City Ordinance does not list a stop sign at this location. All requests for new stop sign locations need to be made through the City Council.

Thank you, there is a proposal before the Mayor and his delegates concerning the acceptance and paving of the middle section of Longfellow Ave between Scott and East Bacon, the proposal is still in the preliminary investigative stage, it includes a proposed stop signs be located at northern leg of Longfellow at Scott St and at Collins St. Hopefully this proposal will resolve the original posters concern.
