City of Corona – 2024 Electric Utility Greenfield Rate Study 20 4 COST OF SERVICE ANALYSIS
The objective of the COSA is to analyze costs and equitably assign those costs to customers commensurate with the cost of serving those customers. The founding principal of cost allocation is the concept of cost-causation. Cost-causation evaluates which customer or group of customers causes the utility to incur certain costs by linking system facility investments and operating costs to serve certain facilities to the services used by different customers. This section of the report will discuss the general approach used to apportion the utility’s cost of service and provide a summary of the results.

4.1 COSA Definition and General Principles
A COSA study allocates the costs of providing utility service to the various customer classes served by the utility based upon the cost-causal relationship associated with specific expense items. This approach is taken to develop a fair and equitable designation of costs to each customer class, where customers pay for the costs that they incur. Because the majority of costs are not incurred by any one type of customer, the COSA becomes an exercise in spreading joint and common costs among the various classes using factors appropriate to each type of expense. The COSA is the second step in a traditional three-step process for developing service rates. The first step is the development of the test period revenue requirement for the utility, which is the starting input for the COSA. The COSA then spreads the revenue requirement across the various customer classes, creating per unit costs by class. In the third step, rates are designed for each customer class, with per unit costs being one consideration in setting the appropriate rate levels.

A COSA study can be performed using embedded costs or marginal costs. Embedded costs generally reflect the actual costs incurred by the utility and closely track the costs kept in its accounting records.

Marginal costs reflect the cost associated with adding a new customer and are based on costs of facilities and services, if incurred at the present time. While marginal costs can be valuable for designing rates in certain instances, marginal costs are generally higher than embedded costs. Therefore, the use of a marginal COSA study usually requires that all costs be scaled back to a level equal to the embedded cost revenue requirement established using actual or projected costs from an “accounting” perspective.

This study uses an embedded COSA as its standard methodology. Therefore, the City’s electric utility embedded cost revenue requirement and existing rate base investment are used in developing the COSA results. Both the utility’s revenue requirement (ongoing expenses) and the value of its fixed assets (plant) are spread across customer classes. The allocation of the fixed assets is then used to spread ongoing O&M costs according to how each class utilizes the utility investments.

City of Corona – 2024 Electric Utility Greenfield Rate Study 21 There are three basic steps to follow in developing a COSA, or spreading expenses and fixed asset values across customers, namely:
 Functionalization
 Classification
 Allocation
Functionalization separates costs into major categories that reflect the utility’s plant investment and different services provided to customers. Plant investment includes infrastructure such as control panels, switches, transformers, and wires and it includes other necessary investments to run the utility business such as software or property. The primary functional categories are production, transmission, distribution and general.

Classification determines the portion of the cost that is related to specific cost-causal factors, such as those that are demand-related, energy-related or customer-related. Production costs are related to supplying and transporting power to customers on the system. Transmission costs are related to the bulk transfer of power throughout the system, which is designed to meet the peak demand requirement. The distribution system is designed to extend service to all customers attached to the system and to meet the peak load capacity requirement of each customer. Additionally, costs can be classified based on system revenues or directly assigned to a customer or group of customers.

Allocation of costs to specific customer classes is based on the customer’s contribution to the specific classifier selected. For instance, demand-related costs are allocated to a customer group using that customer group’s contribution to the particular measurement of system demand, whether coincident peak, non-coincident peak or some variation determined to be appropriate for the particular cost item. An analysis of customer requirement, loads and usage characteristics is completed to develop allocation factors reflecting each of the classifiers employed within the COSA. The analysis may include an evaluation of the system design and operations, its accounting and physical asset records, customer load data and special studies.

4.2 General Ratemaking Principles
While this section does not address the design of rates, it is important to note that the COSA results will be one of the considerations when the process of designing rates for various customer classes begins.

The basic goals of rate design include:
 The utility has an ability to collect the appropriate revenue requirement  Utility revenues and customer rates are stable and predictable  Proper price signals are sent to create efficiency of resources

City of Corona – 2024 Electric Utility Greenfield Rate Study 22  Rates are fair and equitable among customers and avoid undue discrimination  Rates are simple, easy to understand and feasible for the utility to implement The COSA is generally used to assist in meeting the second and fourth goals of rate design. Price signals are best if they reflect the specific costs incurred. Rates are generally considered fair and equitable if customers are deemed to pay their share of the costs incurred by the utility. Additionally, the first goal is met as long as the COSA is based on the appropriate revenue requirement, and the use of a consistent COSA methodology contributes towards the second goal. Rates are more stable through time if the COSA methodology is not significantly changed every time a rate application is made.

4.3 Functionalization of Costs
The first step in the COSA process following finalization of the revenue requirement is to functionalize the revenue requirement and the rate base (plant). Functionalization is the separation of cost data into the functional activities performed in the operation of a utility system (i.e., power supply, transmission, distribution and customer service). Functionalization was accomplished using the City’s system of accounts, which largely segregates costs in this manner.

In addition to the functionalized costs, certain joint costs are spread to each functional category based on the relationship of the joint cost to the business function. These joint costs include such items as administrative and general costs.

Standard Functionalization
Plant investment costs or rate base are generally functionalized into production, transmission, distribution and general cost categories. The functionalization of rate base typically is very straightforward as costs for the different functions are readily identifiable and rate base accounts are maintained by functional categories.

Expense accounts are also typically kept according to these basic functional categories, with expense items associated with certain types of plant being treated in the same manner as the corresponding plant account.

The two areas where there generally are differences in functionalization among utilities are in the treatment of general plant and administrative and general (A&G) expenses. Typically, general plant is considered a separate functional category. Some utilities, when their internal accounting systems can support such an assignment process, will record general plant investment by loading the costs into the other functional categories, much like an overhead assignment or a form of activity-based accounting.

City of Corona – 2024 Electric Utility Greenfield Rate Study 23 On the expense side, A&G costs can be treated in much the same way. Generally, they are treated as a separate expense category that can be spread to functions based upon all other O&M expenses.

However, they can also be spread to functions on the basis of total net plant, labor ratios or, in some cases, directly assigned as part of the activity-based accounting approach.

Table 22 displays the functionalization of the FY 2025 revenue requirement. Because the City does not own any transmission assets, only product (power supply) and distribution are shown.

Table 23 summarizes the functionalization of the City’s fixed assets related to the electric utility. All fixed assets are functionalized as distribution.

Distribution 360-373 $15.0 100% Distribution
General Plant 389-399 $0.2 100% Distribution
Total Gross Plant $15.2

4.4 Classification of Costs
The second step in performing a cost of service analysis is to classify the functionalized expenses to traditional cost causation categories. These cost causation categories can be directly related to specific consumption behavior or system configuration measurements such as coincident peak (CP) or noncoincident peak (NCP) demand, energy or number of customers. Each classification category will have a specific allocator that, when applied, will distribute those costs among the appropriate customer classes during the allocation phase of the analysis.

City of Corona – 2024 Electric Utility Greenfield Rate Study 24 Functionalized power purchases, generation and transmission system costs are classified as demandrelated and/or energy-related and in some instances directly assigned, while distribution costs are classified as demand- or customer-related, or directly assigned to specific customer classes of service.

Standard Classification
The three most general classification categories are demand-related, energy/commodity-related and customer-related. Within these three categories there are multiple ways of defining each option as well as varying ways to split costs between two or more classifiers. For example, demand- and energy-related costs can be separated by seasonal distinctions as well as to reflect peak/off peak consumption periods.

Customer-related costs could be separated by demand and customer categories, while customer categories can distinguish between actual customer and weighted customer characteristics. Other classifiers sometimes used in the process include revenue-related and direct assignment. In addition, there are many instances where costs are not specifically classified to a particular category but rather in the same manner as an individual cost account or subtotal of specific cost accounts. For example, some of the overhead costs, like Administrative & General, are classified based on how all other O&M costs are classified which includes a classification to energy, demand, or customer.

Generally, power production and purchased power costs are classified by a combination of demand and energy. Transmission costs are generally classified as peak demand, while distribution costs are generally split between demand and customer. The City’s electric utility purchases transmission service from the California Independent System Operator (CAISO). CAISO provides the load balancing services for much of the State. Because CAISO bills transmission based on energy, transmission costs for the City are classified as energy.

There are two methodologies that can be used to classify distribution costs: 100% demand and minimum system. The 100% demand methodology assumes that the distribution system is built to meet the noncoincident peak. Therefore, distribution costs are classified as 100% demand-related. Specific distribution costs are sometimes split between demand and customer according to a minimum system approach.

This approach reflects the philosophy that the system is in place in part because there are customers to serve throughout the service territory expanse, and that a minimally sized distribution system is needed to serve these customers even if they only use 1 kWh of energy per year. The concept follows that any costs associated with a system larger than this minimal size are due to the fact that customers “demand” a delivery quantity greater than the minimum unit of electricity and that therefore, those costs should be treated as demand-related. Because the residential class tends to have a higher share of the number of customers as compared to the share of non-coincident peak, the minimum system methodology tends to

City of Corona – 2024 Electric Utility Greenfield Rate Study 25 allocate more costs to the residential customer class and customer charges tend to be higher than with the 100% demand methodology.

The process of cost classification is the area within the COSA that can create considerable cost variability between customer classes due to differences in system configurations, demand measurements and assignment philosophy. The complexity of the entire COSA process is further compounded since, in some cases, the classification category is clear, but the specific allocator is not. For example, a particular cost item may clearly be peak demand-related but that demand can be measured as either a single coincident peak for the year, a 2 coincident peak (CP) approach to reflect seasonal considerations, the sum of 12 monthly coincident peaks or through some other approach such as “Average & Excess.” City of Corona Classification Method
The following describes the specific classifiers used in the City’s electric COSA within each of the four functions.

Power Supply
Classifying power supply costs to demand and energy (commodity) components requires the evaluation of a number of complex, interrelated factors. Consideration must be given to what or who caused the power supply purchase to be made, and to the uses to which it will be put (i.e., meeting demand and energy requirement). Within this study, power supply costs are classified to demand and energy based on the City’s power cost forecast for the test period. The specific classifiers used for the power supply function include Energy and Demand.

Energy-related costs are those that vary with the total amount of electricity consumed by a customer.

Electricity usage measured in kWh is used in this portion of the analysis as well. Energy costs are the costs of consumption over a specified period of time, such as a month or year.

Demand-related costs are those that vary with the maximum demand or the maximum rates of power supply to customer classes. Customer and system demand for this analysis were measured in kW.

Demand costs are generally related to the size of facilities needed to meet a customer’s maximum demand at any point in time.

All of the City’s power supply costs are purchases related to energy including most transmission purchases. Transmission purchases through CAISO or Southern California Edison (SCE) are included in this section of the revenue requirement. CAISO wheeling and the various facility charges are classified as demand-related since those costs are incurred by the utility based on demand readings.

City of Corona – 2024 Electric Utility Greenfield Rate Study 26 Transmission (Utility-Owned)
The transmission function includes the utility’s own transmission assets associated with providing power to the City’s distribution system. Transmission services that the City purchases in order to facilitate the delivery of wholesale power purchases to the City’s service area are included in power supply costs. The costs associated with the local utility’s transmission service include only those costs for operating and maintaining the transmission lines, poles, towers, substations, etc. used to deliver power to the distribution network. The cost of providing transmission service to a customer is considered to be directly proportional to the demand that customer imposes on the system. The City does not own transmission equipment; therefore, these line items are not included in the analysis.

Distribution
Distribution services include all services required to get energy supply from the point of interconnection between the transmission system and the utility’s service area to the end user of the power. Classifying distribution costs requires a special analysis of the nature of the costs. Because the City has collected billed demand data, the distribution system costs are classified as demand-related using the 100% demand approach described earlier.

Customer
Customer-related services include all services related to the presence of customers on the system, not to customer usage. These services include meter reading, billing, collections, advertising, etc. Customerrelated costs vary with the number and type of customers. They do not vary with system supply levels.

These costs are sometimes referred to as “readiness to serve” or “availability” charges. Customer costs are incurred by the utility to have electricity supply readily available for a customer whether it is utilized or not.

There are two types of customer-related cost classification categories—actual and weighted. Actual customer costs vary proportionally with the addition or deletion of a customer, regardless of the size or usage characteristics of the customer. An example of an actual customer-related cost is billing services needed to develop monthly customer bills. In contrast, a weighted customer cost reflects a disproportionate cost attributable to the addition or deletion of a customer. An example of weighted customer costs is meter-reading expenses. In some cases, it takes less time and effort to read a residential energy meter than it does to serve a large commercial customer that also has a demand meter. This type of difference is accounted for in the weighted customer allocation factors.

Direct Assignment
Some costs can be directly assigned to certain customer classes without being classified as demand-, energy-, or customer-related. These are generally costs associated with specific services, such as dedicated capital facilities, or with specific customer classes, such as lighting customers. Direct

City of Corona – 2024 Electric Utility Greenfield Rate Study 27 assignments include costs incurred to maintain and serve city-owned streetlights. The City of Corona does not have any expenses that are directly assignable.

Total $5,621,655 $0 $555,841

4.5 Allocation of Costs
The third step in performing a cost of service analysis is the allocation of the utility’s total functionalized and classified revenue requirement to the customer classes of service. This is performed through the application of an appropriate allocation methodology.

