It also forwards Compatibility Review Standards for Replacement Houses, Standards for Historic Designation, and Standards for Alteration of Historic Landmark Residences. These are additional regulations authorized by the Interim Ordinance, to be adopted by Council Resolution. These additional regulations will be utilized until modified or until they are permanently replaced with an updated Historic Protection Ordinance and Historic Resource Inventory. RECOMMENDATIONS: Staff recommends that the Council, after conducting a public hearing: 1.Adopt the Ordinance establishing Interim Regulations. 2.Adopt the Resolution containing Compatibility Review Standards, Standards for Historic Designation, and Standards for Alteration of Historic Landmark Residences. CMR:451:96 Page 1 of 8 BACKGROUND Background information related to these Interim Regulations has been previously described in the attached reports dated September 30, 1996 (CMR:417:96) and October 15, 1996 (CMR:436:96). On September 30, 1996, the City Council provided policy direction to staff regarding the content of interim regulations. On October 15, 1996, staff forwarded the Ordinance for first reading and forwarded the preliminary Compatibility Review Standards and preliminary Standards for Historic Designation for review. The purpose of this report is to forward the Ordinance for second reading and to forward the historic preservation regulations, including Compatibility Review Standards, Standards for Historic Designation, and Standards for Alteration of Historic Landmark Residences for public hearing and adoption. POLICY IMPLICATIONS A policy framework for guiding the Interim Regulations was presented in CMR:417:96, and the Council provided policy direction to staff for incorporation into the Ordinance and Standards. A question related to Section 16.50.020 (d), the definition of demolition, has been raised since the October 15, 1996 Council adoption. The definition includes the language: "or any portion of a street-facing facade." This language implies a more stringent protection of the street facing building wall than was intended by staff. If Council intends for staff to use other than our traditional "demolition definition," which allows removal of nearly all building elements except the studs in the walls, they should so direct. It was not staff’s intent to require all portions of the facade to be protected, including windows, exterior materials, etc. Staff can administer either interpretation, but prefers to continue the traditional interpretation. It allows greater flexibility to the home remodeler. DISCUSSION Since the first reading of the Ordinance and the public review on October 15, 1996, the Historic Resources Board, public and Council have raised several issues, which have prompted staff to make adjustments in the Ordinance and Standards. Those modifications are outlined below and highlighted in the documents. It is worth noting that, prior to publication, the Compatibility Review Standards will be further enhanced with instructional text and illustrations, after the regulatory elements are adopted by Council. These embellishments are to make the Standards "user friendly" and to provide further administrative and background information, including illustrations and a checklist for applicants and staff. Space in the document has been retained for this purpose with notations in several instances. CMR:451:96 Page 2 of 8 Definition of Demolition The Historic Resources Board expressed concern, in the minutes of their October 14, 1996 meeting, regarding the definition of demolition and how it might inadvertently create difficulties for applicants who are trying to restore and reconstruct an historic structure. Staff had already discovered such instances and agrees with the HRB. A modified definition of demolition has been added to address the concern. (Refer to Sections 16.50.020 (d) and (g), Ordinance, Attachment A.) Standards for Historic Designation The Historic Resources Board, in the minutes of October 14, 1996, expressed a concern that the Standards of Historic Designation did not adequately address historic and cultural criteria when designating Contributing Properties and did not sufficiently include "sites" and "places" of merit. Staff agrees that the modifications recommended by the HRB are more in keeping with current National and State definitions and has, therefore, added the wording highlighted in Exhibit B. It is worth clarifying, however, that the modified definition is not an amendment to the existing Historic Preservation Ordinance, applying citywide. It will be applied only to "protected residences" as defined in Section 16.50.020 (j) through these interim regulations. Application of any updated definition throughout the community will take place only when the permanent regulations are adopted by Council and the Historic Inventory isupdated. Compatibility Review Standards - Council Questions At the meeting of October 15, 1996, Council Member Rosenbaum raised several questions regarding the draft Compatibility Review Standards. These are addressed as follows: Is there a potential conflict between the requirements for certain roofing materials (page 24 of the Compatibility Standards) and the Fire Department Codes and requirements or State Law? Staff contacted the Acting Fire Marshal to confirm that the materials listed in the Compatibility Standards are acceptable to the Fire Department and meet Fire Codes. He confirmed that these materials are all acceptable. The City of Palo Alto does not have an ordinance preventing the use of wood shakes, as some communities have adopted. The City, however, through the Site and Design review process, does require fire retardant roofing materials in the "high" wildland fire risk area west of Interstate 280. There are no pre-1940 residential structures in the "high" fire risk area. The Health and Safety Code, Section 13132.7(a)(1), requires that both wood shake and wood shingle must be minimum "Class C" fire resistive. This requirement will be imposed at the time of issuing a roofing permit, as is currently the case with any reroofing or new roof permit. CMR:451:96 Page 3 of 8 !s there a potential conflict between the Title 24 energy conservation requirements and the requirement for using certain types of windows (page 20, of the Compatibility Standards)? Staff contacted the Chief Building Official to review the requirements for acceptable window treatments. According to the Chief Building Official, the Title 24 standards can be achieved in a variety of ways, generally through a combined approach of any of the following: wall and roof insulation classifications, number and size of openings, and the use of single, double or triple pane window treatments. Title 24 does not require double pane windows, and the Compatibility Standards do not prevent the use of double pane window treatments, so there is no conflict between the two. The Compatibility. Standards allow for double pane windows. When using divided light type windows, the standards do not allow the type which place the "dividers" inside the two panes of glass. With this type of window, the imitation muntins produce no relief or shadow line. If divided lights are selected, they are required to be tree divided lights, which include single panes with muntins; or alternatively, if double pane windows are used, the type which places the imitation muntin on the outside of the double panes of glass is required. With this second type, the imitation muntin produces a shadow line. It is, therefore, a higher quality imitation than the type which places the "divider" inside the glass. Is there a problem with the requirement for a 12-foot double garage door opening and necessary clearance for automobiles to enter and park inside? The requirement for 12-foot garage door width was an error in the first draft of the Compatibility Review Standards. The error has been corrected in the current Exhibit A, page 12, to require a 16-foot garage door, and the pavement widths related to this measurement have been likewise widened. Compatibility Review Standards - Revisions The following refinements have been made to the Compatibility Review Standards since Council last reviewed them on October 15, 1996. The Introduction and the first two sections of the document, How to Use the Compatibility Review Standards, and Adding On or Remodeling a Pre-1940 House, were in outline form in the previous draft, and these sections have been developed to a more complete form in Exhibit A. Changes that relate to regulatory requirements have been highlighted in the text of the attached Compatibility Review Standards. Changes resulted from public input, additional field observation, or research which has occurred since the October 15, 1996 document was reviewed. The changes can be characterized as three types: 1) those made for clarification and consistency, 2) those made to allow more flexibility in prescriptive dimensions and CMR:451:96 Page 4 of 8 locations, and 3) an additional design requirement for both garage doors and wall material application practices. The modified sections are summarized below. Front Setbacks 1. Wording was changed to clarig~ that all of the house must be located at or behind the prevailing setback line. Garages 1. The requirement that garages located in the rear setback be at least 6 feet from the rear property line was deleted. A restriction on balconies over attached garages on comer lots was deleted. 3.The maximum width of garage doors was changed from 12 feet to 16 feet. Design standards were added for garage doors to minimize the appearance of width and increase architectural compatibilit3~ with the neighborhood. The special allowance requiring only one on-site parking space for lots with width less than 40 feet or area less than 4,000 square feet was changed to apply to all substandard lots, to be consistent with the zoning definition of substandard lots. A requirement was added that attached garages on these lots be recessed at least two feet behind the main front facade of the house. Driveways 1. The location at which a driveway may begin to widen from 9 feet to the width of the garage door(s) was increased from 18 feet to 27 feet from the front of the garage. o The requirement to provide a wall, fence or hedge to screen wide expanses of paving was changed to apply in all situations, not just for comer lots. The width of paving that triggers this requirement was increased from over 14 feet to over 18 feet. o The minimum width of space required to allow for planting between a driveway and the property line and the driveway and a building wall was reduced from 2 feet to 1.5 feet. This requirement was extended to apply to driveways adjacent to rear property lines as well as to side property lines. An exception was added to eliminate the required separation between the driveway and the building wall along the back half of the house. CMR:451:96 Page 5 of 8 Public 1. Right of Way Wording was changed to clarify, that the restriction on driveways to no closer than 10 feet from a street tree does not apply to existing driveways, but rather to relocating, realigning or widening driveways. Wording was added to clarify that the restriction on 5.5 linear feet of paving in the planting strip does not include the driveway apron. Landscaping 1. The requirement for the protection of oak trees was changed to include wording from the tree ordinance regarding protection only of trees located within the required setbacks. Compatibility with Neighborhood Architectural Style 1. Wording and examples about using characteristics of a traditional architectural style in a consistent manner, rather than combining architectural styles, was moved from requirements to recommended practice. Windows 1.The requirement to "reuse and match" original window materials was changed to "reuse or match." o The restriction on the use of nonrectangular or decorative windows on garage doors was relocated to the garage section. An exception to clear glass was made for frosted glass and glass block in bathrooms or for privacy along property lines. Entry_ Features 1. Wording was added to clarify that where the focal point on the front of the house is a primary window rather than the entry, the primary window must be in a main living area. Roofline i. Using high quality roof materials, where roofs are highlighted as a prominent design feature, was moved from requirements to recommended practices. Walls 1. and Finishes Wording was added to clarify what types of stucco finishes are compatible with existing architectural and neighborhood character. CMR:451:96 Page 6 of 8 o A requirement was added regarding changing wall materials only at certain locations on the wall in order to avoid the appearance of a false, "stuck on" appearance. National Standards for Rehabilitation and Guidelines for Rehabilitating Historic Buildings The attached resolution references the National Standards for Rehabilitation and Guidelines for Rehabilitating Historic Buildings as the standards for evaluating modifications to historic landmarks. This is consistent with Council policy direction on September 30, 1996. ALTERNATIVES Any number of alternatives are available to the Council, and a range of policy options was presented in the earlier CMR:417:96, dated September 30, 1996. Staff recommends that a four month status report on the Interim Regulations be returned to Council for evaluation. At that time, it may be necessa~ to modify the Administrative Regulations and/or examine some other alternatives or reexamine alternatives that were not previously selected. FISCAL IMPACT The cost of administering the Interim Regulations is discussed in the City Manager’s Report of October 28, 1996 (CMR:446:96) and was discussed in the previous CMR:436:96. ENVIRONMENTAL. ASSESSMENT Because the interim regulations have been directed to strengthen the City’s Historic Protection Ordinance, preventing demolition of historically significant structures for protection of the environment, the ordinance is categorically exempt from CEQA under a Class 8 Exemption. ,STEPS FOLLOWING APPROVAL Staff will return to Council at the earliest possible time with a budget and scope of services for completing both the Historic Protection Ordinance and Historic Inventory simultaneously and on a faster time line than anticipated in the budget adoption.

