SUMMARY

 

A town and its redevelopment agency began the process established by the Community Redevelopment Law (Health & Saf. Code, 33000 et seq.) to adopt a redevelopment plan, which included the preparation of an environmental impact report (EIR) pursuant to the California Environmental Quality Act (CEQA) (Pub. Resources Code, 21000 et seq.). The town certified the EIR and approved the redevelopment plan, which authorized 72 separate development projects. Interested parties brought two actions against the town: a mandamus action, in which plaintiffs claimed the EIR failed to comply with the requirements of CEQA; and, a validation action, in which they claimed the redevelopment plan did not comply with the Community Redevelopment Law. The trial court determined both the EIR and the redevelopment plan complied with governing law and entered judgments accordingly. (Superior Court of Mono County, Nos. 12308 and 12334, N. Edward Denton, Judge.)

 

The Court of Appeal reversed the judgments, directing the trial court to issue the writ of mandate to plaintiffs in their CEQA action and to enter judgment in favor of plaintiffs in the redevelopment action. The court held that the EIR violated CEQA by failing to analyze the indirect or secondary environmental impacts likely to be caused by each of the 72 proposed projects included in the redevelopment plan. By defining a redevelopment plan and all of its proposed projects as a single project under CEQA, the *512 Legislature implied that as much environmental review as possible should occur at the outset of the redevelopment process, with subsequent review limited to situations where significant changes or new information on the plan's constituent projects becomes available (Pub. Resources Code, 21090, 21166). The town's failure to analyze the impacts caused by each proposed project, to the extent information was known or reasonably could have been known about each project, constituted a failure to proceed in the manner required by CEQA. The court also held that no substantial evidence existed in the record to justify a finding that the project area was characterized by any of the statutory conditions that caused blight, so as to qualify the area as blighted under the Community Redevelopment Law. The evidence did not support findings that the project area was characterized by unsafe or unhealthy buildings, factors that prevented or substantially hindered the economically viable use of buildings or lots, or by adjacent or nearby incompatible uses that prevented economic development (Health & Saf. Code, 33031, subd. (a)(1)-(3)). (Opinion by Nicholson, J., with Blease, Acting P. J., and Sims, J., concurring.)

In this consolidated appeal, we address challenges to a redevelopment plan adopted by the Town of Mammoth Lakes and the environmental analysis performed on that plan. The trial court determined both the environmental analysis and the redevelopment plan complied with governing law. We disagree, and reverse both the trial court's judgment upholding the environmental analysis and the trial court's judgment on the validity of the redevelopment plan. Our decision also nullifies the trial court's denial of motions to tax costs in the two actions below.

 

Facts

 

In March of 1996, defendants Town of Mammoth Lakes and Town of Mammoth Lakes Redevelopment Agency (Agency; collectively, the Town) began the process established by the Community Redevelopment Law (Health & Saf. Code, 33000 et seq.) to adopt a redevelopment plan. Part of this process included the preparation of an environmental impact report (EIR) pursuant to the California Environmental Quality Act (CEQA) (Pub. Resources Code, 21000 et seq.).

 

On June 18, 1997, both the Agency's governing board of directors and the town council certified the EIR. The Agency also approved the proposed redevelopment plan and its accompanying report (the Final Report) and forwarded the documents to the town council. On July 2, 1997, the town council adopted Ordinance No. 97-08 approving the redevelopment plan.

 

The redevelopment plan applied to a project area consisting of three areas of land totaling over 1,100 acres: a main area of about 907 acres; subarea 1 consisting of a 30-acre industrial park; and subarea 2 consisting of the approximately 200-acre airport (collectively, the Project Area). Subareas 1 and 2 were not contiguous to the main area or to each other.

 

The main area contains the Town's traditional downtown commercial area as well as approximately 1,200 units of housing, about half of which are condominiums. It also encompasses a site designated for development of a community college and portions of three partially developed recreational resort areas: Lodestar at Mammoth, Juniper Ridge and North Village. The college site, the resort areas and the airport were the subjects of significant *522 proposed development and corresponding environmental review approved before the redevelopment plan was adopted. Most of that proposed development had not occurred, however, by the time the Town adopted the redevelopment plan.

 

Plaintiffs Friends of Mammoth, Andrea M. Lawrence, Patricia Savage and Pat Eckart (collectively plaintiffs) filed two actions challenging the Town's adoption of the redevelopment plan. The first (case No. C029659 on appeal) was a petition for writ of mandate against the Agency and the Town claiming the redevelopment plan EIR failed to comply with the requirements of CEQA. The second (case No. C031043 on appeal) was a validation action under Code of Civil Procedure section 860 et seq. against the Town, the Agency, and all persons interested in the adoption of the redevelopment plan, claiming the redevelopment plan did not comply with the requirements of the Community Redevelopment Law.

 

By judgment dated May 5, 1998, the trial court denied the CEQA mandate petition and awarded costs to the Town. By judgment dated October 21, 1998, the trial court also determined the redevelopment plan was valid, ordered plaintiffs take nothing by their complaint, and awarded costs to the Town. Plaintiffs filed motions to tax costs in each case, both of which were denied in full by the trial court. Plaintiffs timely appealed each judgment. We consolidated the appeals on plaintiffs' motion. [FN1] We will provide additional facts as required. [FN2] *523

CEQA Appeal (case No. C029659)

I. Standard of Review

 

We review the Town's decision certifying the redevelopment plan EIR to determine "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." (Pub. Resources Code, 21168.5; see also Western States Petroleum Assn. v. Superior Court (1995) 9 Cal.4th 559, 567-568 [38 Cal.Rptr.2d 139, 888 P.2d 1268].)

 

"On appeal, our task is the same as the trial court's, 'that is, to review the agency's actions to determine whether the agency complied with the procedures required by law.' [Citation.] The trial court's conclusions are not binding on us." (Davidon Homes v. City of San Jose (1997) 54 Cal.App.4th 106, 113-114 [62 Cal.Rptr.2d 612].) Nevertheless, the EIR is presumed adequate, and plaintiffs bear the burden of proving otherwise. (Pub. Resources Code, 21167.3; State of California v. Superior Court (1990) 222 Cal.App.3d 1416, 1419 [272 Cal.Rptr. 472].)

