Watershed Planning

Watershed Management Plan

In July 2009, the City of Falls Church began to develop a Watershed Management Plan. Through a comprehensive stakeholder process the City developed an integrated watershed management plan (see above). The consulting firm, AMEC, Inc., was retained to work with staff and stakeholders through this process. To accomplish the stakeholder involvement desired for this process the City formed a Watershed Advisory comprised of representatives from various sectors of the community. The group met seven times during the course of the year to provide input into the project.

The Watershed Management Plan established a roadmap for restoring and maintaining a healthy, sustainable aquatic ecosystem in the Tripp's Run and Four Mile Run watersheds while providing adequate flood control and the safe management of stormwater runoff. The array of actions proposed by the plan included: policy and ordinance changes; staff additions; programmatic changes to the city's stormwater program; design and construction of 11 projects around the City; and creation of a dedicated funding stream for the City's stormwater program. In February 2012, City Council adopted the Watershed Management Plan.

Draft Chesapeake Bay TMDL Action Plan

In 2010, the EPA established the Chesapeake Bay Total Maximum Daily Load (TMDL), a comprehensive pollution diet for the Chesapeake Bay with accountability measures to restore clean water in the Bay and local streams and rivers.

The Chesapeake Bay TMDL requires The City of Falls Church and other Municipal Separate Storm Sewer System Permit Holders to achieve specific nutrient and sediment reductions—defined in terms of pounds of sediment, phosphorus, and nitrogen—through local stormwater management programs. As established by the Virginia Department of Environmental Quality (DEQ), The City of Falls Church must reduce its share of TMDL pollution by 5% during the current MS4 permit cycle (2013–2018), an additional 35% (40% total) during the second permit cycle (2018–2023), and the final 60% (100% total) during the third permit cycle (2023–2028).
