§ 25.71.010 Purpose.

The Old Fort Lake Subarea Zoning (Chapter 25.58 DMC) and Old Fort Lake Design Standards (this chapter) are the official land use regulations guiding development within the Old Fort Lake subarea. These codes are adopted under Chapter 35A.63 RCW and mandated in RCW 36.70A.040 and are consistent with the state's Growth Management Act, the Old Fort Lake subarea plan, and the DuPont comprehensive plan to serve the public health, safety, and welfare; to provide for orderly planned use of land resources; and to further the policies of the subarea plan. This code helps implement the subarea plan, which may be used to help interpret this code but does not itself regulate land uses. All land uses and development activities within the subarea must comply with the applicable requirements of this code.

(Ord. 25-1154 § 5)

§ 25.71.020 Applicability.

This chapter provides the design standards applicable within the Old Fort Lake subarea. The standards within DMC § 25.71.200 are applicable throughout the subarea. The standards within DMC §§ 25.71.300 through 25.71.400 are applicable to nonresidential and commercial uses within the subarea. The standards within DMC § 25.71.500 are applicable to single-family and middle housing uses within the subarea. Uses in the Old Fort Lake subarea are also subject to the zoning, uses and bulk regulations provided in Chapter 25.58 DMC. Where the design standards conflict with provisions in any other section of the DuPont Municipal Code (DMC), these design standards prevail unless otherwise noted. One exception: Where these design standards conflict with applicable wildland-urban interface standards, the wildland-urban interface standards apply.

(Ord. 25-1154 § 5)

§ 25.71.030 How the design standards are applied.

The provisions of this chapter are additional to the underlying zoning regulations in Chapter 25.58 DMC.

(1)

Guidelines use words such as “should” or “is/are recommended,” or “encouraged,” signifying voluntary measures.

(2)

Standards use words such as “shall” and “is/ are required,” signifying mandatory actions. Some standards are easily quantifiable, while others provide a level of discretion to the applicant in how they are complied with. In the latter case, the applicant shall demonstrate to the director, in writing, how the choices made for the development meet the intent of the standard.

(Ord. 25-1154 § 5)

§ 25.71.040 Departures.

(1)

Purpose. A number of specific departure in this Title opportunities to the design standards contained in DMC §§ 25.71.200 through 25.71.400 are provided. Departure opportunities are signaled by the capitalized word DEPARTURE or the → symbol. The purpose is to provide applicants with the option of proposing alternative design treatments, when they can demonstrate to the satisfaction of the director that it is equal to or better than the standard, provided such departures meet the “intent” of the particular standard, and any additional relevant departure criteria.

(2)

Requests for departures are voluntary. This provision allows the flexibility for applicants to propose alternative designs on a voluntary basis.

(3)

Applicability. Departures are available only where noted for specific standards.

(4)

Procedures. Permit applications that include departure requests are reviewed administratively and the approval decision is made by the director.

(5)

Submittal Requirements. The applicant shall submit a description of the requested departure together with the arguments as to how the departure meets the intent or is equivalent or superior to the standard, and meets the approval criteria.

(6)

Approval Criteria. Project applicants shall successfully demonstrate to the director how the proposed departure meets the intent of the standard, and other applicable departure criteria that applies to the specific standard.

(7)

Documentation. The director shall document the reasons for approving all departures within the project application records for the purpose of providing consistency in decision-making by the city.

§ 25.71.230 Streetscape classifications and regulations.

Subsections (1) through (3) of this section provide the regulations for each streetscape type. All streets within the Old Fort Lake subarea shall be designed for vehicle travel speeds of not more than 35 miles per hour.

(1)

Gateway Streetscape. The “Gateway” is intended to be the primary access into and out of the Old Fort Lake subarea. Its locational context also means that it must accommodate the highest number of users than any other street in the subarea. Figure 25.71.230(b) illustrates a streetscape cross-section that integrates bicycle and pedestrian travel modes located behind the curb and landscape buffer to reduce traffic stress for active modes.

