Notes:
[1]	When subdivisions are proposed, the number of lots required shall be determined by dividing the net developable area by the minimum lot size per unit required in the underlying zone, and multiplying this number by 0.8. The result shall be rounded up for any product with a fraction of 0.5 or greater and rounded down for any product with a fraction of less than 0.5. The requirements of this section are subject to the exceptions contained in LOC § 50.04.003.10, Exceptions to the Minimum Density Requirement for All Zones.
[2]	Net developable area divided by the minimum lot area per unit and rounded down to the nearest whole number. The actual density allowed on a site will be determined at the time of development review. Maximum density will be allowed to the extent that facts presented to the hearing body show that development at that density can occur within requirements set forth in the Development Standards. Duplexes, triplexes, quadplexes, and cottage cluster developments are exempt from maximum density standards. For townhouse projects, the maximum density is four dwelling units per equivalent minimum lot area required per single-family dwelling in that zone.
[3]	Up to a 25% reduction in minimum required lot area for each dwelling unit shall be allowed to permit the relocation of a designated historic landmark, when relocation has been approved by the designated hearing body.
[4]	Base building height of single-family and middle housing dwellings may be increased by one ft. for every five additional ft. in yard setback on all sides.
[5]	Maximum base height across the site shall be established by a flat plane measured at 28 ft. (R-7.5 zone) or 30 ft. (R-10 zone) above the highest point of the natural ground surface within the building envelope, unless the natural ground surface is lowered, in which case the height is measured from the lowered ground surface per the definition of "height of building" in LOC § 50.10.003.2. In no case shall the base height exceed 32 ft. (R-7.5 zone) or 34 ft. (R-10 zone). See Figure 50.04.001-A: Height Adjustment for Sloping Topography.
[6]	Building height exceptions shall not exceed the building height of the primary structure.
[7]	Cottage cluster developments are exempt from maximum floor area standards, but maximum average floor area standards shall be applied to individual cottage cluster dwellings. See LOC § 50.04.001.1.d.iv, Maximum Average Floor Area of Units in a Cottage Cluster, and LOC § 50.03.003.1.d, use-specific standards for cottage clusters.
[8]	Maximum floor area standards for townhouses shall be applied to a townhouse project, and not to individual townhouse lots or dwellings. See also LOC § 50.04.001.1.d.v, Maximum Floor Area of Townhouses.

Notes:
[1]	When subdivisions are proposed in the R-5 and R-6 zones or multi-family development is proposed in the R5 zone, the number of lots or dwelling units required shall be determined by dividing the net developable area by the minimum lot size per unit required in the underlying zone, and multiplying this number by 0.8. The result shall be rounded up for any product with a fraction of 0.5 or greater and rounded down for any product with a fraction of less than 0.5. The requirements of this section are subject to the exceptions contained in LOC § 50.04.003.10, Exceptions to the Minimum Density Requirement for All Zones. When subdivisions are proposed in the R-DD zone, the density is computed by multiplying the net developable area by either five, ten, or 14 per the applicable type of development. The result shall be rounded up for any product with a fraction of 0.5 or greater and rounded down for any product with a fraction of less than 0.5.
[2]	Net developable area divided by the minimum lot area per unit and rounded down to the nearest whole number. The actual density allowed on a site will be determined at the time of development review. Maximum density will be allowed to the extent that facts presented to the hearing body show that development at that density can occur within requirements set forth in the Development Standards. Duplexes, triplexes, quadplexes, and cottage clusters in residential zones are exempt from maximum density standards. For townhouse projects in residential zones, the maximum density is four dwelling units per equivalent minimum lot area required per single-family dwelling in that zone.
[3]	R-DD zone maximum density expressed in number of dwelling units per net developable area is computed by dividing the net developable area by 2,000 sq. ft. and rounding down to the nearest whole number. Duplexes, triplexes, quadplexes, and cottage clusters in the R-DD zone are exempt from maximum density standards. For townhouse projects in the R-DD zone, the maximum density is four dwelling units per equivalent minimum lot area required per single-family dwelling in that zone.
[4]	Except for structures that have been determined by the State or National Register of Historic Places as being of historic significance.
[5]	Lots with sloping topography – Maximum base height across the site shall be established by a flat plane measured at 28 ft. above the highest point of the natural ground surface within the building envelope, unless the natural ground surface is lowered, in which case the height is measured from the lowered ground surface per the definition of "height of building" in LOC § 50.10.003.2. In no case shall the base height exceed 32 ft. See Figure 50.04.001-A: Height Adjustment for Sloping Topography.
[6]	Cottage cluster developments are exempt from maximum floor area standards, but maximum average floor area standards shall be applied to individual cottage cluster dwellings. See LOC § 50.04.001.2.d.iv, Maximum Average Floor Area of Units in a Cottage Cluster, and LOC § 50.03.003.1.d, use-specific standards for cottage clusters.

