Plan Page 2
Alternative Action
The City Council (Council) could choose not to approve the resolution amending the Urban
Water Management Plan; by doing this, the City of Redding (City) would be out of compliance
with state requirements and ineligible for loans or grant funding until the plan was brought into
compliance.
Background/Analysis
To further water conservation in the State of California, Assembly Bill (AB) 797, the Urban
Water Management Planning Act, was approved in September 1983, and has been amended
numerous times in subsequent years. AB 797 initiated a statewide effort to conserve water by
requiring urban water suppliers that either provide municipal water to more than 3,000 customers
or supply its customers with more than 3,000 acre-feet of municipal water annually, to prepare,
in accordance with the prescribed requirements, an Urban Water Management Plan. The City
developed its Plan in 1985, and has amended the plan every five years as required by law. The
2025 Urban Water Management Plan includes information through calendar year 2025 and is
due in 2026. The City's plan supports long-term resource planning by assessing the reliability of
water sources over a 20-year planning horizon considering normal, dry, and multiple dry years
and by analyzing water demand.
The Water Utility has complied with the provisions of Section 6, Part 2.6, of the California
Water Code by preparing and updating its Urban Water Management Plan. A draft plan was
available on the Water Utility's website and notification was sent to numerous agencies, districts,
private entities, and public entities in accordance with requirements mandated by the Department
of Water Resources. The amended plan addresses conservation requirements and will enable the
City to remain eligible for state grants and loans.
Staff has developed the plan in accordance with state requirements and guidelines and hereby
submits this plan for the Council's consideration.
Envir�onmental Review
Staff has determined that this activity is exempt from environmental review under the California
Environmental Quality Act Guidelines, pursuant to Section 15061(b)(3) — Common Sense
Exemption. CEQA applies only to actions that have the potential to have a significant effect on
the environment. The updated plan includes strategies and potential future efficiency actions;
however, these actions would require separate review under CEQA. This activity would not
result in physical alteration of the environment and it can be seen with certainty that the action
has no potential to have an adverse effect on the environment.

The City of Redding's (City) water service area is located at the northern end of the California's
Central Valley and is along the Interstate 5 (I-5) corridor, south of the City of Shasta Lake and
north of the City of Anderson. The City collectively provides water, sewer, storm drain, waste
management, and electric services to the residents of the City. While most residences are served
by the City's water service, there are neighboring water districts that have overlapping service
areas. The City also serves some parcels that are outside of the City limits.
The City supplies the municipal water system from three primary sources: Surface water drawn
from the Sacramento River one-quarter mile upstream of the Diestelhorst Bridge and treated at the
Foothill Water Treatment Plant (FWTP) just south of Eureka Way; Surface water drawn from
Whiskeytown Lake through the Spring Creek Conduit to the Buckeye WTP (BWTP) in Old
Shasta; and Groundwater pumped from the Redding Area Groundwater Basin by seventeen wells
which are located primarily in the Enterprise pressure zone. Collectively, the City of Redding
water system is capable of treating and distributing a maximum of approximately 55 million
gallons per day(MGD).
At the end of 2025, the service population was estimated to be approximately 90,254. The
population is anticipated to increase to 103,792 by end of year 2050, which is based on an average
annual growth rate of approximately 0.6 percent.
Water demands served by the City are primarily residential, including single-family residential
(SFR)and multi-family residential(MFR),commercial,industrial,and institutional,and landscape
irrigation. A11 connections in the City are metered. The total volume supplied in 2025 was
approximately 7,411 million gallons (MG). The per capita water demand was 222 gallons per
capital per day(GPCD) in 2025.
Supply availability was reviewed under a single-dry year and five-consecutive-year drought. In
addition, a drought risk assessment (DRA) from 2026 through 2030 found that there is sufficient
supply to meet projected demands within the next�ve years.
The City's Water Shortage Contingency Plan (WSCP) was also updated and re-adopted to extend
watering hours during drought stages to accommodate reasonable watering times for the average
customer that may not have an automatic sprinkler timer. The previous WSCP hours discouraged
watering from 7:00 AM to 9:00 PM during Stage 1 Voluntary Conservation. It prohibited watering
from '7:00 AM to 9:00 P1VI during Stages 2 through 6. The newly updated schedule discourages
watering from 9:00 AM to 6:00 PM during Stage 1 Voluntary Conservation. It prohibits watering
during the hours of 9:00 AM to 6:00 PM during Stages 2 through 6, therefore, allowing customers
to water their outdoor landscapes during daylight hours. There were no new requirements set forth
by the California Department of Water Resources (DWR) for drought planning required in the
2025 WSCP or UWMP.

The California Water Code (CWC) requires urban water suppliers within the state to prepare and
adopt an Urban Water Management Plan (UWMP) for submission to 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 AF of water annually, to prepare a UWMP.
The purpose of the UWMP is to maintain efficient use of urban water supplies,continue to 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 2025 Urban
Water Management Plan G�uidebook for Urban Water Suppliers (January 2026) established by the
DWR, constitutes the City's 2025 UWMP.
This 2025 UWMP was prepared in compliance with the UWMPA (CWC §10610 et seq.) and the
Water Conservation Bill of 2009 (Senate Bill [SB] X7-7) and SB 1157. Updated contact
information for the City 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 focus for the City is to provide high quality water,
maximize the efficient use of water, and promote conservation.
1,2e 1 Pr�vic��� �T�mt���x �Tat�z ���xc����a���t �'���s
The City previously prepared UWMPs in 201 S and 2020, which were approved and
adopted on June 26,2016 and November 16,2021. Following adoptions,the UWMPs were
submitted to and formally approved by DWR The 2025 UWMP report serves as an update
to the 2020 UWMP and pulls extensively from that report.

The CWC sections applicable to the UWMPs are summarized in the sections below
�.3,1 �TzTl���a �J�t�r ��r�����T����� P1����i��� Ad��
In 1983, State Assembly Bill (AB) �9� 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 UWIVIPA 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.

a"���� ���1����.�I'� ��'��t°��°:���°� 1���,:��,="�t��;l�����.I�`��° ���,r�C�� I CITY OF REDDING
Other amendments require that UWMPs include provisions for recycled water use,demand
management measures (DMMs), and a WSCP. The UWMPA requires a WSCP which
meets the specifications set forth therein. Recycled water use 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 alnendments,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 (BMPs)
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 SFR and MFR projected water use for
lower income areas separately.
• 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.

This section includes specific information on how the UWMP was developed, including efforts in
coordination and outreach.
�.1 F��sis �c��°I'laza �'����a��°��ic���
CWC 10617 requires that urban water suppliers with 3,000 or more service connections or
supplying 3,000 or more AF of water per year prepare an UWMP every five years.
10617 "Urban water supplier" means a supplier, either publicly, o�privately o�wned,
providing water for municipal purposes either directly o�indirectly to mo�e than 3,000
custome�s or supplying more than 3,000 acre feet of water annually. An u�ban water
supplier includes a supplier o� cont�actor fo� water; rega�dless of the hasis of�ight,
which distributes or sells for ultimate resale to customers. This pa�t applies only to
water supplied from public water systems...
2.1.1 �L�bli� ��t�r� Sys��z�ti
California Health and Safety Code 116275 (h) "Public Water Systein"ineans a system

To demonstrate the basis of reporting, the Public Water Systems services by the City are
listed in Submittal Tab1e 2-1. As listed in Section 2.5.1, Submittal Tab1e 2-1, the City
served one public water system with a total of 31,730 connections and a total of'7,411
million gallons (MG)in 2025.

The UWMP requires that the UWMP identify the water agency's coordination with appropriate
nearby agencies.
The City coordinated its e�forts with relevant agencies and parties to ensure that the data and issues
discussed in the plan are presented accurately. All water sources are shared in common with other
urban and agricultural interests in the area and as such, their participation in the process is a
valuable element in addressing the water needs of the Redding area.
?o�.[ �l�a�l�sa�� ���c� :I��;t�il C��>r�c�i�zc���
Retail agencies that receive a water supply from one or more wholesalers are required to
provide wholesalers with projected water demand from that source,in five-year increments
for 20 years. See Section 2.5.4 Submittal Table 2-4. This section is not applicable as the
City does not purchase water from an urban water wholesaler.

