Hometown Bank — Class A Bank Replacement Civil Engineering in Galveston, TX

Demolition and new Class A construction on a coastal floodplain site
JRH Engineering provided complete civil engineering design for the demolition of an existing bank and construction of a new Class A building in Galveston, Texas. The coastal site required compliance with floodplain elevation mandates that significantly raised the finished floor — necessitating a full redesign of the drive-through configuration. JRH eliminated the need for a traditional detention pond entirely by designing the site with permeable paving, qualifying for a detention exemption and delivering a cleaner, faster approval with the City of Galveston.
AT A GLANCE
Site civil design
Full site civil design for demolition and new Class A bank construction
Permeable paving specified across the site — qualifying the development for a detention exemption under City of Galveston criteria
Floodplain elevation mandate required raising the finished floor significantly — the drive-through configuration was redesigned to accommodate the elevated floor while maintaining functional vehicle access
All floodplain and elevation challenges resolved in design before submittal — a clean first submission to the city
Utility infrastructure
Water and sanitary connected to the City of Galveston municipal system
Utility connections designed and coordinated concurrently with site and floodplain design
Stormwater and drainage
Permeable paving selected as the drainage solution — stormwater infiltrates through the paving surface, eliminating surface runoff and qualifying the site for a detention exemption
Traditional detention pond eliminated entirely — no pond design, no pond construction, no pond permitting
City of Galveston drainage approval secured through the permeable paving exemption
Permitting and agency coordination
City of Galveston permitting streamlined by eliminating detention from the scope — fewer design elements, a simpler permit package
Floodplain elevation and drive-through redesign resolved before submittal — no mid-review surprises
Complete submission package on first submittal
The Challenge — a raised finished floor and a drive-through that still has to work
Coastal Galveston floodplain requirements are among the most demanding in Texas. Raising the finished floor to meet base flood elevation mandates is not optional — but it creates real design challenges for a bank drive-through, where the grade relationship between the parking lot, drive-through lanes, and the building entrance has to work for customers and vehicles. On top of the elevation challenge, the site needed a detention solution in a location where a traditional pond would consume valuable commercial land.
JRH’s Approach — infiltrate instead of detain
JRH identified permeable paving as the answer to the detention problem. By using permeable paving across the site, stormwater infiltrates on-site rather than running off, qualifying the development for a City of Galveston detention exemption. No pond, no pond permitting, no pond construction cost. The elevated finished floor and drive-through redesign were resolved in the design phase before the first submittal, so the city received a complete, conflict-free package.
The Results
01
Detention pond eliminated through permeable paving — City of Galveston detention exemption qualified and approved
02
Coastal floodplain elevation requirements met — finished floor raised to the base flood elevation with the drive-through reconfigured in design
03
Clean first submission to the City of Galveston — all elevation and drainage challenges resolved before submittal

Frequently Asked Questions
What was the main engineering challenge on the Hometown Bank replacement project?
Galveston's coastal floodplain elevation mandates required raising the finished floor significantly, which meant redesigning the drive-through configuration, while the site still needed a workable detention solution.
How did JRH Engineering eliminate the need for a detention pond at Hometown Bank?
JRH specified permeable paving across the site, allowing stormwater to infiltrate on-site and qualifying the development for a City of Galveston detention exemption, eliminating pond design, construction, and permitting entirely.
What were the results of the Hometown Bank project?
JRH eliminated the need for a traditional detention pond through the permeable paving exemption, met the coastal floodplain elevation requirements with a redesigned drive-through, and delivered a clean first submission to the City of Galveston.