Figure 25.71.230(b)

Gateway Streetscape Cross-Section

NOTES:
1.	Different pavement styles shall be used to distinguish the bicycle portion of the path from pedestrian use. The most common technique is to use an asphalt surface for the bicycle lane and concrete for the pedestrian path. Also, the landscaped areas may include lighting and furnishings per the city's public works standards.
2.	Turn lanes may be added when necessary.
3.	A landscaped center median may also be included along some or all segments where a center turn lane is not needed.
4.	Landscape areas shall integrate low impact development techniques (i.e., bioretention facilities, rain gardens, etc.) unless demonstrated as infeasible.
5.	Pedestrian-scaled lighting shall be provided along the shared use paths.

NOTE: Below is a photo example of similar recent shared-use path constructed in Bellevue, WA.

(2)

Arterial Streetscapes. This includes the main roadway that forms a loop around the Old Fort Lake subarea and the golf course. Arterial streetscapes depend on the context of adjacent uses and whether on-street parking is desired. Figure 25.71.230(c) illustrates designs integrating safe bicycle and pedestrian facilities within commercial and residential contexts.

Figure 25.71.230(c)

Arterial Streetscape Cross-Sections

STANDARDS:
1.	For the Arterial loop (around Old Fort Lake), the shared use path shall be located on the inside, so that no crossing of the arterial is needed to complete a full trail loop.
2.	Parallel parking pockets (seven feet wide) may be integrated into the street design, provided the right-of-way is widened sufficient to accommodate such parking pockets (without reducing the width of other streetscape components).
3.	Turn lanes may be added when necessary.
4.	Landscape areas shall integrate low impact development techniques (i.e., bioretention facilities, rain gardens, etc.) unless demonstrated as infeasible.
5.	Special shared-use path provisions:
	a.	Provide clear, coordinated, and safe transitions for pathway users at intersections.
	b.	Provide pedestrian-scaled lighting.
	c.	Provide signage for wayfinding.
	d.	Provide water, garbage, bicycle parking, and dog stations at key intersections and trailheads.

Block Frontage Designation Mapping, General Rules. All development applications shall include a block frontage designation map as part of the land use approval process. The following provisions apply:

(a)

Nonresidential Zones. Nonresidential zones may utilize storefront, secondary, and basic block frontage designations, but the following provisions apply:

(i)

Storefront block frontage designation is required for a minimum of 20 percent of the streets within or bordering the zone.

(ii)

Basic block frontage designation is allowed for up to 20 percent of the streets within or bordering the zone.

(iii)

DEPARTURES → are allowed to relax the above requirements by no more than 50 percent, provided the reviewing authority determines that the block frontage designation plan helps to creates a vibrant pedestrian-friendly mixed-use node that can meet the goals and policies of the Old Fort Lake subarea plan. The percentage of storefront block frontage designations in nonresidential zones may be reduced no less than 10 percent.

(b)

Neighborhood Business Zone. Streets within and bordering the neighborhood business zone are subject to basic block frontage provisions, except the minimum required landscaping buffers between the sidewalk and parking lots is increased to 15 feet.

(c)

Multifamily Development. Multifamily development is subject to the landscape block frontage designation. Exception: Multifamily adjacent to secondary block frontage designations may utilize storefront block frontage designs for leasing and common areas provided they comply with the storefront block frontage standards. Leasing and common areas may occupy ground level storefront block frontage designated area.

(d)

Civic uses, public buildings, and hotels are exempt from the block frontage standards, provided the building and site design meet the following objectives:

(i)

(A)

Appearance. All crosswalks shall contain contrasting material (such as concrete) and/or patterns (such as stamped asphalt), excluding painted surfaces.

(B)

Raised Crosswalks (Speed Tables). On sites larger than one acre, all crosswalks near major building entrances, parking garage entries, vehicular entries to the site, and other high-traffic areas shall be vertically raised to sidewalk level. The purpose of raised crosswalks is to provide a continuous walking or rolling surface, increase the visibility of pedestrians, and slow the speed of vehicular traffic. This requirement does not apply to crosswalks crossing public roadways.

(C)

DEPARTURES. Departures will be considered where other crosswalk options are determined to address pedestrian visibility and overall safety.