The City of Redding lies along the banks of the Sacramento River about 150 miles north of
Sacramento and 100 miles south of the Oregon border in the County of Shasta in Northern
California. It sits at the far northern end of the Sacramento Valley where the foothills meet the
Cascade Mountain Range. Mountains to the north, east and west surround Redding, which has an
average elevation of approximately 550 feet MSL. Figure 3-1 (following page) shows the physical
location of Redding and Shasta County. The City of Redding is one of three incorporated cities
within Shasta County and serves as the county seat. Water service is provided to residential,
commercial, industrial customers, and for fire protection services. The City and Shasta County
Map are located on the next page in Figure 3-1: Physical Location of Shasta County/City of
Redding.

The City of Redding began building its own water system in 1937 and was granted a water
permit by the State Board of Health on December 31, 1937. In 1941, the City purchased
the California Water Service Company, which had served portions of the City, and
integrated components of both operations into a citywide distribution system. In 1976, the
Enterprise Public Utility District (EPUD) and the Cascade Community Services District
(CCSD) were annexed into the City. The water systems from both these special districts,
which were supplied by groundwater wells, were integrated into the City's water system
with the construction of major cross-town transmission mains. Currently, the City serves
water to both City and county residents as per the Local Agency Formation Commission
(LAFCO) guidelines.
The City's service area is approximately 53 square miles and total population served is
approximately 90,254. Some areas of the City are served by neighboring districts, which
are shown in Figure 3-2 (following page). The City's water service area is located at the
northern end of the California's Central Valley and is along the Interstate 5 (I-5) corridor,
south of the City of Shasta Lake and north of the City of Anderson. The City supplies its
municipal water system from three primary sources: Surface water drawn from the
Sacramento River one-quarter mile upstream of the Diestelhorst Bridge and treated at the
Foothill Water Treatment P1ant (WTP) just south of Eureka Way; Surface water drawn
from Whiskeytown Lake through the Spring Creek Conduit to the Buckeye WTP in Old
Shasta; and Groundwater pumped from the Redding Area Groundwater Basin by seventeen
wells which are located primarily in the Enterprise pressure zone.

10630. It is the intention of the Legislature, in enacting this pa�t, to pe�init levels of water
inanageinent planning... �while accounting for impacts of climate change.
The City's service area climate is characterized by hot, dry summers and mild winters. Average
monthly evapotranspiration (ETo) rates, rainfall, and temperatures are summarized in Section
3.6.0, Surmnary Table 3-0.
As shown in Table 3-0, the Redding area has hot, dry summers and cool, rainy winters typical of
a Mediterranean-type climate. Summer temperatures over 100 °F and subfreezing winter
temperatures are common. Average annual precipitation from NOAA based yearly precipitation
from (1987-2025) is 32.08 inches and occurs mostly during winter months. About 75-90% of the
total rainfall falls between November lst and April 30th. Relative humidity is generally low to
moderate.

This section summarizes historical,current,and projected population trends in the City.Population
projections are essential to the planning process and help form the basis for planning decisions.
Projecting future growth is far from an exact science given the complex set of variables that can
affect the rate of growth. Normally, projections are developed by taking past patterns and
combining them with assumptions regarding the future to obtain an estimate of fut�ure growth as
well as guidance regarding future planning activities; therefore, such planning activities can only
be as effective as the ability to anticipate population growth.
3.�.I �erv�c� Ar�� �c�p�I�tic���
Redding was founded in 1872 and incorporated in 1887 at the northern terminus of the
California and Oregon Railroad. The City's early growth was stimulated by the railroad
and by the move of the county seat from Shasta in 1884. Mining played a major role in the
economic life of Redding around the turn of the century but declined as the twentieth
century progressed. In 1938, the construction of Shasta Dam provided another stimulus to
growth in Redding.The construction boom after World War II boosted the lumber industry,
which became the mainstay of Redding's economy.
Water demand over the last 50 years has increased greatly due to �xpansion of the service
area and development inside the City. One noteworthy expansion was the annexation of
the Enterprise area in November of 19'76. About 20,000 people were added to th� service
area. Once annexation occurred, per capita water consumption substantially decreased
14
a"���� ���1����.�I'� ��'��t°��°:���°� 1���,:��,="�t��;l�����.I�`��° ���,r�C�� I CITY OF REDDING
because the Enterprise region of the City was primarily residential with relatively sma11
irrigation and landscaping water demands. In more recent years, retail trade, construction,
and tourism have become more significant activities as lumber industry volumes have
declined.Redding has become a major regional center for shopping,health care, education,
and government.
The water service area for Redding was determined mainly by constraints such as: outlying
water district boundaries; Redding's contract boundaries with the United States Bureau of
Reclamation (Reclamation); natural boundaries such as rivers, ridges, and other
topographical features; the City's General Plan; and engineering considerations such as
pressure limits and supply limitations. Any further expansion would generally be an
encroachment into another water agency's jurisdiction where, in many cases, water system
facilities already exist. Because expansion beyond the service boundary is unlikely,
population growth and development inside the service area are the primary factors that will
determine future water consumption.
Selecting a population growth rate for the 2015 UWMP update presented challenges due
to the City's service area not matching the City Limit. Previously, population was
calculated by utilizing 3.2 persons per connection, but with the introduction of DWR's
Population Tool, the City was able to obtain a more accurate service area population
utilizing GIS mapping that led to a calculation of 3.31 persons per residential meter.
Because our recent historical current growth rate is now estimated at 0.6 percent looking
forward, from our 2023 Water Utility Master Plan, we are able to still use the same
multiplier of 3.31 persons per residential meter. At the end of 2025, residential water
meters totaled 27,267, which calculates the City's total service population (�using the 3.31
multiplier) to 90,254 water users. Utilizing historical data, growth in the Redding urban
area from 2025 to 2050 is expected to be 0.6 percent per year,resulting in a population of
approximately 103,792 in 2050. The current and projected population for the City's
service area is contained in Section 3.61 Submittal Table 3-1.

10631. Describe the service area of the supplier, including... othe�^social, economic,
and demog�aphic factors affecting the supplier's wate�management planning.
This section summarizes and analyzes demographics from 2010-2019 Census information
and more current available information from the 2020-2024 Census. Analyzing
demographic data can yield important information about possible shifts in demands for
City water service.
According to our established multiplier of 3.31, the total service population for the City
service area was 90,254 by the end of 2025. The median age in the City was 40.2(American
Community Survey), with the population being split 48.2 to 51.8 percent male to female,
respectively(US Bureau QuickFacts).
The California State Water Resources Control Board 2024 Medium Household Ineome
(Appendix C) shows that the California Median Household Ineome in 2024 was $99,122.

The median household income for the City in 2024 was $70,466, or 71 percent of the
statewide average (IJS Bureau QuickFacts). This defines the entire service area of the City
as a Disadvantaged Community.

