Civil engineering for a 16.1-acre office condo park in Harris County
JRH Engineering provided complete civil engineering design for a 16.1-acre office condo business park in Katy, Texas, with access to a public road. The site presented a significant grade change on one side — a challenge that could have required costly earthwork and extended the construction timeline. JRH accelerated the project by reusing previously approved detention plans and resolving the grade change with a targeted retaining wall solution rather than site-wide regrading.
AT A GLANCE
Site civil design
Full site civil design including grading, paving, and public road access
Existing approved detention plans reused — eliminating redesign time and accelerating permitting with the City of Katy
Retaining wall installed on the challenging grade-change side of the site — faster and less costly than regrading the full site
Floodplain fill mitigated on-site; full site area preserved for development
Utility infrastructure
Water and sanitary sewer tied into the City of Katy existing municipal system
No utility extension required — existing infrastructure accessible from the site
Stormwater and drainage
Detention plans reused from a previously approved project — same criteria, same agency, same standards — eliminating a full design cycle and compressing the city review timeline
Floodplain fill mitigation handled entirely on-site
Storm sewer approved by the City of Katy
Permitting and agency coordination
City of Katy permitting accelerated by reusing previously approved detention design — reviewers familiar with the approach, fewer comments, faster approval
Retaining wall solution resolved the grade change issue in design before submittal — no field conditions requiring plan revisions mid-review
The Challenge — two problems with faster answers available
The Cane Island site had two issues that needed resolving before construction could start: a significant grade change on one side of the property, and the time cost of designing a new detention system from scratch. Both had faster, smarter solutions available — if the engineer knew where to look.
JRH’s Approach — reusing an approved design and walling the grade
JRH recognized that previously approved detention plans from a comparable Katy project could be applied here — same jurisdiction, same drainage criteria, same approval process. Reusing those plans eliminated an entire design phase and shortened the city review timeline because the approach was already familiar. For the grade change, rather than regrading the entire site, JRH specified a retaining wall on the affected side. One targeted solution resolved the topographic constraint without disrupting the rest of the site.
The Results
01
Permitting accelerated by reusing previously approved detention plans — no redesign cycle, faster city review
02
Grade change resolved with a targeted retaining wall — significantly less earthwork cost than full-site regrading
03
Full 16.1 acres preserved for development — floodplain mitigation handled on-site

Frequently Asked Questions
What was the main engineering challenge on the Cane Island Pkwy. project?
The 16.1-acre office condo business park had a significant grade change on one side of the property, and designing a new detention system from scratch would have added time and cost.
How did JRH Engineering accelerate the Cane Island Pkwy. project?
JRH reused previously approved detention plans from a comparable Katy project to eliminate a full design cycle, and resolved the grade change with a targeted retaining wall instead of regrading the entire site.
What were the results of the Cane Island Pkwy. project?
JRH accelerated City of Katy permitting by reusing approved detention plans, resolved the grade change at a fraction of the cost of full-site regrading, and preserved the full 16.1 acres for development.
