Madsen, J.
— This is an action brought under the Land Use Petition Act by a developer challenging the legality of conditions imposed by the City of Camas for approval of a preliminary plat for a residential subdivision. The challenged conditions include a 30 percent “open space” set aside and provision of a secondary limited access road into the proposed development for emergency vehicles. The Clark County Superior Court ruled on constitutional and statutory grounds that both conditions are unlawful. The Court of Appeals affirmed as to the open space requirement, holding that it constitutes an unconstitutional taking, but reversed as to the secondary access road, upholding this condition. We affirm the Court of Appeals, although in part on different grounds. We conclude that the open space set aside condition violates RCW 82.02.020, and thus do not reach arguments respecting the constitutionality of this requirement. We hold that the developer has failed to establish unconstitutionality or other invalidity of the secondary access road condition.
FACTS
In March 1995, the developer, Isla Verde International Holdings, Inc., and Connaught International Holdings, Inc. [746]*746(together Isla Verde), submitted a preliminary plat application for a proposed 32-lot subdivision, Dove Hill, on 13.4 acres located in the City of Camas (City), in Clark County. The Director of Public Works for the City issued a determination of nonsignificance for the project. The plat application was later amended to include 51 lots.
Isla Verde planned to extend an existing road, Sierra Lane, into the new subdivision to provide the only access. Sierra Lane would be “stubbed” at the north edge of the development, with plans that it be extended when property to the north of Dove Hill was developed.
The Camas Planning Commission considered Isla Verde’s application for preliminary plat approval at several meetings. A number of local residents testified that Sierra Lane often becomes impassable in winter conditions, and that residents of a subdivision south of the proposed subdivision have to park their vehicles at the bottom of the hill because the road becomes impassable. Several residents expressed concerns about fire safety issues. The Camas Fire Marshal also spoke about fire protection. He described the steep-sloped nature of the property, and the danger of wildfires in the area.1 He asked for a secondary access road for emergency vehicles, describing access into Dove Hill as a very bad situation.
The Planning Commission considered how the proposed subdivision would satisfy the City’s “open space” ordinance, former Camas Municipal Code (CMC) 18.62.020 (1991) (repealed Mar. 2002),2 which requires that every proposed subdivision in the city must retain 30 percent of its area as [747]*747open space. A June 16, 1995, staff report presented at the June 20, 1995, Planning Commission meeting included findings that, due to its location and configuration, the developer would meet only 37 percent of the total required acreage for open space. The remainder would he satisfied by a “buy down,” i.e., a payment partially in lieu of the set aside, as permitted within the discretion of the Camas City Council by CMC 17.12.090(E) (1991).* *3 The report said that wildlife would be affected by the development, but a notation added that this comment was made with regard to the original 32-lot proposal. The report also included a notation that a concern had arisen about permitting a “buy down” in lieu of a full 30 percent open space set aside. This is evidently a reference to a June 12, 1995, letter from the City Administrator to the Assistant City Engineer/City Planner recommending that the Planning Commission approve a plat design with a full 30 percent open space set aside. The open space would largely consist of steep wooded slopes. The City Administrator explained that the City Council’s recent decisions on proposed subdivisions had [748]*748generally preferred the open space set aside rather than the optional “buy down.” He said that a 30 percent set aside would add about four acres to the City’s open space network, would be consistent with the objectives of the open space network, and would be consistent with past council decisions.
The Planning Commission approved the application, subject to a number of conditions, including construction of a secondary temporary access road from the end of NW Sierra Lane to an acceptable point to the east. The recommended conditions also contemplated that a homeowner’s association would be required and that it would be responsible for maintenance of the open space areas.
On June 26, 1995, Isla Verde’s application came before the Camas City Council for a final decision. The Council permitted local residents to comment on the application, and, with regard to a secondary access road, the same concerns regarding fire protection and access that were raised in the Planning Commission’s meetings were voiced before the Council. The Fire Marshal again expressed concerns about fire protection and access to the proposed development. He also pointed out that the Uniform Fire Code required more than one access road for fire fighting equipment when a determination was made by the fire chief “that access by a single road may be impaired by vehicle congestion, condition of terrain, climatic conditions or other factors that could limit access.” Clerk’s Papers (CP) at 107. The neighbor to the east of the proposed subdivision stated that she would not grant an easement for a secondary access road over her property.