City of Corona – 2024 Electric Utility Greenfield Rate Study 28 City of Corona Allocation Methodology
The following are the specific allocation methods used in the City’s electric COSA.  Demand Allocation Factors. For purposes of this study, two types of demand allocation factors were developed.
o Non-coincident peak demand allocation factor (NCP). First, a non-coincident peak demand allocation factor was developed for each customer class. Expenses classified and allocated by the non-coincident peak demand allocation factor included those predicated on maximum demands such as distribution substations, and a portion of poles and lines, mains, meters and services. The NCP demand method allocates costs to each class of service based upon their highest individual non-coincident peak demand regardless of the time of occurrence. The NCP allocation factor is used to allocate distribution.
o Sum of monthly coincident peak (12 CP). A contribution to monthly system coincident peaks was derived from the non-coincident peak by use of a coincidence factor. This coincident peak demand allocation method is referred to as the sum of the monthly coincident peak (12 CP) method. The 12 CP method allocates demand costs on the basis of demand value at the time of the system peak demand in each month by each class. As discussed previously, the 12 CP method is used for power supply costs and transmission costs.
 Energy Allocation Factors. Energy costs vary directly with consumption. Accordingly, energy allocation factors were based upon electricity sales for each class. Energy allocation factors were used to allocate power supply costs, green-energy related costs and revenues and surplus sales revenue.
 Customer Allocation Factors. Two basic types of customer costs were identified – actual and weighted. The allocation factor for actual customers was derived from the actual number of customers served in each class of service. Two weighted customer allocation factors were also developed. The first weighted customer allocation factor considered the relative differences among the various customer classes of meter costs. The second weighted customer allocation factor considered the cost of customer accounting and meter reading by each rate class.

Customer allocation factors were used to allocate some distribution costs such as meters and meter installations, and costs associated with customer service, accounts and sales.  Rate Base Allocation. The value of the City’s electric system was estimated as of FY 2023 and is functionalized, classified and then allocated to customer classes. The resulting functionalized,

City of Corona – 2024 Electric Utility Greenfield Rate Study 29 classified and allocated rate base is then used to develop rate base allocation factors. These allocation factors (i.e., general plant, net plant, distribution rate base, etc.) are then used to allocate revenue requirement expenses. For example, maintenance of station equipment can be allocated using station equipment rate base, or property taxes might be allocated using net plant.  Other Cost Allocation. Other costs are allocated based on specific rate base items, O&M function totals, revenues, labor ratios and other allocation factors. These other allocation factors were used to allocate administrative and general expense items, as well as some other revenues such as dividend income or non-operating rental income.
 Administrative and General (A&G). All costs that are related to general overhead are classified to this area. Costs are allocated to customers based on their percentage of all other O&M expenses without power supply.
 Miscellaneous/Other Revenues. Miscellaneous/other revenues are generally allocated to customers based on allocation of all other O&M expenses.

The rate base allocation is shown in Table 26. The table summarizes how each rate class uses the distribution system based on their relative share of demand and size of services and meters.

Table 27 summarizes the load data used for customer class allocations.

Table 28 shows the allocated revenue requirement. Lastly, Table 29 summarizes the COSA results and indicated rate adjustments. These rate adjustments are the basis for the recommended rebalancing proposal for the rate design provided in the next section.

City of Corona – 2024 Electric Utility Greenfield Rate Study 32 5 ELECTRIC RATE DESIGN
EES proposes the following adjustments to the Greenfield rate structures:
 Adjusting rates annually by the recommended revenue adjustments of 4.0 percent per year.  Rebalance customer class rate levels to recover the rate class cost of service. These adjustments may result in rate adjustments that differ from the total 4.0 percent adjustment.  Increasing the fixed proportion of rate collection to align with COSA results.  Removing the highest cost tier to simplify the rate structure.  Separate the PBC from base rates to improve transparency.  Remove seasonal difference from energy rates.
 Implement a Specific rate for commercial electric vehicle charging stations.  Recover power supply-related demand costs throughout the year rather than just summer peak periods.
 Rebalance customer class revenue collection based on COSA results.

The rebalancing proposal is provided in Table 30 below. The proposed adjustment to the pumping and agriculture class is recommended to be implemented over an 18-month period. This longer period will allow existing customers to adjust their usage patterns to avoid large bill impacts.

The electric rates have up to four components: 1) a fixed monthly service charge 2) volumetric rates, (3) demand charges, (4) Power Factor Adjustment, and (5) Public Benefits Charge. Customers must pay the fixed charge regardless of energy use or demand.

1. Fixed monthly service charge: The rates are established based on the size of the meter at the property receiving electric service and are calculated to recover a portion of the City’s fixed costs, such as meter reading and customer service.

City of Corona – 2024 Electric Utility Greenfield Rate Study 33

2. Variable rates: The rates are calculated based on the cost of wholesale electricity and transmission. The remaining fixed costs that are not recovered via fixed charges (fixed or demand charges) such as the cost of maintaining the electric distribution system, are also recovered from variable charges. The rates are billed per kWh.

3. Demand Charge For demand-metered customers, demand charges recover the cost of demandrelated power supply expenses and the cost of maintaining the electric distribution system. These charges are billed each month based on maximum kW.

4. Power Factor Adjustment: The power factor adjustment recovers the cost of inefficient use of power on the customer side of the meter. The power factor is the ratio of real power to apparent power. The power factor adjustment is billed per kVa.

5. Public Benefits Charge: In 1996, the State of California required all publicly owned electric utilities to establish a charge for programs that would benefit the public such as low-income assistance, energy efficiency, and renewable resources. The Public Benefits Charge (PBC) is equal to 2.85% of the utility’s annual revenue requirement.

Combining the rates and billing determinants for each customer results in monthly bills and annual revenue consistent with the cost of providing electric service. Each subsection below provides the unit COSA results, current rates, and proposed rates. The proposed rates are developed consistent with COSA unit costs to improve interclass equity.

5.1 Recommended Residential Rates
The proposed residential rates, as shown in Table 31, increase the fixed charge based on the COSA results (unit costs in column 1). The fixed charge is recommended for both single family and multifamily accounts as the cost of meter reading and billing is similar for both types of dwellings. The energy rate is reduced to account for the increase in fixed charge and the separation of the PBC (currently $0.00378/kWh based on 2.85% of the total revenue requirement). Additionally, the energy rate structure is simplified from 4 tiers down to 3 tiers. Most usage (64.2%) is in the Tier 1 baseline followed by 11.2% in Tier 2 and 24.6% in the new Tier 3. Maintaining the tiers encourages efficient use of electricity while not penalizing customers who adopt electric vehicles. Once the planned metering infrastructure is in place, it is recommended to re-evaluate the rate design to consider time-of-use rates which best represent the marginal cost of power supply for all customers.

5.2 Recommended Small Commercial (GS-1) Rates
The recommended small commercial rates increase the fixed charge based on the COSA results (unit costs in column 1) and shown in Table 32. The energy rate is reduced to account for the increase in fixed charge and the separation of the PBC (currently $0.00378/kWh). Additionally, the energy rate structure is simplified so that the rate is the same year-round instead of the differential between summer and winter.

When reviewing seasonal power costs, we found that there was no significant difference in costs between summer and winter. The COSA unit costs separate demand and energy costs. Because this class is not demand-metered, the demand costs are recovered through the variable energy rate proposed.

5.3 Recommended Medium Commercial (GS-2) Rates
The recommended Medium Commercial rates decrease the fixed charge based on the COSA results (unit costs in column 1) and shown in Table 34. The energy rate is reduced to account for the separation of the PBC (currently $0.00378/kWh) and increase in demand rates. Additionally, the energy rate structure is simplified so that the rate is the same year-round instead of the differential between summer and winter. When reviewing seasonal power costs, we found that there was no significant difference in costs between summer and winter energy costs. The demand rate is adjusted so that power supply demand-related costs are collected year-round consistent with how the utility is billed for power supply.

The facilities charge is increased to recover the fixed costs of the distribution. The power supply demand rate recovers the power supply related expenses incurred throughout the year.

5.4 Recommended Large Commercial (TOU-GS-3) Rates
The recommended Large Commercial rates decrease the fixed charge based on the COSA results (unit costs in column 1), and shown in Table 36. The energy rate is reduced to account for the separation of the PBC (currently $0.00378/kWh) and increase in demand rates. Additionally, the energy rate structure is simplified so that the rate is the same year-round instead of the differential between summer and winter.

When reviewing seasonal power costs, we found that there was no significant difference in costs between summer and winter energy costs. The demand rate is adjusted so that power supply demand-related costs are collected year-round consistent with how the utility is billed for power supply. The facilities charge is increased to recover the fixed costs of the distribution. The power supply demand rate recovers the power supply related expenses incurred throughout the year. The time of use energy rates reflect the actual power costs weighted according to the marginal cost of power supply during the respective billing periods.

5.5 Recommended Industrial (TOU-8) Rates
The recommended Industrial rates decrease the fixed charge based on the COSA results (unit costs in column 1), as shown in Tables 38 and 39. The energy rate is reduced to account for the separation of the PBC (currently $0.00378/kWh) and increase in demand rates. The demand rate is adjusted so that power supply demand-related costs are collected year-round consistent with how the utility is billed for power supply. The facilities charge is increased to recover the fixed costs of the distribution. The power supply demand rate recovers the power supply related expenses incurred throughout the year. The time of use energy rates reflect the actual power costs weighted according to the marginal cost of power supply during the respective billing periods. This marginal cost pricing methodology is considered best practice in time of use rate-making for electric utilities.

5.6 Recommended Pumping and Agriculture (TOU-PA-2) Rates The recommended pumping and agriculture rates decrease the fixed charge based on the COSA results (unit costs in column 1). The energy rate is reduced to account for the separation of the PBC (currently $0.00378/kWh) and increase in demand rates. The demand rate is adjusted so that power supply demand-related costs are collected year-round consistent with how the utility is billed for power supply.

The facilities charge is increased to recover the fixed costs of the distribution. The power supply demand rate recovers the power supply related expenses incurred throughout the year. The time of use energy rates reflect the actual power costs weighted according to the marginal cost of power supply during the respective billing periods. Table 40 below shows the rate adjustment planned over the 18-month phasein period. The increase in the PBC in January of 2026 is due to the increase in revenue requirement in that year. Similarly, the fixed charge in January 2026 aligns with the fixed charge calculated by the COSA for FY 2026.

5.8 Recommended Commercial Electric Vehicle Charging Rates Current commercial EV charging stations are being served at the TOU-8 rate schedule, as shown in Table 42. The TOU-8 rate schedule more appropriately applies to services with high load factors, however, EV charging stations typically have very low load factors, often below 20%. These low load factors are associated with higher costs to serve. Therefore, it is recommended that a special EV charging rate be implemented so that the cost of service for these customers is not being shared with other rate classes. The recommended rate below takes the fixed charge and facilities charge from the TOU-8 rate schedule. Power-supply related demand costs are recovered through the recommended energy rates.

The on-peak and off-peak period energy rates provide incentives to customers to use the charging stations during off-peak periods.

46 City of Corona – 2024 Electric Utility Greenfield Rate Study

Important Information About Your Water Rates
The City of Corona City Council will conduct a public hearing to consider changes to the water and sewer rate structures and rates. The proposed changes are based on an independent cost-ofservice study that was completed and received by City Council in October 2024.

All property owners and customers of record whose parcels receive water, reclaimed water, and/or sewer services provided by the City of Corona are being issued this notice of public hearing. The proposed rate adjustments will be applicable to all parcels that receive water, reclaimed water, or sewer services from the City of Corona. The hearing is open to the public.

The property owners upon which the rates and charges are proposed and for any tenants directly responsible for the payment of water, reclaimed water and sewer service fees and charges may submit a written protest to the proposed rate changes provided that only one protest will be counted per parcel. See “How Can I Participate?” to learn more.

Additional information about the proposed changes is available in this document and online at CoronaCA.gov/rates
Wednesday, November 20, 2024
Time: 6:30 p.m.

Location: Corona City Hall, 400 South Vicentia Ave
Corona, California 92882
Notice of Public Hearing

PROPOSED CHANGES TO WATER & SEWER RATE STRUCTURES
Este documento es importante para todos los residentes de la Ciudad de Corona.

Para recibir este aviso en español por favor, póngase en contacto con la ciudad llamando al (951) 736-2321.
400 S. Vicentia Ave. Corona, CA 92882 | P: (951) 736-2321 | CoronaCA.gov Page 508 of 633 Corona: At A Glance
The City of Corona reliably delivers water, reclaimed water, and sewer services to residents and businesses throughout our 39.2 square mile service area. We serve a population of more than 160,000 residents.

WATER SERVICE
Our water services ensure local families, business and the community have access to safe, high-quality water, high-quality water. In 2023, Corona residents and businesses used approximately 9.1 billion gallons of drinking water. Corona’s water supply comes from different sources: groundwater wells owned and operated by the City of Corona provide 45.8 percent, 49.7 percent comes through Lake Mathews from the Colorado River, and 4.5 percent comes from the State Water Project’s California Aqueduct.

SEWER SERVICE AND RECLAIMED SERVICE
The City of Corona’s sewer system serves approximately
144,000 customers and treats 13.5 million gallons per day on average. We have a long history of recycled water facilities — the City of Corona’s first water reclamation facility was built in 1968, and the clean water was returned to the environment.

Our large-scale water reclamation system saves precious drinking water for homes and businesses by generating
reclaimed water for golf courses, local parks and school grounds. It serves approximately 387 connections.

Why Have I Received
This Notice?
You have received this notice because the City of Corona is considering rate adjustments and structural changes affecting your water, reclaimed water and sewer service charges. The City is committed to transparency:
this document and the public hearing will further explain the research, reasoning, and analysis behind these proposed rate adjustments.

Why Are Rate Changes Being Considered?
Rate adjustments are being considered to support resilient infrastructure, to avoid unplanned service interruptions, and ensure the City can continue to provide first-rate utilities to its families and businesses. The proposed rates fund operations and necessary capital projects to advance community sustainability. The City maintains revenue stability through rate changes to protect financial sufficiency — another vital part of reliable, continued service.

The City of Corona is considering water rate adjustments to address regulatory changes necessary for the proactive treatment of chemicals such as perand polyfluoroalkyl substances (PFAS) and 1,2,3-trichloropropane (TCP).

Metropolitan Water District of Southern California’s imported water rate hikes have also impacted our wholesale water provider, Western Municipal Water District, and those increases have trickled down to our rates here at the City of Corona. 3 Page 510 of 633
How Will This Impact My Bill?
As a government agency, the City can only charge what it costs to provide a utility service. This means the customer will never pay more than their fair share of the service cost.