10631(a). The description shall include the cur�ent 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 m�st
appropriate land use information, including, �where approp�iate, land use inforination�btained
from local or regional land autho�ities...
The General Plan identifies land use designations within major categories (sectors), which also
can be used to track water usage (see Figure 3-3: City of Redding Land Use map on the following
page). The City's service area water use is comprised of Single Family Residential, Multiple
Family Residential, Commercial/Institutional, Industrial, and unaccounted losses. In 2014, the
City subcontracted the customer services/billing software and stopped tracking statistics for the
Landscape/Recreational and Other Sectors.
• Residential Sector: The single largest sector of customers is the Residential Sector, which
includes both Single-Family and Multi-Family designations. Eight residential categories are
identified in the General Plan, and these provide for a full range of housing types for City
inhabitants.
• Commercial Sector: The General Plan incl�udes eight commercial land use designations:
Limited Office, General Office, Neighborhood Commercial, Shopping Center, Regional
Commercial, General Commercial, Mixed-use Care and I�eavy Commercial. These land-use
designations range from sma11, neighborhood-serving commercial projects to commercial
projects that are regional in scale. There is a mix of commercial customers, ranging from
markets,small restaurants,insurance offices,beauty shops, and gas stations to office buildings,
regional shopping centers, high-volume restaurants, and other facilities serving both the
permanent and visitor population.
� Industrial Sector: The General Plan includes two industrial designations: General Industry and
Heavy Industry. The Industrial land use classifications allow different types of warehousing,
manufacturing, or processing businesses to be located in appropriate areas by accommodating
a variety of manufacturing and employment activities ranging from small, employee-intensive
businesses to large, capital-intensive businesses.
� InstitutionaUGovernmental Sector: The City has a relatively stable institutionaU governmental
sector. Redding has become a major regional center for government (federal, state, and local),
healthcare, and education. This sector is expected to keep pace with the growth of the city.
The Commercial and Institutional/Governmental Sectors are quantified in the same category
by City customer services.

The UWMPA requires that the UWMP identify the quality 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.

Water demands served by the City are primarily Residential, including Single Family
Residential and Multiple Family Residential, Commercial/Institutional, and Industrial. The
Landscape Sector is included in the Commercial, Institutional and Industrial brackets
respectively. All connections in the City are metered. The following water use sectors and
associated meter deliveries, as shown in Submittal Table 4-1, were reported for the 2025
UWMP. 2025 City WateN Delivery data a�e in Appendix B.
The City classifies meters into the following categories: 27,26'7 residential (including SFR
and MFR),3,506 Commercial and Institutional, and 393 industrial. One Non-potable meter
existed until that service was discontinued in June of 2025. The actual demands for potable

water are presented in Submittal Table 4-1 for the 2025 calendar year. 2025 City Meter
Data are in Appendix B.
Submittal Table 4-2 contains the projected potable water demands from 2025 through
2050. The demand projections are based on the City's required conservation targets
as a Disadvantaged Community. However, the customer sector water deliveries in Table
4-2 are only general estimates of projected use and may vary significantly based on future
development and water conservation measures taken by each customer sector. Ultimately,
the implementation, magnitude, and type of future development will determine the
distribution of water use per customer sector.
The City total water demands for potable and non-potable water, future projections, and
recycled water demand, based on the figures presented in Submittal Tables 4-1, 4-2, and
6-4. The City provides recycled water to an irrigation customer, as described by Chapter 6.

No Optional Water-Use Sectors were included.
4.�.3 I�ast ����z �7s�
Overall, the past water use has been declining slowly since 2020 with a slight uptick in
2023. Past City Water P�oduction/Delive�y 2020-2024 data a�e included in Appendix B.

Projected water use is presented in 5-year estimates for years 2030 to 2050 and can be
viewed in Submittal Table 4-2.

Utilizing the upcoming reguired reductions of 1% as our projected water use, we
expect to meet these conditions most during most years. Dry years seem to increase
water usage as customers use more water to maintain their landscapes at a healthy
level and these sparse years may not meet estimated projections. See projected
water use in Submittal Table 4-2.

The City plans to update its ordinances to include the required non-functional turf
ordinance language before January 1, 2027, as required. The non-functional turf
ordinance should help to reduce overall water usage by one percent per year.
4,2.So� ���s�il C�a�l��
The City expects a majority of the projected"passive savings" to be from the non-
functional turf ordinance that will be implemented by the end of calendar year 2026.
The increasing cost of water will cause the rest of the "passive savings" that the
City expects to help meet the conservation targets.
4.2.5.5 �,����r-I�s�c�r�� I-���s��c�Ic�s
The UWMPA requires that the UWMP identify planned low-income housing
developments within the agency's service area and develop demand projections for
those units. A lower income household is defined as one with an income below 80
percent of area median income, adjusted for family size.
As shown in Table 4-3, lower income household demand projections are included
in the total water use proj ections (Table 4-4).
The Regional Housing Needs Assessment (RHNA) is mandated by State Housing
Law as part of the periodic process of updating local housing �lements of the
General Plan. The RHNA for the City of Redding for the 2018 to 2028 projection
period is 150 new housing units per year, for a nine-year total of 1,350 dwelling
units.This projection includes 56 extremely low-income units, 80 very low-income
units, 1281ow-income units, 100 moderate-income units, and 986 above moderate-

income units. It should also be noted, State legislation in 2017 made Accessory
Dwelling Units (AD� legal in all Cali�ornia cities. Homeowners can decide to
build either a detached ADU in their backyard, an attached ADU that is part of a
home addition, or an ADU conversion. Although the State has detennined ADU's
contribute no additional stress on utilities, the addition of another dwelling unit,
another family occupant, on a single-family property does impact water usage. (see
City of Redding General Plan Housing Element in Appendix I)

Distribution system water losses("real"losses)are the physical water losses from the water
distribution system and the supplier's storage facilities, up to the point of customer
consumption. The City's distribution system losses are quantified using the American
Water Works Association (AWWA) Method Guidance "Water Resources Water Audit
Manual." The distribution system water loss reporting for the years 2020-2024 are reported
in Submittal Table 4-5. The state standard was met for each of the last five years of water
loss audit reporting, with a11 annual audits completed and validated.

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 2020 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).
�01 SE3 �?-7 L��s�;�ic�� ��d 2�20 `�"ar�;ets
The purpose of this section in the 2025 UWMP is to determine whether the City has met the
20 percent conservation target. View results of the SB X7-7 in Submittal Table 5-L The City met
the 2020 Target in 2025.
A supplier may update the baseline and target water use if supplier has since gained access to more
reliable data than was available in 2020. These suppliers are required to submit an updated SB X7-
7 2025 Target Progress Form. With the introduction of the DWR Population Tool, the City was
able to more accurately determine the service area population. As a Disadvantaged Community
(DAC), the City is eligible to deduct process water from the GPCD calculation. This deduction
was overlooked in previous UWMPs and is included in the 2025 GPCD calculation. Therefore,
the target GPCD values are indicated on the updated SB X7-7Target Process Form and are utilized
in this UWMP to determine compliance with the 2020 Target.
In the Verification Form, a 10-year baseline and a 5-year baseline were calculated to establish the
minimum criteria for the City water use reduction targets. A summary of the 2008 total water
deliveries, 10-year baseline range (1999 to 2008), and 5-year baseline range (2004 to 2008) is
included in Table 1 of the SB X7-'7 Verification Forms (Appendix C)

If a Retail Supplier does not achieve its 2020 Target, the Retail Supplier is not eligible to
receive a water grant or loan from the State of California until it complies.
Two exceptions to this are provided:
• Water Code Section 10608.56(c) states that a Supplier shall be eligible for a water loan
or grant if it "has submitted to the department for approval a schedule, financing plan, and
budget, to be included in the grant or loan agreement, for achieving the per-capita
reductions."
• Water Code Section 10608.56(e) states that a Supplier can also be eligible for a water
loan or grant if it "has submitted to the department for approval documentation
demonstrating that its entire service area quali�es as a disadvantaged community."
The City now qualifies in two ways because it has met the 2020 Target and has submitted
and been approved that: its entire service area qualifies as a disadvantaged community.

