Plaintiff and appellant County of Sacramento (County) appeals from the trial 

court’s grant of summary judgment in favor of defendant and respondent Department of 

Water Resources (DWR).

In 2019, the County filed a complaint for injunctive relief alleging that DWR 

failed to obtain county permits before conducting geotechnical exploration activities 

related to a state water infrastructure project in the Delta region of Sacramento County. 

The County noted that its ordinance required all persons, including the state, to obtain 

county permits before conducting activities including drilling exploratory holes and 

borings. The County contended that it adopted its ordinance pursuant to division 7, 

chapter 10 of the Water Code,1 and the Legislature had expressly waived the state’s 

sovereign immunity with respect to the chapter’s provisions. (§§ 13050, subd. (c); 

13755.)

DWR moved for summary judgment. It asserted that, as a state agency acting 

within its governmental capacity, it is immune from local regulations except where the 

Legislature expressly waived that immunity. DWR further contended that its activities 

did not fall within the scope of chapter 10, which is a limited statute governing “wells,” 

“water wells,” “cathodic protection wells,” and “geothermal heat exchange wells” as 

those terms are defined in the chapter. (§§ 13710-13713.) The trial court granted the 

motion, concluding DWR’s exploration activities did not fall within the scope of chapter 

10, and the County was not authorized to expand its regulatory authority over the state 

beyond that which was expressly authorized by the Legislature.

 Further references to chapter 10 are to division 7, chapter 10 of the Water Code, and 

further undesignated statutory references are to the Water Code.
3

The County challenges the trial court’s ruling. It contends the scope of the 

Legislature’s waiver of sovereign immunity extends beyond activities expressly defined 

in chapter 10 to include activities governed by an administrative bulletin establishing 

drilling and boring standards that the Legislature referenced in chapter 10. (§ 13801, 

subd. (c).) Alternatively, the County argues that various statements made by DWR 

created a triable issue of fact as to whether DWR’s exploration activities fall within the 

scope of activities expressly defined by chapter 10. Finally, the County challenges 

multiple evidentiary rulings made by the trial court.

In the published portion of our opinion, we conclude the scope of the Legislature’s 

waiver of the state’s immunity extended only to the activities expressly defined in chapter 

10. In the unpublished portion of our opinion, we agree with DWR that the County failed 

to establish a genuine dispute of material fact as to whether DWR’s exploration activities 

fall within the scope of chapter 10 as we construe it, and also conclude that the County 

has failed to demonstrate prejudice from the trial court’s evidentiary rulings, even if we 

were to assume error. Accordingly, we affirm the judgment.

FACTS AND PROCEEDINGS

The following facts are taken from the evidence set forth in the papers filed in 

connection with the summary judgment motion, except that to which objections were 

properly made and sustained. (Yanowitz v. L’Oreal USA, Inc. (2005) 36 Cal.4th 1028, 

1037.) We summarize the evidence in the light most favorable to the County, the party 

opposing summary judgment, resolving any doubts concerning the evidence in its favor. 

(Ibid.) We also provide some relevant background facts from our Supreme Court’s 

decision in Property Reserve, Inc. v. Superior Court (2016) 1 Cal.5th 151 (Property 

Reserve).

“In an effort to improve the reliability of the water supply system in California as 

well as to address environmental and ecological concerns, [DWR] undertook to 

investigate the feasibility of constructing a new tunnel or canal in the Sacramento-San 
4

Joaquin Delta as a means of delivering fresh water from Northern California to Central 

and Southern California. As part of the preliminary steps in going forward with the 

project, [DWR] sought to conduct environmental and geological studies and testing on 

more than 150 privately owned parcels of land that the state, in the future, might seek to 

acquire for the project through negotiation or eminent domain.” (Property Reserve,

supra, 1 Cal.5th at pp. 165-166.) “The proposed new [water conveyance] facilities would 

become part of the Bay Delta Conservation Plan and are intended to improve the 

reliability of the water supply statewide as well as to restore the Delta ecosystem and 

native fish populations.” (Id. at p. 168.)

“Because the alternative potential locations for the new facilities cross or lie 

beneath privately owned lands, [DWR] sought to enter the private properties in question 

to ascertain preliminary environmental and geological information about the properties.” 

(Property Reserve, supra, 1 Cal.5th at p. 168.) “Between 2008 and 2009, [DWR] filed 

more than 150 separate petitions in superior court . . . seeking entry onto properties 

located in five separate counties—San Joaquin, Contra Costa, Solano, Yolo, and 

Sacramento. In June 2009, [DWR] filed a request to coordinate in a single proceeding 

the numerous entry petitions . . . , and in March 2010, the superior court granted the 

request, coordinating the petitions in a single proceeding before the San Joaquin County 

Superior Court.” (Id. at pp. 168-169.) DWR filed a petition seeking to conduct 

“ ‘environmental activities’ ” and “ ‘geological activities’ ” with respect to 35 properties, 

including “drilling deep holes or borings to determine subsoil conditions.” (Id. at p. 169.)

In 2010, DWR published a Mitigated Negative Declaration and Initial Study 

(IS/MND), describing DWR’s plans to conduct further geotechnical information 

gathering.2 The IS/MND stated that DWR’s work “includes overwater and land 

2

 The trial court sustained DWR’s objections to the relevance of the substance of the 

IS/MND, although it permitted the existence of the document itself to be received into the 
5

geotechnical borings, cone penetration tests (CPTs) and small test pits in order to 

investigate soils in the Sacramento-San Joaquin Delta between 2010 and 2012.” It 

asserted the activities “would provide soils data and groundwater conditions,” that the 

project “requires Delta soils and groundwater information,” and that the project requires 

drilling boreholes and performing CPTs to measure “location of the groundwater table” 

and allow estimation of “groundwater conditions.” The IS/MND also provided, 

“[t]emporary test wells may be installed at some sites to investigate soil permeability and 

to allow sampling of dissolved gases in the groundwater,” “[s]ite investigation activities 

may consist of . . . temporary well installation,” and “[s]elect geotechnical drill holes may 

be completed as groundwater monitoring wells.”

