Item No. 5.
CITY COUNCIL AGENDA – MARCH 1, 2022
SUBJECT: Public Hearing for the Review and Adoption of the 2020 Urban Water Management Plan
SOURCE: Public Works
COMMENT: The Urban Water Management Plan (UWMP) is a requirement of the Urban Water Management Planning Act (UWMPA) (Division 6, Part 2.6 of the California Water Code (CWC) §10610-10656). The UWMP must be submitted to the Department of Water Resources (DWR). The submittal is a requirement of the UWMPA, including the most current amendments that have been made.
The UWMPA applies to urban water suppliers with 3,000 or more connections being served or supplying more than 3,000 acre-feet (AF) of water annually; the City serves more than 17,000 connections and annually supplies more than 10,000 AF of water.
UWMPs are required of the state’s urban water suppliers in an effort to assist with resource planning and to ensure adequate water supplies are available for future use. A secondary purpose of the UWMP is to provide for a plan or series of plans during water drought situations. This plan was prepared according to the requirements of the CWC, UWMPA, and the UWMP 2020 Guidebook.
The 2020 UWMP calculates the city’s average water use in gallons per capita per day (GPCD). The GPCD is used to form a baseline across a ten-year period; 2001 to 2010. The City’s ten-year baseline GPCD is 195 GPCD. The City’s 2020 GPCD target of 179 GPCD is based on the hydrologic region target for the Tulare Lake region. The midpoint between the baseline and the 2020 target is the 2015 interim target of 187 GPCD. The DWR Population Tool was used to calculate the City’s Service Area Population in determining the City’s 2020 compliance year GPCD of 133 GPCD. The City met the 2020 target of 179 GPCD in the year 2020 with an actual per capita water use of 133 GPCD. These efforts were achieved through community conservation and operational efficiencies. Staff’s recommendation is to conduct the Public Hearing and receive public comment prior to the City Council's adoption of the 2020 UWMP.
RECOMMENDATION: That City Council:
1. Conduct a Public Hearing and receive comments on the City's 2020 Urban Water Management Plan;
2. Direct staff to incorporate comments, where appropriate, Item No. 5.
subject to no substantive changes;
3. Adopt the draft Resolution adopting the City's 2020 Urban Water Management Plan;
4. Submit the 2020 Urban Water Management Plan to the
Department of Water Resources, the California State
Library, and Tulare County; and
5. Make the 2020 Urban Water Management Plan available
to the public for review within thirty (30) days after filing a copy of the plan with the Department of Water
Resources.

INTRODUCTION AND LAY DESCRIPTION
1.1 Lay Description
The City of Porterville (City) 2020 Urban Water Management Plan (UWMP) provides the City with a reliable water supply management plan to describe their past, present, and future water system supply, and demand performance. The 2020 UWMP presents a thorough understanding of the City’s existing system demand and supply sources and includes baseline supply and demand conditions to better prepare the City to strategically manage future environmental challenges. These challenges can include, but certainly are not limited to climate change, decrease in water supplies, natural hazards, and water quality variability. This plan also considers future planning preparation for changes in land-use, population growth, infrastructure developments, and government regulations. This document serves to be a general synopsis of the City’s water system and supply sources and to consider its system characteristics given both environmental variability and the ever-changing dynamic of the City.
1.2 Background and Purpose
The California Water Code (CWC) requires urban water suppliers within the state to prepare and adopt UWMPs for submission to the California Department of Water Resources (DWR). The UWMP, which must be filed every five years, must satisfy the requirements of the Urban Water Management Planning Act (UWMPA) of 1983, including amendments that have been made to the Act. The UWMPA requires urban water suppliers servicing 3,000 or more connections, or supplying more than 3,000 acre-feet (ac-ft) of water annually, to prepare a UWMP.
The purpose of the UWMP is to maintain efficient use of urban water supplies, continueto promote conservation programs and policies, ensure that sufficient water supplies are available for future beneficial use, and provide a mechanism for response during water drought conditions. This document, which was prepared in compliance with the CWC, and as set forth in the 2020 Urban Water Management Plan Guidebook for Urban Water Suppliers (March 2021) established by the DWR, constitutes the City 2020 UWMP.
This 2020 UWMP was prepared in compliance with the UWMPA (CWC §10610 et seq.) and the Water Conservation Bill of 2009 (Senate Bill [SB] X7-7) by Carollo Engineers, Inc. (Carollo).
Contact information for the City and Carollo Engineers is included in the Contact Sheet provided at the beginning of this document.
The City recognizes the importance of maintaining a high-quality reliable water supply. Although water is a renewable resource, it is limited. A long-term reliable supply of water is essential to protect the local and state economy. The main focus for the City is to provide high quality water, maximize the efficient use of water, and promote conservation.
CITY OF PORTERVILLE | 2020 URBAN WATER MANAGEMENT PLAN| CH 1 INTRODUCTION AND LAY DESCRIPTION 1-2 | JANUARY 2022 | DRAFT FINAL
1.2.1 Previous Urban Water Management Plan
The City previously prepared an UWMP in 2015, which was approved and adopted on February 20, 2018. Following adoption, the 2015 UWMP was submitted to and formally approved by the DWR. The 2020 UWMP report serves as an update to the 2015 UWMP and pulls extensively from that report. References used in the writing of this report as well as the 2015 UWMP can be found in Appendix C.
1.3 Urban Water Management Planning and the California Water Code The CWC sections applicable to UWMPs are summarized in the sections below.
1.3.1 Urban Water Management Planning Act
In 1983, State Assembly Bill (AB) 797 modified the CWC Division 6 by creating the UWMPA.
Several amendments to the original UWMPA, which were introduced since 1983, have increased the data requirements and planning elements to be included in the UWMPs.
Initial amendments to the UWMPA required that total projected water use be compared to water supply sources over the next 20 years, in 5-year increments. DWR guidelines also suggest projecting through a 25-year planning horizon to maintain a 20-year timeframe until the next UWMP update has been completed.
Other amendments require that UWMPs include provisions for recycled water use, demand management measures (DMMs), and a water shortage contingency plan (WSCP). The UWMPA requires a WSCP which meets the specifications set forth therein. Recycled water was added in the reporting requirements for water usage and figures prominently in the requirements for evaluation of alternative water supplies when future projections predict the need for additional water supplies. Each urban water purveyor must coordinate the preparation of the WSCP with other urban water purveyors in the area, to the extent practicable. Water suppliers must also describe their water DMMs that are being implemented or are scheduled for implementation.
In addition to the UWMPA and its amendments, there are several other regulations that are related to the content of the UWMP. In summary, the key relevant regulations are:
• AB 1420: Requires implementation of DMMs/Best Management Practices (BMP) and meeting the 20-by-2020 targets to qualify for water management grants or loans. • AB 1420: Requires a plan to quantify and report on distribution system water loss. • AB 1420: Provides for water use projections to display and account for the water savings estimated to result from adopted codes, standards, ordinances, or transportation and land use plans, when that information is available and applicable to an urban water supplier.
• AB 1465: Requires water suppliers to describe opportunities related to recycled water use and stormwater recapture to offset potable water use. • Amendments SB 610 (Costa, 2001) and AB 901 (Daucher, 2001): Require counties and cities to consider information relating to the availability of water to supply new large developments by mandating the preparation of further water supply planning (Daucher) and Water Supply Assessments (Costa).
• SB 1087: Requires water suppliers to report single-family residential (SFR) and multifamily residential (MFR) projected water use for lower income areas separately.
CH 1 INTRODUCTION AND LAY DESCRIPTION | 2020 URBAN WATER MANAGEMENT PLAN | CITY OF PORTERVILLE DRAFT FINAL | JANUARY 2022 | 1-3
• Amendment SB 318 (Alpert, 2004): Requires the UWMP to describe the opportunities for development of desalinated water, including but not limited to, ocean water, brackish water, and groundwater, as long-term supply.
• AB 105 (Wiggins, 2004): Requires urban water suppliers to submit their UWMPs to the California State Library.
• SB X7-7: Requires development and use of new methodologies for reporting population growth estimates, base per capita use, and water conservation. An agency can choose from four methods to establish their interim (2015) and year 2020 water conservation targets.
• AB 2067:Requires water suppliers to provide narratives of water DMMs. • SB 1036: Provides for an urban water supplier to include certain energy-related information, including, but not limited to, and estimate of the amount of energy used to extract or divert water supplies.
• AB 2409: Requires urban water suppliers to analyze and define water features that are artificially supplied with water, including ponds, lakes, waterfalls, and fountains separately from swimming pools and spas.
1.3.2 New Requirements to the Water Code since the 2015 UWMPs The major new requirements to the CWC since 2015 UWMPs are summarized in Table 1-1.
Table 1.1 Applicable Changes to the Water Codes Since 2015 UWMPs Topic Summary
Five Consecutive Dry-Year
Water Reliability
Assessment
The Legislature modified the dry-year water reliability planning from a “multiyear” time period to a “drought lasting five consecutive water years” designation.
Drought Risk Assessment
The Drought Risk Assessment (DRA) requires a Supplier to assess water supply reliability over a five-year period from 2021 to 2025 that examines water supplies, water uses, and the resulting water supply reliability under a reasonable prediction for five consecutive dry years.
Seismic Risk Requires Suppliers to specifically address seismic risk to various water system facilities and to have a mitigation plan.
Water Shortage
Contingency Plan
Supplier must provide a standalone document that provides an action plan for a drought or catastrophic water supply shortage. The WSCP includes requirements that are more prescriptive than previous UWMPs.
Groundwater Supplies
Coordination
Water Code now requires Suppliers’ 2020 UWMPs to be consistent with Groundwater Sustainability Plans, in areas where those plans have been completed by Groundwater Sustainability Agencies.
Lay Description
Suppliers to include a lay description of the fundamental determinations of the UWMP, especially regarding water service reliability, challenges ahead, and strategies for managing reliability risks. This section of the UWMP could be viewed as a go-to synopsis for new staff, new governing members, customers, and the media, and it can ensure a consistent representation of the Supplier’s detailed analysis.

PLAN PREPARATION
This section includes specific information on how the UWMP was developed, including efforts in coordination and outreach.
2.1 Basis for Plan Preparation
CWC 10617 requires that urban water suppliers with 3,000 or more service connections or supplying 3,000 or more ac-ft of water per year prepare an UWMP every five years. 10617 “Urban water supplier” means a supplier, either publicly, or privately owned, providing water for municipal purposes either directly or indirectly to more than 3,000 customers or supplying more than 3,000 acre-feet of water annually. An urban water supplier includes a supplier or contractor for water, regardless of the basis of right, which distributes or sells for ultimate resale to customers. This part applies only to water supplied from public water systems…
2.1.1 Public Water Systems
California Health and Safety Code 116275 (h)“Public Water System” means a system for the provision of water for human consumption through pipes or other constructed conveyances that has 15 or more service connections or regularly serves at least 25 individuals daily at least 60 days out of the year.
To demonstrate the basis of reporting, the Public Water Systems services by the City are listed in Table 2.1. As listed in Table 2.1, the City of Porterville served 1 public water system with a total of 17,063 connections and supplied a total of 3,647 million gallon (MG) (11,192 acre-feet per year [AFY]) in year 2020.

2.4.3 Notice to Cities and Counties
CWC 10621 (b) requires that agencies notify cities and counties to which they serve water that the City’sUWMP is being updated and reviewed.
10621(b) Every urban water supplier required to prepare a plan pursuant to this part shall, at least 60 days before the public hearing on the plan required by Section 10642, notify a city or county within which the supplier provides water supplies that the urban water supplier will be reviewing the plan and considering amendments or changes to the plan.
The City of Porterville only provides water within their urban development boundary (UDB).
Even though the City does not provide water supply to other cities, counties, or districts, outside the water service area the City has provided formal written notification to the list of agencies in Table 2.5 that the City’sUWMP was being updated. In accordance with the UWMPA, this notification was provided at least 60 days prior to the public hearing of the plan. Electronic copies of the final UWMP will be provided to the parties notified no later than 30 days after its submission to DWR. Appendix D contains copies of outreach documents.
Notices were published informing interested parties that the draft 2020 UWMP was available for review. Pursuant to California Code Section 6066, a notification of the time and place of the public hearing was published in the local newspaper on February 1st, 2022 and February 8th, 2022.
A notice was also posted on City’s website. Copies of these notifications are included in Appendix D.
The Final Draft 2020 UWMP was presented to the Porterville City Council as a discussion item on February 15th, 2022 for a public hearing followed by adoption by resolution. This hearing provided an opportunity for the City’s customers, residents, and employees to learn and ask questions about the current and future water supply of Porterville.

CH 3 SYSTEM DESCRIPTION | 2020 URBAN WATER MANAGEMENT PLAN | CITY OF PORTERVILLE DRAFT FINAL | JANUARY 2022 | 3-1
Chapter 3
SYSTEM DESCRIPTION
The UWMPA requires that the UWMP include a thorough description of the water system, service area, and various aspects of the area served including climate, population, and other demographic factors.
10631. (a) Describe the service area of the supplier, including current and projected population, climate, and other demographic factors affecting the supplier's water management planning.
The projected population estimates shall be based upon data from the state, regional, or local service agency population projections within the service area of the urban water supplier and shall be in five-year increments to 20 years or as far as data is available.
3.1 General Description
The City of Porterville is located in central California on the east side of the San Joaquin Valley.
The City is adjacent to the Sequoia National Forest and the Sierra Nevada Foothills in Tulare County. Porterville is approximately 70 miles southeast of the City of Fresno and 50 miles north of the City of Bakersfield. Figure 3-1 depicts the City of Porterville’s Regional Location Map. The City is bisected by the Tule River which is sourced by precipitation from the Sierra Nevada Mountains. Operation of the Tule River is regulated by the U.S. Army Corps of Engineers Success Dam located approximately five miles east of the City. During wet years, floodwaters are controlled by Success Dam. The Central Valley Project’s (CVP) Friant Kern Canal conveyance facility passes the City on its western boundary. This canal is sourced from the San Joaquin River Watershed and is managed by the Friant Water Authority. The City does not receive surface water from the Canal. The City limits encompass the Porterville Municipal Airport, the Sports Complex, and various agricultural land for treated wastewater management to the southwest of the City proper. The city uses recycled water as a means of treated wastewater effluent disposal for unrestricted agricultural irrigation to select parcels near the airport, see section 6.6 in Chapter 6. This area is also served by the City water system. Additionally, the Porterville Developmental Center or also known as the State Hospital directly east of the City is included in the City limits, however, receives its water supply from on-site wells. The Developmental Center receives sewer service from the City.
The City is a part of the Eastern Tule Groundwater Sustainability Agency (GSA) which also includes, Porterville Irrigation District, Saucelito Irrigation District, Teapot Dome Water District, Vandalia Water District, Terra Bella Irrigation District, Kern-Tulare Water District, and Tulare County.
East Porterville is an unincorporated section of the City that historically has only partly been serviced by the City’s public water distributions system. Recent drought conditions have led to an emergency water shortage for East Porterville residents resulting in reduced groundwater elevation causing wells to run dry. The City and DWR have implemented a program to connect parts of East Porterville residents to the City’s water distribution system over the span of a few years. The City began this program in 2016 and connected approximately 725 connections CITY OF PORTERVILLE | 2020 URBAN WATER MANAGEMENT PLAN| CH 3 SYSTEM DESCRIPTION 3-2 | JANUARY 2022 | DRAFT FINAL
between 2016 and 2020.East Porterville is currently within the City’s 2030 General Plan UDB and Sanitary Sewer Service is still managed by the Porter Vista Public Utilities District, but is treated at the City’s waste water treatment facility.
3.1.1 Description of Transmission, Treatment, and Distribution Facilities The City of Porterville drinking water supply is solely from groundwater wells. As mentioned, the City does not receive any surface water from the Tule River or the Friant Kern Canal. The City does not participate in any surface drinking water exchanges with the local water agencies included in the Eastern Tule GSA. The City’s groundwater supply is extracted using 36 active wells scattered throughout the water service area that pump directly into the water distribution system, however a few of these wells are on standby for high demands. Extracted groundwater is chlorinated at the wellheads to provide disinfectant residual in the distribution system. In total, Porterville’s water service area encompasses 11,904 acres, or approximately 18.6 square miles.
The City has approximately 276 miles of water distribution pipeline ranging from sizes 4- to 16-inches in diameter. Figure 3.2 shows the City’s water service area, wells, and water transmission main layout.
3.2 Service Area Climate
10631(a). A plan shall… Describe the service area of the supplier, including … climate… 10630.It is the intention of the Legislature, in enacting this part, to permit levels of water management planning… while accounting for impacts of climate change.
The City’s service area climate is a semi-arid, Mediterranean environment with cold winters, warm summers, and moderate rainfall. The City experiences generally dry weather conditions throughout the year with rain occurring through the months of November through April. Average monthly evapotranspiration (ETo) rates, rainfall, and temperature are summarized in Table 3.1.

CITY OF PORTERVILLE | 2020 URBAN WATER MANAGEMENT PLAN| CH 3 SYSTEM DESCRIPTION 3-6 | JANUARY 2022 | DRAFT FINAL
-This Page Intentionally Left Blank-
CH 3 SYSTEM DESCRIPTION | 2020 URBAN WATER MANAGEMENT PLAN | CITY OF PORTERVILLE DRAFT FINAL | JANUARY 2022 | 3-7
As shown in Table 3.1, the City’s service area's average monthly temperature ranges from about 47 to 78°F. Total annual values of ETo and precipitation are 53.37 inches and 11.62 inches, respectively. Records show that the average monthly precipitation ranges from 0 to 2 inches with most of the precipitation typically occurring from November through April.
3.3 Climate Change
Climate change in California has the potential to increase temperature, reduce snowfall and extend periods of severe drought. Porterville is located in the Tulare Lake Hydrologic Region which encompasses roughly 17,000 square miles in the southern San Joaquin Valley. In this region, the following climate effects are likely expected in the future:
• Crops affected by reduced winter chill hours, increasing extreme heat days, and increasing evapotranspiration therefore requiring more irrigation. • Loss of snowpack reduces reliability of surface water and replenishment of local supplies, resulting in greater demand for groundwater.
• Higher likelihood of extreme wet and dry years.
• Increased frequency of flooding in low-lying areas.
• Average annual maximum temperatures likely to increase 5 to 9 degrees F by the year 2100.
These climate change affects all have potential to impact the water supply of the City. The groundwater aquifers in the Central Valley are generally recharged through a combination of precipitation through rainfall and percolation through the various rivers and canals sourced from the Sierra snow melt. With a decrease in groundwater recharge and increase in average temperatures and overall demand, a perfect storm of low supply and increased use limits the availability of groundwater for all users in the Valley.
The City of Porterville is completely reliant upon groundwater for its drinking water supply. The City is surrounded by agricultural land varying in citrus, vegetable, nut, and grain crops which receive water from either an irrigation district supplied from the Friant-Kern Canal or a private agricultural well. Groundwater levels have dropped significantly over the last drought period as outlined in the Eastern Tule Groundwater Sustainability Plan (ETGSP). With a significant reduction in surface water allocations most farmers and surrounding communities were left with no choice but to utilize the groundwater supply for agricultural use.
Drought conditions initially cause increase in demand with increase temperatures and reduced precipitation. The diurnal pattern of demand over an average year peaks in the hotter months for landscape irrigation, recreation, and agricultural uses. Over-pumping leaves the City’s groundwater supply and pumping effectiveness quite vulnerable to significant reductions in groundwater elevations from a rise in demands. The City does not have an alternative supply of water therefore drastic reduction in groundwater elevation creates an extremely vulnerable condition which puts the City at risk. Effects of drought have already occurred nearby to the community of East Porterville which experienced emergency water shortage issues during the last major drought event between 2013 and 2017 and required State intervention. The overall hydrologic dynamic of the City and surrounding area’s drinking water supply are exposed to the effects and changing conditions set upon by climate change.
CITY OF PORTERVILLE | 2020 URBAN WATER MANAGEMENT PLAN| CH 3 SYSTEM DESCRIPTION The following chapters will present a more detailed approach on the City’s efforts to develop a more reliable and diverse source of water and to address excessive groundwater pumping to eliminate over drafting conditions in the future:
• Chapter 4: Customer Water Use
• Chapter 5: Conservation Target Compliance
• Chapter 6: Water Supply Characterization
3.4 Service Area Population and Demographics
10631(a). Describe the service area of the supplier, including current and projected population …The projected population estimates shall be based upon data from the state, regional, or local service agency population projections within the service area of the urban water supplier and shall be in five-year increments to 20 years or as far as data is available.
This section summarizes historical, current, and projected population trends in the Porterville.
Population projections are essential to theplanning process and form the basis for most planning decisions, yet projecting future growth is far from an exact science given thecomplex set of variables that can affect the rate of growth. Typically, projections are developed by taking past patterns and combining them with assumptions to obtain an estimate of future growth rates. These projections serve to provide the City insight on the type and quantity of future growth as well as guidance regarding futureplanning activities; therefore, such planning activities can only be as effective as the ability to anticipate population growth. The general Porterville water service population consists mainly of full-time residents and has a very small transient population that commute into the City service area for work or travel.
3.4.1 Service Area Population
The water service population from 2001 to 2010 was taken from theCity’s 2015UWMP. At the time, the growth rate was calculated at approximately 2.5 percent. Historical population growth rates have been approximately 2.2 percent on average which is shown in Figure 3-3. The water service populations for the 2020 UWMPwas calculated using an acceptable modification of the DWR population. The DWR population tool resulted in an abnormally high persons per connection of 4.98. To reflect current population growth, the 2010 persons per connection of
4.39 was used as an acceptable modification per thepopulation tool guidelines. The resulting water service population, shown in Figure 3.3, is estimated at 74,907. The Population Toolresults are included in Appendix K. Table 3.2 shows the current and projected water service population for the City.

3.4.2 Other Social, Economic, and Demographic Factors
10631. Describe the service area of the supplier, including… other social, economic and demographic factors affecting the supplier’s water management planning.
Porterville is located in a rural area that depends on an independent water management strategy that solely services the City. DWR defines disadvantage communities (DAC) as regions whose annual median household income (MHI) is less than 80 percent of the Statewide annual MHI. The City of Porterville is mostly within the California’s DAC boundary as shown in Figure 3-4. Most of the City’s water service population identifies to be within a DAC. The current Statewide MHI is $71,228 and per 2019 census data, the median household income for Porterville residents is $43,823.
Implemented in 2020 as a result of the COVID-19 pandemic, California legislation was passed that requires the City to provide a payment plan for outstanding utility bill balances since the deferral of water shutoff as a result of non-payment was not allowed during the pandemic.
Otherwise, the City does not provide utility bill payment assistance. 74,907

3.5 Land Uses within Service Area
10631(a). The description shall include the current and projected land uses within the existing or anticipated service area affecting the supplier’s water management planning. Urban water suppliers shall coordinate with local or regional land use authorities to determine the most appropriate land use information, including, where appropriate, land use information obtained from local or regional land use authorities…
The City of Porterville Urban Development Boundary (UDB) is defined in its 2030 General Plan which has a total area of approximately 17,183 acres. The City service area falls within the City limits and few areas outside of the limits, such as the East Porterville area, which is still within the UDB. The UDB extends from Lake Success to the Friant Kern Canal as its western border and from Avenue 182 to the airport as its north and south limits. Land use information presented in this UWMP is based on the City’s 2030 General Plan.
3.5.1 Land Use and Existing Service Area
Figure 3.5 shows the City’s existing land use map. Table 3.3 provides a summary, by land use, of the amount of developed and underdeveloped land within the existing service area.
As shown in Table 3.3, there are approximately 6,482 acres of developed and underdeveloped land within the service area (excluding right-of –ways such as streets, highways, and railroads).
Within the service area, 3,782 acres (58 percent) are classified as residential, 608 acres (9 percent) are classified as commercial, and 399 acres (6 percent) are associated with Industrial.
The remaining mixed use and others make up the remaining 1,692 acres (26 percent). The East Porterville land use area shown in Figure 3.3 is generally single family residential with a few commercial and public intuitional classified parcels throughout. This area comprises of approximately 1,704 total acres.

Chapter 4
CUSTOMER WATER USE
The UWMPA requires that the UWMP identify the quantity of water supplied to the agency’s customers including a breakdown by user classification. This section describes the water system demands and water demand projections.
4.1 Non-Potable Versus Potable Water Use
This chapter covers potable and raw water demand. Recycled water is addressed comprehensively in Chapter 6.4.
4.2 Past, Current, and Projected Water Use By Sector
10631(d). (1) For an urban retail water supplier, quantify, to the extent records are available, past, and current water use, over the same five-year increments described in subdivision (a), and projected water use, based upon information developed pursuant to subdivision (a), identifying the uses among water use sectors, including, but not necessarily limited to, all of the following… (2). The water use projections shall be in the same five-year increments described in subdivision (a).
(4)(A) Water use projections, where available, shall display and account for the water savings estimated to result from adopted codes, standards, ordinances, or transportation and land use plans identified by the urban water supplier, as applicable to the service area. (B) To the extent that an urban water supplier reports the information described in subparagraph (A), an urban water supplier shall do both of the following: (i) Provide citations of the various codes, standards, ordinances, or transportation and land use plans utilized in making the projections. (ii) Indicate the extent that the water use projections consider savings from codes, standards, ordinances, or transportation and land use plans. Water use projections that do not account for these water savings shall be noted of that fact.
Water demands served by the City are primarily residential (includes SFR and MFR), commercial, industrial, and institutional (CII), and landscape irrigation. Of the City’s 17,063 connections, 16,814 of them are metered. The City classifies meters (2020) into the following categories:
• Single Family Residential.
• Multi-Family Residential.
• Commercial/Institutional.
• Industrial.
• Landscape Irrigation.
• Other.
• Agricultural Irrigation.
CITY OF PORTERVILLE | 2020 URBAN WATER MANAGEMENT PLAN | CH 4 CUSTOMER WATER USE Ͱ‐ͮ | JANUARY 2022 | DRAFT FINAL
The actual demands for potable and non‐potable water are presented in Table Ͱ.ͭ for the ͮͬͮͬ calendar year. Conservation efforts between ͮͬͭͱ and ͮͬͮͬ indicate that the City is using less water than originally anticipated in the ͮͬͭͱ UWMP. The ͮͬͮͬ projections in the ͮͬͭͱ UWMP, show an anticipated potable water demand of Ͱ,ʹͱͳ MG. The ͮͬͮͬ actual use, shown in Table Ͱ.ͭ, is ͭ,ͮͭͬ MG (ͯ,ͳͭͯ AF) or ͮͱ percent less than the ͮͬͮͬ projected demand. The combination of continued below average and inconsistent precipitation, general water conservation mindset, and metering has decreased typical potable water consumption to approximately ͭͯͬ gallons per capita per day (gpcd). Moving forward, the City’s per capita water usage is expected to increase with population growth and favorable hydrologic conditions. The City utilizes the ͭͳ͵ gpcd as a conservative approach for planning purposes in their water, sewer, storm drain integrated master plan (IMP) and other studies.