(iv)

Pedestrian Walkways Through Parking Lots. Developments with 50 or more parking spaces shall include specially marked or paved walkways through parking areas.

(v)

Walkway Design.

(A)

All internal walkways shall have a minimum six-foot-wide unobstructed walking surface, except where wider walkways are prescribed elsewhere in this chapter or where the applicable uses and context dictate wider walkways.

(B)

Where an internal walkway is adjacent to perpendicular or angled parking, wheel stops are required to prevent encroachment of parked vehicles over the walkway. In lieu of wheel stops, an extra two feet of walkway width shall be provided.

(C)

Internal walkways shall be separated from structures by at least three feet for landscaping except where the adjacent building facade meets the storefront block frontage standards per DMC § 25.71.310.

(D)

DEPARTURES will be considered where other landscaping and/or facade design treatments to provide attractive walkways are proposed. Examples include, but are not limited to, sculptural, mosaic, bas-relief artwork, or other decorative treatments that meet the purpose. Figure 25.71.320(i) provides one example.

Figure 25.71.320(i)

Standards for Internal Walkways Adjacent to Buildings

Internal walkways adjacent to building walls that do not meet storefront facade standards shall provide at least three feet of landscaping to enhance the character of the walkway. The reviewing authority will consider alternative treatments, such as decorative walls (right example).

(E)

Where walkways are between a parking lot and a multi-tenant commercial building which is 100 feet or more long, walkways shall feature a 12-foot-wide sidewalk with the following features:

Eight feet minimum unobstructed width.

Trees placed at an average of 50 feet on-center and placed in grates or in planting strips as set forth in subsection (6)(c)(v)(E)(3) of this section.

DEPARTURE: Breaks in the tree coverage will be considered near building entries to enhance visibility.

Planting strips may be used between any vehicle access or parking area and the walkway; provided, that the trees required above are included, the walkway meets the applicable width standards herein, and the combined walkway and planting strip is at least 12 feet wide.

(7)

Vehicular Circulation and Parking. The standards herein supplement the provisions of the DuPont public works standards. Where there is a conflict, the provisions herein apply, except that the city engineer may override this requirement and apply the public works standard for a driveway if the public works director finds that a failure to apply the public works standards will result in a threat to public safety.

(a)

Intent.

(i)

To create a safe, convenient, and efficient network for vehicle circulation and parking.

(ii)

To enhance the visual character of interior access roads.

(iii)

To minimize conflicts with pedestrian circulation and activity.

(b)

Driveways. Driveways shall meet the standards of the DuPont Public Works Standards Manual, including, but not limited to, standards for intersection spacing, distance from crosswalks, and width.

(c)

Parking Entry Location. Parking lot and parking garage entries shall provide vehicular access in the following order of preference:

(i)

Alleys.

(ii)

Basic block frontage streets.

(iii)

Landscaped block frontage streets.

(iv)

Secondary block frontage streets. See related standards for parking location in DMC § 25.71.310, Block frontage standards, and off-street parking quantities in DMC § 25.71.280.

(d)

Garage and Service Area Entries and Pedestrian Safety.

(i)

Parking garage entries and service area entries shall be well-integrated into the design of the building and shall not dominate the streetscape. They should be designed and sited to complement, not subordinate, the pedestrian entry.

(ii)

Where vehicles enter and exit a parking garage or service area across a sidewalk or internal walkway, direct visibility between pedestrians and motorists shall be provided. Treatments shall include setback entries, cropped wall corners, wall openings, or other treatments to enhance safety and visibility. Treatments should also include pavement markings or changes in pavement materials. Mirrors and electronic visual/audio warnings alone are not acceptable methods of visibility.

(iii)

Parking garage entries are encouraged to have flat driveways behind the sidewalk for the length of at least one vehicle in order to enhance visibility between pedestrians and motorists exiting the garage. Steeply sloping driveways immediately adjacent to a sidewalk or internal walkway require greater application of visibility treatments described in subsection (7)(d)(ii) of this section.

(iv)

Garage entry doors and gates, if provided, shall be at least 50 percent transparent between the bottom and top of the door or gate in order to enhance the safety of garage users.

