Existing house sq. ft.: 2,586 sq. ft. STAFF RECOMMENDATION Staff recommends the Landmarks Board approve the application with conditions. RECOMMENDED MOTION I move that the Landmarks Board adopts the staff memorandum dated February 3, 2021, as the findings of the board and, with conditions, approves the Landmark Alteration Certificate application to add a deck and replace Item 5B - 1740 Sunset Blvd. memo 2.3.2021 Page 1 of 36 windows at rear, replace chimney and paint brick at 1740 Sunset Blvd., an individual landmark as shown on plans dated January 6, 2021, finding that the proposal generally meets the Standards for Issuance of a Landmark Alteration Certificate in Chapter 9-11-18, B.R.C. 1981. Conditions of Approval 1. The applicant shall be responsible for completing the work in compliance with the approved plans dated January 6, 2021, except as modified by these conditions of approval. 2. Unpainted buff brick is a defining feature of the historic landmark and should not be painted per the National Park Services Technical Services program recommendations https://www.nps.gov/tps/standards/rehabilitation/rehab/masonry01.htm. Final approval is contingent on the brick not being painted. 3. Reduction in the amount of glazed to wall area at the south elevation to be more in keeping with the existing proportions – this may be achieved by reducing the height of the openings; revise design to use steel or metal clad windows and doors at south; maintain brick sills at all windows; redesign of the rear deck enclosure to a railing more characteristic of Ranch House design. 4. Prior to submitting a building permit application and final issuance of the Landmark Alteration Certificate, the applicant shall submit final architectural plans and specifications to the Landmarks design review committee (Ldrc), for its final review and approval to ensure that the final design of the building is consistent with the General Design Guidelines and the intent of this approval: a. Provide details for doors, including heights, materials, and finishes; materials and colors for deck railings; decking wood type and finish; deck support posts size, material and finish; chimney material type and color; roof materials and color. b. Provide details of panels shown on either side of glass doors. BACKGROUND AND SUMMARY • On December 22, 2020, the applicant submitted a landmark designation application for exterior changes at 1740 Sunset Blvd., an individual landmark. • LDRC reviewed the application on January 6, 2021, and referred the application to the Landmarks Board. • On January 6, 2021, the applicant submitted a revised application. • Staff finds that the proposal to add a deck and replace windows at rear, replace chimney and paint brick generally meets the Standards issuance of a Landmark Alteration Certificate pursuant to 9-11-18(a) & (b)(1)-(4) B.R.C. 1981 and is largely consistent with the General Design Guidelines. With the stated conditions, staff recommends approval by the Landmarks Board. EXISTING PROPERTY DESCRIPTION • The Reinert-Olson house is significant as a well-preserved example of owner-designed “ranch” house construction dating from the post WW-II period. • Significant features include a hip roof with wide overhanging eaves, buff brick, use of glass block and steel casement picture windows with a large-fixed center sash flanked by smaller steel casement windows. From the 2000 Landmark Designation memo: This buff brick residence with a basic “L-shape” is a typical representative of its type and period of construction. It features a hip roof with wide overhanging eaves over the main living portion of the house. A projecting two-car garage bay on the northwest corner of the house has a lower hip roof, also with wide overhanging eaves. Original garage doors are wood paneled, Item 5B - 1740 Sunset Blvd. memo 2.3.2021 Page 2 of 36 and each have two small windows. The garage has a glass block window on the east elevation. Other features typical of this period include original metal-frame windows. There are two large “picture” windows on the front elevation have a large, fixed center sash flanked by casements, and smaller panes above . . . … The rear elevation rises two stories in height due to the drop in elevation to the south, although this height is broken up with a roof eave on the lower level, which further emphasizes the horizontal appearance of the house. Two wings on either end of the house provide additional architectural interest, as well as frame a patio enclosure. Terraces form two patio areas in the rear yard. Figure 1.