The UWMPA requires that the UWMP include a description of the agency's existing and future
water supply sources �or 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.
F�,1 �'�t�� 5����Iy �lvc�mui��
The City's water supply is Whiskeytown Lake and the Sacramento River through a combination
of long-term (40-year) contracts with the USBR and long- and short-term agreements with
surrounding agencies and water suppliers. Water contracts and agreements are included in
Appendix D. Table 6-0 summarizes the annual entitlement under each contract/agreement. Each
contract/agreement is detailed separately below
6.�.� 5����i�I �c���w���,���t�c��a�
The special considerations the City briefly discusses in this Section are Climate Change
Effects,Regulatory Conditions, other Locally Applicable Criteria,while no Wholesale and
Retail Suppliers Coordination is required, and therefore not discussed further in this
section.
6.�.�.1 ���ir�at� �;l��r��;� �f��c���;
The CWC requires that suppliers consider climate change in their water supply analysis.
The potential water supply effects related to climate change are discussed briefly in this
section.
The IRWM Climate Change Vulnerability Assessment is included as Appendix E. No
vulnerabilities were identified for the category of Sea Level Rise.For the category of Water
Demand, it was noted that there are major industries that reguire cooling/process water,
and that City water use can vary by more than 50 percent seasonally. The City also
indicated that water use curtailment measures are effective. For the category of Water
Supply, the City indicated that a portion of the water supply is from snowmelt and that the
region has faced a drought in the past during which it was able to meet 1oca1 water demands.
Wildfires are a concern in the region, as noted in the Water Quality and Flooding
categories. For the category of Ecosystem and I�abitat Vulnerability, it was noted that the
region relies on aquatic or water-dependent habitats for recreation or other economic
activities and has rivers with quantified environmental flow requirements or known water
quality/quantity stressors to aquatic life. It was noted that hydropower is a source of
electricity in the region in the Hydropower category.
Beeause the City is generally 75 pereent reliant on surface water for its potable water
supply, many of the effects of climate change can be best summarized by considering the
effects of the entire region. These effeets will likely include:
30
a"���� ���1����.�I'� ��'��t°��°:���°� 1���,:��,="�t��;l�����.I�`��° ���,r�C�� I CITY OF REDDING
• Reduction in snowpack, which is significant source of water as it melts and feeds
both the Sacramento River and Whiskeytown Lake.
� Increase in intensity and frequency of extreme weather events.
• Effects on surface water levels during drought
• General decline in ecosystem health and function
� Changes to demand levels and patterns due to increasing temperatures.
As scientific understanding of climate change continues to advance, the nature of these
impacts and the impact on water supply availability and reliability will be thoroughly
studied to identify proper mitigation and adaptation strategies.
One additional consideration for the City is the impact of wildfires on water quality. The
wildfire season is typically followed by the rainy season and sometimes heavy
precipitation, leading to high levels of sediment in runoff that can severely degrade water
quality, such as the increase in turbidity levels. In addition, Per- and polyfluoroalkyl
substances (PFAS) is also an emerging contaminant that can be found in firefighting foam
that can stay and spread in the environment for decades and become a major contributor to
drinking water contamination. With the increasing frequency of wildfires and atmospheric
rivers across California, changes in treatment operations and/or treatment processes may
be necessary to reliably treat and maintain water service to customers experiencing back-
to-back impacts.

The new "Making Conservation a California Way of Life" regulations are requiring
Suppliers to modify their operations and reporting to meet Urban Water Use Objectives
(UWUO). This framework restricts water use beyond the 20% SB X7-7 reduction target.
As a Disadvantaged Community, the new regulation allows Redding to set a goal of one
percent (1%) reduction per year in overall GPCD. The City expects passive savings from
the Non-function Turf Ordinance (reguired in M�unicipal Code by January 1, 2027) and
reductions in water use due to rising water affordability pressures to provide substantial
savings. This will significantly help us reach the total 15% reduction required by 2040 as
a Disadvantaged Community.

A new agreement with the Sacramento River Settlement Contractors and Reclamation was
reached in 2024 to prevent the unprecedented 2022 Central Valley Project (CVP) water
allocation reductions from happening again. The "Drought Protection Program" structure
is laid out in the agreement found in Appendix D. It allows for cuts of up to 50% to be
made,preventing the severe cuts that hurt so many water users in 2022.As a"senior"water
rights holder, our cuts are generally not as severe as the"juniar"rights holders. Even when
the CVP water cuts are enacted, the City has a sufficient supply of water to fu1fi11 the
drought stage needs.

As required by the 2014 Sustainable Groundwater Management Act (SGMA), the two
medium priority sub-basins (Enterprise and Anderson) of the Redding Area Groundwater
Basin (RAGB) are managed by the Enterprise-Anderson Groundwater Sustainability
Agency (EAGSA). The City is one of six EAGSA members of the RAGB [As shown in
Figure 6].
The GSP has identified the RAGB as being a sustainable alluvial deposit, and as such no
legal pumping limit has been set—therefore, no overdraft mitigation efforts are currently
underway. Though no safe yield has been established for the RAGB, groundwater
modeling as part of the GSP development indicates that the RAGB is resilient to severe
drought conditions and is able to recover with one year of normal rainfall. There were no
limitations to pumping groundwater during the period 2021-2025, as groundwater wells
supplement the surface water supply and are used primarily to meet increased water
demand during the summer. During the spring, fall and winter months only a few wells out
of the seventeen are operated, since operating the surface WTPs is less costly and produces
higher water guality.
G.2,�.2 L3�si�� �'[�����;�a�a�z�t I���c�r�������c�n
The current Groundwater Sustainability Plan was submitted in 2022 and approved in
January, 2024. An updated GSP will be submitted to DWR by January 2027. During the
2021-2025 period, groundwater volumes were sufficient as a seasonal supplement to
surface water sources,providing approximately 25%of total annual water production(See
Table 6-1). Groundwater wells can supply enough water to supplement existing surface
water contracts with the Reclamation without any noted overdraft conditions in the 1oca1
groundwater basin(Bulletin 118 2003 Update for basin 5-6). In years of extreme drought,
a combination of increased and mandatory conservation measures and increased
groundwater pumping can aid in ensuring all customers have adequate water supply.

The sustainable yields for the Enterprise and Anderson subbasins are 24,439 and 29,001
MG or 75 and 89 Thousand Acre Feet. The well water is generally of very high quality
except for arsenic concentrations above the Primary 1Vlaximum Contaminant Level(MCL)
at Enterprise we11s EW-11 and EW-13, which are standby wells and have not been used
since 2008. Manganese levels are above the Secondary MCL of 50 ppb in all Enterprise
32
a"���� ���1����.�I'� ��'��t°��°:���°� 1���,:��,="�t��;l�����.I�`��° ���,r�C�� I CITY OF REDDING
and Cascade wells except EW-23, EW-09, EW-08, CW-08, and CW-01. As defined by the
United States Environmental Protection Agency (USEPA), a Primary MCL provides a
standard to protect public health while a Secondary MCL exists to prevent aesthetic issues
such as taste, color and odor. In Enterprise area wells, leaching from natural deposits can
result in dissolved manganese concentrations near or above the Secondary MCL and
requires treatment to avoid the black color that develops as inanganese precipitates out of
solution. Treatment consists of application of chemical sequestering agents which bind the
manganese in solution.None of the Cascade pressure zone wells require sequestration, and
iron levels above the Secondary MCL have not been encountered at any of the City's wells.
Due to detection of arsenic concentrations above the USEPA Primary MCL at wells EW-
11 and EW-13, these two wells have not been operated for water supply since 2008. The
permit status of wells EW-11 and EW-13 is designated as"Standby,"which limits pumping
to short-term emergencies of�ve consecutive days or less and for less than fifteen total
calendar days per year. Potential sources of arsenic contamination in general include
erosion of natural deposits, runoff from orchards, and glass and electronics production
wastes.
6.2.2.4 P�st Five; ����°� �����anc��v�te�° ��zx��p���
The Enterprise and Anderson subbasins provided the City with 10.183 billion gallons
(roughly 2 billion gallons per year) of water from seventeen wells during the years 2021-
2025. The wells range in depth from 170 feet to 600 feet and are run primarily during
periods of high water demand, especially in the months of June, July and August. The
return flow of groundwater to the river from the City's wastewater treatment facilities
contributes to water supplies for the Sacramento River environment and downstream users.
See Submittal Table 6-1: Groundwater Volume Pumped.
On August 13,2024,the State Water Resources Control Board,Division of Drinking Water
(Division), received a permit amendment application from the City of Redding reguesting
the inactivation of seven wells currently serving the City's domestic water system. The
wells are as follows: Enterprise Wells 03A, 04, 06A, 10, and 13 and Cascade Wells 06 and
09. These we11s were inactivated because they are no longer being used and would require
continuous monthly sampling to remain active. This reduced the total number of active
wells in the City's groundwater system to a total of ten active wells.

