Page 2 DocuSign Envelope ID:456423A1-4D27-4189-BE1E-F655342315F8 Attachment A September 5,2023 312 Liberty St., Storey Residence Expansion NOW, THEREFORE,BE IT RESOLVED THAT: A. The foregoing recitals are true and correct and incorporated herein by reference. B. Based on the staff report, staff presentation, comments received, and the public hearing, the Historic and Cultural Preservation Committee makes the following findings based on substantial evidence in the record: California Environmental Quality Act 1. The City of Petaluma, acting as the Lead Agency, has conducted environmental review in compliance with CEQA Guidelines Section 15061 (Review for Exemption) for the proposed project. Based on the findings of this review, staff concludes that the project qualifies for a categorical exemption pursuant to Section 15301 (Class 1 — Existing Facilities)for modifications to existing structures,including minor additions and remodels, provided that the project involves negligible or no expansion of existing or former use. As proposed, the project involves a minor addition to an existing single-family residence and will be retained as a single-family residence as a result of the project and, as such, qualifies for the Class I categorical exemption. The project is also categorically exempt under Section 15331 (Class 31 — Historical Resource Restoration/Rehabilitation) of the CEQA Guidelines, which includes modifications to historic structures that are consistent with the Secretary of the Interior's Standards for Rehabilitation. The analysis provided finds that, as proposed and conditioned, the project is consistent with the Oakhill-Brewster Historic District Preservation Guidelines and Standards and the Secretary of the Interior Guidelines for Treatment of Historic Properties. As such, the project qualifies for a Class 31 categorical exemption for restoration/rehabilitation of a historical resource in that the project is limited to the repair and rehabilitation of historical resources in a manner consistent with the Secretary of the Interior's Standards for the Treatment of Historic Properties with Guidelines for Preserving, Rehabilitation, Restoring, and Reconstructing Historic Buildings (1995), Weeks and Grimmer. If a project qualifies for the use of a categorical exemption, then the lead agency must determine whether the project is subject to any of the exceptions to the use of a categorical exemption, pursuant to CEQA Guidelines Section 15300.2. None of the exceptions to the use of a categorical exemption apply as (a) the project is not located in an area where it may impact an environmental resource of hazardous or critical concern; (b)will not result in cumulative impacts; (c) does not involve an activity where there is a reasonable possibility that the activity will have a significant effect on the environment due to unusual circumstances; (d)will not result in damage to scenic resources within a highway officially designated as a state scenic highway; (e) is not located on a hazardous waste site pursuant to Section 65962.5 of the Government Code, and(f)will not result in a substantial adverse change in the significance of a historical resource. As none of the exceptions to the exemption apply,the project would not be precluded from the use of the Class 1 and Class 31 categorical exemptions. Therefore, no further environmental analysis is needed. Petaluma General Plan 2. The Project is consistent with the site's Medium Density Residential designation in the Page 3 DocuSign Envelope ID:456423A1-4D27-4189-BE1E-F655342315F8 Attachment A September 5,2023 312 Liberty St., Storey Residence Expansion General Plan Land Use Map in that the site is developed for single-family housing as is intended by the land use designation. 3. The project is, for the reasons contained in the September 5, 2023, Historic and Cultural Preservation Committee staff report, consistent with the following General Plan policies: Policy 1-P-3 Preserve the overall scale and character of established residential neighborhoods. Policy 3-P-1 Protect historic and archaeological resources for the aesthetic, cultural, educational, environmental, economic, and scientific contribution they make to maintaining and enhancing Petaluma's character, identity and quality of life. Historic Demolition Resolution No. 2017-122 4. The proposed demolition work to be completed at the rear of the dwelling to support the rear expansion includes the removal of the existing ground floor addition and its shed roofs, which are less than 50 percent of the subject property's exterior building walls. Additionally, the project does not alter the maximum height of the building and continues to support its existing rear ridgeline. For these reasons, the project has not been defined as a demolition consistent with Resolution No. 2017-122. Oakhill-Brewster Historic District Preservation Guidelines and Standards 5. Architectural - Style, Design, Arrangement, Texture, Materials, and Color a. Style. The Shingle and Eclectic Period Revival architectural styles are 2 of 16 styles appearing in the Historic District. The project extends and applies the dwelling's transitional architectural style of Shingle and Eclectic Period Revival. New roofing material, exterior horizontal siding of aluminum bevel siding, and window types are proposed to match the existing features of the building. The project does not alter the front elevation, apart from the repair of the front porch deck; therefore, the dwelling's original detailing is preserved. As such, the project is consistent with this district guideline. b. Design. The project involves a two-story, 314-square-foot rear extension to increase the habitable space on the first and second floors and extension of the gable roof with the addition of 2 new shed roofs. The existing one-story rear addition with shed roofs was not original to the building and was added at a later date. They do not contain elaborate architectural details. The building footprint is slightly adjusted for the new two-story expansion; however, it does not alter the building's orientation and general form and does remain consistent with the building's front fagade in terms of scale, materials, and design motifs. As such, the project is consistent with this district guideline. 