Opinion by
1 1 Plаintiff, Walter G. Burkey Trust (the Trust), appeals a district court judgment affirming the Denver Board of Adjustment for Zoning Appeals (the Board) decision upholding the citation issued to the Trust by the City and County of Denver (the City) for violation of a zoning ordinance regarding a vacant lot used for parking. We affirm.
I. Background
T2 The Trust owns a vacant lot located at 1476 King Street in Denver (the lot). The lot was located in a district zoned R-2 before being rezoned to MS-2 in 2007. In the mid-1980s, the Trust used the lot for surface parking for the adjacent businesses the Trust owned. Surface parking was not a legal use in the R-2 zoned district, The lot was never legаlly authorized for parking before the 2007 zoning amendment.
T3 In 1987, the City issued the Trust two citations for using the lot for surface parking in violation of the zoning ordinance. The lot was still used for parking in 2008 following the 2007 amendment.
T 4 On November 18, 2008, the City issued an Order to Cease and Desist (the Order) parking use of the lot. The basis for the Order was that, under the new MS-2 zoning, surface parking lots werе not permitted unless they were existing legal uses.
T5 The Trust appealed the 2008 Order to the Board. The Board found in favor of the City. The Trust then sought judicial review pursuant to C.R.C.P. 106(a)(d) in the district court, and the district court upheld the Board's findings. The Trust now aрpeals the district court's decision.

III. Analysis
T7 The Trust contends that, pursuant to the amended zoning ordinance, its lot use was converted to a legal nonconforming use becаuse the lot and its use existed before the 2007 amendment. We disagree.
18 If an ordinance is susceptible of more than one reasonable interpretation, it is ambiguous and rules of construction may be used to interpret the ordinаnce. Dep't of Transp. v. Gypsum Ranch Co.,
T9 The amended zoning ordinance in question states:
Existing surface parking lots shall be legal nonconforming uses so long аs they existed by September 1, 2005, comply with chart 1, section 59-588 and plant and maintain street trees according to thе city forester's rules and regulations for such trees by June 30, 2009, or within nine (9) months of the property being re-zoned.... Surface parking is not a use by right.
Denver Rev. Mun. Code 59-277(8) (emphasis added). A legal nonconforming use is, in pertinent part, "any use which ... aftеr November 8, 1956 was lawfully operated in accordance with the provisions of this chapter." Id. at 59-681(a)(1) (emphasis added).
1 10 The City proposes reading these two sections of the ordinance together so that the Trust's prior illegal use of the lot for parking does not become a legal use as a result of the 2007 amendment. The Trust proрoses reading the amended ordinance section to allow the prior use to become a legal nonconforming use.
111 We agree with the district court that the language of the 2007 amendment is ambiguous and that both the City's and the Trust's intеrpretations are reasonable. Sierra Club v. Billingsley,
112 Whеn a term is defined in an ordinance, that definition governs, and it controls wherever the ordinance uses that term. See Colo. Water Conservation Bd. v. Upper Gunnison River Water Conservancy Dist.,
113 The record before thе Board shows that the lot was never legally used as a parking lot before the 2007 amendment to the zoning ordinancе. The Board considered this evidence, along with the definition of nonconforming use, and concluded that seetiоn 59-277(8) did not apply to the lot because the prior illegal use of the lot did not meet the definition of nonconforming use. The Board's interpretation that the 2007 ordinance grandfathered prior legal uses, but not existing illegal uses, has а reasonable basis. See Trailer Haven MHP,
4 14 Because the Board did not abuse its discretion or misapply a legal stаndard in determining whether the use of the lot qualified as a nonconforming use, the district court's well-reasoned judgment correctly affirmed the Board's decision.
1 15 Thus, the judgment is affirmed.
Notes
. The Trust owns two other lots on King Street that were legally used as surface parking lots for customers of the Trust's on-site businesses. These existing legal uses were allowed to continue even after the zoning ordinance amendments.
