f. 
Side Yard Appearance and Screening.
At least one of the following design treatments shall be applied along side yards or side elevations. This section is applicable to both interior side yards and side yards that abut streets.
i. 
Treatment 1 – Maximum Side Yard Plane.
(1) 
When the side elevation of a primary structure is more than 500 sq. ft. in area in an R-0, R-2, R-3, R-5, or R-6 zone ("Group 1") or more than 750 sq. ft. in area in an R-7.5, R-10, or R-15 zone ("Group 2"), the elevation must be divided into distinct planes of 500 sq. ft. or less for Group 1or 750 sq. ft. or less for Group 2. For the purpose of this standard, areas of side yard wall planes that are entirely separated from other wall planes are those that result in a change in plane, such as a recessed or projecting section of the structure that projects or recedes at least two ft. from the adjacent plane, for a length of at least six ft.
(2) 
Except in the R-0, R-2, R-3, and R-5 zones, the maximum side yard plane may be increased by 10% on a side for every additional five ft. of side yard setback provided beyond the minimum required by the zone, on the side property line.
ii. 
Treatment 2 – Side Yard Features.
(1) 
The side elevation of a structure shall consist of two or more planes that are offset by a minimum of 16 in. The wall planes shall be a minimum of four ft. in width, and shall result in a change in a wall plane for one full story.
Exception: Window bays may be utilized to satisfy the requirement for offsets. Such windows shall extend a minimum of 12 in. outward from the main wall of a building and shall form a functional bay or alcove in an interior room. Bay windows used to meet this requirement shall not be exempt from setback requirements.
(2) 
Walls shall include a roof eave overhang of 16 in. or greater, and
(3) 
Windows and/or doors shall occupy a minimum of 15% of the side elevation facing the street, and all windows shall have a window trim that is a minimum of four in. in width.
iii. 
Treatment 3 – Screening.
The applicant shall provide screening and buffering of the wall plane with a minimum of one standard plant unit for every 50 linear ft. of side building elevation or fraction thereof. Planting shall occur within an area that is defined by the length of the side elevation plus 20 ft. beyond the width of the building at either end, and outward 20 ft. from the side elevation of the building, towards the side lot line, as shown in Figure 50.06.001-H: Screening and Buffering.
Figure 50.06.001-H: Screening and Buffering

iii. 
On-Site Location of Required Parking Spaces.
(1) 
All required parking shall be off-street. Parking may not be located in a required yard or special street setback except where there are specific yard setback requirements or exceptions for parking established by the zone or use.
(2) 
Parking design shall ensure that the parking of any vehicle shall not interfere with the parking or maneuvering of any other vehicle.
Exceptions:
(a)
Residential Use: Tandem parking in residential developments is permitted if the tandem parking space is owned by, leased or assigned to a single residential owner or tenant.
(b)
FMU: In the FMU zone, tandem parking is permitted for a development if an attendant is present to move vehicles.
(c)
Commercial Uses Other Than in FMU Zone: Tandem parking is permitted for hotels or motels, eating or drinking establishments without drive-up window, clubs, lodges, meeting rooms, and auditoria in commercial zones if the following criteria are met:
 
(i)
An attendant is present to move vehicles and such movement of vehicles does not require backing onto a public right-of-way (an alley may be used if allowed by the City Engineer); or
 
(ii)
If the tandem parking is for the exclusive use of employees.
iv. 
Off-Street Parking Options.
(1) 
Off-Site Parking.
Within commercial, public use, industrial and campus institutional zones parking may be provided on remote lots within said zones which are within 500 ft. of the property line of the use to be served. Within the EC (East End General Commercial) zone only, unless otherwise prohibited, employee parking may be allowed within 1,000 ft. of the property line of the use to be served. Within the LGVCO only, unless otherwise prohibited, parking may be provided on remote lots within the District which are within 750 ft. (customer parking) and 1,000 ft. (employee parking) from the property line of the use to be served. If the remote parking lot is not owned by the owner of the property of the use to be served, said owner shall obtain an exclusive permanent easement in the remote lot so as to permit parking from the use to be served on the remote lot.
(2) 
Shared Parking.
(a) 
Except in the FMU zone, shared parking is allowed when a parking study demonstrates that there are a sufficient number (by actual or estimated count) of parking spaces to accommodate the parking needs generated by the applicant and other parking lot users during the applicant’s period(s) of use of the parking lot. A new parking study shall be submitted upon any one of the following events:
(i) 
Change from one type of use to another that has higher number of parking spaces required by Table 50.06.002-3 for the new use.
(ii) 
Where one use expands into the area of another use and it results in:
(A) 
A 10% or more increase in the number of parking spaces that would be required for the use under the Numerical Method, as if that method were applied to the use to determine the parking needs, rather than through a parking study; or
(B) 
For an "eating or drinking establishment" or a type of commercial amusement business, any increase in the number of parking spaces that would be required for the use under the Numerical Method, as if that method were applied to the use to determine the parking needs, rather than through a parking study.
(b) 
Parties involved in shared parking arrangements shall enter into reciprocal agreements, acceptable to the City for such use, by legal instrument which shall also provide for continuing maintenance of jointly used parking facilities.
v. 
Reduction for Parking Space Requirements.
(1) 
Parking space requirements shall be reduced in developments where compensating factors exist which would offset the parking demand (such as access to transit facilities, pedestrian and bicycle access, development size, or combined, or the parking study provision). Refer to Table 50.06.002-4 for reduction options.

ii. 
Driveway approaches in the right-of-way shall be constructed according to the City’s Standard Details.
iii. 
In locations where there is a slope adjacent to a driveway edge, there shall be a minimum two ft. shoulder or other means of protecting the driveway and the adjacent land from the adverse effects of erosion.
iv. 
Stormwater running off a driveway shall be managed and disposed of in compliance with the applicable drainage standards for minor or major development, and the Uniform Plumbing Code.
v. 
Where a driveway approach needs to cross a roadside ditch, a culvert of ten in. minimum diameter shall be used. The City may require a larger culvert if warranted by the hydrology of the upstream drainage basin.
vi. 
