Term Description
AMI Advanced Metering Infrastructure (AMI) is an integrated system of smart meters, communications networks, and data management systems that enables two-way communication between utilities and customers.

API Application Programming Interface (API) is a way for two or more computer programs to communicate with each other. It is a type of software interface, offering a service to other pieces of software.

CIS Customer Information Systems is a system for managing information about customers in the context of a Utility’s relationship to those customers.

CSR A Customer Service Representative is the first person most customers communicate with when they have a problem. The Customer Service Representative must handle complaints, provide appropriate solutions for customers, and follow up to resolve any issues their customers experience.

E-Bill E-Bill means the online data access services provided by a Utility to you to enable you to access via the Internet your current and accumulated historic invoices from the Agreement Date.
e-check An e-check works quite a bit like a regular check, but instead of tearing a piece of paper out of your check book, you provide payment information (like your bank account, routing number, and payment authorization) through an e-check authorization form. This prepares your payment to be processed electronically.

MDM Meter Data Management (MDM) refers to software that performs long-term data storage and management for the vast quantities of data delivered by smart metering systems.

PROD
(PRODUCTION)
This is the environment in which the software will be used for customers and the utility’s daily activities. Also known as LIVE.

REST A RESTful API is an architectural style for an application program interface (API) that uses HTTP requests to access and use data. That data can be used to GET, PUT, POST and DELETE data types, which refers to the reading, updating, creating and deleting of operations concerning resources.

Smart Meter A smart meter is an electronic device that records information such as consumption of electric energy, voltage levels, current, and power factor.

Smart meters communicate the information to the consumer for greater clarity of consumption behavior, and electricity suppliers for system monitoring and customer billing.

SOAP Simple Object Access Protocol (SOAP) is a messaging protocol specification for exchanging structured information in the implementation of web services in computer networks. It uses XML Information Set for its message format, and relies on application layer protocols, most often Hypertext Transfer Protocol (HTTP), although some legacy systems Item 6.d

Term Description
communicate over Simple Mail Transfer Protocol (SMTP), for message negotiation and transmission.

SSL Secure Sockets Layer (SSL) is a standard security technology for establishing an encrypted link between a server and a client—typically a web server (website) and a browser, or a mail server and a mail client (e.g., Outlook).

SSO Single Sign-On (SSO) is an identification method that enables users to log in to multiple applications and websites with one set of credentials.

UAT User Acceptance Testing (UAT) is the last phase of the software testing process. During UAT, actual software users test the software to make sure it can handle required tasks in real-world scenarios, according to specifications
VPN A Virtual Private Network (VPN) establishes a digital connection between your computer and a remote server owned by a VPN provider, creating a point-to-point tunnel that encrypts your personal data, masks your IP address, and lets you sidestep website blocks and firewalls on the internet.

WSDL Web Services Description Language (WSDL) is a standard specification for describing networked, XML-based services. It provides a simple way for service providers to describe the basic format of requests to their systems regardless of the underlying run-time implementation.

CITY OF HEALDSBURG

CITY COUNCIL AGENDA STAFF REPORT
MEETING DATE: October 5, 2026
SUBJECT: Workforce and Middle-Income Housing Policy Findings PREPARED BY: Stephen Sotomayor, Housing Director
STRATEGIC INITIATIVE(S):
 Expand Affordable Housing Opportunities
RECOMMENDEDACTION(S):

Adopt a Resolution reaffirming the need for workforce and middle-income housing and recognizing community-based efforts to advance existing City housing objectives.

COMMUNITY ENGAGEMENT/OUTREACH:

This item will be considered at a public City Council meeting with an opportunity for public comment. The subject has also been discussed through the Housing Element Work Group and prior public City Council presentations.

BACKGROUND:

The City has been working to address workforce and middle-income housing needs for more than a decade. In 2015, the City Council established the Community Housing Committee to examine affordable and workforce housing needs. The committee’s work resulted in the Housing Action Plan, which identified middle-income housing as a distinct community need. This work continued through the adoption of a revised Housing Action Plan in 2018.

In November 2018, Healdsburg voters approved Measure P, a local ballot measure allowing an average of up to 50 additional income-restricted multifamily rental homes per year, with no more than 150 homes over three years, for households earning up to 160 percent of area median income.

In March 2020, voters approved Measure H, which extended this authorization to qualifying income-restricted ownership homes. Both ballot measures received broad community support and demonstrated the community’s interest in creating additional housing opportunities for local workers and middle-income households.

In 2021, City Council established the Housing Element Work Group to assist with preparation of the 2023–2031 Housing Element and consideration of related policy questions. Through Resolution No. 171-2022, City Council directed further study of housing needs and funding, Item 6.e
188 of 1062
middle-income homeownership, downtown housing capacity, and the Growth Management Ordinance.

On May 1, 2023, City Council adopted the 2023–2031 Housing Element. On June 29, 2023, the California Department of Housing and Community Development certified the Housing Element.

The Housing Element includes several policies and programs directly related to the need for workforce and middle-income housing:
 Policy 3.4 directs the City to expand housing opportunities for middle-income households.  Policy 4.8 calls for moderate- and middle-income ownership housing in cooperation with the Housing Land Trust of Sonoma County or similar organizations.  Housing Program 3 directs the City to pursue site acquisition and land banking and to consider establishing or supporting a housing trust or community development corporation.  Housing Program 5 recognizes that producing housing for households earning up to 160 percent of area median income is difficult because of high land and development costs and limited subsidy sources. It identifies mixed-income development, land-trust models, employer partnerships, subsidy tools, and opportunity sites as potential implementation strategies and calls for facilitating at least 50 middle-income ownership homes before 2030.

In December 2023, following adoption and certification of the Housing Element, the Housing Element Work Group reviewed the methodology and preliminary results of the Housing Needs Calculator. The analysis examined local employment, wages, housing costs, and the number of additional homes needed to increase the share of people who work in Healdsburg and can also live in the community.

The City Council’s adopted housing goals also include facilitating exploration of a community housing land trust to secure land for future housing needs and expand moderate- and middleincome housing opportunities.

On March 3, 2025, consistent with that goal, City Council received a presentation on housing trust funds and land-trust models as potential tools for implementing the City’s adopted housing policies.

On March 2, 2026, a community group returned to City Council to present its plans for an independent nonprofit housing organization. In April 2026, the group incorporated the Healdsburg Housing Trust as an independent California nonprofit public benefit corporation. The organization is now pursuing recognition under Internal Revenue Code section 501(c)(3).

The City did not form the organization and has participated only in a facilitative and informational capacity.

DISCUSSION/ANALYSIS:

Why the Housing Need Remains
Healdsburg has successfully produced housing for lower-income households through inclusionary requirements, public subsidies, and partnerships with affordable housing developers. Those tools Item 6.e
189 of 1062
remain essential, but they do not fully address households that earn too much to qualify for conventional affordable housing programs and still cannot afford the local market. The gap includes local workers and moderate- and middle-income households earning between 80 and 160 percent of Sonoma County AMI. Public funding and conventional affordable housing financing are limited for this segment, particularly when high land costs must also be absorbed.

The Housing Needs Calculator, prepared by Economic & Planning Systems, Inc. (EPS) for the City of Healdsburg in 2023, illustrates the scale of the problem. It found that only 842 of the 5,613 primary jobs located in Healdsburg in 2020 were held by City residents, approximately 15 percent, compared with 24.5 percent in 2002. The study also showed that many of Healdsburg's largest occupational groups earn substantially less than the income needed to purchase a median-priced home. Under the EPS 2023 assumptions, a household needed approximately $190,000 annually to purchase a $1.038 million median-priced home, more than 160 percent of the applicable threeperson AMI benchmark.

The consequences extend beyond individual housing costs. A July 17, 2025, San Francisco Chronicle analysis of Census data reported that the share of Healdsburg residents under age 18 declined from 25 percent in 2009 to 17 percent in 2023, the largest decline among Bay Area cities with at least 10,000 residents. The article connected the trend to housing cost and availability and described the difficulty experienced by younger families, service workers, teachers, firefighters, and nurses seeking to live in the community. This is consistent with the City's own findings that workforce housing affects community continuity, schools, employers, and public services.

Purpose and Effect of the Resolution
The Healdsburg Housing Trust requested that the City Council adopt a resolution containing findings to support its application for federal tax-exempt status. Federal guidance provides an established safe harbor for certain charitable housing activities serving lower-income households.

Because the Healdsburg Housing Trust also intends to address workforce and middle-income housing needs outside those conventional limits, its application relies in part on a separate charitable basis: lessening the burdens of government.

Under this standard, the record must demonstrate that the proposed non-profit activities would advance a governmental function or policy objective already recognized by the City and that the organization would meaningfully assist the City in advancing that objective. The proposed resolution brings together the City’s existing policy record, including the Housing Action Plan, Housing Element, Council goals, EPS analysis, and prior public actions. It does not establish a new policy or expand the City’s role; it documents housing needs and objectives the City Council has previously identified and adopted.

The resolution also recognizes that community-based land acquisition and banking, private and philanthropic funding, partnerships, project coordination, and long-term affordability stewardship could help advance the City’s existing Housing Element programs while reducing financial and administrative demands on limited municipal resources.

The Internal Revenue Service, not the City, will determine whether the organization qualifies for federal tax-exempt status. Adoption of the resolution would not:

Item 6.e
190 of 1062
 Endorse or designate a particular organization to act on behalf of the City;  Establish a new City housing program or direct additional staffing or reporting;  Commit City funding, property, or services;
 Approve a housing project, agreement, or formal partnership; or  Amend land-use regulations, income eligibility standards, or affordability requirements.

Any future request involving City funding, property, services, regulatory assistance, or a formal partnership would return to the City Council for separate consideration and any required approvals.

ENVIRONMENTAL STEWARDSHIP:

Not applicable.

ALTERNATIVES:

The City Council may decline to adopt the resolution or direct staff to revise the proposed findings.

FISCAL IMPACT:

There is no fiscal impact associated with adopting the proposed resolution. No funding or other City commitment is requested.

ENVIRONMENTAL ANALYSIS:

Adoption of resolution with policy findings does not constitute a project under the California Environmental Quality Act pursuant to CEQA Guidelines section 15378(b)(5), because the action is administrative and will not result in a direct or indirect physical change in the environment.

CITY OF HEALDSBURG
RESOLUTION NO. ____-2026

A RESOLUTION OF THE CITY COUNCIL OF THE CITY OF

HEALDSBURG REAFFIRMING THE NEED FOR

WORKFORCE AND MIDDLE-INCOME HOUSING AND

RECOGNIZING COMMUNITY-BASED EFFORTS TO

ADVANCE EXISTING CITY HOUSING OBJECTIVES
WHEREAS, the availability of housing affordable to households across a range of incomes is essential to Healdsburg's community stability, economic diversity, local workforce, schools, businesses, and public services; and
WHEREAS, the City has long recognized a gap between housing available through conventional income-restricted programs and housing attainable in the private market, including homes for households earning more than 80 percent and up to 160 percent of Sonoma County area median income (AMI), adjusted for household size; and
WHEREAS, the City Council established the Community Housing Committee (CHC) in 2015 to examine affordable and workforce housing needs, and that work identified middle-income housing as a distinct unmet community need; the Council subsequently reestablished the CHC through Resolution No. 28-2017 and adopted the revised Housing Action Plan on February 5, 2018; the Housing Action Plan and related public process addressed middle-income housing, growth management, housing types, funding, and partnerships with nonprofit developers and housing trusts; and
WHEREAS, Healdsburg voters demonstrated broad community support for expanding workforce and middle-income housing opportunities by approving Measure P in November 2018, which allowed, under the City’s voter-approved Growth Management Ordinance, an average of up to 50 additional income-restricted multifamily rental homes annually, not to exceed 150 homes over three years, for households earning up to 160 percent of area median income; and by approving Measure H in March 2020, which extended that authorization to qualifying incomerestricted for-sale homes; and WHEREAS, the Council established the Housing Element Work Group (HEWG) on June 7, 2021, and through Resolution No. 171-2022 approved further study of housing needs and funding, middle-income homeownership, downtown housing capacity, and the Growth Management Ordinance; and
Item 6.e
192 of 1062
WHEREAS, the City Council adopted the 2023–2031 Housing Element on May 1, 2023, and the California Department of Housing and Community Development certified it on June 29, 2023; Policies 3.4 and 4.8 support middle-income housing opportunities and cooperation with land-trust organizations; Program 3.2 identifies site acquisition and land banking, including consideration of a housing trust or community development corporation; and Program 5.4 recognizes limited public subsidies and high land and development costs as barriers, identifies land-trust models, employer partnerships, and other financing tools, and calls for facilitating at least 50 middle-income ownership homes before 2030; and WHEREAS, the November 2023 Housing Needs Calculator prepared by Economic & Planning Systems, Inc. (EPS) reported that only 842 of the 5,613 primary jobs located in Healdsburg in 2020, approximately 15 percent, were held by Healdsburg residents, a decline from

24.5 percent in 2002 and evidence of a growing disconnect between local employment and local residency; and
WHEREAS, using separate JobsEQ employment estimates for the first quarter of 2023, the Housing Needs Calculator found that more than one-third of Healdsburg’s jobs were in food preparation and serving, sales, and office and administrative support, with reported annual wages ranging from approximately $37,400 to $51,300; other important local occupations, including education and construction, also had wages substantially below the income needed to purchase a home in Healdsburg; and
WHEREAS, at the time of the analysis, the Housing Needs Calculator estimated that a household would need approximately $190,000 in annual income to purchase the median-priced Healdsburg home, an amount above 160 percent of area median income and beyond the reach of many local workers and two-earner households that do not qualify for traditional affordable housing programs; and
WHEREAS, the Housing Needs Calculator estimated that approximately 895 additional homes would be needed over the modeled 2023–2031 period to enable 30 percent of the people working in Healdsburg to also live in the community, illustrating the scale of the City’s workforce housing need; and
WHEREAS, Census Bureau 2020-2024 estimates show a Healdsburg median household income of $103,554, a median owner-occupied home value of $950,100, and median gross rent of $2,158 per month; and
WHEREAS, the State publicly announced Healdsburg's Prohousing designation on January 31, 2024, recognizing the City's efforts to facilitate housing production; and Item 6.e
193 of 1062
WHEREAS, the 2024 Downtown Housing Capacity Study identified high demand, limited supply, and the then-applicable 16-unit-per-acre density limit as barriers to workforce housing; the study and companion analysis examined how regulatory changes could make additional homes feasible, and the study recommended considering targeted relief from the Growth Management Ordinance; and
WHEREAS, a May 6, 2024, City Council staff report noted that no new middle-income multifamily homes had been constructed during the six years following approval of Measure P; later that year, Measure O proposed targeted changes to the Growth Management Ordinance intended to encourage multifamily housing along the Healdsburg Avenue corridor but was not approved by voters; together, these efforts demonstrate that regulatory authorization alone has not been sufficient to produce middle-income housing; and
WHEREAS, the City Council’s adopted housing goals include facilitating exploration of a community housing land trust to secure land for future housing needs and expand moderate- and middle-income housing opportunities; on March 3, 2025, the Council received a presentation on housing trust funds and land-trust models, followed by a community-led presentation on March 2, 2026, regarding formation of an independent nonprofit housing organization; and WHEREAS, the City’s Housing Element and related plans and studies recognize that municipal resources and regulatory actions alone cannot meet the full range of the community’s housing needs; community-based organizations can contribute land, private and philanthropic resources, partnerships, and project coordination to help implement the City’s adopted housing objectives and address housing needs identified through the state-mandated Regional Housing Needs Allocation (RHNA) process;
NOW, THEREFORE, BE IT RESOLVED that the City Council of the City of Healdsburg affirms as follows:

Section 1. Existing Housing Need and Municipal Purpose
The foregoing recitals are incorporated into this Resolution as findings. Addressing the documented shortage of workforce and moderate- and middle-income housing is a longstanding municipal purpose and adopted policy objective reflected in the City’s Housing Element, housing programs, and Council goals. These efforts remain important to the community’s economic and social well-being.

Section 2. Contribution of Community-Based Housing Efforts The Council recognizes that community-based land acquisition and banking, coordination of private and philanthropic resources and partnerships, project coordination, and long-term affordability stewardship may help advance existing Housing Element Programs 3.2 and 5.4.

When undertaken in support of those programs, these activities may assist the City in advancing Item 6.e
194 of 1062
its adopted housing objectives and reduce the financial and administrative demands placed on limited municipal resources.

Section 3. Scope and Limitations
This Resolution affirms existing City housing objectives. It does not establish a new housing program or commit to establishing any new program(s); direct additional staffing or reporting; commit City funding, property, or services; approve a project or agreement; designate or authorize any organization to act on behalf of the City; or amend existing land-use regulations, income eligibility standards, or affordability requirements.

PASSED AND ADOPTED by the City Council of the City of Healdsburg, this 5th day of October, 2026, by the following vote:

Adopt a Resolution (Attachment 1) denying an appeal (APPL-0001-2026), affirming the Planning Commission’s approval of Conditional Use Permit CUP-0001-2026 and density bonus for a project located at 359 Hudson Street, consisting of a 67-unit senior living and memory care facility, 10 affordable housing units and associated site improvements (APN-002-291-033), and amending Condition of Approval 1 to reflect updated plans for the 10 affordable housing units.

COMMUNITY ENGAGEMENT/OUTREACH:

The City published proper notice of this City Council public hearing, including in the Healdsburg Tribune, mailed notice to property owners within 300’ of the proposed project’s property boundary, and notice was provided on site.

BACKGROUND:

On April 2, 2025, the applicant held a community meeting on site, at which members of the public were provided preliminary information about the potential project.

On April 8, 2025, the Planning Commission held a workshop where they reviewed and offered initial feedback on the proposed project.

On October 3, 2025, the City received a Housing Accountability Act (HAA) application for the project. The application included the project proposal, site plan, initial elevations, and proposed colors and materials.

On February 10, 2026, the City received a formal application for the proposed project, which included a Major Design Review, Conditional Use Permit, Tentative Map, requested density bonus and associated incentives and waivers (the “Project”).

Item 7.a
196 of 1062
On June 3, 2026, City staff determined the application for the Project was complete.

On July 4, 2026, City staff deemed the Project consistent with applicable standards pursuant to the HAA.

On August 11, 2026, the Planning Commission, after conducting a duly noticed public hearing, approved the Project and found it exempt from the California Environmental Quality Act (CEQA) by a vote of 5-0.

On August 20, 2026, appellants submitted a timely appeal (“Appeal”) of the Planning Commission’s approval of the Conditional Use Permit and density bonus (Attachment 2).

PROJECT DESCRIPTION:

The Project comprises a Continuing Care Retirement Community (CCRC) (senior housing and residential care facility) and affordable housing development at 359 Hudson Street. The Project would redevelop the approximately 3.61-acre site with a four-story senior living building containing 67 independent and assisted living units, an associated single-story six-bed memory care building with one manager's unit, and a separate parcel containing 10 deed-restricted affordable housing units.

The Project includes subdivision of the property into two parcels, one for the senior living community and one for the affordable housing component, together with associated site improvements, landscaping, parking, pedestrian circulation, utilities, and open space.

The senior living community is designed to provide housing and supportive services for older adults, including assisted living and memory care, along with resident amenities such as dining facilities, recreational spaces, wellness areas including a medical suite for home-health visits, landscaped courtyards, and outdoor gathering areas. The Project application expressly states that the Project will not include skilled nursing services.

The affordable housing component consists of 10 rental units, including eight units affordable to very-low-income households and two units affordable to low-to-moderate income households, supported by on-site parking and residential amenities. Usually, the City’s Inclusionary Housing Ordinance (IHO) would require a housing project to provide larger affordable units and a broader mix of bedroom counts but, here, the applicant requested a concession/incentive under State Density Bonus Law to permit smaller affordable units and eliminate the City’s Inclusionary Housing Ordinance’s requirement. At the Planning Commission hearing, multiple Planning Commissioners encouraged the applicant to increase the unit sizes.

In response to the Planning Commission and community concerns raised at the August 11, 2026 Planning Commission meeting, the applicant has since proposed to increase the size of the affordable housing units from approximately 380 square feet to approximately 700 square feet. To do so, the applicant proposes to add an additional story to the affordable buildings, while keeping them within the allowable 40’ height limit for the MU Zoning District. As proposed, all of the affordable units will include one bedroom and 1.5 baths per unit, and the onsite parking count will Item 7.a
197 of 1062
remain the same. The applicant has proposed no changes to the senior living community. Revised plans are included as Attachment 6.

The Project includes a 50% density bonus, three incentives and concessions, and multiple waivers of development standards pursuant to State Density Bonus Law.

SITE AND VICINITY DESCRIPTION:

The Project site is located at 359 Hudson Street on the north side of Hudson Street. The site consists of approximately 3.61 acres and is the former Healdsburg Lumber location. The site is fully developed, relatively flat and is served by existing public streets and municipal water, wastewater, and storm drainage infrastructure.

The Project site is a split zoned parcel with zoning designations as Mixed Use and R-1-6,000 and Mixed Use (MU) and Medium Density Residential (MR) General Plan Land Use Designations, respectively.

The surrounding area is characterized by a mix of residential and commercial uses. Single-family residential neighborhoods are located to the north, west, and east. Commercial and mixed-use development is located to the east and south. The Project site is within walking distance of the downtown commercial district, public parks, transit services, and other neighborhood-serving amenities and uses.

The site is located within an established neighborhood where a range of housing types and community services already exist. The proposed redevelopment of the underutilized Project site is intended to provide additional housing opportunities within the City.

STANDARD OF REVIEW:

The City Council’s review of the appeal is de novo. In considering the Appeal, the City Council may consider the administrative record and additional evidence offered before or at the hearing and may affirm, reverse, or modify, in whole or in part, the action appealed. The City Council may also make or substitute additional decisions or determinations as warranted under the Healdsburg Municipal Code and consistent with State law.

