Challenge

Build Urban Site Selection and Zoning Compliance Agent using LlamaIndex

Selecting optimal sites for urban regeneration projects—such as King's Cross—requires synthesizing transit accessibility, historic land use, and local zoning parameters. Developers will build a site selection agent using LlamaIndex. The agent indexes municipal urban plans, transit density maps, and environmental hazard filings. It scores candidate sites based on redevelopment feasibility, transit proximity, and zoning compliance, automating initial feasibility studies for master plan developers.

Challenge brief

What you are building

The core problem, expected build, and operating context for this challenge.

Develop an urban site selection agent using LlamaIndex to score development feasibility across spatial and regulatory datasets.

Delivery guide

How work is evaluated

Evaluation

Evaluates site feasibility scoring accuracy and retrieval precision across zoning documents.

Datasets

Challenge datasets

Public datasets, plus the private datasets you have access to.

Evaluation rubric

How submissions are scored

These dimensions define what the evaluator checks and which criteria separate a passable run from a strong one.

Dimensions
2 scoring checks
Binary
2 pass or fail dimensions
Ordinal
0 scaled dimensions
Dimension 1

Zoning Compliance Check

Verifies that proposed FAR <= allowed FAR yields zoning_compliant = True

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Dimension 2

Feasibility Score Precision

Fidelity of feasibility calculation • target: 0.95 • range: 0-1

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Learning goals

What you should walk away with

  • Index municipal zoning codes and spatial transit datasets into LlamaIndex vector stores

  • Build custom retrieval tools for filtering parcels by zoning allowance and FAR (Floor Area Ratio)

  • Calculate composite Feasibility Scores for candidate urban development sites

  • Generate automated site selection executive summaries