Table Ͱ.ͮ contains the projected potable water demands from ͮͬͮͱ through ͮͬͰͬ. The demand projections are based on the growth projections from the City’s IMP. From the IMP, it was determined the methodology for future water demand projections includes a combination of projection population, per capita demand rates, water demand factors (by land use), and land use designations. The future demands, the baseline per capita demand, was applied to the projected population to estimate infill and new development. Additionally, for undeveloped land, the future demands were calculated by applying water demand factors to the designated land use acreage within the UDB. Table Ͱ.ͮ are only general estimates of projected use and may vary significantly based on future development and water conservation measures taken by each customer sector.

The City’s total water demands for potable and recycled water are based on the figures presented in Table 4.1, Table 4.2, and Table 6.4. These demands are summarized in Table 4.3. As discussed in chapter 3, currently, the City uses recycled water as a means of treated wastewater effluent disposal for restricted agricultural irrigation. Within the next five years, the City plans to provide recycled water for unrestricted agricultural irrigation to nearby irrigation districts for beneficial use as described in Chapter 6.

As shown in Table 4.4 and reported in the AWWA water audit (Appendix E), the City had approximately 1,035.5 AFY of water loss in their latest 2020 report. The system losses for the five preceding years were:
• 2016 – 951.8 AFY of water loss.
• 2017 – 1082.5 AFY of water loss.
• 2018 – 1242.2 AFY of water loss.
• 2019 – 1123.8 AFY of water loss.
• 2020 – 1035.5 AFY of water loss.
The average total Water loss between 2016 and 2020 is approximately 1004 AF or 327 MG.
4.4 Estimating Future Water Savings
"Passive" savings are water savings from codes, standards, ordinances, or transportation and land use plans. As shown in Table 4.5, future water savings are not included in the total water use projections (Table 4.2) and lower income household demand projections are included in the total water use projections (Table 4.2 and Table 4.3).

CH 4 CUSTOMER WATER USE| 2020 URBAN WATER MANAGEMENT PLAN | CITY OF PORTERVILLE DRAFT FINAL | JANUARY 2022 | 4-5
10631.1(a). The water use projections required by Section 10631 shall include projected water use for single-family and multifamily residential housing needed for lower income households, as defined in Section 50079.5 of the Health and Safety Code, as identified in the housing element of any city, county, or city and county in the service area of the supplier.
The 2015 UWMP calculated water use for low-income housing based on the City’s 2015 Housing Element report referenced in the 2030 General Plan. The low-income forecasted demands were based on a usage of 3.39 persons per occupied household. Since then, 2020 Census data report that the City of Porterville has a 27.5-percent of person to be in poverty. DWR Drought and Water Shortage Risk for self-supplied communities identify Porterville to have a 28.4 percent of persons in the area living at or below federal poverty standards. Using the IMP planning level per capita demand and the 2020 SB7x7 Target demand of 179 gpcd, the total estimated 2025 to 2040 projected water use for lower income households is shown in Table 4.6. Percent of persons in poverty were averaged from historical data from Tulare County Census data.

4.6 Climate Change Considerations
Recent affects in climate change have drastically altered the water consumption standards and behaviors of the entire state of California. The Central San Joaquin Valley in particular has been significantly affected by the most recent California drought and continues to face abnormally warm seasons, severe weather changes, reduced snowpack, and less frequent rainfall events.
Coupled with population growth, the increased demand and decrease supply poses a problem that can potentially impact a City’s growth and increase infrastructure vulnerabilities and risks.
As stated in Section 3.3, Groundwater levels have dropped significantly over the last drought period as outlined in the ETGSP. With a significant reduction in surface water allocations most farmers and surrounding communities were left with no choice but to utilize the groundwater supply for agricultural use. The City has been successful at facing the adversity of climate change by reducing potable water consumption and adaptation strategies (water supply diversification), actively participating in groundwater recharge efforts through treated wastewater effluent management, surface water allocations, and investigating the feasibility of diversifying and expanding their drinking water supply.
Since approximately 2008,the City’s per capita demand has gradually decreased with significant reductions beginning in 2013.Demands in 2013 peaked at 179 gpcd and have reduced to 130 gpcd on average in 2015 and have remained consistent through 2020.The City of Porterville’s 2015 UWMP shows a projected total gross water use in 2020 to be 4,857 MG in Table 4.2. The City’s 2030 general plan aims to reduce the groundwater pumping to match the safe yield of the groundwater basin. Similarly, as part of the Eastern Tule GSA, the City plans to reduce groundwater usage by diversifying their supply portfolio as well as implement additional groundwater recharge in the future. Table 4.3 in this 2020 UWMP shows a total gross water use potable water use to be 3,647 MG, which is a net change of 1,210 MG when compared to the Projected 2020 gross water use of 4,857 MG. The projected total gross water use in comparison to the 2015 UWMP was adjusted based on the 2020 actual value. The significant drop in total CITY OF PORTERVILLE | 2020 URBAN WATER MANAGEMENT PLAN| CH 4 CUSTOMER WATER USE 4-6 | JANUARY 2022 | DRAFT FINAL
gross projections takes into consideration that the standard practice of domestic water consumption and the implementation of conservation efforts set by the City. Water use reduction efforts throughout the city has promoted a conservation culture which in turn has decreased total usage over time. Available rebates for high efficiency plumbing, installation of water meters on new and existing services, water waste audits, landscape rebates and selection, and a more conscientious effort by citizens has proved to reduce total usage and ultimately decrease projections over the next 20 years.
Climate change has already impacted various communities nearby and the City of Porterville itself. Porterville has taken many steps in preparation to progress forward in reducing current and future climate change impacts to their water system through conservation strategies and by having the foresight to augment their water supply portfolio. The City continues to investigate means to reduce water consumption and loss, improve infrastructure, and create the ability to both augment and diversify their existing water supply.
CH 5 CONSERVATION TARGET COMPLIANCE | 2020 URBAN WATER MANAGEMENT PLAN| CITY OF PORTERVILLE DRAFT FINAL | JANUARY 2022 | 5-1
Chapter 5
CONSERVATION TARGET COMPLIANCE
The UWMPA requires that the UWMP identify the baseline water demand, urban water use target, and interim urban water use target for the City. In the 2015 UWMP these water use targets were determined per the DWR Methodologies. The daily per capita water use, expressed in gpcd, is the total water use within the service area divided by the population. These targets are necessary to judge compliance with the 2020 use reductions set forth in the Water Conservation Bill of 2009 (SB X7-7).
The purpose of this section in the 2020 UWMP is to determine whether the City has met the 20 percent conservation mandate. All SB X7-7 forms are included in Appendix F.
5.1 2015 UWMP Baseline and Targets
A supplier may update the baseline and target water use if there were changes to their distribution area. Porterville’s distribution area has not changed since 2015. Therefore, the baseline and target gpcd values from the 2015 UWMP are utilized in this UWMP to determine compliance with the 2020 target. In the 2015 UWMP, a 10-year baseline and a 5-year baseline were calculated to establish the minimum criteria for the Porterville’s water use reduction targets. The 2015 UWMP identifies that the 10-year baseline range (2001 to 2010), and 5-year baseline range (2003 to 2007) are 195 and 199 gpcd, respectively. These tables are included in Table 5 of the SB X7-7 Verification Forms of the 2015 UWMP (Appendix C).The City’s water use target for 2020 is 179 gpcd, see section 5.1.5.3.
5.2 Service Area Population
10608.20. (e) An urban retail water supplier shall include in its urban water management plan due in 2010… the baseline per capita water use,…along with the bases for determining those estimates, including references to supporting data.
(f) When calculating per capita values for the purposes ofthis chapter, an urban retail water supplier shall determine population using federal, state, and local population reports and projections.
10644. (a)(2) The plan… shall include any standardized forms, tables or displays specified by the department.
The 2020 service area population was provided by the DWR Population Tool. This population is shown in table 3-1 and was used to calculate the 2020 target per capita demand. The population in the 2015 UWMP to develop the baseline target was determined using the DWR Population tool as shown in Table 2 of the SB X7-7 Verification Forms. The 2020 service area population is reported in Table 3 of the SB X7-7 Verification Forms.

5.3 Gross Water Use
ͭͬͲͬʹ.ͭͮ (g) "Gross Water Use" means the total volume of water, whether treated or untreated, entering the distribution system of an urban retail water supplier, excluding all of the following:
(ͭ) Recycled water that is delivered within the service area of an urban retail water supplier or its urban wholesale water supplier
(ͮ) The net volume of water that the urban retail water supplier places into long term storage
(ͯ) The volume of water the urban retail water supplier conveys for use by another urban water supplier
(Ͱ) The volume of water delivered for agricultural use, except as otherwise provided in subdivision (f) of Section ͭͬͲͬʹ.ͮͰ.
“Gross Water Use” is the total volume of water, whether treated or untreated, entering the distribution system of an urban retail water supplier with certain acceptable exclusions. Gross water use is reported for each year in the baseline periods as well as ͮͬͮͬ, the compliance year, in Table Ͱ of the SB Xͳ‐ͳ Verification Forms (Appendix F). The annual gross water values are the "total water into the system" reporting in the City’s Public Water System Statistics reports. This reflects the volume of water entering the system. These values do not account for losses in the distribution system.
5.4 Baseline Daily Per Capita Water Use
The baseline daily per capita water use in each of the baseline years is calculated in Table ͱ of the SB Xͳ‐ͳ Verification Form included in the ͮͬͭͱ UWMP (Appendix C) by dividing annual gross water use by annual service area population.
5.5 Baselines and Targets Summary
The Water Conservation Act of ͮͬͬ͵ (SB Xͳ‐ͳ) governs water conservation in California and requires water suppliers to increase water efficiency by decreasing per‐capita consumption by a State mandated ͮͬ percent by the year ͮͬͮͬ.
As mentioned above a supplier may update the baseline and target water use if there were changes to their distribution area. Since there has been no change in water service area, the baseline and target gpcd values from the ͮͬͭͱ UWMP are utilized in this UWMP to determine compliance with the ͮͬͮͬ target.
Using the ͭͬ‐year baseline, the City’s water use target for ͮͬͮͬ must be ͮͬ percent less than the baseline volume, resulting in ͭͱͲ gpcd and a ͮͬͭͱ interim water use target of ͭʹͳ gpcd to measure progress. Based on the ͮͬͭͱ UWMP, the gross water usage was ͭͯͬ gpcd, which was below the interim water use target. Furthermore, Section ͱ.ͱ.ͭ discusses the methodology in calculating the actual ͮͬͮͬ water use target.

5.5.1 Target Methods and Target Confirmation
10608.22. Notwithstanding the method adopted by an urban retail water supplier pursuant to Section 10608.20, an urban retail water supplier's per capita daily water use reduction shall be no less than 5 percent of base daily per capita water use as defined in paragraph (3) of subdivisions (b) of Section 10608.12. This section does not apply to an urban retail water supplier with a base daily per capita water use at or below 100 gallons per capita per day.
Four target methods have been developed, and identify the specific steps water suppliers shall follow to establish these targets. A brief description of each method, as well as the water use calculated using each methodology is included below, however the City utilized Method 3 to calculate their 2020 target, which is consistent with the 2015 UWMP.
5.5.1.1 Method 1 – 80 Percent of Base Daily Per Capita Water Use Method 1 requires an urban water supplier to first determine the base daily per capita use. In order to determine the target using Method 1, 80 percent of the base daily per capita use 10-year base period) is calculated. Based on the 10-year baseline daily per capita use of 195 gpcd determined previously, the target use for Method 1 is 156 gpcd.
5.5.1.2 Method 2 – Performance Standards
Method 2 requires water suppliers to use baseline CII, indoor residential, and landscaped area water use to calculate a water use target. Based on the nature of the data required to determine a target using Method 2, it is not feasible for the City to use this methodology.
5.5.1.3 Method 3 – 95 Percent of Hydrologic Region Target Method 3 requires water suppliers to use the hydrologic region target to calculate a water use target for 2020. In order to determine the target using Method 3, 95 percent of the regionspecific conservation goal is calculated. Based on a target of 188 gpcd for the Tulare Lake Region, the Method 3 target is 95 percent of the target resulting in 179 gpcd.
5.5.1.4 Method 4 – Savings by Water Sector
Method 4 identifies water savings obtained through identified practices and subtracts them from the base daily per capita water use value identified for the water supplier. The water savings identified that can be used to reduce the base daily per capita water use value include:
• Indoor residential use savings.
• Metered savings (not applicable since City is fully metered). • CII savings.
• Landscape and water loss savings.
To calculate the CII savings, a retail water supplier must have data for the entire baseline period used in the base daily per capita water use calculation. The City does not have metered CII usage data for the entire baseline.

5.6 2020 Compliance Daily Per Capita Water Use
10608.12(e) "Compliance daily per-capita water use" means the gross water use during the final year of the reporting period…
10608.20 (e) An urban retail water supplier shall include in its urban water management plan due in 2010 . . . compliance daily per capita water use, along with the bases for determining those estimates, including references to supporting data.
Compliance daily per-capita water use means the gross water use during the final year of the reporting period. Water suppliers are required to calculate their actual 2020 water use (2020 calendar year) and evaluate whether their per capita 2020 target use was met. Refer to Table 5.2 and SB X7-7 Table 9 for 2020 compliance. The City met the 2020 target of 179 gpcd in the year 2020 with an actual per capita water use of 133 gpcd. If consumption rates begin to rise, the City must implement additional conservation and/or efficiency measures to maintain below this target.

Chapter 6
SYSTEM SUPPLIES
The UWMPA requires that the UWMP include a description of the agency’s existing and future water supply sources for the next 20 years. The description of water supplies must include detailed information on surface water, groundwater, the groundwater basin, potential opportunities for desalination of groundwater and seawater, and detailed information on the agency’s imported water.
6.1 Water Supply Overview
The City water supply is strictly from extracted groundwater. The City has 36 active groundwater wells that are located throughout the City limits that pump directly to the distribution system or to various water storage tanks. Figure 3-2 displays the City’s distribution system, water storage tanks, and active groundwater wells.
6.2 Purchased or Imported Water
The City of Porterville does not import or purchase any raw or potable water for their public distribution system. The City has a total surface water allocation of approximately 2,039 ac-ft (664 MG). The City has acquired surface water rights in the amount of 468 shares from the Pioneer Water Companywhich is equivalent to approximately 1.5 ac-ft per share resulting in 236.5 MG. Additionally, the City has acquired approximately 14.5 ac-ft (4.7 MG) from Porter Slough Ditch Company and 1,300 ac-ft (423.6 MG) from Porterville Irrigation District. When available, the City purchases surface water supplies from nearby irrigation and water districts and utilizes for groundwater recharge. The City has been using their surface water allocation to augment their existing groundwater supply and to create a drought buffer during excessive extraction periods. Figure 6.1 shows the volume of surface water the City has used for groundwater recharge over the last ten years.

Figure 6.1 Purchased Surface Water Volume, MG (2010 – 2020)
6.3 Groundwater
The City of Porterville drinking water supply is solely from groundwater extraction wells. The City’s groundwater supply is extracted using 36 active wells scattered throughout the water service area that pump directly into the water distribution system and surrounding above ground water storage tanks. Extracted groundwater is chlorinated at the wellheads to provide disinfectant residual in the distribution system.
6.3.1 Basin Description
10631 (b) If groundwater is identified as an existing or planned source of water available to the supplier, all of the following information shall be included in the plan:
(2) A description of any groundwater basin or basins from which the urban water supplier pumps groundwater.
The City’s groundwater system is supplied from the east side of the Tule Sub-basin. The Tule sub-basin sits on a series of overlapping alluvial fan sedimentary deposits sourced from runoff from the Sierra Nevada mountain range east of the City. Near the City, the natural waterways that promote supply to the groundwater basin are Deer Creek and the Tule River. Tule River flow is managed by Lake Success for flood control and recreation at Lake Success located just east of the City. As described in the ETGSP, The Tule Subbasin consist of permeable sand and gravel layers, interbedded with low permeability silt and clay lenses. The transmissivity of the aquifer soils near the Tule River are high from loose soil river deposits. DWR records indicate that the groundwater elevation is approximately 300 feet below ground surface. 1312

6.3.2 Groundwater Management
10631 (b) If groundwater is identified as an existing or planned source of water available to the supplier, all of the following information shall be included in the plan:
(1) A copy of any groundwater management plan adopted by the urban water supplier… or any other specific authorization for groundwater management.
Porterville is part of the Eastern Tule GSA which in part has outlined various projects and management actions that are to be taken by the City and the surrounding water purveyors to meet the groundwater sustainable yield goals set in the GSP. The adopted ETGSP is attached to this plan in Appendix G.
6.3.3 Overdraft Conditions
10631 (b)(2) For basins that have not been adjudicated, (provide) information as to whether the department has identified the basin or basins as overdrafted or has projected that the basin will become overdrafted if present management conditions continue, in the most current official departmental bulletin that characterizes the condition of the groundwater basin, and a detailed description of the efforts being undertaken by the urban water supplier to eliminate the longterm overdraft condition.
The Eastern Tule GSP, outlines that historically, the Tule Subbasin has been subject to overdraft conditions by excessive groundwater pumping.Per the GSP, overdraft is estimated to be approximately 61,000 acre-feet/year for the region within the ETGSA boundary. The ETGSP presents the need for a sustainable yield in order to address overdraft conditions in the future for the entire region. The Eastern Tule GSA has outlined management actions that are to be taken by the City and the surrounding water purveyors to meet the groundwater sustainable yield goals set in the GSP. The sustainable goals are intended to balance average annual inflows and outflows of water in the groundwater basin by 2040 so that negative change in storage does not occur after 2040 ultimately avoiding undesirable and potentially catastrophic conditions of the groundwater subbasins. The current sustainable yield for the City is calculated as 1.01 ac-ft/acre of the City’s UDB. The City’s extraction volume within its native sustainable yield and total precipitation allocation is approximately 17,355 AFY which is about 5,655 MG. The sustainable yield is subject to revision every year due to current drought conditions, groundwater use and supply management measures. These measures ultimately seek to achieve the following criteria:
• Increase available water supplies.
• Optimize existing water supplies.
• Decreased consumptive use of non-sustainable groundwater supplies to mitigate overdraft.
• Groundwater levels sustained to sustainable management criteria quantified in this Plan.
• Reduction or cessation of subsidence near critical infrastructure. • Stabilized water quality for agronomic and municipal beneficial uses. • Funding for local water management.
• Improved collection and management of water related data within the Agency.
CITY OF PORTERVILLE | 2020 URBAN WATER MANAGEMENT PLAN| CH 6 SYSTEM SUPPLIES 6-4 | JANUARY 2022 | DRAFT FINAL
The implementation of projects and management actions are expected to provide a collective benefit for not only the City but the surrounding users. In general project types and management actions that are considered to be implemented in the future fall under four groups:
1. Water Supply Optimization: Optimizing efficiencies in existing surface water or groundwater operations.
2. Surface Water Development: Developing new surface water supplies.
3. Managed Aquifer Recharge and Banking: Developing recharge and groundwater banking projects.
4. Agricultural Land Retirement: Projects related to fallowing agriculture land.
The project and management action categories provide a roadmap in reaching a sustainable water resource utilization on a regional basis which ultimately trickles down to the individual user. The GSP will develop improved practices in distributing, integrating, exchanging, recharging, and managing water supplies to create a sustainable environment for groundwater resources for the City and the surrounding areas.
6.3.4 Historical Groundwater Pumping
10631 (b) …If groundwater is identified as an existing or planned source of water available to the supplier, all of the following information shall be included in the plan:
(3) A detailed description and analysis of the location, amount, and sufficiency of groundwater pumped by the urban water supplier for the past five years.The description and analysis shall be based on information that is reasonably available, including, but not limited to, historic use records.
The City of Porterville has historically relied on groundwater wells to supply its drinking water distribution system. The City has 36 active wells that are currently in service and are located throughout the City. Before 2014, the City’s groundwater demand was much higher than it is today. For example, the groundwater supplied to the City averaged 4,150 MG between 2002 and 2014 and an average of 3,378 MG between 2015 and 2020. The severe drought of 2011 - 2017 drastically increased the City’s conservation efforts ultimately leading to a decrease in groundwater pumping. The City’s groundwater supply is summarized in Table 6.1.

6.4 Surface Water
The City of Porterville does not import or purchase any raw surface water from the nearby Friant-Kern Canal or from adjacent irrigation district for their public drinking water distribution system. The City does have surface water allocations from the Pioneer Water Company, Porter Slough Ditch Company, and Porterville Irrigation District which they use for groundwater recharge or recharge credits as water is available.
6.5 Stormwater
The City of Porterville’s storm water collection system is a separated from the sanitary sewer collection system. The City stormwater collection system conveys captured runoff to retention/recharge basins or directly to flood channels that run throughout the City. There are two scales of stormwater which are potentially relevant to the City’s water supply portfolios, the first is the hydrological dependent surface water supplies from runoff in the region. The second is the volume of stormwater captured in the City’s collection system. The benefit of stormwater in the grand scheme of the City’s water supply portfolio is minimal, therefore it is not further evaluated in their assessment and the City does not reuse stormwater for their potable water supply.
6.6 Wastewater and Recycled Water
The UWMPA requires that the UWMP address the opportunities for development of recycled water, including the description of existing recycled water applications, quantities of wastewater currently being treated to recycled water standards, limitations on the use of available recycled water, an estimate of projected recycled water use, the feasibility of said projected uses, and practices to encourage the use of recycled water.
6.6.1 Recycled Water Coordination
10633. The plan shall provide, to the extent available, information on recycled water and its potential for use as a water source in the service area of the urban water supplier. The preparation of the plan shall be coordinated with local water, wastewater, groundwater, and planning agencies that operate within the supplier's service area.
The City of Porterville 2020 Recycled Water Feasibility Study (RWFS) outlines various alternatives to provide recycled water for beneficial use to the surrounding area. The City has been coordinating with local irrigation and water districts investigating the potential demand for recycled water produced from the City’s wastewater. The feasibility study concluded that the City’s most beneficial use of recycled water was to provide three adjacent irrigation districts:
Porterville Irrigation District (PID), Tea Pot Dome Irrigation District (TPDID), and Saucelito Irrigation District (SID) with tertiary treated disinfected recycled water to be used for unrestricted agricultural irrigation in exchange for surface water allocations. The City in turn plans to initiate the preliminary development of producing an advanced treatment recycled water facility in the near future as part of their Alternative Compliance Project for the California Central Valley (CV) Salts Program.

6.6.2 Wastewater Collection, Treatment Systems, and Disposal 10633. (a) (Describe) the wastewater collection and treatment systems in the supplier's service area, including a quantification of the amount of wastewater collected and treated and the methods of wastewater disposal.
The City of Porterville currently collects sanitary sewer from the City service area shown in Figure 3-1. The City owns and maintains approximately 2,728 manholes, 24 lift stations, 9,880 feet of force mains and 48.4 miles of gravity sewer pipes. The City also receives and treats wastewater from the Porter Vista Public Utilities District (PVPUD) from East Porterville.
The City of Porterville owns and operates the wastewater treatment facility (WWTF) which receives and treats all wastewater from residential, commercial, and industrial discharges within the City as well as from the Porterville State Hospital and the PVPUD. The WWTF is located west of the town center on the corner of N. Prospect St. and W. Morton Avenue near Veteran’s Park.
The City’s WWTF was built in 1954 with a capacity of 1.8 million gallons per day (mgd) and upgraded to 4.0 mgd in 1978 to provide capacity for future growth and for the addition of existing developments which previously depended on individual disposal systems (septic tanks).
In 1994 the WWTF was expanded to increase the average day maximum month flow (ADMMF) from 4.0 mgd to 8.0 mgd.
The City’s WWTF Waste Discharge Requirement Order No. R5-2008-304 restricts the monthly average daily discharge to 5.3 mgd. The 2020 wastewater flows from the City’s service area is summarized in Table 6.2. As shown in Table 6.2, the City contributed a total of 1,712 MG (4.69 mgd) of wastewater flow into the WWTP in 2020.

The existing WWTF provides activated sludge secondary treatment. The primary treatment process starts with the influent wastewater from the sewer collections system to the headworks which screens out large debris such as rags, trash, and other obstructions. Screened wastewater is pumped from the headworks pump station and through a Parshall flume to measure flow and then to an aerated grit chamber to collect smaller grit-like particles in the system. From the aerated grit chambers wastewater is sent to the primary clarifiers allowing additional solids to settle and sum to float to the surface.
Following primary treatment process, wastewater is conveyed to the aeration basins where the activated sludge process begins. From the aeration basins, wastewater is then sent to the secondary clarifiers allowing the mixed liquor from the aeration basins to settle and it’s either returned to the aeration basins or wasted to the dissolved air flotation thickeners (DAFT) for sludge thickening.
6.6.3 Wastewater Treatment and Discharge within Service Area After the secondary treatment process, treated wastewater effluent is pumped to the reclamation area through a 4.5 miles pipeline to the southwest area of town center near the Porterville Municipal Airport where it is applied on the effluent irrigation areas or percolated into the ground via percolation basins. Sludge from the DAFT and primary clarifiers is sent to the anaerobic digester for processing to produce methane gas. From the digester, treated sludge is pumped from the biosolids transfer station located adjacent to the anaerobic digesters through a 4.5 mile pipeline to the sludge drying beds located near the City Municipal Airport. Once dry, biosolids are applied on the effluent irrigation areas as directed in the City’s Biosolids Management Plan and annual Biosolids pre-application. Table 6.3 identifies the volume of treated wastewater either recycled or disposed of within the service area.

6.6.4 Recycled Water System Description
10633. (c) A description of the recycled water currently being used in the supplier’s service area, including, but not limited to, the type, place, and quantity of use.
The City currently has a total of 880 acres available for biosolids application which includes a total of 630 acres within the reclamation area with the remaining 250 acres located in the Cityowned dry-farmed area adjacent to the airport. Therefore, a total of 630 acres are available to receive effluent for irrigation and biosolids application. The City also utilizes approximately 48 acres of percolation ponds for groundwater infiltration which is also shown in. Figure 6.2 shows that average monthly effluent discharged to either the percolation ponds or the irrigation areas is approximately 130 MG. Typically, biosolid application and effluent irrigation is applied heavily during the summer months, May to September, and effluent is discharged to the percolation ponds for groundwater infiltration October through April.

