Louisiana New Urbanism: River Ranch & Rouzan

How to read this #

This is a study guide, not a brochure. It exists to answer one question: how do you plan and build a walkable traditional town in late-20th-century Louisiana, where the zoning code assumes you are building a car-dependent subdivision? River Ranch in Lafayette and Rouzan in Baton Rouge are the two best-known answers. River Ranch is the work of Lafayette architect-planner Steve Oubre (Architects Southwest); Rouzan was master-planned by a different firm, LRK, on the same model. They are paired here because both are Louisiana TNDs, not because one designer made them.

Read it in order if the ideas are new to you. Chapter 01 sets up the vocabulary of New Urbanism and the Traditional Neighborhood Development (TND) so the two case studies make sense. Chapter 02 introduces the designer. Chapters 03 and 04 are the deep dives. Chapter 05 puts them side by side. Chapter 06 is the bibliography, with live links to every regulating document and primary source we could verify. Chapter 07 is honest about what we could not confirm.

New Urbanism & the Traditional Neighborhood Development #

New Urbanism is a planning and design movement that emerged in the United States in the 1980s as a reaction against post-war suburban sprawl. Its institutional home is the Congress for the New Urbanism (CNU), founded in 1993, and its founding theorists are the husband-and-wife team Andrés Duany and Elizabeth Plater-Zyberk (DPZ), whose Florida town of Seaside is the movement's first built icon. The argument is simple to state and hard to execute: the walkable, mixed-use neighborhood that humans built for thousands of years before the automobile is a better place to live than the single-use subdivision, and we can build it again on purpose.

The TND, defined #

A Traditional Neighborhood Development (TND) is the project-scale expression of New Urbanism: a master-planned neighborhood, usually built on greenfield land, that reproduces the structure of a historic small town. River Ranch and Rouzan are both TNDs. The defining features, drawn from the CNU Charter, are:

• A walkable core and an edge. The neighborhood has a discernible center (a square, a main street, a civic building) and a recognizable boundary, sized so that most daily needs are within a five-minute (quarter-mile) walk of the center. Planners call this the pedestrian shed.
• Mixed use. Shops, offices, civic buildings, and several types of housing sit within the same neighborhood, often within the same block or even the same building (live-work units). This is the single biggest break from conventional zoning, which legally separates these uses.
• Mixed housing. A range of types and prices, from apartments over shops to townhouses to detached houses, so a range of ages and incomes can live in one place. (How well TNDs actually deliver income mix is contested; see the critiques in each case study.)
• A connected street network. A grid or modified grid of narrow, slow, tree-lined streets with many connections, rather than the loops-and-cul-de-sacs hierarchy that funnels everything onto a few arterials. Connectivity is also social: Oubre is explicit that TNDs should connect to their neighbors, not wall them off.
• Quality architecture and public space. Buildings frame the street with porches and short setbacks; parking and garages are pushed to rear alleys; the public realm (squares, greens, sidewalks) is treated as the most important room in the town.

The Transect: the organizing idea #

The intellectual backbone of the movement's codes is the rural-to-urban Transect, a DPZ concept that classifies the human environment into six zones along a gradient, from most rural to most urban:

A TND is essentially a deliberate slice of the Transect: a T5 town center surrounded by T4 and T3 fabric, with parks reaching down toward T2/T1. Every element of a building, the setback, the porch depth, the window proportion, the street width, is calibrated to its Transect zone. This is what lets a form-based code regulate "fit" without dictating taste.

Form-based codes vs. conventional zoning #

This is the mechanism that makes TNDs legal, and the reason they are hard to build. Understanding it is the key to understanding Oubre's "119 code waivers" at River Ranch.

Two documents do the work in a TND:

• The regulating plan — the master map that assigns every lot its building type, setback line, and frontage. It is the legal heart of the project.
• The pattern book / architectural standards — an illustrated guide to the permitted building types, materials, porch and window proportions, and regional styles. It is how a developer enforces a coherent look without a single architect drawing every house.

The DPZ SmartCode is the best-known open-source model FBC. After Hurricane Katrina, Louisiana produced its own statewide version of the idea, the Louisiana Speaks Pattern Book (Urban Design Associates), which codified the regional vernacular that River Ranch had already been building.

