Annual Water Supply and Demand Assessment Procedures
This section presents the procedures that will be used by Sonoma Water to conduct an annual water supply and demand assessment (annual assessment). The annual assessment is required to be submitted annually to DWR beginning on July 1, 2022. The assessment forecasts near-term water supply conditions (12 months) to ensure shortage response actions are triggered in a timely manner. The annual assessment will provide a description and quantification of each source of Sonoma Water’s water supply compared to water demands for the current year and one subsequent dry year. The following subsections describe the decision-making process and data and methodologies. Sonoma Water may modify this procedure based on its experiences that it will gain from the development of the annual assessment.

Decision-Making Process
This section presents the decision-making process and timeline (see Table 1) that Sonoma Water will use each year to determine its water supply reliability. The assessment will be conducted annually and completed by July 1. Sonoma Water will conduct an annual assessment that follows the steps described below.

1. Develop draft annual assessment. Sonoma Water staff will compile the draft annual assessment. The draft annual assessment will document the evaluation of water supply conditions, considering projections of the demand for Sonoma Water provided by the customers by February 1. Sonoma Water staff will start conducting the assessment prior to the January Decision 1610 trigger point and then thereafter at the middle of each month prior to the trigger point at the beginning of each month through June. Decision 1610 is described later in this assessment procedure description.

2. Submit draft annual assessment report to the customers. The draft annual assessment will be submitted and presented to the TAC ad-hoc committee at the April meeting. An initial determination will be made regarding the potential for a water shortage condition to occur.

3. Receive review comments. The customers will present their review comments including their updated demands and local supply projections at the May TAC meeting.

4. Submit final annual assessment to the TAC. The final annual assessment will be submitted and presented at the June TAC meeting. The annual assessment may be presented to the WAC.

Sonoma Water will coordinate with the customers to identify if any water supply gaps exist for each customer when considering both Sonoma Water supplies and local supplies.

5. Optional presentation of the annual assessment to the Board of Directors. The annual assessment may be included in the agenda for Sonoma Water’s Board of Directors regular meeting, particularly if a shortage is anticipated or if an existing shortage condition is to be ended.

6. Submit annual assessment to DWR. Sonoma Water will submit the annual assessment report to DWR by July 1 of each year.

Data and Methodologies
This section presents the key data inputs and assessment methodology that will be used to evaluate Sonoma Water’s water supply. The evaluation criteria, water supply, unconstrained demand, water supply, planned water use, infrastructure considerations, and other factors are described.

Evaluation Criteria. Evaluation criteria are determined by the supply source conditions and factors that impact the condition of each supply source. The criteria include the key data inputs and the constraints that are imposed on the water supplies.

The key data inputs that are used by Sonoma Water staff to forecast water supply for the remainder of the current year and a subsequent dry year include the items described below. • Unconstrained customer demand. Current and subsequent year unconstrained demand for each of Sonoma Water’s wholesale customers considering weather, growth, and other influencing factors.
• Russian River operations. Current reservoir releases from Lake Sonoma and Lake Mendocino, including anticipated releases to meet in-stream flow requirements and water demands and based on reservoir curves and forecast informed reservoir operations (FIRO) decision support tools.
• Hydrology and watershed conditions. Lake Sonoma and Lake Mendocino cumulative inflows and storage levels, and soil moisture and snowpack.
• Potter Valley Project inflows. Lake Pillsbury storage levels and observed and projected project transfers. Decision 1610 contains trigger points at the first of each month from January to June to establish a hydrologic index based on cumulative inflows into Lake Pillsbury on the Eel River.

Sonoma Water’s Russian River water supply is controlled and influenced by a variety of agreements and decisions. There are several constraints, requirements, and restrictions on water supply that will be considered as part of the assessment of the available water supplies, as follows. • Lake Sonoma storage level. Minimum 100,000 ac-ft Lake Sonoma storage level and 30 percent delivery deficiency. This key constraint is described later in this section.

Agenda Item #8.1:

Page 287 of 454 ends

• Lake Mendocino storage level. Having a sufficient supply of water in Lake Mendocino in the fall is of critical importance to the salmonid species in the Russian River. • Minimum instream flow requirements. The minimum instream flow schedule varies based on the hydrologic classifications of Normal, Dry, and Critical water supply conditions as defined in Decision 1610. Minimum instream flow requirements for the Russian River and Dry Creek are met by releases from Coyote Valley Dam and Warm Springs Dam. • Maximum flow releases from Warm Springs and Coyote Valley Dams. • US Army Corps of Engineers’ flood control operations criteria. • The Russian River Biological Opinion. The Russian River Biological Opinion places certain terms and conditions on the Sonoma Water with respect to its water supply operations.

Sonoma Water’s water rights permits include a provision that requires Sonoma Water to impose a 30 percent deficiency in deliveries from the Russian River to its service area when Lake Sonoma storage levels drop below 100,000 ac-ft before July 15 of any year. This deficiency must remain in effect until “(1) storage in Lake Sonoma rises to greater than 70,000 ac-ft subsequent to December 31 after having fallen below that level, or (2) permittee has projected, to the satisfaction of the Chief, Division of Water Rights, that storage at Lake Sonoma will not fall below 70,000 ac-ft, or (3) hydrologic conditions result in sufficient flow to satisfy permittee’s demands at Wohler and Mirabel Park and minimum flow requirements in the Russian River at Guerneville.”
Water Supply. This subsection provides a brief overview of Sonoma Water’s supply sources. These water supply sources will be described, and estimates made of the availability of supplies in the annual assessment. Sonoma Water’s most recent Urban Water Management Plan provides a more detailed description of the water supplies.