Item 7.a
198 of 1062
DISCUSSION/ANALYSIS:

The Planning Commission approved the Project on August 11, 2026. In doing so, the Planning Commission found the Project to be consistent with the General Plan and Healdsburg Land Use Code (zoning code), as well all applicable development standards. After approval, a timely Appeal was filed. The Appeal’s assertions and staff’s response are provided below.

Appeal Issues and Staff Response
Appeal Issue No. 1
“The Hudson is not a conditionally permitted use under the applicable zoning ordinances.” Appellants claim that the Project is not a conditionally permitted use because it is a Residential Care Facility for the Elderly (“RCFE”) and includes memory care and an on-site medical suite, and therefore constitutes a medical use that is not permitted in the MU or R-1-6,000 districts. The Appellants contend that these components go beyond the City’s definition of “residential care, general,” which is allowed in the MU and R-1-6,000 zones by CUP. Further, the Appellants contend that, prior to approval, the City was required to adopt a zoning overlay expressly authorizing senior housing components such as assisted living and memory care, similar to the zoning overlay adopted in advance of the City’s approval of the North Village project (which includes Enso Village, another senior living/assisted living/memory care project in the City). .

Staff’s Response:

Appellants’ assertion is incorrect. The Healdsburg Land Use Code expressly allows “residential care, general” uses with a Conditional Use Permit in the MU and R-1-6,000 zones. Residential care, general is defined as “a State-licensed facility, place or structure that is maintained and operated to provide non-medical residential care, day treatment or foster agency services for seven or more adults and/or children as defined in the California Health and Safety Code. This use includes the administration of limited medical assistance (e.g., dispensing of prescribed medications).” (HMC § 20.28.310.) The Project is a Continuing Care Retirement Community (CCRC), a subset of RCFEs. The Applicant has stated that the Project will provide housing and residential services, and not skilled nursing or medical care beyond “limited medical assistance.” The application expressly states that the project will not provide skilled nursing services.

Operationally, the Project will be required to comply with the Land Use Code’s use definition and requirements meaning that, if the Project provides services beyond those authorized in the zoning code and the CUP, the City could initiate revocation proceedings.

The fact that the Project includes residential intake and periodic assessments, memory care, and an on-site medical suite for home health purposes does not change the Project's zoning classification. The record indicates that the medical suite will not be staffed by Project personnel and instead will be available for residents to receive occasional visits from their own personal medical providers. The Planning Commission therefore appropriately concluded that these features do not transform the Project into a prohibited medical use.

Periodic residential assessments also do not change the Project’s zoning classification. The record indicates that assessments would help ensure that residents who do need skilled nursing or medical care are transferred to another facility capable of providing said care. Further, there is nothing in the record that indicates that the Project proposes any use beyond “residential care, general.” The Item 7.a
199 of 1062
record does contain, and the Appeal offers additional opinion regarding whether Applicant is accurately describing the care it will be providing, or whether the Project will provide care in addition to that which is described in the application. However, the City’s decision must be based on substantial evidence in the record, not speculation.

As to the Enso Village project, “residential care, general” was already a conditionally permitted use in the applicable zoning district. The North Entry Area Plan (“NEAP”) Overlay added development standards to encourage senior housing and a comprehensive development plan. The NEAP did not create the underlying permission for the CCRC or RCFE use. Residential Care, General uses were already allowed with a CUP; adoption of the NEAP had no impact on the fact that Residential care, general was an allowed use in the CUP, just as it is here. Just as the City did not need a zoning overlay to issue a CUP for the Enso project, it does not need a zoning overlay to issue a CUP for this project.

The Enso Village project was part of a larger mixed use master development, and included 221 independent senior living units as well as 54 assisted living/memory care beds, and pursuant to the “residential care, general” zoning designation and development standards in the NEAP Overlay, sought and was granted a Major Design Review and Major Conditional Use Permit. In granting the Enso Village CUP, the Planning Commission found:
“The proposed Project has a use type designation of “residential care, general” in the Land Use Code. Both the use type and the Project location are consistent with the Mixed Use (MU) District and the North Entry Area Plan (NEAP) Overlay as established in the Land Use Code. As detailed in the staff report for Major Design Review Permit DR 2020-09 and Exhibit 17 (Land Use Code Consistency Analysis), the Enso Village Project complies with the applicable development standards of the Land Use Code.” (Enso Village 11/17/2020 Staff Report, p. 11.)
The proposed Project proposes the same types of uses as Enso Village. Accordingly, staff has processed this Project in a manner consistent with the approach for Enso Village.

The Project was therefore appropriately approved by the Planning Commission.

Appeal Issue No. 2
“The Hudson’s Density Bonus application is insufficient because it lacks a marketing plan.” Appellants claim that the Project’s density bonus application is incomplete because it did not include the required marketing plan, income-verification methods, and financing mechanism for the affordable housing units.

Staff Response:

The absence of a marketing plan did not make the density bonus application insufficient or prevent approval. Although the Healdsburg Land Use Code calls for a marketing plan, State Density Bonus Law prohibits the City from making such an additional submission a prerequisite to reviewing or approving a density bonus. Accordingly, the City’s published application checklist omits this requirement. The City has nevertheless addressed the substance of the requirement through Item 7.a
200 of 1062
Condition of Approval No. 24, which requires the applicant submit a marketing plan along with an approved affordable housing agreement, which will be recorded and run with land, before issuance of the first Certificate of Occupancy.

The Planning Commission correctly concluded that the density bonus could properly be approved without a marketing plan at the application stage because State law preempts treating the plan as a prerequisite, while the City preserved the substantive requirement through a condition of approval.

Later Correspondence from Appellants
After filing the Appeal on August 20, 2026, Appellants submitted several additional items of correspondence to the City. These items were submitted after the appeal deadline, but have nevertheless been included in the record and are summarized and addressed as follows:

1. August 31, 2026 Letter to Planning Commission
Appellants request that the Planning Commission revoke the CUP pursuant to HMC Section

20.28.195(E)(1), asserting that the CUP approval was based on erroneous or misleading information provided by the Applicant. The letter provides examples of job postings and staffing materials that Appellants contend demonstrate that the Project will provide medical care that exceeds the Project’s zoning, according to Appellants’ interpretation of the City’s Land Use Code.

Staff Response:

The Planning Commission’s August 11, 2026 approval of the CUP is the subject of the current appeal to the City Council, and remains pending. There is currently no CUP to revoke.

Moreover, the cited job postings appear to concern the Applicant’s general California operations or identify positions at other facilities operated by the Applicant. One job posting appears to be from 2015. The cited job postings do not mention the Project or Project site and do not establish that medical staff will be employed at the Project, or that any such staff would be hired to provide medical services beyond the “limited medical assistance” allowed for under the Residential Care, General zoning designation. The Appellants’ conclusions regarding the nature of services to be provided at the Project appear speculative and do not establish that the information presented to the Planning Commission during the August 11, 2026 meeting was false or misleading.

2. August 31, 2026 Letter to City Council
Appellants’ letter to the City Council attached the letter discussed in No. 1, above, and requested that the City Council postpone consideration of this Appeal until the Planning Commission considers the Appellants’ request to revoke the CUP.

Staff Response:

Appellants’ request is based on the same materials discussed above, including job postings and staffing materials that concern Applicant’s general operations or other facilities operated by the Applicant. The materials do not establish that medical services beyond “limited medical assistance” will be provided at the Project. Appellants’ characterization of these materials as establishing false statements is speculative and, as stated above, do not meet the standard for “substantial evidence”.

Item 7.a
201 of 1062

3. September 8, 2026 Letter to Planning Commission, with Copy to City Council Appellants’ correspondence reiterates their contention that Applicant’s testimony during the August 11, 2026 Planning Commission meeting was false, and cites additional job postings and records concerning Applicant’s other facilities – principally the Varenna facility in Santa Rosa – as additional support for Appellants’ contention that the Project’s CUP should be revoked.

Staff Response:

The cited postings concern positions at Varenna and Park View Place, or Applicant’s broader operations, and do not establish that the Project would provide medical services or care beyond “limited medical assistance” as allowed by the Residential Care, General zoning designation.

Similarly, the cited Department of Social Services records appear to concern alleged operational deficiencies at Varenna, and do not discuss land use deficiencies of the Project, or establish that information provided to the Planning Commission regarding the Project was false or misleading.

While the materials may describe services provided at other facilities operated by the Applicant, they do not provide evidence that the Project was misrepresented.

4. September 24, 2026 Submission to City Council
Appellants contend that other facilities operated by the Applicant employ licensed Registered Nurses and Licensed Vocational Nurses who provide health assessments and treatment of certain conditions, and that this constitutes professional medical care beyond the “limited medical assistance” allowed under the Residential Care, General use. Appellants again contend that job postings for positions at other facilities operated by Applicant contradict testimony provided by Applicant at the August 11, 2026 Planning Commission meeting regarding staffing and medical services at the Project.

Further, Appellants interpret California RCFE statutes and regulations as distinguishing between “limited medical assistance,” such as assistance with medications and routine medical services, and professional medical care provided by licensed personnel. Appellants contend that the Healdsburg Municipal Code permits only the former in the applicable zones and that professional medical care therefore falls outside the conditionally-permitted residential care use.

Staff Response:

Staff agrees that the Healdsburg Municipal Code limits the level of medical care in Residential care, general uses to “limited medical assistance,” such as assistance with medications and routine medical services. Professional medical services, such as those provided by doctors’ offices, skilled nursing facilities, and hospitals, would fall outside the conditionally-permitted residential care use.

However, the Project does not propose skilled nursing, doctor or hospital care. The Project includes an onsite medical suite; however, the record indicates that the medical suite will be for the use of residents to receive visits from their own personal doctors and nurses, similar to home health or doctor house calls. As above, the Planning Commission appropriately concluded that these features do not transform the Project into a prohibited medical use. Periodic residential assessments also do not change the Project’s zoning classification. The record indicates that assessments would help ensure that residents who need skilled nursing or medical care are appropriately transferred to another facility capable of providing said care. Again, there is nothing in the record, aside from speculation, that indicates that the Project proposes any use beyond “residential care, general.” Item 7.a
202 of 1062
Appellants also provide job postings and resident-assessment materials from other facilities operated by the Applicant. These materials do not necessarily reflect the specific services, staffing or operational practices of the Project. Similarly, the fact that the Applicant employs nurses does not establish that this particular Project will provide medical care and thus constitutes a different land use under the City’s zoning code.

Having reviewed the additional materials, staff does not find that the information presented establishes that the CUP was approved based on erroneous or misleading information, or that the proposed use is inconsistent with the applicable zoning regulations.

Additional Submission from Applicant:

On September 28, 2026, Applicant submitted updated Project plans that show larger affordable units in response to concerns raised by City staff, the Planning Commission and the public. The proposed changes increase the size of the affordable housing units from approximately 380 square feet to approximately 700 square feet and will comprise all one-bedroom units with 1.5 baths per unit.

The submitted plans show that this increased size would be accomplished by adding an additional story to the two affordable housing buildings, bringing the overall height of those buildings to approximately 33 feet. This would still be under the 40 foot height limit for the MU zone. The overall building footprints and onsite parking count would remain the same. No changes to the number of affordable units or their affordability levels are proposed. No changes are proposed to the senior residential community.

In addition, the Applicant submitted correspondence from its CEQA consultants that these modifications would not result in any new or increased environmental impacts, and that the Project would still qualify for a Class 32 CEQA Exemption (Infill).

In addition, the Applicant submitted a marketing plan.

These items have been included in the record and are attached to this Staff Report.

Staff Response:

Staff has reviewed the updated plans and CEQA documents and determined that they require no changes to the Project approval findings, including the CUP, Design Review, Density Bonus and Tentative Map, or the CEQA determination. In addition, the updated plans more closely align with the goals of the City’s Inclusionary Housing Ordinance.

To ensure that the Project implements the updated plans showing larger affordable units, Staff recommends amending Condition of Approval 1 as follows:

The project shall be developed in accordance with the architectural and landscape plans dated July 29, 2026, including the height revision, all as approved by the Planning Commission on August 11, 2026, with the exception of the ten affordable units, which shall be developed in Item 7.a
203 of 1062
accordance with the plans date-stamped September 29, 2026 and approved by the City Council on October 5, 2026, except as conditioned or modified herein.

HCD Correspondence
On September 28, 2026, the City received email correspondence from the California Department of Housing and Community Development (HCD) regarding the Project and this Appeal. In its correspondence, HCD advised that the Project qualifies as a “housing development project” under the Housing Accountability Act (HAA), and therefore may only be disapproved if the City makes written findings, supported by a preponderance of evidence in the record, that the Project would result in a specific, adverse impact on public health or safety and that the impact cannot be feasibly mitigated. The correspondence is included in Attachment 5.

HCD also highlighted the City’s certified 6th Cycle Housing Element, which identifies seniors as a population with special housing needs, and includes policies supporting senior housing in locations accessible to transit, commercial services, healthcare, and community facilities. The correspondence also discussed the City’s obligation to affirmatively further fair housing (AFFH), noting that the Project would provide affordable housing for very low- and low-income households.

The correspondence includes a reminder of the state’s housing crisis and encourages the City Council to deny the Appeal and uphold the Planning Commission’s approval of the Project. HCD also noted that, pursuant to Government Code Section 65585(j), HCD has authority to enforce the HAA, Housing Element Law, and AFFH requirements.

Project Findings:

Conditional Use Permit
Based on the evidence in the record, staff has determined that none of the findings required to deny the CUP and reverse the Planning Commission’s approval can be made. Such findings would comprise the inverse, or negative findings under HMC Section 20.28.165. Instead, the Project, including as modified by the Applicant’s September 28, 2026 submittal for the ten affordable housing units, and incorporating the Planning Commission’s August 11, 2026 findings by reference, would be consistent with HMC Section 20.28.165 as follows:

1. The proposed location and operation of the conditional use is in accord with the Healdsburg general plan and any applicable planned development, specific or area plan.

The proposed Project is consistent with the anticipated uses identified in the General Plan and allowable density through the application of a density bonus under State Density Bonus Law, as well as all applicable General Plan policies including:

• Housing Element Policy 5.7 Encourage senior housing development, rehabilitation, and preservation, particularly in neighborhoods that are accessible to public transit, commercial services, healthcare, and community facilities (the Project will provide 67 senior housing units within walking distance to several commercial uses, the Foss Creek walking trail, and the First & Mason St. bus stop).

Item 7.a
204 of 1062
• General Plan Policy ED-C-1 Promote housing that is affordable to workers who are vital to the community (the Project provides much-needed affordable housing within walking distance of the senior housing facility, which could be occupied by Project employees).
• Housing Program 5 – Developing Housing Affordable to Very Low, Low, Moderate, and Middle-Income Households. Employer-Provided Housing. Consider options for creating, in partnership with local employers, employer-provided or subsidized housing for local workers, including teachers, public safety employees, medical staff, etc. (the Project provides much-needed affordable housing within walking distance of the senior housing facility, designed to be convenient for Project employees).

The proposed Project is subject to the Central Healdsburg Avenue Plan. The proposed Project has been found to be consistent with the Central Healdsburg Avenue Plan through application of the incentives/concessions and waivers available to it through State Density Bonus Law.

2. The proposed location and operation of the conditional use is consistent with the applicable development standards of the Land Use Code.

The Conditional Use Permit pertains to the Residential Care, General use, defined as “a State-licensed facility, place or structure that is maintained and operated to provide nonmedical residential care, day treatment or foster agency services for seven or more adults and/or children as defined in the California health and Safety Code. This use includes the administration of limited medical assistance (e.g., dispensing of prescribed medications).” Residential Care, General, is a conditionally permitted use within the Mixed-Use and R-1-6,000 zoning designations.

The proposed Project is consistent with the development standards of the zoning districts general development standards set forth in the Land Use Code and CHAP, except as modified by Density Bonus incentives/concessions and waivers.

3. The proposed location of the conditional use and the conditions under which it would be operated and maintained will not be detrimental to public health and safety or materially injurious to uses, properties or improvements in the vicinity.

The Project type is anticipated and conditionally permitted, and will be required to comply with all local, state and federal laws, as well as the Conditions of Approval. There is no evidence in the record to establish that the use will have a detrimental effect on the public health and safety or be materially injurious to uses, properties or improvements in the vicinity.

Density Bonus
Based on the evidence in the record, none of the findings required to modify the approved Density Bonus can be made. Such findings would comprise the inverse, or negative findings under HMC Section 20.20.035. Instead, the Project, including as modified by the Applicant’s September 28, Item 7.a
205 of 1062
2026 submittal pertaining to the ten affordable housing units, and incorporating the Planning Commission’s August 11, 2026 findings by reference, would be consistent with HMC Section

20.20.035 as follows:

1. The housing development provides the housing required by State Density Bonus Law to be eligible for a density bonus and any incentives, parking reduction, or waivers requested, including housing required to replace units rented or formerly rented to very low- and low-income households as required by Government Code Section 65915(c)(3).

State Density Bonus Law requires a city to grant a density bonus to an applicant that seeks and agrees to construct a housing development, excluding any bonus units, that contains at least 5% of the total units for rent or sale to very low income households. (Gov. Code § 65915(b)(1)(B).) The Project site is a split zoned parcel with zoning designations located in both Mixed Use and R-1-6,000 located within the Mixed Use (MU) and Medium Density Residential (MR) General Plan Land Use Designations, respectively.

The Mixed Use portion of the site allows for a maximum of 16 units per acre, while the Medium Density Residential portion of the site allows for a maximum of 6 units per acre.

Based upon the project site size of 3.61 acres, the maximum number of allowed units on the site is 51 units as follows:

3.61 Acre Parcel (Per Tentative Map and Zoning Map)
.67 acres MR @ 6 units/acre = 4.02 units

2.94 acres MU @ 16 units/acre = 47.04 units
Total Units = 51.06 units, which per General Plan rounds down to 51 units.

The Project seeks a 50% state density bonus. To be eligible for a 50% density bonus, the Project must provide at least 15% of the base units as Very Low Income (VLI) units (30- 50% AMI). (Gov. Code § 65915(f)(2).) The Project proposes eight VLI units, which is

15.7% of 51, thereby qualifying for the 50% density bonus.

The density bonus calculation is as follows:
51 base units
x 50% density bonus = 25.5 units per SDBL rounds to 26
= 77 total units
The Project proposes 77 units (67 senior living + 8 VLI + 2 Low-to-moderate affordable rental units) and as such would conform to State Density Bonus law.

2. If applicable, the housing development provides the housing required by State Density Bonus Law to be eligible for an additional density bonus under Government Code Section 65915(v)(1).

The Project is not seeking an additional density bonus under Government Code Section 65915(v)(1).

Item 7.a
206 of 1062

3. If an incentive is requested, reasonable documentation has been presented showing that any requested incentive will result in identifiable and actual cost reductions to provide for affordable housing or costs or rents; except that, if a mixed-use development is requested, the application must instead meet all of the requirements of Government Code Section 65915(k)(2).

The Project is entitled to three incentives and has demonstrated that the requested incentives would result in identifiable and actual cost reductions. There is nothing in the record to indicate that the requested incentives would not do so.

4. If a waiver is requested, the development standards for which a waiver is requested would have the effect of physically precluding the construction of the housing development as designed at the densities and/or with the incentives permitted under State Density Bonus Law.

The Project is entitled to unlimited waivers, and has demonstrated that the development standards for which a waiver is requested would have the effect of physically precluding the construction of the housing development as designed at the densities and/or with the incentives permitted. There is nothing in the record to indicate that the Project could be built as designed without the requested waivers.

5. The housing development is eligible for any requested parking reductions under Government Code Section 65915(p) or other statute.

The Project is not seeking any parking reductions.

6. If the density bonus is based all or in part on donation of land, the requirements of Government Code Section 65915(g) have been met.

The Density Bonus is not based on the donation of land.

7. If the density bonus or incentive is based all or in part on the inclusion of a child care facility or condominium conversion, the requirements included in Government Code Section 65915(h) or 65915.5, as appropriate, have been met.

The Density Bonus is not based on inclusion of a child care facility or condo conversion.

8. The decision-making body shall grant requested incentive(s) unless it makes a written finding, based upon substantial evidence, of any of the following:
• The proposed incentive does not result in identifiable and actual cost reductions to provide for affordable housing costs, as defined in Health and Safety Code Section 50052.5; or for affordable rents, as defined in Health and Safety Code Section 50053; or The proposed density bonus and related incentives are directly connected to, and facilitate, the provision of the Project’s affordable housing units. The incentives provide identifiable and actual economic value to the Project by permitting additional Item 7.a
207 of 1062
residential development in exchange for the provision of qualifying affordable units.

There is nothing in the record that indicates the incentives would not result in such benefits.
• The proposed incentive would be contrary to state or federal law; or RCFE’s are considered “senior citizen housing developments” and subject to State Density Bonus Law pursuant to Government Code Section 65915(b)(1)(C). The Project qualifies as a housing development project under State law, and the Project complies with the applicable objective standards of the City’s Municipal Code, as modified by the State Density Bonus Law. There is nothing in the record that indicates the requested incentives would be contrary to state or federal law.
• The proposed incentive would have a specific, adverse impact upon the public health or safety or on any real property that is listed in the California Register of Historic Resources, and there is no feasible method to satisfactorily mitigate or avoid the specific adverse impact without rendering the housing development unaffordable to low- and moderateincome households. For the purpose of this subsection, "specific, adverse impact" means a significant, quantifiable, direct and unavoidable impact, based on objective, identified, written public health or safety standards, policies, or conditions as they existed on the date that the application for the housing development was deemed complete as defined in Government Code Section 65589.5.

The record does not identify any specific, adverse impact resulting from the proposed incentives. In particular, neither staff nor the Planning Commission identified any written, objective health or safety standard with which the Project conflicts. The Project was found to comply with applicable objective development standards, including height and setback requirements through the application of Density Bonus incentives and waivers.