The City's sur�ace water supply is drawn from the Sacramento River and Whiskeytown
Lake (via the Spring Creek Conduit) through a combination of long-term contracts with
the USBR and long and short term agreements with surrounding agencies and water
suppliers (as detailed in Section 6.1). The USBR is responsible for the management of

treatment, and distribution facilities.

The City holds a long-term contract with the USBR (Contract No. 14-06-200-22871A-R-
1) that authorizes the City to divert from the Sacramento River a specified quantity of the
water supply created by the CVP. The contract was entered into April 1, 2005, and allows
the City to divert up to 6,843 MG (21,000 AF) annually. The contract as written expires
March 31, 2045, with provisions in the contract allowing far the renewal for successive
periods.
The City is required under the contract to prepare and implement a water conservation
program for all water diverted from the USBR sources. This program must be submitted to
USBR for approval every five years. The 2020 UWMP was submitted to USBR for review
and approval to satisfy this requirement. Upon completion, the 2025 UWMP and WSCP
will be submitted to USBR for review.
The contract states that USBR will use all reasonable means to prevent shortages in the
quantity of water available to the City. However, the contract also states that no liability
shall accrue against the United States if shortages occur d�ue to drought or other causes,
which are beyond the control of the United States. During drought conditions, CVP
diversions can be cut back significantly, as was the case in 2015 when they were reduced
by 25 percent. The percent reduction is applied to the historical average of the City's actual
water usage over the prior three unconstrained water years.
Currently the City only uses about 60 percent of the USBR allocation during an average
year. However,during drought years,this allocation can be reduced drastically. The USBR
water year is from March to February of the following year. In 2016, 2017, 2018, 2019,
and 2020, the allocation was 100 percent (6,843 MG). In 2021 and 2022, reductions were
25 percent and 82 percent respectively. Stage Two of the WSCP was initiated. Voluntary
Stage One operations resumed in April of 2023 after winter storms refilled Shasta Lake
Reservoir. 2023, 2024 and 2025 were all at 100 percent allocation.
Because the reductions in 2002 were so unprecedented, and have been rectified with the
Drought Protection Plan agreement,we are still using the 2012-2016 drought reductions as
a more historically accurate example of realistically reduced allocations that could happen
in the future.

River through the Spring Creek Conduit and Toyon Pipeline a specified quantity of the
water supply created by the CVP. The contract was entered into on Mareh 1, 2005 and
allows the City to divert up to 1,991 iVIG (6,110 AF) annually. The con�ract as originally
35
a"���� ���1����.�I'� ��'��t°��°:���°� 1���,:��,="�t��;l�����.I�`��° ���,r�C�� I CITY OF REDDING
written was to expire on February 28, 2045, with provisions in the contract allowing for
the renewal for successive period. Per the Water Infrastructure Improvement for the Nation
Act of 2016 (WIIN Act), the Conversion Contract Amendment was finalized in August
2020 and does not carry an expiration date.
The City is required under the contract to prepare and implement a water conservation
program for all water diverted from the USBR sources. This program must be submitted to
USBR for approval every five years. The 2020 UWMP was submitted to USBR for review
and approval to satisfy this requirement. Upon completion, the 2025 UWMP and WSCP
will be submitted to USBR for review.
The contract states that USBR wi11 use a11 reasonable means to prevent shortages in the
quantity of water available to the City. However, the contract also states that no liability
shall accrue against the United States if shortages occur due to drought or other causes,
which are beyond the control of the United States. During drought conditions, CVP
diversions can be cut back significantly, as was the case in 2015 when they were reduced
by 75 percent. The percent reduction is applied to the historical average of the City's actual
water usage over the prior three unconstrained water years.
Currently the City uses 100 percent of the USBR allocation during an average year.
However,during drought years,this allocation can be reduced drastically.The USBR water
year is from March to February of the following year. In 2016, 2017, 2018, and 2019 the
allocation was 100 percent (1,991 MG). In 2020 and 2021, the allocation was 75 percent
based on the average water usage over the prior three unconstrained years, resulting in
approximately 1,559 MG available to the City in the 2020 and 2021. 2022 saw
unprecedented allocation reductions of 100 percent.

The City owns and operates two wastewater treatment plants that collect and treat
wastewater within the service area,both of which are considered tertiary treatment
facilities: Stillwater Wastewater Treatment Plant (SWWTP) and Clear Creek
Wastewater Treatment Plant(CCWWTP). Therefore,the City coordinates recycled
water use within the service area and does not rely on an outside facility or agency.

Wastewater from the Redding area west of the Sacramento River is collected and
treated at the CCWWTP, situated along the western shore of the Sacramento River
at the southern boundary of the City's service area (see Figure 3-2). Total Infl�uent
received 3,142 MG. In 2025,the treatment facility discharged effluent at an annual
average rate of 8.16 MGD, and the effluent total suspended solids (TSS)
concentration of the wastewater averaged 4.1 mg/L (236 lbs./day). Total recycled
water used for landscape irrigation and wash down purposes at the treatment site
was 163 MG. No expansion of reclaimed water usage is anticipated in the future.
All treated effluent that is not used is discharged to the Sacramento River.
Wastewater from the Redding area east of the Sacramento River is collected and
treated at the SWWTP, situated at the southern extreme of the City's service area
along the Sacramento River's northern shore (see Figu�e 3-2). Total Influent

an annual average rate of 3.89 MGD, with effluent total suspended solids (TSS)
averaging 2.5 mg/L(841bs./day). Total recycled water used for landscape irrigation
and wash down purposes on-site was 158 MG. Recycled water used for crop
irrigation is permitted under Waste Discharge Requirement #98-016 and volume
delivered was 17 MG in 2025.No expansion of reclaimed water usage is anticipated
in the future. All treated effluent that is not used is discharged to the Sacramento

The wastewater treatment plants service areas include mostly residential and
commercial customers with a sma11 number of industrial clients. A wastewater
pretreatment program monitors industrial and commercial enterprises to ensure that
toxic substances, pollutants, and wastewater discharged to the collection system

The City's two WWTP provide advanced secondary treatment of wastewater. The
treatment system consists of screening, activated sludge aeration, secondary
clari�cation, cloth/sand media filtration, and chemical disinfection using chlorine
gas. A combined 16'7.63 million gallons (MG) of emergency retention storage is
available for excess influent flow or partially treated wastewater. A11 treated
effl�uent that is not used by reclaimed water customers is discharged to the
Sacramento River. Sl�udge processing consists of an aerobic digestion and
dewatering by centrifuge. Dewatered bio solids is currently hauled to a landfill for
disposal.
The 2025 wastewater flows from the City's service area is summarized in Table 6-

At the present time, the City does not foresee any opportunities far the use of desalinated
water, including ocean water, brackish ocean water, and brackish groundwater, as a long-
term supply since the City is located in the Sacramento Valley approximately 150 miles
from the Pacific Ocean. In addition, there is no brackish water in the RGWB and both the
Sacramento River and Whiskeytown Lake are fresh water sources. Therefore, no
opportunity exists from use of desalination water as a future water supply.

Water exchanges require 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. The City has one water
exchange,with the McConnell Foundation for the SP Pumphouse water. This water
is deducted from McConnell's water right with Reclamation and is no longer
deducted as use from the City.