 

II. Adequacy of EIR's Analysis of Proposed Redevelopment Projects

 

Plaintiffs claim the EIR violated CEQA, and particularly Public Resources Code section 21090, by failing to analyze the indirect or secondary environmental impacts likely to be caused by each of the proposed redevelopment projects included in the redevelopment plan. For the reasons which follow, we agree.

 

If a redevelopment agency desires to use its funds to purchase land or to construct public buildings, facilities or other improvements which will assist in eliminating blight, Health and Safety Code section 33445 requires the redevelopment agency to provide for the "acquisition of property and installation or construction of each facility" in the redevelopment plan. (Health & Saf. Code, 33445, subd. (b), italics added.) The redevelopment agency *524 must also list in its Final Report the "specific projects then proposed by the agency" to eliminate blight. (Health & Saf. Code, 33352, subd. (a).)

 

Complying with these requirements, the Town's redevelopment plan "specifically authorized" the Agency "to provide or participate in providing" at least 72 separate and identified public improvements and facilities. [FN3] The projects read like a municipal wish list. They include an overhead gondola; an expanded community library and meeting hall; a town amphitheater; a 300-seat performing arts theater; a school gymnasium; two 2,000-square-foot childcare facilities; a combined fire, police and emergency operations center; an aquatics center, including an 8-lane 25-yard pool; a conference and ice skating arena; a 20,000- square-foot recreation center; airport runway and taxiway extensions to serve commercial jet aircraft; an expanded airport terminal; and over 2,800 parking spaces in new underground and above-ground parking structures and lots.

 

FN3 The redevelopment plan EIR lists 72 development projects, but the redevelopment plan itself lists 73 separate projects and uses. Further, the Final Report lists 81 separate projects. In their briefs, the parties refer to the proposals as 72, and for the sake of consistency, so do we.

 

The projects include constructing approximately 400 new housing units; upgrading all Town utilities; undergrounding all overhead utility lines; developing a central propane distribution system for commercial areas; installing fiber optic cable throughout the Project Area; developing a geothermal heating system for commercial and public uses; upgrading sewer lines; improving storm drains; and installing various road and pedestrian improvements. The projects also include establishing loan programs to assist in rehabilitating older hotels, improving building facades, and recruiting and retaining businesses. They also propose acquiring various parcels of real property to assist in developing commercial and tourist-oriented uses, including the relocation of certain existing gas stations.

 

The redevelopment plan states "changes in circumstances or designs may alter the location of any of the facilities described above, or require other related facilities." The plan is valid for 30 years.

 

In the Final Report, the Agency briefly described each proposed project, explained how each would address blight, and estimated each project's cost. The Agency projected the total cost of the projects would exceed $136.4 million. The Agency also prepared a "conceptual" map depicting where most of the projects would be located. *525

 

The redevelopment plan EIR was prepared as a "program EIR" pursuant to Guidelines section 15168. [FN4] (3)(See fn. 4.), (2b) The redevelopment plan EIR did not analyze direct or indirect environmental impacts potentially caused by each of the 72 development proposals. The EIR states: "Due to the fact that specific characteristics of individual projects which may result from this Plan are unknown at this time, potential environmental impacts are addressed in general terms." The redevelopment plan EIR thus analyzed primarily the cumulative impacts that could foreseeably occur if all of the proposed projects were actually developed. Much of this analysis was contained in the Town's general plan and general plan EIR as well as other previously prepared planning documents and supporting environmental reviews and was incorporated into the redevelopment plan EIR by reference.

 

FN4 "Guidelines" refers to the state CEQA Guidelines, certified and adopted by the Secretary of the California Resources Agency pursuant to Public Resources Code section 21083 and codified at Code of Regulations, title 14, chapter 3 (Cal. Code Regs., tit. 14, 15000-15387.) Although our Supreme Court has not yet decided whether the Guidelines are regulatory mandates or only interpretive aids, it has instructed us to "afford great weight to the Guidelines except when a provision is clearly unauthorized or erroneous under CEQA." (Laurel Heights Improvement Assn. v. Regents of University of California (1988) 47 Cal.3d 376, 391, fn. 2 [253 Cal.Rptr. 426, 764 P.2d 278].)

 

Table 3-2 of the EIR, "Proposed Uses and Actions," lists all of the 72 development projects and their locations, provides a brief description of each project, and explains how each alleviates blight. Exhibit 3-4 of the EIR is the same map noting the location of the proposed projects as that included in the Final Report. The EIR further explains the map does not include "projects which are program oriented or are district-wide ...."

 

The EIR states "[i]ndividual improvement and redevelopment/development projects would occur in incremental phases over time, based largely on economic consideration, infrastructure improvements, market demand and other planning considerations. The phasing and exact details of each development would be evaluated by the Town of Mammoth Lakes Redevelopment Agency on a case-by-case basis. [] ... All [of the 72 development projects] may be subject to additional environmental review on an individual Redevelopment Plan basis, in accordance with the provisions of Section 15168 of CEQA [Guidelines], as determined necessary by the Town of Mammoth Lakes."

 

At trial, plaintiffs argued the Town violated CEQA by preparing an "ordinary ' program EIR' " for the redevelopment plan. Because Public Resources Code section 21090 restricted subsequent environmental review of development activities performed pursuant to the redevelopment plan but *526 the regulations governing program EIR's did not, plaintiffs argued, the Town was obligated to gather and analyze in the EIR as much information about the 72 development proposals as possible instead of deferring such specific review to later.

 

The trial court rejected plaintiffs' argument. It reasoned the statutory and regulatory scheme equated redevelopment plan EIR's with program EIR's and required the Town to prepare a program EIR. That scheme also did not foreclose future environmental review to the extent plaintiffs feared. The 72 development proposals were just proposals, and CEQA would require the Town to perform additional environmental review should the proposals actually come to fruition and involve new information.

 

Before us, plaintiffs claim the trial court misstated their argument. Because the Town chose to include the 72 development proposals in the redevelopment plan, plaintiffs assert, Public Resources Code section 21090 required the Town to analyze each of the proposals in the EIR (1) to the same extent CEQA requires analysis of impacts normally associated with general plans, and (2) based on all information available to the Town at that time concerning each of the 72 proposals. The Town was not free, they argue, to defer this analysis merely because it prepared a program EIR. Plaintiffs believe under Public Resources Code sections 21090 and 21166 the information available when the redevelopment plan EIR was certified could preclude further environmental review of the 72 development proposals' direct and indirect impacts when the proposed projects are actually developed.

