SITE DATA Applicant Cynthia Becker Representative John J. Bellisario, LEED AP Submittal Date February 4, 2015 Complete Date June 6, 2015 General Plan Medium High Density Residential Zoning R-3-H (Medium-High Density Residential with Historic Overlay) Site Area 7,044 square feet Historic Status Contributing List Resource Environmental Status Categorically Exempt (CEQA Guidelines §15303: New Construction of Small Structures) SUMMARY The applicant has submitted an application for architectural review of a new two-story accessory structure proposed to be built behind an existing residence at 1005 Islay Street. The structure contains a two-car garage on the ground level and storage space on the second level. The property is developed with a Contributing List Resource in the Old Town Historic District. COMMITTEE’S PURVIEW The Committee’s role is to provide a recommendation to the Community Development Director Meeting Date: September 28, 2015 Item Number: 2 CHC2 - 1 ARCH-0896-2015 (1005 Islay) Page 2 on the application of historic preservation standards and guidelines.1 PROJECT INFORMATION Site Information Table 1: Site Information The site is located at the southeast corner of Osos and Islay Streets, in the Old Town Historic District. The project site is level, just over 7,000 square feet in area, and developed with the Contributing Historic Lauritzen House, estimated to have been built in 1899. The surrounding neighborhood is characterized by single-family residences with historical character. At least 15 Contributing Historic Resources are located on the 1000 block of Islay Street, and neighboring properties along Osos Street (1541, 1542, and 1609 Osos) are also Contributing List Resources. Single-story residences in a Neo-Classical Rowhouse style predominate on Islay. At the corner with Osos are two examples of residences in a Plains Cottage style. . West and south of the site on Osos Street are commercial buildings and an apartment building, exhibiting a mixture of styles transitioning to the Railroad Historic District. Businesses in this area include Faces a la Mode Spa and Salon, Kyle Roofing, and Gus’s Grocery. 1 Historic Preservation Ordinance § 14.01.030(B)(4) and (B)(5)) Access Osos Street Site Dimensions (approx.) Area: 7,044 square feet; Width: 50 feet; Depth: min. 140 ft., max. 170 ft. Street Frontage: 50 feet (Islay) Topography Slope: Flat Natural Features: Several small trees and one large White Oak tree on site, all to be retained; Adjacent to Fixlini-Lizzi Creek Present Use & Development Single-family residence (3-BR); Dilapidated accessory structure in rear yard Surrounding Use / Zoning Single-family dwellings (R-2-H) and (R-3-H) Commercial and Multiple-Family Residential (R-3-H) and (C-N-H) Figure 1: Historical residences in vicinity CHC2 - 2 ARCH-0896-2015 (1005 Islay) Page 3 A tall fence surrounds the rear portion of the site, and a driveway provides access to the site from Osos Street through a gate in the fence (though the condition of the site suggests that this access has not been in regular use within the recent past). This part of the sidewalk has granite curbing, and the City’s Engineering Standards call for the retention of unique or historical sidewalk features (see Condition of Approval #5). Fixlini-Lizzi creek runs through an underground culvert from under Osos Street and behind the property, to the south. There are no heritage trees on the site. One large White Oak tree will be retained along with all other smaller trees and tree clusters on the site. No trees are proposed to be removed. Project Description The project consists of the construction of a two-story accessory structure: a 2-car garage with 437 square feet of accessory space above, to be used as an artist’s workspace. A small existing wood-sided accessory structure currently located behind the main residence will be demolished. The access driveway will be improved and new pervious paving installed. A turnaround area will be provided to allow vehicles to exit the site in a forward direction. Any approval should be subject to the protection of granite curbing adjacent to the project (see draft resolution, condition #5). Two new street trees will be planted along the Osos Street frontage. No modifications will be made to remainder of the site or the existing residence. EVALUATION Evaluation of this project is focused on determining whether the new accessory structure is consistent with the Historic Preservation Guidelines and the Secretary of the Interior’s Standards for the Treatment of Historic Properties (“Secretary of the Interior’s Standards”). This project is located in the Old Town Historic District, one of the City’s oldest residential neighborhoods, built up historically around the turn of the 20th Century. Common site features Figure 2: 1005 Islay Figure 3: Proposed accessory structure CHC2 - 3 ARCH-0896-2015 (1005 Islay) Page 4 and architectural characteristics within the district are summarized in Table 2.2 Projects involving new construction in historic districts should be architecturally compatible with the historical character of the district; should not detract from historically designated structures adjacent to the property; and, accessory structures and additions on properties with historic resources should complement the primary structure’s historic character. 3 Table 2: Old Town Historic District Site Features and Characteristics Predominant Architectural Features Prominent street yard setbacks of 20 ft. or more Coach barn (garage) recessed into rear yard Finish floors raised 2-3 feet above finish grade Front building facades oriented parallel to street Front entries oriented toward street, with prominent walk, stairs and porch Two- and rarely three-story houses Mostly gable and hip roof types Highly ornamented roof features, including prominent fascias, bargeboards, gable end treatments, decorative shingles, prominent pediments or cornices Traditional fenestration, such as double-hung, wood sash windows, divided light windows, ornamental front doors, wood screen doors Painted wood surface material, including siding and decorative moldings Historic Preservation Guidelines Residence style, siting, and detail. The primary residence on the site is a single-story house on a raised foundation, in a “workingman’s Queen Anne Cottage” style, sheathed in wood shiplap siding, and with a vertical wood board skirt around the base.4 It has a steeply pitched multi- hipped, multi-gabled roof of composition shingles. Rectangular windows are grouped in pairs along the Osos frontage. At the rear of the residence is a rectangular flat-roofed building section, of the same exterior siding, but with a seam line that gives the appearance of a later addition. The building is set back 2 Historic Preservation Program Guidelines § 5.2.1 3 Historic Preservation Program Guidelines § § 3.2.1, 3.2.2, 3.4.1(c) 4 Description provided in the historical property information file (“yellow file”) for 1005 Islay, maintained by the Community Development Department.