The proposed water, reclaimed water, and sewer rate adjustments are based on an independent study completed in 2024 that evaluates the cost of providing utility service. This includes operations and maintenance, debt service, and capital expenditures. If rate adjustments are approved, most residential customers would see an increase in their water bill and a slight decrease in sewer in the next year.

The new proposed water rate structure also refines billing tiers, making customer utility bills simpler to understand and more accessible.

The sewer rate change increases customer equity by reducing residential rates. Residential customers will see a 14-cent per month decrease in 2025.

may affect your household or
business, use our bill estimator

New State Mandates Require Reduction in Indoor
Water Use in 2025
The proposed water rate change reflects upcoming state water reduction mandates, enabling the community to contribute to conservation.

Starting January 3, 2025, the standard for indoor residential water use shall be 47 gallons per capita daily. This is part of the state’s effort to advance long-term urban water use efficiency.

Understanding the Proposed Water Rate Structure
Your water bill includes a monthly fixed ready-to-serve charge. This is for each water service connection and is paid by all users connected to the City’s water system, whether or not any water is actually used.

Your water bill also includes variable charges based on water usage. The variable water rate is established by the number of units of water delivered to a property and consists of four tiers that impose higher rates as the level of water use increases. A reasonable amount of water is allocated to each customer based on their particular needs; this is referred to as a “water budget.” The INDOOR WATER BUDGET
is calculated by the number of
people in the household with
an allocation of 47 gallons of
water per person per day.

The OUTDOOR WATER BUDGET is
calculated by the amount of irrigated
square footage per parcel, the average
daily plant water loss (“evapotranspiration”
(ET)), and an outdoor efficiency factor
(OEF) of 80% that reflects the water
needs of local native plants to City of
Corona’s service area.

Above that water budget,

INEFFICIENT AND EXCESSIVE
water use will cost customers
more, because it costs the City
of Corona more to secure this
additional water supply.
5 Page 512 of 633
What are Budget-Based Rates?
Think of your water budget as a series of buckets available for efficient use all month.

Indoor Use: The first
bucket is for essential
indoor water use
including drinking,
cooking and washing.

Outdoor Use: Water in
your outdoor budget is
more limited.

Use only what is needed
to tend to a Californiafriendly landscaped yard.

Inefficient Use: Variations
in your water use, such
as upticks due to filling
swimming pools or
children getting a hold
of the hose on a hot
summer day, may move
into inefficient use. You
pay more for this extra
bucket of water.

Excessive Use: When
water usage dips into
the excessive bucket,
look for leaks and more
ways to reduce water
use. You can also contact
the City for a water
audit to investigate your
increased water use.

How Your Water Budget is Calculated
INDOOR BUDGET = (number of people in household X 47 gallons per person a day X number of days in the billing period)/748 gallons OUTDOOR BUDGET (residential, reclaimed accounts and dedicated landscape meters) = (Irrigated Area x (ET/12) x 80%)/100 Indoor and Outdoor use make up the total budget. Inefficient (Tier 3) is up to 50% of the total budget. Excessive (Tier 4) amounts to 51% and higher of total budget.

The City uses 4 residents per home for single-family and 2 residents per home for multi-family units. The City has a variance program available for homes with more residents. Visit CoronaCA.gov/rates.

Understanding the Proposed
Sewer Service Rate Structure
The proposed sewer rate includes a monthly fixed charge for all customers that includes an 8 hundred cubic feet (hcf) allowance per month. Non-residential customers will be charged a variable charge for all water use beyond 8 hcf in one month (per hcf). The proposed sewer rate includes a variance process for non-residential customers.

Understanding the Proposed
Reclaimed Water Rate Structure
Your reclaimed water bill includes a fixed ready-to-serve charge. This is for each reclaimed water service connection and is paid by all users connected to the City’s reclaimed water system, whether or not any water is actually used. The Ready-to-Serve charge covers our fixed costs of providing reclaimed water. Fixed costs include debt, regulatory compliance, customer service, utility billing, personnel, and preventive maintenance. To ensure you have water when needed, the infrastructure to deliver water must be built and maintained.

Your reclaimed water bill also includes variable charges based on water usage.

The proposed variable reclaimed water rate is established by the number of units of water delivered to a property and consists of two tiers: Outdoor (Efficient) and Excess. A reasonable amount of water is allocated to each customer based on their particular needs; this is referred to as a “water budget.” Exceeding this budget will cost the customer more.

How Will Rate Adjustments Be Implemented?
As authorized by Government Code Section 53756, the proposed schedule of Monthly Rates and Water Service Charges includes fixed annual rate increases for the next five years, which will be implemented by giving a notice of adjustment to customers at least 30 days before the effective date of the adjustment. If the proposed rate schedule is approved, the City Council will, however, review the schedule at a public meeting prior to the implementation of the rate increase scheduled for January 1, 2028, to assess the accuracy of the City’s cost and revenue estimates and to reaffirm that the 2028 increase remains necessary based upon the costs expended and revenues received during the first two years of the rate increases. After such review, the City Council may direct City staff to proceed with implementing the remaining scheduled rate increases in 2028 through 2029 in an amount that does not exceed the rates set forth in the proposed schedule included as part of this notice.

How to Save Money on Your
Water Bill
The Corona Utilities Department offers ongoing programs and rebates to help residents and businesses conserve resources and money, including turf replacement, California-friendly gardening guidance and money back for water-efficient devices.

The Corona Utilities Department also provides faucet aerators, low-flow showerheads, and 5-minute shower timers to customers for free.

Here are some tips for conserving water and saving money at home:

Check for breaks or leaks in your irrigation
system. According to the USEPA, fixing
household water leaks can save residents
about 10 percent on their water bills.

Consider lowering the minutes on your
irrigation controller.

Install water-efficient rotating
sprinkler nozzles. Available rebates
include $2/nozzle for a minimum
of 15 nozzles.

Try a smart irrigation controller that
reduces your run times automatically

ELECTRICITY SERVICES IN

THE CITY OF CORONA
Our Utilities Department supplies power to approximately 3.4% of the City of Corona. Our electric utility was established in April 2001 in response to state-wide rolling blackouts and energy price instability, and we have been building upon that resilience for 1,843 bundled electricity customers ever since.

Your bill includes a monthly fixed charge that supports costs associated with regulatory compliance, billing, staff, and preventive maintenance. It also includes variable charges that support the cost of purchasing electricity, including renewable sources such as wind energy and solar. For residential customers, a monthly service charge is applied to each bill if connected to the City’s electric system. Usage charges and taxes are also charged on each bill.

Understanding the Proposed
Electricity Rate Structure
As part of the public hearing process, the City of Corona is considering changes to the electricity rate structures explained in this supplemental handout. The proposed changes are based on an independent cost of service study that was completed and received by the City Council in October 2024.

For additional information about the proposed changes, or to use our bill estimator, visit CoronaCA.gov/rates
All property owners and customers of record whose parcels receive electricity service from the City of Corona will receive this handout to explain proposed rate adjustments to electricity rates. The City is committed to transparency throughout this process.

Proposed Adjustments to Electricity Service
The City is pursuing electricity rate changes to smooth out the local electrical demand curve. The City is rebalancing electricity costs, including simplifying its rate design.

THIS ENTAILS:
‹ Reducing residential tiers from four to three
‹ Converting seasonal kWh rates to nonseasonal
‹ Monthly time-related peak demand charges put in place of seasonal demand charges Electricity rate changes also consider higher fixed charges to cover the fixed costs of providing electricity. This means that solar owners will pay their fair share of costs incurred in order to be connected to the grid.

energy use. Fixed costs include administration,
customer service, and billing.

Energy $/kWh – The energy charge recovers
variable costs associated with purchasing power.

These costs vary based on the amount of power
purchased and when it is purchased. Additionally,
for customers who are not billed demand, the
energy charge also recovers the cost of operating
and maintaining the distribution system.

Demand $/kW Power Supply (Peak) – The power
supply demand charge represents the cost of
power purchased during peak periods. Only certain
customer groups are billed demand separately
based on their capacity needs. Any demandrelated costs for customers who are not billed demand separately are included in the variable
Energy $/kWh charge.

Demand $/kW Distribution (Facilities) – The
facilities demand charge recovers the fixed costs
of the electric distribution system and the level of
investment needed to meet aggregate customer
energy demands. Only certain customer groups are
billed demand separately based on their capacity
needs. Any demand-related costs for customers who
are not billed demand separately are included in
the variable Energy $/kWh charge.

Power Factor Adjustment $/kVa The power factor
adjustment covers the additional cost related to
increased reactive power in the system created by
equipment like motors, inductors and transformers.

REQUEST FOR CITY COUNCIL ACTION
SUBJECT:

RESOLUTION ADOPTING AN UPDATED URBAN FOREST MANAGEMENT PLAN AND ORDINANCE AMENDING CHAPTER 12.22 OF THE CORONA MUNICIPAL CODE

TO CLARIFY TREE MAINTENANCE RESPONSIBILITIES
EXECUTIVE SUMMARY:

This staff report asks the City Council to approve an amendment to the Urban Forest Management Plan to include an optional tree trimming residential pay program, a tree refusal process, and protection measures for large native trees. Approval of this action will enable Community Services to offer a payment program for residents who wish to have City trees or shared responsibility trees located in the parkway adjacent to their home trimmed outside of the regular grid pruning schedule for aesthetic reasons. It will also provide residents with a refusal process for new tree planting in the resident’s parkway and allow the City to protect large native trees in both public right of way and open space. This staff report also asks the City Council to amend certain sections of Chapter 12.22 of the Corona Municipal Code (CMC) to clarify the City’s responsibilities with respect to the maintenance of city trees and shared responsibility trees.

RECOMMENDED ACTION:
a. Adopt Resolution No. 2024-084 approving the updated Urban Forest Management Program and repealing Resolution No. 2021-029.

b. Introduce, by title only, and waive full reading of consideration of Ordinance No. 3401, the first reading of an ordinance approving an amendment to Sections

12.22.030 and 12.22.050 of the Corona Municipal Code regarding the City’s responsibilities for maintenance of trees in parkways.

BACKGROUND & HISTORY:

The City of Corona’s Urban Forest Management Plan ("Management Plan") was adopted on May 19, 2021. The Management Plan outlines the guidelines and procedures for the care and protection of trees to enhance the health, safety, welfare, and quality of life for all residents, business owners, and visitors in Corona. The City of Corona ("City") recognizes that trees offer numerous benefits, including environmental, aesthetic, social, and economic advantages. Specifically, trees offer visual appeal, provide shade and cooling, conserve energy, control erosion, filter airborne pollutants, decrease noise, offer privacy, support wildlife habitats, and release oxygen.

The City of Corona has over 77,000 tree sites in open spaces and landscaped areas.

Within the framework of the City’s Tree Maintenance Program, these trees receive regular trimming following the standards as set by the International Society of Arboriculture and ANSI-A300, ensuring their health, integrity, and public safety. Regular trimming promotes the health and safety of trees, reducing the risk of falling branches or tree-related accidents. This safeguards both public and private properties and minimizes liabilities for the city. West Coast Arborists, Inc. (WCA) is the City’s contracted maintenance provider, and they trim an average of 12,000 trees annually.

Chapter 12.22 of the Corona Municipal Code sets forth the Community Urban Forest and Landscape Guidelines, which creates a framework for the planting and maintenance of city and shared responsibility trees, and provides guidance for the proper selection, planting, removal, and maintenance of the City’s community forest.

Currently, the Community Service Department maintains a five-year grid pruning schedule for all city-maintained trees, except for palm trees, which are pruned annually.

The City receives many additional tree-trimming requests each year from residents due to the proximity of many City trees and shared responsibility trees located near privately owned properties. Upon receiving such requests, staff thoroughly inspect the trees, assessing whether trimming is warranted according to current standards and criteria.

Priority is given to health and safety concerns, and requests for purely aesthetic reasons generally do not meet the City’s criteria for tree trimming.

ANALYSIS:

UPDATED URBAN FOREST MANAGEMENT PLAN
Residential Pay Program
City staff recommends updating the Management Plan to include a “Residential Pay Program” that will permit residents to pay for additional tree trimming services beyond the regularly scheduled pruning if desired for aesthetic reasons or to minimize leaf litter and fruit drop.

By proactively maintaining trees through a residential pay program, the City will optimize the allocation of resources by prioritizing tree maintenance based on the residents’ preferences. In Fiscal Year 2023, the City incurred expenditures of $400,133 for additional tree trimming requests from residents. In Fiscal Year 2024, expenditures increased to $628,526. This program is anticipated to mitigate some of these costs.

City staff will oversee the evaluation of requests under the residential pay program, assess whether trees meet the program’s criteria, and arrange the trimming schedules.

The pricing structure was established based on various factors, including the specific purpose of the requested tree trimming and the location of the tree. Based on WCA’s current pricing schedule, trees requiring trimming for clearance purposes would cost $94 per tree. Trees requested to be trimmed for aesthetic purposes and/or trees situated on aerial slopes are priced at $239 per tree, and trees on slopes are priced at $359 per tree.

Residents can request to have trees trimmed up to every six months, and all services approved within this program will be scheduled for completion within 30 days following payment. The fees charged as part of the residential pay program will correspond to the City’s then-current contracted rates for tree maintenance services.

The fees associated with the Residential Pay Program will be returned to Council for review and approval as part of the City’s minor fee update and clean-up scheduled for October 16, 2024.

Tree Refusal Process
The updated Management Plan includes a “Tree Refusal Process” that allows residents to appeal the planting of trees in residential parkways adjacent to or in front of their homes. This process offers residents a structured way to resolve disputes regarding new tree plantings within their adjacent parkways and ensures that decisions regarding trees are made objectively and comply with local laws, regulations, and ordinances.