 

To understand the significance of Public Resources Code section 21090 and determine its scope, we first review how CEQA defines a "project" and accommodates projects of various scope and size by providing for different types of EIR's. We then review the level of detail and analysis CEQA requires of EIR's. We will then apply the principles gleaned from this review to determine the level of review CEQA required of the Town's redevelopment plan EIR.

 

To the extent any statutory construction is necessary, we interpret Public Resources Code section 21090 according to the traditional rules of statutory construction. (4) Although "the Legislature intended [CEQA] to be interpreted in such manner as to afford the fullest possible protection to the environment within the reasonable scope of the statutory language" (Friends of Mammoth v. Board of Supervisors (1972) 8 Cal.3d 247, 259 [104 Cal.Rptr. 761, 502 P.2d 1049], disapproved on other grounds by Kowis v. Howard *527 (1992) 3 Cal.4th 888, 896-897 [12 Cal.Rptr.2d 728, 838 P.2d 250]), CEQA itself states "[i]t is the intent of the Legislature that courts, consistent with generally accepted rules of statutory interpretation, shall not interpret [CEQA] or the [Guidelines] in a manner which imposes procedural or substantive requirements beyond those explicitly stated in [CEQA] or in the [Guidelines]." (Pub. Resources Code, 21083.1.)

 

In general, CEQA requires a government agency to prepare an EIR before approving or carrying out any discretionary "project" the agency determines may have a significant effect on the environment. (Pub. Resources Code, 21080, subds. (a), (d).) A "project" is any "activity which may cause either a direct physical change in the environment, or a reasonably foreseeable indirect physical change in the environment, and which is [among other possibilities] [a]n activity directly undertaken by any public agency." (Pub. Resources Code, 21065; see also Guidelines, 15378, subd. (a).) [FN5]

 

FN5 "(1) A direct physical change in the environment is a physical change in the environment which is caused by and immediately related to the project. Examples of direct physical changes in the environment are the dust, noise, and traffic of heavy equipment that would result from construction of a sewage treatment plant and possible odors from operation of the plant.

 

"(2) An indirect physical change in the environment is a physical change in the environment which is not immediately related to the project, but which is caused indirectly by the project. If a direct physical change in the environment in turn causes another change in the environment, then the other change is an indirect physical change in the environment. For example, the construction of a new sewage treatment plant may facilitate population growth in the service area due to the increase in sewage treatment capacity and may lead to an increase in air pollution.

 

"(3) An indirect physical change is to be considered only if that change is a reasonably foreseeable impact which may be caused by the project. A change which is speculative or unlikely to occur is not reasonably foreseeable." (Guidelines, 15064, subd. (d), italics added.)

 

CEQA applies when a public agency proposes to "approve" a project. (Pub. Resources Code, 21080, subd (a); Guidelines, 15352.) An approval is "the decision by a public agency which commits the agency to a definite course of action in regard to a project intended to be carried out by any person." (Guidelines, 15352, subd. (a).)

 

CEQA applies to many types of projects, ranging from the approval of a single use permit for construction of a building to the approval of a local general plan. (Guidelines, 15378, subd. (a)(1).) To accommodate the different types of projects to which it applies, CEQA provides different types of EIRs and accompanying procedures that can be used depending upon the type, specificity, and known detail of the proposed project under review.

 

The project EIR is the most common and detailed type of EIR. It "examines the environmental impacts of a specific development project. This type *528 of EIR should focus primarily on the changes in the environment that would result from the development project. The EIR shall examine all phases of the project including planning, construction, and operation." (Guidelines, 15161.)

 

Once a project EIR has been certified by the lead agency, Public Resources Code section 21166 prohibits additional environmental review on that project unless at least one of three events occurs: "(a) Substantial changes are proposed in the project which will require major revisions of the environmental impact report. [] (b) Substantial changes occur with respect to the circumstances under which the project is being undertaken which will require major revisions in the environmental impact report. [] (c) New information, which was not known and could not have been known at the time the environmental impact report was certified as complete, becomes available." (Pub. Resources Code, 21166; see also Guidelines, 15162, 15163.)

 

In contrast, for projects consisting of a policy, plan, program or ordinance, CEQA encourages agencies to "tier" EIR's and provides a number of ways to do so. Tiering is "the coverage of general matters and environmental effects in an environmental impact report prepared for a policy, plan, program or ordinance followed by narrower or site-specific environmental impact reports which incorporate by reference the discussion in any prior environmental impact report and which concentrate on the environmental effects which (a) are capable of being mitigated, or (b) were not analyzed as significant effects on the environment in the prior environmental impact report." (Pub. Resources Code, 21068.5.)

 

The standard for determining whether to engage in additional CEQA review for subsequent projects under a tiered EIR is more relaxed than the prohibition against additional review imposed by Public Resources Code section 21166 for project EIR's. For a subsequent project that is consistent with the program or plan analyzed in a first tier EIR, CEQA requires a lead agency to prepare an initial study to determine if the later project may cause significant environmental effects not examined in the first tier EIR. If the later project will cause such effects, the lead agency must prepare another EIR. (Pub. Resources Code, 21094, subds. (a), (c).) [FN6]

 

FN6 This second tier EIR need only analyze those significant effects of the later project which were either not mitigated or avoided as a result of the first tier EIR or were not examined at a sufficient level of detail in the first tier EIR to enable those effects to be mitigated or avoided by site-specific revisions, the imposition of conditions, or by other means in connection with the later approval. (Pub. Resources Code, 21094; Guidelines, 15152.)

 

If the subsequent project is not consistent with the program or plan, it is treated as a new project and must be fully analyzed in a projector another *529 tiered EIR if it may have a significant effect on the environment. If the subsequent project is actually the same project reviewed in the first tier EIR, it cannot be subject to further environmental review unless the requirements of Public Resources Code section 21166 are satisfied. (Pub. Resources Code, 21094, subd. (b); Sierra Club v. County of Sonoma (1992) 6 Cal.App.4th 1307, 1319-1321 [8 Cal.Rptr.2d 473].)

