If a tax map parcel has more than one owner, all such owners must sign any petition mentioned in this section before the parcel shall be counted as supporting the petition and the parcel shall receive only one vote, regardless of the number of owners.

(2) A petition to designate a landmark or historic district shall be on a form provided by the director of planning and development and approved by the historic preservation commission. The petition shall clearly identify all historic and architectural features proposed for regulation. The petition shall identify the facts which support a determination that the proposed landmark or historic district meets the criteria for designation set forth in this section. The petition shall be filed with the director of planning and development. Except as otherwise provided in this section, the petition shall be handled in the same manner as a petition for rezoning. Prior to setting a date for a public hearing before the planning and zoning commission, the director of planning and development shall forward a copy of the petition to the historic preservation commission for its review. The historic preservation commission shall prepare a report to the planning and zoning commission and the city council setting forth its recommendation on whether the proposed landmark or historic district meets the criteria for designation set forth in this section.

(3) The ordinance placing property within overlay district HP shall designate the property as a landmark or as an historic district. The ordinance may designate a structure within an historic district as a landmark. The ordinance shall identify all historical and architectural features that shall be subject to regulation. No interior features shall be identified in any structure in an historic district unless the structure is designated as a landmark.

(4) Overall boundaries for local historic districts shall be determined by the same standards used by the National Register of Historic Places, as laid out in Defining Boundaries for National Register Properties: National Register Bulletin 21 (Washington D.C.: U.S. Department of the Interior, 1995). Gerrymandering which has the apparent effect of overwhelming significant areas of opposition is prohibited.

(g) Certificate of appropriateness; when required. A certificate of appropriateness shall not be required for interior construction or alteration of any structure in an historic district unless the structure has been designated a landmark. A certificate of appropriateness shall be required before the following actions affecting any historic or architectural feature identified in the ordinance placing the property in district HP may be undertaken:

(1) Any construction, alteration, removal, or any demolition in whole or in part regardless of whether a permit from the city is required.

(2) Any construction, alteration, removal or demolition, in whole or in part, proposed by the city, for a city owned landmark or structure within an historic district.

(h) Certificate of appropriateness; procedure.

(1) An application for a certificate of appropriateness shall be made on forms provided by the director of planning and development and approved by the historic preservation commission. The application shall identify the facts which support a determination that the proposed actions meet the standards for review and design guidelines set forth in this section.

(2) After determining that the application for certificate of appropriateness is complete, the director of planning and development shall schedule the application for consideration by the historic preservation commission within a reasonable time. If a fully completed application for a certificate of appropriateness has not been acted upon within forty (40) days after the date the application was filed with the director of planning and development, it shall be deemed approved, unless tabled or continued with the consent of the applicant. No motion to table or continue shall be made without the consent of the applicant. The director of planning and development shall conspicuously place a sign on the property giving public notice of the meeting at which the application shall be considered. The sign shall be placed at least seven days prior to the meeting.

(3) Any person aggrieved by the decision of the historic preservation commission may appeal to the board of adjustment by filing a notice of appeal with the city clerk within 30 days of the decision of the historic preservation commission. Notice of the historic preservation commission’s decision shall be mailed to the applicant unless the applicant or the applicant’s agent was present at the meeting at which the decision was made. The board of adjustment shall provide a hearing and render a decision in accordance with the provisions of chapter 536 RSMo.

(i) Certificate of appropriateness; standards for review and design guidelines. In considering an application for a certificate of appropriateness, the historic preservation commission shall be guided by the following standards, and design guidelines in addition to any area-specific design guidelines included in the ordinance designating the landmark or historic district.

(1) Reasonable efforts shall be made to provide a compatible use for a property which requires minimal alteration of the

building, structure or site and its environment, or to use a property for its originally intended purpose.

(2) The distinguishing original qualities or character of a building, structure or site and its environment shall not be destroyed. The removal or alteration of any historic material or distinctive architectural features should be avoided when possible.

(3) Building alterations that have no historical basis and which seek to create an earlier appearance shall not be allowed.

(4) Changes which may have taken place in the course of time are evidence of the history and development of a building, structure or site and its environment. When these changes have acquired significance in their own right, they shall be

treated the same as if they were part of the original structure.

(5) Distinctive stylistic features or examples of skilled craftsmanship which characterize a building, structure or site shall be preserved when possible.

(6) Deteriorated architectural features shall be repaired, rather than replaced, whenever practicable. If replacement is necessary, the new material should match the material being replaced in design, color, texture, and other visual qualities. Repair or replacement of missing architectural features shall be based upon accurate duplication of features, substantiated by historic, physical or pictorial evidence, rather than on conjectural designs or the availability of different architectural elements from other buildings or structures.

(7) The surface cleaning of structures shall be undertaken with the gentlest means possible. Sandblasting and other cleaning methods that will damage the historic building materials shall not be undertaken.

(8) Every reasonable effort shall be made to protect and preserve archaeological resources affected by or adjacent to any project.