The Russian River provides most of Sonoma Water’s water supply with groundwater supply from the Santa Rosa Plain as a secondary source. Sonoma Water diverts water from the Russian River near Forestville and conveys the water via its transmission system to its customers. The surface water is subject to varying quantities of available supply based on hydrologic conditions and sometimes regulatory restrictions.

Almost all of Sonoma Water’s customers have other water supplies, in addition to those provided by Sonoma Water, which include local surface water, local groundwater, and recycled water. These local supplies will not be included in the assessment. Each customer will develop its own assessment of their available supplies.

Two federal projects impound water in the Russian River watershed: the Coyote Valley Dam on the Russian River east of the City of Ukiah in Mendocino County (forming Lake Mendocino), and the Warm Springs Dam on Dry Creek (a tributary of the Russian River). The Potter Valley Project diverts water from the Eel River into the Russian River watershed.

Unconstrained Customer Demand. The assessment will present the current year unconstrained demands from Sonoma Water’s customers, considering weather, growth, and other influencing factors.

The unconstrained water demands will be provided by the customers.

Agenda Item #8.1:

Page 288 of 454 ends

Planned Water Use for Current Year Considering Dry Subsequent Year. The assessment will present an evaluation of the amount of anticipated water supplies for the current year as well as how the supplies will be used, while anticipating that the following year will be dry.

The annual assessment will be based on evaluating the key data inputs to determine the water supply reliability. The methodology to develop the annual assessment will follow the general approach described below.

1. Quantify current year water supply. The available water supply from all water supply sources will be estimated for the current year based on the data inputs, evaluation criteria, and hydrological and regulatory conditions in the current year. Sonoma Water staff will evaluate water supply conditions beginning at least mid-month prior to each of the January to June Decision 1610 trigger dates to determine whether anticipated conditions at the trigger dates warrant any actions by Sonoma Water. The projections of the water supply will be expressed as a range and based on the results of operations modeling of the Russian River system consisting of the statistical evaluation of multiple scenarios. The model is described later in this subsection.

Figure 1 presents the key considerations for the assessment of Russian River supply conditions.

2. Quantify subsequent year supply. The subsequent year water supplies will be estimated by assuming a dry year. Sonoma Water may base the estimate of dry year water supplies on the historical hydrologic record or some other approach.

3. Identify infrastructure constraints. The existing infrastructure capabilities and plausible constraints as they impact Sonoma Water’s ability to deliver supplies to meet expected customer water use needs in the coming year will be considered.

4. Quantify unconstrained water demand. The unconstrained water demands for all the customers will be provided by the customers.

5. Compare projected water supplies to demands. The water supplies identified in the annual assessment will represent the water demand that can be met while maintaining adequate storage in Lakes Mendocino and Sonoma.

6. Identify and quantify anticipated water supply shortages, if any. The forecast of water supplies in comparison to water demands will identify and quantify any anticipated water shortages. The forecast will be coordinated with the customers. Depending on the extent of the forecast shortage, the appropriate shortage stage will be selected. If the forecast is for a wet season, there would be no concerns. If the season was dry in the early wet season, there would be a potential concern and river flows and reservoir levels would be monitored more closely.

Depending on the extent of precipitation in the latter portion of the wet season, the forecast could be changed to no concern or to an anticipated shortage.

7. Extent of water shortage. The water shortage may be caused by the requirement to reduce supplies by 30 percent based on the Lake Sonoma level. Sonoma Water may request voluntary reductions and perhaps mandatory reductions before Lake Sonoma levels reached 100,000 ac-ft by July 15in accordance with the applicable provisions of the Restructured Agreement and consistent with the defined shortage stages . If a shortage is identified, the water shortage allocation methodology will be used to allocate the reduced supply to each customer. Each of Sonoma Water’s customers will develop their own annual assessments that will include estimates of their projected quantity of local water supplies.

Agenda Item #8.1:

Page 289 of 454 ends

The forecast of the amount of available water supplies will be developed by Sonoma Water using the Russian River System Model (RR ResSim). The model is used as a planning tool to simulate the effects of various climatic conditions, levels of demand, and operational criteria on the water supply available for use by Sonoma Water and others.

Infrastructure Considerations. The annual assessment will include an evaluation of how infrastructure capabilities and constraints may affect Sonoma Water’s ability to deliver supplies to meet expected customer water use needs in the current year.

Other Factors. The annual assessment will describe any other locally applicable factors that could influence the amount of available water supplies.

Select the Drought Response Actions you would like to include in your estimated savings calculations. For each selected action, use the default end use savings estimates and implementation rates or input your own values. The "End Use Savings" estimates the percent water use reduction that could occur at a particular end use as a result of a specific action. The "Implementation Rate" refers to the estimated percentage of accounts that will implement a specific action. The water savings potential at each end use is capped based on the assumed distribution of end use water demands shown in the pie charts above. A dash (--) indicates that professional judgement was used to establish the default value, or that savings are expected to be accounted for as part of a Public Information Program; additional basis for the default values are included in the User Manual.