The record likewise does not identify any specific, adverse impact upon real property listed in the California Register of Historical Resources. Accordingly, there is no identified significant, quantifiable, direct, and unavoidable impact upon public health or safety or upon a California Register historical resource that would preclude approval of the proposed incentives.

9. The decision-making body shall grant the waiver of development standards requested by the applicant unless it makes a written finding, based upon substantial evidence, of any of the following:
• The proposed waiver would be contrary to state or federal law; or RCFE’s are considered “senior citizen housing developments” and subject to State Density Bonus Law pursuant to Government Code Section 65915(b)(1)(C). The Project qualifies as a housing development project under State law, and the Project complies with the applicable objective standards of the City’s Municipal Code, as Item 7.a
208 of 1062
modified by the State Density Bonus Law. The proposed affordable units comply with State housing law and AFFH requirements by providing housing units affordable to lo and very low income residents. There is nothing in the record that indicates the requested waivers would be contrary to state or federal law. • The proposed waiver would have an adverse impact on any real property listed in the California Register of Historic Resources; or
The record does not identify any specific, adverse impact upon real property listed in the California Register of Historical Resources. Accordingly, there is no identified significant, quantifiable, direct, and unavoidable impact upon public health or safety or upon a California Register historical resource that would preclude approval of the proposed waivers.
• The proposed waiver would have a specific, adverse impact upon the public health or safety, and there is no feasible method to satisfactorily mitigate or avoid the specific adverse impact without rendering the housing development unaffordable to low- and moderate-income households. For the purpose of this subsection, "specific, adverse impact" means a significant, quantifiable, direct and unavoidable impact, based on objective, identified, written public health or safety standards, policies, or conditions as they existed on the date that the application for the housing development was deemed complete as defined in Government Code Section 65589.5.

The record does not identify any specific, adverse impact resulting from the proposed waivers. In particular, neither staff nor the Planning Commission identified any written, objective health or safety standard with which the Project conflicts. The Project was found to comply with applicable objective development standards, including height and setback requirements through the application of Density Bonus incentives and waivers.

In addition, the larger affordable unit size proposed by the Applicant’s September 28, 2026 submittal would utilize the same waiver as approved by the Planning Commission, but would more closely align with the City’s Inclusionary Housing Ordinance by providing units more comparable in size and bedrooms to the market rate units.

HAA Findings
Pursuant to State Density Bonus Law and the Housing Accountability Act (HAA), local jurisdictions are prohibited from disapproving density bonus affordable housing projects or conditioning them in such a way as to render them infeasible, unless the project would have a specific, adverse impact upon the public health or safety, and there is no feasible method to satisfactorily mitigate or avoid the specific, adverse impact without rendering the development unaffordable to low- and moderate-income households. The Project is a housing development project subject to the protections of State housing law. The record indicates that the Project complies with applicable objective development standards, as modified by State Density Bonus Item 7.a
209 of 1062
Law, and that neither staff nor the Planning Commission have identified a written, objective health or safety standard with which the Project conflicts.

Design Review and Tentative Map Findings
Staff has reviewed the proposed modifications to allow for larger affordable units, based on the plans date-stamped September 28, 2026. The proposed modifications result in larger affordable units (700 sf), each with one bedroom, 1.5 baths. The modifications require increasing the height of the proposed affordable housing buildings to approximately 33 feet, which is still below the 40 foot height limit allowed in the MU zone. The modifications propose no other changes to the Project, and do not require changes to the Design Review or Tentative Map findings made by the Planning Commission as they do not change the affordable unit buildings’ footprints, onsite parking, number of units, colors, materials, setbacks or overall scale, nor do they result in any inconsistency with any applicable objective standard.

ALTERNATIVES:

1. Adopt a Resolution denying the Appeal and affirming the Planning Commission’s approval of Conditional Use Permit application (CUP-0001-2026) and density bonus.

2. Modify the Planning Commission’s approval of the Project.

3. Reverse the Planning Commission’s approval of Conditional Use Permit application (CUP0001-2026) and density bonus. Council will need to provide findings to support reversing the approval and Staff will return at a future date with a resolution.

FISCAL IMPACT:

The project is privately funded and requires no use of public funds.

ENVIRONMENTAL ANALYSIS:

Pursuant to the provisions of CEQA and the CEQA Guidelines, the Project, including as modified by the Applicant’s September 28, 2026 submittal pertaining to the ten affordable housing units, is exempt from CEQA based on the following:

A. The Project, including as modified by the Applicant’s September 28, 2026 submittal pertaining to the ten affordable housing units, qualifies for a Class 32 categorical exemption under the California Environmental Quality Act Guidelines Section 15332, In-Fill Development Projects, in that the proposed buildings and associated site improvements meet the following conditions contained in the Class 32 In-Fill Exemption:

• The Project, including as modified, is consistent with the applicable general plan designation and all applicable general plan policies as well as the applicable zoning designation and regulations.

The proposed Project, including as modified by the Applicant’s September 28, 2026 submittal pertaining to the ten affordable housing units, is located on a split-zoned site within the Mixed Use (MU) and Medium Density Residential General Plan Land Use designation and the Mixed Use (MU) and R-1-6,000 Zoning Districts. The proposed Project, including as modified, is a conditionally permitted use within the MU zone and a permitted use within the R-1-6,000 zoning district, and the proposed buildings and site Item 7.a
210 of 1062
improvements are consistent with the development standards of the zoning district and are consistent with the development standards of the zoning district and general development standards set forth in the Land Use Code except as modified by Density Bonus incentives and waivers. The courts have determined modifications required by the Density Bonus Law do not disqualify the Project from claiming the exemption.

• The proposed development occurs within the City limits on a project site of no more than five acres substantially surrounded by urban uses.

The subject site is 3.61 acres, located within the city limits of the City of Healdsburg, and is adjacent to urban uses on three sides.
• The Project site has no value as habitat for endangered, rare or threatened species.

The Project site is a currently fully developed, paved site with existing commercial buildings and provides no value as habitat for endangered, rare, or threatened species. • Approval of the Project would not result any significant effects relating to traffic, noise, air quality, or water quality.

Traffic: Small infill projects located in the downtown area have been pre-screened and determined to result in less than 15% or below the countywide average for Vehicle Miles Traveled (VMT) per capita if the project is consistent with the General Plan Land Use designation. The Project is located within the pre-screened area and is exempt from any further traffic analysis. In addition, a Traffic Impact Study was prepared and showed a reduction in the number of trips generated by the proposed use over the previous use as a lumber yard. An update to the Traffic Impact Study was submitted to show that the proposed modifications to the affordable units would not result in any additional trips, and therefore would not result in any new or more significant impacts.

Noise: The Project-specific Noise Impact Analysis concluded that the proposed Project would result in less-than-significant noise and vibration impacts. Construction noise would comply with the City of Healdsburg Municipal Code by occurring only during permitted hours and incorporating project design features such as temporary 7-foot-high sound barriers, properly maintained equipment, and a designated disturbance coordinator.

Construction noise at the nearest residence is projected to meet the Federal Transit Administration (FTA) criterion of 80 dBA Leq (8-hour). Operational noise, including from mechanical equipment, pool equipment, Project operations and Project-generated traffic would remain below the City's noise standards, and construction and operational vibration levels would also remain below applicable FTA thresholds. The Project is not located within an airport noise compatibility area and would not expose residents or workers to excessive aircraft noise. Accordingly, no significant noise impacts are anticipated. An update to the Noise Impact Analysis confirmed that the proposed modifications to the affordable units would not result in any new or increased noise impacts.

Item 7.a
211 of 1062
Air Quality: The Project-specific Air Quality Analysis concluded that the proposed Project would result in less-than-significant air quality impacts. Construction-related fugitive dust would be minimized through implementation of required Best Management Practices (BMPs) pursuant to General Plan Policy NR-28, and construction exhaust emissions would remain below Bay Area Air District significance thresholds for reactive organic gases (ROG), nitrogen oxides (NOx), particulate matter (PM10), and fine particulate matter (PM2.5). A construction Health Risk Assessment also determined that diesel particulate matter (DPM) cancer risk, chronic non-cancer hazard, and PM2.5 concentrations at nearby sensitive receptors, including adjacent residences and a nearby preschool, would remain below Bay Area Air District significance thresholds. Operational impacts would likewise be less than significant because the residential project would not include substantial sources of toxic air contaminants or diesel truck traffic. Accordingly, the Project would not result in significant construction or operational air quality impacts. An update to the Air Quality Analysis confirmed that the proposed modifications to the affordable units would not result in any new or increased air quality impacts.

Water Quality: The Project will be required to install post construction stormwater treatment best management practices (BMP) in accordance with the current version of the Low Impact Development (LID) Technical Design Manual. A Final Stormwater Management Plan will be required to be submitted with the building permit plans for the site. The proposed modifications to the affordable units do not increase the building footprints or alter amount of pervious or impervious surfaces of the Project. No new or additional impacts to water quality would occur.

• The site can be adequately served by all required utilities and public services.

The Project site is located within the City of Healdsburg urban service area and can be adequately served by the City’s water and sewer systems. Electric is provided by the City of Healdsburg Utilities. Natural gas is provided to the site by Pacific Gas and Electric.

The City of Healdsburg provides Fire and Police services for the site. The proposed modifications to the affordable units do not change the number of units and would not affect the ability of the Project to be adequately served by required utilities and public services.

B. Further, none of the exceptions listed in CEQA Guidelines Section 15300.2 apply, as described below:
• Location (§ 15300.2(a)): There is no evidence in the record that the Project will impact an environmental resource of hazardous or critical concern in an area designated, precisely mapped, and officially adopted pursuant to law by federal, State, or local agencies. The Project site is located within a substantially developed neighborhood and is not located in a sensitive environmental area. Therefore, the “location” exception is not applicable.
• Cumulative Impacts (§ 15300.2(b)): There is no evidence in the record that successive projects of the same type in the area would have a cumulatively significant Item 7.a
212 of 1062
environmental impact. The Project proposes a senior residential care facility and affordable housing, in accordance with the Land Use Code and General Plan, within a substantially developed neighborhood. Staff is aware of no evidence of impending development of other similar projects in the area that would have a significant impact on the environment, either alone or cumulatively with other projects in the vicinity. The proposed modifications to the affordable units would not change this conclusion, as the modifications do not change the number of units and only result in a modest increase in square footage.
• Unusual Circumstances (§ 15300.2(c)): There is no evidence in the record that the Project (1) involves unusual circumstances or (2) may have a significant effect on the environment due to those unusual circumstances. Furthermore, there is no evidence in the record that the Project will have a significant adverse impact on the environment.

The Project does not differ from the general circumstances of the projects covered by the Class 32 categorical exemption and the Project does not create an environmental risk that does not exist for the general class of exempt projects. As discussed above and in the Staff Reports, the Project is consistent with the General Plan and all applicable General Plan policies as well as with applicable zoning designation and regulations, the Project occurs within City limits on a project site of no more than five acres substantially surrounded by urban uses, the Project site has no value as habitat for endangered, rare or threatened species, approval of the Project would not result in any significant effects relating to traffic, noise, air quality, or water quality, and the Project site can be adequately served by all required utilities and public services. The Project site is zoned and designated for the Project’s proposed uses, and the Project complies with all applicable objective zoning standards with the application of State Density Bonus Law. The Project, including as modified, is consistent with the scale and intensity anticipated for senior and affordable housing developments in the City as allowed for and required by State Density Bonus Law, such that the height, FAR, ground coverage, etc. of the Project cannot be considered “unusual.” As such, there are no identifiable unusual circumstances and no evidence that the Project, including as modified, may have a significant effect on the environment due to those unusual circumstances. There is also no evidence in the record that the Project, including as modified, will have a significant adverse impact on the environment. Therefore, the “unusual circumstances” exception does not apply.
• Scenic Highways, Hazardous Waste Sites, Historical Resources (§ 15300.2(d)-(f)): The Project is not proposed near a designated scenic highway, does not involve a current or former hazardous waste site, and does not affect any historical resources. Therefore, the exceptions in subsections (d) through (f) are not applicable to this Project.

Accordingly, there is no substantial evidence in the record establishing that any §15300.2 exception precludes reliance on the categorical exemption. Because substantial evidence in the record shows that the Project, including as modified, is consistent with the requirements of a Class 32 exemption, and none of the exceptions to applying a categorical exemption in CEQA Guidelines Section 15300.2 apply, the City Council finds that the Project is categorically exempt from CEQA.

(“State Density Bonus Law”); and WHEREAS, on June 3, 2026, City staff determined the Project application to be complete.

WHEREAS, on July 4, 2026, the Project was deemed consistent with applicable standards pursuant to the Housing Accountability Act.

WHEREAS, on August 11, 2026, the Planning Commission conducted a duly noticed public hearing and voted 5 to 0 to adopt Resolution 2026-07 approving the Project and all associated entitlements, including the Density Bonus, and finding the Project exempt from the California Environmental Quality Act (“CEQA”); and
WHEREAS, on August 20, 2026, two residents (“Appellants”) filed an appeal (“Appeal”) of the Planning Commission’s decisions on the CUP and Density Bonus, and requested the City Council reverse the CUP approval and modify the granting of the Density Bonus to require a marketing plan before approval; and
WHEREAS, the City provided public notice of this Appeal hearing to all owners within 300 feet of the Project site, and published notice in the Healdsburg Tribune, and on the Project site consistent with HMC Section 20.28.085; and
Item 7.a
215 of 1062
WHEREAS, on September 28, 2026, the Applicant submitted updated Project plans (“Modified Plans”) that show larger affordable units in response to concerns raised by City staff, as well as the Planning Commission and members of the public. The proposed changes increase the size of the affordable housing units from approximately 380 square feet to approximately 700 square feet, and will comprise all one-bedroom units with 1.5 baths per unit. The proposed changes would not alter the buildings’ footprint, the number of affordable units or their affordability levels, or otherwise change the senior living facility component of the Project; and WHEREAS, in addition to the Modified Plans, Applicant submitted updated documentation from its CEQA consultants demonstrating that the Modified Plans would not result in new or more significant environmental impacts or otherwise require changes to the CEQA determination; and
WHEREAS, the City Council has reviewed the Modified Plans and determined that they do not require modifications to the Project’s approval findings or CEQA determination; and WHEREAS, throughout this document, all references to the Project shall include the Project as subject to the Modified Plans; and
WHEREAS, on October 5, 2026, the City Council conducted a duly noticed public hearing on the Appeal, consistent with Land Use Code Section 20.28.085 at which time it considered the record and all oral and documentary evidence presented and incorporated all testimony and documents into the record by reference; and
WHEREAS, the City Council has reviewed the points of the Appeal and has determined it will uphold the Planning Commission decision to approve the Project; and NOW, THEREFORE, BE IT RESOLVED, by the City Council of the City of Healdsburg as follows:

1. The above recitals are true and correct and material to this Resolution.

2. In making its findings, the City Council relied upon and hereby incorporates by reference all correspondence, testimony, staff reports, and other related materials from the Planning Commission’s public hearing and the Appeal hearing and hereby incorporates the evidence and findings stated in Planning Commission Resolution 2026-07 and the associated Planning Commission and City Council staff reports as a basis for the adoption of this Resolution.

BE IT FURTHER RESOLVED, the City Council of the City of Healdsburg hereby denies Appeal APPL 0001-2025 and affirms the Planning Commission’s approval of CUP 0001-2026, subject to conditions, as modified, for the construction of the Project, and makes the following findings pertaining to its denial of the Appeal:

Appeal Issue No. 1
“The Hudson is not a conditionally permitted use under the applicable zoning ordinances.” Item 7.a
216 of 1062
Finding:

The Project is a conditionally permitted use under the City’s Land Use Code. The Land Use Code expressly permits “residential care, general” uses with a Conditional Use Permit (CUP) in the MU zone and as an allowed use in the R-1-6,000 zone. That use is defined as a State-licensed facility providing “nonmedical residential care, day treatment or foster agency services for seven or more adults and/or children,” including “the administration of limited medical assistance (e.g., dispensing of prescribed medications).” (HMC § 20.28.310.) The Project, which includes 67 senior living units with access to memory care, residential and recreational amenities, falls squarely within this definition. The Applicant has confirmed that the Project will provide housing and residential services, not skilled nursing or medical care beyond limited medical assistance.

The Project's RCFE and memory care components do not constitute a prohibited nursing-home or medical use. Memory care involves assistance with day-to-day tasks and does not require professional medical care. Likewise, the on-site medical suite and periodic residential assessments do not alter the Project's zoning classification: the record shows the medical suite will not be staffed by Project personnel but will instead be available for residents to receive occasional visits from their own personal medical providers, and the assessments serve to ensure that any resident who does require skilled nursing or medical care is appropriately transferred to a facility capable of providing it.

Nothing in the record, apart from opinion, indicates any use beyond “residential care, general.” The Project employs the same use type designation as the Enso Village senior living project and has been treated and processed consistently with that precedent.

The City Council therefore finds that the Project is consistent with the City's Land Use Code and was appropriately approved by the Planning Commission.

Appeal Issue No. 2
“The Hudson’s Density Bonus application is insufficient because it lacks a marketing plan.” Finding:

The absence of a marketing plan did not make the density bonus application insufficient or prevent approval. Although the Healdsburg Land Use Code calls for a marketing plan, state Density Bonus Law prohibits the City from making such an additional submission a prerequisite to reviewing or approving a density bonus. Consistent with this, the City’s published application checklist omits this requirement. The City has nevertheless addressed the substance of the requirement through Condition of Approval No. 24, which requires the applicant to submit a marketing plan, along with an approved affordable housing agreement, which will be recorded and run with land, before issuance of the first Certificate of Occupancy.

The City Council therefore finds that the Planning Commission correctly approved the density bonus without a marketing plan.

BE IT FURTHER RESOLVED that the City Council of the City of Healdsburg finds that none of the inverse or negative findings under HMC Section 20.28.165 can be made with respect Item 7.a
217 of 1062
to the CUP, and, incorporating the Planning Commission’s August 11, 2026 findings by reference, further finds the Project consistent with the HMC as follows:

1. That the proposed location and operation of the conditional use is in accord with the Healdsburg general plan and any applicable planned development, specific or area plan.

The proposed Project is consistent with the anticipated uses identified in the General Plan and allowable density through the application of a density bonus under State Density Bonus Law, as well as all applicable General Plan policies including:
• Housing Element Policy 5.7 Encourage senior housing development, rehabilitation, and preservation, particularly in neighborhoods that are accessible to public transit, commercial services, healthcare, and community facilities (the Project will provide 67 senior housing units within walking distance to several commercial uses, the Foss Creek walking trail, and the First & Mason St bus stop).
• General Plan Policy ED-C-1 Promote housing that is affordable to workers who are vital to the community (the Project provides much-needed affordable housing within walking distance of the senior housing facility, which could be occupied by Project employees).
• Housing Program 5 – Developing Housing Affordable to Very Low, Low, Moderate, and Middle-Income Households. Employer-Provided Housing. Consider options for creating, in partnership with local employers, employer-provided or subsidized housing for local workers, including teachers, public safety employees, medical staff, etc. (the Project provides much-needed affordable housing within walking distance of the senior housing facility, designed to be convenience for Project employees).

The proposed Project is subject to the Central Healdsburg Avenue Plan. The proposed Project has been found to be consistent with the Central Healdsburg Avenue Plan through application of the incentives/concessions and waivers available to it through State Density Bonus Law.

2. The proposed location and operation of the conditional use is consistent with the applicable development standards of the Land Use Code.

The Conditional Use Permit pertains to the use as Residential Care, General, defined as “a State-licensed facility, place or structure that is maintained and operated to provide nonmedical residential care, day treatment or foster agency services for seven or more adults and/or children as defined in the California health and Safety Code. This use includes the administration of limited medical assistance (e.g., dispensing of prescribed medications).” Residential Care, General, is a conditionally permitted use within the Mixed-Use zoning designation and a permitted use in the R-1-6000 zoning designation.

The proposed Project is consistent with the development standards of the zoning districts’ general development standards set forth in the Land Use Code and CHAP, except as Item 7.a
218 of 1062
modified by Density Bonus incentives/concessions and waivers.

3. The proposed location of the conditional use and the conditions under which it would be operated and maintained will not be detrimental to public health and safety or materially injurious to uses, properties or improvements in the vicinity.

The Project type is anticipated and conditionally permitted, and will be required to comply with all local, state and federal laws, as well as the Conditions of Approval. There is no evidence in the record to establish that the use will have a detrimental effect on the public health and safety or materially injurious to uses, properties or improvements in the vicinity.

BE IT FURTHER RESOLVED that City Council of the City of Healdsburg finds that none of the inverse or negative findings under HMC Section 20.20.035(D) can be made with respect to the Density Bonus, and, incorporating the Planning Commission’s August 11, 2026 findings by reference, further finds the Project consistent with the HMC as follows:
a. The housing development provides the housing required by State Density Bonus Law to be eligible for a density bonus and any incentives, parking reduction, or waivers requested, including housing required to replace units rented or formerly rented to very low- and low-income households as required by Government Code Section 65915(c)(3).

State Density Bonus Law requires a city to grant a density bonus to an applicant that seeks and agrees to construct a housing development, excluding any bonus units, that contains at least 5% of the total units for rent or sale to very low income households. (Gov. Code § 65915(b)(1)(B).) The Project site is a split zoned parcel with zoning designations located in both Mixed Use and R-1-6,000 located within the Mixed Use (MU) and Medium Density Residential (MR) General Plan Land Use Designations, respectively.

The Mixed Use portion of the site allows for a maximum of 16 units per acre, while the Medium Density Residential portion of the site allows for a maximum of 6 units per acre.

Based upon the project site size of 3.61 acres, the maximum number of allowed units on the site is 51 units as follows:

3.61 Acre Parcel
.67 acres MR @ 6 units/acre = 4.02 units

2.94 acres MU @ 16 units/acre = 47.04 units
Total Units = 51.06 units, which per General Plan rounds down to 51 units.