With regard to the open space set aside, several people spoke about wildlife at the site. Local resident Richard Palmer (the president of the homeowners’ association for the subdivision just south of Dove Hill) presented a letter from an area habitat biologist with the Washington State Department of Fish and Wildlife addressed to Mr. Palmer. The biologist’s letter stated that adequate open space within the Dove Hill subdivision was critical to survival of [749]*749wildlife species. The biologist referred to a conversation with Palmer where Palmer told the biologist that several wildlife species had been seen at the site, including the pileated woodpecker, a candidate for listing as threatened, endangered or sensitive,4 and the ringneck snake, which had been found in Clark County only at one other location and was classified as a monitored species. The letter stated that Fish and Wildlife recommended that the full 30 percent set aside be required. Another resident also referred to this letter and urged that the full 30 percent set aside for open space be required.
Isla Verde objected to the secondary access road requirement, stating that satisfying the condition was impossible because Isla Verde would be unable to obtain easements over neighboring property to construct the road. As to open space, as noted, Isla Verde proposed less than a 30 percent set aside,5 with a “buy down” to make up the difference. Isla Verde also objected to any separate impact fees for parks and open spaces. Chapter 3.88 CMC provides for imposition of impact fees to help pay for the cost of public facilities to serve new growth and development, and CMC 3.88.070 specifically allows impact fees for park and recreational facilities and open space.
The City Council decided to delay its decision until after an on-site visit, which occurred July 5, 1995. The Council then initially voted to deny Isla Verde’s application because of fire safety concerns, but on July 24,1995, reconsidered. It approved the preliminary plat application subject to the condition recommended by the Planning Commission for a secondary limited access road. It did not, however, specify where this road must be constructed. The City Council also [750]*750required a full 30 percent open space set aside, with no “buy down.” The City’s decision on the application does not mention any impact fees imposed pursuant to chapter 3.88 CMC.
Isla Verde petitioned for review of the City’s decision under the Land Use Petition Act (LUPA), chapter 36.70C RCW. Following review, the Clark County Superior Court entered an order holding that the secondary access road condition violates substantive due process and chapter 64.40 RCW, because the condition is impossible to satisfy, unduly burdensome, arbitrary and capricious, and denies all viable use of the property. The court held that the open space set aside constitutes a taking under the state constitution and a violation of RCW 82.02.020 and chapter 64.40 RCW, because the City made no individualized determination that the 30 percent set aside requirement is necessary to mitigate an impact of the development, the condition is disproportionate to the impact caused by the subdivision, and the City has not established a need for additional open space within the city limits as a result of the proposed development. Finally, the court held that the City’s imposition of a parks impact fee and an open space impact fee was also unlawful, despite the lack of any such condition in the City’s written decision. The City sought reconsideration, offering evidence to show the reason for enactment of the open space ordinance with its 30 percent requirement. The superior court declined to consider the additional evidence and denied a motion for reconsideration.
The Court of Appeals affirmed the superior court’s ruling that the open space set aside condition constitutes an unconstitutional taking.6 The Court of Appeals upheld the secondary access road condition, however. Finally, that court concluded that since the City had not assessed any impact fees under chapter 3.88 CMC, the issue of whether they could lawfully be imposed was not ripe for adjudica[751]*751tion. Isla Verde Int'l Holdings, Inc. v. City of Camas, 99 Wn. App. 127, 990 P.2d 429 (1999). The City then sought discretionary review by this court.
ANALYSIS
Review is under the LUPA, chapter 36.70C RCW. This court stands in the same position as the superior court. Wenatchee Sportsmen Ass’n v. Chelan County, 141 Wn.2d 169, 176, 4 P.3d 123 (2000). Review is limited to the record before the City Council. Citizens for Responsible & Organized Planning v. Chelan County, 105 Wn. App. 753, 758, 21 P.3d 304 (2001); Kahuna Land Co. v. Spokane County, 94 Wn. App. 836, 841, 974 P.2d 1249 (1999). The potentially relevant standards of review in this case are set forth in RCW 36.70C. 130(1), which authorize invalidation of the City’s decision to impose the disputed conditions if that decision (1) is an erroneous interpretation of the law; (2) is not supported by substantial evidence; (3) is a clearly erroneous application of the law to the facts; or (4) violates the constitutional rights of the party seeking relief.7 The court may grant relief only if Isla Verde, the party seeking relief from the land use decision, has carried the burden of establishing that one of these standards has been met. RCW 36.70C.130. Statutory construction is a question of law reviewed de novo under the error of law standard. Wenatchee Sportsmen, 141 Wn.2d at 176. In order to conclude that substantial evidence supports the factual findings, there must be a sufficient quantity of evidence in the [752]*752record to persuade a reasonable person that the declared premise is true. Id.
