Consideration, discussion, and possible acceptance of the Drainage Advisory Committee’s recommendation to approve expenditure of 2018 General Obligation (GO) Bond funds to replace a retaining wall along Liberty Trail
End
Background:
The case was brought before the Drainage Advisory Committee on July 28th, 2025 for construction funds. The Committee voted 6-0 to recommend approval of expenditure of funds.
This project is located on Liberty Trail that runs along the north side of the Creek Turnpike in Broken Arrow.
The wall is a segmental block retaining wall that has visible signs of distress and potential failure, per an evaluation completed by McGuire Civil Engineering Services, LLC in May of 2025. A pronounced bulge has developed in a section of the wall, where several blocks have dislodged from the earth fill behind them. The wall is located downslope from the turnpike approximately 35 feet away, with no evident drainage infrastructure to intercept runoff from the road. Runoff flows appear to be flowing directly toward the wall. The wall also does not have any weep holes or gravel backfill zone, which are standard design requirements per the evaluation provided by McGuire Civil Engineering Services, LLC.
The approximate length of the wall is 1,000 linear feet and the height varies from 8 inches to 7.5 feet in height.
Staff is requesting $500,000.00 of the 2018 General Obligation Bond Proposition 6 for funds to construct a new retaining wall. The project will be designed in-house.
This area flows to Elm Creek.
Cost: $500,000.00
Funding Source: 2018 General Obligation Bond, Proposition 6