The entry is on Islay Street, through a raised wooden porch with wood railings of turned balusters and decorated above with spindle and spool detail. Staff Analysis: The Historic Preservation Program Guidelines require that new structures be designed to be architecturally compatible with the prevailing historic character of the historic district “as measured by their consistency with the scale, massing, rhythm, signature architectural elements, exterior materials, siting and street yard setbacks of the district’s historic structures,…” (§ 3.2.1) and architecturally compatible with nearby historic resources: New development should not sharply contrast with, significantly block public views of, or visually detract from, the historic architectural character of historically designated structures… (HPPG § 3.2.2) New accessory structures should complement the primary structure’s historic character through compatibility with its form, massing, color, and materials. (HPPG § 3.4.1(c)) The Secretary of the Interior’s Standards for the Treatment of Historic Properties also provide guidance for designing new construction adjacent to historic buildings: New additions, exterior alterations, and related new construction will not destroy historic materials, features, and spatial relationships that characterize the property. The new work shall be differentiated from the old and will be compatible with the historic materials, features, size, scale and proportion, and massing to protect the integrity of the property and its environment. (Standards for Rehabilitation, #9) Scale, form, and siting. As an accessory structure that is six feet shorter than the main residence and less than half of the residence’s building footprint area, the building’s form and scale is in keeping with the primary residence on the site and with other residences and buildings in the vicinity. The new structure is proposed to be located at the rear of the site, behind the primary residence, typical of the coach barn (garage) structures developed during this time period. The location of the addition would not obstruct public views of the primary historic residence. The proposed structure is lower in scale (both in size and height) than the primary residence. A gable roof form is used to minimize the height of the building. It echoes the pitched roof forms of the primary residence but presents a more rectangular building shape to Osos Street. This roofline provides a visual transition from structures along Osos Street, which have flatter roof lines, to the historic residences along Islay with their characteristic pitched rooflines. Materials and architectural elements. The exterior walls are proposed to be sided with Hardie cement-fiber board lap siding (7 ¼”), painted Tahoe Snow, a very light blue-grey color, and accented with a wood “belly-band,” white in color. The texture and appearance of this type of siding is compatible with the light grey shiplap wood siding on the residence. Rectangular windows, “one-over-one” and divided in form, are grouped in a pattern that is harmonious with the pattern of grouped pairs of “one-over-one” and divided windows on the main residence. Wood trim is proposed to be painted to match the treatment on the house. CHC2 - 5 ARCH-0896-2015 (1005 Islay) Page 6 Detailing is restrained, limited to wood fascia board, undecorated roof trim and a “belly band” accenting the exterior between floors. The roofline itself has been lowered by incorporation of dormers so that while its pitch echoes that of the residence, it is lower and less steep than the roof of the residence. No attempt is made to mimic distinctive features of the residence, such as the board skirt, shingle siding, spindle and spool porch decoration. In this way, the accessory structure has been designed to be compatible with, but differentiated from the primary residence so that it does not compete with the character-defining details of the historic house. Existing accessory structure. City records5 acknowledge the presence of “a small detached 1-story structure in the back yard” but do not discuss any accessory building of architectural or historical significance on the property. Older Sanborn Maps indicate that an accessory structure was originally located in the southeast rear corner of the property, but the existing accessory structure is in the middle of the rear yard. The existing building does not appear to be contemporary with the historic residence and lacks decoration or detailing that is characteristic of the style of the residence, and it is in a highly dilapidated condition. Aluminum sliding windows and exterior siding of varying orientation and appearance indicate that it has been extensively modified. Under these circumstances, this structure would not meet criteria used to evaluate architectural or historical significance. Its demolition would not degrade the historical significance of the property, which is derived from the character of the primary residence. ENVIRONMENTAL REVIEW The project is categorically exempt from the provisions of the California Environmental Quality Act (CEQA). It consists of the minor alteration of an existing structure, with addition of less than 10,000 square feet of floor area, as described in CEQA Guidelines § 15301(e)(2) (Existing Facilities). Public services and facilities are available, and the project is not located within an environmentally sensitive area. RECOMMENDATION Based on this evaluation, staff recommends that the Committee adopt the draft resolution recommending that the Director approve this project, based on findings and subject to conditions as described in the resolution. ALTERNATIVES 1. Continue the project with direction to the applicant and staff on pertinent issues. 2. Deny the project based on findings of inconsistency with the General Plan, Historic Preservation Ordinance, or Historic Preservation Program Guidelines. ATTACHMENTS 1. Draft Resolution 2.
