A RESOLUTION OF THE CITY COUNCIL OF THE CITY OF
REDLANDS, APPROVING THE WATER SUPPLY ASSESSMENT FOR
CONCEPT PLAN NO. 7
THE CITY COUNCIL OF THE CITY OF REDLANDS DOES HEREBY RESOLVE AS
FOLLOWS.
Section 1. The City Council does hereby find and determine as follows:
a. In accordance with the East Valley Corridor Specific Plan, a Concept Plan
("Concept Plan No. 7") allowing development of that certain property bounded by San
Bernardino Boulevard to the south, Texas Street to the east, Pioneer Avenue to the north, and
Interstate 215 to the west, has been proposed by Investment Development Services.
b. The approximate eastern half of this property is known as the `Trojan
Groves site, and the approximate western half of the property is known as the `Redlands
Commons site.
c. In addition, a Development Plan has been proposed regarding the
Redlands Commons site. The Development Plan would allow 205 single-family detached
dwelling units, 20,000 square feet of single -story office space, 85,500 square feet of retail space,
4.3 acres of open space, and 1.2 acres of parkland (the `Redlands Commons development").
d. Because the Redlands Commons development is located in the same
`development envelope under the East Valley Corridor Specific Plan as the Trojan Groves site,
it is desirable that Concept Plan No. 7 and its environmental impact documentation prepared
under the California Environmental Quality Act ("CEQA') also analyze the potential
development of the Trojan Groves site.
e. Water Code Section 10910 et seq ("SB 610") requires the preparation of a
`Water Supply Assessment' for any project of a specified size, including a mixed-use project
that would consume the equivalent amount of water as a 500 -dwelling unit development.
f. Because the Trojan Groves site has been assumed for the purposes of
CEQA analysis to allow the development of 345,100 square feet of mixed general commercial
uses, the development of Trojan Groves and Redlands Commons would exceed the water
demand of a 500 -dwelling unit development and thus requires the preparation of a Water Supply
Assessment.
g. The City of Redlands Municipal Utilities Department has proceeded to
prepare the Water Supply Assessment attached hereto as Exhibit A (the `Concept Plan No. 7
WSA'), as required by SB 610.
Section 2 The City Council does hereby further find and determine as follows
a The Concept Plan No 7 WSA contains an analysis of historic and
projected water supplies utilized by the City, the entitlements and rights to each water source, the
financing, approvals and permits necessary to obtain and convey projected amounts of water, and
the reliability of each water source
b The Concept Plan No 7 WSA contains an analysis of future demands with
and without the Redlands Commons and Trojan Groves developments
c The Concept Plan No 7 WSA is in full compliance with the content
requirements of SB 610
d The Concept Plan No 7 WSA assesses the adequacy of water supplies to
meet projected demands of the City and of the development under Concept Plan No 7 for a
twenty-year projection, in normal, single -dry, and multiple -dry years, and concludes that
supplies will be adequate
e The analysis and conclusions of the Concept Plan No 7 WSA are
supported by substantial evidence contained in the WSA and the documents cited and referenced
therein
Section 3 Based upon the foregoing, the City Council resolves the following.
a Approve and adopt the Concept Plan No 7 WSA
b Direct the Community Development Director to incorporate the WSA into
the Environmental Impact Report being prepared for Concept Plan No 7, as per SB 610
ADOPTED, SIGNED AND APPROVED this 1st day of August, 2006.