The Project seeks a 50% state density bonus. To be eligible for a 50% density bonus, the Project must provide at least 15% of the base units as Very Low Income (VLI) units (30- 50% AMI). (Gov. Code § 65915(f)(2).) The Project proposes eight VLI units, which is

15.7% of 51, thereby qualifying for the 50% density bonus.

Item 7.a
219 of 1062
The density bonus calculation is as follows:
51 base units
x 50% density bonus = 25.5 units per SDBL rounds to 26
= 77 total units
The Project proposes 77 units (67 senior living + 8 VLI + 2 Low-to-moderate affordable rental units) and as such would conform to State Density Bonus law. There is nothing in the record that indicates that the Project would not conform. b. If applicable, the housing development provides the housing required by State Density Bonus Law to be eligible for an additional density bonus under Government Code Section 65915(v)(1).

The Project is not seeking an additional density bonus under Government Code Section 65915(v)(1).
c. If an incentive is requested, reasonable documentation has been presented showing that any requested incentive will result in identifiable and actual cost reductions to provide for affordable housing or costs or rents; except that, if a mixed-use development is requested, the application must instead meet all of the requirements of Government Code Section 65915(k)(2).

The Project is entitled to three incentives, and has demonstrated that the requested incentives would result in identifiable and actual cost reductions. There is nothing in the record to indicate that the requested incentives would not do so. d. If a waiver is requested, the development standards for which a waiver is requested that would have the effect of physically precluding the construction of the housing development as designed at the densities and/or with the incentives permitted under State Density Bonus Law.

The Project is entitled to unlimited waivers, and has demonstrated that the development standards for which a waiver is requested that would have the effect of physically precluding the construction of the housing development as designed at the densities and/or with the incentives permitted. There is nothing in the record to indicate that the Project could be built as designed without the requested waivers. e. The housing development is eligible for any requested parking reductions under Government Code Section 65915(p) or other statute.

The Project is not seeking any parking reductions.
f. If the density bonus is based all or in part on donation of land, the requirements of Government Code Section 65915(g) have been met.

The Density Bonus is not based on the donation of land. g. If the density bonus or incentive is based all or in part on the inclusion of a child care facility or condominium conversion, the requirements included in Government Code Section 65915(h) or Item 7.a
220 of 1062
65915.5, as appropriate, have been met.

The Density Bonus is not based on inclusion of a child care facility or condo conversion. h. The decision-making body shall grant requested incentive(s) unless it makes a written finding, based upon substantial evidence, of any of the following:
• The proposed incentive does not result in identifiable and actual cost reductions to provide for affordable housing costs, as defined in Health and Safety Code Section 50052.5; or for affordable rents, as defined in Health and Safety Code Section 50053; or
The proposed density bonus and related incentives are directly connected to, and facilitate, the provision of the Project’s affordable housing units. The incentives provide identifiable and actual economic value to the Project by permitting additional residential development in exchange for the provision of qualifying affordable units.

There is nothing in the record that indicates the incentives would not result in such benefits.
• The proposed incentive would be contrary to state or federal law; or RCFE’s are considered “senior citizen housing developments” and subject to State Density Bonus Law pursuant to Government Code Section 65915(b)(1)(C). The Project qualifies as a housing development project under State law, and the Project complies with the applicable objective standards of the City’s Municipal Code, as modified by the State Density Bonus Law. There is nothing in the record that indicates the requested incentives would be contrary to state or federal law.
• The proposed incentive would have a specific, adverse impact upon the public health or safety or on any real property that is listed in the California Register of Historic Resources, and there is no feasible method to satisfactorily mitigate or avoid the specific adverse impact without rendering the housing development unaffordable to low- and moderate-income households. For the purpose of this subsection, "specific, adverse impact" means a significant, quantifiable, direct and unavoidable impact, based on objective, identified, written public health or safety standards, policies, or conditions as they existed on the date that the application for the housing development was deemed complete as defined in Government Code Section 65589.5.

The record does not identify any specific, adverse impact resulting from the proposed incentives. In particular, neither staff nor the Planning Commission identified any written, objective health or safety standard with which the Project conflicts. The Project was found to comply with applicable objective development standards, including height and setback requirements through the application of Density Bonus incentives and waivers.

The record likewise does not identify any specific, adverse impact upon real property Item 7.a
221 of 1062
listed in the California Register of Historical Resources. Accordingly, there is no identified significant, quantifiable, direct, and unavoidable impact upon public health or safety or upon a California Register historical resource that would preclude approval of the proposed incentives.
i. The decision-making body shall grant the waiver of development standards requested by the applicant unless it makes a written finding, based upon substantial evidence, of any of the following:
• The proposed waiver would be contrary to state or federal law; or RCFE’s are considered “senior citizen housing developments” and subject to State Density Bonus Law pursuant to Government Code Section 65915(b)(1)(C). The Project qualifies as a housing development project under State law, and the Project complies with the applicable objective standards of the City’s Municipal Code, as modified by the State Density Bonus Law. There is nothing in the record that indicates the requested waivers would be contrary to state or federal law.
• The proposed waiver would have an adverse impact on any real property listed in the California Register of Historic Resources; or
The record does not identify any specific, adverse impact upon real property listed in the California Register of Historical Resources. Accordingly, there is no identified significant, quantifiable, direct, and unavoidable impact upon public health or safety or upon a California Register historical resource that would preclude approval of the proposed waivers.
• The proposed waiver would have a specific, adverse impact upon the public health or safety, and there is no feasible method to satisfactorily mitigate or avoid the specific adverse impact without rendering the housing development unaffordable to low- and moderate-income households. For the purpose of this subsection, "specific, adverse impact" means a significant, quantifiable, direct and unavoidable impact, based on objective, identified, written public health or safety standards, policies, or conditions as they existed on the date that the application for the housing development was deemed complete as defined in Government Code Section 65589.5.

The record does not identify any specific, adverse impact resulting from the proposed waivers. In particular, neither staff nor the Planning Commission identified any written, objective health or safety standard with which the Project conflicts. The Project was found to comply with applicable objective development standards, including height and setback requirements through the application of Density Bonus incentives and waivers.

In addition, the larger affordable unit size proposed by Modified Plans would utilize the same waiver as approved by the Planning Commission but would more closely align with the City’s Inclusionary Housing Ordinance by providing units more comparable Item 7.a
222 of 1062
in size and bedrooms to the market rate units.

BE IT FURTHER RESOLVED, by the City Council of the City of Healdsburg, that, pursuant to State Density Bonus Law and the Housing Accountability Act (HAA), local jurisdictions are prohibited from disapproving density bonus affordable housing projects or conditioning them in such a way as to render them infeasible, unless the project would have a specific, adverse impact upon the public health or safety, and there is no feasible method to satisfactorily mitigate or avoid the specific, adverse impact without rendering the development unaffordable to low- and moderate-income households.

The City Council finds and determines that the Project is a housing development project under the HAA. The Project complies with applicable objective standards of the General Plan and Land Use Code, as modified by State Density Bonus Law. The record identifies no objective, written public health or safety standard, policy, or condition with which the Project conflicts, and does not demonstrate a specific, adverse impact as defined in Government Code § 65589.5.

BE IT FURTHER RESOLVED, by the City Council of the City of Healdsburg, that the Modified Plans have been reviewed and are found to be substantially consistent with the approved Major Design Review and Tentative Map, and no changes to the Planning Commission’s approval findings for the Major Design Review and Tentative Map made on August 11, 2026 and which are incorporated herein by reference, are required.

The Modified Plans result in larger affordable units (700 sf), each with one bedroom, 1.5 baths, which more closely matches the intent of the City’s Inclusionary Housing Ordinance, to provide affordable units comparable in size to the market rate units. The Modified Plans require increasing the height of the proposed affordable housing buildings to approximately 33 feet, which is still below the 40 foot height limit allowed in the MU zone. The modifications propose no other changes to the Project, and do not require changes to the Design Review or Tentative Map findings made by the Planning Commission as they do not change the affordable unit buildings’ footprints, onsite parking, number of units, colors, materials, setbacks or overall scale, nor do they result in any inconsistency with any applicable objective standard.

BE IT FURTHER RESOLVED, by the City Council of the City of Healdsburg, that Condition of Approval 1 shall read as follows:

The project shall be developed in accordance with the architectural and landscape plans dated July 29, 2026, including the height revision, all as approved by the Planning Commission on August 11, 2026, with the exception of the ten affordable units, which shall be developed in accordance with the plans date-stamped September 29, 2026 and approved by the City Council on October 5, 2026, except as conditioned or modified herein.

BE IT FURTHER RESOLVED, by the City Council of the City of Healdsburg, that the Project is exempt from CEQA based on the following:

A. The Project qualifies for a Class 32 categorical exemption under the California Environmental Quality Act Guidelines Section 15332, In-Fill Development Projects. The Item 7.a
223 of 1062
City Council incorporates by reference the Traffic Impact Study Addendum (Attachment 9 to the Staff Report), Supplemental Noise Memos (Attachment 8 to the Staff Report), and Supplemental Air Quality Memo (Attachment 7 to the Staff Report), and the Final Stormwater Management Plan requirements referenced below, as substantial evidence supporting the Class 32 exemption. Further, the proposed buildings and associated site improvements meet the following conditions contained in the Class 32 In-Fill Exemption:
• The Project is consistent with the applicable general plan designation and all applicable general plan policies as well as the applicable zoning designation and regulations.

The proposed Project is located on a split-zoned site within the Mixed Use (MU) and Medium Density Residential General Plan Land Use designation and the Mixed Use (MU) and R-1-6,000 Zoning Districts. The proposed Project is a conditionally permitted use within the MU zone and R-1-6,000 zoning districts, and the proposed buildings and site improvements are consistent with the development standards of the zoning district and are consistent with the development standards of the zoning district and general development standards set forth in the Land Use Code except as modified by Density Bonus incentives and waivers. The courts have determined modifications required by the Density Bonus Law do not disqualify the Project from claiming the exemption. • The proposed development occurs within the City limits on a project site of no more than five acres substantially surrounded by urban uses.

The subject site is 3.61 acres, located within the city limits of the City of Healdsburg, and is adjacent to urban uses on three sides.
• The Project site has no value as habitat for endangered, rare or threatened species.

The Project site is a currently fully developed, paved site with existing commercial buildings and provides no value as habitat for endangered, rare, or threatened species. • Approval of the Project would not result any significant effects relating to traffic, noise, air quality, or water quality.

Traffic: Small infill projects located in the downtown area have been pre-screened and determined to result in less than 15% or below the countywide average for Vehicle Miles Travelled (VMT) per capita if the project is consistent with the General Plan Land Use designation. In addition, a Traffic Impact Study was prepared and showed a reduction in the number of trips generated by the proposed use over the previous use as a lumber yard. An update to the Traffic Impact Study was submitted to show that the Modified Plans would not result in any new or more significant impacts.

Noise: The Project-specific Noise Impact Analysis concluded that the proposed Project would result in less-than-significant noise and vibration impacts.

Construction noise would comply with the City of Healdsburg Municipal Code by occurring only during permitted hours and incorporating project design features Item 7.a
224 of 1062
such as temporary 7-foot-high sound barriers, properly maintained equipment, and a designated disturbance coordinator. Construction noise at the nearest residence is projected to meet the Federal Transit Administration (FTA) criterion of 80 dBA Leq (8-hour). Operational noise, including from mechanical equipment, pool equipment, Project operations and Project-generated traffic would remain below the City's noise standards, and construction and operational vibration levels would also remain below applicable FTA thresholds. The Project is not located within an airport noise compatibility area and would not expose residents or workers to excessive aircraft noise. Accordingly, no significant noise impacts are anticipated.

An update to the Noise Impact Analysis confirmed that the Modified Plans would not result in any new or increased noise impacts.

Air Quality: The Project-specific Air Quality Analysis concluded that the proposed Project would result in less-than-significant air quality impacts. Constructionrelated fugitive dust would be minimized through implementation of required Best Management Practices (BMPs) pursuant to General Plan Policy NR-28, and construction exhaust emissions would remain below Bay Area Air District significance thresholds for reactive organic gases (ROG), nitrogen oxides (NOx), particulate matter (PM10), and fine particulate matter (PM2.5). A construction Health Risk Assessment also determined that diesel particulate matter (DPM) cancer risk, chronic non-cancer hazard, and PM2.5 concentrations at nearby sensitive receptors, including adjacent residences and a nearby preschool, would remain below Bay Area Air District significance thresholds. Operational impacts would likewise be less than significant because the residential project would not include substantial sources of toxic air contaminants or diesel truck traffic.

Accordingly, the Project would not result in significant construction or operational air quality impacts. An update to the Air Quality Analysis confirmed that the Modified Plans would not result in any new or increased air quality impacts.

Water Quality: The Project will be required to install post construction stormwater treatment best management practices (BMP) in accordance with the current version of the Low Impact Development (LID) Technical Design Manual. A Final Stormwater Management Plan will be required to be submitted with the building permit plans for the site. The Modified Plans do not increase the building footprints or alter amount of pervious or impervious surfaces of the Project. No new or additional impacts to water quality would occur.
• The site can be adequately served by all required utilities and public services.

The Project site is located within the City of Healdsburg urban service area and can be adequately served by the City’s water and sewer systems. Electric is provided by the City of Healdsburg Utilities. Natural gas is provided to the site by Pacific Gas and Electric.

The City of Healdsburg provides Fire and Police services for the site. The Modified Plans do not change the number of units and would not affect the ability of the Project to be adequately served by required utilities and public services.

Item 7.a
225 of 1062
Further, none of the exceptions listed in CEQA Guidelines Section 15300.2 apply, as described below:
• Location (§ 15300.2(a)): There is no evidence in the record that the Project will impact an environmental resource of hazardous or critical concern in an area designated, precisely mapped, and officially adopted pursuant to law by federal, State, or local agencies. The Project site is located within a substantially developed neighborhood and is not located in a sensitive environmental area. Therefore, the “location” exception is not applicable. • Cumulative Impacts (§ 15300.2(b)): There is no evidence in the record that successive projects of the same type in the area would have a cumulatively significant environmental impact. The Project proposes a senior residential care facility and affordable housing, in accordance with the Land Use Code and General Plan, within a substantially developed neighborhood. Staff is aware of no evidence of impending development of other similar projects in the area that would have a significant impact on the environment, either alone or cumulatively with other projects in the vicinity. The Modified Plans do not change this conclusion, as the modifications do not change the number of units and only result in a modest increase in square footage.
• Unusual Circumstances (§ 15300.2(c)): There is no evidence in the record that the Project (1) involves unusual circumstances or (2) may have a significant effect on the environment due to those unusual circumstances. Furthermore, there is no evidence in the record that the Project will have a significant adverse impact on the environment. The Project does not differ from the general circumstances of the projects covered by the Class 32 categorical exemption and the Project does not create an environmental risk that does not exist for the general class of exempt projects. As discussed above and in the Staff Reports, the Project is consistent with the General Plan and all applicable General Plan policies as well as with applicable zoning designation and regulations, the Project occurs within City limits on a project site of no more than five acres substantially surrounded by urban uses, the Project site has no value as habitat for endangered, rare or threatened species, approval of the Project would not result in any significant effects relating to traffic, noise, air quality, or water quality, and the Project site can be adequately served by all required utilities and public services. The Project site is zoned and designated for the Project’s proposed uses, and the Project complies with all applicable objective zoning standards with the application of State Density Bonus Law. The Project is consistent with the scale and intensity anticipated for senior housing development in the City as allowed for and required by State Density Bonus Law, such that the height, FAR, ground coverage, etc. of the Project cannot be considered “unusual.” As such, there are no identifiable unusual circumstances and no evidence that the Project may have a significant effect on the environment due to those unusual circumstances. There is also no evidence in the record that the Project will have a significant adverse impact on the environment. Therefore, the “unusual circumstances” exception does not apply.
• Scenic Highways, Hazardous Waste Sites, Historical Resources (§ 15300.2(d)-(f)): The Project is not proposed near a designated scenic highway, does not involve a current or former hazardous waste site, and does not affect any historical resources. Therefore, the Item 7.a
226 of 1062
exceptions in subsections (d) through (f) are not applicable to this Project.

Accordingly, there is no substantial evidence in the record establishing that any §15300.2 exception precludes reliance on the categorical exemption. Because substantial evidence in the record shows that the Project is consistent with the requirements of a Class 32 exemption, and none of the exceptions to applying a categorical exemption in CEQA Guidelines Section 15300.2 apply, the City Council finds that the Project is categorically exempt from CEQA.

NOW, THEREFORE, BE IT FURTHER RESOLVED that based on the aforementioned findings, the City Council of the City of Healdsburg approves the Project, subject to conditions of approval included as Exhibit A to this resolution, and finds the Project exempt from CEQA.

The project applicant shall prepare public improvement plans per city engineering design standards and requirements for all work within the public right of way and within public easements on the project site and submit an application for public improvement plans and corresponding application fee. The applicant shall enter into a public improvement agreement with the city of Healdsburg using the city approved public improvement agreement form, and provide the city required surety and insurance certificates.

52. All public improvements and private improvements within public easements shall be designed and constructed per current city standards, specifications, and requirements subject to approval by the City Engineer.

Item 7.a
232 of 1062

53. Prior to the first final inspection of any of the structures, the applicant shall pay all Public Works required development impact fees for the proposed project less existing development impact fee credits for the project site. The exact amount of all Public Works required development impact fees and existing fee credits will be calculated by Public Works as part of the building permit application for the structure. Note that there will be other development impact related fees due from other city departments.

Fire Department

54. Drive-through EVA concept acceptable; no hammerhead required. The Fire Department acknowledges the proposed drive-through emergency vehicle access (EVA) configuration in lieu of a hammerhead, subject to final apparatus maneuvering verification.

55. Fire apparatus turning-radius / Auto TURN exhibit required. Submit a turning-radius analysis demonstrating compliant ingress, on-site circulation, and egress for Healdsburg Fire apparatus. The exhibit shall verify:
• Entry from Hudson Street
• Internal circulation through fire lanes
• Maneuvering adjacent to parking lot access points and porte cochere • Use of the Mason Street emergency access (if intended for operational use) This is required to confirm that the drive-through EVA performs as intended under real operating conditions.

56. Emergency Vehicle Access (EVA) easement required. All portions of the fire apparatus access route that are not located within the public right-of-way shall be provided with a recorded emergency vehicle access easement.
• Easement shall be reviewed and approved by the Fire Department prior to recordation • Easement shall ensure permanent, unobstructed access for fire apparatus • Easement language shall prohibit obstructions, parking, or modifications that reduce required clearances

57. Mason Street emergency access – easement and gate requirements. The secondary access connection to Mason Street, identified as a gated emergency-access-only driveway, shall:
• Be located within a recorded EVA easement
• Include Fire Department–approved gate design (Knox access, emergency override, fail-safe operation)
• Maintain full required fire access width and vertical clearance at all times

58. Maintain required fire access widths. Plans indicate 20-foot fire lanes and 26-foot aerial access zones.

Final plans shall dimension and maintain these widths continuously, free of encroachments from parking, landscaping, structures, or site features.

59. Parking-lot interface and circulation conflicts. The turning-radius exhibit shall account for real-world conditions at parking lot entrances, including vehicle stacking, stall overhang, and curb geometry. Fire lanes shall remain clear and functional during peak site use.

60. Hydrant layout – additional opportunities to be evaluated. The utility plan identifies an existing hydrant and indicates new hydrant placement to be determined by the Fire Marshal. Based on the site layout, Item 7.a
233 of 1062
additional hydrant placement—particularly toward the northeast/Mason Street side—should be evaluated to improve coverage.

61. Hydrant coverage exhibit required. Provide a plan demonstrating that all portions of the buildings are within required fire department hose reach (typically 250 feet) from an approved hydrant, measured along approved access routes.

62. Fire flow and flow-test data required. Submit current hydrant flow test data and required fire-flow calculations for all structures. Water supply adequacy must be confirmed prior to approval of site design.

63. Coordinate hydrants and fire service with utility plan and easements. Final hydrant locations, underground fire service routing, and associated appurtenances shall be coordinated with:
• Existing and proposed utility infrastructure
• Recorded easements (including water, PUE, and access easements) • Fire Department operational needs
Updated Fire Marshal Conclusion: The drive-through EVA approach remains acceptable, provided a compliant turning-radius analysis is submitted. All fire apparatus access routes, including the Mason Street emergency connection, shall be protected by recorded emergency vehicle access easements to ensure permanent and enforceable access. Hydrant placement appears flexible under the current utility concept; however, final approval is contingent upon hydrant coverage verification and fire-flow data, and additional hydrants may be required to meet Fire Code standards.

Electric Department

64. The project is going to be in the CHAP underground district. All utilities shall to be fed from underground. The existing power poles along Hudson and Mason will need to be undergrounded.

The power requirements will need a pad-mounted transformer (and possibly a pad-mounted switch).

Easements shall be provided along the frontage for the new electrical equipment and facilities.

65. During our initial review of the requested electrical loads specifically the 1-4000A and the additional services for the two separate buildings. The City of Healdsburg utility policy establishes a hard limit on single-point service sizes: we do not serve any individual service over 2000 Amps. To accommodate the significant power requirements of your development, the project shall modify the current conceptual layouts. Our technical recommendation is to split the total requested load into three separate 2000 Amp services, with each metered independently. Please note that moving to this configuration will introduce a substantial footprint and infrastructure requirement on site:
• Dedicated Transformers: Each of the three 2000A meters will require its own dedicated 750kVA pad-mounted utility transformer.
• Pad-Mounted Switching: Each 750kVA transformer will require a dedicated, pad-mounted switch on-site for isolation and protection.
• Feeder Infrastructure: Your team will need to design and install extensive civil infrastructure (trenches,
conduits, and pull boxes) to route the high-voltage feeders to these switches and link them back Item 7.a
234 of 1062
to our main
distribution system. We will need the required 5’ public utility easements along the south property line and the north line as well. This will require extensive off-site work.

