RECOMMENDATION
Recommendation
That Council adopts a resolution (Attachment II) authorizing the City Manager to execute an Amendment to the Professional Services Agreement (PSA) with Langan Engineering and Environmental Services (Langan) increasing the agreement by $73,400, for a total contract amount not-to-exceed $293,400.

SUMMARY
On March 26, 2019, Council approved a PSA with Langan for the geotechnical investigation and report for the La Vista Park Project in an amount not-to-exceed $220,000. The final geotechnical report by Langan will be completed in June 2020.
The original contract scope of work included ten exploratory boring locations spread out across the approximately 50-acre site given the existence of a landslide area on the property. Staff is recommending five additional exploratory borings directly under the proposed landslide repair area to obtain additional information. The information gathered from these borings could potentially reduce the required width, depth, and length of the proposed slide repair area, resulting in a cost reduction to the required landslide repairs. The total added scope of work is estimated at $73,400 and staff recommends that Council approve increasing Langan’s PSA by this amount, for a not-to-exceed total contract amount of $293,400.