Thirty-four of these houses were constructed before 1940 and located mostly in the city’s older, more traditional neighborhoods. Concerned that the loss of so many older houses would erode the distinctive character of these neighborhoods, the City Council adopted Interim Regulations to limit or restrict demolition of houses that have historic significance, either as Landmarks or as Contributors to the historic character of the neighborhood, and to assure that in cases where these houses are demolished the houses that replace them will contribute the same qualiu of design and compatibility with neighborhood characteristics as the original houses. These provisions help to assure current and future residents that the character of their neighborhood will not undergo radical change, and to protect the investments that residents have made in their houses and neighborhoods. When do the Compatibility Review Standards Apply The Compatibility Review Standards apply to new construction that replaces a house that was built before 1940 and has been determined to have historic significance as a Contributor building. In addition, the Standards apply to extensive remodels of Contributor buildings when 50% or more of the exterior walls are being removed. In rare instances where a Landmark building is permitted to be removed or demolished, the replacement structure also would have to comply with these Standards. See Section I. for more details about how to determine whether the Compatibility Review Standards apply to your project. SECTION I:HOW TO USE THESE COMPATIBILITY REVIEW STANDARDS Consider the option of an addition or remodel of your house rather than demolition and replacement. An addition or remodel of your older house that is sensitive to its original characteristics will help to preserve the distinctive historic architectural qualities of Palo Alto. Before you decide to demolish and replace your house, consider whether an addition or remodel will meet your household’s needs. Read Section II.., which discusses in more detail the opportunities and benefits of a successful addition or remodel. As you complete the Compatibility Worksheet in Section III., consider the special characteristics of your house and how it contributes to the special character of the neighborhood. If you decide to retain at least 50% of the walls of your house, including the front facade, you are not required to comply with the Compatibility Review Standards. Instead, use the information provided in the Compatibility Review Standards and the Compatibility Worksheet exercise to help you identify the essential characteristics of your house and neighborhood and to design your addition or remodel in a way that will celebrate and enhance the style of your house and the special qualities of the neighborhood. o Determine whether the Compatibility Review Standards are mandatory for your project. When do the Compatibility Review Standards apply? Your project must comply with the Requirements of the Compatibility Review Standards if both of the following apply: The original house that is being replaced or extensively remodeled was constructed before 1940 and has been determined to be an Historic Landmark Residence or a Contributing Residence The proposed construction plans will result in removal of 50°./o or more of the exterior walls or the street facing facade of the original house. How do I know if my house is an Historic Landmark or Contributor building? First, verify that your house was constructed prior to 1940. Consult the Assessor’s data, available on microfiche in the Planning Department, which will show the date of construction for your house. Next, consult the Ci~r of Palo Alto’s current Historic Inventory, and find out whether it has been identified in the Inventory as a structure with historic architectural or cultural significance. Structures identified as Category 1 or 2 are considered to be Historic Landmark Residences, but structures identified as Category 3 or 4 will require an Historic Merit Evaluation to assess their level of historic significance. Because the Inventory has not yet been updated to assure that all structures with historic, architectural or cultural merit are identified, the house may still have historic merit even if it is not identified in the Inventory. If your house is not on the Inventory, you must request a Historic Merit Screening by Planning staff to determine whether the house could possibly be considered to be a Contributing or Historic Landmark Residence. If based on the Historic Merit Screening, it appears your post-1940 house could not meet the Standards for Historic Designation, then you are not required to follow the requirements which apply to demolition, alteration and replacement of Contributing Residences. If it appears, based upon the Historic Merit Screening, that your house may meet the Standards for Historic Designation, a Historic Merit Evaluation will be required. This evaluation will include a recommendation by the Historic Resources Board to the Planning 4 Director regarding the determination that a pre-1940 house is either a Historic Landmark Residence or Contributing Residence. If the house is determined to be a Historic Landmark Residence, no application for demolition will be approved during the current interim regulations, except under special circumstances. Any remodel or additions will need to be approved by the Historic Resources Board according to National Standards and Guidelines. If your house is determined to be a Contributing Residence, you must comply with the Compatibiti~, Review Standards and obtain approval for a replacement structure prior to demolition of the contributing residence. Demolition is defined as removal of more than fifty, percent of the perimeter walls, or removal of the street- facing facade. Demolition does not include removal and replacement in kind of deteriorated, non-repairable materials required for the restoration or rehabilitation of the structure and resulting in no change to its exterior appearance or historic character. Process to apply for approval of an extensive remodel or for demolition and replacement. Outline the steps in the review process. Submittal requirements: Photo montage of the block, both sides of the street, and photographs showing all sides of the original house and architectural details. Completed Worksheet assessing character of the neighborhood and showing how the replacement house meets the requirements of the Compatibility. Review Standards. (The Worksheet in the back of the SFR Design Guidelines will be modified~ see Attachment.) New construction plans showing all existing and proposed development and all existing trees on the entire lot, the location of adjacent structures, and the location of all existing curbs, curb cuts, paving, and other infrastructure including street trees located in the Public Right of Way. 4.Aerial photo How to use the Requirements and Recommendations in the Compatibility Review Standards Difference between Requirements and Recommended Practices. Exceptions: An exception process will be made available that allows the applicant to seek relief from the requirements of the Compatibility Review Standards when site conditions cause unusual circumstances that make application of such Standards an unreasonable burden. The process will involve a hearing opportunity and a decision by the Director or his designee. Based on findings that the proposed alternative better achieves design quality and compatibility with the existing neighborhood than would the strict application of the requirements of the Compatibili~ Standards, the proposed alternative may be approved. SECTION II.REMODELING A PRE-1940 HOME Remodeling or adding on to an existing house may be the best alternative for households who need more space or have changing requirements. Increasing the size of a home presents both opportunities and problems. There may be an opportunity, to improve the layout of the entire house and to enhance compatibility with the neighborhood. By retaining elements of the original homes and continuing its architectural character in additions, remodeled homes can preserve Palo Alto’s precious architectural heritage and the charm and desirability of older neighborhoods. The first step in planning an addition is to study the Zoning Ordinance regulations to determine what may be built. Be aware that you can apply for a Home Improvement Exception (HIE) if you find that you cannot adhere to the strict provisions of the zoning ordinance for site development regulations such as setbacks, daylight planes, height, lot coverage and incidental amounts of floor area. Home Improvement Exceptions apply to projects where 75% of exterior walls and 25% of existing roof area is maintained, and are intended to help sustain the integrity of the existing house design concept or neighborhood character. If you are remodeling a Historic Landmark Residence or Contributing Residence, you may also be eligible to use the Historic Building Code. This code provides added flexibility in meeting the intent of the code where strict interpretation of the Uniform Building Code could adversely affect the preservation of historic buildings. Next step, review these recommendations and requirements, recognizing that if you retain iiaore than 50% of exterior walls including the front facade, the requirements are not mandatory, in either case, following the recommendations will help you assure that your remodeled home preserves its original architectural character and enhances your neighborhood character. You may also wish to consult an architect to help you with the planning and design process. Use the worksheet in Section VI and the reference materials in Sections V to identify distinguishing characteristics of the neighborhood and patterns which contribute to the streetscape. Refer to the Guide to Palo Alto Architectural Styles and the reference materials in Section V to identify the original architectural style of your house. As you design your addition, look for ways to continue the architectural character and features of the original home in the remodeled portion. Be sure that if you are adding at the ground floor or second story that the overall building massing is consistent with the houses architectural character. Be sure to continue streetscape patterns that help define neig,hborhood character as well. SECTION III:RECOMMENDED PRACTICES & REQUIREMENTS FOR DESIGNING A COMPATIBLE REPLACEMENT HOME The purpose of the Compatibility Review Standards is to guide construction of a new residential structure or a substantial alteration to a pre-1940 residential structure in a way that preserves the special and desirable qualities of the neighborhood. These special qualities come from characteristic patterns of building placement, open space, landscaping and architectural detail. These patterns are similar throughout Palo Alto’s pre-1940 neighborhoods, even though the styles of architecture may be varied. It is the repetition of these qualities in hundreds of houses, each one different yet conforming to the essential pattern, that gives these neighborhoods their strong character of cohesion and visual richness. The essential characteristics of these neighborhoods can be identified in the following five points. The main focus of each house is on the design of the front facade, particularly the entry, and its connection to the front garden and to the street. The houses are located in a "garden" setting, with planting, open space and views between buildings. Garages and car parking are located at the back of the site. The architecture shows careful attention to scale, balance, proportion, detail, materials and craftsmanship. Regularly spaced street trees and planted parking strips line the streets. (Provide photo illustrating these points) This Section is divided into two parts. Streetscape and Open Space includes those elements that determine the view from the street and the arrangement of buildings and open spaces. Architectural Character includes those elements that comprise the design of the individual structures. Each of the characteristic elements is organized in the following way: i.A discussion of how this element contributes to the special character of the pre- 1940 neighborhood 2.An outline of "Recommended Practices" that will help to preserve and enhance that character. o A list of the "Requirements" that each project will have to meet in order to be approved. STREETSCAPE AND OPEN SPACE The front yard, sidewalk, street trees, fences, driveways, landscaping, everything in front of the house, all contribute to our experience as we walk or drive down the street. This combination of elements constitutes the streetscape. The streetscape of older Palo Alto neighborhoods is characterized by a high .degree of architectural variety and pedestrian detail, unified by certain characteristic patterns of landscaping and building placement. Front Setbacks Discussion. The front setback is the distance from the front of the house to the front property, line (not the sidewalk). The minimum set by the zoning regulations is 20 feet. However, in historic neighborhoods with a different setback pattern a smaller or larger setback pattern may prevail, and should be respected by new construction. Recommended Practice." Maintain the existing setback pattern by building to the prevailing setback line. Notice that comer houses may be located closer to the street than other houses on the block. 10 Requirements: Locate at least 50% of the front facade of the house at the prevailing setback line, with the remainder of the front facade at or behind that line. The prevailing setback line is the line closest to the street with 75% of the houses located behind it. If the house is on a corner and the original house is located closer to the street than the prevailing setback line, then the required setback is the setback of the original house. o If the front facade of the original house is being preserved, the setback of the original house may alternatively be the allowed setback. Garages Discussion: In most situations, garages in pre-1940 neighborhoods are separate from the house and located at the back of the lot. This pattern continues the outbuilding relationship to the main house that carriage houses had in a previous era. It has a powerful impact on the character of these neighborhoods in at least five ways: 1) the amount of paving in the front yard is the minimum required for access; 2) the most prominent design element on the facade of the house is the entry or a major window rather than the garage; 3) side driveways provide open space and separation between houses; 4) cars can be parked in the driveway while still being out of the front yard; 5) the difference in size between houses and garages establishes a pattern of variety in building volumes, rather than mostly large, uniformly sized buildings. Recommended Practices: 1.Locate the garage to minimize its visibility. Design the garage so that it is architecturally compatible with the house but does not compete with the house as the primary focus. 