I am sure you will find the information as interesting as we did. 1 have also included a disk with images of the building both before and after our renovation. I have tried to provide images that show the same angle of view in both cases. Please note that while Dacra is very excited about the potential designation of the building as an official historic site, we were equally enticed by the offer of some additional benefits for doing so. Namely a potential 10-year tax credit, and the possibility of receiving a transfer of development rights elsewhere in the district. am not sure if these potential benefits are part of your participation in this designation. However, since this is the first official package of information we have sent out regarding this matter, we thought it appropriate to clarify our interest in those benefits, in addition to the acknowledgement of our efforts in this wonderful building's renovation. Should you have any other questions, please feel free to reach me at (305) 531-8700.

Jtatment of Significance The Old Buena Vista Post Office and the Moore Fumiture Building are significant to the historical, architectural and cultural development of the City of Miami. These two buildings were built during the Land Boom era of the 1920s to provide business amenities that served as an impetus for future ommercial and residential development in the Buena Vista area. Renowned developer, D.P. Davis and prominent local pineapple plantation owner, l'heodore Vivian (T.V.) Moore were the two like-minded individuals who took the initiative to build these building that soon marked the commercial core of the Buena Vista area known as Commercial Biltmore subdivision. The Old Buena Vista Post Office and the Moore Furniture Building reflect the prosperity -nd frenetic pace of successful real estate development during the Florida real estate boom. These buildings are also noteworthy for their scale and iaterials of construction, which distinguished them from their surroundings and made them architectural innovations of the time.

Due to the outstanding architectural and historic significance of the buildings, we believe they should be granted the distinction and protection of historic designation. We have scheduled a preliminary review of the properties before the Historic and Environmental Preservation Board during its June 15, 2004 meeting. The public hearing will be held at 3:00 pm at City Hall (3500 Pan American Drive); we invite you to attend. At this meeting, the Board will evaluate the significance of the properties and determine whether the buildings appear to meet the criteria for historic designation. Should the Board decide to proceed with designation of the district, a separate hearing will be scheduled for this purpose. Once a building is designated by the Board, all exterior changes to the property will be subject to review. Smaller changes may be reviewed administratively by City Staff, while more complex changes will need to seek the approval of the Board. There will be no review of interior alterations, as long as they do not impact the exterior appearance of the building. I have enclosed a list of common questions regarding designation, as well as our brochures, explaining the City's Historic Preservation Program and profiling each of the City's historic properties. As of the date of this letter, no permits may be issued for work on this property until the Historic and Environmental Preservation Board acts, either to designate the property or to deny designation, or until 120 days have elapsed, whichever occurs first. If you have upcoming projects that may be disrupted by this restriction, please contact our office to discuss how best to proceed.

