Opinion

MORONY, J.

Statement of the Case

This appeal arises out of challenges to the sufficiency of the Tuolumne County General Plan and to the adequacy of the environmental impact report prepared in connection with adoption of the general plan. “The Planning and Zoning Law (Gov. Code, tit. 7, div. 1, commencing with § 65000) requires[s] . . . that the board of supervisors of each county adopt a general plan for the ‘physical development’ of the county, pursuant to section 65300; that the plan be prepared and adopted according to standards established in section 65300.5 and 65301; and that it include each of nine ‘elements’ enumerated and described in section 65302.” (Camp v. Board of Supervisors (1981) 123 Cal. App.3d 334, 340 [176 Cal.Rptr. 620], fn. omitted.)

The California Environmental Quality Act (CEQA) mandates that prior to adoption of a general plan the county must prepare an environmental impact report (EIR) “to provide public agencies and the public in general with detailed information about the effect which a proposed project is likely to have on the environment; to list ways in which the significant effects of such a project might be minimized; and to indicate alternatives to such a project.” (Pub. Resources Code, § 21061.)

On August 18, 1980, the Tuolumne County Board of Supervisors held a hearing at which time they certified the completion of the EIR (also referred to as the MEIR) for the new county general plan. Also on August 18, 1980, the board approved several changes to the wording of the draft general plan and its action was referred back to the planning commission for recommendation. Thereafter, on August 26, 1980, James Ñuzum, Tuolumne County Planning Director, informed the board that the proposals approved by the board for changes in wording of the draft general plan were consistent with the existing environmental impact report which had been certified and approved by the board on August 18. On that date the board adopted the present Tuolumne County General Plan.

On October 1, 1980, appellant Twain Harte Homeowners Association, Inc. filed the instant action in the Tuolumne County Superior Court, seeking a writ of mandate compelling respondent Tuolumne County (hereinafter County) to rescind its certification of the EIR and to prepare a new EIR in compliance with CEQA. Appellant also sought injunctive relief pending preparation of a new EIR and preventing respondent from approving under the new general plan any projects having a significant impact on the environment. An amended petition was filed on December 30, 1980, amending the allegations concerning the EIR and adding a second cause of action seeking to compel County to set aside the general plan and to prepare and adopt a new one in compliance with Government Code section 65302, and further, seeking to recover attorney fees.

On December 30, 1980, an alternative writ of mandate was issued by the superior court. On March 10, 1981, the hearing on the return of the alternative writ was held, together with the motion for a preliminary injunction.

Following trial and posttrial briefing the trial court on July 30, 1981, entered judgment issuing the writ of mandate commanding the County to reconsider including timberland class 3 on the Arvantis scale in the general plan. The court also retained jurisdiction to consider County’s action taken in light of the writ. The remainder of the writ was denied and the alternative writ was discharged.

Twain Harte Homeowners Association, Inc. appeals from the denial of the remainder of the writ.

Appellant’s Contentions

Appellant contends:

1. That the EIR is legally inadequate as it was not prepared and certified pursuant to the mandate of CEQA in that (a) it does not disclose the criteria for determining water and sewer availability, (b) County’s responses to comments about the draft EIR were inadequate, (c) mitigation measures described in the EIR were not included in the general plan, and (d) alleged environmental impacts of changes made in the draft general plan, after the EIR was certified, were not analyzed prior to the adoption of the general plan.

2. That the general plan is legally inadequate in that its land use, circulation, and housing elements do not substantially comply with the requirements of Government Code section 65302.

Standard of Review

The EIR.

This court in Cleary v. County of Stanislaus (1981) 118 Cal.App.3d 348, 352-353 [173 Cal.Rptr. 390] discussed the standard of review applicable when reviewing the sufficiency of environmental impact reports as follows: “The standard for review of the county’s action, is whether it prejudicially abused its discretion. Such abuse is established if the County has not proceeded in a manner required by law or if the agency’s determination is not supported by substantial evidence. ([Pub. Resources Code,] § 21168.5; People v. County of Kern (1974) 39 Cal.App.3d 830, 840 ...; see No Oil, Inc. v. City of Los Angeles (1974) 13 Cal.3d 68, 74 . . . .)”

As the court stated in Environmental Defense Fund, Inc. v. Coastside County Water Dist. (1972) 27 Cal.App.3d 695, 705 [104 Cal.Rptr. 197]: “The court does not have the duty of passing on the validity of the conclusions expressed in the EIR, but only on the sufficiency of the report as an informative document. ...” This was further amplified in Karlson v. City of Camarillo (1980) 100 Cal.App.3d 789, 804-805 [161 Cal.Rptr. 260] as follows: “In reviewing an EIR a paramount consideration is the right of the public to be informed in such a way that it can intelligently weigh the environmental consequences of any contemplated action and have an appropriate voice in the formulation of any decision. But the following principles must also be considered. The EIR is not an action document. Its purpose is to inform governmental decision makers and to focus the political process upon their action affecting the environment. {City of Rancho Palos Verdes v. City Council, supra, 59 Cal.App.3d 869, 890. ...)... The degree of specificity in an EIR will correspond to the degree of specificity involved in the underlying activity which is described in the EIR. ([Cal. Admin. Code, tit. 14,] § 15147.) ‘An EIR should be prepared with a sufficient degree of analysis to provide decision makers with information which enables them to make a decision which intelligently takes account of environmental consequences. An evaluation . . . need not be exhaustive. . . . Disagreement among experts does not make an EIR inadequate. The courts have looked not for perfection but for adequacy, completeness, and a good faith effort at full disclosure. ’ ([Cal. Admin. Code, tit. 14,] § 15150.) Even where specific guidelines have been urged upon the courts as requiring a narrow and restricted approach by the governmental agency, the courts have followed the general tenor of the guidelines, indicating that they are subject to a construction of reasonableness and the court will not seek to impose unreasonable extremes or to inject itself within the area of discretion as to the choice of action to be taken. (Residents Ad Hoc Stadium Com. v. Board of Trustees [1979] 89 Cal.App.3d [274] 286, 287 .. . .)” (Italics added.)