Property Reserve and Entry Order

In 2011, the trial court held a hearing during which DWR employees explained the 

need for and scope of the geological activities. (Property Reserve, supra, 1 Cal.5th at 

p. 171.) After determining optimal drilling sites, DWR would conduct “ ‘cone 

penetrometer testing’ ” on each property, which “involves pushing into the ground a long 

rod that emits signals to determine the subsurface composition of the tested land.” (Ibid.) 

On 28 of the 35 properties, DWR geologists indicated that they would also need to “drill 

additional, larger ‘soil borings’ or ‘drill holes.’ ” (Id. at p. 172.)

The trial court denied DWR’s petition as it related to its proposed geological 

activities, which denial was affirmed by a divided panel of this court but reversed by our 

Supreme Court in July 2016. (Property Reserve, supra, 1 Cal.5th at pp. 173, 213.)

record. The court also sustained in its entirety DWR’s objection to a subsequent 

addendum to the IS/MND. As we later explain, these rulings were not an abuse of 

discretion. But we include some mention of the excluded contents, as do the parties in 

their briefing, as necessary to support our discussion of the material considered by the 

trial court and its subsequent rulings.
6

In June 2017, the trial court authorized DWR to enter certain properties in 

Sacramento County for the purpose of conducting “Geological and Drilling Activities” 

(entry order). The entry order stated that the court “has determined the nature and scope 

of the activities reasonably necessary to accomplish the purposes identified, taking due 

consideration of constitutional and statutory requirements. The court has provided 

suitable limitations to strike the best possible balance between the needs of [DWR] and 

the interests of the property owners.” The court concluded DWR “may conduct the 

studies” as follows: “Geological activities . . . will include one or more of the following: 

borings with auger and/or mud rotary drill, soils sampling using a Standard Penetrometer 

test (SPT) barrel and Shelby tubes, Cone Penetrometer test[] (CPT), and geophysical 

borings and surveys to obtain, study and examine soil and groundwater samples and to 

determine groundwater depth.” In June 2019, the County became aware that DWR

intended to begin conducting geotechnical explorations on certain private properties 

located in the Delta portion of Sacramento County and issued a stop work order.

Addendum

In 2019, DWR published an addendum to the IS/MND, which noted that DWR 

had acquired access to additional properties and anticipated undertaking 19 land 

explorations, including boreholes and CPTs, of locations analyzed in the IS/MND. The 

addendum recognized the activities described in the IS/MND “included overwater and 

land geotechnical borings, cone penetration tests (CPT[s]), temporary test wells (i.e. 

piezometers), and small test pits to investigate soils in the Sacramento-San Joaquin 

Delta.” The addendum recognized: “This testing is necessary to gather additional 

geotechnical data in the relevant areas for evaluation of the feasibility of water 

conveyance facility alternatives[,]” and was written to address geotechnical explorations 

on parcels where access was obtained via the entry order. According to the addendum, 

the work would include seven CPTs and 12 land geotechnical borings.
7

County’s Action for Injunctive Relief

The County filed a complaint for damages and injunctive relief against DWR, 

alleging that DWR violated the County’s well-drilling ordinance by failing to apply for or 

obtain required drilling permits from the County before DWR conducted exploratory 

geotechnical drilling, boring, and related activities. (Sac. County Code, § 6.28.030.)

The trial court denied the County’s request for a temporary restraining order 

pending the outcome of its action and the County’s ex parte application for an order 

barring DWR from drilling until the Court of Appeal authorized it to do so. We denied 

the County’s writ of supersedeas requesting an injunction, stay, or other court order 

barring DWR from conducting its geological borings.3

The trial court later granted DWR’s petition to add the County’s action to the 

pending coordinated eminent domain proceedings in the San Joaquin Superior Court. 

The County of San Joaquin subsequently filed a lawsuit against DWR on similar 

grounds; that action was also added to the coordinated eminent domain proceedings.

Summary Judgment

The County and DWR filed cross-motions for summary judgment. DWR argued 

that its work is authorized by the trial court pursuant to the entry order, which allows for 

soil boring and CPT sites, and that it has complied with the entry order and the 

amendments thereto. It asserted the soil borings and CPT sites are for the sole purpose of 

testing soil conditions, and no water was or will be extracted or injected into any soil 

boring or CPT site. Accordingly, DWR contended its geotechnical explorations 

3

 DWR requests that we take judicial notice of the County’s Petition for Writ of 

Supersedeas with Request for Stay it filed in this court, DWR’s opposition to the 

County’s petition, and this court’s order denying the County’s petition. We grant DWR’s 

request. (Evid. Code, § 452, subd. (d) [judicial notice may be taken of records of any 

court of this state].)
8

conducted pursuant to the entry order did not require it to obtain a County permit because 

they do not constitute a well or monitoring well as those terms are defined in chapter 10.

In support of its motion, DWR submitted a declaration of Allan T. Davis, a DWR 

supervising right of way agent. Davis declared: “The soil borings and CPT sites DWR 

are drilling pursuant to the entry order are for the sole purpose of testing the soil, not the 

ground water. [¶] . . . DWR will not be extracting any water from any soil boring or 

CPT site drilled pursuant to the entry order. [¶] . . . DWR will not be injecting any 

water into any soil boring or CPT site drilled pursuant to the entry order. [¶] . . . [¶] . . . 

The soil borings and CPT sites DWR has already completed in Sacramento County did 

not result in the extraction or injection of water into the underground.” The trial court 

admitted Davis’ declaration, and the County does not challenge its admissibility in this 

appeal.