The Tree Refusal Process requires the property owner to submit a written formal request for refusal of a tree with a statement listing their reasons for refusal. The following reasons are not eligible for refusing a tree and will not be considered through this process:
a. The property owner does not want a tree on their property. b. The tree will produce fruiting or leaf litter.
c. The tree will block views.
d. The tree has the potential to cause root damage in the future. e. The property owner perceives the tree to be a fire hazard. f. The property owner does not want to pay irrigation costs for the tree.

Such appeals would be reviewed by the Parks & Recreation Commission, and a recommendation by the Commission will be forwarded to the City Council for final review and decision. The City Council determination will not be subject to appeal.

Staff will continue to educate property owners through the implementation of this process about the importance of trees, proper tree care, and the environmental benefits they provide to help reduce misconceptions about trees and build more understanding and support for the City’s reforestation efforts. The process supports long-term planning for

urban forestry and green infrastructure and ensures that decisions regarding trees align with broader community goals and objectives.

Protection of Large Native Trees
The updated Management Plan also provides for the protection of Large Native Trees in a manner similar to Heritage Trees. Large Native Trees are defined in the Management Plan as a tree that is indigenous to Riverside County and has a diameter of 30 inches or greater at breast height (4.5 feet above ground). For a listing of native trees, visit Search California Native Plants (calscape.org).

The Large Native Tree Protection allows for existing established native trees that are either in the public right of way, parks, or general open spaces to be protected from removal. This policy may also apply to private trees with the written consent of the owner of the real property on which the private tree is located at the time the designation is made. Trees protected under this policy include those that may be impacted by construction activities or development of the area. The trees would be evaluated by an Arborist to ensure their health and safety, and the City would make efforts to protect them or relocate them. In cases where it is not feasible to retain the trees and removal is deemed necessary, the trees would be replaced at a 2:1 ratio indicated in the Management Plan with a City approved tree species.

CHAPTER 12.22 AMENDMENTS
City staff is also recommending amendments to CMC Sections 12.22.030 and 12.22.050 to make changes consistent with the updates to the Management Plan and to clarify the responsibilities of the City with respect to the maintenance of City trees and shared responsibility trees.

Chapter 12.22 of the Management Plan states that the City is responsible for the planting and maintenance (other than watering) of shared responsibility trees. Shared responsibility trees are defined as trees planted within a parkway at the City’s express written direction and approval. Property owners are responsible for, among other things, properly watering shared responsibility trees.

The proposed ordinance would clarify that the City’s tree maintenance obligations, if any, are limited to those placed on the City by applicable state laws, rules, or regulations, including, but not limited to, any case law governing the City’s responsibility with respect to avoiding a dangerous condition of public property.

FINANCIAL IMPACT:

Approval of the recommended actions will result in no additional appropriation of funds as prior approval of $413,000 is already in place for the upfront cost of the contractual obligation with the landscape contractor. Residential Pay Program revenue estimates will be included with the proposed fees for the October 16, 2024 meeting.

ENVIRONMENTAL ANALYSIS:

This action is exempt pursuant to Section 15061(b)(3) of the Guidelines for the California Environmental Quality Act (CEQA), which states that a project is exempt from CEQA if the activity is covered by the commonsense exemption that CEQA applies only to projects that have the potential for causing a significant effect on the environment. Where it can be seen with certainty that there is no possibility that the activity in question may have a significant effect on the environment, the activity is not subject to CEQA. This action is to approve updates to the Urban Forest Management Plan and CMC Chapter 12.22, and there is no possibility that this project will have a significant effect on the environment.

Therefore, no environmental analysis is required.

ORDINANCE NO. 3401

AN ORDINANCE OF THE CITY OF CORONA,
CALIFORNIA, AMENDING SECTIONS 12.22.030 AND

12.22.050 OF THE CORONA MUNICIPAL CODE
REGARDING THE CITY’S RESPONSIBILITIES FOR

MAINTENANCE OF TREES IN PARKWAYS
WHEREAS, Article XI, § 7 of the California Constitution authorizes cities to make and enforce within their limits all local, police, sanitary, and other ordinances and regulations not in conflict with general laws; and
WHEREAS, Corona Municipal Code (“CMC”) Chapter 12.22 establishes guidelines for the care and management of City trees and shared responsibility trees within the City; and
WHEREAS, CMC Section 12.22.050(C) sets forth the responsibility of property owners and the City of trees and landscape materials within parkways; and WHEREAS, the City Council desires to amend CMC Section 12.22.050 to clarify the standards that will apply for the planning, planting, maintenance, alteration and removal of all City trees, shared responsibility trees and landscape materials within parkways.

NOW, THEREFORE, THE CITY COUNCIL OF THE CITY OF CORONA
DOES ORDAIN AS FOLLOWS:

SECTION 1. Section 12.22.030 (Definitions). Section 12.22.030 (Definitions) of Chapter 12.22 (Community Urban Forest and Landscape Guidelines) of Title 12 (Streets, Sidewalks and Public Places) is hereby amended by revising subsection (L) and (M) and adding subsection (N) to read as follows:
“(L) “Public property maintenance objectives” means tree maintenance obligations, if any, placed on the city by applicable state laws, rules or regulations, including, but not limited to, any case law governing the city’s responsibility with respect to avoiding a dangerous condition of public property.
(M) “Urban forest” means the collection of city trees and shared responsibility trees located within the city. Also sometimes referred to as the Community forest.
(N) “Urban forest management plan” means the plan duly
adopted with such title, or with a similar title and City Council intent to serve as such plan, as approved by resolution of the City Council.

JAMIER\14100.14001\10298393.1
The Urban Forest Management Plan shall be deemed to be a part of this chapter and enforceable as such.”
SECTION 2. Section 12.22.050 (Parkways – responsibilities of property owners and city). Section 12.22.050 (Parkways – responsibilities of property owners and city) of Chapter

12.22 (Community Urban Forest and Landscape Guidelines) of Title 12 (Streets, Sidewalks and Public Places) is hereby amended in its entirety to read as follows:
“12.22.050 Parkways - responsibilities of property owners and city.
(A) Findings.
(1) The city acknowledges that trees provide
environmental, aesthetic, social and economic benefits to property owners and to the public at large. Specifically, trees increase property values, provide aesthetic value, provide shade and cooling, reduce energy costs, decrease wind velocities, provide erosion control, conserve energy, reduce stormwater runoff, and act as filters for airborne pollutants, reduce noise, provide privacy, provide wildlife habitat and food, sequester carbon, and release oxygen. (2) Trees also present their share of challenges. Those challenges can include, but are not limited to: (1) invasive and shallow root structures, which can cause damage to sewer and water lines, sprinkler systems, sidewalks, driveways, patios, and other hardscape, and even foundations of homes; and (2) limbs which fall or drop , causing damage to persons and property. While these challenges can occur even with properly watered and maintained trees, they are more likely to occur when trees are poorly watered and maintained.
(3) The proper care for shared responsibility trees is a shared responsibility of property owners and city government, because not only does the public at large benefit from shared responsibility trees, but the property owner personally and uniquely benefits from their particular shared responsibility tree. Property owners therefore are solely responsible for watering trees on their own property, even when those trees are shared responsibility trees.

In addition, while there is no way in which to entirely control where the roots of trees travel, proper and adequate watering of trees is the principal manner in which to mitigate the impacts of roots.

Accordingly, property owners are solely responsible for the effects caused by the roots of the trees on their own property, even when

JAMIER\14100.14001\10298393.1
those trees are shared responsibility trees, including the effects caused by improper or inadequate watering of any such trees. The city is responsible for periodically evaluating and trimming or otherwise maintaining (other than watering) shared responsibility trees, and removing such trees when the city is on notice that a tree poses an undue risk of danger to person or property; provided, however, that nothing provided for in this Chapter 12.22 or elsewhere in this code or the urban forest management plan shall require the city’s responsibilities to exceed that which is required by the public property maintenance objectives, as defined in Section

12.22.030 above.
(B) Standards. The planning, planting, maintenance, alteration and removal of all city trees, shared responsibility trees and landscape materials shall be done in compliance with the public property maintenance objectives, as defined in Section 12.22.030 above, this code, including, but not limited to, Chapter

8.32 (Property Maintenance), Chapter 12.08 (Excavations in Public Rights-of-Way), and Chapter 17.70 (Landscaping, Fences, Walls, Hedges), as well as the Urban Forest Management Plan and any other applicable guidelines adopted by the city, including, but not limited to, the Residential Parkway Landscape Conversion Guidelines, the Landscape Design Guidelines for Residential Development, and the Landscape Design Guidelines for
Commercial Development.
(C) Responsibilities other than watering. The planning, planting, maintenance (other than watering), alteration and removal of all trees and landscape materials in the parkway, or that encroach on the parkway, are assigned as follows:
(1) Property owner. To the owners of the property on
which a parkway is located or of the property on which the encroaching landscape material originates, except as expressly assigned to the city in Section 12.22.050(C)(2) below. Among other responsibilities, property owners shall remove overgrown trees (other than shared responsibility trees), shrubs and other landscape materials and weeds in the parkway or that encroach on a parkway. (2) City. The city is expressly assigned the responsibility to, in a manner consistent with the standards set forth in Section

12.22.050(B) above, plan, plant, maintain (other than watering), alter and remove the following:

JAMIER\14100.14001\10298393.1
(a) All trees and landscape materials in parkways
maintained as part of a landscape maintenance district or a community facilities district; and
(b) All shared responsibility trees.
(D) Watering. The watering of all trees and landscape materials in parkways is assigned as follows:
(1) Property owner. To the owners of the property on
which a parkway is located, including shared responsibility trees, except as expressly assigned to the city in Section 12.22.050(D)(2) below.

(2) City. The city is expressly assigned the responsibility to water all trees and landscape materials in parkways maintained as part of a landscape maintenance district or a community facilities district.”
SECTION 3. Effective Date. The Mayor shall sign this Ordinance and the City Clerk shall attest thereto and shall within fifteen (15) days of its adoption cause it, or a summary of it, to be published in a general circulation newspaper published and circulated in the City of Corona. This Ordinance shall take effect and be in force 30 days after its adoption.

• FY24 = $628,526
Solution
Residential Pay Program would allow residents to pay out of pocket for requests to trim shared responsibility trees prior to their next scheduled trimming

New Trees Refusal Process
• Provides a pathway for property owners to appeal a new tree planting in residential parkways in front of or on the side of their home.
• A Refusal will not be granted due to not wanting a tree, fruiting, leaf litter, loss of view, future root damage or cost of irrigation.
• Appeals will be brought before the Parks & Recreation Commission for review and consideration. • If the Commission feels the appeal meets the criteria, the appeal would be recommended to the City Council for review and final decision.

Protection of Large Native Trees
• Large Native Trees defined as a tree that is indigenous to Riverside County and has a diameter of 30 in. or greater at breast height (4.5 ft. above ground) • A tree may be designated as a Large Native Tree upon nomination and with written consent of the property owner where the tree is located • Allows for the protection of existing established native trees in the public right of way, parks, or general open space to be protected from removal • Ensures that any identified Native or Heritage tree is updated in the City Tree Inventory
• Ensures that if a tree does require removal that the city replace the trees at the 2:1 ratio outlined in the UFMP and at a location the city will deem suitable

The Ask:

That the City Council approve an amendment to the
Urban Forest Management Plan authorizing:
a. Residential Pay Program for tree trimming
requests outside the grid pruning cycle.
b. Process for residents to appeal newly planted
trees in their parkways.

URBAN FOREST MANAGEMENT PLAN

PURPOSE AND FINDINGS
This Urban Forest Management Plan (“Management Plan”) establishes guidelines and procedures for the care and protection of trees to promote the health, safety, welfare, and quality of life for all Corona residents, business owners and visitors. The City of Corona (“City”) acknowledges that trees provide environmental, aesthetic, social and economic benefits to property owners and to the public at large.

Specifically, trees increase property values, provide aesthetic value, provide shade and cooling, reduce energy costs, decrease wind velocities, provide erosion control, conserve energy, reduce stormwater runoff, and act as filters for airborne pollutants, reduce noise, provide privacy, provide wildlife habitat and food, sequester carbon, and release oxygen.

Trees also present their share of challenges, particularly when not properly watered and cared for. Those challenges can include invasive and shallow root structures, which can cause damage to sewer and water lines, sprinkler systems, sidewalks, driveways, patios, and other hardscape, and even foundations of homes. Poorly watered and maintained trees can also fall or drop limbs, causing damage to persons and property.

The proper care for trees located in Parkways (“Shared Responsibility Trees”) is a shared responsibility of property owners and City government, because not only does the public at large benefit from Shared Responsibility Trees, but the property owner personally and uniquely benefits from their particular Shared Responsibility Tree. Property owners therefore are solely responsible for watering trees on their own property, even when those trees are Shared Responsibility Trees. In addition, while there is no wayin which to entirely control where the roots of trees travel, proper and adequate watering of trees is the principal manner in which to mitigate the impacts of roots. Accordingly, property owners are solely responsible for the effects caused by the roots of the trees on their own property, even when those trees are Shared Responsibility Trees, including the effects caused by improper or inadequate watering of any such trees.

The City is responsible for periodically evaluating and trimming or otherwise maintaining (other than watering) Shared Responsibility Trees, in a manner consistent with the standards set forth in Section

12.22.050(B) of the Corona Municipal Code (“CMC”), as well as removing such trees when the City is on notice that a tree poses an undue risk of danger to person or property.

This Management Plan allows the City to implement best management practices as reflected by professional tree care industry standards for the planting, maintenance, removal, protection, pruning, and preservation of trees on City owned or controlled property, including Shared Responsibility Trees, as well as to enforce the applicable provisions of CMC, including, but not limited to, Chapter 12.22 (Community Urban Forest and Landscape Guidelines). By helping to assure the preservation and protection of the Urban Forest through regulations and standards of care, our natural resources will continue to enhance the landscape, streets, and parks, while helping to improve the City.

