Converting a Small Leaking Pond to a Seating Area with Shade Tree

A Northern Virginia townhouse owner wants to remove a leaking 5×4-foot goldfish pond, fill the hole, and create a paved seating area with slate or brick. They also want a fast-growing shade tree for a tiny backyard (23×8 feet). A birch was considered but may be too large.

Pond Removal & Backfill

1. Drain completely.
2. Remove liner and all debris.
3. Backfill with native soil in 6-inch lifts, lightly compacting each layer.
4. Top with 2–3 inches of quality topsoil or compacted gravel base for paving.

Paving Choice: Slate vs. Brick

• Brick (clay pavers): More economical, easier to install on sand setting bed, widely available in modular sizes.
• Slate (flagstone): Higher material cost, irregular shapes require more cutting/fitting, but elegant natural look.
• Budget tip: Use brick for the main area, slate accents only.

Tree Selection for Tiny Yard

Oaks and maples are too large. Better small, relatively fast-growing options for Zone 7a:

• Redbud (Cercis canadensis): 20–30 ft, spring flowers, heart-shaped leaves, moderate growth.
• Serviceberry (Amelanchier spp.): 15–25 ft, white spring blooms, edible berries, fall color.
• Japanese maple (Acer palmatum): 15–20 ft, spectacular foliage, slower but high impact.
• Crepe myrtle (Lagerstroemia): 15–25 ft, summer flowers, exfoliating bark, many dwarf cultivars.

Consult the Virginia Cooperative Extension or a local nursery for site-specific recommendations.