All driveways shall be paved with a material that does not generate dust. Hard pavement is required except in the following circumstances:
(1) 
Low-use driveways, such as one serving a parking area for recreational vehicles, boat trailers, or access to a storage building or storage area.
(2) 
Where a driveway grade changes less than 10% from the street to the parking area serving a single-family residence or duplex.
(3) 
Existing unpaved driveways, when there is an existing use on the site that is rated at ten or less average daily trips per weekday pursuant to the applicable ITE (Institute of Transportation Engineers) category, and the rating will not be increased with the proposed development.
(4) 
When the requirement for a paved driveway is waived, a paved approach shall be constructed to prevent the tracking of loose gravel onto the public street.
(5) 
Temporary construction access driveways.
(6)

a. 
Applicability.
This section is applicable to all subdivisions and to all minor and major development involving the construction of a new structure other than a detached single-family dwelling, middle housing dwelling, or accessory structures. This section is also applicable to modifications which increase the square footage of commercial, industrial, public use or institutional buildings by more than ten percent. For the purposes of this section, an "existing building" is a building as it exists on February 19, 1998.
b. 
Standards for Approval.
FMU Standards Note: If the below provisions address the same subject as provided in the Foothills Building and Site Design Standards, LOC § 50.11.007, Appendix G, those standards shall supersede the below provisions.
i. 
Commercial, industrial, public use, and institutional developments of one acre or more shall provide a pedestrian circulation plan for the site.
(1) 
Pedestrian connections between the proposed development and existing development on adjacent properties other than connections via the street system shall be identified and implemented, where feasible.
ii.

Walkways shall also connect to other areas of the site, such as parking lots and outdoor activity areas, to other building entrances, to adjacent streets and nearby transit stops.
iii. 
Walkways shall meet accessibility standards of the Americans with Disabilities Act (ADA) and standards as found in the Oregon State Structural Specialty Code, Section 1103, if applicable. Walkways within the site, connections to the public sidewalk, and external connections off site shall provide convenient, accessible, and the most practical direct, barrier-free route design.
iv. 
Portions of walkways shorter than 30 ft. across driveways, parking lots or walkways crossing surfaces shared by fork lift or heavy truck traffic may use a painted crossing zone. Otherwise, walkways crossing driveways, parking areas, and loading areas shall be clearly identifiable through the use of a different paving material, raised elevation, or other similar method.
(1) 
Where walkways are adjacent to vehicle travel areas, they shall be separated by a raised curb, bollards, buttons, landscaping or other physical barrier. If a raised walkway is used, the ends of the raised portions shall be equipped with curb ramps.
v. 
Accessways for use by pedestrians and bicyclists shall be required when necessary to provide direct routes not otherwise provided by the existing right-of-way. Developments shall not be required to provide right-of-way for accessways off site to meet this requirement. If right-of-way is otherwise available off site, the developer may be required to improve an accessway off site to the nearest transit route.
c. 
Standards for Construction.
FMU Standards Note: If the below provisions address the same subject as provided in the Foothills Building and Site Design Standards, LOC § 50.11.007, Appendix G, those standards shall supersede the below provisions.
i. 
The surfacing of walkways, bikeways and accessways shall consist of either two in. of asphaltic concrete over a minimum of four in. of compacted crushed rock, or of four in. of concrete, as determined by the City Manager. Other materials must be specifically approved by the City Manager.
ii. 
Walkway surfacing shall be five ft. in unobstructed width, unless specifically otherwise approved by the City Manager, and never less than four ft. in unobstructed width.
iii. 
Walkways without stairs shall have a maximum cross slope of 2% and a maximum slope of 8%. If the existing grade exceeds an 8% slope and the walkway construction requires an erosion control permit pursuant to LOC § 52.02.040.1, and construction of stairs is impracticable, then the pathway may follow the existing grade.
iv. 
Ramps for handicapped use are required on all walkways used by the public at all points where a path intersects a curb.
v. 
Walkways, bikeways and accessways must be constructed in such a way as to allow the surface drainage to sheet flow across them, and not flow along them longitudinally.
vi. 
An accessway shall include at least a 15-ft. wide right-of-way or easement and an eight-ft. wide hard surface. For safety, accessways shall be as straight as practicable. Bollards, buttons, or landscaping shall be used to block motor vehicular access.
vii. 
A residential accessway shall include at least a 15-ft. wide right-of-way or easement and a minimum six-ft. wide travel surface. Accessways may meander around major trees or vegetation, but shall be as straight as practicable, considering the circumstances related to the property.
viii. 
The surfacing of residential accessways shall consist of either two in. of asphaltic concrete over a minimum of four in. of compacted crushed rock, or four in. of concrete, as determined by the City Manager. Depending on location, topography or presence of sensitive lands, other materials may be specifically approved by the City Manager.

Street Connectivity.
[Ord. No. 2579, Repealed and Replaced, 3-20-2012; Ord. No. 2599, Amended, 12-18-2012; Ord. No. 2612-A, Amended, 5-21-2013; Ord. No. 2687, Amended, 12-15-2015; Ord. No. 2725, Amended, 12-6-2016; Ord. No. 2760, Amended, 12-5-2017; Ord. No. 2797, Amended, 11-6-2018; Ord. No. 2832, Amended, 1-7-2020; Ord. No. 2892, Amended, 6-7-2022]
a. 
Applicability.
This section is applicable to:
i. 
Any development that results in the construction of a street; or
ii. 
A land division that:
(1) 
Is located on a parcel or parcels of vacant or redevelopable land of 1.75 acres or more, or
(2) 
Abuts a parcel upon which there is a street that has been "stubbed" to the proposed development site.
iii. 
Construction of a detached single-family dwelling, middle housing dwelling, multi-family dwelling, commercial, industrial, institutional, or public function structure that:
(1) 
Is located on a parcel or parcels of vacant or redevelopable land of 1.75 acres or more, or
(2) 
Abuts a parcel upon which there is a street that has been "stubbed" to the proposed development site.
This section is not applicable to development or construction in the FMU zone.
b. 
Purpose and Intent.
