Regional Detention Credits Save Texas Site Acreage
As September 2025 gave way to a fast-moving 2026 development cycle, Texas developers have kept running into the same site-planning problem: the pond eats the profit.
JRH Engineering is a licensed civil, structural, and land development engineering firm serving Texas, North Carolina, and Florida.
JRH guiding principles are: Engineering Excellence. Delivered on Time. Built on Value.
Below is a look at how a Katy, Texas civil engineering project avoided an on-site detention pond entirely — and what that decision was worth in developable land.
The Project
JRH Engineering delivered full civil engineering design for an 11.25-acre office condo business park in Katy, Texas, with direct frontage access to Interstate 10.
Key project facts:
Location: Katy, Harris County, Texas
Site size: 11.25 acres
Access: New public road with TxDOT-coordinated I-10 connection
Permitting agencies: TxDOT, Brookshire-Katy Drainage District (BKDD), City of Katy
Services: Civil engineering, site development, utility design, land development coordination
The Challenges
An office condo park along an interstate corridor is generally only as valuable as the square footage it can lease.
A few site conditions made this a harder-than-average drainage decision:
Land consumption risk.
A traditional on-site detention pond on an 11.25-acre tract could have removed a meaningful share of developable, leasable acreage.
Added design and construction time.
Pond design typically means a separate design track, a separate construction phase, and a separate maintenance obligation.
Multi-agency coordination.
Storm sewer approval needed sign-off from both BKDD and the City of Katy — two review processes that do not automatically move on the same timeline.
State highway access.
The new public road required TxDOT coordination for I-10 access, which is one of the more involved approval processes in the greater Houston market.
Floodplain fill considerations.
Any fill placed in the floodplain needed to be resolved without triggering additional off-site agency review.
The Objectives
The development team asked JRH Engineering to help solve for:
Maximizing developable and leasable acreage across the full 11.25-acre site
Avoiding a pond footprint that could reduce the site's income potential
Keeping TxDOT, BKDD, and City of Katy approvals moving on parallel — not sequential — timelines
Resolving floodplain fill requirements without extending the permitting schedule
The Solutions JRH Engineering Provided
Regional Detention Instead of an On-Site Pond
Rather than designing a traditional detention pond, JRH Engineering worked with the development team to pursue regional detention credits through the Brookshire-Katy Drainage District.
This approach can, in projects like this one:
Remove the need for pond design, construction, and long-term maintenance
Free up land that would have otherwise gone to stormwater storage
Shift the site's drainage compliance to an existing regional facility rather than a new one built on the tract
On-Site Floodplain Fill Resolution
Floodplain fill mitigation was handled directly within the site design, which helped avoid extra coordination outside the project boundary.
Parallel Agency Review
Instead of waiting on one agency before starting the next, JRH Engineering coordinated:
TxDOT review for the new public road and I-10 access
BKDD and City of Katy storm sewer approval, run at the same time
Utility tie-ins to the City of Katy's existing water and sanitary sewer infrastructure
Running these processes in parallel is intended to help prevent any single agency from becoming the bottleneck for the entire schedule.
The Result
The full 11.25 acres remained available for development — no acreage lost to an on-site pond
TxDOT, BKDD, and City of Katy approvals moved forward together rather than in sequence
Floodplain fill mitigation was resolved without additional off-site review

Is Regional Detention an Option Outside of Katy, Texas?
Regional detention credit programs are not available everywhere, and availability can depend on the drainage district or municipality involved.
Texas: Many Houston-area drainage districts, including BKDD, offer some form of regional detention participation for qualifying sites.
North Carolina: Some Piedmont-region counties and municipalities maintain regional stormwater programs, though requirements vary by jurisdiction.
Florida: Regional and shared detention approaches exist in parts of the state, typically coordinated through county or water management district review.
A civil engineer with land development permitting experience in the applicable jurisdiction can help confirm what's available for a specific site.
