The community garden on S. Four Mile Run Drive will grow by almost 10,000 square feet, giving space for 40 new gardeners to grow herbs, fruits, vegetables and flowers.

The Arlington County Board unanimously approved the garden’s expansion, entering into agreements with the Northern Virginia Regional Park Authority — which owns the land — and Dominion Power, which runs power lines above where the garden expansion will be.

“What a great example of thinking outside the box to find solutions,” County Board Chair Mary Hynes said in a press release. “This is a win-win for everyone. Not only will the County be able to provide more garden plots, the space is currently overrun with invasive plants, which will be removed when the garden is built by Parks and Recreation staff.”

The expansion will tack on 9,900 square feet to the garden, which is directly adjacent to the W&OD Trail, and across the street from the Department of Motor Vehicles.

The garden will be on the NVRPA’s land, and as part of the agreement, if the park authority deems it needs the space, or the garden is encroaching too much on trail users, it can terminate the agreement with 60 days’ notice. The county is responsible for maintaining the garden, and the gardens are each run by a community association and an appointed “chief gardener.”

The expansion will add space to help whittle down the ever-expanding waiting list of gardeners hoping to use county space to grow their plants, a recommendation of the Urban Agriculture Task Force. According to the county, there are about 350 people on waiting lists for plots and half-plots of space at one of Arlington’s seven community gardens.

One plot costs $60 a year with water and $50 without water. The expansion will bring the total number of plots in county gardens to 265. Full 20-foot-by-20-foot plots are given on a first-come, first-served basis, and those interested in joining the waiting list can apply online.