The Louisiana / Acadian vernacular #

Form-based codes regulate how buildings sit; the pattern book supplies what they look like. In south Louisiana that means a specific set of pre-air-conditioning, pre-automobile building types adapted to heat, humidity, and flooding:

• The gallery / deep front porch — shade and social space; the porch is the room that faces the street and makes the sidewalk feel safe.
• The raised Creole cottage and the shotgun — narrow, raised off the ground for flood and air, pushed to the front of a deep lot.
• The rear alley with garage and outbuilding (the "garçonnière") — cars and service to the back, so the street is for people.
• A small palette of regional styles — Acadian, Creole, French Colonial, Caribbean, American Colonial, Neoclassical, applied within tight rules so the variety reads as an old town that grew over time rather than a theme park.

Ten characteristics of a good neighborhood #

The University of Notre Dame's 2013 graduate urban-design studio, Visions for Lafayette, distilled good urbanism into ten plain characteristics. It is the most useful checklist in this guide: read River Ranch and Rouzan against the list and each town's strengths and gaps come into focus.

Steve Oubre & Architects Southwest #

Steve J. Oubre, AIA, LEED AP is the architect-planner behind River Ranch and the through-line of this guide. (His later work at Rouzan in Baton Rouge was limited to a library consult; that project’s master planner was LRK — see Chapter 04.) He was born and raised in Loreauville, in Iberia Parish, deep in Cajun country, a detail he cites as the root of his regional design sensibility. He earned a Bachelor of Architecture from the University of Louisiana at Lafayette (then USL) in 1976, and in 1980 co-founded Architects Southwest (ASW) in Lafayette. (UL Lafayette, 2014; Americana dev team bio.)

From cultural architecture to town-making #

Oubre's path into New Urbanism ran through historic preservation. He designed Vermilionville, the replica Acadian village and living-history park in Lafayette, work he credits with teaching him "to love historic buildings." That study of pre-automobile Louisiana settlement patterns became the raw material for his TND work. His first New Urbanist project, Ile de Canne (1993), was done "in association with Andrés Duany and Elizabeth Plater-Zyberk", a direct line to the movement's founders, a collaboration that recurred in the post-Katrina recovery charrettes. (Hennessy Chronicles, 2006.)

Design philosophy, in his words #

• On the five-minute walk: the appeal of TNDs is "mixed use of buildings [that] allow people to live and work within a five minute walking distance," with different economic segments coexisting. (Hennessy, 2006.)
• On connectivity, not gating: "We're very much not about gating communities, rather we want to connect adjacent neighborhoods." (The Advocate, "Louisiana Inspired".)
• On built proof: on how River Ranch unlocked approvals for later projects, "We have taken all of the review people to River Ranch. That has been the deciding factor." (CNU Public Square.)
• On the charrette: he is a committed practitioner of the multi-week community design charrette, a method he says crystallized during the post-Katrina recovery work.

Beyond the two case studies: the portfolio #

River Ranch and Rouzan are the famous two, but ASW/Oubre planned a remarkable number of Louisiana TNDs, by one 2006 count, 22 in various stages. The portfolio is the context that makes them more than one-offs:

He also did significant post-Katrina/Rita recovery work: he was the only Louisiana architect on the Louisiana Recovery Authority planning team, working alongside Peter Calthorpe, Urban Design Associates, and Duany, and was lead designer of the panelized, flood-resistant Katrina Cottage II (a sub-$60K, ~470 sq ft prototype built in three weeks). (CNU Public Square.)

Firm succession: Oubre stepped back from day-to-day leadership around 2016 but kept consulting. ASW merged with Abell + Crozier in 2020 to form ACSW, which merged with Rozas Ward in 2024 to form AQ Studios (Lafayette / New Orleans / Lake Charles). (AQ Studios.)

River Ranch, Lafayette #

River Ranch is the most successful and most copied TND in Louisiana, a roughly 320-acre former soybean field on Lafayette's south side, between Kaliste Saloom Road, Camellia Boulevard, and the Vermilion River. It is the project that proved, to bankers, regulators, and the dozens of developers who toured it, that a walkable traditional town could be built and sell in Louisiana. (CNU Public Square, 2002.)

