* Code reviser’s note: Ordinance 6672 amended these notes and unintentionally omitted the amendments made by Ordinance 6626. At the city’s request, the amendments of Ordinance 6626 have been retained.

(1)Side yard setback in R-30 Districts increases to 20 feet on any side yard where structure exceeds 30 feet above finished grade.

(2)All rear and side yards shall contain landscaping as required by LUC 20.20.520.

(3)See LUC 20.20.012.

(4)See LUC 20.20.015.

(5)Except in transition areas, the maximum allowable building height in R-20 Districts may be increased to 40 feet if ground floor or underground parking for that building is provided and occupies a minimum of 75 percent of the building footprint.

(6)The maximum allowable building height is 75 feet on any property designated OLB which lies within 475 feet of the right-of-way of I-405, between I-90 and SR-520.

(7)Intentionally deleted.

(8)Any office building or any office portion of a building in the PO, O, OLB, LI, GC, NB, CB or F1 Districts shall comply with the following limitations on Floor Area Ratio:

(9)The maximum building height may be exceeded upon approval of the Director of the Development Services Department. Requests for such approval shall be processed in accordance with the administrative conditional use procedure of Part 20.30E LUC. Before granting any such approval, the Director of the Development Services Department must find that:

(10)Except in transition areas, the allowable building height of any building located in PO, O, OLB, GC, NB, or CB Districts may be increased by 1 story, but not to exceed 15 feet, if basement parking for that building occupies a minimum of 75 percent of the building footprint.

(11)The LUC contains enhanced setback requirements for churches, clubs, and institutions (refer to LUC 20.20.190) and schools (refer to LUC 20.20.740) located in residential land use districts.

(12)For each square foot of lot area devoted to open space in excess of 30 percent of the total lot area, 1 square foot is added to the lot area for the purpose of calculating density.

(13)Lot coverage is calculated after subtracting all critical areas and stream critical area buffers; provided, that coal mine hazards (LUC 20.25H.130), habitat associated with species of local importance (LUC 20.25H.150), and seismic hazards (LUC 20.25H.120.A.4) shall not be subtracted.

(14)Maximum lot coverage by structures is determined after public right-of-way and private roads are subtracted from the gross land area.

(15)Except for sites in the Critical Areas Overlay District, if there is a conflict between the minimum lot area and the permitted number of dwelling units per acre, the minimum lot area controls. Density/intensity on sites in the Critical Areas Overlay District is calculated pursuant to LUC 20.25H.045.

(16) Exceptions to Lot Coverage: Although not considered structures for purposes of calculating lot coverage, the following may be considered impervious surfaces subject to the impervious surface limits. See LUC 20.20.460 and 20.50.026.

(17)If the setback abuts a street right-of-way, access easement or private road, the minimum dimension is 10 feet unless a greater dimension is specified.

(18)See LUC 20.20.030 for designation and measurement of setbacks.

(19)(Repealed by Ord. 6670).

(20)See LUC 20.25H.035 for additional critical area setbacks.

(21)See LUC 20.25H.045 for calculation of density/intensity on sites in the Critical Areas Overlay District.

(22)Density for senior citizen dwelling, congregate care senior housing, and assisted living is calculated as follows: Units less than 600 square feet count as 1/2 unit and units 600 square feet or greater count as 1 unit.

(23)This residential density may be in addition to FAR only for senior citizen dwellings, assisted living and congregate care senior housing.

(24)Lot coverage may be increased to 50 percent if congregate care senior housing, senior citizen dwellings, assisted living or nursing homes are constructed on site; provided, however, that coverage for the nonresidential portions of the development cannot exceed the maximum limits indicated. Lot coverage within NB and NMU Districts may be increased to 50 percent for mixed use development which includes residential uses comprising at least 1/2 the square footage of the building footprint. Underground parking in excess of 50 percent of the site area shall not be included in lot coverage calculations.

(25)The maximum building height for structures is increased to 30 feet only if residential uses or administrative office uses are provided on the second floor, and provided the structure does not exceed 2 stories. For purposes of this note, a story is defined pursuant to the International Building Code, Section 202, as adopted and amended by the City of Bellevue.

