Marinilla betterment levy: two publicly documented phases

Two related public objects

The primary 2023 record documents consulting services to conduct the study, prepare the calculation and determination, and advise implementation of a second betterment-levy phase arising from changes in land classification and planning rules across different areas of Marinilla. It is the primary source for this page because it represents the more recent phase.

A 2022 SECOP II process records a related first phase: study, calculation, determination and implementation advice for a betterment levy associated with changes in land classification and planning regulations. GeoSAT's portfolio contains corresponding records for both phases.

What the evidence supports

The sources support the statement that two territorial-consulting scopes were published and that GeoSAT records them as related experience. They also show that the object was not limited to drawing a map: it combined study, calculation, determination and implementation support around planning decisions.

This page does not publish the properties reviewed, subject areas, calculation models, estimated or assessed values, administrative acts, charges or revenue. A procurement object does not by itself prove that every activity was accepted or produced a particular fiscal result. Those conclusions would require additional public deliverables, acceptance records and decisions.

Separation from the current POT framework

This is historical experience in territorial information and betterment levies. It does not demonstrate compliance with the current LADM_COL-POT model or Decree 381 of 2026, both of which postdate the two processes. A betterment-levy study is also not equivalent to full POT formulation or adoption. The instruments may use some of the same layers and land-classification decisions, but their powers, models and procedures are different.

Lesson for geospatial readiness

A similar process needs to preserve the origin and effective period of land classifications, treatments, regulations and analysis units. Geometries should link to the act or document that gives them context, and each change should retain traceability between scenario, calculation and the version used. If parcel or cadastral information is reused, its purpose and cutoff must be declared without confusing it with the planning model.

The Marinilla evidence demonstrates alignment with that problem. A new engagement must examine the current framework, authorized sources, institutional milestones and its own acceptance criteria. A GIS diagnostic can organize layers, metadata and open issues, but it cannot replace the competent legal, economic or administrative decision.
