Working around a single-access unit count limit in Pearland
JRH Engineering provided complete civil engineering design for the Afton Lake residential neighborhood in Pearland, Texas. The project faced a residential unit count constraint: fire marshal regulations capped the development at 30 units for a single access point. Rather than accepting that cap as the development’s ceiling, JRH added commercial reserve lots at the front of the property — converting underutilized frontage land into a higher-value land use and maximizing the overall tract value within the fire marshal’s access restrictions.
AT A GLANCE
Site civil design
Full civil design including residential lot layout, commercial reserve lots, grading, and access
Commercial reserve lots added at the front of the property — a higher-value land use for the high-visibility frontage area
Residential unit count held at 30 to comply with the fire marshal single-access threshold
Storm and sanitary routed to TxDOT infrastructure — simplifying the utility approval process
Permitting and agency coordination
City of Pearland, TxDOT, and BDD4 approvals pursued simultaneously
Fire marshal single-access unit count limit addressed in the design — the 30-unit cap built into the layout
TxDOT utility routing simplified city and drainage district coordination
The Challenge — why a 30-unit cap limits more than the unit count
A fire marshal cap of 30 residential units for a single access point limits the revenue potential of a residential-only development. The frontage land along the access road is the most visible and accessible portion of the site — using it for residential lots at the same density as the interior is not the highest and best use.
JRH’s Approach — putting a different land use on the frontage
JRH recommended adding commercial reserve lots at the front of the property — land uses that are not subject to the residential unit count cap and that carry higher per-square-foot value than residential lots. The fire marshal restriction stayed in place for the 30 residential units in the interior, but the commercial frontage added development value that the residential-only approach left on the table.
The outcome: a fully permitted mixed residential and commercial development, with maximum value extracted from the tract within the fire marshal’s access restrictions.
The Results
01
Commercial reserve lots added at the frontage — a higher-value land use extracted from the most visible portion of the site
02
Fire marshal unit count restriction accommodated in design — the 30-unit residential cap was built into the layout
03
Storm and sanitary routed to TxDOT infrastructure — simplified utility permitting

Frequently Asked Questions
What was the main engineering challenge on the Afton Lake neighborhood project?
Fire marshal regulations capped the development at 30 residential units for a single access point, limiting the revenue potential of a residential-only layout on the site's high-visibility frontage.
How did JRH Engineering approach the Afton Lake site plan?
JRH added commercial reserve lots at the front of the property, a land use not subject to the residential unit cap, while keeping the 30-unit residential cap in the interior and routing storm and sanitary to existing TxDOT infrastructure.
What were the results of the Afton Lake project?
JRH added higher-value commercial frontage lots, accommodated the fire marshal's 30-unit residential cap within the design, and simplified utility permitting by routing storm and sanitary to existing TxDOT infrastructure.