6. Arrangement a. Setback.No expansion of the front elevation is proposed. The proposed rear addition is within the required setbacks and would not modify or introduce new architectural Page 4 DocuSign Envelope ID:456423A1-4D27-4189-BE1E-F655342315F8 Attachment A September 5,2023 312 Liberty St., Storey Residence Expansion features visible from the public right-of-way that would impact or alter the building's current setbacks or character. As such, the project is consistent with this guideline. b. Side Yards.The project does not propose expansion of existing front or side elevations. Similar to other properties within the Oakhill-Brewster Historic District and properties facing Liberty Street,this building has a small front yard with driveway access and side yards similar in proportion to those of the immediate neighborhood. The rear addition does not alter the site's existing South side yard. As such,the project is consistent with this district guideline. c. Height. The project does not increase the residence's overall height. The building currently contains two prominent gable roof ridgelines and small dormers. The rear expansion extends the ridgeline perpendicular to Liberty Street and does not introduce any increase to the existing height of the building. As such, the project is consistent with this district guideline. d. Roofline.Residences within the immediate neighborhood include gable, hip, and shed roof forms across a variety of architectural styles,including the adjacent Craftsman and Queen Ann architectural style.The proposed rear addition extends one of the prominent gable roof ridgelines, the gable roof pitch, and the eave line but does not increase the height of the building. A previous addition included the one-story rear addition with shed roofs.Residences within the immediate neighborhood include gable,hip, and shed roof forms across a variety of architectural styles,including the adjacent Craftsman and Queen Ann architectural style. The dwelling's existing prominent rooflines continue to establish its height, and its secondary rooflines are lower in height and are not visually prominent from the public right-of-way. As such, the project is consistent with this district guideline. e. Facade.The proposed project does not alter the appearance or architectural style of the building's front fagade. The rear expansion extends one of the building's prominent ridgeline, gable roof, eave line, height, siding, and trim. Each feature continues and coordinates with the building's Shingle and Eclectic Period Revival architectural style. Relocated and new windows align at a continuous horizontal datum line across the North, South, and East facades. New windows are not equally spaced to indicate a consecutive rhythm;however,they are placed in balanced locations reducing solid wall area and providing natural lighting to various living spaces on the ground and second floor. As such, the project is consistent with this district guideline. 7. Texture and Materials.The project proposes materials that are consistent with the original transitional style of the Shingle and the Eclectic Period Revival of the residence. Proposed materials include new composition shingle roofing and aluminum bevel siding to match existing materials. No new material types are introduced to the building or its rear expansion. As such, the project is consistent with this district guideline. 8. Color.The building's exterior,including its siding and trims,is currently painted in a light blue color. The project includes the building's rear expansion, front porch deck repair, and its associated architectural features to be painted to match its existing surfaces after Page 5 DocuSign Envelope ID:456423A1-4D27-4189-BE1E-F655342315F8 Attachment A September 5,2023 312 Liberty St., Storey Residence Expansion construction. The new composite shingle roofing is to match the existing roofing material and color. The colors and materials for the rear expansion would remain consistent with the existing building and are appropriate for its transitional Shingle and Eclectic Period Revival architectural style. As such, the project is consistent with this district guideline. 9. Accessory Fixtures. The architectural drawing set does not include nor indicate additional accessory fixtures to the building which are additional details that may enhance the design and entrances to a residential building. It is recommended that appropriate lighting fixtures are considered for a cohesive lighting scheme since the project includes the alteration of its rear entrance. Draft Resolution COA #15 provides for administrative review of future lighting fixtures consistent with the historic district's design guidelines and the Secretary of the Interior's Standards for the Treatment of Historic Buildings. As such, the project is consistent with this district guideline. 10. Landscape a. Fencing. No new landscape fencing, walls, and screening are a part of the proposed project, and none are required to construct the proposed modifications successfully. As such, the project is consistent with this district guideline. b. Plantings.No exterior landscaping or hardscape work,noting plantings nor paving,are included in the project or indicated in the proposed architectural drawings, and none are required by the proposed modifications. Draft Resolution COA #16 provides for administrative review of future minor landscape work if desired by the property owners. As such, the project is consistent with this guideline. c. Paving.No exterior landscaping, hardscape work, plantings, or paving are included in the project or indicated in the proposed architectural drawings. Draft Resolution COA #16 provides for administrative review of future minor landscape work if desired by the property owners. As such, the project is consistent with this guideline. 11. Public Access Easement and Dedication on Alleys. The site does not abut a publicly accessible alley. Therefore, this district guideline is not applicable. 