The General Plan.

Government Code section 65301.5 provides that, “The adoption of the general plan or any part or element thereof or the adoption of any amendment to such plan or any part or element thereof is a legislative act which shall be reviewable pursuant to Section 1085 of the Code of Civil Procedure.” (Added by Stats. 1980, ch. 837, § 2, p. 2617.)

As stated in Karlson v. City of Camarillo, supra, 100 Cal.App.3d 789, 798: “Actions taken by an administrative agency in its legislative capacity are reviewable under Code of Civil Procedure section 1085, the traditional writ of mandate. Judicial review is limited to an examination of the proceedings before the agency to determine whether its action has been arbitrary or capricious, or entirely lacking in evidentiary support, or whether it has failed to follow the procedure and give the notices required by law. (Strumsky v. San Diego County Employees Retirement Assn. [1974] 11 Cal.3d 28, 34, fn. 2 [112 Cal.Rptr. 805, 520 P.2d 29].)”

Consequently, under CEQA, judicial review of a general plan adopted by a board of supervisors is governed by Public Resources Code section 21168.5 which provides that: “In any action or proceeding, other than an action or proceeding under section 21168, to attack, review, set aside, void or annul a determination, finding, or decision of a public agency on the grounds of noncompliance with this division, the inquiry shall extend only to whether there was a prejudicial abuse of discretion. Abuse of discretion is established if the agency has not proceeded in a manner required by law or if the determination or decision is not supported by substantial evidence.”

Our inquiry will thus extend to whether the general plan “substantially complies” with the requirements of the Government Code. (Camp v. Board of Supervisors (1981) 123 Cal.App.3d 334, 348 [176 Cal.Rptr. 620].) “ ‘Substantial compliance, as the phrase is used in the decisions, means actual compliance in respect to the substance essential to every reasonable objective of the statute,’ as distinguished from ‘mere technical imperfections of form.’ [Citations.]” (Ibid.) Since such determination is a matter of law, this court need not give deference to the trial court’s findings. (Id. at p. 362.)

It is clear that in reviewing the determination of the board of supervisors the court may not probe the merits of the general plan. (Selby Realty Co. v. City of San Buenaventura (1973) 10 Cal.3d 110, 118 [109 Cal.Rptr. 799, 514 P.2d 111]; Camp v. Board of Supervisors, supra, 123 Cal.App. 3d at p. 348.)

Discussion

1. TheEIR.

a. Is the EIR legally inadequate in not disclosing the criteria for determining water and sewer availability?

In addressing this issue, a brief discussion of the operation of the “decision system” which is the heart of the Tuolumne County General Plan is appropriate. According to the plan itself, “The General Plan maps indicate the type, intensity and distribution of land usé throughout the unincorporated portion of the County. ...”

The general plan map contains eight major categories of land use designations: “residential,” “commercial,” “residential/agricultural,” “resource,” “open space,” “industrially designated areas,” “park and recreation,” and “public/institutional/school.” According to the general plan: “‘Residential’ and ‘Resource’ land use designations on the General Plan maps are determined through the use of a decision system .... The purpose of the decision system is to base General Plan map use designations on a coherent and clearly-defined set of criteria which are consistent with General Plan policies and are applied in a uniform fashion throughout the County. Two characteristics are automatically recognized on the General Plan maps and do not require the application of the decision system in arriving at a General Plan land use designation. Existing urban uses are shown on the General Plan maps as they presently exist. Likewise, lands which were rezoned under Ordinance 695 are given a General Plan land use designation which is consistent with their zoning classification under Ordinance 695 except in those instances where existing use is more intense. In cases where a property’s existing land use is more intensive than its existing Ordinance 695 zoning, it has received a designation which is compatible with its existing land use. The decision system is therefore applied only to lands zoned under Ordinance 352. These (Ordinance 352) lands receive either the general plan designation indicated by the decision system or one which is compatible with their existing land use, whichever is most intensive.”

According to the plan the decision system operates as follows: “In applying the decision system, the initial determination that is made depends on whether the particular parcel being addressed is located within current public water and/or public sewer service areas. If it is, a number of additional factors are considered and appropriate designations are applied. These factors include the existing zoning classification, average parcel size, relative degree of fire hazard, the rating for commercial timber potential or rangeland potential, whether any septic limitations are known to exist in the area, and contiguity to other urban, large-lot or resource areas.”

Essentially, the decision-making process relies initially upon the availability of public water supplies and sewage disposal. If neither of these facilities is in or proposed, a lot size of from two acres per parcel to thirty-seven acres per parcel will be designated.

Appellant contends that because the operation of the decision system is based upon initial decisions concerning the availability of water and sewer services, the EIR is legally inadequate because it does not disclose criteria for determining water and sewer availability. We disagree.

The EIR extensively analyzes the “availability” of water supplies and sewage disposal. Chapter V of the MEIR documentation deals with the necessary infrastructure facilities (e.g., water supply facilities and sanitary sewage systems) needed for urban land uses. Introducing chapter V is the statement that “ [information identifying present level of service, the currently available capacity to service growth, and facility deficiencies and constraints have been considered in designating land uses on the new General Plan. ” There then follows a detailed analysis of the public water sources from “tiny affiliations of a few individuals to large community service districts.”

The MEIR documentation likewise thoroughly describes existing sanitary sewage systems. The two primary methods of sewage disposal, i.e., (1) individual sewage disposal systems (septic tanks), and (2) the six public sewage systems are described in detail.