In opposition to DWR’s motion and in its own motion, the County contended 

statements in the IS/MND and addendum, to the extent those activities are authorized by 

the entry order, conflicted with Davis’ declaration. The County also asserted that the 

Legislature incorporated the drilling standards established by DWR Bulletin No. 74-81, 

Water Well Standards: State of California (an administrative bulletin), by referring to the 

bulletin in section 13801, subdivision (c), which requires local authorities to enact 

ordinances meeting or exceeding the standards set forth in the bulletin. According to the 

County, the Legislature’s incorporation of the bulletin by reference expanded the scope 

of chapter 10 to include “test holes” and “exploration holes,” as those terms are defined 

by the bulletin.4

4

 In support of its opposition, the County submitted a declaration of Christopher Hunley, 

the county employee who issued the stop work order to DWR. DWR objected to the 

declaration, and the trial court sustained the objections as to the portions of the 

declaration relevant in this appeal. The County challenges the court’s ruling as to two 
9

DWR objected to the IS/MND and addendum on the basis that those documents 

are irrelevant. DWR asserted that the entry order is the “operative authorizing 

document,” which allows only geotechnical borings and CPT. DWR relied on the Davis 

declaration, in which Davis confirmed that DWR’s geotechnical activities pursuant to the 

entry order consist only of soil borings and CPT for the purpose of acquiring soil samples 

and stratification data. The trial court sustained DWR’s objections to the statements 

contained in the IS/MND and addendum.

The trial court granted DWR’s motion and denied the County’s. The court 

concluded the entry order governs the actual geological activities on the parcels in 

question; while DWR may choose to do less than is authorized by the entry order, “it 

cannot do more than authorized by the [e]ntry [o]rder regardless of what may be in the 

IS/MND.” The court recognized DWR attested that the drillings authorized by the entry 

order are not for the purpose of extracting water from, or injecting water into, the 

underground or for any of the other purposes listed in section 13710, and “there is no 

evidence to the contrary.” The court concluded the IS/MND raises no triable material 

fact because there is no evidence DWR intended to exceed the provisions of the entry 

order and expressly attested it would not do so.

The judgment confirming the trial court’s ruling was signed on May 6, 2020. 

DWR prepared and served notice of entry of judgment on July 13, 2020. The County 

filed its notice of appeal on May 18, 2020. The County’s civil case information

statement was rejected for failure to attach a copy of the judgment from which it was 

appealing, and the County amended its statement to cure the deficiency. The case was 

fully briefed on December 31, 2020 and argument was held at the parties’ request on 

July 20, 2021.

opinion, post.

DISCUSSION

I

Mootness

DWR first asserts that the County’s appeal is moot and should be dismissed 

because it completed its geotechnical drilling activities on the affected parcels, and the 

County’s complaint alleged only a single cause of action for violation of its well-drilling 

ordinance, seeking temporary or preliminary injunctive relief. “ ‘An appeal should be 

dismissed as moot when the occurrence of events renders it impossible for the appellate 

court to grant appellant any effective relief.’ [Citation.] There are three discretionary 

exceptions to the rules regarding mootness allowing a court to review the merits of an 

issue: ‘(1) when the case presents an issue of broad public interest that is likely to recur 

[citation]; (2) when there may be a recurrence of the controversy between the parties 

[citation]; and (3) when a material question remains for the court’s determination.’ ” 

(Santa Monica Baykeeper v. City of Malibu (2011) 193 Cal.App.4th 1538, 1547-1548.)

The County responds that there will be a recurrence of the controversy between 

the parties. Specifically, the County asserts that DWR is continuing to conduct 

exploratory drilling in Sacramento County related to the project. In support, the County 

filed a request for judicial notice that included a California Environmental Quality Act 

(CEQA) notice of preparation issued January 15, 2020, and a mitigated negative 

declaration adopted July 9, 2020, in which DWR detailed its plans to continue drilling as 

part of the project. We grant the County’s request for judicial notice of these documents. 

(Evid. Code, § 452, subd. (c) [judicial notice may be taken of official acts of the 

executive departments of any state].)5

5

 The County also moves to admit new documentary evidence that it asserts is relevant to 

the issue of mootness. Given the delay in the County’s request as well as the cumulative 

nature of the evidence the County seeks to admit, coupled with the County’s lack of 
11

The County further contends this case presents an issue of broad public interest 

that is likely to recur because the project affects no fewer than five counties, the state 

“will undoubtedly have reason to conduct drilling in the future,” whether for the project 

or for some other State purpose, and the issue of groundwater quality is generally of 

broad public interest.

We agree with the County that the issue presented here is likely to recur both 

between these parties and between DWR and other counties. As DWR’s environmental 

filings make clear, the water conveyance project has not been completed, and DWR has 

not completed its geotechnical explorations. Therefore, the issue of whether DWR must 

obtain county permits before conducting geotechnical explorations is likely to recur, 

either between DWR and the County or between DWR and other counties. Accordingly, 

we exercise our discretion to consider the County’s claims on appeal.

II

Sovereign Immunity

The County next challenges the trial court’s conclusion that DWR was not 

required to obtain county permits before conducting its geotechnical exploration activities 

on the affected parcels. The parties agree, and we agree with the parties, that the 

Legislature waived the state’s immunity with respect to activities conducted within the 

scope of chapter 10.6 (§§ 13755 [“Every person shall comply with this chapter and any 

analysis of its “exceptional circumstances” assertion, the motion to augment the record is 

denied.

6

 Generally, when the State of California engages in sovereign activities, “it is not 

subject to local regulations unless the Constitution says it is or the Legislature has 

consented to such regulation.” (Hall v. City of Taft (1956) 47 Cal.2d 177, 183.) 

“ ‘ “Because the ‘state’s immunity from local regulations is merely an extension of the 

concept of sovereign immunity’ [citation], the consent to waive the immunity must be 

stated in ‘express words’ [citation] in a statute [citation].” ’ ” (Bame v. City of Del Mar

(2001) 86 Cal.App.4th 1346, 1356.) An example of such an express waiver is “a statute 

which provides that every ‘person’ must obtain a permit for coastal development from the 
12

regulation adopted pursuant thereto, in addition to standards adopted by any city or 

county”; 13050, subd. (c) [“ ‘Person’ includes any city, county, district, the state, and the 

United States, to the extent authorized by federal law”].) 