12. Signs. The site is located in a residential zone (R3) and is used as a residential building. No signage is proposed. Therefore, this district guideline for signage is not applicable. Secretary of the Interior's Standards for the Treatment of Historic Properties 13. The Project is consistent with the Secretary of the Interior's Standards for the Treatment of Historic Properties for Rehabilitation, as follows: a. Standard #1: The building is located in a residentially zoned neighborhood and was constructed for residential use and has been historically used for residential purposes. The proposed modifications are intended to rehabilitate the building in order to create a more cohesive, efficient, and accommodating residence. No changes are proposed to the use of the building as a single-family residence. As such, the project is consistent Page 6 DocuSign Envelope ID:456423A1-4D27-4189-BE1E-F655342315F8 Attachment A September 5,2023 312 Liberty St., Storey Residence Expansion with this standard. b. Standard #2: The project does not propose the removal of integral historic architectural features related to "Shingle" and "Eclectic Period Revival" architectural styles. The project does not alter or replace original features from the "core"building; however, it does include a rear expansion and front porch decking and stair repair. The proposed work and designs for these alterations do not impact the building's historic character since the rear extension is compatible in design and materials to the dwelling. As such, the project is consistent with this standard. c. Standard #3: The project does not create a false sense of historical development and does not add conjectural features or architectural elements from other buildings to the "core"building's original Shingle and Eclectic Period Revival architectural styles. The proposed scope provides for a two-story rear expansion, front porch deck repair, new windows, and removal of an existing chimney to facilitate and optimize the expansion of a residential building. As such, the project is consistent with this guideline. d. Standard #4: As noted in the previous historical context section, the dwelling continues to be located in Liberty Street, an area currently designated as the Oakhill- Brewster Historic District. The building has also experienced remodeling with exterior additions and minor alterations. Through the relocation and additions, the building has continued to uphold the building's original Single and Eclectic Period Revival architectural style. As determined from the survey photographs provided with the application materials and by an on-site visit, the building and its current site have experienced changes since its original construction,and additional historic significance has not been acquired. As such, the project is consistent with this guideline. e. Standard#5: As previously stated,the project will preserve the building's Shingle and Eclectic Period Revival architectural features and continue its existing exterior finishes to the rear addition and side rear porch enclosure to include roofing, siding, and trim to match existing. As such, the project is consistent with this standard. f. Standard #6: The project includes the installation of a new asphalt shingle roof and horizontal siding for the rear expansion,along with the removal of an existing chimney. The chimney cap visible from the exterior is a prefabricated and lightweight metal cylinder and is not original to the dwelling or compatible with the dwelling's architectural styles. As such, the project is consistent with this guideline. g. Standard #7: The project description and its architectural drawing set do not indicate the use of chemical or physical treatments to the historic building. Draft Resolution COA #13 requires that chemical or physical treatments, if appropriate, will be undertaken using the gentlest means possible to avoid damage to the historic materials. h. Standard #8: Some excavation is likely to occur as part of the rear addition and rear side porch. However, these areas on the site have already experienced disturbance during the building's relocation and later additions. Work of undisturbed ground is not a part of this project, and a condition is included as a preventative measure to protect Page 7 DocuSign Envelope ID:456423A1-4D27-4189-BE1E-F655342315F8 Attachment A September 5,2023 312 Liberty St., Storey Residence Expansion and preserve significant archeological resources if potentially significant prehistoric or historic archeological resources are encountered during the course of ground-disturbing activities (refer to Draft Resolution COA#14). As such, the project is consistent with this standard. i. Standard#9: As previously noted in the previous section for evaluation of the historic district's "design" guideline, the proposed project removes the existing one-story rear addition and shed roofs to incorporate a cohesive two-story rear expansion, which organizes its interior spaces on the ground and second floor to maximize its residential use and provide habitable spaces. The rear expansion continues one of the existing prominent ridgelines, is not differentiated in height though maintains a cohesive height and does not introduce new architectural features. Most importantly, the new work is compatible with the building's massing, size, scale, and architectural features and does not impact the building's historic integrity. As such, the project is consistent with this standard. j. Standard #10: The proposed project removes the existing one-story rear addition and its shed roofs to incorporate a cohesive two-story rear expansion, which organizes its interior spaces on the ground and second floor to maximize its residential use. The rear addition continues one of the prominent ridgelines of the dwelling and can be removed in the future without impairing the core building's essential form and integrity.As such, the project is substantially consistent with this standard. Implementing Zoning Ordinance 14. The project complies with Residential 3 (R3) discretionary entitlement requirements for development in a historic district in that a required Major HSPAR application for exterior alterations to a historic structure was submitted on October 4, 2022. The proposed project is subject to the objective development standards contained in Table 4.3 of the IZO. The proposed project complies with zoning district-specific development standards, including setbacks, height, and lot coverage, with conditions as described in the draft HSPAR Resolution (Exhibit A). 15. The project is consistent with Chapter 15 (Preservation of the Cultural and Historic Environment) in that it has been reviewed by the HCPC in accordance with the requirements contained in Section 15.070 of the IZO, and it has been determined that the proposed alterations will not adversely affect the character or the historical, architectural, or aesthetic interest or value of the district. 16. As required by Section 15.050 of the IZO, the project is also subject to the Site Plan and Architectural Review (SPAR) findings as required by IZO Section 24.050(E). Given the specificity of the Secretary of the Interior's Standards and the Oakhill-Brewster Historic District Preservation Guidelines and Standards, consistency with these standards is also sufficient to make required SPAR findings.