History & developers #

• Conceived mid-1990s by attorney Robert Daigle (1951–2024) and accountant Rodney Savoy, on former farmland. Oubre began planning it around 1994. (The Advocate, Daigle obituary.)
• Groundbreaking ~1997. Early phases filled quickly: by late 2002 about 145 families were already in residence, with roughly 50 more homes under construction and 145 apartments nearing completion (CNU, Dec 2002). The Camellia Boulevard bridge opened in September 2003, improving access for the later phases and the Town Center. (A 2018 retrospective dates the “first homeowner” to ~2004; that conflicts with the contemporaneous 2002 count, which this guide follows.)
• Build-out target: ~1,200 units (a mix of houses, townhomes, apartments, and live-work units). By the 2010s the development held an estimated 3,300+ residents and 2,100+ daytime workers, with 2,000+ daily visitors.
• The developers later founded Southern Lifestyle Development (SLD) (2012) to carry the model across the Gulf South (Sugar Mill Pond, and projects in Mississippi, Alabama, Florida).

The master plan #

River Ranch is organized as two districts, each with its own park, shopping district, and trail system, knit together by a connected street network and anchored by a Town Center.

• The Town Square / Town Center is the T5 heart: a signature gazebo-and-lawn square that hosts the "Rhythms on the River" concert series and the "Big Easel" art festival, ringed by a grocery, restaurants, retail, offices, real-estate firms, a four-diamond boutique hotel (the Carriage House), and a private City Club (fitness/pool/tennis).
• Walkability features: extra-wide sidewalks, traffic calming, a dedicated bike path, hiking trails, underground pedestrian walkways, and pockets of pedestrian-only street. Big-box anchors (Costco, Whole Foods, Rouses) sit within or adjacent to the expanded development.
• Housing range: apartments through ~4,000 sq ft estate homes, the mixed-housing principle in physical form, though at a price point (roughly $475K to $1.4M+) that places it firmly in the upper-middle/luxury tier.

Architecture & the code #

River Ranch deploys roughly seven regional styles, Caribbean, French, American Colonial, Creole, Acadian, Spanish, and Neoclassical Revival, governed by custom building codes ASW wrote specifically for the project. The codes regulate windows, shutters, doors, walls, and building placement so the variety reads as an organically grown town rather than a pastiche. Front porches, short setbacks, and active street edges are explicit priorities. (Wikipedia; AQ Studios portfolio.)

Lafayette Consolidated Government later folded TND-friendly mechanisms into its Unified Development Code (Chapter 89), including a Mixed-Use Neighborhood (MN) district and a Planned Development (PD) district, the closest current regulatory analogs to what River Ranch needed assembled by hand.

Reception, awards & critique #

• Awards: 2000 American Planning Association President's Award (most outstanding planned project in Louisiana) and an AIA award for the master plan. The Town Center was named one of "14 Great Town Centers and Urban Villages" by the Urban Land Institute and featured in ULI's 2008 book Creating Great Town Centers and Urban Villages.
• Influence: 100+ developers toured it; it directly seeded Sugar Mill Pond, Provenance, and the broader "wave of TND in Louisiana." (CNU.)
• Critique, affordability: with no documented affordable/workforce-housing component and a $475K–$1.4M price band, River Ranch realizes the form of mixed housing more than the economics of it, a standard critique of New Urbanism nationally.
• Critique, infrastructure cost: 64 existing homes were demolished for the Camellia Boulevard construction that made the project accessible, an underreported cost borne by others.

Rouzan, Baton Rouge #

Rouzan is Baton Rouge’s most prominent Traditional Neighborhood Development: a roughly 117–120-acre infill project on the old “Ford farm” in the historic Southdowns neighborhood, at Perkins Road and Glasgow Avenue, about ten minutes from LSU and downtown. It applies the same TND model as River Ranch — walkable grid, village center, front porches, rear alleys — on a tighter urban infill site, and its road to getting built was a longer and more contested one.