Open Space Set Aside Condition
The first issue is whether the 30 percent open space set aside condition is valid. As noted, the superior court determined that the open space set aside condition on preliminary plat approval violates state constitutional and statutory provisions, including RCW 82.02.020. The Court of Appeals held that the condition violates the takings clause of the Fifth Amendment to the United States Constitution. Although the Court of Appeals decision rests on constitutional grounds, the condition violates RCW 82.02-.020, as the superior court determined. Accordingly the Court of Appeals should not have reached the constitutional question.
We adhere to the fundamental principle that if a case can be decided on nonconstitutional grounds, an appellate court should refrain from deciding constitutional issues. See State v. Speaks, 119 Wn.2d 204, 207, 829 P.2d 1096 (1992) (although Court of Appeals decided constitutional issue, this court declined to reach constitutional issue where case was resolvable on statutory grounds); Tunstall v. Bergeson, 141 Wn.2d 201, 210, 5 P.3d 691 (2000) (where issue may be resolved on statutory grounds, court will avoid deciding issue on constitutional grounds); Tommy P. v. Bd. of County Comm’rs, 97 Wn.2d 385, 391, 645 P.2d 697 (1982) (where case can be resolved on other grounds, court will not reach constitutional issue); Senear v. Daily Journal-Am., 97 Wn.2d 148, 152, 641 P.2d 1180 (1982) (same); Ohnstad v. City of Tacoma, 64 Wn.2d 904, 907, 395 P.2d 97 (1964) (same); see also Skagit Surveyors & Eng’rs, LLC v. Friends of Skagit Valley, 135 Wn.2d 542, 546, 958 P.2d 962 (1998) (because the case was decided on statutory grounds, constitutional issues were not reached); State v. Faford, 128 Wn.2d 476, 481, 910 P.2d 447 (1996) (same); In re Dependency of J.B.S., 123 Wn.2d 1, 7, 863 P.2d 1344 (1993) [753]*753(same); In re Pers. Restraint of Moore, 116 Wn.2d 30, 32, 803 P.2d 300 (1991) (same).
RCW 82.02.020 generally provides, with some exceptions, that the state preempts the field of imposing certain taxes. The statute then states, in relevant part: “Except as provided in RCW 82.02.050 through 82.02.090, no county, city, town, or other municipal corporation shall impose any tax, fee, or charge, either direct or indirect, on . .. the development, subdivision, classification, or reclassification of land.” RCW 82.02.020.8 There are, besides the involuntary impact fees permitted under RCW 82.02.050 through RCW 82.02.090,9 three exceptions to the prohibition against [754]*754direct or indirect taxes, fees or charges on the development or subdivision of land (or classification or reclassification). RCW 82.02.020 “does not preclude dedications of land or easements within the proposed development or plat which the county, city, town, or other municipal corporation can demonstrate are reasonably necessary as a direct result of the proposed development or plat to which the dedication of land or easement is to apply.” RCW 82.02.020. RCW 82.02.020 also permits voluntary agreements that allow a payment in lieu of dedication of land or to mitigate a direct impact that is a consequence of a proposed development, subdivision or plat. In both instances, payment may be required as part of a voluntary agreement only where the county, city, town, or other municipal corporation establishes it is reasonably necessary as a direct result of the proposed development or plat.10
[755]*755RCW 82.02.020 requires strict compliance with its terms. Trimen Dev. Co. v. King County, 124 Wn.2d 261, 270, 877 P.2d 187 (1994); R/L Assocs. v. City of Seattle, 113 Wn.2d 402, 409, 780 P.2d 838 (1989). A tax, fee, or charge, either direct or indirect, imposed on development is invalid unless it falls within one of the exceptions specified in the statute. Henderson Homes, Inc. v. City of Bothell, 124 Wn.2d 240, 247, 877 P.2d 176 (1994) (citing R/L Assocs., 113 Wn.2d at 409).
The superior court held that the open space set aside condition violates RCW 82.02.020 because there has been no individualized determination that the 30 percent set aside requirement is necessary to mitigate an impact of the development, the condition is disproportionate to the impact caused by the subdivision, and the City has not demonstrated any need for additional open space arising from the development. In his oral ruling, the superior court judge noted that the statute permits dedications of land or easements provided the City can establish that they are reasonably necessary as a direct result of the proposed development. He also noted the statutory requirement that payments in lieu of dedication also must be reasonably necessary as a direct result of the proposed development. The judge said, “I didn’t find anything in the record that showed that there was any consideration of the direct effect of this development to serve as a basis for imposing the 30 percent.” Verbatim Report of Proceedings (June 28,1996) at 102.