The purpose of the connectivity standard is to ensure that:
i. 
The layout of the street system does not create excessive travel lengths or limit route choices. This will be accomplished through an interconnected street system to reduce travel distance, promote the use of alternative modes of travel, provide for efficient provision of utility and emergency services, provide for more even dispersal of traffic, and reduce air pollution and energy consumption;
ii. 
Streets, alleys and residential accessways shall be designed to meet the needs of pedestrians and cyclists and encourage walking, bicycling and transit as transportation modes;
iii. 
Street and pedestrian and bicycle accessway design is responsive to topography and other natural features and avoids or minimizes impacts to LOC § 50.05.010, Sensitive Lands Overlay Districts; LOC § 50.05.011, Flood Management Area; and steep slopes pursuant to LOC § 50.06.006.2, Hillside Protection;
iv. 
Circulation systems and land development patterns do not detract from the efficiency of the adjacent collector or arterial streets;
v. 
The street and accessway circulation pattern contributes to connectivity to and from activity centers, such as schools, commercial areas, parks, employment centers and other major trip generators;
vi. 
Metro Regional Transportation Function Plan, Title 1, street connectivity requirements are met;
vii. 
Proposed development will be designed in a manner which will not preclude properties within the vicinity that meet the definition of further developable, from meeting the requirements of this standard; and
viii. 
Transportation connections improve access to schools, transit, shopping, and employment areas.
c. 
Standards for Approval of Development Which Requires the Construction of a Street.
i. 
Local and neighborhood collector streets, access lanes, and residential accessways shall be designed to connect to the existing transportation system to meet the requirements of this standard as determined by the reviewing authority.
ii. 
Local and neighborhood collector street design shall provide for full street connections between through streets with spacing of no more than 530 ft., measured between the center of the intersection of two through streets that provide for vehicle traffic movement in generally the same direction ("through street pairs") with the cross street. This requirement shall be applied to all through street pairs which surround the site. If the nearest boundary of the site (or boundaries extended to the street) is more than 100 ft. from the intersection of a through street nearest to the site and the cross street, the provisions of this standard shall be met, except when the provisions of subsection 4.c.vi of this section are met. See Figure 50.06.003-A: Street Connectivity.
Figure 50.06.003-A: Street Connectivity
LU--Image-150.tif
iii. 
Streets shall be designed to connect to all existing or approved stub streets which abut the development site.
iv. 
Cul-de-sacs and permanent closed-end streets shall be prohibited except where (a) the requirements of this standard for street and residential accessway spacing are met and (b) construction of a through street is found to be impracticable. When cul-de-sacs or closed-end streets are allowed under subsection 4.c.vi of this section, they shall be limited to 200 ft. and shall serve no more than 25 dwellings, except where the reviewing authority has determined that this standard is impracticable due to the criteria listed in subsection 4.c.vi of this section.
v. 
Access lanes may be used to serve up to three lots.
vi. 
The reviewing authority may allow an exception to the review standards of subsections 4.c.i through 4.c.v of this section based on findings that the modification is the minimum necessary to address the constraint and the application of the standards is impracticable due to the following:
(1) 
Extreme topography (over 15% slope) in the longitudinal direction of a projected automobile route;
(2) 
The presence of Sensitive Lands as described in LOC § 50.05.010, or LOC § 50.05.011, Flood Management Area, or other lands protected by City ordinances, where regulations discourage construction of or prescribe different standards for street facilities, unless the nearest through street pairs (see Figure 50.06.003-A: Street Connectivity) surrounding the subject site are more than one-quarter mile apart. The reviewing authority may determine that connectivity is not required under this circumstance, if a benefit/cost analysis shows that the traffic impacts from development are low and do not provide reasonable justification for the estimated costs of a full or limited access street connection;
(3) 
The presence of freeways, existing development patterns on abutting property which preclude the logical connection of streets or arterial access restrictions;
(4) 
Where requiring a particular location of a road would result in violation of other City standards, or state or county laws or standards, or a traffic safety issue that cannot be resolved;
(5) 
Where requiring streets (full or limited access) or accessways would violate provisions of leases, easements, covenants, restrictions or other agreements existing as of May 1, 1995, which preclude required street or accessway connections; or
(6) 
Where there is minimal public benefit of improved vehicular access and circulation, a limited access street connection (in lieu of a full street connection) may be approved provided it does not preclude development of adjacent property and is consistent with the purpose and intent in LOC § 50.06.003.4.b. For determining public benefit, the travel needs of existing, proposed and potential future development and emergency vehicle access needs shall be considered. Limited access streets shall conform to the spacing standards in subsection 4.c.vii of this section.
vii. 
If the reviewing authority allows an exception to subsection 4.c.ii of this section for full street connections, it shall require residential accessway connections on public easements or rights-of-way so that spacing between bicycle and pedestrian connections shall be no more than 330 ft. measured from the centerline of the nearest bicycle and pedestrian connection intersection with the cross street.
viii. 
The reviewing authority may allow a reduction in the number of residential accessway connections required by subsection 4.c.vii of this section based on findings that demonstrate:
(1) 
That reducing the number or location of connections would not significantly add to travel time or distance from the proposed development to bus lines or activity centers in the area, such as schools, shopping, or parks; or
(2) 
That existing development patterns on abutting properties preclude logical connection of residential accessways; or
(3) 
That the traffic impacts from development, redevelopment or both are low and do not provide reasonable justification for the estimated costs of such accessway.
[Cross-Reference: Subsection 4.c.iv – see also LOC § 42.03.085.]
d. 
Standards for Approval for a Land Division or Development That Does Not Require Construction of a Street.
The review authority shall require:
i. 
A future connectivity plan to be filed with the City and recorded in the applicable County Clerk records. The future connectivity plan shall show how the location of future streets, access lanes, and accessways will provide for full development of the subject parcel as well as any abutting properties in order to meet the standards of LOC § 50.06.003.4.c.ii through viii; and
ii. 
Placement of structures in a manner that allows for the future street(s), access lanes, or accessways to be constructed, as well as an area sufficient to meet the required zone setbacks from the future streets.
e. 
Standards for Construction.
i. 