(8)

To minimize adverse visual, odor, fumes, and noise impacts of mechanical equipment, utility cabinets and other service areas.

(ii)

To provide adequate, durable, well-maintained, and accessible service and equipment areas.

(iii)

To protect residential uses and adjacent properties from impacts due to location and utilization of service areas.

(b)

Location of Ground-Level Service Areas and Mechanical Equipment. Ground-level building service areas and mechanical equipment include loading docks, trash collection and compactors, dumpster areas, storage tanks, electrical panels, HVAC equipment, and other utility equipment. Any elements located outside the building envelope at ground level, the following standards apply:

(i)

Service areas shall be located for convenient service access while avoiding negative visual, auditory, olfactory, or physical impacts on the streetscape environment and adjacent residentially zoned properties.

(ii)

Service areas shall not be visible from the sidewalk and adjacent properties. Where the director finds that the only option for locating a service area is an area visible from a public right-of-way, resident/customer parking area, internal walkway, or pedestrian area, or from an adjacent property, the service area shall be screened with the structural and landscaping screening measures provided in subsection (8)(c)(iii) of this section.

(iii)

Service areas for multiple users or tenants shall be co-located or consolidated to the extent practical.

(iv)

Service areas shall be sited for alley access if available. Service elements accessible from an alley are exempt from the screening requirements of this section.

(v)

Trash collection areas shall include roofs or overhead weather protection and shall meet required stormwater standards. Drainage shall be designed to meet applicable National Pollution Discharge Elimination System (NPDES) standards.

(vi)

Exterior loading areas for commercial uses shall not be located within 20 feet of a residentially zoned property.

DEPARTURE: Exterior commercial loading areas are exempt from this standard if the reviewing authority finds such a restriction does not allow feasible development and alternative design measures can successfully mitigate potential negative impacts. For example, areas and drives may be required to be separated from the residential lot by a masonry wall at least eight feet high.

(vii)

Other provisions of this section notwithstanding, service areas used by residents shall be located to avoid entrapment areas and other conditions where personal security is potentially a problem. Pedestrian-scaled lighting or other measures may be needed to enhance security.

(viii)

Noise-producing mechanical equipment, such as fans, heat pumps, etc., shall be located and/or shielded to minimize sounds and reduce impacts to adjacent dwelling units.

(ix)

Dumpster storage areas shall be provided for all development, located on site and not in the public right-of-way, and sized to accommodate the minimum dumpster sizes (see DMC § 25.100.050).

(c)

Screening of Ground-Level Service Areas and Mechanical Equipment. Where screening of ground level service areas is required, the following applies:

(i)

Structural enclosures shall be constructed of masonry, heavy-gauge metal, heavy timber, or other decay-resistant material that is also used with the architecture of the main building. Alternative materials other than those used for the main building are permitted if the finishes are similar in color and texture, or if the proposed enclosure materials are more durable than those for the main structure. The walls shall be sufficient to provide full screening from the affected roadway, pedestrian areas, or adjacent use, but shall be no greater than seven feet tall. The enclosure may use overlapping walls as a screening method. See Figure 25.71.320(j).

(ii)

Gates shall be made of heavy-gauge, sight-obscuring material. Chain link or chain link with slats is not an acceptable material for enclosures or gates.

(iii)

Where the interior of a service enclosure is visible from surrounding streets, walkways, or residential units, an opaque or semiopaque horizontal cover or screen shall be used to mitigate unsightly views. The horizontal screen/ cover should be integrated into the enclosure design (in terms of materials and/or design).

(iv)

Trash collection points shall be located and configured so that the enclosure gate swing does not obstruct pedestrian or vehicle traffic or does not require that a hauling truck project into any public right-of-way. Screening elements shall allow for efficient service delivery and removal operations.

(v)

The service area shall be paved.

(vi)

The sides and rear of service enclosures shall be screened with landscaping at least five feet wide in locations visible from the street, parking lots, and walkways to soften views of the screening element and add visual interest. Plants shall be arranged with a minimum of 50 percent coverage at time of installation and be able to grow to fully screen or shield the equipment within three years.

