CASE STUDY 18 — Dairy Queen HWY 6, Manvel, TX | Restaurant Site Civil Engineering

PROJECT OVERVIEW

JRH Engineering provided complete civil engineering design for a Dairy Queen restaurant on HWY 6 in Manvel, Texas. The small lot had no direct highway access — a condition that typically requires a costly and time-consuming TxDOT driveway permit battle. JRH secured a shared driveway with the adjacent gas station, resolved the access problem in one negotiation, and converted an unusable triangular corner of the lot into a retaining wall detention pond — turning dead space into a permitting asset.

AT A GLANCE

Site Civil Design

● Full site civil design including building pad, parking layout, drive-through configuration, and shared access design

● Shared driveway negotiated and designed with adjacent gas station — resolving the no-access condition without a standalone TxDOT driveway permit

● Unusable triangular corner of the lot converted into a retaining wall detention pond — dead space turned into a drainage asset while preserving maximum square footage for the restaurant and parking

● Building and parking layout optimized around the shared access point and corner pond

Utility Infrastructure

● Water and sanitary connected to City of Manvel and TxDOT infrastructure

● Dual-agency utility coordination completed concurrently with site plan review

Stormwater & Drainage

● Retaining wall detention pond placed in the triangular corner — land that had no viable building or parking use

● Corner pond configuration preserved the rectangular core of the site for the restaurant building and parking field

● City of Manvel and TxDOT drainage approvals pursued simultaneously

Permitting & Agency Coordination

● Shared driveway agreement with adjacent gas station negotiated before TxDOT submittal — access issue resolved proactively

● City of Manvel and TxDOT approvals pursued concurrently

● Triangular corner pond converted what would have been a site plan problem into a drainage solution — no awkward geometry in the buildable area

THE CHALLENGE
A small lot with no direct highway access and an awkward triangular corner is a difficult development puzzle. The no-access condition on a TxDOT highway typically means either a lengthy standalone driveway permit process or shared access negotiation with a neighbor who may not be motivated to cooperate. The triangular corner was essentially unusable for building or parking — but it still consumed land area that contributed to the site's drainage obligation.

JRH's Approach
JRH negotiated the shared driveway with the adjacent gas station — a neighbor who already had established access and had reason to support a coordinated approach. One negotiation resolved the access problem without a TxDOT permit battle. The triangular corner was then incorporated into the detention design as a retaining wall pond — converting the site's worst geometry into its drainage solution and keeping the rectangular core of the lot clear for the restaurant building and parking.

The Result
A fully permitted Dairy Queen restaurant on a constrained lot — with access established through neighbor negotiation and dead-space geometry converted into detention infrastructure.

RESULTS

● Highway access established through shared driveway with adjacent gas station — no standalone TxDOT driveway permit required

● Triangular corner converted to retaining wall detention pond — unusable geometry turned into a drainage asset

● Maximum restaurant and parking footprint preserved by containing detention in the corner dead space
