Sam Bass Road Drainage Issues. Needed Changes brought to City Council by Willow Park Citizens.
Update: During the 23 December 2023 Council Meeting, this issue was addressed by the City. Willow Park Civics will post details of the City's report on the Sam Bass Drainage Issues and on Willow Park citizen's responses to the City plans.
Several Residents of Sam Bass Road have set an example for all Willow Park Citizens on how to bring an issue to the City Council.
During the 14 November 2023 Council Meeting, Public Comments, Dave Laurenzo and Cindy Voorhees of Sam Bass Road spoke of the drainage issues on Sam Bass Drive and on West Stagecoach Trail. Some of the current drainage issue are caused by the current City road improvements on Sam Bass Road and some issues are long standing issues, caused by gas pipeline owners of City street utility easements.
Laurenzo's presentation (below and in .pdf and at 5:47 of the meeting Facebook video) gave the Sam Bass Road drainage history, details, plans for needed changes, including detailed photos, and a specific request to the City Council to place these drainage issues on the Council agenda, "for discussion and action."
The presentation succeeded on the first request of Council attention; during Informational Council Comments of the 14 November 2023 Council Meeting, Mayor Pro Tea asked the City Administrator to research and bring details to the Council. In addition, during the 28 November 2023 Council Meeting, Mayor Pro Tem Young requested an update from Staff on drainage issues that have been brought to the city council and for this agenda item to be placed on an immediate council agenda.
