ARCH-0005-2025 (1253 Mill) Construction of a new dwelling on a Contributing List Property in the Mill Street Historic District CULTURAL HERITAGE COMMITTEE AGENDA REPORT SUBJECT: ARCH-0005-2025 (1253 MILL) CONSTRUCTION OF A NEW DWELLING ON A CONTRIBUTING LIST PROPERTY IN THE MILL STREET HISTORIC DISTRICT BY: Walter Oetzell FROM: Brian Leveille Phone Number: (805) 781-7593 Phone Number: (805) 781-7166 Email: woetzell@slocity.org Email: bleveille@slocity.org APPLICANT: Darren Pollard RECOMMENDATION Provide a recommendation to the Community Development Director as to the consistency of the proposed new construction with applicable historical preservation policies, standards, and guidelines. 1.0 BACKGROUND In 1987, the Council established the Cultural Heritage Committee as a. permanent advisory body, created three Historical Preservation Districts , and adopted Historic Preservation Program Guidelines.1 The Historic Preservation Ordinance (Municipal Code Ch. 14.01) was adopted in 2010,2 to review and guide development applications that have the potential to affect historic resources. New construction located in historic districts or on historically listed properties is subject to review and recommendation by the Cultur al Heritage Committee (SLOMC §14.01.030(C)(4)). The applicant proposes to construct a new single-family dwelling at the rear of the property at 1253 Mill Street (see Project Plans, Attachment A). The property was designated as a Contributing List Property in 1983,3 and is within the Mill Street Historic District. 2.0 DISCUSSION 1 Resolutions 6157 and 6158, adopted February 3, 1987, and Ordinance 1086, adopted February 17, 1987 2 Ordinance 1557, adopted December 7, 2010 3 Resolution 5197, adopted August 16, 1983 Meeting Date: 2/24/2025 Item Number: 4a Time Estimate: 30 mins Figure 1: 1253 Mill Street Page 9 of 34 Item 4a ARCH-0005-2025 (1253 Mill) Cultural Heritage Committee Report – February 24, 2025 2.1 Site and Setting The property is on the south side of Mill Street, about 120 feet west of Johnson Avenue, in a Medium Density Residential (R-2) Zone characterized by single family dwellings. It is in the Mill Street Historic District and is a Contributing List Property within the district. The District developed at the turn of the 20th century, with most existing buildings dating from the 1900s to 1920s. The characteristic elements of the Mill Street Historic District are described in the City’s Historic Preservation Program Guidelines (Attachment B). The site is developed with a small single-family dwelling, built in 1900. An “Architectural Worksheet” (Attachment C) describing the building as rectangular in plan with a hipped roof form and exterior walls sheathed in wide shiplap. The style is noted as “Classical Revival” and a porch with square columns supporting a pediment is highlighted (current photographs indicate that the square columns have been replaced). A Tiny Home has been sited at the back of the property since about 2019. 2.2 New Construction Behind this dwelling, a new two- story dwelling and garage (about 1,595 sq. ft. in total floor area) is proposed to be constructed (see Project Plans, Attachment A). The Tiny Home and a deck at the rear of the existing dwelling will be removed as part of the project. As shown in plans, the building will have tongue and groove horizontal wood siding and be topped by a hipped asphalt shingle roof. It has simple rectangular forms, incorporates a porch with exposed post and beam elements, and presents to the street view a single-wide decorative garage door with divided light windows and a low-sloped peaked roof. Windows are a mix of fixed and sliding forms, square and rectangular, with expansive sliding glass doors at the ground level, facing an enclosed courtyard area. Page 10 of 34 Item 4a ARCH-0005-2025 (1253 Mill) Cultural Heritage Committee Report – February 24, 2025 3.0 EVALUATION Guidance for new construction associated with historical resources and districts is provided in the City’s Historic Preservation Program Guidelines and the Secretary of the Interior’s Standards for the Treatment of Historic Properties.4 Relevant applicable guidelines, standards, and recommendations from these documents are outlined below. 3.1 Historic Preservation Program Guidelines Construction in Historic Districts and on Properties with Historic Resources § 3.2.1 Architectural Compatibility New structures shall be designed to be architecturally compatible with the district’s prevailing historic character 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. New structures are not required to copy or imitate historic structures, or seek to create the illusion that a new building is historic.. § 3.2.2 Architectural Compatibility New development should not sharply contrast with, significantly block public views of, or visually detract from, the historic architectural character of historically designated structures located adjacent to the property to be developed, or detract from the prevailing historic architectural character of the historic district. Discussion: The proposed new dwelling is sited at the rear of the property and at two stories in height is consistent in scale with the existing dwelling and with other dwellings in the vicinity, typically one and two stories in height. Its massing is concentrated at the ground floor, stepping back at the upper level, and conventional hipped and gable roof forms are employed. The horizontal siding, composition shingle roof material, rectangular window forms, and restrained detailing exhibit an appearance that is compatible with the simple form and style of the existing dwelling, without detracting from that dwelling’s character attempting or attempting to mimic its historic elements. 4 Kay D. Weeks and Anne E. Grimmer. The Secretary of the Interior’ s Standards for the Treatment of Historic Properties with Guidelines for Preserving, Rehabilitating, Restoring & Reconstructing Historic Buildings. Washington, D.C.: U.S. Department of the Interior National Park Service; Technical Preservation Services, 2017 Page 11 of 34 Item 4a ARCH-0005-2025 (1253 Mill) Cultural Heritage Committee Report – February 24, 2025 3.2 Secretary of the Interior’s Standards (Rehabilitation) Related New Construction Recommended Not Recommended Locating new construction far enough away from the historic building, when possible, where it will be minimally visible and will not negatively affect the building’s character, the site, or setting. Placing new construction too close to the historic building so that it negatively impacts the building’s character, the site, or setting. Designing new construction on a historic site or in a historic setting that it is compatible but differentiated from the historic building or buildings. Replicating the features of the historic building when designing a new building, with the result that it may be confused as historic or original to the site or setting. Ensuring that new construction is secondary to the historic building and does not detract from its significance Adding new construction that results in the diminution or loss of the historic character of the building, including its design, materials, location, or setting. Constructing a new building on a historic property or on an adjacent site that is much larger than the historic building. Discussion. The proposed construction is situated behind the existing dwelling, such that its visibility is partially obscured, and separated from the dwelling by about 20 feet. Though consistent in form, style, and appearance with the dwelling on the site, its tongue and groove siding, contemporary window forms, and two - story stepped form differentiate it from the existing dwelling on the property. Its scale, roof forms, window patterns, and wood siding and detailing are also compatible with the predominant architectural features described for the Mill Street Historic District in the City’s Historic Preservation Program Guidelines (see Attachment B). 4.0 ENVIRONMENTAL REVIEW The project is categorically exempt from the provisions of the California Environmental Quality Act (CEQA). It consists of construction of one single-family residence in a residential zone, as described in CEQA Guidelines § 15303 (New Construction of Small Structures.

