City GreenPrint 1.0

The City has collaborated with the Green Infrastructure Center (GIC) to produce City GreenPrint 1.0, Charlottesville's Green Infrastructure Guide. This document supports the conservation and restoration of Charlottesville’s green infrastructure. It provides an introduction to what green infrastructure is and presents Charlottesville's green infrastructure baseline. GreenPrint also includes a summary of planning and analysis tools developed specifically around the topic of tree planting potential. Intended users include City staff and decision makers, developers, citizens, and anyone who wants to support the City’s goal to be A Green City.

City GreenPrint 1.0 contains:

A compilation of green infrastructure assets
Key facts and statistics about the city’s green infrastructure
Maps of key green resources and tips for how to use them
An analysis of tree-specific planting opportunities
Resources for implementation

The wealth of information presented in the numerous maps in City GreenPrint 1.0 can be viewed or downloaded below. There are two categories of maps:

City Asset Maps - present the city’s green infrastructure extent, location, and how it supports important goals such as clean water, livable neighborhoods, settings for cultural sites, recreation, and also social equity in terms of how assets are distributed citywide.
Potential Tree Planting Map Books- the result of high-level GIS analyses to identify where there are potential locations for new tree plantings throughout the city. The locations identified in these map books represent hypothetical planting locations that can serve as a strategic planning tool as Charlottesville continues to enhance its urban forest. The map books come in two formats:
- A citywide screening of where there may be potential to plant trees, which is a useful first step in understanding not only where and how many trees might be planted, but also what benefits might be associated with planting in a given location.
- A supplemental map series that provides an overview of potential tree planting locations at a neighborhood level. The supplemental map series was created to summarize five metrics that provide insight into potential benefits of tree planting - potential tree planting location density, relative temperature, household income, sub-catchment imperviousness, and population density.

Note: the maps are static maps that were developed in January 2017 based on the most current tree canopy data available at the time, which was generated from a 2014 aerial flyover of Charlottesville.

Note: Map files are large and may take a minute to load.

Map Name	Description
Tree Canopy	Depicts the extent of existing tree canopy coverage in Charlottesville
Charlottesville's Green Networks	Provides a snapshot of the city’s green resources that support both wildlife and people
Tree Canopy Patches	Shows a distribution of forest patches meeting certain size criteria
Impervious Surface Coverage by Subcatchment	Depicts the extent of impervious surface coverage of small drainage areas
Tree Canopy Coverage by Street	Depicts tree canopy coverage within 50 feet of roadways
Tree Canopy Coverage by Subcatchment	Depicts tree canopy coverage of small drainage areas
Tree Canopy Within 100 Feet of Surface Water	Depicts tree canopy coverage within riparian buffer areas
Recreation Assets	Shows where tree canopy exists relative to various recreational assets
Historic and Cultural Assets	Shows historic and cultural assets such as National Register sites, schools, and parks
Major Watersheds and Flood Zones	Depicts Charlottesville's major waterways, watersheds, flood zones, and locations of green stormwater infrastructure
Public Lands and Schools	Shows lands owned by the City of Charlottesville, Charlottesville School Board, County of Albemarle, and University of Virginia

Map Name	Description
Potential Tree Planting Analysis - Map Book	An analysis of potential tree planting locations across the entire City of Charlottesville
Potential Tree Planting Analysis - ROW Map Book	An analysis of potential tree planting locations specific to rights-of-way in the City of Charlottesville

Map Name	Description
Potential Tree Planting Analysis - Point Density	Shows potential tree planting location density. These maps serve as a visualization, highlighting where many potential tree planting locations are clustered together.
Potential Tree Planting Analysis - Point Density - ROW	Shows potential tree planting location density within city right-of-way. These maps serve as a visualization, highlighting where many potential tree planting locations are clustered together.
Potential Tree Planting Analysis - Relative Temperature	Shows where temperatures are highest and lowest at each potential tree planting location, which indicates where trees may provide maximum benefit for temperature reduction.
Potential Tree Planting Analysis - Relative Temperature - ROW	Shows where temperatures are highest and lowest at each potential tree planting location within city right-of-way, which indicates where trees may provide maximum benefit for temperature reduction.
Potential Tree Planting Analysis - Household Income	Shows the median household income, based on census block groups, at each potential tree planting location. The maps can help ensure that the many benefits provided by trees can be enjoyed by residents across the spectrum of incomes in the city.
Potential Tree Planting Analysis - Household Income - ROW	Shows the median household income, based on census block groups, at each potential tree planting location within city right-of-way. The maps can help ensure that the many benefits provided by trees can be enjoyed by residents across the spectrum of incomes in the city.
Potential Tree Planting Analysis - Subcatchment Imperviousness	Shows the impervious surface coverage of stormwater sub-catchments at each potential tree planting location. One of the major benefits provided by trees is reducing stormwater runoff.
Potential Tree Planting Analysis - Subcatchment Imperviousness - ROW	Shows the impervious surface coverage of stormwater sub-catchments at each potential tree planting location within city right-of-way. One of the major benefits provided by trees is reducing stormwater runoff.
Potential Tree Planting Analysis - Population Density	Shows the relative population density at each potential tree planting location. All else being equal, trees planted in densely populated areas will provide more benefits to those in close proximity.
Potential Tree Planting Analysis - Population Density - ROW	Shows the relative population density at each potential tree planting location within city right-of-way. All else being equal, trees planted in densely populated areas will provide more benefits to those in close proximity.