 

Now we come to the application of CEQA to a proposed redevelopment plan. Local government agencies establish redevelopment agencies and adopt redevelopment plans to improve, rehabilitate, and redevelop blighted areas. (Health & Saf. Code, 33131.) "As the fundamental document governing a redevelopment agency's activities, a redevelopment plan basically acts as the agency's charter. Adopted by the local legislative body (a city council or county board of supervisors), the plan establishes long-term planning goals as well as implementation policies and procedures for the redevelopment of a designated project area. It also serves as a financing plan by authorizing the agency's use of particular financing tools to implement projects and polices. A redevelopment plan may also establish certain limitations on the authority of a redevelopment agency to conduct activities within a project area. A redevelopment plan is typically a very general document, providing the agency with great flexibility." (Beatty et al., Redevelopment in Cal. (2d ed. 1995) at p. 25.)

 

"By exercising certain of its powers to implement redevelopment, a redevelopment agency may induce private investment in an area. The success of any redevelopment project is dependent upon whether private lenders, developers, owners, and tenants can be persuaded to participate in the process. Thus, a redevelopment agency is unique among public entities since in order to achieve its objective of eliminating blight it must rely upon cooperation with the private sector. Redevelopment is also a process which occurs over a period of years. These realities dictate that a redevelopment plan be written in terms that enhance a redevelopment agency's ability to respond to market conditions, development opportunities and the desires and abilities of owners and tenants. Such a plan then cannot always outline in detail each project that a redevelopment agency will undertake during the life of the plan." (County of Santa Cruz v. City of Watsonville (1985) 177 Cal.App.3d 831, 841 [223 Cal.Rptr. 272].)

 

The redevelopment plan must conform to the local agency's general plan, including the general plan's land use and housing elements. (Health & Saf. Code, 33367, subd. (d)(4).) As stated earlier, a redevelopment plan must name each public facility the redevelopment agency desires to provide or *530 land it seeks to acquire to help alleviate blight. (Health & Saf. Code, 33445.) It must also contain the approximate amount of open space to be provided; limitations on the type, size, height, number, and proposed use of buildings; the approximate number of dwelling units to be provided, and a description of property to be devoted to public purposes and the nature of such purposes. (Health & Saf. Code, 33333, subds. (a)-(d).)

 

The Community Redevelopment Law authorizes redevelopment plans to remain valid for many years. If the redevelopment plan authorizes the redevelopment agency to use tax increment financing, as is the case here, the duration of the redevelopment plan may run as long as, but cannot exceed, 30 years. (Health & Saf. Code, 33333.2, subd. (a)(2).) Indebtedness to be repaid out of tax increments cannot be established beyond 20 years from the plan's adoption and must be repaid within 45 years of the plan's adoption. (Health & Saf. Code, 33333.2, subd. (a)(1), (3).) Also, any eminent domain proceedings to acquire property within the redevelopment project area must be commenced within 12 years of the plan's adoption. (Health & Saf. Code, 33333.2, subd. (a)(4).)

 

Based on the above, a redevelopment plan at first blush would appear to be an ideal candidate for a first tier EIR, with all projects implemented pursuant to the redevelopment plan being subject to their own additional and project-specific EIR's. By adopting Public Resources Code section 21090, however, the Legislature determined a redevelopment plan EIR and all public and private projects implemented pursuant to that plan should be treated as a single project for purposes of CEQA. The statute reads in its entirety: "For all purposes of this division [CEQA], all public and private activities or undertakings pursuant to, or in furtherance of, a redevelopment plan shall be deemed to be a single project. However, further environmental review of any public or private activity or undertaking pursuant to, or in furtherance of, a redevelopment plan shall be conducted if any of the events specified in [Public Resources Code] Section 21166 have occurred."

 

Guidelines section 15180 implements Public Resources Code section 21090 as follows: "(a) All public and private activities or undertakings pursuant to or in furtherance of a redevelopment plan constitute a single project, which shall be deemed approved at the time of adoption of the redevelopment plan by the legislative body.... [] (b) An EIR on a redevelopment plan shall be treated as a program EIR with no subsequent EIRs required for individual components of the redevelopment plan unless a subsequent EIR or a supplement to an EIR would be required by [Guidelines] Section 15162 or 15163." (Italics added.) (Guidelines 15162 and *531 15163 implement Pub. Resources Code, 21166's prohibition of additional environmental review after a project EIR has been certified unless significant change occurs or significant new information develops.)

 

The program EIR referenced in Guideline section 15180 is a type of tiered EIR authorized by the Guidelines but not by the statute. (Al Larson Boat Shop, Inc. v. Board of Harbor Commissioners (1993) 18 Cal.App.4th 729, 740 [22 Cal.Rptr.2d 618].) "A program EIR is an EIR which may be prepared on a series of actions that can be characterized as one large project and are related ... [] [i]n connection with issuance of rules, regulations, plans, or other general criteria to govern the conduct of a continuing program ...." (Guidelines, 15168, subd. (a)(3).)

 

A program EIR is designed to "(1) Provide an occasion for a more exhaustive consideration of effects and alternatives than would be practical in an EIR on an individual action, [] (2) Ensure consideration of cumulative impacts that might be slighted in a case-by-case analysis, [] (3) Avoid duplicative reconsideration of basic policy considerations, [] (4) Allow the lead agency to consider broad policy alternatives and program wide mitigation measures at an early time when the agency has greater flexibility to deal with basic problems or cumulative impacts, [and] [] (5) Allow reduction in paperwork." (Guidelines, 15168, subd. (b).)

 

The Legislature's transformation of a redevelopment plan EIR from what would otherwise be a first tier EIR into a project/program EIR is not without significance. Were it not for Public Resources Code section 21090 and Guidelines section 15180, all activities and subsequent development projects approved pursuant to a redevelopment plan would likely be treated as separate projects and be subject to environmental review for any potentially significant environmental impacts not previously analyzed in the redevelopment plan EIR. (Pub. Resources Code, 21094.)

 

Because of Public Resources Code section 21090 and Guidelines section 15180, further environmental review of any development project implemented pursuant to or in furtherance of a redevelopment plan is prohibited unless significant changes occur in the project or the circumstances surrounding the project, or if significant new information which was not known and could not have been known when the redevelopment plan EIR was certified becomes available. (See Long Beach Sav. & Loan Assn. v. Long Beach Redevelopment Agency (1986) 188 Cal.App.3d 249, 266 [232 Cal.Rptr. 772] [additional EIR not required where redevelopment project did not cause significant changes to project as analyzed in previous redevelopment EIR].) *532

 

It is this fear that the 72 proposed projects will avoid detailed CEQA review as a result of the operation of Public Resources Code section 21090 that forms the crux of plaintiffs' petition. They claim enough information was known (e.g., each project's proposed use and location), or could have been known, when the EIR was certified to prevent future environmental analysis at least of these aspects of the development proposals when the proposals are actually developed. They thus argue section 21090 required the Town "to gather every bit of information known at the time of [the] Redevelopment Plan adoption about the 72 proposed projects which are included in the Redevelopment Plan [and] to conduct environmental analysis of those Development Proposals to the extent [of] the information then available ...."

