Notwithstanding any other provision of law, owners of property abutting streets, avenues, roads, or alleys to be improved, or to have curbs, gutters, sewers, or sidewalks constructed thereon, shall not be required to make any deposit, nor shall the abutting property be assessed any part of the cost, for the improvement of the streets, avenues, roads, or alleys, or the construction of curbs, gutters, sewers, or sidewalks if the following conditions exist: The abutting property is Class 1 Property; and The abutting Class 1 Property, as evidenced by the most current certificates of tax assessment, is less than 80% of the median assessed value of all Class 1 real property in the District as reported by the Mayor; or The real property is exempt from the real property tax in the District pursuant to § 47-1002; or The Mayor determines that circumstances exist that threaten the health and safety of the public and that improvement of the streets, avenues, roads, and alleys, or the construction of curbs, gutters, sewers, or sidewalks thereon, is necessary to protect the health and safety of the public. The Mayor has sole discretion in the determination of which streets, avenues, roads, and alleys are to be improved, or which streets, avenues, roads, and alleys are to have curbs, gutters, sewers, or sidewalks constructed thereon where the exemption in subsection (a) of this section would be granted to owners of abutting property.
