Storm Season Tests Every Site's Drainage

Severe storm outlooks across Texas, North Carolina and Florida around Mother's Day weekend 2026 were another reminder: drainage design is decided long before the rain arrives.

When a site floods, the problem often traces back to grading, storage or outfall decisions made during design.

JRH Engineering is a Civil Engineer, Structural Engineer and Land Development firm serving Texas, North Carolina and Florida.

JRH guiding principles are: Engineering Excellence. Delivered on Time. Built on Value.

What Happens Without Proper Stormwater Design

• Water ponds on pavement and against buildings

  
  

• Runoff increases flooding on neighboring and downstream properties

  
  

• Erosion and sediment leave the site during construction

  
  

• Agencies issue violations that require retroactive permits and redesign

  
  

What Good Stormwater Design Includes

• Grading that moves water away from buildings to a planned outfall

  
  

• A detention pond sized to the governing criteria

  
  

• Storm sewer and inlet design for the site's runoff

  
  

• Floodplain analysis and fill planning where the site is in a mapped flood zone

  
  

• A construction SWPPP with erosion and sediment controls

  
  

Before You Buy or Build

• Check the FEMA flood zone and local drainage criteria

  
  

• Confirm the outfall can legally accept the flow

  
  

• Budget land for the detention pond early

  
  

Project: Sillman St. Office Warehouse, Sealy, TX

• Single-occupant office warehouse in Sealy, Austin County

  
  

• Site with significant grade change and a floodplain at the rear

  
  

• Read the full Sillman St. case study

  
  

Challenges

• Grade changes across the property complicated drainage

  
  

• The rear floodplain limited usable land

  
  

• The natural access point would have required a railroad crossing permit

  
  

Objectives

1. Maximize usable building area despite the floodplain.

   
   

2. Resolve access without railroad permitting delays.

   
   

3. Remove dependence on municipal utilities.

   
   

Solutions JRH Engineering Provided

• Civil engineering site, grading and drainage design

  
  

• The detention pond placed in the rear floodplain area, turning a constraint into stormwater storage

  
  

• Access routed away from the adjacent railroad crossing

  
  

• A private well and septic approach in place of municipal utility extensions

  
  

Results:

• Front and middle of the property preserved for warehouse operations

  
  

• Railroad crossing permit avoided

  
  

• Utility timelines removed from the critical path

  
  

Stormwater Rules in Texas, North Carolina and Florida

Texas

• Construction disturbing 1 acre or more needs TCEQ Construction General Permit coverage, with a SWP3 before construction; see 2026 Houston Flood & Stormwater Solutions.

  
  

North Carolina

• Erosion control plans for more than one acre need approval at least 30 days before work under G.S. 113A-57.

  
  

Florida

• Sites disturbing 1 acre or more need FDEP construction permit coverage; check flood zones on FEMA's Flood Map Service Center.

  
  

Frequently Asked Questions

Why do sites flood during heavy storms?

Often because of grading, storage or outfall problems from design or construction.

What is a SWPPP?

A stormwater pollution prevention plan that controls erosion and sediment during construction.

When does a Texas site need TCEQ stormwater coverage?

Generally when construction disturbs 1 acre or more.

Can a floodplain area hold a detention pond?

Sometimes; at Sillman St., the rear floodplain became the detention pond area.

When should drainage be checked on a new property?

During due diligence, before closing on the land.

Does JRH Engineering obtain building permits?

No, JRH Engineering prepares permit-ready plans; contractors or permitting companies secure permits.