[Cross-Reference: Height Limitation: see Charter Section 46A for 50 ft. Maximum Height of Structures in Residential Areas; LOC § 50.04.003.4, General Exception to Structure Height Limitations; LOC § 50.06.001.5.b.]

Notes:
[1]	When subdivisions are proposed in the R-W and R-3 zones or multi-family development is proposed in the R-3 zone, the number of lots or dwelling units required shall be determined by dividing the net developable area by the minimum lot size or units required in the underlying zone, and multiplying this number by 0.8. The result shall be rounded up for any product with a fraction of 0.5 or greater and rounded down for any product with a fraction of less than 0.5. The requirements of this subsection are subject to the exceptions contained in LOC § 50.04.003, Exceptions, Projections, and Encroachments.
[2]	When subdivisions are proposed in the R-2 or R-0 zones or multi-family development is proposed in the R-0 zone, minimum density is computed by multiplying the net developable area by either 20 or 12 per the applicable zone. The result shall be rounded up for any product with a fraction of 0.5 or greater and rounded down for any product with a fraction of less than 0.5. The requirements of this subsection are subject to the exceptions contained in LOC § 50.04.003, Exceptions, Projections and Encroachments.
[3]	Computed by dividing the net developable area by the minimum lot area per unit and rounding down to the nearest whole number. Duplexes, triplexes, quadplexes, and cottage clusters are exempt from maximum density standards. For townhouse projects, the maximum density is four dwelling units per equivalent minimum lot area required per single-family dwelling in that zone.
[4]	Maximum base height across the site shall be established by a flat plane measured at 28 ft. above the highest point of the natural ground surface within the building envelope, unless the natural ground surface is lowered, in which case the height is measured from the lowered ground surface per the definition of "height of building" in LOC § 50.10.003.2. In no case shall the base height exceed 32 ft. See Figure 50.04.001-A: Height Adjustment for Sloping Topography.
[5]	For any portion of the lot above the Oswego Lake surface elevation, maximum building height shall not exceed 25 ft. For any portion of the lot at or below the Oswego Lake surface elevation, maximum building height shall not exceed 27 ft. above the Oswego Lake surface elevation. The maximum building height of 27 ft. above the Oswego Lake surface elevation shall extend landward until it meets the 25 ft. height limit for the portion of the lot above the Oswego Lake surface elevation. See Figure 50.04.001-11[5].
[6]	Site-specific dimensional standards, see LOC § 50.02.002.2.c.
[7]	Cottage cluster developments are exempt from maximum floor area standards, but maximum average floor area standards shall be applied to individual cottage cluster dwellings. See LOC § 50.04.001.2.d.iv, Maximum Average Floor Area of Units in a Cottage Cluster, and LOC § 50.03.003.1.d, use-specific standards for cottage clusters.

Additional Setbacks.

The following setbacks are in addition to the setbacks in LOC § 50.04.001: LOC § 50.04.003.7 (Oswego Lake Setback) and LOC § 50.04.002 (Special Street Setbacks).

General Exception to Lot Area and Dimension Requirements.

[Ord. No. 2579, Repealed and Replaced, 3-20-2012]

Exceptions.

If a proposed partition or subdivision would result in any existing structure becoming noncomplying with any regulation of this Code, and the structure was constructed three or more years prior to the filing of the application for the partition or subdivision, the following adjustments are allowed: a 15% deviation from lot coverage, floor area, yard setback or height requirements (adjustment to yard setbacks and height may only be applied to the lot upon which the existing structure is located); or 10% deviation from the lot area, lot width, lot depth, or lot frontage standard; provided the following criteria are met:

After taking into consideration any proposed mitigation efforts, the adjustment will not have a significant negative impact on the neighborhood and adjacent properties, in terms of:

Scale;

Noise;

Parking;

Loss of privacy;

Buffers from existing properties; and

(6)

Neighborhood character.

ii.

