§ 18.63.040 Riverton historic sites list.
Created. There is hereby created a Riverton historic sites list (the "list"), which shall serve as a means of providing recognition to and encouraging the preservation of historic resources in the city. The list shall be prepared and maintained by the historic preservation commission and filed with the city recorder's office. Owners of property where historic sites are found shall be notified by the city recorder's office that a site found on the owner's property has been included on the list.
Contents. The list shall describe each historic resource included therein, the date or approximate date of its construction, the date during which its historic significance was established, the reason for including it on the list, and the name and address of the current owner as shown on the records of the Salt Lake County recorder.
Criteria. The historic preservation commission may designate any building, structure, object, site or district to the list as a historic resource in accordance with the procedures set forth herein if it is determined by the historic preservation commission that the historic resource meets all of the following criteria:
Notification. The owner of the item under consideration for inclusion on the list shall be notified in writing either by certified mail or hand delivery of the proposed action to designate the historic resource to the list and shall be invited to attend the historic preservation commission meeting in which the designation will be discussed. Said notification shall be provided as described herein not less than 14 days prior to the date of the historic preservation commission meeting in which the designation will be discussed.
Designation Procedures. The historic preservation commission is charged with designating properties to list, and to maintain the same. The list shall reference any research related to the historic resource and a copy of the list shall be kept in the historic preservation commission's historic sites files. The historic sites files shall be open to the public in accordance with the Utah Governmental Records Access and Management Act. This list shall be reviewed and historic resources shall be added or deleted as appropriate on, at minimum, a yearly basis by the historic preservation commission. The list should include historic resources located within the city that meet the minimum requirements set forth below:
The historic resource is rated an "A" or "B" on a professional reconnaissance level survey;
The historic resource is deemed "A" or "B" by the historic preservation commission (for properties outside of a surveyed area);
A historic resource that does not meet the "A" or "B" criteria established by the National Register of Historic Places may nonetheless be included if it is of exceptional importance to Riverton's history; or
Any historic resource that has undergone major alterations or has been destroyed may be identified by markers placed on the original site of the historic resource with city council approval; and
The designation under consideration is not objected to by the owner of the historic resource.
Results of Designation.
Certificate. The owner of an officially designated historic resource may obtain an historic site certificate from the historic preservation commission. The certificate shall contain the historic name of the property, the date of designation, and signatures of the mayor and the historic preservation commission chairperson.
Plaque. The owner of an officially designated historic resource may obtain a historic site plaque from the historic preservation commission. Said plaque will be paid for by the historic preservation commission; however, replacement of the plaque at any future date will be the responsibility of the owner of the historic site.
Demolition. If a historic resource is to be demolished or undergo major alterations, efforts shall be made by the historic preservation commission to document its physical appearance before that action takes place.
The city shall delay issuing a demolition permit for a maximum of 10 calendar days and shall notify a member of the historic preservation commission, who will take responsibility for the documentation.
Documentation shall include, at a minimum, exterior photographs of all elevations of the historic resource. When possible, both exterior and interior measurements of the building will be made in order to provide an accurate floor plan drawing of the building.
A demolition permit shall be issued after a period 10 calendar days from the initial date of permit application whether or not the historic preservation commission has documented the building. The permit may be issued earlier if the historic preservation commission has completed its documentation before the 10-day deadline.
Documentation shall be kept in the historic preservation commission's historic sites files, which shall be open to the public in accordance with the Utah Government Records Access and Management Act.
Removal of Properties. If, after review and consideration by the historic preservation commission, it is determined that a historic resource no longer meets the criteria for listing, the historic preservation commission may remove the historic resource from the list. A property owner where an historic resource is found may request removal of the historic resource from the list, by submitting a request in writing to the city recorder's office, who shall promptly notify the historic commission of the written request. The historic commission shall remove an historic resource from the list within 10 calendar days following the city recorder's receipt of a written request. The historic commission shall use reasonable efforts to document the historic resource prior to its removal from the list.

§ 18.63.050 Riverton historic landmarks register.
Created. There is hereby created a Riverton historic landmarks register (the "register"), which shall provide further recognition of significant historic resources; provide protection for historic resources as set forth in this chapter; and may qualify owners of historic resources to special assistance from the city as may be determined by the city council in its sole discretion. The register shall be prepared and maintained by the historic preservation commission in accordance with the provisions set forth in this chapter. A notice of listing shall be filed for each property listed on the register with the city and recorded in the office of the Salt Lake County recorder. Owners of property where historic landmarks are found shall be notified by the city recorder's office that a landmark found on the owner's property has been included on the register.
