NOTE: Prior to this latest repeal and reenactment, 21 Guam Code Ann. § 61501 contained a table of Yard and Lot Areas, which were a part of § 17200 of the Govt. Code (the source of this Section) as amended by P.L. 15-057:7 (Aug. 24, 1979). This section, as repealed and reenacted, contains no such table. Because this table still has potential use, the Compiler has included the Table as adopted by P.L. 15-057 below.