Select the Drought Response Actions you would like to include in your estimated savings calculations. For each selected action, use the default end use savings estimates and implementation rates or input your own values. The "End Use Savings" estimates the percent water use reduction that could occur at a particular end use as a result of a specific action. The "Implementation Rate" refers to the estimated percentage of accounts that will implement a specific action. The water savings potential at each end use is capped based on the assumed distribution of end use water demands shown in the pie charts above. A dash (--) indicates that professional judgement was used to establish the default value, or that savings are expected to be accounted for as part of a Public Information Program; additional basis for the default values are included in the User Manual.

A Resolution Adopting the 2025 Urban Water Management Plan and Water Shortage Contingency Plan
Summary
The City's 2025 Urban Water Management Plan (UWMP) and included Water Shortage Contingency Plan (WSCP) was prepared in accordance with the state of California Urban Water Management Planning Act (the Act), California Water Code Sections 10610 through 10657 and the 2025 Urban Water Management Plan Guidebook (made available in January 2026). The Act requires every urban water supplier providing water for municipal purposes to more than 3,000 connections, or supplying more than 3,000 acre-feet of water annually, to adopt and submit a plan every five years to the Department of Water Resources (DWR). There have been no requirement changes since 2020.

The purpose of the UWMP and WSCP is to consolidate information regarding water supply and demand, provide public information, and improve state-wide water planning. In conjunction with the updates to the UWMP and WSCP, the community is given the opportunity to give input on the City's updated plans. Drafts of both the UWMP and WSCP were uploaded to the website on May 27th, 2026 for public viewing. A notice of hearing was published in the Sonoma Index Tribune on June 5th and June 12th, 2026. Comments and corrections raised at the public hearing will be incorporated into the document, and the summary of the comments will be included in the appendix of the final UWMP and WSCP submitted to the Department of Water Resources. The UWMP and WSCP must be adopted by June 30th, 2026, and filed with DWR by July 1, 2026, and sent to the State Library.

While it is the 2025 UWMP, it is being considered and adopted in 2026 because it utilizes data for a full reporting cycle - from 2020-2025, which requires a full and complete data set. A copy of the signed resolution of the Plan Adoption is submitted to DWR.

Adoption of the 2025 UWMP and WSCP is exempt from the California Environmental Quality Act (CEQA) and the State Guidelines pursuant to CEQA Guidelines section 15601(B)(3) as it can be seen with certainty that there is no possibility that adoption of the 2025 UWMP may have a significant effect on the environment.

Recommended Council Action
Adopt a Resolution Adopting the 2025 Urban Water Management Plan and Water Shortage Contingency Plan.

Alternative Actions
Council discretion.

Review, Discussion, and Potential Approval of a Public Art Donation and Installation Submitted by Peter Hassen
Summary
Background:

City staff received a proposal from Sonoma artist, Peter Hassen, on May 5, 2026, to donate a sculpture to be included as part of the City's permanent public art collection. The proposed artwork is a 96-inch Corten steel sculpture comprised of three intersecting circular forms featuring imagery of bees, birds, and frogs. The sculpture was previously displayed in Plaza Park as a temporary installation for approximately six months in 2022. The sculpture is intended to promote reflection on biodiversity, environmental stewardship, and the interconnectedness of natural systems.

City Council adopted the Public Art Policy and Procedures on December 18, 2024. Under the policy, the Cultural and Fine Arts Commission is responsible for reviewing public art proposals, evaluating proposals based on location and audience, aesthetic quality, site appropriateness and financial impact, and recommending acceptance of gifts and loans of artwork to the City Council. Final review and acceptance of Public Art Donations remains with the City Council.

Discussion:

The proposal has been reviewed for consistency with the City's Public Art Policy and staff finds that the proposal satisfies the submission requirements and evaluation criteria established within the policy. The applicant has submitted the required visual documentation, artwork description, installation details, cost information, and maintenance plan.

The sculpture is fabricated from half-inch Corten steel, weighs approximately 1,600 pounds, and is designed for long-term outdoor installation with minimal long-term maintenance requirements. Recognizing this piece is intended to be in a well trafficked public space, the installation details provide that the piece is sturdy and can withstand regular community interaction. The artist has shared that they are available to provide technical assistance and advise staff on transportation, installation, and maintenance needs as they arise.

The artist has identified the southeast quadrant of the Sonoma Plaza as a preferred installation location. The proposal identifies placement on the south side of the pedestrian pathway in that quadrant, though the artist has expressed support for the north side of the pedestrian walkway as well, which may provide a more suitable space for installation and visibility. Given the anticipated long-range planning efforts for the Plaza and park system, staff recommends the council consider an initial pilot installation period prior to determining a permanent location. This approach would allow the community to provide feedback on the artwork's placement while giving staff and the Cultural and Fine Arts Commission additional time to evaluate future public art opportunities and develop a comprehensive strategy for public art within the City's parks and public spaces.