6.6.4.1 Recycled Water Beneficial Uses
The range of beneficial uses of recycled water for the City are separated into five different reuse categories. Each category is listed below with a brief description in respect to the City’s water system specifically.
Restricted Agricultural Reuse
Undisinfected secondary treated recycled water is discharged to City-owned agricultural property for the irrigation of fodder crops and percolation. This s the City’s current recycled water program.
Unrestricted Agricultural
Water could be used to continue the City’s existing recycled program as well as provide supply to districts close to the City.
Landscape Irrigation
Disinfected tertiary recycled water would be supplied to landscape irrigation users for domestic, commercial, and municipal properties within the vicinity of the existing WWTP or a recycled water distribution line.

CITY OF PORTERVILLE | 2020 URBAN WATER MANAGEMENT PLAN| CH 6 SYSTEM SUPPLIES Potable Reuse by Groundwater Replenishment
Recycled water meeting Title 22 requirements for advanced treatment beyond disinfected tertiary standards would be used for groundwater recharge by surface spreading in recharge basins. Groundwater percolation provides an environmental buffer with adequate retention time until groundwater is extracted using City’s municipal wells.
Direct Potable Reuse
Potable reuse by raw water augmentation of the City’s drinking water supply by comingling highly purified recycled water with surface water in a proposed surface water treatment plant.
There is no environmental buffer to direct potable reuse, rather an engineered storage of the purified recycled water.
6.6.5 Potential, Current, and Planned Uses of Recycled Water 10633. (b) A description of the quantity of treated wastewater that meets recycled water standards, is being discharged, and is otherwise available for use in a recycled water project. (d) A description and quantification of the potential uses of recycled water,including, but not limited to, agricultural irrigation, landscape irrigation, wildlife habitat enhancement, wetlands, industrial reuse, groundwater recharge, indirect potable reuse, and other appropriate uses, and a determination with regard to the technical and economic feasibility of serving those uses. (e) The projected use of recycled water within the supplier’s service area at the end of 5, 10, 15, and 20 years, and a description of the actual use of recycled water in comparison to uses previously projected pursuant to this subdivision.
As discussed in Section 6.6.4 – Recycled Water System Description, theCity currently percolates undisinfected secondary treated wastewater effluent to designated groundwater infiltration basins and uses the same effluent as fodder crop irrigation heavily during the summer months.
The City recently completed a 2020 Recycled Water Feasibility Studywhich analyzed the potential recycled water market within the City.The result of thisStudy has provided a recommendation for theCity to provide unrestricted agricultural irrigation supply water (disinfected tertiary treated recycled water) to nearby irrigation districts (PID, TPDID, SID). The current and projected recycled water uses are summarized in Table 6.4. The projected recycled water volumes are based on theCity’s 2020 Recycled Water Feasibility Study.
The City plans to implement a WWTP denitrification upgrade as well as produce tertiary treated disinfected recycled water for unrestricted agricultural irrigation within the next 5 to 8 years. For this UWMP, it is assumed that by 2025 the Citywill be producing recycled water, however this is subject to change in thecoming years. It is expected that the recycled water will be supplied to surrounding irrigation districts for distribution to customers with surface water exchange agreements in place for groundwater recharge as well as water supply augmentation via surface water treatment in the future. The recycled water feasibility study analyzed thetotal production of recycled water based on the 2040 projected plant effluent of 8.84 mgd (3,227 MG or 9,920 AFY). The surrounding irrigation districtswho have preemptively agreed to accept recycled water would each on their own be able to consumethe full amount of projected flow on a month-to-month basis, however contractual agreement negotiations have not occurred. The recycled water use projection for 2020 from the2015 UWMP is compared to the 2020 actual use in Table 6.5. In the interim, the City’s recycled water effluent volumeis expected to increase with population and development growth within the UDB.

6.6.6 Actions to Encourage and Optimize Future Recycled Water Use 10633. The plan shall provide, to the extent available, information on recycled water and its potential for use as a water source in the service area of the urban water supplier… and shall include the following:
(g) A plan for optimizing the use of recycled water in the supplier’s service area, including actions to facilitate the installation of dual distribution systems, to promote recirculating uses, to facilitate the increased use of treated wastewater that meets recycled water standards, and to overcome any obstacles to achieving that increased use.
The use of a recycled water facility to provide a drinking water supply through either offsetting potable water use for landscape irrigation, groundwater augmentation, or surface water comingling and treating has been rejected by the City. Due to the location and reclamation limitations of the City, advanced treatment and purification is an uneconomical solution due to the discharge requirements of an advanced treatment system. Being said, as discussed in the Recycled Water Feasibility Study, the City has begun the process in developing an expanded recycled water program to create a reliable unrestricted agricultural irrigation water supply in exchange for reliable surface water right exchanges that can potentially be used for a groundwater basin or feed a surface water treatment plant in the future. Table 6.6 shows the City’s near future projected recycled water production.

6.7 Desalinated Water Opportunities
10631(d). Describe the opportunities for development of desalinated water, including, but not limited to, ocean water, brackish water, and groundwater, as a long-term supply.
The City does not utilize any desalinated water for their domestic water supply.
6.8 Exchanges or Transfers
10631(d). Describe the opportunities for exchanges or transfers of water on a short-term or longterm basis.
The UWMPA requires the UWMP to address the opportunities for development of short or longterm transfer or exchange opportunities.
6.8.1 Exchanges or Transfers
Water exchanges entail water being delivered by one water user to another water user, with the receiving water user providing water in return at a specified time or when the conditions of the parties' agreements are met. As outlined in the Recycled Water Feasibility Study, if the City is providing irrigation water supply to nearby irrigation districts, the opportunity for Friant-Kern Canal (FKC) surface water exchanges with those irrigation districts is a likely possibility. This surface water would be used to feed groundwater recharge basins or a surface water treatment plant. Presently, the City does not have any exchange agreements with adjacent irrigation districts between FKC surface water and recycled water, however negotiations are expected to begin in the near future.
6.8.2 Emergency Interties
The City does not have any emergency interties with surrounding agencies. As mentioned in Section 6.3, the City’s source of water is solely from groundwater wells and does not have any supplementary drinking water supply to its system.
6.9 Future Water Projects
10631(f)… The urban water supplier shall include a detailed description of expected future projects and programs that the urban water supplier may implement to increase the amount of the water supply available to the urban water supplier in normal and single dry water years and for a period of drought lasting five consecutive water years. The description shall identify specific projects and include a description of the increase in water supply that is expected to be available from each project. The description shall include an estimate with regard to the implementation timeline for each project or program.
As discussed in Section 6.6.5, the City intends to upgrade their existing WWTP and supporting effluent infrastructure to supply tertiary treated disinfected recycled water for unrestricted agricultural irrigation to nearby irrigation districts. This in turn will provide the opportunity for the City to enter into surface water exchange agreements with the irrigation districts surface water allocation for groundwater recharge from either the Friant Kern Canal. Ultimately this exchange enables the City to actively increase groundwater recharge efforts and potentially construct a surface water treatment plant in the future. Additionally, the City’s anticipates the installation of three new wells on the west side of the UDB to provide an additional capacity up to 3.3 mgd to the potable water distribution system to reduce the supply deficit between the CITY OF PORTERVILLE | 2020 URBAN WATER MANAGEMENT PLAN| CH 6 SYSTEM SUPPLIES 6-14 | JANUARY 2022 | DRAFT FINAL
maximum day demand (MDD) and the existing firm supply. The City’s IMP also investigated the augmentation of their existing water supply portfolio with the addition of 12 new wells within the water service area to meet the 2040 projected future maximum day demands. The City plans to utilize these future water projects regardless or normal or consecutive drought years to expand their water system within their UDB to meet daily demands within their water service area. The City investigated the feasibility of a direct potable reuse water supply alternative in their 2020 RWFS. DPR includes combining highly treated recycled water with potable groundwater water to augment drinking water supply directly. The high cost of advanced treatment and the requirement to dispose of RO concentrate eliminated this alternative from the City’s water supply portfolio alternatives. Table 6.7 presents the City’s expected future water supply programs and their anticipated implementation time.

10631 (b) Identify and quantify, to the extent practicable, the existing and planned sources of water available to the supplier over the same five-year increments described insubdivision (a), providing supporting and related information, including all of the following… (b)(2) When multiple sources of water supply are identified, a description of the management of each supply in correlation with the other identified supplies. (h) An urban water supplier that relies upon a wholesale agency for a source of water shall provide the wholesale agency with water use projections from that agency for that source of water in five-year increments to 20 years or as far as data is available. The wholesale agency shall provide information to the urban water supplier for inclusion in the urban water supplier’s plan that identifies and quantifies, to the extent practicable, the existing and planned sources of water as required by subdivision (b), available from the wholesale agency to the urban water supplier over the same five-year increments, and during various water-year types in accordance with subdivision (f). An urban water supplier may rely upon water supply information provided by the wholesale agency in fulfilling the plan informational requirements of subdivisions (b) and (f).
6.10.1 Description of Supplies
As discussed in Section 6.3, 6.4, and 6.5, theCity’s main and only source of potable water is groundwater with undisinfected secondary treated recycled water used as restricted agricultural irrigation for fodder crops as a means of groundwater recharge and effluent disposal. In the future, the CityPlans to expand itswater supply portfolio by upgrading their existing WWTP to full tertiary treatment with disinfection to provide recycled water for unrestricted agricultural irrigation to surrounding irrigation districts in exchange for surface water rights for groundwater recharge and/or surface water treatment.
6.10.2 Quantification of Supplies
The actual source and volume of water for the year 2020 is presented in Table 6.8. With the implementation of Sustainable Groundwater Management Act (SGMA) and the acceptance of the ETGSP, groundwater supply availability in the Tule subbasin is quantified by the City’s sustainable yield. As discussed in Section 6.3.2, the sustainable yield is the volume of water the City can safely extract from the aquifer without causing excessive overdraft conditions in the future. The City’s 2020 Integrated Master Plan Water Supply Assessment investigates detailed water supply portfolio alternatives the City should consider in the future in order to diversify and expand its water supply. Presently, theCity’s groundwater volume is equivalent to the sustainable yield calculated in section 6.3.3. The City’s projected 2040 extraction volume within its native sustainable yield and total precipitation allocation is approximately 17,355 AFY (5,655 MG) which is about 2,008 MG (6,162 AF) above existing pumping conditions. The recycled water quantification is simply the treated wastewater effluent volume that is available for percolation into the City’s groundwater recharge ponds. The surface water (not desalinated) is the City’s total surface water allocations from adjacent irrigation districts. Chapter 7 further discusses the supply and demand balance considering thesupply fluctuations from drought conditions and variations in demand.

6.11 Special Conditions
This section describes any special conditions that could potentially affect the City’s water supply presently or in the future.
6.11.1 Climate Change Effects
Increasing temperatures, drought conditions, and population growth will likely increase water demands for the City in the future. To augment the groundwater supply working towards both their GSP and General Plan goals, the City currently recharges treated wastewater effluent into groundwater percolation basins at their reclamation site near the municipal airport. In the future, the potentialfor surface water exchanges with nearby irrigation districtswill add additional supply for groundwater recharge and potentially surface water treatment. Effects from climate change can potentially decrease the availability of surface water in the FKC given the allocation volumes therefore reducing the availability of surface water for theCity’s use and further reducing supplies To investigate the effects of climate change on the projected averages of hydrologic parameters such as precipitation, snowfall, surface runoff, and temperature, the CalAdapt extended drought scenario tool was used to explore possible impacts resulting from climate change.
As discussed, the City’s supply is completely dependent upon seasonal hydrologic conditions via precipitation in the valley or accumulated snowpack in the Sierra Nevada mountains. Cal-Adapt Extended Drought tool displays hydrologic data projected to specific date ranges of this upcoming century. Early Century is considered 2023 to 2042 and late century 2051 to 2070.This tool explores data for two 20-year drought scenarios, earlier and latter part ofthe century, derived from meteorological and hydrological simulations. Cal Adapt includes projected max/min temperatures, precipitation, evapotranspiration, snow water equivalent, and runoff values for a period of an extended drought period of up to 20 years. Data from the Cal-Adapt Extended Drought Tool was analyzed to summarize the potential impacts on water supplies related to climate change with respect to historical data. In summary, the model shows the effects from climate change can likely reduce the annual precipitation averages in future.
Table 6.10 shows theprojected hydrologic parameters listed in the model for theCity’s water service area. Appendix J includes additional informational outputs from the Cal-Adapt Extended Drought Simulation Tool.

As discussed with the implementation of SGMA and the ETGSP, the City must strive to extract groundwater within their sustainable yield volume. Presently, the City is well beneath the quantified sustainable yield volumes and plans to expand groundwater production efforts for system reliability and augmentation to meet existing and future maximum day demands.
Additionally, as development within the City continues, all new water service connections will require meters to monitor consumption and demands.

CH 7 WATER SYSTEM RELIABILITY AND DROUGHT RISK ASSESSMENT | 2020 URBAN WATER MANAGEMENT PLAN | CITY OF PORTERVILLE DRAFT FINAL | JANUARY 2022 | 7-1
Chapter 7
WATER SYSTEM RELIABILITY AND DROUGHT
RISK ASSESSMENT
The UWMPA requires that the UWMP address the reliability of the agency’s water supplies. This includes supplies that are vulnerable to seasonal or climatic variations. In addition, an analysis must be included to address supply availability in a normal year, a single-dry year and in fiveconsecutive years of drought. 10635 (a) Every urban water supplier shall include, as part of its urban water management plan, an assessment of the reliability of its water service to its customers during normal, dry, and multiple dry water years. This water supply and demand assessment shall compare the total water supply sources available to the water supplier with the long-term total projected water use over the next 20 years, in five-year increments, for a normal water year, a single dry water year, and a drought lasting five consecutive water years. The water service reliability assessment shall be based upon the information compiled pursuant to Section 10631, including available data from state, regional, or local agency population projections within the service area of the urban water supplier.
7.1 Constraints of Water Sources
10631 (b)(1) A detailed discussion of anticipated supply availability under a normal water year, single dry year, and droughts lasting at least five years, as well as more frequent and severe periods of drought, as described in the drought risk assessment. For each source of water supply, consider any information pertinent to the reliability analysis conducted pursuant to Section 10635, including changes in supply due to climate change There are two aspects of supply reliability that can be considered. The first relates to immediate service needs and is primarily a function of the availability and adequacy of the supply facilities.
The second aspect is climate-related and involves the availability of water during mild or severe drought periods. This section examines the reliability of the water supply available to the City.
7.1.1 Water Supply Quality
Appendix H contains the Annual Consumer Confidence Report (CCR) for the City’s service area for the year 2020. The City’s groundwater quality has been consistently good over the last ten years with the exception of moderately high nitrate concentrations in some areas due to historical irrigation practices. The City shallow wells (less than 300 feet deep) show increased nitrate concentrations over the last 12 years, however the elevated levels ranged between 3.6 to
6.8 milligrams per liter (mg/L) which is still below the MCL.As for the deeper City wells, CITY OF PORTERVILLE | 2020 URBAN WATER MANAGEMENT PLAN| CH 7 WATER SYSTEM RELIABILITY AND DROUGHT RISK ASSESSMENT 7-2 | JANUARY 2022 | DRAFT FINAL
(>300 feet), the nitrate concentrations ranged from 1 to 5.5 mg/L, however it is expected that the increased influence in nitrate concentration is from downward flow of shallow groundwater to greater depths when water levels were deeper. The City has the opportunity to improve the groundwater quality by avoiding construction of new wells near the surface water features throughout the City to enable effective groundwater recharge as well as groundwater recharge from surface water application on sandy soil areas typically adjacent to the Tule River.
7.1.2 Climate
The constraints to the City’s water source is discussed in Section 4.6 and 6.3.
7.1.3 Potential Alternative Sources
As discussed in Chapter 6, presently the City’s existing water supply is sourced solely from groundwater. The City also received surface water allocations from the Pioneer Water Company, Porter Slough Ditch Company, and Porterville Irrigation District that are utilized for groundwater recharge. When surplus surface water allocations are available the City purchases additional surface water from nearby irrigation districts for additional groundwater recharge. The City’s IMP outlines the need for the City to increase its groundwater water supply through expansion of their existing well system as well as groundwater recharge from surface water right exchanges with adjacent irrigation districts. Ultimately, the access to surface water gives the City the opportunity to investigate a surface water treatment plant in the future. As discussed in Section
6.9, the City rejected the DPR water supply alternative in their RWFS.
7.2 Water Supply Reliability by Type of Year
This section considers the City’s water supply reliability during three water scenarios: average year, single-dry year, and five-consecutive-year drought. An average year is also referred to as a "normal" year.
These scenarios are defined as follows:
• Average year: a year, or an averaged range of years, that most closely represents the average water supply available to the City. Generally, a year that represents the average precipitation on record. Based on the historic DWR precipitation records from 1988 to 2020, calendar year 2015 best characterizes average year condition. • Single-dry year: The year that represents the lowest water supply available to the City in a single year. Based on historic DWR precipitation records from 1988 to 2020, the calendar year 2013 best characterizes single dry year conditions. • Five-Consecutive-Year Drought: the period that represents the driest five-year historical sequence for the City. Generally considered to be the lowest average runoff for a five-consecutive-year period. Based on historic DWR precipitation records from 1988 to 2020, the period from 2011 through 2015 best characterizes the five-year consecutive drought conditions.
7.2.1 Methodology
In the event of single and multiple dry years, reduced rainfall results in less groundwater recharge. The ETGSP has determined sustainable yields for the time being of the City of Porterville with respect to other agencies who utilize the Tule groundwater basin. The ETGSP determines the City’s sustainable yield from the Tule groundwater is about 17,355 AFY (5,655 MG), this volume is subject to change annually based on current drought conditions and CH 7 WATER SYSTEM RELIABILITY AND DROUGHT RISK ASSESSMENT | 2020 URBAN WATER MANAGEMENT PLAN | CITY OF PORTERVILLE DRAFT FINAL | JANUARY 2022 | 7-3
City usage. The volume is assumed to be projected to 2040 to represent the City’s sustainable yield to 2040. Currently and historically, the City’s demand is below the sustainable yield limit. In past period of drought, the City has met water demands with their existing groundwater supply, however water restrictions were set in place to reduce impacts on the existing well and distribution infrastructure and to alleviate strained groundwater elevations from dropping below existing wells.
7.2.2 Basis of Water Year Data
The specific years identified for average, single-dry, and five-consecutive-year drought presented in Table 7-1 were developed based on historical DWR runoff records for the City of Porterville and the availability of City’s records. The historic per capita demand is shown in Figure 7.1.

Consecutive Dry Years 4th Year 2014 3,877 124%
Consecutive Dry Years 5th Year 2015 3,117 100%
The years chosen to represent the dry-year scenarios were determined by examining precipitation records from DWR Success Lake (SCC) precipitation gage with historical data ranging from 1988 to 2020. The total precipitation average of the historical data shows 2015 as an average year for the City’s water supply. The per capita water demand in 2015 was 130 gpcd.
Figure 7.1 shows the average demand from 2015 to 2020 is around 130 gpcd as well as conservation efforts and customer water use behavior has changed as a result of the last major drought period from 2011 to 2017. 2013 shows the lowest single year precipitation therefore representing the single-dry year type with a per-capita water demand of 179 gpcd. The single dry year demand shows to be approximately 27-percent higher than the average per capita demand as a result of increased water usage from dry conditions. The historical precipitation records show the lowest average consecutive precipitation between 2011 and 2015. The average per capita demand between 2011 and 2015 starts at 163 gpcd in 2011 and peaks at 170 gpcd in 2013 and ending at 130 gpcd in 2015 as conservation efforts were implemented by the City to reduce demands. The City’s demand has historically been covered completely by groundwater through all year types with fluctuation in demands as conservation efforts are set in place. √
CITY OF PORTERVILLE | 2020 URBAN WATER MANAGEMENT PLAN| CH 7 WATER SYSTEM RELIABILITY AND DROUGHT RISK ASSESSMENT 7-4 | JANUARY 2022 | DRAFT FIN AL
For conservation planning, demands were not increased for the single dry-year since the value in 2013 is significantly higher than the present per capita demand between 2015 and 2020.
Additionally for the five-year consecutive dry condition, demands were not reduced due in part they are much higher than the present day demands and already represent a conservative planning approach to the City.

7.3 Water Service Reliability Assessment
10635(a). Every urban water Supplier shall include, as part of its urban water management plan, an assessment of the reliability of its water service to its customers during normal, dry, and multiple dry water years. This water supply and demand assessment shall compare the total water supply sources available to the water supplier with the long-term total projected water use over the next 20 years, in five-year increments, for a normal water year, a single dry water year, and a drought lasting five consecutive water years. The water service reliability assessment shall be based upon the information compiled pursuant to Section 10631, including available data from state, regional, or local agency population projections within the service area of the urban water supplier.
The projected demand and supplies are compared in 5-year increments in Table 7.2, Table 7.3, and Table 7.4.

7.3.1 Water Service Reliability - Normal Year
Table 7.2 provides an estimate of the projected normal year supply and demand totals. Demands are projected to increase to 8,322 MG in 2040. Under average year conditions the City will meet the majority of their demand with groundwater up to the sustainable yield allocation volume of the basin as well as the anticipated groundwater recharge through available surface water exchanges with nearby irrigation districts and surface water allocations already possessed by the City. The demand total for Table 7.2 shows the average year demand for only the potable water demand with the existing groundwater supply in addition to surface water recharge.
Table 7.2 Retail: Normal Year Supply and Demand Comparison – Potable and Non-Potable 2025 2030 2035 2040
Supply Totals(1) 8,542 8,834 9,166 9,539
Demand Totals(2) 5,731 6,497 7,337 8,322
Difference 2,812 2,337 1,829 1,217
Notes:
(1) Supply total assumes a 1:1 surface water exchange with recycled water with surrounding irrigation districts utilizing projected recycled water volumes as shown in the 2020 RWFS. (2) Demands include drinking water from Table 4-3
7.3.2 Water Service Reliability - Single-Dry Year
Table 7.3 provides an estimate of the projected single-dry year supply and demand totals.
Demand reductions due to water shortage stage rationing measures are not included in the single-dry year demand estimates.
As described in Section 7.2.2, the single-dry year demand was not increased since it is 27-percent greater than the average year and the 2015 to 2020 average water demand, therefore presenting an automatic conservative estimate with respect to current demands. This planning demand is consistent with the City’s 2020 IMP per capita water demand.
The surface exchanges were assumed to be 100 percent allocation from the FKC being that years prior to this single-dry year were hydrologically normal therefore reservoir levels were able to accommodate United States Bureau of Reclamation (USBR) water contractor demands. The surface water volume was based on a 40 percent ratio of extracted groundwater to metered wastewater effluent. The recycled water volumes were directly exchanged for surface water through the FKC to be used for groundwater recharge augmenting the basin. With the augmented groundwater supply, the City has a sufficient available volume to meet projected demands during the single dry year condition.

Supply Totals(1) 8,345 8,589 8,862 9,168
Demand Totals(2) 4,789 5364 6,007 6,728
Difference 3,556 3,225 2,855 2,440
Notes:
(1) Supply total assumes a 1:1 surface water exchange with recycled water with surrounding irrigation districts utilizing projected recycled water volumes as shown in the 2020 RWFS and a 100 MG per year groundwater recharge similar to historical City practices.
(2) Demands include potable water only with a 12% growth rate.

7.3.3 Water Service Reliability – Five-Consecutive-Year Drought Table 7.4 provides an estimate of the projected five-consecutive-year drought supply and demand totals. Similar to the single dry year, the water demands were not adjusted since they represent a conservative estimate in comparison to the City’s present day water use. The water demand during consecutive dry years is represented by the water demand between 2011 and 2015. The highest demand increase was a 6 percent increase from 2011 to 2012 and a 1 percent increase from 2012 to 2013. From the third year (2013) demands significantly reduce by 10 percent in above 2014 and by 20 percent in 2015.
Since the City has historically met all water needs regardless of hydrologic condition by groundwater and are still below their sustainable yield, the supply for all years included groundwater extraction to meet demand and groundwater recharge from the City’s existing allocation and surface water exchanges for recycled water with the nearby irrigation districts to increase supply. Similar to section 7.3.2, the surface water exchange volume was assumed to be 40 percent of the extracted groundwater and exchanged at a 1:1 ratio with surface water. It was assumed that the FKC allocation for surface water was 100 percent for the first year, 80 percent for the second year, 75 percent for the third year and was reduced to 50 percent for the fourth and fifth years. It was also assumed that groundwater recharge followed the same allocations as surface water percentages and was a portion of the City’s total allocation of 664 MG.
From the data shown in Figure 7.1, the reduction in demands between 2013 and 2015 is from the implementation of conservation efforts set by the City and continue to progress with a similar average demand to 2020 as a result of passive water conservation efforts by the customers.

7.3.4 Description of Management Tools and Options
10620(f). An urban water supplier shall describe in the plan water management tools and options used by that entity that will maximize resources and minimize the need to import water from other regions.
CH 7 WATER SYSTEM RELIABILITY AND DROUGHT RISK ASSESSMENT | 2020 URBAN WATER MANAGEMENT PLAN | CITY OF PORTERVILLE DRAFT FINAL | JANUARY 2022 | 7-7
Currently, the City of Porterville solely utilizes local groundwater supplies to meet potable water demands. The City plans to continue to use groundwater as its main water supply with groundwater recharge using surface water in the near future. Details of the groundwater recharge potential is discussed in Section 6.8 and 6.9
7.3.5 Seismic Risk Assessment and Mitigation Plan
10632.5(c). An urban water supplier may comply with this section by submitting, pursuant to Section 10644, a copy of the most recent adopted local hazard mitigation plan or multihazard mitigation plan under the federal Disaster Mitigation Act of 2000 (Public Law 106-390) if the local hazard mitigation plan or multihazard mitigation plan addresses seismic risk.
The Central San Joaquin Valley has an unlikely chance of seismic risk due to the soil type and the vicinity of active faults, however the risk is still possible for a significant seismic event to affect the City’s water assets. The Kern Canyon Fault Zone and the Owens Valley Faults are the only two fault systems that run through Tulare County that are reported by the United States Geological Survey (USGS), however the Kern Canyon Fault has been inactive since the 1930’s.
Additionally, the State’s largest fault system, the San Andres Fault, is not within Tulare County, but is nearby the western border. The largest earthquake ever recorded nearest to the City was a magnitude 5.0 in 1915. Being within Tulare County, Porterville is included within the Tulare County Multi-Jurisdictional Local Hazard Mitigation Plan (MJLHMP) as a participating agency.
The MJLHMP identifies Tulare County vulnerabilities to earthquakes as small since the County is not in a high hazard area for earthquakes The MJLHMP provides mitigation goals and actions for participating communities within the Plan. The 5 goals of the MJLHMP are listed below:
• Goal 1: Protect life, property, and reduce potential injuries from natural, technological, and human-caused hazards.
• Goal 2: Improve public understanding, support and need for hazard mitigation measures • Goal 3: Promote disaster resistance for the County’s natural, existing, and future built environment.
• Goal 4: Strengthen partnerships and collaboration to implement hazard mitigation activities.
• Goal 5: Enhance the County’s ability to effectively and immediately respond to disasters.
The mitigation measures associated with Earthquake risks and their corresponding hazard mitigation goals are listed in Table 7.6 below. The entire hazard mitigation list for all hazards are included in Table 6.2 of theMJHMP in Appendix L.