As noted, the burden of proof under RCW 36.70C-.130(1) is on Isla Verde, while under RCW 82.02.020 the [756]*756burden of establishing that a condition is reasonably necessary as a direct result of the proposed development is on the City. Keeping these burdens in mind, we address the arguments advanced by the City, the petitioner here, as to why the open space condition is a lawful condition. The City argues that the open space set aside does not violate RCW 82.02.020 because it does not impose a tax, fee or charge on development. Instead, the City maintains, the set aside is a police power based condition imposed pursuant to RCW 58.17.110.* 12********11 The City says that RCW 82.02.020 recognizes the authority of cities to require dedication for police power purposes, provided they are reasonably necessary as a direct result of the proposed development or plat. The City says that the necessary connection between a required dedication and the impact of Isla Verde’s proposed subdivi[757]*757sion has been established legislatively and by evidence in the record.12
Initially, although some of the City’s argument equates the open space set aside condition to a dedication for purposes of RCW 82.02.020, it maintains that the set aside is not actually a dedication.13 However, the question we must answer is whether the set aside constitutes a tax, fee or charge within the meaning of the statute. The meaning of RCW 82.02.020 is a question of law reviewed de novo. Wenatchee Sportsmen, 141 Wn.2d at 176; see also State v. Breazeale, 144 Wn.2d 829, 837, 31 P.3d 1155 (2001); State v. J.M., 144 Wn.2d 472, 480, 28 P.3d 720 (2001). The court’s fundamental objective is to ascertain and carry out the Legislature’s intent, and if the statute’s meaning is plain on its face, then the court must give effect to that plain meaning as an expression of legislative intent. J.M., 144 Wn.2d at 480. The question whether a tax, fee or charge is involved also involves application of the law to the facts.
For a number of reasons we disagree with the City’s assertion that the set aside condition is not a tax, fee, or charge within the meaning of RCW 82.02.020. The exclusionary language of the statute demonstrates that the prohibited charges are not limited to monetary charges. Specifically, the statute provides that a dedication of land or easement is excluded from the statute’s prohibitions if reasonably necessary as a direct result of the proposed development. The statute thus contemplates that a required dedication of land or easement is a tax, fee or charge. [758]*758Further, this court has recognized that for purposes of RCW 82.02.020 a tax, fee, or charge can be in kind as well as in dollars. San Telmo Assocs. v. City of Seattle, 108 Wn.2d 20, 24, 735 P.2d 673 (1987) (requirements that owners of low income rental units provide relocation notice and assistance, and replacement of a specified percentage of the low income housing with other suitable housing or contributing to the low income housing replacement fund in lieu thereof, when residential units are demolished or redeveloped to other use violated RCW 82.02.020 as indirect charge on development).
The open space condition here is comparable to conditions in a number of cases analyzed under RCW 82.02.020. E.g., Vintage Constr. Co. v. City of Bothell, 135 Wn.2d 833, 959 P.2d 1090 (1998) (RCW 82.02.020 applicable where ordinance required dedication of five percent of land for parks or payment of $400 per lot in lieu thereof; developer entered a “voluntary agreement” to pay in lieu fees) (adopting opinion of the Court of Appeals in Vintage Constr. Co. v. City of Bothell, 83 Wn. App. 605, 922 P.2d 828 (1996)); Trimen, 124 Wn.2d 261 (RCW 82.02.020 applicable where ordinance required dedication of land for open space or payment of fee in lieu thereof; developer paid in lieu fees under voluntary agreement); Henderson Homes, 124 Wn.2d 240 (RCW 82.02.020 applicable where condition required payment of $400 per lot park mitigation fee); United Dev. Corp. v. City of Mill Creek, 106 Wn. App. 681, 698-99, 26 P.3d 943 (RCW 82.02.020 applicable where condition required frontage improvements for drainage along adjacent boulevard), review denied, 145 Wn.2d 1002 (2001); Castle Homes & Dev., Inc. v. City of Brier, 76 Wn. App. 95, 882 P.2d 1172 (1994) (RCW 82.02.020 applicable where voluntary agreement required payment of $3,000 per lot or provision of offsite traffic improvements); View Ridge Park Assocs. v. City of Mountlake Terrace, 67 Wn. App. 588, 839 P.2d 343 (1992) (RCW 82.02.020 applicable where ordinance required developers to construct onsite recreational facilities or pay a fee in lieu thereof). Indeed, the Camas ordinance [759]*759authorizing the set aside condition is quite similar to the ordinance at issue in Trimen, which required a dedication or reservation of open space, or a fee in lieu thereof.
We conclude that the open space set aside condition is an in kind, indirect “tax, fee, or charge” on new development.
The next question is whether the 30 percent set aside is unlawful under RCW 82.02.020 or whether it falls within an exception. It is, as explained, Isla Verde’s burden to show that one of the standards in RCW 36.70C. 130(1) applies and requires invalidation of the open space condition. Under RCW 82.02.020, however, the City has the burden of showing that one of the statute’s exceptions applies. With these principles in mind, we address the City’s justifications for imposing the open space condition.