The UWMPA requires that suppliers describe water supply projects and programs that may
be undertaken to meet the projected water demands.
The Pump Station 1 project will be to replace the existing pumphouse on the Sacramento
River, which has served the area for over 85 years. The new Pump Station 1 will be
relocated a quarter mile upstream from where it currently sits on the south side of the
Sacramento River just west of the Diestelhorst Bridge. The plan is to have it operational
and online sometime in 2030. While this doesn't increase our overall water supply, it
certainly increases our water reliability. The A.C.I.D. dam will not have to be installed to
be able to operate the pumphouse at maximum capacity, as is the current situation. The
dam is usually installed before April 1 and taken out after the irrigation season ends in
October.
Water conservation measures outlined in this plan wi11 reduce future consumption and
postpone the need for new supply sources. In 2007, the City completed an expansion of
the Buckeye Water Treatment P1ant(WTP) from 7 MGD to 14 MGD capacity, facilitating
meeting increased summer water demands in the Buckeye area. This expansion, coupled
with renegotiated Reclamation contracts, gives the City the option of taking the Foothill
WTP completely offline for maintenance during low-demand winter months. Table 6-7
summarizes planned future water proj ects.

required to produce and distribute their water supply. Water energy intensity is the total amount of
energy on a per million gallon basis associated with water management processes occurring within
the City's operational controL The City has selected to report its energy intensity using the total
utility approach Option B. In 2025, the City produced 7,4ll MG of water within its service area.
The kilowatt hours (kWh) of energy needed across the City's potable water system was 9,800,860

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 single-dry year and in a five-consecutive-year
drought.
10635 (a) Every url�an water supplier shall include, as part of its u�ban water management
plan, an assessment of the �eliability of its water se�vice to its custoiners during normal, dry,
and inultiple dry water years. This wate�supply and demand assessmentshall compa�e the total

assessinent shall be based upon the information compiled pursuant to Section 10631, including
available data from state, regional, or local agency population projections within the se�vice
area of the urban wate�supplier.
The City of Redding is a United States Bureau of Reclamation (Reclamation) contractor and
receives water from the Central Valley Project (CVP) under two separate agreements.
In 1966, the City entered into a long-term supply contract with the Reclamation, with an initial
term from April 1964 to March 3 l, 2004. The"Redding Contract", one of a group of Reclamation
supply contracts generally referred to as "Settlement Contracts," was intended to resolve legal
water rights conflicts that arose between "senior" pre-1914 water rights holders along the
Sacramento River and the Reclamation following completion of the CVP. In 2005, the "Redding
Contract" was extended for another forty years, until March 31, 2045. The "Redding Contract"
supply is allocated into two classi�cations—Base supply of 5,818 MG per year and Project supply
of 1,026 MG per year.
In 1971, the City entered into the original `Buckeye Contract" with the Reclamation, which
assigned the Buckeye Service Area (Buckeye) to the City and made available CVP supply to the
City to serve the Buckeye area. Amendments to the `Buckeye Contract" were made in 1990 and
again in 1994. The 1994 amended Buckeye Contract governs the supply to the City's Buckeye
Water Treatment Plant,which came online in 1995. In 2005,the`Buckeye Contract"was extended
another forty years until February 28, 2045. Per the Water Infrastructure Improvement for the
Nation Act of 2016 (WIIN Act), the Conversion Contract Amendment was finalized in August
2020 and does not carry an expiration date. The `Buckeye Contract"provides the City with 1,991
MG of Project water.
In addition to the two surface water contracts with the Reclamation, the City has two groundwater
supply sources, the Enterprise we11 field and the Cascade well field. The Enterprise well field
provides most of the City's groundwater, while the Caseade well field provides a relatively minor
loeal supply to the southern end of the Cascade service area only. These well fields are located

a"���� ���1����.�I'� ��'��t°��°:���°� 1���,:��,="�t��;l�����.I�`��° ���,r�C�� I CITY OF REDDING
within the Redding Area Groundwater Basin (RAGB) which is deeined to be approximately 510
square miles in size, and which can provide a considerable augmented supply (see aerial map of
RGWB, Fig.6).
The Shasta County Water Agency performed groundwater modeling as part of development of the
Redding Area Groundwater Management planning process. Modeling conditions of the 1930's
California drought coupled with 2025 projected demand; the aquifer was able to recover with just
one year of normal rainfall—leading to the conclusion that the RAGB (5-6) is very resilient and
able to meet all reasonably expected demand. (See Section 6.3 Groundwater)
Table 7-0 contains a summary of factors affecting water supply reliability and that may pose an
opportunity for inconsistency in supply. Legal and environinental factors represent supply
restrictions that lnay be imposed due to downstream water temperature, CWP issues, quality, and
quantity objectives. Climatic factors represent potential restrictions due to drought conditions.

10631 (b)(1) A detailed discussion of anticipated supply availability under a normal wate�
year single d�^y year, and droughts lasting at least five years, as well as more frequent and
seve�e periods of drought, as described in the d�ought risk assessment. For� each source of
wate�supply, consider any inf'ormation pertinent to the reliahility analysis conducted pur.ruant
to Section 10635, including change.r in supply due to climate change.
There are two aspects of supply reliability that can be eonsidered. The first relates to immediate
serviee needs and is primarily a funetion of the availability and adequacy of the supply facilities.
54
a"���� ���1����.�I'� ��'��t°��°:���°� 1���,:��,="�t��;l�����.I�`��° ���,r�C�� I CITY OF REDDING
The second aspect is climate-related and involves the availability of water during mild or severe
drought periods.
There are a variety of factors that can affect water supply reliability. The factors that might result
in supply reliability issues include water quality and climatic changes.
'7.1,1 �at�z4 S��a��ly ���1i�y
The UWMPA requires that the UWMP include a discussion of water quality impacts on
the reliability of an agency's water supplies.
The water quality from the Sacramento River, Whiskeytown Lake, and the RAGB is very
good. Whiskeytown Lake is most vulnerable to contaminants from recreational activities.
Water quality does not have a significant effect on water management strategies or
supply reliability due to the high quality of the surface water supply. The City's drinking
water meets all applicable water quality regulations.
The Annual Consumer Confidence Report (CCR) for the City's service area in year 2025
can be found in Appendix K.
?.�.2 �l�r����� t�1�a��;�
Climate change is likely to add uncertainties to supply planning and future supply
availability. The severe and prolonged drought from 2012 to 2016, and the shorter and
more severe drought in 2021-2023, was a test of the City's ability to prepare for, and adapt
to, the effects of climate change. Considering reductions in per capita use and projected
demands, the City continues to balance a cautious optimism with a long-term strategy for
sustainable sources of supply.
As stated in Chapter 4, the altered climate patterns in California creating hotter days and
longer heat waves will increase customer water use and evaporative water losses. Extended
drought periods are expected to become both more frequent, and more severe,which could
lead to reduced rainfall and snowpack. �Iigher temperatures and decreased precipitation
will result in drought,making wildfires more frequent,more severe, and harder to fight due
to hotter and drier conditions in the forests with less water supplies.Wildfires, followed by
potential flooding, mean more landslides and mudslides, further impacting water supply
reliability. Creating defensible space as well as slope stabilization and erosion prevention
near critical infrastructure will be important for preserving supplies.
Efficient use of water is paramount in the City's �ffort to adapt to climate change.
Technology and equipment to appropriately monitor and manage water supplies will be
critical. Ensuring that aging and leaky pipes are replaced and upgraded to minimize water
loss is equally important. Redundancy in source of supply wi11 provide operational
flexibility in the event supplies are interrupted by fire, floods, earthquakes, or drought.
Climate change effects such as drought, wildfire, and temperature fluctuations may a11
contribute to a degradation of water quality over time.