7.4 Drought Risk Assessment
10635(b) Every urban water supplier shall include, as part of its urban water management plan, a drought risk assessment for its water service to its customers as part of information considered in developing the demand management measures and water supply projects and programs to be included in the urban water management plan. The urban water supplier may conduct an interim update or updates to this drought risk assessment within the five-year cycle of its urban water management plan update. The drought risk assessment shall include each of the following…
(3) A comparison of the total water supply sources available to the water supplier with the total projected water use for the drought period. [Emphasis added] (4) Considerations of the historical drought hydrology, plausible changes on projected supplies and demands under climate change conditions, anticipated regulatory changes, and other locally applicable criteria.
CWC Section 10635(b) is a new requirement for the 2020 UWMPs where suppliers are required to prepare a DRA with descriptions of data and methods used, basis for the supply shortage conditions, determination of the reliability of sources, and a comparison of the total water supplies and uses during the drought. The DRA will be submitted every five years in addition to conducting an annual water supply and demand assessment. Evaluation for the DRA is based on the five dry years with consideration of climate changes, regulations, and other local criteria. In the event of stressed hydrologic conditions, suppliers will consider management of their water supplies in relation to customer usage, identify potential system vulnerabilities, and provide explanations of assumptions and decisions on which the analysis was based.
A summary of the City’s water supply drought risk assessment from 2021 through 2025 is summarized in Table 7.6. As discussed, the City presently and historically has met all of their demands from groundwater and actively uses surface water allocations for groundwater recharge. Groundwater recharge is not assumed to be a WSCP planned action since it’s the City’s status quo.Additionally, the City is still well below their sustainable yield value as indicated in the ETGSP therefore there is sufficient supply to meet anticipated demands within the next five years. The DRA report is included in Appendix J, which included additional details regarding potential supply vulnerabilities.

7.5 Regional Supply Reliability
10620 (f) an urban water supplier shall describe in the plan water management tools and options used by that entity that will maximize resources and minimize the need to import water from other regions.
As described in Chapter 6, the City does not utilize imported water within its service area for domestic use. The City uses imported surface water only for groundwater recharge. In the near future, the City intends to utilize imported surface water exchanges with recycled water for groundwater augmentation projects. Currently, negotiations and agreements with nearby irrigation districts have not been initiated. The future groundwater recharge efforts by the City are intended to reduce the impacts to the groundwater basin from over drafting conditions and to increase the reliability of the groundwater basin for continued use by the City in the future.
The potential to utilize the surface water received via exchanges may also be utilized for a surface water treatment facility in the future by the City to further diversify their water supply portfolio.

Chapter 8
WATER SHORTAGE CONTINGENCY PLAN
In response to the severe drought of 2012-2016, new legislation in 2018 created a Water Shortage Contingency Plan (WSCP) mandate replacing the water shortage contingency analysis under former law. The new requirements are more prescriptive to drive consistency throughout California.
The City has an existing Water Conservation Plan (WCP), which serves as theWSCP and is a stand-alone document. The WCP is included in Appendix I of this Urban Water Management Plan (UWMP). Because the WSCP is separate from the UWMP, it can be amended as needed without amending the 2020 UWMP.
To fulfill the requirements of California Water Code (CWC) § 10632, the WSCP includes the following required elements in addition to details unique to the City’s supply, location, and service area characteristics:
• Water Supply Reliability and Drought Risk Assessment. • Annual Water Supply and Demand Assessment Procedures. • Six Standard Water Shortage Levels.
• Shortage Response Actions.
• Communication Protocols.
• Compliance and Enforcements.
• Legal Authorities.
• Financial Consequences of WSCP Activation.

8.1 Water Supply Reliability and Drought Risk Assessment A Drought Disk Assessment (DRA), which includes the following components, is considered as part of the water supply reliability assessment:
• Description of the data, methodology, and basis for the supply shortage conditions for a drought period lasting five consecutive water years, starting from the year following the assessment year.
• Determination of the reliability of each water supply source under a variety of water shortage conditions.
• Total available water supply sources compared with total projected water use for the drought period.
• Considerations of historical drought hydrology, plausible changes to projected supplies and demands under climate change conditions, anticipated regulatory changes, and other locally applicable criteria.
CITY OF PORTERVILLE | 2020 URBAN WATER MANAGEMENT PLAN| CH 8 WATER SHORTAGE CONTINGENCY PLAN 8-2 | JANUARY 2022 | DRAFT FINAL
Chapter 7 of the UWMP provides a DRA based on five consecutive dry years from 2021 through 2025.The DRA shows that the highest projected demand for both the single dry year and multiple dry year scenarios was 6,728 MG in 2040. With the City’s continuous groundwater recharge activities, passive water conservation efforts already implemented in their conservation mandates, and the anticipated expansion of their surface water allocation with the upgrade of their existing WWTP to produce recycled water for unrestricted agricultural use, the City’s supply portfolio is well beyond the projected demand and falls within their anticipated sustainable yield of 5,655 MG. The City presently and historically has met all their demands from groundwater.
Additionally, the City is still well below their sustainable yield value and actively augments their supply by groundwater recharge. There is sufficient supply to meet projected demands within the next five years. The DRA report, included in Appendix J of the UWMP, includes additional details regarding potential supply vulnerabilities.
8.2 Annual Water Supply and Demand Assessment Procedures 10632.1An urban water supplier shall conduct an annual water supply and demand assessment pursuant to subdivision (a) of Section 10632 and, on or before July 1 of each year, submit an annual water shortage assessment report to the department with information for anticipated shortage, triggered shortage response actions, compliance and enforcement actions, and communication actions consistent with the supplier’s water shortage contingency plan… 10632(a)(2) The procedures used in conducting an annual water supply and demand assessment that include, at a minimum, both of the following:(A) The written decision-making process that an urban water supplier will use each year to determine its water supply reliability.(B) The key data inputs and assessment methodology used to evaluate the urban water supplier’s water supply reliability for the current year and one dry year, including all of the following… As required by CWC § 10632.1, the City must conduct a Water Supply and Demand Assessment (Annual Assessment) and must submit an annual Water Shortage Assessment Report (WSAR) based on that Annual Assessment on or before July 1 of each year starting in 2022. The focus of the Annual Assessment is based on actual forecasted near-term water supply conditions (over the next 12 months) to ensure appropriate shortage response actions are triggered in a timely manner with expected outcomes. The annual WSAR must contain information on any anticipated shortages, triggered shortage response actions, compliance and enforcement actions, and communication actions consistent with the City’s WSCP. The Annual Assessment will be conducted using the procedures and methods detailed in Appendix Q of the Department of Water Resources (DWR) UWMP guidance document. As required by CWC § 10632(a)(2), the procedures must include the elements detailed in the following sections.
8.2.1 Decision-Making Process
The City’s decision-making process for determining water supply reliability each year will be included in the WSAR:
1. City staff makes the determination that water supply conditions warrant a change in water shortage level.
2. City staff presents a request to the City Council for their approval of the change in water shortage level.
CH 8 WATER SHORTAGE CONTINGENCY PLAN | 2020 URBAN WATER MANAGEMENT PLAN | CITY OF PORTERVILLE DRAFT FINAL | JANUARY 2022 | 8-3
3. City staff monitors production capacity in order to make a determination on recommendations for moving from one water shortage level to the next. The decision to change water shortage levels will be based on a combination of surface water supplies, weather conditions, trends in water usage, groundwater levels, and well yield.
4. If efforts to reduce consumption in one water shortage level are not sufficient, then the next water shortage level is implemented. This progression continues until the highest water shortage level is reached.
8.2.2 Data Inputs and Water Supply Reliability Assessment Methodology The following data inputs and assessment methodologies used to evaluate the City’s water supply reliability for the current year and one dry year will be included in the WSAR. • Current Year Unconstrained Demand - Procedures for determining anticipated customer water needs for the current year considering factors like weather, growth, and policies to manage current supplies. This matches the methodology presented in Chapter 4 of the UWMP for projecting demand and allows for real-time adjustments to account for weather, prior-year conditions, anticipated new demands, land use, and customer use patterns.
• Current Year Available Supply - Procedures for evaluating current year available water supply considering factors like groundwater recharge, hydrological and regulatory conditions in the current year and one dry year, hydrologic forecasting, and restrictions based on prior year availability and use. Each year’s assessment is informed by characterizations in Chapter 6 of the UWMP.
• Infrastructure Capabilities and Constraints - Procedures to evaluate how existing capabilities and constraints may affect ability to deliver supplies to meet expected customer use needs in current year and one dry year. This would include anticipated capital projects to add capacity, or upcoming repairs or maintenance that may constrain capabilities, for example.
• Locally Applicable Criteria and Other Factors - Local criteria and how the City use it for the Annual Assessment; Local factors that can influence or disrupt supplies.
8.2.3 Description and Quantification of Each Water Supply Source Chapter 6 of the UWMP provides a detailed description of the City’s existing water supply and estimated future water supply sources over the next 20 years. The City’s sole source of water supply is strictly groundwater. The City has historically relied on groundwater wells to supply its drinking water distribution system. The City has 36 active wells that are currently in service and are located throughout the City. The City’s groundwater supply is summarized in Table 8.1.
Table 8.1 Retail: Groundwater Volume Pumped (MG)
Groundwater Type Location or Basin Name 2016 2017 2018 2019 2020 Alluvial Basin Tule Subbasin 3,222 3,345 3,515 3,422 3,647 Total 3,222 3,345 3,515 3,422 3,647
CITY OF PORTERVILLE | 2020 URBAN WATER MANAGEMENT PLAN| CH 8 WATER SHORTAGE CONTINGENCY PLAN The City’s water supply is quantified by adding sustainable yield plus groundwater recharge.
The City has plans to produce recycled water that it will both use for landscape irrigation and provide to nearby irrigation districts in exchange for surface water from the Friant-Kern Canal. It is the City’s expectation that the exchange rate will be 1:1. Surface water from the Friant-Kern Canal may then be used as recharge water in the City’s infiltration basins, or it may be source water for a future surface water treatment plant. Recycled water annual average daily flows (AADF) are projected to be 7.26 million gallons per day (MGD) in the year 2032 and 8.84 MGD in the year 2040.
8.3 Six Standard Water Shortage Levels
10632(a)(3) (A) Six standard water shortage levels corresponding to progressive ranges of up to 10, 20, 30, 40, and 50 percent shortages and greater than 50 percent shortage. Urban water suppliers shall define these shortage levels based on the suppliers’ water supply conditions, including percentage reductions in water supply, changes in groundwater levels, changes in surface elevation or level of subsidence, or other changes in hydrological or other local conditions indicative of the water supply available for use… As required by CWC § 10632(a)(3), the WSCP must include six standard water shortage levels representing shortages compared with normal reliability. The shortage levels are standardized to provide consistency regionally and statewide in response to the severe statewide drought of 2011-2017 and theresulting uncertainty associated with many different local definitions of water shortage stages. The six standard water shortage levels correspond to Up to 10%, up to 20%, up to 30 percent, up to 40 percent, up to 50 percent, and greater than 50 percent shortage in water supplies compared to demands under normal conditions.
These shortage levels are defined based on theCity’s water supply conditions including percentage reductions in water supply, changes in groundwater levels, changes in surface elevation or level of subsidence, or other changes in hydrological or other local conditions indicative of the water supply available for use. Shortage levels also apply to catastrophic interruption of water supplies, including, but not limited to, power outages, earthquakes, and other potential emergencies.
In concept,the six shortage levels represent an increasing gap between normal water supplies and normal customer water use. For example, the City may meet its anticipated customerwater use with 100 percent ofits available supply. At a 10 percent shortage level, the City must show its normally available supply is reduced by 10 percent and then identify locally appropriate shortage response actions (detailed further in Section 8.4) that would address theresulting gap.
The normally expected water supply and water use is characterized in Chapters 4 and 7 of the UWMP. Since use and supply typically vary monthly and seasonally, theshortage evaluation is on a monthly and/or seasonal basis.
An urban water supplier with an existing water shortage contingency plan that uses different water shortage levels may comply with the requirement by developing and including a crossreference relating its existing categories to thesix standard water shortage levels, also known as a “crosswalk". The City has elected to keep the previously established five water shortage phases from their WCP and add a sixth stage to classify supply shortage greater than 50%. A crosswalk between the City’s stages and DWR’s standard levels is shown in Figure 1. 8-4 | JANUARY 2022 | DRAFT FINAL

8.4 Shortage Response Actions
10632(a)(4) Shortage response actions that align with the defined shortage levels and include, at a minimum, all of the following:(A) Locally appropriate supply augmentation actions.(B) Locally appropriate demand reduction actions to adequately respond to shortages.(C) Locally appropriate operational changes.(D) Additional, mandatory prohibitions against specific water use practices that are in addition to state-mandated prohibitions and appropriate to the local conditions.(E) For each action, an estimate of the extent to which the gap between supplies and demand will be reduced by implementation of the action.
CWC § 10632(a)(4) requires that the WSCP include locally appropriate shortage response actions that align with the six defined water shortage levels. The specific response actions depend on the severity of the shortage levels, local conditions, and are based on a quantitative analysis of the effectiveness of each action.
These shortage response actions must include at a minimum the following:
• Supply augmentation.
• Demand reduction.
• Operational changes.
• Additional mandatory restrictions (in addition to state-mandated prohibitions). • Estimate of shortage response action effectiveness.
Table 8.2 lists the shortage response actions along with an estimate of the extent to which each shortage response action will reduce the gap between water supply and water demand. The expected magnitude of effectiveness or reduction benefit from a given action is based on water use changes that have occurred in response to implementing water shortage actions in the past.
Additionally, throughout all the shortage response actions the City continues to augment their groundwater supply surface water allocations become available year round.

Willful and egregious violations will result in issuance of a citation without a warning. Each day that a violation continues shall be regarded as a new and separate offense.
The City operates at Level 3 during the dry season (approximately June 1 to November 30) and Level 4 during the wet season (approximately December 1 to May 30). The primary Shortage Response Action associated with the transition from Water Shortage Level 2 to 3 is a reduction in outdoor water use from three days per week to two days per week. The magnitude of benefit for the City’s Shortage Response Actions for Water Shortage Level 3 is approximately a 25% reduction in per-capita water use.
Demand Reduction Actions
• Continuation of all demand reduction actions established in Water Shortage Levels 1 and 2 • Public Information Program – The utility billing system will begin to notify customers of restrictions on water use.

8.4.1 Eastern Tule Groundwater Sustainability Plan (GSP) Chapter 6 of the UWMP references the Eastern Tule Groundwater Sustainability Plan (GSP) with respect to groundwater management actions to be taken by the City to meet groundwater sustainable yield goals in response to overdraft conditions.Supply augmentation, demand reduction, and operational changes are already integrated into the criteria that the City seeks to achieve in their pursuit of the GSP’s sustainable yield goals. While Chapter 6 of the UWMP lists groups of management actions that the City will consider implementing to reach their sustainability goals, the WSCP lists specific actions with quantifiable benefits for each water shortage level.
8.4.2 Water Conservation Plan (WCP)
Section 25-32A.27 of the City Municipal Code states the following:
“The city council has adopted by resolution its water conservation plan which sets forth water conservation phases and conservation measures including mandatory restrictions on water usage by property owners and water consumers. Violation of the measures in effect, currently and as may be amended by resolution from time to time, pursuant to the applicable phase of the water conservation plan, shall be enforceable as set forth per any applicable remedy provisions in this code, including, but not limited to, sections 1-9 and 1-10 of this code, and chapter 2, article XIV of this code, and/or this division. The city's water conservation plan is deemed to be the city's "water shortage contingency plan" as per applicable state law. (Ord. 1830, 11-17-2015)”
The City’s existing WCP lists actions to be taken by the City for different water conservation phases. To meet the requirements of CWC § 10632(a)(4), these are realigned by a crosswalk with the six standard water shortage levels and adapted to include the minimum shortage response actions listed in Table 8.2.
8.4.3 Emergency Response Plan
In addition to the Shortage Response Actions listed in Table 8.2, the WSCP includes a description of how catastrophic shortages are tied to the water shortage levels. Catastrophic shortages caused by temporary disruptions to water supply and the City’s response actions to these shortages may already be adequately address in the City’s Emergency Response Plan (ERP).
Although the City does not have its own formal Emergency Response Plan (ERP) to address catastrophic interruptions in water supply, the shortage response actions listed in Table 2 could be used to reduce consumption following a temporary disruption to water supply. In addition, the City has back-up generators for their supply wells that can be employed in the event of a power outage.
The City was a participant in the coordinated preparation of the March 2018 Tulare County Multi-Jurisdictional Local Hazard Mitigation Plan (MJLHMP). The MJLHMPassesses the natural, technological, and human-caused risks to participating communities and proposes mitigation strategies to reduce the potential impact of the hazards. The 5 goals of the MJLHMP are listed below:
CITY OF PORTERVILLE | 2020 URBAN WATER MANAGEMENT PLAN| CH 8 WATER SHORTAGE CONTINGENCY PLAN • Goal 1: Protect life, property, and reduce potential injuries from natural, technological, and human-caused hazards.
• Goal 2: Improve public understanding, support and need for hazard mitigation measures.
• Goal 3: Promote disaster resistance for the County’s natural, existing, and future built environment.
• Goal 4: Strengthen partnerships and collaboration to implement hazard mitigation activities.
• Goal 5: Enhance the County’s ability to effectively and immediately respond to disasters.
In July 2021, the City submitted a Risk and Resilience Assessment (RRA) report to comply with America’s Water Infrastructure Act (AWIA) requirements. The RRA report includes a summary of best practices for reducing risk, a list of critical assets with their identified risks from malevolent threats and natural hazards, and an assessment of the City’s resilience level.
8.4.4 Seismic Risk Assessment and Mitigation Plan
Per CWC § 10632.5, a seismic risk assessment and mitigation plan is required to assess the vulnerability of the City’s water system facilities to seismic risks and to mitigate those vulnerabilities.
The MJLHMP identifies vulnerabilities to earthquakes in Tulare County and provides mitigation goals and actions for seismic risks for participating communities. The seismic risk mitigation measures and corresponding hazard mitigation goals listed in the MJLHMP are detailed in Chapter 7 and Appendix H ofthe UWMP. The MJLHMP is included in Appendix L. The City’s RRA report also assesses the vulnerability of the City’s water supplies to seismic risk.
8.5 Communication Protocols
10632 (a)(5) Communication protocols and procedures to inform customers, the public, interested parties, and local, regional, and state governments, regarding, at a minimum, all of the following:(A) Any current or predicted shortages as determined by the annual water supply and demand assessment described pursuant to Section 10632.1.(B) Any shortage response actions triggered or anticipated to be triggered by the annual water supply and demand assessment described pursuant to Section 10632.1.(C) Any other relevant communications.
As required in CWC § 10632(a)(5), the WSCP includes protocols and procedures for communicating with different stakeholders in the event of thedifferent water shortage levels as part of the WSCP implementation. The communications protocols includethe mechanisms used to inform customers, the general public, and interested parties as wells a local, regional, and state government entities. Communication mechanisms may include social media posts, bill stuffers or newsletters, press releases, radio spots, television coverage, and blog posts.
The decision-making process described in Section 8.2 triggers specific communications protocols to address each of thesix standard shortage levels, with a focus on communicating the shortage response actions, which are derived from theresults of theAnnual Assessment.
Emergency communications protocols are also included to address earthquakes, fires, infrastructure failures, civil unrest, and other catastrophic events. The City also participates in Reverse 911, an emergency alert system that sends text alerts directly to phones in Tulare County.Table 8.3 lists the communication protocols for the six standard water shortage levels. 8-16 | JANUARY 2022 | DRAFT FINAL

8.7 Legal Authorities
10632 (a)(7) (A) A description of the legal authorities that empower the urban water supplier to implement and enforce its shortage response actions specified in paragraph (4) that may include, but are not limited to, statutory authorities, ordinances, resolutions, and contract provisions.(B) A statement that an urban water supplier shall declare a water shortage emergency in accordance with Chapter 3 (commencing with Section 350) of Division 1.(C) A statement that an urban water supplier shall coordinate with any city or county within which it provides water supply services for the possible proclamation of a local emergency, as defined in Section 8558 of the Government Code.
This section lists all relevant statutory authorities, local ordinances, codes, resolutions, and water supply contract provisions that give the City legal authority to implement and enforce the shortage response actions listed in Table 8.2 and enforce them pursuant to the actions listed in Table 8.4.
Relevant Municipal Code sections:
• 25-32A.2 – Applicability to landscape projects.
• 25-32A.4 – Compliance with landscape documentation package. • 25-32A.12 – Irrigation scheduling.
• 25-32A.13 – Landscape and irrigation maintenance schedule. • 25-32A.23 – prescriptive compliance option.

• 2-144 – Civil/Administrative Fines and Administrative Costs.
In the event of a water shortage emergency, the City shall declare a water shortage emergency in accordance with CWC Chapter 3 (commencing with Section 350) of Division 1 general provision regarding water shortage emergencies. The City shall coordinate with any city or county within which it provides water supply services for the possible proclamation of a local emergency under California Government Code, California Emergency Services Act (Article 2, Section 8558).
8.8 Financial Consequences of WSCP Activation
10632 (a)(8) A description of the financial consequences of, and responses for, drought conditions, including, but not limited to, all of the following: (A) A description of potential revenue reductions and expense increases associated with activated shortage response actions described in paragraph (4).(B) A description of mitigation actions needed to address revenue reductions and expense increases associated with activated shortage response actions described in paragraph (4).(C) A description of the cost of compliance with Chapter 3.3 (commencing with Section 365) of Division 1.
The WSCP includes a description of potential reductions in revenue and increased expenses associated with the implementation of the shortage response actions described in Section 8.4 coupled with anticipated mitigation actions needed to address these financial impacts.
CH 8 WATER SHORTAGE CONTINGENCY PLAN | 2020 URBAN WATER MANAGEMENT PLAN | CITY OF PORTERVILLE DRAFT FINAL | JANUARY ͮͬͮͮ | ʹ‐ͮͭ
The City bills most of its customers on a volumetric basis. As a result, conservation measures, which aim to reduce water consumption, can also reduce revenue for the City. Significant water conservation during droughts can have a major impact on City revenues. Although the City would have lower water production costs with lower water deliveries, they also have considerable fixed and overhead costs that are the same for any volume of water delivered. As a result, conservation measures need to be coupled with rate adjustments to ensure that the water system is financially sustainable.
The City’s current WCP includes a ͮͬ% water rate increase on all residential and landscape accounts for the Phase V, or critical water supply shortage scenario. The higher unit rate is intended to discourage use, but it will also help to offset the revenue lost from selling a lower volume of water. The suitability of this ͮͬ% increase is not yet known, and it needs to be tested during a single‐year and multi‐year drought. If, in the future, the ͮͬ% price increase is found to be inadequate, the City will reevaluate the increase and modify it accordingly.
It is anticipated that implementation of the WSCP will not have a large impact on expenditures or revenues. No additional costs are expected for billing or operations. Existing City staff will provide the personnel needed to implement the plan and enforce water conservation measures.
It is likely that higher expenditures will be needed for public information programs, but these will probably be small compared to the total City water budget. Fines for water waste are a source of revenue, and they typically increase during droughts. However, the revenues from fines are also small compared to the overall City water budget.
The compliance and enforcement actions detailed in Section ʹ.Ͳ include a description of the fines associated with non‐compliance with the water shortage response actions.
8.9 Monitoring and Reporting
ͭͬͲͯͮ (a)(͵) For an urban retail water supplier, monitoring and reporting requirements and procedures that ensure appropriate data is collected, tracked, and analyzed for purposes of monitoring customer compliance and to meet state reporting requirements.
The WSCP includes a description of how the City will monitor and report on implementation of its WSCP. Monitoring and reporting is essential to ensure that the shortage response actions are achieving their intended water use reduction purposes. Monitoring can also help the City determine whether improvements or new actions need to be considered. Monitoring for customer compliance tracking is also useful in enforcement actions.
The State Water Board is preparing regulation for monthly reporting of water production, water uses, and enforcement metrics. When finalized, these will be summarized in the WSCP and incorporated by reference.
The City will be able to closely track groundwater pumping and any surface water deliveries on a daily basis. This data will be evaluated weekly to determine the effectiveness of the shortage response actions. Monthly water meter reading will help with compliance monitoring for individual customers.

8.10 WSCP Refinement Procedures
ͭͬͲͯͮ (a) (ͭͬ) Reevaluation and improvement procedures for systematically monitoring and evaluating the functionality of the water shortage contingency plan in order to ensure shortage risk tolerance is adequate and appropriate water shortage mitigation strategies are implemented as needed.
Per the requirements of CWC § ͭͬͲͯͮ(a)(ͭͬ), the WSCP includes a description of how the City will use the results of the monitoring and reporting to evaluate the need for revisions to the WSCP.
This WSCP is a dynamic tool that can be refined as needed to ensure that the shortage response actions are effective and are producing the desired results. Refinements or new actions may be identified and suggested by City staff, customers, or other interested parties. These suggestions will be evaluated by City administration for the possible incorporation into future revisions of the WSCP. If deemed necessary by City administration, these suggestions or revisions may be made to the current WSCP as an amendment so that they may be implemented quickly at the appropriate water shortage levels.
8.11 Special Water Feature Distinction
ͭͬͲͯͮ (b) For purposes of developing the water shortage contingency plan pursuant to subdivision (a), an urban water supplier shall analyze and define water features that are artificially supplied with water, including ponds, lakes, waterfalls, and fountains, separately from swimming pools and spas, as defined in subdivision (a) of Section ͭͭͱ͵ͮͭ of the Health and Safety Code.
Because pools and spas must use potable water for health and safety considerations, pools and spas are analyzed and defined separately in the WSCP from other water features which may use recycled water. Water features that are not pools or spas are distinguished in the WSCP with the use of terminology such as “decorative water features” or “recreational water features”, and shortage response actions, enforcement actions, and monitoring are prepared for each respectively.
8.12 Plan Adoption, Submittal, and Availability
ͭͬͲͯͮ(c) The urban water supplier shall make available the water shortage contingency plan prepared pursuant to this article to its customers and any city or county within which it provides water supplies no later than ͯͬ days after adoption of the water shortage contingency plan.
Chapter ͭͬ of this UWMP describes the process for adoption, submittal, and implementation of the UWMP. These same processes and steps will be followed for the adoption of the City’s WSCP. The City’s WCP currently serves as their WSCP per their municipal code and previous adoption and may be periodically amended independently of the UWMP as needed. The City shall follow their standard amendment process, public adoption hearings, issuance of notices to affected cities, counties, and the public about the adoption process, submittal to DWR, the California State Library, local libraries, and others. The City can also describe how the plan has been made available to all of the cities and counties it serves no later than ͯͬ days after it is adopted.