WATER SUPPLY ASSESSMENT
Concept Plan No. 7
I. Introduction
The population growth expected for the next twenty years in the State of California is projected
to result in additional demands on water systems. In order to prevent future water shortages
due to growth, the Legislature has enacted laws to ensure the increased demands are adequately
addressed and that a reliable source of water supply is available prior to approval of certain new
development. This legislation includes Senate Bill 610 ("SB 610") (Water Code Section 10910 et
seq.), which seeks to promote more collaborative planning regarding water supplies on the part
of cities and counties by requiring detailed information on water availability to be provided prior
to the approval of certain specified large land use development projects.
SB 610 requires a city or county to identify any public water system that may supply water to a
large development project and to request that public water system to prepare a Water Supply
Assessment ("WSA'). A WSA must include, among other information, a comparison of water
supplies and demands for a twenty-year projection in normal, single -dry year and multiple -dry
year hydrological scenarios; an identification of existing water supply entitlements, water rights,
or water service contracts relevant to the identified water supply for the proposed project; the
amount of water received in prior years pursuant to those entitlements, rights, and contracts;
and information relating to the reliability of projected water sources and infrastructure. The
statute also encourages the incorporation of information from the local water agency s current
Urban Water Management Plan ("UWMP"), in which water agencies assess future water
supplies and demands for a twenty-year projection, and which are required to be reviewed and
revised every five years. Once completed, the WSA must be considered and incorporated into
the project Environmental Impact Report ("EIR").
The Concept Plan for the Redlands Commons and Trojan Groves developments (collectively
`Concept Plan No. 7' or 'the Project") covers a portion of the City of Redlands, California.
Specifically Concept Plan No. 7 covers approximately 68 acres bounded by Interstate 210 to the
west, San Bernardino Avenue to the south, Texas Street to the east, and Pioneer Avenue to the
north. Redlands Commons is located on approximately 36 acres and will consist of 205 single-
family detached dwelling units, 20,000 square feet of single -story office space, 85,500 square
feet of retail space, 4.3 acres of open space, and 1.2 acres of parkland (resulting in 5.5 acres of
total open space). The balance of the 68 acres consists of land to be included in Concept Plan
No. 7 for the Trojan Groves development, which it is assumed for the purposes of this analysis
would be developed with mixed general commercial uses, with buildings covering 25% of the
site for approximately 345,100 total square feet of building space (10,890 square feet of building
space per acre).
LOSAI\162049 7
SB 610 applies to mixed use projects that consume an amount of water equivalent to that
consumed by a 500 -dwelling unit project. Since Redlands Commons in conjunction with the
development of Trojan Groves would exceed the water usage of a 500 -dwelling unit project, SB
610 is applicable and the following WSA has been prepared. However it should be noted that
the assessment of SB 610 applicability does not take into account existing water use, such as the
agricultural water use on the Redlands Commons development site (which results in the
Redlands Commons portion of the overall Project actually using less water in the future than it
does now see Table 10 below).
I1. Supply
The bulk of the City of Redlands and its associated sphere of influence is served by the City of
Redlands Water Utility (a small section of the southeastern portion of the City is served by the
Western Heights Mutual Water Company). The City receives water from the San Bernardino
and Yucaipa Groundwater Basins, surface water from the Santa Ana River Watershed, surface
water from the Mill Creek Watershed, and water imported by the State Water Project.
Recycled water from the City s Water Reclamation Plant is also used. The following is a more
comprehensive discussion of each of these sources, based upon a review of the information
contained in the 2005 City of Redlands UWMP ("2005 UWMP") and other sources.
Groundwater
The San Bernardino Basin
Water Code Section 10910(d)(I). The assessment required by this section shall include an
identification of any existing water supply entitlements, water rights, or water service
contracts relevant to the identified water supply for the proposed project, and a description of
the quantities of water received in prior years by the public water system under the
existing water supply entitlements, water rights, or water service contracts.
Water Code Section 10910(d)(2) An identification of existing water supply entitlements,
water rights, or water service contracts held by the public water system shall be
demonstrated by providing information related to all of the following: (A) Written contracts
or other proof of entitlement to an identified water supply
Water Code Section 10910(D. If a water supply assessment for a proposed project includes
groundwater the following additional information shall be included in the water supply
assessment: (2) A description of any groundwater basin or basins from which the
proposed project will be supplied. For those basins for which a court or the board has
adjudicated the rights to pump groundwater a copy of the order or decree adopted by the
court or the board and a description of the amount of groundwater the public water system
has the legal right to pump under the order or decree. For basins that have not been
adjudicated, 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 bulletin of the department that characterizes the
condition of the groundwater basin, and a detailed description by the public water system, or
the city or county if either is required to comply with this part pursuant to subdivision (b), of
the efforts being undertaken in the basin or basins to eliminate the long-term overdraft
condition.
The San Bernardino Basin is a large groundwater basin that has been estimated to contain as
much as 2,000,000 acre-feet (AF) of accessible water The basin is bounded by consolidated
rocks of the San Gabriel Mountains, San Bernardino Mountains, and Crafton Hills, and by several
faults. The southern boundary is the Banning fault, the eastern boundary is the Redlands fault,
the northern boundary is roughly the San Andreas fault, the northwestern boundary is the Glen
Helen fault, and the southwestern boundary is the San Jacinto fault. The Santa Ana River Mill
Creek, and Lytle Creek are the main tributary streams in the basin. Recharge in the basin has
historically resulted from infiltration of runoff from the San Gabriel and San Bernardino
Mountains. The Santa Ana River Mill Creek, and Lytle Creek contribute more than 60 percent
of the total recharge to the groundwater system. Lesser contributors include Cajon Creek, San
Timoteo Creek, and most of the creeks flowing southward out of the San Bernardino
Mountains. The basin is also replenished by deep percolation of water from precipitation and
resulting runoff, percolation from delivered water and water spread in streambeds and
spreading grounds. (Department of Water Resources ("DWR") Bulletin 1 18).
Rights to pump water from the San Bernardino Basin were determined in 1969 through a judicial
water adjudication, Western Municipal Water District of Riverside County et al. v East San
Bernardino County Water District et al. Riverside County Superior Court, Case No. 78426. The
watermaster under the adjudication judgment (which is known as the 'Western Judgment, see
Appendix A) has established the annual safe yield of the San Bernardino Basin at 232,100 AF -year
(AFY). Under the Western Judgment, the City and other local users may pump as much water
as needed. However any pumping beyond the safe yield must be recharged back into the San
Bernardino Basin by the San Bernardino Valley Municipal Water District ("SBVMWD") using
water from an outside source (typically water imports from the State Water Project) or
additional captured water from local surface water sources. Thus, as long as SBVMWD is able
to procure replacement water from the State Water Project, the City may effectively pump as
much water as needed from the San Bernardino Basin. In addition, it should be noted that the
Western Judgment does not require same year replacement of groundwater pumped beyond
the safe yield; rather the watermaster allows overpumping in times of drought and restocking of
groundwater supplies during wet years, when State Water Project supplies are at normal or
above -normal levels and aquifer replenishment water may be purchased.
According to the SBVMWD the basin is in a technical state of overdraft, in that the total amount
of extractions last year exceeded the annual safe yield. (Conversation with Mr Sam Fuller of
SBVMWD• Annual Report of the Western -San Bernardino Watermaster Table No. 17 )
However the SBVMWD has accumulated a large balance of water recharge credits due to
groundwater recharge over the years. Even though more water was extracted than was
naturally replaced, the amount of extra water already recharged and in the basin is more than
enough to `balance the basin s water budget. (Annual Report of the Western -San Bernardino
LOSAI\162049.7 3
Watermaster Table No. 17.) As mentioned above, it is anticipated that recharging and drawing
down will occur in different years, and the Western Judgment specifically allows this by requiring
that the watermaster examine water extraction and recharge in five-year periods. Thus,
although currently in a state of technical overdraft, the management of the basin by the Western
Judgment watermaster ensures that water levels are not adversely affected.
Water Code Section 10910(D. If a water supply assessment for a proposed project includes
groundwater the following additional information shall be included in the water supply
assessment: (3) A detailed description and analysis of the amount and location of
groundwater pumped by the public water system, or the city or county if either is required to
comply with this part pursuant to subdivision (b), for the past five years from any groundwater
basin from which the proposed project will be supplied. The description and analysis shall be
based on information that is reasonably available, including, but not limited to, historic use
records. (4) A detailed description and analysis of the amount and location of groundwater
that is projected to be pumped by the public water system, or the city or county if either is
required to comply with this part pursuant to subdivision (b), from any basin from which the
proposed project will be supplied. The description and analysis shall be based on information
that is reasonably available, including, but not limited to, historic use records.
The City utilizes up to 20 wells in the San Bernardino Basin to provide water to its customers.
Past and future pumping levels are detailed in Table I and Table 2. Please note that the figures
in Tables I and 2 are not the total supply of San Bernardino Basin groundwater to which the City
has access. Rather these figures are only the amounts actually pumped or that are projected to
be pumped to meet customer demands. See Table 7 for figures relating to the total
groundwater supply available to the City at various points in the future. Wells extracting water
from the San Bernardino Basin are located in Redlands, Mentone, and Calimesa (the eastern and
central areas of the basin).