Photograph Courtesy the Carnegie Branch Library for Local History Figure 4. 1740 Sunset Blvd., 2020 PROPERTY HISTORY • The house at 1740 Sunset Blvd. was constructed in 1950. With his wife Helen, George Reinert designed the property for his family, and then acted as general contractor for its construction. George’s father was a builder and is credited with construction of the Voegtle building on the northwest corner of Pearl Street and Broadway (a contributing building to the Downtown Historic District), and for many years operated the Reinert clothing store where George worked for a period of time. • At the time of its development, Sunset Hills was not seen as a stereotypical subdivision. Instead, it was a fresh approach to site planning, and by virtue of its prominent location, was proclaimed the fastest growing and most desirable neighborhood in all of Boulder in 1950. Item 5B - 1740 Sunset Blvd. memo 2.3.2021 Page 4 of 36 • The property changed ownership to Douglas McWeeny and Lois Fullop before being sold to Roger and Phyllis Olson for $30,000 in 1964. Roger Olson was elected to a two-year term as a City Council person in 1983. Phyllis Olson was an active member Historic Boulder, Inc. from 1974 until her death in 2020 and is responsible for the preservation of the Alan Faus house located at 1443 Spruce Street in Boulder. • In 1983, Phyllis began operating a bed and breakfast in the house and on January 2, 2001 the property was designated a local historic district landmark; the Reinert-Olson House. • The property was designated as an individual landmark for its significant association with the single-family residential development in the Sunset Hill subdivision; its architectural significance as an intact example if a custom-designed ranch house; and its environmental significance designed to take advantage of the singularly prominent views.

(b) Neither the Landmarks Board nor the City Council shall approve a Landmark Alteration Certificate unless it meets the following conditions: 1. Does the proposed application preserve, enhance, or restore, and not damage or destroy the exterior architectural features of the landmark or the subject property within a historic district? Staff finds that if the stated conditions of approval are met, the proposal will be consistent with the purposes of this chapter, in that the proposed modifications will not damage the exterior architectural features of property. 2. Does the proposed application adversely affect the special character or special historic, architectural, or aesthetic interest or value of the district? Staff finds that, if the conditions of approval are met, the proposal will not damage or destroy the historic character, interest, or value of the property or district as it will be generally compatible with the General Design Guidelines. 3. Is the architectural style, arrangement, texture, color, arrangement of color, and materials used on existing and proposed structures compatible with the character of the historic district? Staff finds that, if the conditions of approval are met, the architectural style, arrangement, texture, color, arrangement of color, and materials used will be compatible with the character of the landmarked site. (c) In determining whether to approve a Landmark Alteration Certificate, the Landmarks Board shall consider the economic feasibility of alternatives, incorporation of energy-efficient design and enhanced access for the disabled. Information specific to economic feasibly of alternatives, incorporation or energy-efficiency design and enhanced access for the disabled was not submitted with the application. DESIGN GUIDELINE ANALYSIS The Historic Preservation Ordinance sets forth the standards the Landmarks Board must apply when reviewing a request for a Landmark Alteration Certificate (LAC). The Board has adopted the General Design Guidelines to help interpret the ordinance. Design guidelines are intended to be used as an aid to appropriate design and not as a checklist of items for compliance. Item 5B - 1740 Sunset Blvd. memo 2.3.2021 Page 12 of 36 SUMMARY Staff finds that if the following changes are made, the proposed changes will be generally compatible and consistent with the standards set forth in Section 9-11-18 of the Boulder Revised Code and the General Design Guidelines for Boulder’s Historic Districts and Individual Landmarks. See Attachment A for a complete analysis of the proposal’s compliance with the design guidelines. GENERAL DESIGN GUIDELINES (SUMMARY) 3.2 Roof Decks and Balconies • Staff considers that the roof deck/balcony is compatible with the building and integrates into the existing structure but that the glass and steel deck enclosure should be redesigned to a railing more open and characteristic of early 1950 Ranch House design. 3.3 Decks • Staff considers that glass and steel deck enclosure should be redesigned to a railing more characteristic of early 1950 Ranch House design. 3.6 Exterior Materials: Walls, Siding, and Masonry • Staff considers that the unpainted buff brick is a defining feature of the house and should not be altered/damaged by painting per the National Park Services Technical Services program recommendations. 