City of Tigard, OR Chapter 18.660 Tigard Triangle Plan District

§ 18.660.010 Purpose.

The Tigard Triangle Plan District implements the land use and development vision for the Tigard Triangle as outlined in the Tigard Comprehensive Plan. It also advances Tigard's mission to become the most walkable city in the Pacific Northwest and supports the district's designation as a regional Town Center.

The Tigard Triangle Plan District Chapter is referred to throughout Chapter 18.660 as "this chapter." The standards and procedures of this chapter are designed to:

•	Remove regulatory and financial barriers for small-scale incremental development;
•	Streamline the development review and approval process;
•	Support existing development;
•	Support transitional uses and adaptive re-use of existing development;
•	Increase the diversity of goods and services available in the district;
•	Encourage new housing and mixed-use development;
•	Limit new auto-oriented development;
•	Preserve the district's unique and natural features, including but not limited to district trees;
•	Create safe, comfortable, and attractive streetscapes for pedestrians; and,
•	Improve connectivity for all modes of travel.

Collectively, the purpose of these standards and procedures is to facilitate the transformation of the Tigard Triangle into an active, urban, multimodal, and mixed-use district as envisioned by the 2015 Tigard Triangle Strategic Plan.

§ 18.660.040 Review Process.

A. Purpose. The purpose of this section is to streamline the development review and approval process.

B. Development review. Development review is the process whereby the applicant submits all required development permit applications to the city for review against all applicable standards. Depending upon the type of development proposed, permit applications may be submitted consecutively or concurrently. If land use review is required or initiated by the applicant pursuant to Subsection 18.660.040.C, land use approval must be obtained prior to submitting for development review.

1. Early assistance meeting. The applicant must request an early assistance meeting with the city prior to the submittal of any required building, site, or public facility permit application. The Director may waive this requirement for proposals that are not complex, would not benefit from a meeting with the city, or have had a pre-application conference as part of a related land use review.

2. Development review requirements. All proposed development must demonstrate compliance with the following requirements at the time of development permit application submittal:

a. Use and design standards. The proposed development conforms to all applicable use and design standards in this chapter, except as approved through the adjustment process as provided in Paragraph 18.660.040.C.4.

b. Transportation facility improvements. The proposed development will provide transportation facility improvements and mitigation at the time of development as determined by the transportation facility review process described in Paragraph 18.660.040.B.3.

c. Minimum public facility improvements. The proposed development provides or will provide public facility improvements at the time of development that conform to the city's minimum standards for safety and adequacy, which are as follows:

i. Frontage on, or approved access to, a public street.

ii. A minimum of 24 feet of pavement and horizontal clearance on a public street along each street frontage where access is taken. Additional transportation facility improvements may be required by Subparagraph 18.660.040.B.2.b.

iii. Adequate public utilities pursuant to the city's standards in the Public Works Design Manual and Sections 18.910.050 Easements, 18.910.090 Sanitary Sewers, and 18.910.120 Utilities. Section 18.910.120 may require undergrounding of utilities or a fee in lieu of undergrounding new or existing utilities.

iv. Adequate stormwater management facilities for water quantity and quality pursuant to Clean Water Services' standards and the city's standards in the Public Works Design Manual and Section 18.910.100 Storm Drainage.

3. Transportation facility review process. The transportation facility review process determines whether transportation improvements are needed and whether the proposed development will be required to construct or pay for them.

a. The following review process applies to all proposed developments, except those that are exempt from street frontage improvements (see Paragraph 18.660.020.B.2) or trigger a Transportation Impact Study (see Subparagraph 18.660.040.B.3.c).

i. The City Engineer will determine whether the proposed development is estimated to generate any new vehicle, pedestrian, or bicycle trips using the best available data and analysis, including but not limited to the ITE Trip Generation Manual or a Transportation Impact Study prepared by a transportation engineer licensed in the State of Oregon.

ii. If the proposed development is estimated to generate new trips, the City Engineer will evaluate the existing transportation facilities along each street frontage of the proposed development site for conformance with the transportation facility standards in Subsection 18.660.090.C. The City Engineer will also evaluate the entire development site for conformance with Map 18.660.B Transportation Network Map. If existing transportation facilities do not meet current standards, the City Engineer will identify needed improvements based on the transportation facility standards in Subsection 18.660.090.C.