Agenda Item #9.2:

Page 366 of 454 ends

While the artwork is a direct, unrestricted donation to the City, the City will incur costs associated with transportation, foundation construction and installation, any necessary engineering review, and future maintenance, which would be funded through the Public Art Fund allocation within the adopted operational budget. The artist has shared that they are available to provide technical assistance and advise staff on transportation, installation, and maintenance needs as they arise.

Cultural and Fine Arts Commission Review
On June 9th, 2026, the Cultural and Fine Arts Commission reviewed and discussed the proposed sculpture at their regular meeting. The commission provided a formal recommendation (5-0, 2 absent) to accept the donation and move forward with installation in the southeast quadrant of Plaza Park, under the framework of an initial pilot period. They also provided the following considerations to staff:
 Consult with artist on final placement, but recommend using the open grass area, within the southeast quadrant of the Plaza, near the intersection of First Street East and East Napa Street
 Consider options for a moveable concrete base that would provide the aesthetics of a more permanent installation, while still providing flexibility to move locations  Based on installation location and materials, involve engineering review and documentation where necessary
 Evaluate whether adding up lighting is feasible to illuminate the piece without causing issues to wildlife patterns
 Work with artist on proper orientation of the sculpture; Initial preference is to place bees disk at the top of the placement
 Consider the addition of an education plaque to highlight the artist and provide education on the public art program
If the Council determines to accept the donation, the conditions noted within Section 6 (Conditions of Acceptance) within the Public Art Policy and Procedures document will be met prior to transfer of ownership. Additionally, upon acceptance and prior to installation, staff will collaborate with the artist for any necessary engineering review and refinement of installation details, based on the Council's determination of location.

Recommended Council Action
Review the proposed donation of Peter Hassen’s sculpture and approve the public art donation and installation, including acceptance of the artwork and its future installation, subject to final site selection and verification of ownership documentation.

Alternative Actions

1. Approve the donation, but with different or modified installation conditions and/or location(s);

2. Request additional information from staff and/or the artist to be brought back at a future meeting;

3. Decline to accept the proposed donation.

Financial Impact
The artwork is being offered as a donation to the City. City costs will include transportation, foundation construction, installation, any necessary engineering review, and long-term Agenda Item #9.2:

Sonoma Public Art Proposal
Cycle 3: Extinction Sculpture
Donation to the City of Sonoma
By Peter Hassen
1 OVERVIEW

1. Visual documentation: See attachment #1

2. Description:
a. Cycles 3 is a corten steel sculpture that is 96” “in the round” (96”X96”X96”). It is made of three intersecting 96” round disks and each is cutout with a different pattern, representing Bees, Birds and Frogs.

These disks are welded together at right angles so that it “sits” on three contact points on the ground in a very stable geometry. The sculpture wants to sit on a hexagonal concrete pad (see attachment #2), but temporarily can sit on a steel plate if on display, or for temporary storage can just sit on grade. Total weight is 1600 pounds. It anchors permanently via welds at the three “foot” touch points.

3. Site Plan: See attachment #3

4. Installation Details:
a. Installation starts with a flatbed truck here at my property on Petaluma ave. I rent a “Gradall” forward lift crane and easily lift the piece onto the truck. At the installation site the city’s forward lift crane lifts the piece and sets it onto the concrete pad. A welder then welds the sculptures “feet” to the exposed bolt heads. . . and it’s complete.
b. See attachment #4 for more details

5. Cost Estimate: See Budget attachment #5

6. Conservation and Maintenance Plan:
a. The artwork is constructed of 1/2” corten steel with a rust patina. As such it is virtually indestructible and requires very little maintenance.

Periodically I sweep cobwebs off it with a broom, and once every 6 months I wash it with a metal brush and soap solution to remove the bird droppings (although this may not be a problem in the city). While any sculpture faces vandalism risk, this sculpture sat in the Sonoma Plaza for 6 months without any such occurrence. If vandals spray paint it, it can be pressure-washed with a paint-on graffiti-removal solution to clean it up.

The expected lifespan is hundreds of years as corten achieves a rust patina, then ceases to rust further. While the sculpture runs the risk of being climbed, it’s sturdiness of design ensures that even several adults hanging on it will not hurt it.

The site plan is to be determined. In my best world scenario, it would live in a highly visible location where people gather weekly, and the sun is able to shine through it and cast interesting shadows on the ground below. I realize that this is a sensitive topic, but the Sonoma Plaza is the ideal location. It has already visited there for six months in 2022 for the “A Delicate Balance” sculpture exhibit. I wish I had a dollar for everyone who expressed a hope to me that it would live there again. This section will be revisited after consultation with the City.

PUBLIC ART POLICY AND PROCEDURES
NOVEMBER 19, 2024
3 1.0 Introduction and Overview

1.1 Introduction
This Public Art Policy and Procedures (Policy) sets forth a comprehensive framework for the administration and management of the City of Sonoma's Public Art Program. It defines the roles, responsibilities, and procedures involved in selecting, installing, maintaining, and deaccessioning public artworks while ensuring a transparent and equitable process. The Policy also outlines funding mechanisms, guidelines for accepting gifts and loans of artwork, and strategies for enhancing Sonoma's cultural and artistic identity.

