Creating balanced and meaningful zones is a common challenge across many planning and analytical workflows. For example, emergency response teams may need to define service areas based on the locations of existing fire stations, while urban planners may divide a city into planning zones based on population, risk, or social vulnerability. In these scenarios, zone design directly affects how resources are prioritized, allocated, and communicated.<\/p>\n

The Build Balanced Zones (BBZ) tool in ArcGIS Pro is designed to support these decisions by intelligently grouping spatial features into contiguous zones that balance multiple criteria. In this blog, we walk through two practical, real\u2011world workflows that demonstrate how Build Balanced Zones can be applied in real-world scenarios. Along the way, we highlight several key enhancements introduced in ArcGIS Pro 3.7, showing how they improve both analytical flexibility and result accuracy.<\/p>\n

Workflow 1: Balancing Risk and Equity \u2014 Creating Resilience Planning Zones with National Risk Index Data<\/h2>\n

Planning and policymaking analysis often begin with polygon data such as census tracts, neighborhoods, or administrative units. However, existing boundaries may vary significantly in population, risk exposure, or vulnerability, making them difficult to use directly for equitable planning or comparison.<\/p>\n

In this workflow, we use the National Risk Index (NRI) dataset to create 10 balanced resilience planning zones for the city of Philadelphia. The NRI dataset is developed by FEMA.

Workflow2: Balancing Workload and Accessibility \u2014 Creating Maintenance Zones around Fixed Workstations<\/h2>\n

Generating zones and distributing workloads around existing facilities is a common use case in real-world settings. In ArcGIS Pro 3.7, we introduced the Custom seed locations feature to help build zones that are more reasonable in real-world settings.<\/p>\n

Beyond These Workflows: Additional Parameters to Explore<\/h2>\n

Beyond the parameters used in the workflows above, Build Balanced Zones provides a range of additional options that support more specialized analytical needs. These parameters are not required for every use case, but they allow analysts to adapt the tool to different real\u2011world constraints without complicating simpler workflows.<\/p>\n

For example, the Get spatial weights from file option enables you to define spatial adjacency explicitly using a spatial weights matrix, rather than relying on geometry-based contiguity.<\/p>\n

Distance to Consider parameter can be used to favor zones that are closer to specific facilities or points of interest, such as hospitals, service centers, or depots. This is useful when proximity or response time is an important consideration.<\/p>\n

Categorical variables can be included to maintain proportions of categorical attributes\u2014such as land\u2011use type\u2014across or within zones. This helps preserve important categorical patterns while still balancing numeric criteria.<\/p>\n

Advanced parameters expose additional controls over the genetic algorithm, including population size and mutation behavior. While the default settings work well for most workflows, these options can be useful when fine\u2011tuning performance or experimenting with alternative solutions.<\/p>\n

Together, these parameters make Build Balanced Zones flexible enough to support a wide variety of planning and operational scenarios, while allowing analysts to keep individual workflows as simple or as advanced as needed.<\/p>\n

Closing Thoughts<\/h2>\n

In this blog post, we introduced two workflows using Build Balanced Zones to develop resilience planning zones and create a maintenance plan. These workflows illustrate how Build Balanced Zones supports practical use cases using real\u2011world data. We also highlighted the enhancements to the tool in ArcGIS Pro 3.7 along the way. Whether starting from polygons or points, BBZ provides a flexible framework for creating zones that balance multiple criteria while remaining spatially meaningful. With this tool, analysts can build zones with greater confidence, clarity, and efficiency across a wide range of applications.<\/p>\n"}],"related_articles":"","show_article_image":true,"card_image":false,"wide_image":false},"yoast_head":"\nNew in ArcGIS Pro 3.7!