(9) Contemporary design for alterations and additions to existing properties and for new construction may be permitted when such alterations, additions or new construction do not destroy significant historical, architectural or cultural material, and such design is compatible with the size, scale, material and character of the property, neighborhood or environment.

(10) Whenever possible, new additions or alterations to structures shall be done in such a manner that, if such additions or alterations were to be removed in the future, the essential form and integrity of the structure would be unimpaired.

(11) The height of any proposed alteration or construction shall be compatible with the style and character of the landmark and with surrounding structures.

(12) The proportions and relationships between doors and windows shall be compatible with the architectural style and character of the landmark, and with surrounding structures.

(13) The relationship of a structure to the open space between it and adjoining structures should be compatible.

(14) The design of the roof should be compatible with the architectural style and character of the landmark and surrounding structures.

(15) The scale of the structure after alteration, construction or partial demolition should be compatible with its architectural style and character and with surrounding structures.

(16) Facades should blend with other structures with regard to directional expression. Structures should be compatible with the dominant horizontal or vertical expression of surrounding structures. The directional expression of a landmark after alteration, construction or partial demolition should be compatible with its original architectural style and character.

(17) Architectural details including materials and textures should be treated so as to make a landmark compatible with its original character or significant architectural style and to preserve and enhance the landmark or historic district.

(j) Certificate of economic hardship.

(1) A person whose application for a certificate of appropriateness has been denied or granted conditionally may apply for a certificate of economic hardship. Alternatively, an application for a certificate of economic hardship may be filed with the application for certificate of appropriateness. Application shall be made on forms provided by the director of planning and development and approved by the historic preservation commission. If a fully completed application for a certificate of economic hardship has not been acted upon within forty (40) days after the date the application was filed with the director of planning and development, it shall be deemed approved, unless tabled or continued with the consent of the applicant. No motion to table or continue shall be made without the consent of the applicant. The application shall identify facts which support a determination that denial of the application will deprive the owner of the property of reasonable use of or a reasonable economic return on the property.

(2) An application for certificate of economic hardship may include the following information:

a. Estimate of the cost of the proposed construction, alteration, demolition or removal and an estimate of any additional cost that would be incurred to comply with the recommendations of the historic preservation commission for changes necessary for the issuance of a certificate of appropriateness.

b. A report from a licensed engineer or architect with experience in rehabilitation as to the structural soundness of any structures on the property and their suitability for rehabilitation.

c. Estimated market value of the property in its current condition; after completion of the proposed construction, alteration, demolition or removal; after any changes recommended by the historic preservation commission; and, in the case of a proposed demolition, after renovation of the existing property for continued use.

d. In the case of a proposed demolition, an estimate from an architect, developer, real estate consultant, appraiser, or other real estate professional experienced in rehabilitation as to the economic feasibility of rehabilitation or reuse of the existing structure on the property.

e. Applicant may demonstrate with factual data/evidence that the hardship is not self-created. If the property is income producing, the applicant may provide detailed annual income and expense reports for the property for the last two years, rent rates and capitalization rates for the property and comparable properties, and any other pertinent information that would substantiate the applicant’s claim concerning economic hardship.

f. Appraisals obtained within the previous two years by the owner or applicant in connection with the purchase, financing or ownership of the property.

g. Any listing of the property for sale or rent, price asked and offers received, if any, within the previous two years.

The board of adjustment shall provide a hearing and render a decision in accordance with the provisions of chapter 536 RSMo.

(k) Continuing validity of certificates. Certificates of appropriateness and certificates of economic hardship shall become void if the work authorized by the certificate is not commenced within six months of the date of issuance. Certificates of appropriateness and certificates of economic hardship shall be issued for a period of eighteen months and are renewable.

(l) Stop work orders. The director of public works is authorized to issue a stop work order under the procedures set forth in the building code adopted in chapter 6 of this code when any work on any structure requiring a certificate of appropriateness is being performed without a certificate of appropriateness or a certificate of economic hardship or in violation of the terms of a certificate of appropriateness or a certificate of economic hardship.

(m) Signs. Signs in District HP are subject to the general sign regulations of the code of ordinances. In addition, all signs for a landmark or structures in a historic district not specified in the application for landmark or historic district designation must receive a certificate of appropriateness from the historic preservation commission, which shall review the proposed sign in accordance with the following general guidelines:

(1) Additional sign restrictions included in the ordinance which designates a landmark or historic district.

(q) Variances. The historic preservation commission may make recommendations to the board of adjustment to allow variances for standard parking and lot line requirements for property in district HP, where such variances will aid in the retention of the property's historic character and appearance. The historic preservation commission shall also make recommendations to allow designated properties to be utilized for non-complying uses if such use would serve to perpetuate the viable contemporary utilization of the historic structure.

(r) Violations. In addition to the penalties provided for in this chapter, any person who undertakes or causes an alteration, construction, demolition or removal of any designated landmark or property within a historic District in violation of this ordinance shall be required to return the landmark or property to its appearance and setting prior to the violation.