Currently the City is able to extract 37,000 AFY from the San Bernardino Basin.' The City
expects that an additional 8,000 AFY could be produced from the San Bernardino Basin after the
re-establishment of the existing Texas Street well field using tailored granular -activated carbon
treatment for ammonium perchlorate (` perchlorate'). This project is being undertaken after a
five-year pilot program in cooperation with Pennsylvania State University and is pending receipt
of a permit from the California Department of Health Services ("CDHS") for this treatment
process. Approval of this permit is expected in 2006 or 2007 Other approvals and permits
necessary to implement this project may include CEQA and land use approvals, as well as the
issuance of building permits. The well field re-establishment may be financed through the
normal City budget for the Municipal Utilities Department, the sale of municipal or Proposition
50 bonds, the securing of loans and grants from the state revolving fund and the California
Infrastructure and Economic Development Bank, or some combination thereof. No further
infrastructure work is necessary to provide the projected water supplies from the San
Bernardino Basin, excepting that for routine replacement or maintenance of facilities. Financing
of the replacement and maintenance of facilities will be included in the normal City budget for
the Municipal Utilities Department. Appendix B to this WSA is the City s Major Capital
Improvement Program from its '2004 Water and Wastewater Cost of Service Rate Study
which shows the funding in 2005 of the Texas Street well field re-establishment.

