The proposed Denver ordinance, scheduled to be heard Tuesday by the City Council, would prohibit new gas stations from being built within 300 feet of a protected, low-intensity residential district or from within a quarter-mile of existing gas stations or rail stations.

Construction of new gas stations will be significantly limited in Denver after City Council approved an ordinance enacting the restrictions in a meeting Tuesday.

A Denver plan to constrict where developers can build gas stations could scuttle up to $50 million in pending projects.
