ARC 113-97 - A REQUEST TO RE-ROOF THREE BUILDINGS, INCLUDINGS THE HISTORICAL DALLIDET ADOBE AND THE RAMONA HOTEL RAILROAD DEPOT, LOCATED AT THE END OF PACIFIC council °'/0 j acEnaa REpoRt "® CITYOF SAN LUIS O B I S P O FROM: Arnold B.Jonas, Community Development Director ID Prepared By: Pam Ricci& Jeff Hook,Associate Planners SUBJECT: Appeal of Architectural Review Commission's approval of Project Application No. ARC 113-97 - a request to re-roof three buildings, including the historical Dallidet Adobe and the Ramona Hotel Railroad Depot, located at the end of Pacific Street adjacent to. San Luis Creek. CAO RECOMMENDATION Adopt Draft Resolution A, upholding the appeals of the Architectural Review Commission's action allowing composition shingles, and requiring new roofing materials to be wood shingles, either factory-treated with fire resistive chemicals or installed with an approved deluge sprinkler system, based on findings of consistency with the State Historical Building Code and the City and State's historical preservation guidelines. DISCUSSION Situation/Previous Review On August 25, 1997,the CHC reviewed the request and recommended that the Architectural Review Commission approve the seismic retrofit and find that the wood-shingle roof is a "character-defining feature" of the adobe and the depot, and further that the Architectural Review Commission work with the applicant to identify which material is most acceptable for maintaining the adobe's and the depot's historic integrity and appearance. Committee members expressed a preference for wood shingle replacement for historic integrity, but acknowledged that the action left open the possibility of another similar material being approved by the Architectural Review Commission On September 15, 1997, the ARC voted 5-0-1 to approve the use of composition shingles as the roofing material for the three buildings as requested by the Historical Society. The Commission found that that the composition shingles will provide superior fire safety for structures, allow for more efficient maintenance, and protect the buildings from further structural deterioration. The Commission qualified their action by acknowledging that the fire resistive wood shingles would be the.optimal solution and that the composition shingles were viewed as interim -solution. Several members of the Society spoke explaining the aesthetic, historical and budgetary factors that were considered in deciding on a suitable roofing material. Dallidet Re-roofing Appal(ARC 113-97) Page 2 Stan's Recommendation to the ARC Planning staff had recommended that the ARC require fire retardant wood shingles to replace the existing wood shake roofs for the three buildings. This recommendation was based on: 1) adopted standards in the City's Historical Preservation Program Guidelines; 2) the Cultural Heritage Committee's recommendation; and 3) staff's research on the buildings' historic context and appropriate treatments for historic adobe buildings. During discussions at the CHC and ARC meetings, all parties agreed that wood shakes or shingles are the most appropriate roofing material to maintain the historical and architectural integrity of the Dallidet Adobe and the Ramona Depot. Roofing material has a major effect on a building's appearance, and the use of historically inappropriate roof material will detract from an historic building's architectural character and integrity. The ARC's action to allow use of composition shingles was undoubtedly influenced by the Historical Society's statements that installation of wood shake or shingle roofing would pose an economic hardship for the organization. The Dallidet Adobe and Ramona Depot are two of the City's pre-eminent heritage buildings. They are distinctive remnants of important persons or events that shaped the City's history. As such, historic buildings are held to a high standard of architectural preservation to preserve their importance for future generations. Policy 6.6.2 of the General Plan Land Use Element states: "Historically or architecturally significant buildings should not be demolished or substantially changed in outward appearance, unless doing so is necessary to remove a threat to health and safety and other means to remove the threat are infeasible. " Cost factors alone are typically not a justification for developers to deviate from City standards. However, given that budgetary issues were raised at the ARC meeting, it may be useful to look at the actual costs involved. According to a roofing contractor, re-roofing with safe, fire-treated wood shingles would cost about $15,000; composition shingles would cost about one-half that amount. Community resources may be available through contributions, fund raisers, or grants to make up the roughly $7,000 difference in cost between composition and wood shingle roofs. While cost is a consideration, re-roofing with wood shingles would appear to be the most appropriate strategy from both an aesthetic and historical context standpoint, given the buildings' importance to the community and City preservation policies. Wood shingles would also be lighter than other alternative materials, like concrete shingles that can be made to.resemble wood, and would work with existing truss and roof support systems. However, the use of wood shingles seems to conflict with the City's fire protection strategies. The State Historical Building Code addresses this apparent conflict in goals with the use of wood shingles by providing the following two options: 1.) Fire retardant wood shingles: This alternative allows the use of the fire retardant wood shingles when they are installed as part of an approved and tested assembly. The fire Dallidet Re-roofing Appeiu(ARC 113-97) Page 3 resistive chemicals are applied to the shingles at the factory. Recent tests have shown that the fire resistant chemical treatment lasts for the roof's designated lifetime. 