court or the board and a description of the amount of groundwater the public water system
has the legal right to pump under the order or decree. For basins that have not been
adjudicated, 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 bulletin of the department that characterizes the
condition of the groundwater basin, and a detailed description by the public water system, or
the city or county if either is required to comply with this part pursuant to subdivision (b), of
the efforts being undertaken in the basin or basins to eliminate the long-term overdraft
condition.
The Yucaipa Basin underlies the southeast portion of the San Bernardino Valley and is bounded
on the north by the San Andreas fault, on the west by the Redlands fault and the Crafton Hills,
on the south by the Banning fault, and on the east by the Yucaipa Hills. This portion of the San
Bernardino Valley is drained by Oak Glen, Wilson, and Yucaipa Creeks south and west into San
Timoteo Wash, which is a tributary to the Santa Ana River Dominant recharge to the basin is
from percolation of precipitation and infiltration within the channels of overlying streams,
particularly Yucaipa and Oak Glen Creeks, underflow from the fractures within the surrounding
bedrock beneath the basin, and artificial recharge at spreading grounds. (DWR Bulletin 1 18).
The City s common law appropriative rights to Yucaipa Basin groundwater arise due to the
City's ownership of mutual stock in the South Mountain Water Company a private water
company The Yucaipa Basin has not been subject to a water adjudication, and groundwater
production there is currently limited only by the common law water rights of the various entities
and individuals pumping water The basin is currently in a state of overdraft. The Yucaipa Valley
Water District ("YVWD") is involved with the development of a groundwater management plan
under Assembly Bill 3030. Formulation and adoption of a groundwater management plan would
result in the implementation of replenishment practices in order to stabilize water levels. Only if
groundwater recharge is not capable of completely stabilizing water levels may a groundwater
management plan limit the pumping of groundwater Participation in a groundwater
management plan is voluntary While the City may participate in a groundwater management
plan in the Yucaipa Basin for the purposes of increasing recharge, the City believes that its rights
may be prior to those of other users in the Yucaipa Basin. If this is the case, it is likely that these
reductions would not be applied to the City Rather pumping by other entities would be
reduced in order to stabilize water levels (again, this would occur only in the case that recharge
activities do not completely address the overdraft problem). If the City s rights are not prior
rights, it may be subject to pumping reductions in order to help eliminate the overdraft
condition. In either case, the implementation of a groundwater management plan would result
in a stabilization of groundwater levels. Because the 2005 UWMP projected 1,000 AFY of
pumping from the Yucaipa Basin, this analysis will continue to use this assumption. However
even if the City s rights to pump from the Yucaipa Basin were completely eliminated (not a likely
scenario), the City has more than enough surplus water in the driest of years (e.g. a surplus of
8,648 AF of water supply in the third year of a drought in 2030, see Table 17 below) to replace
the lost Yucaipa Basin groundwater

Although there are tentative plans to reclaim an unused well in the basin to supply potable
water increases in supply due to this well are contingent upon future groundwater management
activities and are not included in this Water Supply Assessment. The City has no other plans to

expand the number of wells or its infrastructure in the Yucaipa Basin, and thus no further
financing, permits, or approvals are required to secure and convey this water supply The only
work regarding water supplies from the Yucaipa Basin that would need to be done would be
routine replacement or maintenance of facilities. Financing for replacement and maintenance of
facilities will be included in the normal City budget for the Municipal Utilities Department.

