$1 million for trees and energy efficiency in Phila.

Over the next four years, the Home Depot Foundation will spend $1 million to plant street trees and retrofit houses in parts of North Philadelphia with more energy-efficient water heaters and windows.

The program will be coordinated by the city, Pennsylvania Horticultural Society and Asociación Puertorriqueños en Marcha.

The first tree will be planted at Eighth and Berks Streets at 3 p.m. tomorrow, when Mayor Nutter is to announce the grant.

Plans call for new trees along Berks and Norris Streets, Germantown Avenue and around neighborhood schools. Besides water heaters and windows, the retrofits may also include rain barrels, landscaping and white roofs, which deflect rather than absorb heat.
