Process for Designating Properties to the Town Register of Historic Places.
(a) 
Any person may nominate a building, structure, site or object for inclusion in the town register of historic places. Properties may only be registered with the owner’s consent. Members of the historic preservation commission or the commission as a whole may generate nominations. In its designation decision, the commission shall consider the Concrete historic inventory and the town comprehensive plan.
(b) 
In the case of individual properties, the designation shall include the UTM reference and all features – interior and exterior – and outbuildings that contribute to its designation.
(c) 
The historic preservation commission shall consider the merits of the nomination, according to the criteria in subsection (1) of this section and according to the nomination review standards established in rules at a public meeting.
Adequate notice will be given to the public, the owner(s) and the authors of the nomination, if different, and lessees, if any, of the subject property prior to the public meeting according to standards for public meetings established in rules and in compliance with Chapter 42.30 RCW, Open Public Meetings Act. Such notice shall include publication in a newspaper of general circulation in the Concrete area and posting on the property. If the commission finds that the nominated property is eligible for the town register of historic places, and secures the owner’s consent, the commission shall make a recommendation to the Concrete town council that the property be listed in the register. The public, property owner(s) and the authors of the nomination, if different, and lessees, if any, shall be notified of the listing.
(d) 
Properties listed on the town register of historic places shall be recorded on official building permit records with an “HR” (for historic register) designation. This designation shall not change or modify the underlying zone classification.
(3) 
Removal of Properties from the Register. In the event that any property is no longer deemed appropriate for designation to the town register of historic places, the commission may initiate removal from such designation by the same procedure as provided for in establishing the designation in subsection (1) of this section. A property may be removed from the town register without the owner’s consent.
(4) 
Effects of Listing on the Register.
(a) 
Listing on the town register of historic places is an honorary designation denoting significant association with the historic, archaeological, architectural, engineering, or cultural heritage of the community. Properties are listed individually.
(b) 
Prior to the commencement of any repair or rehabilitation on a register property, excluding ordinary repair and maintenance and emergency measures defined in CMC § 2.18.070(3)(d), the owner must request and receive a certificate of appropriateness from the commission for the proposed work. Violation of this rule shall be grounds for the commission to review the property for removal from the register.
(c) 
Prior to whole or partial demolition of a register property, the owner must request and receive a waiver of a certification of appropriateness.
(d) 
Once the town is certified as a certified local government (CLG), all properties listed on the town register of historic places may be eligible for a special tax valuation on their rehabilitation (see CMC § 2.18.070).
(Ord. 671 § 1, 2010)
(1) 
Review Required. No person shall change the use, construct any new building or structure, or reconstruct, alter, restore, remodel, repair, move, or demolish any existing property on the town register of historic places without review by the board and without receipt of a certificate of appropriateness, or in the case of demolition, a waiver, as a result of the review.
The review shall apply to all features of the property – interior and exterior – that contribute to its designation and are listed on the nomination form. Information required by the board to review the proposed changes is established in rules.
(2) 
Exemptions. The following activities do not require a certificate of appropriateness or review by the board: ordinary repair and maintenance that include painting or emergency measures defined in CMC § 2.18.030(11).
(3) 
Review Process.
(a) 
Requests for Review and Issuance of a Certification of Appropriateness or Waiver. The building official shall report any application for a permit to work on a designated town register property to the commission. The commission review will occur concurrently with the town permit review process. If the activity is not exempt from review, the commission shall notify the applicant of the review requirements. The building official shall not issue any such permit until a certificate of appropriateness or a waiver is received from the commission, but shall work with the commission in considering building and fire code requirements. Life safety codes must be maintained.
(b) 
Commission Review. The owner or his/her agent (architect, contractor, lessee, etc.) shall apply to the commission for a review of proposed changes on a town register property and request a certificate of appropriateness or, in the case of demolition, a waiver. Each application for review of proposed changes shall be accomplished by such information as is required by the board established in its rules for the proper review of the proposed project.
The commission shall meet with the applicant and review the proposed work according to the design review criteria established in rules. Unless legally required, there shall be no notice, posting, or publication requirements for action on the application, but all such actions shall be made at regular meetings of the commission.
