This is an appeal by the City of Seattle upon direct review from a partial summary judgment in favor of several Seattle businesses in a class action brought in the Ring County Superior Court by those businesses for damages arising from a power outage which they contend was proximately caused by the negligence of the City and Graneo Construction. The appeal asks this court to interpret a section of the Seattle Municipal Code which states that the Seattle City Light Department "shall not be liable for any loss, injury, or damage resulting from the interruption ... of electric service from any cause . . .". The trial court ruled that the ordinance does not provide the City immunity from liability under the facts of this case.

We agree with the trial court and affirm its judgment.

This case arises out of a power outage in Seattle which occurred from August 31, 1988, to September 3, 1988, when an underground fire damaged or destroyed several major electrical feeder cables. It affected an approximately 38-block area north of downtown Seattle. As a consequence, several businesses, respondents here,1 brought this class action against the City of Seattle (City) and against Graneo Construction, Inc. (Graneo). The suit claimed that the City violated RCW 19.122.030 by failing to fulfill its statutory obligation to locate underground electric utility facilities upon request, and that the City was hable for the damages caused by its failure to meet that statutory obligation. Respondents also claimed that the City was liable *609for negligence in failing to use reasonable care to locate and identify its own underground electric facilities. Further, respondents claimed that the City breached its contractual obligation to supply electricity to them.

Appellant City maintains and operates the electric public utility which serves the City of Seattle and is commonly known as Seattle City Light.

Respondent Graneo Construction, Inc., is a Washington corporation engaged in the construction business. On August 31, 1988, it was driving steel piles into the ground and drove through the center of two electrical conduits in the duct crossing Virginia Street to the Securities Building in downtown Seattle. This resulted in an underground fire that damaged or destroyed several major electrical feeder cables serving properties operated by businesses in the area.

Respondents Employco Personnel Services, Inc., Tempura and Teriyaki, Bergman Luggage Company, Inc., L'Oustau, Inc., Market Place Center, Ltd., and Sound Resources, Inc., are businesses operating in downtown Seattle whose electric service was interrupted by the power outage.

Respondent Clise Agency, Inc. (Clise) owns and manages the Securities Building at Fourth Avenue and Virginia Street in downtown Seattle. The sidewalk on the Virginia Street side of the building was in need of repair and Clise earlier hired Graneo to repair and replace it. When Clise hired Graneo, the repair plan included sinking steel pilings as support for a new walkway. A design plan for the project, by Lance Herlocker & Associates, showed an underground conduit of some type running perpendicular to Virginia Street and across the sidewalk next to the Securities Building, although the conduit was not in the area initially intended, for repair.

On August 12, 1988, Graneo submitted a "locate request" to the 1-number locator service at Seattle City Light requesting the location of underground facilities on *610the south side of Virginia Street alongside the Securities Building. The request stated that Graneo intended to drive steel piles underground.

On August 15, 1988, City Light completed its location service in the requested area and marked "no electrical" in the construction area and on the Underground Locate Report form furnished to Graneo.

On August 22, 1988, Graneo made a second "locate request" to City Light because of expansion of the project site. The second request asked for locate service for the 60 feet east of the previously requested area. It also referred to the prior request submitted by Graneo. A third "locate request" was made on August 23, 1988.

On August 24, 1988, City Light completed its second location work in the requested area. The City's locator crew marked an electrical line for a streetlight running through the sidewalk parallel to the south side of Virginia Street from the alley to Fourth Avenue. No other underground facilities were marked by the locator crew.

On August 26, 1988, City Light completed its third and final location in the requested area. The City Light crew marked "no E" for "no electric" on its Underground Locate Report form.

The map of underground facilities used by City Light's locator crew showed that an underground duct ran from a "manhole" on the north side of Virginia Street across the street from the Securities Building within the area in which Graneo was to drive piles. That duct, however, was not marked by the City Light locator crews.

Since 1980, Seattle's electric rate ordinance has provided that "[t]he [City Light] Department shall not be liable for any loss, injury, or damage resulting from the interruption, restoration, or reduction of electric service from any *611cause . . .".2 Respondents in their lawsuit asked for declaratory relief, seeking a judicial determination that the ordinance did not confer upon the City immunity from liability.

Graneo Construction then filed a third party complaint against the Clise Agency, alleging that Clise was negligent in failing to inform Graneo of the location of underground electric facilities that might be endangered by their sidewalk repair project. In response, Clise filed a counterclaim against Graneo and a cross claim against the City of Seattle, seeking contribution and indemnity from Graneo and the City. The City of Seattle filed a cross claim against the Clise Agency.

The City moved to dismiss the respondents' complaint, pursuant to CR 12(b)(6), for failure to state a claim. For purposes of that motion, the City assumed the truth of all of respondents' allegations. The respondents cross-moved for partial summary judgment against the City, and the Clise Agency joined in that motion.

