ENVISION TOMORROWUPDATES AND INDICATORS

What is Envision Tomorrow?

Suite of planning tools: GIS Analysis Tools Prototype Builder

Return on Investment (ROI) model

Scenario Builder Extension for ArcGIS

Performance Models

Why Use Scenario Planning?

Weigh choices against consequences

Test policy options quickly Prepare for uncertainty Develop strategies to

optimize outcomes

Scenario Building Process

Create Building & Development

Types

Scenario Development

EvaluationBaseline Analysis

Regional “Balance” Analysis

Jobs-Housing balance impacts transportation

GIS tool to identify imbalanced areas Candidates for

detailed scenarios

Redevelopment Readiness Analysis A tool to assess which parcels within a study area

may be candidates for redevelopment in the short term.

Two methods: Low Hanging Fruit: isolate the bottom quartile of total

value per acre (land + improvement) Timing: estimate the parcels that are ready today, or

within 5-10 years based on the age of the structure and the value of the land and a depreciation schedule.

Fiscal Impact Modeling

A Modified Version of the Federal “FIT” Fiscal Impact Model

Estimate and compare county and municipal revenues and costs from scenarios

Uses building values and infrastructure costs from Envision Tomorrow to capture explicit differences in revenues and costs from different land use types

Indicators: Revenue Cost Ratio New Revenues (Property, Income and

Sales Taxes) New Costs (Infrastructure, O&M and

Services)

Revenues vs. Expenditures

Net Annual Revenue

Proximity Measures (Walkable Access)

Calculate the proportion of development in a scenario that is within walking distance to any amenity, such as a school or park

Example: 50% of residents are

within a 10 minute walk to a park

AffordabilityHousing + Transportation + Energy Costs

Assess trade-offs Trade higher housing costs for lower

transportation costs?

Shared Parking Opportunity

Increases in walking combined with mixing uses presents an opportunity for shared parking
