AGENDA CAPTION:

Consider action on a Resolution approving an agreement between the Town of Addison and Halff Associates, Inc. for White Rock Creek Drainage Basin Stormwater Infrastructure Assessment and authorizing the City Manager to execute the agreement in an amount not to exceed $216,000.

BACKGROUND:

The purpose of this item is to approve a Professional Services Agreement (PSA) with Halff Associates, inc. for stormwater infrastructure condition assessment of the White Rock Creek drainage basin.

During the FY23-24 budget process, a recurring decision package for $450,000 was approved to perform routine maintenance of the Town’s stormwater infrastructure as well as inspect each of the eight drainage basins on an annual rotation.

This assessment will identify infrastructure that requires cleaning and/or repairs.

The scope of this PSA is generally:

•   Television Inspection (CCTV) of Storm Drains
•   Access Point Inspections
•   Recommendations for Corrective Action
•   Stormwater System Repair Summaries
•   Updating of GIS to match actual field-verified assets

The White Rock Creek Basin contains approximately 31K LF of storm drains, 7 manholes, and 105 inlets.

Halff Associates was chosen for its industry expertise, excellent reputation, and proven track record with the Town. Halff completed the Stormwater Master Plan for the Town to identify Capital Improvement Projects in 2017.

The funding for these services will come out of the FY24 stormwater budget.

RECOMMENDATION:

Staff recommends approval.