2.) Regular wood shingles equipped with a deluge water sprinkler system: Untreated wood shingles could be used if a sprinkler system was installed to allow the entire roof to be thoroughly saturated when activated. Note: For the purposes of this report and the attached resolutions, wood shingles also includes wood shakes. Appeals Received Three separate appeals of the ARC's decision were received, one on September 23'd and two on September 24". The chief objection of the ARC's decision contained in the appeals is that the approved composition shingles are not a historically convect material for the adobe and other structures. ALTERNATIVES 1. Adopt Draft Resolution B, denying the appeals of the ARC's action, and allowing the use of composition shingles as requested by the Historical Society, based on findings. 2. Continue with direction to the staff, applicant, and/or appellant.

Numerous public gatherings and private wedding receptions, memorials, and club meetings are held in the lovely garden. Unfortunately, every historical structure occasionally needs repair. The roof of the Dallidet Adobe is scheduled for renovation now in prep- aration for what we all believe will be a very wet winter. The repair of historic structures should be done with care- ful thought toward preserving the historic integrity and value of the building. The San Luis Obispo Cultural Heritage Commis- sion recently recommended unanimously that the present wood shingle roof be replaced with one of similar materials to preserve the historic integrity of the building. Wood shingles were, indeed, the historically correct roof covering. The Architect- ural Review Commission, I was astounded to hear, did not concur with this recommendation, leaving the door open for such horrendous alternative as tar paper or some other non-historical material. I am sure that members of the ARC would not have come to this conclusion if they had carefully considered the matter. I urge the Council to support the use of the historically correct wood shingles on the Dallidet Adobe. Sind Robert L.

The Cultural Heritage Commission has previously opposed the use of such a substitute material on the Dallidet, a registered State Historic Landmark(No. 720) since it was inconsistent with State of California regulations,as well as the Secretary of the Interior's Standards for Historic Preservation. Fire resistant roofing is available; though slightly more costly to install, it is compatible with preservation guidelines intended to preserve the appearance of these historic structures. The ARC decision may be defendable from solely an esthetic prespective but it is an uncomfortable precedent when judged against City historic guidelines and generally accepted Historic Preservation Guidelines. The City is working hard to preserve the character of the adobes it owns and should expect the same of other groups entrusted with the care of these historic structures. My hope is that in considering this appeal you will give both guidance concerning the narrow issue of roofing materials, as well as direction to the ARC concerning their use of applicable Standards for Historic Preservation in future deliberations.

Allen Settle, Mayor and City Council City of San Luis Obispo 990 Palm Street San Luis Obispo, CA Dear Council Members; On September 15, 1997 the Architectural Review Committee granted a variance to the San Luis Obispo Historical Society by allowing them to substitute a composition shingle roof on the Dallidet Adobe and other structures rather than the historically correct wooden shingle roof. Fire retardant wooden shingles are now approved by the Fire Department for use on historic structures, and the Historical Society has this information.. The Architectural Review Committee granted the variance based on a claim of hardship, thus overriding the unanimous recommendation of the Cultural Heritage Committee of maintaining historical accuracy with a wooden shingle roof. While the variance specifies this as a temporary solution, it does not indicate how long"temporary"is, and a composition shingle roof with a twenty-five year guarantee could hardly be categorized as temporary. It seems very inappropriate for an organization like the Historical Society, which should be protecting and sharing our historical heritage, to try to sidestep City Historical Guidelines as well as the Secretary of Interior Standards regarding historic properties. This will set a precedent that may well effect other historic properties in the city, both public and privately owned. My understanding is that the Historical Society has enough funds to allow for the historically accurate solution, but if they are claiming hardship, then I think they must open their books to review. The City in retrofitting and restoring the "Carnegie Library" is adhering to both the spirit and the letter of the Historic Guidelines. The action of the Architectural Review Committee now places the City in the contradictory position. As a member of the Historical Society as well as the Friends of las Casas de Adobe, I think this precedent will erode public confidence in that segment of our community which is working to restore these symbols of our history.