This Management Plan is consistent with the City’s goals and objectives, including those outlined in CMC Chapter 12.22 (Community Urban Forest and Landscape Guidelines). Following this Management Plan will therefore support the CMC and thereby help to ensure that the Urban Forest is being maintained and utilized to meet the City’s standards.

DEAND\14100.14001\10298378.8
The City believes that sustaining the urban canopy, creating visually aesthetic landscaping, and maintaining and encouraging a diversity of trees, both in terms of age and species, will increase the value of our Urban Forest, making it an even greater asset to the City’s residents.

The development of this Management Plan was made possible through a partnership with the California Urban Forests Council and the Western Chapter International Society of Arboriculture, utilizing funding from Proposition 68, administered through CAL FIRE’s Urban and Community Forestry Grant Program.

X. Tree City USA: A nationwide designation that provides a framework for communities to manage and expand their public trees.

DEAND\14100.14001\10298378.8
Y. Tree Correction: The practice of root pruning, installing root barriers, or any other construction or repair work designed to prevent or mitigate a tree’s trunk growth or root system from causing damage to infrastructure.

Z. Tree Injury: A wound or other damage to a tree resulting from any activity, including, but not limited to, Excessive Pruning, cutting, Trenching, excavating, altering the grade, paving or Compaction around a tree, applying an herbicide or other poison, pests or other disease, a vehicle accident, or any other action leading to the death or permanent damage of a tree. Tree Injury shall include, but is not limited to, bruising, scarring, tearing, or breaking of roots, bark, trunk, branches, or foliage.

AA. Tree Protection Zone (TPZ): An area where construction and preconstruction activities are prohibited or restricted to prevent injury to trees required to be preserved pursuant to Section 5 of this Management Plan.

BB. Tree Risk Assessment: A visual and/or physical assessment of a tree (including sometimes its roots, stem, or crown) performed by an ISA certified person to provide the City with an increasingly more detailed assessment of the tree’s condition, as well as a report of their observations, any tree defects and, when necessary, options regarding measures that may be taken, including maintenance, mitigation, or removal. There are three (3) levels of Tree Risk Assessments: Level 1 (Visual Tree Inspection); Level 2 (Basic Assessment); and Level 3 (Advanced Assessment).

CC. Trenching: Any excavation to provide irrigation, install foundations, utility lines, services, pipe, drainage, or other property improvements below grade.

DD. Urban Forest: The collection of City Trees and Shared Responsibility Trees located within the City of Corona. Also sometimes referred to as the Community Forest.

DEAND\14100.14001\10298378.8
SECTION 2 TREE CATEGORIES
For the purposes of this Management Plan, the following categories of trees are defined as:

A. Private Trees: As defined in CMC Section 12.22.030. Currently, they are defined as trees which meet either of the following criteria: (1) planted on property which is not owned by the City and which is not within a Parkway; or (2) planted within a Parkway without the City’s express written direction and approval. While referenced, this Management Plan does not provide guidance or regulation for any Private Trees.

Examples: Such treesinclude, but are not limited to, trees planted on private residential or nonresidential property or on property owned by public agencies other than the City, including trees planted within a Parkway if not planted at the City’s express written direction or approval.

B. Shared Responsibility Trees: As defined in CMC Section 12.22.030. Currently, they are defined as trees which meet all the following criteria: (1) planted on public or private property; (2) planted within a Parkway; and (3) planted at the City’s express written direction and approval.

Examples: Such trees are expressly limited to those planted in a Parkway at the City’s express written direction and approval.

C. City Trees: As defined in CMC Section 12.22.030. Currently, they are defined as trees planted by or at the direction of the City on property owned or fully controlled by the City and which is not within a Parkway.

Examples: Such trees include, but are not limited to, park trees, trees planted in street medians, trees planted in LMD and CFD designated areas, trees planted on other property owned in fee by the City (e.g., City Hall, Public Library etc.).

DEAND\14100.14001\10298378.8
SECTION 3 TREE INSPECTIONS / TREE INVENTORY
A. Applicability
This Section 3 (Tree Inspections/Tree Inventory) shall apply only to City Trees and Shared Responsibility Trees.

B. Pre-Pruning Visual Tree Inspection - Objectives and Procedures A Visual Tree Inspection of City Trees and Shared Responsibility Trees shall be done before they are pruned to identify visually obvious problems or risks, and may result in a recommendation for a higher level Tree Risk Assessment if no immediate risk is identified. If further evaluation is needed, a Level 2 or Level 3 Tree Risk Assessment should be performed by a City Arborist in their discretion.

The Pre-Pruning Visual Tree Inspection shall include:
• General condition/branch architecture/health;
• Identification of the type of branches to reduce or remove (e.g., dead, overextended, interfering, needing clearance) and location (e.g., over house, under wires); • Number of branches to be removed or reduced (number, diameter, or percentage); • Type of cuts to use (branch removal, reduction, heading, or shearing); • Signs of wildlife nesting; and
• Worker safety concerns (e.g., root collar buried, powerlines, bees, tree defects).

Each City Tree and Shared Responsibility Tree should receive a Visual Tree Inspection at least once every seven (7) years (e.g., as part of a routine trimming program or inventory update). Notably, routine tree pruning program Visual Tree Inspections do not assign a severity level or mitigation time frame to tree risk; they simply point out a tree condition that requires further evaluation by the City Arborist.

Accordingly, supplemental Visual Tree Inspections and higher level Tree Risk Assessments, as further discussed in Section 3(E) (Tree Risk Assessments) below, should be done as needed and as determined by the City Arborist.

As discussed in more detail in Section 3(D) (City Tree Inventory) below, pruning work history data shall be tracked and monitored within the City’s tree inventory management program (“City Tree Inventory”) that allows for documented work history to be recorded and accessible. This City Tree Inventory should include all City Trees and Shared Responsibility Trees, as determined by the CityArborist. TheCity should frequently review the inventory for potential high-risk trees and should assign such trees to have Tree Risk Assessments done by the City Arborist or other qualified professional, with written documentation, as often as necessary in the determination of the City Arborist.

Those performing Pre-Pruning Visual Tree Inspections must adhere to current industry standards, to ensure they are being done on a consistent and regular manner. Currently, such standards include the American National Standards Institute (ANSI) A300 standards and ISA Best Management Practices.

DEAND\14100.14001\10298378.8
C. The Process of Identifying and Documenting Inspections Inspected items should include, but are not limited to:

1. Lean/root problems: for example, leaning trees with roots heaving out of the ground.

2. Codominant or multiple trunks: competing stems that grow bark between a tight crotch union can be weakened areas prone to failure.

3. Trunk cavities, cankers, mushrooms, and decay: these are indicators of potential internal decay of a tree and, if discovered, may require further investigation and mitigation.

4. Cracks in trunks and branches: these can be indicators of future failures and, if discovered, may require further investigation and mitigation.

5. Weakly attached scaffold limbs and branches: a branch that developed as a reactionary shoot can be predisposed to failure and, if discovered, may require further investigation and mitigation.

6. Hanging or broken branches(hangers): branchesthat are detached from where they were grown and are hanging and could fall, impacting Potential Targets below. Broken branch stubs should be pruned off properly unless preserved for wildlife habitat reasons.

7. Dead branches (deadwood): branches within a canopy of a tree that no longer produce foliage and have begun to lose bark.

8. Pests and other diseases: identified pests that can cause tree failures such as boring, leaf chewing and leaf sucking insects or pathogenic fungus.

While most Visual Tree Inspections can be conducted from the ground, there are times when an aerial inspection may be advisable, as determined by the City Arborist.

D. City Tree Inventory
One of the goals of the Visual Tree Inspections is to create and maintain the City Tree Inventory, as part of the City’s Tree Inventory program. Such program should include:

1. Documenting tree condition and recording dates based on work performed through the City’s tree management program.

2. Identifying vacant sites suitable for trees to be planted.

3. Maintaining trees proactively, instead of reactively as budget allows.

4. Identifying the dollar value of each tree and total Urban Forest utilizing the Trunk Formula Method in accordance with the current guide for plant appraisal.

5. Documenting work history records.

6. Scheduling tree maintenance work.

7. Improving tree structure and health through scheduled tree maintenance.

8. Reducing tree loss and liability.

9. Demonstrating due diligence via work history.

10. Identifying trees that can be salvaged or corrected with proper pruning.

DEAND\14100.14001\10298378.8
E. Tree Risk Assessments
If a Visual Tree Inspection identifies a possible risk, further evaluation of the tree shall be conducted by the City Arborist with the objective to mitigate risk. Except in exigent circumstances, as determined by the City Arborist, a Tree Risk Assessment should be conducted before deciding to remove a tree. However, the City shall not be required to perform a Tree Risk Assessment before removing a tree. A Tree Risk Assessment will be the primary method of further evaluation of all trees.

In terms of ISA best management practices, the City Arborist shall determine the required level of Tree Risk Assessment. If the City identifies a tree that meets the criteria for removal, the tree may be removed as a form of mitigation.

Level 2 and Level 3 Tree Risk Assessments differentiate from a Visual Tree Inspection (Level 1) for reasons that include, as determined by the City Arborist:

1. The use of tools to measure potential defects.

2. Considers Potential Target zones, site history, conditions, potential load, and species failure profile.

3. Develops a report to determine the likelihood and consequences of failure, provides mitigation options, and provides recommendations for a re-inspection cycle or further evolution.

After a Tree Risk Assessment is completed, the City shall conduct the recommended mitigation measure(s), if any, as soon as necessary as determined by the City Arborist according to the risk assessment, but in no event more than (2) two weeks after receiving the Tree Risk Assessment report.

DEAND\14100.14001\10298378.8
SECTION 4 ROUTINE TREE MAINTENANCE
A. Applicability
This Section 4 (Routine Tree Maintenance) shall apply only to City Trees and Shared ResponsibilityTrees.

These guidelines establish principles of care and maintenance for such trees, including pruning, planting, watering, soil, and nutrient requirements, as well as insect, disease, and fruit control.

B. Shared Responsibility Trees
City Responsibilities
The City is expressly assigned the responsibility to, in a manner consistent with the standards set forth in CMC Section 12.22.050(B), plan, plant, maintain (other than watering), alter and remove the following:
(1) all trees and landscape materials in Parkways that are maintained as part of a landscape maintenance district or a community facilities district; and (2) all Shared Responsibility Trees. It is unlawful for any other person to take any such actions with respect to a Shared Responsibility Tree.

Property Owner Responsibilities
As provided for in CMC Section 12.22.050, the owners of the property on which a Parkway is located are responsible for the following:

1. Watering. To accept, protect and adequately and properly water any Shared Responsibility Tree in their Parkway. At a minimum, such property owner shall comply with the provisions of Section 4(H) (Proper Watering of Shared Responsibility Trees) below.

2. City Notification. To notify the Community Services Department of any suspected Hazardous Tree Condition or other potential injury to, or maintenance needs of, any Shared Responsibility Tree in their Parkway.

3. Leave and Deadfall Collection and Disposal. To promptly and routinely remove and dispose of in an appropriate waste receptacle any of the following which are found to be located on the sidewalk or other area of the Parkway that people are likely to use for walking, bicycling or other activities: (i) all fallen leaves and other deadfall from any tree, including from any Shared Responsibility Tree in their Parkway; and (ii) any other debris and dead or otherwise removed landscape material located on the sidewalk or other area of the Parkway that people are likely to use for walking or other activities.

4. Impacts to Dripline Area. To prevent any and all improvements, installations or other impacts within the Dripline Area of a Shared Responsibility Tree that could in any way reasonably be expected to damage the root system, compact the soil over the roots, or impede the free passage of water, air or fertilizer to the roots of the Shared Responsibility Tree.

C. Standards for Tree Maintenance

DEAND\14100.14001\10298378.8
All City maintenance work, including pruning, on City Trees and Shared Responsibility Trees shall be in accordance with the current edition of the following industry standards: ANSI A300 and ANSI Z133.

D. Pruning Methods for Trees
There are seven types of pruning that may be appropriate for the City to conduct on City Trees and Shared Responsibility Trees. They are:

1. Structural pruning: a type of tree pruning for young trees that establishes a strong central leader and develops subordinate branches. Structural pruning helps to alleviate future failures.

2. Crown cleaning: the selective removal of dead, diseased, detached, and broken branches.

No live foliage is to be pruned during crown cleaning, and this is the preferred pruning type for mature trees.

3. Crown thinning: the selective removal of small live branches to reduce crown density. No more than 25% of live foliage should be removed in a growing season.

4. Crown raising: the selective removal of branches to provide vertical clearance.

5. Crown restoration: the selective removal of branches,sprouts and stubs from trees that have been topped.

6. Crown reduction: the selective removal of branches and stems to decrease the height and/or spread of a tree.

7. Utility pruning: the selective removal of branches and stems to reduce growth away from utility lines.

Forroutine pruning, the current edition of ANSIA300 (Part 1) Pruning and ISA Best Management Practices Pruning Third Edition shall define the pruning method.

Pruning may be done outside of a routine trimming program if the prune will satisfy at least one of the following criteria:

1. Accomplishing a mitigation measure identified as part of a Tree Risk Assessment.

2. Improved tree structure.

3. Establish a “dominant leader” (developing trunk) in a young tree.

4. Clearance for new or existing infrastructure.

5. Residential Pay Program:
a. Property owners may opt to pay for additional pruning outside of the scheduled routine pruning for aesthetic reasons or to reduce leaf litter or fruiting. b. Property owners would be required to pay for the additional tree pruning at the thencurrent price schedule of the City’s pruning contractor or as set forth in the City’s master fee schedule prior to the City scheduling the service; pruning would typically occur within 2-3 weeks after payment is received.
c. The following pruning options will be offered, each of which shall comply with ISA standards:

Clearance Prune
Aesthetic Prune
Park/Slope Aerial

DEAND\14100.14001\10298378.8
Slope Climb
Climbing and pruning practicesshall not cause a Tree Injury, except for the pruning cuts. It is best to clearly identify a pruning objective and then select the pruning type most suitable to achieve that objective. For example, if the objective is roadway clearance, crown raising would be the selected type of pruning.

