RE: Draft Sustainability Guide of Existing and Historic Properties

Dear Julianna Jackson:

Casey Trees is a Washington, DC-based nonprofit with a mission “to restore, enhance, and protect the tree canopy of the nation’s capital.” To fulfill this mission, we plant trees; monitor the city’s tree canopy; and work with city officials, developers, and residents to prioritize trees. We are committed to helping the District reach its 40 percent tree canopy goal by 2032. Therefore, we appreciate the opportunity to provide input on the draft Sustainability Guide of Existing and Historic Properties (Sustainability Guide) compiled by the District of Columbia Office of Planning.

The District’s oldest trees contribute to the historic character of homes, buildings, and redevelopment projects, while new trees planted on historic sites will grow to help our city achieve its sustainability goals. The Sustainability Guide has the potential to serve as a tool to protect trees on historic properties. These trees are one of our community’s most valuable amenities as they reduce cooling costs; clean air; improve mental wellbeing; and help to manage pollution, flooding, erosion, and extreme temperatures.

We are pleased to see tree preservation and tree planting included in the Sustainability Guide as low-cost strategies for green retrofits. To further incorporate the codes, city plans, and resources pertaining to trees in the District, we recommend the following:

In the Landscaping section on page 44, include the benefits of urban trees, such as those listed on page 8 of Casey Trees’ Citizen Advocate Handbook. These include shade, climate change mitigation, and stormwater management.

Thank you for the opportunity to comment. If you have any questions about these recommendations, please feel free to contact me at ktaddei@caseytrees.org.

Sincerely,
Kristin Taddei
Planning Advocate