Standards for construction of full street and limited access street connections shall be those included in LOC Chapter 42. Where emergency vehicle access is required on limited access streets, the limited access street shall be 16 ft. in width, contain removable bollards where it adjoins other streets, and consist of a driving surface that accommodates emergency vehicle apparatus as approved by the City Engineer.
ii. 
Standards for construction of access lanes shall be those included in LOC § 50.06.003.1.d, Standards for Access Lanes.
iii. 
Standards for construction of residential accessways shall be those included in LOC § 50.06.003.3.c.
iv. 
Where a temporary street-end is created, it shall be stubbed to the property line with posted notification identifying it as temporary and planned for future extension.
[Cross-Reference: See LOC § 50.07.003.1.a.iii.]
5.

Standards for Approval.
All applicable development as defined above shall be required to provide transit facilities and transit-oriented features.
i. 
The extent of the transit-oriented features and transit facilities required for a particular site on a transit street shall be determined by the City, in coordination with Tri-Met, based upon an analysis of:
(1) 
Level of existing and projected adjacent transit facilities;
(2) 
Proximity of other ridership attractors, such as bus routes;
(3) 
Size and trip generation potential of proposed development adjacent to transit street (within one-fourth mile of a transit street); and
(4) 
Expected transit ridership generated by a development.
ii. 
Transit-oriented features for a site within one-fourth mile of a transit street shall be provided to connect the development with:
(1) 
The nearest adjacent transit street; or
(2) 
Adjacent paths which lead to the nearest transit street.
iii. 
Where a proposed development creates or contributes to a need for transit stops, pullouts, or other transit facilities, as identified by the City in coordination with Tri-Met, easements or right-of-way dedication may be required.

Minor or major development that results in increased use of public and private streets, public pathways and accessways, or open air parking lots;
ii. 
Addition, removal, alteration, or expansion of light fixtures or poles in open air parking lots or public pathways or accessways; or
iii. 
Addition, removal, alteration, or expansion of outdoor lighting on lots in PF and PNA zones.
Exception: Temporary lighting for theatrical, television, and performance areas, and lights associated with special events are not subject to this section if no development occurs.
b. 
Standards for Approval.
i. 
Public Pathways and Accessways.
Low level lighting of less than 0.3 average foot-candles and with a maximum uniformity of illuminating ratio not to exceed 20:1 shall be required in all zones, except the PF and PNA zones, unless the applicant can show that no night use of such facilities is planned.
ii. 
Open Air Parking Lots.
The following standards shall apply to open air parking lots in all zones, except the PF and PNA zones:
(1) 
General Provisions.
(a) 
For multi-level parking facilities, the roof level shall be considered an open air parking lot.
(b) 
Open air parking lot lighting shall be designed to provide uniform lighting throughout the facility, but shall accomplish uniform lighting with the minimum lighting necessary for safety, security, and identification of necessary features.
(c) 
Open air parking lot lighting shall not produce light trespass by the direct illumination of adjacent and nearby properties or streets.
(d) 
Open air parking lot lighting shall not produce annoying or disabling glare at normal viewing angles.
(e) 
Where an open air parking lot is not anticipated to have a nighttime use, or where lighting would be out of character with the immediate environment, the reviewing authority may waive the illumination requirement.
(2) 
Equipment and Installation Standards.
(a) 
Open air parking lot lighting shall employ the use of full cut-off fixtures as defined by the Illuminating Engineering Society of North America (IESNA), except in special design districts where a particular "period" or architectural style has been adopted, or as specifically allowed by the reviewing authority.

ii. 
Applicants shall be encouraged to design and site a proposed habitable structure so that the lowest height of the solar feature(s) will not be shaded by buildings or solar-unfriendly trees on lot(s) to the south. The applicant shall complete the following calculation procedure to determine if the solar feature(s) of the proposed structure will be shaded. To start, the applicant shall choose which of the following sources of shade originating from adjacent lot(s) to the south to use to calculate the maximum shade height at the north property line:
(1) 
Existing structure(s) or solar-unfriendly trees; or
(2) 
The maximum shade that can be cast from future buildings or solar-unfriendly trees, based on Table 50.06.007-3. If the lot(s) to the south can be further divided, then the north-south dimension shall be assumed to be the minimum lot width required for a new lot in that zone.

Streets, sidewalks (pathways), curb and gutters or other street improvements (e.g., gravel shoulders, drainage swales).
(6) 
Additional public infrastructure.
ii. 
Additional Street Right-of-Way Dedication Requirements.
If existing rights-of-way for streets contiguous to the property are not adequate in width to meet the referenced standards in subsection 3.b.i of this section, the applicant shall dedicate right-of-way sufficient to allow streets that are adequate in width and that connect to existing public streets and sidewalks/pathways and related public infrastructure.
Dedication of the minimum right-of-way is that required for the minimum width necessary as provided in the referenced plans and specifications in subsection 3.b.i of this section for streets where the City is the road authority. For streets where another governmental entity is responsible for the design and construction standards of a street, e.g., road authority per ORS 810.010 or county authority over county roads per ORS 368.016, then dedication to the minimum width is that required by the applicable governmental standards.
Urbanizing Rural Fringe and Transition Neighborhoods[1]
LU--Image-151.tif
[1]
Editor’s Note: The Engineering Department’s Urbanizing Rural Fringe and Transition Neighborhoods Policy is presently applicable to the area shown below, except for streets where the county is the road authority.
iii. 
Street Paving.
Streets shall be designed and pavement installed from the continuation of the roadway centerline out to the applicable stated distance as provided in the relevant plans and specifications.
e. 
City Engineer Reduction or Elimination.
The City Engineer may reduce or eliminate the specific utilities, streets/sidewalks or other public infrastructure requirements of this subsection 3 upon a finding that:
i. 
Existing infrastructure meets the standard;
ii. 