The goal of this policy is to promote the integration of art into public spaces, foster community engagement, support artists, and enhance the quality of life for Sonoma’s residents and visitors. Through collaboration with artists, City staff, and the Cultural and Fine Arts Commission, the Public Art Program aims to create a lasting cultural legacy that reflects the history, diversity, and creativity of Sonoma.

Key elements covered in this policy include:
● Procedures for the selection of artists and artwork
● Evaluation criteria for public artworks
● Guidelines for gifts, loans, and acquisitions of artwork ● Maintenance and preservation of public art
● The deaccessioning process for artwork that is no longer suitable for display This Policy serves as a guide for all stakeholders involved in Sonoma’s Public Art Program and emphasizes the City’s commitment to becoming a recognized art destination while integrating art into the daily lives of the community. By broadening the scope to include temporary installations and programs, the City of Sonoma ensures that its public art offerings remain vibrant, diverse, and responsive to the evolving cultural landscape.

1.2 Policy Statement
The purpose of the Public Art Program is to serve as a catalyst for urban beautification, cultural enrichment, and social cohesion, enhancing the experiences of residents and visitors while promoting economic development and establishing Sonoma as a vibrant art destination. The Public Art Program will also actively engage the community and local artists to reflect the cultural diversity and identity of Sonoma.

To make public art an integral element of the City of Sonoma’s built and cultural environment, the City will establish and maintain a program dedicated to the creation, acquisition, and integration of public artwork in collaboration with developers, artists, and community stakeholders.

The Cultural and Fine Arts Commission will report annually to the City Council on the status, impact, and achievements of the Public Art Program, including both temporary and permanent installations.

7 2.0 Types of Art Installations

2.1 Permanent Art Installations
Permanent public art installations are artworks intended for long-term or indefinite display in public spaces. These pieces contribute to the cultural and aesthetic landscape of the City and may include sculptures, murals, monuments, and other enduring forms of art. Permanent artworks are funded through the Public Art Fund and follow a structured approval and installation process to ensure they align with the City's public art goals.

2.1.1 Conditions Governing Permanent Art Installations
a. Approval Process: Artworks proposed for City-owned property must be reviewed by the Commission and approved by the City Council. The review process includes assessing the artwork's alignment with City goals, aesthetic values, and public safety.
b. Installation and Maintenance: The City is responsible for the installation of artworks on City-owned property, with ongoing maintenance covered under Section 4.0: Ownership and Maintenance. Maintenance plans are developed during the installation phase and reviewed periodically to ensure the artwork remains in good condition.
c. Site Selection: The identification of potential sites follows the criteria outlined in Section 7.0: Site Selection. Considerations include visibility, public access, and integration with existing infrastructure.
d. Deaccessioning: Should a permanent artwork become unsuitable for display due to damage, obsolescence, or other factors, the deaccessioning process as outlined in Section 4.0: Ownership and Maintenance will be followed. This process involves evaluating the artwork's condition, considering alternatives, and making recommendations for removal or replacement.

2.2 Temporary Public Art Installations
Temporary public art installations are works intended for display over a limited time period, typically ranging from a few weeks to one year, but may remain in place for up to 19 years.

These installations include sculptures, murals, digital or performance-based art, and sitespecific interventions designed to engage the public. Temporary artworks may be loaned to the City, commissioned by the Public Art Program, or created with the intention of natural decomposition or scheduled replacement.

9 3.0 Special Situations and Considerations

3.1 Conflict of Interest of Panelists and Committee Members Any persons who would receive financial gain from the selection of artists or artworks are ineligible to serve on an Artist Selection Ad Hoc Committee or Panel. Such persons include gallery dealers, artists’ agents, and brokers. Relatives of the Commission, or any persons who have a personal relationship with competing artists that could be identified as a conflict of interest, are not eligible to serve on Artist Selection Ad Hoc Committees or Panels. Any artist selected to serve on the Artist Selection Ad Hoc Committee or Panel is precluded from having his/her work considered for any public art project during his/her time of service. City of Sonoma staff is ineligible to apply for public art projects or commissions.

3.2 Artwork on Private Property/Public-Private Partnerships Public art placed on private property as part of public-private partnerships must comply with specific agreements between the City and the property owner(s). These partnerships can expand the reach of public art but require clear legal and operational guidelines to ensure public access and proper maintenance.
a. Public Access: Any public art placed on private property must be accessible to the public during agreed-upon hours. Signage indicating public accessibility should be installed when appropriate.
b. Maintenance Responsibility: A written agreement will outline the responsibilities for ongoing maintenance, repair, and conservation of the artwork. In most cases, the property owner will bear these responsibilities, with periodic inspections conducted by the appropriate City department(s) or a designated party to ensure compliance. c. Ownership and Liability: Ownership of the artwork will be clearly defined in the agreement, along with terms for insurance, liability, and damage. If ownership is transferred to the private entity, clauses will cover future removal, sale, or relocation. d. Legal Agreements: All parties must sign a formal agreement that outlines these conditions, ensuring that the artwork will remain publicly accessible and maintained to agreed standards. The agreement will also specify conditions for terminating the partnership.

3.3 Deaccession or Removal of Artworks
This process ensures that decisions are made transparently and with due consideration for the cultural, historical, and artistic value of the work. a. Criteria for Deaccession: Artwork may be considered for deaccession if it:
i. Is irreparably damaged or deteriorated.
ii. Poses a safety risk to the public.
iii. No longer aligns with the values or needs of the community. iv. Needs to be relocated due to development or significant site changes.

