ADMINISTRATIVE COMMENTS:

 

Two relatively small projects similar in scope to the Timber Creek Erosion Repair - Phase 2 Project have been identified by staff as priorities due to existing eroded conditions and adjacent construction activities. Staff is recommending both small design projects be added to the Timber Creek Erosion Repair - Phase 2 PSA with Halff Associates as the work is very similar in nature and relatively specialized. The first project, Valley Vista Outfall, is to repair severe erosion occurring in a storm sewer outfall on Corporate Drive near Regency Drive compromising the gabion work completed several years ago on Timber Creek. The second project, Fish Hatchery Road Bridge, is to repair minor damage to the Fish Hatchery Road Bridge that occurred during the Lake Lewisville spillway event in May 2015. The USACE has requested the erosion protection around the bridge abutments be repaired to help assure bridge stability and prevent additional damage in the event of another flood during the pending dam repair.

 

RECOMMENDATION:

 

That City Council approve the agreement as set forth in the caption above; and authorize the City Manager or her designee to execute the agreement.
