Sub-acre infill townhouse development in Harris County
JRH Engineering provided complete civil engineering design for an infill townhouse development on less than one acre in the City of Houston, in a roadside ditch neighborhood requiring connections to water, sanitary and storm infrastructure. On a sub-acre site every square foot of surface area has direct development value, so JRH designed an underground detention system that kept the entire surface available for the project and qualified for a favorable detention rate that saved both cost and schedule time.
AT A GLANCE
Site civil design
Full site civil design for sub-acre infill development — maximizing every square foot of surface area for the townhouse footprint
Underground detention system designed to eliminate any surface pond — 100% of surface area preserved for development
Project scope fell under the City of Houston’s threshold for a more favorable detention rate, qualifying the design for reduced storage requirements and lower construction cost
Full plan-and-profile drawings produced for all utility connections in the City of Houston ROW
Utility infrastructure
Water, sanitary and storm connections designed to City of Houston ROW standards
Plan-and-profile utility drawings produced for city ROW submission — complete package on first submittal, reducing review cycles
Roadside ditch neighborhood utility tie-in designed to city standards without requiring major ditch modifications
Stormwater and drainage
Underground detention selected over a surface pond — on a sub-acre site, surface detention is not viable without sacrificing development value
Project fell under the City of Houston detention threshold — favorable rate applied, reducing required detention volume and construction cost
Storm connection designed to the existing roadside ditch infrastructure
Permitting and agency coordination
Single-agency permitting through the City of Houston — complete submission package on first submittal
Plan-and-profile ROW drawings submitted with the permit package — city review proceeded without requests for additional information
The Challenge
Infill development on sub-acre sites in Houston is a precision exercise. There is no room for a surface detention pond — it would consume the entire development footprint. The project also required city ROW utility connections in a roadside ditch neighborhood, which demands complete, accurate plan-and-profile drawings on the first submission or review delays compound quickly.
JRH’s Approach
Underground detention was the only viable drainage solution on a site this size, and JRH sized it to fall under the City of Houston’s threshold for a more favorable storage rate — reducing both the detention volume required and the construction cost. Full plan-and-profile ROW drawings were produced for every utility connection, so the City of Houston had everything it needed to move through review without back-and-forth requests.
The Results
01
100% of surface area preserved for development — underground detention eliminated any surface pond footprint
02
Favorable detention rate qualified by keeping the project under the City of Houston threshold — reduced volume and construction cost
03
Complete ROW submission on first submittal — no city review delays from incomplete utility drawings

Frequently Asked Questions
What was the main engineering challenge on the Beckley Rd. townhouse project?
Infill development on a sub-acre site in Houston left no room for a surface detention pond, and the project required City of Houston ROW utility connections that demanded complete, accurate plan-and-profile drawings on the first submission.
How did JRH Engineering solve the drainage constraint on this project?
JRH designed an underground detention system that eliminated any surface pond, preserving 100% of the site's surface area for development, and sized it to qualify for the City of Houston's favorable detention rate.
What were the results of the Beckley Rd. townhouse project?
JRH delivered a fully permitted infill townhouse development with 100% of the surface area available for construction, a favorable detention rate, and a complete ROW submission accepted on first submittal with no city review delays.