Chapter 9
DEMAND MANAGEMENT MEASURES
The UWMPA requires that the UWMP involve a comprehensive discussion of the agency’s water conservation measures.
10631 (f)(A)…The narrative shall describe the water demand management measure that the supplier plans to implement to achieve its water use targets pursuant to Section 10608.30. (B) The narrative pursuant to this paragraph shall include descriptions of the following water demand management measures:
(i) Water waste prevention ordinances
(ii) Metering
(iii) Conservation pricing
(iv) Public education and outreach
(v) Programs to assess and manage distribution system real loss (vi) Water conservation program coordination and staffing support. (vii) Other demand management measures that have a significant impact on water use as measured in gallons per capita per day, including innovative measure, if implemented.
This chapter presents details of the demand management measures (DMMs) contained in the UWMPA, as well as the City’s existing and planned efforts to further develop their water conservation program. The City is committed to water conservation and has implemented several policies and on-going programs that promote and encourage water conservation.
The UWMPA was amended in 2014 to streamline DMMs from 14 specific measures to 6 more general requirements and an "other" category. Brief descriptions of the City’s current and planned implementation of DMMs are included in the following sections.
9.1 Water Waste Prevention Ordinances
According to Section 25-32A.26 of the City Municipal Code, “the consumer shall use reasonable care to prevent the waste of water, shall not allow water to run or waste from his property onto streets or highways, shall not use water in washing sidewalks, building entrances or lobbies or other properties to such excess that water shall flow in street gutters beyond the frontage of properties occupied by them.”
CITY OF PORTERVILLE | 2020 URBAN WATER MANAGEMENT PLAN| CH 9 DEMAND MANAGEMENT MEASURES The City has a Water Conservation Plan (WCP) that serves as the City’sWSCP as discussed in Chapter 8. The City has seen positive reduction in water consumption as a result of thewater conservation plan. For example, as a result of the WCP implementation in the 2015UWMP, Figure 7.1 shows the City has seen steady conservation efforts from water usage over the last five years and reduced usage by 27 percent The WCP is implemented by a public hearing to discuss phase transitioning to Porterville City Council and then an official resolution by Council.
Any change in Phase of the WCP requires councilresolution.
For a number of years, theCity has been operating between Phase III and Phase IV of the WCP.
Phase III limits outdoor irrigation to twice a week and Phase IV to once a week. Typically, the City transitions to Phase III in May to allow 2-day watering during the summer months in order to maintain landscaping and will transition to 1-day watering schedules in December. In drier periods, the City tracks groundwater levels on a month to month basis and will recommend transitioning to WCP Phases earlier or later (e.g. 2 day watering schedule in late June and/or 1 day watering schedule inNovember) in the year to increase annual conservation efforts.
9.2 Metering
In 2020 theCity has approximately 98.5 percent of their water connectionsmetered. All metered customers are billed on a volumetric basis and therefore have incentives to conserve water and decrease monthly utility bills. The City continues to require water meters on all new connections for new development.
The City began adding water service meters to residents of East Porterville in 2016 and had a total of approximately 725 metered connections in 2020.The City tracks additional service connections separately in their water meter account.
The City is currently in theprocess of upgrading their water meter program to an advanced meter infrastructure (AMI) system which will create an integrated network that does not require physical efforts for meter data collection and will provide data to a City network at predetermined intervals.
9.3 Conservation Pricing
As of October 1
st
, 2020 theCity has updated their water rates to include a flat rate of $86.54, with a $19.89 minimum and an additional $1.91 per unit of water, where one (1) unit of water is equivalent to 100 cubic feet (748 gallons) of water. The City sewer rates are a flat rate of $26.87 per connection with commercial connections cost dependent on type of use. Phase VI of the City’sWCP includes a 20 percent water rate increase on all residential and landscape accounts to go into effect. This rate increase will encourage water conservation and will also service as a provision to recover the lost revenues from water conservation. Since the adoption of the WCP and with therevised WCP to account for the WSCP, the City has never implemented the 20 percent rate increase as a conservation measure.

CH 9 DEMAND MANAGEMENT MEASURES | 2020 URBAN WATER MANAGEMENT PLAN | CITY OF PORTERVILLE DRAFT FINAL| JANUARY 2022 | 9-3
The City municipal Code Section 25-32A.24 includes citations and fines are issued for noncompliance of the City’s water conservation regulations. Non-compliance with the City of Porterville’s water conservation regulations will result in one written warning from the City of Porterville before the issuance of a citation. A second violation within a 12-month period will result in the issuance of a citation with a fine of $100.00; a second citation will result in a fine of $200.00; a third citation will result in a fine of $500.00. Willful and egregious violations will result in issuance of a citation without a warning. Each day that a violation continues shall be regarded as a new and separate offense.
The City has continued to issue citations and fines since the implementation of the WCP since 2015 and plans to continuethis activity in the future.
9.4 Public Education and Outreach
Historically the City uses the following water conservation public information programs since 2015:
• City participation in Water Awareness Month (May).
• Bill stuffers on water conservation.
• News programs on local channels, change in WCP phases advertised as necessary. • Radio commercials in both English and Spanish.
• Booth at the Porterville City Fair and other city evens (Iris Festival etc.) • Water bills that compare current water usage to the previous year’s usage. • Facility tours of the City’s wastewater treatment plants for students. • Advertising through billboards, City transit vehicles, and flyers throughout City property.
The City plans to expand their public education and outreach efforts by including the following items:
• Social media outreach through the City Manager’s office. • Local Newspaper advertisements in addition to the WCP Phase changes. • Advertise on transit vehicles on the Greenpower bus fleet. • Local School district, interns, video shorts.
• City website advertisement.
• Mosquito abatement requirements and recommendations.
9.5 Programs to Assess and Mange Distribution System Real Loss DWR encourages agencies to detect and resolve leaks when economically feasible through reporting and audit mechanisms performed on water distribution systems. Water system audits include an evaluation of the City’s distribution system for leaks and other losses. System losses are quantified as water input minus metered and/or delivered water. The resultant loss is a good indication of a system’s integrity.
The City has performed water systems audits as required and are included in section Chapter 3 of this UWMP. The 2020 AWWA Water Audit is due October 2021.
CITY OF PORTERVILLE | 2020 URBAN WATER MANAGEMENT PLAN| CH 9 DEMAND MANAGEMENT MEASURES The City’s water distribution system is completely operated under pressure and as a result older pipes and facilities tend to develop leaks through deteriorated gaskets, seals, and developed cracks. As stated in the 2015 UWMP, a physical system audit is not performed every year, since the production to metered water use is fairly consistent. In all newly constructed water and sewer infrastructure, facilities shall be pressure tested prior to completion to identify any leaks to reduce and cost of physical water system audits.
City staff does perform individual water surveys on individual single and multi-family services at the request of owner. Typically these surveyors are requested when a customer feels their water bill is too high. A typical individual water survey includes the following:
1. Check indoor and outdoor plumbing for leaks.
2. Check irrigation system timers.
3. Evaluate Irrigation water schedule.
4. Flow tests for customer.
5. Recommend various water conservation measures to the customer, such as modifications to their irrigation schedule and retrofitting with water efficient fixtures and appliances.
Division 6 of the City’smunicipal code covers water conservation and efficiency measures required by the City. This section recognizes the importance of landscaped areas for the health of theCity; however themanagement of such areas shall be done in an efficient and water conscious methods to ensure theavailability of adequate supplies of water for futureuses.
As mentioned in Section 9.2, theCity is currently in the beginning stages of upgrading their existing water meter system to an AMI system. The AMI system will provide leak detection monitoring to notifyCity staff if a water meter is leaking or if a water system customer (residential, institutional, commercial, or industrial) has an onsite leak that can be fixed to both lower monthlywater bills and prevent waste.
9.6 Water Conservation Program Coordination and Staffing Support The City’s water conservation program is an ongoing program of public education and being proactive in continuousmonitoring,repairing, and managing the water supplies in conjunction with Stateregulations and surrounding agencies. The City also continues to monitorresidential, commercial and industrial customers through their metering program to ensure all entities in the water service area are complying with conservation measures to assure that thesystem will have adequate supplies in the future. The implementation of the entire program wide is theassumed responsibility of the City’swater superintendent, water systems specialist, and thepublic works director. This has been the case since theimplementation of the WCP in 2015 and the City continues to operate their water conservation program under this structure.
9.7 Other Demand Management Measures
The City does not have any additional demand management measures scheduled to be included in their City-wide water conservation program at this time. 9-4 | JANUARY 2022 | DRAFT FINAL

9.8 Planned Implementation to Achieve Water Use Targets The City plans on continuing to implement and manage it’s existing water conservation program as described in the previous sections throughout the foreseeable future. In summary, adding to the existing program, the City plans to implement the following programs as mentioned in the previous sections:
• Upgrade of their existing water meter system to an AMI system. • Significant increase in their public outreach and communication efforts. • Continued implementation of the WCP through City staff involvement and leadership from management level staff.

APPENDIX D CITY OF PORTERVILLE 2015 UWMP
PREFACE
The City of Porterville water system is municipally-owned with more than 15,299 service connections, 97% of which are metered, serving a population of 55,490, with approximately 1,100 service connections outside the city limits.
Water supplies for the City system are produced entirely from groundwater underlying the city, which is recharged from rainfall and runoff of the Western Sierra Nevada. The major stream contributing to the recharge of the Tule Basin Aquifer underlying Porterville is the Tule River.
Storage capacity represents over ten million gallons within the distribution system and five hillside reservoirs, three with a capacity of three million gallons, one with a capacity of three hundred and five thousand gallons, one with the capacity of five hundred and fifty thousand gallons.
A telemetry system controls the operation of 23 of the City's 35 active well pumps to maintain system pressure under varying loads. The water levels in the reservoirs are also monitored and controlled by the computerized telemetry control system.
Water conservation and awareness have always been areas of concern for the Porterville community. Less than normal rainfall and runoff makes efforts to promote water conservation a high priority. In addition to the benefits of conserving water as a limited natural resource, additional benefits accrue to the community in the form of a reduced impact on the Wastewater Treatment Plant and a reduction in energy costs when water supplies are conserved.
It is vitally important that the Water Conservation Plan be a joint partnership between the City and the General Public in order to achieve optimal effect. The Plan has been developed in five phases with each phase defined in terms of the available water supply.
APPENDIX D CITY OF PORTERVILLE 2015 UWMP
Actions within each phase have been defined as either actions to be undertaken by the City or by the General Public.
Due to the number of variables which affect the water conditions in existence at any one point in time, a City staff analysis of those variables will be utilized in determining the transition of the City from one phase to a more (or less) stringent phase. At such time as staff determines that water supply conditions warrant a phase change, staff will present the request to the City Council for their approval.
This plan differs from other valley community plans because the city of Porterville is in a more favorable position of having almost all of its water customers metered, which allows the City to basically control the water conservation program.
CITY WATER SYSTEM
The City has always been diligent in its efforts to provide sufficient safe and affordable drinking water to the residents of the community. Water conservation has long been a permanent part of the City’s water resource management program. Efforts to that end include:
NEW WELLS:
Over the past five years new wells have been added to the City water system in order to serve the needs of the community. Additional wells are planned for completion within the next few years. TELEMETRY SYSTEM:
This system controls the operation of the well pumps to maintain system pressure under varying loads. Water levels in the reservoirs are also monitored and controlled by the computerized telemetry control system. Water is usually pumped to the reservoirs during the off peak usage hours for later use by consumers. This system was designed to APPENDIX D CITY OF PORTERVILLE 2015 UWMP
operate the City wells in the most efficient and productive way possible with additional benefits of energy cost savings.
RESERVOIRS:
The City currently operates and maintains five (5) hillside reservoirs, three (3) with a capacity of three million gallons, one (1) with a capacity of 305,000 gallons, and one (1) with a capacity of 550,000. The three largest reservoirs are usually filled during off peak hours and then release water during the high usage hours. There is also a 300,000 gallon reservoir located at the Airport which is also part of the City system. The reservoirs increase the City’s ability to maintain system pressure during peak demand and fire flow situations. METERIZATION PROGRAM:
With over 97% of all service connections metered, the City has a goal of 100% meterization. All new connections are required to have meters.
UTILITY BILLING NOTICE:
The City's computerized utility billing system provides consumers with their current and past water usage history for comparison purposes. While variations may be attributable to a change known to the consumer (i.e. additional persons in the home, addition of a swimming pool), it may also be the result of an undetected leak or other controllable occurrence.
WATER AUDIT/LEAKAGE DETECTION & REPAIR PLAN:
The City will continue in its proactive plan to audit water supply usage. Upon detection of the source of any leakage, corrective action will be taken immediately in order to promote the efficient use of the existing water supply and in turn reduce the energy required to operate the system.
NEW WATER LINE TESTING:
The City requires full pressure and leak testing of all newly constructed water lines. FIRE HYDRANT TESTING:
The City Fire Department schedules their annual fire hydrant testing program during the early spring and late fall to avoid the peak water use season. Such testing is required to maintain the integrity of the fire protection system.
APPENDIX D CITY OF PORTERVILLE 2015 UWMP
CONSERVATION PHASING
The effectiveness of any voluntary plan ultimately depends on the public's awareness of the need for the plan. Local residents have a history of commitment to their community and support of the public welfare. It is a reliance upon this tradition that makes the distribution of public information the cornerstone of the City's Water Conservation Plan.
WATER CONSERVATION PHASE I: NORMAL WATER SUPPLY
The Water Conservation Phase I applies during periods when a normal water supply is available.
ACTIONS BY THE CITY:
Public Information Program Distribution of suggestions for residential, commercial, and industrial water conservation and awareness.
Coordination of public information with the local news media. City participation in Water Awareness Month (May).
Lawn and Landscape Watering Guides will be made available upon request.
City staff will coordinate with local nurseries to compile a list of low water using trees and plants. The list will be made available at City Hall, the Corporation Yard, and the Parks & Leisure Services Department for local residents.
Coordination with local schools to encourage young people to become aware of local water issues and conditions.
Advise against outdoor watering within forty-eight (48) hours of a measurable rainfall. Measurable rainfall is defined by the National Oceanic and Atmospheric Administration (NOAA) National Weather Service (NWS) as 1/100th of one inch.
Project Review Committee The City’s Project Review Committee (PRC) will include the evaluation of all submitted projects for water use and conservation efforts. The goal of City staff in cooperation with the developer will be to voluntarily reduce consumption of water used in the project. City staff will assist the developer in familiarization with the Xeriscape Concept, combining creative landscaping and efficient irrigation to save water and promote attractive alternatives to traditional, high water use landscapes.
City Landscapes and Watering Schedules City parks, median islands, and landscaped public facilities will be watered during late night or early morning hours to the greatest extent possible.
All new landscaping projects undertaken by the City will incorporate conservation design.
APPENDIX D CITY OF PORTERVILLE 2015 UWMP
Retrofit Bathroom Facilities Water saving kits which contain toilet water conservation and low flow shower head devices will be made available to City water consumers, both residential and commercial, upon request, as funds are available.
Fire Hydrant Testing The City's fire hydrant testing program will be scheduled during non-peak water usage times to the greatest extent possible without impairing the integrity of the City's fire protection service.
ACTIONS BY THE GENERAL PUBLIC:
Mindful Water Use The general public will be encouraged to utilize those water conservation measures contained within the City's Public Information Program.
Voluntary Odd/Even Watering Schedule This schedule is encouraged, but not mandated. This plan is designed to minimize water usage and requests that the public water their lawn and shrubs according to their street address, per Exhibit 1 below.
Addresses ending in an odd number (1, 3, 5, 7, or 9) water on Tuesday, Thursday, and Saturday. Addresses ending in an even number (0, 2, 4, 6, or 8) water on Wednesday, Friday, and Sunday.
There is no watering on Monday. Watering should be avoided between the hours of 5:00 AM to 10:00 AM and 5:00 PM to 10:00 PM.
Exhibit 1
APPENDIX D CITY OF PORTERVILLE 2015 UWMP
DROUGHT RESPONSE PHASE II: WATER SUPPLY SHORTAGE
Drought Response Phase II applies during periods when there is a water supply shortage. When water supply conditions start to deteriorate, the City is mandated to implement more stringent water conservation provisions for the benefit of its community. In addition to upholding the programs and provisions outlined in Phases I, the City must be diligent in its water conservation efforts by issuing penalties for non-compliance.
ACTIONS BY THE CITY:
Adoption and Enforcement of Stricter Water
Regulations and Restrictions
The City of Porterville will enforce an odd/even watering schedule for all residents. Watering is prohibited between the hours of 5:00 AM to 10:00 AM and 5:00 PM to 10:00 PM. Watering shall only occur on designated watering days. Excessive run-off is prohibited, as is outdoor watering within forty-eight (48) hours of a measurable rainfall. Measurable rainfall is defined by the National Oceanic and Atmospheric Administration (NOAA) National Weather Service (NWS) as 1/100th of one inch.
Per Section 25-5.1 of the City Municipal Code, Non-compliance with the City of Porterville’s water conservation regulations will result in one written warning from the City of Porterville before the issuance of a citation. A second violation within a 12 month period will result in the issuance of a citation with a fine of $100.00; a second citation will result in a fine of $200.00; a third citation will result in a fine of $500.00. Willful and egregious violations will result in issuance of a citation without a warning. Each day that a violation continues shall be regarded as a new and separate offense.
Per Section 25-5 of the City Municipal Code, “The consumer shall use reasonable care to prevent the waste of water, shall not allow water to run or waste from his property onto streets or highways, shall not use water in washing sidewalks, building entrances or lobbies or other properties to such excess that water shall flow in street gutters beyond the frontage of the properties occupied by them.”
Public Information Program The City will pursue a more aggressive distribution of information than its efforts initiated in the initial Water Conservation Phase to promote public awareness of the need to conserve water with a stronger emphasis on the water shortage condition.
Water System Pressure Reduction The City's water system may experience reduced water pressures during high usage periods. This may deter water use for nonessential activities and encourage scheduling of landscape watering to late nights or early mornings.
City Landscapes and Watering Schedules All City parks, median islands, and public facility landscapes will be watered during the late night or early morning hours to reduce impact on the water system during peak usage hours.
Leak Detection Water Waste The City will continue in its proactive plan to audit water supply usage. All City staff will be reminded of the necessity of reporting any evidence of APPENDIX D CITY OF PORTERVILLE 2015 UWMP
leaks or water waste for immediate action. There will be an emphasis on coordinated community efforts to reduce water waste.
“Waste of Water” Notices City staff will be equipped to issue “Waste of Water” notices to consumers identified as misusing water.
Mandatory Odd/Even Watering days Increase public education on the mandatory watering schedule program.
Public outreach will emphasize changes from the Water Conservation Phase I (Voluntary) to Phase II (Mandatory).

DROUGHT RISK ASSESSMENT
1.0 Purpose and Objectives
As part of the latest guidance under Water Code Section 10635(b), suppliers are required to prepare a Drought Risk Assessment (DRA) with descriptions of data and methods used, basis for supply shortage conditions, determination of the reliability of sources, and a comparison of the total water supplies and uses during the drought. The key sections of the DRA are a combination of sections from the Urban Water Management Plan (UWMP) and the Water Shortage Contingency Plan (WSCP). The DRA will be submitted every five years with the UWMP and will assist the City of Porterville with futureannual water supply and demand reporting. At this time, the California Department of Water Resources (DWR) has not established the annual reporting requirements.
The DRA contains the following:
1. New legislation that triggered the need for the DRA.
2. Water system overview, which includes a summary of the population, demand, and supply forecast through the year 2040.
3. Drought risk assessment and vulnerability considerations.
4. Response actions during supply shortage conditions.
5. Next steps.
2.0 New Legislation for Drought Resilience
As a result of the historic California drought from 2012 through 2016, Executive Order B-37-16 was issued by Governor Brown to establish a long-term framework for water conservation and drought planning. The initial framework to implement Executive Order B-37-16 was prepared in 2017 by DWR, the State Water Resources Control Board (State Water Board), the California Public Utilities Commission (CPUC), the California Department of Food and Agriculture (CDFA), and the California Energy Commission (CEC). It outlined actions that could be implemented by existing authorities as well new actions that could be expanded with a new legislature. The framework focused on using water more wisely, eliminating water waste, strengthening local drought resilience, and improving agricultural water use efficiency and drought planning. The framework also informed the development of Senate Bill (SB) 606 (Hertzberg) and Assembly Bill (AB) 1668 (Friedan) in 2018.
The key elements from the new legislation that impact the UWMP are eliminating water waste and strengthening local drought resilience. As part of the new requirements for strengthening local drought resilience, a DRA must be performed every 5-years in addition to conducting an annual water supply and demand assessment. The annual reporting will start in July 2022 and will include information relating to anticipated shortages, triggered actions, compliance and enforcement actions, and communication actions as outlined in the WSCP as outlined in Chapter 8.
An overview of the events that led to the new legislation is shown on Figure 1.

3.0 Water System Overview
The City’s water service area encompasses approximately 18.6 square miles, which includes, the airport, agricultural/conservation land in the south east and the limits of the City proper. The City is located in central California on the east side of the San Joaquin Valley. The City is adjacent to the Sequoia National Forest and the Sierra Nevada Foothills in Tulare County. Porterville is approximately 70 miles southeast of the City of Fresno and 50 miles north of the City of Bakersfield. The City’s service area climate is a semi-arid, Mediterranean environment with cold winters, warm summers, and moderate rainfall (11.6 inches/year average). Temperatures average mid 50’s in the winter and high 90’s in the summer months with peaks upward to 110 degrees Fahrenheit (oF).The City’s urban development boundary is primarily residential land use contributes approximately 60 percent of the total water demand with the remaining water demand made up by commercial, institutional, industrial, and landscape irrigation demands throughout the City.
The City’s water distribution system consists of approximately 258 miles of pipelines ranging in diameters from 4 to 16-inches, 36 active wells (2 of which are stand-by), and six active water storage tanks totaling 10.15 million gallons (MG).
3.1 Historical and Projected Population
The water service population from 2001 to 2010 was taken from the City’s 2015 UWMP. At the time, the growth rate was calculated at approximately 2.5 percent. As identified in the 2015 UWMP, the future growth rate from 2005 to 2020 is consistent over time and continues to be approximately 2.3 percent on average which is shown in Figure 2. The water service population from 2015 to 2018 was prepared by the 2020 Integrated Master Plan (IMP). The projected water service populations were calculated using a growth rate of 2.5 percent. The historical and projected population is shown in Figure 2. The water service population in 2020 is estimated at 77,692 from the City’s IMP. Table 1 shows the current and projected water service population for the City. The Porterville IMP shows a population of 127,307 at 2040 based on the 2020 water service population

(1) Growth rate set at 2.5 percent, consistent with City’s 2020 Integrated Master Plan.
3.2 Local Water Supply
The City drinking water supply is solely from groundwater extraction wells. The City’s groundwater supply is extracted using 36 active wells scattered throughout the water service area that pump directly into the water distribution system and surrounding above ground water storage tanks. Extracted groundwater is chlorinated at the wellheads to provide disinfectant residual in thedistribution system.
The City’s groundwater system is supplied from the east side of the Tule Sub-basin. The Tule sub-basin sits on a series of overlapping alluvial fan sedimentary deposits sourced from runoff from the Sierra Nevada mountain range east of the City.Near theCity, the natural waterways that promote supply to the groundwater basin are Deer Creek and the Tule River. Tule River flow is managed by Lake Success for flood control and recreation at Lake Success located just east of the City.The Sustainable Groundwater Management Act (SGMAclassifies groundwater basins into four various categories of prioritization (very low, low, medium, and high. Basins that are classified as medium or high priority are required to develop groundwater sustainability agencies (GSAs, develop groundwater sustainability plans (GSPs and manage groundwater for longterm sustainability. The Tule Subbasin is considered high priority basin within SGMA and the Eastern Tule Groundwater Sustainability Agency (ETGSAcompleted their GSP in 2019. DWR records indicate that the groundwater elevation is approximately 300 feet below ground surface. 4 | JANUARY 2022 | DRAFT FINAL

3.3 Existing and Projected Demands
The City’s water demand is primarily residential which consist of both single family and multifamily residential land uses. The City currently has a total of 17,063 water service connections with 97 percent of those connections metered. The 2020 water use was 3,647 MG (11,192 acrefeet [ac-ft]), this demand was approximately 1,200 MG less than what was projected in the 2015 UWMP. The City’s projected demands to 2040 are included in Table 2. The 2025 - 2040 demands take into consideration, population growth, development by land use within the City’s UDB, capital improvement developments, as well as consumer consumption behavior.

The supply and demand balance for the multi-dry year scenario considers the fluctuation in demands reacting to dry conditions in the first three years and then significantly reduce demands to reflect conservation efforts for the third, fourth, and fifth consecutive drought years.
It is assumed that the surface water allocations via the Friant-Kern Canal (FKC) are 100 percent the first year, 75 percent the second year, 50 percent the third year, and 25 percent the fourth and fifth years. As discussed, the City will meet their entire demand with groundwater.
3.4 Supply and Demand Balance
The City’s sustainable yield from the Tule groundwater basin is estimated to be 5,655 MG (17,355 acre-feet per year [AFY]). The City presently and historically meets all water demand, regardless of hydrologic conditions, with groundwater, however during periods of drought, the City does implement water conservation efforts in addition to passive savings from consumer behavior over the last five years. Table 3 lists the supply and demand balance under normal hydrologic conditions and utilizing conservative per capita demand estimates as indicated in the City’s IMP.

The supply and demand balance for the multi-dry year scenario is shown in Table 4. Chapter 7 of the UWMP describes in detail the demands for the consecutive dry-years in addition to the fluctuation in demand over the course of the period. Compared to Table 3, the groundwater recharge volume progressively decreases throughout the drought due in part to reduced annual surface water allocations to FKC contractors and the City, therefore available surface water for groundwater recharge is reduced.