The parties, however, disagree on the scope of that waiver. At the outset, we 

recognize that “[l]aws which tend to limit sovereignty are strictly construed in favor of 

the State.” (Greene v. Franchise Tax Bd. (1972) 27 Cal.App.3d 38, 42; Coso Energy 

Developers v. County of Inyo (2004) 122 Cal.App.4th 1512, 1533.)

The County contends that the Legislature expressly waived DWR’s immunity as 

to activities subject to Bulletin No. 74-81, a DWR administrative bulletin entitled “Water 

Well Standards: State of California,” when it enacted a statute requiring “each county . . .

[to] adopt a water well, cathodic protection well, and monitoring well drilling and 

abandonment ordinance that meets or exceeds the standards contained in Bulletin 

[No.] 74-81.” (§ 13801, subd. (c).) DWR disagrees; it contends the Legislature’s 

reference to Bulletin No. 74-81 does not affect the scope of the waiver of immunity, 

which extends only to those activities expressly defined in chapter 10. The trial court 

agreed with DWR and concluded that the provisions of Bulletin No. 74-81 did not 

expand the scope of the Legislature’s express waiver of DWR’s immunity beyond the 

scope of terms defined by chapter 10.

Accordingly, we analyze section 13801 to determine whether the Legislature 

expressly waived immunity as to activities described by Bulletin No. 74-81 but that are 

not within the scope of activities defined by chapter 10. Because “the issue presented 

involves the interpretation of a statute and the application of that statute to undisputed 

facts, it is subject to this court’s independent or de novo review.” (City of Saratoga v. 

Hinz (2004) 115 Cal.App.4th 1202, 1212.)

city and ‘person’ is defined to include the state government.” (Del Norte Disposal, 

Inc. v. Department of Corrections (1994) 26 Cal.App.4th 1009, 1013.)
13

A. Principles of Statutory Interpretation

Our fundamental task in construing a statute is to ascertain the Legislature’s intent 

so as to effectuate the purpose of the law. (Hassan v. Mercy American River Hospital

(2003) 31 Cal.4th 709, 715.) The first step in the interpretative process is to examine the 

words of the statute, because “statutory language is generally the most reliable indicator 

of legislative intent.” (Ibid.) We give the words of a statute their ordinary and usual 

meaning and construe them in the context of the statute as a whole. (Ibid.) “Courts 

should give meaning to every word of a statute if possible, and should avoid a 

construction making any word surplusage.” (Arnett v. Dal Cielo (1996) 14 Cal.4th 4, 

22.)

“Ordinarily, if the statutory language is clear and unambiguous, there is no need 

for judicial construction. [Citation.] Nonetheless, a court may determine whether the 

literal meaning of a statute comports with its purpose. [Citation.] We need not follow 

the plain meaning of a statute when to do so would ‘frustrate[ ] the manifest purposes of 

the legislation as a whole or [lead] to absurd results.’ ” (California School Employees 

Assn. v. Governing Board (1994) 8 Cal.4th 333, 340.)

When the plain meaning of the statutory language is insufficient to resolve the 

question of interpretation, we proceed to the second step of statutory construction. In this 

step, “we may consider various extrinsic aids to help us ascertain the lawmakers’ intent, 

including legislative history, public policy, settled rules of statutory construction, and an 

examination of the evils to be remedied and the legislative scheme encompassing the 

statute in question.” (McAllister v. California Coastal Com. (2008) 169 Cal.App.4th 912, 

928.) “Both the legislative history of the statute and the wider historical circumstances of 

its enactment may be considered in ascertaining the legislative intent.” (Dyna-Med,

Inc. v. Fair Employment & Housing Com. (1987) 43 Cal.3d 1379, 1387.) “Finally, the 

court may consider the impact of an interpretation on public policy, for ‘[w]here 
14

uncertainty exists consideration should be given to the consequences that will flow from 

a particular interpretation.’ ” (Mejia v. Reed (2003) 31 Cal.4th 657, 663.)

B. Chapter 10

Chapter 10 is limited in scope. Its preamble sets forth its areas of concern: “The 

Legislature finds that the greater portion of the water used in this state is obtained from 

underground sources and that those waters are subject to impairment in quality and 

purity, causing detriment to the health, safety and welfare of the people of the state. The 

Legislature therefore declares that the people of the state have a primary interest in the 

location, construction, maintenance, abandonment, and destruction of water wells, 

cathodic protection wells, groundwater monitoring wells, and geothermal heat exchange 

wells, which activities directly affect the quality and purity of underground waters.” 

(§ 13700, italics added.) The Legislature further found that “[i]mproperly constructed 

and abandoned water wells, cathodic protection wells, groundwater monitoring wells, 

and geothermal heat exchange wells” can both “allow contaminated water on the surface 

to flow down the well casing, thereby contaminating the usable groundwater” and “allow 

unstable or low quality groundwater from one groundwater level to flow along the well 

casing to usable groundwater levels, thereby contaminating the usable groundwater.” 

(§ 13701, subds. (a) & (b), italics added.)

Consistent with these findings, chapter 10 defines “well” and “water well,” 

“cathodic protection well,” “monitoring well,” and “geothermal heat exchange well.” 

(§§ 13710-13713.)7 As used in chapter 10, “ ‘[w]ell’ or ‘water well’ ” is defined in part 

as “any artificial excavation constructed by any method for the purpose of extracting 

7

 The only other term expressly defined by chapter 10 establishes an exemption to the 

reporting requirements of the chapter, referring to “wells constructed for the purpose of 

monitoring groundwater which has adversely affected, or threatens to adversely affect,

crop root zones.” (§ 13712.5.)
15

water from, or injecting water into, the underground” (§ 13710), and “[m]onitoring well” 

is defined as “any artificial excavation by any method for the purpose of monitoring 

fluctuations in groundwater levels, quality of underground waters, or the concentration of 

contaminants in underground waters” (§ 13712).

