Title
Update on infrastructure post-hurricane.
Summary:
Review of areas throughout town impacted by the Hurricane Hermine.
End
Body
Previous Commission Action: None.
Background/Problem Discussion:
Sanitary Sewer
The town had sanitary man hole overflows at Overbrook, south pine, and Melenbacher/Bluffview. Pinellas County was forced to relieve capacity from several lift stations, including at the north end of Hallett Park and Inside the RPD, where multiple homes had sewer backups. It appears that both the backups and the overflows were due to groundwater intrusion into the county sanitary sewer pipes and the impacts were felt countywide. County is currently performing smoke tests to find and fix points of intrusion.
Storm Sewer
New Construction since 2010
Belleview
All roads North of Belleview Blvd
Eagles nest/South Pine/Melenbacher West
Laurie/Meredith
Oleander
Pinellas/Althea - Saw high water tables at east end, some settling has occurred, but appears to be structurally insignificant
Manatee/Osceola
Roundabout
Under Current Construction
Bayview - Area held up well. Drainage seemed to work well.
Rosary - Saw a lot of washout which has been cleaned up. Crew came out several times to make road passable.
Areas of Note Outside of New Construction
Palmetto - Many roadway washouts, potholes being addressed to get us to project
Bayview from Bridge, East to IRR - During heavy rains, drainage system was overwhelmed, lot of overland flow. Issue is inlet at Palmview/Bayview and pipe going from that intersection to palmetto and eventually to the park. Did drain relatively quickly.
Indian Rocks Road - IRR S of Roundabout drained fairly quickly, but had a lot of puddling during the rains.
Poinsettia between Golfview and Cypress - Standing water in the road. System was being overwhelmed both within the creek, and within the conveyance between the creek and the golf course, and within the golf course itself.
Varona/Osceola - Standing water in the road. System was being overwhelmed both within the creek, and within the conveyance between the creek and the golf course
Ponce near Creek - The creek had a lot of water flow, which impacted transition of water into the creek, and caused some backups.
Ponce between Palmview and the Roundabout - Roadway did see deterioration, which has been packed and will be fixed during the Ponce/Palmview project
Carl Ave - Saw deterioration caused by ground water. Water seeping into roadway even after project.