Agenda Item #9.2:

Page 386 of 454 ends

CITY OF SONOMA CULTURAL & FINE ARTS COMMISSION

PUBLIC ART POLICY AND PROCEDURES
NOVEMBER 19, 2024
10 b. Evaluation Process: The Commission will review and evaluate any proposal for deaccession, with input from stakeholders, including the artist (if possible), the community, and other City departments.
c. Public Involvement: When appropriate, public input will be solicited before the final decision on deaccession or removal is made. The Commission will facilitate this process through public hearings or forums.
d. Disposal or Relocation: If deaccession is approved by City Council, the City will determine the appropriate method for removing the artwork. Options may include selling, donating, returning to the artist, or relocating the artwork to another site.

The method of disposal will align with City policies and legal requirements.

3.4 Emergency Removal or Temporary Relocation
In the event of an emergency, public art may need to be removed or temporarily relocated to protect the artwork or ensure public safety. Emergency removal is guided by the need to preserve the integrity of the art while addressing urgent conditions. a. Emergency Criteria: The City may authorize the emergency removal or relocation of artwork in cases such as:
i. Natural disasters (floods, earthquakes, fires, etc.). ii. Construction or development that threatens the safety or visibility of the artwork.
iii. Immediate safety hazards to the public or the artwork itself. b. Notification and Coordination: City staff will coordinate with the necessary City departments to ensure that emergency removal or relocation is carried out safely and efficiently. When possible, the artist will be notified and consulted during the process. c. Restoration and Reinstallation: Once the emergency conditions have been resolved, the artwork will be restored and reinstalled if feasible. If the artwork cannot be restored or the original site is no longer viable, a new location may be selected following the criteria in Section 7.0: Site Selection.

3.5 Controversial or Challenging Content
Public art is a reflection of diverse artistic expression and public values. However, some artworks may elicit controversy due to their content or subject matter. This section establishes the guidelines for addressing public concerns and ensuring that public art serves the community in a thoughtful and inclusive manner.
a. Public Feedback: When public concerns or objections are raised about specific artworks, the Commission will provide an open forum for discussion. Public hearings or community feedback sessions may be organized to gather input from residents and stakeholders.
b. Criteria for Evaluation: In cases of controversy, the artwork will be evaluated based on:
i. Alignment with the City’s mission and values.
ii. The artistic merit and integrity of the work.

4.2 Ownership of Temporary Artwork

4.2.1 Artwork Retained by the Artist or Sponsoring Organization These installations are either on loan or sponsored by an artist or an organization, with the artist or organization retaining ownership and full responsibility for maintenance, deinstallation, and site restoration upon removal. However, in certain circumstances, these installations may be eligible to receive Public Art Funds to help offset associated costs, particularly if they align with the goals of the City’s Public Art Program. a. Ownership of the artwork remains with the artist or sponsoring organization throughout the installation period.
b. The artist or sponsoring organization is generally responsible for all associated costs, including transportation, installation, maintenance, insurance, and removal. However, the use of Public Art Funds to offset these costs may be recommended by the Commission and is subject to approval by the City Council. c. The artist or sponsoring organization is responsible for addressing any damage or required repairs to the artwork or the installation site, including any impact on infrastructure such as irrigation systems, underground electrical components, sidewalks, or similar facilities during the display period. d.

15 5.0 Funding and Financial Guidelines

5.1 Public Art Fund
A special fund, designated as the "Public Art Fund," is established for the deposit of gifts, bequests to the City for public art, and other funds for works of art in accordance with the Public Art Program. The Public Art Fund is used exclusively as a means of isolating and identifying all monetary transactions pertaining to the City Public Art Program.

The City Manager, or their designee, is the custodian of the Public Art Fund.

A portion of the Public Art Fund shall be appropriated for administrative costs associated with the selection of public art and for maintenance of works of public art.

Staff salaries will not be funded from the Public Art Fund, except for repair and maintenance costs, as noted in the Appropriate Use of Public Art Program Funds Section 5.6 of this Policy if performed by City employees, and as otherwise authorized by the Commission in consultation with the City Manager.

Appropriation of funds to support the Public Art Program shall be made to the Public Art Fund, consistent with the City’s budget cycle, Capital Improvement Plan, and major capital projects identified by the City Council.

5.2 Funding Basis
Public Development Projects: For all public city-owned development projects with a total building permit valuation cost exceeding $250,000, the City shall allocate an amount equal to 1% of these costs for the acquisition of public art for placement within the City. In the case of public projects with federal and/or state matching requirements or grant funding, the 1% allocation will apply solely to the City's portion of the project funding.

Annual City Allocation: Each fiscal year, an amount equal to one-quarter of one percent (0.25%) of the City of Sonoma’s budgeted General Fund expenditures shall be appropriated to the Public Art Fund. This allocation will be capped at $25,000 per fiscal year. If the City’s financial situation does not allow for this allocation, the City Council reserves the right to waive or reduce it, with such a decision requiring the adoption of a resolution detailing the findings for the waiver.

