ZDO 510

ZDO 510: Neighborhood Commercial (NC), Community Commercial (C-2), Regional Center Commercial (RCC), Retail Commercial (RTL), Corridor Commercial (CC), General Commercial (C-3), Planned Mixed Use (PMU), Station Community Mixed Use (SCMU), Office Apartment (OA), Office Commercial (OC), And Regional Center Office (PCO) Districts

510.01 Purpose

Section 510 is adopted to implement the policies of the Comprehensive Plan for the Neighborhood Commercial zoning district and Community Commercial, Regional Center Commercial, Retail Commercial, Corridor Commercial, General Commercial, Planned Mixed Use, Station Community Mixed Use, Office Apartment, Office Commercial, and Regional Center Office areas.

510.02 Applicability

Section 510 applies to land in the Neighborhood Commercial (NC) Community Commercial (C-2), Regional Center Commercial (RCC), Retail Commercial (RTL), Corridor Commercial (CC), General Commercial (C-3), Planned Mixed Use (PMU), Station Community Mixed Use (SCMU), Office Apartment (OA), Office Commercial (OA), and Regional Center Office (RCO) Districts, hereinafter collectively referred to as the urban commercial and mixed-use zoning districts.

510.03 Uses Permitted

Uses permitted in each zoning district are listed in Table 510-1, Permitted Uses in the Urban Commercial and Mixed-Use Zoning Districts. In addition, uses similar to one or more of the listed uses for the applicable zoning district may be authorized pursuant to Section 106, Authorizations of Similar Uses.

  1. As used in Table 510-1:
    1. "P" means the use is a primary use.
    2. "A" means the use is an accessory use.
    3. "L" means the use is a limited use and shall be developed concurrently with, or after, a primary use.
    4. C" means the use is a conditional use, approval of which is subject to Section 1203, Conditional Uses.
    5. "S" means the use may be authorized only pursuant to Section 106; however, identifying a use as "S" does not indicate that any determination has been made regarding whether the use will be authorized pursuant to Section 106.
    6. "X" means the use is prohibited.
    7. Numbers in superscript correspond to the notes that follow Table 510-1.
  2. If a use is identified in Table 510-1 as prohibited, it is prohibited even if it also falls within a broader use description that is permitted in the applicable zoning district. For example, a car wash may be prohibited even if commercial services in general are permitted.
  3. If a use is included in more than one use description in Table 510-1, the more specific listing applies. For example, if a car wash is a conditional use, but commercial services in general are a primary use, the car wash shall be reviewed as a conditional use. Notwithstanding this provision, a use may be included in two of the following categories because it is allowed with fewer restrictions in one category than another: primary, accessory, limited, and conditional. In that case, the use may be approved in either category, to the extent that it complies with the respective approval criteria. For example, child care facilities may be permitted as a limited use with a maximum building floor area and as a conditional use without a maximum building floor area.
  4. Permitted uses are subject to the applicable provisions of Subsection 510.04, Dimensional Standards, Subsection 510.05, Development Standards, Section 1000, Development Standards, and Section 1100, Development Review Process.

1 The minimum lot size for land with a Comprehensive Plan land use plan designation of Low Density Residential shall be the same as that allowed by the zoning district that applied to the subject property immediately prior to the application of the NC zoning district.

2 The minimum lot size standard applies only to subdivisions, partitions, and property line adjustments. Notwithstanding the minimum lot size standard, an undersized lot of record may be developed, subject to other applicable standards of this Ordinance.

3 No minimum lot size standard applies to a lot created by partition or subdivision or adjusted through a property line adjustment, provided that the newly created or adjusted lot is developed only with a dwelling classified as a nonconforming use and uses accessory to that dwelling.

4 The minimum is 2,000 square feet for a lot developed only with a townhouse and uses accessory to that townhouse.

5 The minimum street frontage standard applies only to subdivisions, partitions, and property line adjustments. The minimum for a lot of record on the outer radius of a curved street or the circular end of a cul-de-sac is 35 feet measured on the arc. The minimum for a lot of record developed only with a townhouse, and uses accessory to that townhouse, shall be 20 feet. A lot of record with frontage on more than one street shall meet the minimum on each street.

6 The maximum front setback standard applies only if required by Subsection 1005.02(H). However, see Subsection 1005.02(E) for a related standard.

7 The maximum front setback standard shall be met for all buildings except freestanding parking structures. However, the maximum front setback may be exceeded to the minimum extent necessary to accommodate pedestrian amenities. If a lot has more than one front lot line, the standard must be met for only one. A private road used to satisfy the maximum front setback standard must comply with Subsection 1005.07(G). The maximum front setback from Main Streets identified on Comprehensive Plan Map X-CRC-3 is 10 feet.

