Historic Resources Map Version Date:October9,2019 Introduction Seward has a vibrant history that spans several generations and is reflected in the many historic structures that survived throughout the community. . Here, in the heart of the community, a diverse range of older buildings provide visual interest to residents and visitors, and stand as symbols of the community's role in the development of Alaska. The importance of this area is recognized by the Secretary of the Interior, with a listing in the National Register of Historic Places. In addition, the City of Seward has bestowed a local historic district designation on this part of downtown. This area is important to the community, the state and the nation. It is enjoyed by residents and visitors throughout the year. Preserving the integrity of the Downtown Historic District is a high priority for the community, because it saves a key part of Seward's heritage, enhances quality of life and also supports economic development. For this reason,these design guidelines are provided as a means of protecting historic resources and promoting compatible new construction within their context. This document presents Design Guidelines for the City and Borough of Seward's Downtown Historic District.They offer criteria for determining the appropriateness of improvements.

West View of 4th Avenue in June 1923. July 2019 A view looking west along 41h Avenue,as it appeared over a hundred and fifteen year period illustrates a moderate pace of change. Many early buildings survive,and others from the mid-Twentieth Century have also taken on historic significance. These"newer" buildings reflect their own times,in terms of style, but are compatible with their older neighbors, because they share basic similarities of design at a more fundamental level.These features are addressed in the design guidelines for new construction that appear in this document. Introduction i Version Date:October9,2019 What are Design Guidelines? Some of the guidelines are written specifically to be used when improving historic structures,others apply to non-contributing,existing — buildings, and still others apply to completely new ,"infill," construction. Why have Design Guidelines? Design Guidelines help establish a common understanding of preserva- tion principles and standards. Retaining the historic character that exists downtown is an important goal for Seward. The historic resources of Seward are vulnerable to inappropriate alteration and demolition. These resources are key parts of the community's identity, livability and,through heritage tourism, its economy as well. Who uses the Design Guidelines? These Design Guidelines have been written primarily for use by the Citizens of Seward and are recommended by the Historic Preservation of the City of Seward. The guidelines are also intended for use by property owners in making decisions about proposed �I �+lull rehabilitation and new construction projects that will be sensitive to the historic character of the district and individual landmarks. While they are focused on the desig- nated Downtown Historic District, the Design Guidelines also may be applied to key historic structures outside of the district that may be designated by the City. i. e. Jesse Lee Home. Introduction i Version Date:October9,2019 When to use the Design Guidelines The Design Guidelines should be consulted for projects which may affect the integrity of historic resources. While ordinary repair and maintenance is appropriate,seemingly minor alterations to a historic structure,such as enclosing a storefront or changing windows, can have a dramatic effect on the character of a historic structure and therefore,are of concern.The following is a list of common changes that can have a significant impact on the integrity of a historic structure: 4 Construction of a new addition 4 Alteration or restoration of exterior features of a historic building 4 Removal or demolition, in whole or in part, of a historic building 4 Alteration of a storefront 4 Application of a new exterior siding material Addition ofa new window or door opening 4 Creation of a driveway or a parking area 4 Construction or addition of a parking deck 4 Application of architectural features and other miscellaneous modifications, such as cornices and bulkheads. This list is not all inclusive, but is indicatleof the types of changes to which these Design Guidelines apply. For questions regarding permits and the applicability of these guidelines, please contact the City and Borough of Seward's Building Department. Where do the Design Guidelines apply? The Design Guidelines apply to properties within the Downtown Historic District, as shown on the enclosed map. These guidelines are also applicable to individual historic properties outside of the historic district designated by the City of Seward. Introduction iii Version Date:October9,2019 Compliance with the Guidelines Development within the Downtown Historic District shall comply with all of the relevant guidelines. In some cases,there may be an interaction among the relevant guidelines. This shall be determined by the review process with appropriate committees, to not restrict development or add an unnecessary burden to the property owners. Relation to Land Use Code These Downtown Historic District Design Standards and Guidelines comprise regulations adopted pursuant to Seward's existing zoning and building codes. Do Design Guidelines dictate taste? The guide lines reflect basic approaches to design that will help preserve the historic integrity of the district. They do not dictate style, but they do require compatibility with the historic character of the district. They also reflect the values of the community, including it's goals to preserve the historic buildings and character of Downtown Seward.

Then, a specific approach to the overall treatment of the property should be established.This may include keeping the building in its current character, while making appropriate repairs, or also incorporating new, compatible changes. It is then important to determine how surviving historic features will be treated.This may include preserving those features that remain intact, repairing those that are deteriorated and replacing others.These steps in planning a preservation project are presented in this section. First you must determine your building type: Historic Building New Construction See Chapters 7- 10 Step 1: Conduct Historic Research. Non-Contributing See Page ix Step 2: Determine Historic Integrity. Contributing or Non-Contributing Step 3: Identify Key Features. V Step 4: Choose an Approach. IF Step 5: Choose a Treatment.

