Delivering Projects using Community Based Partnership to meet Chesapeake Bay TMDL Requirements in Prince George’s County, MD and Key Lessons Learned

Prince George’s County, MD is located within the 80,000 square mile Chesapeake Bay watershed.  The Bay TMDL requires States, Counties and Cities within the watershed to limit the amount of Total Phosphorus, Total Nitrogen and Total Suspended Sediment that is discharged through point and non-point sources (urban stormwater runoff). Prince George’s County (County) and Corvias Infrastructure Solutions (CIS) developed the Clean Water Partnership (CWP) to design, build and maintain urban stormwater quality treatment best management practices (BMPs) to meet the County’s Bay TMDL obligations. Bringing financing, engineering design firms, contractors, outreach and social/economic goals to this project, environmental compliance is being achieved with local economic growth and community involvement. This groundbreaking and innovative alternative delivery method is the first in the country.  The two main CBP program elements include:

• Environmental goals of design, permitting and construction of stormwater treatment devices, to treat urban stormwater runoff.
• Social and economic goals to meet aggressive target class utilization (40% for local, small and minority businesses) and local workforce (51% county resident utilization).

CWP has successfully implemented over 150+ projects, certified over 300+ BMP devices to help meet the County's MS4 stormwater permit requirements. In this process, CWP spent $140+ million in design and construction and reduced approximately 53,700 lb. of TN, 7,300 lb. of TP and 4,405,100 lb. of TSS. In addition, more than 15,000 acres of drainage area is also treated to reduce pollutants. Primary program metrics focused on schedule/speed, scale economies and performance, community outreach, local disadvantaged subcontractor utilization, local subcontractor development, workforce utilization, and workforce development. Additional metrics were related to alternative compliance and partner programs, and project budget books and schedules. This presentation will provide useful information for utility and public works department leaders, and stormwater management staff about creating a program to meet large-scale targets for capital project delivery intended to meet water quality goals or other stormwater related objectives such as resiliency and flood risk reduction. Partnership goals, organizational structures and integrated delivery partners roles and responsibilities, and program metrics will be shared for discussion.