History & the entitlement fight #

• Name: the land traces to J.P.M. Rouzan, a 19th-century Baton Rouge planter and slave owner whose Longwood Plantation appears in the 1860 slave schedule. (slaverybr.org.)
• Developer: Joseph T. “Tommy” Spinosa, through 2590 Associates, LLC (JTS Interests), also the developer of Perkins Rowe. He acquired the site around 2005.
• Rezoning (case TND-1-07): after contentious 2007 hearings, the EBR Metro Council adopted Ordinance 14280 on January 23, 2008, rezoning ~119 acres from single-family (A-1) to TND/PUD, with an approved program of 750 residential units + 100,000 sq ft of commercial. (225 Magazine.)
• Re-rezoning (2014): litigation forced the parish to amend the TND ordinance and re-rezone the site via Ordinance 15691 on an 11–0 vote, so the ~40 existing homeowners could secure financing and insurance. (WAFB.)
• Collapse & relaunch: Spinosa’s wider empire imploded (a $201.9M Perkins Rowe foreclosure judgment in 2012), and his sole Rouzan financier, First NBC Bank, was closed by regulators in April 2017, freezing the project. In January 2018 a group led by John Engquist (CEO of H&E Equipment) and attorney Charles Landry bought it — about $21M for 65 residential acres — and restarted construction. (NOLA.com.)

The master plan & what got built #

• Program: the 2008 ordinance capped the project at 750 homes and 100,000 sq ft of commercial (above); master-plan and marketing materials describe a build-out target nearer ~800 homes and ~120,000 sq ft of retail/office/dining, plus a Montessori-style early-childhood school, an EBR south-branch library, and 23 acres of open space, over a 10+-year build-out.
• Town center, plan A → plan B: the commercial core was first designed around a 33,000 sq ft Alamo Drafthouse Cinema plus apartments (KTGY). The Alamo deal fell through in 2016 when street-plan delays blew its timetable, and the center pivoted to grocery + multifamily. (NOLA.com.)
• Anchors as built: Sprouts Farmers Market (Louisiana’s first, opened June 26, 2019) and The Everly at Rouzan, a 277–280-unit, ~$58M apartment building with ground-floor retail (LRK), completed March 2024. The Trader Joe’s on Perkins Road is a separate, unrelated store.
• Amenities: a clubhouse, lap pool, and the Silo Farm — a half-acre community farm built around preserved concrete silos, designed by Daron Joffe (“Farmer D”), who also did the farm at Serenbe. (theclubhouseatrouzan.com.)

Architecture & regulating documents #

Rouzan’s building types run from ~1,550–2,250 sq ft cottages (many with French-Creole plan names) through custom single-family, townhomes, and the Everly’s multifamily. The TND design controls are strong: mandatory front porches on street-facing homes, rear-alley garages, mandated architectural variety across builders, and a non-gated edge that connects into Southdowns. (livinginbatonrouge.com.)

Where River Ranch was built on 119 hand-won waivers, Rouzan runs on a parish ordinance: the EBR Unified Development Code, Title 7, Chapter 8, §§8.217–8.218 (the TND district). The de facto regulating plan is the city’s TND-1-07 Final Development Plan; the architectural and use controls live in the recorded CC&Rs / Master Declaration. There is no separately published “Rouzan pattern book.”

Reception & the servitude lawsuit #

Rouzan is marketed and widely reviewed as Baton Rouge’s most walkable upscale neighborhood, praised for its location, design quality, on-site grocery and dining, and the Silo Farm. Criticism centers on price (small lots at a premium, ~$191/month HOA) and on density and drainage concerns raised by the Southside Civic Association since 2008. Unlike River Ranch, Rouzan carries no CNU award; its New Urbanist lineage runs through LRK.

River Ranch vs. Rouzan #

The two projects share a vernacular and a model — though not the same designer — and they are a study in how much execution and context matter. River Ranch went up on a clean greenfield with a developer who controlled the land and ground out 119 waivers one at a time; Rouzan was an infill site wedged among established neighborhoods, dependent on a parish-wide ordinance and entangled in opposition and finance.

The lesson the Louisiana TND movement took from the pair is the one Oubre states directly: built proof plus an ordinance up front beats heroics. River Ranch proved the product; the projects that followed it tried to get the parish to adopt a TND ordinance before breaking ground, so they would not have to re-fight the regulatory battle. Rouzan shows that even with the ordinance, an infill TND still has to win over the neighbors it connects to.