On May 10, 1990, the Honorable Terrence A. Carroll, King County Superior Court, entered an order denying the City's motion to dismiss and granting respondents' motion for partial summary judgment. The order recites, in part:

> Sections 21.49.110(M & N) (1988)[3] of the Seattle Municipal Code and the provisions of any contracts with the plaintiffs incorporating those sections do not confer immunity *612upon the City from liability for its own negligence, whether ordinary, reckless or gross, nor from liability for its breaches of the statutory, contractual and/or common-law duties alleged in this action. Further, even if the referenced sections of the Seattle Municipal Code and the provisions of any contracts with plaintiffs incorporating those sections are construed to apply to the claims alleged in this action, they would be invalid and unenforceable. The referenced ordinances and contractual provisions do not provide the City with immunity from liability under the facts alleged in plaintiffs' complaint.

The court farther declared that the partial summary judgment constituted a final judgment under CR 54(b), thus permitting an expedited appeal. The City of Seattle timely filed this appeal from the partial summary judgment.

The question presented by this case is whether the Seattle electric rate ordinance, SMC 21.49.110(S), confers upon the City immunity from liability for negligence; and, if so, whether the ordinance is invalid because it contravenes public policy or state statutes.

Appellant makes three arguments. *First,*it argues that Seattle's ordinance provision limiting liability for power interruptions is just and reasonable. *Second,*it argues that the limitation on liability clearly applies to damages from power interruptions which allegedly resulted from the City's negligence. *Third,*it argues that Seattle's limitation on liability is not preempted by any Washington statutes.

Public Utility District No. 1 of Chelan County, in a brief amicus curiae, argued that the Underground Utilities Act (RCW 19.122) does not create an independent cause of action for third parties and that the summary judgment of the trial court should be reversed.

A brief amicus curiae was filed on behalf of seven public utility districts: the Snohomish County Public Utility District No. 1, the Franklin County Public Utility District No. 1, the Mason County Public Utility Districts Nos. 1 and 3, the Benton County Public Utility District No. 1, the Grays Harbor Public Utility District No. 1 and the Okanogan Public Utility District No. 1. Those utility districts con*613tended that an electric utility owes no common law duty to its customers to protect them from harm by excavators; that utilities have authority to adopt clauses exculpating them from liability for negligence; that RCW 19.122 does not create a duty for the benefit of third party electric customers; and that the attack on former SMC 21.49-.110(N) is precluded by the doctrine of laches.

GTE-Northwest Incorporated, USWest Communications, Incorporated and the Washington Independent Telephone Association filed a brief amicus curiae. They conclude that RCW 80.04.440 merely preserves rights that existed at common law and does not create a new cause of action or remedy; that RCW 19.122 does not create a new remedy or cause of action; and that public policy reasons support limitations on liability and damages.

The arguments of amicus curiae are consistent with the arguments advanced by the parties whom they favor.

I

Just and Reasonable

While the City contends that the ordinance is "just and reasonable", respondents argue that it is contrary to public policy. The City asserts that under RCW 80.28.0104 it can enact "just and reasonable" rules and regulations.

The Seattle ordinance, SMC 21.49.110(S), speaks for itself. It is not necessary for us to analyze the concept of "just and reasonable" in its implementation.

*614II

Limitation on Liability

Seattle Municipal Code 21.49.110(S) states that:

> The Department shall not be liable for any loss, injury, or damage resulting from the interruption, restoration, or reduction of electric service from *any cause,*including but not limited to failure of generation and distribution systems, inadequacy of energy supply, implementation of emergency plans, or temporary disconnections for repairs and maintenance or failure to pay for service rendered. During an emergency declared by appropriate civil authority, the Department may curtail electric service.

(Italics ours.)

In determining whether the City can confer immunity upon itself in light of RCW 80.04.440 and RCW 80.28.010(7), we look to the rule that statutes must be read together to determine legislative purpose to achieve a "harmonious total statutory scheme . . . which maintains the integrity of the respective statutes."5

RCW 80.04.440 holds utilities liable "to the persons or corporations affected thereby for all loss, damage or injury" caused by the failure to do an act required by state law or commission of an act prohibited by state law. RCW 80.28-.010(7) provides that "[a]n agreement between the customer and the utility, whether oral or written, shall not waive the protections afforded under this chapter." RCW 80.28 regulates gas, electrical and water companies.