 

They claim the analysis was not to be a detailed, site-specific analysis. It was, however, to be governed by the information available at the time of the redevelopment plan's adoption, then "tempered" by focusing on each proposal's secondary effects similar to those discussed in an EIR for a general plan. Plaintiffs further cite specific instances where additional information about a few of the proposed projects was allegedly available to the Town, but the Town did not obtain the data for use in the EIR.

 

The language of Public Resources Code section 21090 does not expressly increase the level of analysis required in a redevelopment plan EIR above that required of other types of program EIR's. However, by defining a redevelopment plan and all of its proposed projects as a single project, the Legislature implied that as much environmental review as possible should occur at the outset of the redevelopment process, with subsequent review limited to situations where significant changes or "new information" on the plan's constituent projects becomes available.

 

The Town and its supporting amici curiae mischaracterize the redevelopment plan EIR as a first tier EIR. As shown above, first tier EIR's are not subject to the ban on subsequent review imposed by Public Resources Code section 21166. Thus, courts have allowed first tier EIR's to defer detailed analysis to subsequent project EIR's. (See Al Larson Boat Shop, Inc. v. Board of Harbor Commissioners, supra, 18 Cal.App.4th at pp. 746-747; Guidelines, 15152, subd. (c).)

 

Here, to the extent specific information is now known about one of the proposed 72 development projects, Public Resources Code section 21090 will prevent a project EIR from analyzing impacts derived from that aspect when the project is subsequently developed. While the redevelopment plan *533 EIR may be a type of tiered EIR (Guidelines, 15152, subd. (h)), it does not enjoy all of the flexibility accorded first tier EIR's.

 

The Town claims Guidelines section 15168, subdivision (c)(1), requires the Town to perform additional environmental review of the development projects for impacts not reviewed in the redevelopment plan EIR. This regulation, part of the Guidelines governing program EIR's, states: "If a later activity would have effects that were not examined in the program EIR, a new initial study would need to be prepared leading to either an EIR or a negative declaration." This regulation is inconsistent with the language and effect of Public Resources Code sections 21090 and 21166, and thus cannot apply to redevelopment plan EIR's.

 

Under Public Resources Code section 21166 and its implementing regulation, Guidelines section 15162, a lead agency is not required to use an initial study to determine the effect of new information or changed circumstances. Also, if an agency determines the new information or changed circumstances do not rise to the level of significance requiring an additional EIR, the agency need not take any further action. (Guidelines, 15162, subd. (b).) Furthermore, if the information was known, or could have been known, when the earlier EIR was certified, a new EIR cannot be prepared even if the information is significant.

 

Guidelines section 15168, subdivision (c)(1), if it applied to a redevelopment plan EIR, would require an agency to prepare an initial study and a negative declaration for an impact that did not trigger additional review under Public Resources Code section 21166. It would also require an agency to prepare an EIR for an impact not previously reviewed but which was ascertained from information previously known, contrary to the requirements governing project EIR's and redevelopment plan EIR's under Public Resources Code section 21166 and Guidelines section 15126.

 

" 'Where a statute empowers an administrative agency to adopt regulations, such regulations "must be consistent, not in conflict with the statute ...." ' " (Ontario Community Foundations, Inc. v. State Bd. of Equalization (1984) 35 Cal.3d 811, 816 [201 Cal.Rptr. 165, 678 P.2d 378].) (2d) The inconsistency between Public Resources Code sections 21090 and 21166, and Guidelines section 15168, subdivision (c)(1), renders the later inapplicable to redevelopment plan EIR's.

 

Designating an EIR as a program EIR also does not by itself decrease the level of analysis otherwise required in the EIR. "All EIR's must cover the same general content. (Guidelines, 15120-15132.) (6a) The level of *534 specificity of an EIR is determined by the nature of the project and the 'rule of reason' [citation], rather than any semantic label accorded to the EIR." (Al Larson Boat Shop, Inc. v. Board of Harbor Commissioners, supra, 18 Cal.App.4th at pp. 741-742, fn. omitted.)

 

In fact, the Guidelines do not specify the level of analysis to be performed in a program EIR. Similar to a first tier EIR, a program EIR is designed for analyzing program-wide effects, broad policy alternatives and mitigation measures, cumulative impacts and basic policy considerations, as opposed to specific projects within the program. (Guidelines, 15168, subd. (b)). However, the Guidelines also state a program EIR "will be most helpful in dealing with subsequent activities if it deals with the effects of the program as specifically and comprehensively as possible. With a good and detailed analysis of the program, many subsequent activities could be found to be within the scope of the project described in the program EIR, and no further environmental documents would be required." (Guidelines, 15168, subd. (c)(5), italics added.)

 

In general, "[a]n EIR should be prepared with a sufficient degree of analysis to provide decisionmakers with information which enables them to make a decision which intelligently takes account of environmental consequences. An evaluation of the environmental effects of a proposed project need not be exhaustive, but the sufficiency of an EIR is to be reviewed in the light of what is reasonably feasible.... The courts have looked not for perfection but for adequacy, completeness, and a good faith effort at full disclosure." (Guidelines, 15151.)

 

"No ironclad rules can be imposed regarding the level of detail required .... EIR requirements must be 'sufficiently flexible to encompass vastly different projects with varying levels of specificity.' [Citation.]" (Al Larson Boat Shop, Inc. v. Board of Harbor Commissioners, supra, 18 Cal.App.4th at pp. 745-746.)

 

Accordingly, the Guidelines describe the level of analysis and detail for an EIR as follows: "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 a project such as the adoption or amendment of a comprehensive zoning ordinance or a local general plan *535 should focus on the secondary effects that can be expected to follow from the adoption, or amendment, but the EIR need not be as detailed as an EIR on the specific construction projects that might follow." (Guidelines, 15146.)

