CASE STUDY 32 — FM 149 Neighborhood Phase 1 140-Acre Private Road Neighborhood | Civil Engineering Design

PROJECT OVERVIEW

JRH Engineering provided complete civil engineering design for Phase 1 of a 140-acre private road neighborhood in Anderson, Texas. The project faced a limited budget, a road that required fire marshal approval for extended single-access length, and a need to fund construction before the full development was generating revenue. JRH solved the funding problem by subdividing and selling FM 149 frontage lots first, secured a fire marshal exception for the road length, and repurposed an existing cattle stock tank as the detention facility — eliminating new pond construction entirely.

AT A GLANCE

Site Civil Design

● Full civil design for private road neighborhood Phase 1 including road layout, grading, lot design, and drainage

● Private road designed to county standards — FM 149 frontage lots subdivided first to generate construction capital

● Existing cattle stock tank repurposed as detention facility — water surface lowered, outfall installed, new pond construction eliminated

● Fire marshal exception secured for single-access road length — maximum road served by one access point without triggering a second access requirement

Utility Infrastructure

● Individual wells and septic systems for each lot — no central utility infrastructure required

● Per-lot utility approach eliminated utility extension permitting from the project scope entirely

Stormwater & Drainage

● Existing cattle stock tank converted to detention — lowered water surface created stormwater storage volume without building a new pond

● Outfall installed from converted tank to receiving drainage — straightforward connection using existing on-site infrastructure

● Open ditch road drainage along private road — no underground storm sewer required

Permitting & Agency Coordination

● Anderson County and TxDOT approvals pursued concurrently

● Fire marshal exception negotiated and documented — maximum single-access road length approved

● FM 149 frontage lot subdivision coordinated with county plat approval to generate construction capital before Phase 1 road construction

THE CHALLENGE

A 140-acre rural neighborhood development on a limited budget needs a construction funding strategy, not just an engineering strategy. Road construction costs money before lot sales generate revenue — and if the road is too long for a single access point without a fire marshal exception, that is another approval process that can delay the project. The existing cattle stock tank was an asset sitting unused.

JRH's Approach

JRH addressed the funding challenge first: by subdividing and selling the eight FM 149 frontage lots before major construction began, the developer generated capital that funded the road and infrastructure. The fire marshal exception for extended road length was negotiated and documented early — removing that uncertainty from the schedule. The cattle stock tank was converted to the detention facility by lowering the water surface and installing an outfall, eliminating new pond construction cost entirely.

The Result

Phase 1 of a 140-acre neighborhood — funded through frontage lot sales, permitted with a fire marshal exception, and drained through a repurposed stock tank rather than a new detention facility.

RESULTS

● Construction capital generated through FM 149 frontage lot subdivision before major construction began

● New detention pond construction eliminated — existing cattle stock tank converted to compliant detention facility

● Fire marshal exception secured for extended single-access road length