8 In lieu of complying with the standard, an applicant for design review on a site of 25 acres or larger may propose alternate setback standards. The alternate standards, or any part thereof, shall be approved if they are found to be equally effective as the regular standards in establishing a visual image, sense of place, and quality pedestrian environment for the area.

9 There is no minimum setback from a front lot line that abuts a Main Street identified on Comprehensive Plan Map X-CRC-3.

10 If the rear lot line abuts a residential zoning district, the minimum shall be 15 feet.

11 If the rear lot line abuts a residential zoning district, the minimum shall be 35 feet.

12 If the rear lot line abuts a residential zoning district, the minimum shall be 15 feet plus one foot for each one-foot increase in building height over 35 feet. Height increments of less than one foot shall be rounded up to the nearest foot. For example, if the building height is 38.8 feet, the minimum setback shall be 19 feet.

13 If the rear lot line abuts an Urban Low Density Residential, VR-4/5, or VR-5/7 zoning district, the minimum shall be: 10 feet for the portion of a building that is 25 feet or less in height; 20 feet for the portion of a building that is greater than 25 feet and less than or equal to 35 feet in height; and 40 feet for the portion of a building that is greater than 35 feet and less than or equal to 45 feet in height.

14 If the rear lot line abuts a residential zoning district, the minimum shall be 35 feet plus one foot for each one-foot increase in building height over 35 feet.

15 If the side lot line abuts a residential zoning district, the minimum shall be 15 feet.

16 If the side lot line abuts a residential zoning district, the minimum side yard setback shall be 15 feet plus one foot for each one-foot increase in building height over 35 feet. Height increments of less than one foot shall be rounded up to the nearest foot. For example, if the building height is 38.8 feet, the minimum setback shall be 19 feet.

17 If the side lot line abuts an Urban Low Density Residential, VR-4/5, or VR-5/7 zoning district, the minimum shall be: six feet for the portion of a building that is 25 feet or less in height; 16 feet for the portion of a building that is greater than 25 feet and less than or equal to 35 feet in height; and 40 feet for the portion of a building that is greater than 35 feet and less than or equal to 45 feet in height.

18 If the side lot line abuts a residential zoning district, the minimum shall be 35 feet.

19 If the subject property abuts a residential zoning district, the maximum building height shall be 35 feet.

20 If the building is located less than 100 feet from an Urban Low Density Residential, VR-4/5, or VR-5/7 District, the maximum building height shall be equal to the building's distance from the Urban Low Density Residential, VR-4/5, or VR-5/7 District.

21 Floor area ratio shall be calculated pursuant to Subsection 1005.02(K).

22 With a master plan approved pursuant to Subsection 1102.03(B), a lot greater than two and one-half acres may be developed in phases provided that the minimum floor area ratio of each phase prior to the final phase is 0.5 and that the minimum floor area ratio of 1.0 is achieved for the entire lot with development of the final phase.

23 For the purposes of this provision, "office uses" include the following uses from Table 510-1, Permitted Uses in the Urban Commercial and Mixed-Use Zoning Districts: Business Services, Financial Institutions, Information Services, Offices, Offices and Outpatient Clinics, and Research Facilities and Laboratories.

      1. The primary safety zone is a fire fuel break extending a minimum distance around structures. The minimum distance is established by Table 406-2, Minimum Primary Safety Zone and Figure 406-1, Example of Primary Safety Zone. The goal within the primary safety zone is to remove fuels that will produce flame lengths in excess of one foot. Vegetation within the primary safety zone may include green lawns and shrubs less than 24 inches in height. Trees shall be spaced with greater than 15 feet between the crowns and pruned to remove dead and low (less than eight feet) branches. Accumulated leaves, needles, limbs and other dead vegetation shall be removed from beneath trees. Nonflammable materials (i.e., rock) instead of flammable materials (i.e., bark mulch) shall be placed next to the structure. As slope increases, the primary safety zone shall increase away from the structure and down the slope at a 45-degree angle from the structure, in accordance with Table 406-2 and Figure 406-1:

