After a lengthy public hearing and debate, the San Luis City Council adopted new subdivision regulations and related zoning amendments meant to incorporate state House Bill 2447 and speed plat approvals by giving administrative staff and the city engineer authority over preliminary and final plats.

Juan Tejeda of planning and zoning described the changes as an update to standards that in many cases dated to previous county standards: "This is the adoption process of the subdivision regulations... they incorporate the new House Bill 2447 that requires city staff to review and approve preliminary final plans," he said. Staff and the city attorney told council the regulations add a formal modification process so the city engineer can approve deviations from standards, such as requests about half-width (phased) street construction, rather than automatically sending those items to council.

Developers and engineers who addressed council urged the city to retain the ability to construct half-width roads during phased developments, citing precedents in nearby jurisdictions and the practical needs of developers and nonprofit builders. Vianey Vega of Vega & Vega Engineering asked the council to "consider that and see if it's possible to keep that section, as it was before," explaining the half-width approach allows phased work while preserving circulation. Developers warned that requiring additional modification steps could delay projects and add financing costs.

Staff and several council members countered that half-width streets have in some cases remained incomplete for many years and create safety, operational and alignment problems; staff and the city engineer said the modification process and subdivision assurances (bonds) are tools to protect the public interest. One council member cited a long unresolved example (10th Avenue) where incomplete street work led to a decades-long problem.

After extended debate, council approved Resolution 2387 and later voted to adopt Ordinance 473 (subdivision regulations) and Ordinance 474 (zoning text changes), with a small number of abstentions recorded in the roll calls. Council directed staff to publish the rules and to establish clear timelines and procedures for modification requests and responses.

The adoption changes the administrative pathway for subdivision approvals and creates a formal mechanism for applicants to request modifications from the city engineer; appeals of engineering decisions may still come to council if applicants pursue them.