The commission shall complete its review and make its recommendations within 30 days of the date of receipt of the application. If the commission is unable to process the request, the commission may request an extension of time. The commission’s recommendations shall be in writing and shall state the findings of fact and reasons relied upon in reaching its decision. Any conditions agreed to by the applicant in this review process shall become conditions of approval of the permits granted if the owner agrees to the commission’s recommendations.
The commission, according to the standards established in the commission’s rules, shall award a certificate of appropriateness. The commission’s recommendations and, if awarded, the certificate of appropriateness shall be transmitted to the building or zoning official. If a certificate of appropriateness is awarded, the building or zoning official may then issue the permit.
(c) 
Demolition. A waiver of the certificate of appropriateness is required before a permit may be issued to allow whole or partial demolition of a designated town register property. The owner or his/her agent shall apply to the commission for a review of the proposed demolition and request a waiver. The applicant may meet with the board in an attempt to find alternatives to demolition. These negotiations may last no longer than 45 days from the initial meeting of the commission, unless either party requests an extension. If no request for an extension is made and no alternatives to demolition have been agreed to, the commission shall act and advise the official in charge of issuing a demolition permit of the approval or denial of the waiver of a certificate of appropriateness. Conditions in the case of granting a demolition permit may include allowing the commission up to 45 additional days to develop alternatives to demolition. Any conditions agreed to by the applicant in this review process shall become conditions of approval of the permit granted. After the property is demolished, the commission shall initiate removal of the property from the register.
(d) 
Appeal of Approval or Denial of a Waiver of a Certificate of Appropriateness. The board’s decision regarding a waiver of a certificate of appropriateness may be appealed to the town council within 10 days. The appeal must state the ground upon which the appeal is based. The appeal shall be reviewed by the town council with comments to council presented by at least one commission member and the appellant(s), in addition to all records pertaining to appeal. Owner retains the option, after council appeal, to remove property from the register. Appeal of the town council’s decision regarding a waiver of a certificate of appropriateness may be appealed to superior court.

The property is included within a class of historic properties determined eligible for special valuation by the town under CMC § 2.18.050;
(iii) 
The property has been rehabilitated at a cost which meets the definition set forth in RCW 84.26.020(2) and identified in CMC § 2.18.030 within 24 months prior to the date of application; and

(d) 
Rehabilitation and Maintenance Criteria. The Washington State Advisory Council’s Standards for Rehabilitation and Maintenance of Historic Properties, also known as the Secretary of the Interior’s Standards for Rehabilitation.
The following rehabilitation and maintenance standards shall be used by the board as minimum requirements for determining whether or not a historic property is eligible for special valuation and whether or not the property continues to be eligible for special valuation once it has been so classified:
(i) 
Standards of Rehabilitation for Special Valuation.
(A) 
Every reasonable effort shall be made to provide compatible use for a historic property that requires minimal alteration of the building, structure, or site and its environment, or to use a historic property for its original intended purpose.
(B) 
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.
(C) 
All building, structures and sites shall be recognized as products of their own time. Alterations that have no historical basis and which seek to create an earlier appearance shall be discouraged.
(D) 
Changes that 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. These changes may have acquired significance in their own right and this significance shall be recognized and respected.
(E) 
Distinctive stylistic features or examples of skilled craftsmanship that characterize a building, structure or site shall be treated with sensitivity.
(F) 
Deteriorated architectural features shall be repaired rather than replaced, whenever possible. In the event replacement is necessary, the new material should match the material being replaced in composition, design, color, texture and other visual qualities. Repair or replacement of missing architectural features should be based on accurate duplication of features, substantiated by historical, physical or pictorial evidence rather than on conjectural designs or the availability of different architectural elements from other building or structures.
(G) 
The surface cleaning of structure shall be undertaken with the gentlest means possible. Sandblasting and other cleaning methods that will damage the historic building materials shall not be undertaken.
(H) 
Every reasonable effort shall be made to protect and preserve archaeological resources affected by, or adjacent to, any project.
(I) 
Contemporary design for alterations and additions to existing properties shall not be discouraged when alterations and additions do not destroy significant historical, architectural or cultural material, and such design is compatible with the size, scale, color, material and character of the property, neighborhood or environment.
