There’s nothing like a magnolia tree to cover up sewage. Arlington County is slated to spend about $800,000 to landscape around a sewage treatment plant if the county board approves the contract Saturday.

The plan includes about $450,000 for flowers and trees of all shapes and sizes, about $50,000 for topsoil, $3,000 for dead tree removal, a $16,000 retaining wall and a $14,000 permeable walkway — a sidewalk that allows more rainwater to enter the soil instead of running off.