3.5 Commitment to Water Use Efficiency
The City of Porterville has been successful at implementing conservation measures to reduce water use within their service area. Figure 3 shows the City’s per capita demand from 2000 to 2020. The City has reduced water demands by approximately 27 percent between 2010 and 2015 and have maintained an average 130 gallons per capita per day (gpcd) demand between 2015 and 2020. The most significant reduction in demand was between 2013 and 2015 from 179 gpcd to 130 gpcd.
Figure 3 Historical Per Capita Demand
Water conservation measures are included in the City’s existing water conservation plan (WCP) adopted in 2015. The WCP is included in Appendix I and the Water Shortage Contingency plan water shortage response actions are outlined in Chapter 8 of this UWMP. Chapter 8 crosswalks the five WCP water supply shortage levels to the six WSCP levels listed in Chapter 8. The WCP water use policies have been implemented in the recent past to prevent water waste and to encourage conservation measures throughout the City. The following water supply shortage response measures are included in theWSCP.
• Public Information Program:
- City staff organize and provide communication between public and City Council to effectively communicate water conservation phasing, awareness, landscape irrigation techniques, system changes, and coordination with City forces throughout each shortage response action.

CITY OF PORTERVILLE | 2020 URBAN WATER MANAGEMENT PLAN| DROUGHT RISK ASSESSMENT • Upgrade and Maintenance of Distribution System:
- Since the WCP was adopted in 2015, the City has installed additional new wells to augment the water supply in order to meet drought demands. The continually monitors, well pump pressure and flow and water storage reservoir volumes to operate the City wells in the most efficient and productive way possible with additional benefits of energy cost savings. Additionally, the City has continued to upgrade its water distribution system with the recent completion of capital improvement plan.
• Conservation Measures:
- The most effective conservation measure the City utilizes is their water meter program. The majority of the City’s water services are metered and all new water service connections are required to be metered. As water shortage response actions of the WSCP are implemented, watering schedules are implemented to promote effective landscape irrigation for City parks, median islands, landscaped public facilities. Additionally, landscape irrigation schedules are implemented for residents based on even/odd addresses. Stricter conservation efforts prohibit ornamental water features, vehicle washing, sidewalk hosing is restricted. For the Critical water supply shortage, the City implements a 20 percent rate increase on all residential and landscape water service accounts. This increase both encourages water conservation as well as serves as a mean to recover loss revenues from water conservation.
• Water Audit/Leakage Detection and Repair Plan:
- The City continues a proactive to audit water supply usage. Upon detection of any leakage, corrective action is immediately taken by City forces. This promotes efficient use of the existing water supply, protects the distribution system components, maintains the water quality, and reduces energy to operate the system. As new water lines are installed, the City requires full pressure and leak testing of all newly constructed water lines.
4.0 Drought Risk Assessment
4.1 Five-Year Drought Risk Assessment
A summary ofthe City’swater supply drought risk assessment from 2021 through 2025 is summarized in Table 5. The City presently and historically has met all of their demands from groundwater and actively uses surface water allocations for groundwater recharge throughout the year. Groundwater recharge is not assumed to be a WSCP planned action since it’s the City’s status quo.Additionally, the City is still well below their sustainable yield value as indicated in the ETGSP therefore, there is sufficient supply to meet projected demands within the next five years.

CITY OF PORTERVILLE | 2020 URBAN WATER MANAGEMENT PLAN| DROUGHT RISK ASSESSMENT 10 | JANUARY 2022 | DRAFT FINAL
4.2 Drought and Water Shortage Risk and Vulnerability Assessment Water Code Division 6 Part 2.55 Section 8 Chapter 10 (Assembly Bill 1668) requires DWR, in consultation with other agencies and an advisory group, to identify small water suppliers and rural communities that are at risk of drought and water shortage. DWR defines the City of Porterville as a rural community that is self-supplied since its supply is solely from groundwater.
This assessment is the first statewide effort to systematically consider water shortage risks to rural communities and should be continuously observed as better datasets and scoring methods become available. Findings are to be shared within counties, GSA’s, the public, and other relevant regional groups.
Using the rural community risk scores public dataset provided by DWR, Porterville was examined and received a numeric risk score, which is derived from a set of indicators developed from a stakeholder process. Indicators include five components relating to risk of drought and water shortage vulnerability. These five components are classified into three general categories representing vulnerability, as seen in Figure 4 and discussed below. The output risk score ranges from 0 to 100, where 100 is the highest risk. This is a rescaled risk score, which means that all numeric scores are relative to the other communities examined in California.
4.2.1 Exposure to Hazard
As defined by DWR for the dataset provided,
exposure represents the degree to which a
water supplier’s service area and/or a
community is exposed to various hazardous
environmental conditions and events that could
lead to drought and/or water shortage. The risk
scoring includes the likelihood of the intensity,
severity, duration, and frequency for water
shortage and drought in a given location. For
the purpose of this DRA, this includes risks
based on modeled future projections with
climate change impacts (Risk Component 1,
RC1) and recent hazardous conditions and
events (Risk Component 2, RC2).Appendix A provides a detailed description and score specifically for Porterville for each risk indicator listed below:
• Climate change vulnerability uses three primary risk factors as indicators for scoring:
- Temperature Shift: Projected change in heat by mid century - Wildfire: Projected severe or high sever risk for each system boundary or community
- Saline Intrusion Risk: Susceptibility to sweater intrusion • Recent hazardous conditions and events use ten primary risk factors as indicators for scoring:
- Drought Early Warning: Annual updated early drought risk warning. - Wildfire Risk: Modelled current risk maximum for each census block group. - Fractured Rock Area: Fractured rock area (within the groundwater basin). - Population Growth: Projected population growth
Figure 4 Grouping of Risk Indicators
DROUGHT RISK ASSESSMENT | 2020 URBAN WATER MANAGEMENT PLAN | CITY OF PORTERVILLE DRAFT FINAL | JANUARY 2022| 11
- Water Quality Index: Domestic well water quality risk (includes areas outside of alluvial basins).
- Subsidence Presence: Record of subsidence.
- Salt Presence: Record of salts in groundwater basin.
- Over drafted Basin: Critically over drafted groundwater basin. - Declining Water Levels: Declining groundwater levels. - Surrounding Irrigated Agriculture: Presence of irrigated agriculture in surrounding basin.
The City of Porterville Scored a 26 for climate change vulnerability, RC1, which is equivalent to the average score for rural communities. The City scored a Recent Hazardous Conditions Score, RC2, of 47 which is just slightly below the statewide average score of 48.
4.2.2 Vulnerability
As defined by DWR for the dataset provided, vulnerability is the propensity or predisposition to be adversely affected. Such predisposition constitutes an internal characteristic of the affected element, whereas exposure to a hazard is a condition or event to which the affected element (i.e., a water supplier) is subjected. Vulnerability is quantified by a series of social and physical factors as they relate to groups of self-supplied residences. These groupings spatially are represented by US Census Block Groups. As done for the small water supplier vulnerability, selfsupplied community vulnerability is quantified using (Risk Component 3, RC3) physical and (Risk Component 4, RC4) organizational vulnerability factors.
Self-supplied community vulnerability uses two risk indicators for scoring:
• Well Depth Flag: Portion of groundwater unit(s) that intersect with the census block group have relative shallow domestic wells.
• Well Depth Proportion: Proportion of Public Lands Survey Sections in block group where the max depth of domestic wells is 10 percent of more shallow than max of public wells.
Organizational vulnerability is a single aggregate indicator including 14 separate indicators, which are listed in Appendix A with description and individual average score. This risk indicator in summary considers demographic variables, population characteristics including age, residence type, income, and education.
The City did not receive a score for the self-supplied community vulnerability which represents the City’s wells are not considered shallow with respect to the Census Block Group. Additionally, the City provides water to most areas within their water service area. The statewide average for self-supplied community vulnerability is 87. The City’s organization vulnerability risk score is 77 whereas the statewide average score is 45.
4.2.3 Water Shortage Record
Recent history of shortage and drought impacts are incorporated into the vulnerability assessment (Risk Component 5, RC5), which include risk indicators of reported household outages in domestic wells and private wells. Records of these recent outages are kept by the State and managed by DWR. This is used to identify vulnerable areas that are prone to repeat outages due to well level fluctuation or other sensitivities.
CITY OF PORTERVILLE | 2020 URBAN WATER MANAGEMENT PLAN| DROUGHT RISK ASSESSMENT Water Shortage Record vulnerability uses two risk indicators for scoring:
• Reported Household Outages on Domestic Wells: Presence of one or more households with reported outages (supplies from domestic well) in Census Block Group. • Reported Household outages on Private Well: Proportion of households with reported outages (supplied from private well) in Census Block Group.
The average score for water shortage record vulnerability for self-supplied communities is 81, whereas the City scored a 56.
4.2.4 Drought and Water Shortage Risk Score
Calculations provided in the public dataset for risk scores and indicators are in accordance with California Water Code Section 10609.42 and completed through a stakeholder evaluation process between the years 2018 and 2020. Approximately 5,000 Census Block Groups were analyzed for the method of aggregation for scoring communities. For each selection, variables or components were rescaled between 0 and 100 then combined using the equation provided in Appendix A. Scores are then calculated for each component and added together, allowing for identification of the risk level and weight of risk factors. Additional details regarding the risk scoring and methodology used to assess the BBLDWP service area are located in Appendix A.
A total of eleven census blocks or “geoids” were identified in the rural and self-supplied communities’ dataset that include City’s service area. These eleven geoids were averaged to provide a summary of each component representing the City’s system and are as follows:
• Score RC1: 26 = Exposure to climate change.
• Score RC2: 47 = Exposure to recent hazardous conditions and episodic events. • Score RC3: 0 = Physical vulnerability.
• Score RC4: 77 = Organizational vulnerability.
• Score RC5: 56 = Record of drought impacts.
The final risk score assessed for all five components equated to 60.4 out of 100 for Porterville.
This score is above average the rural and self-supplied communities final score of 41.8. This demonstrates that the City is considered to have a higher-than-normal drought and water shortage risk.
4.3 Climate Change Considerations
Cal-Adapt Extended Drought tool displays hydrologic data projected to specific date ranges of this upcoming century. Early Century is considered 2023 to 2042 and late century 2051 to 2070.
This tool explores data for two 20-year drought scenarios, earlier and latter part of thecentury, derived from meteorological and hydrological simulations. Cal Adapt includes projected max/min temperatures, precipitation, evapotranspiration, snow water equivalent, and runoff values for a period of an extended drought period of up to 20 years Data from the Cal-Adapt Extended Drought Tool was analyzed to summarize the potential impacts on water supplies related to climate change with respect to historical data. Asummary of the tool outputs is summarized in Table 6 below.
As mentioned, theCity and much of theCalifornia Central Valley is completely reliant upon groundwater from the Tule subbasin for its drinking water supply. The California Water Resiliency Portfolio summaries the effects of climatechange on these supplies as listed below:
12 | JANUARY 2022 | DRAFT FINAL
DROUGHT RISK ASSESSMENT | 2020 URBAN WATER MANAGEMENT PLAN | CITY OF PORTERVILLE DRAFT FINAL | JANUARY 2022| 13
• Rising winter temperature will reduce mountain snowpack in the Sierra Nevada mountain range, thus reducing spring/summer runoff and increasing winter floods. • Increasing temperatures will mean higher risk of wildfire to fire-prone areas, decreasing watershed health and habitat thus reducing water runoff quality in reservoirs, streams, and rivers.
• Increased frequency and intensity of periods of drought. • Stresses on existing infrastructure may not meet supply expectations of communities and agriculture.
• Current health of natural ecosystems tends to force species to migration potentially affecting other habitats.
• Increased demand with decreasing supplies from both population and economic growth.
Maximum temperatures are shown to increase approximately 5.8 percent and 9.8 percent from the observed historical for both the early and late century drought conditions, respectively. The precipitation depth is shown to decrease approximately 43 to 45 percent for the entire extended drought condition, therefore reduce runoff between 48 percent to 59 percent between both the early and late drought conditions, respectively. The snow water equivalent is 0-inches since it rarely snows in Porterville, therefore this is not a measured value.

4.4 Seismic Risk Assessment and Mitigation Plan
The City of Porterville is included in the Tulare County Multi-Jurisdictional Local Hazard Mitigation Plan (MJLHMP). Chapter 7 describes in detail the mitigation actions and goals the County is striving towards specifically for earthquake hazards. The entire County MJLHMP is included in Appendix L of the UWMP for reference.
5.0 Water Shortage Response Action
The City municipal code section 25-32A.27: City Water Conservation Plan states, “The City’s Water Conservation Plan is deemed to be the City’s “water shortage contingency plan” as per applicable state law”. As discussed in Chapter 8 of this UWMP, the City’s current WCP five water supply shortage levels correspond to the six water shortage levels outlined in the water code by a crosswalk authorized by Water Code Section 10632(a)(3)(B). Therefore, the City’s WCP levels are further expanded to meet the DWR guidelines and provide water shortage response actions to the six levels identified in the water code.
CITY OF PORTERVILLE | 2020 URBAN WATER MANAGEMENT PLAN| DROUGHT RISK ASSESSMENT 14 | JANUARY 2022 | DRAFT FINAL
The goal of water shortage response actions outlined in Chapter 8 are to have a procedure for managing and mitigating shortages that allow the City to adequately respond in an efficient and effective manner. A summary of the shortage levels and response actions are included in Chapter 8 of this UWMP. If there is a shortfall of supply while performing the drought risk assessment, the City should consult the water shortage response actions to use as a baseline to identify possible water conservation measures to mitigate supply shortages.
6.0 Conclusion and Recommended Next Steps
The City’s DRA outlines the performance of the City’s water supply during multiple hydrologic conditions; normal, single-dry, and multi-dry year period. It’s concluded that the City has sufficient supplies to meet the anticipated demands to the year 2040. Using the dataset provided by the DWR to assess the City’s vulnerability for rural and self-supplied communities, Porterville is considered as an above average risk for drought and water shortage when compared to other water supplies statewide. The City continues to diligently secure and expand future groundwater augmentation supplies in the near future to meet anticipated demand and continues to investigate diverse water supplies to diversify their supply portfolio.
As part of the new 2018 legislation for UWMPs, annual water shortage reporting will be required starting July 2022. Therefore, the information listed in Table 5 should be reviewed, updated, and revised on an annual basis and for significant changes in the City’s water system supply and demand.

Item No. 6.
CITY COUNCIL AGENDA – MARCH 1, 2022
SUBJECT: Consideration of the Brookside Subdivision Project SOURCE: Community Development
BACKGROUND: The City of Porterville Project Review committee began its assessment of PRC 2020-44 on December 16, 2020. Subsequently, PRC 2020-44 was also discussed at the PRC meeting on March 24, 2021. The project consists of several development entitlements: an amendment to the General Plan Land Use Diagram, a change of prezoning, a conditional use permit, a tentative subdivision map, and annexation. The project, if approved, would result in the annexation and development of a portion of approximately
56.06 acres of APN 245-010-087 located southeast of the Friant-Kern Canal (FKC). APN 245-010-092 (Summit Charter Academy) and APNs 245-010-037 & 041 (rural residences) would also be annexed. The overall project site is largely bounded by Westwood Street, Westfield Avenue, Lombardi Street, the Friant-Kern Canal (FKC), and the Castle Avenue alignment. Development of the project site generally includes subdivision of APN 245-010-087 into 229 lots for single-family use, construction of a
2.99-acre park, construction of interior local streets and necessary onsite infrastructure, and improvements within abutting major street rights-ofway. The annexation area totals approximately 69.65 acres.
The parcels are currently identified in the 2030 General Plan Land Use Element as a variety of land uses: Low Density Residential, Medium Density Residential, Neighborhood Commercial, Parks and Recreation, and Education. The project area is currently zoned AE-20 (Exclusive Agriculture, 20-Acre Minimum) by the County of Tulare and prezoned RS1 (Very Low Density Residential) by the City of Porterville. The site is also within a Residential Neighborhood Center, to which the Residential Neighborhood Zone District might normally apply if the project were to proceed in accordance with the existing General Planned Land Uses. Since the project includes an amendment to the General Plan, and implementation of a Residential Neighborhood Plan is optional in any case, the provisions of the RN District will not apply.
COMMENT: To facilitate the project, the applicant has proposed to amend the General Plan Land Use and prezoning as follows:

The proposed tentative subdivision map would provide new single-family residential housing on lots ranging from 5,000 SF to 12,000 SF. Circulation is provided through the planned internal streets, which include parkway strips, streetlights, and sidewalks. The subdivision provides external connections to Westwood Street, Westfield Avenue, and Lombardi Street, as well as to the existing private street along the southern property line of Summit Charter Academy. Longer blocks within the subdivision are broken by paseos to enhance pedestrian connectivity. In order to meet the requirement for park space, the project includes a centrally-located park of
2.99 acres, which will be improved prior to dedication to the City and included in the Lighting and Landscape Maintenance District. The project will also dedicate a well site.
ANALYSIS: The project’s 229 single-family dwellings provide a development density of approximately 4.08 units per acre, well below the maximum of 6.0 units per acre allowed in the Low Density Residential Land Use designation. The areas to the west, south, and east of the site are already developed with single-family residences. The project, while proposing lots with a smaller minimum size than the existing surrounding neighborhoods, still results in a development pattern that is compatible with the area and that falls within the prescribed density mandated by the General Plan. For reference, the four proximal subdivisions—Orchard Ridge, Williams Ranch, North Creek, and Porter Creek—have built-out densities of 4.32, 3.75, 3.81, and 3.78 Item No. 6.
units per acre, respectively, with a total of 586 lots on 149.12 acres. If Brookside were built at the average density of the surrounding projects (3.92 u/a), that would equate to a 219-lot project, which is not significantly lower than the 229 lots proposed. If the site were developed consistent with the existing General Plan land uses, it would support as many as 336 dwellings in a mix of single- and multifamily development along with up to 41,000 square feet of commercial space. While the amended land use and zoning would provide the opportunity for a similar number of units (339), the project as proposed by the applicant results in a less intensive, and therefore likely less impactful, project than what would be permitted without the proposed land use and zoning changes. Further, depending upon the specific multifamily and commercial uses proposed, it is likely that the development would not be subject to discretionary review or, therefore, CEQA.
Prior to approval of any amendment to a General Plan, Government Code Section 65352.2 requires that the City notify any California Native American Tribe identified by the California Native American Heritage Commission (NAHC) as having an historical or cultural affiliation with the area and provides those Tribes 90 days to comment on the proposal.
Following receipt of a Tribal contact list from NAHC, the City notified nine Tribal contacts about the project between May 14, 2021 and May 24, 2021 to solicit comments. No comments were received.
The RS-2 zone has a minimum lot size of 6,000 SF. To facilitate a slightly smaller minimum lot size of 5,000 SF (with a corresponding minimum width of 50 feet), the project proposes a conditional use permit (CUP).
Development Code Section 201.4(C) provides that an applicant may request a lot size as low as 3,000 SF subject to City Council approval of a CUP, if it finds that the lot size and configuration are consistent with the General Plan and will not adversely affect adjoining uses. This project is not requesting lots of that size. Additional design elements, including but not limited to enhanced street trees and varied lot widths along with optional elements such as traffic calming facilities and park space are required, and the project includes them. As described above, the project would fall within the prescribed General Plan density and is not out of character with surrounding development. Prior to approval of a conditional use permit, the Council must make the following findings pursuant to Development Code Section 604.04:
Approval of the proposed project will advance the goals and objectives of and is consistent with the policies of the general plan and any other applicable plan that the city has adopted. Following amendment of the General Plan as proposed, the project will result in development at a density consistent with the provisions of the Low Density Residential designation.
The project will serve to implement Policies LU-G-6, LU-G-7, LU-G-9, LU-G-10, LU-I-13, LU-I-14, LU-I-15,LU-I-18, LU-I-19, LU-G-17, and LU-G-19. There are no other applicable plans.
Item No. 6.
The location, size, design, and operating characteristics of the proposed project are consistent with the purposes of the district where it is located and conforms in all significant respects with the general plan, this development ordinance and with any other applicable plan adopted by the city council. The characteristics of the project are compatible with the standards of the RS-2 district (as modified by this conditional use permit).
The development conforms to the density of the Low Density Residential designation and serves to implement numerous policies of the General Plan.
There are no other applicable plans.
The California Subdivision Map Act (Government Code Section 66410, et seq.) establishes most of the procedures for subdivision of land. Other components are contained within Series 400 (Land Division) of the Porterville Development Ordinance. Generally, a tentative and final map are required in order to subdivide land into five or more parcels. Pursuant to both the Map Act and Series 400, tentative maps are valid for 24 months following approval, with various mechanisms available to extend the life of the tentative map. Subject to approval of the conditional use permit allowing lots with a minimum size of 5,000 and minimum width of 50 feet, all lots within the subdivision comply with area, width, and depth requirements. The project would be responsible for the dedication and improvement of the abutting major streets along with payment of specified fair-share costs to other capital improvements (signalization, transit stop) and development impact fees as applicable. The project is illustrated in two phases, although the Map Act precludes the City from requiring or disallowing phasing and from dictating the configuration of any proposed phases. The City can, however, impose reasonable conditions upon phases that are proposed.
Pursuant to Development Code Section 400.04, the City Council must deny a tentative map if it makes any of the following findings:
1) That the proposed map is not consistent with applicable general and specific plans. Most of the project site is designated Low Density Residential, which has a maximum density of 6.00 units per acre. The project proposes to amend the General Plan Land Use for the remainder of the site to Low Density Residential as well. The tentative map proposes 229 single-family residential lots on 56.06 acres for a density of 4.08 units per acre and therefore is consistent with the General Plan as proposed for amendment. There is no applicable specific plan.
2) That the design or improvement of the proposed subdivision is not consistent with applicable general and specific plans. The design and improvement of the project are in accordance with the Circulation Element of the General Plan as well as with the development standards contained within the Development Code, which is itself the primary tool for implementation of the General Plan. There is no applicable specific plan. 3) That the site is not physically suitable for the type of development.
Item No. 6.
The site is generally flat and level, making it physically optimal for the development as proposed.
4) That the site is not physically suitable for the proposed density of development. The site is generally flat and level, making it physically optimal for the development as proposed.
5) That the design of the subdivisions or the proposed improvements is likely to cause substantial environmental damage or substantially and unavoidably injure fish or wildlife or their habitat. An environmental impact report was prepared for the project. With inclusion of mitigation, the project will not result in any significant effects to the environment or to fish or wildlife or their habitat.
6) That the design of the subdivision or type of improvements is likely to cause serious public health problems. An environmental impact report was prepared for the project. With inclusion of mitigation, the project will not result in any serious public health problems.
7) That the design of the subdivision or the type of improvements will conflict with easements, acquired by the public at large, for access through or use of property within the proposed subdivision. With the possible exception of easements dedicated for major street right-of-way, which will be further dedicated and improved for the benefit of the public at large, there are no easements for access through or use of the property.
Based on a fair reading of the record, including the environmental impact report (described in further detail below), there is no indication that any of the findings requiring denial of the tentative map can be made.
As previously described, the project site is not within the city limits.
However, Government Code Section 66454 allows the City to approve a tentative map on land outside the city limits with the provision that the final map cannot be approved until annexation of the site is complete.
Annexation would require action by the Tulare County Local Agency Formation Commission (LAFCo).
The proposed land division and subsequent development of the site into a residential subdivision will provide needed housing in conformance with the City’s General Plan Land Use and Housing Elements, as well as to help meet our Regional Housing Needs Allocation quota. Staff and the applicants' agents have worked through the design details to ensure adherence to the General Plan and Development Ordinance, as well as to ensure compliance with the Map Act and applicable codes.
In addition to enhanced notification provided related to CEQA (see below), public notice of this hearing was provided in accordance with Government Code Sections 65090 and 65091 and Development Code Section 609.06.
The procedures prescribed therein are the standard for hearings involving amendments to the General Plan or zoning and for conditional use permits Item No. 6.
and tentative maps. Additionally, as described in the Background section above, this project was the subject of two Project Review Committee meetings over the span of several months. Information regarding PRC is readily available on the City’s website: PRC meetings are held on a regular basis, are agendized, and are accessible to the public.
ENVIRONMENTAL
REVIEW:
During early review of the project, the City contracted with Crawford & Bowen Planning, Inc. to prepare an initial study (IS) to analyze the potential for environmental effects that could result from the project. Pending the results of technical studies being prepared in conjunction with the IS, the City made the determination that an environmental impact report (EIR) would be required. On July 9, 2021 the City issued a notice of preparation (NOP) of an environmental impact report indicating a comment period starting on July 10, 2021 and ending on August 9, 2021. Along with the IS, which identified the potential for impacts to Biological Resources and Cultural Resources (and included relevant mitigation), the NOP identified the potential for impacts in the areas of Air Quality, Greenhouse Gas Emissions, Energy Resources, and Transportation. The NOP was provided to several public agencies as well as to the owners of real property within 500 feet of the project site, and a duly noticed scoping meeting was conducted on July 27, 2021. Several comments were received in response to the NOP.
Upon completion of the Draft EIR, the notices of availability and completion were filed in accordance with CEQA. Again, owners of property within 500 feet of the project site were notified of the availability of the document. The Draft EIR was circulated for a period of 45 days starting on November 6, 2021, and ending on December 21, 2021. As circulated, the Draft EIR addressed impacts to Air Quality, Biological Resources, Cultural Resources, Greenhouse Gas Emissions, and Transportation; the project was determined to not have a potentially significant effect in the area of Energy Resources and no mitigation was required. For the other resource categories, mitigation was identified that would reduce all potentially significant effects to a less-than-significant level (i.e., no significant and unavoidable impacts were identified). Several comments were received: some in writing (including email) and some orally as part of unscheduled communication at City Council meetings. As required under CEQA, the City has provided formal responses to all comments received; the comments and their responses are a mandatory component of the Final EIR. All parties submitting comments were provided either printed or electronic copies (at their discretion) of the Final EIR at least 10 days prior to this hearing (The City is not required to provide the Final EIR to private entities, only to public agencies). As a result of the comments received, minor clarifications and revisions were made to the EIR. Most importantly, certain comments appropriately requested that the traffic impact study be revised to account for increased in-person attendance at Summit Charter Academy commensurate with the relaxing of COVID-19-based restrictions; this resulted in preparation of an Item No. 6.
addendum letter to the traffic impact study. Of note is that, while the existing conditions were identified as being noticeably worse than originally identified in the traffic study, the addendum did not result in any changes to the required mitigation or to the level of impact following that mitigation.
A common theme throughout many of the comments was that there exists an untenable traffic situation, both near the project site and at other locations in the vicinity. It appears that there may be a misconception among some of the commenters that a development project can be held responsible to correct or mitigate an existing situation. On the contrary, a project can only be required to mitigate the impacts, or effects that it causes.
Conditions of approval, whether specifically put in place as part of CEQA or tied to a separate component of project approval, must both be linked to (i.e. the essential nexus) and commensurate (roughly proportional) with the effects the project causes. In this case, the project obviously did not cause the existing traffic situations on (for example) Lombardi Street near Summit Charter Academy or at the Westwood Street crossing of the Porter Slough. The traffic impact study (and its addendum) did not identify sufficient traffic from the project at the Westwood crossing to require mitigation at that facility. Similarly, there is no indication that the project results in the need to construct Castle Avenue to the northeast as a point of connection to Lombardi Street. While completion of Castle Avenue would likely alleviate traffic congestion in the vicinity of the project, there is no established connection (or nexus) between the project itself and the need to construct Castle Avenue. The study did, however, identify sufficient effects at the intersection of Lombardi Street and Westfield Avenue to require mitigation in the form of payment of fair-share costs (41.19% of the cost) of signalizing that intersection. Fair-share costs for two other intersections are also included. For this reason, to the extent the project would have otherwise made the existing problem worse, it will have mitigated its own impacts and met its obligations under CEQA.
RECOMMENDATION: That the City Council hold the public hearing to receive comments on the Brookside-Laurelwood Development Project, and then:
1. Adopt the Draft Resolution certifying the EIR and adopting the mitigation monitoring and reporting program;
2. Adopt the Draft Resolution amending the General Plan to reflect the Land Use designation of the site as Low Density Residential;
3. Introduce and waive the first reading of the Draft Ordinance, prezoning the respective portions of the site to the RS-2 Low Density Residential District and the PS Public and Semi-Public District;
4. Adopt Draft Resolution approving the conditional use permit;
5. Adopt Draft Resolution approving the tentative subdivision Item No. 6.

Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 1 CHAPTER ONE - Introduction
Introduction
This Final Environmental Impact Report (EIR) contains the public and agency comments received during the public review period for the Lombardi Development Project (proposed Project) and responses to each of those comments.
This EIR is an informational document intended to disclose to the decision makers of the City of Porterville (City) and the public the environmental consequences of approving and implementing the Lombardi Development Project or one of the alternatives to the proposed Project, which are described in the Draft EIR. All written comments received during the public review period (November 6, 2021, through December 21, 2021) of the Draft EIR along with transcriptions of oral comments received at the December 7, 2021 City Council meeting are addressed in this Final EIR.
The responses in the Final EIR clarify, correct, and/or amplify text in the Draft EIR. Also included in the Final EIR are minor text changes made at the initiative of the City (the Lead Agency) and in response to comments. The Final EIR was prepared in accordance with the California Environmental Quality Act (CEQA; Public Resources Code Sections 21000, et seq.) and the State CEQA Guidelines (Code of Regulations Title 14, Chapter 3, Section 15000, et seq.).
Project Description
The proposed Project consists of an Annexation, General Plan Amendment, Rezone and a Tentative Subdivision Map to allow for the construction of up to 230 single-family residential units. Parcels to be annexed include 245-010-087, -092, -037 and -041 for a total of approximately
69.65 acres. The 56-acre subdivision would be developed on Assessor Parcel Number 245-010- 087. The Project site is located between N. Westwood Street and N. Lombardi Street, bounded to the south by W. Westfield Avenue. Specifically, Project components include:
• Construction of up to 230 single family residential units. • Development of a 130,244 square foot park in the center of the residential development. • Construction of local roads with five points of ingress/egress; one on the southern boundary of the property off W. Westfield Avenue, one on the western boundary off N.
Westwood Street, one on the northern boundary off an unnamed street adjacent to the Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 2 Summit Charter Academy, Lombardi Campus, and two on the eastern boundary off N.
Lombardi Street.
• Improvement of all streets in or adjacent to the subdivision, in accordance with the approved improvements plan, per Section 407.02(h) of the Porterville Development Ordinance.
• Development of a subdivision tree and landscaping design that will be approved by the City. At least one tree will be planted on each residential lot and street trees will be planted at 35 feet on center along all parkways within and/or bordering the subdivision. • Development of a Landscape plan, in accordance with Chapter 303 of the Porterville Development Ordinance.
• Change the zone on APN 245-010-087 from the prezoned RS-1 to RS-2 (Very Low Density Residential to Low Density Residential).
• Annexation of APNs 245-010-087 (56.32 acres), -041 (1.00 acre), -037 (1.06 acres) and -092 (11.27 acres). Summit Charter Academy, Lombardi Campus, is on APN 245-010-087, and rural houses are on -037 and -041. Aside from construction of public improvements (curb, gutter, and sidewalk improvements) within existing and proposed rights-of-way, the only physical changes proposed with this Project will occur on APN 245-010-087. • Cancellation of Williamson Act contract Number 05126 and disestablishment of Ag Preserve 2034
Upon Annexation, General Plan Amendment to change the land use designation, and Rezone, the proposed Project would be in be within city limits and compliant with land use requirements.
Water, sewage disposal, and refuse collection services will be provided by the City of Portville and the applicant will be required to connect to the City’s existing facilities. The proposed Project would require gas, telephone, cable, and electrical improvements. Natural gas would be provided by The Gas Company; telephone services would be provided by AT&T; electric power would be provided by Southern California Edison Company; and cable television would be provided by Charter Communication. The extent of work required for utilities and gas would be determined during final project design.
Project Location
The City of Porterville is located in Tulare County in the southern part of the San Joaquin Valley.
The approximately 69.65-acre Project site is located in northwest Porterville, bounded to the west by N. Westwood Street, to the south by W. Westfield Avenue, and to the east by N. Lombardi Street. Residential subdivisions lie to the west, east, and south. Summit Charter Academy, Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 3 Lombardi Campus lies directly north, with a diagonal of the Friant-Kern Canal along the northwest corner. See Figure 1. Porterville is bisected north-south by State Route (SR) 65 and SR 190 runs east-west in the southern portion of the City.
The proposed Project site is currently in use with primarily agricultural activities. Two rural residences associated with the agricultural activities reside in the Project area; one along W.
Westfield Avenue and one along N. Lombardi Street. Both residences are adjacent to vacant areas utilized for storage and staging heavy equipment.
Project Objectives
The following are the primary goals of the City of Porterville’s Lombardi Development Project (Project):
• To provide housing opportunities with a range of densities, styles, sizes and values that will be designed to satisfy existing and future demand for quality housing in the area. • To provide a sense of community and walkability within the development through the use of street patterns, a park, landscaping and other project amenities. • To provide a residential development that is compatible with surrounding land uses and is near major services.
• To provide an economically feasible residential development that assists the City in meeting its General Plan and Housing Element requirements and objectives.
Summary of Environmental Impacts
As described in Chapter 3 of the Draft EIR, it was determined that all impacts were either less than significant or could be mitigated to a less than significant level. Mitigation measures are listed in Chapter Four – Mitigation Monitoring and Reporting Program of this Final EIR.
Background
Notice of Preparation
In accordance with CEQA Guidelines Section 15082, the City released a Notice of Preparation (NOP) on July 10, 2021 for a review period that closed on August 9, 2021. The purpose of the NOP was to provide notification that an EIR for the proposed Project was being prepared and to solicit Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 4 guidance on the scope and content of the document. In addition to the recipients prescribed by Section 15082, subdivision (a), the City provided notice to property owners within 500 feet of the Project site. The City received seven written comment letters during the NOP review period and several oral comments during the Scoping Meeting. NOP letters were received from:
• Edward McKervy – inquiring about traffic flow at the intersection of Henderson and Westwood.
• Ben Ennis – expressing concerns regarding Lombardi Street traffic issues, specifically, congestion.
• California Department of Fish and Wildlife – providing recommendations for Swainson’s hawk, tricolored blackbird, burrowing owl, and nesting bird mitigation. • California Department of Toxic Substances Control – providing guidance for hazards and hazardous materials analysis in the draft EIR.
• California Department of Conservation – providing recommendations regarding potential agricultural land conversion analysis, feasible alternatives and feasible mitigation measures.
• California Native American Heritage Commission – providing guidance on consultation with locally affiliated California Native American tribes, in compliance with AB 52 and SB 18.
• California Department of Transportation – providing comments consistent with the State’s smart mobility goals to support a vibrant economy and sustainable community.
Draft EIR
The Draft EIR was properly noticed and circulated for public review and comment for 45 days, from November 6, 2021, through December 21, 2021. The Notice of Availability was published in the Porterville Recorder on November 6, 2021. The Draft EIR and Appendices were uploaded to the State Clearinghouse website for distribution and notices were mailed to local agencies, property owners within 500 feet of the Project site, and other interested individuals. The City received five comment letters on the Draft EIR. These letters are reproduced in their entirety in Chapter Two of this Final EIR and responses are provided after each letter.
These comments and responses that make up the Final EIR, in combination with the Draft EIR, constitute the EIR that will be considered for certification by the of Porterville City Council.
Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 5 CEQA Requirements
Under CEQA, the Lead Agency must prepare and certify a Final EIR prior to a proposed project being approved. The contents of a Final EIR are specified in Guidelines Section 15132, which states that a Final EIR must consist of the following:
a) The Draft EIR or a revision of the Draft EIR.
b) Comments and recommendations received on the Draft EIR either verbatim or in summary.
c) A list of persons, organizations, and public agencies commenting on the Draft EIR. d) The responses of the Lead Agency to significant environmental points raised in the review and consultation process.
e) Any other information added by the Lead Agency.
The Lead Agency must provide each agency that commented on the Draft EIR with a copy of the Lead Agency’s response to such comments a minimum of 10 days before certifying the Final EIR.
Use of the Final EIR
The Final EIR allows the public and the City an opportunity to review revisions to the Draft EIR and the responses to comments received during the Draft EIR public review period. The Final EIR serves as the environmental document to inform the City of the environmental consequences of the proposed project, either in whole or in part, or one of the alternatives to the project discussed in the Draft EIR.
As required by Guidelines Section 15090, subdivisions (a)(1)-(3), a lead agency, in certifying a Final EIR, must make the following three determinations:
1) The Final EIR has been completed in compliance with CEQA. 2) The Final EIR was presented to the decision-making body of the lead agency (i.e., the City Council), and the decision-making body reviewed and considered the information in the Final EIR prior to approving the project.
3) The Final EIR reflects the lead agency’s independent judgment and analysis.
As required by Section 15091 of the CEQA Guidelines, a public agency cannot approve or carry out a project for which an EIR has been certified that identifies one or more significant environmental effects of the project unless the public agency makes one or more written findings (Findings of Fact) for each of those significant effects, accompanied by a brief explanation of the Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 6 rationale to reach findings supported by substantial evidence in the record. The possible findings are as follows:
1) Changes or alterations have been required in or incorporated into the project that avoid or substantially lessen the significant environmental effect as identified in the Final EIR. 2) Such changes or alterations are within the responsibility and jurisdiction of another public agency and not the agency making the finding. Such changes have been adopted by such other agency or can and should be adopted by such other agency. 3) Specific economic, legal, social, technological, or other considerations, including provision of employment opportunities for highly trained workers, make infeasible the mitigation measures or project alternatives identified in the Final EIR.
Additionally, pursuant to Guidelines Section 15093 subdivision (b), when a Lead Agency approves a project that would result in significant unavoidable impacts that are disclosed in the Final EIR, the agency must state in writing the reasons supporting the approval. The Statement of Overriding Considerations must be supported by substantial evidence in the Lead Agency’s administrative record.
For this proposed Project, because it would not result in significant and unavoidable impacts (assuming the City finds all mitigation measures included in the Draft EIR to be feasible), the City is not required to adopt a Statement of Overriding Considerations prior to approving the proposed project (see also Public Resources Code Section 21081).
If as part of certifying the EIR the City requires inclusion of mitigation measures, it will also adopt a Mitigation Monitoring and Reporting Program (see Public Resources Code Section 21081.6).

Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page |47 Written Comment Letters
Comment Letter 1:
Comment 1-A: The traffic study was done while Burton School Lombardi Campus was closed due to Covid restrictions and cannot possible be correct. For instance, 3 times a day, traffic is backed up from the school to Westfield and even around the corner onto Westfield at times and they have it designated as a Level B – short delays – intersection when I have spent 35 minutes in the traffic trying to get to my house.
Response to Comment 1-A: As stated on page 5 of the Traffic Study, provided as Appendix C of the Draft EIR, the AM and PM traffic peak hours were taken in May of 2021. At that time, the Summit Charter Academy, Lombardi Campus was operating with approximately 30% of the students on campus, with the remaining students attending class remotely. Accordingly, an Addendum to the traffic study was prepared, and is included as Appendix A of this Final EIR.
Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 9 Traffic studies base the peak hour of analysis on the peak hour of adjacent street traffic. These peak hours generally coincide with the AM and PM commute hours. As described in the study, 2- hour counts were taken in the AM and PM hours (in 15-minute increments) and the peak hour was determined to be within the 2-hour window. The school AM peak hour corresponds with the peak hour of adjacent street traffic and is therefore reflected in the analysis. The PM peak hour for schools is typically earlier than the PM peak hour of adjacent street traffic, which is the case for the Summit Charter Academy. Therefore, the PM peak hour analysis was not adjusted.
An investigation was made to better represent the existing (pre-pandemic) traffic volumes on Lombardi Street in the AM peak hour. Although the campus is now operational with most students on campus, there still may be remote attendees. Therefore, a trip generation calculation based on the Institute of Transportation Engineers Trip Generation Manual was made for the school using a 600-student population. The trip generation was added to the existing counts taken in May of 2021 with a reduction to account for the student population that was attending inperson at the time. It is also assumed that once the project is built out, there will be students that will attend Summit Charter Academy. The adjusted 2021 traffic is shown on the attached revised Figure 4 of Appendix A. Figures 5 through 8 of Appendix A show the adjusted volumes with and without project traffic in the existing and future conditions.
Level of service (LOS) analysis was performed using the revised volumes. The LOS analysis indicates a LOS F for the existing condition. With the project added the delay increases by 13.3 seconds in the existing condition. The future scenario with anticipated background growth indicates that the delay is outside of the range of the analysis and is at an unstable condition and therefore the project traffic impact on the intersection is not definable.

A project cannot be made to mitigate, offset, or otherwise correct an existing condition; it can only be made to address its own impacts. The mitigation and recommendations contained in the Traffic Study reflect appropriate mitigation for the intersection of Lombardi Street and Westfield Avenue and other affected intersections and segments and are still valid for the adjusted analysis.
Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 10 Comment 1-B: Neil Ward’s house is such that it does not allow 2 lanes of traffic going south. And yet the Circulation Element shows Lombardi Street as being a future collector from an extension of Castle coming through our property and then back south on Lombardi. The collector street should come through our property and through the proposed annexation and connect to Westwood at the Nancy Lane intersection with a street other than Lombardi going to the school.
Response 1-B: This comment appears to propose that the Project should be responsible for construction of a new collector street not currently identified within the General Plan Circulation Element and concomitantly should not construct N. Lombardi Street, itself a collector street identified in the General Plan Circulation Element. Short of processing an amendment to the General Plan Circulation Element to add and remove (respectively) the two collector streets as suggested, the City cannot simply require a project to 1) ignore policy-driven improvements to an existing major street right-of-way and 2) dedicate and improve another. Such an amendment is neither proposed as part of the Project nor identified as an option or requirement within the traffic analysis prepared for the Project. Additionally, the comment incorrectly asserts that there is insufficient distance between the existing N. Lombardi Street right-of-way and the existing dwelling on APN 245-010-037 to accommodate dedication of right-of-way for, and construction of, southbound street improvements. Those dedications and improvements are a required part of the Project contained within the conditions of approval for the tentative map. Following dedication, the western right-of-way of N. Lombardi Street would be approximately 50 feet from the existing home, and approximately 35 feet from the existing septic tank in front of the home.
Construction of street improvements may require relocation of an existing wood fence.
Comment 1-C: Also, I have some concerns about this annexation creating county islands with the 2 residences being left out of the annexation.
Response to Comment 1-C: This comment incorrectly asserts that two residential parcels within the overall Project area (to wit: APNs 245-010-037 and -041) would not be included in the proposed annexation. To the contrary, those parcels will be annexed into the City as described on Pages 1-2 and 2-5 of the Draft EIR and illustrated in Figure 2 – Site Aerial on page 2-4 of the Draft EIR.

CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 15 Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 16 Comment 2-A: Having paid for numerous Environmental Impact Reports and Traffic Studies in my career as a developer, I am rather shocked at the deficiencies in the one for the Lombardi Project and how it would affect the surrounding neighborhoods with traffic, especially on Westfield and Lombardi Streets. I might also make known that I live on Lombardi Street so I am very aware of the traffic issues that now exist and will be much greater if this project should be approved as now proposed.
Response to Comment 2-A: Comment noted, no response necessary.
Comment 2-B: An EIR is explained as being the process of evaluation the likely environmental impacts of a proposed project or development, taking into account inter-related socio-economic, cultural and human-health impact, both beneficial and adverse.
Very little of the benefits of the project, other than helping the city meet their housing quota, and none of the adverse were addressed in this EIR, as well as any steps of mitigation other that TRA-1 and TRA-2. The social aspects are painfully missing completely.
Response to Comment 2-B: The comment purports to explain the purpose of an EIR; however, the statement within the comment appears to be copied and pasted from one of several websites that provide general information about the environmental review process (specifically, the “Environmental Impact Assessment”) used in the Republic of India, the People’s Republic of Bangladesh, and other foreign states or from the website of the Convention on Biological Diversity (to which the United States is not a party and which would be irrelevant in the context of CEQA, regardless). As is relevant to the California Environmental Quality Act, California Public Resources Code Section 21002.1, subdivision (a) states: “The purpose of an environmental impact report is to identify the significant effects on the environment of a project, to identify alternatives to the project, and to indicate the manner in which those significant effects can be mitigated or avoided.” The EIR does identify the potential for significant effects to air quality, biological resources, cultural resources, and transportation/traffic and includes appropriate, Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 17 feasible mitigation measures that will reduce those effects to a less than significant level. Further, while the comment asserts that “social aspects are painfully missing,” it fails to illustrate any example of such missing aspects. In any event, Guidelines Section 15131 subdivision (a) states, “Economic or social effects of a project shall not be treated as significant effects on the environment.” While an EIR may consider economic or social effects of a project as they may relate to physical changes, no such effects are identified in the EIR or by the commenter.
Importantly, PRC Section 21082.2, subdivision (c) notes, “Argument, speculation, unsubstantiated opinion or narrative, evidence which is clearly inaccurate or erroneous, or evidence of social or economic impacts which do not contribute to, or are not caused by, physical impacts on the environment, is not substantial evidence.” That clause of the statute is further elaborated upon in Guidelines Section 15064, subdivisions (f)(4)-(f)(6). As presented in the Initial Study and associated EIR, all potential impacts resulting from the Lombardi Development Project are either less than significant or less than significant with mitigation incorporated. Mitigation measures are presented in the Air Quality, Biological Resources, Cultural Resources, and Traffic and Transportation sections of the EIR. The alternatives analysis is contained in Chapter 4 of the EIR.
Comment 2-C: Since my concern is the traffic issues, I will concentrate on the traffic study.
Basically, there was no traffic study. Just figures compiled from existing data. To address the traffic issues, one would have to do a study during the time that Burton School Lombardi Campus was in session (The traffic study consists of an existing peak hour turning movement counts that was taken in May of 2021, when Burton School was not in session) and when traffic is backed up on Lombardi Street up to 3 times a day when students were being dropped off or picked up, this being a Charter School where students are driven from other points in the County by automobile, which is the main source of transportation to the school. It is impossible for the intersection at Lombardi and Westfield to have a Level of Service rating a “B” as per the traffic study. This traffic to the school is as much or more that the proposed project and yet was not even taken into consideration. I would suggest that the traffic on Lombardi by itself would exceed the estimated figures for the Lombardi-Westfield intersection. Of the students that attend the Lombardi campus, I realize a small number walk and some are transported by the 3 busloads (total of 65 kids according to staff), so if 50 kids walked or rode bikes (they don't at that age, kindergarten through 5th grade, and I have counted them numerous days) that means that 490 kids are brought to school by automobile. Other than one side street, they all have to come down Westfield to Lombardi. Consequently, there is a daily traffic jam.
Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 18 Response to Comment 2-C: This comment asserts inadequacy of the traffic analysis prepared for the Project, although it provides no evidence to substantiate that claim.
Additionally, under the provisions of Senate Bill 743 (2013), CEQA and (ultimately) the CEQA Guidelines were amended to reflect a paradigm change in how California public agencies are required to analyze transportation impacts for projects. Historically, level of service (LOS), which assesses transportation impacts as measured by traffic congestion and delay, had been used as the primary threshold for determining project traffic impacts. In response to concerns about air quality and greenhouse gas emissions from vehicles, the State determined that vehicle miles traveled (VMT) was a more suitable method than LOS for assessing project effects. Accordingly, since July 1, 2020, lead agencies have been required to utilize VMT as the primary consideration in their analyses and project review; CEQA is essentially no longer concerned with congestion and traffic delay.
However, because the General Plan still uses LOS as a method for determining infrastructure needs and the City must examine whether a project would “conflict with a program, plan, ordinance, or policy addressing the circulation system,” LOS analysis is still completed. As noted in the traffic study and its addendum and with implementation of Mitigation Measure TRA-1, no such policy would be violated. Also, see Response to Comment 1-A.
Comment 2-D: As a point of reference, show me where the traffic study even considered the traffic generated by the school with the 605 current enrollment of students, with being delivered to the school each day traveling on Westfield and Lombardi Streets when in session and also for all of the extra-curricular activities when cars are parked up to ½ mile away.
Response to Comment 2-D: Please see Response to Comment 1-A and Response to Comment 2- C. Also, note that the Project cannot be made to mitigate or alleviate existing circumstances.
Comment 2-E: The traffic report part of the study on page 127 says “As such, cumulative impacts are also considered less than significant with mitigation incorporation”. That is with the incorporation of TRA-1 mitigation and TRA-2 mitigation. Are you kidding me? TRA-1 is the standard fees for capital improvements to the infrastructure based on a level of Service in 2041 to existing intersections and there is no assurance that any of it will end up addressing traffic issues with this project, Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 19 or if it should, when. TRA-2 is for the improvement of the bus stop that is very seldom used and if it was, it would have no bearing on traffic issues on the adjacent streets.
Response to Comment 2-E: This comment misrepresents the provisions of Mitigation Measure TRA-1 and demonstrates an apparent misunderstanding of Mitigation Measure TRA-2. The location-specific fair-share costs identified in TRA-1 are required irrespective of any fees that the Project may be responsible for under the City’s Development Impact Fee program. Projects for which a traffic study are not prepared would generally simply be responsible for payment of such fees. Since a traffic study was prepared for this Project and that study identified impacts to specific components of the City’s infrastructure, fair-share costs for improving those components were assigned. If those fair-share costs are less than the impact fees that would otherwise be due, the project will be responsible for both the specified costs and the difference between those costs and its fee responsibility. If the fair-share costs exceed the impact fees, the project is responsible for paying the higher amount. The City is precluded both from making a project mitigate an existing condition (as noted in Response to Comment 2-D) and from requiring a project to fully fund capital improvements that are not strictly necessary for the function of that project. By requiring the Project to pay a fair-share cost towards specified improvements and to meet its impact fee obligation as described above, the Project will have mitigated its specific impacts and will not conflict with a policy related to the circulation system. Consistent with the details contained in Response to Comment 2-C, TRA-2 is not intended to address traffic issues on adjacent streets, because those issues are no longer expressly of concern under CEQA. As noted on Page 3-109 of the Draft EIR, the City adopted the County of Tulare SB 743 Guidelines on September 21, 2021. Included within those Guidelines are the methods for mitigating VMTrelated impacts. Based on the trip-based costs shown in the Guidelines, by funding the identified improvement the Project will have mitigated its potential impacts to VMT.
Comment 2-F: Besides not addressing the traffic issues with Burton School Lombardi Campus, the 2 lane bridge that bottlenecks the traffic on Westwood south of this project is not addressed, The City’s Traffic Circulation Plan incorporated in the General Plan is totally ignored. How can this be? Is it because it calls for a collector street from the extension of Castle to Lombardi south to Westfield and Lombardi Street cannot be widened to 4 lanes because of the existing house that would be in the south bound lanes, so it would be nothing more that a bottleneck and even worse when it comes to Westfield. No planning is better than bad planning.
Response to Comment 2-F: The comment again implies that the Project should be responsible for alleviating existing conditions and, contrary to the substantial evidence provided in the traffic Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 20 study and addendum, asserts significant impacts to certain offsite facilities. It also again incorrectly refers to the proximity of N. Lombardi Street to the existing dwelling on APN 245- 010-037. Please see Response to Comment 1-A, Response to Comment 1-B, Response to Comment 2-C, and Response to Comment 2-D.
Comment 2-G: With regards to the EIR, my concerns and that of the neighborhoods adjacent to this project is that the social component has been completely ignored which is a major component of the environment issues. This impact report basically ignores any impacts of any type to the surrounding neighborhoods which would increase with this project.
Response to Comment 2-G: As described in Section 1.1 of the EIR – Purpose of the EIR (page 1- 1), the document was prepared in accordance with CEQA and the CEQA Guidelines. Also, please see Response to Comment 2-B.
Comment 2-H: The EIR determined that the Reduced Project Alternative would be the environmentally superior alternative, although it would not fully meet the project’s objectives. That seems to be the one point that we all agree on.
Response to Comment 2-H: The Executive Summary mistakenly summarized that the Reduced Project Alternative would be the environmentally superior alternative. The full alternatives analysis is provided in Chapter 4 of the EIR where it describes that the No Project alternative will avoid both the adverse and beneficial effects of the project. Please refer to Chapter Three – Text Changes to the Draft EIR for the textual changes in the Executive Summary.
Comment 2-I: The density and traffic on adjoining streets is such that a lot more work needs to be done in this EIR to protect the public.
Response to Comment 2-I: This project cannot be required to mitigate or correct an existing situation. Please see Response to Comment 2-F.
Comment 2-J: The General Plan identifies the Project site as being within the Low Medium Density Residential, Medium Density Residential, Neighborhood Commercial, and Parks and Recreation designations as well as within a neighborhood center.
Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 21 The zoning map shows the site as prezoned to the RS-1 (Very Low Density Residential) zone with the Residential Neighborhood (RN) Overlay District. The RN Overlay District is intended to implement neighborhood town centers and neighborhood design guidelines by requiring that development conforms to the underlying land uses illustrated on the Land Use Diagram.
Response to Comment 2-J: Comment noted, no response necessary.
Comment 2-K: In some places in the EIR, it states 230 homes and in other places, it states 261 homes. Which is it? In either case, it is a large increase in the number of residences from the ‘Very Low Residential” General Plan designation.
Response to Comment 2-K: The EIR analyzed impacts from the development of 230 homes.
Technical analysis in the Air Quality Study, the Traffic Study, and the Initial Study assessed impacts from the development of 261 homes, which has presented a more intensive environmental impact than the Project itself.
Comment 2-L: An EIR should accomplish the following;
1-Potentially screens out environmentally unsound projects 2-Propose modified designs to reduce environmental impacts 3- Identify feasible alternatives
4- Predict significant adverse impacts
5- Identify mitigation measures to reduce, offset, or eliminate major impacts 6-Engage and inform potentially affected communities and individuals 7-Influence decision making and the development of terms and conditions We believe at this point, the EIR has not addressed numbers 2-3-4-5-at all and the timing has not happened on the balance.
Response to Comment 2-L: Similar to the statement contained in Comment 2-B, the commenter has copied and pasted information from an online source regarding the “Environmental Impact Statement”, which is not related to CEQA, and expresses an opinion that the City has not Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 22 complied with the “requirements.” Insofar as the list included in the comment is not misaligned with the regulatory and procedural aspects of CEQA, the City puts forth, as described in Chapter 2 of the Draft EIR, Response to Comment 1-A, Response to Comment 2-B, Response to Comment 2-C, Response to Comment 2-E, Response to Comment 2-G, Response to Comment 2-P, Response to Comment 2-R, Response to Comment 2-T, Response to Comment 2-U, Response to Comment 2-U, Response to Comment 3-B, Response to Renee Kirtley, and Response to Jenny Cox, that it has adequately addressed the items on the list. Further, as described in Response to Comment 2- N, as the Project would not result in any significant environmental impacts after mitigation, no alternative development scenarios were evaluated.
Comment 2-M: We are of the opinion that the project’s social elements are much more important and complex than addressed in this report. Most of the EIR’s social-related information is limited to purely descriptive input without any serious effort to analyze its significance or determine its relevance for the specific project to which it pertains. As stated in the State CEQA Guidelines, an EIR is an "informational document" intended to inform public agency decision makers and the public of the significant environmental effects of a project, identify possible ways to minimize the significant effects, and describe reasonable alternatives to the project.
Response to Comment 2-M: The commentor again asserts that profound social effects would result from the Project but fails to identify any. Please see the Response to Comment 2-B and Response to Comment 2-N.
Comment 2-N: The EIR only analyzed the proposed project and the no project alternative, although it states that it did a “Reduced Project Alternative” I have not found it in the EIR.
Response to Comment 2-N: Please see the Response to Comment 2-H. As described on Page 4-1 of the EIR, “Based on the rule of reason as set forth in the CEQA Guidelines Section 15126.6, the only alternatives that should be analyzed in the EIR are those that are capable of eliminating or substantially reducing significant adverse environmental impacts. The results of the analysis in this EIR and accompanying IS indicate that the proposed Project would not result in any significant environmental impacts; therefore, no alternative development scenarios are evaluated.”
Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 23 Comment 2-O: They have neglected to give an in depth study as to how the traffic would affect the surrounding neighborhoods and also the school. There is no part of the traffic study that shows how much traffic might be generated on each surrounding street at full build out of the project, only traffic into and out of the subdivision. It only gives enough information from data for future traffic available to anyone. It is basically tailored to meet the proposed project objectives without any consideration given to the environmental impact to the neighboring subdivisions. We believe that the projects impact is not stated and/or is grossly misleading.
Response to Comment 2-O: The comment provides the commenter’s admitted opinion that the traffic study is inadequate. The City of Porterville utilizes the “Caltrans Guide for the Preparation of Traffic Impact Studies” (Guidelines) to analyze potential impacts resulting from development projects. With regard to surrounding local roadways, the Guidelines state that the intersections and streets where project traffic is expected to reach 50 trips be analyzed. The surrounding neighborhoods do not have enough attractors (destinations) for project traffic to reach the 50-trip threshold on surrounding neighborhood local roads. See Response to Comment 1-A.
Comment 2-P: Furthermore, it appears that the baseline for air quality was taken from the monitoring station at the airport instead of actual monitoring closer to the project.
A lot of this study is cut and pasted using available data and prediction models instead of doing a comprehensive study, leading to an insufficient level of analysis of the information gathered by studies, leading to an insufficient level of analysis of the information gathered by studies.
Response to Comment 2-P: The San Joaquin Valley Air Pollution Control District operates one air quality monitoring station in Porterville, at the airport. Accordingly, this station provides the appropriate baseline data for development projects in the Porterville area. Drawing conclusions from available data and prediction models is a comprehensive study.
Comment 2-Q: Allowing a zone change to very small lots from the General Plan designation would be a step backwards taking into consideration the traffic issues as they exist and will only get worse as there is not a plan to lessen the congestion of traffic that already exists on the streets surrounding the project. I know that there is a large group of residents in the neighborhoods surrounding this project that are, like I am, concerned about the traffic issues that now exists and how adding another 230 homes to the mix without solving what already exists would be a major concern, along with solving the access to Burton School Lombardi Campus.
Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 24 Response to Comment 2-Q: The comment, not strictly confined to CEQA, demonstrates a misunderstanding of the distinction between the General Plan Land Use and the zoning of a site as well as how they correlate to the overall intensity of development that could occur on that site.
First, while the proposed RS-2 zoning would accommodate lots with a minimum size of 5,000 square feet, an examination of the map shows that 155 of the proposed lots are 6,000 square feet or greater, including 78 lots of at least 7,000 square feet. Thus, while the Project does include smaller lots than other neighborhoods in the vicinity, the overall development is not at a noticeably higher density than the surrounding area and is accommodated by the Low Density Residential land use, consistent with the surrounding area. Second, although the City acknowledges that it cannot use planned land use as a baseline for determining impacts under CEQA (see Woodward Park Homeowners Assn., Inc. v. City of Fresno (2007) 150 Cal.App.4th 683) and has not done so in this EIR, we shall note for the sake of discussion that under the current planned land use and corresponding zoning, the Project site could accommodate up to 336 dwellings (including smaller lots than proposed within the Medium Density Residential area and/or attached multifamily dwellings), along with 41,000 square feet of commercial development, much of which would not be subject to discretionary review (or, therefore, CEQA). Additionally, if residential development were proposed at the intensity identified in the General Plan, the City would be prohibited from requiring a reduction in the number of proposed dwellings under the provisions of the Housing Crisis Act of 2019 (Government Code Section 66300, et seq.).
Accordingly, while the City properly examined Project impacts by comparing the Project as proposed to the existing baseline (agriculture) as opposed to the development potential under the planned land uses, for illustrative purposes it is evident that the planned land uses could support a substantially more intense development than the Project is actually proposing, and that the City would likely have less discretionary oversight in that circumstance. Also, please see Response to Comment 1-A, Response to Comment, 2-C, Response to Comment 2-D, and Response to Comment 2-F.
Comment 2-R: We all depend on the City to adopt policies and procedures that safeguards the rights to neighborhoods that we can access our homes reasonably well on city streets without traffic gridlock which then becomes to a quality of life issue, and there is no doubt that those folks that have invested most of their savings into a home for their family do not want to see their families lifestyle degraded due to a flawed EIR. These are issues that the citizens have a right to and should not have to be brought to the City's attention. They voted on you to protect them and the future design of this city. Any consideration of the EIR and it's accompanying traffic study should be sent back for corrections and rejected in it's present form.
Response to Comment 2-R: Please see the Response to Comment 1-A.
Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 25 Comment 2-S: It should incorporate the alternatives to the proposed project which are considered the “heart” of an EIR.
Response to Comment 2-S: While in County of Inyo v. Yorti (1973) 32 Cal.App.3d 795 the 3rd District Court of Appeal noted that “in many respects the EIR is the heart of CEQA”, the City is not aware of any source describing alternatives analysis as “the ‘heart’ of an EIR.” Also, please see the Response to Comment 2-N.
Comment 2-T: Appropriate mitigating measures should be incorporated.
Response to Comment 2-T: Please see the Response to Comment 2-B.
Comment 2-U: Insufficient or outdated prediction models are not being used.
Response to Comment 2-U: Modeling conducted by both the Air Quality and Traffic Study experts were both appropriate and industry-standard.
Comment 2-V: Most of all, it should have included correct traffic studies and the current effect on the surrounding neighborhoods and way to minimize the effects and a description of reasonable alternatives. Unfortunately, this study is more to meet the project objectives instead of addressing the significant impacts, especially the traffic issues.
Response to Comment 2-V: Please see all Responses to Comment 2.
Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 26 Comment Letter 3:
Comment 3-A: As you are aware, the proposed Lombardi Development Project creates several interesting situations for me personally. A year ago, I purchased a house that will be directly impacted by the new project and yet understand the new homes will be located within the Burton School District boundaries, which does provide a potential increase in their student population that would impact my current employer, Porterville Unified School District. However, I am aware of several new housing projects that will add inventory to the PUSD boundaries and as long as it is an equitable distribution within the city of Porterville, I hold no objections to the Lombardi project.
Response to Comment 3-A: Comment noted. No response necessary, the City appreciates your time.
Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 27 Comment 3-B: I do have a few concerns around the road infrastructure for the project. I do believe the current area with the Nancy Ave. entrance where a west entrance four lots north will not be an issue as there is enough space for traffic to pass for those heading southbound and turning east for that new entrance, but I could see some potential issues with northbound traffic if there are no plans to expand the street.
While I do not live in that area, I'm sure there are some concerns on Lombardi Street unless of course a new west-east street is being built north of Westfield that would alleviate some of the traffic. With a right-hand turn available at Westfield for northbound traffic on Westwood, I would hope the same right-hand lane would be available for westbound traffic on Westfield for those reaching Westwood.
Response to Comment 3-B: It should be noted that access to the development would be via Westwood Street, Westfield Avenue, and Lombardi Street, so future residents of the Project would be able to avoid Lombardi Street during school pickup/dropoff times.
Comment 3-C: Despite those concerns, as a resident of Porterville for over six years, I feel change is always important even if some in the community disagree. As the former board chairman for the Porterville Chamber of Commerce and current commissioner on the Porterville Parks and Leisure Commission, I fully understand the need for more housing in the area. I appreciate the thoughtfulness of the developer to provide a new park for the project. With the relocation of Eagle Mountain Casino, we need to create more housing to add more businesses in the area, which will create more job opportunities for residents. One positive thing and perhaps one that a lot of people did not realize through the COVID-19 pandemic is that Porterville will be able to provide a low-cost community for those who are now able to work from home. Housing will be available for low-to-middle class residents who might not otherwise be able to afford housing in the urban areas of the state. In closing, I think this project will be a benefit for Porterville and the surrounding community.
This email serves as notice that I am writing this public comment on my own and has not been endorsed by any member of the PUSD Governing Board or my direct supervisor. I am solely writing this public comment as a proud resident of Porterville. Thank you.
Response to Comment 3-C: Comment noted. No response necessary, the City appreciates your time.
Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 28 Comment Letter 4:
Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 29 Comment 4-A: The city continues to expand facing challenges of balancing the growth, with incentives for developers which always raises some ethical dilemmas for our city leaders. Our city continues to collect below average park fees from developers which hurt growth and maintenance in other areas as we expand. Other cities collect more money from developers so that trade-offs make for more responsible growth like collecting a half million dollars in developer fees to fund the lighting at our sports complex for example.
Response to Comment 4-A: The comment refers to “incentives for developers” and “ethical dilemmas” and states that that the City collects "below average” development impact fees (without indicating what the average might be). The City is unaware of any incentives that the developer may have received that may lead to any ethical dilemmas, as the development is required to comply with all City standards, regulations, policies, etc. and is responsible for funding and/or installation of onand offsite improvements (including a 2.99-acre improved park within the project) and payment of development fees as would be any other similar project—the Project will also dedicate a wellsite.
Development impact fees are based on a nexus study prepared pursuant to the Mitigation Fee Act Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 30 (Gov. Code Section 66000, et seq.). Unless a project-specific study is prepared that illustrates the project would have a greater effect on certain facilities—such as the fair-share for street improvements based on the traffic study—a project can only be made to pay the fees that are in place when it's deemed accepted for processing, and those fees have to be based on the adopted fee schedule. What the City of Porterville charges for its fees is unrelated to what any other public agency charges, as each agency has prepared its own study based upon various factors such as development potential within the urban development boundary and (in the case of parks) the desired ratio of parks per population identified in the General Plan and/or the presence or absence of a Quimby Act ordinance (specific to parkland dedication), and the willingness of residents to fund maintenance activities. Importantly, it should be noted that “park fees from developers” cannot be used for maintenance. Non-standard incentives, fees, improvement requirements, and related components (such as installation of lighting at a non-project-related facility) can be included in a project as part of a development agreement (Gov.
Code Section 65864, et seq.); however, a development agreement must be requested by the developer and no such agreement is part of this project.
Comment 4-B: After all who wants to tell the folks on Westfield Avenue they can expect a 4 lane road in front of their house in the near future so we can fast track a housing development in the area?
Response to Comment 4-B: The comment erroneously states that the Project would expand W.
Westfield Avenue to four lanes. Not only is such an expansion not a part of the Project, but it should also be noted that the General Plan Circulation Element does not identify W. Westfield Avenue as having more than two through lanes at any location in the City.
Comment 4-C: Summit Charter is on the north end of Lombardi which is a dead end road where all traffic needs to go north to school and then back south every morning and every evening, to deliver and pick up 600+ students, from other parts of town outside this neighborhood. All that traffic adds to the bottlenecks on Westfield East & West. This also contributes to the 2 lane bridge bottleneck just north of CVS on Westwood where the expansion to 4 lanes with new bridge remains incomplete while it has direct connections to Westfield and the Brookside Subdivision that will exacerbate the bottleneck if not completed soon. This section around the bridge is very dangerous at peak times backing up traffic through the light and left turns hold traffic on the bridge. These 2 lane residential roads were not meant for this Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 31 much traffic so something has to give. The city is considering 4 lanes for Westfield and several traffic lights in the area as a solution, but I don't think the residents in this area are aware that they only have a month or two to weigh in on the project.
Moreover the current proposed traffic solutions don't address the REAL bottlenecks in the area. The proposed solutions may make things worse.
Response to Comment 4-C: Please see Response to Comment 2-F and Response to Comment 4- B.
Comment 4-D: An alternative route not in the plan is to extend Castle street West to Lombardi to solve the dead end issue and move traffic in/out of the area Eastward to Newcomb reducing the traffic on Westfield and improving the emergency service access to this new housing project and to the school. Castle street expansion west to the School will also open up north/south traffic on Matthew where the new traffic light will be to get traffic to Henderson to the south and traffic to the north via the proposed Castle extension without adding traffic to Westfield. The Castle street extension would help the traffic flows significantly in the entire area and would diminish the need to make Westfield 4 lanes for the foreseeable future. The Castle alternative may be desirable for the Westfield street residents that would be made to trade their front yards for a 4 lane thoroughfare and the additional city expense for eminent domain to make Westfield 4 lanes. This will also mitigate traffic bottlenecks on North/South Newcomb which is already 4 lanes and designed for more traffic.
Response to Comment 4-D: See Response to Comment 1-B, Response to Comment 2-D, and Response to Comment 3-B.
Comment 4-E: Additional things to consider for the project to ensure responsible growth. The lot sizes proposed are smaller than all of the lot sizes in the surrounding neighborhoods. Smaller lots mean more residents, more traffic, more pollution & more water. Larger lots consistent with surrounding neighborhood will protect the integrity and consistency of past projects and help maintain the values of the homes in the previous developments. Larger Lots will reduce the traffic demand with fewer residents. Larger lots will reduce the pollution that is a significant Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 32 concern in the environmental study. Larger Lots will translate into fewer connections to the water system. IF we allow smaller lots the developer makes more money and we have to suffer with more traffic, more pollution, more water hookup’s and a neighborhood with smaller houses in the middle of a neighborhood with larger houses. In Toto the integrity and consumption in the area demands we remain consistent with past development in this area of town adjacent to the canal in northwest Porterville.

CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 37 Comment 5-A: Project Related Emissions
At the federal level under the National Ambient Air Quality Standards (NAAQS), the District is designated as extreme nonattainment for the 8-hour ozone standards and serious nonattainment for the particulate matter less than 2.5 microns in size Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 38 (PM2.5) standards. At the state level under California Ambient Air Quality Standards (CAAQS), the District is designated as nonattainment for the 8-hour ozone, PM10, and PM2.5 standards.
Based on information provided to the District, Project specific annual emissions from construction and operation emissions of criteria pollutants are not expected to exceed any of the following District significance thresholds: 100 tons per year of carbon monoxide (CO), 10 tons per year of oxides of nitrogen (NOx), 10 tons per year of reactive organic gases (ROG), 27 tons per year of oxides of sulfur (SOx), 15 tons per year of particulate matter of 10 microns or less in size (PM10), or 15 tons per year of particulate matter of 2.5 microns or less in size (PM2.5).
Response to Comment 5-A: The City appreciates the District’s concurrence with the EIR conclusion that Project specific annual emissions will not exceed significance thresholds.
Comment 5-B: Health Risk Screening/Assessment
The District has reviewed the Project’s Health Risk Assessment (HRA) and has the following comments:
o Per Appendix B (Air Quality, Greenhouse Gas, and Energy Impact Assessment), diesel exhaust PM2.5 was used to estimate construction-related diesel particulate matter (DPM) emissions in the HRA. As such, the pollutant type, “PM2.5”, was used in AERMOD for the HRA. However, the District recommends the HRA be revised to ensure annual PM10 diesel exhaust emissions and the pollutant type, “PM10”, in AERMOD are used to
estimate the Project’s construction-related emissions and ground level concentrations of nearby sensitive receptors.
o Non-default daily breathing rates were used to calculate the daily inhalation dose associated with the Project. Please include a discussion in the DEIR justifying the use of non-default daily breathing rates for the cancer health risk calculation.
Response to Comment 5-B: The District recommended that the Health Risk Assessment (HRA) for the project be revised to use PM10 exhaust as a proxy for diesel particulate matter (DPM) instead of the PM2.5 exhaust that was used.
Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 39 PM2.5 exhaust emissions were chosen to serve as a proxy for DPM emissions because according to the California Air Resources Board (CARB), 90 percent of DPM is less than 1µm (about 1/70th the diameter of a human hair), and thus is a subset of particulate matter less than 2.5 microns in diameter (PM2.5). See: https://ww2.arb.ca.gov/resources/overview-diesel-exhaust-and-health.
Therefore, the use of PM2.5 as a proxy for DPM is supported through substantial evidence and is consistent with standard professional practice.
Using PM10 as the proxy would overestimate risks associated with construction equipment. The difference in PM10 emissions and PM2.5 emissions is 16.8 pounds for the duration of construction, which is approximately a 7 percent increase. Increasing the reported cancer risk by 7 percent would still result in a mitigated cancer risk of less than 20 in a million at 3.88 in a million for the maximally exposed sensitive receptor (infant). The impact would remain less than significant.
Comment 5-C: Health Risk Screening/Assessment
The District has reviewed the Project’s Health Risk Assessment (HRA) and has the following comments:
o Non-default daily breathing rates were used to calculate the daily inhalation dose associated with the Project. Please include a discussion in the DEIR justifying the use of non-default daily breathing rates for the cancer health risk calculation.
Response to Comment 5-C: The District noted that non-default breathing rates were used to calculate the daily inhalation dose associated with the Project and requested that the DEIR include a discussion justifying using a non-default daily breathing rate for cancer risk calculation.
As shown in Appendix B of the Air Quality Study, the HRA used the 95 percent breathing rate for infant (1090), 80 percent breathing rate for the child (572), and 80 percent breathing rate for the adult. There was a typographical error made in the unmitigated calculations, whereby the HRA used the 30-year breathing rate for the adult of 261 but had used the 70-year breathing rate of 233 for the mitigated adult.

Then updating the adult breathing rate to more conservative 30-year one would increase the mitigated adult risk during construction to 0.09 in one million. It should be noted that the significance determination was based on the infant risk which used the 95 percent breathing rate, as such this clarification does not alter the prior impact determination of less than significant with mitigation. Please see Chapter 3 – Text Changes to the DEIR for the textual revisions.
Comment 5-D: Solar Deployment
It is the policy of the State of California that renewable energy resources and zerocarbon resources supply 100% of retail sales of electricity to California end-use Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 41 customers by December 31, 2045. While various emission control techniques and programs exist to reduce air quality emissions from mobile and stationary sources, the production of solar energy is contributing to improving air quality and public health. The District suggests that the City consider the feasibility of incorporating solar power systems, as an emission reduction strategy for the Project.
Response to Comment 5-D: The developer will be installing solar panels on the residential units consistent with the current California Building Code.
Comment 5-E: Clean Lawn and Garden Equipment in the Community Since the Project consists of residential development, gas-powered residential lawn and garden equipment have the potential to result in an increase of NOx and PM2.5 emissions. Utilizing electric lawn care equipment can provide residents with immediate economic, environmental, and health benefits. The District recommends the Project proponent consider the District’s Clean Green Yard Machines (CGYM) program which provides incentive funding for replacement of existing gas powered lawn and garden equipment. More information on the District CGYM program and funding can be found at:
http://www.valleyair.org/grants/cgym.htm
and http://valleyair.org/grants/cgym-commercial.htm.
Response to Comment 5-E: The City appreciates the information and will pass on the information to the Project developer.
Comment 5-F: Charge Up! Electric Vehicle Charger
To support further installation of electric vehicle charging equipment and development of such infrastructure, the District offers incentives to public agencies, businesses, and property owners of multi-unit dwellings to install electric charging infrastructure (Level 2 and 3 chargers). The purpose of this incentive program is to promote clean air alternative-fuel technologies and the use of low or zero-emission vehicles. The District suggests that the City and Project Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 42 proponent consider the feasibility of installing electric vehicle chargers for the Project.
Please visit www.valleyair.org/grants/chargeup.htm for more information.
Response to Comment 5-F: The Project includes the development of single-family housing and therefore does not qualify for the incentive program.
Comment 5-G: District Rules and Regulation
The District issues permits for many types of air pollution sources and regulates some activities not requiring permits. A project subject to District rules and regulation would reduce its impacts on air quality through compliance with regulatory requirements. In general, a regulation is a collection of rules, each of which deals with a specific topic. For example, Regulation II - Permits encompasses multiple rules associated with the permitting of emission sources such as Rule 2010 (Permits Required), Rule 2201 (New and Modified Stationary Source Review), and others.
Response to Comment 5-G: The City recognizes that the Project is subject to District Rule 9510, District Regulation VIII, and potentially Rule 4102, Rule 4601, and Rule 4641.

Comment 5-I: District Comment Letter
Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 43 The District recommends that a copy of the District’s comments be provided to the Project proponent.
Response to Comment 5-I: The City will provide the applicant with a copy of the comment letter.
Oral Comments
Renee Kirtley
Response to Renee Kirtley: The City appreciates the comment. There is no proposal, currently or in the future, to expand W. Westfield Avenue to four lanes (see Response to Comment 4-B); additionally, any improvements to major street rights-of-way associated with development are paid for by the development, not by the City. It should be further noted that the Project would be developed in multiple phases over multiple years; it will not result in an immediate population increase. As it relates to the EIR, the City has exceeded the notification requirements prescribed by State law by providing the notice of preparation and the notice of availability of the EIR to property owners within 500 feet of the Project site, which notification is not required under CEQA. Notice of public hearing for the discretionary project components is accomplished in compliance with Government Code Sections 65090 and 65091, as applicable, along with Porterville Municipal Code Section 609.06. Impacts to public services, such as fire, police, utilities and water are analyzed in the Initial Study prepared for the EIR. Less than significant impacts resulting from Project development are anticipated. Donating land to the Burton School District is not within the scope of the Lombardi Development Project and in any case not is not feasible for the City to accomplish.

Response to Brock Neeley: The commenter appears to be referring to a parking situation at a location approximately one mile to the east of the proposed Project. This comment does not appear to relate to the Lombardi Development Project. Comment noted.

CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 45 Response to Jenny Cox: The City appreciates your comment. Potential impacts to water supply as a result of Project development were analyzed on Page 70 of the Initial Study to the EIR. The Initial Study concluded that since the site is currently and has historically been in agricultural production with plums, the residential development will utilize approximately 24.15 acre/feet per year less of water than if the site were to continue in agricultural production.

Lombardi Development Project | Final EIR
CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page | 46 Response to David Cox: The City appreciates the comment, which largely attempts to illustrate how growth projections should or should not be used when the City Council considers development proposals. Please note that pursuant to Government Code Section 66300, subdivision (b)(1)(D), the City is prohibited from “establishing or implementing any provision that i) limits the number of land use approvals or permits necessary for the approval and construction of housing; ii) acts as a cap on the number of housing units that can be approved or constructed; or iii) limits the population of the…city.” Consistent with these provisions, the City cannot consider either historical growth rates or future growth projections when considering whether to approve housing development projects, although these rates may still be used for assessing the need for public facilities, infrastructure, etc. The comment also appears to assert that the City should disregard State mandates regarding housing production because those mandates were not developed in consideration of communities like Porterville. This comment is not strictly related to CEQA, although it does touch on the issue of water availability. In that regard, please refer to Response to Jenny Cox.

CITY OF PORTERVILLE | Crawford & Bowen Planning, Inc. Page |47 CHAPTER THREE – Text Changes to the Draft EIR
Revisions and clarifications to the Draft EIR made in response to comments and information received on the Draft EIR are indicated by strikethrough text (e.g., strikethrough), indicating deletions, and underline text (e.g., underline), indicating additions.
These updates and revisions do not constitute significant new information requiring recirculation of the Draft EIR because they do not disclose that a new significant environmental impact would result from the Project or from a new mitigation measure proposed to be implemented; that a substantial increase in the severity of an environmental impact would result unless mitigation measures are adopted that reduce the impact to a level of insignificance; that a feasible project alternative or mitigation measure considerably different from others previously analyzed would clearly lessen the significant environmental impacts of the project, but the Project proponent decline to adopt it; or that the Draft EIR was so fundamentally and basically inadequate and conclusory in nature that meaningful public review and comment were precluded (Guidelines Section 15088.5, subdivision (a)). Instead, the information merely clarifies or amplifies the information in the Draft EIR and does not result in any change in impact conclusion.