If more than one adjustment is requested, the cumulative effect of the adjustments will not cumulatively have a significant negative impact on the neighborhood and adjacent properties in terms of the criteria listed in subsection 2.a.i of this section.

iii.

City-designated historic resources are preserved in accordance with LOC § 50.06.009.

iv.

Any impacts resulting from the adjustment are mitigated to the extent practicable.

If in an RC or RP district, the partition or subdivision shall comply with LOC § 50.05.010, Sensitive Lands Overlay Districts.

Substandard Lots or Dimensions.

A lot which does not comply with the minimum lot area or dimensional requirements required by this Code at the time of application for development may be occupied by a permitted use in the zone in which the lot is located. Any proposed use of the lot must comply with all other applicable code provisions, including but not limited to setbacks, height limits, and lot coverage requirements. The lot lines of a lot which does not comply with the minimum lot area or dimensional requirements of this Code at the time of application may be adjusted as long as the adjustment does not increase the degree of noncompliance.

[Cross-Reference: See LOC § 50.07.007.2.e.iii for flag lot height requirements.]

General Exceptions to Yard Requirements.

[Ord. No. 2579, Repealed and Replaced, 3-20-2012; Ord. No. 2644, Amended, 4-7-2015; Ord. No. 2732, Amended, 2-21-2017]

Front Yard Setback Averaging.

Except as otherwise provided in this section, the following exception to the front yard requirement for a dwelling or detached garage is authorized for a lot in any zone. If there are lawful dwellings or detached garages (including dwellings or garages deemed lawful nonconforming or through a variance approval) on both abutting lots on the same block face with front yards of less than the required depth for the zone, the front yard for the lot need not exceed the average front yard of the abutting dwellings and/or detached garages. If there is a lawful, nonconforming dwelling or detached garage on one abutting lot on the same block face with a front yard of less than the required depth for the zone, the front yard for the lot need not exceed a depth one-half way between the depth of the abutting lot and the required front yard depth. The front yard setback in the R-5, R-7.5, R-10 or R-15 zone shall not be reduced to less than 15 ft.

Front Porch.

Except as provided in LOC § 50.04.001.2.e.ii(2), a front porch may project up to five ft. into the front yard setback required by the zone or as adjusted in subsection 3.a of this section, provided the front porch is no more than ten ft. in width and, if covered, the roof peak is no greater than 16 ft. in height.

R-DD Yard Setback Adjustment.

For exterior modifications of a single-family detached dwelling in the R-DD zone built before 1960, minimum setbacks may be reduced by two ft. if the modification maintains at least 50% of the exterior walls (measured by sq. ft.) and does not increase height by more than 100%.

Solar Access Yard Setback Adjustment.

In any zone district, side yard setbacks may be reduced by up to 50% and/or the front or rear yard setbacks by up to 25% if the construction of a proposed structure that complies with either the shade point height standard in LOC § 50.06.007.2.c, the allowed shade on a solar feature standard in LOC § 50.06.007.2.d, or the solar balance point standard in LOC § 50.06.007.2.e is not possible without that reduction.

§ 50.04.004 Solar Adjustments.

Exemptions From Solar Design Standard.

[Ord. No. 2579, Repealed and Replaced, 3-20-2012; Ord. No. 2612-A, Amended, 5-21-2013; Ord. No. 2797, Amended, 11-6-2018; Ord. No. 2892, Amended, 6-7-2022]

A development is exempt from the requirements of LOC § 50.06.007.1.c, Solar Design Standard, if the reviewing authority finds the applicant has shown that one or more of the following conditions apply to the site. A development is partially exempt from LOC § 50.06.007.1.c to the extent the reviewing authority finds the applicant has shown that one or more of the following conditions apply to a corresponding portion of the site. If a partial exemption is granted for a given development, the remainder of the development shall comply with the solar access requirements.

Slopes.