Thompson City Clerk - — — — IMO QUESTIONS AND ANSWERS ABOUT PROPOSECBubmitted Into the public HISTORIC DESIGNATIONS record in connection with item P2-i 3 on /i-ipjay Priscilla A. Thompson What is the City of Miami's Historic Preservation Ordinance? City Clerk The ordinance is a mechanism to recognize Miami's historic properties that meet the criteria for local historic significance. Its purpose is to encourage the preservation of historic properties by providing assistance and incentives to owners and to prevent unreasonable destruction or defacement of historic structures whenever an economically acceptable altemative can be found. That does the designation of a historic property mean to the property owner? Designation means that any future physical change to the exterior of a property must be approved in advance by the City. The review process is designed to assist owners in developing appropriate plans and designs, inform them of available benefits, and protect against unnecessary destruction of important historic features. How does a property become a historic site or historic district? First, a designation report, which fully describes the structure(s) and the associated historic and architectural significance, is prepared. Then, a public hearing is conducted where property owners and any interested citizens are encouraged to express their opinions. The Historic and Environmental Preservation Board then approves or denies the historic designation. Why would a property owner want his/her property designated as historic? The Historic and Environmental Preservation Board and its staff provide technical advice and assistance concerning appropriate design, construction methods, etc. Historic designation often carries a certain prestige that may improve marketability, increase property values, and secure financing that would not otherwise be available for an older building. What kinds of changes to a building would require approval and how long would it take? Ordinary maintenance and repair of existing features would not require approval, nor would alterations to the interiors of most properties. However, a building permit is required for all work in excess of $500. A special permit, called a Certificate of Appropriateness, would be required for most types of exterior remodeling, additions, new construction, and demolition. Minor changes such as repainting, or replacement of a roof or windows could be approved immediately upon submission of an application to the Department of Planning and Zoning, if those changes comply with the standards and guidelines for historic appropriateness. The ordinance permits a maximum of ten days for such approvals. Other changes such as additions, new construction, or demolition, would require review and approval by the Historic and Environmental Preservation Board, which meets once per INNEN Min Min Min month. The ordinance allows no more than 60 days for action on an application to the Board. What are the standards and guidelines on which Certificate of Appropriateness are based? The guidelines are a set of ten standards developed by the U.S. Secretary of the Interior to guide the preservation of buildings. Called the "Standards for Rehabilitation," they read as follows: 1. A property shall be used for its historic purpose or be placed in a new use that requires minimal change to the defining characteristics of the building and its site and environment. 2. The historic character of a property shall be retained and preserved. The removal of historic materials or alteration of features and spaces 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 architectural elements from other buildings, shall not be undertaken. 4. Most properties change over time; those changes that have acquired historic significance in their own right shall be retained and preserved. 5. Distinctive features, finishes, and construction techniques or examples of craftsmanship that characterize a property shall be preserved. 6. Deteriorated historic features shall be repaired rather than replaced. Where the severity of deterioration requires replacement of a distinctive feature, the new feature shall match the old in design, color, texture, and other visual qualities and, where possible, materials. Replacement of missing features shall be substantiated by documentary, physical, or pictorial evidence. 7. Chemical or physical treatments, such as sandblasting, that cause damage to historic materials shall not be used. The surface leaning of structures, if appropriate, shall be undertaken using the gentlest means possible. 8. Significant archeological resources affected by a project shall be protected and preserved. If such resources must be disturbed, mitigation measures shall be undertaken. 9. New additions, exterior alterations, or related new construction shall not destroy historic materials that characterize the property. The new work shall be differentiated from the old and shall be compatible with the massing, size, scale, and architectural features to protect the historic integrity of the property and its environment. 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. Submitted Into the public record in connection with item Pt-/3 on r14,-o4 Priscilla A. Thompson City Clerk What If the Historic and Environmental Preservation Board wanted an owner to do something he could not afford? The Board does not have authority to require anything that would create an unreasonable or undue economic hardship for an owner. If the owner can show such hardship, the Board would approve the most equitable solution, balancing economics with concern for the historic integrity of the property. Are the design standards and guidelines concerning a property retroactive? No. A property is designated as is, including features that are not in compliance with the new standards. It is much the same as a grandfather clause: everything can remain as long as it was permitted and can be maintained. Would an owner be forced to restore his property if it is designated? No. The Historic and Environmental Preservation Board only reviews changes proposed by _ the owner of the property. The Board could require an owner to modify plans he or she has proposed to meet standards and guidelines. But an owner who is not proposing any changes could not be required to make any. What effect would district designation have on my property taxes? None, as nearly as we can tell. Historic designation and assessed value are independent of _ each other. However, it is possible that the value of your property would increase because a historic building is often considered a desirable place in which to live or work. Are there any restrictions on buying or selling a designated historic property? No. An owner can sell to whom he or she pleases, as far as the Historic Preservation Ordinance is concerned. Isn't the Historic Preservation Ordinance a taking of private property rights? No. Property rights are always limited by regulations that protect the public health, safety, and welfare (i.e. zoning, building codes, fire codes, etc.). This ordinance is a set of regulations intended to protect the public welfare. Its legal precedent has been well _ established and tested in Miami and in over 800 U.S. cities that have similar historic ordinances in effect. The ordinance contains innumerable safeguards for private property owners, most notably the prohibition against creating an unreasonable or undue economic hardship. An illegal infringement on private property rights could occur only if the Historic and Environmental Preservation Board were to try and impose an unreasonable requirement contrary to the rules of the ordinance. Owners are protected against that possibility through appeals to the City Commission and the Circuit Court. Where can I get more information about the proposed historic designation? Additional information can be obtained from the City of Miami Department of Planning and Zoning, 444 S.W. 2"d Avenue, Third Floor, Phone 305-416-1433. The mailing address is P.O.

