Clean, healthy streams are important for protecting people, plants, insects and other animals that call these watersheds home. As in many urban areas, the health of our streams and waterways is threatened.This is due largely to the increased pollution from human activities and the increased amount of impervious surfaces.
Report pollution or illegal dumping by calling our hotline at 240-314-8348.
The City of Rockville contributes drainage to three watersheds: Cabin John Creek, Watts Branch and Rock Creek. All of Rockville's watersheds are part of the greater Potomac River Basin, which itself drains into the Chesapeake Bay.
Cabin John Watershed
In 2011, the city contracted a watershed study designed to help prioritize projects and programmatic activities over the next ten years.
In 2013, the city completed a management plan to identifying additional stormwater management (swm) opportunities and stream restoration projects, Environmental Site Design opportunities and constraints for small-scale SWM features, and operational strategies that would complement the city’s ongoing watershed projects and operations.
The Phase 1 Green Streets Study, which began in Spring 2016, is a proactive project to equip City staff with the information and guidance needed to pursue a successful green streets program. Green streets, or green infrastructure projects, are stormwater management facilities installed in the public right-of-way. Example green street practices include curb extensions or bump-outs, bioswales, bioretention, stormwater trees and tree filters, and permeable pavement installations.
