Watershed restoration is a set of tools and strategies used by Prince George's County (County) Department of the Environment (DoE) to combat stormwater pollution. The County and the Clean Water Partnership (CWP) have been implementing restoration projects throughout the County. The Clean Water Map details our efforts of restoring the County's watersheds.

This website details the restoration planning by DoE. Please click the link below to jump to the topic area of interest.

The County is continuing its commitment to watershed restoration with the development of two Patuxent River Restoration Plans. DoE received a grant from Maryland Department of the Environment (MDE) Water and Science Administration (WSA) to develop comprehensive watershed restoration plans for the Patuxent River watershed. The County is conducting a public information meeting about the Patuxent River Restoration Plans on August 27, 2019. See the Public Engagement and Watershed Restoration Plans sections below for more details.

Public Engagement

2019 Local TMDL Restoration Plan Public Meeting

DoE held a public meeting to inform and engage the community in the County’s development of the latest local TMDL restoration plans that met the County’s permit requirements under their 2014 National Pollutant Discharge Elimination System (NPDES) permit. The meeting provided an opportunity for the public to directly pose questions regarding the proposed restoration activities. See below for meeting materials for this public meeting.

2019 Western Branch Public Meeting

DoE held a public information meeting for County citizens and stakeholders to learn about the Western Branch Restoration Plan. At the meeting, DoE explained the draft plan and described on-the-ground practices and programmatic strategies that will need to be implemented to meet pollutant reduction goals.

2014 Local TMDL Restoration Plan Public Meetings

DoE held two public informational meetings in July 2014 and an additional public meeting in November 2014 to inform and engage the community in the County’s development of the five local TMDL restoration plans that met the County’s permit requirements under their 2014 National Pollutant Discharge Elimination System (NPDES) permit. The meetings also provided an opportunity for the public to directly pose questions regarding the proposed restoration activities. See below for meeting materials for these public meetings.

Watershed Restoration Plans

A total maximum daily load (TMDL) establishes the maximum amount of a pollutant that waterbody can receive while still meeting state water quality standards. The restoration plans are strategies for addressing and managing urban stormwater (i.e., water from rainstorms) to restore and protect the County's water bodies. The plans for each of the local watersheds includes requirements to meet the U.S. Environmental Protection Agency- (EPA-) approved TMDL and the Chesapeake Bay TMDL requirements.

In 2010, EPA established the Chesapeake Bay TMDL. Each state in the Chesapeake Bay watershed were required to develop Watershed Implementation Plans (WIPs) that serve as a guide for meeting the pollution-reduction targets in the Chesapeake Bay. So that Maryland can inform EPA about actions taken to reduce pollution in the state, MDE included the requirement to develop restoration plans in the County's NPDES Municipal Separate Storm Sewer System (MS4) permit.

In 2014, the County developed and is currently implementing restoration plans that serve as blueprints for improving water quality and meeting pollutant reduction goals called for in approved local TMDLs. Each plan describes the pollutants and sources of those pollutants specific to each water body, the land uses and natural features in the watershed, a method for determining the amount of pollutant reductions that need to be achieved and targeted pollutant reduction strategies for each watershed. The strategies include both programmatic initiatives (e.g., pet waste campaign, street sweeping) as well as on-the-ground, pollution-reducing best management practices (BMPs).

The County is continuing to perform restoration planning. In 2018, a restoration plan was developed for the Western Branch watershed. The County is developing additional restoration plans to address local TMDLs in the Lower Patuxent, Middle Patuxent, and tidal Patuxent River watersheds.

Watershed Assessments

The County's MS4 permit requires watershed assessments. The County completed its comprehensive watershed assessment report 2018. Prior to this, the County developed Watershed Existing Conditions Reports for the watersheds that have EPA-approved TMDLs in 2014. The reports began the watershed assessment process with a compilation and inventory of available information. Links to the 2018 countywide watershed assessment and the 2014 documents are below.

Factsheets for TMDLs within Prince George’s County

DoE developed factsheets that summarize each EPA-approved TMDL in the County. Click on the name of the watershed or pollutant name below to review the TMDL factsheet. Complete TMDL reports may be obtained from the MDE TMDL website.
