Rural Land Development: Barndominiums, Detention Ponds & SWPPP

As rural and suburban areas of Texas, North Carolina and Florida grow, more owners are building barndominiums, large-lot subdivisions and ranch properties.

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.

Barndominium Engineering

A structural engineer typically provides:

• Foundation design for the site soils

  
  

• Anchor bolt and column base coordination with the metal building supplier

  
  

• Wind load design under the locally adopted code

  
  

Permit rules vary from place to place. Some rural counties have few building permit requirements, but lenders and insurers often still ask for engineered plans.

In Brazoria and Galveston counties, JRH supports TDI windstorm (WPI-8) certification.

When Is a Detention Pond Required?

• When a project adds impervious cover such as roofs, drives and parking

  
  

• When county or city rules limit post-development runoff to pre-development rates

  
  

• In the City of Houston, IDMS-2025-01 requires 0.8 acre-feet per acre of proposed impervious area for many non-single-family tracts of 20 acres or less; nearby counties set their own criteria

  
  

A civil engineer maps the drainage areas, models the runoff and sizes the pond. The engineer also designs the outlet, spillway and grading.

When Is a SWPPP Required?

• Texas: sites disturbing 1 acre or more, or part of a larger common plan, need TCEQ Construction General Permit coverage and a SWP3 before construction

  
  

• North Carolina: erosion and sedimentation control plans are required for land disturbance of more than 1 acre under G.S. 113A-57

  
  

• Florida: sites of 1 acre or more need FDEP construction stormwater coverage

  
  

Project: FM 149 Private Road Neighborhood, Grimes County, TX

• 140-acre private road neighborhood near Anderson, Grimes County

  
  

• Coordination with the county, TxDOT and the fire marshal

  
  

• Read the Phase 1 case study

  
  

Challenges

• A limited construction budget needed funding before lot sales began

  
  

• Detention pond storage was needed on a tight budget

  
  

Objectives

1. Generate construction capital early.

   
   

2. Meet drainage rules at low cost.

   
   

Solutions JRH Engineering Provided

• Land development and civil engineering: subdivision planning, site design and drainage

  
  

• Eight FM 149 frontage lots subdivided and sold first to fund construction

  
  

• An existing stock tank converted into a compliant detention pond by lowering the water surface and adding an outfall

  
  

• Individual wells and septic systems for each lot (septic design by others)

  
  

Results:

• Construction capital generated before major infrastructure work

  
  

• No new detention pond construction

Frequently Asked Questions

Does a barndominium need engineered plans?

Often; many jurisdictions, lenders and insurers require them, especially in high-wind areas.

Does a rural property need a detention pond?

It may, if the project adds impervious cover and local rules limit runoff.

When is a SWPPP required?

Generally when construction disturbs 1 acre or more, or is part of a larger common plan.

Can an existing stock tank serve as a detention pond?

Sometimes; at FM 149, a stock tank was converted with a lowered water surface and new outfall.

Does JRH Engineering design septic systems?

No, septic design is by others; JRH shows the preliminary septic area on the site plan.

Does JRH Engineering obtain building permits?

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