Contents. The register shall describe each historic resource, the date or approximate date of its construction, the date during which its historic significance was established, the qualifications for including it on the register, and the name and address of the current owner of the property as shown on the records of the Salt Lake County recorder.
Criteria. Any historic resource may be designated to the register in accordance with the procedures set forth herein if it meets all the criteria set forth below:
The historic resource is located within the corporate boundaries of Riverton City;
The historic resource is currently listed in the National Register of Historic Places (the "National Register"), or it has been officially determined eligible for listing in the National Register under the criteria of 36 C.F.R. 60.4, as amended.
The historic resource shall also meet at least two of the following criteria:
It is an easily identifiable visual feature of its neighborhood or the city because of its positioning, location, age, scale or style, and it contributes to the distinctive quality or identity of its area in such a way that its absence would negatively affect the area's sense of place;
It figures importantly into Riverton's founding or development through its uses, especially public uses;
It is associated with persons significant in the founding or development of Riverton, especially the earliest settler families (1847 – 1900);
It is associated with events that have made a significant contribution to the founding or development of Riverton;
It illustrates an important architectural form, style, or building technique, especially as an example of "local vernacular" (e.g., single- and two-story rock/adobe homes; simple brick Victorians) or as a singular example of form, style, or technique within the city;
It has been used as a way-finding landmark for at least 50 years; or
It has yielded, or may be likely to yield, information important in prehistory or history (e.g., archaeological sites).
If a historic resource does not meet at least two of the criteria of subsection (3)(c) of this section, but is of exceptional importance to Riverton's history and the owner of the property wishes to have it designated as a historic resource on the register, the historic preservation commission may review the request and, if deemed suitably significant, may recommend to the city council that the historic resource be added to the register.
Notification. The owner of the historic resource shall be notified in writing either by certified mail or hand delivery of proposed action to designate the historic resource to the register and shall be invited to attend the historic preservation commission meeting in which the designation will be discussed.
Designation.
Official designation proceedings shall begin with submittal of a written request for designation by either the property owner or a member of the historic preservation commission. The request shall identify the property by its address and historic name, give the date the property was listed in the National Register or officially determined eligible, and include a statement summarizing the property's significance to the city. This official request may be preceded by informal contacts with the property owner by historic preservation commission members, private citizens, local officials, or others regarding designation of the property.
Upon written request for designation, the historic preservation commission chairperson shall arrange for the designation to be considered at the next historic preservation commission meeting, which shall be held at a time not to exceed 30 days from the date the designation request was received.
A decision by the historic preservation commission shall be based on whether the property meets the criteria for designating properties to the register as set forth in subsection (3) of this section. The historic preservation commission shall forward its recommendation in writing to the city council within 14 days of the decision.
The city council may, by adoption of an appropriate resolution, designate a historic resource to the register. The owner of the historic resource shall be notified at least three days prior to the city council meeting at which the ordinance will be considered and shall be allowed to address the council with regard to the designation. Following designation, a notice of such shall be mailed to the owners of record.
A historic resource which, in the opinion of the historic preservation commission, no longer meets the criteria for eligibility may be removed from the register after review and recommendation by the historic preservation commission and the adoption of an appropriate ordinance by the city council.
Upon official adoption of a designating or removal ordinance, the historic preservation commission shall record proper notice with both the city recorder's office and the county recorder's office to indicate such designation or removal on the official records thereof.
Result of Designation.
An owner of a historic resource listed on the register may seek assistance from the historic preservation commission in applying for grants or tax credits for rehabilitating the owner's properties.
Proposed repairs, alterations, additions, relocation or demolitions to historic resources listed on the register requiring a building permit are subject to review by the historic preservation commission and shall receive a "certificate of historic appropriateness" prior to issuance of a building permit. The purpose of this review is to ensure the preservation of historic resources to the greatest extent reasonably possible.
Any application for a building permit pertaining to a historic resource designated on the register shall be forwarded by the zoning administrator to the historic preservation commission for its determination prior to the issuance of the requested permit.
At its next scheduled meeting, the historic preservation commission shall review the application and proposed work for compliance using the United States Secretary of the Interior's Standards for Rehabilitation, in effect at the time of the scheduled meeting.