Table 406-2: Minimum Primary Safety Zone

Diagram of Safety Zone shape

  1. For any new dwelling, a secondary fuel-free break area shall be cleared and maintained on land surrounding the dwelling that is owned or controlled by the owner.
    1. The secondary fuel-free break extends around the primary safety zone required pursuant to Subsection 406.08(A)(1). The goal of the secondary fuel-free break shall be to reduce fuels so that the overall intensity of any wildfire would be lessened and the likelihood of crown fires and crowning is reduced. Vegetation within the secondary fuel-free break shall be pruned and spaced so that fire will not spread between crowns of trees. Small trees and brush growing underneath larger trees shall be removed to prevent spread of fire up into the crowns of the larger trees. Dead fuels shall be removed. The minimum width of the secondary fuel-free break shall be the lesser of:
      1. 100 feet; or
      2. The distance from the dwelling to the edge of land surrounding the dwelling that is owned or controlled by the owner.
  2. Structures within a River and Stream Conservation Area or the Willamette River Greenway shall be sited consistent with the requirements of Sections 704, River and Stream Conservation Area (RSCA) and 705, Willamette River Greenway (WRG), respectively. Structures shall be sited so that a primary safety zone can be completed around the structure outside of the river or stream corridor setback/buffer area. The area within the river or stream setback/buffer area shall be exempt from the secondary fuel-free break area requirements.
  3. The fuel-free break standards shall be completed and approved prior to issuance of any septic, building, or manufactured dwelling permits. Maintenance of the fuel-free breaks shall be the continuing responsibility of the property owner.
  4. Additional Fire-Siting Standards for New Dwellings: The following fire-siting standards shall apply to any new dwelling approved pursuant to a land use application based on standards in effect on or after February 5, 1990:
    1. The dwelling shall be located upon a parcel within a fire protection district or shall be provided with residential fire protection by contract. If the dwelling is not within a fire protection district, the applicant shall provide evidence that the applicant has asked to be included within the nearest such district. If inclusion within a fire protection district or contracting for residential fire protection is impracticable, an alternative means for protecting the dwelling from fire hazards shall be provided. The means selected may include a fire sprinkling system, onsite equipment and water storage, or other methods that are reasonable, given the site conditions. If a water supply is required for fire protection, it shall be a swimming pool, pond, lake, or similar body of water that at all times contains at least 4,000 gallons or a stream that has a continuous year round flow of at least one cubic foot per second. The applicant shall provide verification from the Oregon Water Resources Department that any permits or registrations required for water diversion or storage have been obtained or that permits or registrations are not required for the use. Road access shall be provided to within 15 feet of the water's edge for firefighting pumping units. The road access shall accommodate the turnaround of firefighting equipment during the fires season. Permanent signs shall be posted along the access route to indicate the location of the emergency water source.
    2. The dwelling shall have a fire retardant roof.
    3. The dwelling shall not be sited on a slope of greater than 40 percent.
    4. If the dwelling has a chimney or chimneys, each chimney shall have a spark arrester.
  5. Compatibility Siting Standards: The following compatibility siting standards shall apply to any new structure, including any new dwelling, approved pursuant to a land use application based on standards in effect on or after April 28, 1994:
    1. Structures shall be sited on the subject property so that:
      1. They have the least impact on nearby or adjoining forest or agricultural lands;
      2. The siting ensures that adverse impacts on forest operations and accepted farming practices on the tract will be minimized;
      3. The amount of forest lands used to site access roads, service corridors, and structures is minimized; and
      4. The risks associated with wildfire are minimized.
    2. Siting criteria satisfying Subsection 406.08(C)(1) may include setbacks from adjoining properties, clustering near or among existing structures, siting close to existing roads, and siting on that portion of the subject property least suited for growing trees.
  6. The applicant shall provide evidence that the domestic water supply is from a source authorized in accordance with the Oregon Water Resources Department's (OWRD) administrative rules for the appropriation of ground water or surface water and not from a Class II stream as defined in the Oregon Forest Practices Rules (OAR chapter 629). Evidence of a domestic water supply means:
    1. Verification from a water purveyor that the use described in the application will be served by the purveyor under the purveyor's rights to appropriate water;
    2. A water use permit issued by the OWRD for the use described in the application; or
    3. Verification from the OWRD that a water use permit is not required for the use described in the application. If the proposed water supply is from a well and is exempt from permitting requirements under Oregon Revised Statutes 537.545, the applicant shall submit the well constructor's report to the County upon completion of the well.