The Mill Street District is part of one subdivision, The Town of San Luis Obispo, recorded in 1878, although the area informally has been referred to as Fremont Heights. For its land area, Mill Street Historic District has the highest concentration of historic structures of the City’s five Historic districts. It is a relatively small district, with an area of 20 acres or 0.03125 square miles, and as of January of 2010 had 84 listed historic properties. The Mill Street district was developed at the turn of the 20th century, with the majority of the existing buildings dating from the 1900s to 1920s, the district’s primary period of historical and architectural significance. The district was developed on high ground with originally very wide (100 ft) lots in response to both the seasonal flooding and fires that plagued early development in San Luis Obispo. A few of these wide lots remain in the 1300 block of both Mill Street and Palm Street, but the majority of them were later re-subdivided into 50-60 foot wide lots. Site Features and Characteristics Common site features and characteristics include: A. Trees spaced at regular intervals along the street (especially on Mill Street) B. Distinctive Camphor Trees lining both sides of Mill Street between Johnson and Pepper, a key entry corridor for the district C. Consistent street yard setbacks of 20 feet or more D. Coach barns (garages) recessed into rear yard E. Finish floors raised 2-3 above finish grade F. Front entries oriented toward street, with prominent walk, stairs and entry porches. G. Front building facades oriented parallel to street Architectural Character Developed during a population boom in San Luis Obispo circa 1900s-1920s, the district’s residential architectural styles reflect the prosperity of its residents. While older and more elaborate residences are located on the 1300 block of both Palm and Mill Streets, the majority of 1344 Mill Street, South Elevation Page 29 of 34 48 historic homes were more modest residences. The close proximity to the court house meant that Mill Street was home to many county employees, including county assessors, attorneys, and county clerks. The Mill Street District encompasses many different architectural styles, including revival styles popular at the turn of the twentieth century. These styles include Neo-classic Row House, Victorian (with elements of Gothic Revival, Queen Anne, Stick and Eastern Shingle), Tudor Revival, Mission Revival, and Craftsman Bungalow, with many homes borrowing architectural details from more than one style. Most buildings in this district were built by local builders, including E.D. Bray and James Maino and were influenced by architectural pattern books of the time period. Predominant architectural features include: A. One- and occasionally two-story houses B. Mostly gable and hip roof types C. Traditional fenestration, such as double-hung, wood sash windows, ornamental front doors, wood screen doors D. Ornamental roof features, including prominent fascias, bargeboards, prominent pediments or cornices E. Painted wood or stucco surface material, including siding and molding Individually Contributing Elements in the Mill Street District Not all historic resources in the Mill Street Historic District were built during the district’s period of significance. Those buildings date from the late 1800s, generally do not exhibit the signature architectural elements described above, but do contribute to the historic character of San Luis Obispo in their own right based on age, architectural style or historical association. By virtue of their significance, these resources also merit preservation. For example, the Buckley House at 777 Johnson Avenue is a converted carriage house built in the 1880s and is significant for its design, specifically the board and batten siding, of which there very few examples are left in the City. The Shipsey House at 1266 Mill Street, a National Register property, is an example of Eastern Stick and significant for both its architectural style and its association with William 1264 and 1270 Palm Street, South Elevation 777 Johnson Avenue, East Elevation Page 30 of 34 49 Shipsey, attorney and mayor of San Luis Obispo from 1898 to1901. Non-Contributing Elements in the Mill Street District Non -contributing buildings are those that both do not meet the criteria outlined above and have not achieved historical significance. Most of the post—1950 contemporary buildings in the district fall into this latter category. Non-contributing architectural styles, materials or site features include: A. Aluminum sliding windows B. Rectilinear, “boxy” shape C. Metal or other contemporary material siding, or “faux” architectural materials or features. D. Unarticulated wall surfaces E. Non-recessed or offset street entries to buildings 1243 Mill Street, North Elevation Page 31 of 34 50 *** 1262 Mill Street; 1261 Mill Street; 1143, 1137 and 1127 Peach Street; Righetti House, 1314 Palm Street Page 32 of 34 Reference No. Photo No. r,'l Di recti on Parcel No. Eval ation Score l.