The City exercises rights to the surface waters of the Santa Ana River and Mill Creek watersheds
as an appropriator under common law (Conference with Mr Douglas Headrick, Chief of
Water Resources, City of Redlands, May 9 2006.) The City has a pre -1914 right to divert
44.7% of the flow of the Mill Creek watershed, as well as private water company stock, which
translates to the City being entitled to a high flow rate of 25 cubic feet per second
(approximately 18,000 AFY). Water from the Mill Creek watershed is treated at the Henry Tate
Water Treatment Plant ("Tate WTP") on Highway 38, east of Mentone. Because the Tate WTP
is limited to 14.9 mgd in treatment capacity the City is effectively limited to receiving
approximately 16,690 AFY from Mill Creek.
Rights to diversions in the Santa Ana River watershed exist through the City s ownership of Bear
Valley Mutual Water Company stock, as well as independent pre -1914 appropriative rights and
ownership of other private water company stock. Altogether the City currently has rights to 14
million gallons per day in the Santa Ana River watershed, corresponding to an annual available
entitlement of approximately 15,680 AFY Water from the Santa Ana River watershed is treated
at the Horace Hinckley Water Treatment Plant ("Hinckley WTP"), which has a capacity of 14
mgd and is located north of Mentone. The amount of surface water produced from each of the
watersheds in recent years is described in Table 5, below

Future Santa Ana River water diversions are expected to be raised to 18 mgd (approximately
20,160 AFY) by 2015, due to an expansion of the Hinckley WTP and the purchase of additional
private water company stock. This expansion may require CEQA and land use approvals,
building permits, and the approval of the California Department of Health Services. The
expansion may be financed through the normal City budget for the Municipal Utilities
Department, the sale of municipal or Proposition 50 bonds, the securing of loans and grants
from the state revolving fund and the California Infrastructure and Economic Development
Bank, or some combination thereof. Additionally work would need to be done regarding the
routine replacement or maintenance of facilities. Financing for replacement and maintenance of
facilities would also be included in the normal City budget for the Municipal Utilities
Department. Appendix B, the City s Major Capital Improvement Program, contains an estimate
to 2014 of the cost and timing of various major capital improvement programs, including the
design phase of the Hinckley WTP expansion (line item 43).

The City purchases imported State Water Project water from the SBVMWD Compared with
other jurisdictions, the amount of imported water required by the City is modest, and is
projected to remain constant at 5,000 AFY through the twenty-year span of this analysis. (See
2005 UWMP Table 3-1 ) SBVMWD does not contract with water customers, such as the City
LOSA1\162049.7 9
Rather pursuant to SBVMWD Resolution No. 888 (see Appendix C), the SBVMWD requires
customers to submit applications for water service. The City has been able to receive imported
water from SBVMWD since the opening of SBVMWD's transmission line to the State Water
Project in the 1970s (no State Water Project purchases were made previous to 2003, due to a
lack of demand on the part of the City). The City is free to request as much imported water
from SBVMWD as it requires; conversely the City is not entitled to a minimum amount of water
from SBVMWD. Rather imported water purchases are subject to availability Historic State
Water Project purchases by the City are listed below in Table 6.

The City currently makes use of 7,000 AFY of recycled water treated at the City s Water
Reclamation Plant ('WRP"). The recycled water is created from wastewater from City
residents and is wholly owned by the City thereby constituting a reliable source of water for
non -potable uses. The City projects that recycled water usage will increase from 7,000 AFY in
2005 to 9,000 AFY in 2030. This increase will occur due to additional users of recycled water
coming online and increases in treatment capacity planned for the WRP Although the 2005
UWMP projected usage of reclaimed water in 2005, no reclaimed water has been delivered
previous to the current year (2006) due to delays in initiating service. These delays have been
overcome and the City is currently supplying reclaimed water from its WRP
Water Code Section 10910(d)(2) An identification of existing water supply entitlements,
water rights, or water service contracts held by the public water system, or the city or county
if either is required to comply with this part pursuant to subdivision (b), shall be demonstrated
by providing information related to all of the following- (8) Copies of a capital outlay