E. Tree Care for Birds and Other Wildlife in City Projects The City utilizes consultants to ensure compliance to the many federal and state laws pertinent to wildlife, tree care, and landscape industry in California. Of note is the Migratory Bird Treaty Act. The City shall make sure that tree care workers hired by the City are qualified with proper training on inspecting for birds and other wildlife during tree care operations. The current edition of Tree Care for Birds and Other Wildlife Best Management Practices in California should be the City’s guiding document for managing wildlife habitat as it pertains to trees, including the Tree Care for Birds and Other Wildlife Best Management Practices Project Preparation Procedure which is attached hereto as Appendix A and incorporated herein by reference (“Project Preparation Procedure”). City staff working in trees and any tree contractor hired by the City shall utilize such Project Preparation Procedure to determine the best plan of action to eliminate harm done to birds and other wildlife.

F. Plant Health Care Plan and Integrated Pest Management The City shall develop a comprehensive plant health care program with the goal of managing the health, structure, and appearance of plants and trees under its care (“Plant Care Program”). As part of that Plant Care Program, there shall be an Integrated Pest Management (“IPM”) strategy (“IPM Strategy”). The IPM Strategy shall be a method of controlling plant pests by combining biological, culture, mechanical, physical, and/or chemical management strategies. The City’s IPM Strategy shall be constructed based on the IPM Flowchart attached hereto as Appendix B and incorporated herein by reference (“IPM Flowchart”). The IPM Flowchart is based on ANSI A300 standards and shall dictate the City’s plan of action when there is an identified plant health concern.

The pest source shall be identified and targeted with a specific and timely treatment. All prescriptions for pesticides are to be issued by a Pest Control Advisor and applied by Pest Control Applicators. If it appears that insects or disease may lead to the death of a City Tree or Shared Responsibility Tree, then the City may evaluate the condition according to the following guidelines and treat the problem in a timely fashion to prevent further decline of the tree.

1. For treatment of insects, the Pest Control Advisor shall be consulted. Nontoxic materials shall be used whenever feasible. All chemicals must conform to the California Department of Pesticide Regulations.

2. For disease and decay that erodes the health or weakens the structure, further analysis by an arborist may be required to evaluate the stability.

3. Diseases below ground are often caused by poor landscape design surrounding old trees, which encourages harmful and often lethal ailments. This could include fungi, rot, and other decay. The following conditions favor such disease:

DEAND\14100.14001\10298378.8
a. Compaction of the soil within the tree’s Dripline Area; b. Removing soil from the tree root area;
c. Excessive watering on or near the tree trunk;
d. Planting incompatible plants within the tree’s Dripline Area.

When planning landscaping around a City Tree or Shared Responsibility Tree an evaluation of the tree and soil must be performed by the City Arborist to determine if there is disease present. If the tree is diseased and it is reasonable to expect that landscaping will contribute to decline, permanent damage, or render it hazardous, the City may take measures to reduce or eliminate the conditions that may cause the decline of the City Tree or Shared Responsibility Tree
G. Fertilizing
Fertilizers shall only be applied if specified by the City Arborist as part of the Plant Care Program for City and Shared Responsibility Trees. Fertilizing may be specified for trees that will be impacted by an upcoming disturbance, grade change, or a modified environment. Fertilizing in these instances may aid the tree to overcome the stress caused by disturbance.

H. Proper Watering of Shared Responsibility Trees
The owners of the property on which a Parkway is located are responsible for accepting, protecting, and adequately and properly watering any Shared Responsibility Tree in their Parkway. Adequate and proper watering of trees necessitates deep watering, which involves slowly watering with an amount of water appropriate to the age and species of the tree, as well as the season. Surface watering, like the way in which lawns are watered, is not an adequate way in which to water a tree and must be avoided. While deep watering encourages roots to grow down, surface watering with sprinklers encourages roots to grow invasively along the surface and create hazards or damage to sewer and water lines, sprinkler systems, sidewalks, driveways, patios, and other hardscape, and even foundations of homes. Poorly watered and maintained trees can also fall or drop limbs, causing damage to persons and property.

There are a variety of ways in which to adequately and properly deep water trees, so property owners should educate themselvesin how to do so in a mannerthat worksforthem. At a minimum, property owners should keep the following in mind:

1. Tree Establishment Period. Newly installed trees, including drought tolerant species, are dependent upon supplemental irrigation until established (“Establishment Period”).

Providing a watering well around the Dripline Area during this Establishment Period is also recommended, as well as applying mulch around the trunk area to retain moisture. If a tree is native to areas of higher rainfall, then the tree will require supplemental water throughout its life cycle. Periods of extreme heat, wind or drought may require even more supplemental water.

2. Reclaimed Water. If reclaimed water is to be used, the species of trees to be irrigated should have an elevated tolerance of salts.

3. Sample Techniques. You can deep water trees in a variety of ways, including, but not

DEAND\14100.14001\10298378.8
limited to, using a soaker hose or drip system that slowly applies water to the soil in and around the Dripline Area over several hours, or you may use perforated piping installed in the ground to apply water directly to the root zone. An automatic sprinkler system may be used as well, but must be designed and programmed appropriately. For instance, you can install a “bubbler” or similar sprinkler with the perforated piping noted above. Providing a watering well for newly planted or establishing treesis also recommended in addition to applying mulch around the trunk area to retain moisture.

4. Educational Materials. TheCitywillseek to develop and disseminate deep watering and other tree watering guide educational materials, asfurther discussed in Section 10 (Education and Community Outreach). Property owners should also reach out to the Community Services Department to obtain such educational materials.

I. Proper Watering of City Trees
The City Arborist will develop and implement appropriate watering techniques and schedules for all City Trees.

J. Fruit Control
While many trees produce flowers or fruit, some trees can require additional or different maintenance due to the debris generated by the tree. The City Arborist may recommend treatments as part of the Visual Tree Inspection process. For example, the dropping fruit of the European Olive (Olea europaea), American Sweetgum (Liquidambar styraciflua), or acorn drip of a Holly Oak (Quercus ilex) should be considered if it is in the proximity of an ADA accessible ramp or other pedestrian area.

For City Trees, if control measures are warranted as determined by the City Arborist, they shall be prescribed by a Pest Control Advisor and administered by a Pest Control Applicator to ensure successful application of treatment materials.

DEAND\14100.14001\10298378.8
SECTION 5 PROTECTION OF TREES DURING CONSTRUCTION
A. Applicability
This Section 5 (Protection of Trees During Construction) shall apply only to City Trees and Shared Responsibility Trees.

B. Tree Protection Objectives
The objective of this section is to reduce the negative effects of construction on City Trees and Shared Responsibility Trees. Tree protection should begin before construction starts. Successful tree preservation occurs when designers, construction personnel, and project managers are committed to tree preservation.

All members of the project team must be familiar with the rudimentary aspects of tree growth and development to understand the relationship between tree survival and construction practices. Helping to ensure that the City Arborist has input on public and private projects that may impact City Trees or Shared Responsibility Trees will ensure everyone is understanding of the needs regarding trees.

Notwithstanding, all trees cannot and should not be preserved. Trees that are structurally unstable, dead, in poor health, or unable to survive the effects of construction become a liability to the project and may have to be removed.

C. Enforcement – Conditions of Project Approval
The Director shall work with the Community Development Department, Public Works Department, Utilities Department, and any other departments to adopt any laws, rules or regulations necessary to ensure that conditions of approval are included in any public or private construction projects that may impact City Trees or Shared Responsibility Trees.

D. Site Plan
For all projects that require a site plan (including demolition, grading, irrigation, electrical, landscape, etc.), each site plan must indicate accurately plotted trunk locations and the Tree Protection Zone (“TPZ”) of all trees or group of trees to be preserved within the project area. Additionally, for all trees within the project area, the site plans shall accurately show the trunk diameter, Dripline Area and clearly identify the TPZ. The type of protective fencing shall be specified and indicated with a bold dashed line.

Site plans shall also include the following minimum information:

1. Surveyed tree locations, species, size (height, width, DBH). Dripline Area (including trees located on neighboring property that overhang or are within 25 feet of the project site) and City Trees adjacent to the project site.

2. Paving, concrete, Trenching, or grade change (including the limits of over- excavation) located within the Tree Protection Zone (TPZ).

3. Existing and proposed utility easements.

4. Surface and subsurface drainage and aeration systems to be used.

5. Walls, tree wells, retaining walls and grade change barriers, both temporary and permanent.

DEAND\14100.14001\10298378.8

6. Landscaping, irrigation, and lighting within Dripline Area, including all lines, valves, etc.

E. Tree Protection Zone
During the design phase of the project, the City Arborist and the project manager (or other person assigned by the person or entity responsible for the project) will work together on developing the TPZ for each tree impacted by the project. If an unresolved disagreement arises between the City Arborist and the project manager on the size of a TPZ for a tree, the dispute shall be brought to the Director, who will render a final decision on the size of the TPZ.

Each tree to be retained shall have a designated TPZ identifying the area sufficiently large enough to protect it and its roots. Improvements or other activities, such as paving, utility and irrigation trenching, and other ancillary activities shall occur outside the TPZ, unless otherwise specified by the City Arborist. The protection fence shall serve to delineate the TPZ on the project site.

Activities prohibited within the Tree Protection Zone include:

1. Parking vehicles or equipment, storage of building materials, refuse, or excavated soils, or dumping poisonous material on or around trees and roots. Poisonous materials include, but are not limited to, paint, petroleum products, concrete, stucco mix, dirty water or any material that may be harmful to tree health.

2. The use of tree trunks as a backstop, winch support, anchorage, as a temporary power pole, signpost, or other similar function.

3. Cutting of tree roots by utility Trenching, foundation digging, placement of curbs and trenches, or other miscellaneous excavations without prior approval of the City Arborist and report of recommendations.

4. Soil Disturbance or grade change.

5. Drainage changes.

F. Verification of Tree Protection
Following consultation with the City Arborist, the project contractor shall verify in writing that all preconstruction TPZ conditions have been met as follows:

1. Tree fencing installed.

2. Erosion control secured.

3. Tree pruning completed.

4. Soil Compaction preventive measures installed.

5. Tree maintenance schedule established, and the responsible party designated.

6. Tree Protection Zone (TPZ)
G. Activities During Construction and Demolition Near Trees Soil Disturbance
Soil Disturbance or other damaging activities within the TPZ are prohibited unless approved by the City

DEAND\14100.14001\10298378.8
Arborist.

Trenching, Excavation and Equipment Use
Trenching, excavation or boring within the TPZ shall be limited to activities approved by the City Arborist (or the Director).

If Trenching is unavoidable, the City Arborist may recommend allowing trenches up to the following distances away from the tree:

TRUNK DIAMETER
(measured at 4.5 feet above natural grade)

DISTANCE FROM THE TRUNK ON

BOTH SIDES
Up to 9 inches 5 feet
10-14 inches 10 feet
15-19 inches 12 feet
over 19 inches 15 feet
Alternative Methods for Hardscape Maintenance and Installation to Prevent Root Cutting The following remedies should be considered as an alternative to severing tree roots:

1. Grinding a raised walkway or concrete pad

2. Ramping the walkway surface over the roots or lifted slab with pliable paving

3. Re-routing the walkway around tree roots

4. Permeable paving materials (e.g., decomposed granite), interlocking pavers, or flagstone walkways on sand foundations

5. Root bridging
H. Tree Maintenance During Construction
Providing adequate maintenance can mitigate stressful changes that occur to a tree’s environment during construction. To remain vigorous, the tree needs to maintain stored carbohydrates and preserve the effectiveness of its growth regulators.

The City Arborist may therefore also require that projects provide certain maintenance activities, such as the following:

Irrigation
Providing supplemental irrigation for trees under water stress may be the single most important treatment.

Irrigation should be designed to wet the soil within the TPZ to the depth of the root zone

DEAND\14100.14001\10298378.8
and to replace that water once it is depleted. Light, frequent irrigation should be avoided. Create a six-inch berm around trees at the edge of the TPZ and fill with no more than six inches of mulch. Fill the basin with water. Irrigation should wet the top two to three feet of soil to replicate similar volumes and normal seasonal distribution.

Soil Compaction Mitigation
To prevent negligent encroachment into the TPZ, trees to be preserved during construction must always have the specified type of protection fences in place. Removal of fences, even temporarily, to allow deliveries or equipment access is not allowed unless approved by the City Arborist and a root buffer is installed. The root buffer components: mulch, gravel, and plywood, must be maintained continually to assure its effectiveness against soil Compaction.

Dust Control
During periods of extended drought, wind or grading, trunks, limbs, and foliage should be sprayed with water to remove accumulated construction dust.

DEAND\14100.14001\10298378.8
SECTION 6 TREE REMOVAL
A. Applicability
This Section 6 (Tree Removal) shall apply only to City Trees and Shared Responsibility Trees.

B. Tree Removal Policy; Tree Replacement Ratio
Tree Removal Procedures
City Trees and Shared Responsibility Trees have value to the City and the public. As such, it is the policy of the City to preserve such trees whenever reasonably practical, considering risk mitigation and other legitimate considerations. All efforts will be made to preserve healthy trees that do not meet the criteria for removalset forth below or that otherwise pose a risk. Trees will not be considered for removal based upon leaves, fruiting or sap droppings, blocking of sites or views, interference with solar panels, or cost of irrigation. Trees that may be impacted by construction or new development should be protected in place where feasible or replaced at a 2:1 ratio, as described below, if removal is deemed necessary pursuant to this Management Plan. The Community Services Department will review and evaluate existing trees that will be impacted by construction activities or new development during the planning review phase. There are certain conditions in which a tree must be removed, however, as outlined in this Section. Unauthorized tree removals that occur in violation of this Management Plan will be enforced pursuant to the provisions of the Corona Municipal Code Chapter 1.08.