Pam Ricci, Associate Planner, presented the staff report, recommending approval of the seismic retrofit and re-roofing with the condition that new roofing materials be fire-retardant wood shingles, or other material that the ARC deems appropriate, rather than the proposed composition shingles, based on findings. Bob Vessely, representative, stated that he agrees that wood shingles would be the optimal roofing material selection. He also stated that he agrees with the CHC that wood shingles are a "character-defining" component of the structures. He noted that cost is an important factor in proposing to use composition shingles. He mentioned that the chemical treatment of fire retardant shingles makes them brittle. Carmen Simpson said she was concerned with the maintenance problems associated with wood shingles, especially with the amount of landscaping at the site. Bruce Collier stated he is concerned with fire safety issues. He noted that budget is a major consideration. ARC Minutes September 15, 1997 Page 2 Bud Mertens said aesthetic, historical and budgetary factors were all considered in choosing an appropriate material for roofing. He believed that thatch roofing was originally used on the adobe. He likes wood from an aesthetics standpoint.. Bob Vessely stated that the goal is to maintain and repair a functional building, rather than restore a historical artifact. He noted that they are not proposing changes that can't be undone.

SUMMARY RECOMMENDATION: Approve the seismic retrofit and re-roofing with the condition that new roofing materials be fire- retardant wood shingles, or other material that the ARC deems appropriate, rather than the proposed composition shingles, based on findings. BACKGROUND: Situation The San Luis Obispo County Historical Society owns and operates the Dallidet Adobe and gardens. The Society wants to replace the adobe's leaky wood shingle roof with composition shingles,and seismically strength the roof. The historic Ramona Hotel Depot and a public rest room,also on the grounds,are also slated for re-roofing. As explained in their letter, the Society wants to replace the roofs because they leak and are in poor condition. Also,the adobe roof supports are sagging and need to be strengthened and tied into the walls to preserve the structure during an earthquake. When the roof is off, the Society wants to seismically strengthen the roof/wall connection. The only visible change will be the change in roofing material from wood shingle to composition shingles. Composition shingles were selected because: 1) City codes prohibit the use of wood shake or shingle roofing (although an exception is possible for historic structures);2) composition shingles are expected to be longer lasting than a new wood shingle roof and have long-lasting fire resistance; and 3) a composition shingle roof is more economical to install and maintain. Previous Review Because the proposed re-roofing constitutes architectural changes which could change the appearance or historic significance of buildings on the City's Master List of Historic Resources, this request was referred to the Cultural Heritage Committee (CHC) for comment before the Architectural Review ARC 113-97 Page 2 Commission's review. On August 25, 1997,the CHC reviewed the request and recommended that the Architectural Review Commission approve the seismic retrofit and find that the wood-shingle roof is a "character-defining feature" of the adobe and the depot, and further that the Architectural Review Commission work with the applicant to identify which material is most acceptable for maintaining the adobe's and the depot's historic integrity and appearance. Committee members expressed a preference for wood shingle replacement for historic integrity, but acknowledged that the action left open the possibility of another material being approved by the Architectural Review Commission. The minutes from this meeting are attached to this report. Data Summary Address: 1185 Pacific Street Applicant: The San Luis Obispo County Historical Society Representative: Bob Vessely Zoning: O, Office General Plan: Offices Environmental Status: Categorically exempt under Class 1, Section 15301. of the CEQA Guidelines. Project Action Deadline: October 26, 1997 SiteBuildin Dg escription The Dallidet Adobe is one of the City's oldest and most significant historic structures,is eligible for the National Register of Historic Places,and has been designated a State Historic Landmark(#720). Located on 1 acre, the site is part of what once was a much larger homestead and vineyard owned by Pierre Hyppolite Dallidet. Mr. Dallidet was a farmer and vintner who arrived in San Luis Obispo from France in the mid 1850s. Later,the vineyard became the site of the Ramona Hotel railway depot,which served the street car line connecting the posh