An early question is: does the building date Identifying the Visual Aspects of Historic from the period of significance for the district? The method of Buildings as an Aid r Preserving Their p g ' Character,for further information. construction, the historic uses and other unique features will influence which preservation approach is most appropriate. Useful materials to investigate a building's history include Sanborn Maps, historic photos and written histories of Seward. Good starting ` places to obtain historic building information are the Community Development Department, Resurrection Bay Historic Museum, State Historical Library and the Historic Commission for the City of Seward. ,. Step 2: Determine Historic Integrity. Buildings with integrity have a sufficient percentage of structure exhibiting characteristics from the period of significance, which is identified in a Survey of Historic Resources by the Seward Historic Commission in the Seward Downtown Historic District. The majority of , a building's structural system and its materials should date from that �h+�IIIII111�I�� t� time and its key character-defining features also should remain and the overall mass and form of the building. These key elements allow a - building to be recognized as a product of its time. Typically a building with a high degree of historic integrity qualifies as a "contributing" property to the district. Others have lost their integrity and are termed Non'- „ "non-contributing." Contributing Property Contributing properties form the foundation of the historic district, and .= are either individually eligible for the National Register or clearly 1�IIuII�hII; contribute to the district's historic character.These are buildings that are in comparatively original condition; some have minor alterations and others have been appropriately restored. These buildings might still be improved by some further restoration efforts. Information on buildings that are identified as "Contributing" by Seward is available to the A building has historic integrity when public. it maintains its original character-de- fining features, structural system and Often, a property may also be considered contributing if it has one or building materials. A comparison of more of the following attributes: historic (early 20th century) and con- Has character, interest or value as part of the local, regional,state temporary (2019) photographs or national history, heritage or culture; demonstrates that this building retains Is the site of a significant historic event; a high degree of integrity. 4 Is identified with a person or persons who significantly contributed to the local, regional, state or national culture and history; 4 Exemplifies the cultural, economic, social or historic heritage of the community; 4 Represents a distinctive architectural era; 4 Embodies the distinguishing characteristics of an architectural 4 type or specimen; Introduction vii Version Date:October9,2019 4 Includes the work of an architect, engineer or master builder whose individual work has influenced the development of the community; 4 Embodies elements of architectural or engineering design, detail, materials or craftsmanship which represent a significant architectural innovation or which is unique. The guidelines for rehabilitation shall apply to all contributing proper- ties. Non-Contributing Property There are other buildings that exist within the boundaries of the historic district that do not contribute to its significance. Some of these are ones that have a nearly construction date, but have been so substantially altered that they no longer convey the historic character and these later alterations have no significance in themselves. Other properties are ones that are more recent, and therefore have not taken on historic significance. Many of these are still "compatible"with the character of the district, but are not "contributors" in terms of the history of the area. Therefore,there are two types of"non-contributing" properties: (1) Older structures that have lost their integrity, and (2) new buildings that are not within the period of significance for the district. When reviewing improvements to non-contributing properties, preservation approaches are not required. What is important is that any alterations be compatible with the character of the district, just as any new, infill construction should be. Therefore, the guidelines for New Construction shall apply to all Non-Contributing Properties. II 1 This building was constructed later than the historic period of significance. It isconsidered a "non-contributing" i property. u Introduction vii Version Date:October9,2019 Differing Degrees of Integrity Roof Cornice Original Intact: High Degree of Integrity with brackets Double-hung windows Clerestory Windows Display Windows Recessed Entry This property retains a high degree of integrity: most of the original features and materials survive.