 

We cannot determine as a matter of law which of CEQA's various levels of review applies to all redevelopment plan EIR's. A redevelopment plan may be as conceptual as a general plan, as detailed as a conditional use permit, or, as in this case, somewhere in between. Nevertheless, because a redevelopment plan EIR is not a true first tier EIR, and because the Town's redevelopment plan was as detailed as it was, CEQA required the Town's redevelopment plan EIR to contain more analysis of the 72 proposed projects than it did. The Town's failure to analyze the impacts caused by each proposed project, to the extent information was known or reasonably could have been known about each project, constituted a failure to proceed in the manner required by CEQA.

 

The Town argues it should not be required to review each of the proposed development projects because the project being approved was the redevelopment plan, not the individual projects. This argument fails to reckon with the full meaning of the fact that a redevelopment plan, including all "public and private activities or undertakings pursuant to, or in furtherance of," the plan, "shall be deemed to be a single project" under CEQA. (Pub. Resources Code, 21090.) By adopting the redevelopment plan and certifying the EIR, the Town committed itself to the "definite course of action" of implementing the redevelopment plan. (Guidelines, 15352, subd. (a).) It is at least "reasonably foreseeable" the Town will do so by developing at least some of the 72 development projects already approved in the redevelopment plan. This is particularly true since the Town will have to amend the redevelopment plan if it desires to develop any other project not now named in the plan. (Health & Saf. Code, 33445, subd. (b).)

 

The Town claims the 72 development projects had only recommended sites and descriptions, and thereby bore insufficient detail to justify conducting environmental review on any of them individually. In fact, the list, explanation and map of the projects contained in the redevelopment plan, the Final Report, and in the EIR demonstrate many, if not most, of the development projects were defined and formulated with great specificity, including locations, functions, sizes and capacities. The mere fact that changed circumstances could produce changes in the details of the proposals does not render the proposals too vague or indefinite to be reviewed in an EIR such as this. *536

 

In fact, it is the detail with which the Town defines the development projects that compels our decision here. For example, the redevelopment plan calls for construction of a 500-car parking structure at the Juniper Ridge resort; 1,500 parking spaces in structures or lots at the North Village resort; a 250-car parking structure at the Lodestar resort; two 200-car parking structures behind Main Street; and 100-car, 50-car, and 30-car surface parking lots. The conceptual map designates the proposed locations for these different parking lots or structures.

 

By adopting the redevelopment plan, these projects are deemed approved for purposes of CEQA, and no further environmental review may be performed for them unless the requirements of Public Resources Code section 21166 are met. The redevelopment plan EIR does not analyze any significant environmental impacts potentially caused by these projects individually as a result of their proposed use or location. If the Town develops these projects as approved and described in the redevelopment plan, Public Resources Code sections 21090 and 21166 will prohibit the Town from analyzing these projects' impacts arising from their use and location, since that information was known or could have been known when the redevelopment plan EIR was certified.

 

The Town notes the redevelopment plan EIR states the 72 development projects "may be subject to additional environmental review on an individual Redevelopment Plan basis, in accordance with the provisions of [Guidelines] Section 15168 of CEQA ...." (Italics added.) As already demonstrated, CEQA will prohibit additional review of the individual projects unless they or their circumstances change significantly or significant new information which could not have been known when the redevelopment plan EIR was certified comes to light. This statement in the EIR thus offers no guarantee that potential impacts reasonably foreseeable now will be analyzed prior to actual development.

 

At this stage, it may not be possible to conduct a complete analysis of each of these projects because not enough may be known. However, because each project is deemed approved for purposes of CEQA, the significant impacts to the environment likely to be caused by each individual project must be analyzed in the redevelopment plan EIR at least to the same extent each project is detailed in the redevelopment plan and its accompanying Final Report. Otherwise, such analysis may never occur, and nothing in Public Resources Code section 21090 demonstrates the Legislature intended to exempt individual development projects approved in a redevelopment plan and their impacts from environmental analysis under CEQA. *537

 

Amici curiae supporting the Town argue a ruling in plaintiffs' favor would deprive municipalities of the ability to use a program EIR in order to streamline environmental review for redevelopment projects. We disagree. Our ruling merely clarifies what must be included in a redevelopment plan EIR in order for it to obtain the procedural benefits CEQA grants a program EIR without violating the requirement of Public Resources Code section 21090.

 

Amici curiae complain our ruling will make redevelopment planning significantly more complicated and expensive, resulting in fewer redevelopment proposals coming to fruition. These are arguments best addressed to the Legislature. By this decision, we simply enforce the legislative intent expressed in the language of CEQA, and in particular Public Resources Code sections 21090 and 21166, as those statutes apply to the Town's redevelopment plan EIR.

 

Because we reverse the trial court's judgment on the ground discussed above, we do not reach any of the other arguments presented by plaintiffs. Also, our ruling in the CEQA appeal nullifies the trial court's order denying plaintiffs' motion to tax costs. (Monson v. Fischer (1933) 219 Cal. 290, 291 [26 P.2d 6].)

 

Redevelopment Appeal (case No. C031043)

I. Standard of Review

 

The trial court determined the Town adopted the redevelopment plan in the manner required by law and substantial evidence existed in the administrative record supporting the Town's findings of blight. The trial court was required to disregard any error, irregularity, or omission which did not affect the substantial rights of the parties. (Code Civ. Proc., 866.)

 

"[T]he proper standard of review requires us to decide whether substantial evidence supports the judgment of the trial court ...." (County of Riverside v. City of Murrieta (1998) 65 Cal.App.4th 616, 620 [76 Cal.Rptr.2d 606].) Since the trial court affirmed the findings of the Town on the basis of substantial evidence in the administrative record (see In re Redevelopment Plan for Bunker Hill (1964) 61 Cal.2d 21, 39-41, 45-50 [37 Cal.Rptr. 74, 389 P.2d 538]), our task is virtually identical to the trial court's.

 

Defining substantial evidence, one court has well noted: "[I]f the word ' substantial' means anything at all, it clearly implies that such evidence must *538 be of ponderable legal significance. Obviously the word cannot be deemed synonymous with 'any' evidence. It must be reasonable in nature, credible, and of solid value; it must actually be 'substantial' proof of the essentials which the law requires in a particular case." (Estate of Teed (1952) 112 Cal.App.2d 638, 644 [247 P.2d 54], italics added.)