hotel with the railroad. Paul Dallidet, the senior Dallidet's youngest child of seven,deeded the family home to the Society in 1960. EVALUATION The Historical Society recognizes that the roof material change will constitute a change to the building's historic character;however after considering other roofing options,the Society believes that composition shingles would be the best all-around choice considering cost, appearance,fire resistance,maintenance, and historic character. Alternative materials considered include metal shingles or concrete tile (which resemble wood shakes) and fire-retardant wood shingles. Some of the alternative materials such as concrete tile are heavier and may pose structural problems with the existing truss systems of the buildings. The attached letter from Bob Vessely describes the proposed changes and the structural problems driving the request. There is no clear historic record of the adobe's original roofing. The current roof was probably installed in the 1960s;however remnants of an earlier,underlying roof suggest that the adobe's previous roofing was also wood shingle. Adobes dating back to 1850 would most likely have been roofed with clay tiles,wood shingles or shakes,corrugated tin, or rolled asphalt roofing. The Depot and Nc ARC 113-97 Page 3 rest rooms were probably built with wood shingle roofs. By the 1890s, individual slate, asphalt or asbestos shingles would also have been readily available. The City's Historic Preservation Program Guidelines address changes to Master List buildings. They state that "changes to the outside of a historic building should further promote its original architectural style and character"; and "Changes to the outside of such a building should not introduce some new or conflicting element and should complement the prevailing architecture of the surrounding area. Changes to parts of the a building that have been modified in the past should usually exhibit the building's original architectural style." The Guidelines encourage,but do not require,owners to follow the Secretary of the Interior's Standards of Historic Rehabilitation Projects. These standards state,in part: • "The distinguishing original qualities or character of a building,structure or site and its environment shall not be destroyed. The removal or alteration of any historic material or distinctive architectural feature should be avoided when possible."(emphasis added) • "Stabilization shall be accomplished in such a manner that it detracts as little as possible from the property's appearance. When reinforcement is required to reestablish structural stability, such work shall be concealed wherever possible so as not to intrude upon or detract from the.aesthetic and historical quality of the property, except where concealment would result in the alteration or destruction of historically significant material or spaces." The owners'options are basically to: 1) replace the roof with composition shingles;or 2) replace the roof with fire-treated wood shingles; or 3) replace the roof with some other acceptable material which would balance cost, appearance and durability considerations. The Uniform Building Code and Chapter 8-14 of the State Historic Building Code allow the use of alternative building materials for historic buildings where the alternative materials are comparable in safety or performance to conventional building materials. Treated, fire-retardant wood shingles have been shown to provide long-term fire resistance and are indistinguishable from untreated wood shingles. According to the City's Chief Building Official,new tests have concluded that the fire-resistive chemicals applied to the wood shingles stay.with the shingles for their lifetime. For aesthetic reasons and to be faithful in historical preservation efforts, staff feels that the fire-retardant wood shingles are the superior choice for these important historical resources. ALTERNATIVES 1. Approve the proposed re-roofing project with composition shingles as proposed. 2. Continue review of the project. Direction should be given to the applicant regarding desired information or needed revisions to plans. 1 -117 ARC 113-97 Page 4 RECOMMENDATION Approve the seismic retrofit and re-roofing with the condition that new roofing materials be fire- retardant wood shingles, or other material that the ARC deems appropriate, rather than the proposed composition shingles, based on the following findings: " 1. The choice of fire-retardant wood shingles will result in buildings that appear to be faithfully restored to their historical context consistent with the City's architectural guidelines and general plan policies regarding historical preservation. 2. Fire-retardant wood shingles further promote the original architectural style and character of the three buildings slated for re-roofing.