3.7 Windows • Staff considers that rehabilitation of the steel picture/casement windows on the north, east and west faces of the house is appropriate, but that new windows proposed on the south face should be reduced in height, made of steel (or metal clad) to be more in keeping with the historic windows, and that brick sills are defining features of the house and should be retained/reconstructed at all window openings. 3.8 Doors • Staff considers that the glass doors at the second level are over scaled and should be reduced in height and that they should be constructed of steel (or metal clad) to more closely match the historic windows on the house. 8.1 Paint and Paint Colors • Staff considers that the unpainted buff brick is a defining feature of the house and should not be altered by painting. See also 3.6 Exterior Materials. PUBLIC COMMENT Staff has received no public comment on this case. FINDINGS Staff finds that if the stated conditions are met, the proposed Landmark Alteration Certificate application to add a deck and replace windows at rear, replace chimney and paint brick at 1740 Sunset Blvd., an individual landmark will be generally consistent with purposes of the Historic Preservation Ordinance and generally Item 5B - 1740 Sunset Blvd. memo 2.3.2021 Page 13 of 36 meets the standards specified in Section 9-11-18 (b), B.R.C. 1981. The proposed work is also generally consistent with the General Design Guidelines. Staff recommends the Landmarks Board adopt the following findings: 1. The Landmarks Board finds that the project meets the standards for issuance of a Landmark Alteration Certificate set forth in Section 9-11-18, “Standards for Landmark Alteration Certificate Applications,” B.R.C. 1981. In reaching this conclusion, the Board considers the information in the staff memorandum dated February 3, 2021, and the evidence provided to the Board at its February 3, 2021 meeting. Specifically, the Board finds, if the stated conditions are met, that: 2. The proposed work will not damage the historic character of the landmark and is generally consistent with the General Design Guidelines. ATTACHMENTS Attachment A: Design Guideline Analysis Attachment B: Landmark Designation Ordinance (link) Attachment C: Applicant Materials Attachment D: Tax Assessor Card Item 5B - 1740 Sunset Blvd. memo 2.3.2021 Page 14 of 36 GENERAL DESIGN GUIDELINE ANALYSIS 3.0 ALTERATIONS The difference between “alteration” and “addition” (section 4) is in the magnitude of change to the original structure. Typically, an alteration is on a smaller scale than an addition. It usually involves elements such as adding dormers, decks, and windows. An addition usually means adding more square footage and/or external walls. As with an addition, an alteration should preserve and complement the historic character of the structure. It should not replicate but should be distinguishable from and simpler in design than any historic element. For example, an added window would not have the elegantly carved frames of a historic window. In general, simpler designs are the most successful. GUIDELINES: ANALYSIS: CONFORMS 3.2 ROOF DECKS AND BALCONIES Roof decks are deck areas above the first floor that are contained completely or partially in a roof mass. Balconies are railed or balustraded platforms that project from the building. Second story roof decks or balconies are characteristic of only a few architectural styles found in Boulder. They may be compatible additions, however, if located on the rear and if they are integrated into the primary structure. Second story roof decks or balconies are not appropriate for free-standing accessory buildings and garages. Any decks or balconies above the second story are inappropriate unless based on historic precedent. GUIDELINES: ANALYSIS: CONFORMS .1 Locate roof decks or balconies on the rear, not on the front, of the building. Front roof decks or balconies are appropriate only if recreating a documented historic element. The existing rear porch and roof appears original though is located on a secondary/tertiary elevation with limited visibility from Bluff Street. Proposed new deck/balcony is located at rear is and not visible from Sunset Blvd. And is generally compatible with the historic character of the landmark. Yes .2 Integrate the roof deck or balcony into the structure either by setting it into the building or by incorporating it into the roof structure. Roof deck/balcony replaces existing first floor roof and integrates well into the existing house. Yes .3 Avoid cantilevered projections from the building, and use appropriately scaled brackets or supports. Support posts should be appropriately visually sized. Resolve at LDRC. Yes .4 While current code requirements must be met, new railings should be as close as possible to historic heights. In addition, sensitive design may give the appearance of the lower railing heights found on historic structures. While there will be limited visibility from Bluff Street, proposed glass and steel balcony enclosure may be inconsistent with the simple Ranch House character. Consider using more traditional railing system more reflective of early 1950 Ranch House design. Maybe (Resolve at Ldrc, or staff) 3.3 DECKS Decks are modern expressions of porches that were not found on historic buildings. Great care needs to be taken in designing decks to fit into the historic character of the house. The design elements must respect the historic character as to size, materials, railing detail, intrusion into spaces between buildings, and materials. Because decks are not traditionally found on historic structures, they should be avoided or their appearance should be minimized. Decks should be subordinate to the house in terms of scale and detailing. For second story decks, see 3.2 Roof Decks and Balconies. GUIDELINES: ANALYSIS: CONFORMS .4 Materials with a synthetic look and/or feel should be avoided. Wood decking recommended - While there will be limited visibility from Bluff Street, proposed glass and steel balcony enclosure may be inconsistent with the simple Ranch House character. Consider using more traditional railing system more reflective of early 1950 Ranch House design.. Final approval of materials per LDRC. Maybe (Resolve at Ldrc, or staff) 3.6 EXTERIOR MATERIALS: WALLS, SIDING, AND MASONRY Brick, stone, horizontal wood-lapped siding, stucco, and wood shingles are common finish materials found in historic districts and on historic structures. Over the years, the materials used in residential construction have not changed dramatically, but the scale of materials has become larger. Narrower lap siding, smaller brick and shingles used alone or in various combinations often distinguish older homes from newer ones. Brick and stone masonry were traditionally left natural while wood surfaces were painted. GUIDELINES: ANALYSIS: CONFORMS Attachment A - Design Guideline Analysis for 1740 Sunset Blvd. Item 5B - 1740 Sunset Blvd. memo 2.3.2021 Page 15 of 36 .1 Original historic finish materials should be preserved and repaired. • Unpainted masonry surfaces, particularly those with historical significance, should not be painted. • When feasible, remove newer materials that have been applied over historic finishes and that have not achieved historic significance in their own right. Removal of non- historic materials such as stucco or permastone must be tested to assure that the original material will not be damaged in the process. • When repairing masonry use appropriate mortar, i.e., one that is softer than the surrounding masonry. Unpainted buff brick is a defining feature of the historic landmark and should not be painted consistent with the Secretary of the Interior’s standards for the Treatment of Masonry which recommends against the painting of unpainted brick for aesthetic and the risk of damage to the masonry https://www.nps.gov/tps/standards/rehabilitation/rehab/masonry01.htm. No .2 New finish materials should be compatible with, but not seek to replicate, original finish materials. • Use materials that are similar in scale, proportion, texture and finish to those used historically. • Use authentic materials - materials made to look like other materials, such as concrete that is scored to look like brick, are not appropriate. New roof section should match materials of existing roof (asphalt shingle). Final approval of roofing material for new section of roof and new chimney per LDRC. Yes 3.7 WINDOWS, STORM WINDOWS, AND SHUTTERS Windows, the elements that surround them, and their relationship to one another are one of the most important character-defining elements of a historic building and should be preserved. Improper or insensitive treatment of the windows on a historic structure can seriously detract from its architectural character. The relative importance of a window depends on three factors: the location of the window on the building, the historic significance of the window, and its condition. Windows on elevations visible from public ways, particularly the façade, are especially important. A window that has a high level of historic significance, regardless of its location, may also be very important to the historic integrity of the building. The replacement of historic windows or components including glass, should be considered only as a last resort. At times, property owners consider replacement of their historic windows as a way of improving energy efficiency. Research indicates that, in most cases, the energy efficiency of an old window can be increased to that of a thermal pane replacement window by weatherstripping, insulation of weight pockets, and the application of an interior or exterior storm system. While the energy loss of a building may be reduced by replacing or repairing historic windows, windows are only one factor in the building’s energy usage. It is strongly recommended that a comprehensive energy audit be undertaken to identify areas for improvement. To increase a building’s energy efficiency, a combination of air sealing, additional wall and ceiling insulation, and the adjustment of mechanical systems is generally more effective than focusing only on the repair or replacement of a window. For more information regarding energy efficiency and energy audits for historic buildings, please contact the Office of Environmental Affairs at www.environmentalaffairs.com