General Plan Advisory Committee — January 19, 2023
This was the first GPAC meeting of 2023, focused almost entirely on historic and cultural resources policy. Consultants from Page & Turnbull presented draft goals and policy frameworks for the historic preservation element of Petaluma's General Plan update, drawing substantial discussion from committee members with direct expertise in architecture, historic preservation, and development.
General Public Comment
Four members of the public spoke during the opening comment period.
Darren urged the committee to embed soil health monitoring into the General Plan, describing a handheld device (a "microbiometer") that measures soil biology. He argued that collecting baseline data on soil ecology across city-managed open spaces could yield long-term insights on environmental and public health.
Amy Hogan (speaking under a family member's login) spoke on behalf of an ongoing effort to preserve La Cresta Ridge and English Hill — approximately 23 combined acres of privately owned hillside land near downtown. She described the land's historic, ecological, and recreational significance, noting views, oak woodlands, natural springs, and a potential wildlife and pedestrian corridor connecting downtown to Helen Putnam Park.
Susan Kurtz introduced herself as an applicant for a GPAC vacancy, highlighting her 23 years of environmental volunteer work in Petaluma, an ongoing wildlife corridors and crossings mapping project for Sonoma and Marin counties, a habitat garden grant application for Petaluma schools, and a newly incorporated land trust (Conservation Trust of the North Bay). She also cautioned that some wildlife corridor information previously submitted about La Cresta Ridge was inaccurate.
Elizabeth (a second La Cresta advocate) added that the 13.7-acre La Cresta parcel is owned by Cal Water Services — not open space — and encouraged the GPAC to advocate for designating both parcels as open space in the General Plan.
Project and Staff Updates
Staff provided updates on several ongoing workstreams:
Historic Resources: Policy and Strategy Ideas (Main Agenda Item)
Christina Daikús and Hannah Simpson of Page & Turnbull presented five draft goals for the historic preservation element of the General Plan. This is an advisory body with no binding vote; the discussion below represents committee input that will shape the administrative draft.
Overview of Petaluma's historic context: The consultants noted that Petaluma ranks among California's top cities for historic building stock quality and integrity. Roughly 40% of properties are "age-eligible" (45+ years old, the threshold used for CEQA review). The city currently lacks a comprehensive inventory of eligible resources.
Goal 1 — Protect the existing historic built environment
Policies cover: maintaining historic districts through design review; requiring review before demolition of age-eligible properties; identifying previously unrecognized resources through the development review process; providing preservation incentives (fee reductions, tax credits, grants); staff education; and penalizing demolition by neglect.
Key committee discussion:
On objective design standards: staff (Heather) explained the city is still working on these and they will go through Planning Commission and Council before taking effect. The consultants noted that some state laws (e.g., SB 35) screen out historic district properties, providing some built-in recognition of their unique character.
Goal 2 — Acknowledge diverse history and expand the resource inventory
Policies cover: conducting a comprehensive citywide survey of age-eligible properties; developing a historic context statement; creating a centralized digital database; pursuing Certified Local Government (CLG) status; encouraging continued use of historic industrial and agricultural properties; supporting adaptive reuse; and protecting heritage landscape features including the Heritage Tree list.
Staff clarified that the remaining barrier to CLG status is an ordinance amendment, not a completed survey — and that finalizing that amendment is now being actively coordinated.
Bill Reinhardt recommended adding protection for historic corridors — specifically the railroad corridors and the riverfront — as character-defining features that currently fall outside formal protection. He noted that when the HCPC discussed landmarking the railroad tracks, SMART immediately removed tracks on its property. He also advocated for flexibility in Secretary of the Interior standards to allow appropriate intensification of historic downtown buildings (e.g., adding a story) when adaptive reuse demands it, while still protecting core industrial buildings that remain in active use.
Staff noted that the Central Petaluma Specific Plan includes deed notice language for new users near industrial areas, which could be a model for broader application.