It is not the appropriate time to connect the required utilities, streets/sidewalks or other public infrastructure with other nearby utilities, streets/sidewalks or other public infrastructure. In that event, the owner shall execute and record a covenant that the owner shall construct the specific utilities, streets/sidewalks or other public infrastructure upon notice by the City Manager, or if permitted by the City Manager, in lieu of a covenant, the owner shall execute a waiver of remonstrance for the formation of a local improvement district for said utilities, streets/sidewalks or other public infrastructure; or
iii. 
The required utilities, streets/sidewalks (pathways) and other public infrastructure must be reduced because the requirement would exceed the rough proportionality legally permissible, considering the factors listed in subsection 7.b of this section, to the extent stated in subsection 7.c of this section.
4. 
Standards for Construction.
[Ord. No. 2579, Repealed and Replaced, 3-20-2012; Ord. No. 2797, Amended, 11-6-2018; Ord. No. 2853, Amended, 2020; Ord. No. 2908, Amended, 6-6-2023; Ord. No. 2909, Amended, 2-7-2023]
a. 
Utility construction within easements shall minimize disturbance to existing conditions, especially trees and other vegetation.
b. 
Any disturbed areas within easements shall be restored to a condition similar to the condition prior to construction, including the replacement of plants of similar species as those removed or damaged. Replacement trees shall be of similar species and be a minimum of one and one-half in. caliper.
c. 
Utilities to the development and existing utilities along the development’s street frontage shall be installed underground unless exempted by the City Manager for any of the following reasons:
i. 
Developments which need multiphase voltages or high kilo volt amperes (kVA) demands may develop with pad transformers where underground transformers are not feasible. Padmounted transformers shall be buffered from sight by landscaping or other suitable methods.
ii. 
Pad-mounted transformers are allowed in subdivisions, but shall be buffered from sight by landscaping or other suitable methods.
iii. 
Above ground telephone and cable television junction boxes are allowed.
iv. 
Accessory Dwelling Units (ADUs). No undergrounding of existing or new utilities along street frontages is required. Undergrounding of new on-site utilities is required for ADUs that add floor area.
v. 
Remodel of Structures. No undergrounding of existing or new utilities along street frontages is required. Undergrounding of new on-site utilities is required for building additions that add floor area.
vi. 
Land Division in Residential Zone. If the parcel of land that is the subject of a land division ("parent parcel") is less than four times the minimum lot area for the residential zone (regardless of the actual number of lots created by the land division), existing utilities along the street frontage are exempt, but new utilities to development within the area of the parent parcel shall be installed underground.
vii. 
Deferred Undergrounding. Any requirement to underground existing utilities along the street frontage ("street frontage" applies to both sides of a street) of a development may be deferred by the City Manager upon finding that undergrounding of utilities is not practicable at the time. In lieu of then undergrounding, the owner shall execute a covenant, approved by the City Attorney, and recorded in the official records of the county where the real property is located, binding upon the lots created by the land division of the parent parcel in any zone, and any later land divisions of those lots:
(1) 
Waiving the right to remonstrate regarding the formation of a local improvement district to underground utilities; and
(2) 
Obligating the owner(s) to underground existing utilities along the frontage of the parent parcel when the City Manager determines that it is practicable to underground the frontage utilities. The covenant shall provide that the cost of undergrounding is a joint and several obligation of the owner(s), and shall provide for the right of any owner to perform the undergrounding and to lien the other properties for the cost. If the owner(s) fail to perform the undergrounding as required, the City shall have the right to undertake the undergrounding and to lien all properties jointly and severally for the cost of the undergrounding, including an additional 20% for administrative cost.
d. 
Sanitary Sewers.
Capacity, grade and materials shall be as approved by the City Manager. Minimum size shall be eight in. diameter with six in. diameter allowed at the terminus of a sewer line.
e. 
Service Laterals.
One service lateral shall be provided to each lot.
f. 
All facilities as described in this section shall be constructed in compliance with the rules and regulations of the City Manager.
5. 
Standards for Maintenance.
[Ord. No. 2579, Repealed and Replaced, 3-20-2012; Ord. No. 2908, Amended, 6-6-2023]
None.
6. 
Cost of Improvements.
[Ord. No. 2579, Repealed and Replaced, 3-20-2012; Ord. No. 2908, Amended, 6-6-2023]
The cost of all utility, street/sidewalks (pathway) and other public infrastructure improvements shall be borne by the developer.
[Cross-Reference: See also LOC Chapter 39 – System Development Charges.]
7. 
Limitation to Requirement to Design and Install Required Utilities; Streets/Sidewalks (Pathways) and Other Public Infrastructure.
[Ord. No. 2908, Added, 6-6-2023]
a. 
Application for Limitation.
If the applicant asserts that the required utilities, streets/sidewalks (pathways) and other public infrastructure cannot legally be required, as a requirement or condition of structural permit or development review approval, to provide dedications or improvements at the level otherwise required by this section, then the applicant shall file a minor development application to seek a limitation on the requirement for installation of utilities, streets/sidewalks (pathways) and other public infrastructure;
b. 
Rough Proportionality Report.
In addition to the requirements for a minor development application per LOC § 50.07.003.1 and .14, the structural permit or development review application shall include a rough proportionality report, prepared by a qualified civil or traffic engineer, as appropriate, showing:
i. 
The estimated extent, on a quantitative basis, to which the improvements will be used by persons served by the building or development, whether the use is for safety or for convenience;
ii. 
The estimated level, on a quantitative basis, of improvements needed to meet the estimated extent of use by persons served by the building or development;
iii. 
The estimated impact, on a quantitative basis, of the building or development on the public infrastructure system of which the improvements will be a part;
iv. 
The estimated level, on a quantitative basis, of improvements needed to mitigate the estimated impact on the public infrastructure system; and
c. 
Amount of Limitation.
If the reviewing authority concludes that the required utilities, streets/sidewalks (pathways) and other public infrastructure must be limited because the requirement would exceed the rough proportionality legally permissible, the applicant shall, instead, be required to provide dedications and improvements on site or off site that are roughly proportional to what is needed to mitigate the impacts of the building, structure or development upon the public infrastructure system, and for the convenience of persons served by the building, structure, or development.
1. 
Scope and Compliance.