Because this structural change shifts significant spatial and financial requirements onto the site design, we strongly recommend looping in your electrical engineer and civil teams immediately to update the utility easement boundaries and infrastructure paths.

PLANNING COMMISSION

AGENDA STAFF REPORT
MEETING DATE: August 11, 2026
SUBJECT: The Hudson – 359 Hudson Street
PREPARED BY: Ellen McDowell, Senior Planner
STRATEGIC INITIATIVE(S):

Economic Diversity and Sustainable Growth
Affordable Housing
Effective Governance
RECOMMENDED ACTION(S):

Conduct a public hearing on Design Review application DR-0004-2026, Conditional Use Permit application CUP-0001-2026 and Tentative Map SBDV-0001-2026 with State Density Bonus Waiver Requests located at 359 Hudson Street (002-291-033) and associated CEQA exemption and by motion approve a Resolution approving the CEQA exemption and the project based on the suggested findings and subject to the recommended conditions of approval.

BACKGROUND:

On April 2, 2025, the applicant held a community meeting on site, at which members of the public were provided preliminary information about the potential project.

On April 8, 2025, the Planning Commission held a workshop where they reviewed and offered initial feedback on the proposed project.

On October 3, 2025, the City received a Housing Crisis Act (SB 330) application for the property at 359 Hudson Street. The application included the project proposal, site plan, initial elevations, and proposed colors and materials. The Housing Accountability Act (HAA) was enacted in order to provide limits on local government review of housing projects.

SITE AND VICINITY DESCRIPTION:

The project site is located at 359 Hudson Street on the north side of Hudson Street. The site consists of approximately 3.61 acres and is the former Healdsburg Lumber location. The site is relatively flat and is served by existing public streets and municipal water, wastewater, and storm drainage infrastructure.

The project site is a split zoned parcel with zoning designations located in both Mixed Use and R1-6,000 located within the Mixed Use (MU) and Medium Density Residential (MR) General Plan Land Use Designations, respectively.

Item 4.b
14 of 316
Item 7.a
360 of 1062
The surrounding area is characterized by a mix of residential and commercial uses. Single-family residential neighborhoods are located to the north, west, and east. Commercial and mixed-use development is located to the east and south. The project site is within walking distance of the downtown commercial district, public parks, transit services, and other neighborhood-serving amenities and uses.

The site is located within an established neighborhood where a range of housing types and community services already exist. The proposed redevelopment of the underutilized property with senior living, memory care, and affordable units is intended to provide additional housing opportunities within the City.

Figure 1
PROJECT DESCRIPTION:

The applicant, Gallaher Signature Living, LLC, requests approval of a Major Design Review, Major Conditional Use Permit, Tentative Map, State Density Bonus, and associated waivers to construct a Continuing Care Retirement Community (CCRC) and affordable housing development at 359 Hudson Street. The proposed project would redevelop the approximately 3.61-acre site with a four-story senior living building containing 67 independent and assisted living units, a singlestory memory care building with six treatment rooms and one manager's unit, and a separate building containing 10 deed-restricted affordable workforce housing units.

The project includes subdivision of the property into two parcels, one for the senior living community and one for the affordable housing component, together with associated site improvements, landscaping, parking, pedestrian circulation, utilities, and open space.

The senior living community is designed to provide housing and supportive services for older adults, including assisted living and memory care, along with resident amenities such as dining facilities, recreational spaces, wellness areas, landscaped courtyards, and outdoor gathering areas.

The affordable housing component consists of 10 rental units, including eight units affordable to very-low-income households and two units affordable to low-to-moderate income households, supported by on-site parking and residential amenities. As proposed, the project includes a request for a State Density Bonus and multiple waivers of development standards pursuant to State Density Bonus Law.

DISCUSSION/ANALYSIS:

Proposed Affordable Housing and Density Bonus
The City of Healdsburg chose to require certain housing developments to include affordable housing with the adoption of the Healdsburg IHO in 1998. The current IHO requires that 20% of units be rent or sales price restricted to moderate or below moderate-income levels.

In 1979 the State Legislature enacted the Density Bonus Law, Section 65915 to reward developers that choose to construct affordable and senior housing by requiring cities to approve a density bonus which allows the developer to construct more units than would otherwise be permitted.

Through the state density bonus regulations (Government Code § 65915) most developers can request up to a 50% density bonus based upon the number of affordable units proposed, and an 80% increase in densities for projects which are completely affordable. The state regulations are meant to incentivize the production of affordable housing, and any housing developer can elect to take advantage of the allowances created. While the State Density Bonus Law can be complicated, the courts have clarified certain provisions and the relationship between the State Density Bonus Law and a local IHO. The courts have determined affordable units required by an IHO can be used by a developer to request a density bonus. The courts and the Healdsburg Land Use Code have also clarified that the “bonus units” are market-rate units that are added to the project as an incentive to construct affordable housing, and the bonus units are exempt from the IHO.

The applicant is proposing to construct a total of 77 new housing units (51 base units + 26 bonus units). The applicant is proposing to include 67 new senior housing units, ranging in size from 1,075-2,017 square feet and 10 affordable units ranging in size from 372-385 square feet, consistent with Healdsburg IHO and the State Density Bonus Law as discussed below. The City’s IHO requires that units be consistent in square footage, number of bedrooms, finishes, and amenities to the market rate units. Although the City encouraged the applicant to provide larger affordable units and a broader mix of bedroom counts to better comply with the City's Inclusionary Housing Ordinance (IHO), the applicant has requested a concession/incentive under State Density Bonus law to permit smaller affordable units and eliminate the requirement to provide a range of bedroom types among the affordable units.

Item 4.b
16 of 316
Item 7.a
362 of 1062
State Density Bonus Law
The project site is a split zoned parcel with zoning designations located in both Mixed Use and R1-6,000 located within the Mixed Use (MU) and Medium Density Residential (MR) General Plan Land Use Designations, respectively. The Mixed Use portion of the site allows for a maximum of 16 units per acre, while the Medium Density Residential portion of the site allows for a maximum of 6 units per acre. Based upon the project site size of 3.61 acres, the maximum number of allowed units on the site is 51 units as follows:

3.61 Acre Parcel
.67 acres MR @ 6 units/acre = 4.02 units

2.94 acres MU @ 16 units/acre = 47.04 units
Total Units = 51.06 units, which per General Plan rounds down to 51 units.

The applicant is seeking a 50% state density bonus. To be eligible for a 50% density bonus, the applicant must provide at minimum 15% of the base units as Very Low Income (VLI) units (30- 50% AMI). The project proposes eight very low-income units, which is 15.7% of 51, thereby qualifying for the 50% density bonus.

The State Density Bonus calculation is as follows:
51 base units
x 50% State Density Bonus Law = 25.5 units per SDBO rounds to 26 = 77 total units
The project is proposing 77 units (67 senior living + 8 VLI + 2 Low-to-moderate affordable rental units) and as such would conform to State Density Bonus law.

In addition to providing deed-restricted affordable units under State Density Bonus Law the project would need to comply with the City’s Inclusionary Housing Ordinance requirement of 20% affordable housing on site. Inclusionary housing is based on 51 base units and would require 10 affordable units, which the project provides.

State Density Bonus Law Concession/Incentive
In addition to the density bonus, the City is also required to provide “incentives” or “concessions” to each project which qualifies for a density bonus. A concession or incentive is defined as follows:
 A reduction in site development standards or a modification of zoning code or architectural design requirements, such as a reduction in setback or minimum square footage requirements; or
 Approval of mixed-use zone; or
 Other regulatory incentives or concessions which result in identifiable and actual cost reductions.

Based upon the level of affordability provided, the project is entitled to three incentives or concessions. The applicant is requesting the following incentives/concessions:

Item 4.b
17 of 316
Item 7.a
363 of 1062

1. The applicant requests a waiver from Inclusionary Housing Ordinance Section 20.20.030 F(4) which requires affordable units to be consistent in square footage, quality of finishes, and amenities to market rate units. The quality of construction will be similar to the market rate units; however, this requirement would have direct impacts to the project’s construction.

2. The applicant requests a waiver of LUC 20.20.090 F(5) requiring residents of inclusionary units to have access to common open space and recreational amenities. Compliance with this requirement is prohibited by the California Department of Social Services licensing requirements and would physically preclude the project as designed.

3. The applicant requests a waiver of LUC section 20.20.030 F(3) which requires 10% of affordable units to be three-bedroom units.

State Density Bonus Law Waivers
In addition to the Density Bonus, and Concessions/Incentives, the applicant may also request a waiver(s). Waivers or reduction in standards must be granted when the standard would physically preclude the project from being built or designed at the permitted density and with the granted concession/incentive. The City is not required to waive or reduce a standard that would cause a public health or safety problem, cause environmental harm, or harm an historical property, however, the finding must be supported by substantial evidence in the record. The applicant is requesting the following waivers:

Senior Housing

1. The applicant requests a waiver to allow residential use on the ground floor of the proposed development. The waiver is necessary to physically accommodate the density bonus units permitted under SDBL. Limiting ground floor space exclusively to commercial use would significantly constrain residential site layout and reduce the total number of feasible affordable units.

2. The applicant requests a waiver to the Central Healdsburg Avenue Plan’s vision to create a primary new street from Hudson Street to Mason Street. The addition of a new primary street would result in a significant loss of site coverage, directly impacting the density and would preclude the density bonus project as designed.

City staff is in support of this waiver in that the street as proposed does not align with University Street or Mason Street and would prove difficult to align. In lieu of the street the applicant has proposed bicycle and pedestrian access from Mason Street to Hudson Street.

3. The applicant requests a waiver to the maximum FAR from 1.0 to 1.31 to allow for the density bonus project as designed.

4. The applicant requests a waiver for increased building height to accommodate the density bonus and achieve the unit count required to support the inclusion of affordable housing in the project. The height is deviating from the LUC allowable height of 35’ for abutting residential zones to 58’8”.

5. The applicant requests a waiver of LUC section 20.08.030 requiring a 20’ front setback.

The proposed density, minimum street and parking space dimensions would preclude the density bonus project as designed. This is for the memory care facility on Mason Street and will be 10.52’ from Mason Street.

Item 4.b
18 of 316
Item 7.a
364 of 1062
Affordable Housing

1. The applicant requests a waiver to the 10-foot required rear setback for the affordable housing parcel citing LUC section 20.0. Due to the density, street, driveway and parking dimensions it becomes physically impossible to observe the 10-foot rear setback. The rear setback is proposed at 9’.

2. The applicant requests a waiver to the Central Healdsburg Avenue Plan’s vision to create a primary new street from Hudson Street to Mason Street. The addition of a new primary street would result in a significant loss of site coverage, directly impacting the density and would preclude the density bonus project as designed.

3. The applicant requests a waiver to the Central Healdsburg Avenue Plan Urban Frontage Development Standards that require entry spacing, blank wall widths of no more than 8 feet, minimum floor to floor height requirements of 15 feet and requirement that 75% of the first floor facade is to be glazed.

4. The applicant requests a waiver of LUC section 20.08.175 which requires a minimum of 200 square feet of open space per dwelling unit, because this would preclude the project from being constructed at the proposed density, as designed. The project provides a small patio area at the rear of the property for shared use, as well as shared balconies.

When evaluating a waiver, the City is only able to deny if one of the following findings can be made: (1) the project would have a specific, adverse impact upon public health and safety, (2) the project would have an adverse impact on any real property that is listed in the California Register of Historical Resources, or (3) the project would be contrary to state or federal law. Staff has reviewed all requested waivers, and has concluded that all waivers above, and as described in more detail in Attachment 2, can be granted.

Growth Management Ordinance:

The project will not require any Growth Management allocations in that the project consists entirely of senior housing, memory care units and affordable housing units, all of which are exempt from the GMO.

GENERAL PLAN AND LAND USE CODE ANALYSIS:

General Plan
The site has a General Plan land use designation of Mixed Use (MU) and Medium Density Residential (MR). In general, this land use classification provides for commercial and multi-family residential uses. The maximum allowable Floor Area Ratio (FAR) for the designation is 1.0. The proposed FAR is 1.31 and the applicant has requested a waiver under SDBL to meet this requirement. Therefore, the development is consistent with the General Plan’s MU land use designation and the allowable FAR. Development of the site will further the following General Plan policies:

Guiding Principle 2.C: Promote a mix of housing types and affordable housing distributed throughout the community.

Goal LU-A: Orderly development within well-defined urban boundaries maintained by the City’s adopted Urban Service Area/Urban Growth Boundary.

Item 4.b
19 of 316
Item 7.a
365 of 1062
LU-F-2 The City shall encourage mixed use development, including new housing and employment opportunities, as well as reuse of underutilized or vacant industrial land, around the historic railroad depot to support transit use at the depot.

ED-C-1 Promote housing that is affordable to workers who are vital to the community.

Goal H-C Facilitate the provision of affordable housing for those that live and work in Healdsburg.

Goal H-A: Maximize opportunities for the development of a variety of housing types to accommodate anticipated growth, facilitate mobility within both the ownership and rental markets, and encourage a diverse community.

Policy H-A-6:Encourage the retention and development of rental units.

Housing Element Policy 5.7 Encourage senior housing development, rehabilitation, and preservation, particularly in neighborhoods that are accessible to public transit, commercial services, healthcare, and community facilities.

Housing Program 5 Developing Housing Affordable to Very Low-, Low-, Moderate- and middleincome households - Employer-provided housing. Consider options for creating, in partnership with local employers, employer-provided or subsidized housing for local teachers, public safety employees, medical staff etc.

Land Use Code
The project site is a split zoned parcel with zoning designations located in both Mixed Use and R1-6,000 located within the Mixed Use (MU) and Medium Density Residential (MR) General Plan Land Use Designations, respectively. Senior living is a conditionally permitted use within the MU zoning designation, and memory care with 6 or fewer beds is permitted in the R-1-6,000 zoning designation. The proposed project is consistent with the MU and R-1-6,000 designations regarding site coverage, access, and parking except as modified by requested waivers. Discussion of these elements, and applicable requested waivers is provided below.

Parking: The required parking per the Density Bonus Law is calculated and shown in Table 1 below.

The project is consistent with the parking requirements of the Land Use Code for parking for both senior living and affordable housing components of the project.

Lighting: Lights for the proposed building consist of the fixtures identified on sheet L3.1 of Attachment 3. As shown on the elevations for the proposed building, sconce style lights will be affixed to the walls to illuminate the building entryway and parking lot light poles will be provided to provide adequate lighting across the parking area for public safety. All lighting will be downward cast, shielded and protect the night sky.

Access: Vehicle access to the project will be via Hudson Street. Vehicle path of travel has been studied and is detailed in the traffic report included in Attachment 4. Pedestrian access to the project will be provided via sidewalks that will be provided along the project frontage, as well as a public path through the interior of the project connecting Mason Street and Hudson Street.

Trash Disposal/Collection: A trash room is proposed within the buildings, and trash chutes will be located on each floor.

Development Standards: The project complies with all applicable development standards for the Mixed Use and R-1-6,000 zoning designations with respect to lot area, dimensions, building setbacks and heights except as modified by the requested waivers listed above and within Attachment 2.

Height: Pursuant to Section 20.08.170.B.3 of the Land Use Code, the maximum height allowed in the MU Zoning District is 35’ when abutting a site zoned for single family housing as a permitted use. The proposed roof height varies by location, and is 58’8” as measured from the average finished elevation of the natural grade, to the average height between the eaves and the ridge. The applicant is requesting a State Density Bonus Waiver to increase the allowable height in order to accommodate the allowable density bonus.

Maximum Floor Area Ratio/Site Coverage: The site allows for a maximum floor area ratio (FAR) of 100% and a maximum site coverage of 60%. The applicant has requested a State Density Bonus Waiver to allow increased FAR for parcel 1 to allow a 131% FAR. The project proposes a maximum of 37.7%site coverage for parcel 1 and 19.6% site coverage for parcel 2 and is within the allowable 60% site coverage.

Open Space: Pursuant to Section 20.08.175(B) of the Land Use Code the project requires a minimum of 200 square feet of usable open space per dwelling. The senior housing component exceeds this requirement by use of outdoor areas including recreational areas, and private balconies. The affordable component of the project is requesting a waiver as allowed by State Density Bonus Law.

CENTRAL HEALDSBURG AVENUE PLAN (CHAP) ANALYSIS:

The project site is located within the Central Healdsburg Avenue Plan (CHAP), which provides planning and design guidance for redevelopment within the corridor. The proposed project Item 4.b

incorporates several CHAP principles by redeveloping an underutilized infill site with a mix of senior living and affordable housing, providing pedestrian connections, landscaping, and streetscape improvements, and locating housing within close proximity to the future SMART station, downtown Healdsburg, employment opportunities, and community services. The project also includes architectural and site design elements intended to complement the surrounding neighborhood and create an active, pedestrian-oriented streetscape along Hudson Street.

The project is generally consistent with several CHAP goals and principles, including fostering a diversity of housing options, supporting infill redevelopment, improving pedestrian and bicycle connectivity, and encouraging sustainable neighborhood development. The project also includes requests for waivers from certain CHAP development standards and design provisions pursuant to State Density Bonus Law, including standards related to urban frontage requirements and the planned north-south street connection identified in the CHAP. Regarding the planned street connection, staff is supportive of this waiver in that the proposed street does not align with University Street and would prove to be infeasible to construct on the current site. In lieu of the street, the applicant has proposed public bicycle and pedestrian access from Mason Street to Hudson Street. These waiver requests are discussed in greater detail above, and within Attachment

2. FINDINGS:

Major Design Review Findings (DR-0004-2026):

Pursuant to Land Use Code section 20.28.125, the Planning Commission is required to make the following findings in order to approve a Major Design Review Permit; staff has provided suggested findings below.

A. The proposed development or use is consistent with all applicable policies and requirements of the General Plan and Land Use Code.

The proposed use is within the range of uses contemplated in the Mixed-Use (majority of the site) and Medium Density Residential General Plan land use designation. For the Mixed Use designation, where a mix of uses is proposed on the same site, residential development up to 16 units per acre may be combined with nonresidential uses when compatible with allowable nonresidential uses on the same and adjoining sites and designed to minimize impacts on residents from noise and other elements typically associated with a thriving commercial area.

The proposed multi-family senior living facility use is consistent with the anticipated uses identified in the General Plan, as well as all applicable General Plan policies including:
 Housing Element Policy 5.7 Encourage senior housing development, rehabilitation, and preservation, particularly in neighborhoods that are accessible to public transit, commercial services, healthcare, and community facilities (the Project will provide 57 senior housing units within walking distance to several commercial uses, the Foss Creek walking trail, and the First & Mason St bus stop.
 General Plan Policy ED-C-1 Promote housing that is affordable to workers who are vital to the community (the Project provides much-needed affordable workforce housing within walking distance for employees of the senior housing facility)  Housing Program 5 – Developing Housing Affordable to Very Low, Low, Moderate, and Middle-Income Households. Employer-Provided Housing. Consider options for creating, in partnership with local employers, employer-provided or subsidized housing for local Item 4.b

workers, including teachers, public safety employees, medical staff, etc. (the Project provides much-needed affordable workforce housing within walking distance for employees of the senior housing facility)
The project meets or exceeds all development requirements in the Land Use Code including building height, lot coverage, setbacks, landscaping, and on-site parking and loading except with concessions and waivers permitted by the State Density Bonus Law.

B. The proposed design of the development or use, and all appurtenant structures, is consistent with the policies set forth in the Citywide Design Guidelines, as may be amended from time to time.

The project is outside the purview of the Citywide Design Guidelines and is subject to finding E below.

C. The proposed development or use is consistent with the purposes of the zoning district in which it is located.

The MU and R-1-6,000 zoning designations implement the Mixed Use and Medium Density Residential land use designations of the Healdsburg General Plan. The special purposes of the districts provide well-planned multi-family housing The multi-family project is a conditionally permitted use in the MU zoning district.

D. The proposed development or use is consistent with all other conditions imposed by the Planning Commission or City Council with respect to any matter related to the purpose of design review.

The property does not have any conditions that were previously placed on the site. As part of the subject project, conditions of approval have been included in the resolution that will be required to be complied with throughout the life of the project. The proposed project is subject to the Land Use Code, including allowed uses and development standards, and the Central Healdsburg Avenue Plan. As noted above, the proposed project has been found to be consistent with the Land Use Code, State Density Bonus Law and Central Healdsburg Avenue Plan and as such the proposed project is consistent with any conditions imposed by the Planning Commission or City Council.

E. For proposed developments or uses in the Central Healdsburg Avenue Plan area, the design of the development or use, and all appurtenant structures, is consistent with the policies set forth in Chapter IV, "Building Design Framework," of the Central Healdsburg Avenue Plan dated November 2013 and adopted by the Healdsburg City Council on January 21, 2014, as may be amended from time to time.

The proposed project is consistent with the scale and character of residential commercial and industrial uses found within the Central Healdsburg Avenue Plan except as modified by requested waivers permitted through State Density Bonus Law. The proposed colors and materials are compatible with the surrounding area and respect the character of the City. The front setback and the building’s mass, articulation, and scale are consistent, anticipated and compatible with development in the area. Therefore, the design of the proposed project is consistent with the Central Healdsburg Avenue Plan policies included in Chapter IV, “Building Design Framework”.

Conditional Use Permit Findings (CUP-0001-2026):

Item 4.b
23 of 316
Item 7.a
369 of 1062
Pursuant to Land Use Code section 20.28.165, the Planning Commission is required to make the following findings in order to approve a Conditional Use Permit. Staff has provided suggested findings below.

1. The proposed location and operation of the conditional use is in accord with the Healdsburg general plan and any applicable planned development, specific or area plan.