The historic preservation commission's determination shall be forwarded within three days to the zoning administrator for review. If the historic preservation commission denies or requires significant revisions to a permit application, the determination shall indicate the specific standards on which the decision of the historic preservation commission is based and, where appropriate, shall provide a brief explanation setting forth the reasons for the determination. Copies of the determination shall be forwarded by the zoning administrator to the property owner.
The zoning administrator shall, upon receipt of the historic preservation commission's determination, process the permit as set forth in this section. Projects which, as determined by the historic preservation commission, are consistent with the standards shall be issued a certificate of historical appropriateness which authorizes the building permit to be issued upon compliance with all other applicable requirements of this title or any other applicable ordinance.
An applicant whose submittal does not comply with the standards may, for a period of 60 days, meet with the historic preservation commission, together with the zoning administrator, to explore means for proper repair, alteration or addition to the historical resource which are consistent with the standards, which may include the following:
If no approval is granted within the initial 60 days, the historic preservation commission may grant an extension of an additional 60 days. If no approval is granted at the conclusion of 120 days, the certificate of historic appropriateness shall be denied if the standards for rehabilitation cannot be met and the requested building permit shall not be issued by the zoning administrator until the historic resource is removed from the register or list, following documentation of the historic resource described in this chapter.
A decision by the historic preservation commission approving or denying a certificate of historic appropriateness for the relocation of a historic resource shall be guided by the following criteria:
How the historic character and aesthetic interest the historic resource contributes to its present setting;
Whether there are definite plans for the area to be vacated and what the effect of those plans on the character of the surrounding area will be;
Whether the historic resource can be relocated without significant damage to its physical integrity; and
Whether the proposed relocation area is compatible with the historical and architectural character of the historic resource.
A decision by the historic preservation commission approving or denying a certificate of historic appropriateness for the demolition of a historic resource listed on the register shall be guided by the following criteria:
The historic, scenic or architectural significance of the historic resource;
The importance of the resource to the character of the neighborhood or city;
The difficulty or the impossibility of reproducing the historic resource because of its design, texture, material, detail, or unique location;
Whether the historic resource is one of the last remaining examples of its kind in the neighborhood or city;
Whether there are definite plans for use of the property if the proposed demolition is carried out, and what the effect of those plans on the character of the surrounding area would be;
Whether reasonable measures can be taken to save the historic resource from deterioration or collapse; and
Whether the historic resource is capable of being used to earn a reasonable economic return on its value.
A certificate of historical appropriateness shall become void unless construction authorized by a building permit is commenced within 180 days after issuance of the certificate.
Ordinary maintenance and repair of any exterior architectural or environmental feature in or on a historic resource to correct deterioration, decay, or to sustain the existing form, and that does not involve a material change in design, material or outer appearance thereof, does not require a certificate of historic appropriateness.
An owner of a historic resource listed on the register shall not allow any building to deteriorate by failing to provide ordinary maintenance or repair. The historic preservation commission shall be charged with the following responsibilities regarding deterioration by neglect:
The historic preservation commission shall monitor the condition of historic resources to determine if any historic resource is being allowed to deteriorate by neglect. Conditions such as broken windows, doors and exterior openings which allow the elements to enter or otherwise become an attractive nuisance, or the deterioration of a historic resource's structural system shall constitute failure to provide ordinary maintenance or repair.
In the event the historic preservation commission determines there is a failure to provide ordinary maintenance or repair, the historic preservation commission shall notify the owner of the historic resource and set forth the steps which need to be taken to remedy the situation. The owner of the historic resource shall have 30 days to make necessary repairs.
In the event that the condition is not remedied in 30 days, the historic preservation commission may remove the historic resource from the register. This section shall not be construed as a limitation to other enforcement actions which may be undertaken by Riverton City in accordance with other statutes or ordinances.
When, by reason of unusual circumstance, the strict application of any provision of subsection (5) of this section would result in exceptional practical difficulty or undue economic hardship upon any owner of a historic resource, the city council, with recommendation from the historic preservation commission, shall have the power to modify strict provisions, so as to relieve such difficulty or hardship; provided, such modifications or interpretations shall remain in harmony with the general purpose and intent of said provisions, so that the architectural or historical integrity, or character of the historic resource, shall be conserved and substantial justice done. In granting modifications, the city council, with or without recommendation from the historical preservation commission, may impose such reasonable and additional stipulations and conditions as will, in its judgment, best fulfill the purpose of this chapter. Undue hardship shall not include a situation of the person's own making.