 

Accordingly, a local agency's findings in support of its adopting a redevelopment plan are not conclusive. "The Community Redevelopment Law has established factors to be considered in determining whether an area is blighted, and it is the court's role to ensure those factors are taken into account. In short, the courts are required to be more than rubber stamps for local governments." (Emmington v. Solano County Redevelopment Agency (1987) 195 Cal.App.3d 491, 498 [237 Cal.Rptr. 636].)

 

Unlike CEQA, which required substantial evidence in the administrative record demonstrating only that the EIR provided a reasonable, good faith discussion of the potential impact, the Community Redevelopment Law requires substantial evidence in the administrative record demonstrating the existence of specific characteristics of urbanization and blight. (Health & Saf. Code, 33030, 33031, 33320.1.) In some instances, the statute requires a finding of a nexus, to borrow a term from takings jurisprudence, between a particular characteristic being reviewed and the actual condition being caused. If the specific finding required by the Community Redevelopment Law cannot be made from the evidence in the administrative record, the evidence is not " 'substantial' proof of the essentials which the law requires" and the finding is not supported by substantial evidence. (Estate of Teed, supra, 112 Cal.App.2d at p. 644.)

 

II. Elements of Appeal-Findings Establishing Blighted Area

 

To approve the redevelopment plan, the Town Council had to find, among other things, that the area proposed to be subject to the redevelopment plan, the Project Area, is "a blighted area." (Health & Saf. Code, 33367, subd. (d)(1).) To qualify as a blighted area, the Project Area must satisfy each of the following requirements:

1. The area is "predominantly urbanized." (Health & Saf. Code, 33030, subd. (b)(1).)

 

2. The area is "characterized" by one or more statutorily defined physical conditions that cause blight. (Health & Saf. Code, 33030, subd. (b)(2)(A).) *539

 

3. The area is "characterized" by one or more statutorily defined economic conditions that cause blight. (Health & Saf. Code, 33030, subd. (b)(2)(A).)

 

4. The combination of physical and economic conditions causing blight is "so prevalent and so substantial that it causes a reduction of, or lack of, proper utilization of the area to such an extent that it constitutes a serious physical and economic burden on the community which cannot reasonably be expected to be reversed or alleviated by private enterprise or governmental action, or both, without redevelopment." (Health & Saf. Code, 33030, subd. (b)(1).) [FN7]

 

FN7 Although not pertinent to this case, in lieu of the second and third requirements (being characterized by economic and physical conditions causing blight), the area may instead be characterized by the existence of subdivided lots of irregular form and shape and inadequate size for proper usefulness and development that are in multiple ownership. (Health & Saf. Code, 33030, subd. (b)(2)(B).)

 

An area which meets all of the conditions above may, in addition, be characterized by inadequate public improvements, parking facilities, or utilities. (Health & Saf. Code, 33030, subd. (c).)

 

The trial court found there was substantial evidence in the administrative record on which the Town could find the Project Area was a blighted area. Plaintiffs claim substantial evidence does not exist to support each of the statutory elements required for the Project Area to qualify as a blighted area. We conclude no substantial evidence exists on which the Town and the trial court could find the Project Area is predominantly urbanized and suffers from the statutorily defined physical conditions that cause blight. We explain below why this is so. Since the Town and trial court's findings cannot establish all of the requirements necessary to show the existence of a blighted area, the Town's adoption of the redevelopment plan must be vacated in its entirety. We thus need not review the other arguments raised by plaintiffs against the redevelopment plan. [FN8] *540

 

FN8 Plaintiffs initially fault the Town's use of a structural exterior survey to determine the existence of blight, claiming it resembled a methodology rejected in Gonzales v. City of Santa Ana (1993) 12 Cal.App.4th 1335, 1342-1345 [16 Cal.Rptr.2d 132]. The Gonzales court did not fault the use of a structural exterior survey as a per se improper methodology. Rather, it stated the survey in that case did not by itself result in sufficient evidence to support a finding of blight. (Id. at p. 1345.)

 

The Community Redevelopment Law does not prescribe a particular methodology. At issue here is not whether use of a survey was appropriate, but whether whatever methods the Town used to document the existence of blight resulted in substantial evidence supporting the statutorily required elements of a blighted area.

 

III. Predominantly Urbanized

 

The trial court determined substantial evidence supported the Town's finding that the Project Area was "predominantly urbanized." Plaintiffs claim no substantial evidence supports the Town's finding. We agree with plaintiffs.

 

A predominantly urbanized project area is one where not less than 80 percent of the "land": (1) has been or is "developed for urban uses"; (2) is characterized by the existence of subdivided lots of irregular form and shape and inadequate size for proper usefulness and development that are in multiple ownership; or (3) is an integral part of one or more areas developed for urban uses which are surrounded or substantially surrounded by "parcels" which have been or are "developed for urban uses." (Health & Saf. Code, 33320.1, subd. (b).) A "parcel" is considered "developed" if it is developed in a manner consistent with zoning or otherwise permitted by law. (Health & Saf. Code, 33320.1, subd. (c).)

 

The town council found the Project Area was "predominantly urbanized" based on evidence contained in the Final Report. The Final Report relied upon the building survey to state the Project Area consisted of 1,139 acres, 167.10 of which (or 14.67 percent) were vacant. The Final Report concluded the remaining nonvacant land (85.33 percent) was thus "urbanized." Besides documenting the amount of vacant land, the Final Report states the Project Area "may be considered predominantly urbanized as all properties are an integral part of an area developed for urban uses."

 

The Town also claims the building survey determined approximately 138 acres of the 167 vacant acres existed within "urbanized areas." The Town argues vacant parcels in "urban areas" are "deemed 'urbanized' " under Health and Safety Code section 33320.1, subdivision (b)(3). Based on this theory, the Town believes, and the trial court so held, the Final Report actually underestimated the amount of urbanized land, and the correct figure should be 97 percent, or 1,110 acres of the total 1,139-acre Project Area.

 

At trial, plaintiffs claimed the Final Report's evidence of urbanization consisted only of conclusions without evidentiary support. Plaintiffs also believe the Final Report wrongly inflates the amount of urbanized land in the Project Area. They claim 84 acres of land used as a golf course at the Lodestar resort, 74 acres of undeveloped land at the community college site, and 120 undeveloped acres surrounding the airport were improperly determined to be nonvacant, and thus "urbanized," land. *541

 

The term "urban" is "not fixed, objective, or easily ascertainable...." (County of Riverside v. City of Murrieta, supra, 65 Cal.App.4th at p. 623.) At a minimum, however, the mere fact that property is not vacant or is developed in accordance with its zoning does not by itself render the property "developed for urban uses." Lands that are not vacant may be developed for uses that are not urban uses. (Id. at p. 624.) The Final Report's conclusion that 85 percent of the land is "urbanized" simply because it is not vacant fails to account for this distinction, and thus does not by itself constitute substantial evidence on which the Town could rely to determine the extent of the Project Area's urbanization.