Goal 3 — Connect historic preservation to climate resilience and sustainability
The guiding concept: "the greenest building is the one that's already built." Policies promote proactive retrofits, energy efficiency, salvage ordinances for demolished building materials, and relief from zoning requirements to encourage adaptive reuse.
Bill Wilbur suggested distinguishing between windows (and other elements) that must meet strict historic standards for individually designated landmarks versus contributing structures within districts — noting that modern wood-clad and fiberglass windows have improved significantly since the 1990s, when vinyl replacement windows were the only alternative. Consultants agreed this tiered approach was worth exploring and noted design guidelines are outdated and due for revision. Bill Reinhardt asked that "the greenest building is the one that already exists" be written into the preamble of Goal 3.
Goal 4 — Recognize Native American communities as active preservation participants
Policies cover: respectful treatment of archaeological resources; tribal consultation in the development review process; supporting cultural events; and developing educational signage and programming.
Aaron Chimeleski asked whether there is a map of sites significant to indigenous communities, noting the value of layered place-based history (e.g., the Fairgrounds as a WWII Japanese internment site). Consultants explained that specific archaeological site locations are often confidential to prevent vandalism, but that tribes themselves may identify places important to them in ways separate from formal archaeological inventory. Staff noted that improving the relationship with the Graton Rancheria has been an ongoing priority and requires sensitivity about what information is shared publicly.
Hannah Simpson emphasized thinking beyond buildings to "intangible cultural heritage" — festivals, Legacy businesses, community practices — as things cities are increasingly trying to recognize. Yancey Jacobo suggested murals as a venue for sharing community history and experience.
Bill Reinhardt noted that the goal language is aspirational but lacks clear assignment of responsibility for action — who will actually do the outreach and relationship-building — and recommended that the administrative draft specify implementors and timelines.
Goal 5 — Heritage tourism and public education
Policies cover: interpretive signage and public art; partnering with local organizations on tours and programming; engaging the Chamber of Commerce and regional tourism industry; and pursuing designation as a Preserve America Community (a federal advisory council program that provides recognition, grant eligibility, and tourism support).
Bill Reinhardt recommended engaging Petaluma elementary schools, noting students likely know more about California Missions than about local historic districts.
Aaron Chimeleski questioned the name "Preserve America Community" as sounding racially exclusionary in tone (though acknowledged its formal meaning). She also highlighted suggestions from GPAC member Mary Dooley (attending difficulties) around consistent street tree planting and sidewalk maintenance in historic districts, and noted the Trestle as a candidate for adaptive reuse for bikes and pedestrians.
Closing Public Comment
Two members of the public commented following the presentation.
Taryn called it one of the best city meetings she had attended and urged: exploring whether the river could be formally designated a historic landmark; adopting Mill Valley–style "character district" mapping; integrating historic design sensibility into objective standards for new development so that new buildings respect local architectural heritage; and codifying protections through ordinance rather than aspirational language.
Darren asked whether a consistent historic design reference or standards document already exists for developer and public use, suggesting such a resource would complement all the policies being discussed.

CALL TO ORDER
ROLL CALL, LOGISTICS AND MEETING OVERVIEW
GENERAL PUBLIC COMMENT During General Public Comment, the public is invited to make comments on items of public interest that are within the Committee’s subject matter jurisdiction and that are not listed on the current agenda. Public comments are limited to two minutes per person. Depending on the number of persons wishing to address the Committee, time will be allocated in equal shares totaling no more than twenty minutes.
During the general public comment period moderated by Daniel, commenter Darren raised concerns about environmental considerations that would be addressed later in the meeting. Multiple public speakers advocated for the preservation of La Cresta Ridge (13.7 acres) and English Hill (10 acres) in Petaluma, with Susan Kurtz—an environmental expert applying to join GPAC—emphasizing the ecological importance of these properties, including their wildlife habitat and natural features, while cautioning the committee to carefully review natural environment data that may contain inaccuracies. Elizabeth urged the committee to designate these 23 combined acres as open space to provide connectivity from downtown to Helen Putnam Park as the town grows. Another commenter praised staff presentations and proposed several heritage preservation measures, including making the river a historic landmark, establishing character districts similar to Mill Valley's model, and incorporating historic design standards into ordinances rather than voluntary guidelines. Darren also questioned whether the city has developed historical design reference standards that developers could consistently reference, similar to existing permeable surface standards.