The Conditional Use Permit pertains to the use as General Residential Care, defined as “a State-licensed facility, place or structure that is maintained and operated to provide nonmedical residential care, day treatment or foster agency services for seven or more adults and/or children as defined in the California health and Safety Code. This use includes the administration of limited medical assistance (e.g., dispensing of prescribed medications).” General Residential Care is a conditionally permitted use within the Mixed-Use zoning designation. As such, the use is consistent with the Healdsburg General Plan and Central Healdsburg Avenue Plan.

2. The proposed location and operation of the conditional use is consistent with the applicable development standards of this Land Use Code.

The use is a conditionally permitted use within the Mixed-Use zoning designation as described in the finding above. In addition, the project is consistent with the development standards of the Land Use Code except as modified by the waivers as permitted by State Density Bonus Law.

3. The proposed location of the conditional use and the conditions under which it would be operated and maintained will not be detrimental to public health and safety or materially injurious to uses, properties or improvements in the vicinity.

The Conditional Use Permit pertains to the conditionally permitted use as Residential Care within the Mixed-Use designation. The use is anticipated and conditionally permitted and therefore it can be seen with certainty that the use will not have a detrimental effect on the public health and safety or materially injurious to uses, properties or improvements in the vicinity.

Tentative Parcel Map Findings (SBDV-0001-2026):

Pursuant to Land Use Code Section 17.04.100, the Planning Commission is required to make the following findings in order to approve a Tentative Parcel Map; staff has provided suggested findings below.

The planning commission shall base its recommendation on a tentative subdivision map of four or fewer lots on the findings below:

1. The proposed map and its design and improvements are consistent with the general plan and any applicable specific plan.

The Healdsburg 2030 General Plan designations of the property is Mixed-Use (MU), and Medium Density Residential (MR). In general, these land use classifications provide for commercial and residential uses. The proposed project will construct a new Residential Care facility and multi-family for-rent affordable housing units and is therefore consistent with the permitted and conditionally permitted uses of the MU and MR designations. The project’s existing access is consistent with the Transportation Element. The project site is located within the boundaries of the Central Healdsburg Avenue Plan Area. It should be noted that the CHAP Item 4.b
24 of 316
Item 7.a
370 of 1062
include a proposed extension of University Street through the project site. However, it has been determined that this proposed extension is infeasible and the applicant has requested a waiver for this requirement. The applicant will be providing public pedestrian and bicycle access through the site to assist in the connection from Mason to Hudson Street.

2. The site is physically suitable for the type and proposed density of development.

The site is physically suitable for the proposed type and density of the proposed development as provided for in the General Plan, Land Use Code and State Density Bonus Law. There are no physical constraints on the property which would prohibit the development of the site.

3. The design of the subdivision and the proposed improvements are not likely to cause substantial environmental damage or substantially and avoidably injure fish or wildlife or their habitat.

The Project site is developed and does not contain suitable habitat for fish or wildlife. Further, the Project is categorically exempt from the California Environmental Quality Act (“CEQA”) pursuant to CEQA Guidelines Section 15331 Class 32 Infill Exemption, as provided above.

Further, the project is categorically exempt from CEQA pursuant CEQA Guidelines Section 15315 Class 15 Minor Land Divisions, in that the project does not exceed 4 parcels; is in conformance with the General Plan; no variances or exceptions are required; access and services to the site are available; the parcel was not involved in a division of a larger parcel within the last 2 years; and the parcel does not have an average slope greater than 20%.

4. The design of the subdivision and the type of improvements are not likely to cause serious public health problems.

All project improvements will be designed and constructed in accordance with City standards to ensure protection of the public health. A construction Health Risk Assessment also determined that diesel particulate matter (DPM) cancer risk, chronic non-cancer hazard, and PM2.5 concentrations at nearby sensitive receptors, including adjacent residences and a nearby preschool, would remain below Bay Area Air District significance thresholds.

Operational impacts would likewise be less than significant because the residential project would not include substantial sources of toxic air contaminants or diesel truck traffic.

5. The design of the subdivision and the type of improvements will not conflict with easements, acquired by the public at large, for access through or use of property within the proposed subdivision.

There are no public access easements located on the property except as to be conditioned by the project.

6. Unless otherwise provided by the Subdivision Map Act, the design of the subdivision provides, to the extent feasible, for future passive or natural heating or cooling opportunities in the subdivision.

The resultant lots are situated where the development of the property will provide passive heating due to a southwestern exposure. The new structures on the property will be required to be constructed in accordance with the energy conservation standards of the California Building Code.

After public comment and deliberation, the Planning Commission may consider alternatives to address concerns provided from the public. This may include approving the project as conditioned or as modified by the Planning Commission, continuing the project to a later date to address design-related concerns, or denying the project as proposed.

ENVIRONMENTAL REVIEW:

The project qualifies for a Class 32 categorical exemption under the California Environmental Quality Act Guidelines Section 15332, In-Fill Development Projects, in that the proposed buildings and associated site improvements meet the following conditions contained in the Class 32 In-Fill Exemption:
(a) The project is consistent with the applicable general plan designation and all applicable general plan policies as well as the applicable zoning designation and regulations.

The proposed project is located on a split-zoned site within the Mixed Use (MU) and Medium Density Residential General Plan Land Use designation and the Mixed Use (MU) and R-1-6,000 Zoning Districts. The proposed project is a conditionally permitted use within the MU zone and a permitted use within the R-1-6,000 zoning district, and the proposed buildings and site improvements are consistent with the development standards of the zoning district and are consistent with the development standards of the zoning district and general development standards set forth in the Land Use Code except as modified by Density Bonus incentives and waivers. The courts have determined modifications required by the Density Bonus Law do not disqualify the project from claiming the exemption.
(b) The proposed development occurs within the city limits on a project site of no more than five acres substantially surrounded by urban uses.

The subject site is 3.17 acres, located within the city limits of the City of Healdsburg, and is adjacent to urban uses on three sides.
(c) The project site has no value as habitat for endangered, rare or threatened species.

The project site is a currently developed, paved site with existing commercial buildings and provides no value as habitat for endangered, rare, or threatened species. (d) Approval of the project would not result any significant effects relating to traffic, noise, air quality, or water quality.
 Traffic: Small infill projects located in the downtown area have been prescreened and determined to result in less than 15% or below the countywide average for Vehicle Miles Travelled (VMT) per capita if the project is consistent with the General Plan Land Use designation. The project is located within the pre-screened area and is exempt from any further traffic analysis.  Noise: The Project-specific Noise Impact Analysis concluded that the proposed Continuing Care Retirement Community would result in less-than-significant noise and vibration impacts. Construction noise would comply with the City of Healdsburg Municipal Code by occurring only during permitted hours and incorporating project design features such as temporary 7-foot-high sound barriers, properly maintained equipment, and a designated disturbance Item 4.b

coordinator. Construction noise at the nearest residence is projected to meet the Federal Transit Administration (FTA) criterion of 80 dBA Leq (8-hour).

Operational noise from mechanical equipment, pool equipment, and projectgenerated traffic would remain below the City's noise standards, and construction and operational vibration levels would also remain below applicable FTA thresholds. The project is not located within an airport noise compatibility area and would not expose residents or workers to excessive aircraft noise. Accordingly, no significant noise impacts are anticipated.  Air Quality: The Project-specific Air Quality Analysis concluded that the proposed Project would result in less-than-significant air quality impacts.

Construction-related fugitive dust would be minimized through implementation of required Best Management Practices (BMPs) pursuant to General Plan Policy NR-28, and construction exhaust emissions would remain below Bay Area Air District significance thresholds for reactive organic gases (ROG), nitrogen oxides (NOx), particulate matter (PM10), and fine particulate matter (PM2.5). A construction Health Risk Assessment also determined that diesel particulate matter (DPM) cancer risk, chronic non-cancer hazard, and PM2.5 concentrations at nearby sensitive receptors, including adjacent residences and a nearby preschool, would remain below Bay Area Air District significance thresholds. Operational impacts would likewise be less than significant because the residential project would not include substantial sources of toxic air contaminants or diesel truck traffic. Accordingly, the Project would not result in significant construction or operational air quality impacts.  Water Quality: The project will be required to install post construction stormwater treatment best management practices (BMP) in accordance with the current version of the Low Impact Development (LID) Technical Design Manual. A Final Stormwater Management Plan will be required to be submitted with the building permit plans for the site.
(e) The site can be adequately served by all required utilities and public services.

The site is located within the City of Healdsburg urban service area and can be adequately served by the City’s water and sewer systems. Electric is provided by the City of Healdsburg Utilities. Natural gas is provided to the site by Pacific Gas and Electric. The City of Healdsburg provides Fire and Police services for the site.

In addition, the project is categorically exempt pursuant to California Environmental Quality Act Guidelines Section 15315 Class 15 Minor Land Divisions, and 15061(b), in that the project does not exceed 4 parcels; is in conformance with the General Plan; no variances or exceptions are required; access and services to the site are available; the parcel was not involved in a division of a larger parcel within the last 2 years; and the parcel does not have an average slope greater than 20%.

3. Major Design Review Findings (DR-0004-2026):

Pursuant to Land Use Code section 20.28.125, the Planning Commission finds:

A. The proposed development or use is consistent with all applicable policies and requirements of the General Plan and Land Use Code.

The proposed use is within the range of uses contemplated in the Mixed-Use (majority of the site) and Medium Density Residential General Plan land use designation. For the Mixed Use designation, where a mix of uses is proposed on the same site, residential development up to 16 units per acre may be combined with nonresidential uses when compatible with allowable nonresidential uses on the same and adjoining sites and designed to minimize impacts on residents from noise and other elements typically associated with a thriving commercial area. The proposed multi-family senior living facility use is consistent with the anticipated uses identified in the General Plan, as well as all applicable General Plan policies including:
• Housing Element Policy 5.7 Encourage senior housing development, rehabilitation, and preservation, particularly in neighborhoods that are accessible to public transit, commercial services, healthcare, and community facilities (the Project will provide 57 Item 4.b

senior housing units within walking distance to several commercial uses, the Foss Creek walking trail, and the First & Mason St bus stop.
• General Plan Policy ED-C-1 Promote housing that is affordable to workers who are vital to the community (the Project provides much-needed affordable workforce housing within walking distance for employees of the senior housing facility) • Housing Program 5 – Developing Housing Affordable to Very Low, Low, Moderate, and Middle-Income Households. Employer-Provided Housing. Consider options for creating, in partnership with local employers, employer-provided or subsidized housing for local workers, including teachers, public safety employees, medical staff, etc. (the Project provides much-needed affordable workforce housing within walking distance for employees of the senior housing facility)
The project meets or exceeds all development requirements in the Land Use Code including building height, lot coverage, setbacks, landscaping, and on-site parking and loading except with concessions and waivers permitted by the State Density Bonus Law.

B. The proposed design of the development or use, and all appurtenant structures, is consistent with the policies set forth in the Citywide Design Guidelines, as may be amended from time to time.

The project is outside the purview of the Citywide Design Guidelines and is subject to finding E below.

C. The proposed development or use is consistent with the purposes of the zoning district in which it is located.

The MU and R-1-6,000 zoning designations implement the Mixed Use and Medium Density Residential land use designations of the Healdsburg General Plan. The special purposes of the districts provide well-planned multi-family housing The multi-family project is a conditionally permitted use in the MU zoning district.

D. The proposed development or use is consistent with all other conditions imposed by the Planning Commission or City Council with respect to any matter related to the purpose of design review.

The property does not have any conditions that were previously placed on the site. As part of the subject project, conditions of approval have been included in the resolution that will be required to be complied with throughout the life of the project. The proposed project is subject to the Land Use Code, including allowed uses and development standards, and the Central Healdsburg Avenue Plan. As noted above, the proposed project has been found to be consistent with the Land Use Code, State Density Bonus Law and Central Healdsburg Avenue Plan and as such the proposed project is consistent with any conditions imposed by the Planning Commission or City Council.

E. For proposed developments or uses in the Central Healdsburg Avenue Plan area, the design of the development or use, and all appurtenant structures, is consistent with the policies set forth in Chapter IV, "Building Design Framework," of the Central Healdsburg Avenue Plan dated November 2013 and adopted by the Healdsburg City Council on January 21, 2014, as may be amended from time to time.

The proposed project is consistent with the scale and character of residential commercial and industrial uses found within the Central Healdsburg Avenue Plan except as modified by requested waivers permitted through State Density Bonus Law. The proposed colors and Item 4.b

materials are compatible with the surrounding area and respect the character of the City.

The front setback and the building’s mass, articulation, and scale are consistent, anticipated and compatible with development in the area. Therefore, the design of the proposed project is consistent with the Central Healdsburg Avenue Plan policies included in Chapter IV, “Building Design Framework”.

4. Conditional Use Permit Findings (CUP-0001-2026):

Pursuant to Land Use Code section 20.28.165, the Planning Commission finds:

1. The proposed location and operation of the conditional use is in accord with the Healdsburg general plan and any applicable planned development, specific or area plan.

The Conditional Use Permit pertains to the use as General Residential Care, defined as “a State-licensed facility, place or structure that is maintained and operated to provide nonmedical residential care, day treatment or foster agency services for seven or more adults and/or children as defined in the California health and Safety Code. This use includes the administration of limited medical assistance (e.g., dispensing of prescribed medications).” General Residential Care is a conditionally permitted use within the Mixed-Use zoning designation. As such, the use is consistent with the Healdsburg General Plan and Central Healdsburg Avenue Plan.

2. The proposed location and operation of the conditional use is consistent with the applicable development standards of this Land Use Code.

The use is a conditionally permitted use within the Mixed-Use zoning designation as described in the finding above. In addition, the project is consistent with the development standards of the Land Use Code except as modified by the waivers as permitted by State Density Bonus Law.

3. The proposed location of the conditional use and the conditions under which it would be operated and maintained will not be detrimental to public health and safety or materially injurious to uses, properties or improvements in the vicinity.

The Conditional Use Permit pertains to the conditionally permitted use as Residential Care within the Mixed-Use designation. The use is anticipated and conditionally permitted and therefore it can be seen with certainty that the use will not have a detrimental effect on the public health and safety or materially injurious to uses, properties or improvements in the vicinity.

5. Tentative Parcel Map Findings (SBDV-0001-2026):

Pursuant to Land Use Code Section 17.04.100, the Planning Commission finds:

The planning commission shall base its recommendation on a tentative subdivision map of four or fewer lots on the findings below:

1. The proposed map and its design and improvements are consistent with the general plan and any applicable specific plan.

The Healdsburg 2030 General Plan designations of the property are Mixed-Use (MU), and Medium Density Residential (MR). In general, these land use classifications provide for commercial and residential uses. The proposed project will construct a new Residential Item 4.b
36 of 316
Item 7.a
382 of 1062

Page 9 of 19 ends

Care facility and multi-family for-rent affordable housing units and is therefore consistent with the permitted and conditionally permitted uses of the MU and MR designations. The project’s existing access is consistent with the Transportation Element. The project site is located within the boundaries of the Central Healdsburg Avenue Plan Area. It should be noted that the CHAP includes a proposed extension of University Street through the project site. However, it has been determined that this proposed extension is infeasible and the applicant has requested a waiver of this requirement. The applicant will be providing public pedestrian and bicycle access through the site to assist in the connection from Mason to Hudson Street and the planned SMART station.

2. The site is physically suitable for the type and proposed density of development.

The site is physically suitable for the proposed type and density of the proposed development as provided for in the General Plan, Land Use Code, and State Density Bonus Law. There are no physical constraints on the property which would prohibit the development of the site.

3. The design of the subdivision and the proposed improvements are not likely to cause substantial environmental damage or substantially and avoidably injure fish or wildlife or their habitat.

The Project site is developed and does not contain suitable habitat for fish or wildlife.

Further, the Project is categorically exempt from the California Environmental Quality Act (“CEQA”) pursuant to CEQA Guidelines Section 15331 Class 32 Infill Exemption, as provided above. Further, the project is categorically exempt from CEQA pursuant CEQA Guidelines Section 15315 Class 15 Minor Land Divisions, in that the project does not exceed 4 parcels; is in conformance with the General Plan; no variances or exceptions are required; access and services to the site are available; the parcel was not involved in a division of a larger parcel within the last 2 years; and the parcel does not have an average slope greater than 20%.

4. The design of the subdivision and the type of improvements are not likely to cause serious public health problems.

All project improvements will be designed and constructed in accordance with City standards to ensure protection of the public health. A construction Health Risk Assessment also determined that diesel particulate matter (DPM) cancer risk, chronic non-cancer hazard, and PM2.5 concentrations at nearby sensitive receptors, including adjacent residences and a nearby preschool, would remain below Bay Area Air District significance thresholds. Operational impacts would likewise be less than significant because the residential project would not include substantial sources of toxic air contaminants or diesel truck traffic.

5. The design of the subdivision and the type of improvements will not conflict with easements, acquired by the public at large, for access through or use of property within the proposed subdivision.

Item 4.b
37 of 316
Item 7.a
383 of 1062

Page 10 of 19 ends

There are no public access easements located on the property except as to be conditioned by the project.

6. Unless otherwise provided by the Subdivision Map Act, the design of the subdivision provides, to the extent feasible, for future passive or natural heating or cooling opportunities in the subdivision.

The resultant lots are situated where the development of the property will provide passive heating due to a southwestern exposure. The new structures on the property will be required to be constructed in accordance with the energy conservation standards of the California Building Code.

BE IT FURTHER RESOLVED that the Healdsburg Planning Commission does hereby approve DR-0004-2026, CUP-0001-2026 AND SBDV-0001-2026 subject to the conditions attached hereto as Exhibit A, which is incorporated herein by reference.

Fire Department

54. Drive-through EVA concept acceptable; no hammerhead required. The Fire Department acknowledges the proposed drive-through emergency vehicle access (EVA) configuration in lieu of a hammerhead, subject to final apparatus maneuvering verification.

55. Fire apparatus turning-radius / Auto TURN exhibit required. Submit a turning-radius analysis demonstrating compliant ingress, on-site circulation, and egress for Healdsburg Fire apparatus. The exhibit shall verify:
• Entry from Hudson Street
• Internal circulation through fire lanes
• Maneuvering adjacent to parking lot access points and porte cochere • Use of the Mason Street emergency access (if intended for operational use) This is required to confirm that the drive-through EVA performs as intended under real operating conditions.

56. Emergency Vehicle Access (EVA) easement required. All portions of the fire apparatus access route that are not located within the public right-of-way shall be provided with a recorded emergency vehicle access easement.
• Easement shall be reviewed and approved by the Fire Department prior to recordation • Easement shall ensure permanent, unobstructed access for fire apparatus • Easement language shall prohibit obstructions, parking, or modifications that reduce required clearances

57. Mason Street emergency access – easement and gate requirements. The secondary access connection to Mason Street, identified as a gated emergency-access-only driveway, shall:
• Be located within a recorded EVA easement
• Include Fire Department–approved gate design (Knox access, emergency override, failsafe operation) • Maintain full required fire access width and vertical clearance at all times

58. Maintain required fire access widths. Plans indicate 20-foot fire lanes and 26-foot aerial access zones. Final plans shall dimension and maintain these widths continuously, free of encroachments from parking, landscaping, structures, or site features.

59. Parking-lot interface and circulation conflicts. The turning-radius exhibit shall account for real-world conditions at parking lot entrances, including vehicle stacking, stall overhang, and curb geometry. Fire lanes shall remain clear and functional during peak site use.

60. Hydrant layout – additional opportunities to be evaluated. The utility plan identifies an existing hydrant and indicates new hydrant placement to be determined by the Fire Marshal.

Based on the site layout, additional hydrant placement—particularly toward the northeast/Mason Street side—should be evaluated to improve coverage.

Item 4.b
45 of 316
Item 7.a
391 of 1062

Page 18 of 19 ends

61. Hydrant coverage exhibit required. Provide a plan demonstrating that all portions of the buildings are within required fire department hose reach (typically 250 feet) from an approved hydrant, measured along approved access routes.

62. Fire flow and flow-test data required. Submit current hydrant flow test data and required fireflow calculations for all structures. Water supply adequacy must be confirmed prior to approval of site design.

63. Coordinate hydrants and fire service with utility plan and easements. Final hydrant locations, underground fire service routing, and associated appurtenances shall be coordinated with:
• Existing and proposed utility infrastructure
• Recorded easements (including water, PUE, and access easements) • Fire Department operational needs
Updated Fire Marshal Conclusion: The drive-through EVA approach remains acceptable, provided a compliant turning-radius analysis is submitted. All fire apparatus access routes, including the Mason Street emergency connection, shall be protected by recorded emergency vehicle access easements to ensure permanent and enforceable access. Hydrant placement appears flexible under the current utility concept; however, final approval is contingent upon hydrant coverage verification and fire-flow data, and additional hydrants may be required to meet Fire Code standards.

Electric Department

64. The project is going to be in the CHAP underground district. All utilities shall to be fed from underground. The existing power poles along Hudson and Mason will need to be undergrounded. The power requirements will need a pad-mounted transformer (and possibly a pad-mounted switch). Easements shall be provided along the frontage for the new electrical equipment and facilities.

65. During our initial review of the requested electrical loads specifically the 1-4000A and the additional services for the two separate buildings. The City of Healdsburg utility policy establishes a hard limit on single-point service sizes: we do not serve any individual service over 2000 Amps. To accommodate the significant power requirements of your development, the project shall modify the current conceptual layouts. Our technical recommendation is to split the total requested load into three separate 2000 Amp services, with each metered independently. Please note that moving to this configuration will introduce a substantial footprint and infrastructure requirement on site:
• Dedicated Transformers: Each of the three 2000A meters will require its own dedicated 750kVA pad-mounted utility transformer.
• Pad-Mounted Switching: Each 750kVA transformer will require a dedicated, padmounted switch on-site for isolation and protection. • Feeder Infrastructure: Your team will need to design and install extensive civil infrastructure (trenches,
conduits, and pull boxes) to route the high-voltage feeders to these switches and link them back to our main
distribution system. We will need the required 5’ public utility easements along the south property line and the north line as well. This will require extensive off-site work.