GUIDELINES: ANALYSIS: CONFORMS Protection of Historic Windows .1 Retain and preserve existing historic windows, including their functional and decorative features, such as frames, glass, sashes, muntins, sills, heads, moldings, surrounds and hardware. Because windows near the façade are particularly critical to the character of historic buildings, their protection may supercede the protection of historic windows elsewhere. In some cases, it may be appropriate to use window elements from rear or side elevations to repair those on the front. Steel casement windows are specified to be rehabilitated and made weather-tight on the north, east and west faces of the house while windows on the south (secondary/tertiary) elevation of house are shown to be replaced with taller openings to be fitted with either glass doors or windows. The proposed changes to the face of the house will significantly alter the historic proportion of glazed area to wall area. Consider reducing the height of windows and doors to be more in scale with the historic/human scale of window openings on the house. Maybe (resolve at Ldrc) .2 Preserve original window locations; do not move windows from their historic placement. Brick sill is a defining feature of the house and should remain intact on all windows. No (resolve at the Ldrc) Attachment A - Design Guideline Analysis for 1740 Sunset Blvd. Item 5B - 1740 Sunset Blvd. memo 2.3.2021 Page 16 of 36 .3 Repair rather than replace the functional and decorative features of original windows through recognized preservation methods. If replacement of a feature is necessary, replace only the deteriorated feature in kind rather than the entire unit, matching the materials, design and dimensions of the original. Steel casement windows are specified to be rehabilitated and made weather-tight on the north, east and west faces of the house while windows on the south (secondary/tertiary) elevation of house are shown to be replaced with taller openings to be fitted with either glass doors or windows. Yes Retrofit of Historic Windows .4 In some cases, retrofitting historic windows to make them more energy efficient may be appropriate as part of a building rehabilitation program. Typically, a window retrofit preserves most or all of the historic wood, glass, or metal components and consists of insulating weight pockets and complete weather stripping of its sash and frames. If a window retrofit calls for the replacement of single pane glass, it is important to determine that the work will not compromise the historic character of the building or the district in which it is located. Steel casement windows are specified to be rehabilitated and made weather-tight on the north (primary), east and west (secondary), faces of the house. Yes Window Replacement .5 The replacement of historic windows should only be considered as a last resort if the fabric of the window is deteriorated beyond repair. However, if the property owner wishes to request a landmark alteration certificate to replace windows on a contributing or individually landmarked building, the steps as outlined in the Historic Window and Door Replacement/Retrofit Guidelines must be followed. Steel casement windows are specified to be rehabilitated and made weather-tight on the north (primary), east and west (secondary) faces of the house. Yes .6 The location of the window(s) proposed for retrofit or replacement is important in assessing their significance to a historic building. In general, the more important the elevation where the window is located, the less likely that retrofit or replacement will be appropriate. Elevations will be categorized as primary, secondary or tertiary, using the methodology set out in the Window & Door Replacement Application and Survey. • Replacement of intact historic windows on primary elevations is rarely appropriate. • Replacement of intact historic windows on secondary elevations is generally inappropriate. • Replacement of intact historic windows on tertiary elevations can occur provided it does not compromise the historic integrity of the building. Steel casement windows are specified to be rehabilitated and made weather-tight on the north (primary), east and west (secondary) faces of the house. Yes Attachment A - Design Guideline Analysis for 1740 Sunset Blvd. Item 5B - 1740 Sunset Blvd. memo 2.3.2021 Page 17 of 36 .7 The historic significance of the windows proposed for replacement must also be assessed. In general, the more significant a window is to the building as a whole, the less likely that a retrofit or replacement will be appropriate. The appropriateness of a window replacement will be determined, in part, based upon characterization of the window as either ‘Very Historically Important’, ‘Historically Important’, or ‘Non-Historic’ (See Definitions). Steel casement windows are specified to be rehabilitated and made weather-tight on the north (primary), east and west (secondary) faces of the house. Yes 3.8 DOORS AND STORM DOORS Front doors and primary entrances are among the most important elements of historic buildings. The original size and proportion of a front door, the details of the door, the door surround, and the placement