11 Requirements: Locate the garage at the rear of the site and detached from the house by at least 12feet. If located at least 75feet from the front property line, zoning allows the garage to be located adjacent to the side and rear property line. Alternatively, an attached garage can be located no closer than 60 feet from the front property line, provided that a side setback of at least 6feet is maintained. Locate the side wall of the garage no more than l O feet closer to the side property line than the side wall of the front part of the house, thus partially screening view of the driveway and garage from the street. (This will be illustrated with a diagram.) No part of the second story can extend over the garage within 10feet of the garage side wall. The garage must have a separate roof that is the same pitch as the house roof, or less. In this case, second floor balconies are not permitted over the garage to protect the privacy of the adjacent property. If the house is located on a corner, the garage may be placed in the rear yard setback and accessed from the side street. The garage must be located at least 16feet from the street side property line Alternatively, garages on corner lots may be attached if located outside rear y ,"ar"t setback. No, ;;;c,r~ ~" -" 1 ca ....... __:,:.._ :~ _., ....,~o~ ~,~_~ ~.. _,, ~:~’~",’ s’ "" ~e ~-o~"~,,,~’~e garage must be recessed at least 2feet behind ¢~e side wall .fete In a single car garage, use a garage door that is 8feet wide, or less. In a double car garage, use two doors not more than 8feet wide separated by a vertical support at least 8 inches wide, or use one door not over at-2 16feet wide. Where three car garages are permitted by ordinance, use one door eight feet wide and one door at-2 16feet wide, or less. Design garage doors with square or vertically proportioned elements to minimize the apparent width of the doors. If the door 12 is more titan eight feet wide, design the door so that it has the appearance of being divided vertically into two distinct sections. Do not use Rancher style doors, because the strong horizontal proportions emphasize the width of the door. Do not use steel garage doors. Do not use nonrectangular or decorative windows on garages or garage doors. (Photo illustration) If the garages on the two adjacent properties and the garage for the original house are on the same sides of their respective houses, then locate the driveway for the new house in this same way so that the pattern of open space between houses is preserved. If alleyway access is provided, required parking shah be accessed from the alley and the garage shah be located within 5feet of the rear property line. 7. substandard lots, and where no alley access is available, only one on-site parking space is required and a single car attached garage is allowed. The front of the garage must be recessed at least two feet behind the main front facade of the house. If two parking spaces are provided, one must be tandem. Carports are not permitted, unless they are located where the open sides cannot be seen from a public street. Driveways Discussion." Driveways at nearly all ofPalo Alto’s pre-1940 houses are between 6.5 and ¯ 10 feet wide, with 9 feet being the most common width. They are typically located several feet from the side property line and several feet from adjacent building walls; usually this space is planted with a hedge or other landscaping. Surface materials are treated in one of two ways. The most common treatment is asimple, unobtrusive surface of asphalt or poured cement. In other cases the driveway is surfaced with bricks, cobbles, 13 stones, rubble or gavel, and adds textural interest and an element of craftsmanship to the front garden. Recommended Practice." Minimize the width of driveways and the amount of paving on the site. "Holls~vood" strips with planting between the wheel tracks may be used instead of solid paving. Use simple, traditional paving materials, and provide planting that will help to flame the site and screen the paving. Requirements: Make driveways 9feet wide or less. Driveway curb cuts must have a vertical curb and be no more than lOfeet wide with a 3foot radius. Within 4-8 27feet of the garage doors, driveways may widen to no more than the width of the garage door(s) plus 2feet. However, no driveway may be more than 12feet wide within 5feet of the public sidewalk. Interior sidewalks, patios, etc. may adjoin the driveway for no more than 6 linear feet. ¯,,,o ,,~-,-~,~,,.t o ,--, o,,.~ stT~ets,e driveway widens to more than q-418 feet at any location, inside the property line that is visible from a public street, provide a wall, fence or hedge along the property line to screen the paving. Locate driveways at least =2 1.5feet from the side or rear property line and at least =2 1.5feet from a;;y L..:,.,: .......,,¯ ,,.,,,,,o,~ ,,.,,,, the side of the house to provide space for planting on both sides of the driveway, except that no planting space is required between the driveway and the back half,f the house. (An illustration or diagram will be provided) Use the following materials for driveway surfaces: asphalt; poured cement with a troweled or exposed aggregate finish; real brick, cobbles, or stone ; rubble; or gravel For driveways, do not use precast interlocking pavers or stamped concrete, ~ :-’~ since these materials generally lack the appearance of craftsmanship associated with traditional materials. 14 Public Right of Way: Discussion: Street trees are one of the most striking features ofPalo Alto’s older neighborhoods. Trees provide shade and canopy and help define the street and sidewalk areas. They also provide a unifying element to the streetscape ofolder neighborhoods, while the variety, of tree species used provide a range of shade, color and other characteristics. Recommended Practice." 1.Note the location, spacing and type of street trees on the street and take this into consideration in the design of the new house, locations of garage and driveway and the design of landscaping and paving in the front yard and planting strip. Requirements: 1.Do not relocate, realign or widen a driveway to within l O feet of any existing street tree, unless it is not possible to access the site and still meet this requirement. 2.If street trees are missing along the property frontage on the street, locate the driveway to allow replacement of the missing trees at approximately 25feet intervals. 3.Limit paving or hard surfaces within the parking strip to no more than 5.5 linear feet per street frontage, not including the driveway apron. 4.Provide irrigated planting of ground cover or small shrubs in the parking strip. 5.If there is a fence or wall along the property line, provide irrigated planting in the space between the sidewalk and the fence or wall. 15 Landscaping Trees provide shade and canopy and provide an asset to both the individual property owner and the neighborhood. Mature trees and other large plant material are a part of the special quality of older neighborhoods. Recommended practice." Locate and identify all mature trees and shrubs on the property. Observe their characteristics and what benefits they may be providing in terms of shade, seasonal color, etc. and consider that some may be old species no longer generally available in the trade and therefore rare. Retain and protect mature vegetation where possible. o Consistent with neighborhood patterns, fence materials and design should be compatible with the house style and neighborhood character. Solid fences and fences over four feet tall should be avoided, except to provide backyard privacy. Locate perimeter fences or walls behind the property, line to allow planting to soften the appearance of the fence. o Design the landscape to be compatible with the house design and neighborhood. Be aware that irrigated front lawns are the main source of water for many street trees, so if drought tolerant landscaping is used, consider providing irrigation to the street trees. If irrigation to the front yard is being turned off during construction, use soaker hoses to water street trees during the interim. If there is an uninterrupted sweep of lawn across several properties, maintain this pattern. Requirements: All valley oak and live oak trees over 11.5 inches in diameter or 36 inches in circumference measured 4.5feet above natural grade that are located in required setbacks are protected under the City’s street tree ordinance and must be retained. 16 Prior to demolition and during construction, provide protective fencing and frequent deep watering to all plant materials that are being retained, including street trees. ARCHITECTURAL CHARACTER Palo Alto’s older neighborhoods are characterized by a combination of architectural styles, with certain styles predominant in each neighborhood. Each of these historic house styles is composed of a coherent and consistent combination of materials, window treatments, building massing, ornamentation and roof treatment. While individual details may vary, these characteristics provide a sense of unit,:, within each house and with others of the same style. Additions and remodels of pre-1940 residences should be compatible with the style of the original structure. A first step in designing a remodel or addition, therefore, is identifying the architectural style of the original building. Common Architectural Styles in Palo Alto Houses The list below includes the predominant architectural styles of Palo Alto homes built before 1940. Illustrations and descriptions of character-defining elements of these styles can be found in Section V. These houses represent the history of this area, dating from the founding of the town of Mayfield and Palo Alto through the start of World War II. While there are some other architectural styles represented in pre-1940 buildings, these represent the most common styles. Victorian Queen Anne Colonial Revival Shingle Style Spanish Colonial Revival Craftsman Bungalow Tudor Revival Streamline Moderne 17 Some of the predominant styles are particularly well adapted to the area’s climate and building materials, such as the Craftsman, Shingle and Spanish Colonial Revival styles. Prominent California architects such as Julia Morgan and Birge Clark have designed buildings in these styles which are an important part of Palo Alto’s architectural heritage. For further information on Palo Alto and Bay Area architectural traditions, consult the following references and the Guide to Palo Alto Architectural Styles in Section V: Historic and Architectural Resources of the Cit~, of Palo Alto, Rehab Right: How to Utilize the Full Value of Your Old House. and Single Family Residential Design Guidelines. Compatibility., with Neighborhood Architectural Style Discussion." Each of Palo Alto’s older neighborhoods gets its distinctive character from a blend of architectural styles. Some neighborhoods and some blocks are more eclectic and others are more homogeneous. Often there is a predominant style, such as the shingle style or bungalow style, which gives the neighborhood a sense of unity and distinctiveness. Recommended Practice." New residential construction should be compatible with the architectural character of the neighborhood,,,,,~--’ ~’~,,, ,~ ~,,l,~ ~: ~’:-^*:-’~ ~ Each house should be desired wi~ ~ ~derst~d~g of the ch~actefistic elements of~e p~icul~ s~le selected for ~e ho~e ~d wi~ c~e~l a~ention to scale, bal~ce, propo~on, detail ~d cra~m~Np. When using characteristics of a traditional architectural style, use these characteristics in a consistent manner; rather than combining 18 characteristics of more than one st.vle in a single structure. For example, Mediterranean!Spanish style stucco houses should not employ neocolonial details such as shutters or steep roofs. (This paragraph was moved from requirements to recommended practices.) Requirement: Plans which use traditional architectural features are required to identify a style from the references: Section V Common Palo Alto Architectural S&ies, Historic and Architectural Resources of the ~ of Palo Alto, Rehab R~ht. or Single-Family Des~n Guidelines,. Only those architectural characteristics included in the description of a particular style in the above references may be included in a single structure. Alternatively, if an applicant can provide a local example of a pre-1940 residence with the same combination of original architectural characteristics in a single structure they may utilize that combination ofcharacteristics in their own plans. Windows Discussion." Windows contribute a great deal to the character of the house. An addition that uses windows that are significantly different from those used in the original house will severely disrupt the character of the house. For instance, using sliding aluminum windows in a house that has wood double hung windows would detract from the house. Certain distinctive window shapes, such as round, arched, pointed, fan- shaped or diamond-shaped windows, need to be used sparingly so that they complement the architectural style and do not overwhelm the proportions of the facade. Extremely tall windows can also disrupt the scale of the house. Most older residential styles did not use non-rectangular and oversized windows at all; or used them only for emphasizing the major living area or an entry. Each architectural style is characterized by specific window proportions, materials, mullion detailing, trim and placement. Refer to the description of 19 common architectural styles and examples of original houses for models of appropriate window treatment. Requirements: Where the architectural style of the original house is being retained, reuse and or match original window materials. Maintain proportions, detailing and materials of original windows. No more than one non-rectangular or "special" window may be used per street facade. No windows on street facades can be taller than the top of the first floor of the building. Where non- rectangular windows are used, they must be compatible with the architectural character of the house and neighborhood. This limitation does not apply to windows located on the front door. (Restrictions on special windows in garage doors were moved to the garage section.) Windows must be wood, wood with vinyl or metal cladding, or steel Vinyl or aluminum windows will be all, wed for bathrooms and basements but must have the same or similar finish to other windows. Windows must have clear glass, except that glass block or frosted glass may be used in bathrooms or for privacy along property lines. Windows with divided lights must be true divided lights, or double pane windows with full size (minimum 3/8" deep) muntins attached to the exterior of the glass. Recessed windows: In stucco walls, recess window pane a minimum of 2.5 inches behind the outside wall surface, not including trim around the windows, in order to enhance the impression of the massiveness of the walls. In other types of walls a minimum recess ofl.5 inches is required. Dormer windows may be used only where they open directly into habitable space. This does not preclude small, ~,, ~,~,~,,,,~,o,~, "eyebrow" type roof vents, where compatible with the architectural style. 2O Entr3.’Features Discussion." Entw features in Palo Alto’s older neighborhoods include front porches, alcoves, loggias, terraces, and covered or uncovered stoops. Front porches can be viewed as covered entry features which are open on two or more sides. These front porches and entries often provide a seating area as well as an entryway, and become an important scene for neighborly interaction while providing visual interest to the passerby. They also provide a transition in scale between the house and the outdoors at the pedestrian scale. In some cases, a large window in a primary living area is the focus on the front facade, rather than the building entrance. The materials, proportions and location of front porches, entries and primary windows should be compatible with the house style and neighborhood character. Requirements: If there is an established pattern of porches on the block, (50 % of houses on the block face or on both sides of the street combined), then provide a front porch. 2.Ira porch is not incorporated, include an entry feature or principal window (larger than other windows) in a main living area on the front of the house. m Design porches with a minimum dimension of at least 6feet in depth and an area of at least 60 square feet to provide both an entry area and usable seating area~ Entry feature openings and roof eaves cannot be higher than the top of the first floor of the building. 