B.
Design and Operation Standards.
1.
Manufactured home parks must meet the following design standards:
a.
All manufactured home parks require site plan review.
b.
The perimeter yard of a manufactured home park requires a buffer area of 15 feet at the furthest point in the required setback from the abutting lot line, and must contain the following:
(1)
A mix of shade and evergreen trees planted at an average of one tree for every 50 linear feet of yard width. These shade and evergreen trees may be clustered to allow for access points or to maximize the screening effect, conditioned on approval of the landscape plan.
(2)
Two ornamental trees may be substituted for one shade tree for up to 25% of required trees.
(3)
Shrubs must be planted and space sufficiently to form a continuous linear hedgerow at plant maturity.
(4)
The remainder of the buffer area must be planted with low ground cover, seed, or sod.
2.
Manufactured home sites within parks must meet the following design standards:
a.
The boundaries of each manufactured home site must be clearly marked.
b.
There must be at least 15 feet between the sides of manufactured homes. Bay windows, porches, canopies or other projections are considered sides or ends of a mobile home when determining these requirements. Such projections, such as porches and canopies, must be constructed of fireproof material that meets the requirements of the Building Code.
c.
Each manufactured home site must have a concrete slab or runway for the manufactured home to set on, and be of a size large enough to accommodate a manufactured home in such a fashion that the concrete will extend at least one inch around the walls of the manufactured home on all sides.
d.
There must be a concrete slab alongside of each manufactured home site of at least 12 feet by 30 feet to be used as a parking space for the occupants of the manufactured home. If a canopy is to be used over the area designated as car storage, it must be of fire-resistant material and is allowed only at the rear end of each carport area.
e.
All manufactured homes must be designed with skirting that is constructed of noncombustible or fire-resistant material that meets the requirements of the building code.
f.
The front entry of a manufactured home should be a dominant feature of a manufactured home, using features such as porches, raised steps and stoops with roof overhangs, or decorative railings.
17.04.050 R-3C and R-4C District design standards.
[Amended 12-11-2024 by Ord. No. 2024-522; 9-11-2019 by Ord. No. 2019-363]
In addition to the use standards for dwelling types located in Chapter 17.08, the following design standards apply to the R-3C and R-4C Districts. The standards below are applicable to construction of a new dwelling, construction of a new garage and/or carport, and/or an addition to an existing dwelling that exceeds 25% of the building footprint of the structure as it was on the effective date of this Ordinance. The R-3C and R-4C Districts are Special Purpose Districts as defined in Section 17.02.030.
A.
Building massing and orientation.
1.
The scale of new construction must maintain compatibility with adjacent homes and the overall character of the surrounding area.
2.
Architectural elements within the design must be in proportion to the overall structure.
3.
The scale of additions to existing homes must maintain compatibility with the size of the existing structure and its architectural elements, as well as with the size of adjacent homes and the overall character of the surrounding area.
4.
Foundation height must maintain compatibility with adjacent homes, provided adequate drainage can be achieved.
5.
Dwellings must be oriented toward the residential street and must connect to the sidewalk via walkways perpendicular to the street.
B.
Facade design.
1.
All facades that face a street must have articulation in the form of windows, doors, or other significant architectural features that are projected or recessed to create shadow and visual interest.
2.
The number and size of facade articulations must be scaled to the size of the facade to balance a home's compatibility within the neighborhood with its own unique character.
3.
Additions to existing homes must continue the architectural vocabulary established by the original home and must be informed by the overall character of the surrounding area.
4.
Front porches are encouraged, to add interest and scale to the front of a home. Where provided, porches must maintain compatibility with adjacent homes.
5.
The front entry to a home must be a prominent feature and must be located on the front facade.
C.
Fenestration.
1.
The design of a home's fenestration must reflect a consistent rhythm, repeating elements or groups of elements in a consistent manner across a home's story and between stories. Individual elements may vary in size but must relate to each other proportionally.
2.
Elements of fenestration must relate to each other visually by sharing design features such as vertical or horizontal alignment, depth, or ornamentation such as muntins, mullions, sills, trim, lintels, etc.
3.
Facades facing onto immediately adjacent properties must design their fenestration to respect the privacy of neighbors. This may be addressed through the height, size, or proportion of windows, the exclusion of balconies, and the use of opaque or translucent materials.
D.
Roof form.
1.
Roof forms must be varied through a combination of structural articulations, such as gables, hips, valleys, ridges, and saddles, that complement the roof form of adjacent homes.
2.
Roof pitch should be consistent for all sloped roof faces and should maintain compatibility with adjacent homes and the overall character of the surrounding area.
3.
Definition is encouraged, through integration of architectural features such as dormers, eyebrows, chimneys, and deep eaves, which create shadows across the facade of a structure and create visual interest.
E.
Building materials. Building materials for new homes or additions to existing homes must maintain compatibility with adjacent homes and the overall character of the surrounding area.
1.
Primary building materials. Primary building materials are the dominant component of a home's exterior walls, composing 75% to 90% of each building face.
a.
No more than two primary building materials are permitted for new homes, not including foundation
b.
For additions to existing homes, no more than two primary building materials are permitted, provided that the total number of primary building materials for the overall structure, including addition, is not more than two.
c.
Color, texture, or finish changes within any category of materials count as separate primary building materials.
e.
Building materials not listed above may be considered on a case-by-case basis and will be evaluated based upon such factors as durability, maintenance, architectural or design intent, and neighborhood context.
2.
Accent materials. Accent materials are secondary components of a home's exterior walls, typically used to provide architectural detail or visual interest to a facade. Accent materials may not compose more than 25% of each building face.
a.
For new construction and additions to existing homes, if one primary building material is used (not including a foundation), a minimum of two but no more than three accent materials are permitted for the overall structure, including any addition.
b.
For new construction and additions to existing homes, if two primary building materials are used (not including a foundation), a minimum of one but no more than two accent materials are permitted for the overall structure, including any addition.
c.
Color, texture, or finish changes within any category of materials count as separate accent materials.
e.
Accent materials not listed above may be considered on a case-by-case basis and will be evaluated based upon such factors as durability, maintenance, architectural or design intent, and neighborhood context.
3.
Roofing materials.
a.
Roofing materials should complement the architectural style of a home.
b.
A consistent application of one roofing material is required for all roof areas visible from the right-of-way or any neighboring property.
c.
Color, texture, or finish changes within any category of materials listed below count as separate roofing materials.
e.
Roofing materials not listed above will be considered on a case-by-case basis and will be evaluated based upon such factors as durability, maintenance, architectural or design intent, and neighborhood context.
4.
Application of building materials.
a.
Building materials should be consistently applied on all exterior faces of new homes. Elevations of different materials or colors are not permitted, such as brick or stone front facades with vinyl siding on side and rear elevations.
b.
Visual balance should be maintained on each face of a structure. For both new construction and additions to existing homes, if multiple primary building materials are used on the overall structure, those that appear heavier, or that carry more visual weight, should be placed toward the bottom of a structure, with materials that appear lighter placed above.
c.
Frequent or irrational changes in building materials should be avoided. Change of materials should occur with prominent architectural features or changes in wall plane.
d.
Where materials change with a change in wall plane, the material change should occur on the inside corner, not the outside edge.