of the door all contribute to the character of the entrance. Property Owners may wish to replace their historic doors to improve energy efficiency. Research indicates that, in most cases, however, the energy efficiency of an old door can be increased to that of a new replacement door by weather-stripping and the application of an interior or exterior storm door system. However, if a property owner wishes to request a landmark alteration certificate to replace doors on a contributing or individually landmarked building, the steps as outlined in the historic Window and Door Replacement/ Retrofit Application Guidelines must be followed. .8 Replace wood doors with wood doors. Synthetic materials are generally inappropriate. Synthetic materials rarely duplicate the surface texture, reflective and detail qualities of original materials. The use of materials matching the historic material is recommended. Staff recommends steel doors would be more appropriate to closely match the narrow frame profile of the original steel windows. Maybe (Resolve at staff or Ldrc) .10 Doors in additions and new structures should reflect the proportions (height and width) of doors in the existing structure and/or the district. 9’ foot doors seem out of scale with the existing. Consider reducing height of glass doors. Resolve at LDRC. Maybe (Resolve at staff or Ldrc) .11 Doors should be trimmed with materials similar in scale, proportion, finish, and character to those used traditionally. Details of panels on either side of glass doors not shown on plans. Provide details to LDRC. Maybe 8.0 MISCELLANEOUS 8.1 Paint and Paint Colors When renovating a historic building, first consider using the original color scheme. The original paint can often be discovered by careful analysis of samples of original materials. If it is not possible to discern original paint colors, a color scheme should be based on historic precedent within the area. The multiple, bright colors used in San Francisco, for instance, were not used in Boulder. Historically, paint colors were more muted tones than those used today because they depended upon a far more limited source of pigments. Most wood-clad buildings were painted entirely, generally with one base color and one or two additional accent colors on details and trim. For masonry structures, the natural color of the brick or stone was dominant; paint was applied to wood trim elements around doors and windows and in gable ends. s a practical matter, it is suggested that quart samples of the color scheme should be applied to a section of building as a test before making final selection. A color on a 1" x 1" paint chip will look different on a whole house. GUIDELINES: ANALYSIS: CONFORMS? .1 Preserve and protect original exterior building surfaces and site features that were painted by maintaining a sound paint film on them. Unpainted yellow/blonde brick is a defining feature of the historic landmark and should not be painted and should not be painted consistent with the Secretary of the Interior’s standards for the Treatment of Masonry which recommends against the painting of unpainted brick for aesthetic and the risk of damage to the masonry https://www.nps.gov/tps/standards/rehabilitation/rehab/masonry01.htm No .2 Original materials such as brick and stone that are unpainted should not be painted.

No 8.2 Energy Efficiency Attachment A - Design Guideline Analysis for 1740 Sunset Blvd. Item 5B - 1740 Sunset Blvd. memo 2.3.2021 Page 18 of 36 In 2006, Boulder’s City Council adopted a Climate Action Plan to meet the Kyoto Protocol goals of substantially lower emissions of greenhouse gases. It is the city’s aim to create compatibility between historic preservation and energy efficiency goals. In the historic districts and on individually landmarked buildings it is important to ensure that energy efficiency concerns are addressed in ways that do not damage or diminish the historic character of the building, site or district. It is recommended that before any energy efficiency upgrades are made a comprehensive energy audit is conducted to determine the building’s current energy loss. In historic districts, a variety of energy-conserving site and building features illustrate the sensibility of an earlier era to climate and energy efficiency. Thoughtfully located shade trees buffer residences and sidewalks from the summer sun. Projecting porches provide shaded outdoor space and lessen the impact of the harsh sunlight on the building's interior. Operable windows and shutters allow occupants to control the introduction of sunlight and breezes within the buildings. An understanding of how such historic features enhance energy efficiency is critical to maximizing the energy efficiency of historic buildings. For more information regarding the energy audit program and energy efficiency in historic buildings, please contact the Office of Environmental Affairs at www.environmentalaffairs.com.

No trees will be removed. Yes .2 Increase the thermal efficiency of historic buildings by observing traditional practices, such as weather-stripping and caulking, and by introducing appropriate energy efficient features, such as storm windows and doors.