Chapter 10’s provisions reiterate the narrow scope of the chapter. For example, 

section 13750.5 establishes that any person who “undertake[s] to dig, bore, or drill a 

water well, cathodic protection well, groundwater monitoring well, or geothermal heat 

exchange well, to deepen or reperforate such a well, or to abandon or destroy such a 

well,” must possess a specified contractor’s license. Similarly, section 13751 requires 

“[e]very person who digs, bores, or drills a water well, cathodic protection well, 

groundwater monitoring well, or geothermal heat exchange well, abandons or destroys 

such a well, or deepens or reperforates such a well” to file a report of completion.

C. Bulletins No. 74-81 and 74-90 and County Ordinances

Despite the limited scope of chapter 10, the County contends that the Legislature 

expressly waived DWR’s immunity with respect to activities described in Bulletin 

No. 74-81 when it amended section 13801 to add subdivisions (b) through (e) in 1986. 

(Stats. 1986, ch. 1152, § 4; § 13801 was further amended in 1991 and 2010, but those 

amendments did not materially affect subd. (c).) Bulletin No. 74-81 specifies that its 

reporting and well destruction standards apply to “exploration holes” or “test holes,” 

which are found within the bulletin’s definition of “[t]est [w]ells”: “[w]ells constructed 

for the purpose of obtaining the information needed to design a well prior to its 

construction. Such wells are not to be confused with ‘test holes’ or ‘exploration holes’ 

which are temporary in nature (i.e., uncased excavations whose purpose is the immediate 

determination of existing geologic and hydrologic conditions).”

Pursuant to the requirements in section 13801, subdivision (c), the County adopted 

a well protection ordinance. (Sac. County Code, ch. 6.28.) The ordinance requires, inter 

alia, the state to apply for and receive a permit before digging, boring, drilling, 
16

deepening, modifying, repairing, inactivating, or destroying a well, which is defined to 

include exploratory borings. (Id., ch. 6.28.030, subd. (A), ch.6.28.010, subd. (O).)

In 1991, DWR published Bulletin No. 74-90 as a supplement to Bulletin No. 74-

81. Bulletin No. 74-90 clarifies that the two bulletins together contain the “minimum 

requirements for construction, alteration, maintenance, and destruction of water wells, 

monitoring wells, and cathodic protection wells in California.” It asserts it was 

developed “to respond to [DWR] responsibilities under the Water Code, and to keep pace 

with technical advances during the ten-year period following publication of Bulletin 

[No.] 74-81.” Bulletin No. 74-90 excluded the definition for “test holes” and revised the 

definition of “[e]xploration [h]ole” to not include excavations for the purpose of 

determining existing geologic conditions.

D. Analysis

The County contends the Legislature was aware of the existence of Bulletin 

No. 74-81 when it enacted section 13801, and therefore it intended to expand the waiver 

of DWR’s immunity to include “test holes” and “exploration holes” as those terms are 

defined by and subject to the standards set forth in the bulletin. In support of its 

argument, the County cites without discussion or analysis Deborah M. v. Superior Court 

(2005) 128 Cal.App.4th 1181 (Deborah M.). That case, however, is distinguishable. At 

issue in Deborah M. was whether Family Code section 3041.5, subdivision (a) permitted 

drug testing by means of a hair follicle test. The statute provided: “If substance abuse 

testing is ordered by the court, the testing shall be performed in conformance with 

procedures and standards established by the United States Department of Health and 

Human Services for drug testing of federal employees.” (Deborah M., at p. 1190, 

quoting Fam. Code, § 3041.5, subd. (a).) Because the statute expressly stated that the 

testing shall be performed in accordance with federal procedures and standards, the court 

concluded that the statute incorporated those procedures and standards, and a test would 

only be permissible if it were included in the federal standards or allowed by the federal 
17

government. (Deborah M., at pp. 1190-1192.) The court observed that the Legislature 

was aware of the federal guidelines at the time it enacted the statute, and it did not specify 

the types of tests that could be conducted because the federal guidelines did. (Id. at 

pp. 1192-1193.)

The statute here is generally similar to the one at issue in Deborah M. in that both 

statutes refer to an external set of standards. However, the statutes are materially 

distinguishable in their directive and scope as they relate to the Legislature’s waiver of 

DWR’s immunity. In Deborah M., the Legislature declined to identify allowable drug 

tests and instead incorporated federal standards and procedures as the state law standards 

and procedures. Here, conversely, the Legislature did not incorporate the bulletin’s 

definitions to establish the scope of chapter 10. Rather, chapter 10 expressly provides 

definitions “as used in this chapter,” and there is no suggestion in chapter 10 that 

definitions in the bulletin supersede those in sections 13710 through 13713. (See 

Greene v. Franchise Tax Bd., supra, 27 Cal.App.3d at p. 42 [“Laws which tend to limit 

sovereignty are strictly construed in favor of the State”]; Coso Energy Developers v. 

County of Inyo, supra, 122 Cal.App.4th at p. 1533 [same].)

Additionally, where the statute in Deborah M. incorporated federal standards and 

procedures, here section 13801, subdivision (c) does not suggest that the scope of chapter 

10 is affected in any way by Bulletin No. 74-81. Rather, section 13801, subdivision (c) 

requires local authorities to adopt a “water well, cathodic protection well, and monitoring 

well” ordinance meeting or exceeding the standards set forth in Bulletin No. 74-81. 

Although the local ordinance must meet or exceed the bulletin’s standards, the statute 

does not suggest that the scope of chapter 10--and the Legislature’s waiver of DWR’s 

immunity--is broader than those activities defined by chapter 10.

