A. Demolition. Demolition means removal of the entire superstructure down to the subflooring, such that none of the existing superstructure is maintained. Demolition includes removal of all exterior walls. It also includes alteration, abandonment or removal of all of the existing perimeter foundation.
B. Major Residential Alteration or Addition. Major alteration or addition means doing any of the following:
1. adding any new story, including a basement or other below-grade structure. Raising a structure to meet the required headroom in a basement is considered the same as creating a basement,
2. increasing or replacing 50 percent or more of the exterior wall area on any floor. If the subflooring under an exterior wall is removed, it will be treated as if the wall was removed,
3. adding total new floor area to the existing structure that exceeds 800 square feet, or
4. adding an area exceeding 100 percent of the existing foundation footprint area of the structure.
C. Recognized organization. Recognized organization includes neighborhood coalitions and neighborhood associations recognized by the Portland Office of Neighborhood Involvement.
D. Subflooring. Subflooring means the bottom-most structural floor laid as a base for a finished floor.
E. Superstructure. Superstructure means the part of the building or construction entirely above its foundation or basement.
F. Demolition Manager. Demolition manager means the person designated by the property owner or demolition permit applicant who will be responsible for implementing and overseeing the Demolition Plan and who will be the contact person for BDS and other regulatory agencies regarding the Demolition Plan. The Demolition Manager must complete training and be an accredited inspector, as that term is defined in OAR 340-248-0010(1), unless the Demolition Manager designates another person who has the training and is an accredited inspector and who is on-site during all mechanical demolition and deconstruction activities. The Demolition Manager must have knowledge regarding erosion and sediment control, site control, and proper handling of materials generated from the demolition activities. The Demolition Manager is a “responsible party” as defined in this Section 24.55.150.
G. Demolition Plan. Demolition plan means the plan signed by the Demolition Manager that outlines the techniques and equipment that the Demolition Manager will use on the demolition site to control dust and debris generated during the demolition activities. The Demolition Plan must also include the anticipated timeframe for the demolition, a description of the site control measures set forth in Section 24.55.205 C. and monitoring processes that will be followed on the site before, during, and after the demolition activities, details of pedestrian protection where required, and a description of how the site will be secured against accessibility by any unauthorized persons. The Demolition Plan must include erosion and sediment control measures required by this Chapter 24.55, Title 10 and Chapter 17.39 of the Portland City Code, the City of Portland Erosion and Sediment Control Manual, the City of Portland Source Control Manual, and any other City of Portland regulations governing erosion, sediment control, stormwater control, or wastewater generated from the demolition activities covered by this Section 24.55.205. The Plan must also include contact information for the Demolition Manager.
H. Mechanical demolition activities. Mechanical demolition activities means pulling down any part of a structure using mechanical tools such as cranes, bulldozers, excavators, rams, or similar heavy machinery.
I. Deconstruction. Deconstruction means demolition via the systematic dismantling of a structure or its parts, typically in the opposite order it was constructed, which can include the selective use of heavy machinery.
