(A) NuLu Review Overlay District objective.
(1) The NuLu Review Overlay District was created in 2015 to help enhance the appearance, sustainability, and economic vitality of the NuLu area - one of the community's burgeoning mixed-use areas. The boundaries of the District are provided in Appendix H of this chapter. The District's permit review process is administered by the Louisville Metro Office of Planning, with input from a citizen-review panel known as the NuLu Review Overlay District Committee, as prescribed by KRS 82.670. Within the Office of Planning, the Urban Design Administrator and staff administers, manages, and conducts the architectural review process.
(2) The guidelines are not intended to discourage development or to dictate specific architectural design or style, but to encourage development that contributes to the overall design quality and sustainability of the District. The guidelines address construction and other external changes to buildings and properties located in the District.
(3) They are intended to promote compatibility of new development with existing land use and design features, to enhance NuLu's visual quality, to reinforce the area's focus on sustainability, to preserve the area's mixed-use character with a pedestrian friendly environment, and to strengthen the economic vitality of the area by encouraging new investment in business, residential, and commercial development in appropriate locations.
(4) All development proposals within the District shall comply with applicable guidelines; however a proposal that does not conform to one or more specific guidelines may be approved if it is determined that the proposal is in conformance with the intent and objectives of the District. In the event a guideline is not met, the Urban Design Administrator or the Committee may impose a condition(s) of approval on a permit that mitigates the deficiency, such as a condition to exceed the minimum requirements of another guideline or to meet a guideline that is not mandatorily required.
(5) The principles and guidelines of the District expand upon the requirements of the Land Development Code as necessary to achieve the objectives of these facets of urban design in recognition of a project's specific location.
NULU REVIEW OVERLAY DISTRICT
(B) Building design guidelines. The buildings in the NuLu Review Overlay District are not only picturesque but also have strong historic character. New structures should have a "contextual fit" and reinforce the existing pattern of individual storefronts extending throughout the District. Contextual design elements include building setbacks, building heights, building form, rhythm of openings, rhythm of horizontal building lines, color, materials, texture, adjacent building styles, and building details should be respected in new projects. The Urban Design Administrator and Staff can assist applicants to develop designs that adaptively reuse these structures to meet the needs of new businesses and services.
(1) Existing buildings are strongly encouraged to be sustainably renovated and reused.
(2) A new building or street facing addition shall be a minimum of three stories in height if located in a downtown or urban center neighborhood form district and a minimum of two stories in height if located in another type of form district (as shown on the official form district map associated with the land development code).
(3) A new building or addition may be up to eight stories in height if located in a downtown form district, six stories in height if located in an urban center neighborhood form district, and up to four stories in height in another type of form district (as shown on the official form district map associated with the land development code). If a building includes structured parking, an additional story is permitted if at least one story of the building is 50% or more parking.
(4) The ground and second stories of a new building or addition shall be located at the front property line, unless there is deeper historic setback on the block that is more appropriate. Building sites shall provide side yards wide enough to allow for maintenance of the building unless common party walls are provided on the lot line.
(5) A new building or addition that is greater than three stories in height shall be designed to be compatible with any existing historic building on the same or a contiguous lot. Upper stories may need to be stepped back. The location should be considered carefully in order to avoid blocking any historic building's primary elevation(s). New construction should be placed away from or at the side or rear of historic buildings and must avoid obscuring, damaging, or destroying character-defining features of these buildings.
(6) A new building on Main, Market, or Jefferson Street should be designed for mixed-use, with the potential and opportunity for nonresidential uses on the ground floor.
(7) A new building on Hancock or Clay Street should be built to a neighborhood-scale and designed for mixed-use.
(8) A new building or addition shall be designed in a manner that is compatible in scale with neighboring buildings. In cases in which the development site includes more than a quarter of the block, several buildings are encouraged rather than a single larger building. Larger buildings should utilize design features to reduce monotony and massing, such as insets, changes in material, and varying heights. Variations on the facade plane such as inset entries, building piers, and other details can assist in providing relief to long expanses of building wall.