21 Building Massing Discussion: Building massing is a fundamental ingredient of architectural style and neighborhood character. While many houses in Palo Alto’s older neighborhoods are two story, they often contain a number of elements which serve to decrease the visual impact of the two story volume with a one story portion, roof or gable details, or entry features. These features provide a pedestrian scale. The taller building elements and trees help define the larger scale of the street. Together these elements produce the overall character and richness of the streetscape. Building massing is also a key concern of neighbors, where two story elements can affect sunlight access, views and privacy for adjacent properties. Recommended Practices." Employ one story elements such as porches, entry features, and arcades to create a transition in scale between the street and two story building elements. Consider neighbors needs for sunlight, privacy and views. Use setbacks or sloping roofs to reduce shadows and intrusions on neighbor’s windows and open spaces. Roofline o Building massing should be compatible with the house’s architectural style and neighborhood-character. For example, for Bungalow designs do not include two story elements unless they are set back at least ten feet from front and rear walls. (This was moved from requirements to recommended practices.) Discussion." Roof lines and the detailing ofr0of design and consmaction contributes to the character of Palo Alto’s older neighborhoods. Generally, the existing pattern is houses composed of simple shapes with simple roof forms. Some newer houses have introduced a profusion of roofs over individual building 22 elements, which clutter the facade. Roofs should not over-emphasize the garage or entryway to the detriment of the harmony of the overall facade. Roof forms found in Palo Alto vary from the shallow to moderate slopes of bungalow, shingle and Spanish houses to the steep forms of Tudor and Victorian houses. Compatibility with neighborhood patterns and the specific architectural styles ofthe house should be continued in new construction. Traditional roof materials in older Palo Alto neighborhoods depended upon the architectural style. Shingle style houses used wood shingles and shakes; Spanish style houses used genuine clay tile, or tar and gravel for flat roofs; Tudor and neocolonial houses sometimes used slate. Recommended Practices: Where roofs are specially highlighted as a prominent design feature, use authentic, high quality materials such as wood shake, wood shingle, clay tile or slate. (This was moved from requirements to recommended practices.) Requirements: Roofline, roof details and roof materials must be compatible with the architectural style of the house to produce an overall, unified architectural style. For traditional styles, the style must be identified and the roof features must be consistent with those described for that style in the following references: Historic and Architectural Resources of the Cir. of Palo Alto, Rehab Right, or Single-Family Design Guidelines,. Alternatively, if an applicant can provide a local example of a pre-1940 residence with the same combination of architectural style and roof characteristics they may utilize that combination of characteristics in their own plans. t The roofs over entry features must have the same roof pitch and detail as the rest of the house. Eaves on entry feature roofs must be located no higher than the top of the first floor of the building. 23 For roofs, use asphalt shingles, wood shingles, wood shakes, genuine clay tile, genuine slate, or tar and graveL Walls and Finishes Discussion: An important characteristic of older neighborhoods is the generally high level of quality and craftsmanship used in construction and finishing of wall surfaces. Often the variations in color or texture resulting from hand craftsmanship add to the appeal and interest of the finished wall. In addition, certain styles were marked by specific finishes, such as white, cream or other light colored paints on stucco for Spanish style houses, and unpainted redwood shingles and beams on Shingle Style houses. Requirements: Stucco must be applied by hand. Do not use spray-on finish materials or textured paints. Use a traditional stucco finish texture found on pre-1940 buildings in Palo Alto, such as Float, Spanish, Mission, Monterey, Californian or English. Do not use Lace or heavy textures. m Use real wood siding, not composite products, vinyl or aluminum siding. Change from one wall material to another only where there is a change in wall plane and at an interior corner, not at an exterior corner, since this gives the appearance that the material is only applied to the surface and not integral to the structure of the wall Where remodelling, use same materials and finishes as existing house, or if documentation exists showing that the house originally had a different finish, then that finish may be used. 24 SECTION IV.COMPLETING THE COMPATIBILITY WORKSHEET: IDENTIFYING NEIGHBORHOOD CHARACTER AND ARCHITECTURAL STYLE Completion of the Compatibility Worksheet in Section VI is required for your application for approval of a major remodel or construction of a new structure to replace a Contributing Residence. The worksheet should be completed at the very beginning of the design process, so that the information you assemble regarding the character of your neighborhood and your house can be used to guide your design decisions. There are several major steps in completing the worksheet: 1.Identify Neighborhood Character and Streetscape Patterns Identify the Architectural Character of Your Home and Other Homes in the Neighborhood Describe your proposed design for a remodel or replacement home in relationship to Neighborhood Character and Streetscape patterns Describe the Architectural Character of your proposed design in relationship to the Palo Alto architectural traditions and the original house. 1.Identify Neighborhood Character and Streetscape Patterns You may wish to photograph the streetscape, patterns of planting, and fencing, and anything which makes the neighborhood special and gives the neighborhood charm. Study all of the patterns which contribute to the richness of the neighborhood and choose those that are consistent with the character of your home. Identifying and defining each neighborhood by its own special character helps to define important design criteria for an individual project. Here are some broad characteristics to define and distinguish the neighborhood character and streetscape patterns in various districts in Palo Alto where most pre-1940 houses are located. 25 Crafts Example: Professorville, Community Center and Old Palo Alto Most of the homes were built prior to the 1940s. Streets lined with mature trees which provide unifying feature. Landscape strips with street trees between sidewalk and street. Lots generally narrow with houses consistently set back on the lot Predominant architectural style bungalow and craftsman style Front porches are common, fences are low and houses are visible from street Garages generally detached and located in the rear of the lot with a narrow driveway to the street, minimizing views of parking areas and pavement. Mixed -Examples: College Terrace, Ventura, Old South Palo Alto, Downtown North -Mixed or eclectic neighborhoods are the least uniform in Palo Alto. -Amount of landscaping varies as does type and placement of street trees. -Mixed in density and architectural style. On some blocks, there is no uniform pattern with respect to number of stories, lot size or garage location. Nonetheless, there can exist elements of building appearance, size, placement on a lot and/or landscaping, which help unify diverse character and scale. Estates -Examples: Crescent Park, some parts of Old Palo Alto -Lots are very wide and large, with substantial houses set back 40 feet or more from the street, with large side setbacks. -Trees and lush landscaping dominate the streetscape. -Planter strips add to the rich greenery along the street. -Predominant house styles include Tudor, Colonial Revival and Mediterranean. Houses are two and three stories and garages are detached in the rear. Rural Example: Barron Park The character of rural neighborhoods is dominated by trees and foliage. There are many trees, but no uniform street tree type. The rural character is emphasized by the lack of curbs and sidewalks. - Streets are rambling and narrow. The architecture is varied, but most houses are small, one story and set back from the street. 26 Identify the Architectural Character of Your Home and Other Homes in the Neighborhood Architectural character is derived from the harmonious combination of a number of character defining elements. These elements include materials and finishes, roof slope, ornamentation, massing, and window design and placement. Most pre-1940 houses are built in a distinctive architectura! style, which combines these elements in a characteristic pattern.

The current designation Categories 1, 2, 3 and 4 would be replace by two categories-- Landmark and Contributor. The current designation criteria would be replaced by the new Criteria for Evaluming the Significance of Historical Resources. Criteria for Evaluating..the Significance of Historical Resources A property would be deemed to be historically significant of it is found to be of significance to Palo Alto, the Bay Area, the State of California or the nation under one or more of the following criteria. Historic property may include buildings, structures, objects, landscape elements or natural features, e.g., E1 Palo Alto. It is associated with events or patterns of events that have made a significant contribution to the broad patterns of local or regional histo~’ and cultural heritage of California or the United States. o It is associated with the lives of architects, builders, other persons or historical events that are important to Palo Alto, the Bay Area, the nation or to California’s past. It is an example of a type of building or is connected with a business or use which was once common, but is now rare, It embodies the distinctive characteristics of a type, period, region, or method of construction, is particularly representative of an architectural style or way of life important to the city, region, state or nation, represents the work of a master, possesses high artistic values or contains elements demonstrating outstanding attention to architectural design, detail, materials or craftsmanship. It has yielded, or has the potential to yield, information important to the prehistory or history of Palo Alto, the Bay Area, the state or nation. Designated historic property will be categorized as a Landmark or Contributor according to the following definitions. Landmark Properties:. Landmark properties are exceptional or major buildings, groups of buildings, structures, objects, landscape elements or natural features which are of preeminent national, state, Draft Standards for Historic Designation Page 1 regional or local importance, exhibit meritorious work of the best architects, are an outstanding example of the stylistic development of architecture or landscape architecture in the United States, California, the Bay Area or Palo Alto, or are identified with historic people or with important events or activities in the city, region, state or nation. The Landmark may have some exterior modifications, but the original character is retained. Contributing Properties: Contributing properties are buildings, groups of buildings, structures, objects or sites that relate to and support the historic character of a neighborhood grouping or district because of historical or cultural importance or in scale, materials, proportions, setting or other factors. A contributing property may have had extensive or permanent changes made to the original design, such as inappropriate additions, extensive removal of architectural details or changes to exterior materials. Draft Standards for Historic Designation Page 2 Attachment C Minutes of the 8:00 a.m., October 14, 1996 Meeting of the Historic Resources Board- at the Squire House Present:Monty Anderson Dennis Backlund Marty Bernstein Roger Kohler Mildred Mario Carol Murden Caroline Willis The Meeting was called to order by the Chair, Mildred Mario. Item #1 - Discussion of the City Managers Report #11 Pertaining to 453 Melville, 1531 College and 275 Lowell being exempt from the Urgency and Interim Moratorium. We believe replacement structures on these sites will be subject to the Compatibility Standards and request clarification from Staff. Board Member Backlund voiced his concern that Contributing Buildings still have very little protection except that demolition will now be delayed until the replacement structure review process is completed. Board Member Murden is dissatisfied with the Landmark Residence Appeal Process because the HRB cannot appeal. Board Member Willis stated that she believes the definitions are weak and should include cultural criteria for designation. They seem to be too focused on neighborhoods instead of individual structures and the fees are inappropriate. She also believes that the Compatibility Guidelines are geared only to certain neighborhoods rather than to the city as a whole. Board Member Kohler thinks that Compatibility Standards should apply to a neighborhood that has historic structures even if the demolition is of a pre- 1940 house that is not designated as historic. Board Member Anderson believes that the neighborhoods should determine what controls are imposed in their specific area. We should get permanent regulations as soon as possible. The HRB has been pushing for an ordinance revision for years and this is an indication of what happens when you wait until it becomes an urgent problem that must be dealt with immediately. The entire Board discussed historic buildings and Compatibility Standards. Two issues are becoming confused - saving historic houses which should be the HRB’s chief concern, and the issue of the changing scale and character of Palo Alto neighborhoods which is not an HRB purview, unless an historic neighborhood is involved. The Board believes that neighborhood associations should participate, in conjunction with Staff, in decisions regarding the preservation of neighborhood character. Board Member Anderson believes that the interim ordinance will be a deterrent to people buying historic houses. The interim ordinance will be filled with flaws that are associated with hastily prepared regulations. Board Member Mario agreed that this is a possibility and that we need to work on incentives. Board Member Bernstein is concerned with the fees for the small home owner. We should have incentives. How does the staff determine the age of the house, etc. It should be very simple to determine whether the house they have is impacted by the ordinance. If you are restoring the building and are forced to rebuild and replace the facade, in kind, for structural reasons it should not come under the demolition definition. Item #2 - Recommendations Board Member Willis moved seconded by Board Member Bernstein to introduce a new definition of restoration and reconstruction which would be exempt from the definition of demolition. This requires documentation of the existing structure and reconstruction as documented. Motion was approved 6 ayes one (Monty Anderson) absent. Board Member Willis moved seconded by Board Member Murden to encourage the Council to adopt attachment C - Draft Standards for Historic Designation - but with modification of the definition of Contributing Properties to add historic and cultural criteria; and to change the term Contributing Properties to Structures and Sites of Merit. Motion was approved 5 ayes two absent (Roger Kohler and Monty Anderson). Board Member Bernstein moved that Compatibility Review Standards should not define construction means but only define the artistic effect, otherwise it may become cost prohibitive. Motion failed for lack of a second. Board Member Willis moved seconded by Board Member Mario to endorse the 6 staff recommendations under Discussion on pages 3 through 5 of the City Managers Report #11. Motion was approve 4 ayes 1 abstain (Marty Bernstein) two absent (Roger Kohler and Monty Anderson). Board Member Willis moved seconded by Board Member Bernstein to strongly encourage City Council to establish Incentives for Restoration and Preservation. We would like the Council to: 1. Initially consider waving fees for HIE’s and zoning variances per HRB recommendations. 