The Portland City Council adopted Ordinance #185610 on September 12, 2012 directing the Bureau of Environmental Services (BES) to start directly billing drainage district customers for stormwater management services on July 1, 2013.
The ordinance directs BES to phase in stormwater management charges over four years starting with 25% of the approved charge beginning July 1, 2013. The rate will increase 25% every year on July 1 until drainage district customers are paying 100% of the off-site stormwater management charge beginning on July 1, 2016. The city will not bill drainage district customers for on-site stormwater management.
Starting July 1, 2014 the stormwater off-site rate for drainage district customers increased to 50% of the City Council adopted rate.
On City of Portland water/sewer utility bills received after July 1, 2014, the new multi-family off-site stormwater management rate adopted by City Council is $6.97per 1,000 square feet of impervious area (IA) per month for all City of Portland ratepayers outside of the drainage district boundaries.
For Pen 1, Pen 2 and Multnomah County ratepayers the rate is $3.48 (50% of the off-site stormwater management rate) per 1,000 square feet of IA. Monthly rates are based on days of service and may vary with each bill.
On City of Portland water/sewer utility bills received after July 1, 2014, the new commercial off-site stormwater management rate adopted by City Council is $7.27 per 1,000 square feet of impervious area (IA) per month for all City of Portland ratepayers outside of the drainage district boundaries. For Pen 1, Pen 2 and Multnomah County ratepayers the rate is $3.64 (50% of the off-site stormwater management rate) per 1,000 square feet of IA. Monthly rates are based on days of service and may vary with each bill.
With the start of stormwater management charges for drainage district customers, the Portland Harbor Superfund line item on bills increased slightly. The Superfund charge is not a new charge. In July 2007, the city added a Portland Harbor Superfund Program line item to the city sewer bill to show ratepayers exactly what portion of their sewer bills pay for the Portland Harbor investigation. City of Portland sewer rates have paid the city's share of this investigation since 2001.
The Superfund charge is based on both impervious area (IA) and sewer volume (measured in hundred cubic feet, or CCF). The Superfund charge for the 2014-2015 fiscal year is $0.10 per each thousand square feet of IA and $0.04 per each CCF of billed sewer volume. Ratepayers in the drainage district have not paid the stormwater portion of this charge because the city has not billed directly for stormwater management.