(9) Buildings shall be "pedestrian-friendly" in design. Building facade elements that promote a pedestrian-friendly environment include: building to the front property line, large storefront window openings at the ground floor, awnings, canopies, and lighting.
(10) Primary building entrances shall face the street and be accentuated. Such entrances should be designed so that they are easily identified and not confused with secondary entrances or entrances not intended for use by the general public. Art and higher levels of architectural detail can help distinguish building entrances.
(11) On a corner building, there shall be a corner entrance or at least one entrance on each street facing façade.
(12) A building shall provide multiple entrances on any street facing frontage that is wider than a typical lot for the block, with an entrance at least every 50 feet for buildings over 50 feet in length.
(13) Habitable space shall occupy at least 50% of the cumulative length of the streetwall of a building. Where a building occupies an entire block, the inhabitable streetwall must be distributed so that it is not all located on one half of the block.
(14) When a development includes or is adjacent to a historic structure, the design of the new building or addition should reinforce its character with a design that respects established cornice lines, horizontal and vertical facade organization, and massing of historic buildings in the context.
(15) Buildings date the historical development of the city. A new building or addition should avoid mimicking a past architectural style in such a way that it appears to have been built significantly earlier.
(16) A new building or addition shall utilize higher quality, durable materials, such as masonry, and appropriate architectural details at the ground floor / street level to accent the building and provide visual interest for pedestrians and motorists. Excluding single-family residences, EIFS (Exterior Insulation and Finish System) and vinyl siding are prohibited on the ground floor story of street and alley facing facades.
(17) A new building or addition shall be comprised of materials that are characteristic of the area. A majority of the District's structures are historic and utilize such materials as brick, wood siding, cast iron, and metal. Contemporary structures in the District highlight glass curtain wall and wall panel cladding systems.
(18) All storefront windows and doors at ground level shall have clear glass or light window tinting (allowing 70% or more of visible light to pass through). Highly tinted or mirrored glass is not permitted unless approved for "special conditions". Examples of "special conditions" include restaurant kitchen areas, storage space, and restrooms that need to be screened or hidden from public view.
(19) A new building or addition should have a visual terminus, such as a cornice at the top of a wall, to help articulate the architecture and to provide a finished look.
(20) A new building or addition should not have a blank or unarticulated walls visible from the street. Variations on the facade plane such as inset entries, building piers, and other details can assist in providing relief to long expanses of building wall.
(21) A new building or addition for residential use should provide balconies and terraces.
(22) If a building includes structured parking, it shall be integrated into the design of the building. A parking garage visible from the street shall be integrated into its surroundings and provide active and inviting street level appearance. Structured parking and parking garages should avoid having ramped floors visible from the street; provide articulated openings and entrances; minimize the size of vehicle entries; and screen parked cars from pedestrian view.
(23) All new mechanical equipment that is visible from other buildings or the street should be installed to have a minimal impact on adjacent properties and from public view unless the equipment is solar dependent. In this instance, function supersedes design. Rooftops should not look cluttered from any pedestrian vantage point. All mechanical or utility equipment should be well-integrated into the overall design.
(24) Accessory structures shall not be constructed or permitted within any required setback/yard. These structures shall be subordinate in size to the principal structure, shall not be visible from the public street, and shall be screened from adjacent residential areas by fencing or walls.
(25) Excluding situations in which the building official has determined that there is a risk to public safety, in addition to a wrecking permit, a building shall not be demolished until an Overlay Permit and a building permit have been issued for the replacement of the building with new development.
(26) Buildings that are found to be contributing to the District by the Committee shall not be demolished or substantially altered.
(C) Building design guidelines - awnings and attached canopies. Awnings and canopies can add aesthetic value as well as provide shade and cover for pedestrians. Awnings and canopies should be mounted in locations that respect the design of a building and the neighboring structures, including the arrangement of bays and openings. In general, they should not obscure transom windows, grillwork, piers, pilasters, or ornamental features of a structure.
(1) Shed awnings are visually lighter and have simpler features, and they are more traditional in appearance than convex or bull nose awnings. Awnings with no end panels are more transparent and allow better views into openings and storefronts. Convex (or bull nose) awnings are not permitted.
(2) Approved awning fabric materials include canvas and vinyl.
(3) A metal or glass canopy is permitted if it is compatible with the design and scale of the building.
(4) Awnings and canopies are to be installed at a minimum of 9'-0" above finished grade so that pedestrian entry clearances are operationally functional. Awnings must project a minimum of 24" from the building. They should be mounted on the wood or metal framing within a door or window opening (and not on the wall surrounding the opening).
(5) In openings with transoms, awnings should be mounted on the horizontal framing element separating the storefront window from the transom. Awnings should be designed to project over individual window and door openings and not be a continuous feature extending across an entire façade.
(6) Damage to a contributing structure shall be avoided when installing an awning. Hardware should be limited to that which is required for structural stability and should be driven into mortar joints, not masonry.
(D) Site design guidelines. Site planning is an important part of any project. Sites should incorporate attractive and maintainable landscaping to enhance the hardscape of the building. Landscaping should be used to minimize the visual impact of parking lots and service areas in the District.
(1) New commercial developments should provide adequate and significant screening to residential structures on contiguous properties. Opaque landscape buffers and other forms of screening should be used to minimize noise and lighting impact.
(2) Minimum 4'-0" wide landscape buffer area containing a 36" minimum height (at maturity) screen shall run along 90% of the lineal area in front of the patio, plaza, or outdoor space that faces the street. This landscape buffer area shall include permanent landscaping material such as trees (minimum 1 3/4" caliper size at time of planting), shrubs (minimum 18" height at time of planting), groundcover, and/or perennials. Fences, planters, and/or walls (maximum height of 36") are permitted within the landscape buffer area. Landscape buffer plantings shall be installed prior to occupancy or use of the patio, plaza, or outdoor space.
(3) Existing trees located within the property or adjacent property along the street, alley, or access easement shall be preserved and protected unless a qualified arborist determines they are not healthy or are dangerous and should be removed. Removed trees should be replaced with appropriate trees. The replacement trees shall be sized at a minimum of 1 3/4" caliper (at time of planting). Replacement tree(s) shall be planted within three months of the tree(s) removal or during the next planting season, whichever comes first.
(4) Service and loading areas shall be located to the rear, accessible by alleys when possible.
(5) New drive through facilities, windows, and lanes are prohibited.
(6) Design elements such as building configuration and streetscape design, including lighting, shall be used to support visual and pedestrian connections to open space. Provide water features where appropriate.
(7) Intensity, location, color, and direction of outdoor lighting shall be sensitive to nearby residential areas.
(8) Development shall minimize the adverse visual impact of utility lines on the area. Underground lines or service from the alley, where feasible, is encouraged.
(9) Fencing and screening shall be constructed of materials compatible with the principal structure.
(10) Chain link fencing is prohibited, except as a temporary measure.
(11) Barbed wire, razor wire, and other such materials are prohibited on fencing and walls.
(12) Permanent service counters, service bars, elevated decks, or similar structures may not be constructed in front of a building's primary street facing facade. If required and designed appropriately, low elevation decks are acceptable for outdoor dining.
(13) A new surface parking lot with no principal structure is prohibited and an existing surface parking lot with no principal structure shall not be expanded.
(14) New surface parking may only be permitted if adequately screened from pedestrian view, located on the same site as the principal use in which it serves, and contains no more than the minimum off-street parking requirement. Such a parking area adjacent to a public sidewalk must use landscaping, trees, colonnades or other construction to maintain the building line created by structures along the sidewalk. Side parking lots which exceed 40% of the total linear lot frontage adjacent to right-of-way shall provide a 36" high masonry, stone, or concrete wall that makes reference to a similar design within the surrounding area, extending from the principal structure across the front of the parking area. The 36" tall wall can wrap around any existing or proposed monument signage to maintain visibility.
(15) Shared parking areas that are more efficient and accessible are encouraged.
(16) The number and width of curb-cuts should be minimized to promote pedestrian circulation and safety. Existing continuous curb-cuts should be reduced to the minimum widths necessary for vehicular ingress/egress or removed when not required. Development should place curb cuts at alley locations where possible.
(17) Specialty pedestrian paving, such as pavers, should continue at a level walking surface across mid-block curb cuts.
(18) Adequate perimeter landscaping, fencing, or a combination of both is required to help screen vehicles and/or equipment from public view. The screening height for vehicle parking lots shall be 36" above finished grade of the lot. This height will enable drivers of vehicles to safely see and avoid other pedestrians and vehicles while screening most parked cars. A 7'-0" max high screened fence or wall can be used for industrial or commercial sites to screen for large vehicles or equipment on site.
(19) Provide sidewalk connections to plazas and open spaces.
(20) Street furniture should be provided in or adjacent to the public right-of-way for pedestrian use.
(21) Allow sufficient room for tree canopies to grow and develop without conflict with other building elements.
(22) In high pedestrian use areas, tree guards should be installed to protect the trunks from damage. A guard should provide sufficient space for the mature trunk size of the specific species or should be adjustable as the tree matures.
(E) Sign design guidelines. Signage is important to many businesses and organizations. By posting signs, businesses not only create a brand image for themselves, but also create an opportunity to attract customers. The signage guidelines promote attractive, artistic, well-proportioned and thoughtfully located signs, which will allow for wayfinding and enhance the District.
(1) Significant, historic, and contributing signs shall be preserved, maintained, and, if possible, re-used. "Significant, historic, or contributing signs" are signs that are unique in design or material fabrication. These signs contribute to the history and diverse character of the District. (See list of significant, historic, or contributing signs below).
List of significant, historic, and contributing signs.

(2) Significant, historic, or contributing signs or graphics that have been painted directly onto walls and represent out of date logos or logos for businesses that are no longer in business are encouraged to remain in either their existing faded condition or restored to their original condition where appropriate. These signs are recognized as contributing to the historic artistic character of the area and our community.
(3) Freestanding pole signs are prohibited. Existing pole signs that are associated with a property that has not been abandoned or vacant for a period of less than one year may be restored or refaced, but not expanded in size.
(4) Back-lit cabinet signs and monument signs, including re-faced signs, shall have opaque, non-Illuminated face panels; only the individual letters and/or logos should be back-lit, not the entire surface of the sign.
(5) Attached wall signs or projecting signs are preferred. Attached signage composed of individual letters or symbols is strongly preferred.
(6) Signs that incorporate flashing text, animation, moving graphics, video, or changing image signage with a text change rate greater than one hour are prohibited.
(7) Storefront window signage including temporary window signage, window cling signs, and promotional advertising shall not exceed 25% of the total window area. Neon and hanging window signs are encouraged, and add to the "active atmosphere" for both vehicles and pedestrians.
(8) Projecting wall signs can be erected or attached to a building's wall and extend a minimum of 18" to a maximum of 8'-0" from the wall surface. These signs are mounted perpendicular to the building's facade.
(9) Projecting banner signs can project no more than 24" from the face of the building. These signs should be attached so that they do not "flap" in the air, and should be removed or replaced when they show signs of wear or fading.
(10) Multiple signs placed on a building's facade should be compatible in size, material, and design with other signage located on the structure.
(11) Permanent banner signage shall be made of canvas material or matte textured vinyl material. Permanent banner signage should be removed or replaced when they show signs of wear or fading.
(12) Lettering, logos, and other symbols shall take up less than 33% of the total area of an awning that is attached to a commercial structure. It is recommended that signs and logos be located on the valance area of awnings that have them.
(13) All wood signs need to be stained or painted and have a finished appearance.
(14) Existing non-conforming signage must be removed prior to new approved signs being installed. A "significant, historic, or contributing sign" as identified in these guidelines is exempt from this requirement.
(15) Neon and neon simulated bulbs (such as "fiber optic" and "LED lighting strips" that simulate neon) are encouraged and help to maintain a sense of activity and contribute to the animated environment of the District.
(16) Projecting light fixtures used for externally illuminated signs shall be simple and unobtrusive in appearance. They should not obscure the graphics of the sign.
(17) Directional signage is used to direct pedestrian or vehicular traffic. No more than one image, logo, or text combined with the "entry" or "exit" text is allowed on each directional sign. Directional signage cannot exceed 3'-0" in height above finished grade.
(18) All exposed conduit, electrical transformer boxes, and electrical raceways should be concealed from public view, or painted to blend in with background.
(19) New outdoor advertising billboards are prohibited. Removal of existing billboards is highly encouraged.
(20) Signs shall be mounted or erected so they do not obscure the architectural features or openings of a building.
(21) Signs may not be located in the right-of-way unless they are approved by the public works department. Exceptions include portable "A" frame signs. "A" frame signs cannot exceed 4'-0" in height and 3'-0" in width, shall not be placed in locations that impede pedestrian traffic, and shall be located in front of the storefront near the entrance.
(22) No sign or portion of a sign shall extend above the cornice line at the top of the building facade. Rooftop signs are prohibited.
(F) Historic preservation design guidelines. Historic buildings (50 years of age or older) comprise a significant part of the District and are physical reminders of Louisville's early history. The historic buildings in the area are some of the oldest remaining in the city and exhibit characteristics of classic urbanism. Historic structures define the area's origins while providing unique adaptive reuse potential. Structures over 100 years old are sometimes flanked by more contemporary mid-century ones that exhibit similar urban characteristics of scale, massing, and setback, and are thus contributing structures in their own right. Given the important role of many existing buildings to the history and streetscape of the area, demolition of any contributing structure will entail stringent review.
(1) Changes to the exterior of Contributing Historic Structures and other structures within the Overlay District that were constructed 50 years ago or longer and have not been significantly altered, shall be reviewed in accordance with the standards established for contributing historic structures by the United States Secretary of the Interior. However, the Committee may relax these standards in the interest of accomplishing the intentions and objective of these guidelines.
(2) The design of new or substantially remodeled structures that are adjacent to contributing historic structures should be compatible with them and should incorporate similar horizontal and vertical planes or references where appropriate.
(3) Alterations to a historic building that has not been identified as contributing as part of a National Register District should be carried out in accordance with the standards established for contributing historic structures by the United States Secretary of the Interior.
(4) Existing structures that are identified locally or nationally as having significant historic character should be retained and incorporated into new development.
(5) No application to demolish any contributing historical structure or structure built 50 years ago or longer shall be approved by the Urban Design Administrator or Committee unless the applicant demonstrates to the satisfaction of Urban Design Administrator/Committee and the Historic Preservation Officer:
(a) That the rehabilitation of a structure or construction of a new structure will have a greater positive impact on the area's economic vitality and appearance than would preservation of the structure proposed to be demolished; and the rehabilitation of the structure or the construction of the new structure would not be possible or economically feasible without the demolition of the structure proposed to be demolished; or
(b) That the applicant cannot obtain a reasonable economic return from the property or structure unless the contributing historical structure or structure constructed 50 years ago or longer is demolished in accordance with the application.
(6) A historic structure shall not be demolished until a building permit is secured for the approved development that necessitates the demolition. The historic structure should be adequately maintained and not neglected during this period. The Urban Design Administrator or Committee may apply a condition of approval stating the overlay permit involving demolition of a historic structure is null and void if no progress is made on the approved development that necessitated the demolition within a specified timeframe.
(G) Public art design guidelines. Public art is the continuously growing record of the community's identity, creativity, values, and its highest aspirations. Public art is artwork that is accessible to the public and created through a public process that considers the social and physical context of the site. Public art contributes to the local economy and adds to the richness of the community. Public art should be included in every project's development plan.
(1) Public art should be available for the enjoyment and enrichment of people within the community. The plan should include a meaningful allowance for public art in the planning and construction of all projects.
(2) Public art can include all mediums, such as sculpture, mural or painting, film, light, or other forms of creative expression that are viewable on a site or building. Commercial logos or elements of commercial advertising for a business or organization are not considered public art.
(3) Public art shall be designed, executed, and supervised by recognized artists or other design professionals who have been trained or have consistently provided examples of artistic work in their medium of expression.
(4) Public art, if implemented, should be integrated with the design of the project or development, and shall aesthetically enhance the urban environment of the District.
(5) Where applicable, public art proposals should conform to the design guidelines and master plan established by the Committee for Public Art (COPA).
(6) Public art shall be appropriate to its setting, surrounding architecture, and social context.
(7) Public art may include installations that are focused on expressing local history, celebrating and identifying the neighborhood, and expressing civic pride.
(8) In order to not be further classified and regulated as a sign, public art cannot contain an advertisement in any form, actual or perceived, including but not limited to a slogan, logo, graphic, distinctive emblem, trademark, web address, or phone number that identifies a commercial business or a product or service offered by businesses, business complexes, schools, attractions, historical or tourist locations, malls, or other organizations (charitable, non-profit, fraternal, religious, political organizations, etc.). However, the art may include a logo, emblem, or trademark to acknowledge the sponsor or artist so long as the inclusion is incidental to the artwork and does not alter the message of the art, and its primary purpose is not to serve as an advertisement for the sponsor or artist's products or services.
(9) Murals shall be produced to remain in good condition for a duration of at least ten years. Murals should be maintained and repaired by the property owner if the surface is damaged, faded, or vandalized. Protective coatings are encouraged. Treatment operations include, but are not limited to, cleaning, retouched damaged or faded surfaces, reattachment of plaster detached from the wall, re-adhering flaking paint, and graffiti removal.
(10) Public art shall be incorporated into plazas and open spaces that are open to public access or view. Consider any built element as an opportunity for art, such as walls, paving, manhole covers, railings, signage, etc.
(H) Sustainability design guidelines. Incorporating environmentally sustainable elements into the design and construction of the built environment in the District is an important part of any project. Environmentally sustainable elements include: transit facilities, green buildings, heat island reduction, recycled content in infrastructure, and stormwater management.
(1) New Infrastructure is encouraged to use at least 50% by mass, recycled or reclaimed materials.
(2) Projects should retain, reuse, and/or infiltrate on-site, all of the stormwater that falls on their parcel(s).
(3) The surface area of a landscaped or pervious condition slated for a repurposed use must maintain a level of permeability greater than or equal to its current state.
(4) Minimize the amount of hard pavement and ground cover which retains heat. Provide only the amount necessary.
(5) Maximize the amount of vegetation in trees, shrubs, groundcovers, and vines which cool the surrounding areas.
(6) Transit facilities should have a covered shelter, seating, bike racks, information kiosks, and appropriate signage.
(7) New commercial, industrial, and residential buildings should achieve standard sustainability certifications, such as LEED.
(8) New or replacement roofs with energy efficient "radioactive properties" should be considered.
(9) Living roofs are encouraged. A living roof, also known as a green roof or vegetated roof, is a roof that is partially or completely covered with vegetation and a growing medium, such as soil, that is planted over a waterproofing membrane.