Project Narrative
Gallaher Signature Living – Healdsburg
359 Hudson Street
Healdsburg, CA 95448
Proposed Project
Gallaher Signature Living, LLC (“Applicant”) proposes the Healdsburg Continuing Care Retirement Community (CCRC) Project at 359 Hudson Street, Healdsburg, California in Sonoma County as new residential construction consisting of 67 luxury senior living units, memory care, marketing and recreation space, indoor and outdoor amenities, 10 for-rent 100% affordable housing units, landscaped recreational and leisure areas, and related improvements. The Project is a “housing development project” subject to the Housing Crisis Act and protected by the Housing Accountability Act (“HAA”), Gov. Code § 65589.5.

The Project site (“Site” or “Property”) consists of a single legal parcel of approximately 3.61 acres, Assessor’s Parcel Number (APN) 002-291-033, located largely on a flat, developed area within the Central Healdsburg Avenue Plan (CHAP). The General Plan land use designation for the Site is Medium Density Residential and Mixed Use, with zoning classifications of R-1-6,000 and Mixed Use. General Residential Care Facilities for the Elderly are conditionally permitted within the Site’s zoning. The legal description for APN 002-291-033 is included with this application submittal.

The Project proposes to subdivide the Site into two parcels: a 0.44-acre parcel designated for affordable workforce housing, and a 3.17-acre parcel designated for the senior living community. Of the 3.17-acre senior parcel, approximately 0.67 acres located on the northernmost portion of the Site is zoned R-1-6,000, while the remaining 2.5 acres located on the southwestern portion of the Site is zoned Mixed Use.

Continuing Care Retirement Communities (CCRC), a subset of Residential Care Facilities for the Elderly (RCFE) are regulated by the Continuing Care Contracts Branch of the California Department of Social Services and offer longterm contracts, typically for the resident’s lifetime, to provide housing and residential services, and subject to a Skilled Nursing Facility (SNF) License, may also provide skilled nursing care. The proposal for 359 Hudson Street includes assisted living services but does not include Skilled Nursing Facility (SNF) services. CCRC’s are required to obtain a Residential Care Facility for the Elderly (RCFE) license through the California Department of Social Services.

In addition to a Continuing Care Retirement Community and corresponding amenities, the Project site would include the development of affordable workforce housing units serving varying levels of affordability, including 8 very-low income unis at 50% AMi. The proposed Project, consistent with Healdsburg’s Strategic Plan, aims to promote cityItem 4.b 48 of 316

GALLAHER SIGNATURE LIVING • GALLAHERSL.COM
centered growth and infill development and redevelopment of underutilized sites. Proposing the highest and best use for the site, the proposed Project intends to respect existing neighborhood character, patterns, and forms.

The Applicant is seeking entitlements under SB 330, the State Density Bonus Law (SDBL), Major Conditional Use Permit (MCUP), and Major Design Review. The Applicant is also pursuing CEQA compliance under AB130.

SB330 Housing Crisis Act of 2019
The proposed Project is protected by the Housing Crisis Act of 2019. The Housing Accountability Act, which is part of the Planning and Zoning Law, prohibits a local agency from disapproving, or conditioning approval in a manner that renders infeasible, a housing development project for very low, low-, or moderate-income households or an emergency shelter unless the local agency makes specified written findings based on a preponderance of the evidence in the record. The act specifies that one way to satisfy that requirement is to make findings that the housing development project or emergency shelter is inconsistent with both the jurisdiction’s zoning ordinance and general plan land use designation as specified in any element of the general plan as it existed on the date the application was deemed complete. The act requires a local agency that proposes to disapprove a housing development project that complies with applicable, objective general plan and zoning standards and criteria that were in effect at the time the application was deemed to be complete, or to approve it on the condition that it be developed at a lower density, to base its decision upon written findings supported by substantial evidence on the record that specified conditions exist, and places the burden of proof on the local agency to that effect. The act requires a court to impose a fine on a local agency under certain circumstances and requires that the fine be at least $10,000 per housing unit in the housing development project on the date the application was deemed complete.

State Density Bonus Law
As a senior and affordable housing development serving very low-income households, the proposed Project qualifies under the State Density Bonus Law (Gov. Code § 65915) for a 50% density bonus, unlimited waivers of development standards, and reduced parking requirements. Based on the levels of affordability provided, the Project is also entitled to three (3) concessions or incentives under the State Density Bonus Law. The Project proposes utilizing State Density Bonus Law to maximize the number of allowable units on the site and align with the City of Healdsburg’s General Plan and Housing Element goals. (C) Three incentives or concessions for projects that include at least 24 percent of the total units for lower income households, at least 15 percent for very low-income households, or at least 30 percent for persons and families of moderate income in a development in which the units are for sale.

Concessions/Incentives:

The proposed Project, entitled to three (3) State Density Bonus Law concessions/incentives by way of achievable affordability levels. The Applicant has identified the following three concessions/incentives:

Item 4.b
49 of 316
Item 7.a
395 of 1062
GALLAHER SIGNATURE LIVING • GALLAHERSL.COM
Parcel 2 – Affordable Housing:

Concession/Incentive 1: Healdsburg Municipal Code 20.20.030 - Inclusionary Housing F4 The Applicant requests a concession/incentive of Healdsburg Municipal Code 20.20.030 - Inclusionary Housing F4, which states that affordable units should be consistent in square footage, quality of finishes, and amenities to market rate units. While the quality of construction for the affordable units will be similar to the market rate units, some portions of this requirement would have direct impacts to the project’s construction and operational costs by adding buildable area, thus increasing construction costs, management costs, and landlord supported utility costs. The Applicant requests a concession/incentive.

Concession/Incentive 2: Healdsburg Municipal Code 20.20.030 - Inclusionary Housing F5 The Applicant requests a concession/incentive of Healdsburg Municipal Code 20.20.030 - Inclusionary Housing F5, which requires that residents of inclusionary units have access to the project’s common open spaces or recreational amenities. Compliance with this requirement is prohibited by law under the California Department of Social Services licensing requirements and physically precluding the density bonus Project as designed.

Concession/Incentive 3: Inclusionary Housing - Three-Bedroom Requirement F3 The Applicant requests a waiver of Healdsburg Municipal Code 20.20.030 - Inclusionary Housing F3, which requires that 10% of the affordable units be three-bedroom units. Compliance with this requirement would have direct impacts to the project’s construction and operational costs by adding buildable area, thus increasing construction costs, management costs, and landlord supported utility costs.

Waivers:

The proposed Project, entitled to unlimited waivers by way of the achievable affordability levels, has identified the following ten (13) State Density Bonus Law waivers of development standards (between the two parcels) and reserves the right to request additional State Density Bonus Law waivers during the Design Review process.

Parcel 1 – Senior Living:

Waiver 1: Waiver of Central Healdsburg Avenue Plan Urban Frontage Type (Ground Floor Residential Use) The Applicant requests the use of a waiver to allow residential use on the ground floor of the proposed development.

This waiver is necessary to physically accommodate the density bonus units permitted under State Density Bonus Law. Limiting ground floor space exclusively to commercial use would significantly constrain residential site layout and reduce the total number of feasible affordable units.

Waiver 2: The Applicant is requesting a waiver to the Central Healdsburg Avenue Plan’s vision to create a primary new street running north to south on the eastern portion of the proposed Project site. The addition of a primary new street across the proposed Project site would result in a significant loss of site coverage, directly impacting density by reducing the number of proposed units and would physically preclude the density bonus Project as designed.

Item 4.b

Item 7.a
396 of 1062
GALLAHER SIGNATURE LIVING • GALLAHERSL.COM
Additionally, based on conversations with the City of Healdsburg during the One Stop Shop on January 30th, 2025, the City supported the idea of a path in lieu of a primary street as described in the Central Healdsburg Avenue Plan citing infrastructure challenges and the need for property acquisition. A Traffic Impact Study performed by W Trans on November 17, 2025, determined there is no operational benefit to extending University Street to Hudson Street, as envisioned in the CHAP, but there are several negative aspects to the proposal, including increased driving times and placing traffic near sensitive housing facilities.

Discussions with Public Works revealed that the proposed new street connection would require substantial reengineering at Mason Street, including modifications to existing infrastructure. Additionally, implementation of the proposed street would necessitate the City of Healdsburg acquiring property interests from two separate landowners in order to accommodate the alignment as currently envisioned.

Waiver 3: Maximum Floor Area Ratio.

Pursuant to California Government Code § 65915(d), the Applicant requests a waiver of Land Use Code 20.08.165 to allow an increase in Floor Area Ratio from 1.0 to 1.31 as not doing so would preclude the density bonus Project as designed.

Waiver 4: Increased Building Height
Pursuant to California Government Code § 65915(d), the Applicant requests a waiver to allow an increase in maximum building height to approximately XX feet, exceeding the height limit otherwise permitted by the Healdsburg applicable zoning regulations as defined. This waiver is necessary to accommodate the density bonus units and to achieve the unit count required to support the inclusion of affordable housing in the project. Strict compliance with the existing height limitation would physically preclude the development of the number of units otherwise allowed under the State Density Bonus Law and would significantly undermine the financial feasibility of providing the affordable units.

Waiver 5: The Applicant is requesting a waiver of Land Use Code 20.08.030 (R-1-6000 Setbacks) The R1-6000 development standards require a 20-foot setback from the front property line. Based on the size of the proposed Project’s site, proposed density, minimum street and parking space dimensions, observance of this standard would preclude the density bonus Project as designed by lessening buildable area. The proposed setback is

10.52-feet.

Parcel 2 - Affordable Housing:

Waiver 1: Waiver of Land Use Code 20.08.160 (Minimum Development Standards) The Multi Family development standards require a 10-foot rear setback. Based on the size of the proposed Project’s site, proposed density, and street, driveway and parking space dimensions, it would be physically impossible to observe the 10-foot rear setback. Doing so would preclude the density bonus Project as designed.

Waiver 2: The Applicant is requesting a waiver to the Central Healdsburg Avenue Plan’s vision to create a primary new street running north to south on the eastern portion of the proposed Project site The addition of a Item 4.b

primary new street across the proposed Project site would result in a significant loss of site coverage, directly impacting density by reducing the number of proposed units and would physically preclude the density bonus Project as designed.

Additionally, based on conversations with the City of Healdsburg during the One Stop Shop on January 30th, 2025, the City supported the idea of a path in lieu of a primary street as described in the Central Healdsburg Avenue Plan citing infrastructure challenges and the need for property acquisition. A Traffic Impact Study performed by W Trans on November 17, 2025, determined there is no operational benefit to extending University Street to Hudson Street, as envisioned in the CHAP, but there are several negative aspects to the proposal, including increased driving times and placing traffic near sensitive housing facilities.

Discussions with Public Works revealed that the proposed new street connection would require substantial reengineering at Mason Street, including modifications to existing infrastructure. Additionally, implementation of the proposed street would necessitate the City of Healdsburg acquiring property interests from two separate landowners in order to accommodate the alignment as currently envisioned.

Waiver 3: Central Healdsburg Avenue Plan Urban Frontage Development Standards The Applicant requests a waiver pursuant to Government Code §65915 of the Urban Frontage development standards of the Central Healdsburg Avenue Plan (CHAP), which, individually and cumulatively, would physically preclude construction of the residential project at the densities permitted under State Density Bonus Law:
✓ Entry spacing requirements limiting building entries to no more than 50 feet apart; ✓ Standards limiting blank wall widths to no more than 8 feet; ✓ Minimum first-floor floor-to-floor height requirements of 15 feet; and ✓ Requirements that at least 75% of the first-floor façade be glazed.

Application of these standards imposes a commercial frontage typology incompatible with residential construction, resulting in loss of structural efficiency, elimination of required shear walls, increased building height and cost, reduced unit yield, and an inability to achieve the density permitted under State Density Bonus Law (see Exhibit A).

Waiver 4: Usable Open Space
The Applicant requests a waiver of HMC 20.08.175, which requires a minimum of 200 square feet of usable open space per dwelling unit. Due to the parcel size, orientation and required parking areas, the affordable workforce housing will have less than 200 square feet of open space. Observation of this requirement would limit buildable area and density therefore physically precluding the density bonus Project as designed.

Continuing Care Retirement Community (CCRC) – Senior Living & Memory Care The proposed 4-story Type I-B steel frame, two-hour fire-resistive building atop an underground parking structure includes 67 senior living units, along with marketing, recreation, and guest amenity spaces located in the central and southern portions of the Project site. In the northernmost portion of the site, within the R-1-6000 residential zoning district, the Applicant proposes a single-story Type V-A wood-framed building featuring seven (7) bedrooms (six memory care and one manager bedroom) for a dedicated memory care center.

Item 4.b

GALLAHER SIGNATURE LIVING • GALLAHERSL.COM
In addition to senior housing, the Continuing Care Retirement Community (CCRC) will offer a comprehensive range of services and amenities designed for residents aged 62 and older. These include a state-of-the-art movie theater, library, salon, art studio, activity room, and card and game room, providing convenient access to entertainment, relaxation, and social engagement. Residents will also enjoy multiple dining venues featuring healthy, locally sourced ingredients. Wellness is a central focus of the community, with amenities including a fitness center, yoga and Pilates studio, and an on-site medical suite with visiting physicians.

The Project is thoughtfully designed to integrate both indoor and outdoor environments, providing over 500 square feet of usable open space per unit through a combination of private and common areas. Outdoor amenities include manicured grounds, a swimming pool, bocce ball and pickleball courts, fire pits, picnic areas, resident and chef gardens, landscaped walking and bicycle paths, and a pet park, all intended to promote active living and meaningful engagement with the surrounding environment.

The maximum building height is approximately XX feet, and the structure will be fully sprinklered.

Affordable Workforce Housing
The southeast portion of the Site will include 10 apartments with 10 private garages below. Each of the 10 apartments will be 100% affordable, offering housing to the workforce at varying levels of affordability. The apartments will include 8 affordable units for very-low-income individuals earning up to 50% of Area Median Income (AMI), 2 affordable units for low-to-moderate income individuals earning 80% to120% of Area Median Income (AMI), on-site laundry facilities, and office space.

GALLAHER SIGNATURE LIVING • GALLAHERSL.COM
The project is consistent with the goals and principles of the Central Healdsburg Avenue Plan by reinforcing a street network that respects the historic scale and fabric of Healdsburg while enhancing the arrival experience along Healdsburg Avenue into downtown. It supports the Plan area’s entrepreneurial and manufacturing legacy by encouraging new employment opportunities and strengthening existing businesses, while also fostering a diversity of housing options, including affordable housing. The project prioritizes alternatives to the private automobile through pedestrian- and bicycle-oriented design and provides safe, clear connections between downtown, the multi-modal transit center and the surrounding Plan area. In doing so, it promotes sustainable neighborhood development, respects private land ownership and market forces, and advances a broader vision for revitalization, economic vitality, and reduced blight within the Plan area.

Project Consistency with Goals and Principles of the Central Healdsburg Avenue Plan include:
• P1 Develop a street network consistent with existing scale/fabric of historic Healdsburg. • P2 Choreograph an enhanced arrival sequence via Healdsburg Ave to the Downtown. • P3 Build on the Plan area’s entrepreneurial and manufacturing legacy to create new employment. • P6 Foster a diversity of housing options.
• P7 Make alternatives to the private automobile easy.
• P8 Provide safe and clear connections from downtown to the multi-modal transit center, the surrounding Plan area and the Ward/Palm neighborhood.
• P10 Foster sustainable neighborhood development.
• P11 Respect private land ownership and market forces without losing a ‘bigger idea’.

Urban Frontages
The Central Healdsburg Avenue Plan identified urban frontages along Healdsburg Avenue and near the transit center where the highest levels of foot traffic are expected and some of the most desired sites exist. The proposed Project has incorporated many aspects and characteristics of the Central Healdsburg Avenue Plan and Urban Frontage type.

A defining feature of Gallaher Signature Living developments is the beautifully manicured and landscaped grounds.

This approach will be carried throughout the Healdsburg Continuing Care Retirement Community, where Urban Frontage guidelines will inform the landscape and design along Hudson Street.

Neighborhood Frontages
The northern and eastern borders of the proposed Project site are recognized by the Central Healdsburg Avenue Plan as a Neighborhood Frontage. Neighborhood Frontages are designed to emulate the character of Healdsburg’s residential neighborhoods, which features a mix of architectural styles and eras, a diverse but cohesive pattern of narrow lot widths, recessed or rear garages accessed from alleys or narrow side driveways, frequent front porches and entries, tree-lined sidewalks with landscaped planting strips, and landscaped front yards and fences. A varied range of housing types and densities can be accommodated within this frontage type. The Project proposes a singlestory craftsman style residence which will serve as the Memory Care Center and blend seamlessly with existing residential uses along Mason Street.

Existing Uses and Site Conditions
APN 002-291-033 is bordered by Mason Street and residential uses to the north, commercial uses to the east, and commercial uses, Hudson Street and the future SMART Station to the south. The Project Site, totaling 3.63 acres, has a General Plan Land Use designation of Medium Density Residential and Mixed Use and Zoning designation of both R1-6000 (R1) and Mixed Use (MU). Approximately 0.69 acres along the northern portion of the Site is designated R-1- 6000 (R1) with a maximum density of 6 du/ac and single-family dwellings, a permitted use. The central and southern portion of the Site, 2.94 acres, is designated Mixed Use (MU) with a maximum density of 16 du/ac. General Residential Care Facilities are a conditionally permitted use, while multifamily dwellings not part of a mixed-use development, are a permitted use within the Mixed-Use zoning. The proposed Project will be compact and efficient to make the best use of the site.

The Project site was formerly the home of Healdsburg Lumber Company’s offices and storage facilities. In April of 2023, the building materials retailer relocated to a larger site on Healdsburg Avenue and placed the vacant buildings at 359 Hudson Street for lease. The 4,000 square foot retail space, 5,600 square foot warehouse/flex space, 2,500 square foot retail/wine tasting/flex space, and 9,600 square foot warehouse, now known as “The Village on Hudson”, include tenants Getaway Adventures, Daisy Foundation, and vacant warehouse space.

Community, Adventure, and Education:

Residents will have many choices when it comes to social, educational, and wellness experiences through on-site gardens, lectures, and group travel experiences. Opportunities exist daily to connect with new friends, fellow residents and staff, learn a new skill, or give back through volunteerism.

Landscape
Low-maintenance and low-water-use will be the focus of the landscaping plan, blending luxury with sustainability.

Drought-tolerant native and ornamental plants will be used for resource-efficient and environmentally responsible development over its entire life cycle. Trees will be planted throughout to line the frontage and perimeters of the common areas, parking, and buildings, creating a buffer between the building and the street, as well as creating shaded gathering areas. In the center of the courtyard, a water feature, designed to recycle water, feeds into a rocklined stream that meanders through the gardens, collecting any irrigation overflow while promoting biodiversity attracting birds and pollinators. The irrigation system will be state-of-the-art, employing drip irrigation technology that delivers water directly to the roots, minimizing evaporation and ensuring efficiency. Weather sensors and timers will adjust the watering schedule based on current conditions, optimizing water usage every day of the year.

Sustainability
The buildings will comply with California’s Title 24 energy code. High performance Low E windows, optimal insulation levels and water heating systems will enhance energy savings and comfort. Plumbing fixtures will be low water use, with high performance low flow toilets, faucets and showerheads using less water than standard.

Framing lumber will be tested for moisture content before enclosure to ensure avoidance of future problems.

Healthy indoor air quality is enhanced using low VOC paints and adhesives along with fans that run continuously.

Carpeting and resilient flooring will be certified to Green Label Plus or FloorScore low-emitting standards. The Project does not propose any point sources of air or water pollutants.

