Placer County Sees Planning Decision Impacts in Real Time
As reported in ArcUser, Fall 2017
In 2016, Placer County had the second-highest increase in population among California’s 58 counties, according to the California Department of Finance. The county’s diverse economic base includes a mix of manufacturing, high-technology, retail, and business services companies. This has supported the strong population growth the county has experienced for more than a decade. For the period between 2003 and 2013, it was the fastest-growing county in the Sacramento region with a population growth of 26 percent.
Placer County routinely performs financial analysis for future development. This analysis of revenues and expenditures evaluates the financial impacts of land use within developments or specific plans. County officials evaluate potential revenues, such as property or sales taxes, provided by a development. That figure is balanced with county expenditures resulting from the development for public safety, general government, roads, and other costs.
County acquires GeoPlanner ...
Placer County acquired GeoPlanner for ArcGIS to assist it in performing financial impact analysis. GeoPlanner for ArcGIS empowers users to plan, test, and evaluate city, regional, and landscape-scale scenarios in a collaborative, iterative environment. A web-based planning tool, GeoPlanner lets Placer County apply geodesign principles and uses data on intact areas from the National Intact Habitat Cores database provided by Esri to identify green infrastructure and preserve it. GeoPlanner can provide a more complete understanding of how an area performs or behaves.
Once a project is created in GeoPlanner, other users in the organization are invited to collaborate and become part of the project team. As team members, they can access and work with project scenarios by sketching and drawing using symbols and drawing tools.
Dashboards display key performance indicators ...
GeoPlanner dashboards display qualitative and quantitative information about the scenario under consideration through information on key performance indicators (KPIs) displayed in easyto-read gauges and charts that provide immediate feedback on design decisions by visualizing their impacts in real time. The impacts of multiple KPIs can be tracked at the same time the advantages and disadvantages of scenarios can be evaluated to aid in balancing multiple competing priorities.
Using GeoPlanner, Placer County can run spatial analysis on the fly, compare scenarios, and produce data-informed plans using the real-time dashboards and KPIs. This helps county government staff and stakeholders understand the quality, performance, and impact of plans as they are designed.
Placer County uses KPIs to model the financial impacts of different land-use scenarios. Using the KPI Report, the county explores many scenarios by measuring their effects on KPI values. In its comparisons, Placer County uses metrics that include estimates for residential units, population, jobs, areas of different land use, areas of commercial developments, revenues, and expenditures.
Non-GIS professionals ...
Non-GIS professionals at Placer County use GeoPlanner to draw and paint different land-use scenarios. As planners and analysts change land-use patterns—such as from low- to high-density residential—KPIs immediately reflect changes in revenue and expenditure estimates. Placer County’s GIS group uses GeoPlanner to develop the layer of base land use and build out the KPIs.
“Using GeoPlanner, we see and understand in real time the financial impacts of land use change on a project,” said Kelly Berger, Placer County GIS coordinator. “As land use changes in the plans, GeoPlanner helps us explore the greatest cost benefit to the county and its citizens,” Berger said.
As Placer County continues to grow, decision-makers can further analyze and understand the financial impacts of development. Through the iterative process of developing a land-use plan, GeoPlanner helps Placer County contain costs each time the analysis needs to be performed.
GeoPlanner saves time and money ...
“GeoPlanner saves considerable time and money by empowering us to perform the analysis in-house prior to finalizing it through consultants,” Berger said. “We can see in real time the impacts of decisions, maximize land use, and minimize costs to develop a strong land-use plan that will benefit the citizens, the developers, and the county.”