      10. In order to identify the commercial farm or ranch tracts to be used in Subsection 401.05(C)(9)(a), the gross sales capability of each tract in the study area, including the subject tract, must be determined, using the gross sales figures prepared by the county pursuant to Subsection 401.05(C)(9)(k) as follows:
        1. Identify the study area. This includes all land in the tracts wholly or partially within one mile of the perimeter of the subject tract;
        2. Determine for each tract in the study area the number of acres in every land classification from the county assessor's data;
        3. Determine the potential earning capability for each tract by multiplying the number of acres in each land class by the gross sales per acre for each land class provided by the Land Conservation and Development Commission pursuant to Subsection 401.05(C)(9)(k). Add these to obtain the potential earning capability for each tract;
        4. Identify those tracts capable of grossing at least $10,000 based on the data generated in Subsection 401.05(C)(9)(j)(iii); and
        5. Determine the median size and median gross sales capability for those tracts capable of generating at least $10,000 in annual gross sales to use in Subsections 401.05(C)(9)(a) and 401.05(C)(9)(c).
      11. In order to review a farm dwelling pursuant to Subsection 401.05(C)(9)(a), the county may prepare, subject to review by the director of the Department of Land Conservation and Development, a table of the estimated potential gross sales per acre of each assessor land class (irrigated and nonirrigated) required by 401.05(C)(9)(j). The director shall provide assistance and guidance to the county in preparation of this table. The table shall be prepared as follows:
        1. Determine up to three indicator crop Type s with the highest harvested acreage for irrigated and for nonirrigated lands in the county using the most recent OSU Extension Service Commodity Data Sheets, Report No. 790, "Oregon County and State Agricultural Estimates," or other USDA/Extension Service documentation;
        2. Determine the combined weighted average of the gross sales per acre for the three indicator crop Type s for irrigated and for nonirrigated lands, as follows: (1) Determine the gross sales per acre for each indicator crop Type for the previous five years (i.e., divide each crop Type 's gross annual sales by the harvested acres for each crop Type ); (2) Determine the average gross sales per acre for each crop Type for three years, discarding the highest and lowest sales per acre amounts during the five-year period; (3) Determine the percentage each indicator crop's harvested acreage is of the total combined harvested acres for the three indicator crop Type s for the five year period; (4) Multiply the combined sales per acre for each crop Type identified under Subsection 401.05(C)(9)(k)(ii)(2) by its percentage of harvested acres to determine a weighted sales per acre amount for each indicator crop; and (5) Add the weighted sales per acre amounts for each indicator crop Type identified in Subsection 401.05(C)(9)(k)(ii)(4). The result provides the combined weighted gross sales per acre.
        3. Determine the average land rent value for irrigated and nonirrigated land classes in the EFU District according to the annual "income approach" report prepared by the county assessor pursuant to ORS 308A.092; and
        4. Determine the percentage of the average land rent value for each specific land rent for each land classification determined in Subsection 401.05(C)(9)(k)(iii). Adjust the combined weighted sales per acre amount identified in Subsection 401.05(C)(9)(k)(ii)(5) using the percentage of average land rent (i.e., multiply the weighted average determined in Subsection 401.05(C)(9)(k)(ii)(5) by the percent of average land rent value from Subsection 401.05(C)(9)(k)(iii)). The result provides the estimated potential gross sales per acre for each assessor land class that will be provided to the county to be used as explained under Subsection 401.05(C)(9)(j)(iii).
    10. Dwelling not in conjunction with a farm use: A dwelling for a nonfarm use may be allowed subject to the following criteria:
      1. The dwelling or activities associated with the dwelling will not force a significant change in or significantly increase the cost of accepted farm or forest practices on nearby lands devoted to farm or forest use; 
      2. The dwelling will be sited on a lot of record that is predominantly composed of Class IV through Class VIII soils that would not, when irrigated, be classified as prime, unique, Class I or Class II soils; 
      3. The dwelling will be sited on a lot of record lawfully created before January 1, 1993.
      4. The dwelling shall not materially alter the stability of the overall land use pattern of the area. In determining whether a proposed nonfarm dwelling will alter the stability of the land use pattern in the area, the County shall consider the cumulative impact of possible new nonfarm dwellings and parcels on other lots of record in the area similarly situated. To address this standard, the following shall be done:
        1. Identify a study area for the cumulative impacts analysis. The study area shall include at least 2,000 acres or a smaller area not less than 1,000 acres, if the smaller area is a "distinct agricultural area" based on topography, soils Type s, land use pattern, or the Type of farm operations or practices that distinguish it from other adjacent agricultural areas. Findings shall describe the study area, its boundaries, and the location of the subject parcel within this area, why the selected area is representative of the land use pattern surrounding the subject parcel and is adequate to conduct the analysis required by this standard. Lands zoned for rural residential or other urban or nonresource uses shall not be included in the study area;
        2. Identify within the study area the broad Type s of farm uses (irrigated or nonirrigated crops, pasture, or grazing lands), the number, location, and Type of existing dwellings (farm, nonfarm, hardship, etc.), and the dwelling development trends since 1993. Determine the potential number of nonfarm/lot-of-record dwellings that could be approved under Subsections 401.05(C)(2) through (4) and (10), including identification of predominant soil classifications, the parcels created prior to January 1, 1993, and the parcels larger than the minimum lot size that may be divided to create new parcels for nonfarm dwellings under ORS 215.263(4). The findings shall describe the existing land use pattern of the study area, including the distribution and arrangement of existing uses and the land use pattern that could result from approval of the possible nonfarm dwellings;
        3. Determine whether approval of the proposed nonfarm dwelling together with existing nonfarm dwellings will materially alter the stability of the land use pattern in the area. The stability of the land use pattern will be materially altered if the cumulative effect of existing and potential nonfarm dwellings will make it more difficult for the existing Type s of farms in the area to continue operation due to diminished opportunities to expand, purchase or lease farmland, acquire water rights or diminish the number of tracts or acreage in farm use in a manner that will destabilize the overall character of the study area. 
      5. The dwelling shall comply with such other conditions as the County considers necessary.
      6. Prior to Planning Director approval for issuance of a building or manufactured dwelling permit, the applicant shall notify the County Assessor that the lot of record is no longer being used for farmland and; request the County Assessor to disqualify the lot of record for special assessment under ORS 308.370, 308.765, 321.257 to 321.381, 321.730 or 321.815 and; pay any additional tax imposed upon disqualification from special assessment. A lot of record that has been disqualified pursuant to Subsection 401.05(C)(10)(f) shall not requalify for special assessment unless, when combined with another contiguous lot of record, it constitutes a qualifying parcel.

