Title
Consider and take action on a resolution authorizing Amendment 2 to the Professional Services Agreement with Halff Associates, Inc. for the Lobit Park Phase 2 Project (PK2206) for additional engineering design services in an amount not to exceed $48,500 (Executive Director of Capital Projects)
Background:
Approval of this resolution will authorize Amendment 2 to the Professional Service Agreement with Halff Associates, Inc. for the Lobit Park Phase 2 Project (PK2206) for additional engineering services in an amount not to exceed $48,500. The additional services addresses design revisions, additional detention and drainage evaluations, civil design revisions, new pedestrian bridge design, landscape architecture revisions, and restroom additional coordination required to advance the Phase 2 design.
The Lobit Park Phase 2 design has required extensive coordination and drainage evaluation to develop a feasible design within the existing site and downstream drainage constraints. The drainage work has involved evaluating multiple detention pond configurations and the variance requirements associated with each option. Based on preliminary modeling results, the City directed Halff to proceed with an option that did not require expansion of the proposed detention pond; following the 60% design review, City comments required additional evaluation and revisions to the proposed drainage approach to meet development requirements. Halff subsequently evaluated additional detention and drainage options, prepared a revised detention pond layout and calculations, and coordinated the resulting site revisions.
The drainage revisions affected other portions of the park layout. Civil engineering revisions include regrading the pond, parking lot, field, and restroom areas, as well as revisions to the drainage and dimensional-control plans. Additional site planning and landscape architecture work required to incorporate the revised detention pond and related changes. ...