As mentioned earlier, the City maintains that the open space condition does not require an actual dedication of land to public use. Nevertheless, the City argues that the exception allowing dedication where reasonably necessary as a direct result of the proposed development of plat does apply in this case, and thus no violation of RCW 82.02.020 exists. The City more directly argues that the open space condition is authorized to mitigate direct impacts of the proposed development.
We need not decide whether the set aside provisions require a dedication of land for purposes of the exceptions in RCW 82.02.020 because the City has failed to establish that the 30 percent open space set aside is reasonably necessary as a direct result of the proposed subdivision or reasonably necessary to mitigate a direct impact that is a consequence of the proposed subdivision. We note, however, the possibility that just as a tax, fee, or charge on development may be, in kind, a required set aside of the sort required under CMC 18.62.020 and might be deemed equivalent to a dedication for purposes of the statute, given the Legislature’s obvious intent to allow charges on devel[760]*760opment where the need for them is a direct result of the development.14
The City first urges that its set aside requirement falls within the statutory exception because it has made a valid legislative determination of the need for subdivisions to provide for open space set asides to mitigate consequences of subdivision development. The City relies on Trimen for the proposition that such a determination in and of itself satisfies its burden of proving the required connection between the development and the open space condition. The City misreads Trimen. In Trimen, the county conducted a comprehensive assessment of park needs in a report predating the developer’s applications for subdivision approval. Trimen, 124 Wn.2d at 274. That report showed a deficit of park acres in the area of the proposed developments and projected a greater deficit as population expanded. Id. A dedication or reservation of open space at the figure negotiated by the parties would have resulted in an amount of park land roughly proportional to that which the report showed would be needed for the developments’ estimated population. Id. The fees in lieu of dedication were thus upheld by this court. Importantly, and contrary to the City’s argument here, we said that the county’s “fee in lieu of dedication is calculated based on zoning, projected population, and the assessed value of the land that would have been dedicated or reserved. [The county’s] assessment of fees in lieu of dedication are specific to the site.” Id. at 275.
Thus, in Trimen the fees imposed were reasonably necessary as a direct result of the proposed subdivisions, i.e., the need for park land was directly attributable to the projected population of the developments and the fees were calculated based upon the value of land that would otherwise be required to be dedicated or reserved for parks to [761]*761serve the developments’ populations. Trimen does not support the City’s argument that a legislative determination of the need for open space satisfies the exceptions in RCW 82.02.020.
Nor does RCW 82.02.020. The statute mandates that a municipality must demonstrate that a dedication is “reasonably necessary as a direct result of the proposed development or plat,” and also mandates that, in the case of a payment in mitigation of a “direct impact that has been identified as a consequence” of the proposed development, a municipality must establish that the payment is “reasonably necessary as a direct result of the proposed development or plat.” RCW 82.02.020 (emphasis added). We have repeatedly held, as the statute requires, that development conditions must be tied to a specific, identified impact, of a development on a community. Vintage Constr. Co., 83 Wn. App. at 611-12, opinion adopted in Vintage Constr. Co., 135 Wn.2d 833; Trimen, 124 Wn.2d at 275; Henderson Homes, 124 Wn.2d at 242-44. RCW 82.02.020 does not permit conditions that satisfy a “reasonably necessary” standard for all new development collectively; it specifically requires that a condition be “reasonably necessary as a direct result of the proposed development or plat.” (Emphasis added.) We reject the City’s argument that it satisfies its burden under RCW 82.02.020 merely through a legislative determination “of the need for subdivisions to provide for open space set asides ... as a measure that will mitigate a consequence of subdivision development.” Am. Br. of Appellant at 38.
The City also contends, however, that its steep slopes ordinance supports imposition of the open space condition as a mitigation measure. Under the steep slopes ordinance, if a development site has steep slopes it is an environmentally sensitive area, a geotechnical report is required, and mitigation measures may be required. Former CMC 18.61.020(D), (E), (F), (I). The City points out that the open space ordinance states that open space areas should include “environmentally sensitive areas.” Former CMC 18.62-.020(C). Isla Verde’s property has steep slopes.
[762]*762One difficulty with the City’s contention is that the record does not establish that under the steep slopes ordinance any of the steep slopes here are greater than allowed for development. Former CMC 18.61.050(B)(1). In addition, the geotechnical report prepared for the proposed development concludes that the “property is not within nor part of a potentially unstable slope area.” Dove Hill Subdivision File Records at 277. We note that a determination of nonsignificance was issued under the State Environmental Policy Act, chapter 43.21C RCW.15 Most importantly, while there may be some negative impact on environmentally sensitive areas, the record does not reveal the extent or significance of such an impact. There is no showing on this record that as to this property a 30 percent open space set aside is reasonably necessary to mitigate development impacts on environmentally sensitive steep slopes.