Introduction ix Version Date:October9,2019 Step 3: Identify Key Features. If the property is determined to be a contributor to the district,then it is important to identify which features are significant. This will help determine to what degree the property should be preserved as it is, or where there may be opportunities for compatible alterations tooccur. Step 4: Choose an Approach for Improvement. Preservation projects may include a range of activities, such as maintenance of existing historic elements, repairs of deteriorated materials,the replacement of missing features and construction of new additions. The following is a list of approaches that are appropriate for contributing properties: 4 Preservation. "Preservation" is the act or process of applying measuresto sustain the existingform,integrityand material of building. Some work focuses on keeping a property in good working condition by repairing features as soon as deterioration becomes apparent, using procedures that retain the original character and finish of the features. Property owners are strongly encouraged to maintain properties in good condition. 4 Rehabilitation. "Rehabilitation" is the process of returning a property to a state that makes a contemporary us possible while still preserving those portions or features of the property which are significant to its historical, architectural and cultural values. Rehabilitation may include a change in use of the building or additions. 4 Restoration. "Restoration" reproduces the appearance of a building exactly as it looked at a particular moment in time .This process may include the removal of later work or the replacement of missing historic features. 4 Reconstruction. "Reconstruction" of a building means rebuilding a structure, or a portion of one, that no longer exists exactly as it appeared historically. Introduction x Version Date:October9,2019 Step 5: Choosing a Treatment for Building Components. Selecting an appropriate treatment for specific building components of contributing properties will provide for proper preservation of significant features.The treatment options are presented in order of preference. In making a selection,follow this sequence: 1. Preserve: If a feature is intact and in good condition, maintain it as such. 2. Repair: If the feature is deteriorated or damaged, repair it to its original condition. 3. Replace: If it is not feasible to repair the feature, then replace it with one that is the same or similar in character(e.g., materials, detail,finish) to the original one. Replace only that portion which is beyond repair. 4. Reconstruct: If the feature is missing entirely, reconstruct it from appropriate evidence. 5. New feature or addition: If a new feature or addition is necessary, design it in such a way as to minimize the impact on original features. It is also important to distinguish new features from original historic elements. sue. TI IIIIiSi'llll i 'i IUSW'61R9 E:':. This contemporary addition to a historic building is appropriate. The addition is set back for the street facade,minimizing the impact on the existing structure. The materials on the addition are also distinguishable from the historic fabric and clearly read as a product of its time. Introduction xi Version Date:October9,2019 Alterations Many historic structures have experienced alterations as tastes changed or the need for additional space occurred. Early alterations typically were subordinate in scale and character to the main building and were often executed using materials similar to those used historically. Some early alterations may have historic value of their own In contrast, recent alterations usually have no historic value. Alterations are anticipated to continue. It is important that new alterations be designed in a manner compatible with the historic character of the building and implemented without damaging the historic fabric. Introduction xi Version Date:October9,2019 Criteria For Replacing Historic Features If original is missing... If a historic structure has been altered, what is the appropriate approach for its treatment? When a historically significant building has an important, character defining feature that is deteriorated, altered or missing, it is clear that the feature should be repaired or, if repair is impossible, it should be replaced with materials that are similar to that which existed historically, L 7-17:! to maintain the integrity of the building. Sometimes, under certain Two options may be circumstances, replacing the missing feature or alteration with considered: contemporary but compatible new features might be appropriate Thus there are two treatments which could be appropriate for repairing or replacing missing or altered features: Option A: Reconstruct the historic design.This is the referred ' p g p � treatment. 4 Option B: Replace the missing or altered feature with a contemporary but compatible new feature. The original details may be recon- structed, if good evidence is available. This is the preferred treatment. I W I,wmiiv Irmwat-Foll— A simplified version of the original may be considered.Be sure to use the major lines of the original detail. Introduction xiii Version Date:October9,2019 The review authority must determine which option (A or B) is appropriate when evaluating proposals for the replacement of deteriorated, non- historic alterations or missing historic features on historic buildings in Seward. There are three main criteria that will be considered when handling these types of situations: First, what is the significance of the building? If the building has a high level of significance, then reconstruction is preferred. If the building is contributing to the historic sense of the street but is not landmark quality, then more flexibility maybe allowed. Either replacing the feature using Option A and B can be considered. 4 Second, to what degree has the building retained its historic integrity and how important is the missing or altered feature to conveying the historic character of the building? If the building has retained a high degree of its historic integrity and the missing feature is important to the building's character, then it should be reconstructed. If the building has been substantially altered,then blOptions A and B described above can be considered. 4 Third, what is the quality of information about the historic features of the building? This criterion addresses the practical issue of whether or not the historic features literally can be replaced or replicated. There may not be sufficient information available about the historic feature to be confident that it can be replaced accurately.

Design Element Topic The guidelines are grouped into pertinent design element categories (e.g., site planning, building materials, store fronts).