The County contends that enforcing its ordinance only to the extent that it 

addresses “water wells” and “monitoring wells” as defined in chapter 10 “would be to 

read the Legislature’s mandate for local agencies to enforce the Bulletin [No.] 74-81 
18

standards out of [s]ection 13801,” would nullify that part of the statute, and would 

conflict with the court’s duty to give meaning to all provisions of a statute. We disagree. 

Section 13801, subdivision (c) continues to require local authorities to adopt ordinances 

meeting or exceeding the standards in Bulletin No. 74-81. That is not the issue before us. 

The issue before us is the extent to which the Legislature, by its express words, waived 

DWR’s immunity. We conclude that the Legislature waived DWR’s immunity only with 

respect to the activities defined in sections 13710 to 13713.

Our conclusion is supported by California Groundwater Association v. Semitropic 

Water Storage District (2009) 178 Cal.App.4th 1460 (California Groundwater), which 

concluded that the Legislature did not adopt Bulletin No. 74-81 as state law. (Id. at 

p. 1469.) There, the plaintiff water well drilling association challenged the trial court’s 

conclusion that section 13750.5 does not apply to public entities such as the defendant 

water district. Section 13750.5 requires in part that a person who “undertake[s] to dig, 

bore, or drill a water well, cathodic protection well, groundwater monitoring well, or 

geothermal heat exchange well” must possess a “C-57 Water Well Contractor’s License.” 

The appellate court held that the water district was not exempt from the licensing 

requirement expressly set forth in section 13750.5 despite a C-57 licensing exemption for 

public entities in the Contractors’ State License Law; the court observed that the 

licensing requirement was set forth by section 13750.5 and the Water Code contained no 

exceptions from its requirements. (California Groundwater, at pp. 1465-1466.)

The court in California Groundwater also considered whether section 13801 

“effectively incorporates” into state law the licensing exemptions contained in Bulletin 

No. 74-81. (California Groundwater, supra, 178 Cal.App.4th at pp. 1468-1469.) Section 

13801, subdivision (b) requires the State Water Resources Control Board to “adopt a 

model water well, cathodic protection well, and monitoring well drilling and 

abandonment ordinance implementing the standards for water well construction, 

maintenance, and abandonment contained in [Bulletin No. 74-81].” Bulletin No. 74-81 
19

required that contractors must be licensed in accordance with the provisions of the 

licensing law unless exempted by that act, and the water district contended the 

Legislature incorporated those exemptions into the Water Code. (California 

Groundwater, at pp. 1468-1469.)

The court rejected the water district’s argument, concluding in part that the 

Legislature did not adopt Bulletin No. 74-81 as state law. (California Groundwater,

supra, 178 Cal.App.4th at p. 1469.) The court observed that section 13801, subdivision 

(b) directed the state to adopt a model ordinance, which local authorities were to consider 

before adopting an ordinance that “meets or exceeds” the standards set forth in the 

bulletin (§ 13801, subd. (c)), and therefore “the bulletin standards were intended to 

provide a flexible baseline for local ordinances.” (California Groundwater, at p. 1469.) 

The court expressed doubt that Bulletin No. 74-81 had been incorporated into state law 

because DWR had supplemented its requirements with additional provisions in Bulletin 

No. 74-90. (Ibid.) Had Bulletin No. 74-81 been enacted as statutory law, the court 

observed, DWR “would have lacked legislative authorization to amend the bulletin.” 

(Ibid.)

The County attempts to distinguish California Groundwater on the basis that the 

defendant in that case advocated for the court to accept as law a provision in Bulletin 

No. 74-81 that directly conflicted with the clear licensing requirement in chapter 10, 

which did not mention C-57 licensing exemptions. Here, the County argues, the 

Legislature expressly required that enforcing agencies adopt and enforce the drilling 

standards set forth in Bulletin No. 74-81. But the court in California Groundwater did 

not conclude that Bulletin No. 74-81 was not enacted as state law because the provision 

in the bulletin conflicted with a statutory requirement. Rather, as we have discussed, that

court held Bulletin No. 74-81 was not enacted as state law because section 13801, 

subdivision (b) required only that DWR adopt a model ordinance implementing the 

standards in the bulletin for consideration by local authorities, which the local authority 
20

was required to “meet or exceed.” (California Groundwater, supra, 178 Cal.App.4th at 

p. 1469.) Similarly, here, section 13801, subdivision (c) directs local authorities to adopt 

ordinances meeting or exceeding the standards contained in Bulletin No. 74-81, but does 

not expand the scope of chapter 10.

The County also argues that DWR’s authority to supplement the bulletin does not 

affect whether Bulletin No. 74-81 was enacted as statutory law because Bulletin No. 74-

90 has not been referenced by statute. The County does not explain this argument, but it 

appears to contend that Bulletin No. 74-81 was incorporated into state law by section 

13801 while Bulletin No. 74-90 is without legal effect because it was not. However, the 

County does not assert that DWR is prohibited from amending or supplementing its 

bulletins, and we have no reason to believe it is. Accordingly, we share the doubt voiced 

by the California Groundwater court that Bulletin No. 74-81 was enacted into state law, 

while subsequent authorized amendments and supplements to the bulletin were not.

Based on the foregoing, the trial court correctly concluded that DWR is immune 

from the County’s ordinance.8

III

Summary Judgment and the Trial Court’s Evidentiary Rulings

The County challenges the trial court’s decision to grant DWR’s motion for 

summary judgment, arguing that DWR’s statements in the IS/MND and addendum, to the 

8

 Because we hold the plain language of the statute demonstrates its meaning, we do not 

consider the parties’ arguments regarding the legislative history of chapter 10. 

