660-012-0415 Parking Maximums and Evaluation in More Populous Communities (1) Cities with populations over 100,000, counties with populations over 100,000 outside city limits but within the urban growth boundary, and cities with populations over 25,000 within the Portland Metropolitan Area, shall set parking maximums in climate-friendly areas, and in Metro Region 2040 centers. Those cities and counties shall also set parking maximums on lots or parcels within the transit corridors and rail stop areas listed in OAR 660-012-0440. Cities and counties that have designated priority transit corridors under OAR 660-012-0710 may set parking maximums in those corridors in place of the corridors identified in OAR 660-012-0440(3)(b) and (c). (a) Parking maximums shall be no higher than 1.2 off-street parking spaces per studio unit and two off-street parking spaces per non-studio residential unit in a multi-unit housing development in climate-friendly areas and within one-half mile walking distance of priority transit corridors. These maximums shall include visitor parking; (b) Parking maximums shall be no higher than five spaces per 1,000 square feet of floor space for all commercial and retail uses other than automobile sales and repair, eating and drinking establishments, and entertainment and commercial recreation uses; (c) For land uses with more than 65,000 square feet of floor area, surface parking may not consist of more area than the floor area of the building; and (d) Non-surface parking, such as tuck-under parking, underground and subsurface parking, and parking structures may be exempted from the calculations in this section. (2) Cities with populations over 200,000 shall, in addition to the requirements in section (1) of this rule: (a) Study the use of priced on-street timed parking spaces in those areas listed in OAR 660-012-0435(2) and OAR 660-012-0440(2) and (3). This study shall be conducted every three years or more frequently. Cities shall adjust prices to ensure availability of on-street parking spaces at all hours. This shall include all spaces in the city paid by minutes, hours, or day but need not include spaces where a longer-term paid residential permit is required; (b) Use time limits or pricing to manage on-street parking spaces in an area at least one year before authorizing any new structured parking on city-owned land including more than 100 spaces in that area after March 31, 2023; (c) Adopt procedures ensuring prior to approval of construction of additional structured parking projects of more than 300 parking spaces designed to serve existing uses, developer of that parking structure must implement transportation demand management strategies for a period of at least six months designed to shift at least 10 percent of existing vehicle trips ending within one-quarter mile of the proposed parking structure to other modes; and (d) Adopt design requirements requiring applicants to demonstrate that the ground floor of new private and public structured parking that fronts a public street and includes more than 100 parking spaces would be convertible to other uses in the future, other than driveways needed to access the garage.
