New London — Contractors started a citywide street sweeping initiative this week, a project funded by the newly formed Stormwater Authority.

The sweeping started Tuesday in the south end and will progress to other parts of the city over the next two weeks. Where needed, temporary no parking signs will be posted 24 hours in advance of the sweeping.

The project is funded through a stormwater enterprise fund, whose revenue is derived from newly established fees on property owners based on the amount of impervious surface.

Joe Lanzafame, the director of public utilities, said the project, along with cleaning of catch basins, is part of the effort to meet requirements of the Municipal Separate Storm Sewer System, or MS4, permit issued by the state Department of Energy and Environmental Protection, which is mandated under the federal Clean Water Act.