RCW 19.122 imposes upon the City the duty to mark its underground utilities and imposes liability for breach of that duty. The chapter explicitly includes "a state, a city, a county, or any subdivision or instrumentality of a state" as subject to its provision.6 It renders them hable for any damages caused by their failure to locate and mark their underground facilities as required by the statute.7

The City of Seattle is not immune from liability. A municipality has only so much immunity as it derives from *615the sovereign. Sovereign immunity was abolished in this state in 1963 when the Legislature declared that " '[t]he State of Washington, whether acting in its governmental or proprietary capacity, *shall be liable*for damages arising out of its tortious conduct to the same extent as if it were a private person or corporation'."8 The Legislature adopted a policy favoring purchase of hability insurance and enacted statutes authorizing local governments to purchase it. The State may purchase, or contract for the purchase of, property and liability insurance for any municipality upon request of the municipality.9 Additionally, local governments may self-insure.10 This insurance "shall include but not be limited to coverage for claims arising from the tortious or negligent conduct of the local government entity . . . or agents . . .". The Legislature in RCW 35.21.415 declined to grant immunity to cities or towns.11 In viewing the statutory scheme as a whole, the conclusion is reached that the Legislature clearly did not intend that the City of Seattle have immunity from "any loss, injury, or damage resulting from the interruption ... of electric service from any cause",12 as stated in the Seattle ordinance.

A municipality may be held liable for injuries to property belonging to another.13 It is firmly established that in a proper case a city may be held liable on the *616theory of negligence.14 A city may be held liable for either a negligent act of commission or a negligent act of omission.15 A city's negligence need not be the sole cause of an injury, but if its negligence concurs with that of another to produce a wrong, both of the tortfeasors may be held hable.16

Ill

Preemption of SMC 21.49.110

The City contends that it relied on the authority of RCW 35.92.05017 when it enacted SMC 21.49.110. That statute allows the City "to regulate and control the use, distribution, and price [of electricity]." The City asserts that the ordinance adopted in 1980, on its face, insulates it from damages for electrical interruption from any cause.

The City argues that the phrase "from any cause" in the ordinance includes power loss or interruption caused by City Light's own acts of negligence. The phrase "from any cause" is followed by examples of causes the City Council had in mind when it enacted the ordinance.18 However, the City admitted that the ordinance could not be read as *617absolving it from liability for acts of gross negligence, recklessness or intentional misconduct. It does argue, however, that the ordinance grants the City immunity from ordinary negligence.

 The City may exercise only such power as is delegated to it by the Legislature.19 It is a general requisite to the validity of an ordinance that it conform to, and not violate, general statutes.20 In case of conflict, the ordinance is void. Attached to "every ordinance or resolution affecting, or adopted by, a municipality, is the implied condition that the same must yield to the predominant power of the state, when that power has been exercised. . . . [W]here there is conflict between a statute and an ordinance, the latter must give way."21 "[Wjhere the state . . . has . . . asserted its jurisdiction over a given subject-matter, and there is no room for concurrence, the municipal charter or ordinance must give way."22 "[A] municipal corporation[] is limited in its powers to those necessarily or fairly implied in or incident to the powers expressly granted, and also those essential to the declared objects and purposes of the corporation. If there is a doubt as to whether the power is granted, it must be denied."23

 The City may enact an ordinance addressing the same subject matter as a state statute if the city ordinance does not conflict with the general laws of the state and the state law does not show on its face an intent to be *618exclusive.24 The test for determining whether a municipal ordinance conflicts with a state statute was set forth in *Bellingham v.*Schampera.25 In that case, this court stated that "whether the ordinance permits or licenses that which the statute forbids and prohibits, and vice versa . . . [is] Q]udged by [the] test ... [of whether the] ordinance is in conflict if it forbids that which the statute permits".26 Applying this test, the ordinance in this case is in conflict with state statutes. The City argues that the ordinance forbids suits for damages for loss of electrical service occasioned by acts of negligence. State statutes, to the contrary, authorize such suits and permit recovery of damages for negligently caused losses.27

The City argues that the purpose of the ordinance is to provide for setting of reasonable rates, and that the City's ability to do that is affected by the ruling of the Superior Court. The City further argues that if it has to defend itself in lawsuits like this, it raises the specter of higher rates for the average citizen. This is a specious argument which is manifestly without merit.

We affirm the decision of the trial court declaring the ordinance, SMC 21.49.110(S), invalid for the reasons that (1) it contravenes state statutes and invokes sovereign immunity; and (2) it is preempted by state statutes.

Seattle Municipal Code (SMC) 21.49.110(S). This ordinance was originally enacted as ordinance 109218 on July 21, 1980, and subsequently reenacted in 1982, 1984, 1985, 1986 and 1989. The 1986 version was in effect at the time of the power outage on August 31, 1988. Throughout the proceedings and in the trial court's order, the ordinance was cited as SMC 21.49.110(M and N) or SMC 21.49.110(N). Distinctions in the different subsection references are immaterial since the texts of current subsection (S) and former subsection (N) are identical.