Tree Replacement Ratio
When practical, every City Tree or Shared Responsibility Tree removed should be replaced, at the same location and/or elsewhere in the City, at a 2:1 ratio with a new species selected from the City’s Approved Tree List provided for in Section 8 below.

C. Removal Criteria
Trees will be removed only when the Director determines that one or more of the following criteria are met:

1. The City Arborist determines that the tree is in a state of decline due to any Tree Injury and is unlikely to return to good health.

2. The City Arborist determines that the tree poses a safety risk that cannot reasonably be mitigated or avoided by a Tree Correction method or where an unreasonable safety risk would be created by the Tree Correction method which would have been recommended by the City Arborist.

3. The City Arborist determines that the Tree Correction method(s) which would have been recommended by the City Arborist will likely kill the tree or render it a hazardous tree.

4. The City Arborist determines that the tree interferes with the growth and development of a more desirable tree.

5. The Director determines that, based upon advice from the City Arborist or other expert or City official or employee, the tree has caused, is causing or imminently will be causing damage to public or private infrastructure and that no Tree Correction method is reasonably likely to prevent such damage.

DEAND\14100.14001\10298378.8

6. The City Arborist determines that the tree is planted in an improper location.

7. The City Arborist determines that the tree is an invasive species for the area.

8. For any other reason which is in the best interest of the public health, safety, or welfare, as determined by the City Manager or his or her designee.

Sidewalk Lifts
If the root system of a City Tree or Shared Responsibility Tree has been found to be elevating the sidewalk to a degree greater than a quarter of an inch where the tree’s removal is not recommended, the sidewalk repair will bemade using an approved replacement or modification method which best correctsthe sidewalk anomaly while minimizing harm to the tree.

D. Tree Evaluation for Removal
If a City Tree or Shared Responsibility Tree has been brought to the City’s attention for possible removal, but a Visual Tree Inspection does not reveal apparent and adequate justification for its removal, the City should conduct a higher level Tree Risk Assessment to determine the level of risk and the range of possible mitigation measures. In reviewing the Tree Risk Assessment and assessing the tree’s possible removal, the City Arborist shall refer to the criteria noted in Section 6(C) above. Mitigation pruning or other mitigation measures short of removal will typically be considered first to reduce the risk to a level deemed acceptable by the City Arborist, but if the condition cannot be mitigated or reduced to a level of risk deemed acceptable, then the tree shall be removed. The City has the right, in its reasonable discretion, to implement any of the mitigation measures, considering the noted risks in relation to the benefits of the tree.

E. Appeal Process
If a City Tree or Shared Responsibility Tree is determined by the City to not meet any criteria for removal, but the reporter or owner of the property on which the tree is located wishes to have the tree removed due to personal preference, such person would have the option to utilize the following appeal process:

1. Written Request; Evidence. The person shall submit a written formal request for removal of the tree, with a statement listing their reasons why one or more of the removal criteria listed in Section 6(C) have been met. Along with their statement, the person shall submit to the City any and all evidence supporting their position.

2. Parks & Recreation Commission. The request will be first presented by the Director to the Parks and Recreation Commission. By a majority vote of the members present, the Commission may make a recommendation to the City Council.

3. Planting Cue Card from ISA located in Appendix C.

F. Tree Replacement Guidelines
The following guidelines have been developed to promote the health and safety of City Trees and Shared Responsibility Trees for years to come. These guidelines and specifications are required for any tree planting on City property or within City rights-of-way.

The City has a goal of planting trees in all empty tree wells located on City property or within City rightof-way, provided that it meets the requirements for an appropriate planting site as set forth below. Tree planting is generally scheduled for the spring season between February and May. The tree planted must be selected by the City Arborist from the City’s Approved Tree List provided for in Section 8 below in order to maintain unity of the tree canopy in the area.

The City also has a goal of replacing all trees that are removed pursuant to the Tree Removal guidelines set forth in Section 6 of this Management Plan in a location that meets the requirements for an appropriate planting site. Aplanting site is appropriate if the Director determines that it meets the following conditions:

DEAND\14100.14001\10298378.8

1. Adequate spacing (both aboveground and underground) is present to allow healthy growth to maturity.

2. The location is conducive to good management practices and does not overly disrupt maintenance activities or utilities.

3. Future maintenance, especially water, is available.

4. Funding is available for planting.

G. Refusal Process
If the owner of the property on which the proposed planting site is located wishes to not have the tree planted due to personal preference, such person would have the option to utilize the following refusal process:

1. The person shall submit a written formal request for refusal of the tree, with a statement listing their reasons for the requested refusal. The following reasons are not eligible reasons for refusing a tree and will not be considered through this process:
a. The property owner does not want a tree on their property. b. The tree will produce fruiting or leaf litter.
c. The tree will block views.
d. The tree has potential to cause root damage in the future. e. The tree is perceived by the property owner to be a fire hazard. f. The property owner does not want to pay irrigation costs for the tree.

2. The request would then be reviewed by the Parks and Recreation Commission. By a majority vote of the members present, the Commission would make a recommendation to the City Council.

3. Recommendation would then be reviewed by the City Council. By a majority vote of the members present, the City Council will make a final determination. The City Council determination shall not be subject to appeal.

4. Once the refusal process is completed and the determination is final, the approved action will be executed.

SECTION 9 HERITAGEAND LARGE NATIVETREES
A. Applicability
This Section 9 (Heritage and Large Native Trees) shall apply to City Trees and Shared Responsibility Trees, and may apply to Private Trees with the written consent of the owner of the real property on which the Private Tree is located at the time the designation is made.

B. Designation of Heritage or Large Native Trees
Upon nomination by any person, and for Private Trees with the written consent of the owner of the real property on which the tree is located, a tree may be designated as a Heritage or Large Native Tree.

Nominations for a Heritage or Large Native Tree shall be reviewed and approved by the Community Services Department and Parks and Recreation Commission.

The Community Services Department and Parks and Recreation Commission may designate a tree as a Heritage Tree upon a finding that it is unique and of importance to the community due to any of the following factors:

1. It is one of the oldest and largest of its species located in the City.

2. It is a tree of unique form or species.

3. It has historic significance due to an association with an historic building, site, street, person, or event.

4. It has unique cultural significance that warrants special consideration.

5. It is a defining landmark or significant outstanding feature of a neighborhood which can include significant aesthetic, botanical, or ecological value.

The Community Services Department and Parks and Recreation Commission may designate a tree as a Large Native Tree if it is indigenous to Riverside County and has a diameter of 30 inches or greater at breast height (4.5 feet above ground). Search California Native Plants (calscape.org) C. Once Heritage or Large Native Tree is Designated
Upon Community Services Department approval, the tree shall be designated as a Heritage or Large Native Tree. Any work on or in the vicinity of a designated Heritage or Large Native Tree shall be done in accordance with this Management Plan and under supervision of the City Arborist or another licensed arborist if approved by the City Arborist. The requirement for City Arborist or other licensed arborist supervision may be waived by the Director, or his or her designee, in cases of hazardous trees or other cases where immediate action must be taken for public health or safety reasons.

After Community Services approval of a Heritage or Large Native Tree designation, a listing of trees, including the specific locations thereof, shall be kept by the City within its tree management database.

This information shall be made available to the public through the Community Services Department by way of request. An owner of a Heritage or Large Native Tree may choose to install a plaque or marker at their

DEAND\14100.14001\10298378.8
own cost, but it will not be logged, managed, or maintained by the City. For Private Trees which have been designated to be Heritage or Large Native Trees, the City may require a notice of designation to be recorded against the property with the Riverside County Recorder to provide record notice of such designation.

D. Removal of Heritage or Large Native Tree Designation Once designated, a Heritage or Large Native Tree shall be subject to the provisions of this Management Plan, unless removed from the list of Heritage or Large Native Trees by action of the City. The Community Services Department may remove a tree from the list upon its own recommendation or, for Private Trees, upon written request by the owner of the real property on which the tree is located. Requests for a Heritage or Large Native Tree designation removal must originate in the same manner and proceed through the same process as a nomination for a Heritage or Large Native Tree; provided, however, that the removal of a Heritage or Large Native Tree designation will be approved only when one or more of the following criteria are met:

1. The tree is in a state of decline due to any Tree Injury and is unlikely to return to good health.

2. The tree poses a safety risk that cannot reasonably be corrected or where an unreasonable safety risk would be created by the construction process or root pruning.

3. Work improvements required to be made around the tree will likely kill the tree or render it a hazardous tree.

4. The tree has or is causing damage to infrastructure, such as roads, sidewalks, water mains, sewer laterals or electrical infrastructure and no other alternative repair method is feasible.

5. For any other reason which is in the best interest of the public health, safety, or welfare, as determined by the City Manager and City Attorney in consultation with the Director.

For Private Trees which have been designated to be Heritage or Large Native Trees, the City shall have a notice of removal of designation recorded against the property with the Riverside County Recorder, if a notice of designation had been recorded to provide record notice of such designation.

E. Appeal Process
Any person may appeal the Community Services Department’s decision to designate a Heritage or Large Native Tree, or its decision not to remove of such designation, by utilizing the following appeal process:

1. The person shall submit a written formal request, with a statement listing their reasons for the request. The standard for removal shall be that the burden of the tree remaining on the Heritage or Large Native Tree designation list for the property owner substantially outweighs the benefits to the public of having the tree remain on the list.

2. The request would then be reviewed by the Parks and Recreation Commission. By a majority vote of the members present, the Commission would make a recommendation to the City Council.

3. The Commission recommendation would then be reviewed by the City Council. By a majority vote of the members present, the City Council will make a final determination.

The City Council determination shall not be subject to appeal.

DEAND\14100.14001\10298378.8

4. Once the appeal process is completed and the determination is final, the approved action will be executed.

F. Application to Remove a Heritage or Large Native Tree No person shall remove any living Heritage or Large Native tree on any parcel or property, excluding single-family residential properties, without first obtaining a permit to do so. Applications for a permit to remove one or more Heritage or Large Native Trees shall be made in writing to the Community Services Department. All applications must include the following:

1. The name and residence or business address of the applicant.

2. A map showing the location and size of the trees to be removed.

3. A description of the proposed work, including the number of trees to be removed, the reason for removal, and the applicant’s intent regarding the future use of the property.

4. A tree removal and replacement plan in accordance with this chapter.

The Director may approve the removal of one or more Heritage or Large Native Trees when one or more of the following findings are made:

1. The tree poses a reasonable risk of injury or harm to persons or property.

2. The tree is substantially interfering with the integrity of an existing structure or infrastructure, and no other alternative repair method is feasible.

3. When considering the size, shape, topography, and existing trees on the lot, the denial of the permit would create an unreasonable hardship on the property owner. Redesign of any proposed development as an alternative to removal of an existing protected tree does not create an unreasonable hardship.

4. A written determination has been made by a certified arborist, after a visual inspection or scientific evaluation, that the tree is so diseased or damaged that it is no longer viable or is a threat to persons or property, including other trees.

5. For any other reason which is in the best interest of the public health, safety, or welfare, as determined by the City Manager and City Attorney/LRM Director in consultation with the Director.

When practical, every Heritage or Large Native Tree removed should be replaced, at the same location and/or elsewhere in the City, at a 2:1 ratio with a new species selected from the City’s list of Native Trees in Section X. The replacement trees should be a minimum size of 24” box tree G. Appeals of Decisions to Remove a Heritage or Large Native Tree Tree removal decisions associated with a development project are advisory to the planning review authority as a condition of approval of development. An applicant may appeal any development decision and its conditions of approval pursuant to the appeal process set forth in the zoning code.

Decisions not related to a development project may be appealed by the applicant in writing to the Parks and Recreation Commission pursuant to the Appeal Process set forth in Section 6(E) above.

DEAND\14100.14001\10298378.8
SECTION 10 EDUCATION AND COMMUNITY OUTREACH
A. Applicability
This Section 10 (Education and Community Outreach) shall apply to City Trees, Shared Responsibility Trees, and Private Trees. Accordingly, the City shall provide education and community outreach to benefit all trees within its jurisdiction.

B. Community Forestry Objectives
Education is an integral and primary element of a City’s Urban Forest. Education tempers the use of regulations by empowering citizens. The City believes citizens will act responsibly if given the information they need to make sound decisions.

Distinct educational strategies can be developed to reach a wide range of affected people, including the general public, the development community (property owners, architects, realtors, investors, builders, and contractors), public agencies, and educational institutions. The common factor in educating these groups is to provide them with information about how proper tree planting, maintenance, and protection can contribute to and enrich the quality of life.

Additionally, awareness will be raised surrounding benefits of trees and the Urban Forest.

Information circulation places trees and their care in front of the public and allows them to learn, understand, and relate to the City’s forest management program. Additionally, public tree and Community Forest knowledge is raised, either through the Tree City USA celebrations, City social media, presentations, press releases, handouts, or conversations, raising the tree awareness of citizens will have a significant positive affect on the Community Forest at large.

C. Public Relations
There are several effective methods available for raising the awareness of citizens in terms of tree care. Many citizens are unaware that there are resources for information regarding proper tree selection, planting, and maintenance. The City will employ the following methods to educate its citizens and its staff.

1. Direct public relations are practiced when any City employee discusses tree care or tree issues with members of the public. All employees who have contact with the public concerning Urban Forest management issues will be trained to answer questions properly.

Staff will carry International Society of Arboriculture handouts describing common tree issues and proper practices that can be easily distributed. Staff will also participate in regional tree related activities.

2. Indirect public relations are no less important than direct public relations and can often reach a larger audience. The City will provide news releases when appropriate, hold Arbor Day celebrations when feasible, provide exhibits in local

DEAND\14100.14001\10298378.8
fairs, and provide educational programs and material to schools. City social media will be the primary platform to disseminate information on urban forestry.