[Ord. No. 2579, Repealed and Replaced, 3-20-2012; Ord. No. 2668, Amended, 12-1-2015; Ord. No. 2841, Amended, 9-1-2020]
a. 
No landmark or contributing resource or part thereof shall be demolished, moved, or altered, nor shall any major or minor development take place within a Historic District or involving a landmark nor shall a land division or lot line adjustment of any landmark take place, except in conformity with the requirements of this section. No alterations to noncontributing resources shall be made except in conformity with the requirements of this section.
b. 
In addition, per OAR 660-23-0200, no structure or site listed on the National Register of Historic Places shall be demolished, relocated, or altered except in compliance with this section.
c. 
Archaeological resources shall be protected and preserved per subsection 10 of this section.
2. 
Exemptions.
[Ord. No. 2579, Repealed and Replaced, 3-20-2012; Ord. No. 2841, Amended, 9-1-2020]
The following actions are exempt from the provisions of this section:
a. 
The demolition, moving, or alteration of noncontributing resources;
b. 
Water quality protection actions;
c. 
Maintenance or repair that does not involve a change in design, materials, or appearance;
d. 
Alterations, demolitions, or relocations determined by the City Manager to be necessary to proceed without delay in order to preserve the public safety and convenience due to the presence of an unsafe, dangerous, or emergency condition;
e. 
Interior alterations; and
f. 
Development relating to a National Register property that is not on the Local Landmark List and that does not constitute demolition (as defined by subsection 9.b of this section) or relocation.
3. 
Cultural Resources Inventory.
[Ord. No. 2841, Added, 9-1-2020]
a. 
Purpose of Cultural Resource Inventory (CRI).
The CRI consists of surveys of examined structures and/or sites. It is used as a resource document in determining whether the structure or site meets the criteria for historic designation.
b. 
Content of CRI Survey of Property or Site.
The CRI survey shall describe the historic name, ownership, location and setting, age, use, architectural style, design elements, alterations/additions, significant landscape features, and statement of historic significance of the property or site. The survey shall comply with the State Historic Preservation Office "Guidelines for Historic Resource Surveys in Oregon." Current photographs or archival documentation for properties already listed in the Landmark Designation List or National Register may be included. The survey shall classify the property or site as Eligible/Significant (ES), Eligible/Contributing (EC), Non-Contributing (NC), or Not in Period (NP).
c. 
Effect of Inclusion in CRI.
Inclusion of property or sites in the CRI does not mean that the property or site is automatically eligible for historic designation and placement on the Landmark Designation List, and property or sites not included in the CRI may also be considered for historic designation. The property or site included in the CRI must be later reviewed to determine if it qualifies as a landmark under the Criteria for Designation (subsection 4 of this section).
d. 
Acceptance of CRI Survey of Property or Site.
When the City Manager surveys properties or sites for inclusion in the CRI, the owner shall be notified by mail not less than 10 days prior to conducting the survey. Within six months of the City Manager’s completion of the draft survey, it shall be submitted to HRAB for review and acceptance. The review shall be held at a public meeting and interested persons may comment and supplement the survey. HRAB’s review shall be for accuracy and acceptance of the survey with any appropriate corrections or additions.
4. 
Designation and Removal of Designation.
[Ord. No. 2579, Repealed and Replaced, 3-20-2012; Ord. No. 2841, Amended, 9-1-2020]
a. 
Criteria for Designation of a Landmark.
i. 
In order to designate a site, object or structure as a landmark, the Historic Resources Advisory Board (HRAB) shall find that the owner has, pursuant to ORS 197.772(1), consented to the proposed designation; and
(1) 
The resource is nominated to be placed on the National Register of Historic Places; or
(2) 
The resource is 50 years old or older and the resource has historical or architectural significance to Lake Oswego; or
(3) 
The resource is less than 50 years of age but of exceptional historic or architectural significance.
ii. 
HRAB shall consider the following factors in determining whether the criteria found in subsection 4.a.i(2) or (3) of this section are satisfied:
(1) 
Historical Significance.
(a) 
Significant association with the lives, events or activities of a person(s), group, organization, or institution, which at the time, made a significant contribution to local (Lake Oswego), regional, state, or national history;
(b) 
A birthplace or grave site of a historical figure of outstanding importance if there is no building standing that is directly associated with the activities for which the figure is celebrated;
(c) 
A high likelihood that, if preserved, would yield important information on the local area’s prehistory or history; or
(d) 
Significance because the resource contributes to the continuity or historic character of the local (Lake Oswego) area, region, state, or nation.
(2) 
Architectural Significance.
(a) 
Distinctive characteristics of a type, period, or method of construction, or represents the work of a master (outstanding work of a designer, builder, or architect who has made a substantial contribution to the field), or possesses high artistic values, or represents a significant and distinguishable entity whose components may lack individual distinction;
(b) 
Significance because the resource retains its original design features, materials, and/or character;
(c) 
Significance as the only remaining, or one of the few remaining, resources of a particular style, building type, design, material, or method of construction;
(d) 
Is a historic resource removed from its original location but which is significant for its architectural value; or
(e) 
Is a creative and unique example of folk architecture and design created by persons not formally trained in the architectural or design professions and which does not fit into formal architectural or historical categories.
The considerations listed in this section are not standards for approval and are not intended to be an exclusive list of considerations. The considerations are to be used as a guide in the granting authority’s deliberations.
b. 
Criteria for Designation of a Historic District.
i. 
In order to designate a geographic area as a Historic District, HRAB shall find that:
(1) 
A majority of the parcels contain structures that are designated as landmarks or contributing resources; and
(2) 
A perceptible common theme, which is either of historic or architectural significance, unifies the area.
ii. 
HRAB shall consider the following factors in determining whether the criteria found in subsection 4.b.i of this section are satisfied:
(1) 
The district size is large enough to create a visual identity;
(2) 
A majority of parcels contain structures eligible for landmark or contributing resource designations;
(3) 
The prevalence of other historic or environmental features in the area such as mature landscaping, original street layout, stone fences, etc;
(4) 
Perceptible common theme;
(5) 
Sites, objects, structures and buildings contribute to the integrity of the district’s theme;
(6) 
More than one theme may exist; however, a dominant theme or common element among themes establishes the district identity. An example of a common theme could be a period of time or development phase in the City’s growth.