Unfortunately, short-term contracts are very insecure from the standpoint of reliability and
cost fluctuations. Two existing out-of-service wells may be rehabilitated when needed, but
probably not before 2030. These wells will provide a reliable additional supply in an area
in which the City is growing and supplement the Sacramento River and Whiskeytown Lake
sources.
However, given the long-term contract amount with USBR (even when allocations are
reduced), coupled with utilizing water from the RGWB, supply is sufficient to meet current
and future City demands. The City will continue to evaluate opportunities and potential
alternative sources to improve the reliability of the water supply

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.
7.2.1 ���� ���z�T°��e C;��a�������z��tic�r�
Since the majority of the City's water supply in future years will come from the Sacramento
River and Whiskeytown Lake, seasonal and climatic changes will impact the availability
of water. Historical curtailments in the City's supply occurred during drought years. The
specific years identified for normal, single-dry, and five-consecutive-year drought
presented in Tab1e 7-1 were developed based on available historical records for the City.
Whi1e the City has experienced severe drought in years past, Table 7-1 reflects the most
recent dry years and projections going forward. As in the 2015 UWMP, the year 2005 was
selected as an average year as it had no supply reduction requirements, and the year 2014
was selected for the single-dry year because it represents the lowest reasonable water
supply available in recent years. Table 7-1 reflects recent years of drought (2014-2018),
where the City had the lowest average water supply available for five consecutive years.
Table 7-1 contains the actual water supply that was available for each year, with a
percentage of the average water year that occurred in 2005.
"7.�.I.l "I'y�a�s c�f�c��r�
The year-types that must be included in the WSRA are:
� Normal Year: a year, or an averaged range of years, that most closely represents
the average water supply available to the City.
� Sin 1�.�: the year that represents the lowest water supply available to the
City.
� Five-Consecutive-Year Drou�: the period that represents the five-year historical
drought sequence for the City. The DRA requires analysis based on the driest five
year historieal seguence for the City.

The projected demand and supplies are compared in 5-year increments in Table 7-2, Table
7-3, and Table 7-4. The demand is based on the total water use from Table 4-3. The supply
is based on the reasonably available volume from Table 6-9. The supply is adjusted by the
percent of average supply for the year type.
7.2.2.1 �Ic>r����i Yc�r
During an average water year, a combined delivery of up to 14,057 MG of water is
available to the City utilizing its USBR contracts and well production. However,
the City typically uses 60 percent of its available supply.Future cit�vide demands,
assuming the City can meet the water use targets, will not exceed the supplies.
Table 7-2 provides an estimate of the projected normal year supply and demand
totals.
�,2.2.� �ir��1� II��� �`e,��°
During a single-dry year, the USBR allotments can be reduced by 25 percent ar
more. 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.
°�.2.2,� �`z�� C"c��4��,�ative �)ry �c;�rs
The multiple-dry year supplies were developed based on the DWR Sacramento
Valley runoff tables and available water supply data.Table 7-4 provides an estimate
of the projected five-consecutive-year drought supply and demand totals. Demand
reductions due to water shartage stage rationing measures are not included in the

surface water supply. In extreme situations, we would purchase additional water supplies
from local (e.g. McConnell Foundation) or regional water rights holders.

CWC Section 10635(b)was 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 1oca1 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 DRA from 2021 through 2025 is summarized in Table 7-5.
The supply is based on the USBR's health and safety allocation amount for the City and the existing
water contract with ACID. Therefore, there is sufficient supply to meet projected demands within
the next five years. Use reduction savings are not quantified in Tab1e 7-5 (refer to Tab1e 8-3)

replacing the water shortage contingency analysis under former law. The new requirements are
more prescriptive to have consistency throughout California. The WSCP document is now separate

not limited to the time of year, weather forecasts, temperature, experience and economic
feasibility, the volume of water available through allocations, volume available from
groundwater wells, and guality of the water produced from each source.
The City Manager can declare a water supply emergency exists based on:
l. Major water line breaks, or pump or system failures occur, which cause unexpected
loss of capability to provide water service; or
2. Surface water supply curtailments imposed by the regulatory authority; or
3. Natural or man-made contamination of the water supply source(s); or

The Stages 2 through 6 criteria are based on running average of the seven-day water demand
expressed as a percentage of the water system safe operating capacity and/or enforcing
mandatory water use restrictions imposed by the State of California. Stage 1 Conservation
Measures are in effect regardless of any calculation of supply or demand.
�.3 Si� �t�r�����°d ����r ���c���a�e, L,�v�Is
The City's WSCP details the actions to be taken during a reduction in available water supply.
These actions are broken up based upon six possible stages of water shortage.Reductions in supply
are most frequently associated with drought, but could also be the result of flooding, major fire
emergencies, earthquakes, regional power outages, water contamination, and any other situation
that could impact the water supply.
The goal of a WSCP is to have a procedure for managing and mitigating shortages allowing the
City to respond in an efficient and timely manner.Water shortage response actions include demand
reduction, supply augmentation, operational changes, and mandatory prohibitions to address
shortage levels. The following sections summarize the City's water shortage stages and the
measures employed during each stage, as outlined in the WSCP.

The stages of action in response to water supply shortages, including greater than 50 percent
reduction in water supply are summarized in Table 8-1. Detailed descriptions of each stage of
action are included in the WSCP (Appendix J).

In a drought year or in a water emergency, if projected surface water supplies are
approaching or estimated below our current supply or a WSCP stage 2 or greater is
initiated,then we would purchase our full contract option with A.C.I.D. We have a contract
through 2045 to purchase up to a total of 1,303 MG (4,000 AF). We would also rely more
on our groundwater well system to help reduce our surface water demand. In extreme
situations, we would purchase water from other local or regional water rights holders.
We would also expand our public information campaign and reduce hydrant flushing to
help augment the water supply.
8.4.2 Demand Reduction
On May 9, 2016, the Governor of California issued an Executive Order declaring the
following practices be permanently prohibited:
• Hosing off sidewalks, driveways, and other hardscapes.
• Washing automobiles with hoses not equipped with a shut-off nozzle.
• Using non-recirculated water in a fountain or other decorative water feature.
• Watering lawns in a manner that causes runoff, or within 48 hours after measurable
precipitation.
• Irrigating ornamental turf on public street medians.
The City has several demand-reduction measures ready to implement as respond actions to
address the shortage levels. Demand reduction actions such as public education outreach
campaigns, water-use prohibitions such as outdoor irrigation restrictions by day, time of
day, and other outdoor use restrictions are listed in Table $-3. As the shortage level
increases, so do the response actions.
�.�-.:� (�p��°�ti���l C��a����s
Operational changes for a non-catastrophic water shortage may be initiated to control local
sections of the water system to prevent or reduce large volumes of water 1oss.
�.�.4 �1ddi����t�1 ������tc�ry 12��tr�c.t�c�r�s
The City has mandatory restrictions for reducing customer usage because it is associated
with enforcement actions and penalties. Mandatory restrictions include limitations on
outdoor water use timing, restricting certain types of outdoor residential water use,
restrictions on using water for certain outdoor functions, and other restrictions. See Table
8-3.

The City Water Utility's Emergency Response Plan is located in Appendix D.
�.4.f� S�is��i� �2i�;�� �ss�s�r��e;a�t ��d Nlat��at�c�l� �l�ra
The City's Local Hazard Mitigation Plan includes a seismic risk and vulnerability
assessment and is included as an Appendix G. The objective of the seismic risk and
vulnerability assessment was to provide the City with an overview of seismic
vulnerabilities related to the water system facilities and identify recommendations for the
mitigation of those vulnerabilities to minimize system disruption.
�.4.7 �hc�����c �2�s��ca��� �.��ic�z� �"ft���iv����ss
For each specific shortage response action identified in the plan, the WSCP must also
estimate the extent to which that action will reduce the gap between supplies and uses.
Essentially, the purpose of this section of the WSCP is to demonstrate to the Supplier's
satisfaction that a given suite of shortage response actions can be expected to deliver the
expected outcomes necessary to meet the requirements of a given shortage level.
Given the difficulty of accurately quantifying demand-reduction benefits resulting from
specific water shortage response actions, it is important to understand current water-use
patterns and how demand changes in response to various economic, environmental, and
social variables. Estimates for each specific shortage response action identi�ed in the plan
are given in Table 8-3.