The City next asserts that the record shows a proposed conversion of wooded property to developed property, impact on wildlife, and the City’s recent past practice to favor the full 30 percent set aside over “buy downs” justify the 30 percent open space condition for subdivision approval. The City also refers to the City Administrator’s letter that describes a 30 percent set aside as conforming to the City’s open space network (since the property is wooded, has steep slopes, and wildlife habitat). None of the evidence to which the City refers shows any relation between a 30 percent open space requirement and impacts or effects of Isla Verde’s proposed development. Again, it is arguable that there will be some impact on wildlife habitat, and certainly clearing wooded land to build houses will affect the wooded nature of the site. However, there is no showing that a 30 percent open space set aside is required to address these impacts. The fact that the City has recently imposed the full 30 percent set aside rather than allowing “buy downs” is [763]*763irrelevant; it says nothing about why an open space set aside is necessitated by a particular proposed subdivision.
Instead, the open space condition to obtain plat approval is uniformly applied, in the preset amount, regardless of the specific needs created by a given development. The fees or charges authorized under the exceptions in RCW 82.02.020, whether direct or indirect, may not be imposed automatically, but must be tied to a direct impact of the proposed development. See Henderson Homes, 124 Wn.2d 240 (payment of a preset $400 per lot fee as a park mitigation fee invalid); Vintage Constr. Co., 83 Wn. App. 605, opinion adopted in Vintage Constr. Co., 135 Wn.2d 833 (condition requiring dedication of five percent of land for park or payment of $400 per lot invalid). Aside from the ordinance requiring a flat 30 percent set aside for every proposed subdivision, there is nothing in the record explaining why 30 percent was chosen as the amount of open space needed in this case.16
Finally, the City’s claim that RCW 58.17.110 provides police power authority to impose the open space condition does not validate the condition. RCW 58.17.110 requires local governments to ensure that proposed plats make appropriate provisions for the public health, safety and welfare, including open spaces. Although local governments are encouraged to require developers to set aside open space under this statute, nowhere does the platting statute authorize an across the board 30 percent set aside for open space. Recognizing that local governments have the authority to adopt regulations or to withhold plat approval if appropriate provisions have not been made, courts have interpreted RCW 58.17.110 as allowing such [764]*764conditions only where the purpose is to mitigate the problems caused by the particular development. Southwick, Inc. v. City of Lacey, 58 Wn. App. 886, 892-93, 795 P.2d 712 (1990). Indeed, the City agrees that conditions imposed in accord with RCW 58.17.110 must be necessary as a direct result of the development. RCW 58.17.110 does not authorize the City’s condition in this case.17
We conclude that the open space set aside condition does not fall within any exception in RCW 82.02.020.
The City also relies on RCW 35A.63.100 as authority for its 30 percent open space condition. That statute provides municipal authority to code cities to divide the municipality
into appropriate zones within which specific standards, requirements, and conditions may be provided for regulating the use of public and private land, buildings, and structures, and the location, height, bulk, number of stories, and size of buildings and structures, size of yards, courts, open spaces, density of population, ratio of land area to the area of buildings . . . setbacks ....
RCW 35A.63.100(2) (emphasis added). As the statute states, ordinances enacted under its authority are “zoning ordinance [s].” Id. Although its preamble states that Camas Ordinance 1820 (1991), which includes former CMC 18-.62.020, amends the zoning code to provide for an overlay zone, the body of the ordinance does not simply treat the open space requirement as a zoning requirement. Former CMC 18.62.010(A) first states that the open space condition will be required in areas shown on the zoning map with a use classification of “P.” However, it then states, u[i]n addition, the standards and requirements of this chapter [765]*765shall apply to any application or proposal involving a planned unit development, subdivision or short subdivision, or any site with a portion of the site designated for the Open Space Network.” Id. (emphasis added). The open space ordinance thus applies to any subdivision, regardless of zoning, as a condition for subdivision approval, and, as explained, its application here burdens development in the way that is proscribed under RCW 82.02.020.
We hold that the 30 percent open space set aside condition for approval of Isla Verde’s plat application violates RCW 82.02.020 and is therefore invalid.