(vii)

DEPARTURES will be considered, provided the enclosure and landscaping treatment meet the purpose of the standards and add visual interest to site users.

Figure 25.71.320(j)

Acceptable Trash Screening Enclosures

All examples use durable and attractive enclosures with trees and shrubs to soften views of the enclosures from the side. Images C and D use a trellis and weather protection structure on top – a desirable feature particularly where the tops of the enclosures are visible from surrounding buildings, streets, and walkways (due to topography or building heights).

(d)

Utility Meters, Electrical Conduit, and Other Service Utility Apparatus. These elements shall be located and/or designed to minimize their visibility to the public. Project designers are strongly encouraged to coordinate with applicable service providers early in the design process to determine the best approach in meeting these standards. If such elements are mounted in a location visible from the street, internal walkway, common outdoor recreation area, or shared auto courtyards, they shall be screened with vegetation and/or integrated into the building’s architecture.

Figure 25.71.320(k)

Utility Meter Location and Screening – Good and Bad Examples

Place utility meters in less visible locations. Images A and C are successfully tucked away in a less visible location and/or screened by vegetation. Images B and D are poorly executed and would not be permitted in such visible locations. Such meters shall be coordinated and better integrated with the architecture of the building.

(e)

Roof-Mounted Mechanical Equipment.

(i)

All rooftop mechanical equipment, including air conditioners, heaters, vents, and similar equipment shall be fully screened from public view at the street level and from rooftop residential amenity spaces. Screening shall be located so as not to interfere with operation of the equipment.

Exception: Roof-mounted wind turbines, solar energy and photovoltaic systems, and rainwater reuse systems do not require screening.

(ii)

For rooftop equipment, all screening devices shall be well integrated into the architectural design through such elements as parapet walls, false roofs, roof wells, clerestories, or equipment rooms. Screening walls or unit-mounted screening is allowed but less desirable. Wood shall not be used for screens or enclosures. Louvered designs are acceptable if consistent with building design style.

(iii)

The screening materials shall be of material requiring minimal maintenance and shall be as high as the equipment being screened.

(iv)

Noise producing mechanical equipment, such as fans, heat pumps, etc., shall be located and/or shielded to minimize sounds and reduce impacts to adjacent dwelling units.

Figure 25.71.320(l)

Examples of How to Screen Roof-Mounted Mechanical Equipment

The left illustration shows how rooftop mechanical equipment can be located and screened effectively. The right image shows effective location and screening, including side walls and a trellis to screen views from taller surrounding buildings.

(10)

Landscaping.

(a)

Intent.

(i)

To emphasize landscaping as one of the character-defining features of the Old Fort Lake subarea.

(ii)

To accommodate flexibility for the total amount of landscaped area for mixed-use and multifamily areas.

(b)

Wildland-Urban Interface Standards. Old Fort Lake subarea is within defined wildland-urban interface areas and is thus subject to special landscaping standards for such areas. Where these landscaping standards conflict with applicable wildland-urban interface standards, the wildland-urban interface standards apply.

(c)

Standards. Developments are subject to the landscaping provisions of Chapter 25.90 DMC, with the following exceptions:

(i)

Minimum landscaped area for multifamily areas where more than 50 percent of the off-street parking is contained within or under buildings shall be 25 percent.

(ii)

The following landscaped types and credits may be used within the interior landscaping of multifamily developments:

(A)

Ground level planting beds qualify as landscaped surfaces at a 100 percent rate.

(B)

Green Roof. Green roofs qualify as a landscaped surface at a 50 percent rate (i.e., two square feet of green roof qualifies as one square foot of landscaped area) provided they comply with wildland-urban interface standards. Green roof areas with soil depths greater than 12 inches and planned to support large shrubs and trees qualify as a landscaped surface at a 100 percent rate.

(d)

Other landscaping standards are set forth in the following sections:

(i)

Block frontage standards of DMC § 25.71.310.

Most of the site planning standards of DMC § 25.71.320.

(iii)

Blank wall treatment standards of DMC § 25.71.470.

(Ord. 25-1154 § 5)

§ 25.71.400 Building design.

