Detention Pond Analysis & Design

Residential Detention Engineering in Houston

Stormwater detention is often required for residential developments in the Houston area to manage increases in runoff caused by new impervious surfaces. Harris County Flood Control District and the City of Houston have established detention requirements that residential developments must meet before permits are issued.

ACAR Engineering provides comprehensive detention pond design, analysis, and PE-sealed engineering reports for residential projects — from single-lot evaluations to subdivision-scale detention systems.

Our Detention Engineering Services Include:

✓Hydrologic analysis — existing and proposed stormwater runoff calculations
✓Hydraulic analysis — inflow/outflow modeling and routing
✓Detention pond sizing & design — volume calculations and pond geometry
✓Outlet/control structure design — where applicable to the project scope
✓HCFCD compliance — designed to Harris County Flood Control District criteria
✓PE-sealed engineering report — signed and sealed detention analysis report

Harris County Detention Requirements: Harris County Flood Control District requires that new residential development not increase peak stormwater runoff beyond pre-development conditions for the 2-year, 10-year, and 100-year storm events. ACAR Engineering designs detention systems to meet these specific HCFCD criteria.

When Detention Analysis is Required:

→ Residential subdivision or multi-lot development
→ Harris County or City of Houston detention review required
→ Development increases impervious cover above threshold

What is included in a detention pond engineering report?

A detention engineering report typically includes hydrologic analysis (rainfall data, runoff calculations), hydraulic routing, detention pond sizing, outlet structure design where applicable, and compliance documentation for the applicable jurisdiction. ACAR Engineering provides PE-signed and sealed reports suitable for permit submission.

What storm events are used for detention design in Houston?
