Livingston Parish adopts unified development code after yearslong effort on growth and flooding

The Livingston Parish Council adopted a Unified Development Code on July 23, creating a single development rulebook for Livingston Parish after a yearslong effort to bring development standards under one framework.

The code covers where development may occur, how property can be divided into lots, drainage and flood-related requirements, and the procedures used to approve projects. That means developers and property owners will have a parishwide set of rules to consult for construction and subdivision proposals.

What the code covers

The Unified Development Code addresses land-use decisions as well as the practical requirements tied to new development. Its subjects include permitted land uses, lot splits, drainage, flood handling and project-approval procedures.

For residents, homeowners, farmers, local businesses and others considering construction or a subdivision, those topics can affect how a project is evaluated. The code also has implications for drainage and flood-control requirements connected to development decisions.

The town of Livingston, the parish seat, lies within the code’s jurisdiction. The measure is described as applying throughout Livingston Parish, including Livingston, Louisiana. The available information does not establish that every parish municipality applies identical rules beyond the code’s stated parish jurisdiction.

Adoption followed years of work

The council’s official agenda center lists its July 23, 2026 meeting at 20355 Government Boulevard in Livingston. A local report about that meeting identified the council’s action as adoption of the Unified Development Code.

The action followed a yearslong effort to create unified development rules for the parish. The change is a final council adoption of the code, not a proposal or a building moratorium. It does not, by itself, establish that flooding will immediately stop or that existing drainage problems have been resolved.

Effective date remains unclear

The available source material does not include the adopted code text. It also does not identify an effective date, a section-by-section implementation plan or a schedule for putting the new procedures into practice.

That information will be important for anyone preparing a construction or subdivision project, because the adoption date and the date the rules take effect may not be the same. The approved material identifies no further deadline or next council step.
