The July 8, 2019 flash flooding incident devastated Donaldson Run’s Tributary, exposing the flaws in Donaldson Run’s Tributary B restoration design. The County also is now on a path to use that same fundamentally flawed approach at Gulf Branch.
Killing a Stream to “Restore” a Stream
So-called “stream restorations” frequently kill streams by increasing water temperature and reducing oxygen. Cutting down trees and existing vegetation and using excavators to disturb the land in or near a streambed simply compound the problem and unleash invasive plants that also negatively impact stream ecology.
Studies show that the underlying cause for urban stream syndrome — the trigger for these “restoration” projects in the first place — is the growing volume and speed of stormwater runoff that results from the proliferation of impervious surfaces:
The ultimate mechanisms by which urbanization degrades streams are manifold but can usually be attributed to a small number of landscape-scale land-use practices for which alternative management approaches are available….
Our analyses reveal urban stormwater as a new class of environmental flow problem: one that requires reduction of a large excess volume of water to maintain riverine ecological integrity
County government disregards climate science
Instead of addressing the underlying problem, Arlington continues to spend millions on outdated, cookie-cutter “restoration” plans that produce counterproductive outcomes. The Donaldson Run Tributary A project is a prime example:
[A] large number of stream restoration projects focus primarily on physical channel characteristics. We show that this is not a wise investment if ecological recovery is the goal. Managers should critically diagnose the stressors impacting an impaired stream and invest resources first in repairing those problems most likely to limit restoration.
Since 2011, scientists and others have shown that the types of “restoration” projects conducted here in Arlington and elsewhere fail to achieve basic ecological and water quality goals.
Many streams are chosen for restoration simply because they are the “low hanging fruit.” This occurs when engineers–rather than ecologists, naturalists and conservation biologists–control a project. After the damage is done, those tasked with protecting natural resources are given the impossible task of trying to restore a semblance of life, natural
functionality, and ecological balance to a seriously degraded, post-construction landscape.
Streams will try to restore themselves (for example, trees falling into the water provide resistance and can slow water down). But to truly restore a stream, you must first reduce the inputs (the volume and speed of the runoff entering the stream). Otherwise, any benefits from so-called restoration efforts will be quickly nullified, as the Baltimore Sun reported:
[S]ome scientists say controlling erosion[‘s] … benefits don’t last if nothing else is done to reduce runoff from development before it pours into the stream.
“You can’t ask a stream to do everything an entire watershed should do,” said Margaret A. Palmer, a University of Maryland scientist who’s researched restoration ecology. She’s published studies finding “no consistent evidence” that restored streams reduce nitrogen, another key pollutant fouling the bay.
And while stabilizing stream channels may reduce erosion at first, she said, the benefit is likely to decrease over time.
In addition to the ecological impacts, misguided stream “restoration” efforts can also exacerbate flash flooding. By continuing to dump greater and greater volumes of water into the stream system — a system not designed to receive all that water so rapidly — County government ensures that erosion and other problems plaguing the streambed will continue. Widening the channel will do little to alter these dynamics.
County government is poised to repeat past mistakes by replicating them at Donaldson Run Tributary B and at Gulf Branch. Papering over development and land-use problems by merely adjusting stream channels to manage greater volumes of runoff won’t work. Both these “restoration” projects should be halted until a revised, ecologically sound design is adopted.
County government must accept current climate science and directly address the stormwater runoff problems before attempting expensive stream restoration projects. County government must redesign these projects to fit within a sustainable environmental footprint.
Working harder to preserve Arlington’s remaining mature tree canopy, reducing the quantity of impervious/built surfaces, and focusing greater attention on conservation of our natural resources are the keys to cost-effective stormwater management.

Synetic Theater Camps are a wildly fun, highly accessible choice for young people who love moving, playing games, and making memories. Registration is open now for Summer Camps (sessions June 20-August 25) and there are even a few spots left for Spring Break camp, April 3-7.
Located in National Landing, these performance-based camps are designed for students of all ages – no theater or performance experience required.
Led by professional teaching artists, campers learn acting, movement, and technical theater skills through the lens of Physical Theater. Physical Theater incorporates acting, movement, dance, mime, and acrobatics. If you’ve seen a Cirque du Soleil performance, you’ll find many similarities.
Most first-time campers are new to the performing arts, and teaching artists are well-versed in engaging students at all levels. Parents and campers report that one of the best parts of Synetic is the community, with many families returning year after year because they feel a strong sense of belonging.