The City relies upon Codified Ordinances adopted in the Redding Municipal Code to enforce the
WSCP. The WSCP can be found in Title 14 Chapter 9 - Water Shortage Contingency Plan. Any
violation of this chapter shall be enforced utilizing administrative processes and remedies set forth
in Chapter 1.13, Chapter 1.14, or Chapter 1.15 of the Redding Municipal Code.

The anticipated �inancial consequences to the City of implementing the WSCP shortage
response actions are fiscal impacts. The City will face potential reductions in revenue and
increased expenses associated with implementation of the shortage enforcement response
actions described in the WSCP. Fiscal impacts may include, but are not limited to:
� Reduced revenue from reduced water use under the WSCP lev�l.
� Increased staff costs for tracking, reporting, and enforcement.
• Economic impacts associated with water dependent businesses in the Supplier's
service area.
� Impacts of reduced flows on related water utilities (e.g., wastewater collection
systems,recyeled water).

Mitigation actions needed to address revenue reductions and expense increases associated
with activated shortage response actions described in this section may include, but are not
limited to:
• Using financial reserves.
• Reducing operation and maintenance expenses.
• Deferring capital improvement projects.
• Reducing future projected operation and maintenance expenses.
• Increasing any t"ixed readiness-to-serve charge.
• Increasing any cominodity charge and water adjustment rates to cover revenue shortfalls.

Enforcing excessive water use would be more costly than the fines associated with the
penalties. So any enforcement actions for excessive use will cause increased financial costs
on top of the loss of revenue from less water being sold. The City does not use rate
structures or excessive water use ordinances as we are a Disadvantaged Community, and
this would only hurt customers who may be using less water and end up being charged
more for less water.
�.9 �(��i�c�rir�� ��� �2��e��-t����;
Monitoring and reporting key water-use metrics is fundamental to water supply planning and
management.Monitoring is also essential to ensure that the response actions are actually achieving
their intended water-use reduction or if improvements or new actions need to be considered. The
City reports to the State Water Board monthly, and as such, would only be able to check to see if
overall water use reductions are meeting the WSCP stage reduction percentages on a month by
month basis.

The City's WSCP is prepared and implemented using an adaptive management approach. Using
the results of its monitoring and reporting program, described in Section 8.9, to evaluate the need
for, and proced�ures to revise its WSCP. The WSCP is a dynamic tool that is the subject of
refinements as needed to ensure that its shortage response actions are effective and to produce the
desired results. If certain procedural refinements or new actions are identified by City staff, or
suggested by customers or other interested parties, the City ineorporates them into the WSCP, and
implements them during the five-year update adoption process at the appropriate water shortage
level.

NOTES:
10632 (a) Every urban water supplier shall prepare and adopt a water shortage contingency
plan as part of its urban water management plan that consists of each of the following
elements:
(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. Shortage levels shall also apply to
catastrophic interruption of water supplies, including, but not limited to, a regional power
outage,an earthquake, and other potential emergency events.
(B)An urban water supplier with an existing water shortage contingency plan that uses
different water shortage levels may comply with the requirement in subparagraph (A) by
developing and including a cross-reference relating its existing categories to the six standard
water shortage levels.

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. In addition, the
City has several drought-specific stages that can be implemented if water supplies become limited
and the need for more intensive water conservation becomes necessary.
As a United States Bureau of Reclamation contractar, the City of Redding is required by the
Central Valley Project Improvement Act (CVPIA) of 1992, Public 1aw 102-575, Section 3045(e)
to develop and implement a Federal Water Management Plan (FWMP) that includes Best
Management Practices (BMP) developed by the California Urban Water Conservation Council
(CUWCC). The current required update of the City's progress towards full implementation is
being prepared concurrently with this Urban Water Management Plan (IJWMP).
The FWMP is an essential element of the City's contractual CUWCC obligations with the
Reclamation and the City is required to complete the CUWCC annual report,which includes B1VIP
reporting. This report, completed annually by signatories to the CUWCC Memorandum of
Understanding (MOU) and by Reclamation contractors, defines implementation requirements for
Municipal and Industrial BMPs or DM�Ms. For the purposes of responding to the UWMPA and as

This DMM involves adoption of an ordinance prohibiting water waste. The City Municipal Code
contains the Water Shortage Contingency Plan Ordinance (Chapter 14.09) (see Appendix J). This
Water Shortage Contingency Plan Ordinance is always in place and is not dependent upon a water
shortage for implementation. See Chapter 8 and the WSCP (Appendix � for detailed information
on stages of action, prohibitions of end uses, and penalties.

Installing water meters and billing for actual water use provides a strong incentive
for customers to use less water and equalizes service cost for each customer to their
actual use (high water users would pay a more equitable share of the system costs).
Water metering can reduce exterior landscape water use and can also achieve a
modest reduction in interior water use. All of the City customers are metered and
billed volumetrically.
9.1.�.3 C�c�r���rv��ti�r� �rzei���,
Water conservation is encouraged through the pricing system that rewards
customers who use less water with �nancial incentives, with higher water users
being charged more based off the volume of water used. While conservation pricing
isn't done by a tiered rate structure, the volume of water consumed determines the
amount of a customer's bill, and the less water consumed the less the bill will
effectively be. Furthermore, the City has established administrative fines and
penalties associated with violated provisions of the current Water Shortage
Contingency Plan Ordinance (Appendix J, Section 7.2)
The City already had annually increased volumetric water rates established through
January 1,2023 coming into this update and initiated another round starting January
1, 2024 through 2027. Water rate increases occurred every year from 2021 through
2025.

Examples for public education and outreach far water demand management can
include coordination with other agencies and provision of programs promoting
water conservation, speakers for the media or community groups, school education
programs, public service announcements, water conservation bi11 inserts,
information booths at public events,websites,online tools, social media,newspaper
articles, and daily water use comparisons on customer's water bi11s.
The City has implemented this DMM through the provision of flyers/brochures to
customers, as well as providing bill inserts/bi11 messaging promoting water
conservation,providing information on the City website, and providing tours of
the WTP and WWTP.
The City is continually updating its website to include relevant and user friendly
information and resources like the Water Smart Gardening platform at

This DMM focuses on the water distribution system itself, and includes water
audits, leak detection, and repair. The first step in a water audit is relatively
straightforward, involving comparison of the amount of water produced with the
amount of water delivered to customers. The difference is termed "unaccounted
water," which incl�udes actual losses (leaks) in the distribution system, authorized
but unmetered use (e.g.,hydrant flushing and�re�ghting),unauthorized water use,
and meter error.
The City has completed and submitted results of the AWWA Water Loss Audits
and loss control for a11 of the last five years. The entire City is metered which allows
the City to routinely calculate water losses.
Because our system has such high water pressure, distribution leaks tends to show
themselves by surfacing or quickly eroding the pipe to become large enough to
detect relatively easy. Between City staff and the public reporting our Water
Distribution Crew are repairing leaks continually. We triage service leaks by
severity.The bigger the leak,the faster it gets repaired. This helps to conserve water
and prevent even greater water loss.
When a complaint is lodged regarding a potential water leak, the City takes swift
action to identify and repair the given leak as warranted. The City provides onsite
leak detection assistance for customers, for public systems and private plumbing.
Work Orders are generated when a customer calls requesting assistance. A Utility
Customer Service Worker visits the site and tries to isolate the leak if possible. If
appropriate, repairs to the public system are made and recommendations are given

regarding private plumbing and irrigation systems. Customers are shown how to
read their water meter and how to check for leaks.
The best way to evaluate the effectiveness of this program is to compare water
production data at the WTP with water consumption from the City's customers. To
improve the effectiveness, the City should continue to review data and identify
leaks for repair,per�orm an annual review of the Water Loss Audits information to
determine if a fu11-scale system audit is warranted, make improvements when able,
and perform distribution leak detection when warranted and cost-effective.
