delivered the Opinion of the Court.
We granted certiorari to review the court of appeals decision in
Brannan Sand & Gravel Co. v. Federal Deposit Insurance Carp.,
I.
Designer Properties (Designer) sought to develop vacant property in Westminster, Colorado, as part of the Walnut Grove subdivision. Between November 9, 1980, and November 21, 1986, Designer submitted four subdivision plats for Westminster’s approval. 2 As a condition for Westminster’s approval of the plats, Designer agreed to dedicate land for the construction of streets and sidewalks as well as perpetual easements for the installation, operation, and maintenance of various public utilities. The last of these subdivision plats and dedications was accepted by Westminster and recorded with the Jefferson County Clerk and Recorder on December 10,1986.
Westminster also conditioned its plat approval upon Designer’s construction of certain subdivision improvements. Between February 11, 1980, and December 1, 1986, Designer and Westminster entered into three separate subdivision improvement agreements for the filings in the Walnut Grove subdivision. Under the terms of the subdivision improvement agreements, Designer was to pave roads, erect street lighting and traffic control devices, construct concrete curbs, gutters and water and sewer lines, and provide landscaping all at Designer’s expense and subject to Westminster’s approval. Designer contracted with Brannan to do the paving work under the subdivision improvement agreements. Upon completion of the work, Brannan billed Designer $208,-043.33, which Designer did not pay. Designer subsequently declared bankruptcy.
On July 28, 1988, Brannan filed a mechanic’s lien upon the subdivision filings naming both Designer and Westminster as owners of the property. Brannan subsequently filed suit on August 29, 1988, designating Westminster as a defendant. In response to Brannan’s complaint, Westminster filed a C.R.C.P. 12(b)(5) motion to dismiss, claiming inter alia that a mechanic’s lien cannot be filed against public property. After ruling that Westminster’s motion should be treated as a motion for summary judgment pursuant to C.R.C.P. 56, the district court granted Westminster’s motion for summary judgment, finding that Brannan’s mechanic’s lien could not attach to public property.
The court of appeals reversed, holding that there were genuine issues of material fact concerning whether the priority date of Brannan’s mechanic’s lien preceded the dedication and acceptance of the public improvements. The court of appeals explained its decision as follows:
Plaintiff asserts that it is entitled to a priority date preceding the dedication by developer and acceptance by the City. The City, however, argues on appeal that it takes free of any prior encumbrances upon dedication to a public use by developer and acceptance by the City. However, we are unaware of any authority for that assertion.
The trial court did not address the issue of whether plaintiff had perfected a valid mechanic’s lien or its priority. In our view, these circumstances require the cause to be remanded.
Brannan,

Westminster contends that the court of appeals erred when it reversed the district court’s order granting its motion for summary judgment. Specifically, Westminster
The primary purpose of a mechanic’s lien is to benefit and protect those who supply labor, materials, or services in order to enhance the value or condition of another’s property.
See Thirteenth St. Corp. v. A-l Plumbing & Heating Co.,
[t]he mechanics’ hen statutes provide that an effective mechanic’s hen relates back in time to the “commencement of work” upon the construction project at issue, thus gaining a preference over other hens and interests in land which may have been recorded prior to the actual filing of the mechanic’s hen.
Trustees of Mortgage Trust of America v. District Court,
Under Colorado common law, pubhc property was not susceptible to foreclosure and, consequently, pubhc property was not subject to mechanics’ hens.
See Fladung v. City of Boulder,
Excluding the lands owned by pubhc utilities from the encumbrances of hens for the payment of assessments merely reflects the general law that a hen ordinarily does not attach to such properties nor can the property be sold on foreclosure.
Fladung,
165 Colo, at 252,
Because Brannan’s cause of action concerns a mechanic’s hen filed against property owned by a pubhc entity, Brannan is requesting that we ignore the common law rule prohibiting the liening of pubhc property. Although the court of appeals recognized the existence of the common law rule, it held that application of the “relate back” provision in section 38-22-106(1) created a genuine issue of material fact as to whether the priority date of Brannan’s mechanic’s hen preceded the dedication and acceptance of Westminster’s property. This left open the question of whether a pubhc entity takes property subject to already existing hens.
See Home Bldg. Corp. v. Ventura Corp.,
Nothing in the mechanics’ hen statutes indicates that the General Assembly sought to eliminate the common law rule which prohibits the filing of mechanics’ hens against pubhc property. To the contrary, the General Assembly has enacted separate statutes designed to protect contractors who supply labor and materials to pubhc works projects.
See
§§ 38-26-101 to -107, 16A
Additionally, we note that the facts of this ease are not so unfair as to warrant judicial departure from the common law rule.
See Normandy Estates Metro. Recreation Dist. v. Normandy Estates Ltd.,
Our holding that a mechanic’s hen cannot be filed against pubhc property prevents Brannan from availing itself of the “relate back provision of section 38-22-106(1) in order to obtain a priority date preceding dedication and acceptance of Westminster’s property. Additionally, we need not consider the issue of whether a municipality takes property subject to already existing liens because Brannan filed its mechanic’s lien more than nineteen months after the final subdivision plat was dedicated and accepted for public use.
See Home Bldg. Corp.,
III.
We hold that the common law rule that a mechanic’s hen cannot be filed against pubhc property prohibits a contractor from attaching a hen to previously dedicated subdivision property intended for pubhc use. Consequently, the mechanics’ hen statutes are inapplicable to such a hen, thereby preventing any operation of the “relate back” provision of section 38-22-106(1) to estabhsh a priority date prior to the dedication and acceptance of the subdivision property. For this reason, the district court properly granted Westminster’s motion for summary judgment. Accordingly, we reverse the court of appeals with directions to reinstate the district court’s order.
Notes
. We granted certiorari on the following issue:
Did the court of appeals err in interpreting the Colorado General Mechanic’s Lien Law in a way that permits a mechanic's lien to be filed against previously dedicated public streets on the theory that such liens "relate back” to a time before the streets were dedicated for public use and ownership?
. These filings consisted of Walnut Grove Subdivision Filings 5, 6, 7, and 9.

the Missouri Supreme Court held that a municipal housing authority purchasing housing units from a builder took the units subject to already existing liens on the property.