Secondary Access Road Condition
In its answer to the petition for review, Isla Verde contends that the Court of Appeals erred in upholding the constitutionality of the City’s conditioning approval of Isla Verde’s plat application on provision of a secondary access road for emergency vehicle use. Isla Verde contends that the condition is impossible to perform and illegally delegates a veto power to the neighbors, and therefore its imposition violates substantive due process. Isla Verde’s argument rests on the premise that the access road must be constructed on property to the east of the proposed development, and the owner of that property has stated that she will never grant an easement for a secondary access road. Isla Verde also says that the condition constitutes a taking, because the property is not suitable for any other purpose and therefore imposing a condition on subdivision development that is impossible to perform deprives it of any economically viable use for the property. We agree with the Court of Appeals that the record does not support Isla Verde’s claim of impossibility, and therefore its constitutional challenges to the secondary access road condition fail.
Initially, we emphasize that the City’s decision does not mandate that the secondary access be provided by a road over the property to the east, as Isla Verde has claimed. [766]*766While a city staff report proposed that condition, the City Council’s final decision provides only that “the applicant provide a secondary access to the subject real property that is sufficient to permit utilization by emergency vehicles and that satisfies the standards of the Uniform Fire Code for fire apparatus access roads.” Dove Hill Subdivision File Records at 149.
Before approving a subdivision development a local governmental entity must consider the adequacy of access to the proposed development and may condition approval of a plat on provision of adequate access. Lechelt v. City of Seattle, 32 Wn. App. 831, 835, 650 P.2d 240 (1982); see RCW 58.17.110. However, while a municipality has authority to make appropriate provisions for the public health, safety, and welfare, and to condition plat approval accordingly, it does not have authority to require a developer “ ‘to shoulder an economic burden, which in justice and fairness the public should rightfully bear.’ ” Weden v. San Juan County, 135 Wn.2d 678, 706, 958 P.2d 273 (1998) (quoting Orion Corp. v. State, 109 Wn.2d 621, 648-49, 747 P.2d 1062 (1987)).
The burden of proving a violation of substantive due process is on Isla Verde. Christianson v. Snohomish Health Dist., 133 Wn.2d 647, 659-61, 946 P.2d 768 (1997). A land use regulation is not violative of substantive due process where (1) the regulation aims to achieve a legitimate public purpose; (2) the means adopted are reasonably necessary to achieve that purpose; and (3) the regulation is not unduly burdensome on the property owner. Presbytery of Seattle v. King County, 114 Wn.2d 320, 331, 787 P.2d 907 (1990). Isla Verde concedes that a secondary access road for emergency vehicles serves a legitimate public purpose. The concession is appropriate. See, e.g., Kahuna Land Co. v. Spokane County, 94 Wn. App. 836, 843, 974 P.2d 1249 (1999) (a requirement that there be adequate access to a subdivision serves a legitimate public purpose).
Isla Verde contends, however, that the means to achieve the public purpose are unreasonable. Isla Verde character[767]*767izes the decision to require a secondary access road as the City’s “mere desire” to have a second road. Moreover, Isla Verde argues, it is not reasonable to require an impossible or oppressive condition.
The record demonstrates that an additional access route is reasonably necessary to provide fire protection for the residents of the new Dove Hill subdivision. Testimony established that Dove Hill is located in a hazardous fire area and Sierra Lane alone would provide inadequate access to the proposed subdivision in the event of a fire. The testimony of the Camas Fire Marshal and that of a number of local residents was that Sierra Lane can become impassable in inclement weather. The Camas Fire Marshal also testified that Sierra Lane is inadequate under current code requirements for emergency vehicle access. Dove Hill, with its proposed 51 lots, will certainly add to the need for adequate fire and other safety protection; Isla Verde’s proposed development will significantly increase the population that must be served. Fire and other rescue vehicles must have adequate access for emergency purposes, and Sierra Lane is not adequate to provide such access to the proposed subdivision.
Although Isla Verde complains that the condition is impossible to satisfy, it relies solely on the testimony of one neighbor to the east who has stated that she will not grant an easement for construction of a secondary access road over her property. There is no evidence that Isla Verde has made any attempts to secure this or any other property prior to filing this suit. Even if this particular property is unavailable, Isla Verde has not shown that all reasonable efforts to meet the secondary access road condition would be frustrated. Moreover, while Isla Verde also cites testimony that it says supports its conclusion that there is no access from the north, it fails to note that the testimony actually indicates a possible alternate route. CP at 252-53.
Thus, Isla Verde has not established that the selected means of achieving a legitimate public purpose—a secondary access road for emergency vehicles—is unreasonable, [768]*768either as a mere desire for a second road or as an impossible condition to meet.
As to the third factor in the substantive due process analysis, we consider the (a) nature of the harm to be avoided; (b) the availability and effectiveness of less drastic measures; and (c) the economic loss suffered by the property owner. Presbytery of Seattle, 114 Wn.2d at 331. Other nonexclusive factors that may be helpful in the balancing required under the third factor include the seriousness of the public problem, the extent to which the landowner’s property contributes to the problem, the degree to which the regulation solves the problem, and the feasibility of less burdensome solutions. Id.