PROJECT AND STAFF UPDATES a. Updates on initiatives related to the GPU b. Clarifying questions from GPAC members
Staff provided updates on multiple GPU initiatives, with Ron and Christina reporting continued work on climate and greenhouse gas production strategies in coordination with the climate action commission. Additional progress includes floodplain and sea level rise modeling—which requires coordination across police, fire, and other departments—with floodplain modeling expected later this quarter alongside land use discussions, and housing element updates with preliminary HCD comments to be redlined and posted for public review before the January 27th official comment deadline. Staff noted that recent flooding has provided valuable opportunities to validate their mathematical models against actual observed data. Administrative drafts for General Plan policy frameworks are being developed across multiple city departments, and all 16 current GPAC members have committed to continuing for at least another year, with approximately 20 new applications to be presented to Council on February 6th for appointment. Committee member Eliana raised a question about accessibility for the upcoming community mapping discussion regarding river updates, recommending both in-person and online options, which staff agreed to coordinate with anticipated engagement in early March 2023.
GENERAL PLAN POLICY AND STRATEGY IDEAS - HISTORIC RESOURCES a. Presentation by representatives from Page & Turnbull on the current status of General Plan work related to historic resources, with a focus on policy and strategy ideas in light of GPAC Working Group recommendations b. Clarifying questions from GPAC members c. Public comment d. Discussion between the consultants, City staff, and GPAC members regarding historic resources policy and strategy ideas
Staff, alongside architectural historians Christina Daigus and Hannah from Page and Turnbull, presented a comprehensive historic resources framework for the General Plan update, covering Petaluma's top-tier historic building stock, existing regulatory frameworks, and proposed policy updates aligned with current best practices. The presentation outlined five preliminary goals: (1) retaining and enhancing the historic built environment through designation and project review; (2) acknowledging diverse history by expanding surveys beyond previously designated properties; (3) connecting sustainability with historic preservation through adaptive reuse; (4) recognizing Native American communities as active participants in tribal cultural resource preservation; and (5) promoting heritage tourism and public engagement. Committee members, particularly Bill Reinhardt, emphasized the need for explicit language on permanent funding mechanisms, objective design standards that allow modern materials while maintaining historic character, protection of overlooked resources like industrial buildings and railroad corridors, and clear responsibility assignments with specific implementors and timeframes for all action items. Key implementation strategies discussed included demolition review for 45+ year-old properties, design guidelines based on Secretary of Interior standards, incentive programs (tax credits, state historic building code, fee reductions), salvage ordinances, and pursuit of Certified Local Government status to unlock grant opportunities—though staff noted that uncertain future funding and challenging market conditions in Petaluma require balancing ambitious goals with realistic implementation and tailored incentive/disincentive approaches.

# Committee Member General Comment SummaryDuring the general comment period, GPAC member Darren advocated for embedding soil health analysis into the General Plan, proposing that Parks and Rec and Public Works use microbiometer devices to measure bacterial and fungal populations in city-owned spaces as part of their regular processes to capture long-term ecological data, noting that other organizations are already building public databases correlating soil health with public health outcomes. Committee member Amy Hogan emphasized the importance of preserving La Cresta Ridge and Ravine, highlighting its historical significance as Petaluma's original 1938 western city boundary and its value as a long-standing passive recreation area for residents, supported by historical photographs dating from 1910-1920. Committee chair Ron noted that no additional comments were raised and expressed the committee's anticipation for the February meeting and incoming GPAC members.
What happened
Christina Paul provided closing remarks, thanking the translators, PCA staff, Ron and other committee members, and noting the importance of public access, Spanish language recording, and website posting of meeting materials. She indicated new members would be joining the committee for future meetings.Verbatim transcript available