iii. If transportation facility improvements are needed, the city will require construction of improvements and dedication of right-of-way at the time of development unless the city determines that such exactions are not roughly proportional to the number of new trips estimated to be generated by the proposed development. If the applicant disagrees with the city's proportionality determination, the applicant may utilize the city's Type II appeal procedure in Section 18.710.100 in a de novo hearing.

iv. The applicant may request to pay a fee in lieu of constructing the required transportation improvements as provided in Subsection 18.660.090.D.

b. The following review process applies to a proposed development that is exempt from street frontage improvements pursuant to Paragraph 18.660.020.B.2.

i. The City Engineer will determine whether the proposed development is estimated to generate any new trips as described in Subparagraph 18.660.040.B.3.a.i.

ii. If the proposed development is estimated to generate new trips, the City Engineer will identify needed improvements for the sole purpose of determining whether any additional public right-of-way is needed for future transportation improvements.

iii. If public right-of-way is needed for future transportation improvements, the city will require dedication of right-of-way at the time of development pursuant to Subparagraph 18.660.040.B.3.a.iii.

c. The following review process applies to a proposed development that triggers a Transportation Impact Study (TIS) as described below.

i. A TIS is required if the proposed development is estimated by the City Engineer to generate more than 1,000 new vehicle trips per day or impacts a state transportation facility as determined by the Oregon Department of Transportation. The applicant must pay the fee listed in the city's Master Fees and Charges Schedule for the city to conduct this study. The city will not accept any development permit or land use applications for review until the TIS has been completed and incorporated into the applicant's development permit or land use application submittal.

ii. The TIS will evaluate the existing transportation facilities for conformance with the city's transportation facility standards, including affected off-site facilities. If existing transportation facilities do not meet current standards, the study will identify needed improvements based on the transportation facility standards in Subsection 18.660.090.C and those of any other affected road authorities. If the TIS determines that transportation facility improvements are needed, the city will require construction of improvements and dedication of right-of-way at the time of development pursuant to Subparagraph 18.660.040.B.3.a.iii.

iii. If the TIS identifies off-site impacts from the proposed development, the applicant must submit a land use application as required by Paragraph 18.660.040.C.2 that complies with the provisions in Paragraph 18.660.040.C.3.

C. Land use review. Whether required by this title or initiated by the applicant, land use review precedes development review. Land use review is the process whereby the applicant submits any required or applicant-initiated land use applications to the city for review against all applicable approval criteria and standards. The provisions of Chapter 18.770, Planned Developments, do not apply to properties in the TMU zone.

1. Pre-application conference. The applicant must request a pre-application conference with the city prior to the submittal of any required or applicant-initiated land use application as required by Chapter 18.710, Land Use Review Procedures.

2. Land use applications. Required land use applications are shown in Table 18.660.1. If more than one land use application is required, they may be processed concurrently.

iv. Obtain all necessary approvals and permits from other applicable road authorities if the right-of-way to be improved is not under the city's jurisdiction.

b. Right-of-way must be dedicated to the public for transportation purposes in accordance with the standards in this chapter.

i. Additional right-of-way dedication may be required at intersections for needed improvements identified by a transportation impact study or applicable road authority. Where practicable or required, such as along 72nd Avenue, right-of-way provided for parking lanes may be used for intersection operational needs in lieu of additional right-of-way subject to approval by the City Engineer.

ii. Additional right-of-way dedication or public easements may be required to address slope or drainage issues as determined by the City Engineer in addition to the maximum right-of-way widths required in Tables 18.660.9–10.

c. Partial transportation improvements, also called half-street improvements, resulting in other than full improvements on both sides of the street are generally not acceptable. Partial transportation improvements may be approved where the city finds that it will be possible for the adjoining property to dedicate and improve the remainder of the street when it develops.

2. Intersection design and spacing.

a. Streets must generally intersect at right angles (90 degrees). Angles of less than 75 degrees are not allowed unless approved by the City Engineer. Streets must generally intersect so that centerlines are not offset.

b. Street intersections must have curb extensions to reduce pedestrian crossing distances, except on streets that do not have dedicated on-street parking lanes.

c. New street intersections, including alleys, not shown on Map 18.660.B Transportation Network Map are subject to approval by the City Engineer and require an access report. The City Engineer will specify the technical information that must be included in the report. At a minimum, the access report must show that the proposed street intersection meets stacking, sight distance, and deceleration standards provided in the Public Improvement Design Standards or the American Association of State Highway and Transportation Officials (AASHTO) publications, or other standards as determined by the applicable road authority.

d. Clear vision standards in Chapter 18.930, Vision Clearance Areas, and street spacing standards in Chapter 18.910, Improvement Standards, do not apply to street intersections in the TMU zone.