(Ord. 25-1154 § 5)

§ 25.71.410 Intent.

This section provides standards to promote buildings with an architectural character that reflects the envisioned Old Fort Lake aesthetic and is based on human-scaled design details, durable high-quality materials, and responds uniquely to the site's context.

(Ord. 25-1154 § 5)

§ 25.71.420 Applicability.

These building design standards are applicable to all nonresidential and multifamily developments in the Old Fort Lake subarea, except where specifically exempted.

(Ord. 25-1154 § 5)

§ 25.71.430 Building character and variety.

(1)

Intent.

(a)

To avoid generic, corporate architectural design that degrades the character and identity of DuPont.

(b)

To avoid monotonous repetition of the same building forms, materials, and colors in larger developments.

(2)

Corporate Architecture Prohibited. Architecture that is defined predominately by corporate identity features and is difficult to adapt to other uses is prohibited. For example, some franchise convenience uses have very specific architectural features (such as a distinctive roofline design that functions as a sign) that reinforce their identity. As tenants change in these types of buildings, these corporate identity features can negatively impact the character of the area and identity of new tenants. These features can also be very expensive to reconfigure and adapt to new uses.

(3)

Building Design Variety. Buildings in multi-building developments shall visibly vary in at least one significant aspect so that they are clearly not identical as viewed from public streets. Aspects can include forms, massing and the composition and articulation of exterior building materials, fenestration patterns, building entries, weather protection features, and rooflines.

(Ord. 25-1154 § 5)

§ 25.71.440 Building massing and articulation.

(1)

Intent. This section contains standards that affect the massing of buildings through facade design articulation, facade width, and roofline design. The purpose of this section is:

(a)

To employ architectural elements (like windows, balconies, entries, etc.) that create a complementary pattern or rhythm, dividing large buildings into smaller identifiable pieces.

(b)

To integrate substantial articulated/modulated features on large buildings to break up the massing and add visual interest.

(2)

Exemptions. Buildings with less than 50 horizontal feet of facade are exempt from the standards in this section. Civic and public buildings are exempted from the requirements of this section, provided they employ architectural elements that create a complementary pattern or rhythm, design details, and visual interest consistent with the intent.

(3)

Facade Articulation. Facade articulation to create a human-scaled pattern is required for streetfacing building facades and other building elevations facing parks or the golf course, containing primary building entrances, and adjacent to lower intensity zones.

(a)

For nonresidential buildings at least three articulation features shall be employed at intervals no greater than 40 feet in the commercial and entertainment zone, and 60 feet in the neighborhood business zone.

(b)

Multifamily buildings in all applicable zones shall employ at least three articulation features at intervals that relate to the location/size of individual units within the building (or no more than every 50 feet).

(4)

Articulation features to meet the standards of subsection (3) of this section include:

(a)

Use of window patterns and/or entries that reinforce an articulation pattern.

(b)

Use of awnings or similar weather protection features (not applicable to residential buildings).

(c)

Use of vertical piers/columns.

(d)

Change in roofline with a difference in height, slope or pitch, direction, or shape (such as towers or dormers).

(e)

Change in building material or siding style.

(f)

Use of vertical building modulation of at least 12 inches in depth if tied to a change in roofline per subsection (4)(d) of this section or a change in building material, siding style, or color. On residential buildings balconies may be used to qualify for this option if they are recessed or projected from the facade by at least 18 inches. Juliet balconies or other balconies that appear to be tacked on to the facade will not qualify for this option unless they employ high quality materials and effectively meet the purpose of the standards.

(g)

Other design techniques that effectively break up the massing of structures and add visual interest.

(5)

DEPARTURES: Other articulation features may be approved, provided they meet the purpose of the standards and the design criteria set forth in subsection (5)(a) of this section.

Figure 25.71.440(a)

Nonresidential Articulation Examples

The left image uses window patterns, weather protection elements, and roofline modulation. The photo example to the right also includes window patterns and weather protection along with a change in masonry texture and color to articulate the facade. The lower example illustrates how a multitenant retail building can successfully be articulated (windows, weather protection, vertical building modulation, and roofline changes).