2. Direct Staff to use the Historic Building Code where it would further preservation. 3. After a property is designated Historic, Staff should be directed to explore relief from inappropriate parking and set-back requirements or other inappropriate R-1 zoning restrictions. Motion was approved 5 ayes 2 absent (Monty Anderson and Roger Kohler). Item #3 - Commentary The Historic Resources Board had a discussion of the City Council’s postponement of re-designating the AME Zion Church from a Category 3 to a Category 1. Mildred Mario, Carol Murden, Caroline Willis and Dennis Backlund voiced their concern over Council’s refusal to re-designate the AME Zion for reasons other than the criteria for historic designation. Since the State and Federal Government both determined that it is worthy of inclusion on the National Register of Historic Places, and the State has placed it on the California Register of Historic Resources, we believe the Council has not allowed the Inventory to reflect the actual historic status of this building. Motion to adjourn by Caroline Willis seconded by Carol Murden unanimously approved. Minutes prepared by Mildred Mario TO: Attachment D City of Palo Alto City Manager’s Report HONORABLE CITY COUNCIL FROM:CITY MANAGER DEPARTMENT: Planning and Community Environment AGENDA DATE: September 30, 1996 CMR:417:96 SUBJECT: Policy Options and Potential Process Description for the Interim Regulations Related to Demolition of Residential Structures Constructed Prior to 1940 REQUEST: This report outlines some policy and process options for the City Council and requests direction on the content of the Interim Regulations that will replace the September 17, 1996 Moratorium Ordinance on demolition of older residences. RECOMMENDATIONS: Staff recommends that the Council: Direct staff to return with Interim Regulations after providing the following direction: Provide direction to staff regarding the definition of"demolition" that should be included in the Interim Regulations. bo Provide direction to staff regarding the circumstances under which demolition of pre-1940 residential structures will be permitted under the Interim Regulations. Co Provide direction to staff regarding the standards and decision-making body that should be used to evaluate historic significance of a structure during the Interim Regulation period. do Provide direction to staff regarding compatibility criteria to be used to evaluate replacement structures, if Council decides to include such a provision in the Interim Regulations. CMR: 417:96 Page 1 of 20 eo Provide a confirmation of the procedural structure for assessing and regulation demolitions of pre-1940 residential structures during the interim regulation period; Direct staff to return with a budget amendment ordinance to fund contract staff, both professional and support staff, to administer the interim regulations on a cost recovery basis, and/or to fund Design Compatibility Criteria, if these are desired; Based on the accelerated time line shown in Attachment A, direct staff to return to Council with an account of the costs of this assignment, both interim and permanent regulations, on the Planning Division Work Program and budget for 1996-97, and with a budget amendment ordinances. BACKGROUND The number of single-family demolition permits issue in 1996 reached 52 by mid-September of 1996, 24 of which were for residences built prior to 1940. On September 12, 1996, Council memb~ers Fazzino, Andersen, Kniss and Schneider forwarded a memo to colleagues identifying their alarm over the growing number of demolition permits for attractive older houses in Palo Alto. The memo acknowledged that, while Council had already directed preparation of a new Historic Preservation Ordinance, many residential structures are likely to be demolished during the time it will take to develop new regulations and update the historic building inventory. Without an evaluation of these structures prior to their demolition, valuable historic assets could be lost to the community. Finally, the memo raised concern that those who are rebuilding replacement housing are not sufficiently sensitive to the "special culture" of Palo Alto. The majority of new homes do not reflect the quality, pattern and character of Palo Alto’s traditional neighborhoods. On September 16 and 17, 1996, Council considered and adopted an Urgency Moratorium Ordinance, to last for a temporary period until November 15, 1996. On September 24, 1996, Council extended the Urgency Ordinance until November 30, 1996. The Moratorium allows time for Council to direct and staffto prepare interim regulations. The interim regulations are intended to be utilized during the period when staff will be updating the Historic Ordinance and Inventory.. (Refer to Attachment A for time line) Testimony was received from a number of builders, homeowners, real estate agents, and residents who would be affected by the regulations. As had been suggested in the Council Colleagues memo, Council directed staff to return with an assessment of those "pipeline" projects that had applied for building permits, or received planning entitlement prior to September 17, 1996. The intent was to allow exceptions from the Moratorium Ordinance for projects in the "application pipeline". Staff CMR: 417:96 Page 2 of 20 provided this analysis and ordinance language allowing Council to grant exceptions to the Urgency Ordinance on September 24, 1996. On September 17, 1996, the Council also directed staff to return on September 30, 1996 for policy direction as to the nature and content of the interim regulations. These interim regulations will serve to regulate demolition until the Historic Ordinance and Inventory can be updated. The purpose of this report is to provide an outline of policy options and to describe a potential process description for further Council direction. POLICY IMPLICATIONS There are significant policy issues raised in the memo and Council action directing the Urgency Ordinance and Interim Regulations. The current body of policy describing the public interest in protecting historic structures is contained in the Comprehensive Plan, Urban Design Element, and the Historic Preservation Ordinance. The City also has significant legal obligations under its 1992 agreement with the State of California to become a "certified" local government agency for historic preservation purposes. The bodies of -policy which establish the interests of the private property owner are contained in the Zoning Regulations; Single Family R-1 and Multiple Family RM Regulations; and in the ARB Ordinance for Multiple-family structures. The R-1 Guidelines contain policies which become critical when a single-family application requires an exception, variance, or ARB review. Otherwise, in general the Guidelines do not bind property owners. The challenge before the Council is great. Palo Alto is in the midst of an escalating single- family real estate market and construction boom. The Objective of the regulations is to describe, measure, and balance the public interest for retaining and preserving historic structures and historic neighborhood integrity during the time it takes to prepare permanent regulations, against the private interests of individuals and developers to sell, remodel or tear down and rebuild residences on their property over approximately the next year or until permanent regulations are adopted. While this is a difficult assignment even without deadline constraints, Interim Regulations have the advantage of being temporary. They will be in place only until the final regulations can be studied and adopted. There is precedent for this use of Interim Regulations in Palo Alto. The R-1 Urgency Moratorium and Interim Regulations in the mid-1980’s were used for well over a year prior to being discarded by the Council and replaced with the current floor area, daylight plane and dormer exception provisions in today’s R-1 regulations. The primary policy areas which Council has raised relate to 1) demolition of historic structures, 2) evaluation of historic structures not now on the inventory or reevaluation of structures now on the inventory but insufficiently classified, and 3) compatibility of CMR: 417:96 Page 3 of 20 replacement housing with the pattern, character, quality, and historic integiW of Palo Alto’s traditional neighborhoods. , DISCUSSION The following discussion provides both a policy-framework for making choices about what to include in the Interim Regulations, and a process outline for implementing the interim regulations. I. Policy Framework A. Demolition Policy It is the requirements and standards for alterations and demolitions that are at the core of historic resource protection ordinances nationwide. For purposes of this discussion, staff has divided historically meritorious structures into two categories: 1) Landmark structures; and 2) Contributing Structures. The current Palo Alto Historic Protection Ordinance classifies structures into Categories 1, 2, 3, and 4. In general, Categories 1 and 2 can be considered to have landmark status, while Categories 3 and 4 have contributing status. In this report, the term "landmark status" or "landmark structure" refers to properties in Categories 1 and 2 or properties with potential to be in Categories 1 or 2. "Contributing status" or "contributing structures" refers to properties in Categories 3 and 4, or those with potential to be classified as Category 3 or 4. 1. Demolition Policy, Pre-Moratorium Currently, the Historic Preservation Ordinance allows demolition of all significant landmarks and contributing historic structures, except Category 1 and 2 structures in the Downtown under certain circumstances. The current ordinance provides for a delay of up to one year of demolition for Category 1 and 2 structures in locations other than the Downtown, and for Category 3 and 4 structures within the Downtown. The Council has heard the HRB recommendation that this ordinance is outdated and insufficient for protecting the public interest in preserving historic structures. Council has directed that an ordinance update be undertaken in this fiscal year. CMR: 417:96 Page 4 of 20 2. Demolition Policy, Moratorium The Urgency Ordinance has temporarily removed the right to demolish any residential structure built prior to 1940, except those that were in the permit "pipeline" as defined by Council on September 24, 1996. This would include all structures on the existing Historic Inventory and others not now on the inventory. The intent of the Moratorium is to place all demolition approvals in abeyance until some interim regulations can be drafted which will serve to protect the public interest, balancing the property rights of the individual, while permanent regulations can be studied and developed. The interim regulations will presumably allow the City to evaluate the structure prior to demolition, to prevent demolition in certain instances, and to allow demolition in specified circumstances. 3. Demolition Policy Options, Interim Regulations Two demolition-related aspects of the interim regulations require direction from Council. Council needs to: a) confirm or amend the definition of "demolition" now contained in the Urgency Moratorium for use in the Interim Regulations; and b) decide under what conditions demolition of historically significant structures will be permitted. The Council Colleagues memo directed that the interim regulations should allow demolitions "when appropriate". It is assumed by staff that if the property is determined through the interim process to have no historic merit as either a landmark or a contributing structure, then demolition should be permitted. Other circumstances which might warrant approval of the demolition need to be developed by Council, and the method and findings for making this determination require direction. Historic preservation ordinances throughout the country provide a range of options for consideration. The most permissive (e.g., San Diego, Portland, Carmel) are like Palo Alto’s current ordinance. They allow demolition or alteration of nearly all historic structures, but delay demolition to allow the property owner and community to explore alternatives and incentives for preservation. Some also provide ordinance incentives for retaining historic structures. Other, less permissive ordinances (e.g., Atlanta, Oakland, Santa Barbara) prevent demolition or alteration of landmark structures, except under the most extreme public safety situations or in the event of a catastrophic event. The most restrictive ordinance staff reviewed does not allow demolition of landmark buildings under any circumstances, and requires the owner CMR: 417:96 Page 5 of 20 to rebuild the landmark to its former state if the structure is destroyed by a catastrophic event (Los Gatos). Most ordinances that staff reviewed allow contributing structures to be demolished and!or altered under certain circumstances. Many require assurances for design quality and compatibility for replacement structures. a. Demolition Definition The Moratorium Ordinance defines "demolition" as "removal of more than 50% of the perimeter walls of the structure." This definition is the one now used by staffto determine when an application is a "new residence" versus a "remodel". The Home Improvement Exception process is available only for additions and remodels, for example, and the 50% rule is used to determine if a project qualifies for an HIE. This definition is administered and enforced through review of the demolition plans associated with building permits. Council should also be aware that during remodeling, building staff often observe increases in the amount of demolition, based upon previously unknown conditions. As an administrative practice, the Chief Building Official prepared a notice that ~ additional demolition beyond that shown on approved plans will result in issuance of a stop work order. The 50% definition, however, is not consistent with that used in many historic preservation ordinances, and would allow far more of the structure to be removed than is customary for protecting the historic integrity of a significant building. In historic protection ordinances, demolition is usually defined much more strictly to include "an act or process that destroys or razes in whole or in part a building, structure, or site of historic merit. " The Council needs to decide what definition of"demolition" should be used in the interim regulations: Definition Option 1: Urgency Moratorium. Retain the 50% perimeter wall definition in the Definition Option 2: Adopt a stricter definition, more in keeping with typical historic preservation ordinances, which includes additions and modifications to the existing structure and encourages retention of a higher percentage of perimeter walls, up to 100% Staff recommends that Option 1 be utilized for all contributing structures, but that a stricter definition be employed for Landmark structures. CMR: 417:96 Page 6 of 20 Definition Recommendation 1: Staff recommends that Definition Option I be used for all structures in Category 3 or 4 and all structures not now on the inventory. For any structure on the Historic Inventory, Category I or 2, or any landmark structure which is discovered through this process, the definition be strengthened to read "an act or process that destroys or razes in whole or in part a building, structure, or site." b. Permitted Demolition Circumstances Staff recommends that, at minimum, demolition be allowed for either landmark or contributing structures under either one of the following circumstances: Demolition