5.3 Calculation Base
The amount of the annual appropriation for art shall be equal to 0.25% of annual General Fund expenditures, capped at $25,000 per fiscal year, plus one percent (1%) of the estimated construction costs for eligible City-owned construction projects with total building permit valuation costs exceeding $250,000, if allowed by the specified project funding source(s).

Agenda Item #9.2:

CITY OF SONOMA CULTURAL & FINE ARTS COMMISSION

PUBLIC ART POLICY AND PROCEDURES
NOVEMBER 19, 2024
16 5.4 Appropriation
At the time an eligible construction project is proposed, the City staff shall calculate and include a budgeted line item for a contribution to the Public Art Fund. Fund transfers to the Public Art Fund will occur at the end of the project when all construction costs are known.

5.5 Combining Funds from Multiple Projects
In general, public art will be installed within or adjacent to the building or place for which the appropriation, bonds, or gift was received, if appropriate. Public art funds received from two or more capital projects may be combined or pooled to acquire or create a single artwork of higher quality or of greater City impact than could be achieved through two or more individual artworks. The Commission may recommend the combination of funds to the City Manager for approval.

Combining funds allows looking at the needs of the City as a whole and using the art monies only for those projects that may have the greatest impact on the community or offer the best opportunities for artist involvement. When appropriate, pooling allows the Commission to ensure that art projects are adequately funded. The Commission will recommend which City construction projects will include an art project to the City Manager.

5.6 Appropriate Use of Public Art Program Funds
Public Art Program funds may be used for the following purposes, whether the artwork is directly related to a specific City project:
a. Selection, acquisition, and installation of artworks: Includes both temporary and permanent art installations, provided they meet the eligibility criteria outlined in Section 8.0: Selection Procedures.

20 7.0 Site Selection
When identifying sites for artwork, it is important to consider both the specific project and broader public space needs. The process ensures that the artwork enhances its location, whether it is integrated into a City project or placed in a more general, public area. The Commission, the Artist Selection Ad Hoc or Panel (if formed), the selected artist(s), and City staff will collaborate to identify potential sites for the artwork. The Commission will utilize identified sites and relevant guidelines to assess the suitability of available public spaces on a case-by-case basis.

7.1 Process for Identifying Artwork Sites
a. Integration with Specific Projects: When Public Art Program funds are associated with a particular construction project, efforts should be made to integrate or place the artwork in or near the project area. For these installations, the site selection and planning will occur during the schematic phase of the project, ensuring that the artwork is thoughtfully incorporated into the overall design and functionality of the space.
b. Broader Public Space Opportunities: Public Art Program funds are not limited to sites directly associated with a specific construction project. Artwork can be placed in various public spaces throughout the City, based on availability and suitability. The goal is to select locations that will maximize the artwork's impact and accessibility to the community.
c. Site Selection:
● Artist Selection Ad Hoc, Panel or Commission: Leads the process of identifying possible sites for the artwork. If the artist(s) have been selected, they will provide input on site selection.
● City Staff: Provides technical support and input regarding site feasibility, safety, and City requirements.
d. Evaluation Criteria: The following criteria will be used to evaluate the site or alternative sites for the artwork:
a. Visibility and public access to the site.
b. Interior and exterior traffic patterns to and around the site. c. Existing architectural and natural features adjacent to the site. d. Existing works of art or design elements within the site’s vicinity. e. Potential impact of the artwork on the surrounding environment, including existing infrastructure.
f. Potential impact of the artwork on other City departments, residents, and businesses.
g. Future development potential of the site.
h. Public safety concerns.
i. Maintenance requirements.

21 e. Consultation with City Departments: The Commission and City staff will consult with affected City departments to gather input on site suitability, development requirements, and any potential conflicts.
f. Recommendation for City Council Approval: After evaluating potential sites and consulting with relevant stakeholders, the Commission will include the recommended site as part of their broader recommendation for a specific public art installation. This comprehensive recommendation, which encompasses both the site and the proposed artwork, will then be submitted to the City Council for final approval.

22 8.0 Selection Procedures
The Commission selects artists and artworks for public art projects—both temporary and permanent—through methods such as open competition, direct selection, limited competition/invitational approaches, or sponsored proposals. While some artworks may be integrated into specific construction projects, not all installations will be associated with such projects.

The selection process follows the outlined steps and incorporates specific criteria based on the type of installation and its context. For installations tied to construction projects, site selection and artwork integration occur during the schematic design phase. For other installations, the same evaluation and selection process applies, ensuring that all projects are reviewed for feasibility and artistic merit.

Temporary installations, including those proposed and sponsored by external entities, are subject to the same criteria. The recommendation and approval process will follow the Public Art Program's procedural guidelines, if applicable, to determine when a project proceeds to the Commission and then to the City Council. All selected artist(s) and installation plans are recommended by the Commission to the City Council for consideration and approval.