This, then forms the base for preservation policies in the community. +" Orlander Building Basic Principles of Historic Preservation xv Version Date:October9,2019 Benefits of Preserving Historic Buildings Construction Quality Many of the buildings in Downtown Seward were constructed with care. These buildings were thoughtfully detailed with high quality finishes- - . features that owners today appreciate. The high quality of construction in historic structures is therefore a "value" for both the building owner F and the community. Livability and Quality of Life A physical sense of identity can reinforce desirable community social patterns and contribute to a sense of security. When groups of commercial buildings complement each other in their historic context, they create a street scene that is "pedestrian friendly," which encourages walking and neighborly interaction. Decorative architectural features and distinct architectural styles also contribute to a sense of identity, an attribute that is rare and difficult to achieve in newer areas of the city. Tourists are noting that Seward is one of the last truly Alaska towns. Economic Incentives These programs include the National Trust Loans Fund (NTLF), National Trust Community Investment Corporation, and the National Preservation Endowment. The NTLF consists of the Inner-City Ventures Fund (ICVF) and the National Preservation Loan Fund (NPLF). The NPLF provides funding to a spectrum of projects including the rehabilitation of historic buildings and sites. The National Community Investment Corporation makes equity investments in real estate projects that qualify for federal historic tax credits and when available state historic tax credits and New Market Tax Credits. The National Preservation Endowment provides funds to nonprofit organizations and public agencies.The funds offered can be utilized for preservation planning and educational efforts as well as intervention funds for emergency preservation projects. Please contact the NTHP for specific information regarding these and other preservation funding opportunities. There is also a Federal Rehabilitation Tax Credit;the program is managed by the National Parks Service and Internal Revenue Service in partnership with State Historic Preservation Offices. The federal government makes available a 20% income tax credit for certified rehabilitation projects that are National Historic Landmarks listed on the National Register, and that contribute to the National Register Historic District and certain local historic districts. These are only available to income-producing properties. Contact the City of Seward Historic preservation planner to discuss possible funding options. In some cases, owners also may donate a facade easement and take a charitable gift donation. The City of Seward may offer some incentives for restoration of these properties.. Basic Principles of Historic Preservation 2 Version Date:October9,2019 Economic Benefits to the Community Historic structures are irreplaceable.They bestow an identity and provide a tangible history of a place.These qualities make them highly desirable to both members of the community and property owners. Maintaining the historic character of the district encourages heritage tourism which is an important part of the local economy. . Studies show that each dollar spent on a rehabilitation project Ire continues to circulate in the local economy five to seven times, which helps support other businesses. (Rehabilitation projects also contribute more to the local economy than do new building programs because each �- dollar spent on a preservation project has a higher percentage devoted to local labor). By contrast, new construction typically has a higher percentage of each dollar spent devoted to materials that are produced outside of the local economy. Therefore, when money is The first step in planning a spent on rehabilitating a building, it has a higher "multiplier effect," preservation project is to identify keeping more money in the local economy. and maintain significant features and materials. Responsibility of Ownership Ownership of a historic property carries a responsibility to respect the historic character of the property and its setting. Ultimately, residents and property owners should recognize that historic preservation is a long- range community objective, that promotes economic well-being and overall viability of the community at large. vilm sw Heritage tourism is an important part of the local economy, and therefore preserving historic structures is important because it enhances the appeal of the city to visitors. Visitors continue to amaze they have finally found one of Alaska's original towns. Basic Principles of Historic Preservation 3 Version Date:October9,2019 Basic Principles for Non- ° Contributing Buildings and New Construction There are structures in the historic district that are non-contributing and othersites where new infill construction will occur. For these situations, the focus of design should be on being compatible with the historic context,andnotontheprinciplesfortreatmentofahistoricpropertythat are outlined earlier in this section. More flexibility is afforded to these sites, in terms of the details of design, when they respect the overall relationships of building mass, form, materials, scale and setting. New construction in the historic district The historic district remains a vital place that is mostly built, but there are should maintain characteristics of the still opportunities for new development within its boundaries. Designing district while being distinguishable as a building to fit within the historic district requires careful thought. It is new construction. important to realize that while a historic district conveys a certain sense of time and place associated with its history, it is also dynamic The following principles apply: V' r 1. Respect the design character of the nearby historic properties. Don't try to make a new building look older than it is. Thecopying ..rr or exact replication of architectural styles or specific historic buildings is discouraged. Often, a contemporary interpretation of I those architectural styles seen historically will work best. 2. Maintain the setbacks and alignments of buildings in the surrounding context An important principle for new • 1 construction is to maintain the uniform setback and alignment of buildings 3. Relate to the scale of nearby historic buildings. in a block. A new building shall relate at the street level to the general size, shape and proportions of historic buildings. . Basic Principles of Historic Preservation 4 Version Date:October9,2019 Rather than imitating older buildings, a new design shall relate to the traditional design characteristics of the area while also reflecting the architecture of its time. New construction may do so by drawing upon some basic building features—such as the way in which a building is located on its site,the manner in which it relates to the street,and its basic mass,form and materials—rather than applying detailing which may or may not have been historically appropriate.Therefore, it is possible to be compatible with the historic context while also producing a design that is distinguishable as being newer. Basic Principles of Historic Preservation 5 Version Date:October9,2019 Period of Significance In most cases, a property is significant because it represents or is associated with a particular period in its history. Frequently,this begins with the construction of the building and continues through the peak of its early occupation. Building fabric and features that date from the period of significance typically contribute to the character of the structure. The Downtown Seward Historic District has a period of significance which spans 50 years (1903- 1953).Throughout this period of significance,the district has been witness to a number of buildings and additions which have become an integral part of the area. Conversely, several structures have been built or alterations have been made after this period which are generally considered non-historic and may be considered for removal or replacement. In general keep this in mind: Early alterations,additions or new construction (more than 50 years old) may have become historically significant and thus merit preservation. Many additions or alterations to buildings and districts that have taken place in the course of time are themselves evidence of the history of the building and its neighborhood and therefore may merit preservation. More recent alterations, additions or new construction that are not historically significant may be removed. 4 For example, asphalt, aluminum, vinyl or other synthetic siding may presently obscure the original siding. In this case, removal of this alteration and restoration of the original material is appropriate and strongly encouraged. 4 Most alterations less than fifty years old lack historic significance. B& H pictures would be good ;; y ' .r here with red brick Some recent additions detract from the character of a historic building and may obscure significant features. In this case,the first floor character has been altered. Because the upper portion 21 retains a high degree of integrity with distinctive detailing, restoration of the original first floor should be considered. �.

Some other historic buildings do not fall into any specific architectural style, but they tend to have similar characteristics which help to define the downtown's unique historic character. These characteristics include wooden storefront windows on the first floor, double hung windows on the upper stories, flat roofs and canopies over the street fronts.

October . • • r� History • Character of Downtown Historic Version Date:October9,2019 Chapter 3 Design Guidelines for Rehabilitation of Historic Properties This chapter presents design guidelines for the treatment of historic properties in Seward's Downtown Historic District. The guidelines are based on a "three level" approach: the first level is to preserve existing historic features,the next level is to repair deteriorating features,then, if r features are beyond repair,the final level is to replace those features in kind. This three-step sequence of treatments reflects the principles outlined in Chapter 1, in which the least intervention for a historic component is preferred.These basic guidelines for rehabilitation apply to the - property as a whole, as well as to individual building components. Further guidance about building elements is provided in subsequent chapters.