The harm to be avoided is an uncontrolled fire within the proposed subdivision or the need for a rescue or other emergency assistance. The problem is serious because, as the record establishes, Sierra Lane is inadequate and human life and property are at risk. Isla Verde maintains, though, that the problem of inadequate access via Sierra Lane existed prior to its proposed development, and it has not contributed to the need for a secondary access road. As explained above, however, the increased population of the proposed subdivision exacerbates the problem, creating a greatly increased risk of harm. The record does not show any less drastic solution that would be as effective as providing a secondary access road.18
Isla Verde also contends that the condition is economi[769]*769cally fatal to its development. As noted, Isla Verde claims that the condition is impossible to comply with because the neighbor to the east has said she will grant no easement, and thus, Isla Verde maintains, it cannot satisfy the condition and cannot develop its property. As explained, the record does not support Isla Verde’s claim of impossibility. While Isla Verde has also argued that any alternate route would be excessively expensive, it cites to no evidence that backs this claim.
Finally, because the condition does not specify any particular access, it clearly does not grant a veto to the neighbor to the east, contrary to Isla Verde’s contention. We therefore do not reach the question of the validity of a condition that did grant a “veto.”
We conclude, after balancing the various factors, that the secondary road access condition does not violate substantive due process.
Isla Verde also argues that the condition is arbitrary and capricious because it cannot be performed, and all uses on the property are therefore denied. In addition to arguing that substantive due process is thus violated, Isla Verde also argues that chapter 64.40 RCW is violated.
RCW 64.40.020(1) states that “[o]wners of a property interest who have filed an application for a permit have an action for damages to obtain relief from acts of an agency which are arbitrary, capricious, unlawful, or exceed lawful authority.” As the Court of Appeals held, the City’s act in imposing the secondary access road condition was not arbitrary or capricious. An act is arbitrary or capricious if it is a “ ‘ “wilful and unreasonable action, without consideration and regard for facts or circumstances.” ’ ” Landmark Dev., Inc. v. City of Roy, 138 Wn.2d 561, 573, 980 P.2d 1234 (1999) (quoting Teter v. Clark County, 104 Wn.2d 227, 237, 704 P.2d 1171 (1985) (quoting Miller v. City of Tacoma, 61 Wn.2d 374, 390, 378 P.2d 464 (1963))). “ mere there is room for two opinions, action is not arbitrary or capricious when exercised honestly and upon due consideration ....’” Landmark Dev., 138 Wn.2d at 573 (quoting DuPont-Fort [770]*770Lewis Sch. Dist. No. 7 v. Bruno, 79 Wn.2d 736, 739, 489 P.2d 171 (1971)).
As explained above, the record does not support Isla Verde’s contention that the secondary road access condition is impossible to comply with, and thus the City’s action in imposing the condition is not arbitrary or capricious on that ground. Further, when making its decision, the City visited the development site, considered all the evidence, including the Fire Marshal’s testimony and recommendations, and the testimony of residents about the poor road conditions of Sierra Lane during winter weather, and additionally considered the problems posed by the topography of the site. The record shows that the City’s concerns about public safety in the absence of a secondary access road are legitimate. The City made a reasonable decision when it required Isla Verde to provide a secondary access road for emergency vehicles. We conclude that chapter 64.40 RCW was not violated.
Our analysis makes it unnecessary to address Isla Verde’s summary contention that the secondary road access condition constitutes a taking. Because Isla Verde has not supported its claim that compliance is impossible, it has not shown that it is left with no viable economic use of the property.
Finally, we agree with the Court of Appeals that because the City has not actually imposed any parks and open space impact fees, Isla Verde’s challenges to the imposition of any such fees is not ripe for judicial review. There is no land use decision reviewable under the LUPA. See RCW 36.70C.020; see also Rhod-A-Zalea & 35th, Inc. v. Snohomish County, 136 Wn.2d 1, 959 P.2d 1024 (1998) (insofar as constitutional challenge is made). Therefore, we do not address the propriety of any such fees.
CONCLUSION
The City’s condition on plat approval that Isla Verde set aside 30 percent of its property as open space violates RCW [771]*77182.02.020 and is therefore invalid. Isla Verde has failed to establish that the City’s condition that Isla Verde provide secondary access for emergency vehicles violates substantive due process or is arbitrary and capricious in violation of chapter 64.40 RCW. Accordingly, we uphold that condition. The Court of Appeals decision as to these conditions is affirmed, and this matter is remanded for further proceedings.
