A. 
Scope and applicability.
This section sets forth provisions for review of demolition permits that affect structures that are 125 years of age or greater at the time of permit application, and that involve demolition of 4,000 gross square feet or more on a parcel, or are located within designated Mixed Use Centers, or are properties listed on the National Register of Historic Places either as part of a district or individually listed. The following project types are exempt from this section:
1. 
Demolition of single-unit dwellings that are not located within National Register Historic Districts or listed on the National Register of Historic Places;
2. 
Demolitions of buildings that are less than 4,000 square feet in size that are not located within National Register Historic Districts or listed on the National Register of Historic Places, or located within Mixed Use Centers.
3. 
Demolitions of structures that are owned by a religious organization and used for church purposes as defined by Washington State WAC 458-16-190.
B. 
Demolitions affecting designated City Landmarks. All demolition permits affecting City Landmarks (either individually listed or within local historic special review districts) shall be reviewed pursuant to procedures outlined in TMC § 13.05.040E and TMC § 13.07.110.
C. 
The provisions of this chapter are not intended to be duplicative of other related cultural resource or historic review processes, including those mandated by Section 106 of the National Historic Preservation Act, National Environmental Policy Act or other applicable review processes.
D. 
Projects involving locations where a Subarea Plan and a companion area-wide, non-project Environmental Impact Statement (“EIS”) have been completed, including the Downtown Tacoma Regional Growth Center, the Tacoma Mall Neighborhood Regional Growth Center and the Tideflats Subarea; projects involving areas subject to City of Tacoma Shoreline jurisdiction as defined in Title 19 Shoreline Master Program; and projects involving sites within Urban Residential (UR) districts where the City has completed an area-wide, non-project Environmental Impact Statement to raise the residential threshold exemption to 40 units, and where the proposal exceeds 20 units, shall be reviewed under the provisions of TMC Chapter 13.13 Archaeological, Cultural and Historic Resources Protection.
E. 
Requirements. Applications for a demolition permit shall include a demolition summary report that identifies all affected structures that are 125 years of age or greater, and shall note any such structures that are listed on the National Register of Historic Places either individually or as part of a district. Submittal materials shall include at minimum:
1. 
Current photographs of all elevations of all affected structures; and
2. 
Historical photographs of the affected structures, if available from public sources; and
3. 
Narrative description of the proposed project; and
4. 
Narrative of any known history of affected structures (construction date, architect, builder, occupants, associated events); and
5. 
A narrative statement that evaluates the historical or cultural significance of the property in terms of the Designation Criteria listed in TMC § 13.07.050; and,
6. 
A narrative statement that assesses the physical characteristics of the property, including condition and an architectural description.
7. 
A pre-existing historical survey form or document, such as a Washington State Historic Property Inventory Form, may be submitted to satisfy items d-f above, if the required information is addressed in the survey document.
F. 
The summary demolition report shall be reviewed by the Historic Preservation Officer to determine whether the affected structures appear to be historically significant and should be referred to the Landmarks Preservation Commission for consideration of designation to the Tacoma Register of Historic Places. The Historic Preservation Officer may consider the summary demolition report for up to 30 days.
1. 
Demolition affecting properties under 125 years of age that are listed on the National Register of Historic Places, either individually or as a contributing structure within a historic district, shall be referred to the Landmarks Commission for consideration of mitigation as described in Section 7 below, unless it is determined by the Historic Preservation Officer that such properties lack historic integrity of location, place, setting, materials, association or feeling to the extent that such properties would be unlikely to be eligible for designation to the Tacoma Register.
2. 
Demolition of all other properties shall be preliminarily assessed by the Historic Preservation Officer based upon the criteria for designation of a landmarks TMC § 13.07.040.
G. 
If the Historic Preservation Officer determines that the affected structures possess historic integrity of location, design, setting, materials, workmanship, feeling, and association and are likely eligible for listing on the Tacoma Register of Historic Places, or if the affected properties are already listed on the National Register of Historic Places, the applicant shall be directed to provide a feasibility analysis that includes potential alternative approaches and/or mitigation strategies. The analysis should include whether alternatives that would reduce impacts to historic resources have been considered to mitigate potential impacts, and may contain mitigation proposals for the Commission’s consideration. Mitigation should be proportional to the anticipated impact and historic importance of the subject property, and could include:
•
Avoidance of the historic or cultural resource.
•
Retention of all or some of the historic structure in the new development.
•
Voluntary design review for the new structure to ensure compatibility of the new structure into its surrounding context.
•
Additional documentation of the historic property, such as completing an intensive level Washington State historic property inventory form (HPI).
•
On site interpretation, such as display panels.
•
Commissioning of online interpretive materials, such as a local history website, or other offsite interpretive measures.
•
Architectural salvage/deconstruction of reusable or significant architectural elements and building materials from the site.
•
Relocation of the historic structures to be demolished.
•
Contributing funds to another historic site restoration, documentation or survey effort.
H. 
The demolition summary report and feasibility analysis shall be forwarded to the Landmarks Preservation Commission for its review. When considering its recommendation, the Commission shall weigh the balance of the public benefit of protecting the subject property against the potential impacts to the development project, and to consider alternatives and mitigations proposed in making the determination as to whether a property should be historically designated.
I. 
If the Commission determines that the proposed mitigation is appropriate by a quorum vote, the mitigation proposal shall be recorded as a condition of the demolition permit.
J. 
If the Commission finds that the affected properties over 125 years of age should be included in the Tacoma Register of Historic Places, the Commission shall schedule a public hearing as soon as it is practical to solicit public comment on the potential designation, per the procedural requirements at TMC § 13.07.050.
K. 
During the demolition review process, all requirements of TMC § 13.05.040C relating to the alteration of historic properties apply to the affected properties. If the demolition permit application is withdrawn, but the Commission or City Council is considering historic designation of the subject property, the historic designation review will continue regardless of the demolition permit status.