Recommendation 1: The property "as is" cannot be used for any economically viable purpose, and renovation is not economically feasible. Demolition Recommendation 2: The property is determined to represent an imminent safety hazard under PAMC 16.40, and that demolition of the building is the only economically feasible means to secure public safety. In addition to recommending the above criteria for both landmark and contributing structures, Staff presents the following range of options for Council consideration related to demolition policy, recognizing that a variety of other options within and beyond this range are also available: Demolition Option 1: Delay for Both Landmark and Contributing. Continue the current ordinance provisions which allow demolition of pre- 1940 structures except in the Downtown, but strengthen the interim regulations by requiring a demolition delay of up to one year for all landmark and contributing structures. Demolition Option 2: Deny for Landmark/Delay for Contributing. Strengthen the current ordinance provisions by preventing demolition of landmark structures, except under circumstances identified in Demolition Recommendation I and 2, but continue to allow demolition of contributing structures, after requiring a demolition delay of up to one year. Allow alterations to Landmark structures only if National Standards for Historic Preservation have been met. (Refer to Attachment D) CMR: 417:96 Page 7 of 20 Demolition Option 3: Deny for Both, Unless Compatible Replacement Strengthen the current ordinance by preventing demolition of both landmark and contributing structures, except under Demolition Recommendation 1 or 2. Otherwise, do not allow complete demolition of landmark structures under any other circumstances, and allow alteration only when National Standards for Historic Preservation are met. Demolition of contributing structures, both those on the inventory and those with potential to be on the inventory, would be allowed only under certain circumstances. These circumstances-can be selected from the following choices or other options can be developed: a) CompatibiliO, by Staff Approval. The design quality of the replacement structure meets the standards established in the Design Criteria (to be prepared), including criteria which require that the structure is compatible with the pattern of the existing neighborhood and that the replacement is at least equal in design quality to the existing structure; or. b) Compatibili~_ by Design Review. The design quality is approved by the HRB (or other body) to be at least equal to that of the existing structure and is compatible with the pattern and character of the neighborhood, as determined by the discretionary standards (to be prepared) provided in this interim ordinance; and/or c) Condition Hardship The existing facility is seriously deteriorated and it is not economically feasible to renovate (to be defined); While staff is not proposing interior preservation standards, Council will recall from the Varsity Theater entitlement and EIR process that the use of National Standards can result in consideration of interior details. This is particularly germane if financial incentives, like the Mills Act are anticipated to be used, CMR: 417:96 Page 8 of 20 B. Evaluation Policy 1. Evaluation Policy, Pre Moratorium Current standards for evaluation of historic merit are contained in Section 16.49.040(b), and 16.49.020 of the Historic Preservation Ordinance.(Attachment b). These standards were used in 1975 to complete an inventory of historic structures for Palo Alto, and have been used in subsequent years on occasion to update the inventory. Overall, the inventory is outdated and the HRB has recommended that it is in need of update. The City Council adopted a Work Program for 1997-98 which would initiate the Historic Inventory Update, requiring: 1) an evaluation of all historic structures (built over 50 years ago) 2) a determination, after the Historic Protection Ordinance is updated, of corrected designation for structures and properties on the current historic inventory, and 3) a designation of structures determined historically meritorious and worthy of public protection if they are not now on the inventory. A copy of the current regulations .is attached to this report. One of the primary deficiencies identified by the HRB is the current category system. An example of a deficiency is that the landmark categories in Palo Alto’s Ordinance, Categories 1 and 2, only include structures with architectural merit and do not include structures which are valuable cultural resources for reasons other than outstanding architectural merit. This is inconsistent with National Standards for Historic Preservation and creates confusion. 2. Evaluation Policy, Moratorium The Moratorium Ordinance has placed in abeyance the demolition of any pre-1940 structure, whether on the inventory or not, unless they were determined exceptions on September 24.. 1996, to allow time to develop interim regulations. With adoption of the Moratorium, Council has also requested a new time line and cost assessment for expediting the Planning Division Work Program item to update the Historic Inventory. Likewise, Council has directed preparation of interim regulations to allow a temporary process of assessing historic merit for properties which request demolition until such time as the new Historic Preservation Ordinance and Historic Building Inventory can be updated. It is assumed that these regulations will provide for analyzing the historic merit of the building for purposes of protecting those with merit and allowing demolition of those without merit. CMR: 417:96 Page 9 of 20 3. Evaluation Policy Options, Interim Regulations In order to determine whether a structure has historic significance or not, a system of evaluation needs to be used. Council should chose between the following options: 1) decide if it wants to continue to use the current historic designation regulations now contained in Chapter 16.49 (Attachment B), or 2) expand the evaluation classification to include additional factors typically used in up-to-dat historic preservation ordinances, such as including structures of cultural merit in the historic categories. Staff forwarded a copy of the current standards for historic designation to Cherilyn Widell, State Historic Preservation Officer, for her evaluation so that she might recommend changes to bring the existing standards up to par with national standards. She has agreed to perform this analysis quickly for the City, and to assist in a variety. of other ways. (Refer to Attachment C). Her evaluation will be available for the Council by the time of their meeting, but was not available at the time this report was published. Evaluation Option 1: Current Standards. Continue to use the current standards for designation as evaluation criteria for significant historic structures built prior to 1940 Evaluation Option 2: Strengthen Standards. Strengthen the evaluation criteria by updating the standards for designation as recommended by the State Office of Historic Preservation C. Compatibility_ Policy The Council memo and subsequent community discussion raise the issue of whether the current regulations provide sufficient protection to the character and integrity of historic neighborhoods as older residences are replaced by new residences. The Council should decide whether or not to include compatibility criteria in the regulations and whether to administer those through a discretionary or ministerial staff approval process, or a process involving one or more City boards and commissions. This is a highly divisive issue because it implicates individual judgement, property rights, and could affect hundreds, if not thousands, of Palo Altans during home remodeling or rebuilding. 1. Compatibility Policy - Pre-Moratorium The current policy framework for regulating single family design is in the R-1 Zoning Ordinance. As with all of the Palo Alto residential zoning districts, the single- family regulations do not reflect as well the codes used to design traditional CMR: 417:96 Page 10 of 20 neighborhoods, as they do modern suburban zoning standards. While some accommodations for older houses were made during the development of the R-1 regulations, the current R-1 rules were designed primarily to address post 1940 construction. This is because the majoriW of housing stock in Palo Alto was built after World War II. One of the primary reasons for the development of an HIE process was that the pre-1940 housing stock did not fit well into the "box" that was eventually designed for the majority of Palo Alto neighborhoods. However, the HIE process is used exclusively by people remodeling their houses, and is not available for "new residences". There are no compatibility gnidelines or design control requirements in the Historic Preservation Ordinance. HRB recommendations on design or alteration of replacement housing, even in the Professorville National Historic District, are voluntary, although in limited situations they can be enforced by the Zoning Administrator or ARB through another discretionary review process. The single- family residential guidelines are also non-mandatory unless enforced through an exception, variance or ARB approval.. Design review for singly developed single- family residences has been raised and rejected by previous Councils, including in 1989 when the current R- 1 regulations were adopted. 2. Compatibility Policy - Moratorium The Moratorium puts all pre-1940 demolition permits in abeyance until such time as interim regulations can be adopted. The Council has the ability to consider whether or not they want to include compatibility standards in the interim regulations. It is not uncommon to include such criteria in Historic Preservation ordinances. Some historic protection ordinances allow demolition or alteration of "contributing buildings", when necessary, only when a design compatibility finding can be made for the replacement structure prior to approval of the demolition. It should be noted that any type of design review of single family residences has been resisted in the past, however. This is an area of public policy where the community has had strongly divided opinions. Staff is particularly concerned about publicly noticed, discretionary review processes for single-family housing. The amount of staff resources required for mediation between neighbors, the lack of general public education about design and architecture, and the emotion that applicants bring to the process make this type of application potentially divisive and certainly expensive. However, staff acknowledges that the size, design and character of replacement housing is at the core of much negative community reaction to the recent single- family construction boom. The pre-1940 housing stock being demolished includes CMR: 417:96 Phge 11 of 20 some well designed, albeit not necessarily well-maintained, cottages of bungalow, craftsmen, Queen Anne, Tudor, or other traditional style, originally constructed with high-quality and authentic materials. These modest structures are often being replaced with large residences, many of which are designed without the benefit of a licenced architect, constructed of artificial or poorer quality materials and lacking design integrity or the faithful rendering of an architectural style. Some demolitions have taken place for very expensive, well-maintained older residences. The following list outlines the other types of design changes which cause members of the public to react negatively to replacement housing: a. Heights and proportions of new houses are not consistent with the selected architectural style and design, and sometimes it is not possible to determine what style has been selected because elements from many different styles are combined into one residence. b. Whereas pre-1940 residences often used quality materials like real wood siding, rock, brick, shingles, plaster and terra cotta tiles, the new residences are often selecting composite, synthetic, vinyl, stucco, aluminum, fabricated or imitation products and combine traditional features, e.g., cupolas, porches, bay windows, other windows, towers, turrets, gingerbread, and decorative elements in a way that is confusing and inconsistent with traditional architectural style or in a manor that lacks architectural integrity. c. Older residences generally contain windows constructed of real glass and wood. and included true divided light, sills, frames, sashes, mutins, etc... Fenestration and architectural detail were carefully selected for the building facades. The architect generally attempted to create a tasteful and understated design, with attention and respect to balanced proportion. These residences do not call attention to themselves. Many new residences, on the other hand, are using vinyl, metal or plastic windows often with artificial or snap-in grids. They sometimes use arched, angled, octagonal and other combinations of ~vindow shapes without any apparent rationale. Decoration and proportions appear to be designed to call attention to the residence, rather than being based on principles of proper proportion and balance. Sometimes, new residences even include large expanses of blank walls, without any windows. d. Prevalent front yard setbacks in the neighborhood are not being respected with the new construction, and the zoning ordinance does not necessarily allow the traditional prevalent setback to be observed. A modification to the zoning regulations for establishing setbacks by block face in traditional CMR: 417:96 Page 12 of 20 neighborhoods was assigned to staff in 1986, but has never been accomplished due to competing priorities. e~ Traditional homes were generally designed so that building architecture dominated the front facade. A link was usually designed from the private residence to the public realm, through the use of some type of porch or entry feature and walkway, human scaled and properly dimensioned for the architectural style of the house. These features create a "sense of welcome" for the visitor. Many, new residences present the garage doors, which have little architectural merit, as the primary entrance and dominant front facade feature for the house. In some instances, if the new residence contains a porch or entry features, it is designed without pedestrian proportions, as a one a11d one-half or ~’o story element which calls attention to the residence. f. Many traditional residences and neighborhoods have a garage placement pattern of rear-yard garages. The preference of some new home builders is to move the garage doors to the front of the lot, attached to the house. This reduces the amount of human-scaled architecture at the street, and it often results in the immediate removal or damage and eventual removal of street trees for the necessary driveway widening. Because the Council memo did not directly raise the size, or FAR issue, staff has not addressed it in this analysis. Staff would not recommend raising the citywide issue of R-1 regulations until after completion for the Comprehensive Plan, when the Zoning Ordinance Update is initiated, 1997-98. 