3. Transportation network connectivity.

a. Minimum required transportation improvements are shown on Map 18.660.B Transportation Network Map. Additional transportation improvements for network connectivity may be required by Subparagraphs 18.660.090.C.3.b and c. Alleys are encouraged but not required. Private streets are prohibited.

b. Block perimeters must be 2,500 feet or less in length as measured along the centerlines of streets, unless:

i. It is not practicable to construct a street due to topographical constraints, protected natural resource areas, or existing development patterns, and the applicant has submitted an adjustment application as provided in Paragraph 18.660.040.C.4 and obtained the necessary land use approval; or

ii. A future street, path, or trail on Map 18.660.B Transportation Network Map provides for a possible future connection that is feasible at the time of the proposed development and meets the block perimeter standard when included as part of the block perimeter measurement.

c. Bicycle and pedestrian connections are required where the addition of a connection would link the end of a permanent turnaround to an adjacent street or provide a midblock connection through a long block. A midblock connection is required where at least one block face is 800 feet or more in length. A required connection must go through the interior of the block and connect the block face that is 800 feet or more in length to its opposite block face. Bicycle and pedestrian connections include off-street trails and paths as described in Subsection 18.660.090.C.4.e.

c. Street trees.

i. Street trees are required along all street frontages. The minimum number of required street trees is determined by dividing the length (in feet) of the proposed development's street frontage by 40 feet. When the result is a fraction, the number of street trees required is the nearest whole number.

ii. Street trees must meet the standards in Section 2, Section 12, and Appendix 2 of the Tigard Urban Forestry Manual for tree size, spacing, maintenance, soil volume, and species. If tree wells are used, paving stones or Belgian blocks must be used to protect tree roots in lieu of metal or rubber grating.

iii. Street tree removal is subject to the city's tree removal permit process and the standards in Section 3 of the Tigard Urban Forestry Manual.

iv. Any Oregon white oak initially identified as a district tree, as defined in Subsection 18.660.070.H, that is located in the public right-of-way is regulated as a street tree and preserved where practicable.

d. Stormwater facilities.

i. Stormwater facilities for managing stormwater runoff from transportation facilities must meet all applicable Clean Water Services and City of Tigard standards.

ii. Above-ground vegetated water quality facilities are required wherever practicable.

iii. Water quality facilities may be located in an on-street parking lane in lieu of on-street parking or in the landscape strip or tree well area of the sidewalk corridor.

iv. Any stormwater facilities proposed in the public right-of-way are subject to approval by the City Engineer.

e. Pedestrian facilities.

i. Pedestrian facilities include sidewalks, trails, and paths. Definitions for these facilities are as follows:

•	Sidewalks are paved on-street transportation facilities for pedestrians.
•	Trails are paved off-street transportation facilities for pedestrians and bicyclists that span multiple developments, lots, or blocks. They are often located next to other linear corridors such as streams, highways, or rail lines and allow users to travel greater distances than paths.
•	Paths are paved off-street transportation facilities for pedestrians and bicyclists that provide connections through or between developments within a single block or for short distances.

ii. Sidewalks, trails, and paths must comply with the standards of this section and applicable federal and state accessibility requirements.

iii. Sidewalks, trails, and paths must generally be located within the public right-of-way. They may be located outside of the public right-of-way within a public access easement with approval by the City Engineer.

iv. Sidewalks must have a minimum unobstructed width of 6 feet for pedestrian through-travel, except for A-frame signs where the minimum unobstructed width is 4 feet. Any permanent structures or utilities within the required through-travel area are subject to approval by the City Engineer. Any sidewalk area outside of the required through-travel area may be used for commercial purposes by adjacent development or may contain pedestrian amenities, such as street furniture, bicycle parking, trash cans, and drinking fountains. Use of this area for commercial purposes includes, but is not limited to: customer seating, merchandise display, and A-frame signs. Use of this area for commercial purposes is at the sole discretion of the Director. A-frame signs are also subject to the standards and procedures in Chapter 18.435, Signs.