A person who alleges that action by the historic preservation commission or the city will result in an unconstitutional taking of property may request a review thereof as provided in Riverton City Code.
Enforcement. Failure to follow the procedure for acquiring a certificate of historical appropriateness may result in the zoning administrator issuing a stop-work order while a review is conducted. The review will determine if revocation of a conditional use permit granted for a use associated with the historic resource, revocation of building permits and/or other penalty fines are necessary as per Chapter 18.220 RCC, Regulatory Provisions.
Failure to follow the procedure set forth in this chapter for acquiring a certificate of historic appropriateness may result in removal of the historic resource from the register and the National Register, thus rendering the property ineligible for federal, state, and city tax credits, grant and loan programs.
In addition, if the historic resource has received land use entitlements as a result of its placement on the register, the city may consider the revocation of such entitlements and/or the acceleration of any debt issued by the city as part of a program of historic preservation/rehabilitation consistent with applicable law.
(Ord. 16-11 § 1 (Exh. A))
§ 18.63.060 Standards for rehabilitation.
The following standards for rehabilitation shall be used when determining the historic appropriateness of any application pertaining to a historic resource:
A property shall be used for its historic purpose or be placed in a new use that requires minimal change to the defining characteristics of the building and its site and environment.
The historic character of a property shall be retained and preserved. The removal of historic materials or alterations of features and spaces that characterize a property shall be avoided.
Each property shall be recognized as a physical record of its time, place, and use. Changes that create a false sense of historical development, such as adding conjectural features or architectural elements from other buildings, shall not be undertaken.
Most properties change over time; those changes that have acquired historical significance in their own right shall be retained and preserved.
Distinctive features, finishes, and construction techniques or examples of craftsmanship that characterize a historic property shall be preserved.
Deteriorated historic features shall be repaired rather than replaced. Where the severity of deterioration requires replacement of a distinctive feature, the new feature shall match the old in design, color, texture, and other visual qualities and, where possible, materials. Replacement of missing features shall be substantiated by documentary, physical, or pictorial evidence.
Chemical or physical treatments, such as sandblasting, that cause damage to historic materials shall not be used. The surface cleaning of structures, if appropriate, shall be undertaken using the gentlest means possible.
Significant archaeological resources affected by a project shall be protected and preserved. If such resources must be disturbed, mitigation measures shall be undertaken.
New additions, exterior alterations, or related new construction shall not destroy historic materials that characterize the property. The new work shall be differentiated from the old and shall be compatible with the massing, size, scale, and architectural features to protect the historic integrity of the property and its environment.
New additions and adjacent or related new construction shall be undertaken in such a manner that if removed in the future, the essential form and integrity of the historic property and its environment would be unimpaired.
(Ord. 16-11 § 1 (Exh. A))
§ 18.63.070 Appeals.
Any person adversely affected by any final decision of the zoning administrator in the administration of this chapter may appeal such decision to the board of adjustment in accordance with Chapter 2.80 RCC.
Any person adversely affected by any final decision of the historic preservation commission in the administration of this chapter may appeal such decision to the city council in accordance with the provisions of this section.
Appeals shall be taken within 15 days of a written decision by filing a written notice with the city manager, specifying the grounds for appeal. Only grounds specified in the appeal shall be considered by the council.
An appeal stays all proceedings in furtherance of the action appealed from unless the historic preservation commission certifies to the city council that, by reason of fact stated in the certificate, a stay would cause imminent peril to life or property. In such cases, proceedings shall not be stayed otherwise than by restraining order which may be granted by the appropriate appeal body or by the District Court on application and notice and on due cause shown.
The city council shall schedule a public hearing to hear the appeal. Notice of the hearing shall be given at least 15 days prior to the hearing. Notice of the hearing shall be made as required by law. The city council may modify the order, requirement, decision or determination appealed from and may make such determination as ought to be made and to that end shall have all powers of the historic preservation commission. A concurring vote of a simple majority of the total membership of the council shall be necessary to act on the appeal.
Any person adversely affected by any final decision of the city council designating a historic resource to the register, or regarding an appeal from a decision of the historic preservation commission in the administration of this chapter may have and maintain a plenary action for relief therefrom in a court of competent jurisdiction; provided a petition for such relief is presented to the court within 30 days after the rendering of such decision.
