City of Hillsboro, OR ORENCO PLAN DISTRICT

§ 12.62.100 Purpose.

The geographically specific Orenco Plan District development regulations and design standards reflect the City's goals and objectives for the Orenco SCPA, as described in Comprehensive Plan Section 24. These regulations were developed from 2 sources:

The report of the Orenco Station Community Planning Advisory Team; and

Public participation by the community including the Orenco Neighborhood Organization.

The purpose of the specific design standards in Subchapter 12.62 applicable to the historic Orenco Townsite Conservation zone is to conserve the historical and cultural significance of the original community area by:

Preserving and restoring the plat layout of the original 1908 community and its 1911 addition;

Respecting the historic character of the original townsite streetscapes as designed by the Oregon Nursery Company, by adopting unique street standards, including the following:

Narrow paved streets with gravel shoulders;

Preservation of the existing mature street trees and replanting missing trees;

Use of street side grass drainage swales for stormwater removal;

Provision of pedestrian access through surfaced alleys and property line sidewalks in selected locations;

Use of ornamental streetlights to provide public safety with lower lighting levels befitting the historic neighborhood.

Requiring that new residential structures be of compatible character and architectural style as those built between 1900 and 1930, including but not limited to: architectural style and features, materials, paint and finishes as listed in Subsection 12.62.400.B;

Requiring that alterations to existing residential structures be consistent with the architectural style, materials and colors of the existing structures;

Requiring that new commercial and institutional structures be of compatible character and architectural style as those built between 1900 and 1930, including, but not limited to: architectural style and features, materials, paint and finishes as listed in Subsection 12.62.400.C; and

Requiring that alterations to existing commercial and institutional structures be consistent with the architectural style, materials and colors of the existing structures.

The purpose of the regulations and standards applicable to the Orenco Station sub-area is to create a compact, transit-supportive mixed-use neighborhood with reduced automobile reliance by:

Requiring a mix of housing types, with the goal of achieving at least 1,834 dwelling units within the SCR-V zoned area;

Using the light rail streetscape design standards in Section 12.50.530 to reduce street right-of-way and travel lane widths, and to provide alleys, sidewalks and pedestrian amenities appropriate to higher density neighborhoods;

Allowing mixed-uses within the SCR-V zone, offering services and employment opportunities for neighborhood residents;

Providing for parks and open spaces for recreation outdoor activity within walking distance of residential areas; and

Creating interconnected pedestrian routes to provide safe and convenient means to walk among neighborhood destinations and to activity centers outside the area.

Except as provided in this section, all properties within the Orenco Plan District will be developed in accordance with the standards of the applicable zone.

(Ord. 6250 § 1, 2017; Ord. 6322 § 1, 2019; Ord. 6323 § 1, 2019; Ord. 6401 § 1, 2022)

§ 12.62.200 Applicability.

The standards of this subchapter apply to properties within the Orenco Plan District boundaries as shown on Figure 12.62.200-A. There are 4 zones applicable within the Orenco Plan District:

Station Community Residential – Orenco Townsite Conservation (SCR-OTC);

Station Community Residential – Village (SCR-V);

Station Community Commercial – Station Commercial (SCC-SC); and

Station Community Industrial (SCI).

§ 12.62.300 Standards Specific to the Orenco Townsite Area.

Historic Context: In the early 1900s the Oregon Nursery Company purchased over 1100 acres east of Hillsboro. Company officials platted a small town for their workers just south of the Oregon Electric Railway, and the community was incorporated as Orenco (an abbreviation of the company name). By 1910, with a population of almost 500, Orenco had its own urban amenities: a post office and town hall, fire station and elementary school, stores, a hotel, and a newspaper. Street names in the town reflected the nursery heritage: Alder; Birch; Chestnut; Dogwood; Elm; and Fir. When the Oregon Nursery Company fell on hard times and dissolved during the Great Depression, the town disincorporated and declined.

In the late 1900s, as Hillsboro grew eastward and the Westside Light Rail Project reactivitated the abandoned Oregon Electric Railway right-of-way, the City of Hillsboro adopted new zoning for the historic Orenco neighborhood.

The SCR-OTC Station Community Residential-Orenco Townsite Conservation District standards in Section 12.21.700 and the standards in section for the Orenco Townsite sub-area are intended to reflect the historic fabric of the area.

Minimum and Maximum Lot Size.

Legal lots of record as of August 15, 1996 that are smaller than 7,500 sq. ft. may be developed for residential or commercial use under the regulations and standards of the SCR-OTC zone and paragraph 2 below, except that triplexes, quadplexes, and cottage clusters are not permitted on lots smaller than 7,500 sq. ft.

If allowed in paragraph 1 above, lots with substandard dimensions (area less than 7,500 sq. ft., width less than 50 feet, and/or depth less than 150 feet) may be developed for residential use only if the lot is accessible from a street or alley consistent with the original Townsite street pattern. Lots which are not accessible cannot be developed except in conjunction with an adjacent full-sized lot under common ownership.

Within the boundaries of the original 1908 Orenco Townsite plat and the 1911 First Addition to Orenco plat, legal lots of record as of August 15, 1996 that were larger than 7500 sq. ft. can only be partitioned or subdivided into 7500 sq. ft. lots, 50 feet wide and 150 feet deep, including dedications required for alleys but excluding dedications required for streets. Partitions or subdivision lotting patterns shall replicate those of the original 1908 and 1911 plats. Townhouse lots and middle housing land divisions are exempt from these standards.

Outside the boundaries of the original 1908 and 1911 plats, lots of record as of August 15, 1996 may be divided to extend the existing street and alley system, or to create an equivalent and similar street and alley system, allowing development of 7500 sq. ft. lots.

Lots with frontage on NE Alder St between NE 68th Ave and NE Century Blvd and townhouse lots are exempt from the 7,500 sq. ft. minimum area, 50 foot minimum width, and 150 foot minimum depth requirement.

Minimum and Maximum Setbacks.

Side setbacks may be reduced to zero feet to allow construction of a shared-ownership garage across a property line.

Minimum setbacks on alleys shall be as follows:

16 feet for residential structures, including accessory dwelling units;

Four feet for fences and accessory structures.

Except as provided in paragraph 4, below, a detached accessory dwelling unit must be constructed within 50 feet of the rear property line.

If a lot is adjacent to an inventoried Significant Natural Resource Area (such as the Rock Creek floodplain), a detached accessory dwelling unit may be sited in front of, rather than behind, the primary dwelling.

Mixed-Use Buildings. Lots having frontage on NE Alder St between NE 68th Ave and NE Century Blvd may be developed with mixed-use neighborhood commercial and/or residential uses.

Landscaping Requirements. The Review Authority shall condition all development approvals with landscaping requirements as follows:

Street trees shall be planted along all street frontages identified as "Street Tree Planting Locations" in Figure 12.62.300-A. Street trees shall be planted at the following spacing: 1 tree per 65 feet; provided that at least 1 tree is required on each lot with street frontage.

Street trees and on-site landscape plantings shall be selected from the Orenco Townsite Planting List (Table 12.62.300-1). At planting, street trees shall be sized at a minimum 2½-inch caliper (deciduous) or 6 feet tall (evergreen). Replacement elm trees shall be disease-resistance species only, such as Homestead Elm, Zelcova Serrata ("Village Green" variety), or equivalent species if requested by the applicant and approved by the Review Authority.