Jeff, At the request of the County Historical Society I am submitting the attached drawings for review by the Cultural Heritage Committee(CHC)and the Architectural Review Commission (ARC). The project for which this application is made includes strengthening of the roof framing, partial seismic retrofit and replacement of the roofing material of the Dallidet Adobe and the replacement of the roofing material on the Ramona Depot and the rest rooms all on the property at 1185 Pacific Street. This project has been instigated by the poor condition of the roofing on these three buildings and the fact that they have been leaking. During my investigation of the adobe, I found that the roof framing, which is a combination of original and replacement members, is in very poor condition. The rafters have sagged and appear to be contributing to the outward list of the walls. In addition, the Historical Society proposes to take the opportunity of having the roof open to install roof-to-wall ties and diaphragm improvements since the adobe is an unreinforced masonry building. The only elements of this project that will be visible after construction is the proposed change of roofing material from the existing wood shingles to composition shingles.The most recent roofing materials on these buildings is wood shingles and we are aware of no historical record that shows that it ever was anything else. Asphalt shingles were available in the 1890's' but the adobe dates from 1858 and the depot from 1889 and therefore it's most likely that they both originally had wood shingles. There are several reasons for this change of material. First of all, composition shingles are expected to be able to keep out the sun and rain for a longer period of time than wood shingles. The existing wood shingles have been in place for about 30 years and are well past their useful live. The Historical Society has chosen a heavyweight, laminated replacement shingle that is warranted for 30 years. There is also an obvious fire protection reason for the change. Wood shingles can be treated for fire resistance but the chemicals currently used are reported to loose their effectiveness after a few years where as composition shingles do not. ' Sweetser, Sarah M., °Roofing for Historic Buildings', Preservation Briefs#4, U.S. Department of the Interior, National Park Service, Preservation Assistance Division, Technical Preservation Services, 1978, pg. 3. 1 Mr.Jeff Hook August 12, 1997 pg.2. Not the least of all, there is a cost consideration for the change in material. Wood shingles would add almost 80%to the cost of the re-roofing, about$6000 on the adobe alone. When the initial savings, the additional life expectancy and the fire protection qualities are all considered, the potential cost savings to the Historical Society could be substantial; money that could be used for other restoration and stabilization projects at the building. While its clear that composition shingles will constitute a change to the historic fabric of the building, the Historical Society seriously considered the options and believes that this proposal would be the best for the building.We investigated alternate materials such as concrete tile that are made to look like wood shakes but none of them were found to match the scale and appearance of the existing roof as well as composition shingles. The Secretary on the Interior's Standards for Rehabilitation addresses this situation: `...the treatment of`rehabilitation'assumes that at least some repair or alteration of the historic building will be needed in order to provide an efficient contemporary use."(pg. 7). `Some exterior and interior alterations to the historic building are generally needed to assure its continued use, but it is most important that such alterations do not radically change, obscure, or destroy character-defining spaces, materials, features, or finishes."(pg. 10). 'New additions and adjacent or related new construction shall be undertaken 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.'(pg. 6). Based on this,we believe that the proposed change is needed and appropriate for these buildings.