Prior conditions of approval for the subject land and dwelling remain in effect. "Foreclosure" means only those foreclosures that are exempt from partition under ORS 92.010(9)(a).
      3. A relative farm help dwelling shall be occupied by relatives whose assistance in the management and farm use of the existing commercial farming operation, such as planting, harvesting, marketing, or caring for livestock, is required by the farm operator. The farm operator shall continue to play the predominant role in the management and farm use of the farm.

1 The minimum lot size standards apply as established by Sections 1012 and 1107. Notwithstanding the minimum lot size standard, a lot of record may be developed subject to other applicable standards of this Ordinance, except minimum lot size standards of Section 800 apply.

2 In a planned unit development, there is no minimum individual lot size. However, the minimum average lot size is one acre except for lots to be developed with a duplex, in which case the minimum average lot size is two acres. The average lot size is calculated by determining the lot area of the land proposed for subdivision, partition, or replat and dividing by the number of lots or parcels in the proposed planned unit development.

3 The minimum lot size inside the Portland Metropolitan Urban Growth Boundary is 20 acres. The 20-acre minimum lot size is applicable to subdivisions, partitions, and Type II replats, but not to Type I replats or property line adjustments. Where this standard applies, it supersedes any other minimum lot size standard in Table 316-2.

4 For the purpose of complying with the minimum lot size standard, lots with street frontage on County or public road rights-of-way may include the land area between the front lot line and the centerline of the County or public road right-of-way.

5 The minimum lot size inside the urban growth boundaries of the cities of Canby, Estacada, Molalla, and Sandy is five acres.

6 The average lot size is calculated by determining the lot area of the land proposed for subdivision, partition, or replat and dividing by the number of lots or parcels in the proposed partition, subdivision, or replat.

7 In a planned unit development, the minimum individual lot size is two acres, except inside the urban growth boundaries of the cities of Canby, Estacada, Molalla, and Sandy, where the minimum individual lot size is five acres. In all cases, the minimum average lot size is 10 acres. The average lot size is calculated by determining the lot area of the land proposed for subdivision, partition, or replat and dividing by the number of lots or parcels in the proposed planned unit development.

8 In a planned unit development, the minimum front setback is 20 feet.

9 For a corner lot located above 3,500 feet in elevation, one of the minimum front setbacks is 10 feet, except 20 feet to garage and carport motor vehicle entries.

10 In a planned unit development, there are no minimum rear and side setbacks except from rear and side lot lines on the perimeter of the final plat. Where this standard applies, it supersedes any other rear or side setback standard in Table 316-2.

11 The minimum rear setback for an accessory building shall be five feet except as established by Note 10.

12 The minimum rear setback for an accessory building shall be 10 feet except as established by Note 10.

13 The minimum side setback for an accessory building shall be five feet except as established by Note 10.
