Comprehensive Watershed Management Plan
Loudoun County Watershed Management
With assistance from a grant from the U.S. Environmental Protection Agency, a comprehensive watershed management plan (CWMP) report was completed for Loudoun County, Virginia in September 2008. The report provides a recommended approach for Loudoun County Government to develop a plan to manage, preserve, and improve the watersheds and water resources of Loudoun County.
Importance of Conservation
Much of the eastern part of Loudoun County consists of generally urban and suburban development, while the western portion has a more rural setting with farms, towns, and a growing number of residential subdivisions. Over the past decade, Loudoun has been ranked among the fastest growing counties in the nation. In response to the rapid changes in land use, the Loudoun County Government and citizen stakeholders recognized that watershed management planning was needed to help protect the county’s water resources - resources that are vital to economically and environmentally healthy communities.
The national engineering and environmental consulting firm CH2M Hill, Inc. was contracted by the county in August 2007 to:
- Evaluate existing hydrologic data
- Evaluate existing watershed data
- Prepare a watershed management program plan for Loudoun County with recommendations and options for implementation
Loudoun County Government staff compiled, organized, and conducted basic statistical analyses on available hydrologic and water quality data and provided it to CH2M Hill. View a presentation of the analysis and results
With assistance from county staff and a county-wide stakeholder group, CH2M Hill organized and analyzed existing data to characterize and categorize subwatersheds into several potential management groups. Approximately 90 specific watershed management plan recommendations or tasks were listed. View the comprehensive watershed management plan
The CWMP project was the next phase of watershed management planning after the Strategic Watershed Management Solutions (SWMS) strategic plan. The scope of the contract work was consistent with the recommendations from the SWMS report and the EPA grant work plan. CH2M Hill presented a summary of their evaluation of the hydrologic data at the June 10, 2008, Board of Supervisors Transportation / Land Use Committee (TLUC) meeting.
Loudoun County Government staff, the Board of Supervisors-appointed Water Resources Technical Advisory Committee,and the independent, community-based Watershed Management Stakeholder Steering Committee evaluated the CWMP report recommendations and provided the county’s elected officials with their suggestions on which tasks should be considered priorities for Loudoun County Government to evaluate further or implement.

Implementation of the watershed program and the specific recommendations will help enhance and protect human health and the environment by assuring adequate, sustainable, clean, and safe water in the presence of continued development.