3. Compatibility Policy Options- Interim Regulations Should Council decide to utilize either Demolition Options 1 or 2, page 7, compatibility criteria would not be needed. Compatibility Design Criteria would only be needed if Council elects to pursue Demolition Option 3 a) or b), page 8. If either option is selected, staff will require direction on the preferred method of implementing these compatibility criteria: Compatibility Option 1: Staff Approval Develop easily enforced (e.g., clear and concise) Design Criteria to achieve compatibility and quality in the replacement structure. These Design Criteria could be prepared and enforced by a professional with expertise in historic/architectural design and could include such provisions as: ) front yard setbacks based on the prevailing setback on the block face, 2) garage placement to CMR: 417:96 Page 13 of 20 match the pattern in the neighborhood, 3) circumstances when pedestrian scaled porches or entry features would be required; 4) listed acceptable quality materials authentic to the style of the house required, and 5) specifications requiring architectural style integrity, while not dictating choice of style. It is assumed that the Design Standards would control pattern, placement. architectural authenticity and quality, of materials, but that style (e.g., Tudor, Queen Anne, modern) would not be controlled. This assumption is based on Palo Alto’s long tradition of welcoming variety in architectural style in most neighborhoods and districts. However. style control is also an option if Council desires. Compatibility Option 2: Design Review. Require design review .for the replacement structure. This option would be a discretionary approval process, presumably with the HR (or other review body) acting as recommending body to the Director of Planning and Community Environment. The review body would test alterations to Landmark structures on the existing Historic Inventory against the National Standards for Historic Preservation (Attachment D), and Contributing Structures against a certain set of discretionary, standards. Guidelines can also be developed to supplement the standards. Discretionary review processes are accompanied by public notification and appeal. It should be noted that involving the HRB in mandatory, discretionary review processes will be a significant change in the HRB’s current functions. This change will require detailed consideration of its implications upon the HRB’s orientation, training, technical staffing, administration, and legal support. II. Procedural Framework In the September 12, 1996 memo, Council members asked staff to construct an interim process whereby any demolition permit would be evaluated by the HRB prior to demolition to determine whether the structure has historic significance and whether the owner has taken all available steps to preserve the structure. The HRB recommendation would be forwarded to the Director of Planning and Community Environment for approval, in the same way that ARB decisions are currently handled. The Director would have three options for the HRB decision - either approve the Decision, return the decision to the HRB for further consideration or forward the decision to City Council. The Director’s decision could be appealed to City Council. CMR: 417:96 Page 14 of 20 The current standards for designation could be used to determine significance, or a ~eater or lesser standard can be quickly developed. (See Evaluation Policy Options 1 and 2, page 10) Staff recommends the following process, depending upon whether a structure is: A) Without Significant Historic Merit; B)Landmark Structure (Category 1 and 2 or suitable for designation as Category 1 and 2); or c)Contributing Structure (Category 3 and 4 or suitable for designation as a Category 3 or 4). A. Structures without Significant Historic Merit If the structure does not meet the standards for designation it would be determined to be without significant historic merit. The HRB would recommend and the Planning Director would approve issuance of a demolition permit. The project would be free to apply for a building permit without further review. B. Landmark Status If a structure is currently Category 1 or 2 or is found by the Board to have potential for landmark status (Category 1 or 2), an historic survey of the property would be required, unless Demolition Recommendation 1 and 2 could be immediately substantiated by the applicant. The survey would be conducted by a qualified professional in historic preservation, restoration and classification. The survey would provide a basis for the HRB’s further evaluation of the request for demolition. The survey would assess whether all reasonable means had been pursued by the applicant to preserve the structure, and would evaluate the condition of the structure and the cost needed to rehabilitate it. 1. Process for Demolition Option 1, (Delay for Both Landmark and Contributing) page 7 The survey, and any information presented by the applicant and community would be the basis of the HRB recommendation and Planning Director decision to require delay of the demolition. Findings related to the merit of the structure; its condition, and the economic feasibility of retaining it would be required. The Director’s decision to grant or delay demolition would be subject to appeal to City Council. CMR: 417:96 Page 15 of 20 2. Process for Demolition Option 2, (Deny for Landmark, Delay for Contributing) page 7 The survey, and any information presented by the applicant and community would be the basis for the HRB recommendation and Planning Director decision to deny or approve the demolition. If denied, the structure would not be allowed to be demolished until the Interim regulations are superseded. At that point, new regulations would then provide the basis for future requirements related to demolition, alteration and historic preservation of the subject structure. The Director’s decision to grant or deny the demolition would be based on findings related to the merit of the structure, it’s condition, and the economic feasibility of retaining it. The decision would be subject to appeal to the City Council. Alterations would be permitted only if they were found consistent with National Standards for Historic Preservation. 3. Process for Demolition Option 3, (Deny for Both, Unless Compatible Replacement) page 7, Same as 2. above. C. Contributin~ Status If a structure is found by the Board to have potential for contributing status (Category. 2 or 3). an historic survey of the property may be required, unless Demolition Recommendations ! and 2, page 7, could instead be substantiated by the applicant, or the HRB and Director have enough information to make the necessary findings without such a survey. The survey, if necessary to make the demolition decision, would be conducted by a qualified professional in historic preservation, restoration and classification, hired by the City and paid for by the applicant. The survey would provide a basis for the the HRB’s further evaluation of the request for demolition. The survey would assess whether all reasonable means had been pursued by the applicant to preserve the structure, and would evaluate the condition of the structure and the cost needed to rehabilitate it. 1. Process for Demolition, Option 1, (Delay for Both Landmark and Contributing) page 7 The survey, if required, and any information presented by the applicant and community would be the basis of the HRB recommendation and Planning Director decision to delay the demolition. Findings related to the merit of the structure, it’s Condition, and the economic feasibility of retaining it would be required. The CMR: 417:96 Page 16 of 20 Director’s decision to want or require delay, of demolition would be subject to appeal to City Council. 2. Process for Demolition Option 2, (Deny for Landmark, Delay for Contributing) page 7 Same as 1. above. 3. Process for Demolition, (Deny for Both Unless Compatible Replacement) Option 3a) and b), page 8 The survey, if required, and any information presented by the applicant and community would form the basis of making decisions that the design quality of the replacement facility is at least equal to that of the existing facility, and compatible with the neighborhood, as determined by the Design Criteria (to be prepared) under Option 3a); or as determined by the HRB in reviewing their standards (to be prepared) during their discretionary design review process under Option 3b). The Director’s decision to grant or delay demolition would be subject to appeal to City Council. 4. Process for Demolition Option 3c), (Condition Hardship), page 8 The survey, if required, and any information provided by the applicant, would provide a basis for determining if the structure meets the definition of"seriously deteriorated" (to be defined). Findings related to the merit of the structure, it’s condition, and the economic feasibility of retaining it would be required. The Director’s decision to grant demolition would be subject to appeal to City Council. ALTERNATIVES Any number of policy and procedural alternatives are available to the Council. A range of policy options has been presented earlier in this report. Procedural alternatives might include: 1). Utilize a staff person as hearing officer and decision maker for the process, similar to the Zoning Administrator, rather than utilizing the HRB. Because the caseload for the Zoning Administrator is at and beyond capacity of one position, it would be recommended that an additional person be contracted to perform this function, preferably an person with considerable experience in historic preservation. This would be the most efficient and least costly option for applicants, however. CMR: 417:96 Page 17 of 20 2) Utilize the ARB as the decision-maker in all or some aspects of the process. Because the ARB are not necessarily qualified in historic preservation, and using both Boards would unnecessarily extend the process and add to the cost, this option is not recommended. 3) Utilize the Planning Commission in some manner in the process. The Planning Commission is also not necessarily qualified to make the required evaluations and recommendations, and including them as well as the HRB would extend the process and increase the cost. 4) City Council, versus the Director of Planning and Community Environment, could be the decision maker on all applications. This has the advantage of providing education and experience with the interim regulations for the Cit?. Council prior to their taking action on the permanent regulations. It has the disadvantage Of extending time lines, using Council agenda time, and creating additional cost. FISCAL IMPACT The costs for administering the interim regulations will be significant and will depend to a large extent on the policy options selected by the City Council and to what extent Council decides to make the interim permit processes subject to cost recovery. The staffing for processing all applications for demolition can be "cost recove13~" and processed by contract staff. Both professional and temporary support staff are likely to be required. The hours and magnitude of staffing will depend to a large extent on the process options selected by Council. For example, by expanding the definition of"demolition", a much greater number of applications will be required and a larger number of hours of contract assistance will be needed. The cost per application will also vary based on Council direction, but could range from 10 hours to 100 hours, or $1,000 to $10,000, or more, depending on whether the item is controversial and/or appealed, and whether or not design review is required. Another cost in the process is the cost of a survey of the structure and property, if it is determined to have potential landmark status, or if the HRB requests a survey for a contributing status structure. These surveys can range in cost from $1,000 to $8,000. It is assumed that while this cost will not be necessary for many of the applications, it would also be billed to the applicant through the cost recovery application. Administrative overhead, included in the hourly fee estimated, will be required to supply printing, mailing, noticing and other costs. If staff administered design criteria are determined to be desirable, they will require professional preparation, a cost estimate for which staff is attempting to obtain estimates. Once Council acts and costs can be estimated, a budget amendment ordinance to cover all costs would immediately be required and sole source contract permission would be sought CMR: 417:96 Page 18 of 20 in order to rapidly obtain contract and/or consultant assistance and temporaw support staff hired to provide administrative services. ENVIRONMENTAL ASSESSMENT Because the interim regulations have been directed to strengthen the City’s Historic Protection Ordinance, preventing demolition of historically significant structures for protection of the environment, the ordinance is categorically exempt from CEQA under a Class 8 Exemption. STEPS FOLLOWING APPROVAL After the Council provides policy and procedural direction, staff will prepare the interim regulations for Council adoption on October 15, 1996. At that time staffwill return with a Budget Amendment Ordinance for implementation of the Interim Regulations and for the revised Work Progam to complete both the Historic Protection Ordinance and Historic Invento~ simultaneously and on a faster time line than anticipated in the budget adoption.

It also forwards Draft Compatibility Review Standards for Replacement Houses and Draft Standards for Historic Designation, additional regulations authorized by the Interim Ordinance. The Interim Regulations and appendix documents will replace the September 17, 1996 Moratorium Ordinance on demolition of older residences. These regulations will be utilized until modified or until they are permanently replaced with an updated Historic Protection Ordinance and Historic Resource Inventory. RE COMMENDATIO,~.S: Staff recommends that the Council: Review and adopt the attached proposed Ordinance establishing Interim Regulations. Direct staff to return the Ordinance to Council for a public hearing in conjunction with the second reading of the Ordinance on October 28, 1996. Preliminary review and direct any needed revisions to the regulations and content outline contained in the Compatibility Review Standards, and direct staff to return with a Resolution and the Standards on October 28, 1996. Preliminary review and direct any needed revisions to the Standards for Historic Designation, and direct staffto return with a Resolution and the Standards on October 28, 1996. CMR:436:96 Page 1 of 9 o o Direct staff to return with a Budget Amendment Ordinance and Fee Schedule for cost recover5, to implement the interim regulations, on October 28, 1996. Adjustments will be necessary’ to both the Planning Division Work Program and budget, as well as the City Attorney budget, for 1996-97 in order to implement the interim regulations and assume the Historic Inventory’ Update assignment. Direct staff to return with an analysis of staff and management impacts associated with new Work Program assignments at the earliest possible date. Direct staff to return on the earliest possible agenda with a budget amendment ordinance to compensate $5,000 to the Comprehensive Plan Publishing Contract, an indirect cost of the Urgency Moratorium. BACKGROUND Background information related to these Interim Regulations has been previously described in the attached report dated September 30, 1996 (CMR:417:96). On September 30, 1996, the City Council provided policy direction to staff regarding the content of the interim regulations. The interim regulations will serve to regulate demolition until the Historic Ordinance and Inventory can be updated. The purpose of this report is to transmit the Draft Ordinance and regulations and to raise policy questions that have come up since the September 30, 1996 Council direction. POLICY IMPLICATIONS A policy framework for guiding the Interim Regulations was presented in CMR:417:96. On September 