system. (C) Federal, state, and local permits for construction of necessary infrastructure
associated with delivering the water supply (D) Any necessary regulatory approvals that are
required in order to be able to convey or deliver the water supply
The expansion of the WRP's capacity will occur in stages, necessitating approval of amendments
to the existing Santa Ana Regional Water Quality Control Board ("RWQCB") permit for
increases in capacity treatment, as well as potentially obtaining CEQA, land use, and building
permit approvals. Also, distribution pipelines would require installation, which will frequently be
the responsibility of developers as a part of entitlement conditions of approval. The incremental
expansion of the reclaimed water distribution system would require amendments to the existing
CDHS permit, as well as City building and encroachment permits. The expansion of this
infrastructure may be financed through the normal City budget for the Municipal Utilities
Department, the sale of municipal or Proposition 50 bonds, the securing of loans and grants
from the state revolving fund and the California Infrastructure and Economic Development
Bank, or some combination thereof. Additionally routine replacement or maintenance of
facilities would be required. Financing for replacement and maintenance of facilities will be
included in the normal City budget for the Municipal Utilities Department. Appendix B, the
City's Major Capital Improvement Program, shows the projected cost and timing of various
WRP upgrades (listed as 'WWTP Upgrade Projects in the table), including the second phase of

In addition to a potable water supply from groundwater wells, the City also utilizes non -potable
groundwater to meet irrigation and other such needs. Currently these wells are dedicated
exclusively to irrigation. However it is the goal of the City to unify the non -potable water
distribution system such that reclaimed water and non -potable groundwater are transmitted
through the same pipelines. Non -potable groundwater is produced from the San Bernardino
Basin (see discussion above). Consequently the previous discussion as to water entitlements is
equally applicable here. Historic non -potable groundwater production is included in the figures
contained in Table I
Water Code Section 10910(d)(2) An identification of existing water supply entitlements,
water rights, or water service contracts held by the public water system, or the city or county
if either is required to comply with this part pursuant to subdivision (b), shall be demonstrated

system. (C) Federal, state, and local permits for construction of necessary infrastructure
associated with delivering the water supply (D) Any necessary regulatory approvals that are
required in order to be able to convey or deliver the water supply
The City is also planning on expanding the pumping and usage of non -potable groundwater
from 4,500 AFY in 2005 to 12,000 AFY in 2030. Achieving this increase will require the
expansion of the City's non -potable water distribution system, as well as the potential addition
of new wells or the re -activation of old wells. The expansion of the distribution system would
be constructed by the City and by developers (as part of their project conditions of approval),
and would require CEQA review and the issuance of building permits by the City and
potentially the issuance of permits by CDHS. The addition of new wells or the re -activation of
old wells would also potentially require approval by CDHS. These improvements may be
financed through the normal City budget for the Municipal Utilities Department, the sale of
municipal or Proposition 50 bonds, the securing of loans and grants from the state revolving fund
and the California Infrastructure and Economic Development Bank, or some combination
thereof. Additionally routine replacement or maintenance of facilities would be required.

No recycled water was available in 2005, due to delays in system comp etion. As of 2006, recycled water is now
available.
Supply Reliability & Projection of Overall Supplies
Water Code Section 10910(f). If a water supply for a proposed project includes groundwater
the following additional information shall be included in the water supply assessment: (5) An
analysis of the sufficiency of the groundwater from the basin or basins from which the
proposed project will be supplied to meet the projected water demand associated with the
proposed project.
Overall, the City's water supplies are highly reliable. Groundwater is the largest portion of the
City s water budget, with local surface water diversions only slightly less significant.
Groundwater is a reliable source due to the management of the San Bernardino Basin by the
Western Judgment and the court-appointed watermaster and the fact that this basin supplies the
vast majority of the City's need for groundwater Additionally it should be noted that the
projected pumping figures contained in Tables 2 and 4 represent utilization of only about 50% of
the City s current groundwater supply as reflected in the figures for Table 7 above. Thus, the
City is projected to retain a surplus of groundwater supply capacity and even though the
Yucaipa Basin is overdrafted, the City has enough water supply in the San Bernardino Basin to
meet its needs by utilizing just that basin, should City entitlements to the Yucaipa Basin be
reduced through a water adjudication or implementation of a groundwater management plan.
LOSA1\162049.7

