Costello serves as both Development Engineer and District Engineer for this 84-acre special purpose district located at the northeast corner of Pin Oak Road and IH-10. The District lies within the city limits of the City of Katy, Texas. This project is a multi-commercial use development.

Costello originally provided feasibility research and worked with the City of Katy and the developers to determine utility capacity, investigated driveway access permits, worked with architect and developer to determine project goals and design schedules, and met with dry utility providers to plan future needs. Additionally, a master drainage plan was formulated and submitted to the City of Katy for review and approval.
Due to new regulations after Hurricane Harvey, Costello provided a retention study in addition to the design of two detention basins with a control structure. This is one of the ﬁrst post-Harvey retention studies submitted for review that is within the Barker Watershed.

A unique feature of this project included the design of a traﬃc circle in the middle of the District, where two major cross streets meet. The project also includes 4,800 LF of public streets, 4,000 LF of water distribution lines, 1,700 LF of 8” gravity sewer collection lines, and 2,500 LF of 24”-60” storm sewers with associated inlets. Additional work included assisting the developers with access and public and private driveway permits to tie into US-90 and the IH-10 feeder road at multiple locations, including TxDOT coordination.

Project Size and Cost

84 acres
Estimated construction cost $3.6M

Unique Project Attributes

A public traffic circle is located connecting the two minor collector cross streets through the project
The detention improvements also required a retention feature to comply with post-Harvey drainage infrastructure

Challenges Faced

Work with TxDOT to have two locations of driveway permits to the IH-10 westbound frontage road allowed and permitted when the locations were within an access denied zone
Work with both Harris and Fort Bend Counties as the county line passes directly through the project
Developing and building a drainage outfall strategy with the developer as the drainage outfall to Cane Island Creek was over three blocks away and non-contiguous to the project boundary

Resolutions & Results

Worked with TxDOT Houston and Austin to have access rights granted for the driveways and public streets to access IH-10
Assisted to coordinate terms of construction for the developer to bind an agreement with a downstream landowner to secure a critical drainage easement path to drain the 84 acres effectively