On motion of Bob Schrage, seconded by Paula Carr, on a 6-0 vote, the minutes were approved with a correction to the spelling of "Shanghai Low" on page 5. (Matt Wittlesey arrived immediately after this item.) PUBLIC HEARING ITEMS 1. Request to nominate property located at 1408 Johnson Avenue to the Contributing List of Historical Properties, and to clarify City policies regarding the location of contributing historic properties outside of historic districts;Evelyn Talmage, applicant. Glen Matteson introduced the item. Committee members, Evelyn Talmage (owner), Brian Stan: (architect), and staff discussed the history of the house and its modifications, the relationship among the buildings on the parcel, the background of the Historic (H) zone boundaries, and the policies and precedents for designating Contributing or Master List properties inside and outside H zones. Factors identified in support of a Contributing designation included the age of the buildings and the apparently minimal exterior changes from their originally constructed appearance, and the association of the main house with a prominent citizen of the county. CHC Minutes, August 25, 1997 Page 2 On motion of Loren Nicholson, seconded by Paula Carr, with a vote of seven to none, the entire property was nominated as a contributing property. The Committee took no action on the question of extending the H zone to include the property, or on a general interpretation for contributing properties outside H zones. Committee members were divided on whether this case should serve as a precedent. All Committee members agreed the it would be desirable to have more clear guidelines for listing contributing properties, in relation to H zones. 2. Proposed architectural change to a Master List property located at 670 Islay Street, known as the historic Willett Home; Randy and Shayne LaVack, applicants. Glen Matteson introduced the item. Committee members, Randy LaVack (owner), and Bob Vessely (engineer) discussed the structural aspects of the chimney, past modifications to the house, the extent to which the chimney was a defining feature, and the presence or absence of chimneys on other houses in the area. On motion of Steve McMasters, seconded by Bob Schrage, with a vote of four to three, the chimney was determined to be a character-defining element, and the part of the chimney visible above the roof should be maintained or reconstructed. 3. Proposed architectural changes for Master List properties located at 1185 Pacific Street,known as the historic Dallidet Adobe and the historic Ramona Hotel Depot; San Luis Obispo County Historical Society, applicant. Glen Matteson introduced the item. Committee members, several Historical Society members, and Bob Vessely (engineer) discussed the choice of roofing material, considering appearance, fire safety, cost, durability, and structural considerations. On motion of Paula Carr, seconded by Loren Nicholson, with a vote of seven to none, the Committee recommended that the Architectural Review Commission approve the seismic retrofit and find that the wood-shingle roof is a "character-defining feature" of the adobe and the depot, and further that the Architectural Review Commission work with the applicant to identify which material is most acceptable for maintaining the adobe's and the depot's historic integrity and appearance. Committee members expressed a preference for wood shingle replacement for historic integrity, but acknowledged that the action left open the possibility of another material being approved by the Architectural Review Commission. /-Z3 CHC Minutes, August 25, 1997 Page 3 DISCUSSION ITEMS 4. Proposed agenda for the CHC retreattfocus session to be held on Monday, September 22, 1997,from 3:30 to 5:30 pm. John Mandeville explained the purpose for the retreat, and its intended format. Alice Loh suggested that considerations in having a historic preservation element of the General Plan be discussed, and that the CHC receive an update on the Railroad District Master Plan. It was decided that the CHC chair could contact the chairs of other advisory committees concerning communications and recommendations. INFORMATION SHARING Alice Loh noted upcoming Chinatown Public Art dedication and announced a fund-raising raffle to be held at Farmer's Market on Thursday, September 11. She also made available a flyer for a conference in Oakland on successful historic protection. She offered to work with other CHC members on guidelines for the Chinatown historic district. Bob Pavlik reported on a meeting where the results of the "certified local government" grant applications were announced, and the results confirmed that the benefits probably would not justify the effort to apply. S. Items for the September 22, 1997 CHC agenda. Potential items are an introduction of the Railroad District Master Plan,the subcommittee report on post-disaster recovery, and the update of the historic preservation guidelines. The meeting adjourned at 8 p.m. to the CHC retreat/focus session at 3:30 p.m. on Monday, September 22, 1997, followed by the regular meeting of the Cultural Heritage Committee in the Council Hearing Room (Room 9), at San Luis Obispo City Hall.

The Dallidet Adobe was built for Monsieur Pierre Hyppolite Dallidet in the mid-1850's, shortly after he arrived in San Luis Obispo from France. Dallidet planted a vineyard for a winery on his property surrounding the adobe. He married Senorita Ascension Salazar who was born in San Luis Obispo in 1840. They had seven children and it is said that in order to accomodate the large family, wooden quarters were added to the original structure. In 1889, the vineyard became the site of the Ramona Hotel railway depdt> 'The Dallidet family lived in the adobe for over one hundred years. Currently owned and operated by the County Historical Society, '2':t became a State Historical Landmark (Number 72'0) in 1960. PCul Dallidet, the youngest of Pierre's children, deeded his family home to the Society in 1953.
