tak, chodzi o klauzulę zachowania praw wydobywczych, czyli przekazanie działki bez praw do wydobycia surówców mineralnych:
"3.06.020 Retention of Mineral Rights
In all instances where the City disposes of surplus real property when the City owns the mineral rights, the instrument of conveyance shall contain the following reservation, retaining for the City such rights:
EXCEPTING therefrom all oil, gas and other hydrocarbon substances and minerals lying below a depth of 500 feet from the surface of said land, but without the right of surface entry at any time upon said land or within the top 500 feet thereof, for the purpose of exploiting, developing, producing, removing and marketing said substances."