8.1Methods of Selecting Artists or Artwork
a. Open Competition
i. Any professional artist is eligible to participate, subject to limitations established by the Commission.
ii. A Request for Qualifications (RFQ) or Request for Proposals (RFP) is developed and widely distributed through local media, arts media, and direct mailings to artists and arts organizations. The RFQ or RFP shall include:
● A description of the project including its goals and the project parameters, including the characteristics of the site, potential approaches to the project and any physical or legal restrictions that may apply.
● The anticipated scope of work for the artist.
● Application procedures, including requested materials, eligibility factors, and timelines.
● Selection procedures.
● Criteria for the selection of artist(s) and artwork(s). ● The project budget.
b. Direct Selection: For some projects, the Commission may:
i. Select one or more artists through direct invitation or solicitation of names from artists, arts organizations, galleries, or other sources. ii. Develop a shortlist of qualified artists for review by a selection ad hoc or panel, which may recommend artists or completed artworks directly to the Commission.

Agenda Item #9.2:

PUBLIC ART POLICY AND PROCEDURES

23 iii. Any selection for professional services must comply with the City’s Municipal Code and Procurement Policy.
c. Invitational: Artists are invited by the Commission to submit proposals or completed artworks. Applicants may be pre-screened and evaluated based on the RFQ or RFP.

The Artist Selection Ad Hoc or Panel (if formed) reviews the qualified candidates. d. Proposals for Art Installations: An entity (such as a business, organization, or community group) may propose an art installation that they sponsor. These installations may be fully or partially funded through the Public Art Fund or other sources identified by the Commission. Funding requests should be submitted as part of the proposal process.
i. Proposal Submission: The sponsoring entity submits a proposal detailing the artwork or exhibit, site suggestions, and sponsorship information. ii. Review and Coordination: The Commission reviews the proposal and coordinates with City staff to ensure the site or sites are suitable and meets City requirements.
iii. Approval Process: If recommended by the Commission, the proposal is presented to the City Council for approval. If approved, the installation will proceed according to the agreed terms.

After an artist is selected through one of the methods outlined in this section, the feasibility of potential artwork sites will be evaluated. The process of identifying and evaluating potential sites will follow the steps and criteria outlined in Section 7.0: Identifying Sites for Artwork. Collaboration between the Artist Selection Ad Hoc or Panel, the selected artist(s), and City staff will ensure the selection of an appropriate site.

8.2 Artist Selection Criteria
Artists will be evaluated by the Commission, Artist Selection Ad Hoc Committee, and/or Panel based on the following criteria:
a. Artistic quality, including craftsmanship, originality, and material integrity. b. Appropriateness of the artwork to the community, including scale, form, content, and design.
c. Relationship of the artwork to the social and cultural identity of the community. d. Artist’s proposed budget and ability to complete the project on time and within the budget.
e. Proposed materials and their suitability regarding structural integrity, protection against theft and vandalism, public safety, weathering, and long-term maintenance needs.
f. Proposed method of installation and evaluation of safety and structural factors. g. Durability of materials and projected maintenance cost. h. Additional factors, such as long-term maintenance and material durability, will be emphasized for permanent installations. Temporary works will be evaluated with a focus on the temporary nature of materials, ease of installation and removal, and site restoration.

j. Exclusion of works by project architects, design team members, or artists related to the Commission, Artist Selection Ad Hoc Committee or Panel, or City employees. k. Artists may not receive more than two commissions from the City of Sonoma in any five-year period or more than one commission in consecutive years. These restrictions apply to individual artists, teams, and artists credited with commissioned projects.
l. Artists may be selected nationally or internationally, though preference may be given to Sonoma County-based artists. The Commission encourages diversity in style, scale, media and the exchange of creative skills.

8.3 Competitive Selection

8.3.1 Artist Selection Ad Hoc Committee
The Commission may choose to create an Artist Selection Ad Hoc Committee (Ad Hoc) to assist in the evaluation and recommendation of artists for specific public art projects.

This Ad Hoc will be formed based on a staff recommendation when a project warrants additional, focused review. Alternatively, the City Manager may choose to establish a separate Artist Selection Panel (Panel) if a project requires a more comprehensive selection process.

Ad Hoc Committee Membership and Structure
• The Ad Hoc must be composed of fewer than a quorum of the Commission to maintain flexibility and ensure adherence to non-Brown Act requirements. • Assigned City staff, consultants and art professionals may serve as advisors, providing insight into site conditions, historical context, and technical requirements that may impact the artwork.

Limitations and Scope
• The Ad Hoc operates in an advisory capacity only, with the responsibility of providing recommendations to the full Commission. It does not have final decision-making authority.
• The Ad Hoc’s purpose is limited to the specific project for which it is formed, and it will be disbanded once its recommendations are submitted to the Commission.

8.3.2 Artist Selection and Design Review Process
The selection process is as follows:
a. Method Selection: The Commission, Ad Hoc, or Panel selects one of the methods of selecting artists or artwork listed in Section 8.1: Methods of Selecting Artists or Artwork.

Each Commissioner, Ad Hoc Member, or Panelist has one vote; no Commissioner, Ad Hoc Member, or Panelist has the right to veto. The Commission, Ad Hoc, or Panel may also opt to make no selection.
d. Commission Review: If an Ad Hoc or Panel has been formed, their recommendation is submitted to the Commission for consideration. e. Direct Recommendation to City Council: If the Commission acts as the selection panel, their recommendation goes directly to the City Council for consideration.
f. City Council Approval: If approved by the City Council, the Commission directs the artist to commence the project.
g. No Selection Made: If no selection is recommended, the Commission decides whether to:
