Chapter 1 Introduction

Introduction North Platte has a long and historic past. The community has been a key economic center since its beginnings considering the development around the Union Pacific Railroad. However, it becomes difficult to understand and appreciate the historic past if the artifacts and structures that tell the story are no longer in existence.

The purpose of this document is to provide standards and guidelines in areas of the community containing groupings as well as individual structures that help tell the history of North Platte’s past. As of this document, the city had lost a considerable number of notable structures within the community and the remaining structures are precious to telling the future about the past.

Historic preservation is a very common need for communities world-wide; however, those of us in the United States, more so in the Midwest/Great Plains region, have, until the past 20 years or so, have found it easier to demolish old structures and replace them with more “modern” structures or make the land into a parking lot. North Platte has been guilty of this in the past and is now moving to preserve those historic structures for the future.

Introduction

The Lost is Gone Forever This section within the Introduction gains a lot of insight from the publication “City Bones: Landmarks of North Platte, Nebraska, 2d Edition. The specific part of the book needing focus is a section of the lost structures/”landmarks” of the downtown area. The intent of this section is to inform the person, group, company/corporation engaged in redeveloping area of downtown North Platte what has been lost and why it is critical to preserve what is remaining.

Area and structures lost to Urban Renewal

The current downtown area in North Platte once contained another three city blocks; plus, the Union Pacific Railroad Depot. The three blocks were lost in the late 1960’s, during the Urban Renewal movement. Within the three blocks there were nearly 50 buildings torn down during this period.

Photo 1.1 Aerial of old North Platte Downtown In place of the demolished structures, the site was developed into a “modern” strip center with over 2-blocks of surface parking. The new construction also disconnects the downtown from one of the downtown’s greatest assets, the railroad. Historically, downtowns had a direct connection to the railroad and its Depot, North Platte has completely lost this connection of the past.

Introduction

Urban Renewal and the Remaining Downtown Besides the three blocks cleared for the new strip center and surface parking, other downtown improvements attempted to recreate the “mall concept” in the remaining portion of downtown, especially along two blocks of Dewey and in the intermediate alleyways.

The Dewey Street canopies provided a shopper with a covered experience once they made it from their car to the sidewalk. This was likely intended to provide storefront parking with a sense of the “mall experience”. Downtowns, across the United States, during this period were constructing similar canopies, as well as, closing the streets to vehicular traffic in order to provide the “mall experience” in downtown. Unfortunately, many downtowns found out Photo 1.3 View down the permanent canopy built as part of the Urban Renewal project the canopies only hid the stores further from the street and sometimes made it difficult for shoppers to locate a particular business.

During the 45 or so years since the Urban Renewal program came to North Platte, a number of structures were modified in ways not consistent with the time period the structure was constructed. The canopy removal has triggered enthusiasm in downtown to be “true” to the structures past and the era in which the downtown represents.

Turning Back the Clock This study and set of Preservation Guidelines are due in part to the city of North Platte deciding to turn back the clock.

Beginning in 2017, the City made plans for demolishing the permanent canopies and re-exposing the older historic facades completely from the street.

Introduction Exposing the structures once again has created an issue of “how do building owners start to repair and renovate the areas covered up for the past 45 years or so?” The removal of the permanent canopies presented a significant number of options to building/business owners.

Looking Forward Looking forward to what will be in Downtown North Platte requires the community to examine the past and respect: • the design, • The materials, • The construction techniques, and • The vocabulary of the building.

Photo 1.5 View of a recently exposed leaded glass transom on Dewey Street

Many of these will be reviewed and discussed in the Design Guideline Chapter.

Not Just About Downtown Historic Preservation and these Design Guidelines are not just for Downtown North Platte. These can and should be applied wherever possible in North Platte. North Platte is well known for their older homes including bungalows, Victorian homes, and many more styles. Many of of these have been cared for and maintained over the years; however, as they become older it will become critical to follow specifics similar to those listed above in “Looking Forward” . The next page has some excellent examples of the older housing stock in North Platte,

Approaches to Preservation

•

There is an approach to Preservation undertaken by the City of North Platte Historic Preservation Zoning Overlay District.

•

Historic Preservation Zoning Overlay District This area is predominately over the historic downtown area and extending across US Highway 83/Jeffers Street and south to the historic entrance to downtown. Within this area the Design Guidelines will be strictly enforced under certain circumstances. These circumstances are: • effective on any structure on or considered eligible for designation on the National Register (see Chapter 2: Existing Structure Eligibility), • Any structure receiving state and/or Federal Historic Tax Credits, • Any structure receiving money from the Nebraska VIP program, • whenever there are local funds granted to a building owner, and/or • there are any state and/or Federal funds being used which requires a Section 106 Review, these Guidelines apply.

Certified Local Government North Platte is considered a Certified Local Government (CLG) by NHS. According to NHS the CLG designation is a: Partnerships to promote local preservation between: • local government (city or county) • Nebraska State Historic Preservation Office • National Park Service Qualifications as a CLG requires: • establish a historic preservation ordinance that includes protection for historic properties

North Platte, NE Historic Preservation Design Guidelines

•

create a preservation commission to oversee the preservation ordinance and the program provide for public education and participation, including nomination of properties to the National Register of Historic Places conduct and maintain a survey and inventory of historic properties.

Financial Incentives ...city or county is eligible for grants to assist local preservation programs. You can use the grant for: • surveys • National Register nomination preparation • publications • staff support • workshops • Events Contributing buildings within local landmark districts may be eligible for preservation tax incentives without listing on the National Register of Historic Places.

Being a CLG provides North Platte: • another tool when considering planning, zoning, and land use issues using your local landmark process and survey programs • ability to preserve structures that reflect the community's heritage • a way to promote pride in the community's history • technical help and training from our office.

• access to a network of local, state, federal, and private preservation groups. **Italicized verbiage is taken directly from the NHS website

Chapter 2 Historic Downtown Structure Survey

The Nebraska Historical Society (NHS) occasionally surveys different areas of communities and counties in Nebraska to determine if there are structures, landscapes, and/or sites worthy of being at a minimum a contributing entity to an overall historical area. NHS performed one of these surveys during the summer and fall of 2009 in downtown North Platte.

Figure 2.1 NHS Study Area

Base Map Source: Google Earth Study Area Source; NHS

North Platte, NE Historic Preservation Design Guidelines

11

Historic Downtown Structure Survey The survey area covered over 81 blocks, both north and south of the Union Pacific Railroad tracks, as indicated in Figure 2.1. The survey documented 65 properties within the study area boundaries. According to the study, “Every public street was traversed to insure a complete inventory of the properties.”

Review Criteria (NHS) According to the survey from NHS, the following criteria were: Criterion A. The property is associated with events that have made a significant contribution to the broad patterns of our history.

Criterion B. The property is associated with the lives of persons significant in our past.

Criterion C. The property embodies the distinctive characteristics of a type, period, or method of construction, or represents the work of a master, or possesses high artistic values, or represents a significant and distinguishable entity whose components may lack individual distinction.

Criterion D. The property has yielded, or is likely to yield, information important in prehistory or history (primarily applied to archaeological sites).

Certain property types are not usually considered for listing in the National Register: religious properties, moved properties, birthplaces and graves, cemeteries, reconstructed properties, commemorative properties, and properties achieving significance within the past fifty years. However, these properties may be eligible if any of the following criteria considerations apply:

12

Religious properties deriving significance from architectural or artistic distinction or historical importance.

Moved properties significant for their architectural value or that are the surviving structure most importantly associated with a historic person or event.

Birthplaces or grave sites of historical figures of outstanding importance if there are no other appropriate sites or buildings directly associated with that person.

Cemeteries that derive their significance from graves of people of outstanding importance, from age, from distinctive design features, or from association with historic events.

Reconstructed buildings that are accurately executed in an appropriate environment when no other building or structure with the same association has survived.

Commemorative properties whose design, age, tradition, or symbolic value has imbued it with its own significance.

Properties that have achieved significance within the past fifty years if they are of exceptional importance.

• Integrity, as defined by the National Park Service, is the authenticity of a property's historic identity, evidenced by the survival of physical characteristics that existed during the property's historic period. Seven qualities help to evaluate the integrity of a property: • Location: the place where the historic property was built or where the historic event occurred.

North Platte, NE Historic Preservation Design Guidelines

Historic Downtown Structure Survey • • • •

• •

Design: the shape, size, plan, structure, and style of the property.

Setting: the physical environment surrounding the historic property.

Materials: the building materials that were used to construct the property.

Workmanship: the evidence of the crafts, techniques and skills of a particular culture or people used to create the property.

Feeling: the property's expression of its historic sense of a particular period of time.

Association: the direct link between an important historic event or person and the historic property.

Specifically Identified Structures The following structures were determined to either be on the National Register of Historic Places or were considered a contributing structure. As the City and building owners continue to rebuild after the removal of the permanent canopies, more buildings are likely to be recognized by NHS. A final note, since North Platte is a Certified Local Government, the City has the ability to designate their own structures prior to or without any State designation and still qualify for the tax credit program,.

Structures Currently on the National Register in North Platte • The Lincoln County Courthouse  The courthouse is located at 301 North Jeffers Street • The Hotel Pawnee (Old Yancey Hotel)  The Hotel Pawnee is located at 221 East 5th Street • The Fox Theater  The Theater is located at 301 East 5th Street

Between the local Historic Preservation Commission and local building owners, there is reinvigoration to preserve these wonderful buildings for the future. The following are some key steps needing to be implemented: • At a minimum, the local Historic Preservation Commission and City should continue what they recently started via rehabilitation grant; • The local HPC/CLG should designated these buildings as critical to the local history and require preservation; • The NHS should re-evaluate these buildings and declare them as contributing; and/or • Designate a portion of the overlay district as a Historic District.

Preservation Ordinances

Chapter 3 Preservation Ordinances

With the critical structures/buildings identified, the primary way to protect these buildings/structures is through either a Preservation Ordinance.

Historic Preservation Ordinance A Historic Preservation Ordinance is an implementation tool which allows the local government to protect and guide the future restoration and redevelopment of key buildings or an entire defined area. The tools at the North Platte Historic Preservation Commission reach include: • An Historic Preservation Zoning Overlay District; • Specific Design Guidelines for rehabilitation; and • Funding resources The actual Ordinance will only be enforceable when: • There are local funds contributing to a project; • There are state Historic Tax Credits involved; • There are Federal Historic Tax Credits involved; and/or • The project via some triggering mechanism is required to perform a Section 106 review.

Local funds may include grants and/or Tax Increment Financing. It is strongly recommended, when Tax Increment Financing is being used in the Historic Preservation District, that one of the requirements for the funding is following the Design Guidelines.

Chapter 4 Secretary of the Interior’s Standards for Rehabilitation

The Secretary of the Interior’s Standards for Rehabilitation examines all aspects of rehabilitating a structure, including several exterior and interior parts of a building. These items are: • Building Exterior - Masonry • Building Exterior - Wood • Building Exterior - Architectural Metals • Building Exterior - roofs • Building Exterior - Windows • Building Exterior - Entrances and porches • Building Exterior - Storefronts • Building Interior - Structural Systems • Building Interior - Spaces, Features, and Finishes • Building Interior - Mechanical Systems • Building Site The standards also examine the “setting” of a neighborhood or District, Energy Conservation, New Additions, Accessibility, and Health and Safety. All of these, within the paragraph, “should” be considered regardless.

North Platte Funding North Platte’s local funding for projects within the identified districts is strictly concerned with rehabilitation standards relating to the exterior, additions to historic structures, accessibility and Health and Safety. For purposes of this study, the Design Guidelines described and illustrated in this Chapter.

Other Funding Sources North Platte’s funding is concerned only with those items discussed in the previous paragraph; however, ANY PROJECT wishing to use other funding sources or are required to meet specific standards due to “Section 106” review shall be required to meet all prescribed areas of the Secretary of the Interior’s Standards for Rehabilitation. These standards are not found within this document but are available through the Nebraska State Historical Society.

The following pages of text are taken directly from the Secretary’s Standards; however, where possible local photos will be used as examples.

Building Exterior - Masonry The longevity and appearance of a masonry wall is dependent upon the size of the individual units and the mortar.

Stone is one of the more lasting of masonry building materials and has been used throughout the history of American building construction. The kinds of stone most commonly encountered on historic buildings in the U.S. include various types of sandstone, limestone, marble, granite, slate and fieldstone. Brick varied considerably in size and quality. Before 1870, brick clays were pressed into molds and were often unevenly fired. The quality of brick depended on the type of clay available and the brickmaking techniques; by the 1870s--with the perfection of an extrusion process--bricks became more uniform and durable. Terra cotta is also a kiln-dried clay product popular from the late 19th century until the 1930s. The development of the steel-frame office buildings in the early 20th century contributed to the widespread use of architectural terra cotta. Adobe, which consists of sun-dried earthen bricks, was one of the earliest permanent building materials used in the U.S., primarily in the Southwest where it is still popular.

Mortar is used to bond together masonry units. Historic mortar was generally quite soft, consisting primarily of lime and sand with other additives. After 1880, portland cement was usually added resulting in a more rigid and non-absorbing mortar. Like historic mortar, early stucco coatings were also heavily lime-based, increasing in hardness with the addition of portland cement in the late 19th century. Concrete has a long history, being variously made of tabby, volcanic ash and, later, of natural hydraulic cements, before the introduction of portland cement in the 1870s. Since then, concrete has also been used in its precast form.

While masonry is among the most durable of historic building materials, it is also very susceptible to damage by improper maintenance or repair techniques and harsh or abrasive cleaning methods.

Aluminum storefront

Metals commonly used in historic buildings include lead, tin, zinc, copper, bronze, brass, iron, steel, and to a lesser extent, nickel alloys, stainless steel and aluminum.

Historic metal building components were often created by highly skilled, local artisans, and by the late 19th century, many of these components were prefabricated and readily available from catalogs in standardized sizes and designs.

Building Exterior - Roofs The roof--with its shape; features such as cresting, dormers, cupolas, and chimneys; and the size, color, and patterning of the roofing material--is an important design element of many historic buildings.

Cupolas

In addition a weathertight roof is essential to the long-term preservation of the entire structure. Historic roofing reflects availability of materials, levels of construction technology, weather, and cost.

For example, throughout the country in all periods of history, wood shingles have been used--their size, shape, and detailing differing according to regional craft practices. European settlers used clay tile for roofing as early as the mid-17th century. In some cities, such as New York and Boston, clay was popularly used as a precaution against fire.

The Spanish influence in the use of clay tile is found in the southern, southwestern and western states. In the mid-19th century, tile roofs were often replaced by sheet metal, which is lighter and easier to maintain.

Evidence of the use of slate for roofing dates from the mid-17th century.

Slate has remained popular for its durability, fireproof qualities, and its decorative applications. The use of metals for roofing and roof features dates from the 18th century, and includes the use of sheet iron, corrugated iron, galvanized metal, tin-plate, copper, lead and zinc.

Awareness of these and other traditions of roofing materials and their detailing will contribute to more sensitive treatment.

Building Exterior - Windows Technology and prevailing architectural styles have shaped the history of windows in the United States starting in the 17th century with wooden casement windows with tiny glass panes seated in lead cames. From the transitional single-hung sash in the early 1700s to the true double-hung sash later in the same century, these early wooden windows were characterized by the small panes, wide muntins, and the way in which decorative trim was used on both the exterior and interior of the window.

As the sash thickness increased by the turn of the century, muntins took on a thinner appearance as they narrowed in width but increased in thickness according to the size of the window and design practices. Regional traditions continued to have an impact on the prevailing window design such as with the long-term use of "french windows" in areas of the deep South.

Changes in technology led to the possibility of larger glass panes so that by the mid-19th century, two-over-two lights were common; the manufacturing of plate glass in the United States allowed for dramatic use of large sheets of glass in commercial and office buildings by the late 19th century. With mass-produced windows, mail order distribution, and changing architectural styles, it was possible to obtain a wide range of window designs and light patterns in sash.

Popular versions of Arts and Crafts houses constructed in the early 20th century frequently utilized smaller lights in the upper sash set in groups or pairs and saw the re-emergence of casement windows. In the early 20th century, the desire for fireproof building construction in dense urban areas contributed to the growth of a thriving steel window industry along with a market for hollow metal and metal clad wooden windows As one of the few parts of a building serving as both an interior and exterior feature, windows are nearly always an important part of the historic character of a building. In most buildings, windows also comprise a considerable amount of the historic fabric of the wall plane and thus are deserving of special consideration in a rehabilitation project.

Building Exterior - Windows Identify, retain, and preserve Recommended • Identifying, retaining, and preserving windows--and their functional and decorative features--that are important in defining the overall historic character of the building.

• Such features can include frames, sash, muntins, glazing, sills, heads, hoodmolds, paneled or decorated jambs and moldings, and interior and exterior shutters and blinds.

• Conducting an in-depth survey of the conditions of existing windows early in rehabilitation planning so that repair and upgrading methods and possible replacement options can be fully explored.

Not Recommended • Removing or radically changing windows which are important in defining the historic character of the building so that, as a result, the character is diminished.

• Changing the number, location, size or glazing pattern of windows, through cutting new openings, blocking-in windows, and installing replacement sash that do not fit the historic window opening.

• Changing the historic appearance of windows through the use of inappropriate designs, materials, finishes, or colors which noticeably change the sash, depth of reveal, and muntin configuration; the reflectivity and color of the glazing; or the appearance of the frame.

• Obscuring historic window trim with metal or other material.

• •

Stripping windows of historic material such as wood, cast iron, and bronze.

Replacing windows solely because of peeling paint, broken glass, stuck sash, and high air infiltration. These conditions, in themselves, are no indication that windows are beyond repair.

Protect and Maintain Recommended • Protecting and maintaining the wood and architectural metal which comprise the window frame, sash, muntins, and surrounds through appropriate surface treatments such as cleaning, rust removal, limited paint removal, and re-application of protective coating systems.

• Making windows weathertight by re-caulking and replacing or installing weather stripping. These actions also improve thermal efficiency.

• Evaluating the overall condition of materials to determine whether more than protection and maintenance are required, i.e. if repairs to windows and window features will be required.

Building Exterior - Entrances and Porches Entrances and porches are quite often the focus of historic buildings, particularly on primary elevations. Together with their functional and decorative features such as doors, steps, balustrades, pilasters, and entablatures, they can be extremely important in defining the overall character of a building.

In many cases, porches were energy-saving devices, shading southern and western elevations. Usually entrances and porches were integral components of a historic building's design; for example, porches on Greek Revival houses, with Doric or Ionic columns and pediments, echoed the architectural elements and features of the larger building.

Central one-bay porches or arcaded porches are evident in Italianate style buildings of the 1860s. Doors of Renaissance Revival style buildings frequently supported entablatures or pediments.

Porches were particularly prominent features of Eastlake and Stick Style houses; porch posts, railings, and balusters were characterized by a massive and robust quality, with members turned on a lathe. Porches of bungalows of the early 20th century were characterized by tapered porch posts, exposed post and beams, and low pitched roofs with wide overhangs.

Art Deco commercial buildings were entered through stylized glass and stainless steel doors.

Building Exterior - Storefronts The storefront is usually the most prominent feature of a historic commercial building, playing a crucial role in a store's advertising and merchandising strategy. Although a storefront normally does not extend beyond the first story, the rest of the building is often related to it visually through a unity of form and detail. Planning should always consider the entire building; window patterns on the upper floors, cornice elements, and other decorative features should be carefully retained, in addition to the storefront itself.

The earliest extant storefronts in the U.S., dating from the late 18th and early 19th centuries, had bay or oriel windows and provided limited display space. The 19th century witnessed the progressive enlargement of display windows as plate glass became available in increasingly larger units. The use of cast iron columns and lintels at ground floor level permitted structural members to be reduced in size. Recessed entrances provided shelter for sidewalk patrons and further enlarged display areas.

In the 1920s and 1930s, aluminum, colored structural glass, stainless steel, glass block, neon, and other new materials were introduced to create Art Deco storefronts.

New Additions An attached exterior addition to a historic building expands its "outer limits" to create a new profile.

Because such expansion has the capability to radically change the historic appearance, an exterior addition should be considered only after it has been determined that the new use cannot be successfully met by altering non-character-defining interior spaces.

If the new use cannot be met in this way, then an attached exterior addition is usually an acceptable alternative. New additions should be designed and constructed so that the character-defining features of the historic building are not radically changed, obscured, damaged, or destroyed in the process of rehabilitation. New design should always be clearly differentiated so that the addition does not appear to be part of the historic resource.

Note: Although the work in this section is quite often an important aspect of rehabilitation projects, it is usually not part of the overall process of preserving character-defining features (identify, protect, repair, replace); rather, such work is assessed for its potential negative impact on the building's historic character. For this reason, particular care must be taken not to obscure, radically change, damage, or destroy character-defining features in the process of constructing a new addition.

Accessibility It is often necessary to make modifications to a historic building so that it will be in compliance with current accessibility code requirements.

Accessibility to certain historic structures is required by three specific federal laws: the Architectural Barriers Act of 1968, Section 504 of the Rehabilitation Act of 1973, and the Americans with Disabilities Act of 1990. Federal rules, regulations, and standards have been developed which provide guidance on how to accomplish access in historic areas for people with disabilities. Work must be carefully planned and undertaken so it does not result in the loss of character-defining spaces, features, and finishes. The goal is to provide the highest level of access with the lowest level of impact.

Note: Although the work in this section is quite often an important aspect of rehabilitation projects, it is usually not part of the overall process of preserving character-defining features (identify, protect, repair, replace); rather, such work is assessed for its potential negative impact on the building's historic character. For this reason, particular care must be taken not to obscure, radically change, damage, or destroy character-defining features in the process of rehabilitation work to meet accessibility requirements.

Health and Safety In undertaking rehabilitation work on historic buildings, it is necessary to consider the impact that meeting current health and safety codes (public health, occupational health, life safety, fire safety, electrical, structural and building codes) will have on characterdefining spaces, features, and finishes.

Special coordination with the responsible code officials at the state, county or municipal level may be required. Securing required building permits and occupancy licenses is best accomplished early in work project planning. It is often necessary to look beyond the "letter" of code requirements to their underlying purpose; most modern codes allow for alternative approaches and reasonable variance to achieve compliance.

Some historic building materials (insulation, lead paint, etc.) contain toxic substances that are potentially hazardous to building occupants. Following careful investigation and analysis, some form of abatement may be required. All workers involved in the encapsulation, repair, or removal of known toxic materials should be adequately trained and should wear proper personal protective gear. Finally, preventive and routine maintenance programs for historic structures known to contain such materials should also be developed to include proper warnings and precautions.