Figure 25.71.440(c)

Multifamily Roofline Articulation Examples

Below Image A uses a combination of vertical building modulation, window patterns, material changes, and roofline modulation. Image B is unacceptable.

Roofline modulation qualifies as an articulation feature when combined with vertical building modulation techniques.

The left building illustrates a pitched roof example, and the right building illustrates a flat roof example.

(a)

Departure Criteria Associated With Articulation Standards. The following criteria will be considered in determining whether the proposed articulation treatment meets the intent:

(i)

The type and width of the proposed articulation treatment and how effective it is in meeting the purpose given the building’s context.

(ii)

The applicable block frontage designation. Basic block frontages warrant more flexibility than block frontages designated as secondary or landscaped.

(iii)

The size and width of the building. Smaller buildings warrant greater flexibility than larger buildings.

(iv)

The quality of facade materials in concert with doors, windows, and other facade features and their ability to add visual interest to the street from a pedestrian scale and more distant observable scales.

(6)

Maximum Facade Width. Street-facing building facades and other building elevations facing lower intensity zone edge must include at least one of the following features to break up the massing of the building and add visual interest. This standard applies to applicable building elevations wider than 120 feet (wider than 200 feet in the neighborhood business zone).

(a)

Provide vertical building modulation at least six feet deep and 15 feet wide. For multi-story buildings, the modulation must extend through at least one-half of the building floors.

(b)

Use of a contrasting vertical modulated design component featuring all of the following:

(i)

Utilizes a change in building materials that effectively contrast from the rest of the facade.

(ii)

Component is modulated vertically from the rest of the facade by an average of six inches.

(c)

Facade employs building walls with contrasting articulation that make it appear like multiple distinct buildings. To qualify for this option, these contrasting facades must employ all of the following:

(i)

Different building materials and/or configuration of building materials.

(ii)

Contrasting window design (sizes or configurations).

(d)

DEPARTURES to subsections (6)(a) through (6)(c) of this section will be considered provided the design meets the intent of the standards. Supplemental consideration for approving alternative designs:

(i)

Width of the Facade. The larger the facade, the more substantial articulation/modulation features need to be.

(ii)

Block Frontage Designation. Storefront designated block frontages warrant the most scrutiny while undesignated streets warrant more flexibility.

(iii)

The type of articulation treatment and how effective it is in meeting the purpose given the building’s context.

Figure 25.71.440(d) Illustrating Maximum Facade Width Standards and Good and Bad Examples
Less than 120 feet wide: Meets standard.	More than 120 feet wide: Does not meet standard.
Building incorporates a courtyard along the facade (technique #1 noted above) to effectively break it up into smaller components: Meets standard.
The left building uses technique # 1 (vertical building modulation at least six feet deep and 15 feet wide). The right building uses technique #2 (contrasting vertical modulated design component). Both examples are effective in breaking up the perceived scale of the building and adding visual interest.

(Ord. 25-1154 § 5)

§ 25.71.460 Building materials.

(1)

Intent.

(a)

To encourage the use of durable, high quality building materials that minimize maintenance cost and provide visual interest from all observable vantage points.

(b)

To promote the use of a distinctive mix of materials that helps to articulate facades and lends a sense of depth and richness to the buildings.

(c)

To place the highest priority on the first floor in the quality and detailing of materials at the pedestrian scale.

(2)

Wildland-Urban Interface Standards. Old Fort Lake subarea is within defined wildland-urban interface (WUI) areas and is thus subject to special development standards for such areas. Where these building materials standards conflict with applicable wildland-urban interface standards, the wildland-urban interface standards apply.

(3)

Quality Building Materials.

(a)

Applicants shall use high quality durable materials. This is most important for the base of buildings, particularly for commercial and neighborhood business buildings where the facade is sited close to sidewalks.

(b)

Prohibited exterior building materials:

Fiberglass.

(ii)

Vinyl and plastic siding.

(iii)

Plywood.

(iv)

T-111 siding.

(v)

Exterior insulation and finish system (EIFS).