As I have mentioned in the past, Dacra was extremely honored that the City of Miami came to us with the request to designate this building. Coupled with the accolades from the architecture and design communities, it was a further commendation of the restoration to the building that was completed under our ownership. However, due to the confusion in some of the correspondence, we did not understand that the designation would also include a portion of the interior leaseable space within the building. For that reason, I formally request that in the resubmission of the Buena Vista Post Office/Moore Furniture Building historical designation, all language referring to the designation of the interior atrium be removed from the report. As always, we are happy to discuss any questions or concerns you may have, and would like to reiterate our full support for the designation of the exterior of the Moore Building.

Dacra worked closely with the Historic and Environmental Preservation office at the City during this process, and we were honored to have this designation bestowed upon this great Miami building. However due to some communication errors, we were not aware that the historic designation included a portion of the interior of the building. Throughout this process, we were under the impression that only the exterior of the building was being designated and for that reason we supported the efforts. Therefore, we formally request to appeal the designation language that was approved by the HEP Board, thereby eliminating the designation of the interior atrium. Our appeal is only to that language that refers to the interior atrium, not to the designation of the exterior. Enclosed with this letter is check number #23923 in the amount of $500.00 for the appeal fee. Should you have any questions, please contact me at (305) 531-8700.

The Standards for Rehabilitation (codified in 36 CFR 67 for use in the Federal Historic Preservation Tax Incentives program) address the most prevalent treatment. "Rehabilitation" is defined as "the process of returning a property to a state of utility, through repair or alteration, which makes possible an efficient contemporary use while preserving those portions and features of the property which are significant to its historic, architectural, and cultural values." Initially developed by the Secretary of the Interior to determine the appropriateness of proposed project work on registered properties within the Historic Preservation Fund grant-in-aid program, the Standards for Rehabilitation have been widely used over the years --particularly to determine if a rehabilitation qualifies as a Certified Rehabilitation for Federal tax purposes. In addition, the Standards have guided Federal agencies in carrying out their historic preservation responsibilities for properties in Federal ownership or control; and State and local officials in reviewing both Federal and nonfederal rehabilitation proposals. They have also been adopted by historic district and planning commissions across the country. The intent of the Standards is to assist the long-term preservation of a property's significance through the preservation of historic materials and features. The Standards pertain to historic buildings of all materials, construction types, sizes, and occupancy and encompass the exterior and interior of the buildings. They also encompass related landscape features and the building's site and environment, as well as attached, adjacent, or related new construction. To be certified for Federal tax purposes, a rehabilitation project must be determined by the Secretary to be consistent with the historic character of the structure(s), and where applicable, the district in which it is located. As stated in the definition, the treatment "rehabilitation" assumes that at least some repair or alteration of the historic building will be needed in order to c wo a.

For example, certain treatments --if improperly applied --may cause or accelerate physical deterioration of the historic building. This can include using improper repointing or exterior masonry cleaning techniques, or introducing insulation that damages historic fabric. In almost all of these situations, use of these materials and treatments will result in a project that does not meet the Standards. Similarly, exterior additions that duplicate the form, material, and detailing of the structure to the extent that they compromise the historic character of the structure will fail to meet the Standards. The Secretary of the Interior's Standards for Rehabilitation The Standards (Department of Interior regulations, 36 CFR 67) pertain to historic buildings of all materials, construction types, sizes, and occupancy and encompass the exterior and the interior, related landscape features and the building's site and environment as well as attached, adjacent, or related new construction. The Standards are to be applied to specific rehabilitation projects in a reasonable manner, taking into consideration economic and technical feasibility. 1.