(26)See LUC 20.20.125 for specific requirements applicable to detached accessory structures.

(27)Lot coverage for schools located in residential land use districts is limited to 35 percent of the site area (refer to LUC 20.20.740).

(28)Dimensional requirements for the F1 Land Use District are listed in LUC 20.25F1.040.

(29)(Repealed by Ord. 5726).

(30)(Repealed by Ord. 5726).

(31)Any office building or any office portion of a building in the F2 District may not exceed a Floor Area Ratio of 0.75 FAR.

(32)The maximum FAR for the combined properties in the F3 Land Use District, regardless of use, shall be 1.26 FAR; provided, that individual parcels or portions of property lying within the F3 Land Use District may have FAR for those individual parcels or portions which exceed an FAR of 1.26; provided, that the FAR calculated for the entire aggregated property within the F3 Land Use District shall not exceed 1.26. The maximum FAR permitted herein is based on a maximum total development, including existing and new development of 950,000 square feet, calculated in the same manner as provided for in the calculation of FAR. In the event of an inconsistency between the FAR maximum of 1.26 and the maximum total development amount of 950,000 square feet, the latter shall control.

(33)In no event shall building height exceed 324 feet above sea level, based on North American Vertical Datum, 1988 (NAVD – 88).

(34)Maximum building height south of the F3 Land Use District Separation Line shall be 135 feet, with structural elements not intended for habitation above 135 feet, so long as structural elements do not exceed 275 feet above sea level based on NAVD – 88.

(35)See LUC 20.20.460 for exceptions and performance standards relating to impervious surface.

(36)Impervious surface limits for legally established nonconforming nonresidential uses and for new allowed nonresidential uses in these residential land use districts shall be 80 percent.

(37)Maximum hard surface, maximum impervious surface and maximum lot coverage by structures are independent limitations on allowed development. All areas of lot coverage by structures are included in the calculation of total maximum impervious surface, unless such structures are excepted under LUC 20.20.460. All areas of impervious surface coverage shall be included in the calculation of total maximum hard surface.

(38)Certain noncritical area setbacks on sites in the Critical Areas Overlay District may be modified pursuant to LUC 20.25H.040.

(39)These dimensional standards may be modified through an approved conservation subdivision, LUC 20.45A.060, or conservation short subdivision, LUC 20.45B.055.

(40)The greenscape requirements of this section shall be imposed any time a permit, approval, or review, including land alteration or land development for Single-Family Land Use Districts, is required by the Bellevue City Code or Land Use Code. Existing single-family front yard setbacks legally established on a site prior to January 1, 2008, which do not meet the minimum greenscape requirements set forth in Chart 20.20.010 shall not be considered nonconforming. The City shall not, however, approve proposals to decrease the greenscape percentage set forth in Chart 20.20.010 where a site already falls below the minimum greenscape requirements. Where an existing site falls below the minimum requirements set forth in Chart 20.20.010, the removal of greenscape shall not be approved unless an equal amount of existing impervious surface, pervious surface, or hardscape is removed, such that the net amount of greenscape is unchanged. The Director may modify the requirements of Chart 20.20.010 for nonconforming lots, corner lots, or lots with unique sizes and shapes. See LUC 20.50.022 for the definition of greenscape.

Refer to LUC 20.50.012 for definition of “Building Height – Single-Family Uses in Single-Family Land Use Districts.”

(45)For new single-family residential homes and additions in Single-Family Land Use Districts, the maximum height of any individual building façade is 40 feet measured from the existing grade at the building wall to the ridge of a pitched roof or top of a flat roof. New single-family homes constructed as part of a subdivision pursuant to Part 20.45A LUC or planned unit development pursuant to Part 20.30D LUC are exempt from this requirement.

(46)Maximum building height in CB Districts of the Wilburton Subarea that are located between 116th Ave NE and the BNSF Corridor is 75 feet.

(47)See LUC 20.20.425 for exceptions and performance standards related to hard surfaces.