The site, or a portion of the site for which the exemption is sought, is sloped 20% or more in a direction greater than 45° east or west of true south, based on a topographic survey by a licensed professional land surveyor.

Off-Site Shade.

The site, or a portion of the site for which the exemption is sought, is within the shadow pattern of off-site features, such as but not limited to structures, topography, or solar-unfriendly vegetation, which will remain after development occurs on the site from which the shade is originating.

Shade from an existing or approved off-site dwelling in a residential zone and from topographic features is assumed to remain after development of the site.

ii.

Shade from an off-site structure in a zone other than a residential zone is assumed to be the shadow pattern of the existing or approved development thereon or the shadow pattern that would result from the largest structure allowed at the closest setback on adjoining land, whether or not that structure now exists.

iii.

Shade from off-site vegetation is assumed to remain after development of the site if: the trees that cause it are situated in a required setback; or they are part of a developed area, public park, or legally reserved open space; or they are in or separated from the developable remainder of a parcel by an undevelopable area or feature; or they are part of landscaping required pursuant to a development permit issued pursuant to this Code.

iv.

Shade from other off-site sources is assumed to be shade that exists or that will be cast by development for which applicable development permits have been approved on the date a complete application for the development is filed.

On-Site Shade.

The site, or a portion of the site for which the exemption is requested, is:

Within the shadow pattern of on-site features such as, but not limited to, structures and topography which will remain after the development occurs; or

ii.

Contains solar-unfriendly trees at least 30 ft. tall and more than six in. in diameter measured four ft. above the ground which have a crown cover over at least 80% of the site or relevant portion. The applicant can show such crown cover exists using a scaled survey or an aerial photograph. If granted, the exemption shall be approved subject to the condition that the applicant preserve at least 50% of the trees that cause the shade that warrants the exemption. The applicant shall file a note on the plat or other documents in the office of the County Recorder binding the applicant to comply with this requirement. The City shall be made a party of any covenant or restriction created to enforce any provision of this section. The covenant or restriction shall not be amended without written City approval.

Adjustments to Solar Design Standard.

[Ord. No. 2579, Repealed and Replaced, 3-20-2012; Ord. No. 2612-A, Amended, 5-21-2013; Ord. No. 2797, Amended, 11-6-2018]

The reviewing authority shall reduce the percentage of lots that must comply with LOC § 50.06.007.1.c, Solar Design Standard, to the minimum extent necessary if it finds the applicant has shown one or more of the following site characteristics apply:

Density and Cost.

If the solar design standard in LOC § 50.06.007.1.c is applied, either the resulting density is less than that proposed, or on-site development costs (e.g. grading, water, storm drainage and sanitary systems and roads) and solar related off-site development costs are at least 5% more per lot than if the standard is not applied. The following conditions, among others, could constrain the design of a development in such a way that compliance with LOC § 50.06.007.1.c would reduce density or increase per lot costs in this matter. The applicant shall show which if any of these or other similar site characteristics apply in an application for a development.

The portion of the site for which the adjustment is sought has a natural grade that is sloped 10% or more and is oriented greater than 45° east or west of true south based on a topographic survey of the site by a professional land surveyor.

ii.

There is a significant natural feature on the site, identified as such in the Comprehensive Plan or development standard, that prevents given streets or lots from being oriented for solar access, and it will exist after the site is developed.

iii.

Existing road patterns must be continued through the site or must terminate on site to comply with applicable road standards, future street plans, or public road plans in a way that prevents given streets or lots in the development from being oriented for solar access.

iv.

An existing public easement or right-of-way prevents given streets or lots in the development from being oriented for solar access.

Development Amenities.

If the solar design standard in LOC § 50.06.007.1.c applies to a given lot or lots, significant development amenities that would otherwise benefit the lot(s) will be lost or impaired. Evidence that a significant diminution in the market value of the lot(s) would result from having the lot(s) comply with the solar access requirement is relevant to whether a significant development amenity is lost or impaired.

Existing Shade.

Solar-unfriendly trees at least 30 ft. tall and more than six in. in diameter measured four ft. above the ground have a crown cover over at least 80% of the lot and at least 50% of the crown cover will remain after development of the lot. The applicant can show such crown cover exists using a scaled survey of solar-unfriendly trees on the site or using an aerial photograph.