Page 1 of 5 Those approaches, treatments, and techniques that are consistent with the Secretary of the Interior's Standards for Rehabilitation are listed under the "Recommended" section in each topic area Guidelines for Rehabilitating Historic Buildings Introduction to the Guidelines The Guidelines for Rehabilitating Historic Buildings were initially developed in 1977 to help property owners, developers, and Federal managers apply the Secretary of the Interior's Standards for Rehabilitation during the project planning stage by providing general design and technical recommendations. Unlike the Standards, the Guidelines are not codified as program requirements. Together with the Standards for Rehabilitation they provide a model process for owners, developers, and Federal agency managers to follow. The Guidelines are intended to assist in applying the Standards to projects generally; consequently, they are not meant to give case -specific advice or address exceptions or rare instances. For example, they cannot tell owners or developers which features of their own historic building are important in defining the historic character and must be preserved --although examples are provided in each section --or which features could be altered, if necessary, for the new use. This kind of careful case -by -case decision -making is best accomplished by seeking assistance from qualified historic preservation professionals in the planning stage of the project. Such professionals include architects, architectural historians, historians, archeologists, and others who are skilled in the preservation, rehabilitation, and restoration of the historic properties. The Guidelines pertain to historic buildings of all sizes, materials, occupancy, and construction types; and apply to interior and exterior work as well as new exterior additions. Those approaches, treatments, and techniques that are consistent with the Secretary of the Interior's "Standards for Rehabilitation" are listed in bold -face type under the "Recommended" section in each topic area; those approaches, treatments, and techniques which could adversely affect a building's historic character are listed in the "Not Recommended" section in each topic area. To provide clear and consistent guidance for owners, developers, and Federal agency managers to follow, the "Recommended" courses of action in each section are listed in order of historic preservation concerns so that a rehabilitation project may be successfully planned and completed --one that, first, assures the preservation of a building's important or "character -defining" architectural materials and features and, second, makes possible an efficient contemporary use. Rehabilitation guidance in each section begins with protection and maintenance, that work which should be maximized in every project to enhance overall preservation goals. Next, where some deterioration is present, repair of the building's historic materials and features is recommended. Finally, when deterioration is so extensive that repair is not off, EU o �tce)-5Ca O Q • o Q C .N co 2 2 http://www2.cr.nps.gov/tps/tax/rhb/guide.htm 11/5/2004 The Secretary of the Interior's Standards for Rehabilitation & Illustrated Guidelines for R... Page 2 of 5 possible, the most problematic area of work is considered: replacement of historic materials and features with new materials. To further guide the owner and developer in planning a successful rehabilitation project, those complex design issues dealing with new use requirements such as alterations and additions are highlighted at the end of each section to underscore the need for particular sensitivity in these areas. How to Use The Guidelines Identify, Retain, and Preserve The guidance that is basic to the treatment of all historic buildings --identifying, retaining, and preserving the form and detailing of thos architectural materials and features that are important in defining the historic character --is always listed first in the "Recommended" area. The parallel "Not Recommended" area lists the types of actions that are most apt to cause the diminution or even loss of the buildings's historic character. It should be remembered, however, that such loss of character is just as often caused by the cumulative effect of a series of actions that would seem to be minor interventions. Thus, the guidance in all of the "Not Recommended" areas must be viewed in that larger context, e.g., for the total impact on a historic building. Protect and Maintain After identifying those materials and features that are important and must be retained in the process of rehabilitation work, then protecting and maintaining them are addressed. Protection generally involves the least degree of intervention and is preparatory to other work. For example, protection includes the maintenance of historic material through treatments such as rust removal, caulking, limited paint removal, and re -application of protective coating; the cyclical cleaning of roof gutter systems; or installation of fencing, protective plywood, alarm systems and other temporary protective The parallel "Not measures. Although a historic building will usually require more extensive Recommended" work, an overall evaluation of its physical condition should always begin at this area lists the level. types of actions that are most apt to cause the diminution or even loss of the Repair buildings's Next, when the physical condition of character -defining materials and features historic warrants additional work repairing is recommended. Guidance for the repair of character. historic materials such as masonry, wood, and architectural metals again begins with the least degree of intervention possible such as patching, piecing - in, splicing, consolidating, or otherwise reinforcing or upgrading them according to recognized preservation methods. Repairing also includes the limited replacement in kind --or with compatible substitute material --of extensively deteriorated or missing parts of features when there are surviving prototypes (for example, brackets, dentils, steps, plaster, or portions of slate or tile roofing). Although using the same kind of material is always the preferred option, substitute material is acceptable if the form and design as well as the substitute material itself convey the visual appearance of the remaining parts http://www2.cr.nps.gov/tps/tax/rhb/guide.htm 11/5/2004 The Secretary of the Interior's Standards for Rehabilitation & Illustrated Guidelines for R... Page 3 of 5 of the feature and finish. Replace Following repair in the hierarchy, guidance is provided for replacing an entire character -defining feature with new material because the level of deterioration or damage of materials precludes repair (for example, an exterior cornice; an interior staircase; or a complete porch or storefront). if the essential form and detailing are still evident so that the physical evidence can be used to re-establish the feature as an integral part of the rehabilitation project, then its replacement is appropriate. Like the guidance for repair, the preferred option is always replacement of the entire feature in kind, that is, with the same material. Because this approach may not always be technically or economically feasible, provisions are made to consider the use of a compatible substitute material. GATE MIMES AND FASTS. Se, switE Bath Ways, awl Btlfi4l rtliag It should be noted that, while the National Park Service guidelines recommend the replacement of an entire character -defining feature under certain well- defined circumstances, they never recommend removal and replacement with new material of a feature that --although damaged or deteriorated --could reasonably be repaired and thus preserved. Design for Missing Historic Features When an entire interior or exterior feature is missing (for example, an entrance, or cast iron facade; or a principal staircase), it no longer plays a role in physically defining the historic character of the building unless it can be accurately recovered in form and detailing through the process of carefully documenting the historical appearance. Where an important architectural feature is missing, its recovery is always recommended in the guidelines as the first or preferred, course of action. Thus, if adequate historical, pictorial, and physical documentation exists so that the feature may be GATE FASTENINGS accurately reproduced, and if it is desirable to re- establish the feature as part of the building's historical appearance, then designing and constructing a new feature based on such information is appropriate. However, a second acceptable option for the replacement feature is a new design that is compatible with the remaining character -defining features of the historic building. The new design should always take into account the size, scale, and material of the historic building itself and, most importantly, should be clearly differentiated so that a false historical appearance is not created.