 

Furthermore, since the survey did not determine which nonvacant lands were developed for urban uses and which were not, the Town could not conclude with accuracy which vacant lands were integral parts of land developed for urban uses that were themselves substantially surrounded by parcels developed for urban uses.

 

As to the specific properties challenged by plaintiffs, the entire Lodestar golf course and all of the community college parcel were determined in the building survey not to be vacant and thus urbanized. The Final Report also claimed all of the land at the airport was urbanized. Regarding these properties, the issue, as with all properties claimed by the Town to be urbanized, is whether substantial evidence exists in the administrative record showing that each of these "lands" was either developed for urban uses or was an integral part of an area of land developed for urban uses that was itself substantially surrounded by parcels of land developed for urban uses.

 

A. Lodestar golf course.

 

Analysis of the Lodestar golf course requires reciting additional background information. Lodestar is a proposed 222-acre mixed-use destination resort. The EIR for the project described the project's site as follows: "The site ... is for the most part covered with Sierran Upper Montane Forest. This plant community is characterized by tall conifers that include Jeffrey pine, white fir, and red fir. The vast majority of the forested site is undeveloped with the exception of a few residences and a number of informal trails and dirt roads." (Italics added.)

 

According to the Lodestar at Mammoth Master Plan, adopted by the town council in 1991 and revised in 1992, the Lodestar project would result in the construction of 75 acres of residential units, 10 acres of hotel units, 5 acres of commercial uses, 12 acres of roads, 5 acres of open space, and the approximately 110-acre golf course. The EIR described the golf course as a *542 "mountain style" golf course constructed through the entire site. Numerous ponds and lakes would be developed within the course. Of the lands designated for the golf course and open space, approximately 78 acres would be cleared, leaving 37 acres of natural open space buffer between fairways and adjacent uses. All trees exceeding 36 inches diameter breast height were to be considered for retention within the fairway areas.

 

Other than the construction of some or all of the golf course and one building on the course (apparently a club house with a parking lot), "there has been no implementation" of the Lodestar master plan. Except for the areas used as a golf course, the project site thus presumably retains its forested, undeveloped character.

 

The Town did not include the entire Lodestar project site within the redevelopment Project Area. The Lodestar master plan land use diagram shows the area of the project included in the redevelopment Project Area, a parcel of roughly 80 acres plus two other parcels, was approved to contain eight of the golf course's 18 holes. However, the land use map also shows that same area of the project was approved to contain, in addition to part of the golf course, 30 acres of residential units (a total of 380 units), 10 acres of hotel use (2 hotels containing a total of 500 units) and 5 acres of commercial use (totaling 80,000 square feet).

 

These 45 acres remain undeveloped, but yet the Town classified them as nonvacant and included them as urbanized lands because they were located within the same assessor's parcels as the eight holes of the golf course. Since the golf course was consistent with the parcels' zoning, the Town argues subdivision (c) of Health and Safety Code section 33320.1 allowed the parcels in their entirety to be considered as developed for urban uses.

 

Subdivision (c) of Health and Safety Code section 33320.1 reads: "For purposes of this section, a parcel of property as shown on the official maps of the county assessor is developed if that parcel is developed in a manner which is either consistent with zoning or is otherwise permitted under law." The Town reads subdivision (c) as deeming all of a parcel developed if only a portion of the parcel is developed.

 

The statute's language does not support the Town's interpretation. Subdivision (c) of Health and Safety Code section 33320.1 is concerned with the legality of development, not with the extent of development. It prohibits including parcels fully developed with urban uses in the calculation of developed urban land if that development is illegal. It says nothing of deeming a partially developed parcel to be a fully developed parcel. *543

 

Past amendments to Health and Safety Code section 33320.1 support this reading of subdivision (c) and its application here. In 1983, the Legislature sought to respond to a practice by some redevelopment agencies which had abused the redevelopment process by forming project areas that included significant amounts of unblighted and vacant land. (See Assem. Com. On Revenue and Taxation, Analysis of Assem. Bill No. 1545 (Hannigan) (Apr. 18, 1983) pp. 5, 8 (Assem. Republican Caucus files (1983) Assem. Bill No. 1545).) [FN9] To remedy this problem, the Legislature chose to require the project area to be "predominantly urbanized." It defined that phrase to mean in part that "not less than 80 percent of the privately owned property in the project area has been or is developed for urban uses, ... or is an integral part of an area developed for urban uses." (Stats. 1983, ch. 1324, 1, p. 5352.)

 

FN9 Assembly Bill No. 1545 was ultimately vetoed by the Governor, but not before its provisions amending Health and Safety Code section 33320.1 were adopted by the Legislature as part of Assembly Bill No. 322. That statute became law without the Governor's signature. (See Stats. 1983, ch. 1324, 1, p. 5351.)

 

By 1992, the Legislature had evidence showing some redevelopment agencies continued to form project areas encompassing large tracts of vacant land, despite the statutory amendments adopted in 1983. (See Sen. Local Gov. Com., Analysis of Sen. Bill No. 1711 (Bergeson) (Apr. 13, 1992) p. 6 (Sen. Local Gov. Com. files (1992) Sen. Bill No. 1711).) As a result, the Legislature adopted Senate Bill No. 1711 to tighten further the definition of "predominantly urbanized" in three respects. (Health & Saf. Code, 33320.1; see Stats. 1992, ch. 1356, 4, p. 6777.)

 

First, Senate Bill No. 1711 replaced the word "property" with the word "land." (Health & Saf. Code, 33320.1, subd. (b).) Second, it required 80 percent of all land in the project area, not just privately owned property, to be urbanized. (Ibid.) Third, in order for vacant land to qualify as urbanized because it was an integral part of an area developed for urban uses, Senate Bill No. 1711 required the area developed for urban uses, of which the vacant land was an integral part, to be itself "surrounded or substantially surrounded by parcels which have been or are developed for urban uses." (Health & Saf. Code, 33320.1, subd. (b)(3).)