Additionally, because we review the trial court’s decision de novo, we do not consider 

the County’s arguments regarding the trial court’s reasoning. Finally, because we 

conclude the Legislature’s reference to Bulletin No. 74-81 did not expand the scope of 

the Legislature’s waiver of DWR’s immunity, we conclude the trial court did not abuse 

its discretion by sustaining DWR’s objection to the introduction of the bulletins at 

summary judgment because those documents are not relevant to establish the scope of the 

Legislature’s waiver of immunity.
21

extent those documents describe activities authorized by the entry order, create a triable 

issue of fact as to whether DWR’s geotechnical explorations on the affected parcels 

involved constructing “wells” or “monitoring wells” as those terms are defined in chapter 

10. Because the trial court sustained DWR’s objections to the relevance of these 

documents and excluded their contents from consideration, the County also challenges 

these evidentiary rulings.

A. Standard of Review

On a motion for summary judgment, a defendant must show “that one or more 

elements of the cause of action . . . cannot be established, or that there is a complete 

defense to the cause of action.” (Code Civ. Proc., § 437c, subd. (p)(2).) Summary 

judgment is appropriate only “if all the papers submitted show that there is no triable 

issue as to any material fact and that the moving party is entitled to a judgment as a 

matter of law.” (Id., subd. (c).) A triable issue of material fact exists if the evidence and 

inferences therefrom would allow a reasonable juror to find the underlying fact in favor 

of the party opposing summary judgment. (Aguilar v. Atlantic Richfield Co. (2001) 

25 Cal.4th 826, 850.)

“Because this case comes before us after the trial court granted a motion for 

summary judgment, we take the facts from the record that was before the trial court when 

it ruled on that motion. [Citation.] ‘ “We review the trial court’s decision de novo, 

considering all the evidence set forth in the moving and opposing papers except that to 

which objections were made and sustained.” ’ [Citation.] We liberally construe the 

evidence in support of the party opposing summary judgment and resolve doubts 

concerning the evidence in favor of that party.” (Yanowitz v. L’Oreal USA, Inc, supra, 

36 Cal.4th at p. 1037.)

“In performing an independent review of the granting of summary judgment, we 

conduct the same procedure employed by the trial court. We examine (1) the pleadings 

to determine the elements of the claim, (2) the motion to determine if it establishes facts 
22

justifying judgment in the moving party’s favor, and (3) the opposition—assuming 

movant has met its initial burden—to ‘decide whether the opposing party has 

demonstrated the existence of a triable, material fact issue. [Citation.]’ [Citations.] We 

need not defer to the trial court and are not bound by the reasons in its summary 

judgment ruling; we review the ruling of the trial court, not its rationale.” (Oakland 

Raiders v. National Football League (2005) 131 Cal.App.4th 621, 630.)

Furthermore, our review is governed by a fundamental principle of appellate 

procedure, namely, that “ ‘[a] judgment or order of the lower court is presumed 

correct,’ ” and thus, “ ‘error must be affirmatively shown.’ ” (Denham v. Superior Court

(1970) 2 Cal.3d 557, 564.) Under this principle, plaintiff bears the burden of establishing 

error on appeal, even though defendants had the burden of proving their right to summary 

judgment before the trial court. (Frank and Freedus v. Allstate Ins. Co. (1996) 

45 Cal.App.4th 461, 474.) For this reason, our review is limited to contentions 

adequately raised and supported in plaintiff’s brief. (Christoff v. Union Pacific Railroad 

Co. (2005) 134 Cal.App.4th 118, 125-126.)

We review the trial court’s evidentiary rulings on a summary judgment motion for 

an abuse of discretion. (Serri v. Santa Clara University (2014) 226 Cal.App.4th 830, 

852; DiCola v. White Brothers Performance Products, Inc. (2008) 158 Cal.App.4th 666, 

679.)9

9

 We recognize that in Reid v. Google, Inc. (2010) 50 Cal.4th 512, 535, our Supreme 

Court declined to decide “generally whether a trial court’s rulings on evidentiary 

objections based on papers alone in summary judgment proceedings are reviewed for 

abuse of discretion or reviewed de novo.” (See also Nazir v. United Airlines, Inc. (2009) 

178 Cal.App.4th 243, 255, fn. 4 [observing that the standard of review is unsettled and 

assuming, without deciding, that the abuse of discretion standard applies].) But the 

weight of authority--both before and after Reid--holds that an appellate court applies an 

abuse of discretion standard when reviewing a trial court’s ruling on evidentiary 

objections made in connection with a summary judgment motion. (See Serri v. Santa 

Clara University, supra, 226 Cal.App.4th at p. 852 [“According to the weight of 
23

B. Procedural Background

At summary judgment, DWR objected to the IS/MND and addendum on the bases 

that those documents were not relevant to prove or disprove any issue of fact in the 

County’s action and were misleading. DWR asserted that the entry order was the 

operative authorizing document, that order only authorized it to conduct geotechnical 

borings and CPTs, and DWR confirmed through the Davis declaration that it was 

conducting activities pursuant to the entry order only for the purposes of acquiring soil 

samples and stratification data. Accordingly, DWR asserted that any statements it made 

in the IS/MND and addendum did not create a triable issue of fact as to whether DWR 

was conducting any drilling activities within the scope of chapter 10.

The County responded that the IS/MND is DWR’s official environmental record 

of the project plans and tended to prove what DWR’s drilling work will entail. The 

County contended, as it does on appeal, that the IS/MND and addendum are relevant to 

the extent they describe activities authorized by the entry order, which allows DWR to 

“obtain, study, and examine soil and groundwater samples.” The County further asserts

that the IS/MND and addendum remain relevant despite the Davis declaration because 

that declaration conflicts with DWR’s official CEQA documents and the entry order.

The trial court sustained DWR’s objection to the addendum, and it sustained 

DWR’s objection to the IS/MND as to the substance of that document. In its decision 

granting DWR’s motion for summary judgment, the trial court concluded: “The drillings 

authorized by the Court’s [e]ntry [o]rder in this case are not for the purpose of extracting 

water from, or injecting water into, the underground or for any of the other purposes 

listed in [s]ection[ ] 13710,” recognizing that “DWR has attested so, and there is no 

evidence to the contrary.”

authority, appellate courts ‘review the trial court’s evidentiary rulings on summary 

judgment for abuse of discretion’ ”].)
24

C. Analysis

On appeal, the County only asserts that the environmental documents are relevant, 

not that the trial court abused its discretion by sustaining DWR’s objection. 

