TC Jester Bridge


  • TC Jester Bridge

Project Description:

CivilTech provided construction plans and technical specifications for a new roadway and bridge structure for TC Jester Boulevard, from Ivy Falls Drive to Cypresswood Drive, extending a length of 0.5 miles. The project also included a new four-span bridge over Cypress Creek, equaling a total length of 460 feet. The new roadway is a four-lane concrete boulevard roadway with curb and gutter and storm sewers, with the right-of-way (ROW) varying from 100 feet to 120 feet. CivilTech was specifically selected for this project because of our extensive knowledge of Cypress Creek and its watershed, our H&H expertise, our structural abilities, and our successful past performance on difficult projects.

 

Major Design Considerations:

Floodway and 100-Year Floodplain Challenges.Since the entire project site was in either the floodway or 100-year floodplain, hydraulic impact analysis was required to determine the impacts to Cypress Creek due to fill in the floodplain and the impacts resulting from the added restrictions to conveyance in the floodway and floodplain due to the raised bridge structure. A single detention basin located on the North side of Cypress Creek was designed to provide the required mitigation for both fill in the floodplain and impacts to conveyance in Cypress Creek. The basin was also designed with full storm water quality features to ensure that pollutants in the stormwater run-off are not drained to Cypress Creek. The design was particularly difficult because Cypress Creek is a protected waterway and cannot be widened, realigned, slope paved, or otherwise changed from its natural state. In addition, a hydraulics impact study was performed to comply with the requirements and no adverse impact policy of the Harris County Flood Control District (HCFCD).

FEMA CLOMR & LOMR Applications. A FEMA Conditional Letter of Map Revision (CLOMR) and Letter of Map Revision (LOMR) was submitted and approved by FEMA.

Wetlands Delineation. The Wetlands Delineation study determined that over half an acre of wetlands would be affected, which required an Individual Permit from the US Army Corps of Engineers.