D. Distribution of Education Material
The City will develop and provide education material to be used as handouts, displays, and web- based resources. The City will develop an approach to educating its citizens and provide some of the following education material: flyers, newsletters, fact sheets, brochures, maps, and informational signs. Materials will be developed into infographics, diagrams, and visual representations where applicable to best convey messaging. Thisinformation will be presented to the community on a quarterly basis through social media, mailers, and flyers.

In addition, the City will develop a section dedicated to the Urban Forest Management program on its website, which will include links to maintenance schedules, removal requests, heritage and large native tree nomination forms and protected tree lists, educational materials, contact information and general tree care information.

E. Tree City USA
The City shall endeavor to become a Tree City USA and maintain Tree City USA status. There are many benefits to the community of the Tree City USA designation, including a framework for Community Forest standards, elevating the public image of the City, citizen pride, access to urban forestry related financial assistance and opportunities for good direct public relations.

To qualify as a Tree City USA community, a town or City must meet four standards established by The Arbor Day Foundation and the National Association of State Foresters. These standards were established to ensure that every qualifying community would have a viable citywide tree program:

1. A Tree Board or Department (i.e., Parks and Recreation Commission)

2. A Tree Care Ordinance (i.e., CMC Chapter 12.22)

3. A Community Forestry Program with an Annual Budget of at Least $2 Per Capita

4. An Arbor Day Observance and Proclamation.

DEAND\14100.14001\10298378.8
SECTION 11 URBAN WOOD RECYCLING PROGRAM
A. Applicability
This Section 11 (Urban Wood Recycling Program) shall apply to City Trees and Shared Responsibility Trees, and may apply to Private Trees with the written consent of the owner of the Private Tree.

Urban tree waste shall be used for its greatest environmental benefit. This shall be done by reducing the amount of wood being sent to landfills, resulting in reduced greenhouse gas emissions. Co-environmental benefits include sourcing local raw materials, supporting a local workforce, and creating greater community value products.

B. Tree Pruning and Removal Biomass Utilization Plan

1. Any trees that are removed for reasons such as failure, disease, decline, or other reasons stated within this Management Plan are subject to be repurposed for their highest use. This includes, but is not limited to, being milled into lumber, left in public spaces as natural architecture, wildlife habitat, crafted into usable products such as benches, picnic tables, new construction elements and/or other wood projects.

2. The selection criteria for urban wood shall be made at the discretion of the City Arborist or other designated City staff using current industry standards. a. The City shall consider possible urban wood utilization for trees that are removed. b. The City shall coordinate the proper removal and transportation of eligible logs when feasible.

3. Should wood not be eligible for repurposing into product, trees may be processed into mulch or converted into other biomass products for use in the community (for example, March Mulch Madness).

4. Mulching is one of the most effective ways to improve soil quality and tree health. Organic mulches moderate soil temperatures, reduce water use, stimulate soil microbial activity, and improve soil structure over time. Green waste from tree care operations should be recycled back into the community as much as possible by way of allowing public access to free source wood chips from the City. Mulching provides the following beneficial uses:
a. Prevent soil compaction
b. Prevent erosion
c. Limit evaporation
d. Deter pests
e. Control weeds

DEAND\14100.14001\10298378.8
f. Promote soil aggregation
g. Increase soil organic matter
e. Increase soil nutrients.

5. Mulching with green waste should be considered a long-term method to treat moderately compacted soil within the root zones of trees and woody plants. Fresh or partially composted coarse (greater than ¾” average wood particle size) wood- chip mulch from trees should be preferred when the objective is to improve soil structure.

6. The ignitability of mulch should be considered when placing it in the landscape, and mulch should not be placed against tree trunks. Green waste from tree care operations should be applied and maintained at a depth of 2-4 inches and applied over as much to the root zone as practical. Seasonal refreshing or reapplication of mulch is encouraged when practical.

C. Tree Recycling Plan

1. Trees that are removed are subject to be potentially repurposed for their highest use. This includes, but is not limited to, being milled into lumber, left in public spaces as natural architecture including wildlife habitat or crafted into useable products such as benches, picnic tables, new construction elements and / or other wood crafts/projects.

2. Suggested resources for wood processing can be found at urbansalvagedwoods.com and urbanwoodnetwork.org.

3. The selection criteria for urban wood shall be made at the discretion of the City Arborist.

4. Should wood not be eligible for repurposing into product, trees may be mulched or other biomass products for use in the community.

D. Urban Wood Mitigation Fund

1. If a small or large project requires the removal of a tree with a DBH greater than 35, the project can fund the reutilization of wood from the removed tree(s) for City use. a. Reutilization includes the cost of transportation, milling, and creation of end use product.
b. Prior to the reutilization, the log must be inspected by the City Arborist to ensure that they will be suitable for use.
c. The City will determine an end use that results in a cost no greater than 1% of the total project.

DEAND\14100.14001\10298378.8
E. Species Replacement Plan

1. Tree replacement criteria should include a consideration for end of life uses, including lumber. For trees that are removed, with the potential for urban wood, a replacement tree fromtheReplacement Sustainable Species List(Appendix D) will be considered for replant.

2. It is recommended that these replacement species be selected in collaboration with local experts based upon the unique region and climate.

DEAND\14100.14001\10298378.8

REQUEST FOR CITY COUNCIL ACTION
SUBJECT:

INNOVATION CENTER AT THE CORONA PUBLIC LIBRARY
EXECUTIVE SUMMARY:

This staff report asks the City Council to provide feedback regarding constructing an Innovation Center at the Corona Public Library. The Innovation Center is funded with a $2.5 million grant from the State of California. The Innovation Center will enhance the library by providing a new programmable space for businesses, residents, and youth to access services, events, training, and technology.

RECOMMENDED ACTION:

That the City Council provide feedback on the construction of an Innovation Center at the Corona Public Library.

BACKGROUND & HISTORY:

In 2023, the City of Corona received a $2.5 million grant from the California Governor’s Office of Business and Economic Development (Go-Biz) to develop an Innovation Center.

An Innovation Center is a dedicated space designed to foster creativity, collaboration, and development. These centers provide resources and services to the community, helping businesses, residents, and students to innovate and develop new products or services.

Pursuant to the Grant Agreement, Corona’s Innovation Center will offer business services, events, training, and entrepreneurship development opportunities. It will also serve as a hub for innovation and will emphasize youth as it pertains to career pathways and introduction to STEM industries. Some eligible expenses allowed under this grant include renovations and related expenses, equipment, and furniture. This project supports the City’s Strategic Plan to develop a Strong Economy by supporting local businesses, providing opportunities for new businesses, and ensuring there are opportunities for job seekers.

The City Council appropriated the full amount of this grant to the Corona Innovation Center Capital Improvement Project No. FC-2023-10 at its May 3, 2023 meeting. The total grant amount must be expended by June 30, 2026.

ANALYSIS:

Since receiving the funds, staff explored various locations for the Innovation Center.

During this time, the Corona Public Library began its effort to develop a strategic plan, which included public engagement via surveys, focus groups, and discussions with government leaders. Much of the feedback received during the public engagement process included requests for technology classes and instruction opportunities, access to advanced technological resources (i.e. 3D printers and digital tools), and expanded workforce development opportunities at the library.

Given this input, staff proposes locating the Innovation Center at the Corona Public Library. Doing so provides numerous opportunities for the library, including:
 Enhancing the building by providing $2.5 million in renovations and equipment.  Placing innovation at the City’s hub for knowledge and learning.  Providing new programable spaces for youth, teen, and adult innovation activities.  Introducing the library to a new demographic by offering varied programs aimed at those who may not visit the library for traditional purposes.

Additionally, the integration of the Innovation Center allows the library to be an active part of the Downtown Revitalization Plan, activating all four corners of the historic streets of Main Street and 6th Street.

Following the construction of the Innovation Center, the City will partner with local businesses and schools to offer business development, workforce development, and youth STEM programs to the community. By collaborating with local school and business partners, in tandem with providing passive activities, the Innovation Center will have a steady stream of programming and offerings to the Corona community. Staff is actively engaged with the Corona Norco Unified School District and local community colleges to ensure programming is in place when the Innovation Center is open.

The proposed area in the library for the Innovation Center is in the southeast corner of the main floor. This area is currently occupied with shelving for the adult collection. Staff is working with a design consultant to develop a floor plan for the Innovation Center that

will utilize and optimize space for the center, seating areas, and the adult area. The floor plan will include appropriate space for the current collection and its potential growth.

This action is exempt pursuant to Section 15061(b)(3) of the Guidelines for the California Environmental Quality Act (CEQA), which states that a project is exempt from CEQA if the activity is covered by the commonsense exemption that CEQA applies only to projects that have the potential for causing a significant effect on the environment. Where it can be seen with certainty that there is no possibility that the activity in question may have a significant effect on the environment, the activity is not subject to CEQA. Therefore, no environmental analysis is required.

REQUEST FOR CITY COUNCIL ACTION
SUBJECT:

ORDINANCE AMENDING CHAPTERS 2.35 AND 2.37 AND REPEALING CHAPTER

2.58 OF THE CORONA MUNICIPAL CODE TO MERGE THE PLANNING COMMISSION

AND HOUSING COMMISSION INTO ONE COMMISSION AND TO ESTABLISH TERM

LIMITS FOR HOUSING AUTHORITY TENANTS IF THEY ARE EVER REQUIRED BY

LAW TO BE APPOINTED AS ADDITIONAL COMMISSIONERS AND REPEALING RESOLUTION NO. 2012-024. (APPLICANT: CITY OF CORONA)
EXECUTIVE SUMMARY:

This staff report asks the City Council to approve an ordinance merging the Housing Commission established by Chapter 2.58 of the Corona Municipal Code (CMC) with the Planning Commission under Chapter 2.37 of the CMC. The Housing Commission was established in 2012 after the dissolution of the City’s Redevelopment Agency. The Planning Commission serves as a member of the Housing Commission according to CMC Chapter 2.58 and the request is to merge the responsibilities of both Commissions into CMC Chapter 2.37, which currently governs the Planning Commission. CMC Chapter

2.37 will be amended to reflect the Planning and Housing Commission.

RECOMMENDED ACTION:

That the City Council introduce, by title only, and waive a full reading of consideration of Ordinance No. 3404, first reading of an ordinance amending Chapters 2.35 and 2.37 and repealing Chapter 2.58 of the Corona Municipal Code to merge the Planning Commission and Housing Commission into one Commission and to establish term limits for Housing

Authority tenants if they are ever required by law to be appointed as additional commissioners and repealing resolution No. 12-024.

BACKGROUND & HISTORY:

The Housing Commission was created in 2012 as an advisory body to the Corona Housing Authority. The Corona Housing Authority is the successor agency to the City’s former Redevelopment Agency. The Planning Commission functions as the Planning Agency and is an advisory body to the City Council. The Planning Commission and Housing Commission were established by Chapters 2.37 and 2.58 of the CMC, respectively. The Planning Commission also serves as the Housing Commission according to CMC Chapter 2.58.

Additionally, the Housing Commission requires two tenants of the Housing Authority to be appointed to the commission, if such tenants exist. Since the Housing Authority does not currently manage residential properties with tenants, no tenants are currently appointed to the Housing Commission.

ANALYSIS:

Since the Planning Commission serves as a member of the Housing Commission, Ordinance 3404 will merge both commissions into one under a single ordinance. Chapter

2.37 of the CMC, Planning Commission, will be amended to include the qualifications, terms of office, the organization, and the powers and duties of the Planning and Housing Commission. Chapter 2.37 will also be renamed the Planning and Housing Commission.

Chapter 2.35, Term Limits for Officials Appointed to Certain City Boards and Commissions, will be amended to include the two-year terms for the tenants of the Housing Authority serving on the Planning and Housing Commission. Persons in this capacity are limited to, six successive, two-year terms.

Chapter 2.58, Housing Commission, will be repealed in its entirety. Additionally, Resolution 2012-024 establishing the bylaws for the Housing Commission will be repealed in its entirety.

FINANCIAL IMPACT:

The adoption of this Ordinance will not have a financial impact on the General Fund.

ENVIRONMENTAL ANALYSIS:

This action is exempt pursuant to Section 15061(b)(3) of the Guidelines for the California Environmental Quality Act (CEQA), which states that a project is exempt from CEQA if the activity is covered by the commonsense exemption that CEQA applies only to projects that have the potential for causing a significant effect on the environment. Where it can be seen with certainty that there is no possibility that the activity in question may have a significant effect on the environment, the activity is not subject to CEQA. This action amends the text of the Corona Municipal Code to combine the Planning Commission and Housing Commission into one commission and will not have an impact on the environment.

WHEREAS, pursuant to Health and Safety Code section 34290, if the City Council declares itself to be the Housing Authority's board of commissioners and if the Housing Authority has tenants the City Council must also appoint two of the Housing Authority's tenants to serve as members of the Housing Authority board; and
WHEREAS, alternatively, pursuant to Health and Safety Code section 34290, the City Council can create a housing commission by ordinance pursuant to Health and Safety Code section 34291 to review and make recommendations to the Housing Authority and appoint tenant commissioners to serve on the housing commission; and
WHEREAS, Health and Safety Code section 34272 provides that commissioners may be officers or employees of the City, or members, commissioners, or employees of any other agency created for the community, provided such officers or employees do not exercise powers or duties that may conflict with the exercise of the independent judgment required to carry out the Housing Authority purposes; and

WHEREAS, as authorized by Health and Safety Code section 34290, the City Council enacted CMC Chapter 2.58 to establish the Housing Commission, for the purpose of reviewing and making recommendations to the Housing Authority on all matters to come before the Housing Authority; and

2.37, along with two additional members to be appointed by the City Council if the Housing Authority has tenants (“Tenant Commissioners”); and
WHEREAS, since the Housing Authority does not currently have any tenants, there are no current Tenant Commissioners, and they will be appointed at such time that the Housing Authority has tenants; and

WHEREAS, the City Council desires to repeal Resolution No. 2012-024 because the resolution adopted pursuant to CMC Section 2.37.035 will now govern the rules and procedures for the conduct of the Planning and Housing Commission.