Note: Although the work in this section is quite often an important aspect of rehabilitation projects, it is usually not part of the overall process of preserving character-defining features (identify, protect, repair, replace); rather, such work is assessed for its potential negative impact on the building's historic character. For this reason, particular care must be taken not to obscure, radically change, damage, or destroy character-defining features in the process of rehabilitation work to meet health and safety code requirements.

Signage This section has been put together by Marvin Planning Consultants and Berggren Architects. The following information and guidelines is purely based upon the historic use of signs and their placement on building facades.

Historic construction of buildings tended to follow a specific means to attracting consumers in an organized and usually stylish manner. The use of signs typically included many different types of signs. This section will define these sign types as well prescribe the best ways to use them on historic buildings.

When restoring or renovating a historic building, special care should be paid to how the occupant identifies themselves. Unfortunately, during the 1940's and into the early 1970's, there was little sensitivity to the method of signing businesses. During this period, many storefronts covered up the transom area with aluminum panels and large glowing signs.

These glowing signs were attached to either the aluminum panels or higher up to attract more customers.

Besides being sensitive to the location of signage, there needs to be some sensitivity to the style of sign. This should be in a typeface that reflects the architectural period. However, there should not be only one typeface to choose from but a number of typefaces to review. Three specific typefaces used in the past are:

• • •

Times New Roman Universe Avant Garde

These typefaces are simply an example of what has been used in the past. Businesses should be encouraged to investigate additional styles if these do not fit their needs.

Typically, the signage used within the Historic Main Street District should be returned to the transom area of the building. However, sometimes this would require the removal of materials attached in the past. By returning the signage to the transom level, the buildings will better reflect the period in which they were constructed.

Another signage location to be considered is under canopies and awnings. There are specific methods to handling these conditions. This type of signage allows pedestrians to see which establishment they are passing. A final approach to sign location is on the front of the canopy and/or awning. Placement along the front allows motorists an additional point to see the businesses in the Main Street area.

• Altering, damaging, or destroying character-defining spaces, features, and finishes while making modifications to a building or site to comply with safety codes.

• Destroying historic interior features and finishes without careful testing and without considering less invasive abatement methods.

• Removing unhealthful building materials without regard to personal and environmental safety.

• Making changes to historic buildings without first exploring equivalent health and safety systems, methods, or devices that may be less damaging to historic spaces, features, and finishes.

• Damaging or obscuring historic stairways and elevators or altering adjacent spaces in the process of doing work to meet code requirements.

• Covering character-defining wood features with fire-resistant sheathing which results in altering their visual appearance.

• Using fire-retardant coatings if they damage or obscure character-defining features.

• Radically changing, damaging, or destroying character-defining spaces, features, or finishes when adding a new code-required stairway or elevator.

North Platte, NE Historic Preservation Design Guidelines

New Construction on Existing Building Sites There are circumstances where a building as a whole may not be feasible for restoration.

The City of North Platte understands this may occur from time to time. However, there is a desire for the continuation of the existing façade profile of the downtown area. Therefore, the Preservation Commission is adopting “the Boulder, Colorado” standard within the existing downtown core and along US Highway 183 in the north Downtown area.

The Boulder Standard allows a property owner may replace their building in these areas but; • They must maintain any existing façade;

•

• • •

They may build taller than the existing building but the additional stories must begin 15 feet back from the façade; Any corner building should maintain both facades; If they match the number of stories then there will be no extensions allowed above the elevation of the front façade; and The front façade should be restored as part of any overall project.

Again, the premise behind this requirement is to maintain the existing façade profile along the main streets of downtown North Plate.

The photograph on the top right is from Boulder and it has preserved the original façade and the arrow is pointing to the addition. From the ground along the sidewalk, the scale of the building is still consistent with the past.

The area in between the original façade and new addition is typically used for terraces and outdoor eating areas depending upon the use.

The photo on the bottom right shows original facades but the infill and area behind is a parking garage.
