City Council awarded a $97,196 contract package for new and expanded flumes in the Shannon Creek subdivision to address flooding reported in 2022.

A $293,137 contract package was approved for BRINSAP channel repairs, including sediment removal and erosion control to protect local bridge infrastructure.

The council approved an $84,300 contract amendment with Parkhill, Inc. to redesign stormwater routing at Katherine Rose Memorial Park following an expanded flood study.

The City of Mansfield is moving forward with multiple stormwater and drainage infrastructure improvements, approving contracts on June 8 to address residential flooding, protect bridge infrastructure, and manage runoff in municipal spaces. To mitigate residential flooding, the City Council approved a $97,196.56 contract package for flume improvements in the Shannon Creek subdivision. The construction contract was awarded to Alliance Construction and Concrete Services, LLC, alongside supporting surveying and material testing contracts. According to city staff, the project follows a drainage study prompted by flooding in 2022. The improvements will add a completely new flume and expand another to handle drainage that currently lacks capacity and risks flowing through residential properties. Staff noted during the meeting that drainage projects are prioritized based on severity, frequency, and whether homes or major roadways are impacted. In a separate item, the council authorized $293,137.19 for in-channel repairs across seven locations as part of the BRINSAP program, which involves periodic TxDOT evaluations of waterway crossings. Awarded to Premier Site Services, LLC for construction, the project involves removing built-up sediment and debris from under bridges and installing new measures to protect against erosion and scour. A staff member noted that these preventative maintenance efforts will protect bridge infrastructure from substantial flood damage and fulfill the city's local match commitment to TxDOT regarding the Walnut Creek Bridge replacement. Additionally, the council approved an $84,300 contract amendment with Parkhill, Inc. to redesign stormwater management at the Katherine Rose Memorial Park. Following requests during the city permit review process, an expanded flood study was conducted to account for water flowing from Broad Street, under railroad tracks, and through the park site into Walnut Creek. The contract amendment allows engineers to reroute the stormwater through the site, preventing the loss of planned recreational courts that would otherwise be impacted by the drainage flow.
