Climate impact resilience principles incorporated into planning for new, repair, and replacement 
of infrastructure.   

The MS4 and TMDL Watershed Implementation Plan (WIP) presents strategies to meet the 20% 
impervious restoration requirement and Total Maximum Daily Load (TMDL) waste load allocations for 
each receiving water body. The complete plan is available on DPW’s website at cleanwater.org website.   
DPW established a reporting framework that will be used for annual reporting as required in the City’s 
National Pollutant Discharge Elimination System (NPDES) MS4 Permit. DPW identifies and conducts 
necessary maintenance, adaptive management, staffing, and financial strategies to implement the WIP.  

DPW provides Best Management Practices (BMPs) to restore an equivalent 20% of the existing 
impervious area where stormwater runoff is currently not managed to the maximum extent practicable 
(MEP). DPW will continue to educate and involve residents, businesses, and stakeholder groups in 
achieving measurable water quality improvements.   

Performance Measures & Results 

The City’s proposed approach for meeting the 20% restoration requirements will account for significant 
reductions of nitrogen, sediment and phosphorus.  The majority of the construction work will be 
completed in the last 18 months of the permit period from July 2017 to December 2018.  

To meet the 20% restoration goal, the City will restore over 4,291 acres of impervious surface area by 
the end of the current permit period, using a diverse approach throughout the City.  This will include 
installing stormwater management projects, employing a variety of operational programs, such as 
mechanical street sweeping, preventive inlet cleaning, and illicit discharge detection and elimination; 
and fostering partnerships to encourage stormwater management implementation on private lands, 
coupled with an increase in environmental stewardship within the communities.  

In November of 2014, the Baltimore City Department of Public Works (DPW) created the Stormwater 
Advisory Committee (SWAC).  The purpose of SWAC is to advise the Department on stormwater 
projects, programs, and issues, and to help educate stakeholder groups on related matters.  To date the 
Advisory Committee has reviewed and provided comment on: 

 -The City's Municipal Separate Storm Sewer System (MS4) Watershed Implementation Plan, 
which guides DPW's capital improvement projects for stormwater management and stream 

-Stormwater fee regulations for port industries; SWAC is made up of volunteer members 
representing a diversity of sectors, including environmental non-profits, businesses and 
industries, anchor institutions and citizens.  

-Proposed changes to the State's stormwater fee legislation; -DPW's stormwater utility fund and 
how stormwater fees are used to improve water quality; and on  

-the Clean Water Baltimore website and associated educational material.  

In January 2015, DPW and the Mayor’s Office of Employment Development, together with the 
Chesapeake Water Environment Association (CWEA), launched the Baltimore City Water Industry Career 
Mentoring Program.