Groundwater supplies would be affected by drought, however In the City's historical
experience, in single -dry year droughts the ability to pump groundwater at normal levels would
not be affected, nor would this be the case during the first and second years of a multiple -dry
year drought. (Conference with Douglas Headrick, Chief of Water Resources, City of Redlands,
May 24 2006, based upon analysis of internal Department of Municipal Utilities hydrographs).
However groundwater supplies are projected to be reduced by 20% in the third year of a
multiple -dry year drought. This climatic variation is equally applicable to potable and non -
potable groundwater supplies. The variation is supported by examination of City hydrographs
showing well water levels at all City wells dating as far back as 1960, which indicate that water
levels do not begin to drop until the area is several years into a multiple -dry year drought. The
City is located in the upper portion of the San Bernardino Basin, near where percolating water
from the San Bernardino Mountains enters the basin, resulting in large amounts of water that is
slow to move to the lower portion of the basin. Thus, City wells still experience high water
levels during the initial periods of drought because percolated storm water from previous years
has not yet moved out of the upper portion of the basin. In addition, crevices created by
earthquake faults at the foot of the San Bernardino Mountains store storm water and snowmelt
and gradually recharge this water into the San Bernardino Basin over the course of several years,
further dampening the effect of a multiple -dry year drought. Because of the City's large surplus
of available groundwater even after taking into account the reduction in groundwater supplies
due to drought, there would still be enough water to meet the demand for groundwater the
City is projecting. (See Tables 2 and 4 for projections of the actual amount of groundwater that
will be pumped in the future to meet customer demand).
In addition, groundwater quality issues will not affect the reliability of this supply Wells in the
San Bernardino Basin, in the northwest portion of the City were previously affected by a plume
of trichloroethylene ("TCE") contamination. This plume has moved away from the City and no
longer affects those wells. A plume of perchlorate contamination in the San Bernardino Basin is
currently affecting wells in the northern portion of the City One ion -exchange treatment unit is
currently treating groundwater from this area in order to provide potable water As previously -
mentioned, the City is also close to obtaining a permit for operation of new perchlorate
treatment technology at the Texas Street well field. These existing and imminent treatment
facilities will be adequate to allow the production of the amounts of groundwater predicted in
this WSA.
Surface water is more subject to climatic variation than groundwater According to past
experience, the City projects that there would be a 15% decrease in surface water supplies in
single -dry year droughts and in the first year of a multiple -dry year drought. Surface water
supplies will drop by 30% in the second year and 50% in the third year of a multiple -dry year
drought, respectively as compared with normal year supply levels. Surface water sources are
affected more quickly by drought than groundwater because, although the discharge of storm
water and snowmelt from saturated crevices cushions surface supplies from immediate, large
decreases in supply surface water moves more quickly out of the area as compared to
groundwater (in a matter of days and not years). Thus, once the saturated crevices have been
completely drained, surface supplies are affected to a larger extent than groundwater supplies.
LOSAI\162049.7

Recycled water supplies are not expected to be affected by climatic variation, since even during
droughts the wastewater from which recycled water is obtained will continue to be generated
by water users. Imported water supplies from the State Water Project are the most susceptible
to variation due to year-to-year climate changes. The City's wholesaler of State Water Project
water SBVMWD has indicated that during droughts water imports could decrease to 5% of
normal. The reliability of supply from the State Water Project is described by DWR in The State
Water Project Delivery Reliability Report 2005 (DWR, November 2005). The analysis performed
by DWR indicates that for a single -dry year drought, supplies could diminish as much as 95% as
compared to normal years. Reliability for multiple -dry year droughts was concluded to be
better however The worst case scenario was assumed for all dry years (i.e. import deliveries
during dry years will only total 5% of normal) to provide a conservative assumption of water
supply in this WSA.2 In order to quantify the effect of dry years, please see Table 8, which
provides projected supplies in 2030 during normal, single -dry and multiple -dry drought years.

2 Actually the Reliability Report estimate of 5% reliability in a single -dry year is acknowledged to be lower (more
conservative) than the reliability experienced in the 1977 drought upon which the single -dry year scenario is based.
This is due to the fact that 1977 was the driest year in the 80 -year record, the simulation did not allow for carry-
over of previous wet year supplies (as would happen in reality), and a conservative assumption was utilized
concerning the amount of water in major reservoirs DWR must preserve in storage, even in times of drought.
DWR recognizes that in a realistic single -dry year reprising 1977 conditions reliability could range from 596 to 2096.
However the most conservative figure is used in this WSA.
L0SA1\162049.7 15
Method of Demand Projection
Base future demands in this analysis were taken from demand projections contained in the City
of Redlands 2005 UWMP These projections were derived from population projections.
Population data indicates that growth could potentially occur in the 9% range in the first five-
year increment and diminish to 5% for the next three five-year increments, until 2025.
Population projections also indicate that the 2025 to 2030 time period would see an increase of
3%. Aside from water demands attributable to growth, the City also consumes water through
the usage of non -potable water (for irrigation, for instance), recycled water and unaccounted-
for system losses. These water uses are also accounted for in the demand projections.
Table 9 illustrates normal year water demand based upon these projections.