The factors listed in subsection 4.b.ii of this section are not standards and are not intended to be an exclusive list of considerations, but are intended to be used as a guide in the granting authority’s deliberations.
iii. 
In order to approve expansion of the boundaries of a Historic District, HRAB shall consider the proposed expansion area with the existing district, and then determine whether the designation criteria found in subsection 4.b.i of this section are satisfied for the entire new district after the proposed expansion is added.
c. 
Criteria for Designation of a Contributing Resource.
i. 
In order to designate a site, object, or structure as a contributing resource, HRAB shall find that:
(1) 
The resource is or, at the time the designation becomes effective, will be within a Historic District; and
(2) 
The resource is 50 years old or older, may have received alterations, but retains its overall physical integrity; and
(3) 
The resource contributes to the integrity of the Historic District; and
(4) 
The resource does not merit a landmark designation; and
(5) 
The resource is compatible with landmarks in the district considering overall proportions, scale, architectural detail and materials.
ii. 
Contributing resources shall be identified upon the creation of a Historic District and a list shall be created containing the same information for each resource as is required for landmarks in subsection 5 of this section and shall be maintained in Table 50.06.009-1 under a separate heading for each Historic District.
d. 
Criteria to Remove a Designation.
i. 
In order to remove a landmark designation HRAB shall find either:
(1) 
The landmark designation is no longer justified after consideration of the criteria found in subsection 4.a of this section, Criteria for Designation of a Landmark; and through an ESEE analysis the benefits of removing the designation of the proposed landmark outweigh the benefits of continuing the designation; or
(2) 
The Building Official declares that the locally significant historic resource poses a clear and immediate hazard to public safety and must be demolished to abate the unsafe condition; or
(3) 
Per ORS 197.772(3), the designation was imposed on the property and the owner at the time of designation:
(a) 
Has retained ownership since the time of designation; and
(b) 
Can demonstrate that the owner objected to the designation on the public record or was not provided an opportunity to object to the designation; and
(c) 
Requests that the HRAB remove the resource from the inventory.
ii. 
In order to approve reduction of a Historic District boundary or abolish a district HRAB shall find that the district or its configuration is no longer justified after consideration of the criteria found in subsection 4.b of this section.
iii. 
In order to remove a contributing resource designation HRAB shall find that the contributing resource designation is no longer justified after consideration of the criteria found in subsection 4.c of this section.
5. 
Adoption of Landmark Designation List.
[Ord. No. 2579, Repealed and Replaced, 3-20-2012; Ord. No. 2841, Amended, 9-1-2020]
a. 
Adoption of Landmark Designation List.
The sites, structures and objects listed in the Landmark Designation List, Table 50.06.009-1, are subject to the provisions of this section.
b. 
Landmark Designation List.
The buildings, sites, structures, and objects listed below are designated as a Historic Landmark unless removed pursuant to LOC § 50.07.002.5 and Table 50.07.001-1. (The City Recorder may revise the list upon final designation or removal decision.) The findings of fact regarding the historical and architectural significance of the historic resource for its designation or removal for each property on the Landmark Designation List are on file with the Planning Department.

Moving or Demolition of a Landmark or Contributing Resource.
[Ord. No. 2579, Repealed and Replaced, 3-20-2012; Ord. No. 2841, Amended, 9-1-2020]
a. 
Criteria for Moving a Landmark.
i. 
In order to allow the moving of a landmark HRAB shall find that:
(1) 
The proposed relocation site will not greatly reduce the historical or architectural significance of the landmark; and
(2) 
Relocation is the only alternative for preservation of the landmark; and
(3) 
Through an ESEE analysis the proposed new development provides a greater community benefit than keeping the landmark on its present site; and
(4) 
If the landmark is to be relocated within the City of Lake Oswego, the owner of the relocation site agrees, as a condition of the purchase agreement, to apply within 90 days of relocation to the City for protection of the landmark at its new location.
ii. 
HRAB shall consider the following factors in determining whether the criteria found in subsection 6.a.i of this section are satisfied:
(1) 
The designated resource cannot reasonably be used in conjunction with the proposed use.
(2) 
The continued location of the landmark on a proposed development site precludes development on the site which would provide a greater community benefit.
(3) 
The designated landmark is structurally capable of relocation.
(4) 
The proposed relocation site is a contextually appropriate setting for the designated landmark.
(5) 
The proposed relocation site is within the City limits or preferably within the neighborhood where it is currently located.
b. 
Criteria for Demolition of a Landmark.
i. 
In order to allow the demolition of a landmark, the HRAB shall find that:
(1) 
The landmark is a severe hazard to public health or safety; or
(2) 
Through an Economic Social Environmental and Energy (ESEE) analysis, that the benefits of demolishing the landmark and the construction of the conflicting use outweigh the benefits of preserving the landmark, and that there are no alternatives to demolishing the landmark; or
(3) 
A denial of the request will deny the property owner reasonable economic use of the property; and
(4) 
The applicant completed a viable site development plan for the site including plans approved, if applicable, by the Building Official.
ii. 
HRAB shall consider the following factors in determining whether the criteria found in subsection 6.b.i of this section are satisfied:
(1) 
The significance of the landmark;
(2) 
If within a Historic District, the landmark’s contribution to the district and the effect on the integrity of the district if the landmark is demolished;
(3) 
Existing City plans, policies or City Council actions that identify community benefit in either preserving or demolishing the landmark;
(4) 
The physical condition of the resource.
The findings of fact regarding the historical or architectural significance for the designation of the landmark shall be used as the primary factual basis upon which decisions are based concerning the historical or architectural significance of the landmark.
c. 
Balancing of Competing and Conflicting Interests.
A determination of whether the criteria set forth in subsection 6.a.i or 6.b.i of this section are satisfied necessarily involves the balancing of competing and conflicting interests.
The factors listed in subsection 6.a.ii or 6.b.ii of this section are not standards for approval and are not intended to be an exclusive list. The factors are to be used as a guide in HRAB’s consideration.
d. 