The general plan sets forth in section VI County’s commitment to provide adequate public services and facilities (e.g., water and sanitary sewers) to its residents. This commitment is expressed in the plan in the “public services and facilities” chapter by specific policies and suggestions for implementation of the policies.

Appellant argues that the initial determination as to water availability is based upon “will serve” letters issued by water purveyors. Thus appellant contends that these water agencies will dictate land use decisions. Appellant apparently misconceives the nature and purpose of such “will serve” letters in effect at the time of the approval of the EIR and the adoption of the general plan. The testimony at the trial in this action clearly established that such letters are, in effect, a commitment of service. Before such a letter is issued the applicant is required to agree to meet certain conditions, absent which, no “will serve” letters will be issued even though the water purveyor has the willingness, capacity, or capability to serve. Hence, County’s criteria is that water availability is positively required. The County has not in any respect abdicated its planning responsibility. In fact, some “will serve” letters have been rejected by County’s staff for various reasons, e.g., “a proposal was premature and inappropriate,” or certain conditional letters “were inadequate and insufficient.”

It would appear that in attacking the EIR on the basis of “will serve” letters, appellant may be confusing the requirements of an EIR for specific projects with those applicable to an EIR prepared to analyze impacts of adopten of a general plan. The different degree of specificity required for each is recognized in California Administrative Code, title 14, section 15147: “The degree of specificity required in an EIR will correspond to the degree of specificity involved in the underlying activity which is described in the EIR.

“(a) An EIR on a construction project will necessarily be more detailed in the specific effects of the project than will be an EIR on the adoption of a local general plan or comprehensive zoning ordinance because the effects of the construction can be predicted with greater accuracy.

“(b) An EIR on projects such as the adoption or amendment of a comprehensive zoning ordinance or a local general plan should focus on the secondary effects that can be expected to follow from the adoption, but the EIR need not be as detailed as an EIR on the specific construction projects that might follow.”

The EIR was sufficiently specific to inform the public and the governmental decisionmakers that land use determinations were initially predicated upon the determination of water and sewer availability. It may not have been exhaustive but it was an adequate, complete, reasoned analysis, and a good faith effort at full disclosure.

b. Sufficiency of County’s responses to comments.

Appellant contends that certain responses of the County to comments upon the draft EIR are inadequate and do not meet the standards of CEQA and the implementing guidelines. Appellant therefore contends that the environmental impact report is inadequate.

The environmental impact report contains numerous letters and comments upon the draft EIR, received from individuals, organizations, and local and state agencies.

In Cleary v. County of Stanislaus, supra, 118 Cal.App.3d 348, 355-357, this court discussed at length the County’s duty to respond to substantial comments made on the EIR and the type of response which is mandated by CEQA. The court quoted extensively from People v. County of Kern, supra, 39 Cal.App.3d 830 [115 Cal.Rptr. 67]. Because it appears to be a thorough and definitive discussion of this issue, that part of the Cleary decision is adopted here in its entirety: “An EIR is an informational document, the purpose of which is to provide the public and public agencies with detailed information about the effect which a proposed project is likely to have on the environment, to list ways in which significant effects might be minimized and to indicate alternatives to such a project. ([Pub. Resources Code,] § 21061; see No Oil, Inc. v. City of Los Angeles, supra, 13 Cal.3d at p. 86.)

“Section 15146, subdivision (b) [of Cal. Admin. Code, tit. 14] states: ‘(b) The response of the Lead Agency to comments received may take the form of a revision of the Draft EIR or may be an attachment to the Draft EIR. The response shall describe the disposition of significant environmental issues raised (e.g., revisions to the proposed project to mitigate anticipated impacts or objections). In particular the major issues raised when the Lead Agency’s position is at variance with recommendations and objections raised in the comments must be addressed in detail giving reasons why specific comments and suggestions were not accepted, and factors of overriding importance warranting an override of the suggestions. ’ (Italics added.) (See Implementing Guidelines, §§ 15150, 15140, subd. (e), 15146, and 15147.)

“In People v. County of Kern, supra, 39 Cal.App.3d 830, 841-842, this court elaborated upon the requirements of the CEQA that legitimate and significant environmental impacts associated with the proposed development be fully, explicitly and specifically addressed in environmental impact reports. The court stated: ‘This regulation, together with other regulations which touch on the point (see Cal. Admin. Code, tit. 14, §§ 15027, 15085 (a), (d), 15143 (b)-(e)) make it abundantly clear that in preparing the final EIR, the County must describe the disposition of each of the significant environmental issues raised and must particularly set forth in detail the reasons why the particular comments and objections were rejected and why the County considered the development of the project to be of overriding importance. The policy of citizen input which underlies the act (Environmental Defense Fund, Inc. v. Coastside County Water Dist., [supra,] 27 Cal.App.3d 695, 704-705 . . .) supports the requirement that the responsible public officials set forth in detail the reasons why the economic and social value of the project, in their opinion, overcomes the significant environmental objections raised by the public. In Silva v. Lynn (1st Cir. 1973) 482 F.2d 1282, 1285, a case decided under the analogous National Environmental Policy Act (see Friends of Mammoth v. Board of Supervisors [1972] 8 Cal.3d 247, 260-261 . . .; County of Inyo v. Yorty [1973] 32 Cal.App.3d 795, 807 . . .), the court explained the policy thusly: “Finally, and perhaps most substantively, the requirement of a detailed statement helps insure the integrity of the process of decision by precluding stubborn problems or serious criticism from being swept under the rug. A conclusory statement ‘unsupported by empirical or experimental data, scientific authorities, or explanatory information of any kind’ not only fails to crystallize issues [citation] but ‘affords no basis for a comparison of the problems involved with the proposed project and the difficulties involved in the alternatives.’ [Citation.] Moreover, where comments from responsible experts or sister agencies disclose new or conflicting data or opinions that cause concern that the agency may not have fully evaluated the project and its alternatives, these comments may not simply be ignored. There must be good faith, reasoned analysis in response. ” (Italics added.) (See also Environmental Defense Fund, Inc. v. Coastside County Water District, supra, 27 Cal.App.3d 695, 704-705, 708; Portland Cement Association v. Ruckelshaus (1973) 486 F.2d 375, 392-394 . . . .) Only by requiring the County to fully comply with the letter of the law can a subversion of the important public purposes of CEQA be avoided, and only by this process will the public be able to determine the environmental and economic values of their elected and appointed officials, thus allowing for appropriate action come election day should a majority of the voters disagree.’ (See also People v. County of Kern (1976) 62 Cal.App.3d 761,769-774 . . .; Russian Hill Improvement Assn. v. Board of Permit Appeals (1974) 44 Cal.App.3d 158, 160 .. . .)”