Shade from solar-unfriendly trees is assumed to remain if: the trees are situated in a required setback; or they are part of an existing or proposed park, open space, or recreational amenity; or they are separated from the developable remainder of their parcel by an undevelopable area or feature; or they are part of landscaping required pursuant to LOC § 50.06.004, Site Design; and they do not need to be removed for a driveway or other development.

ii.

Also, to the extent the shade is caused by on-site trees or off-site trees on land owned by the applicant, it is assumed to remain if the applicant files in the office of the County Recorder a covenant binding the applicant to retain the trees causing the shade on the affected lots.

Exemption From the Maximum Shade Point Height Standard.

[Ord. No. 2579, Repealed and Replaced, 3-20-2012; Ord. No. 2797, Amended, 11-6-2018]

The City Manager shall exempt a proposed structure or solar-unfriendly vegetation from LOC § 50.06.007.2.c, Maximum Shade Point Height Standard, if the applicant shows that one or more of the conditions in this section exist, based on plot plans or plats, corner elevations or other topographical data, shadow patterns, suncharts or photographs, or other substantial evidence submitted by the applicant.

Exempt Lots.

When created, the lot was subject to LOC §§ 50.04.004.1 and 50.04.004.2, LOC § 50.06.007.1.a through 1.d, and was not subject to the provisions of LOC § 50.06.007.1.d, Protection from Future Shade.

Pre-Existing Shade.

The structure or applicable solar-unfriendly vegetation will shade an area that is shaded by one or more of the following:

An existing or approved building or structure;

ii.

A topographic feature;

iii.

A solar-unfriendly tree that will remain after development of the site. It is assumed a tree will remain after development if it:

(1)

Is situated in a required building setback;

(2)

Is part of a developed area or landscaping required by this Code, a public park or landscape strip, or legally reserved open space;

(3)

Is in or separated from the developable remainder of a parcel by an undevelopable area or feature; or

(4)

Is on the applicant’s property and not affected by the development.

A duly executed covenant also can be used to preserve trees causing such shade.

Slope.

The site has an average slope that exceeds 20% in a direction greater than 45° east or west of true south based on a topographic survey by a licensed professional land surveyor.

Insignificant Benefit.

The proposed structure or solar-unfriendly vegetation shades one or more of the following:

An undevelopable area; or

ii.

The wall of an unheated space, such as a typical garage; or

iii.

Less than 20 sq. ft. of south-facing glazing.

Public Improvement.

The proposed structure is a publicly owned improvement.

Adjustments to the Maximum Shade Point Height Standard.

[Ord. No. 2579, Repealed and Replaced, 3-20-2012]

The City Manager shall increase the maximum permitted height of the shade point determined using LOC § 50.06.007.2.c, Maximum Shade Point Height Standard, to the extent it is found that applicant has shown one or more of the following conditions exist, based on plot plans or plats, corner elevations or other topographical data, shadow patterns, suncharts or photographs, or other substantial evidence submitted to the applicant.

Physical Conditions.

Physical conditions preclude development of the site in a manner that complies with LOC § 50.06.007.2.c due to such things as a lot size less than 3,000 sq. ft., unstable or wet soils, or a drainage way, public or private easement, or right-of-way.

Conflict between the Maximum Shade Point Height and Allowed Shade on the Solar Feature Standards.

A proposed structure may be sited to meet the solar balance point standard described in LOC § 50.06.007.2.e if:

When the proposed structure is sited to meet the maximum shade point height standard, its solar feature will potentially be shaded as determined using LOC § 50.06.007.2.c; and

ii.

The application includes a form provided by the City that:

(1)

Releases the applicant from complying with the maximum shade point height standard and agrees that the proposed structure may shade an area otherwise protected by that section; and

(2)

Releases the City from liability for damages resulting from the adjustment; and

(3)

Is signed by the owner(s) of the properties that would be shaded by the proposed structure more than allowed by the provisions of LOC § 50.06.007.2.c, Maximum Shade Point Height Standard;

iii.

Before the City issues a permit for a proposed structure for which an adjustment has been granted pursuant to this subsection 4.b, the applicant shall file the form provided for in subsection 4.b.ii of this section in the office of the County Recorder with the deeds to the affected properties.
