Environmental Preservation - As introduced, creates a grant program to facilitate green spaces in urban areas; authorizes the technical secretary of the air pollution control board to establish a program to encourage community-led programs that reduce air pollution. - Amends TCA Title 4, Chapter 3, Part 5; Title 5; Title 6; Title 7; Title 11; Title 43, Chapter 24 and Title 68, Chapter 201.

HB 950, if enacted, would create an Urban Green Space Development Fund to provide state grants for purchasing or protecting green spaces (like parks, community gardens, and natural areas) in urban areas defined by U.S. Census data. Local governments and private nonprofits could apply for grants to acquire land or permanent protections (such as conservation easements), requiring them to contribute matching funds from non-state sources. The bill also establishes a separate program to incentivize community-led projects that reduce air pollution. These grants would require recipients to grant perpetual easements restricting land use to green space purposes and undergo state audits.