(c)

The use of sustainably harvested, salvaged, recycled, or reused products is encouraged wherever possible.

(4)

Special Conditions and Limitations for Concrete Block (Also Known as Concrete Masonry Unit or CMU).

(a)

Concrete block may be used as a cladding material for single story nonresidential buildings or on the ground floor of any multi-story building provided it is incorporated with other permitted materials and/or incorporates a combination of textures and/or colors to add visual interest. For example, combining split or rock-facade units with smooth blocks can create distinctive patterns. Figure 25.71.460(a) illustrates acceptable concrete block use/designs.

(b)

DEPARTURES will be considered, provided the material’s integration and overall facade composition meets the intent of the standards.

Figure 25.71.460(a)

Acceptable Concrete Block Use and Design

Building A uses alternating rows of concrete block and brick as an effective and contrasting accent material for its podium structure. Building B uses CMU as the primary cladding material for the ground level. Note the use of split-facade CMUs above each of the awnings and coupled with the use of smooth-facade CMUs on the vertical columns (which employ black accent tiles for added interest).

(5)

Special Conditions and Limitations for Metal Siding. Metal siding may be used as a secondary cladding material (no more than 35 percent of the cladding for the front facade and no more than 50 percent for other buildings elevations) if it is incorporated with other permitted materials and complies with the following standards:

(a)

Metal siding shall not extend lower than two feet above grade. Masonry, concrete, or other durable material shall be incorporated between the metal siding and the ground plane.

(b)

Metal siding shall be factory finished with a matte, nonreflective surface.

(c)

Metal siding shall feature visible corner molding and trim.

(d)

Use of at least two colors is encouraged but not required.

(e)

DEPARTURES will be considered, provided the material’s integration and overall facade composition meets the intent of the standards.

Figure 25.71.460(b)

Acceptable Metal Siding Examples

The buildings in Images A and B integrate a range of metal siding with masonry and other materials.

(6)

Special Conditions and Limitations for Cementitious Wall Board Paneling/Siding. Such material may be used, provided it meets the following provisions:

(a)

No more than 30 percent of the facade’s cladding and 40 percent of other building elevations’ cladding may be one texture and color of cement board.

(b)

Cement board paneling/siding may not be used on the ground floor of nonresidential buildings where adjacent to a sidewalk or other internal walkway.

(c)

Where cement board paneling/siding is used, the design shall integrate a mix of colors and/ or textures that are articulated consistent with windows, balconies, and modulated building surfaces and are balanced with facade details that add visual interest from the ground level and adjacent buildings.

(d)

DEPARTURES will be considered, provided the material’s integration and overall facade composition meets the intent of the standards.

Figure 25.71.460(c)

Acceptable and Unacceptable Cementitious Wall Board Examples

The building on the left uses cement board in different textures and colors to help articulate the facade. The white color replicates the board and batten style in the left image and green color in the middle image effectively replicates horizontal wood siding. The wall board panels covering a large area in a single color as in right image would not meet the purpose of the standards.

(Ord. 25-1154 § 5)

§ 25.71.470 Blank wall treatment.

(1)

Intent.

(a)

To avoid untreated blank walls.

(b)

To retain and enhance the character of Old Fort Lake's streetscapes.

(2)

(a)

Display windows at least 16 inches of depth to allow for changeable displays. Tack on display cases do not qualify as a blank wall treatment.

(b)

Landscape planting bed at least five feet wide or a raised planter bed at least two feet high and three feet wide in front of the wall with planting materials that are sufficient to screen at least 60 percent of the wall's surface within three years.

(c)

Installing a vertical trellis or “green wall” in front of the wall with climbing vines or plant materials. The method shall be sufficient to screen at least 60 percent of the wall surface within three years. This option requires an irrigation and maintenance plan sufficient to maintain healthy plants for the life of the building.

(d)

Installing a noncommercial mural or other permanent art feature, such as metal work or mosaics, subject to final approval by the director.

(e)

Building detailing that adds visual interest at a pedestrian scale such as belt courses of masonry, decorative tile work, or accent lighting. Such detailing shall use a variety of surfaces; monotonous designs will not meet the purpose of the standards.