Employ preventive measures such as rust removal, caulking, limited paint removal and reapplication of paint. These should not harm the historic materials. 4 Maintain key character-defining features. 4 Do not remove or alter architectural details that are in good condition or that can be repaired. Design Guidelines for Rehabilitation of Historic Properties 23 Version Date:October9,2019 3.2 Avoid adding elements or details that were not part of the original building. For example, details such as decorative millwork from a Late Victorian style should not be added to an Art Deco building. y , 3.3 Protect architectural details from moisture accumulation that may cause damage. Regularly check details that have surfaces which can hold moisture for long periods of time. This is especially important ��. along cornices and parapets. 3.4 Maintain original siding materials. When disassembly of a historic feature Using any material, either synthetic or conventional, to cover is required in a restoration historic material is inappropriate. Doing so would obscure the procedure, document its location so original character and change the dimensions of walls, which are that it may be repositioned particularly noticeable around door and window openings. The accurately. extra layer also could hide or cause further decay. If a property already has a non-historic building material covering the original, it is inappropriate to add another layer of new material, which would further obscure the original. Removing the covering is recommended. 3.5 Preserve original materials that show signs of wear rather than replace them when feasible. 4 All materials weather overtime and 4 Scarred finish does not represent an inferior material, but simply reflects the history and age of the building, and should be accepted as a part of the character of a historic resource. Repair In some cases, original architectural details may be deteriorated. Horizontal surfaces and windowsills are likely to show the most deterioration because they are more exposed to weather. When deterioration occurs, repair the material and any other related problems. Replacing a feature is inappropriate, when it can be repaired instead. 3.6 Repair deteriorated primary building materials by patching, piecing-in, consolidating or otherwise reinforcing the material. 4 Repair only those features 4 That are deteriorated, and a void the removal of damaged materials that can be repaired. 4 Isolated areas of damage may be stabilized or fixed. Epoxies and resins may be considered for wood repair and special masonry repair components also may be used. 4 Patch, piece-in, splice, consolidate or otherwise upgrade existing materials using recognized preservation methods. 4 Protect features adjacent to the area being worked on. 4 Employ treatments such as rust removal, caulking, limited paint removal and reapplication of paint or stain. Design Guidelines for Rehabilitation of Historic Properties 24 Version Date:October9,2019 3.7 Plan repainting carefully. Always prepare a good substrate. Remove damaged or deteriorated paint only to the next intact layer, using the gentlest means possible, prior to painting. Use compatible paints. Some latex paints will not bond well to earlier oil-based paints without a primer coat. 3.8 When disassembly of a historic element is necessary for its restoration, use methods that minimize damage to the original materials. _ When disassembly of a historic feature is required during restoration document its location so it may be repositioned "'— accurately. Always devise methods of replacing disassembled details in their original configuration. 3.9 Use technical procedures for cleaning, refinishing and repairing architectural details that will maintain the original finish. 4 When choosing preservation treatments, use the gentlest means Early 20th century. possible that will achieve the desired results. 4 Perform a test patch to determine that the cleaning method will cause no damage to the material surface. Many procedures can actually have an unanticipated negative effect upon building materials and result in accelerated deterioration or loss of character. Harsh cleaning methods, such as sandblasting, can damage the historic materials, changing their appearance. Such proced s _ are inappropriate and should be avoided. 4 If cleaning is appropriate, a low pressure water wash is preferred. �- Chemical cleaning may be considered if a test patch is first reviewed and negative effects are not found. �9 Replace 2006. While restoration of an original feature is the preferred alternative, in- kind replacement is an option when repair is not feasible. When the = original material must be replaced, using the same material as the original is preferred, but an alternative material may be considered i when it conveys characteristics similar to the original. " '`` 3.10 Replacement of an original feature should occur only if the material is beyond repair. Repairing the original is preferred, because it will maintain the integrity of the property. 3.11 Replace only the amount needed. - For example, if a few boards of lap siding are beyond repair,then only they should be replaced, not the entire wall. In-kind replacement,as seen on the roof shingles above in 2007, is an option. Design Guidelines for Rehabilitation of Historic Properties 25 Version Date:October9,2019 Replacement 3.12 Replacement of missing or deteriorated architectural elements piece should be accurate. 4 The design should be substantiated by physical or pictorial evidence to avoid creating a misrepresentation of the building's history. 4 Use the same kind of material as the original when feasible. A substitute material may be appropriate if the size, scale, shape, texture, color and finish (composition) conveys the visual appearance of the original. For example, if the original material is wood clapboard, then the replacement material should be wood Where replacement of an element is as well, matching the original in size, the amount of exposed lap required, remove only those portions and in finish. that are deteriorated beyond repair. Primary building materials, such as wood siding and concrete, shall not be replaced with synthetic materials. 3.13 When reconstruction of an element is impossible, develop a new i_ _ . _ t__t- a-T_ design that is a simplified interpretation of it.

For example, asphalt siding that covers original wood siding should be removed. 4 Once the non-historic siding is removed, repair the original, underlying material. 4 In some cases removing a second finish may cause damage to the original and may not be desirable.Test the finish to assure that the original material underneath will not be permanently damaged. Protect and Maintain Property All historic properties in the Downtown Historic District should be maintained to prevent the need for more extensive repairs or replacement of building features in the future. Prolonged deferred maintenance results in "demolition by neglect." 3.15 Minimize the deterioration of a property. 4 Provide regular maintenance to a historic building and its site features in order to minimize the need to replace historic materials. 4 Maintain material through appropriate treatments such as caulking, limited paint removal and re-application of paint. 4 Maintain photographic documentation of the property for use in future preservation efforts.

Design Guidelines for Historic Building Materials 30 Version Date:October9,2019 Chapter 5 Design Guidelines for Historic Building Elements Individual building elements, including windows, doors, and cornices, can strongly affect the character of a building and the preservation and maintenance of the original elements is important. The following preservation guidelines apply to specific elements on historic properties. Windows The character-defining features of a historic window and its distinct materials and placement shall be preserved. In addition, a new window shall be in character with the historic building.This is especially important on primary facades and at street level. More flexibility is appropriate on non-street front walls and rear walls. 5.1 Preserve the functional and decorative features of a historic window. Features important to the character of a window include its frame, sash, muntins, mullions, glazing, sills, heads, jambs, moldings, ' `` operation and groupings of windows. Repair frames and sashes rather than replacing them,whenever conditions permit. 5.2 Preserve the position, number and arrangement of historic i windows in a building wall. 4 Enclosing a historic window opening in a key character-defining `- facade is inappropriate, as is adding a new window opening. This is especially important on primary facades where the historic ratio of solid-to-void is a character-defining feature. 4 Greater flexibility in installing new windows may be considered ri on rearwalls. 5.3 Preserve the size and proportion of a historic window opening. Reducing an original opening to accommodate a smaller window or increasing it to receive a larger window is inappropriate.

However, a substitute material components should match those of may be considered on secondary facades if the appearance of the original in dimension,profile the window components will match those of the original in and finish. dimension, profile and finish. Vinyl or aluminum clad windows may be considered on upper floors only if the original type of material is unavailable. The replacement must match the original's dimensions, detail and composition. 5.7 Match, as closely as possible, the profile of the sash and its components to that of the original window. A historic wood window may have a complex profile.Within the window's casing,the sash steps back to the plane of the glazing (glass) in several increments. These increments, which individually only measure in eighths or 4 quarters of inches, are important details. They distinguish the actual window from the surrounding plane of the wall. 5.8 Use a storm window to enhance energy conservation rather than replace a historic window. 4 Install a storm window on the interior, when feasible. This will allow the character of the original window to be seen from the public way. 4 If a storm window is to be installed on the exterior, match the sash design of the original windows. A metal storm window may be appropriate if the frame matches the proportions and profiles of the original window. It shall fit tightly with in the window opening without the need for sub-frames or panning around the Match, as closely as possible, the perimeter. Match the color of the storm window sash with the profile of the sash and its components color of the window frame; do not use an anodized or a to that of the original window. milled (a silvery metallic)finish.

The shadows created by traditional overhangs contribute to one's perception of the building's historic scale and provide weather protection; therefore, these overhangs should be preserved. Cutting back roof rafters and soffits or in other ways altering the traditional roof overhang is inappropriate. 5.23 Avoid using conjectural materials or features on a roof. Adding features such as a widow's walk (an ornate railing around the roof ridge) on buildings where there is no evidence that one existed creates a false impression of the building's original ti _ appearance, and is inappropriate.

Such an addition is usually similar in character to the original building in terms of materials,finishes and design. Adaptive Re-Use Converting a building to a new use that is different from that which its design reflects is considered to be "adaptive re-use." For example, converting a residential building to an office is adaptive re-use. A good adaptive re-use project retains the historic character of the building while accommodating its new function. 6.2 Seek uses that are compatible with the historic character of the building.

New buildings in the district must both respect the existing historic character of the district, while not creating a false sense of history in new structures that would damage the integrity of the district as a whole. Downtown Seward is not known for one specific historic period of significance, but rather developed over several periods of significance. As such, Seward has several different types of architectural styles, reflecting the times in which major phases of development took place. While no one style dominates, the majority of the buildings maintain similar qualities that serve to unify the visual quality of the district. New buildings shall follow the historic patterns of development in Seward by both reflecting the unifying visual qualities and character-defining features of the district, and by reflecting the time in which they are built. The following guidelines apply to new buildings and to alterations of non-contributing buildings in the historic district. New construction shall respect the character-defining features of the historic district and reflect the time in which they are built.This new building uses traditional components, including storefronts, canopies and transoms. While they appear similar to historic ones, these are in fact contemporary interpretations,which is appropriate. Design Guidelines for New Construction 43 Placement and orientation Chapter 7 With the exception of small gaps in the building wall that occur for pedestrian or vehicular alleyways,most structures in the historic district are built to the full width of the parcel and to the front lot line. The resulting "street wall" pattern shall be maintained in newdevelopment. 7.1 Maintain the alignment of buildings at the sidewalk edge. 4 Locate the front street wall at the sidewalk line when feasible. 4 If the building has a modern interpretation of a storefront, it shall maintain the feel of the street wall through use of architectural elements and features at the street edge. 7.2 Street facades shall span lot widths. 4 Spaces between buildings shall be kept to a minimum to maintain the street wall and sense of enclosure at the sidewalk. 4 Exceptions are for access ways to side or rear entrances. 7.3 Lots that have multiple street fronts shall be built to address each street facade. 4 Buildings on corner lots shall be built to the sidewalk on both streets o the extent possible without interfering with public safety. 4 Buildings on lots which face multiple streets shall be double fronted and bu i It to the sidewa I k at both street fronts. 4 Storefronts are appropriate along all street level facades of the buildings. 7.4 Buildings on angular lots shall be built to lot lines. The angular street pattern and the resulting non-rectilinear building forms are characteristics of Downtown Seward and new buildings may continue this pattern. Align the building front at the sidewalk edge. Building A is an inappropriate example of building placement along the sidewalk edge, since it does not align with the other buildings on the block. Building B is an appropriate example. Design Guidelines for New Construction 44 Mass, Scale and Height Patterns of building occur along the street by the repetition of similarly- _ _ -; =--- sized building elements. For example, uniform facade widths, evenly spaced along Front Street, create a rhythm that contributes to the visual continuity of the district. At a smaller size,the repetition of upper-story windows across most building fronts also creates a unifying effect. x These features and similar patterns are some of the most important characteristics of the district and shall be respected in all new construction. 7.5 Traditional spacing patterns created by the repetition of Example of new construction which uniform buildings widths along streets shall be maintained. would relate to existing historic 4 In most cases, a facade shall not exceed established widths without structures by maintaining the a clear expression of the historic pattern. alignment of horizontal features, Where a building must exceed this width,use a change in design producing a similar floor to floor features to suggest the traditional building widths.

Design Guidelines for New Construction 47 Architectural Character While it is important that new buildings and alterations become compatible with the historic context, they shall not imitate older building styles because this confuses the authenticity of the district. Visual compatibility results when the design variables in a new building are arranged to be similar to historic patterns in the area yet in ways that conveytheirown time. 7.13 New interpretations of traditional building styles are appropriate.

Canopies shall not be angled across the building facade. 4 Some slope is appropriate to allow for run-off of precipitation. 4 Articulation in awnings and canopies is appropriate to designate the main building entry. 7.23 Projecting horizontal canopies are most appropriate. The canopy shall fit the opening of the building. 4 Odd shapes, bull nose awnings and bubble awnings are inappropriate on most structures. 4 Internal illumination is inappropriate. Simple shed shapes may be considered in some cases. Design Guidelines for New Construction 50 Balconies Balconies may be provided as amenities where their use will not impact the integrity of the district. 7.24 Balconies may be considered on new structures where: 4 They will not directly be directly visible from the public right-of- way, such as on the rear of a building.

Sidewalk Street Rooftop use areas should not be visible from the sidewalk below. Design Guidelines for New Construction 51 Windows j A pattern exists along the streets with the repetition of evenly-spaced, similarly-sized, upper-story windows. These windows are often double hung, and help to give buildings a sense of human scale. Using window sizes and proportions that are familiar to the pedestrian helps them to jrelate to the overall size of a building.The alignment and similar scale of windows reflect a common historic pattern that shall be continued in new development. 7.26 Upper-story windows with a vertical emphasis are required. 4 A typical upper-story window is approximately twice as tall as it is wide.

The upper story windows are aligned higher then traditionally seen and the projecting central bay window and cornice are out of character. The display windows should be larger and be accompanied by kick plates. Design Guidelines for New Construction 52 Entries The repetition of recessed building entries occurring along the street in the historic district provides a rhythm of shadows along the street, which helps establish a sense of scale and invites pedestrians to enter buildings.This trend shall be continued in new construction. 7.29 A building entrance shall appear similar to those used historically. 4 Clearly define the primary entrance. 4 Recess the building entrance. 4 Choose a design similar in scale and overall character to those seen historically for a contemporary interpretation of a traditional building entry. 4 Place the primary building entrance at or near street level.

Design Guidelines for Site Design and the Public Streetscape 56 Building and Site Lighting The primary function of lighting is for safety and security. Lighting is also used to accent building character and for advertising and sales promotion. The primary goal for lighting in Seward is that it shall not be detrimental to the adjacent surroundings or the overall environment, but shall still maintain a safe environment. Lighting the sidewalk sufficiently is a goal within the district. This does not imply high levels of illumination; minimum illumination levels are more appropriate for various nighttime functions. The character and level of lighting that is used on a building is of special concern.Traditionally, exterior lights were simple in character and were used to highlight signs,entrances and first floor details. Most fixtures had f incandescent lamps that cast a color similar to daylight, were relatively =^ low in intensity and were shielded with simple shade devices.

Sign Composition The composition of a sign in contrast to a building's architectural detail and design are important to preserving the significance or integrity of a historic building. When designing and installing a sign the following Design Guidelines forSigns 66 shall apply: 10.6 Signsshall be subordinate to the overall building composition. 4 Scale signs to fit with the facade of the building. Locate a sign to emphasize design elements of the facade itself. Mount signage to fit within existing architectural features using the shape of the sign to help reinforce the horizontal lines of moldings and transoms seen on the building. Calculate the sign area by using simple geometric shapes that define the sign. 4 Though not widely done historically, the use of symbols to portray a word, name, or idea may be considered. 4 Rooftop signs are inappropriate. This includes stand-alone or painted on signs. j 10.7 A corporate logo or color scheme may be incorporated into signage as long as signs of this nature do not alter or destroy existing architectural features or details. The Community Development Department Director shall determine the portion of the building that will be recognized as part of a corporate design,and therefore a sign. An irregularly shaped sign area is calculated by a simple geometrical shape juxtaposed on the object.