The Cleary court held that certain responses of the county to the Air Resources Board and the Department of Food and Agriculture were nonspecific and general, and thus inadequate to answer the specific concerns of those agencies. However, the court did find that the response to the Department of Health, Office of Noise Control was adequate where the letter from the department expressed rather general concerns about the increased noise level which a commercial development would possibly produce, because the element of increased noise was considered in the draft EIR, and because the letter from the department raised no new issues. Therefore, the response made thereto by the County in the final EIR “when considered in conjunction with the draft EIR is sufficient.” {Id., at p. 360.) Moreover, the court held that letters received from individuals which raised no new environmental issue which the draft EIR had not recognized or which was not noted in the comment of the state agencies did not require response. {Id., at p. 360.)

Appellant contends that the County’s responses to specific comments on the draft EIR were inadequate. Appellant categorizes these comments under two general headings: water and resource protection policies.

Water Policies.

It is difficult to discern the main thrust of appellant’s argument in this category because of a commingling of theories advanced as to EIR inadequacy with respect to (1) the lack of criteria to determine water availability, (2) insufficient responses to comments, and (3) the failure to incorporate mitigation measures into the general plan. The first theory already has been discussed at length and the third theory will be discussed subsequently. We will attempt to address the second theory separately although realizing that there necessarily will be some overlapping.

Appellant contends that the responses to three letters concerning the general plan’s proposal to base the decision system for land use determination upon an initial categorization concerning the availability of public water and public sewage, were inadequate. These letters are designated numbers 6, 10 and 15 in the EIR.

Letter number 6 by John Buckley contained the comment that “[e]ven to blatantly allow small lots wherever public water will be provided gives planning power to the water companies, does not take into account the cumulative effect of such development if it would become widespread, and does not adequately explain how septic systems, traffic and public service problems will be met.” No specific response to this comment appears in the response section of the MEIR.

Letter number 10 by Glen F. Carrol stated with regard to the general plan, “it also allows extension of water/sewer lines anywhere without approval of the planning agency. It should be subject to review by said body.” The response appearing in the MEIR to this comment is “no comment necessary.”

The Twain Harte Homeowners Association in letter number 15, suggests as a mitigating measure that the County “[rjequire a permit approved by the Board of Supervisors for [extension] or piping of water and sewer lines in Tuolumne County. ” This mitigation proposal was aimed at alleviating appellant’s concern that “the plan allows extension of water and sewer lines anywhere in the county without the approval of the county planning agency. Once water and sewer lines are in urban development is allowed. This gives no direction to water and séwer districts and utility companies. In effect, the plan by its silence, allows these service entities to determine where growth will and will not occur . . . . ”

This comment and the mitigation measure proposed by appellant Twain Harte appear to encompass the comment of the Carrol letter and at least partially encompass the comments contained in the Buckley letter. Therefore, if the response to this letter is considered adequate, failure of a specific response to the letters numbers 6 and 10, which are merely cumulative, would not cause the EIR to be inadequate. (See Cleary v. County of Stanislaus, supra, 118 Cal.App.3d 348.)

The County’s response to the proposed mitigation measure in the Twain Harte letter is as follows: “County officials and local service agencies should coordinate their planning activities. However, it is probably outside the County’s legal authority to dictate which areas water purveyors may or may not serve. Public utilities, for example, have legal service districts within which they must provide hook-ups regardless of the County’s planning preferences (See ref. 6 page V-5 Public Utility Company, for mandatory service requirements) [referring to MEIR Documentation].” The response to the comment concerning abdication of planning responsibility to service agencies is, “Comment on the policy content of the MDGP: no response is necessary.”

However, the County’s response to a comment by Margaret K. Sylva (letter No. 16) also addresses these issues as follows: “On June 27, 1980, the general plan consultant sent letters to each of the water or sewer agencies whose capacity of hook-up data you (or other people) queried. Appendix I contains copies of these survey letters along with a list of agencies to whom these letters were sent. Agencies who responded to the consultant’s June 27 letter are indicated with a check {•/). [1] Tables V-l and V-2 have been revised to reflect the data provided by these agencies. Copies of these tables appear in Appendix E of this report.”

Such responses are adequate because they disclose that the effect of the operation of the EIR decision system is in accordance with appellant’s observations that land use determinations initially are to be made upon the availability of water and sewage services.

The issue then is primarily the degree of specificity required in a response to comments on the general plan and the EIR. Respondent County has certainly provided more than adequate information regarding water and sewer facilities and services and has disclosed the manner in which it obtained information about the availability of water and sewage facilities and services. Hence, the responses of the County disclosed to the populus the impact of the County’s choice to make an initial determination as to urban or nonurban designation upon the availability of water and sewage facilities. The adequacy of the EIR in respect to the determination of such availability has been previously discussed.

Appellant further contends that the EIR not only fails to respond to comments concerning the water supply of the County, but that it contains a misrepresentation when in response to a query of Glen F. Carrol contained in letter number 10 asking, “Is it true that urban development will be allowed on any private land where water services are available—except Williamson Act and timber preserve?”, respondent answered in pertinent part as follows: “In order to receive a multifamily residential or commercial general plan designation, the parcel must be served by both public water and public sewer systems as well as meeting locational criteria.” Appellant contends that this response is misleading because the general plan discloses that “[n]ew commercial development will be served by public water and public sewer systems. In situations where a public sewer will not exist in the foreseeable future, certain commercial uses may be permitted subject to a Conditional Use Permit and approval of the Tuolumne County Health Officer. Self-contained commercial developments may be permitted outside of existing water districts, P.U.C.’s, mutuals, and service districts upon proof of water availability and completion of an approved water system in lieu of ‘public water.’ ” (Italics added.) Thus, appellant contends that the EIR is incorrect. However, because the comment refers to “urban development” and in fact the exception to the public water requirement occurs in “commercial” designations (even though commercial may be considered a subset of urban) it does not appear that this misrepresentation is in fact a substantial one or that it would mislead the public, particularly in view of the fact that the commercial exception appears in the general plan itself.

Resource Protection Policies.

Appellant contends that responses to comments regarding resource protection were inadequate. Appellant contends specifically as follows:

1. Comment contained in Twain Harte Homeowners Association letter 15, “[t]he plan contains policies and statements to maintain natural resource lands important for industries such as timber, agriculture and mining. . . . However, there is no implementation for these policies and they are inconsistent with implementation in appendix A. [The ‘decision system’.] There is no protection for these industries when densities of 6 units per acre are allowed anyplace in the county where water and sewer are provided. (Appendix A.) This lack of implementation and inconsistency will result in a significant adverse impact on the timber, mining and agricultural industries as well as the recreation industry and the natural environment.”

County responds to this comment as follows: “The MDGP permits urban development to occur in areas that are served by both public water and public sewer systems, except in areas where hazards or limitations are known to occur (ref. 5, p. A-l). See response to comment 11-7 for a discussion of the impact associated with public facility expansion policies. ” The referenced comment to public facility expansion policies is as follows: “The provision of public facilities such as roads and public water systems can play a major role in influencing the timing and location of development. Without these facilities, urban development in most cases cannot occur. Conversely, extension of public facilities into an undeveloped area can create or stimulate pressures for development earlier than would otherwise occur. These demands can undermine and ultimately overwhelm any land use regulations which may have sought to preserve open space or achieve a logical sequence of contiguous development. Consequently, public policies for public facility expansion can be used either to promote urban sprawl or to control urban development and reduce the unnecessary economic, social and environmental costs of sprawl.” Thus, the plan appears to admit that development according to the decision system could have a severe impact upon the agricultural, mining and forest industries. (The County acknowledges in the EIR that rangeland which is subdivided into 5-, 10-, or 20-acre parcels is generally considered to have little or no remaining commercial range value.) Appellant contends that the discussion or response to the criticism of the drastic effect of the plan upon timber, mining and agricultural industries within the county is inadequate.

Although appellant contends that there is no discussion or analysis in the EIR of the number of parcels that would be permitted under the previous general plan and the number and location of those parcels that can now be subdivided under the decision system proposed in the new general plan, the MEIR at appendix F sets forth a breakdown of the number of acres which are allocated in the various land use categories proposed in the general plan. Moreover, appellant points to no statutory requirement that the EIR must contain a comparison between the current zoning or land use allocation and that proposed under the general plan.

On appeal, County’s only contention with regard to the adequacy of its response to comments concerning resource protection is that “no planning responsibilities have been abdicated.” County contends that the designations appearing in the general plan are based on the best information available at the time and subject to alteration as inaccuracies are identified. County also contends that timber and mining are provided for in the general plan at page 111:11 [implementation—conservation and resource preservation]. That section provides in pertinent part that the existing zoning ordinance (695) should be modified to achieve consistency with the general plan, which will require additions to or revisions of the zoning to reflect adequately the intention of the general plan’s open space, agricultural resource, and timber resource map designations and policies. Further reference to agricultural values in that section occurs in paragraph B which states: “Permit agricultural and recreational uses in open-space flood and active fault areas if it can be demonstrated that additional flooding, drainage or hazards will not result.” Discussion of mineral resources occurs at paragraph C as follows: “Designate each area shown as ‘Natural Resources’ on the Geotechnical Interpretive maps as a resource overlay zoning district. Require development proposals in these districts to evaluate the quantity and quality of the potential rock and mineral resource(s). If the resource is determined to be valuable, require the development to be designed in a manner which does not preclude the future utilization of the resource.”

It is apparent that such comments do not fully respond to appellant’s remarks in connection with the impact of the decision system upon the timber, mining and agricultural industries within the County.

2. However, the response to similar concerns expressed in Tina Deatsch’s letter number 11 are sufficient and rectify this inadequacy. The Deatsch letter inquires “What will the significant adverse impacts and cumulative impacts of designating lands for five acre lots be on: [|] (a) land so designated? [f] (b) adjacent land? [if] (c) the private land area of the county as a whole? [if] (d) economically valuable natural resources such as timber, agriculture, minerals, wildlife and recreational open space?” The County’s response is set out in the MEIR as follows:

“The rural residential designation, of which five acre lots are a component, functions as an intermediary or buffer between the large-lot agricultural (range and timberland) areas and the more urban (estate and single-family) residential areas. It affords residents the opportunity to live near agricultural areas in a ‘ranchette’ type of environment, thus serving as an integral component in the spectrum of housing types and densities provided by the MDGP.

“Add the following environmental impact to page 15 of the MEIR after line 30:

“ ‘The rural residential designation permits the subdivision of extensive portions of the county . . . into parcels which have little or greatly diminished resource production capabilities. Rangeland which is subdivided into 5, 10 or 20 acre parcels is generally considered to have little or no remaining commercial range value. Similarly, under the County’s current ordinance, commercial timber harvesting is not permitted on 5 acre parcels.’

“Add the following socio-economic impact to page 17 after line 14:

“‘Development at “rural residential” densities significantly reduces the resource potential of the subdivided land while, at the same time, affords relatively few housing opportunities. For example, if a parcel of 40 acres of land is developed at rural residential (5-acre) densities, it would only house approximately 18 people. [Fn. omitted.] If, on the other hand, the same 40 acre parcel has the services necessary to enable it to be developed at single-family residential densities, it could provide housing for approximately 480 people [fn. omitted] or 2,670 percent more people than at rural residential densities.’

“Also see responses to comments 4-2 and 7-4.”

Response to comment 4-2 essentially recognizes that “smaller minimum parcel sizes generally lead to denser human populations and greater wildlife losses.” The response to comment 7-4 discusses the economic dependency of the County on the timber industry and that that industry is “clearly dependent on the continued preservation and management of the County’s commercial timber resources.” The response continues “When timber resources are lost through development, some of the base sector employment losses in the timber industry can be offset with increased levels of emloyment in the construction industry. In the long run, however, this shift in employment does not counteract the negative impacts associated with losses in the timber industry because of the following: [t] The timber industry is based on a renewable resource and therefore provides continued employment as opposed to the construction industry which provides employment on a project-by-project basis. [1] Historically, the county’s manufacturing sector has remained fairly stable while employment in both the construction and tourism industries have been rather cyclical going through boom and bust periods as a result of changing weather, financial or economic conditions. [Citation.]”

Thus, this response does indicate some of the deleterious effects of designating land for five-acre lots. Appellant contends that the response is insufficient because it overlooks the critical aspects of subdividing lands adjacent to actively producing natural resource industries, i.e., problems associated with the use of agricultural herbicides and pesticides in areas of residential development, problems of conducting mining operations, including blasting and truck traffic near residential housing, and questions of conducting timber operations in a watershed being converted to two- and five-acre parcels. Appellant argues that nowhere does the EIR address these concerns. On the other hand, the EIR does indicate that rural residential densities may serve to act as a buffer zone between such uses. The question here is essentially how specific the EIR is required to be, in the absence of any comment which directs the County to address these relatively specific questions. These questions do not appear to have been raised by any of the comments or suggestions for changes in the EIR or general plan prior to their adoption by the County.

In order to address the above mentioned problems and to alleviate their impacts appellant included in its letter (No. 15), a number of proposed mitigation measures. Appellant contends that the proposals were neither incorporated into the project nor did there appear any explanation as to why such mitigation measures were not appropriate.

The letter recommends as a mitigation measure that the County “[djesignate lands which are valuable for timber, agriculture, and mining as large lot. This designation would have priority over urban use in Appendix A. regardless of whether [water] and sewer is available. ” In response to this comment the County stated, “The benefits of the proposed mitigation measure may be offset by the adverse socio-economic impacts associated with having public water or sewer capacity which cannot be utilized. This is a policy decision which must be made by the Board of Supervisors. ” Appellant contends that the EIR failed to discuss whether the impact of having underutilized sewer or water capacity is in any way a reality.

With regard to the adequacy of the response to this proposed mitigation measure, it appears that the board of supervisors in adopting their decision system made a policy decision between expanded urbanization and protection of resources. Such decision should not be second-guessed by this court, as to do so would be to probe the “merits” of the plan.

The determination of the sufficiency of County’s responses to comments upon the draft EIR turns upon the detail required in such responses. In evaluating the adequacy of an EIR for a proposed airport expansion, the evaluation of environmental effects of the proposed project need not be exhaustive. The sufficiency of the EIR is to be viewed in light of what is reasonably feasible. Courts should look for adequacy and completeness in an EIR, not perfection. (San Francisco Ecology Center v. City and County of San Francisco (1975) 48 Cal.App.3d 584, 594 [122 Cal.Rptr. 100].) “While the decision makers must take account of environmental objections [citations], satisfactory answers to these objections may be provided by reference to the EIR itself [citation]. ” (Ibid.) The court in San Francisco Ecology Center v. City and County of San Francisco, supra, facing a similar issue concluded: “The final EIR must include the responses of the proponent agency to significant environmental points raised in the review and consultation process. (Cal.Admin.Code, tit. 14, § 15146.) Appellants contend that the responses were inadequate; but the final EIR responded to objections relating to noise, air pollution, traffic problems, growth-inducing impact and tax burdens on San Francisco residents. While the responses were not exhaustive, they do evince good faith and reasoned analysis. (See People v. County of Kern, supra, 39 Cal.App.3d at p. 842.) We cannot say that the trial court erred in concluding that the EIR was adequate.” (Id., at p. 596.)

In the instant case it does appear that the County responded fully and adequately to comments in numerous instances and that they addressed in great detail many of the issues raised by appellant. The responses as a whole evince good faith and a reasoned analysis, despite the fact that the responses are not exhaustive or thorough in some specific respects. They adequately serve the disclosure purpose which is central to the EIR process.

Consequently, this court finds that there is substantial evidence with respect to the document as a whole that the numerous comments made were responded to by the County in an adequate manner.

c. Mitigation measures.

Appellant complains of the purportedly unexplained failure to include in the final general plan mitigation measures found to be feasible in the EIR, specifically those set forth at pages D-6, D-ll, D-18, and D-33 of the MEIR.

The mitigation measure proposed at page D-6 reads as follows; “Add the following mitigation measure after line 23 on page 20:

“ ‘Protect wildlife habitats by changing MDGP policy 3 on lines 3-4 to read: “. . . such as the riverside riparian communities along the Stanislaus and Tuolumne rivers and other critical wildlife habitats. ” ’ ”

The mitigation measure proposed at page D-ll reads as follows: “Add the following mitigation measure to page 20 under line 23: [f] ‘Place existing domestic wells in “limestone areas” under a quarterly bacteriological sampling program to assure that the public now residing in those areas is receiving safe and potable water.’ ”

The mitigation measure proposed at page D-33 reads as follows: “Add the following mitigation measure to page 21, line 24 of the MEIR [f] ‘Adopt park standards which establish per capita parkland requirements and specify the types of facilities that county parks should contain.’ ”

The precise language of the above mitigation measures which were contained in the EIR and were proposed to be added to the master draft general plan do not appear, at least in the language utilized in the EIR, in the final general plan.

Public Resources Code section 21002 provides as follows: “The Legislature finds and declares that it is the policy of the state that public agencies should not approve projects as proposed if there are feasible alternatives or feasible mitigation measures available which would substantially lessen the significant environmental effects of such projects, and that the procedures required by this division are intended to assist public agencies in systematically identifying both the significant effects of proposed projects and the feasible alternatives or feasible mitigation measures which will avoid or substantially lessen such significant effects. The Legislature further finds and declares that in the event specific economic, social, or other conditions make infeasible such project alternatives or such mitigation measures, individual projects may be approved in spite of one or more significant effects thereof.” Public Resources Code section 21081 states in pertinent part: “[N]o public agency shall approve or carry out a project for which an environmental impact report has been completed which identifies one or more significant effects thereof unless such public agency makes one, or more, of the following findings:

“(a) Changes or alterations have been required in, or incorporated into, such project which mitigate or avoid the significant environmental effects thereof as identified in the completed environmental report.

“(c) Specific economic, social, or other considerations make infeasible the mitigation measures or project alternatives identified in the environmental impact report.”

The notice of determination filed by the board on September 2, 1980, contains the required finding that, “All mitigation measures recommended in the Final Environmental Impact Report were included in the project as approved.” Moreover, the trial court found that, “Mitigation measures proposed in the final environmental impact report were included in the adopted new general plan.”

Respondent contends, and Planning Director Nuzum testified at trial, that the specific mitigation measures, with the exception of the erroneously omitted timber mitigation measure, were contained in the general plan as specific policy statements.

It is contended by County that those policy statements numbers 3, 4, 5 and 6 located at page IU-2 of the general plan contain the essence of the mitigation measure proposed at page D-6 relating to wildlife habitats.

The only specific reference therein to protection of wildlife habitat appears in policy statement 3 which provides in pertinent part that the County “will act in such ways as to preserve natural resource and wildlife habitat areas . . . .”

With regard to the mitigation measure proposed at page D-ll relating to bacteriological sampling of domestic wells located in limestone areas, it is contended that the mitigation measure was included in policy statement 18 at page IH:6 of the general plan. That policy statement reads in pertinent part that, “prior to development in limestone areas, the County of Tuolumne will require a groundwater investigation and a report to be filed with the county which emphasizes the effects of the development upon the water quality. The County may also require wells to be monitored in these areas to ensure that there is no degradation of the groundwater. ”

Although not specifically requiring quarterly bacteriological sampling as stated in the EIR, it appears that this mitigation measure at least substantially incorporates the proposal, although lacking the “teeth” of the mitigation measure specified in the MEIR.

With regard to the mitigation measure relating to park standards, County contends that such mitigation measure was incorporated in the general plan, however, it fails to cite to a specific section. At trial Planning Director Nuzum testified that although the precise language proposed as a mitigating measure was not incorporated into the general plan, “The General Plan does refer to park standards, and part of the implementation of that General Plan would be an ordinance that did spell out that language.” References to park and recreation facilities appear in the general plan at VI:3 and VI:5 as follows:

“11. Parks and recreation facilities of varying size, function, and location will be provided to serve county residents.

“12. Developers of new residential subdivisions of 100 units or greater will be required to dedicate land and/or pay fees in lieu of dedication for the acquisition and development of recreation facilities which directly serve the needs of the subdivision.” (VI:3.)

“J. Whenever possible, acquire future park sites prior to the urbanization or development of an area in order to conserve park acquisition monies. These sites could be leased for agricultural or other uses until park development is required and programmed.

“K. Prepare a Five-Year Capital Improvement Program (CIP) listing the necessary improvements to the County of Tuolumne’s public services and facilities for which funding will be provided.” (VI:5.)

It appears that nowhere in the plan is there a requirement that the County at some point adopt park standards to establish per capita parkland requirements and specify the types of facilities that county parks should contain.

The trial court found that proposed mitigation measures listed in the EIR at pages D-6, D-ll and D-33 had been incorporated into the general plan. Therefore, it must have concluded that these general policy and implementation guidelines were sufficient to incorporate the more specific mitigation measures proposed.

Neither party has directed the court’s attention to any cases dealing with the question of whether a mitigation measure proposed in the environmental impact report to be incorporated in the general plan must be literally incorporated into the plan or the degree to which general policy statements may be deemed to have incorporated specific mitigation proposals. We hold that literal adoption of such proposed mitigation measures into the general plan is not required. We find that there is substantial evidence with respect to the general plan as a whole supporting respondent’s determination, as well as the trial court’s finding, that all mitigation measures recommended were included in the final project as approved.

d. Whether changes to the general plan adopted by the board of supervisors on August 18 required additional environmental analysis under CEQA.

Appellant contends that significant changes were made in the general plan on August 18, 1980, at the same meeting wherein the board adopted the final EIR and that such significant changes were never formally analyzed under the procedures mandated by CEQA.

California Administrative Code, title 14, section 15067 provides in pertinent part that “Where an EIR or Negative Declaration has been prepared, no additional EIR need be prepared unless: [f] (1) Subsequent changes are proposed in the project which will require important revisions of the EIR, due to the involvement of new significant environmental impacts not considered in a previous EIR on the project. ” (Italics added.)

Thus, it appears that if changes adopted at the August 18 board meeting would involve new significant environmental impacts that had not been considered in the previous EIR on the project, a new EIR or a supplement to the adopted EIR would need to be prepared. By the same token, if the environmental impacts of the proposed changes were not significant or, if the existing EIR adequately addressed the significant impacts likely to occur as a result of adoption of the changes, a new EIR need not be prepared.

Government Code section 65356 sets forth a procedure whereby amendments or modifications in the general plan or any part or element thereof can be considered by the legislative body and provides that any previously unconsidered modification to the proposed plan shall be first referred to the planning commission for a report and recommendation. Public hearings need not be held by the planning commission on the proposed change.

It appears that the board of supervisors complied with this procedure by referring adopted changes in the draft general plan to the planning commission for review.

The changes in the draft general plan which were adopted by the board and referred to the planning commission for analysis at the August 18 meeting and which appellant charges were significant were as follows:

(1) Page 13, paragraph 13, was deleted. (H:4, general plan.) Former paragraph 13 had provided that: “Due to seasonal weather and road conditions, heavy industrial development, with the exception of mines and forest products facilities, will not be permitted northeast of Mono Vista.”

(2) On page 18, line 18, the word “contract” was inserted between “Williamson Act” and “Lands” and the word “unnecessary” was inserted before the word “development” so that the final general plan provision reads as follows: “The economically important forest resources in Tuolumne County such as TPZ and Williamson Act contract Lands will be protected against unnecessary development.” (H1:2, general plan, italics added.)

(3) On page 18, line 21, the board added the word “premature” between the words “against” and “subdivision” so that the provision reads as follows: “Economically important range land in Tuolumne County will be protected against premature subdivision and development.” (111:2, general plan, fh. omitted, italics added.)

(4) On page 20, line 13, the existing general policy number 12 was amended to insert the words “critical-use and high occupancy” between the terms “proposed” and “structures” to read as follows: “Ground shaking associated with a major earthquake along the Foothills Fault Zone will probably affect the entire county. Therefore, the County of Tuolumne will ensure that existing and proposed critical-use and high occupancy structures are designed and built to withstand the maximum credible earthquake (as defined in Policy 10) with reasonable safety and without collapse.” (]H:4, general plan, italics added.)

(5) On page 23, paragraph 23 the underlined sentence was added to the following policy: “Urban or clustered development will be acceptable in moderate fire hazard areas in order to maximize the efficiency and effectiveness of fire protection services in the county. Areas identified as ‘high fire hazard’ on the map will be reviewed by the planning staff to determine the true extent of the potential hazard. If the hazard is found to be less significant or if it can be reduced by making improvements in compliance with a hazard reduction plan, the area may be developed pursuant to applicable general plan policies.” (DI:7, general plan, emphasis added.)

(6) Finally, appellant challenges the insertion on page 44, line 18, of the words “outside of existing water districts, PUC’s, mutuals and community service districts” to the policy relating to commercial development as follows: “New commercial development will be served by public water and public sewer systems. In situations where public sewer will not exist in the foreseeable future, certain commercial uses may be permitted subject to a Conditional Use Permit and approval of the Tuolumne County Health Officer. Self contained commercial developments may be permitted outside of existing water districts, P. U. C. ’s, mutuals and service districts upon proof of water availability and completion of an approved water system in lieu of ‘public water’.” (V:3-4 general plan, italics added.)

Appellant alleges that each of these changes will result in significant environmental impacts and that they therefore must be analyzed under CEQA. Although appellant contends that following the revisions, one could reasonably expect that, pursuant to guidelines for implementation of CEQA, an initial study would be prepared by the planning department to analyze whether a negative declaration or an EIR was appropriate (see Cal. Admin. Code, tit. 14, § 15Ó80), it does not appear that such is a necessary procedure.

In the instant case, an EIR already existed and had been adopted pursuant to the regulations set forth in the Administrative Code and according to the procedures set forth in Public Resources Code section 21100 et seq. Because the EIR already existed, unless there would be a significant effect from the proposed change, which impact had not already been addressed in the EIR, neither a public hearing nor an oppportunity to comment on the changes prior to issuance of a negative declaration or adoption of a supplemental EIR is required. The County could and did, pursuant to California Administrative Code, title 14, section 15067, find that the existing EIR adequately addressed the issues raised in the amendments. This was the testimony of County Planning Director Nuzum at trial.

The trial court found that, “The environmental impacts of changes made in the general plan after the final environmental impact report was certified were analyzed by respondents prior to the final adoption of the new general plan and all of the changes made were covered in the final environmental impact report.”

Testimony of Planning Director Nuzum at trial was essentially that the changes adopted by the board on August 18 were proposals for changes and that the planning staff analyzed the proposals for changes to determine whether they had a significant impact and whether they were covered by the existing EIR. Nuzum testified that where proposed changes were significant and not covered by the EIR they were not adopted.,

For convenience, the individual changes in the general plan will be discussed in the same numerical sequence as previously set forth.

(1) It does not appear that there is any explanation or discussion of the impact of deletion of the provision relating to refusal to permit heavy industrial development northeast of Mono Vista, with certain exceptions. This court cannot determine whether that deletion would have a substantial impact, although it appears that it might have a very substantial impact. There appears to be no discussion of this deletion from the general plan which would enable us to say that there was no substantial impact or that the issue of development north of Mono Vista was adequately covered in the environmental impact report. Hence, it should have been further analyzed in the EIR.

(2) The effect of the insertion of the word “contract” in the “Williamson Act contract Lands” provision was to “clarify the distinction between lands that were in a preserve established under the Williamson Act, but not under a Williamson Act contract from those lands that were both in a preserve and . . . under a contract.” Nuzum stated that the
