Stormwater Engineer: Delivering Site Improvements in Frisco, Texas
Stormwater design is more than a regulatory requirement—it’s a cornerstone of resilient urban infrastructure. In fast-growing cities like Frisco, Texas, where rainfall and urban sprawl intersect, stormwater engineers play a vital role in protecting both the built and natural environments.
RSP Engineers recently completed stormwater site improvements in Frisco Tx. This blog shares how our team delivered effective solutions that align with Frisco's standards, improve site drainage, and reduce flood risk for years to come.
What Are Stormwater Site Improvements?
Stormwater site improvements refer to the civil engineering design and construction of systems that manage how water flows across, infiltrates, and exits a developed property. In Frisco, these improvements must meet local, county, and state standards to ensure public safety, erosion control, and environmental protection.
The stormwater systems typically include:
Surface grading to direct runoff
Curb inlets and catch basins
Underground storm sewer systems
Detention ponds and outfalls
Sediment and erosion control measures
Project Overview: Stormwater Improvements in Frisco, TX
Project Site 1:
This commercial property required a full stormwater management upgrade to meet updated Frisco drainage standards. Our stormwater engineers provided:
Grading plan revisions to improve onsite conveyance
Storm drain system reconfiguration with updated inlets and underground piping
Drainage area maps and runoff modeling
Coordination with Frisco Public Works for utility conflict resolution
Erosion control measures during construction
Sealed engineering documents for permitting and contractor use
Project Site 2:
This adjacent project site included both residential and utility-focused drainage improvements. RSP Engineers led the following scope:
Stormwater basin analysis and retrofit
Upsizing of curb inlets and redirection of overland flow
Field coordination with geotechnical and environmental consultants
Implementation of TCEQ erosion control guidelines
Stormwater pollution prevention plan (SWPPP) review
Permitting package and as-built drawings post-construction
| Task | Details |
|---|---|
| Field Survey | Verified constructed elevations vs. design plans |
| As-Built Evaluation | Mapped revised drainage system components |
| ICPR Hydraulic Modeling | Simulated system performance under new invert elevations |
| Compliance Review | Assessed compatibility with Colin County, TXDOT, and FEMA standards |
| Engineering Report | Delivered findings and mitigation recommendations if needed |
Engineering Approach
At RSP Engineers, stormwater engineering is integrated from concept to construction. For both Frisco locations, our approach included:
Site-Specific Drainage Modeling
Using Texas-based rainfall intensities and rational method hydrology, we ensured storm sewer sizing was optimized for both performance and cost.Field-Focused Design Coordination
Collaborating closely with contractors and city reviewers, our engineers proactively addressed conflicts and expedited approvals.Future-Proof Design Strategy
We designed with both current and projected runoff in mind, ensuring that the site can handle infill or adjacent development over time.
Project Outcomes
Improved on-site and off-site drainage with no reported flooding during recent storms
Full City of Frisco stormwater compliance for both commercial and residential uses
Increased site value and reduced maintenance risk for property owners
Faster permitting due to complete and well-documented submittals
Why It Matters
Drainage systems are finely balanced. A small field change, like an invert elevation adjustment, can ripple across the entire network. By evaluating the impact early, RSP Engineers helped maintain the system’s integrity, minimized rework, and protected public infrastructure investments.

FAQ’s
-
Frisco enforces specific peak discharge and detention standards that often exceed minimum state code. Localized flooding history also informs plan reviewers’ scrutiny.
-
Yes. Any site that alters impervious area, grading, or utility layout must have a drainage plan sealed by a licensed Texas engineer.
-
They assess grading, review hydrologic conditions, ensure pipe networks are functioning as designed, and work with municipalities to get approvals.
