The provisions of this Chapter shall be known as the S-20 Historic Preservation District Combining Zone Regulations. The Historic Preservation District Combining (S-20) Zone is intended to preserve and enhance the cultural, educational, aesthetic, environmental, and economic value of structures, other physical facilities, sites, and areas of special importance due to historical association, basic architectural merit, the embodiment of a style or special type of construction, or other special character, interest, or value, and is typically appropriate to selected older locations in the city. The S-20 Zone is similar to the S-7 Preservation Combining Zone, but is designed for larger areas, often with a large number of residential properties that may not be individually eligible for landmark designation but which as a whole constitute a historic district. The S-20 Zone provides generally more expeditious review procedures than those provided in the S-7 Zone. These regulations shall apply in the S-20 Zone, and are supplementary to the provisions of Section 17.136.070 for designated landmarks and to the other regulations applying in the zones with which the S-20 Zone is combined; if a property is both a landmark and located in the S-20 Zone and is therefore subject to both landmark and S-20 regulations, the stricter regulations prevail.

(Ord. No. 13357, § 3(Exh. A), 2-16-2016; Ord. No. 12999, § 4(Exh. A), 3-16-2010; Ord. No. 12899 § 4, Exh. A, 2008; Ord. 12872 § 4, Exh. A (part), 2008; Ord. 12776 § 3, Exh. A (part), 2006: Ord. 12513 Attach. A (part), 2003)

The S-20 Zone may be combined with any other zone.

(Ord. No. 13357, § 3(Exh. A), 2-16-2016; Ord. No. 12899 § 4, Exh. A, 2008; Ord. 12872 § 4, Exh. A (part), 2008; Ord. 12776 § 3, Exh. A (part), 2006: Ord. 12513 Attach. A (part), 2003)

A.

Except for projects that are exempt from design review as set forth in Section 17.136.025, no Building Facility (see Section 17.09.040 for definition), Designated Historic Property, Potentially Designated Historic Property, Telecommunications Facility, Sign, or other associated structure shall be constructed, established, or altered in exterior appearance, unless plans for the proposal have been approved pursuant to the design review procedure in Chapter 17.136, and when applicable, the additional provisions in Sections 17.100B.050, 17.100B.060, and 17.100B.070, the Telecommunications regulations in Chapter 17.128, or the Sign regulations in Chapter 17.104.

B.

See Section 17.136.075 for design review criteria for the demolition or removal of Designated Historic Properties and Potentially Designated Historic Properties.

C.

Landmarks Referral. If an application is for regular design review in the S-20 Zone, and the Director of City Planning determines that a proposed addition or alteration will have a significant effect on the property's character-defining elements that are visible from a street or other public area, the Director may, at his or her discretion, refer the project to the Landmarks Preservation Advisory Board for its recommendations. "Character-defining elements" are those features of design, materials, workmanship, setting, location, and association that identify a property as representative of its period and contribute to its visual distinction or historical significance. An addition or alteration is normally considered "visible from a street or other public area" if it affects a street face or public face of the facility or is otherwise located within the "critical design area," defined as the area within forty (40) feet of any street line, public alley, public path, park or other public area.

(Ord. No. 13357, § 3(Exh. A), 2-16-2016; Ord. No. 13172, § 3(Exh. A), 7-2-2013; Ord. No. 13064, § 2(Exh. A), 3-15-2011; Ord. No. 13028, § 2(Exh. A), 7-20-2010; Ord. No. 12899 § 4, Exh. A, 2008; Ord. 12872 § 4, Exh. A (part), 2008; Ord. 12776 § 3, Exh. A (part), 2006: Ord. 12513 Attach. A (part), 2003)

In the S-20 Zone, proposals requiring Regular design review approval pursuant to Section 17.100B.030 may be granted only upon determination that the proposal conforms to the Regular design review criteria set forth in the design review procedure in Chapter 17.136 and to all of the following additional criteria:

A.

That the proposal will not substantially impair the visual, architectural, or historic value of the affected site or facility. Consideration shall be given to design, form, scale, color, materials, texture, lighting, detailing and ornamentation, landscaping, signs, and any other relevant design element or effect, and, where applicable, the relation of the above to the original design of the affected facility.

B.

That the proposed development will not substantially impair the visual, architectural, or historic value of the total setting or character of the S-20 Historic Preservation Zone or of neighboring facilities. Consideration shall be given to the desired overall character of any such area or grouping of facilities, including all design elements or effects specified in Subsection (A) above; and

C.

That the proposal conforms with the Design Guidelines for Landmarks and Preservation Districts as adopted by the City Planning Commission and, as applicable for certain federally-related projects, with the Secretary of the Interior's Standards for the Treatment of Historic Properties.

(Ord. No. 13357, § 3(Exh. A), 2-16-2016; Ord. No. 12899 § 4, Exh. A, 2008; Ord. 12872 § 4, Exh. A (part), 2008; Ord. 12776 § 3, Exh. A (part), 2006: Ord. 12513 Attach. A (part), 2003)

Editor's note— Ord. No. 13028, § 2(Exh. A), adopted July 20, 2010, repealed the former Sections 17.100B.060 and 17.100B.070 in their entirety, which pertained to the criteria for demolition or removal, and postponement of demolition or removal, respectively, and derived from Ord. No. 12513, Att. A(part), adopted in 2003; Ord. No. 12776, Exh. A (part), adopted in 2006; Ord. No. 12872, § 4, Exh. A (part), adopted in 2008; Ord. No. 12899, § 4, Exh. A, adopted in 2008.

Except as otherwise authorized under Sections 17.100B.030 and 17.100B.070, the owner, lessee, or other person in actual charge of each structure in the S-20 Zone shall keep in good repair all of the exterior, as well as all interior portions whose maintenance is necessary to prevent deterioration and decay of the exterior.
