Water Quality Standards

Impervious Cover Limit
No citywide impervious cover cap; drainage systems must accommodate design storm flows per City of Pearland Drainage Criteria Manual; Pearland's low-lying topography and expansive clay soils create significant drainage challenges
On-Site Treatment Required
No
Detention Required
Yes
Detention Standard
Detention required to limit post-development peak flows to pre-development levels for 2-, 10-, 25-, and 100-year storms per City of Pearland Drainage Criteria Manual; low-lying terrain requires conservative detention sizing; Hurricane Harvey significantly affected design assumptions
Turbidity Standard
No numeric NTU limit; discharges must comply with TCEQ TXR150000 and not degrade Brazos River, Clear Creek, or Chocolate Bayou

Local SWPPP / Drainage Plan

Local Plan Required
Yes
Plan Name
SWPPP per TCEQ TXR150000; drainage report required for local permit
PE Stamp Required
Yes
Drainage study prepared by a Texas PE required for grading permits. Pearland experienced catastrophic flooding during Hurricane Harvey (2017) and has since updated drainage standards. Many areas of Pearland are low-lying and prone to flooding — detention sizing must account for post-Harvey revised rainfall frequencies. Projects should reference the latest NOAA Atlas 14 Volume 11 data for Southeast Texas.

Local Inspection Requirements

Requirements
City of Pearland Engineering and Public Works inspects grading permits at rough grading, drainage infrastructure installation, and final stabilization. Hurricane season requires heightened BMP maintenance June–November.
Inspector Qualification
No city-specific certification required beyond TCEQ SWPPP requirements

Special Overlay Zones

Clear Creek Watershed (Harris County Flood Control District)
Trigger: Development draining to Clear Creek or its tributaries, which straddle the Harris/Brazoria county line
Restriction: Coordinate with Harris County Flood Control District (HCFCD) for projects with significant drainage impact on Clear Creek; HCFCD has design criteria for channel connections; post-Harvey watershed studies revised design flows
Brazoria County Drainage District Channels
Trigger: Development connecting to or crossing Brazoria County Drainage District maintained channels
Restriction: Coordination required with Brazoria County Drainage Districts for outfall connections; district drainage criteria may differ from city criteria
FEMA Special Flood Hazard Area
Trigger: Development within extensive FEMA-mapped 100-year floodplain in Pearland (significant portions of the city)
Restriction: Floodplain development permit required from City of Pearland Floodplain Administrator; no net fill without compensatory storage; FEMA maps were revised post-Harvey in many areas

Jurisdiction Notes

Pearland is one of the fastest-growing cities in Texas and the Houston metro, located in Brazoria County south of Houston. The city's flat, clay-heavy soils and low-lying topography create significant drainage challenges. Hurricane Harvey (2017) devastated portions of Pearland and revealed inadequacies in the regional drainage system. The city has since invested heavily in drainage infrastructure improvements. Detention pond design in Pearland should use the latest post-Harvey hydrologic guidance. The city spans both Brazoria and Harris counties, with drainage infrastructure coordinated between multiple agencies.

Remember: These local requirements are in addition to the TCEQ state construction permit. Both must be satisfied before breaking ground.