Conditions of Approval of Demolition Permit.
As a condition of approval of a demolition permit, HRAB shall:
i. 
Require photographic documentation, preparation of architectural drawings, and other graphic data or history as it deems necessary to preserve an accurate record of the resource. The historical documentation materials shall be the property of the City or other party determined appropriate by HRAB.
ii. 
Require that the property owner document that a qualified local preservation group has been given the opportunity to salvage and/or record the resource.
e. 
Criteria of Approval of Moving or Demolition of a Contributing Resource.
In order to allow the demolition or moving of a contributing resource, the City Manager shall find that:
i. 
The contributing resource is a severe hazard to public health or safety; or
ii. 
Loss of the contributing resource will not affect the integrity of the Historic District; and adequate effort has been made to seek a relocation site within the Historic District.
The findings of fact regarding the historical or architectural significance for the designation of the Historic District shall be used as the primary factual basis upon which decisions are based concerning the Historic District’s significance.

f. 
Additional Criteria for Reviewing Authority’s Deliberations.
The following criteria shall be met when approving applications under subsections 7.b through 7.d of this section:
i. 
Building Height:
Existing building height should be maintained. Raising or lowering a structure’s permanent elevation when constructing a foundation should be avoided, except as required by Building Code or floodplain requirements.
ii. 
Horizontal Additions:
The scale and proportion of building additions, including the relationship of windows to walls, shall be visually compatible with the traditional architectural character of the historic building. Contemporary construction is acceptable if the design respects the building’s original architectural style and is compatible with the original scale, materials, window and door opening proportions of the structure.
iii. 
Roof Form:
Alteration of roof pitches, roof shapes, and materials should maintain the architectural style of the building.
iv. 
Rehabilitation Work:
Preserve existing historic building elements or replace with building elements and materials that replicate the historic elements, as documented through verifiable evidence, such as photographs.
v. 
Window Restoration:
Windows (frames, sashes, muntins, glazing, sills, heads, hoodmolds, paneled or decorated jambs, moldings and exterior shutters) that define the historic character of the building should be retained and preserved. This is achieved by:
(1) 
Protecting and maintaining the wood and architectural metal that comprise the window frame, sash and muntins.
(2) 
Making windows weathertight by reglazing, recaulking and replacing or installing weather-stripping.
(3) 
Repairing window frames and sashes by patching, splicing, consolidating or otherwise reinforcing, and replacing in kind parts that are extensively deteriorated or missing.
(4) 
Replacing a window in kind that is documented to be too deteriorated to repair.
vi. 
Window Replacement:
Window replacements shall match the original windows in materials and appearance. The original number of window panes (or lights) shall be maintained or restored when window replacements are required. Double-pane windows may be installed if:
(1) 
No observable tinting of the glass panes is used.
(2) 
A spacer bar is present between the inner and outer mullion.
(3) 
The same trapezoidal profile of the outside putty seam is used.
(4) 
The same frame size as the original windows is used.
(5) 
The same inside profile is used.
vii. 
Signs, Lighting, Landscaping, Fences:
Signs, lighting, and other appurtenances, such as walls, fences, awnings, and landscaping, shall be visually compatible with the scale and traditional architectural character of the historic building.
viii. 
Additional Standards (Secretary of Interior Standards).
(1) 
Retention of Original Construction:
A property shall be used for its historic purpose or be placed in a new use that requires minimal change to the defining characteristics of the building and its site and environment.
(2) 
Historic Integrity:
The historic integrity of the property shall be retained and preserved. The removal of historic materials or alteration of features and spaces that characterize a property shall be avoided.
(3) 
Time Period Consistency:
Each property shall be recognized as a physical record of its time, place, and use. Changes that create a false sense of historical development, such as adding conjectural features or architectural elements from other buildings, shall not be undertaken.
(4) 
Historic Changes:
Most properties change over time; those changes that have acquired historic significance in their own right shall be retained and preserved.
(5) 
Distinctive Architectural Features:
Distinctive features, finishes, and construction techniques or examples of craftsmanship that characterize a property shall be preserved.
(6) 
Preservation, Restoration and Rehabilitation:
Deteriorated historic features shall be repaired rather than replaced. Where the severity of deterioration requires replacement of a distinctive feature, the new feature shall match the old in design, color, texture, and other visual qualities and, where possible, materials. Replacement of missing features shall be substantiated by documentary, physical, or pictorial evidence.
(7) 
Appropriate Treatments:
Chemical or physical treatments, such as sandblasting, that cause damage to historic materials shall not be used. The surface cleaning of structures, if appropriate, shall be undertaken using the gentlest means possible.
(8) 
Archaeology:
Significant archaeological resources affected by a project shall be protected and preserved. If such resources must be disturbed, mitigation measures shall be undertaken.
(9) 
New Additions:
New additions, exterior alterations, or related new construction shall not destroy historic materials that characterize the property. The new work shall be differentiated from the old and shall be compatible with the massing, size, scale, and architectural features to protect the historic integrity of the property and its environment.
(10) 
Reversibility:
New additions and adjacent or related new construction shall be undertaken in such a manner that if removed in the future, the essential form and integrity of the historic property and its environment would be unimpaired.

The land division or lot line adjustment does not result in a landmark or contributing resource being split into separate lots.
ii. 
The land division or lot line adjustment plat or map requires adequate setbacks from landmark or contributing resource improvements to provide for buffering and mitigation of impacts associated with development on the resulting parcels.
iii. 
Yard and landscaped areas including large trees and shrubs that contribute to its historical or architectural significance shall be retained, unless landscaping conflicts with utilities or other requirements of this section or applicable City, state or federal regulations. (The reviewing authority may require replacement landscaping as mitigation under these circumstances.)
The findings of fact regarding the historical or architectural significance of the yard and landscaped area as stated in the landmark’s designation shall be used as the primary factual basis upon which decisions are based concerning retention of yard and landscaped areas.
c. 
Considerations of HRAB Recommendation.
Where HRAB is not the reviewing authority for development applications involving historic resources, the reviewing authority shall consider the recommendations by HRAB.
