Land Cover Analysis: Urban Tree Canopy Assessments Results of the UTC Assessment will
The purpose of the Urban Tree Canopy Assessment projects are to use aerial photographs and satellite imagery with geographic information systems (GIS) data to understand the existing urban tree canopy (UTC) and help stakeholders make informed decisions about their urban forest.
assist in Managing and Growing the Urban Forest.

Case Study: Bonney Lake, Washington (2011) • • •
Project Area: ~11 square miles Goal: Augment Stormwater Management Areas (SMAs) Solution: o
Map the location and extent of tree canopy
o
Overlay SMAs
o
Identify relationship between canopy cover and storm surge on storage/treatment facilities
o
Develop a strategic planting plan to increase tree canopy where storm surge is challenging SMA capacity
Case Study: Bonney Lake, Washington (2011) •
Project Area: ~11 square miles
•
Goal: Protection of Significant Canopy
•
Solution: o
Map the location and extent of tree canopy
o
Overlay canopy with development potential
o
Determined how the canopy loss on highpotential parcels will affect overall canopy cover and community goals
o
Develop a planting strategy to mitigate the loss of tree canopy to development
Case Study: Roseville, California (2008) •
Project Area: ~35.5 square miles
•
Goal: Street and Park Tree Management
•
Solution: o
Collect a GIS inventory of public trees on streets, in parks, and at city facilities
o
Integrate inventory into TreeKeeper® management software
o
Manage trees and update inventory data (Generate work orders, track inspection and history, attach photos and reports, etc. )
Case Study: Roseville, California (2012) •
Project Area: ~35.5 square miles
•
Goal: Natural Resource Preservation
•
Solution: o
Map and identify fragmentation of oak woodlands and other tree canopy
o
Identify priority planting sites for the protection of soils and natural resources
o
Develop planting sites to increase connectivity of existing canopy, wildlife habitat, and trail system. *Supports General Plan and community design goals.