Any sign that visually overpowers the building or obscures significant views or architectural features is inappropriate. ' 10.9 A simple sign design is preferred. Typefaces that are in keeping with those seen in historic photos or that are traditionally used are encouraged. Modern typefaces are inappropriate. Avoid hard-to-read or overly intricate typeface styles. Consider letter and painted signs on blank walls as theywere used historically. A sign shall be clearly legible. Sign Materials A sign's material shall reflect the style of the building to which it is attached and its period of significance (see Chapter 2). 10.10 Use signage materials that are compatible with the building facade. Signs shall be wood,sign-grade foam,or metal. 4 Other materials may be used as long as the material is durable and does not have a plastic appearance. 4 Signs shall be painted and shall have a matte surface finish. The use of vinyl covers or stickers are inappropriate, except in the instance of window and door signs. 4 Highly reflective materials shall not be used. Sign Lighting The sign illumination source shall be shielded to minimize glare. Light intensity shall not overpower the building or street edge. Small and discreet modern light fittings may provide an unobtrusive alternative totraditionally styled lamp units. 10.11 Use indirect lighting on signage. Directthe lighting at signage from an external,shielded lamp. 4 Warm lighting, similar to daylight, is appropriate. 4 Strobe lighting is inappropriate. 4 Internal illumination is inappropriate. 4 Halo illumination is inappropriate.

Sign Color J. The use of color in sign design shall be assessed in the context of the building, as well as the area, scale and form of the sign. Strong primary i colors shall be used sparingly and primarily for accent purposes. Sign panels shall avoid areas of white or cream, which visually detach the sign from the building. Color shall be used to accentuate the sign design and message, and to integrate the sign with the building. 10.13 Use colors forthe sign that are generally compatible with those Appropriate under canopy hanging of the building front. signs. 4 In general, no more than three main colors shall be used, although small amounts of additional accent colors may be appropriate. 4 Use colors and materials that are compatible with the overall color scheme of the facade 4 Select colors that offer contrast and legibility. Design Guidelines forSigns 69 arrb,itacotld(TT nd in minimizing damage to the building. UllDesign Guidelines for Off-season Display Windows Downtown Seward is a seasonal tourist destination; this creates occupancy issues because many businesses close during the off- season. Upon closing, tenants and/or business owners screen windows with butcher paper or similar types of materials to convey closure. This type of treatment has a negative impact on the streetscape, including a perception of abandonment. Exterior and interior lights are also extinguished, reinforcing the sense of closure along the street. A more appropriate approach is to consider installing a temporary window display that could block views to the interior of the store, but also convey information. For example, an interpretive photo display could be one approach that could solve this issue. Low levels of illumination could light the panels throughout the evening hours. Exterior lights that help to illuminate the sidewalk should also be maintained throughout the year. These efforts would enhance the streetscape and create a pedestrian-friendly environment year-round. 11.1 Display windows shall provide year-round interest. Windows covered by newspaper, boards or blank coverings are inappropriate (For example, a pictorial history of Seward or the building's past can be made for display during the off-season. This can take the form of banners or display boards.). ■ f � S r ■ Appendix A-73 Appendix A The Secretary of the Interior's Standards for the Rehabilitation of Historic Buildings The Secretary of the Interior's Standards for the Rehabilitation of Historic Buildings are general rehabilitation guidelines established by the National Park Service.These standards are policies that serve as a basis for the design principles presented in this document.The Secretary's Standards state that: 1. A property shall be used as it was historically or be given a new use that requires minimal change to its distinctive materials, features, spaces, and spatial relationships. 2. The historic character of a property shall be retained and preserved. The removal of distinctive materials or alteration of features, spaces, and spatial relationships that characterize a property shall be avoided. 3. Each property shall be recognized as a physical record of its time, place, and use. Changes that create a false sense of historical development, such as adding conjectural features or elements from other historic properties, shall not be undertaken. 4. Changes to a property that have acquired historic significance in theirown right shall be retained and preserved. 5. Distinctive materials, features,finishes, and construction techniques or examples of craftsmanship that characterize a property shall be preserved. 6. Deteriorated historic features shall be repaired ratherthan replaced. Where the severity of deterioration requires replacement of a distinctive feature,the new feature shall match the old in design, color,texture, and,where possible, materials. Replacement of missing features shall be substantiated by documentary and physical evidence. 7. Chemical or physical treatments, if appropriate, shall be undertaken using the gentlest means possible. Treatments that cause damage to historic materials shall not be used. 8. Archeological resources shall be protected and preserved in place. If such resources must be disturbed, mitigation measures shall be undertaken. Appendix A-73 9. New additions, exterior alterations,or related new construction shall not destroy historic materials, features, and spatial relationships that characterize the property.The new work shall be differentiated from the old and shall be compatible with the historic materials,features, size, scale and proportion, and massing to protect the integrity of the property and its environment. 10. New additions and adjacent or related new construction shall be 11. Under taken in such a manner that, if removed in the future, the essential form and integrity of the historic property and its environment would be unimpaired. Design for alterations and additions to existing properties should not be discouraged when such alterations and additions do not destroy significant historical, architectural or cultural material. Such design should be compatible with the size, scale, color, material and character of the property, neighborhood and environment. Appendix A-2 Appendix B Historic Preservation Briefs The Cultural Resources Department of the National Park Service, in the U.S. Department of the Interior, started a program in 1975 in which it has continued to publish a series of technical reports regarding proper preservation techniques. This series, Preservation Briefs, is a mainstay for many preservationists in the field. When considering a preservation project on any historic property these resources should be sought out.