30, 1996 the Council adopted the following motions providing policy direction to staff on the Interim Regulations: Use Definition of Demolition Option 1, "retain 50 percent perimeter walls" for all contributing structures, and Option 2, "an act or process that destroys or razes in whole or in part a building, structure or site" for landmark structures. o Use Standards for Historic Evaluation Option 2: Strengthen the ev.aluation criteria by updating the standards for designation as recommended by the State Office of Historic Preservation. Designate staff as the first level of review authority for pre-1940 structures not on the inventory, to determine those without significant historic merit. Such decision shall be a publicly noticed procedure, appealable to City Council. o Designate the Historic Resources Board as the second-level review authority for pre- 1940 structures for evaluating and determining whether the structure is of landmark CMR:436:96 Page 2 of 9 status, contributing status, or of no merit. The process for this evaluation would be similar to that now used in the Architectural Review Board ordinance, where the HRB, in a public hearing process, would act as a recommending body to the Director, with appeal to Council. Include the following in the Interim Regulations: Demolition Recommendation 1: The property "as is:’ cannot be used for any economically viable purpose, and renovation is determined not economically feasible; and Demolition Recommendation 2: The property, is determined to represent a safety hazard under PAMC 16.40, and demolition of the building is the only economically feasible means to secure public safety. Include Demolition Option 3a in the Interim Regulations: Stren~hen the current ordinance not to allow complete demolition of landmark structures, except under Demolition Recommendation 1 and 2. Allow alteration of landmarks only when the Secretary,’ of Interior’s Standards for Rehabilitation and the Guidelines for Rehabilitating Historic Buildings are met. Permit demolition of contributing structures only with a compatible replacement structure. A compatible replacement structure will be one where the design quality of the replacement structure meets the standards established in the Design Criteria (to be prepared), including criteria which require that the structure is compatible with the pattern of the existing neighborhood and that replacement is at least equal in design quality to the existing structure. The Compatibility Review will be subject to staff approval based on a set of defined criteria and through a ministerial process. DISCUSSION The attached proposed Ordinance reflects the policy direction provided by Council or contained in the staff report description and accepted in Council discussion at their September 30, 1996 meeting. Likewise, the use of Compatibility Review Standards and Standards for Designation is also based on Council action and discussion. The recommendation to review the Draft Standards documents and continue Council consideration to the October 28, 1996 Council meeting is made, in part, to provide additional time and opportunity for public review and comment. At the Joint Historic Resource Board and City Council meeting of October 7, 1996, a preliminary Draft Ordinance was distributed and presented by the city attorney. Several questions which have arisen since the Council meeting on September 30, 1996 were outlined for Council and the HR]3, and staff recommends that the Council consider these issues and provide any further policy direction if desired. CMR:436:96 Page 3 of 9 Front Facade in the 50 Percent Demolition Rule: A motion to amend the 50 percent demolition rule to include the front elevation of the existing structure failed on a 4 to 5 vote at the September 30, 1996 City Council meeting. Modifications to the front of the house have the most dramatic impact on neighborhood character and context. By including the front facade in the definition, additional neighborhood compatibility will be achieved in those projects which "escape" the Interim Regulations by designing beneath the 50 percent threshold. Staff recommendation." Staff recommends that this amendment be included in demolition definition, and the proposed ordinance reflects this change. "Fences and Paint": At the October 7, 1996, joint meeting the issue was raised about whether the City should have jurisdiction over changes to landmark structures that do not require permits from the City, such as fences or paint modifications. Staff recommendation: Staff recommends that review jurisdiction not be extended to consider these non-permit activities when they are undertaken independently by the property, owner, but that these items be reviewed if the project is subject to the Interim Regulations through permit application. No change to the Draft Ordinance is required. Designation Moratorium: Staff has raised a concern that structures are likely to be. discovered to be significant through the Interim Regulations, but that applicants may withdraw and amend plans below the 50 percent threshold in order to escape Compatibility Review or review according to National Standards. Under the current ordinance, it would be possible for applicants to escape the Interim Regulations by redesigning the demolition to an "addition." Staff recommendation: Should the Council want to prevent this outcome, staff would recommend an amendment to Section 16.49.040 to impose a demolition or alteration moratorium at the time the historic designation is proposed. The moratorium would last until the application had been finally considered by Council. Evaluations Possible without Demolition Permit Application: The ordinance has been drafted to allow owners to seek historic evaluations from the City without needing to apply for a demolition permit. Staff recommendation: No change to the Draft ordinance is necessary. Direct Referral to HRB for an Evaluation: Ifa structure has obvious historic merit, and both the Director and the applicant agree that the initial staff review is CMR:436:96 Page 4 of 9 unnecessary, a time and cost saving measure has been included in the ordinance which allows direct referral to HRB. Staff recommendation. Staff recommends that direct referral be permitted and no change in the Draft Ordinance is necessary. Exceptions to the Compatibility. Standards: It is not possible to develop design or site development standards which apply to all circumstances. There needs to be an exception process for any ministerially administered regulations in order to accommodate unforeseen and unusual circumstances which create the wrong results. Staff recommendation." Staff recommends that an exception process which allows the applicant to seek relief from the Compatibility Standards be made available. The process should involve a staff-conducted hearing opportunity, and a decision by the Director, and should be based on findings that the proposed alternative better achieves design quality and compatibility with the existing neighborhood than would the strict application of the Compatibility standards. ALTERNATIVES Any number of alternatives are available to the Council. A range of policy options has been presented earlier in CMR:417:96, but these alternatives were not selected by Council. Staff recommends that a four month status on the Interim Regulations return to Council for evaluation. At that time, it may be necessary to examine new alternatives or reexamine alternatives that were not previously selected. FISCAL IMPACT The costs for administering the interim regulations will be significant. The cost of moving forward Item 39 of the Planning Division Work Program will also be significant. The following discussion projects some of the specific costs, and identifies generally other, as yet unquantified, costs. Staff is currently analyzing and estimating the full costs and will return to Council with our analysis at the earliest possible agenda. In the meantime, we are implementing Council direction with existing resources, by placing other assignments on hold, based on priorities in the Work Program, until such time as we can return to Council for additional resources and re-prioritization of the Work Program. Immediate Direct Budget Impact The initial assignment, drafting and publishing Compatibility Standards and setting up administrative procedures for all interim regulations, will cost approximately $13,000. This funding is to be taken from the Manager’s Contingency Fund, because the task needed to CMR:436:96 Page 5 of 9 initiate immediately in order to meet the Council directed time line, and could not wait for Council adoption of a Budget Amendment Ordinance. The ongoing cost of processing the various applications cannot be precisely determined. Staff recommends that cost recove~ be utilized for the new processes. Deposits ranging from $300 to $1,500 will be collected based on hourly estimates for the minimum hours projected to process each application type independently (refer to Attachment D). When multiple applications are filed, only the highest deposit is collected, and accounting of time for all related applications will be billed against that deposit and to the applicant. Ifa project is complex and controversial the cost will go up. If it is simple and straight forward it will take less time. Staff estimates that between $1,000 to $10,000 could be charged to a typical applicant, but because we have no prior experience with the proposed processes, staff will keep account of the time spent. A status report to Council will be made in four months. At that time, Council can reexamine the cost of these regulations and whether cost recovery to applicants is the desirable policy. Staff intends to return with a Budget Amendment Ordinance for $75,000 to initiate the Interim Ordinance Administration. Staff expects that amount to last at least until the four month review period expires, based on the rate of demolition permits we have been experiencing and assuming a range of application costs. Immediate Indirect Budget Impact Staff temporarily reassigned to the Interim Regulations were working primarily on Phase IV of the Comprehensive Plan and the Downtown Improvement CIP. The Comprehensive Plan is in transition from editor to publisher and nearing draft document publication. The week the Council adopted the moratorium was a critical one in the Comprehensive Plan publication task. The publishing contractor assumed tasks that were to be accomplished by a staffplarmer, temporarily assigned to the Urgency Moratorium. The publishing contractor, through a change order, coordinated several aspects of our desk top publication assignment and graphic formatting during that weel~. The cost to our contract of reassigning a staff planner to the Urgency Moratorium was approximately $5,000. Staff will be returning to Council with a budget amendment ordinance to recover that amount in order to meet our obligation to publish the Draft Comprehensive Plan. The time line for release of the Draft Plan was also impacted by a minimum of one week. Immediate Work Program Impacts In addition to the Comprehensive Plan, the Work Program Item which has been most impacted by the Interim Regulations is the Downtown Urban Design Improvements CIP, Item 6. We have notified the consultant that the project is on hold and between a one- and two-month delay in this project is expected. It has always been staff’s intent, as reflected in the Scope of Services, to allow the newsrack portion of the project to proceed independently of the other improvements. This is still our objective should the Steering Committee CMR:436:96 Page 6 of 9 recommend that installation move forward. The remainder of the project will be delayed. however. Other Impacts Two additional difficulties arise from the assignment to accomplish Interim Regulation ¯ administration. One is the need for office space in the Planning Division. There is no room on the fifth floor of City Hall to accommodate coordination with additional contract personnel. In this instance, the contract personnel will need to work closely with single- family homeowners and applicants, and there is no room for this coordination. The City Manager is committed to seeking a temporary solution to this problem. This space and related furnishings will need to be obtained by late November. The second impact relates to the growing amount of contract assignments, contract management and oversight, and increasing cost-recovery permit activity associated with development in Palo Alto. In 1992 the Division employed one contract planner and administered 12 contracts and five blanket orders. Today the Division manages five contract planners, 25 contracts and nine blanket orders. It is increasingly difficult to competently manage and accept additional assignments within current management and staffing levels. The Interim Regulations will result in the need for an additional contract planner, one contract support staff, and other contract capabilities. This Interim Ordinance assignment, coupled with the new responsibilities for the Heritage Tree Ordinance and Planning Arborist, exceeds our management capacity. Temporarily, managers and staff are working overtime to compensate for the lack of resource, but that level of commitment cannot be sustained. If it is assumed that an ongoing commitment of resources to Historic Preservation and increased support to the HRB are likely to come from the permanent regulations, as has resulted from the Interim Regulations, it is prudent to reexamine permanent management and staffing needs to accomplish these additional responsibilities. Management and staffing issues will be addressed at the earliest possible time. Longer Term Impacts to Budget and Work Program While the Historic Ordinance Update, Item 12 of the Division Work Program, was already included in the assignments for FY 1996-97, the Historic Resource Inventory, Item 39 of the Work Program, was not. The most significant foreseeable effect of a new Work Program assignment is the likely delay of the Permit Tracking/Condition Monitoring assignment, Item 35. The Historic Inventory is partially automated, and moving the assignment forward raises immediately questions of hardware capacity, systems support, and special programming costs. Some of these costs may be available through the GIS CIP, but coordinating with the CIP committee will take additional time in order to provide reliable estimates. CMR:436:96 Page 7 of 9 Likewise, in order to accommodate a "fast-track" time line, the previously assumed budget, which relied on a longer time line for consultant assistance, will need to be revised. Finally, it is worth noting that the State Officer of Historic Preservation has alerted the CiB~ to the possibilities of recovering some of these costs through available grants and she has offered her assistance to us in preparing the applications. Grants could be available to offset some of the costs, but the resources to investigate and prepare applications will need to be found. Staffwill develop a scope and budget for the long-range assignment, and we intend to return to Council as soon as possible with a complete assessment, cost proposal and scope of services. All issues associated with management of contracts, space, etc.. are further exacerbated with the additional new long-range assignment. ENVIRONMENTAL ASSESSMENT Because the interim rega~lations have been directed to strengthen the City’s Historic Protection Ordinance, preventing demolition of historically significant structures for protection of the environment, the ordinance is categorically exempt from CEQA under a Class 8 Exemption.
