The purpose of this chapter is to provide an appropriate and efficient review process for evaluating modifications to existing developments or land use approvals.
This chapter applies to all proposals to modify an existing or proposed use, structure, site improvement, or condition of approval—for existing developments or land use approvals—when initially approved through one of the land use applications listed below:
This chapter also applies to all proposals to modify an existing development that was not subject to city approval when developed but would be subject to city approval, through one of the land use applications listed in Paragraph 18.765.020.A.1 through 4, if proposed for development under current city regulations.
This chapter does not apply to proposals to modify a condition of approval where the modification is subject to the provisions of Paragraph 18.20.050.E.4.
This chapter does not apply to proposals to modify an urban forestry plan where the modification is subject to the provisions of Subsection 18.420.060.F.
The Director will determine the most appropriate review type for the proposed modification. In addition to Subsection 18.710.040.D, the Director's determination will consider whether the proposed modification involves any of the following:
Allowed modifications involve the application of clear and objective standards that do not require the exercise of professional judgment about technical issues. These modifications do not require land use review.
Minor modifications involve the exercise of professional judgment about technical issues as they relate to the application of clear and objective or discretionary standards or approval criteria. These modifications require Type I land use review.
Major modifications involve the exercise of limited discretion as they relate to the application of clear and objective or discretionary standards or approval criteria. These modifications require Type II land use review.
A minor or major modification land use review is limited in scope to an evaluation of the modification's compliance with applicable standards and the degree of impact, if any, on surrounding properties, sensitive lands, or public facilities.
A proposed modification involving a nonconforming use or development is subject to the provisions of Chapter 18.50, Nonconforming Circumstances, in addition to the provisions of this chapter.
A proposed modification that constitutes substantial redevelopment, as determined by the director, requires submittal of a new land use application rather than a modification application.
It does not cause the development to go out of conformance with any applicable standard or further out of conformance if already nonconforming, except where an adjustment has been approved; and
Installation of mechanical equipment that does not involve the removal of any parking spaces or landscaping and where screening standards are met as provided in the applicable development standards chapter in 18.200 Residential Development Standards or 18.300 Nonresidential Development Standards.
It does not cause the development to go out of conformance with any applicable standard or further out of conformance if already nonconforming, except where an adjustment has been approved; and
It does not require a technical study, such as a full transportation impact analysis, although it may require minor technical memos such as stormwater analysis.
Approval criteria. The approval authority will approve or approve with conditions a minor modification application when all of the following criteria are met:
It does not cause the development to go out of conformance with any applicable standard or further out of conformance if already nonconforming, except where an adjustment has been approved; and.
The operating and physical characteristics of the modified development are reasonably compatible with surrounding properties, sensitive lands, or public facilities;
If the proposed modification involves development that has nonconforming structures or site improvements and exceeds the project valuation threshold listed in the city's Master Fees and Charges Schedule, the development will be improved as required by Subsection 18.765.070.E; and
Modifications to nonconforming development. The purpose of these provisions is to require existing development with nonconforming structures or site improvements to come into conformance with city standards gradually as structures or site improvements are modified over time. These provisions also give applicants the choice of making improvements that support pedestrians—in lieu of making improvements to come into conformance—in order to advance Tigard's vision to become a walkable, healthy, and inclusive city.
Development with nonconforming structures or site improvements is required to come closer or fully into conformance with all applicable development standards when the total project valuation of all proposed modifications equals or exceeds the amount listed in the city's Master Fees and Charges Schedule. The method for calculating total project valuation is as follows:
The applicant must demonstrate that a minimum of 10 percent of the total project valuation is being used to bring the development closer into conformance with all applicable development standards, except where:
The cost to complete all required improvements exceeds 10 percent of the total project valuation, in which case the applicant must demonstrate that a minimum of 10 percent of the total project valuation is being used to bring the development closer into conformance with one or more development standards of the applicant's choosing.
The applicant may choose to satisfy the requirements of Paragraph 18.765.070.E.2 by providing improvements that support pedestrians in lieu of bringing the development closer into conformance with all applicable development standards.
Pedestrian improvements must provide a new site or building element or enhance an existing site or building element. Improvements involving maintenance or repair of existing site improvements or structures do not satisfy this provision; and
Pedestrian improvements must be located in the public right-of-way or within 20 feet of a street property line. Improvements must not contravene any applicable standard and must fall into one of the following categories:
Installation of approved trees in the right-of-way or along the street property line to further separate pedestrians from parking areas or vehicle travel lanes and to provide weather protection.
Pedestrian-scale architectural features such as window trim, awnings, wall trellises, or any permanent feature that reduces the visual impact of blank, flat, or long building walls; and