“ ‘ “Arguments should be tailored according to the applicable standard of appellate 

review.” [Citation.] Failure to acknowledge the proper scope of review is a concession 

of a lack of merit.’ ” (Ewald v. Nationstar Mortgage, LLC (2017) 13 Cal.App.5th 947, 

948; see Sonic Manufacturing Technologies, Inc. v. AAE Systems, Inc. (2011) 

196 Cal.App.4th 456, 465.)

We conclude the trial court’s decision to sustain DWR’s objections to the IS/MND 

and addendum were not an abuse of the court’s discretion. The court correctly observed 

that the entry order governs the geological activities that may occur on the affected 

parcels, and it correctly recognized that DWR may do less, but not more, than what is 

authorized by the order, regardless of what is in the IS/MND or addendum. The entry 

order authorized DWR to conduct “one or more” of the following activities on the 

affected parcels in Sacramento County: “borings with auger and/or mud rotary drill, soils 

sampling using a Standard Penetrometer test (SPT) barrel and Shelby tubes, Cone 

Penetrometer testing (CPT), and geophysical borings and surveys to obtain, study and 

examine soil and groundwater samples and to determine groundwater depth. The 

geological activities are necessary to identify the suitability of the geological conditions 

of each property being studied for various alternative alignment locations for a Delta 

water conveyance project, including surface canal and underground pipeline 

alternatives.”

Contrary to the County’s contention, the Davis declaration does not contradict the 

IS/MND, addendum, or entry order. Although the entry order authorizes DWR to “obtain 

. . . groundwater samples” that would necessitate construction of a “water well” as 

defined in chapter 10 (§ 13710), as we have recognized, DWR was entitled to do less 

than what is authorized by the order. Additionally, while the County refers to general 
25

DWR objectives and requirements stated in the IS/MND and addendum, the County 

failed to provide any evidence to contradict DWR’s express statement that it did not and 

will not conduct activities within the scope of chapter 10 on the affected parcels. The 

County has not pointed to any evidence suggesting that DWR obtained groundwater 

samples on the affected parcels, or that its CPT borings fall within the definition of a 

“water well” or “monitoring well” in chapter 10. Similarly, while the County points to 

various statements about what might be necessary to complete the project, it points to no 

statements of DWR’s intent with respect to the affected parcels that contradicts Davis’ 

declaration.

The County recognizes that there is no evidence that DWR actually conducted 

activities constituting a “well” or a “monitoring well” under chapter 10, but it argues it 

would be impossible for it to present evidence that DWR was conducting or intended to 

conduct activities on the affected parcels that would require a county permit. DWR, 

however, did present evidence establishing that the contrary is true: that DWR did not 

and would not conduct activities on the affected parcels within the scope of chapter 10. 

Nothing in the IS/MND or addendum casts doubt on the Davis declaration, and the trial 

court properly sustained DWR’s objections to that evidence.

Because there is no triable issue of fact as to whether DWR’s geotechnical 

exploration activities were within the scope of chapter 10, the trial court did not err in 

granting DWR’s motion for summary judgment.

D. Other Evidentiary Rulings

The County challenges other evidentiary rulings made by the trial court, including 

sustaining DWR’s objections to excerpts from comments to the draft and final 

environmental impact report (DEIR and FEIR, respectively) and a comment letter, and 

paragraphs 4 and 12 of Hunley’s declaration. Even if we assume error, the County has 

failed to demonstrate prejudice therefrom.
26

The County challenges the trial court’s ruling sustaining DWR’s objections to the 

DEIR on the basis that the DEIR demonstrates DWR was aware of and considered the 

applicability of local ordinances. Similarly, the County challenges the trial court’s ruling 

regarding a County comment letter, which the County contends demonstrates that DWR 

considered the applicability of local ordinances and that the County had put DWR on 

notice of its position that its ordinance would apply to DWR. Finally, the County 

challenges the court’s ruling regarding the FEIR on the basis that it demonstrates that 

DWR suggested it would apply for a county permit. According to the County, it 

introduced the documents “to show why [the County] did not file an action or intervene 

sooner,” and they are relevant to show that DWR and the County had formal 

communications giving the County “some sense” that DWR would seek a county permit. 

The County recognizes that the documents “were not introduced for the purpose of 

insinuating that DWR had already made a commitment to applying for well permits.”

We conclude these documents are not relevant to the issue presented here: 

whether DWR is required to request a permit from the County. Whether DWR 

considered the applicability of the County’s ordinances before declining to apply for a 

permit is irrelevant.

The County next asserts the trial court improperly excluded paragraphs 4 and 12 

of Hunley’s declaration, in which Hunley described what he saw when issuing the work 

order. The County asserts that these paragraphs of the declaration prove that DWR was 

drilling in Sacramento County and that the drilling came within 10 feet of groundwater, 

which is part of the criteria for applicability of the County well ordinance. (Sac. County 

Code, ch. 6.28.010, subd. (O)(6).) But as we have concluded that DWR is immune from 

the County’s ordinance, whether DWR’s activities fall within the parameters of the 

ordinance is irrelevant. The trial court’s decision to sustain DWR’s objection to 

paragraphs 4 and 12 of Hunley’s declaration did not prejudice the County.
27

The County alleges no improperly excluded evidence that gives rise to a genuine 

dispute of material fact as to whether DWR’s geotechnical activities on the affected 

parcels constituted an activity within the scope of chapter 10. Accordingly, the trial court 

did not err by granting DWR’s motion for summary judgment.

DISPOSITION

The judgment is affirmed. Costs on appeal are awarded to DWR. (Cal. Rules of 

Court, rule 8.278(a).)