Consistency with City of Healdsburg’s Housing Goals

WHEN PROPOSED DEVELOPMENT OR OTHER SITE WORK IS TO ENCROACH INTO THE TPZ OF A TREE, SPECIAL MEASURES MUST BE INCORPORATED TO ALLOW FOR SAFE AND HEALTHY CONDITIONS FOR PROTECTED TREES. ANY EXCAVATION, CUTTING, FILLING, PAVING, OR CONSTRUCTION OF THE EXISTING GROUND SURFACE WITHIN THE PROTECTED ZONE OF A TREE MUSH BE MINIMIZED. NO SIGNIFICANT ADVERSE CHANGE IN EXISTING GROUND LEVEL WILL OCCUR WITHIN THE DRIPLINE OF A PROTECTED TREE. DEVELOPMENT PROPOSALS MUST BE CONFIGURED TO RETAIN AS MANY HERITAGE AND SIGNIFICANT TREES AS POSSIBLE. CONSTRUCTION EQUIPMENT AND MATERIAL CANNOT BE STORED WITHIN TREE PROTECTION AREAS. NO OIL, GAS CHEMICALS, OR OTHER SUBSTANCES THAT MAY BE HARMFUL TO TREES SHALL BE STORED OR DUMPED WITHIN THE PROTECTED ZONE OR ANY OTHER LOCATION ON THE SITE FROM WHICH SUCH SUBSTANCES MIGHT ENTER THE PROTECTED ZONE. TRENCHING WITHIN THE TPZ OF TREES SHALL BE AVOIDED WHEREVER POSSIBLE. TRENCHING FOR UTILITIES MUST AVOID MAJOR ROOTS AND, IF AVOIDANCE IS IMPRACTICAL, TUNNELS MUST BE MADE BELOW ROOTS. TRENCHING IS TO BE CONSOLIDATED TO SERVE AS MANY UNITS AS POSSIBLE. TRENCHING WITHIN THE PROTECTED ZONE MUST BE DONE BY HAND TO MINIMIZE IMPACTS. ADDITIONAL MEASURES (COAs) MAY BE IMPOSED BY THE PLANNING AND BUILDING DIRECTOR TO PROTECT AND PRESERVE THE HEALTH OF THE TREES TO REMAIN, RELOCATED TREES, AND NEW TREES PLANTED TO REPLACE THOSE REMOVED. TREE PROTECTION MEASURES THE PROJECT SHALL ADHERE TO THE CITY'S HERITAGE TREE PROTECTION AND PRIVATELY OWNED STREET TREE ORDINANCE(s), IDENTIFIED ABOVE. THESE ORDINANCE STANDARDS PROVIDE PROTECTION MEASURES DURING CONSTRUCTION PERIODS THAT WOULD PROTECT BOTH HERITAGE TREES AND STREET TREES PROPOSED FOR PRESERVATION AND SHALL BE IMPLEMENTED BEFORE CONSTRUCTION COMMENCES. THE PROPOSED PROJECT IS EXPECTED TO INCLUDE A SITE PLAN INDICATING TPZ AREAS WHERE TREES WOULD BE PRESERVED AND PROTECTED DURING PROJECT DEVELOPMENT. THE FOLLOWING ADDITIONAL TREE PROTECTION MEASURES ARE RECOMMENDED TO MINIMIZE IMPACTS TO PROTECTED TREES: NO OPERATION OF EQUIPMENT OR VEHICLES, STORAGE OF MATERIALS, OR DISPOSAL OF WASTE MATERIALS SHALL OCCUR WITHIN THE DRIPLINES OF PROTECTED TREES. SITE CLEARING/STRIPPING SHALL BE LIMITED TO AREAS OUTSIDE PROTECTED TREE DRIPLINES WHEREVER POSSIBLE AND AS SHALLOW AS POSSIBLE WHERE NECESSARY WITHIN DRIPLINES. TEMPORARY PROTECTIVE FENCING SHALL BE PLACED AT THE DRIPLINES OF TREES OR AS SHOWN ON THE IMPROVEMENT PLANS. (IN SOME CASES, GRADING OR OTHER OPERATIONS MUST OCCUR WITHIN THE DRIPLINES, AND FENCING SHALL BE PLACED AS FAR AS POSSIBLE FROM THE TRUNKS AT THE LIMIT OF REQUIRED ACCESS. HOWEVER, AN ENCROACHMENT PERMIT IS REQUIRED FOR THIS EFFORT.) ANY PRUNING SHALL BE THE MINIMUM NECESSARY TO ACHIEVE HAZARD REDUCTION, PUBLIC SAFETY, CONSTRUCTION CLEARANCE AND TO IMPROVE TREE HEALTH. ALL PRUNING SHALL BE DONE ACCORDING TO ISA AND/OR AMERICAN NATIONAL STANDARDS INSTITUTE (ANSI) STANDARDS BY QUALIFIED PERSONNEL. PRUNING SHALL BE DONE BY ISA CERTIFIED TREE WORKERS OR CERTIFIED ARBORISTS OR UNDER THE DIRECT SUPERVISION OF A CERTIFIED ARBORIST. PRUNING FOR HAZARD REDUCTION SHALL INCLUDE: THE REMOVAL OF DEAD BRANCHES OR STEMS 2 INCHES IN DIAMETER AND LARGER (UNLESS NOTED OTHERWISE) AND BROKEN, WEAKLY ATTACHED OR CROSSING BRANCHES. STUBS OF BROKEN BRANCHES SHALL BE RECUT. PRUNING FOR CONSTRUCTION OR VEHICULAR CLEARANCE SHALL BE THE MINIMUM NECESSARY FOR THE SAFE OPERATION OF EQUIPMENT AND CONSTRUCTION ACTIVITIES. BRANCHES SHALL BE CUT BACK TO APPROPRIATELY SIZED LATERALS OR THE PARENT STEM. NO STUBS, BROKEN ENDS, FLUSH CUTS, OR WOUNDS ON TRUNKS OR BRANCHES ARE ACCEPTABLE. WHEN ACCESS MUST OCCUR FOR CONSTRUCTION WITHIN TPZs, A MONITORING ARBORIST SHALL BE PRESENT TO OBSERVE THE WORK AND MAKE RECOMMENDATIONS. AT THE COMPLETION OF CONSTRUCTION ACTIVITIES, THERE MAY BE AREAS AROUND PROTECTED TREES THAT REQUIRE TREATMENT TO ENSURE FUTURE TREE HEALTH. IN AREAS WHERE ROOTS ARE ENCOUNTERED AND BACKFILL WILL BE PLACED, ROTTS SHALL BE LEFT EXPOSED AS SHORT A TIME AS POSSIBLE TO AVOID DRYING OUT. AREAS WHERE SOIL HAS BECOME COMPACTED SHALL BE LOOSENED. IN DISTURBED AREAS, A 4-6-INCH-DEEP LAYER OF ARBOR MULCH (CHIPPED FRESH BARK, FOLIAGE, AND WOOD) SHALL BE PLACED WITHIN PROTECTED TREE DRIPLINES TO SERVE AS A PERMANENT TOP DRESSING. THE FCS ARBORIST RECOMMENDS MINOR MAINTENANCE (I.E., REMOVAL OF DEAD AND/OR DAMAGED GROWTH), CONDUCTED BY A QUALIFIED ARBORIST, TO THE FOUR PROTECTED HERITAGE TREES PROPOSED FOR PRESERVATION, UNDER THE CONDITION THAT THE APPLICANT RECEIVES PROPER PERMISSIONS FROM THE ADJACENT PROPERTY OWNERS. REFER TO THE CITY'S TREE PRESERVATION ORDINANCE FOR CONSTRUCTION STANDARDS, INCLUDING RECOMMENDATIONS FOR DELINEATING DESIGNATED TPZ AREAS, TREE PROTECTION BARRIERS, ROOT PROTECTION, SUBSTANCE CONTROL, TRENCHING, COMPACTION, TREE REMOVAL REGULATIONS, TREE MAINTENANCE, AND TREE REPLACEMENT/IN LIEU FEE MITIGATION. IN ACCORDANCE WITH THE CITY'S HERITAGE TREE PROTECTION AND PRIVATELY OWNED STREET TREE ORDINANCE(s), ADDITIONAL CONDITIONS OF APPROVAL MAY BE ISSUED IN CONJUNCTION WITH ANY TREE REMOVAL PERMITS. THESE CONDITIONS WOULD PROVIDE PROTECTION MEASURES PER THE CITY'S HERITAGE TREE PROTECTION AND PRIVATELY OWNED STREET TREE ORDINANCE(s) DURING CONSTRUCTION PERIODS THAT WOULD PROTECT BOTH HERITAGE TREES AND STREET TREES PROPOSED FOR PRESERVATION. THE PROPOSED PROJECT SHOULD FOLLOW ANY CONDITIONS OF APPROVAL PROVIDED BY CITY PERSONNEL.

Subject: Air Quality Analysis for the Proposed Healdsburg Continuing Care Retirement Community Project Located in Healdsburg, California

INTRODUCTION
At the request of Gallaher Signature Living (project applicant), FirstCarbon Solutions (FCS) prepared this memorandum to evaluate the potential air quality impacts associated with construction of the proposed Healdsburg Continuing Care Retirement Community Project (proposed project), located in Healdsburg, California.

PROJECT DESCRIPTION
The project site is located at 359 Hudson Street in the City of Healdsburg (City), in Sonoma County, California. The proposed project would develop approximately 3.61 acres of an approximately 3.63-acre site associated with Assessor’s Parcel Number (APN) 002-291-033. 1, 2 The project site is bounded by Mason Street and residential uses to the north; residential and commercial uses to the east; commercial uses, Hudson Street, and railroad tracks, as well as the future Sonoma-Marin Area Rail Transit (SMART) Station to the south; and residential uses to the west.

The proposed project would demolish approximately 21,700 square feet of existing uses and develop a Continuing Care Retirement Community (CCRC) consisting of one 4-story building with 67 luxury seniorliving units, two 2-story worker-housing apartment buildings totaling 10 units, one single-story memory1 Although the project parcel comprises 3.63 acres, the development area only consists of 3.61 acres. 2 While the modeling in Attachment A analyzed 3.60 acres, any difference in emissions would be negligible and would not materially change the outputs.

2 care residence with six memory care bedrooms, and a variety of indoor and outdoor recreational areas and amenities across the 3.61-acres.

APPLICABLE GENERAL PLAN POLICIES
The Healdsburg 2030 General Plan Policy Document contains the following policy that is relevant to air quality and would be required to be implemented by the proposed project. 3 NR-28 Require the use of Best Management Practices, such as those promulgated by the Bay Area Air District, during construction to minimize emissions.

ENVIRONMENTAL COMMITMENTS
In accordance with the City’s General Plan Policy NR-28, the proposed project would implement the following measures during construction to minimize emissions of dust and equipment exhaust. The measures shall be included in construction materials and demolition and grading permit applications.

Basic Best Management Practices (BMPs) for Constructionrelated Fugitive Dust Emissions • All exposed surfaces (e.g., parking areas, staging areas, soil piles, graded areas, and unpaved access roads) shall be watered twice per day, as needed. • All haul trucks transporting soil, sand, or other loose material off-site shall be covered. • All visible mud or dirt trackout onto adjacent public roads shall be removed using wet power vacuum street sweepers at least once per day. The use of dry power sweeping is prohibited. • All vehicle speeds on unpaved roads shall be limited to 15 miles per hour (mph). • All roadways, driveways, and sidewalks to be paved shall be completed as soon as possible.

Building pads shall be laid as soon as possible after grading unless seeding or soil binders are used.
• All excavation, grading, and/or demolition activities shall be suspended when average wind speeds exceed 20 mph.
• All trucks and equipment, including their tires, shall be washed off prior to leaving the site. • Unpaved roads providing access to sites located 100 feet or further from a paved road shall be treated with a 6- to 12-inch layer of compacted wood chips, mulch, or gravel. • Publicly visible signs shall be posted with the telephone number and the name of the person to contact at the Lead Agency regarding dust complaints. This person shall respond and take corrective action within 48 hours. The Bay Area Air District’s General Air Pollution Complaints number shall also be visible to ensure compliance with applicable regulations. 3 City of Healdsburg.

3 Tier 4 Final Equipment for Construction-related Exhaust Emissions
• All off-road diesel-powered construction equipment with a rated engine of 25 horsepower or greater shall be equipped with United States Environmental Protection Agency (EPA) Tier 4 Final engines, or equivalent emissions-control technology, and shall be properly maintained and operated in accordance with manufacturer specifications throughout the duration of construction activities. Onsite cranes (if applicable) and air compressors will be electric.

AIR QUALITY ANALYSIS
The project site is located within the Northern Sonoma County Air Pollution Control District (NoSoCo Air).

Air quality in NoSoCo Air is in attainment for all pollutants and falls below the applicable standards set in the National Ambient Air Quality Standards (NAAQS) and the California Ambient Air Quality Standards (CAAQS). NoSoCo Air has not adopted standards of significance for project emissions from individual development projects to use as guidance and recommends that projects use thresholds and guidance recommendations from the Bay Area Air Quality Management District (Bay Area Air District).

Therefore, the proposed project’s construction-related emissions were estimated and evaluated in accordance with the Bay Area Air District’s recommended methodologies and the thresholds of significance contained in the Bay Area Air District 2022 CEQA Guidelines. 4 Emissions were estimated using California Emissions Estimator Model (CalEEMod) Version 2022.1. CalEEMod provides a uniform platform for government agencies, land use planners, and environmental professionals to calculate emissions from land use development and linear projects in California. Use of CalEEMod is recommended by the Bay Area Air District.

Construction was assumed to begin in July 2028 and conclude in 2029. Construction activities would include demolition, site preparation and tree removal, grading, building construction, paving (of internal roads and parking areas), and application of architectural coatings. Construction emissions were modeled assuming construction would occur during 2027 and 2028. Although the project construction schedule has subsequently shifted to 2028 and 2029, construction emissions would be expected to decrease in later years due to ongoing improvements in equipment technology and increasingly stringent regulatory requirements applicable to construction equipment and fuels. Therefore, the emissions analysis represents a conservative, worst-case assessment of potential construction emissions. 4 Bay Area Air Quality Management District (Bay Area Air District). 2022.

4 CalEEMod provides default values for estimating construction emissions based on land use type, site size, and building size(s). These defaults were utilized in the analysis unless otherwise noted in the CalEEMod output report which is included in Attachment A.

Criteria Air Pollutant Construction Emissions
Construction Fugitive Dust
Construction-related activities, such as demolition, site preparation, grading, and material delivery and hauling, would result in fugitive dust emissions. Fugitive dust is recognized to impact local communities.

The City’s General Plan Policy NR-28 would require the use of BMPs, such as those promulgated by the Bay Area Air District, during construction to minimize emissions. Additionally, the Bay Area Air District bases the determination of significance for fugitive dust on whether feasible and effective control measures have been implemented or not. For a project to have a less than significant impact related to construction-related fugitive dust emissions, the Bay Area Air District’s Basic BMPs must be implemented.

Therefore, based on compliance with General Plan Policy NR-28, the proposed project would demonstrate a less than significant impact related to short-term construction fugitive dust emissions.

Construction Exhaust Emissions
Construction-related exhaust emissions for the proposed project were estimated in accordance with Bay Area Air District recommended methodologies and were compared against the Bay Area Air District’s thresholds of significance, as shown in Table 1. Table 1 shows the proposed project’s average daily construction exhaust emissions. As indicated in Table 1, construction exhaust emissions would be below the Bay Area Air District’s recommended thresholds of significance, and impacts would be less than significant.

5 Health Risk Assessment – Construction
According to the California Air Resources Board (ARB), some land uses are considered more sensitive to air pollution than others due to the types of population groups or activities involved. Heightened sensitivity may be caused by health problems, proximity to the emissions source, or duration of exposure to air pollutants. Children, pregnant women, the elderly, and those with existing health problems are especially vulnerable to the effects of air pollution. Accordingly, land uses that are typically considered to be sensitive receptors include residences, schools, child care centers, playgrounds, retirement homes, convalescent homes, hospitals, and medical clinics.

The project site is located within 1,000 feet of existing sensitive receptors that could be exposed to diesel emission exhaust during project construction. Construction emissions have the potential to result in significant health impacts due to emissions of diesel particulate matter (DPM), which is a toxic air contaminant (TAC), and fine particulate matter less than 2.5 microns in diameter (PM2.5). The nearest sensitive receptors are residents located immediately adjacent to the project site, including residences less than 10 feet from the southeastern and northwestern project boundaries. Residences are also located approximately 20 feet to the east of the northeastern project boundary. Worker receptors are located to the south and east of the project site; the nearest worker receptor is Fogbelt Brewing Company, approximately 60 feet to the south of the project site. In addition, the Pine Tree Preschool is located approximately 625 feet from the project site.

To evaluate potential construction-related impacts, a health risk assessment (HRA) was conducted using air dispersion modeling and exposure assumptions consistent with Bay Area Air District and Office of Environmental Health Hazard Assessment (OEHHA) guidance. The HRA quantifies potential cancer and non-cancer health risks to nearby sensitive receptors resulting from project-related construction emissions. Cancer risk is evaluated because long-term exposure to TACs may increase the likelihood of developing cancer, while non-cancer hazard impacts are evaluated to assess the potential for adverse health effects other than cancer. DPM is used as a surrogate TAC for evaluating cancer risk because diesel exhaust is a well-characterized source of TAC emissions and DPM serves as an indicator of the carcinogenic potency of diesel exhaust, consistent with OEHHA guidance. In addition, PM2.5 concentrations were evaluated in accordance with Bay Area Air District guidance because elevated concentrations of fine particulate matter have been associated with adverse health effects, including respiratory and cardiovascular impacts, independent of cancer risk.

DPM and PM2.5 emissions associated with project construction activities were quantified using CalEEMod. Emissions sources include off-road construction equipment and on-road mobile sources associated with construction activities, including worker trips, vendor deliveries, and haul trucks traveling on roadways within 1,000 feet of the project site.

The resulting DPM and PM2.5 emissions were modeled using the American Meteorological Society/EPA Regulatory Model (AERMOD) to estimate pollutant concentrations at sensitive receptors located within 1,000 feet of the project site. The modeling results were used to identify the Maximally Exposed Individual Resident (MEIR) and Maximally Exposed Individual Worker (MEIW).

Item 7.a

6 Cancer risk was evaluated at each of the sensitive receptors within 1,000 feet of the project site using the modeled DPM concentrations. Consistent with Bay Area Air District and OEHHA guidance, DPM was used as a surrogate TAC to evaluate the carcinogenic effects of diesel exhaust. Cancer risk, expressed as excess cancer cases per 1 million exposed individuals, was calculated at each receptor using the Hot Spots Analysis and Reporting Program, Version 2 (HARP2), which is the ARB software used to calculate health risks from TACs.

The analysis accounts for exposure occurring during the 13-month construction period and averages the resulting risk over a 70-year lifetime. For residential receptors, the risk assessment incorporated age sensitivity factors and assumed exposure beginning during the third trimester of pregnancy, consistent with OEHHA guidance. For preschool receptors, the risk assessment incorporated age sensitivity factors and assumed exposure beginning at age 18 months. 5 Worker cancer risk was based on exposure beginning at age 16 and incorporated a worker adjustment factor of 4.2 to account for the overlap between peak daytime construction activity and worker presence.

Chronic non-cancer health hazards were also evaluated using the annual average DPM concentrations predicted by AERMOD (EPA's preferred air dispersion model for estimating how air pollutants emitted from a source disperse in the atmosphere and what concentrations occur at nearby receptors). The chronic hazard assessment evaluates the potential for adverse long-term health effects other than cancer, such as impacts to organ systems or reproductive health, resulting from exposure to TAC emissions during construction.

Separately, annual average PM2.5 concentrations attributable to construction activities were evaluated at nearby sensitive receptors. Unlike the cancer and non-cancer health risk analyses, which assess health effects associated with exposure to TAC emissions, the PM2.5 analysis evaluates potential health impacts associated with elevated concentrations of fine particulate matter in ambient air from the proposed project’s construction activities.

Table 2 summarizes the proposed project's construction cancer risk, chronic non-cancer hazard index, and annual PM2.5 concentration impacts at the maximally exposed receptor locations. As shown in Table 2, the estimated cancer risk, chronic non-cancer hazard, and PM2.5 concentration impacts associated with project construction would not exceed the Bay Area Air District's applicable single source significance thresholds and impacts would be less than significant.

Source: Attachment A
As a residential project, the proposed project is not considered a source of TACs during operations because it would not include large stationary sources that generate TACs nor would the vehicles accessing the project site include a substantial number of diesel-fueled vehicles, which are sources of TACs. Therefore, operational-related impacts would be less than significant.

CONCLUSION
The analysis above demonstrates that air pollutant emissions and construction-related health risk impacts from implementation of the proposed project would not exceed the Bay Area Air District’s applicable thresholds of significance during construction. Operational TAC impacts would also be less than significant because the proposed residential project would not include large stationary TAC sources or a substantial number of diesel-fueled vehicles.

Notes:

Time of Day modeled using AERMOD’s hour‑ending convention and assumed 8am to 4pm.

Exhaust emissions from construction equipment modeled as an elevated volume sources with a release height of five meters and an initial vertical dimension of 1.4 meters. This represents the mid-range of the expected plume rise from frequently used construction equipment during daytime atmospheric conditions and follows modeling guidance from South Coast Air Quality Management District (South Coast AQMD), 2008. Final Localized Significance Threshold Methodology. Revised July 2008.

Emissions were modeled in AERMOD using a normalized emission rate of 1 g/s and scaled in HARP2 using the annual onsite DPM rate (lb/yr). A scalar of 4.2 was applied to apportion annual emissions to active construction working hours.

PM10 Exhaust is used as a surrogate for DPM and represents all on-site construction equipment exhaust.

Plume height and plume width and source release parameters are calculated internally by AERMOD using the EPA Haul Road Workgroup (2012) methodology (plume height = 1.7× vehicle height; plume width = road width + 6 m).

Truck height of 4.0 meters based on Bay Area Air District 2022 CEQA Guidelines (2023).

Modeled Annual Off-site PM10 Exhaust (DPM) Emissions 0.13 Notes:

PM10 = coarse particulate matter
Annual emissions were calculated for each year of construction and weighted by the fractional duration of construction activity within that calendar year to derive a total construction-period inventory. Total off-site DPM emissions were averaged over the full 13-month construction period, yielding an annual average emission rate of approximately 0.13 lb/yr.

A local roadway apportionment factor was applied to account for the fact that construction vehicles do not travel the entirety of their modeled trip length within the modeled area. The apportionment factor was derived by dividing the modeled roadway distance (1.23 miles, representing the length of roadway segments within the modeling area) by the shortest CalEEMod trip distance (6.0 miles, corresponding to hauling trips). This yielded an apportionment factor of approximately 0.21, which was applied to the annual average emission rate to produce the modeled roadway emission rate. This approach assumes that off-site vehicles may travel on any modeled segment and does not represent proportional allocation or actual routing.

Emissions were modeled in AERMOD using a normalized emission rate of 1 g/s and scaled in HARP2 using the annual on-site DPM rate (lb/yr). A scalar of 4.2 was applied to apportion annual emissions to active construction working hours.

PM2.5 = PM2.5 total which represents the sum of PM2.5 exhaust and PM2.5 dust, inclusive of brake wear, tire wear, and re-entrained road dust from construction vehicle travel.

The PM2.5 analysis is based on an evaluation of peak modeled annual average concentrations consistent with Bay Area Air District guidance (2023, Appendix E). Annual average PM2.5 concentrations were evaluated for the year of highest annual construction emissions.

A local roadway apportionment factor was applied to account for the fact that construction vehicles do not travel the entirety of their modeled trip length within the modeled area.
