It is designed to encourage both public and private sector commercial and mixed-use projects in Portland and Oregon to meet LEED certification. A working group of public and private sector stakeholders, facilitated by the City’s Office of Sustainable Development, developed the Portland Supplement in 2000-01. In 2001, the City adopted a Green Building Policy requiring new construction and major renovations of all city facilities meet the Certified level of LEED. While the Policy targets all new construction and major retrofits of city owned facilities, the City recognizes that LEED 2.0 is not appropriate for every building type and programming need. Therefore the Policy was designed to include a variety of tools targeted at specific building types including tenant improvements (T/I) and operations and maintenance practices when they become available. In addition, a list of exempted building types is currently being developed for city-owned buildings that aren’t appropriate for LEED 2.0 certification (small out buildings, sheds, pump stations, etc.). In 2001, the Portland Development Commission adopted a similar policy requiring LEED certification for all publicly financed (over $200,000 in PDC financing) private sector projects larger than 10,000 S.F. Both policies are helping move environmental building practices and LEED certification forward in the Portland market. In addition, the Oregon Office of Energy recently expanded the state Business Energy Tax Credit (BETC) to include LEED Silver and higher rated buildings, providing a powerful incentive to developers and building owners to design and build to the LEED standard. The Portland Supplement to LEED helps meet local environmental objectives and streamlines regulatory requirements providing a powerful tool for increased market penetration of high performance, healthy commercial and mixed use buildings throughout Portland. Certification The City of Portland Supplement is a LEED guidance document. All projects must register with the U.S. Green Building Council (USGBC) and follow documentation and submittal requirements as described in the LEED Reference Package. USGBC will review each application in its entirety, including Portland-specific credit modifications and supplements. An additional processing fee may apply. Applicants must clearly note that they are using the City of Portland Supplement at the time of registration and within the application submittal (in the project narrative and on the application’s cover).

Requirement SS Prerequisite 1.0 Design to a site sediment and erosion control plan that conforms to Title 10, Erosion and Sedimentation Control, Section 10.30.020, and best management practices outlined in the City of Portland’s Erosion Control Manual. The plan shall meet the following objectives Prevent loss of soil during construction by storm water runoff and/or wind erosion, including protecting topsoil. Prevent sedimentation of storm sewer or receiving streams and/or air pollution with dust and particulate matter. Technologies & Strategies The City of Portland’s Erosion Control Manual lists numerous measures such as silt fencing, sediment traps, construction phasing, stabilization of steep slopes, maintaining vegetated ground cover, and providing ground cover that will meet this prerequisite. PORTLAND LEED SUPPLEMENT –REQUIREMENTS & RESOURCES Portland LEED Documentation Submittals Submit the Erosion Control Plan that was approved by the City of Portland Office of Planning and Development Review (OPDR) including construction document sheets referring to description and placement of erosion control measures, with the erosion control measures highlighted. Submit the Inspection Log required by the Erosion Control Plan. See Title 10, Section 10.30.020 for specific requirements. Related City of Portland Standards The City of Portland prohibits sediments or pollutants from leaving a construction site. See Title 10, Section 10.30.020 for specific requirements. The city’s Erosion Control Manual lists a variety of Best Management Practices to reduce pollutant and waste from leaving a construction Call 503-823-6892 for a copy.
