction. ANALYSIS Construction activities have exposed contaminated groundwater and soils that have specific requirements for disposal. The contaminants have caused the contractor to modify construction methods. The original contract with Widener & Associates did not include coordination efforts to deal with contaminated materials, but they have the expertise and experience to assist City staff in this effort. Contract Amendment No. 1, including the scope of work and an estimate of fees, has been prepared to perform the additional compliance monitoring to dispose of contaminated materials properly. BUDGET AND BID SUMMARY Contract Amendment No. 1 with Widener & Associates is for $37,280.09, making the total contract amount $73,019.29. The $1,139,675.00 contingency will be used for this Amendment and to date, after this amendment, there is a balance of $363,571.80. RECOMMENDATION Council is being asked to approve Contract Amendment No. 1 with DGK, Inc. in the amount of $37,280.09 for construction management environmental compliance support and consider this item on the Consent Agenda at the July 20, 2015 Regular Meeting.

Design has attempted to minimize the land encroachment but these remaining small amounts are needed in order to avoid significant impacts to the levee. The City continues to work with the property owner but this ordinance will provide the authority to condemn the property should negotiations fail. The owners have been notified of the opportunity for public hearing. UNANIMOUS APPROVAL. FORWARD TO JULY 27, 2015 COMMITTEE OF THE WHOLE FOR PUBLIC HEARING. 101