v. Trails must have a minimum right-of-way width of 15 feet and a minimum improved surface width of 10 feet. Trail widths may be reduced where constrained by existing development, protected natural resource areas, or topography as determined by the City Engineer.

vi. Paths must have a minimum right-of-way width of 12 feet and a minimum improved surface width of 8 feet. Path widths may be reduced where constrained by existing development, protected natural resource areas, or topography as determined by the City Engineer. Paths must be located to provide a reasonably direct connection between likely pedestrian destinations.

f. Bicycle facilities.

i. Bicycle facilities include bicycle parking, on-street shared lanes, on-street bike lanes (including buffered or protected bike lanes), trails, and paths. Trails and paths are defined in Subparagraph 18.660.090.C.4.e.i.

ii. Bicycle facility improvements include, but are not limited to: bicycle racks, signage, pavement markings, intersection treatments, traffic calming, and traffic diversion.

g. Transit facilities.

i. Transit facilities include transit stops, transit shelters, transfer stations, and other related public transit facilities.

ii. Transit facility improvements include, but are not limited to: benches, signage, shelters, bus turnouts, curb extensions, bicycle parking, pedestrian crossings, and pedestrian lighting.

iii. Factors that determine the level of transit improvements needed include, but are not limited to: street classification, existing and planned level of transit service on adjacent streets, block length, proximity of major pedestrian destinations, existing and estimated ridership, and estimated transit needs of the proposed development.

iv. Transit facilities must comply with current TriMet and city standards with final approval by the City Engineer.

D. Fee in lieu of construction (FILOC). If improvements to public transportation facilities are required by Subparagraph 18.660.040.B.2.b, the applicant may request to pay a fee in lieu of constructing the required improvements. The provisions of this Subsection do not allow the applicant to a pay a fee in lieu of dedicating any needed public right-of-way.

1. FILOC review criteria. The city may accept a fee in lieu of constructing the required improvements when one or more of the following conditions exist.

a. The city is actively in the process of studying or developing new design standards for one or more of the streets on which the proposed development has frontage.

b. Required improvements are not feasible due to the location of existing development or frontage improvements.

c. Required improvements are not feasible due to the inability to achieve proper design and safety standards.

d. Required improvements are part of a larger approved capital improvement project that is listed as a funded project in a local or regional Capital Improvement Program (CIP).

2. FILOC findings. If the City Engineer determines that a fee in lieu of construction satisfies one of the criteria in Paragraph 18.660.090.D.1, the city will accept a fee upon the City Engineer finding that deferring construction of required improvements will not result in any of the following.

a. Safety hazards as determined by the City Engineer.

b. New and significant street drainage issues as determined by the City Engineer.

If the City Engineer cannot make such findings, then the city will not accept a fee and will require construction of the required improvements.

3. FILOC fees. If the City Engineer determines that required improvements are eligible for FILOC, the applicant must pay the fee in lieu of constructing the required improvements unless the city determines that the fee is not roughly proportional to the number of new trips estimated to be generated by the proposed development. The City Engineer will determine the fee based upon an estimate to construct the required improvements using the average cost of the most recent capital improvement project itemized bid prices. The applicant must pay the fee to the city prior to the issuance of any development permits.

a. If full transportation facility improvements have been assessed with previous development on the site and the proposed development has additional impacts, the city may only assess additional FILOC fees when there has been a change to the city's street design standards.

b. If partial transportation facility improvements have been assessed with previous development on the site and the proposed development has additional impacts, the city may assess additional FILOC fees for the balance of the improvements.

c. If the applicant pays a fee in lieu of constructing the required improvements and is issued a development permit by the city but does not develop as planned, the applicant may request a refund of the FILOC fee within 3 years of payment. Any refunds are subject to the approval of the City Engineer.

4. FILOC program administration. Fees collected by the city will be used to construct public transportation facilities or to leverage additional grant money for larger transportation projects. An accounting of fees collected and expended will be made available by the city to the public on an annual basis at the end of the fiscal year. Expenditure of fees is subject to the following: Fees will be used for construction of public transportation facilities that benefit the development sites that paid the fees.