Page 4 of 5 Alterations/Additions to Historic Buildings Some exterior and interior alterations to 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. Alterations may include providing additional parking space on an existing historic building site; cutting new entrances or windows on secondary elevations; inserting an additional floor; installing an entirely new mechanical system; or creating an atrium or light well. Alteration may also include the selective removal of buildings or other features of the environment or building site that are intrusive and therefore detract from the overall historic character. The construction of an exterior addition to a historic building may seem to be essential for the new use, but it is emphasized in the guidelines that such new additions should be avoided, if possible, and considered only after it is determined that those needs cannot be met by altering secondary, i.e., non character -defining interior spaces. lf, after a thorough evaluation of interior solutions, an exterior addition is still judged to be the only viable alterative, it should be designed and constructed to be clearly differentiated from the historic building and so that the character -defining features are not radically changed, obscured, damaged, or destroyed. Additions to historic buildings are referenced within specific sections of the guidelines such as Site, Roof, Structural Systems, etc., but are also considered in more detail in a separate section, New Additions to Historic Buildings. Energy Efficiency/Accessibility Considerations/Health and Safety Considerations These sections of the rehabilitation guidance address work done to meet accessibility requirements and health and safety code requirements; or retrofitting measures to conserve energy. Although this work is quite often an important aspect of rehabilitation projects, it is usually not a part of the overall process of protecting or repairing character -defining features; rather, such work is assessed for its potential negative impact on the building's historic character. For this reason, particular care must be taken not to radically change, obscure, damage, or destroy character -defining materials or features in the process of rehabilitation work to meet code and energy requirements.

Page 1 of 8 An interior floor plan, the arrangement and sequence of spaces, and built-in features and applied finishes are individually and collectively important in defining the historic character of the building. Their identification, retention, protection, and repair should be given prime consideration in every rehabilitation project. In evaluating historic interiors prior to rehabilitation, it should be kept in mind that interiors are comprised of a series of primary and secondary spaces. This is applicable to all buildings, from courthouses to cathedrals, to cottages and office buildings. Primary spaces, including Historic shopping arcade following entrance halls, parlors, or living rooms, successful rehabilitation. assembly rooms and lobbies, are defined not only by their features and finishes, but by the size and proportion of the rooms themselves --purposely created to be the visual attraction or functioning "core" of the building. Care should be taken to retain the essential proportions of primary interior spaces and not to damage, obscure, or destroy distinctive features and finishes. Secondary spaces include areas and rooms that "service" the primary spaces and may include kitchens, bathrooms, mail rooms, utility spaces, secondary hallways, firestairs and office cubicles in a commercial or office space. Extensive changes can often be made in these less important areas without having a detrimental effect on the overall historic character.