In times of drought, the City has a Water Shortage Contingency Plan ("WSCP") that may be
implemented in four action stages, ranging from voluntary to mandatory compliance, with
enforcement and penalties for violations committed during periods of mandatory compliance.
Additionally increases in water rates would lead to conservation of water supplies. Further
information concerning the contents of the WSCP are contained in Section 7 of the 2005
UWMP
Based upon prior historical experience, the City expects that any increased demand during a
single -dry year drought will be offset by the implementation of its WSCP• thus, demands are
assumed to be 100% of normal. Similarly although multiple -dry year droughts would naturally
be expected to increase landscaping demands, the City expects that implementation of the
WSCP will counter this by implementing measures preventing excessive irrigation runoff,
requiring the adjustment of sprinkler and irrigation systems to prevent waste, and allowing
irrigation only on an irrigation day designated by the City and prohibiting irrigation between the
hours of 12 P.M. and 8 P.M. (See 2005 UWMP page 7-4). Measures such as these and other
contained in the WSCP are expected to keep total demand equal to normal year levels, if not
less.
Future Project Demand

The Redlands Commons development consists of 205 single-family detached dwelling units,
20,000 square feet of single -story office space, 85,500 square feet of neighborhood inline retail
space, 4.3 acres of open space, and I.2 acres of parkland (a combined total of 5.5 acres of open
space). Daily water usage of this development would be 78,011 gallons per day (` gpd"),
resulting in an annual water demand of 87 AFY However the Redlands Commons site
presently uses 94,090 gpd in irrigation water due to the citrus orchard onsite, for a total of 105
AFY Taking current water usage into account, the development of Redlands Commons would
actually result in an onsite demand reduction of 18 AFY See Table 10, below

For the purposes of this WSA, agricultural water use is based upon City demand factors. However actual water
usage onsite in 2005 totaled 149 AF Thus, the figure of 105 AFY represents an extremely conservative analytical
projection.
The development of Trojan Groves, however would result in an increase in water demands
being generated at that site. This is due to the fact that Trojan Groves is currently vacant, with
no water usage onsite. According to City water demand factors, the Trojan Groves
development would result in an increase in water demand of 45 AFY See Table I 1 below

For the purposes of this WSA, and in order to yield a conservative analysis, water usage from
existing onsite agricultural irrigation that is to be discontinued is not subtracted from the demand
projections for the overall Project. Thus, the overall Project, including both Redlands Commons
and Trojan Groves, would result in water demands of 132 AFY See Table 12, below
(Appendix D to this WSA contains an analysis of water demands and supplies that takes into
account the discontinuation of existing onsite water demands.)

the time period from 2005 to 2030, in times of both normal years, single -dry year droughts, and
multiple -dry year droughts. As demonstrated in these tables, the City will meet all projected
demands, including those of the Project, in all scenarios between now and 2030.

V Conclusion
The previous analysis identifies and describes the sources of water upon which the City of
Redlands will rely to meet existing and future demands. The City does not rely to a significant
degree on imported water but rather obtains the bulk of its water from groundwater basins and
surface waters to which the City has long-standing appropriative rights. Groundwater supplies
are of special importance, as the City is authorized to pump as much water as it requires and the
availability of this supply particularly the San Bernardino Basin, ensures that there is an excess of
supply as compared to future demands. The water demand of the Redlands Commons
development, the Trojan Groves development, and the overall Project are calculated in Tables
10 through 12. Table 12 shows that the overall Project would result in 132 AFY in water
demand (application of an agricultural water credit due to existing onsite usage would lower the
total net water usage to only 18 AFY see Appendix D). Furthermore, the demands of the
Trojan Grove development have been added to City water demands from the UWMP in this
WSA, but since that development is consistent with the General Plan and East Valley Corridor
Specific Plan, its water demands may have already been included in the UWMP thus producing
an even more conservative analysis. In addition, the Redlands Commons development is
proposed to occur on a site for which development was proposed in the East Valley Corridor
Specific Plan as well, and thus some water demands for the site were already included in the
UWMP although this is assumed to not be the case in this WSA in order to yield a more
conservative analysis. Tables 13 through 17 demonstrate that the City s supplies are adequate
to meet all existing and future demands, in addition to the demands of the Project, till the year
2030, including during single -dry year and multiple -dry year droughts.
